Title: Constant hang with 7763
Post by: ironhead on February 01, 2012, 10:45:06 pm
I've updated to the latest svn version (7763 as of this post) and it constantly hangs when CC is supposed to kick in (i.e. on the 3rd character).  I've done a '--debug-log-to-file' but since I have to kill the codeblocks.exe process, it's a truncated file (at 4096 bytes).  Is this a known issue?

I'm running codeblocks self compiled using MinGW gcc 4.6.2 on Windows XP Pro SP3.

I can confirm it hangs (Even in a very simple tiny code snippet)

I try to find the reason, but no success.

1, I debug it under gdb, and when it hangs, I pause the gdb, and check all the threads and call stack, I only find one:

One thread is halted in:
[debug]#5  0x65ed5270 in CodeCompletion::CodeComplete (this=0x3b9f458) at E:\code\cb\cb_trunk\src\plugins\codecompletion\codecompletion.cpp:968
Here is a cs enter, so the main GUI hangs.
The other thread has no useful information.

2, I try to enable the "#define CC_ENABLE_LOCKER_TRACK", and add '--debug-log-to-file', but when viewing the debug log file, I can't find anything wrong, the last message is:
Code
....
s_TokensTreeCritical.Enter() : ExpandItem(), E:\code\cb\cb_trunk\src\plugins\codecompletion\classbrowserbuilderthread.cpp, 1040
s_TokensTreeCritical.Entered() : ExpandItem(), E:\code\cb\cb_trunk\src\plugins\codecompletion\classbrowserbuilderthread.cpp, 1040
s_TokensTreeCritical.Leave() : ExpandItem(), E:\code\cb\cb_trunk\src\plugins\codecompletion\classbrowserbuilderthre

The ugly thing is: The main GUI hangs, so the cc_logger does not work anymore. :(

It does not hang here, neither on linux nor win7.

Did you do a real clean rebuild. I mean manually cleaned (devel, output, .objs and include/*.gch) to be absolutely sure no artefacts of a prior build are left ?
Or a fresh and clean svn checkout ?

Not here, too. You can try to add a #define CC_ENABLE_LOCKER_ASSERT in the compiler options of the CC target and re-compile this plugin. If it still hangs, it should not be the lockers.

I did a clean build. The strange thing is:
if I run the new build c::b under c::b, then the new c::b will hang.
If I run the new c::b separately, it does not hang.
EDIT both cases hang.

Odd, it hangs all the time for me.  This is on a fresh svn checkout (no previous builds done in the local repository).

It still hangs here(Windows XP) if I enable CC_ENABLE_LOCKER_ASSERT, so where is bug come from???

I fix a build error when enable CC_ENABLE_LOCKER_ASSERT in rev 7765.

I defined both CC_ENABLE_LOCKER_ASSERT and CC_ENABLE_LOCKER_TRACK in the code-completion target, executed a complete rebuild (after updating to 7765) and now C::B crashes whenever I load a project file.  I've attached the .RPT file for reference.

edit: I removed CC_ENABLE_LOCKER_TRACK and I'm now back to the original behaviour, in that C::B hangs when the CC list is supposed to show (this is with CC_ENABLE_LOCKER_ASSERT defined).

OK - I was able to reproduce and fixed that. In addition I also fixed the permanent ClassBrowserBuilderThread lock-up. However, for the latter I need some more time as there is one annoyance, so I won't commit.

Please revert (only CC!) to r7658 (maybe r7723 works, too) to fix. CC on trunk is not stable atm.

I can confirm that 7766 fixes the hang.  I look forward to testing the other fixes when they are ready. ;)
