Do you have the CC tooltips activated? Most of the time the crashes happen there.
Sometimes it happens, when I debug something, move the mouse over a variable and it crashes. Somewhere in AddToken.
It happens on complex projects: my work project, C::B debuggers branch. It is very rare crash, but it is quite annoying :(
Sometimes it happens, when I debug something, move the mouse over a variable and it crashes.Do you enable the option: "Compiler and debugger settings > Debugger settings > Evaluate expression under cursor" ?
Yes, I always have it enabled.
what is the exact steps to product the crash???Hi, ollydbg, Do you remember the option: "Compiler and debugger settings > Debugger settings > Evaluate expression under cursor".
I don't have such crash when debugging, if the debugee crashed, you can at least see the debug-log message.
I suggest you turn off that option "Compiler and debugger settings > Debugger settings > Evaluate expression under cursor", because when the mouse hover a variable which is not initialized.(e.g. an un-initialized std::vector), then gdb will crash. :DAt the same time, CC doing buffer parsing for local variable.
Loaden: The debugger plugin runs in the main thread and has no access to the CC data structures.In sometimes, I don't believe GDB's backtrace.
The backtrace points to AddToken in the CC plugin, so it is definitely CC crash.
And this crash happens during code editing, too.
I'll give you the backtrace the next time it happens. At the moment I'm on linux debugger's branch head.
1. The backtrace is from the build in crash handler in C::B, not GDB.OK, Please try the latest reversion, at least rev7188.
2. GDB on linux is totally different beast to GDB on windows
3. The backtrace looks pretty normal, no strange things in it.

CodeCompletion::OnValueTooltipSo, this crash happens when user hover on the editor.
I guess there is some memory corruption happening somewhere, because a bug in std::set is highly unlikely.Please try rev7281.
Loaden any thoughts or ideas?

@loaden:
I just look at the crash call stack OBF posted, I found that
Do we need to do the "parser“ and "TokensTree" locking when we are calling function ParseBuffer()?
It seems that I can't find any lockers in the call function chain. so, it seems the shared resource was not protected. :D
PS: As OBF's crash call stack was in debugger branch, so I only review cc's code in this branch. (not trunk).
size_t NativeParser::MarkItemsByAI(ccSearchData* searchData, TokenIdxSet& result, bool reallyUseAI, bool isPrefix,
bool caseSensitive, int caretPos)

Does the parser test project work on linux?So, you use the "parsertest-unix.cbp", that file is exacted to work. but mostly I'm using the "parsertest.cbp" under Windows.
For me it crashes badly on strange places :(

I just look at the crash call stack OBF posted, I found that
Do we need to do the "parser“ and "TokensTree" locking when we are calling function ParseBuffer()?
It seems that I can't find any lockers in the call function chain. so, it seems the shared resource was not protected. :D
PS: As OBF's crash call stack was in debugger branch, so I only review cc's code in this branch. (not trunk).CodeThe locker added here.size_t NativeParser::MarkItemsByAI(ccSearchData* searchData, TokenIdxSet& result, bool reallyUseAI, bool isPrefix,
bool caseSensitive, int caretPos)
{
wxCriticalSectionLocker locker(s_TokensTreeCritical);
result.clear();
Parser::Parser(wxEvtHandler* parent, cbProject* project) :
m_Parent(parent),
m_Project(project),
m_UsingCache(false),
m_Pool(this, wxNewId(), 1, 2 * 1024 * 1024), // in the meanwhile it'll have to be forced to 1

{
m_TokensTree = new TokensTree;
m_TempTokensTree = new TokensTree;

ConnectEvents();
}I'm very surprised that why the critical section object is defined in the header file?A fatal mistake!
see: token.hCode// Make sure already entered a critical section if TokensTree related!
static wxCriticalSection s_TokensTreeCritical;
This means if two cpp files were include token.h, then the result is there are two critical sections for each cpp file.
Does that logical OK?
I found that there are many statement like "wxCriticalSectionLocker locker(s_TokensTreeCritical);"
in many cpp files. which means we have many critical section objects.
Loaden: Why are you using global critical section? Why don't you make it a member of the tokens tree (and then add Lock/Unlock methods or getCriticalSection() one)?I agree with you. the critical section should be the member of Tokenstree or maybe Parser class. using a global variable is a bad idea.

