I'm still waiting for changes and fixes committed to the release branch concerning threading and segmentation violations on Windows. Unfortunately I cannot spend as much time for release engineering currently as in the summer. I can only release what is available.

It looks like you are using an old ThreadPThread. The installation archives haven't been updated for many weeks. I'm still waiting for corrections wrt. Windows; but perhaps I'm not up-to-date? A complete release build on all platforms will take about a week (it _should_ be faster, but this is my experience from the frist three :-/). If I should start building RC4 on the release branch just let me know. I'll care for it then.

Should I cvs update to something else to try? Note that what's in the "normal" CVS head didn't even compile when I tried it---see an earlier email from me. How can I specify the proper tag to get on to the "release" branch of the tree, if that's what I'm supposed to do?

(Whether the implementation actually prohibits it or not is an implementation decision.) The point is that we should be free to give the error in some later implementation, so as to not to restrict what semantics the implementation must support.

In-Reply-To: References: Message-ID: > (Whether the implementation actually prohibits it or not is an implementation decision.) Tony, I'm sympathetic to the smaller version but I think it is wrong. "It is a checked runtime error to call this more than once for any t" is a much different/stronger statement than e.g. "it is implementation defined what happens if you call join more than once for any t". The printed Reactor 4.1 docs have the same comment as current Thread.i3. You know, ideally if I write: Thread.Join(t); Thread.Join(t); and it works today on any system, it will continue to work on all systems. I think "implementation defined" is something Modula-3 tries to have less of. On the other hand, I think if we foresee it to work trivially on all forseeable implementations, we can change the interface by removing the comment. Win32 WaitForSingleObject(thread, INFINITE) is allowed multiple times, though that isn't the current implementation. - Jay From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Date: Mon, 2 Nov 2009 12:59:36 -0500 CC: m3devel at elegosoft.com Subject: Re: [M3devel] join twice? I don't know that there ever was a mandate that join can only be called once on a given thread. But, given that pthread_join is undefined when called more than once on the same thread we probably want to retain the comment. (Whether the implementation actually prohibits it or not is an implementation decision.) The point is that we should be free to give the error in some later implementation, so as to not to restrict what semantics the implementation must support.

Semantically, it doesn't make sense to join a thread more than once. Join is the compliment to Fork. With fork, one thread becomes two. With Join, two threads become one. After they've become one, the 2nd thread is no more, so you can't join to it anymore. IMO, the implementation should enforce this behavior. What would be the "benefit" of allowing more than one join? What does it "mean" to join a "dead thread"? Regards, Randy Coleburn >>> Tony Hosking 11/2/2009 11:54 PM >>> OK, sure. Fair enough.

"It is a checked runtime error to call this more than once for any t" is a much different/stronger statement than e.g. "it is implementation defined what happens if you call join more than once for any t". The printed Reactor 4.1 docs have the same comment as current Thread.i3. You know, ideally if I write: Thread.Join(t); Thread.Join(t); and it works today on any system, it will continue to work on all systems. I think "implementation defined" is something Modula-3 tries to have less of. On the other hand, I think if we foresee it to work trivially on all forseeable implementations, we can change the interface by removing the comment. Win32 WaitForSingleObject(thread, INFINITE) is allowed multiple times, though that isn't the current implementation. - Jay From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Date: Mon, 2 Nov 2009 12:59:36 -0500 CC: m3devel at elegosoft.com Subject: Re: [M3devel] join twice? I don't know that there ever was a mandate that join can only be called once on a given thread. But, given that pthread_join is undefined when called more than once on the same thread we probably want to retain the comment. (Whether the implementation actually prohibits it or not is an implementation decision.) The point is that we should be free to give the error in some later implementation, so as to not to restrict what semantics the implementation must support.

In-Reply-To: <4AEFF851.1E75.00D7.1@scires.com> References: Message-ID: To me..with a Win32 background..join means "wait for thread to finish". And there is a separate action "get thread result". You could consider these one merged operation "wait for thread to finish and get its result". In either case, it is reasonable to allow it multiple times. Waiting for a thread to finish that has already finished is just fast. Getting a thread result that you already got is also easy albeit usually unnecessary. Now, if the operation is "wait for thread to finish, get its result, and lose track of its result", that isn't idempotent. I'm torn.

