You want to know when another thread modifies the data. (If you have a reader/writer lock, you only want to be woken when someone exits a write.) Now, if you consider a producer/consumer queue. There are two interesting occurences. Transitions from empty to non-empty and transitions from full to non-full (optionally, if it is fixed size). Consumers wait for empty to non-empty. Consumers signal full to non-full. Producers wait for full to non-full. Producers signal non-empty to empty. So, in this case, one mutex is likely used with with two condition variables. But, what if we take a simplifying deoptimization and assume that a condition variable is only ever associated with one mutex? Anyone existing that mutex wakes up anyone waiting on any condition associated with it? Like, a condition variable I think becomes stateless and everything is about the mutex? What is the downside? Condition variables are allowed to have spurious wakeups. This would "just" increase them. Too much? So, therefore, what would be wrong with the following design? a mutex contains an event and a number of waiters, zero or non-zero if a mutex is exiting with a non-zero number of waiters, signal the event To handle Signal vs. Broadcast method 1: the number of waiters might be interlocked the woken would decrement it if it isn't zero, signal the event again method 2: the number of waiters is both an integer and a semaphore and the lock exiter raises the semaphore by the the integer method 3: it is not an auto-reset event and there is a count and when the count goes to 0, reset the event I think in this case you have to maintain a "wait generation" so that new waiters don't prevent the count from ever hitting 0. I think this #3 is what Java might be doing, and is described here: http://www.cs.wustl.edu/~schmidt/win32-cv-1.html "3.3. The Generation Count Solution" also: http://www.cs.wustl.edu/~schmidt/win32-cv-1.html 3.2.

Ok to make it contribute significantly to spurious wakeups? That is, I have this crazy theory...really need to come back to this fresh, try coding it, testing it..where you can implement a condition variable simply by waking everyone whenever a mutex is exited. I had this thought that what a condition variable represents is, instead of telling the kernel, here is one bit, an event, I am waiting for, instead you are telling it, hey, I have some custom code to evaluate, but it is false currently, and can only change when some exits such and such a lock, so just let me know when that lock is exited. The guy releasing the lock, or signal or broadcast..if he is signaling or broadcasting, he knows more specifically what he changed, not everything computable based on data protected by the lock, just something specific, but you can just wake everyone waiting on any of the conditions associated with the lock and it isn't maximally efficient but it should be correct. Basically, condition variable equals "wake me when someone changes some data and exits its lock". A better condition variable is that when there are multiple "conditions" in the data, the code making the change can target the wakeup better. But it isn't requires. And sometimes might not even matter much -- if in fact the ratio of locks to conditions is close to or equal to 1. - Jay CC: m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] condition variables/win32 Date: Thu, 8 Oct 2009 10:09:31 -0400 In general, it is OK in M3 to associate multiple conditions with the same mutex.

The Modula-3 spec (and the current pthreads-based implementation as also the win32 implementation I expect) do allow a condition variable being mediated by different mutexes. My comment was clouded by my recollection from the pthreads spec that for pthread mutex/cv behavior for other than 1 mutex per cv is undefined. This confusion may have been the source of prior bugs in the pthreads threading implementation, but those bugs are gone now. We support the M3 spec properly.

My concern is that if Juno is the only place where we have observed a problem, maybe the problem is with the Juno code and not with the threads implementation. That is why I was wondering if we had a non-Juno example that exhibits a problem. Having more than one exemplar may also help track down the problem. The modules I referenced in my prior message create higher-level abstractions. They are implemented using the primitives available in the language proper, no UNSAFE stuff. Of course, any efficiency improvement in the lower levels would be a benefit, and yes it is probable that recoding my abstractions at a lower level or making them features at a lower level would be more efficient. Note that I'm not suggesting that any of these abstractions be made features of the language or pushed down to the lower levels. I was just pointing out that I've got a lot of stuff that uses threading on Windows and I haven't observed that the threading implementation is broken.

Granted it might be related to "alert" which maybe isn't an often used feature? Any testing/testcases you can contribute, please do. We should probably have more primitives instead of building on top of what we have, as the lower levels are already fairly inefficient and building on them is probably even more so. -Jay Date: Thu, 8 Oct 2009 12:15:57 -0400 From: rcoleburn at scires.com To: m3devel at elegosoft.com Subject: Re: [M3devel] condition variables/win32 Jay: I have written and extensively tested a number of modules using threading. For example, I have a nice multi-reader, single-writer lock implementation, a gatekeeper implementation, an object-database implementation, etc. All of these are built on top of the thread primitives in Modula-3. So there is no need to reinvent the wheel here. If you need to see some of the code for these, let me know. Perhaps I can contribute some of these to the community. At this point, do we have any concrete example of a failure in the Win32 threading implementation, other than something mysterious with Juno? Regards, Randy >>> Jay K 10/8/2009 9:32 AM >>> condition variables/win32 So..one way I think about condition variables is that you want to be woken when someone else leaves the mutex that guards the data that you are dealing with. You want to know when another thread modifies the data. (If you have a reader/writer lock, you only want to be woken when someone exits a write.) Now, if you consider a producer/consumer queue. There are two interesting occurences. Transitions from empty to non-empty and transitions from full to non-full (optionally, if it is fixed size). Consumers wait for empty to non-empty. Consumers signal full to non-full. Producers wait for full to non-full. Producers signal non-empty to empty. So, in this case, one mutex is likely used with with two condition variables. But, what if we take a simplifying deoptimization and assume that a condition variable is only ever associated with one mutex? Anyone existing that mutex wakes up anyone waiting on any condition associated with it? Like, a condition variable I think becomes stateless and everything is about the mutex? What is the downside? Condition variables are allowed to have spurious wakeups. This would "just" increase them. Too much? So, therefore, what would be wrong with the following design? a mutex contains an event and a number of waiters, zero or non-zero if a mutex is exiting with a non-zero number of waiters, signal the event To handle Signal vs. Broadcast method 1: the number of waiters might be interlocked the woken would decrement it if it isn't zero, signal the event again method 2: the number of waiters is both an integer and a semaphore and the lock exiter raises the semaphore by the the integer method 3: it is not an auto-reset event and there is a count and when the count goes to 0, reset the event I think in this case you have to maintain a "wait generation" so that new waiters don't prevent the count from ever hitting 0.

I would second Randy's concern insofar as we should be able to add a test that exhibits the failure and then test any new implementation against it. At least that would be the proper way to do it. If you have a theory what breaks or where a race may be hidden, it should be possible to write a simple test, or isn't it? This again is just me with my release engineer's hat on :-) Also, if you have any tests that can be added to m3tests, please do!

Date: Thu, 15 Oct 2009 08:27:56 +0000 (GMT) Subject: [M3devel] Status of threads for RC4? In-Reply-To: Message-ID: <260188.52953.qm@web23603.mail.ird.yahoo.com> Hi all: I was merely thinking how we could mitigate the issue in threading. We could argue the current thread implementation issues on NT are worrisome but, the system performance is more important and I guess a release is waiting? for all platforms stability. I think we could make a work around to put some tests on the GUI subsystem on the test suite, using the sort of capability that Zeus Mentor Snapshot has to capture the screen shot and compare with others results with test already on: m3-ui/ui-tests m3-ui/ui/test Just getting some sort of difference between NT GUI subsystem and X implementation would allows to see where we can be missing something. Also integration on X implementation of Critical mass GUI upgrade would be highly appreciated: cm3-cvs/m3-ui/cmvbt Also I remember I saw the pm3 NT386GNU target implementation doing basic stuff with DEC SRC NT GUI, but? another doing advanced stuff with Mentor and others I think? the code you can get it by the package/src/ directories (http://www.1o0.de/wi-links/modula3/), but I?m not aware if it used the x/cygwin, I don?t think so, but even if so, would be an advance to have mentor running animation stuff until some point we could get better performance in the current NT GUI implementation (could be something in the garbage collection, Tony, as NT has its own garbage collector, has it been maintained after CM3 developed the new collector?) Another shot maybe for next release (7.0) is trying to develop tests on obliq framework and integration with pm3 documentation system, which seemed to be good. About Unix interfaces, Im thinking how to reuse the SPIN digital Unix interface so we can have a sort of a virtualization tool integrated in CM3 as a tool for deploying Unix apps on NT and getting some layers of Modula-3 runtime code based on a standarized Unix interface Sphinx.i3 (path in spin sources tree user/sphinx/src/IX86_SPIN/) something we could call "DECUnix.i3", we could also get some parts of the system running directly over Modula-3 runtime code rather than on bare Unix interfaces getting a more standarized behaviuor and maybe we could gain some knowledge to do experiments for system developers and users Thanks in advance --- El mi?, 14/10/09, Jay K escribi?: De: Jay K Asunto: Re: [M3devel] Status of threads for RC4?

This is very weird. All the threads are trying to acquire the same mutex (the global mutex in p007/src/Main.m3), but none of them is actually holding it. So, why can't one of them get it? Anyone else have any idea what's going on here?

A particular condition variable is always used in conjunction with the same mutex and its data. Doesn't this contradict the point made here? Does a condition variable always map to the same mutex or not? Or is this merely describing a typical usage pattern that is a subset of what interface Thread allows? 2) Can Wait only be satisfied by Signal/Broadcast, or also just via UnlockMutex? Depending on the answer to these questions, it seems you can largely merge mutex and condition variable. Condition variable is basically waiting for a thread to exit a mutex. Which is very very similar to LockMutex, except that it doesn't want to take the mutex in the uncontended case, it actually wants to wait for another thread to both acquire and release the mutex. I suspect I'm wrong on both of these. That condition variable really can use multiple mutexes. That exiting a mutex has no obligation to wake condition variables, though it might be in good faith to do so...er..if it is in good faith to not require programmer to use Signal/Broadcast.

The Modula-3 spec (and the current pthreads-based implementation as also the win32 implementation I expect) do allow a condition variable being mediated by different mutexes. My comment was clouded by my recollection from the pthreads spec that for pthread mutex/cv behavior for other than 1 mutex per cv is undefined. This confusion may have been the source of prior bugs in the pthreads threading implementation, but those bugs are gone now. We support the M3 spec properly.

So..one way I think about condition = variables

You want to = know when another thread modifies the data.
(If you have a = reader/writer lock, you only want to be

Now, if you consider a producer/consumer = queue.
There are two interesting occurences.
Transitions from = empty to non-empty
and transitions from full to non-full = (optionally,
if it is fixed size).
 

Consumers wait = for empty to non-empty.
Consumers signal full to = non-full.
Producers wait for full to non-full.
Producers signal = non-empty to empty.
 

So, in this case, one mutex is = likely used with with two condition = variables.

What is the = downside?
 

Condition variables are allowed to have = spurious wakeups.
This would "just" increase them. Too = much?
 

So, therefore, what would be wrong with the = following design?
 a mutex contains an event 
 and a number of = waiters, zero or non-zero 
 if a mutex is = exiting with a non-zero number of waiters, signal the = event
 

To handle Signal vs. Broadcast
method = 1:
 the number of waiters might be interlocked
 the = woken would decrement it
 if it isn't zero, signal the event = again
 

method 2:
 the number of waiters is both = an integer and a semaphore
 and the lock exiter raises the = semaphore by the the integer

 
method 3:
 it is = not an auto-reset event and there is a count
  and when the = count goes to 0, reset the event
 I think in this case you have = to maintain a "wait generation" 
 so that new = waiters don't prevent the count from ever hitting 0.
 I think = this #3 is what Java might be doing, and is described here:
http://www.cs.wu= stl.edu/~schmidt/win32-cv-1.html
 "3.3. The Generation Count = Solution"

 
also:
http://www.cs.wu= stl.edu/~schmidt/win32-cv-1.html
3.2. The SetEvent = Solution
Evaluating the SetEvent Solution
Incorrectness -- 
 

Is that = incorrect case really necessarily incorrect?
It seems unfair, since = first waiter should be first woken, but..?

 
Am I missing = something? A lot?

I don't really understand what's going on there. But I made another test which might or might not be helpful. I single-stepped in thread 1 until it blocks. We get actually no output from other threads then (though several have been started, but then thread 3 seems to be corrupt.

I just noticed that p007 seems to have been commented out in the test runs before 9/29 :-/ So Jay is probably right, and we have no reliable time frame for the bug. cd ../src/p0/p005 && cm3 -silent -DM3TESTS >I386_OPENBSD/stdout.build.raw 2>I386_OPENBSD/stderr.build.raw --- p006 --- a bit more complicated cd ../src/p0/p006 && cm3 -silent -DM3TESTS >I386_OPENBSD/stdout.build.raw 2>I386_OPENBSD/stderr.build.raw --- p008 --- thread alerts The test itself changed at that time, though.

I slightly extended the time frame to be on the safe side: cvs diff -u -r release_branch_cm3_5_8:2009-09-26 \ -r release_branch_cm3_5_8:2009-09-30 \ m3-libs/*/src m3-sys/*/src > ~/tmp/p007-diffs Jay's system is still offline.

I've attached a short paper by Andrew Birrell "Implementing Condition Variables with Semaphores" that you may find interesting / enlightening. My concern about using multiple mutex with same condition lies in the queuing operations. My recollection is that I've always associated only one mutex with a condition variable, but that you can have multiple conditions associated with the same mutex. I will go back and re-read Nelson again--its been a few years. Regards, Randy Coleburn >>> Jay K 10/18/2009 4:16 AM >>> I still have questions here. 1) Page 93 of the Nelson book: A monitor consists of some data, a mutex, and zero or more condition variables. A particular condition variable is always used in conjunction with the same mutex and its data. Doesn't this contradict the point made here? Does a condition variable always map to the same mutex or not? Or is this merely describing a typical usage pattern that is a subset of what interface Thread allows? 2) Can Wait only be satisfied by Signal/Broadcast, or also just via UnlockMutex? Depending on the answer to these questions, it seems you can largely merge mutex and condition variable. Condition variable is basically waiting for a thread to exit a mutex. Which is very very similar to LockMutex, except that it doesn't want to take the mutex in the uncontended case, it actually wants to wait for another thread to both acquire and release the mutex. I suspect I'm wrong on both of these. That condition variable really can use multiple mutexes. That exiting a mutex has no obligation to wake condition variables, though it might be in good faith to do so...er..if it is in good faith to not require programmer to use Signal/Broadcast.

The Modula-3 spec (and the current pthreads-based implementation as also the win32 implementation I expect) do allow a condition variable being mediated by different mutexes. My comment was clouded by my recollection from the pthreads spec that for pthread mutex/cv behavior for other than 1 mutex per cv is undefined. This confusion may have been the source of prior bugs in the pthreads threading implementation, but those bugs are gone now. We support the M3 spec properly.

So..one way I think about condition = variables
is that you want to be woken when someone else

You want to = know when another thread modifies the data.
(If you have a = reader/writer lock, you only want to be
woken when someone exits a = write.)
 

Now, if you consider a producer/consumer = queue.
There are two interesting occurences.
Transitions from = empty to non-empty
and transitions from full to non-full = (optionally,
if it is fixed size).
 

Consumers wait = for empty to non-empty.
Consumers signal full to = non-full.
Producers wait for full to non-full.
Producers signal = non-empty to empty.
 

So, in this case, one mutex is = likely used with with two condition = variables.
 

But, what if we take a simplifying = deoptimization and assume that a condition
variable is only ever = associated with one mutex?
Anyone existing that mutex wakes up anyone = waiting on any condition associated with it?
Like, a condition = variable I think becomes stateless and everything is

What is the = downside?
 

Condition variables are allowed to have = spurious wakeups.
This would "just" increase them. Too = much?
 

So, therefore, what would be wrong with the = following design?
 a mutex contains an event 
 and a number of = waiters, zero or non-zero 
 if a mutex is = exiting with a non-zero number of waiters, signal the = event
 

To handle Signal vs. Broadcast
method = 1:
 the number of waiters might be interlocked
 the = woken would decrement it
 if it isn't zero, signal the event = again
 

method 2:
 the number of waiters is both = an integer and a semaphore
 and the lock exiter raises the = semaphore by the the integer

 
method 3:
 it is = not an auto-reset event and there is a count
  and when the = count goes to 0, reset the event
 I think in this case you have = to maintain a "wait generation" 
 so that new = waiters don't prevent the count from ever hitting 0.

Consumers >> wait = >> for empty to non-empty.

The paper does not discuss alert but that isn't clearly a problem. Regarding a rewrite, I believe one can use the win32 alert mechanism and owner = GetCurrentThreadId, thereby allowing threads not created by m3 runtime to participate.

The GC stop-world code can simply notice they are blocked and not try to signal them, but just set their status to stopping. When the blocked thread returns from the blocking call it can notice the stopping state and transition to stopped, waiting on the stop-world semaphore. This appears to be what the Kaffe VM folks do. The unfortunate thing is that this is *totally unnecessary* on every other platform except OpenBSD, as far as I know. We do not want to add cruft to the thread primitives just to support a broken user-level threads system. Better just to revert OpenBSD to our own user-level ThreadPosix implementation until OpenBSD wakes up to the real world of SMP and multicore.

It looks as if things went OK. Ths only difference I noticed is that I ended up with a cvs/sup directory as well as a cvs/cm3/sup directory. My guess is that it's something that cvsup uses to keep track of things so I rerun cvsup to get updates efficiently. But why do I get two of them?

Might it confuse cvsup? The one on the server is just a relict, I guess. You only need the local one. CVSup keeps a checksum list there. You can delete it, but it will speed up things if it exists.

