Works now:
Code: [Select]
Project 'test' parsing stage done (30453 total parsed files, 1347032 tokens in 42 minute(s), 24.656 seconds).

Hi, jens, Did you remember how long will the batch parse take to parse the whole Linux source, when you did this last time(If I remember correct, maybe one year ago)?

No, and it would not give any answers about incfreasing or decreasing parse time, because this time I parsed 2.6.35 kernel sources, the last time it was 2.6.29 with only 21k files and a little more than a million tokens, but I will test with current trunk and give you feedback.
There may be a large number of duplicate tokens, tokens will not be in direct proportion with the time.

@polygon7
from the log, I can't find the hint where there is a infinite loop, it seem the token line becomes bigger and bigger.

But there should be some thing wrong in Parserthread, we will check it.
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

Without my changes (static variable for deug and some if-clauses in define) I can no longer use C::B to parse the 2.6.35 kernel.
If I run it from commandline, it eats up all my memory (up to ~4GB) and after some tome it crashes with an X-window error (resource temproary unavailable), if I run it through debugger it crashes with a segfault in wxPostEVent, if it tries to send a TaskDone-event.

thanks jens for the test.
From the "pure CC" log file before crash, I can't find any thing wrong, it seems the log was correct (parserthread works fine before crash).
So, the problem should happened before the crash.

@loaden, Maybe, we could add an option to "disable the macro expansion", then see if it still hangs or crash in this case.
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

My guess:
the crash happens, because the applications runs out of memory.

If I run it from commandline, it eats up all my memory (up to ~4GB) and after some tome it crashes with an X-window error (resource temproary unavailable), if I run it through debugger it crashes with a segfault in wxPostEVent, if it tries to send a TaskDone-event.

The crash occurs if I switch to the running C::B, if it's visible and I run it from inside C::B (through gdb) it crashes in wxPostEvent.
Maybe the size of the used buffers should also be traced.

If set the option "Editor > CC > C/C++ Parser > Parse complex macros" is no checked, will lead the time is less.

The second time (parsing without) was done immediately after closing the project, so that most of the files are still in the systems hdd-buffer.

Parsing the linux-kernel 2.6.35 only works with debug-output enebaled and redirected to a file (C::B uses up to 2.5 GB of memory and did not release it at project unload).
Using from within C::B or diretcly from console, either crashes C::B or freezes the whole system.

By the way,  the following patch is needed to make C::B compile without a warning if CC_XXX_DEBUG_OUTPUT is set to 2.
I did not change all places (should all be checked I think), only the places which lead to a compiler warning:

No, because the ParserThread instance of these files does not created.

Parsing the linux-kernel 2.6.35 only works with debug-output enebaled and redirected to a file (C::B uses up to 2.5 GB of memory and did not release it at project unload).
Using from within C::B or diretcly from console, either crashes C::B or freezes the whole system.
I can not reproduce in the Windows system, you can help find which file is causing the problem?
Thanks!