And calling Thread.Fork several times on a single Thread.Closure is also idempotent? It may be "reasonable" to allow such things, but they almost always signal bugs in the calling code. Changing the specification to make them legal is in my opinion losing a valuable opportunity for preventing bugs. Note the Modula-3 philosophy, not everything reasonable (for a C programmer's definition of "reasonable", at least) is legal.

I for one, have always programmed with the understanding that the comment was enforced. IMO: If one needs to pass the result of a thread outside the thread's context, one should use an explicit mechanism or data structure (e.g., conditions, object data fields, etc.). If multiple threads need to wait for a thread to finish, that is the whole concept of a rendevous (see the "Little Book of Semaphores" you referenced earlier). If programmers must depend on multiple joins, when is it ever safe for the underlying infrastructure to "forget about" the dead thread and its return value(s), if any? At what point has it been "too long" for you to query about a dead thread's status/return values (millisecs, minutes, hours, days, weeks -- for long-running programs this can be problematic). I would argue that it is better for the programmer to be explicit in such matters. It is easy enough to implement given the capabilities of the language, and indeed, I've done so many times. Regards, Randy Coleburn >>> Jay K 11/3/2009 10:04 AM >>> To me..with a Win32 background..join means "wait for thread to finish". And there is a separate action "get thread result". You could consider these one merged operation "wait for thread to finish and get its result". In either case, it is reasonable to allow it multiple times. Waiting for a thread to finish that has already finished is just fast. Getting a thread result that you already got is also easy albeit usually unnecessary. Now, if the operation is "wait for thread to finish, get its result, and lose track of its result", that isn't idempotent. I'm torn. The existing implementations all either support multiple join or have to go out of their way to prevent it.

"It is a checked runtime error to call this more than once for any t" is a much different/stronger statement than e.g. "it is implementation defined what happens if you call join more than once for any t". The printed Reactor 4.1 docs have the same comment as current Thread.i3. You know, ideally if I write: Thread.Join(t); Thread.Join(t); and it works today on any system, it will continue to work on all systems. I think "implementation defined" is something Modula-3 tries to have less of. On the other hand, I think if we foresee it to work trivially on all forseeable implementations, we can change the interface by removing the comment. Win32 WaitForSingleObject(thread, INFINITE) is allowed multiple times, though that isn't the current implementation. - Jay From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Date: Mon, 2 Nov 2009 12:59:36 -0500 CC: m3devel at elegosoft.com Subject: Re: [M3devel] join twice? I don't know that there ever was a mandate that join can only be called once on a given thread. But, given that pthread_join is undefined when called more than once on the same thread we probably want to retain the comment. (Whether the implementation actually prohibits it or not is an implementation decision.) The point is that we should be free to give the error in some later implementation, so as to not to restrict what semantics the implementation must support.

The odd thing is just that the old "reference" user-level threads implementation never did the check, and permitted multiple joins.

I seem to recall that some of the interfaces got a rework and were published after the first printing of the book, but that the community adopted these as a whole to be "the spec" for M3. Maybe the comment in Thread.i3 became law at that point? In any event, I still argue that it doesn't make sense to do multiple joins and I agree with Mika that it is often a symptom of bad programming and we want the language to help us write less buggy code. So, I would vote that we don't make any changes to permit multiple joins. It may be true that the current implementation does not enforce the prohibition against multiple joins on all platforms simply because it was the easiest thing to do at the time. In this case, I argue that the implementation is not being totally faithful to the specification; but if the programmer heeds the spec, then there is no consequence to the implementation's lack of enforcement. Bottom line: Let's not devolve from the noble position of doing the right thing simply because the implementation has been less than faithful. Keep the comment and the prohibition and work toward improving the implementation over time to be faithful to the specification. (Does that make me a "practical idealist"?)

