RE: [cdt-dev] MBS wizard extension debugging
|
Leo, I am not doing a sync()... or async()... just running in the thread
that the Runnable is called on...
should I be doing that any differently?
The only data access I'm doing is reading and writing preferences, and
MBSCustomePageManager's pageProperty values.

Just a wild guess..., but could there be some kind of multithread
problem with code in the runnable and other parts of Eclipse/CDT? For
example, concurrent access to data?

Without seeing the code in question I can't really help too much I'm
afraid. "Works for me."
How minimal is your Runnable? Also, what platform are you running on?

[cdt-dev] MBS wizard extension

I am having strange problems trying to debug some MBS extensions... I
added
a wizard page for C Managed Build projects, with a Runnable that runs at
the end
of the wizard, to incorporate user's selections made in my wizard page.
Thanks to Chris Recoskie for some pointers to know what to try... I'll
document all this when I get it working...
But I can't even get all of the Runnable to run...
I have had problems with cygpath.exe errors, and JVM segfaults.
I'm on Windows XP.
I have upgraded cygwin to the most recent everything, got Eclipse 3.2
RC6
(was RC4) and CDT RC2 (nightly build from 5/30) plus CDT code from head
on
some projects yesterday.
Finally to try to avoid segfaults I got the Sun JVM 1.5 for 'installed
JRE"
(I was using the IBM JVM).
The segfaults & "unknown bytecode" errors have stopped but now the
intermittent behavior in the wizard's execution seems to have
returned...
I'm not certain that the JVM change really 'fixed' things. Just changed
the symptoms.
My wizardPage ctor always runs... I can see from a println...
but often the Whole "New C Managed Build Project" wizard doesn't run.
Then
sometimes the "New C Managed Build Project" wizard runs, but my wizard
page
doesn't show up.
It seems to vary depending on if I select :
(1)New.. Project then select " C > Managed Make C Project " from the
first
wizard page
or
(2) New > " Managed Make C Project" directly from the context menu.
Do these take two different routes?
Route (1) seems more reliable... at least the wizard has already started
so
it proceeds. But then sometimes my page isn't at the end... even though
the ctor has already run.
I can dramatically (consistently) change the behavior of the above
wizard
if i simply comment out part of the code in my Runnable.
So simply having the code compiled in seems to affect whether or not the
wizard, or the wizardpage, that it's attached to (via extensionPt)
actually
gets shown.
This is very strange, 'feels' like a JVM problem still, to me.
I also have discovered that it seems I need to catch all errors in my
wizard page that extends MBSCustomPage, and the Runnable, regardless of
if
the compiler forces me to,
or else it dies down in the bowels of Eclipse platform code somewhere.
try/catch around entire method seems safer now. Should this be so?
But right now, I can't even get it to fail this way, since changing the
JVM.
I just switched to using Sun's JDK 1.5 for both my development version
of
Eclipse, *and* the runtime JRE. Same behavior.
So, i seem to be stuck. I can't get much of anything useful to run in a
Runnable() attached to my wizard page.
Am I going crazy???