The crashes still exist?The original crash is 99% fixed. C::B has not crashed for the last couple of days.
The tooltip crash seems to be gone, but I've got a deadlock probably...
[...]
What I've done is:
1. Searched for a function in the symbol browser
2. The multi choice dlg showed
3. I've double clicked on a result
Another problem with the tree is that it is flickering very badly during code editing, on my Centos.did you enable the real time parsing (which means parsing while editing), see the code below:
void NativeParser::OnParserEnd(wxCommandEvent& event)
{
if (!Manager::IsAppShuttingDown())
Manager::Get()->GetLogManager()->DebugLog(_("NativeParser received parser end event."));
Parser* parser = static_cast<Parser*>(event.GetEventObject());
cbProject* project = static_cast<cbProject*>(event.GetClientData());
const ParsingType type = static_cast<ParsingType>(event.GetInt());
switch (type)
{
case ptCreateParser:
{
wxString log(F(_("Project '%s' parsing stage done!"), project
? project->GetTitle().wx_str() : _T("*NONE*")));
Manager::Get()->GetLogManager()->Log(log);
Manager::Get()->GetLogManager()->DebugLog(log);
CC_PROFILE_TIMER_LOG();
}
break;
case ptAddFileToParser:
Manager::Get()->GetLogManager()->DebugLog(F(_T("Add files to parser for project '%s'"), project
? project->GetTitle().wx_str() : _T("*NONE*")));
break;
case ptReparseFile:
Manager::Get()->GetLogManager()->DebugLog(F(_T("Reparsing modified files for project '%s'"), project
? project->GetTitle().wx_str() : _T("*NONE*")));
if (parser != m_Parser)
{
std::pair<cbProject*, Parser*> info = GetParserInfoByCurrentEditor();
if (info.second && info.second != m_Parser)
{
Manager::Get()->GetLogManager()->DebugLog(_T("Start switch from OnParserEnd::ptReparseFile"));
SwitchParser(info.first, info.second);
}
}
break;
case ptUndefined:
Manager::Get()->GetLogManager()->DebugLog(F(_T("Parser event handling error of project '%s'"), project
? project->GetTitle().wx_str() : _T("*NONE*")));
return;
}
if (!event.GetString().IsEmpty())
Manager::Get()->GetLogManager()->DebugLog(event.GetString());
UpdateClassBrowser();
m_TimerParsingOneByOne.Start(500, wxTIMER_ONE_SHOT);
event.Skip();
}Of course I have it enabled :)I just read some source code, and find that it use Freeze and Thaw, see:
Probably Freeze and Thaw should be used?
void ClassBrowserBuilderThread::BuildTree(bool useLock)Unfortunately it crashed again :(The crashes still exist?The original crash is 99% fixed. C::B has not crashed for the last couple of days.

And another lockup (dead lock probably!):Unfortunately it seems the real-time parser causes more problems than benefits. I've disabled this for a while now and in fact all my crashes are gone (well also, due to the latest fixes in CC).Code#8 0x00002aaab3bb5dd9 in CodeCompletion::OnRealtimeParsing (this=0xa1fbcd0, event=...) at codecompletion.cpp:3267
Interesting to note that you had queried to goto a declaration with a resulting message box (true?!) while Re-parsing kicked in - but there should actually be no changes when swapping header/source, or what did you do?Code#8 0x00002aaab3bb5dd9 in CodeCompletion::OnRealtimeParsing (this=0xa1fbcd0, event=...) at codecompletion.cpp:3267

I was editing the source code. Almost all crashes/lockups happen after I've edit the source code.Just for convenience: Can you try if theses crashes still happen if you disable the real-time parsing? I would guess it'll be way more stable then.
Yes, I've disabled 'Update parse when typing', I hope this is what you mean by real time parser.Yes, that's what I meant. So the kick-in is not caused by that. :-(
....So the kick-in is not caused by that. :-(My mistake, I should have said - "I've just disabled it, lets see if the crashes are happening still!"
The "calltip crash" (the one in the std::set), just happened, so it is not related to the realtime parser.I don't know how to use valgrind.
This time it happened during debugging :( (99% of the time it was during debugging, but I guess this is just caused by the usage pattern).
Maybe it is time to start running it under valgrind.