I for one, have always programmed with the understanding that the comment was enforced. IMO: If one needs to pass the result of a thread outside the thread's context, one should use an explicit mechanism or data structure (e.g., conditions, object data fields, etc.). If multiple threads need to wait for a thread to finish, that is the whole concept of a rendevous (see the "Little Book of Semaphores" you referenced earlier). Agreed. If programmers must depend on multiple joins, when is it ever safe for the underlying infrastructure to "forget about" the dead thread and its return value(s), if any? At what point has it been "too long" for you to query about a dead thread's status/return values (millisecs, minutes, hours, days, weeks -- for long-running programs this can be problematic). We can forget about the dead thread only when it is GC'd. No-one can call Join without a reference to it. I would argue that it is better for the programmer to be explicit in such matters. It is easy enough to implement given the capabilities of the language, and indeed, I've done so many times. Agreed. The odd thing is just that the old "reference" user-level threads implementation never did the check, and permitted multiple joins. And the threads spec in SPwM3 is silent on the issue. Regards, Randy Coleburn >>> Jay K 11/3/2009 10:04 AM >>> To me..with a Win32 background..join means "wait for thread to finish". And there is a separate action "get thread result". You could consider these one merged operation "wait for thread to finish and get its result". In either case, it is reasonable to allow it multiple times. Waiting for a thread to finish that has already finished is just fast. Getting a thread result that you already got is also easy albeit usually unnecessary. Now, if the operation is "wait for thread to finish, get its result, and lose track of its result", that isn't idempotent. I'm torn. The existing implementations all either support multiple join or have to go out of their way to prevent it. Yet Thread.i3 has been commented so presumably forever. - Jay Date: Tue, 3 Nov 2009 09:36:23 -0500 From: rcoleburn at scires.com To: m3devel at elegosoft.com Subject: Re: [M3devel] join twice? I think the comment in the code is correct. Semantically, it doesn't make sense to join a thread more than once. Join is the compliment to Fork. With fork, one thread becomes two. With Join, two threads become one. After they've become one, the 2nd thread is no more, so you can't join to it anymore. IMO, the implementation should enforce this behavior. What would be the "benefit" of allowing more than one join? What does it "mean" to join a "dead thread"? Regards, Randy Coleburn >>> Tony Hosking 11/2/2009 11:54 PM >>> OK, sure. Fair enough.

"It is a checked runtime error to call this more than once for any t" is a much different/stronger statement than e.g. "it is implementation defined what happens if you call join more than once for any t". The printed Reactor 4.1 docs have the same comment as current Thread.i3. You know, ideally if I write: Thread.Join(t); Thread.Join(t); and it works today on any system, it will continue to work on all systems. I think "implementation defined" is something Modula-3 tries to have less of. On the other hand, I think if we foresee it to work trivially on all forseeable implementations, we can change the interface by removing the comment. Win32 WaitForSingleObject(thread, INFINITE) is allowed multiple times, though that isn't the current implementation. - Jay From: hosking at cs.purdue.edu To: jay.krell at cornell.edu Date: Mon, 2 Nov 2009 12:59:36 -0500 CC: m3devel at elegosoft.com Subject: Re: [M3devel] join twice? I don't know that there ever was a mandate that join can only be called once on a given thread. But, given that pthread_join is undefined when called more than once on the same thread we probably want to retain the comment. (Whether the implementation actually prohibits it or not is an implementation decision.) The point is that we should be free to give the error in some later implementation, so as to not to restrict what semantics the implementation must support.

Put down three points in Juno, draw a curve using them (looping from one point back to itself, with the other two as control points). 2. Turn on the grid. 3. Move one of the control points around, so it snaps to the grid. 4. Move the other control point to the same spot. What happens on my AMD64_FREEBSD is this: (323)ginger:~/cm3/scripts>Juno Xlib: extension "Generic Event Extension" missing on display "rover:1.0". Assertion failed: (XLIB_SEQUENCE_COMPARE(dpy->last_request_read, <=, dpy->request)), function process_responses, file xcb_io.c, line 242.

Abort (324)ginger:~/cm3/scripts> now if it had crashed in Juno's M3 code I wouldn't be concerned, but it seems to be crashing in X code, which just sounds wrong... and it seems to crash in some sort of messaging queue code?