The order of two unlocks is reversed. It probably doesn't matter. He says LockMutex/UnlockMutex are just P/V. Ours is a bit different. We have queueing on our locks which appears unncessary, but is maybe with in mind an optimization mentioned but now shown by Birrel -- that of Signal with a lock held transfering a thread right to the mutex's wait list. Birrel also has one mutex per condition variable but that seems to maybe be incidental and not architectural. I believe there is much room for performance improvement here, but if it is correct, it is ok for this release. As well, I believe lock/conditionvariables can be made to work in threads not created by the Modula-3 runtime, at least with a dependency on NT4 or Win2000 (QueueUserAPC to trigger alert). (owner = GetCurrentThreadId instead of T). I put in a bunch of RTIO in Juno. Whenever it hangs, the Signal call doesn't actually occur. We have to try to figure out why. It is something in the Misc/misc calls. So ThreadWin32.m3 is fairly well vindicated (except maybe via some roundabout fashion). The heap corruption is now fairly rare in Juno. I don't know if it is consistent or not. The contents are, not sure of the address. I'll debug more. My next idea..since I think the corruption involves copying a pixmap over other data, is to alter all pixmaps to be composed of specific data, see if that occurs in the corruption, to try to confirm this part of my theory. If that holds, then the memcpys done by gc could check for the pattern (actually they could check anyway, I thought I tried that already, will try again). As well, with ThreadWin32.m3 having gotten some fixes, getting various timestamps of the source tree might be a good idea. With ThreadWin32.m3 fairly well vindicated, we might declare the quality is high enough asis. ? But I'd like to keep investigating. (Anyone else can?) The doubt imho is now more cast upon the Win32 Trestle code. We might even try Cygwin configured to use Win32 threads and X Windows and see if that has the same bug.

The pthread_suspend_all_np() function interrupts all threads except the current thread and places them in a suspended state. The pthread_resume_np() function resumes a thread suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_all_np() function resumes all threads suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_np() and pthread_resume_all_np() functions have no ef- fect on threads that have not been suspended. Suspending and resuming a thread has an effect similar to that of receiv- ing a signal, namely that resumed system calls will return an error value of EINTR. RETURN VALUES The pthread_suspend_np() and pthread_resume_np() functions fail if: [ESRCH] No thread could be found corresponding to that specified by the given thread ID.

Agreed. > The only reason to have it in the CV is to achieve the optimization, > so you know to which mutex queue we should transfer the signalled/broadcast thread. Of course. I should have realized that. Um..the data is available anyway though, isn't it? The thread had to call wait(mutex, condition) in order for signal(condition) to unlink him from the condition's waiters, the waiting thread can store the mutex in itself (he can only be waiting on one condition variable at a time) and the signaling thread can grab that. I think. In either case, I'm not too inclined to touch it for this release until we are sure there is a bug, and that looks unlikely at this point. We could try putting back your BroadcastHeap change? It also seems a little gross that the heap lock is a special case recursive mutex. It seems like we should have Mutex and RecursiveMutex, have either work with Condition, and have LockHeap/UnlockHeap/BroadcastHeap just be wrappers around that. More generally we should probably try to embelish Thread.i3 with more primitives I think. At least "interlocked" and "once", if not "event" and "semaphore". "once" could definitely see a fair amount of use. The rest maybe not, maybe they are too primitive and hard to get good use out of, hard to define portably/efficiently. Or maybe LockHeap/UnlockHeap recursive support could/should be removed and just stick with Mutex and Condition and nothing else? Well, reader/writer locks are nice. The "Little Book of Semaphores" seems to suggest ideas like "turnstile", "rendevous" and maybe others, though I'm not sure they are actually easy to think about (I don't seem able to keep up with the author :( ), and possibly a generalization of reader/writer, like an n/m/o lock where you have x classes of code and different numbers of them are allowed to have the lock. Reader/writer is 2 classes with unlimited/1 access. There is a case of read/insert/delete that can scale a bit better than reader/writer. And maybe a "thread local" mechanism? - Jay CC: m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] Juno/Thread/Win32 notes Date: Wed, 21 Oct 2009 21:56:21 -0400 On 21 Oct 2009, at 17:02, Jay K wrote: ThreadWin32.m3 almost exactly matches Birrel's design.

We have queueing on our locks which appears unncessary, but is maybe with in mind an optimization mentioned but now shown by Birrel -- that of Signal with a lock held transfering a thread right to the mutex's wait list. The queueing on mutexes does appear unnecessary, unless the optimization can be achieved. Birrel also has one mutex per condition variable but that seems to maybe be incidental and not architectural. The only reason to have it in the CV is to achieve the optimization, so you know to which mutex queue we should transfer the signalled/broadcast thread. I believe there is much room for performance improvement here, but if it is correct, it is ok for this release. As well, I believe lock/conditionvariables can be made to work in threads not created by the Modula-3 runtime, at least with a dependency on NT4 or Win2000 (QueueUserAPC to trigger alert). (owner = GetCurrentThreadId instead of T). Sure. I put in a bunch of RTIO in Juno. Whenever it hangs, the Signal call doesn't actually occur. We have to try to figure out why. It is something in the Misc/misc calls. What are the Misc/misc calls? So ThreadWin32.m3 is fairly well vindicated (except maybe via some roundabout fashion). The heap corruption is now fairly rare in Juno. I don't know if it is consistent or not. The contents are, not sure of the address. I'll debug more. My next idea..since I think the corruption involves copying a pixmap over other data, is to alter all pixmaps to be composed of specific data, see if that occurs in the corruption, to try to confirm this part of my theory. If that holds, then the memcpys done by gc could check for the pattern (actually they could check anyway, I thought I tried that already, will try again). The corruption comes outside of GC. It's just that the GC dicovers it. This should really be straightforward to catch, if you can make it occur deterministically. As well, with ThreadWin32.m3 having gotten some fixes, getting various timestamps of the source tree might be a good idea. With ThreadWin32.m3 fairly well vindicated, we might declare the quality is high enough asis. ? But I'd like to keep investigating. (Anyone else can?) The doubt imho is now more cast upon the Win32 Trestle code. We might even try Cygwin configured to use Win32 threads and X Windows and see if that has the same bug.

Not that I see. They probably don't scramble in setjmp/longjmp though?

The pthread_suspend_all_np() function interrupts all threads except the current thread and places them in a suspended state. The pthread_resume_np() function resumes a thread suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_all_np() function resumes all threads suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_np() and pthread_resume_all_np() functions have no ef- fect on threads that have not been suspended. Suspending and resuming a thread has an effect similar to that of receiv- ing a signal, namely that resumed system calls will return an error value of EINTR. RETURN VALUES The pthread_suspend_np() and pthread_resume_np() functions fail if: [ESRCH] No thread could be found corresponding to that specified by the given thread ID. The pthread_suspend_np() function fails if: [EDEADLK] Attempt to suspend the current thread. SEE ALSO pthread_cancel(3), pthreads(3) STANDARDS The pthread_suspend_np(), pthread_suspend_all_np(), pthread_resume_np() and pthread_resume_all_np() functions are non-portable and may not be supported with the above semantics on other POSIX systems.

"once" could definitely see a fair amount of use. The rest maybe not, maybe they are too primitive and hard to get good use out of, hard to define portably/efficiently. Or maybe LockHeap/UnlockHeap recursive support could/should be removed and just stick with Mutex and Condition and nothing else? Well, reader/writer locks are nice. The "Little Book of Semaphores" seems to suggest ideas like "turnstile", "rendevous" and maybe others, though I'm not sure they are actually easy to think about (I don't seem able to keep up with the author :( ), and possibly a generalization of reader/writer, like an n/m/o lock where you have x classes of code and different numbers of them are allowed to have the lock. Reader/writer is 2 classes with unlimited/1 access. There is a case of read/insert/delete that can scale a bit better than reader/writer. And maybe a "thread local" mechanism? - Jay CC: m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] Juno/Thread/Win32 notes Date: Wed, 21 Oct 2009 21:56:21 -0400 On 21 Oct 2009, at 17:02, Jay K wrote: ThreadWin32.m3 almost exactly matches Birrel's design. The order of two unlocks is reversed. It probably doesn't matter. He says LockMutex/UnlockMutex are just P/V. Ours is a bit different. We have queueing on our locks which appears unncessary, but is maybe with in mind an optimization mentioned but now shown by Birrel -- that of Signal with a lock held transfering a thread right to the mutex's wait list. The queueing on mutexes does appear unnecessary, unless the optimization can be achieved. Birrel also has one mutex per condition variable but that seems to maybe be incidental and not architectural. The only reason to have it in the CV is to achieve the optimization, so you know to which mutex queue we should transfer the signalled/broadcast thread. I believe there is much room for performance improvement here, but if it is correct, it is ok for this release. As well, I believe lock/conditionvariables can be made to work in threads not created by the Modula-3 runtime, at least with a dependency on NT4 or Win2000 (QueueUserAPC to trigger alert). (owner = GetCurrentThreadId instead of T). Sure. I put in a bunch of RTIO in Juno. Whenever it hangs, the Signal call doesn't actually occur. We have to try to figure out why. It is something in the Misc/misc calls. What are the Misc/misc calls? So ThreadWin32.m3 is fairly well vindicated (except maybe via some roundabout fashion). The heap corruption is now fairly rare in Juno. I don't know if it is consistent or not. The contents are, not sure of the address. I'll debug more. My next idea..since I think the corruption involves copying a pixmap over other data, is to alter all pixmaps to be composed of specific data, see if that occurs in the corruption, to try to confirm this part of my theory. If that holds, then the memcpys done by gc could check for the pattern (actually they could check anyway, I thought I tried that already, will try again). The corruption comes outside of GC. It's just that the GC dicovers it. This should really be straightforward to catch, if you can make it occur deterministically. As well, with ThreadWin32.m3 having gotten some fixes, getting various timestamps of the source tree might be a good idea. With ThreadWin32.m3 fairly well vindicated, we might declare the quality is high enough asis. ? But I'd like to keep investigating. (Anyone else can?) The doubt imho is now more cast upon the Win32 Trestle code. We might even try Cygwin configured to use Win32 threads and X Windows and see if that has the same bug.

You think that could be a problem? Most platforms use 8K. This used to have to relate to the hardware, when there was VM-synchronized GC, but no longer.

I mean, you know, that is the only one anyone here has expressed a recent desire to use, and used it and it was made to work. He can locally edit m3makefile. - I don't know of any significant platform without pthreads except NT and hypothetical DJGPP (Linux 2.4 mentioned below) - The following I know don't have make/get/set/swapcontext: any version of Cygwin, and I suspect not worth worrying about any version of NT, and I suspect not worth worrying about I don't think fibers are viable but maybe. Fibers don't interact propertly with any locking construct except Interlocked. e.g. critical sections nor any kernel object "work". Win7 has "user mode scheduling" that addresses problems with fibers but I think only on 64bit? any version of OpenBSD Darwin <=10.4; I synthesized them for PowerPC/10.4; you might try that (I found the PowerPC compat on x86 to be not very good though, maybe that was debugging only). - I think HP-UX manpage has strong warnings about these functions, being very version specific/fragile or something. But HP-UX has pthreads. - old Linux 2.4 still seems to be in somewhat active use, in specialized areas -- my router and a networked hard drive I have; pthreads is there I think, but not NPTL. I wonder if we should have I386_FREEBSD_USERTHREADS I386_LINUX_USERTHREADS SPARC_SOLARIS_USERTHREADS? and give them decent test/Hudson/release coverage? Maybe I386_FREEBSD4_USERTHREADS I386_LINUX24_USERTHREADS To "ghettoize" them via naming only, though they'd actually work and be tested on current systems? That is, you know, make userthreads work a bunch, be more portable, maintainable, great, then what? They still sit unused/unbuilt/untested? How to fix that? At least built/testet? Maybe just with cm3 -D thing, don't release them, just build/test them regularly? > The advantage of this move will be to eliminate a large swath of "cloned" Good! Specific questions about specific platforms ask me? You can see the answer is kind of backwards -- notice how every platform I have introduced I didn't add user threads support for. Question is only then for old/dead/unused/dormant platforms, and most of them DO have pthreads these days. I have a few machines not setup or not powered on -- Irix (32bit and 64bit in one) and AIX (32bit and 64bit in one) and HP-UX/HPPA (32bit and 64bit in one), Linux/IA64 specifically are powered off. VMS/Alpha, VMS/IA64 HP-UX/IA64, Tru64 I haven't gotten up and running yet, but I think they all support pthreads a long time now so no big worry. I also don't have have Linux/PPC64 or Darwin/PPC64 capability yet. (I think after this release Linux/IA64 should be done and will require a small change -- it has "two stacks" to scan.) > but don't have easy access to existing ABIs for other targets Please try the ssh commands I sent? That'll give you OpenBSD. FreeBSD maybe but I think it is off. I can provide more but for purposes of this line of questioning doesn't seem criticla. Birch gives you Linux/AMD64 and, in (slow/VM) a fashion NT and maybe Cygwin. - Jay From: hosking at cs.purdue.edu To: m3devel at elegosoft.com Date: Fri, 23 Oct 2009 14:43:59 -0400 Subject: [M3devel] User-level threads using makecontext/getcontext/swapcontext I have a (slightly rough) derivative version of ThreadPosix working on I386_DARWIN (implemented more along the lines of the current ThreadPThread) which abstracts all the nasty C-isms into ThreadPosixC.c.

Message-ID: I just noticed..it appears that some ports historically catch SIGBUS and call SegV, and some don't install a handler for it. e.g. it looks like the Darwin platforms do this. In my porting of the signal handling code to C, I foisted this behavior on all platforms. Reasonable? Otherwise we could put #ifdef __APPLE__ around SIGBUS in RTSignalC.c. I think it is probably ok asis, or maybe even an improvement. - Jay -------------- next part -------------- An HTML attachment was scrubbed...

Does valloc restrict you to 64K pages? On 23 Oct 2009, at 09:16, Jay K wrote: Tony, a few months ago I changed the NT pagesize to 64K, so I could simply allocate with VirtualAlloc, and not waste any. You think that could be a problem? Most platforms use 8K. This used to have to relate to the hardware, when there was VM-synchronized GC, but no longer.

In-Reply-To: References: Message-ID: full disclosure: This version has the bug where non-standalone NT apps don't do set operations correctly. (This is fixed in newer source, related to dynamically linking to data instead of the usual functions.) I'll retest with standalone. If that survives hundreds of iterations I can go forward gradually and find when things broke. - Jay From: jay.krell at cornell.edu To: hosking at cs.purdue.edu Date: Mon, 26 Oct 2009 02:45:57 +0000 CC: m3devel at elegosoft.com Subject: Re: [M3devel] Juno/Thread/Win32 notes (crashing intermittently from way back when..)

Message-ID: On Windows I use: type \cm3\bin\j.cmd @echo off setlocal set a=1 :loop echo %a% \bin\x86\cdb -g -G Juno.exe @M3no-trestle-await-delete @M3paranoidgc set /a a=a + 1 goto :loop this runs Juno in a loop, in a debugger, until it hits an access violation. It prints how many times it has run before each run. -g means go right away at the start of the process -G means go past the end of the process set /a is for "arithmetic" (expression evaluation) What is the equivalent with gdb/sh?

Hudson hasn't built anything for about a month, so there have been no check-ins to the release branch. (1) Has the OpenBSD problem been fixed or worked around? If so, what are the relevant changes that should me merged from trunk? The ChangeLog shows a lot of commits on head... (2) Is there still a problem in Windows threads? Or are we just chasing a general access violation due to an unknown reason? Again, is this ongoing or should some changes be merged for the release?

In-Reply-To: References: Message-ID: Here's a better view of the problem, again in 5.2.6. Notice 00e15888 repeating in both threads' parameters. This seems like a simple "add a lock use somewhere" problem but I have little idea of Trestle's locking protocols, apparently a complicated topic. You know, somehow redisplay/reshape need more serialization, but I don't know exactly what. The call to Capture fails with a dereference of NIL in the LOCK use.

There was really just one main problem in Win32 threads, a copy/paste error I made a few months ago. It is fixed in release. OpenBSD we know the fix but not sure we'll get to it. There are still problems with mentor and/or Juno and/or Trestle, all Windows specific. To some extent there are problems going back years, but things seem to be much worse lately.

In-Reply-To: References: <20091021200537.2rpal2av1cosc4k4@mail.elegosoft.com> Message-ID: OpenBSD user-level threading should work one way (using getcontext/ setcontext./swapcontext/makecontext if available there) or another (emulating these using setjmp/longjmp and a documented approach to synthesizing thread stacks using sigaltstack). Pthread threading is unlikely to work on OpenBSD until they fully support rthreads, but since OpenBSD pthreads are user-level we might as well use our own ThreadPosix implementation. I don't know if the old (current RC branch) ThreadPosix will work on OpenBSD or whether it would be worth moving to the much improved version I implemented this weekend which is now on trunk.

In-Reply-To: References: <20091021200537.2rpal2av1cosc4k4@mail.elegosoft.com> Message-ID: Tony, I understand "as long as OpenBSD pthreads is userthreads, we might as well use our own" but I don't understand "pthread threading is unlikely to work on OpenBSD". Shouldn't it work pretty ok actually? Except for the suspend/resume stuff? It should be easy to have OpenBSD custom stuff like Darwin has custom stuff, right? I was of the impression that the stack could merely be heap allocated, but perhaps it takes more than that? get/set/make/swapcontext are not available as far as I know on OpenBSD, but I do have them working on OpenBSD/x86 and OpenBSD/ppc (no OpenBSD/ppc currently to test on, but not a big deal to bring up it and others). Regarding Windows I did remove the idle thread cache, which is good and bad. The removal was mismotivated, and it might be a good thing, might be a bad thing. - Jay CC: wagner at elegosoft.com; m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] Fwd: Re: Status of threads for RC4?

There was really just one main problem in Win32 threads, a copy/paste error I made a few months ago. It is fixed in release. OpenBSD we know the fix but not sure we'll get to it. There are still problems with mentor and/or Juno and/or Trestle, all Windows specific. To some extent there are problems going back years, but things seem to be much worse lately.