Loaden: Why are you using --xml=yes and --xml-file? They are ment for application parsing, not human parsing.I am using CB's Valgrind plugin.
Try from the command line, there is more output there.Here is the full log.
And you're trying it on a big project for long time? If you just start C::B move around for a minute and quit, you'll find nothing.

Edit: I cannot extract the last two files.You'll need a quite recent (beta) version of 7-Zip.

7z can create volumes, with a maximum size, useful if there is a size-limit like for the attachements on the forum.Sorry, I should say how to unpack it.
I don't know the correct way to unpack on linux, maybe there is some commandline for it, but I did not fiind.
What works: cp test.log.7z.001.7z test.log.7z and cat test.log.7z.002.7z >> test.log.7z and the unpack test.log.7z as usual.
By the way, can we add "xz" file types for attachments?Yes, but what is a "xz" file?
http://en.wikipedia.org/wiki/Xz (http://en.wikipedia.org/wiki/Xz)By the way, can we add "xz" file types for attachments?Yes, but what is a "xz" file?
http://en.wikipedia.org/wiki/Xz (http://en.wikipedia.org/wiki/Xz)Another one? I already got used to tar.bz, bz2, zip, 7z, rar, ace... what else will follow? And as HDD disk space it cheap these days, why saving a few more bytes? I think we should stick with the formats that are supported by one extraction tool, namely 7z , (Win)ZIP or (Win)RAR. This will avoid forum messages like "What filetype is xz" and "I cannot open file "xz" in Code::Blocks (no, it's an archive :shock:) and "what tool do I need to extract "xz"? and alike. ;-) :lol:
Because the forum attachment size is limited to 128KB, and XZ has a higher compression ratio.http://en.wikipedia.org/wiki/Xz (http://en.wikipedia.org/wiki/Xz)Another one?

BTW:You'll need to use the C::B command line option to log to a file in that case.
The CCLockerTrack class is useless, because when you get a dead lock, you cannot inspect the debug log.
Or do I miss something?

Good luck fixing it and please do more testing before committing a fix...
Especially on linux.
Try rev7419?Unfortunately it crashed again :(The crashes still exist?The original crash is 99% fixed. C::B has not crashed for the last couple of days.
Same backtrace... and again it has happened, when I was hovering with the mouse over a variable :(
After the next merge :)Remember: Disable symbols browser! :D
The current debugger_branch revision is working relatively stable :)
killerbot: can you make a nightly build for trunk?
what is the current state of CC on one hand with respect to stability ?The current HEAD works well on Windows 7 or Linux Mint 11.
The current HEAD works well on Windows 7 or Linux Mint 11.You said that the last time, too 8)
If only test from me, then, yes, It has been stable enough.The current HEAD works well on Windows 7 or Linux Mint 11.You said that the last time, too 8)

Just started testing the next changes in CC and it seems it is stable. 2-3 hours only.I stumbled over it also:
But there is one problem in the latest versions (not sure when it stopped working): Completion for the includes doesn't work.
I'm typing "#include <st|" then pressing ctrl+space and nothing shows. (| is where my cursor is at the moment, when I pressed ctrl+space).
This feature used to work at some time and it was great:)
Latest debugger branch on Centos Linux 5.6 amd64 with gcc-4.1.2
@all devs:me too :)
I would prefer, not to change former behaviour, if settings are made configurable.
Just started testing the next changes in CC and it seems it is stable. 2-3 hours only.Me too, but I found a crash pretty fast (on Windows), luckily its already fixed in head.

Here is a patch that should fix the problem: http://smrt.is-a-geek.org/codeblocks/patches/goto_declr_deadlock.patchI review the patch, but I don't think this patch release the lock before showing the selection dialog.
Please test and report if there are problems, if there are no problems in the next couple of days, I'll commit it.

And how do you make threaded programs correct without lockers?I suggest do not generate "suggestion list" when parserthread is running. This can avoid a lot of lockers in CC's code.
How would you know if the thread is not running?This also involve a shared resource, but we can check/lock the state when we enter the handler function.