It looks like your Xserver showed an error on stderr. Perhaps this can be xclient crash handling Trestle client messages to xserver, that would explain this is not related to Juno-2 core functionality perse at least in LINUXLIBC6 box as I can tell, have you tested this standalone (Juno and Xserver in same machine, did you do in this way the crash happen) or in other platform or distributed between two different platform machines with their xclient and xserver? compiler version (cm3 -version) test at fbd-desktop:~$ cm3 -version Critical Mass Modula-3 version d5.8.2 last updated: 2009-07-15 compiled: 2009-07-20 04:36:35 configuration: /usr/local/cm3/bin/cm3.cfg host: LINUXLIBC6 target: LINUXLIBC6 My xorg xserver is running standalone (i.e not distributed).

Message-ID: Tony, any thoughts on merging/copying head to release? I'm willing to do work, review the diffs (which I'm going to do anyway), build stuff, test a little. But I don't likely understand it all in ThreadPThread.m3, RTCollector.m3, RTAllocator.m3. - Jay -------------- next part -------------- An HTML attachment was scrubbed... URL: From jay.krell at cornell.edu Thu Nov 5 18:35:47 2009 From: jay.krell at cornell.edu (Jay K) Date: Thu, 5 Nov 2009 17:35:47 +0000 Subject: [M3devel] removing vfork, general header cloning matters? Message-ID: I say we remove vfork from m3core. - We never use it in cm3. To be confirmed. - It cannot be portably wrapped in C without violating Posix. And is that theoretical or real? Posix says you can't return from the caller of vfork. It must exec or _exit. It'd be cool if we could have a jump or tail recursion but that's probably not feasible. Maybe a function pointer?? I can try that out. Would have to see if Posix allows vfork to be a macro through. We could declare a function pointer and then the C implementation could have an #ifdef around it -- not provide the function pointer on all platforms. - It doesn't have a portable name. Witness netbsd2-i386/Unix.i3. I assume that is correct or close? But maybe this is an "ideal" vs. "possible, works" case? (see below) IF we ever get to a system where vfork is advantagous against fork, uses should be written in C. Unless it can be shown that the NetBSD example is wrong, or unnecessary? I'm a little torn. In particular, "header cloning", despite my distaste, is not unique to Modula-3. And there is some good chance that the names are actually portable. You know, it might be more efficient on Linux to #include and get all the stat wrappers, the static libraries probably contain them in the "normal" way. If I get back to NetBSD and find they are compatible this way too, then maybe the current form is ok. You know, the question is..while types and constants are definitely an issue and reasonably dealt with, "function names" maybe aren't? Note that vfork doesn't really merit this level of discussion but I'd like to understand the general case. Maybe I just need to read more of the Posix spec and maybe it talks about link level naming vs. C source level constructs? Ie. maybe they talk about Ada, Pascal, etc. bindings?? (ie: maybe people really do support languages other than C via acceptable header cloning?) - Jay -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: > Feel free to ask if you have questions. On a different matter.... can you, um, explain garbage collection? Specifically barriers? And the five states? Are they just older/younger? I understand "the generational hypothesis". "Most objects die young". (Most objects could be stack allocated. :) ) And then there is a need to divide objects, at runtime, into older and younger. And then, there is some need to notice pointers that cross generations? That is, "old" usually includes no garbage, unless it has been changed since the last check, and then needs a new check? That is, a write barrier is a sort of copy-on-write, or notice-writes mechanism? A write into a generation means the gc needs to check it? That is, if you look at the Win32 GetWriteWatch API, that's what we are simulating sort of? (or vice versa)? I'm really guessing. And this doesn't explain what, if anything, a read barrier is. But then is meant by gray/impure/etc.? Maybe checkin RTCollector.readme? (note that read/write barriers are other things too -- ways to enforce (relative) order of executation). - Jay -------------- next part -------------- An HTML attachment was scrubbed...