URL: From rcoleburn at scires.com Tue Oct 27 06:10:17 2009 From: rcoleburn at scires.com (Randy Coleburn) Date: Tue, 27 Oct 2009 01:10:17 -0400 Subject: [M3devel] organization of scripts folder Message-ID: <4AE6476E.1E75.00D7.1@scires.com> I would like to better understand the rationale behind the "scripts" folder in terms of how it is organized and supposed to be used. Here is the current folder structure: scripts +---config +---doc +---examples +---iphone | \---1 +---python +---regression \---win In the past, I had put some BAT/CMD scripts in the "scripts" folder with the intent that these would be placed in the "bin" folder of the target install. Later, the other subfolders were added, including the one named "win". It seems there are perhaps multiple intentions for the scripts folder. For example, there are scripts that one would use mainly in setting up, maintaining, or administering cm3. There are other scripts that would be useful for certain target platforms as part of the installed system. There may be other scripts useful for testing. I am almost finished with testing of a new script I want to be included in the "bin" folder of the installed system on Windows platforms. This script will replace some of the old ones I have out there. It is designed to work with Win2000, WinXP, and Vista, whereas my old scripts don't work well on Vista. I also have some scripts I've built that aid in rebuilding package sets based on the PkgInfo.txt file. Before I remove my old scripts and replace them with the new ones, I thought it best for us to think about how the scripts folder should be organized. As a first cut, I propose something along the following lines: scripts +---doc = documentation for stuff in the "scripts" folder tree +---dev = scripts used for system development, maintenance, admin + +---windows = dev scripts written for Microsoft Windows (BAT, CMD) + +---posix = dev scripts written for unix shell (sh, bash, etc.) + \---python = dev scripts written in python +---install = scripts that should be put in "bin" folder of target install + +---common = scripts common to all target platforms + +---windows = BAT/CMD scripts for Microsoft Windows + +---posix = shell scripts for POSIX platforms (sh, bash, etc.) + +---python = scripts written in python (applicable to any platform with python) + \---XXX = scripts for target platform XXX (XXX is name of platform) + (assuming XXX needs something special not covered above) \---test = scripts used for regression testing +---windows = test scripts written for Microsoft Windows (BAT, CMD) +---posix = test scripts written for unix shell (sh, bash, etc.) \---python = test scripts written in python What do you think?

That would be aplus besides the bash/bat command line language scripts and others to mantain the core system by itself without CM3IDE This new category (Scripts) could help in checking the scripting facilities in CM3IDE and further enhancements in terms of components, like those you are telling, Explorer context menu integration and possible similar add ons for Mozilla family and others like email readers and web browsers developed at DEC. As the examples Category is already present in CM3IDE would be nice to put the example scripts you mention to test CM3 system scripts for bootstraping, upgrading, testing and misc. processes to aid debugging (runtime views of M3 program parameters). Whether they can run in a common web browser interface would require harder work to make it inside CM3IDE or easier in DeckScape and WebScape web browsers. Actually hard work was made by professor Tian Zhao (UW-Milwaukee) and professor Jens Parlsberg ( Purdue University) to do type inference in NP-time for no-explicit typed obliq scripts, giving us an opportunity to implement it and help the compile/run process of obliq scripts (potentially giving an ahead of time ability to check and accept or reject some scripts) and why not, write distributed platform-independent no-explicitly typed code to produce the explicitly typed and reduce runtime overhead for better performance and improved documentation of obliq and friends scripts. Thanks in advance, hope it helps and generate some further rethinking of system scripts and new ideas on quake, obliq and friends to aid the CM3 and CM3IDE scripting engine integration enhancements. ? --- El mar, 27/10/09, Randy Coleburn escribi?: De: Randy Coleburn Asunto: Re: [M3devel] organization of scripts folder Para: "" Fecha: martes, 27 octubre, 2009 10:08 I install some of my scripts.?

Asunto: Re: [M3devel] organization of scripts folder Para: "" , "Randy Coleburn" Fecha: mi?rcoles, 28 octubre, 2009 6:03 Hi Randy: I think your idea sounds great, maybe scripts package structure clean up could help to define a "category" rather than an individual package in CM3IDE as a framework for scripting with quake, obliq, visualobliq, obliq-3d and friends, but as the CM3 builder powered support for scripting of quake, obliq and friends support already present in WebScape and DeckScape web browser programs that would help to develop "addons" for CM3IDE such as allowing distributed checking of M3, obliq, etc programs with Showheap, Shownew and Showthread views allowed for each program running; a "deck" (tab) per program of a given CM3IDE server on the web client DeckScape or WebScape browser just standalone or distributed view of it, giving the system a world of tools to delevop distributed served M3, obliq, etc programs. That would be aplus besides the bash/bat command line language scripts and others to mantain the core system by itself without CM3IDE This new category (Scripts) could help in checking the scripting facilities in CM3IDE and further enhancements in terms of components, like those you are telling, Explorer context menu integration and possible similar add ons for Mozilla family and others like email readers and web browsers developed at DEC. As the examples Category is already present in CM3IDE would be nice to put the example scripts you mention to test CM3 system scripts for bootstraping, upgrading, testing and misc. processes to aid debugging (runtime views of M3 program parameters). Whether they can run in a common web browser interface would require harder work to make it inside CM3IDE or easier in DeckScape and WebScape web browsers. Actually hard work was made by professor Tian Zhao (UW-Milwaukee) and professor Jens Parlsberg ( Purdue University) to do type inference in NP-time for no-explicit typed obliq scripts, giving us an opportunity to implement it and help the compile/run process of obliq scripts (potentially giving an ahead of time ability to check and accept or reject some scripts) and why not, write distributed platform-independent no-explicitly typed code to produce the explicitly typed and reduce runtime overhead for better performance and improved documentation of obliq and friends scripts. Thanks in advance, hope it helps and generate some further rethinking of system scripts and new ideas on quake, obliq and friends to aid the CM3 and CM3IDE scripting engine integration enhancements. --- El mar, 27/10/09, Randy Coleburn escribi?: De: Randy Coleburn Asunto: Re: [M3devel] organization of scripts folder Para: "" Fecha: martes, 27 octubre, 2009 10:08 I install some of my scripts. Not sure if anyone else uses them. Nonetheless, I know that for me some of these scripts make cm3 easier to use on Windows. For example, I have scripts that: 1. Start the IDE. 2. Set up all the paths and environment variables for operating cm3 and Microsoft linker / Visual Studio at the command shell. 3. Open a cm3 command shell window in a particular folder. I've integrated this with the Explorer context menu for even greater utility. 4. Automate building of multiple packages based on the concept of a project. etc. Perhaps others would have similar scripts that should be available as part of the install. So, I'm suggesting here that we make a conscious choice on a standardized way for folks to contribute such scripts with the intent that when the installs are built that these scripts get included. End users are free to use the scripts, not use them, or even remove them after the product is installed. What do others think?

The current layout has grown and was never 'designed'. Speaking as a naive Modula 3 user and installer (well, not so naive after all these years), I found the scripts confusing. The biggest problem was to distinguish scripts that were meant to be used directly by the user and those meant to be used by other scripts. I also found that the scripts were not adequately documented -- oh, they were documented enough that once you were familiar with them, you'd know where to look for detaile you had forgotten, but not so a beginner would find it easy to figure which to use in the first place. Any documentation of reorganisation that makes these distinctions clear would be welcome. > > However, we should make sure that nothing breaks when we move scripts > around, especially for regression testing in Tinderbox and Hudson. Well, if reorganising makes it easier to get our current release through regression testing, I'm all for it. But I'd say it's really important to get a release out -- at the moment we don't really have one that's adequate for someone newly sold on the merits of Modula 3. So if there's a signoficant risk of a reorganisatin delaying things, perhaps we should hold off a bit. It seems that the current RC3 is not really adequate -- important components like m3gdb don't install properly from the binary downloads directory. And RC4 is held up on regression testing which shows significant problems in a few packages (Juno ocmes to ming). These problems appear to involve the interaction between the package, garbage colletion, multitasking, and the details of particular platforms. They are difficult problems, and it is not at all clear that they can be solved quickly, or even whether they are regressions. I'd very much like to see a RC4 that fixes the problems we've already fixed in RC3. Some of them seem to be installation issues. At least, with a current RC4, flaws and all, we would know for sure whether the installation problems in RC3 have really been fixed. > So changing things is fine as long as we consider and correct the > potential damage.

I'm seeing non-deterministic behavior on Windows XP and Vista. I am building against the head branch. On multiple runs of each build cycle, I am getting different errors. That is, sometime a package will fail to build/ship on one build cycle, then it will work on the next. I've even gone back and tried to rebuild or reship individual packages that failed and most always they will build or ship fine. For a while, I thought it might be my antivirus program. But I am getting same behavior on two different machines and each machine has a different AV program. I'll keep investigating, but something is definitely wrong. I am going to try uninstalling my AV program on one machine just to see if that makes any difference.

In-Reply-To: References: Message-ID: ok, it's not always 12 bytes in and 4b4. but anyway.. Tony does this make sense? And the atached? I seem to have it failing on an almost consistent address now. So I set write breakpoints "around" it. The object is often at 0x1cf0008. So I set write breakpoints at 0x1cf0000, 0x1cf0004, 0x1cf0008. All the writes are within RTCollector. Hm. Or so I thought. The first few are not always. Surely some of the writes are correct. And some are not? I attached a debugging log. It just goes like: bp main g ba w4 0x1cf0000 "k;g" ba w4 0x1cf0004 "k;g" ba w4 0x1cf0008 "k;g" g I also tried: ba w4 0x1cf0008 "~*k;g" etc. to get all stacks but it didn't seem useful. You know, what if two threads touch an address at about the same time? The debugger might be ambiguous. But it seems nothing else was nearby. - Jay From: jay.krell at cornell.edu To: hosking at cs.purdue.edu; m3devel at elegosoft.com Date: Sat, 31 Oct 2009 14:21:43 +0000 Subject: Re: [M3devel] debugging paranoidgc?

I'm attaching a backtrace from one crash, but I think I also am seeing deadlocks in the threading system---my application goes catatonic. Of course it *is* possible it's a bug in my application, but it works on PM3 and on CM3 on PPC_DARWIN. Finally I'm still concerned about threading performance but in the light of the bugs it's hard to say much about it yet, I think... (The program in question is a highly multithreaded stock market simulator.)

I thought this was all simple and clear by now. PTHREAD(3) FreeBSD Library Functions Manual PTHREAD(3) NAME pthread -- POSIX thread functions LIBRARY POSIX Threads Library (libpthread, -lpthread) SYNOPSIS #include DESCRIPTION POSIX threads are a set of functions that support applications with requirements for multiple flows of control, called threads, within a process. Multithreading is used to improve the performance of a program. The POSIX thread functions are summarized in this section in the follow- ing groups: o Thread Routines o Attribute Object Routines o Mutex Routines o Condition Variable Routines o Read/Write Lock Routines o Per-Thread Context Routines o Cleanup Routines Thread Routines int pthread_create(pthread_t *thread, const pthread_attr_t *attr, void *(*start_routine)(void *), void *arg) Creates a new thread of execution. int pthread_cancel(pthread_t thread) ... IMPLEMENTATION NOTES The current FreeBSD POSIX thread implementation is built in two libraries, 1:1 Threading Library (libthr, -lthr), and N:M Threading Library (libkse, -lkse). They contain both thread-safe versions of Standard C Library (libc, -lc) functions and the thread functions. Threaded applications are linked with one of these libraries. SEE ALSO pthread_atfork(3), pthread_cancel(3), pthread_cleanup_pop(3), pthread_cleanup_push(3), pthread_condattr_destroy(3), pthread_condattr_init(3), pthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_init(3), pthread_cond_signal(3), pthread_cond_timedwait(3), pthread_cond_wait(3), pthread_create(3), pthread_detach(3), pthread_equal(3), pthread_exit(3), pthread_getspecific(3), pthread_join(3), pthread_key_delete(3), pthread_kill(3), pthread_mutexattr_destroy(3), pthread_mutexattr_getprioceiling(3), pthread_mutexattr_getprotocol(3), pthread_mutexattr_gettype(3), pthread_mutexattr_init(3), pthread_mutexattr_setprioceiling(3), pthread_mutexattr_setprotocol(3), pthread_mutexattr_settype(3), pthread_mutex_destroy(3), pthread_mutex_init(3), pthread_mutex_lock(3), pthread_mutex_trylock(3), pthread_mutex_unlock(3), pthread_once(3), pthread_rwlockattr_destroy(3), pthread_rwlockattr_getpshared(3), pthread_rwlockattr_init(3), pthread_rwlockattr_setpshared(3), pthread_rwlock_destroy(3), pthread_rwlock_init(3), pthread_rwlock_rdlock(3), pthread_rwlock_unlock(3), pthread_rwlock_wrlock(3), pthread_self(3), pthread_setcancelstate(3), pthread_setcanceltype(3), pthread_setspecific(3), pthread_testcancel(3) STANDARDS The functions with the pthread_ prefix and not _np suffix or pthread_rwlock prefix conform to ISO/IEC 9945-1:1996 (``POSIX.1''). The functions with the pthread_ prefix and _np suffix are non-portable extensions to POSIX threads. The functions with the pthread_rwlock prefix are extensions created by The Open Group as part of the Version 2 of the Single UNIX Specification (``SUSv2'').

You want to know when another thread modifies the data. (If you have a reader/writer lock, you only want to be woken when someone exits a write.) Now, if you consider a producer/consumer queue. There are two interesting occurences. Transitions from empty to non-empty and transitions from full to non-full (optionally, if it is fixed size). Consumers wait for empty to non-empty. Consumers signal full to non-full. Producers wait for full to non-full. Producers signal non-empty to empty. So, in this case, one mutex is likely used with with two condition variables. But, what if we take a simplifying deoptimization and assume that a condition variable is only ever associated with one mutex? Anyone existing that mutex wakes up anyone waiting on any condition associated with it? Like, a condition variable I think becomes stateless and everything is about the mutex? What is the downside? Condition variables are allowed to have spurious wakeups. This would "just" increase them. Too much? So, therefore, what would be wrong with the following design? a mutex contains an event and a number of waiters, zero or non-zero if a mutex is exiting with a non-zero number of waiters, signal the event To handle Signal vs. Broadcast method 1: the number of waiters might be interlocked the woken would decrement it if it isn't zero, signal the event again method 2: the number of waiters is both an integer and a semaphore and the lock exiter raises the semaphore by the the integer method 3: it is not an auto-reset event and there is a count and when the count goes to 0, reset the event I think in this case you have to maintain a "wait generation" so that new waiters don't prevent the count from ever hitting 0. I think this #3 is what Java might be doing, and is described here: http://www.cs.wustl.edu/~schmidt/win32-cv-1.html "3.3. The Generation Count Solution" also: http://www.cs.wustl.edu/~schmidt/win32-cv-1.html 3.2.

Ok to make it contribute significantly to spurious wakeups? That is, I have this crazy theory...really need to come back to this fresh, try coding it, testing it..where you can implement a condition variable simply by waking everyone whenever a mutex is exited. I had this thought that what a condition variable represents is, instead of telling the kernel, here is one bit, an event, I am waiting for, instead you are telling it, hey, I have some custom code to evaluate, but it is false currently, and can only change when some exits such and such a lock, so just let me know when that lock is exited. The guy releasing the lock, or signal or broadcast..if he is signaling or broadcasting, he knows more specifically what he changed, not everything computable based on data protected by the lock, just something specific, but you can just wake everyone waiting on any of the conditions associated with the lock and it isn't maximally efficient but it should be correct. Basically, condition variable equals "wake me when someone changes some data and exits its lock". A better condition variable is that when there are multiple "conditions" in the data, the code making the change can target the wakeup better. But it isn't requires. And sometimes might not even matter much -- if in fact the ratio of locks to conditions is close to or equal to 1. - Jay CC: m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] condition variables/win32 Date: Thu, 8 Oct 2009 10:09:31 -0400 In general, it is OK in M3 to associate multiple conditions with the same mutex.

The Modula-3 spec (and the current pthreads-based implementation as also the win32 implementation I expect) do allow a condition variable being mediated by different mutexes. My comment was clouded by my recollection from the pthreads spec that for pthread mutex/cv behavior for other than 1 mutex per cv is undefined. This confusion may have been the source of prior bugs in the pthreads threading implementation, but those bugs are gone now. We support the M3 spec properly.

To handle Signal vs. Broadcast
method = 1:

 the = woken would decrement it
 if it isn't zero, signal the event = again
 

method 2:
 the number of waiters is both = an integer and a semaphore

method 3:

My concern is that if Juno is the only place where we have observed a problem, maybe the problem is with the Juno code and not with the threads implementation. That is why I was wondering if we had a non-Juno example that exhibits a problem. Having more than one exemplar may also help track down the problem. The modules I referenced in my prior message create higher-level abstractions. They are implemented using the primitives available in the language proper, no UNSAFE stuff. Of course, any efficiency improvement in the lower levels would be a benefit, and yes it is probable that recoding my abstractions at a lower level or making them features at a lower level would be more efficient. Note that I'm not suggesting that any of these abstractions be made features of the language or pushed down to the lower levels. I was just pointing out that I've got a lot of stuff that uses threading on Windows and I haven't observed that the threading implementation is broken. Perhaps I am not exercising it the same way as Juno, or perhaps Juno is doing something wrong.

So, therefore, what would be wrong with the following design? a mutex contains an event and a number of waiters, zero or non-zero if a mutex is exiting with a non-zero number of waiters, signal the event To handle Signal vs. Broadcast method 1: the number of waiters might be interlocked the woken would decrement it if it isn't zero, signal the event again method 2: the number of waiters is both an integer and a semaphore and the lock exiter raises the semaphore by the the integer method 3: it is not an auto-reset event and there is a count and when the count goes to 0, reset the event I think in this case you have to maintain a "wait generation" so that new waiters don't prevent the count from ever hitting 0. I think this #3 is what Java might be doing, and is described here: http://www.cs.wustl.edu/~schmidt/win32-cv-1.html "3.3. The Generation Count Solution" also: http://www.cs.wustl.edu/~schmidt/win32-cv-1.html 3.2. The SetEvent Solution Evaluating the SetEvent Solution Incorrectness -- Is that incorrect case really necessarily incorrect? It seems unfair, since first waiter should be first woken, but..?

