[M3devel] more info on ticket 1082 wrt start /wait

[Jay K]

Start /wait is always doing the same thing, it is always waiting. But what it is launching is deciding to exit right away, or not.

More later..

Jay et al:
 
Well I’ve done more testing.
 
Jay you are right about the multiple instances.  For both IE8 and FireFox on Vista, if you already have an instance running and use “START /WAIT” to get another
 instance, the second instance starts up (a new window) and the “START /WAIT” immediately returns rather than waiting.  Conversely, if this is the first instance of IE8 or FireFox, then “START /WAIT” does indeed wait for the browser to close before it returns. 
 I’ll have to get to an XP machine to confirm if this same behavior occurs there as well.
 
If you go back to IE6, it didn’t have Tabbed windows, so maybe that is why “START /WAIT” always waited.
 
I don’t have an immediate fix for this behavior since the original design used the “START /WAIT” functionality on Windows.  On POSIX, it doesn’t.  The quick
 fix I mentioned earlier is probably the best thing to do now.  I could perhaps modify the sources to change the default CFG to “return FALSE” on Windows instead of “return TRUE”, thereby implementing the quick fix for everyone.  I’ll check into this shortly.
 
As for your comments about cm3ide not being “great” that is your opinion; however, back in the day when reactor (aka cm3ide) first came out, this was indeed
 leading edge stuff.  The idea that you could tweak your IDE by making simple HTML file changes I think was pretty novel at the time, and the thinking from the CMass Inc folks was that as the browser improved, your IDE would improve automatically (e.g. multiple
 tabs was a subsequent browser improvement).
 
Even though you may not consider CM3IDE to be a great IDE, I do find that it is extremely helpful during development when browsing source code and looking
 up interface specs.  With just a hyperlink, you can quickly find what you are looking for.  It also has a lot of built-in links to reference material and coding examples.
 
Note that cm3ide hasn’t really changed much at all since reactor first debuted.  Now that we finally have the open-source release, we can modify it to make
 it better.
 
Regards,
Randy

What if you just simply:

  "start http://localhost:whateverport" 

 

Personally I find cm3ide/reactor to be ..not great.

 

The behavior you are noticing is that the web browser might decide there is another adequate instance of it running and ask it to display something and exit.

 

You will likely find different behavior depending on if an instance of the browser is already running.

There might also be a command line option to control this.

But I think your best best is just not to use /wait.

Ok, I’ve done a bit more testing.
 
I don’t think the problem has to do with “START /WAIT …” but rather it seems to be a difference in Windows Internet Explorer.
 
When your browser is set to FIREFOX instead of IE, the “START /WAIT firefox.exe” command works fine, so you can keep the “return TRUE” in the CM3_IDE.cfg
 file.
 
But, when using IE8, the “START /WAIT iexplorer.exe” command does not wait for IE8 to terminate and returns immediately, thus the “return TRUE”
 in CM3_IDE.cfg must be changed to “return FALSE” to prevent immediate shutdown of CM3IDE.
 
If I go to a Windows 2000 box running IE6, the “START /WAIT” again seems to wait for IE to terminate.  I haven’t tested yet with IE7 to see if
 it behaves correctly or not.
 
So for now, folks may want to use FireFox instead of IE with CM3IDE.
 
Regards,
Randy