In-Reply-To: References: Message-ID: For a description of the current concurrent CM3 GC algorithm I suggest you take a look at my ISMM'06 paper: http://www.cs.purdue.edu/~hosking/papers/ismm06.pdf . You are correct in stating that the write barriers used in the CM3 collector are used for generational GC, to keep track of updates to objects in the older generation. That way, when collecting just the younger generation we can focus our attention to those pages of the older generation that refer into the younger generation. Note that all surviving young objects are promoted into the older generation at every GC cycle. Thus, there are never young objects referred to by old objects at the end of GC. The read barrier is used to protect against mutator threads executing concurrently with the garbage collector from acquiring pointers to objects that have not yet been scanned by the garbage collector. We divide objects into those that are black (scanned by the garbage collector), grey (reached but not yet scanned), and white (not yet reached). At the end of the GC cycle unreached objects are garbage. The CM3 collector maintains an invariant that black objects can never contain pointers to white objects. Moreover, the read barrier ensures that mutator threads hold only pointers to black objects. This prevents the mutator from copying a pointer to a white object into a black object. Otherwise, the collector might never reach that white object and it would be freed even though it is reachable from the black object. Impure objects contain pointers. Pure objects are "leaves" in the object graph -- they contain no pointers.

POSIX does not say this. it says that behavior is undefined if the child of vfork() does anything other than exec or _exit. "undefined" means implementers are allowed to do anything they want otherwise (including crash). in reality, there is a lot you can actually do, but returning from the function that called vfork() is not one of them. in doing so, you most often modify the stack, and once the child does exit/whatever, the parent will see the mangled stack state and often crash & burn. > It'd be cool if we could have a jump or tail recursion > but that's probably not feasible. > Maybe a function pointer?? I can try that out. in practice, you can call as many functions after vfork() as you like. ultimately, the child needs to call exec or _exit, else the parent stays frozen indefinitely. > Would have to see if Posix allows vfork to be a macro through. > We could declare a function pointer and then the C implementation > could have an #ifdef around it -- not provide the function pointer on > all platforms.

In-Reply-To: <200911051419.51901.vapier@gentoo.org> References: Message-ID: Mike, thank you for the detailed response. "not wrapped (in C)" is: foo.i3 INTERFACE IFoo; <*external*> PROCEDURE Foo(); END IFoo. cm3 generates reference to "Foo". "wrapped (in C) is: foo.i3 INTERFACE IFoo; <*external IFoo__Foo*> PROCEDURE Foo(); END IFoo. cm3 generates reference to IFoo__Foo. foo.c #include whatever.h void IFoo__Foo() { Foo(); } To the extent that whatever.h is simply: void Foo(void); it doesn't matter. To the extent that whatever.h is inline void Foo(void) { ..stuff.. } or #define Foo Fooabcdef void Foo(void); or such AND that compatibility isn't provided for simply void Foo(void); wrapping is required. Or adapting the .i3 somehow, not portably. Wrapping is generally easy and safe and portable and wards of any such problems. Slightly wasteful, granted. However because the caller of vfork is undefined if it returns and often bad in practise (adopting/agreeing with what you say) this wrapping is not a good direction, for this particular function. Therefore stuck between contradictions. fork/exec vs. vfork/exec On current systems why does vfork ever win? Or win significantly? If it is a significant win, we can/should rewrite our fork use in C. (not necessarily the entire function, just the part up to exec/_exit). Even though vfork is no longer Posix, it is still widespread with matching semantics everywhere? Always either equivalent or slightly faster? The disappointing thing is that the system with the really really slow fork -- Cygwin -- has an identical vfork.

Always either equivalent or slightly faster? for what you want (a fast fork + exec), the semantics should be safe/portable. if you want to do anything more exotic (and thus outside the realm of POSIX 2004), i'm really only familiar with inner details of Linux. > The disappointing thing is that the system with the really really slow fork > -- Cygwin -- has an identical vfork. cygwin is slow all the time. focus on mingw if you want real windows support. not that i have any idea how much effort this would require for cm3 ... it's be a long time since i last looked at the code base after giving up on porting it to something reasonable (x86_64/Linux) let alone fun (hppa). -mike -------------- next part -------------- A non-text attachment was scrubbed...