I would second Randy's concern insofar as we should be able to add a test that exhibits the failure and then test any new implementation against it. At least that would be the proper way to do it. If you have a theory what breaks or where a race may be hidden, it should be possible to write a simple test, or isn't it? This again is just me with my release engineer's hat on :-) Also, if you have any tests that can be added to m3tests, please do!

Date: Thu, 15 Oct 2009 08:27:56 +0000 (GMT) Subject: [M3devel] Status of threads for RC4? In-Reply-To: Message-ID: <260188.52953.qm@web23603.mail.ird.yahoo.com> Hi all: I was merely thinking how we could mitigate the issue in threading. We could argue the current thread implementation issues on NT are worrisome but, the system performance is more important and I guess a release is waiting? for all platforms stability. I think we could make a work around to put some tests on the GUI subsystem on the test suite, using the sort of capability that Zeus Mentor Snapshot has to capture the screen shot and compare with others results with test already on: m3-ui/ui-tests m3-ui/ui/test Just getting some sort of difference between NT GUI subsystem and X implementation would allows to see where we can be missing something. Also integration on X implementation of Critical mass GUI upgrade would be highly appreciated: cm3-cvs/m3-ui/cmvbt Also I remember I saw the pm3 NT386GNU target implementation doing basic stuff with DEC SRC NT GUI, but? another doing advanced stuff with Mentor and others I think? the code you can get it by the package/src/ directories (http://www.1o0.de/wi-links/modula3/), but I?m not aware if it used the x/cygwin, I don?t think so, but even if so, would be an advance to have mentor running animation stuff until some point we could get better performance in the current NT GUI implementation (could be something in the garbage collection, Tony, as NT has its own garbage collector, has it been maintained after CM3 developed the new collector?) Another shot maybe for next release (7.0) is trying to develop tests on obliq framework and integration with pm3 documentation system, which seemed to be good. About Unix interfaces, Im thinking how to reuse the SPIN digital Unix interface so we can have a sort of a virtualization tool integrated in CM3 as a tool for deploying Unix apps on NT and getting some layers of Modula-3 runtime code based on a standarized Unix interface Sphinx.i3 (path in spin sources tree user/sphinx/src/IX86_SPIN/) something we could call "DECUnix.i3", we could also get some parts of the system running directly over Modula-3 runtime code rather than on bare Unix interfaces getting a more standarized behaviuor and maybe we could gain some knowledge to do experiments for system developers and users Thanks in advance --- El mi?, 14/10/09, Jay K escribi?: De: Jay K Asunto: Re: [M3devel] Status of threads for RC4?

This is very weird. All the threads are trying to acquire the same mutex (the global mutex in p007/src/Main.m3), but none of them is actually holding it. So, why can't one of them get it? Anyone else have any idea what's going on here?

A particular condition variable is always used in conjunction with the same mutex and its data. Doesn't this contradict the point made here? Does a condition variable always map to the same mutex or not? Or is this merely describing a typical usage pattern that is a subset of what interface Thread allows? 2) Can Wait only be satisfied by Signal/Broadcast, or also just via UnlockMutex? Depending on the answer to these questions, it seems you can largely merge mutex and condition variable. Condition variable is basically waiting for a thread to exit a mutex. Which is very very similar to LockMutex, except that it doesn't want to take the mutex in the uncontended case, it actually wants to wait for another thread to both acquire and release the mutex. I suspect I'm wrong on both of these. That condition variable really can use multiple mutexes. That exiting a mutex has no obligation to wake condition variables, though it might be in good faith to do so...er..if it is in good faith to not require programmer to use Signal/Broadcast.

The Modula-3 spec (and the current pthreads-based implementation as also the win32 implementation I expect) do allow a condition variable being mediated by different mutexes. My comment was clouded by my recollection from the pthreads spec that for pthread mutex/cv behavior for other than 1 mutex per cv is undefined. This confusion may have been the source of prior bugs in the pthreads threading implementation, but those bugs are gone now. We support the M3 spec properly.

So..one way I think about condition = variables

You want to = know when another thread modifies the data.
(If you have a = reader/writer lock, you only want to be

Now, if you consider a producer/consumer = queue.
There are two interesting occurences.
Transitions from = empty to non-empty
and transitions from full to non-full = (optionally,
if it is fixed size).
 

Consumers wait = for empty to non-empty.
Consumers signal full to = non-full.
Producers wait for full to non-full.
Producers signal = non-empty to empty.
 

So, in this case, one mutex is = likely used with with two condition = variables.

This would "just" increase them. Too = much?

 a mutex contains an event

 if a mutex is = exiting with a non-zero number of waiters, signal the = event
 

To handle Signal vs. Broadcast
method = 1:
 the number of waiters might be interlocked
 the = woken would decrement it
 if it isn't zero, signal the event = again
 

method 2:
 the number of waiters is both = an integer and a semaphore
 and the lock exiter raises the = semaphore by the the integer

 
method 3:
 it is = not an auto-reset event and there is a count
  and when the = count goes to 0, reset the event
 I think in this case you have = to maintain a "wait generation" 
 so that new = waiters don't prevent the count from ever hitting 0.

I just noticed that p007 seems to have been commented out in the test runs before 9/29 :-/ So Jay is probably right, and we have no reliable time frame for the bug. cd ../src/p0/p005 && cm3 -silent -DM3TESTS >I386_OPENBSD/stdout.build.raw 2>I386_OPENBSD/stderr.build.raw --- p006 --- a bit more complicated cd ../src/p0/p006 && cm3 -silent -DM3TESTS >I386_OPENBSD/stdout.build.raw 2>I386_OPENBSD/stderr.build.raw --- p008 --- thread alerts The test itself changed at that time, though. I'll attach the diffs nonetheless. > On 18 Oct 2009, at 21:57, Tony Hosking wrote: > >> Aha. That is helpful. I have a feeling it might be related to the >> changes I made to Thread.Fork.

I slightly extended the time frame to be on the safe side: cvs diff -u -r release_branch_cm3_5_8:2009-09-26 \ -r release_branch_cm3_5_8:2009-09-30 \ m3-libs/*/src m3-sys/*/src > ~/tmp/p007-diffs Jay's system is still offline.

I don't know where install.sh is coming from. The only thing in the repository I can find by that name is inside the copy of readline that is in gdb, and it is clearly not the script in question. I always use scripts/do-cm3-m3gdb.sh or do-cm3-.sh, with build or buildship, which runs cm3 in m3-sys/m3gdb, which uses m3-sys/m3gdb/src/m3makefile, which contains. starting at line 126: % build the exportable link and man page and export them cp_if ("gdb/gdb" & EXE, "m3gdb" & EXE) BindExport ("m3gdb" & EXE) ManPage ("m3gdb","1") Note that the compiled executable is in m3-sys/m3gdb/LINUXLIBC6/gdb/gdb, a different name than the one installed.

I've attached a short paper by Andrew Birrell "Implementing Condition Variables with Semaphores" that you may find interesting / enlightening. My concern about using multiple mutex with same condition lies in the queuing operations. My recollection is that I've always associated only one mutex with a condition variable, but that you can have multiple conditions associated with the same mutex. I will go back and re-read Nelson again--its been a few years. Regards, Randy Coleburn >>> Jay K 10/18/2009 4:16 AM >>> I still have questions here. 1) Page 93 of the Nelson book: A monitor consists of some data, a mutex, and zero or more condition variables. A particular condition variable is always used in conjunction with the same mutex and its data. Doesn't this contradict the point made here? Does a condition variable always map to the same mutex or not? Or is this merely describing a typical usage pattern that is a subset of what interface Thread allows? 2) Can Wait only be satisfied by Signal/Broadcast, or also just via UnlockMutex? Depending on the answer to these questions, it seems you can largely merge mutex and condition variable. Condition variable is basically waiting for a thread to exit a mutex. Which is very very similar to LockMutex, except that it doesn't want to take the mutex in the uncontended case, it actually wants to wait for another thread to both acquire and release the mutex. I suspect I'm wrong on both of these. That condition variable really can use multiple mutexes. That exiting a mutex has no obligation to wake condition variables, though it might be in good faith to do so...er..if it is in good faith to not require programmer to use Signal/Broadcast.

The Modula-3 spec (and the current pthreads-based implementation as also the win32 implementation I expect) do allow a condition variable being mediated by different mutexes. My comment was clouded by my recollection from the pthreads spec that for pthread mutex/cv behavior for other than 1 mutex per cv is undefined. This confusion may have been the source of prior bugs in the pthreads threading implementation, but those bugs are gone now. We support the M3 spec properly.

So..one way I think about condition = variables
is that you want to be woken when someone else

You want to = know when another thread modifies the data.
(If you have a = reader/writer lock, you only want to be
woken when someone exits a = write.)
 

Now, if you consider a producer/consumer = queue.
There are two interesting occurences.
Transitions from = empty to non-empty
and transitions from full to non-full = (optionally,
if it is fixed size).
 

Consumers wait = for empty to non-empty.
Consumers signal full to = non-full.
Producers wait for full to non-full.
Producers signal = non-empty to empty.
 

So, in this case, one mutex is = likely used with with two condition = variables.
 

But, what if we take a simplifying = deoptimization and assume that a condition
variable is only ever = associated with one mutex?
Anyone existing that mutex wakes up anyone = waiting on any condition associated with it?
Like, a condition = variable I think becomes stateless and everything is
about the = mutex?
 
 
What is the = downside?
 

Condition variables are allowed to have = spurious wakeups.
This would "just" increase them. Too = much?
 

So, therefore, what would be wrong with the = following design?
 a mutex contains an event 
 and a number of = waiters, zero or non-zero 
 if a mutex is = exiting with a non-zero number of waiters, signal the = event
 

To handle Signal vs. Broadcast
method = 1:
 the number of waiters might be interlocked
 the = woken would decrement it
 if it isn't zero, signal the event = again
 

method 2:
 the number of waiters is both = an integer and a semaphore
 and the lock exiter raises the = semaphore by the the integer

 
method 3:
 it is = not an auto-reset event and there is a count
  and when the = count goes to 0, reset the event
 I think in this case you have = to maintain a "wait generation" 
 so that new = waiters don't prevent the count from ever hitting 0.

Consumers >> wait = >> for empty to non-empty.

The paper does not discuss alert but that isn't clearly a problem. Regarding a rewrite, I believe one can use the win32 alert mechanism and owner = GetCurrentThreadId, thereby allowing threads not created by m3 runtime to participate.

The GC stop-world code can simply notice they are blocked and not try to signal them, but just set their status to stopping. When the blocked thread returns from the blocking call it can notice the stopping state and transition to stopped, waiting on the stop-world semaphore. This appears to be what the Kaffe VM folks do. The unfortunate thing is that this is *totally unnecessary* on every other platform except OpenBSD, as far as I know. We do not want to add cruft to the thread primitives just to support a broken user-level threads system. Better just to revert OpenBSD to our own user-level ThreadPosix implementation until OpenBSD wakes up to the real world of SMP and multicore.

It looks as if things went OK. Ths only difference I noticed is that I ended up with a cvs/sup directory as well as a cvs/cm3/sup directory. My guess is that it's something that cvsup uses to keep track of things so I rerun cvsup to get updates efficiently. But why do I get two of them?

Might it confuse cvsup? The one on the server is just a relict, I guess. You only need the local one. CVSup keeps a checksum list there. You can delete it, but it will speed up things if it exists.

The order of two unlocks is reversed. It probably doesn't matter. He says LockMutex/UnlockMutex are just P/V. Ours is a bit different. We have queueing on our locks which appears unncessary, but is maybe with in mind an optimization mentioned but now shown by Birrel -- that of Signal with a lock held transfering a thread right to the mutex's wait list. Birrel also has one mutex per condition variable but that seems to maybe be incidental and not architectural. I believe there is much room for performance improvement here, but if it is correct, it is ok for this release. As well, I believe lock/conditionvariables can be made to work in threads not created by the Modula-3 runtime, at least with a dependency on NT4 or Win2000 (QueueUserAPC to trigger alert). (owner = GetCurrentThreadId instead of T). I put in a bunch of RTIO in Juno. Whenever it hangs, the Signal call doesn't actually occur. We have to try to figure out why. It is something in the Misc/misc calls. So ThreadWin32.m3 is fairly well vindicated (except maybe via some roundabout fashion). The heap corruption is now fairly rare in Juno. I don't know if it is consistent or not. The contents are, not sure of the address. I'll debug more. My next idea..since I think the corruption involves copying a pixmap over other data, is to alter all pixmaps to be composed of specific data, see if that occurs in the corruption, to try to confirm this part of my theory. If that holds, then the memcpys done by gc could check for the pattern (actually they could check anyway, I thought I tried that already, will try again). As well, with ThreadWin32.m3 having gotten some fixes, getting various timestamps of the source tree might be a good idea. With ThreadWin32.m3 fairly well vindicated, we might declare the quality is high enough asis. ? But I'd like to keep investigating. (Anyone else can?) The doubt imho is now more cast upon the Win32 Trestle code. We might even try Cygwin configured to use Win32 threads and X Windows and see if that has the same bug.

The pthread_suspend_all_np() function interrupts all threads except the current thread and places them in a suspended state. The pthread_resume_np() function resumes a thread suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_all_np() function resumes all threads suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_np() and pthread_resume_all_np() functions have no ef- fect on threads that have not been suspended. Suspending and resuming a thread has an effect similar to that of receiv- ing a signal, namely that resumed system calls will return an error value of EINTR. RETURN VALUES The pthread_suspend_np() and pthread_resume_np() functions fail if: [ESRCH] No thread could be found corresponding to that specified by the given thread ID.

Agreed. > The only reason to have it in the CV is to achieve the optimization, > so you know to which mutex queue we should transfer the signalled/broadcast thread. Of course. I should have realized that. Um..the data is available anyway though, isn't it? The thread had to call wait(mutex, condition) in order for signal(condition) to unlink him from the condition's waiters, the waiting thread can store the mutex in itself (he can only be waiting on one condition variable at a time) and the signaling thread can grab that. I think. In either case, I'm not too inclined to touch it for this release until we are sure there is a bug, and that looks unlikely at this point. We could try putting back your BroadcastHeap change? It also seems a little gross that the heap lock is a special case recursive mutex. It seems like we should have Mutex and RecursiveMutex, have either work with Condition, and have LockHeap/UnlockHeap/BroadcastHeap just be wrappers around that. More generally we should probably try to embelish Thread.i3 with more primitives I think. At least "interlocked" and "once", if not "event" and "semaphore". "once" could definitely see a fair amount of use. The rest maybe not, maybe they are too primitive and hard to get good use out of, hard to define portably/efficiently. Or maybe LockHeap/UnlockHeap recursive support could/should be removed and just stick with Mutex and Condition and nothing else? Well, reader/writer locks are nice. The "Little Book of Semaphores" seems to suggest ideas like "turnstile", "rendevous" and maybe others, though I'm not sure they are actually easy to think about (I don't seem able to keep up with the author :( ), and possibly a generalization of reader/writer, like an n/m/o lock where you have x classes of code and different numbers of them are allowed to have the lock. Reader/writer is 2 classes with unlimited/1 access. There is a case of read/insert/delete that can scale a bit better than reader/writer. And maybe a "thread local" mechanism? - Jay CC: m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] Juno/Thread/Win32 notes Date: Wed, 21 Oct 2009 21:56:21 -0400 On 21 Oct 2009, at 17:02, Jay K wrote: ThreadWin32.m3 almost exactly matches Birrel's design.

We have queueing on our locks which appears unncessary, but is maybe with in mind an optimization mentioned but now shown by Birrel -- that of Signal with a lock held transfering a thread right to the mutex's wait list. The queueing on mutexes does appear unnecessary, unless the optimization can be achieved. Birrel also has one mutex per condition variable but that seems to maybe be incidental and not architectural. The only reason to have it in the CV is to achieve the optimization, so you know to which mutex queue we should transfer the signalled/broadcast thread. I believe there is much room for performance improvement here, but if it is correct, it is ok for this release. As well, I believe lock/conditionvariables can be made to work in threads not created by the Modula-3 runtime, at least with a dependency on NT4 or Win2000 (QueueUserAPC to trigger alert). (owner = GetCurrentThreadId instead of T). Sure. I put in a bunch of RTIO in Juno. Whenever it hangs, the Signal call doesn't actually occur. We have to try to figure out why. It is something in the Misc/misc calls. What are the Misc/misc calls? So ThreadWin32.m3 is fairly well vindicated (except maybe via some roundabout fashion). The heap corruption is now fairly rare in Juno. I don't know if it is consistent or not. The contents are, not sure of the address. I'll debug more. My next idea..since I think the corruption involves copying a pixmap over other data, is to alter all pixmaps to be composed of specific data, see if that occurs in the corruption, to try to confirm this part of my theory. If that holds, then the memcpys done by gc could check for the pattern (actually they could check anyway, I thought I tried that already, will try again). The corruption comes outside of GC. It's just that the GC dicovers it. This should really be straightforward to catch, if you can make it occur deterministically. As well, with ThreadWin32.m3 having gotten some fixes, getting various timestamps of the source tree might be a good idea. With ThreadWin32.m3 fairly well vindicated, we might declare the quality is high enough asis. ? But I'd like to keep investigating. (Anyone else can?) The doubt imho is now more cast upon the Win32 Trestle code. We might even try Cygwin configured to use Win32 threads and X Windows and see if that has the same bug.

Not that I see. They probably don't scramble in setjmp/longjmp though?

The pthread_suspend_all_np() function interrupts all threads except the current thread and places them in a suspended state. The pthread_resume_np() function resumes a thread suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_all_np() function resumes all threads suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_np() and pthread_resume_all_np() functions have no ef- fect on threads that have not been suspended. Suspending and resuming a thread has an effect similar to that of receiv- ing a signal, namely that resumed system calls will return an error value of EINTR. RETURN VALUES The pthread_suspend_np() and pthread_resume_np() functions fail if: [ESRCH] No thread could be found corresponding to that specified by the given thread ID. The pthread_suspend_np() function fails if: [EDEADLK] Attempt to suspend the current thread. SEE ALSO pthread_cancel(3), pthreads(3) STANDARDS The pthread_suspend_np(), pthread_suspend_all_np(), pthread_resume_np() and pthread_resume_all_np() functions are non-portable and may not be supported with the above semantics on other POSIX systems.

"once" could definitely see a fair amount of use. The rest maybe not, maybe they are too primitive and hard to get good use out of, hard to define portably/efficiently. Or maybe LockHeap/UnlockHeap recursive support could/should be removed and just stick with Mutex and Condition and nothing else? Well, reader/writer locks are nice. The "Little Book of Semaphores" seems to suggest ideas like "turnstile", "rendevous" and maybe others, though I'm not sure they are actually easy to think about (I don't seem able to keep up with the author :( ), and possibly a generalization of reader/writer, like an n/m/o lock where you have x classes of code and different numbers of them are allowed to have the lock. Reader/writer is 2 classes with unlimited/1 access. There is a case of read/insert/delete that can scale a bit better than reader/writer. And maybe a "thread local" mechanism? - Jay CC: m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] Juno/Thread/Win32 notes Date: Wed, 21 Oct 2009 21:56:21 -0400 On 21 Oct 2009, at 17:02, Jay K wrote: ThreadWin32.m3 almost exactly matches Birrel's design. The order of two unlocks is reversed. It probably doesn't matter. He says LockMutex/UnlockMutex are just P/V. Ours is a bit different. We have queueing on our locks which appears unncessary, but is maybe with in mind an optimization mentioned but now shown by Birrel -- that of Signal with a lock held transfering a thread right to the mutex's wait list. The queueing on mutexes does appear unnecessary, unless the optimization can be achieved. Birrel also has one mutex per condition variable but that seems to maybe be incidental and not architectural. The only reason to have it in the CV is to achieve the optimization, so you know to which mutex queue we should transfer the signalled/broadcast thread. I believe there is much room for performance improvement here, but if it is correct, it is ok for this release. As well, I believe lock/conditionvariables can be made to work in threads not created by the Modula-3 runtime, at least with a dependency on NT4 or Win2000 (QueueUserAPC to trigger alert). (owner = GetCurrentThreadId instead of T). Sure. I put in a bunch of RTIO in Juno. Whenever it hangs, the Signal call doesn't actually occur. We have to try to figure out why. It is something in the Misc/misc calls. What are the Misc/misc calls? So ThreadWin32.m3 is fairly well vindicated (except maybe via some roundabout fashion). The heap corruption is now fairly rare in Juno. I don't know if it is consistent or not. The contents are, not sure of the address. I'll debug more. My next idea..since I think the corruption involves copying a pixmap over other data, is to alter all pixmaps to be composed of specific data, see if that occurs in the corruption, to try to confirm this part of my theory. If that holds, then the memcpys done by gc could check for the pattern (actually they could check anyway, I thought I tried that already, will try again). The corruption comes outside of GC. It's just that the GC dicovers it. This should really be straightforward to catch, if you can make it occur deterministically. As well, with ThreadWin32.m3 having gotten some fixes, getting various timestamps of the source tree might be a good idea. With ThreadWin32.m3 fairly well vindicated, we might declare the quality is high enough asis. ? But I'd like to keep investigating. (Anyone else can?) The doubt imho is now more cast upon the Win32 Trestle code. We might even try Cygwin configured to use Win32 threads and X Windows and see if that has the same bug.

You think that could be a problem? Most platforms use 8K. This used to have to relate to the hardware, when there was VM-synchronized GC, but no longer.

I mean, you know, that is the only one anyone here has expressed a recent desire to use, and used it and it was made to work. He can locally edit m3makefile. - I don't know of any significant platform without pthreads except NT and hypothetical DJGPP (Linux 2.4 mentioned below) - The following I know don't have make/get/set/swapcontext: any version of Cygwin, and I suspect not worth worrying about any version of NT, and I suspect not worth worrying about I don't think fibers are viable but maybe. Fibers don't interact propertly with any locking construct except Interlocked. e.g. critical sections nor any kernel object "work". Win7 has "user mode scheduling" that addresses problems with fibers but I think only on 64bit? any version of OpenBSD Darwin <=10.4; I synthesized them for PowerPC/10.4; you might try that (I found the PowerPC compat on x86 to be not very good though, maybe that was debugging only). - I think HP-UX manpage has strong warnings about these functions, being very version specific/fragile or something. But HP-UX has pthreads. - old Linux 2.4 still seems to be in somewhat active use, in specialized areas -- my router and a networked hard drive I have; pthreads is there I think, but not NPTL. I wonder if we should have I386_FREEBSD_USERTHREADS I386_LINUX_USERTHREADS SPARC_SOLARIS_USERTHREADS? and give them decent test/Hudson/release coverage? Maybe I386_FREEBSD4_USERTHREADS I386_LINUX24_USERTHREADS To "ghettoize" them via naming only, though they'd actually work and be tested on current systems? That is, you know, make userthreads work a bunch, be more portable, maintainable, great, then what? They still sit unused/unbuilt/untested? How to fix that? At least built/testet? Maybe just with cm3 -D thing, don't release them, just build/test them regularly? > The advantage of this move will be to eliminate a large swath of "cloned" Good! Specific questions about specific platforms ask me? You can see the answer is kind of backwards -- notice how every platform I have introduced I didn't add user threads support for. Question is only then for old/dead/unused/dormant platforms, and most of them DO have pthreads these days. I have a few machines not setup or not powered on -- Irix (32bit and 64bit in one) and AIX (32bit and 64bit in one) and HP-UX/HPPA (32bit and 64bit in one), Linux/IA64 specifically are powered off. VMS/Alpha, VMS/IA64 HP-UX/IA64, Tru64 I haven't gotten up and running yet, but I think they all support pthreads a long time now so no big worry. I also don't have have Linux/PPC64 or Darwin/PPC64 capability yet. (I think after this release Linux/IA64 should be done and will require a small change -- it has "two stacks" to scan.) > but don't have easy access to existing ABIs for other targets Please try the ssh commands I sent? That'll give you OpenBSD. FreeBSD maybe but I think it is off. I can provide more but for purposes of this line of questioning doesn't seem criticla. Birch gives you Linux/AMD64 and, in (slow/VM) a fashion NT and maybe Cygwin. - Jay From: hosking at cs.purdue.edu To: m3devel at elegosoft.com Date: Fri, 23 Oct 2009 14:43:59 -0400 Subject: [M3devel] User-level threads using makecontext/getcontext/swapcontext I have a (slightly rough) derivative version of ThreadPosix working on I386_DARWIN (implemented more along the lines of the current ThreadPThread) which abstracts all the nasty C-isms into ThreadPosixC.c.

Message-ID: I just noticed..it appears that some ports historically catch SIGBUS and call SegV, and some don't install a handler for it. e.g. it looks like the Darwin platforms do this. In my porting of the signal handling code to C, I foisted this behavior on all platforms. Reasonable? Otherwise we could put #ifdef __APPLE__ around SIGBUS in RTSignalC.c. I think it is probably ok asis, or maybe even an improvement. - Jay -------------- next part -------------- An HTML attachment was scrubbed...

Does valloc restrict you to 64K pages? On 23 Oct 2009, at 09:16, Jay K wrote: Tony, a few months ago I changed the NT pagesize to 64K, so I could simply allocate with VirtualAlloc, and not waste any. You think that could be a problem? Most platforms use 8K. This used to have to relate to the hardware, when there was VM-synchronized GC, but no longer.

In-Reply-To: References: Message-ID: full disclosure: This version has the bug where non-standalone NT apps don't do set operations correctly. (This is fixed in newer source, related to dynamically linking to data instead of the usual functions.) I'll retest with standalone. If that survives hundreds of iterations I can go forward gradually and find when things broke. - Jay From: jay.krell at cornell.edu To: hosking at cs.purdue.edu Date: Mon, 26 Oct 2009 02:45:57 +0000 CC: m3devel at elegosoft.com Subject: Re: [M3devel] Juno/Thread/Win32 notes (crashing intermittently from way back when..)

Message-ID: On Windows I use: type \cm3\bin\j.cmd @echo off setlocal set a=1 :loop echo %a% \bin\x86\cdb -g -G Juno.exe @M3no-trestle-await-delete @M3paranoidgc set /a a=a + 1 goto :loop this runs Juno in a loop, in a debugger, until it hits an access violation. It prints how many times it has run before each run. -g means go right away at the start of the process -G means go past the end of the process set /a is for "arithmetic" (expression evaluation) What is the equivalent with gdb/sh?

Hudson hasn't built anything for about a month, so there have been no check-ins to the release branch. (1) Has the OpenBSD problem been fixed or worked around? If so, what are the relevant changes that should me merged from trunk? The ChangeLog shows a lot of commits on head... (2) Is there still a problem in Windows threads? Or are we just chasing a general access violation due to an unknown reason? Again, is this ongoing or should some changes be merged for the release?

In-Reply-To: References: Message-ID: Here's a better view of the problem, again in 5.2.6. Notice 00e15888 repeating in both threads' parameters. This seems like a simple "add a lock use somewhere" problem but I have little idea of Trestle's locking protocols, apparently a complicated topic. You know, somehow redisplay/reshape need more serialization, but I don't know exactly what. The call to Capture fails with a dereference of NIL in the LOCK use.

There was really just one main problem in Win32 threads, a copy/paste error I made a few months ago. It is fixed in release. OpenBSD we know the fix but not sure we'll get to it. There are still problems with mentor and/or Juno and/or Trestle, all Windows specific. To some extent there are problems going back years, but things seem to be much worse lately.

In-Reply-To: References: <20091021200537.2rpal2av1cosc4k4@mail.elegosoft.com> Message-ID: OpenBSD user-level threading should work one way (using getcontext/ setcontext./swapcontext/makecontext if available there) or another (emulating these using setjmp/longjmp and a documented approach to synthesizing thread stacks using sigaltstack). Pthread threading is unlikely to work on OpenBSD until they fully support rthreads, but since OpenBSD pthreads are user-level we might as well use our own ThreadPosix implementation. I don't know if the old (current RC branch) ThreadPosix will work on OpenBSD or whether it would be worth moving to the much improved version I implemented this weekend which is now on trunk.

In-Reply-To: References: <20091021200537.2rpal2av1cosc4k4@mail.elegosoft.com> Message-ID: Tony, I understand "as long as OpenBSD pthreads is userthreads, we might as well use our own" but I don't understand "pthread threading is unlikely to work on OpenBSD". Shouldn't it work pretty ok actually? Except for the suspend/resume stuff? It should be easy to have OpenBSD custom stuff like Darwin has custom stuff, right? I was of the impression that the stack could merely be heap allocated, but perhaps it takes more than that? get/set/make/swapcontext are not available as far as I know on OpenBSD, but I do have them working on OpenBSD/x86 and OpenBSD/ppc (no OpenBSD/ppc currently to test on, but not a big deal to bring up it and others). Regarding Windows I did remove the idle thread cache, which is good and bad. The removal was mismotivated, and it might be a good thing, might be a bad thing. - Jay CC: wagner at elegosoft.com; m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] Fwd: Re: Status of threads for RC4?

There was really just one main problem in Win32 threads, a copy/paste error I made a few months ago. It is fixed in release. OpenBSD we know the fix but not sure we'll get to it. There are still problems with mentor and/or Juno and/or Trestle, all Windows specific. To some extent there are problems going back years, but things seem to be much worse lately.

URL: From rcoleburn at scires.com Tue Oct 27 06:10:17 2009 From: rcoleburn at scires.com (Randy Coleburn) Date: Tue, 27 Oct 2009 01:10:17 -0400 Subject: [M3devel] organization of scripts folder Message-ID: <4AE6476E.1E75.00D7.1@scires.com> I would like to better understand the rationale behind the "scripts" folder in terms of how it is organized and supposed to be used. Here is the current folder structure: scripts +---config +---doc +---examples +---iphone | \---1 +---python +---regression \---win In the past, I had put some BAT/CMD scripts in the "scripts" folder with the intent that these would be placed in the "bin" folder of the target install. Later, the other subfolders were added, including the one named "win". It seems there are perhaps multiple intentions for the scripts folder. For example, there are scripts that one would use mainly in setting up, maintaining, or administering cm3. There are other scripts that would be useful for certain target platforms as part of the installed system. There may be other scripts useful for testing. I am almost finished with testing of a new script I want to be included in the "bin" folder of the installed system on Windows platforms. This script will replace some of the old ones I have out there. It is designed to work with Win2000, WinXP, and Vista, whereas my old scripts don't work well on Vista. I also have some scripts I've built that aid in rebuilding package sets based on the PkgInfo.txt file. Before I remove my old scripts and replace them with the new ones, I thought it best for us to think about how the scripts folder should be organized. As a first cut, I propose something along the following lines: scripts +---doc = documentation for stuff in the "scripts" folder tree +---dev = scripts used for system development, maintenance, admin + +---windows = dev scripts written for Microsoft Windows (BAT, CMD) + +---posix = dev scripts written for unix shell (sh, bash, etc.) + \---python = dev scripts written in python +---install = scripts that should be put in "bin" folder of target install + +---common = scripts common to all target platforms + +---windows = BAT/CMD scripts for Microsoft Windows + +---posix = shell scripts for POSIX platforms (sh, bash, etc.) + +---python = scripts written in python (applicable to any platform with python) + \---XXX = scripts for target platform XXX (XXX is name of platform) + (assuming XXX needs something special not covered above) \---test = scripts used for regression testing +---windows = test scripts written for Microsoft Windows (BAT, CMD) +---posix = test scripts written for unix shell (sh, bash, etc.) \---python = test scripts written in python What do you think?

That would be aplus besides the bash/bat command line language scripts and others to mantain the core system by itself without CM3IDE This new category (Scripts) could help in checking the scripting facilities in CM3IDE and further enhancements in terms of components, like those you are telling, Explorer context menu integration and possible similar add ons for Mozilla family and others like email readers and web browsers developed at DEC. As the examples Category is already present in CM3IDE would be nice to put the example scripts you mention to test CM3 system scripts for bootstraping, upgrading, testing and misc. processes to aid debugging (runtime views of M3 program parameters). Whether they can run in a common web browser interface would require harder work to make it inside CM3IDE or easier in DeckScape and WebScape web browsers. Actually hard work was made by professor Tian Zhao (UW-Milwaukee) and professor Jens Parlsberg ( Purdue University) to do type inference in NP-time for no-explicit typed obliq scripts, giving us an opportunity to implement it and help the compile/run process of obliq scripts (potentially giving an ahead of time ability to check and accept or reject some scripts) and why not, write distributed platform-independent no-explicitly typed code to produce the explicitly typed and reduce runtime overhead for better performance and improved documentation of obliq and friends scripts. Thanks in advance, hope it helps and generate some further rethinking of system scripts and new ideas on quake, obliq and friends to aid the CM3 and CM3IDE scripting engine integration enhancements. ? --- El mar, 27/10/09, Randy Coleburn escribi?: De: Randy Coleburn Asunto: Re: [M3devel] organization of scripts folder Para: "" Fecha: martes, 27 octubre, 2009 10:08 I install some of my scripts.?

Asunto: Re: [M3devel] organization of scripts folder Para: "" , "Randy Coleburn" Fecha: mi?rcoles, 28 octubre, 2009 6:03 Hi Randy: I think your idea sounds great, maybe scripts package structure clean up could help to define a "category" rather than an individual package in CM3IDE as a framework for scripting with quake, obliq, visualobliq, obliq-3d and friends, but as the CM3 builder powered support for scripting of quake, obliq and friends support already present in WebScape and DeckScape web browser programs that would help to develop "addons" for CM3IDE such as allowing distributed checking of M3, obliq, etc programs with Showheap, Shownew and Showthread views allowed for each program running; a "deck" (tab) per program of a given CM3IDE server on the web client DeckScape or WebScape browser just standalone or distributed view of it, giving the system a world of tools to delevop distributed served M3, obliq, etc programs. That would be aplus besides the bash/bat command line language scripts and others to mantain the core system by itself without CM3IDE This new category (Scripts) could help in checking the scripting facilities in CM3IDE and further enhancements in terms of components, like those you are telling, Explorer context menu integration and possible similar add ons for Mozilla family and others like email readers and web browsers developed at DEC. As the examples Category is already present in CM3IDE would be nice to put the example scripts you mention to test CM3 system scripts for bootstraping, upgrading, testing and misc. processes to aid debugging (runtime views of M3 program parameters). Whether they can run in a common web browser interface would require harder work to make it inside CM3IDE or easier in DeckScape and WebScape web browsers. Actually hard work was made by professor Tian Zhao (UW-Milwaukee) and professor Jens Parlsberg ( Purdue University) to do type inference in NP-time for no-explicit typed obliq scripts, giving us an opportunity to implement it and help the compile/run process of obliq scripts (potentially giving an ahead of time ability to check and accept or reject some scripts) and why not, write distributed platform-independent no-explicitly typed code to produce the explicitly typed and reduce runtime overhead for better performance and improved documentation of obliq and friends scripts. Thanks in advance, hope it helps and generate some further rethinking of system scripts and new ideas on quake, obliq and friends to aid the CM3 and CM3IDE scripting engine integration enhancements. --- El mar, 27/10/09, Randy Coleburn escribi?: De: Randy Coleburn Asunto: Re: [M3devel] organization of scripts folder Para: "" Fecha: martes, 27 octubre, 2009 10:08 I install some of my scripts. Not sure if anyone else uses them. Nonetheless, I know that for me some of these scripts make cm3 easier to use on Windows. For example, I have scripts that: 1. Start the IDE. 2. Set up all the paths and environment variables for operating cm3 and Microsoft linker / Visual Studio at the command shell. 3. Open a cm3 command shell window in a particular folder. I've integrated this with the Explorer context menu for even greater utility. 4. Automate building of multiple packages based on the concept of a project. etc. Perhaps others would have similar scripts that should be available as part of the install. So, I'm suggesting here that we make a conscious choice on a standardized way for folks to contribute such scripts with the intent that when the installs are built that these scripts get included. End users are free to use the scripts, not use them, or even remove them after the product is installed. What do others think?

The current layout has grown and was never 'designed'. Speaking as a naive Modula 3 user and installer (well, not so naive after all these years), I found the scripts confusing. The biggest problem was to distinguish scripts that were meant to be used directly by the user and those meant to be used by other scripts. I also found that the scripts were not adequately documented -- oh, they were documented enough that once you were familiar with them, you'd know where to look for detaile you had forgotten, but not so a beginner would find it easy to figure which to use in the first place. Any documentation of reorganisation that makes these distinctions clear would be welcome. > > However, we should make sure that nothing breaks when we move scripts > around, especially for regression testing in Tinderbox and Hudson. Well, if reorganising makes it easier to get our current release through regression testing, I'm all for it. But I'd say it's really important to get a release out -- at the moment we don't really have one that's adequate for someone newly sold on the merits of Modula 3. So if there's a signoficant risk of a reorganisatin delaying things, perhaps we should hold off a bit. It seems that the current RC3 is not really adequate -- important components like m3gdb don't install properly from the binary downloads directory. And RC4 is held up on regression testing which shows significant problems in a few packages (Juno ocmes to ming). These problems appear to involve the interaction between the package, garbage colletion, multitasking, and the details of particular platforms. They are difficult problems, and it is not at all clear that they can be solved quickly, or even whether they are regressions. I'd very much like to see a RC4 that fixes the problems we've already fixed in RC3. Some of them seem to be installation issues. At least, with a current RC4, flaws and all, we would know for sure whether the installation problems in RC3 have really been fixed. > So changing things is fine as long as we consider and correct the > potential damage.

I'm seeing non-deterministic behavior on Windows XP and Vista. I am building against the head branch. On multiple runs of each build cycle, I am getting different errors. That is, sometime a package will fail to build/ship on one build cycle, then it will work on the next. I've even gone back and tried to rebuild or reship individual packages that failed and most always they will build or ship fine. For a while, I thought it might be my antivirus program. But I am getting same behavior on two different machines and each machine has a different AV program. I'll keep investigating, but something is definitely wrong. I am going to try uninstalling my AV program on one machine just to see if that makes any difference.

In-Reply-To: References: Message-ID: ok, it's not always 12 bytes in and 4b4. but anyway.. Tony does this make sense? And the atached? I seem to have it failing on an almost consistent address now. So I set write breakpoints "around" it. The object is often at 0x1cf0008. So I set write breakpoints at 0x1cf0000, 0x1cf0004, 0x1cf0008. All the writes are within RTCollector. Hm. Or so I thought. The first few are not always. Surely some of the writes are correct. And some are not? I attached a debugging log. It just goes like: bp main g ba w4 0x1cf0000 "k;g" ba w4 0x1cf0004 "k;g" ba w4 0x1cf0008 "k;g" g I also tried: ba w4 0x1cf0008 "~*k;g" etc. to get all stacks but it didn't seem useful. You know, what if two threads touch an address at about the same time? The debugger might be ambiguous. But it seems nothing else was nearby. - Jay From: jay.krell at cornell.edu To: hosking at cs.purdue.edu; m3devel at elegosoft.com Date: Sat, 31 Oct 2009 14:21:43 +0000 Subject: Re: [M3devel] debugging paranoidgc?

I'm attaching a backtrace from one crash, but I think I also am seeing deadlocks in the threading system---my application goes catatonic. Of course it *is* possible it's a bug in my application, but it works on PM3 and on CM3 on PPC_DARWIN. Finally I'm still concerned about threading performance but in the light of the bugs it's hard to say much about it yet, I think... (The program in question is a highly multithreaded stock market simulator.)

PTHREAD(3) FreeBSD Library Functions Manual PTHREAD(3) NAME pthread -- POSIX thread functions LIBRARY POSIX Threads Library (libpthread, -lpthread) SYNOPSIS #include DESCRIPTION POSIX threads are a set of functions that support applications with requirements for multiple flows of control, called threads, within a process. Multithreading is used to improve the performance of a program. The POSIX thread functions are summarized in this section in the follow- ing groups: o Thread Routines o Attribute Object Routines o Mutex Routines o Condition Variable Routines o Read/Write Lock Routines o Per-Thread Context Routines o Cleanup Routines Thread Routines int pthread_create(pthread_t *thread, const pthread_attr_t *attr, void *(*start_routine)(void *), void *arg) Creates a new thread of execution. int pthread_cancel(pthread_t thread) ... IMPLEMENTATION NOTES The current FreeBSD POSIX thread implementation is built in two libraries, 1:1 Threading Library (libthr, -lthr), and N:M Threading Library (libkse, -lkse). They contain both thread-safe versions of Standard C Library (libc, -lc) functions and the thread functions. Threaded applications are linked with one of these libraries. SEE ALSO pthread_atfork(3), pthread_cancel(3), pthread_cleanup_pop(3), pthread_cleanup_push(3), pthread_condattr_destroy(3), pthread_condattr_init(3), pthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_init(3), pthread_cond_signal(3), pthread_cond_timedwait(3), pthread_cond_wait(3), pthread_create(3), pthread_detach(3), pthread_equal(3), pthread_exit(3), pthread_getspecific(3), pthread_join(3), pthread_key_delete(3), pthread_kill(3), pthread_mutexattr_destroy(3), pthread_mutexattr_getprioceiling(3), pthread_mutexattr_getprotocol(3), pthread_mutexattr_gettype(3), pthread_mutexattr_init(3), pthread_mutexattr_setprioceiling(3), pthread_mutexattr_setprotocol(3), pthread_mutexattr_settype(3), pthread_mutex_destroy(3), pthread_mutex_init(3), pthread_mutex_lock(3), pthread_mutex_trylock(3), pthread_mutex_unlock(3), pthread_once(3), pthread_rwlockattr_destroy(3), pthread_rwlockattr_getpshared(3), pthread_rwlockattr_init(3), pthread_rwlockattr_setpshared(3), pthread_rwlock_destroy(3), pthread_rwlock_init(3), pthread_rwlock_rdlock(3), pthread_rwlock_unlock(3), pthread_rwlock_wrlock(3), pthread_self(3), pthread_setcancelstate(3), pthread_setcanceltype(3), pthread_setspecific(3), pthread_testcancel(3) STANDARDS The functions with the pthread_ prefix and not _np suffix or pthread_rwlock prefix conform to ISO/IEC 9945-1:1996 (``POSIX.1''). The functions with the pthread_ prefix and _np suffix are non-portable extensions to POSIX threads. The functions with the pthread_rwlock prefix are extensions created by The Open Group as part of the Version 2 of the Single UNIX Specification (``SUSv2'').

You want to know when another thread modifies the data. (If you have a reader/writer lock, you only want to be woken when someone exits a write.) Now, if you consider a producer/consumer queue. There are two interesting occurences. Transitions from empty to non-empty and transitions from full to non-full (optionally, if it is fixed size). Consumers wait for empty to non-empty. Consumers signal full to non-full. Producers wait for full to non-full. Producers signal non-empty to empty. So, in this case, one mutex is likely used with with two condition variables. But, what if we take a simplifying deoptimization and assume that a condition variable is only ever associated with one mutex? Anyone existing that mutex wakes up anyone waiting on any condition associated with it? Like, a condition variable I think becomes stateless and everything is about the mutex? What is the downside? Condition variables are allowed to have spurious wakeups. This would "just" increase them. Too much? So, therefore, what would be wrong with the following design? a mutex contains an event and a number of waiters, zero or non-zero if a mutex is exiting with a non-zero number of waiters, signal the event To handle Signal vs. Broadcast method 1: the number of waiters might be interlocked the woken would decrement it if it isn't zero, signal the event again method 2: the number of waiters is both an integer and a semaphore and the lock exiter raises the semaphore by the the integer method 3: it is not an auto-reset event and there is a count and when the count goes to 0, reset the event I think in this case you have to maintain a "wait generation" so that new waiters don't prevent the count from ever hitting 0. I think this #3 is what Java might be doing, and is described here: http://www.cs.wustl.edu/~schmidt/win32-cv-1.html "3.3. The Generation Count Solution" also: http://www.cs.wustl.edu/~schmidt/win32-cv-1.html 3.2.

Ok to make it contribute significantly to spurious wakeups? That is, I have this crazy theory...really need to come back to this fresh, try coding it, testing it..where you can implement a condition variable simply by waking everyone whenever a mutex is exited. I had this thought that what a condition variable represents is, instead of telling the kernel, here is one bit, an event, I am waiting for, instead you are telling it, hey, I have some custom code to evaluate, but it is false currently, and can only change when some exits such and such a lock, so just let me know when that lock is exited. The guy releasing the lock, or signal or broadcast..if he is signaling or broadcasting, he knows more specifically what he changed, not everything computable based on data protected by the lock, just something specific, but you can just wake everyone waiting on any of the conditions associated with the lock and it isn't maximally efficient but it should be correct. Basically, condition variable equals "wake me when someone changes some data and exits its lock". A better condition variable is that when there are multiple "conditions" in the data, the code making the change can target the wakeup better. But it isn't requires. And sometimes might not even matter much -- if in fact the ratio of locks to conditions is close to or equal to 1. - Jay CC: m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] condition variables/win32 Date: Thu, 8 Oct 2009 10:09:31 -0400 In general, it is OK in M3 to associate multiple conditions with the same mutex.

The Modula-3 spec (and the current pthreads-based implementation as also the win32 implementation I expect) do allow a condition variable being mediated by different mutexes. My comment was clouded by my recollection from the pthreads spec that for pthread mutex/cv behavior for other than 1 mutex per cv is undefined. This confusion may have been the source of prior bugs in the pthreads threading implementation, but those bugs are gone now. We support the M3 spec properly.

You want to = know when another thread modifies the data.
(If you have a = reader/writer lock, you only want to be

Now, if you consider a producer/consumer = queue.
There are two interesting occurences.
Transitions from = empty to non-empty

if it is fixed size).
 

Consumers wait = for empty to non-empty.
Consumers signal full to = non-full.
Producers wait for full to non-full.
Producers signal = non-empty to empty.
 

So, in this case, one mutex is = likely used with with two condition = variables.
 

But, what if we take a simplifying = deoptimization and assume that a condition

Anyone existing that mutex wakes up anyone = waiting on any condition associated with it?
Like, a condition = variable I think becomes stateless and everything is

What is the = downside?
 

Condition variables are allowed to have = spurious wakeups.
This would "just" increase them. Too = much?
 

So, therefore, what would be wrong with the = following design?
 a mutex contains an event

 if a mutex is = exiting with a non-zero number of waiters, signal the = event
 

To handle Signal vs. Broadcast
method = 1:
 the number of waiters might be interlocked
 the = woken would decrement it
 if it isn't zero, signal the event = again
 

method 2:
 the number of waiters is both = an integer and a semaphore
 and the lock exiter raises the = semaphore by the the integer

 
method 3:
 it is = not an auto-reset event and there is a count
  and when the = count goes to 0, reset the event
 I think in this case you have = to maintain a "wait generation" 
 so that new = waiters don't prevent the count from ever hitting 0.

I would second Randy's concern insofar as we should be able to add a test that exhibits the failure and then test any new implementation against it. At least that would be the proper way to do it.

Date: Thu, 15 Oct 2009 08:27:56 +0000 (GMT) Subject: [M3devel] Status of threads for RC4? In-Reply-To: Message-ID: <260188.52953.qm@web23603.mail.ird.yahoo.com> Hi all: I was merely thinking how we could mitigate the issue in threading. We could argue the current thread implementation issues on NT are worrisome but, the system performance is more important and I guess a release is waiting? for all platforms stability. I think we could make a work around to put some tests on the GUI subsystem on the test suite, using the sort of capability that Zeus Mentor Snapshot has to capture the screen shot and compare with others results with test already on: m3-ui/ui-tests m3-ui/ui/test Just getting some sort of difference between NT GUI subsystem and X implementation would allows to see where we can be missing something. Also integration on X implementation of Critical mass GUI upgrade would be highly appreciated: cm3-cvs/m3-ui/cmvbt Also I remember I saw the pm3 NT386GNU target implementation doing basic stuff with DEC SRC NT GUI, but? another doing advanced stuff with Mentor and others I think? the code you can get it by the package/src/ directories (http://www.1o0.de/wi-links/modula3/), but I?m not aware if it used the x/cygwin, I don?t think so, but even if so, would be an advance to have mentor running animation stuff until some point we could get better performance in the current NT GUI implementation (could be something in the garbage collection, Tony, as NT has its own garbage collector, has it been maintained after CM3 developed the new collector?) Another shot maybe for next release (7.0) is trying to develop tests on obliq framework and integration with pm3 documentation system, which seemed to be good. About Unix interfaces, Im thinking how to reuse the SPIN digital Unix interface so we can have a sort of a virtualization tool integrated in CM3 as a tool for deploying Unix apps on NT and getting some layers of Modula-3 runtime code based on a standarized Unix interface Sphinx.i3 (path in spin sources tree user/sphinx/src/IX86_SPIN/) something we could call "DECUnix.i3", we could also get some parts of the system running directly over Modula-3 runtime code rather than on bare Unix interfaces getting a more standarized behaviuor and maybe we could gain some knowledge to do experiments for system developers and users Thanks in advance --- El mi?, 14/10/09, Jay K escribi?: De: Jay K Asunto: Re: [M3devel] Status of threads for RC4?

This is very weird. All the threads are trying to acquire the same mutex (the global mutex in p007/src/Main.m3), but none of them is actually holding it. So, why can't one of them get it? Anyone else have any idea what's going on here?

A particular condition variable is always used in conjunction with the same mutex and its data. Doesn't this contradict the point made here? Does a condition variable always map to the same mutex or not? Or is this merely describing a typical usage pattern that is a subset of what interface Thread allows? 2) Can Wait only be satisfied by Signal/Broadcast, or also just via UnlockMutex? Depending on the answer to these questions, it seems you can largely merge mutex and condition variable. Condition variable is basically waiting for a thread to exit a mutex. Which is very very similar to LockMutex, except that it doesn't want to take the mutex in the uncontended case, it actually wants to wait for another thread to both acquire and release the mutex. I suspect I'm wrong on both of these. That condition variable really can use multiple mutexes. That exiting a mutex has no obligation to wake condition variables, though it might be in good faith to do so...er..if it is in good faith to not require programmer to use Signal/Broadcast.

The Modula-3 spec (and the current pthreads-based implementation as also the win32 implementation I expect) do allow a condition variable being mediated by different mutexes. My comment was clouded by my recollection from the pthreads spec that for pthread mutex/cv behavior for other than 1 mutex per cv is undefined. This confusion may have been the source of prior bugs in the pthreads threading implementation, but those bugs are gone now. We support the M3 spec properly.

So..one way I think about condition = variables

You want to = know when another thread modifies the data.
(If you have a = reader/writer lock, you only want to be

Now, if you consider a producer/consumer = queue.
There are two interesting occurences.
Transitions from = empty to non-empty
and transitions from full to non-full = (optionally,
if it is fixed size).
 

Consumers wait = for empty to non-empty.
Consumers signal full to = non-full.
Producers wait for full to non-full.
Producers signal = non-empty to empty.
 

So, in this case, one mutex is = likely used with with two condition = variables.
 

But, what if we take a simplifying = deoptimization and assume that a condition

What is the = downside?
 

Condition variables are allowed to have = spurious wakeups.
This would "just" increase them. Too = much?
 

So, therefore, what would be wrong with the = following design?
 a mutex contains an event 
 and a number of = waiters, zero or non-zero 
 if a mutex is = exiting with a non-zero number of waiters, signal the = event
 

To handle Signal vs. Broadcast
method = 1:
 the number of waiters might be interlocked
 the = woken would decrement it
 if it isn't zero, signal the event = again
 

method 2:
 the number of waiters is both = an integer and a semaphore
 and the lock exiter raises the = semaphore by the the integer

 
method 3:
 it is = not an auto-reset event and there is a count
  and when the = count goes to 0, reset the event
 I think in this case you have = to maintain a "wait generation" 
 so that new = waiters don't prevent the count from ever hitting 0.

I just noticed that p007 seems to have been commented out in the test runs before 9/29 :-/ So Jay is probably right, and we have no reliable time frame for the bug. cd ../src/p0/p005 && cm3 -silent -DM3TESTS >I386_OPENBSD/stdout.build.raw 2>I386_OPENBSD/stderr.build.raw --- p006 --- a bit more complicated cd ../src/p0/p006 && cm3 -silent -DM3TESTS >I386_OPENBSD/stdout.build.raw 2>I386_OPENBSD/stderr.build.raw --- p008 --- thread alerts The test itself changed at that time, though.

I don't know where install.sh is coming from. The only thing in the repository I can find by that name is inside the copy of readline that is in gdb, and it is clearly not the script in question. I always use scripts/do-cm3-m3gdb.sh or do-cm3-.sh, with build or buildship, which runs cm3 in m3-sys/m3gdb, which uses m3-sys/m3gdb/src/m3makefile, which contains. starting at line 126: % build the exportable link and man page and export them cp_if ("gdb/gdb" & EXE, "m3gdb" & EXE) BindExport ("m3gdb" & EXE) ManPage ("m3gdb","1") Note that the compiled executable is in m3-sys/m3gdb/LINUXLIBC6/gdb/gdb, a different name than the one installed. This is no doubt a leftover from m3gdb's being derived from gdb. The line 127 above looks like it takes care of the rename. For me, both "do-cm3-m3gdb ship" (in scripts) and the cm3 -ship command it executes (in m3-sys/m3gdb) install a copy in /usr/local/cm3/bin, as expected.

I've attached a short paper by Andrew Birrell "Implementing Condition Variables with Semaphores" that you may find interesting / enlightening. My concern about using multiple mutex with same condition lies in the queuing operations. My recollection is that I've always associated only one mutex with a condition variable, but that you can have multiple conditions associated with the same mutex. I will go back and re-read Nelson again--its been a few years. Regards, Randy Coleburn >>> Jay K 10/18/2009 4:16 AM >>> I still have questions here. 1) Page 93 of the Nelson book: A monitor consists of some data, a mutex, and zero or more condition variables. A particular condition variable is always used in conjunction with the same mutex and its data. Doesn't this contradict the point made here? Does a condition variable always map to the same mutex or not? Or is this merely describing a typical usage pattern that is a subset of what interface Thread allows? 2) Can Wait only be satisfied by Signal/Broadcast, or also just via UnlockMutex? Depending on the answer to these questions, it seems you can largely merge mutex and condition variable. Condition variable is basically waiting for a thread to exit a mutex. Which is very very similar to LockMutex, except that it doesn't want to take the mutex in the uncontended case, it actually wants to wait for another thread to both acquire and release the mutex. I suspect I'm wrong on both of these. That condition variable really can use multiple mutexes. That exiting a mutex has no obligation to wake condition variables, though it might be in good faith to do so...er..if it is in good faith to not require programmer to use Signal/Broadcast.

The Modula-3 spec (and the current pthreads-based implementation as also the win32 implementation I expect) do allow a condition variable being mediated by different mutexes. My comment was clouded by my recollection from the pthreads spec that for pthread mutex/cv behavior for other than 1 mutex per cv is undefined. This confusion may have been the source of prior bugs in the pthreads threading implementation, but those bugs are gone now. We support the M3 spec properly.

So..one way I think about condition = variables
is that you want to be woken when someone else

You want to = know when another thread modifies the data.
(If you have a = reader/writer lock, you only want to be
woken when someone exits a = write.)
 

Now, if you consider a producer/consumer = queue.
There are two interesting occurences.
Transitions from = empty to non-empty
and transitions from full to non-full = (optionally,
if it is fixed size).
 

Consumers wait = for empty to non-empty.
Consumers signal full to = non-full.
Producers wait for full to non-full.
Producers signal = non-empty to empty.
 

So, in this case, one mutex is = likely used with with two condition = variables.
 

But, what if we take a simplifying = deoptimization and assume that a condition
variable is only ever = associated with one mutex?
Anyone existing that mutex wakes up anyone = waiting on any condition associated with it?
Like, a condition = variable I think becomes stateless and everything is
about the = mutex?
 
 
What is the = downside?
 

Condition variables are allowed to have = spurious wakeups.
This would "just" increase them. Too = much?
 

So, therefore, what would be wrong with the = following design?
 a mutex contains an event 
 and a number of = waiters, zero or non-zero 
 if a mutex is = exiting with a non-zero number of waiters, signal the = event
 

To handle Signal vs. Broadcast
method = 1:
 the number of waiters might be interlocked
 the = woken would decrement it
 if it isn't zero, signal the event = again
 

method 2:
 the number of waiters is both = an integer and a semaphore
 and the lock exiter raises the = semaphore by the the integer

 
method 3:
 it is = not an auto-reset event and there is a count
  and when the = count goes to 0, reset the event
 I think in this case you have = to maintain a "wait generation" 
 so that new = waiters don't prevent the count from ever hitting 0.

Consumers >> wait = >> for empty to non-empty.

The paper does not discuss alert but that isn't clearly a problem. Regarding a rewrite, I believe one can use the win32 alert mechanism and owner = GetCurrentThreadId, thereby allowing threads not created by m3 runtime to participate.

The GC stop-world code can simply notice they are blocked and not try to signal them, but just set their status to stopping. When the blocked thread returns from the blocking call it can notice the stopping state and transition to stopped, waiting on the stop-world semaphore. This appears to be what the Kaffe VM folks do. The unfortunate thing is that this is *totally unnecessary* on every other platform except OpenBSD, as far as I know. We do not want to add cruft to the thread primitives just to support a broken user-level threads system. Better just to revert OpenBSD to our own user-level ThreadPosix implementation until OpenBSD wakes up to the real world of SMP and multicore.

It looks as if things went OK. Ths only difference I noticed is that I ended up with a cvs/sup directory as well as a cvs/cm3/sup directory. My guess is that it's something that cvsup uses to keep track of things so I rerun cvsup to get updates efficiently. But why do I get two of them?

Might it confuse cvsup? The one on the server is just a relict, I guess. You only need the local one. CVSup keeps a checksum list there. You can delete it, but it will speed up things if it exists.

The order of two unlocks is reversed. It probably doesn't matter. He says LockMutex/UnlockMutex are just P/V. Ours is a bit different. We have queueing on our locks which appears unncessary, but is maybe with in mind an optimization mentioned but now shown by Birrel -- that of Signal with a lock held transfering a thread right to the mutex's wait list. Birrel also has one mutex per condition variable but that seems to maybe be incidental and not architectural. I believe there is much room for performance improvement here, but if it is correct, it is ok for this release. As well, I believe lock/conditionvariables can be made to work in threads not created by the Modula-3 runtime, at least with a dependency on NT4 or Win2000 (QueueUserAPC to trigger alert). (owner = GetCurrentThreadId instead of T). I put in a bunch of RTIO in Juno. Whenever it hangs, the Signal call doesn't actually occur. We have to try to figure out why. It is something in the Misc/misc calls. So ThreadWin32.m3 is fairly well vindicated (except maybe via some roundabout fashion). The heap corruption is now fairly rare in Juno. I don't know if it is consistent or not. The contents are, not sure of the address. I'll debug more. My next idea..since I think the corruption involves copying a pixmap over other data, is to alter all pixmaps to be composed of specific data, see if that occurs in the corruption, to try to confirm this part of my theory. If that holds, then the memcpys done by gc could check for the pattern (actually they could check anyway, I thought I tried that already, will try again). As well, with ThreadWin32.m3 having gotten some fixes, getting various timestamps of the source tree might be a good idea. With ThreadWin32.m3 fairly well vindicated, we might declare the quality is high enough asis. ? But I'd like to keep investigating. (Anyone else can?) The doubt imho is now more cast upon the Win32 Trestle code. We might even try Cygwin configured to use Win32 threads and X Windows and see if that has the same bug.

The pthread_suspend_all_np() function interrupts all threads except the current thread and places them in a suspended state. The pthread_resume_np() function resumes a thread suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_all_np() function resumes all threads suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_np() and pthread_resume_all_np() functions have no ef- fect on threads that have not been suspended. Suspending and resuming a thread has an effect similar to that of receiv- ing a signal, namely that resumed system calls will return an error value of EINTR. RETURN VALUES The pthread_suspend_np() and pthread_resume_np() functions fail if: [ESRCH] No thread could be found corresponding to that specified by the given thread ID.

Agreed. > The only reason to have it in the CV is to achieve the optimization, > so you know to which mutex queue we should transfer the signalled/broadcast thread. Of course. I should have realized that. Um..the data is available anyway though, isn't it? The thread had to call wait(mutex, condition) in order for signal(condition) to unlink him from the condition's waiters, the waiting thread can store the mutex in itself (he can only be waiting on one condition variable at a time) and the signaling thread can grab that. I think. In either case, I'm not too inclined to touch it for this release until we are sure there is a bug, and that looks unlikely at this point. We could try putting back your BroadcastHeap change? It also seems a little gross that the heap lock is a special case recursive mutex. It seems like we should have Mutex and RecursiveMutex, have either work with Condition, and have LockHeap/UnlockHeap/BroadcastHeap just be wrappers around that. More generally we should probably try to embelish Thread.i3 with more primitives I think. At least "interlocked" and "once", if not "event" and "semaphore". "once" could definitely see a fair amount of use. The rest maybe not, maybe they are too primitive and hard to get good use out of, hard to define portably/efficiently. Or maybe LockHeap/UnlockHeap recursive support could/should be removed and just stick with Mutex and Condition and nothing else? Well, reader/writer locks are nice. The "Little Book of Semaphores" seems to suggest ideas like "turnstile", "rendevous" and maybe others, though I'm not sure they are actually easy to think about (I don't seem able to keep up with the author :( ), and possibly a generalization of reader/writer, like an n/m/o lock where you have x classes of code and different numbers of them are allowed to have the lock. Reader/writer is 2 classes with unlimited/1 access. There is a case of read/insert/delete that can scale a bit better than reader/writer. And maybe a "thread local" mechanism? - Jay CC: m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] Juno/Thread/Win32 notes Date: Wed, 21 Oct 2009 21:56:21 -0400 On 21 Oct 2009, at 17:02, Jay K wrote: ThreadWin32.m3 almost exactly matches Birrel's design.

We have queueing on our locks which appears unncessary, but is maybe with in mind an optimization mentioned but now shown by Birrel -- that of Signal with a lock held transfering a thread right to the mutex's wait list. The queueing on mutexes does appear unnecessary, unless the optimization can be achieved. Birrel also has one mutex per condition variable but that seems to maybe be incidental and not architectural. The only reason to have it in the CV is to achieve the optimization, so you know to which mutex queue we should transfer the signalled/broadcast thread. I believe there is much room for performance improvement here, but if it is correct, it is ok for this release. As well, I believe lock/conditionvariables can be made to work in threads not created by the Modula-3 runtime, at least with a dependency on NT4 or Win2000 (QueueUserAPC to trigger alert). (owner = GetCurrentThreadId instead of T). Sure. I put in a bunch of RTIO in Juno. Whenever it hangs, the Signal call doesn't actually occur. We have to try to figure out why. It is something in the Misc/misc calls. What are the Misc/misc calls? So ThreadWin32.m3 is fairly well vindicated (except maybe via some roundabout fashion). The heap corruption is now fairly rare in Juno. I don't know if it is consistent or not. The contents are, not sure of the address. I'll debug more. My next idea..since I think the corruption involves copying a pixmap over other data, is to alter all pixmaps to be composed of specific data, see if that occurs in the corruption, to try to confirm this part of my theory. If that holds, then the memcpys done by gc could check for the pattern (actually they could check anyway, I thought I tried that already, will try again). The corruption comes outside of GC. It's just that the GC dicovers it. This should really be straightforward to catch, if you can make it occur deterministically. As well, with ThreadWin32.m3 having gotten some fixes, getting various timestamps of the source tree might be a good idea. With ThreadWin32.m3 fairly well vindicated, we might declare the quality is high enough asis. ? But I'd like to keep investigating. (Anyone else can?) The doubt imho is now more cast upon the Win32 Trestle code. We might even try Cygwin configured to use Win32 threads and X Windows and see if that has the same bug.

Not that I see. They probably don't scramble in setjmp/longjmp though?

The pthread_suspend_all_np() function interrupts all threads except the current thread and places them in a suspended state. The pthread_resume_np() function resumes a thread suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_all_np() function resumes all threads suspended with pthread_suspend_np() or pthread_suspend_all_np(). The pthread_resume_np() and pthread_resume_all_np() functions have no ef- fect on threads that have not been suspended. Suspending and resuming a thread has an effect similar to that of receiv- ing a signal, namely that resumed system calls will return an error value of EINTR. RETURN VALUES The pthread_suspend_np() and pthread_resume_np() functions fail if: [ESRCH] No thread could be found corresponding to that specified by the given thread ID. The pthread_suspend_np() function fails if: [EDEADLK] Attempt to suspend the current thread. SEE ALSO pthread_cancel(3), pthreads(3) STANDARDS The pthread_suspend_np(), pthread_suspend_all_np(), pthread_resume_np() and pthread_resume_all_np() functions are non-portable and may not be supported with the above semantics on other POSIX systems.

"once" could definitely see a fair amount of use. The rest maybe not, maybe they are too primitive and hard to get good use out of, hard to define portably/efficiently. Or maybe LockHeap/UnlockHeap recursive support could/should be removed and just stick with Mutex and Condition and nothing else? Well, reader/writer locks are nice. The "Little Book of Semaphores" seems to suggest ideas like "turnstile", "rendevous" and maybe others, though I'm not sure they are actually easy to think about (I don't seem able to keep up with the author :( ), and possibly a generalization of reader/writer, like an n/m/o lock where you have x classes of code and different numbers of them are allowed to have the lock. Reader/writer is 2 classes with unlimited/1 access. There is a case of read/insert/delete that can scale a bit better than reader/writer. And maybe a "thread local" mechanism? - Jay CC: m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] Juno/Thread/Win32 notes Date: Wed, 21 Oct 2009 21:56:21 -0400 On 21 Oct 2009, at 17:02, Jay K wrote: ThreadWin32.m3 almost exactly matches Birrel's design. The order of two unlocks is reversed. It probably doesn't matter. He says LockMutex/UnlockMutex are just P/V. Ours is a bit different. We have queueing on our locks which appears unncessary, but is maybe with in mind an optimization mentioned but now shown by Birrel -- that of Signal with a lock held transfering a thread right to the mutex's wait list. The queueing on mutexes does appear unnecessary, unless the optimization can be achieved. Birrel also has one mutex per condition variable but that seems to maybe be incidental and not architectural. The only reason to have it in the CV is to achieve the optimization, so you know to which mutex queue we should transfer the signalled/broadcast thread. I believe there is much room for performance improvement here, but if it is correct, it is ok for this release. As well, I believe lock/conditionvariables can be made to work in threads not created by the Modula-3 runtime, at least with a dependency on NT4 or Win2000 (QueueUserAPC to trigger alert). (owner = GetCurrentThreadId instead of T). Sure. I put in a bunch of RTIO in Juno. Whenever it hangs, the Signal call doesn't actually occur. We have to try to figure out why. It is something in the Misc/misc calls. What are the Misc/misc calls? So ThreadWin32.m3 is fairly well vindicated (except maybe via some roundabout fashion). The heap corruption is now fairly rare in Juno. I don't know if it is consistent or not. The contents are, not sure of the address. I'll debug more. My next idea..since I think the corruption involves copying a pixmap over other data, is to alter all pixmaps to be composed of specific data, see if that occurs in the corruption, to try to confirm this part of my theory. If that holds, then the memcpys done by gc could check for the pattern (actually they could check anyway, I thought I tried that already, will try again). The corruption comes outside of GC. It's just that the GC dicovers it. This should really be straightforward to catch, if you can make it occur deterministically. As well, with ThreadWin32.m3 having gotten some fixes, getting various timestamps of the source tree might be a good idea. With ThreadWin32.m3 fairly well vindicated, we might declare the quality is high enough asis. ? But I'd like to keep investigating. (Anyone else can?) The doubt imho is now more cast upon the Win32 Trestle code. We might even try Cygwin configured to use Win32 threads and X Windows and see if that has the same bug.

You think that could be a problem? Most platforms use 8K. This used to have to relate to the hardware, when there was VM-synchronized GC, but no longer.

I mean, you know, that is the only one anyone here has expressed a recent desire to use, and used it and it was made to work. He can locally edit m3makefile. - I don't know of any significant platform without pthreads except NT and hypothetical DJGPP (Linux 2.4 mentioned below) - The following I know don't have make/get/set/swapcontext: any version of Cygwin, and I suspect not worth worrying about any version of NT, and I suspect not worth worrying about I don't think fibers are viable but maybe. Fibers don't interact propertly with any locking construct except Interlocked. e.g. critical sections nor any kernel object "work". Win7 has "user mode scheduling" that addresses problems with fibers but I think only on 64bit? any version of OpenBSD Darwin <=10.4; I synthesized them for PowerPC/10.4; you might try that (I found the PowerPC compat on x86 to be not very good though, maybe that was debugging only). - I think HP-UX manpage has strong warnings about these functions, being very version specific/fragile or something. But HP-UX has pthreads. - old Linux 2.4 still seems to be in somewhat active use, in specialized areas -- my router and a networked hard drive I have; pthreads is there I think, but not NPTL. I wonder if we should have I386_FREEBSD_USERTHREADS I386_LINUX_USERTHREADS SPARC_SOLARIS_USERTHREADS? and give them decent test/Hudson/release coverage? Maybe I386_FREEBSD4_USERTHREADS I386_LINUX24_USERTHREADS To "ghettoize" them via naming only, though they'd actually work and be tested on current systems? That is, you know, make userthreads work a bunch, be more portable, maintainable, great, then what? They still sit unused/unbuilt/untested? How to fix that? At least built/testet? Maybe just with cm3 -D thing, don't release them, just build/test them regularly? > The advantage of this move will be to eliminate a large swath of "cloned" Good! Specific questions about specific platforms ask me? You can see the answer is kind of backwards -- notice how every platform I have introduced I didn't add user threads support for. Question is only then for old/dead/unused/dormant platforms, and most of them DO have pthreads these days. I have a few machines not setup or not powered on -- Irix (32bit and 64bit in one) and AIX (32bit and 64bit in one) and HP-UX/HPPA (32bit and 64bit in one), Linux/IA64 specifically are powered off. VMS/Alpha, VMS/IA64 HP-UX/IA64, Tru64 I haven't gotten up and running yet, but I think they all support pthreads a long time now so no big worry. I also don't have have Linux/PPC64 or Darwin/PPC64 capability yet. (I think after this release Linux/IA64 should be done and will require a small change -- it has "two stacks" to scan.) > but don't have easy access to existing ABIs for other targets Please try the ssh commands I sent? That'll give you OpenBSD. FreeBSD maybe but I think it is off. I can provide more but for purposes of this line of questioning doesn't seem criticla. Birch gives you Linux/AMD64 and, in (slow/VM) a fashion NT and maybe Cygwin. - Jay From: hosking at cs.purdue.edu To: m3devel at elegosoft.com Date: Fri, 23 Oct 2009 14:43:59 -0400 Subject: [M3devel] User-level threads using makecontext/getcontext/swapcontext I have a (slightly rough) derivative version of ThreadPosix working on I386_DARWIN (implemented more along the lines of the current ThreadPThread) which abstracts all the nasty C-isms into ThreadPosixC.c.

Message-ID: I just noticed..it appears that some ports historically catch SIGBUS and call SegV, and some don't install a handler for it. e.g. it looks like the Darwin platforms do this. In my porting of the signal handling code to C, I foisted this behavior on all platforms. Reasonable? Otherwise we could put #ifdef __APPLE__ around SIGBUS in RTSignalC.c. I think it is probably ok asis, or maybe even an improvement. - Jay -------------- next part -------------- An HTML attachment was scrubbed...

Does valloc restrict you to 64K pages? On 23 Oct 2009, at 09:16, Jay K wrote: Tony, a few months ago I changed the NT pagesize to 64K, so I could simply allocate with VirtualAlloc, and not waste any. You think that could be a problem? Most platforms use 8K. This used to have to relate to the hardware, when there was VM-synchronized GC, but no longer.

In-Reply-To: References: Message-ID: full disclosure: This version has the bug where non-standalone NT apps don't do set operations correctly. (This is fixed in newer source, related to dynamically linking to data instead of the usual functions.) I'll retest with standalone. If that survives hundreds of iterations I can go forward gradually and find when things broke. - Jay From: jay.krell at cornell.edu To: hosking at cs.purdue.edu Date: Mon, 26 Oct 2009 02:45:57 +0000 CC: m3devel at elegosoft.com Subject: Re: [M3devel] Juno/Thread/Win32 notes (crashing intermittently from way back when..)

Message-ID: On Windows I use: type \cm3\bin\j.cmd @echo off setlocal set a=1 :loop echo %a% \bin\x86\cdb -g -G Juno.exe @M3no-trestle-await-delete @M3paranoidgc set /a a=a + 1 goto :loop this runs Juno in a loop, in a debugger, until it hits an access violation. It prints how many times it has run before each run. -g means go right away at the start of the process -G means go past the end of the process set /a is for "arithmetic" (expression evaluation) What is the equivalent with gdb/sh?

Hudson hasn't built anything for about a month, so there have been no check-ins to the release branch. (1) Has the OpenBSD problem been fixed or worked around? If so, what are the relevant changes that should me merged from trunk? The ChangeLog shows a lot of commits on head... (2) Is there still a problem in Windows threads? Or are we just chasing a general access violation due to an unknown reason? Again, is this ongoing or should some changes be merged for the release?

In-Reply-To: References: Message-ID: Here's a better view of the problem, again in 5.2.6. Notice 00e15888 repeating in both threads' parameters. This seems like a simple "add a lock use somewhere" problem but I have little idea of Trestle's locking protocols, apparently a complicated topic. You know, somehow redisplay/reshape need more serialization, but I don't know exactly what. The call to Capture fails with a dereference of NIL in the LOCK use.

There was really just one main problem in Win32 threads, a copy/paste error I made a few months ago. It is fixed in release. OpenBSD we know the fix but not sure we'll get to it. There are still problems with mentor and/or Juno and/or Trestle, all Windows specific. To some extent there are problems going back years, but things seem to be much worse lately.

In-Reply-To: References: <20091021200537.2rpal2av1cosc4k4@mail.elegosoft.com> Message-ID: OpenBSD user-level threading should work one way (using getcontext/ setcontext./swapcontext/makecontext if available there) or another (emulating these using setjmp/longjmp and a documented approach to synthesizing thread stacks using sigaltstack). Pthread threading is unlikely to work on OpenBSD until they fully support rthreads, but since OpenBSD pthreads are user-level we might as well use our own ThreadPosix implementation. I don't know if the old (current RC branch) ThreadPosix will work on OpenBSD or whether it would be worth moving to the much improved version I implemented this weekend which is now on trunk.

In-Reply-To: References: <20091021200537.2rpal2av1cosc4k4@mail.elegosoft.com> Message-ID: Tony, I understand "as long as OpenBSD pthreads is userthreads, we might as well use our own" but I don't understand "pthread threading is unlikely to work on OpenBSD". Shouldn't it work pretty ok actually? Except for the suspend/resume stuff? It should be easy to have OpenBSD custom stuff like Darwin has custom stuff, right? I was of the impression that the stack could merely be heap allocated, but perhaps it takes more than that? get/set/make/swapcontext are not available as far as I know on OpenBSD, but I do have them working on OpenBSD/x86 and OpenBSD/ppc (no OpenBSD/ppc currently to test on, but not a big deal to bring up it and others). Regarding Windows I did remove the idle thread cache, which is good and bad. The removal was mismotivated, and it might be a good thing, might be a bad thing. - Jay CC: wagner at elegosoft.com; m3devel at elegosoft.com From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Subject: Re: [M3devel] Fwd: Re: Status of threads for RC4?

There was really just one main problem in Win32 threads, a copy/paste error I made a few months ago. It is fixed in release. OpenBSD we know the fix but not sure we'll get to it. There are still problems with mentor and/or Juno and/or Trestle, all Windows specific. To some extent there are problems going back years, but things seem to be much worse lately.

URL: From rcoleburn at scires.com Tue Oct 27 06:10:17 2009 From: rcoleburn at scires.com (Randy Coleburn) Date: Tue, 27 Oct 2009 01:10:17 -0400 Subject: [M3devel] organization of scripts folder Message-ID: <4AE6476E.1E75.00D7.1@scires.com> I would like to better understand the rationale behind the "scripts" folder in terms of how it is organized and supposed to be used. Here is the current folder structure: scripts +---config +---doc +---examples +---iphone | \---1 +---python +---regression \---win In the past, I had put some BAT/CMD scripts in the "scripts" folder with the intent that these would be placed in the "bin" folder of the target install. Later, the other subfolders were added, including the one named "win". It seems there are perhaps multiple intentions for the scripts folder. For example, there are scripts that one would use mainly in setting up, maintaining, or administering cm3. There are other scripts that would be useful for certain target platforms as part of the installed system. There may be other scripts useful for testing. I am almost finished with testing of a new script I want to be included in the "bin" folder of the installed system on Windows platforms. This script will replace some of the old ones I have out there. It is designed to work with Win2000, WinXP, and Vista, whereas my old scripts don't work well on Vista. I also have some scripts I've built that aid in rebuilding package sets based on the PkgInfo.txt file. Before I remove my old scripts and replace them with the new ones, I thought it best for us to think about how the scripts folder should be organized. As a first cut, I propose something along the following lines: scripts +---doc = documentation for stuff in the "scripts" folder tree +---dev = scripts used for system development, maintenance, admin + +---windows = dev scripts written for Microsoft Windows (BAT, CMD) + +---posix = dev scripts written for unix shell (sh, bash, etc.) + \---python = dev scripts written in python +---install = scripts that should be put in "bin" folder of target install + +---common = scripts common to all target platforms + +---windows = BAT/CMD scripts for Microsoft Windows + +---posix = shell scripts for POSIX platforms (sh, bash, etc.) + +---python = scripts written in python (applicable to any platform with python) + \---XXX = scripts for target platform XXX (XXX is name of platform) + (assuming XXX needs something special not covered above) \---test = scripts used for regression testing +---windows = test scripts written for Microsoft Windows (BAT, CMD) +---posix = test scripts written for unix shell (sh, bash, etc.) \---python = test scripts written in python What do you think?

That would be aplus besides the bash/bat command line language scripts and others to mantain the core system by itself without CM3IDE This new category (Scripts) could help in checking the scripting facilities in CM3IDE and further enhancements in terms of components, like those you are telling, Explorer context menu integration and possible similar add ons for Mozilla family and others like email readers and web browsers developed at DEC. As the examples Category is already present in CM3IDE would be nice to put the example scripts you mention to test CM3 system scripts for bootstraping, upgrading, testing and misc. processes to aid debugging (runtime views of M3 program parameters). Whether they can run in a common web browser interface would require harder work to make it inside CM3IDE or easier in DeckScape and WebScape web browsers. Actually hard work was made by professor Tian Zhao (UW-Milwaukee) and professor Jens Parlsberg ( Purdue University) to do type inference in NP-time for no-explicit typed obliq scripts, giving us an opportunity to implement it and help the compile/run process of obliq scripts (potentially giving an ahead of time ability to check and accept or reject some scripts) and why not, write distributed platform-independent no-explicitly typed code to produce the explicitly typed and reduce runtime overhead for better performance and improved documentation of obliq and friends scripts. Thanks in advance, hope it helps and generate some further rethinking of system scripts and new ideas on quake, obliq and friends to aid the CM3 and CM3IDE scripting engine integration enhancements. ? --- El mar, 27/10/09, Randy Coleburn escribi?: De: Randy Coleburn Asunto: Re: [M3devel] organization of scripts folder Para: "" Fecha: martes, 27 octubre, 2009 10:08 I install some of my scripts.?

Asunto: Re: [M3devel] organization of scripts folder Para: "" , "Randy Coleburn" Fecha: mi?rcoles, 28 octubre, 2009 6:03 Hi Randy: I think your idea sounds great, maybe scripts package structure clean up could help to define a "category" rather than an individual package in CM3IDE as a framework for scripting with quake, obliq, visualobliq, obliq-3d and friends, but as the CM3 builder powered support for scripting of quake, obliq and friends support already present in WebScape and DeckScape web browser programs that would help to develop "addons" for CM3IDE such as allowing distributed checking of M3, obliq, etc programs with Showheap, Shownew and Showthread views allowed for each program running; a "deck" (tab) per program of a given CM3IDE server on the web client DeckScape or WebScape browser just standalone or distributed view of it, giving the system a world of tools to delevop distributed served M3, obliq, etc programs. That would be aplus besides the bash/bat command line language scripts and others to mantain the core system by itself without CM3IDE This new category (Scripts) could help in checking the scripting facilities in CM3IDE and further enhancements in terms of components, like those you are telling, Explorer context menu integration and possible similar add ons for Mozilla family and others like email readers and web browsers developed at DEC. As the examples Category is already present in CM3IDE would be nice to put the example scripts you mention to test CM3 system scripts for bootstraping, upgrading, testing and misc. processes to aid debugging (runtime views of M3 program parameters). Whether they can run in a common web browser interface would require harder work to make it inside CM3IDE or easier in DeckScape and WebScape web browsers. Actually hard work was made by professor Tian Zhao (UW-Milwaukee) and professor Jens Parlsberg ( Purdue University) to do type inference in NP-time for no-explicit typed obliq scripts, giving us an opportunity to implement it and help the compile/run process of obliq scripts (potentially giving an ahead of time ability to check and accept or reject some scripts) and why not, write distributed platform-independent no-explicitly typed code to produce the explicitly typed and reduce runtime overhead for better performance and improved documentation of obliq and friends scripts. Thanks in advance, hope it helps and generate some further rethinking of system scripts and new ideas on quake, obliq and friends to aid the CM3 and CM3IDE scripting engine integration enhancements. --- El mar, 27/10/09, Randy Coleburn escribi?: De: Randy Coleburn Asunto: Re: [M3devel] organization of scripts folder Para: "" Fecha: martes, 27 octubre, 2009 10:08 I install some of my scripts. Not sure if anyone else uses them. Nonetheless, I know that for me some of these scripts make cm3 easier to use on Windows. For example, I have scripts that: 1. Start the IDE. 2. Set up all the paths and environment variables for operating cm3 and Microsoft linker / Visual Studio at the command shell. 3. Open a cm3 command shell window in a particular folder. I've integrated this with the Explorer context menu for even greater utility. 4. Automate building of multiple packages based on the concept of a project. etc. Perhaps others would have similar scripts that should be available as part of the install. So, I'm suggesting here that we make a conscious choice on a standardized way for folks to contribute such scripts with the intent that when the installs are built that these scripts get included. End users are free to use the scripts, not use them, or even remove them after the product is installed. What do others think?

The current layout has grown and was never 'designed'. Speaking as a naive Modula 3 user and installer (well, not so naive after all these years), I found the scripts confusing. The biggest problem was to distinguish scripts that were meant to be used directly by the user and those meant to be used by other scripts. I also found that the scripts were not adequately documented -- oh, they were documented enough that once you were familiar with them, you'd know where to look for detaile you had forgotten, but not so a beginner would find it easy to figure which to use in the first place. Any documentation of reorganisation that makes these distinctions clear would be welcome. > > However, we should make sure that nothing breaks when we move scripts > around, especially for regression testing in Tinderbox and Hudson. Well, if reorganising makes it easier to get our current release through regression testing, I'm all for it. But I'd say it's really important to get a release out -- at the moment we don't really have one that's adequate for someone newly sold on the merits of Modula 3. So if there's a signoficant risk of a reorganisatin delaying things, perhaps we should hold off a bit. It seems that the current RC3 is not really adequate -- important components like m3gdb don't install properly from the binary downloads directory. And RC4 is held up on regression testing which shows significant problems in a few packages (Juno ocmes to ming). These problems appear to involve the interaction between the package, garbage colletion, multitasking, and the details of particular platforms. They are difficult problems, and it is not at all clear that they can be solved quickly, or even whether they are regressions. I'd very much like to see a RC4 that fixes the problems we've already fixed in RC3. Some of them seem to be installation issues. At least, with a current RC4, flaws and all, we would know for sure whether the installation problems in RC3 have really been fixed. > So changing things is fine as long as we consider and correct the > potential damage.

I'm seeing non-deterministic behavior on Windows XP and Vista. I am building against the head branch. On multiple runs of each build cycle, I am getting different errors. That is, sometime a package will fail to build/ship on one build cycle, then it will work on the next. I've even gone back and tried to rebuild or reship individual packages that failed and most always they will build or ship fine. For a while, I thought it might be my antivirus program. But I am getting same behavior on two different machines and each machine has a different AV program. I'll keep investigating, but something is definitely wrong. I am going to try uninstalling my AV program on one machine just to see if that makes any difference.

In-Reply-To: References: Message-ID: ok, it's not always 12 bytes in and 4b4. but anyway.. Tony does this make sense? And the atached? I seem to have it failing on an almost consistent address now. So I set write breakpoints "around" it. The object is often at 0x1cf0008. So I set write breakpoints at 0x1cf0000, 0x1cf0004, 0x1cf0008. All the writes are within RTCollector. Hm. Or so I thought. The first few are not always. Surely some of the writes are correct. And some are not? I attached a debugging log. It just goes like: bp main g ba w4 0x1cf0000 "k;g" ba w4 0x1cf0004 "k;g" ba w4 0x1cf0008 "k;g" g I also tried: ba w4 0x1cf0008 "~*k;g" etc. to get all stacks but it didn't seem useful. You know, what if two threads touch an address at about the same time? The debugger might be ambiguous. But it seems nothing else was nearby. - Jay From: jay.krell at cornell.edu To: hosking at cs.purdue.edu; m3devel at elegosoft.com Date: Sat, 31 Oct 2009 14:21:43 +0000 Subject: Re: [M3devel] debugging paranoidgc?

I'm attaching a backtrace from one crash, but I think I also am seeing deadlocks in the threading system---my application goes catatonic. Of course it *is* possible it's a bug in my application, but it works on PM3 and on CM3 on PPC_DARWIN. Finally I'm still concerned about threading performance but in the light of the bugs it's hard to say much about it yet, I think... (The program in question is a highly multithreaded stock market simulator.)

PTHREAD(3) FreeBSD Library Functions Manual PTHREAD(3) NAME pthread -- POSIX thread functions LIBRARY POSIX Threads Library (libpthread, -lpthread) SYNOPSIS #include DESCRIPTION POSIX threads are a set of functions that support applications with requirements for multiple flows of control, called threads, within a process. Multithreading is used to improve the performance of a program. The POSIX thread functions are summarized in this section in the follow- ing groups: o Thread Routines o Attribute Object Routines o Mutex Routines o Condition Variable Routines o Read/Write Lock Routines o Per-Thread Context Routines o Cleanup Routines Thread Routines int pthread_create(pthread_t *thread, const pthread_attr_t *attr, void *(*start_routine)(void *), void *arg) Creates a new thread of execution. int pthread_cancel(pthread_t thread) ... IMPLEMENTATION NOTES The current FreeBSD POSIX thread implementation is built in two libraries, 1:1 Threading Library (libthr, -lthr), and N:M Threading Library (libkse, -lkse). They contain both thread-safe versions of Standard C Library (libc, -lc) functions and the thread functions. Threaded applications are linked with one of these libraries. SEE ALSO pthread_atfork(3), pthread_cancel(3), pthread_cleanup_pop(3), pthread_cleanup_push(3), pthread_condattr_destroy(3), pthread_condattr_init(3), pthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_init(3), pthread_cond_signal(3), pthread_cond_timedwait(3), pthread_cond_wait(3), pthread_create(3), pthread_detach(3), pthread_equal(3), pthread_exit(3), pthread_getspecific(3), pthread_join(3), pthread_key_delete(3), pthread_kill(3), pthread_mutexattr_destroy(3), pthread_mutexattr_getprioceiling(3), pthread_mutexattr_getprotocol(3), pthread_mutexattr_gettype(3), pthread_mutexattr_init(3), pthread_mutexattr_setprioceiling(3), pthread_mutexattr_setprotocol(3), pthread_mutexattr_settype(3), pthread_mutex_destroy(3), pthread_mutex_init(3), pthread_mutex_lock(3), pthread_mutex_trylock(3), pthread_mutex_unlock(3), pthread_once(3), pthread_rwlockattr_destroy(3), pthread_rwlockattr_getpshared(3), pthread_rwlockattr_init(3), pthread_rwlockattr_setpshared(3), pthread_rwlock_destroy(3), pthread_rwlock_init(3), pthread_rwlock_rdlock(3), pthread_rwlock_unlock(3), pthread_rwlock_wrlock(3), pthread_self(3), pthread_setcancelstate(3), pthread_setcanceltype(3), pthread_setspecific(3), pthread_testcancel(3) STANDARDS The functions with the pthread_ prefix and not _np suffix or pthread_rwlock prefix conform to ISO/IEC 9945-1:1996 (``POSIX.1''). The functions with the pthread_ prefix and _np suffix are non-portable extensions to POSIX threads. The functions with the pthread_rwlock prefix are extensions created by The Open Group as part of the Version 2 of the Single UNIX Specification (``SUSv2'').
