[Scons-dev] Subprocess issue on Linux?

[Leskinen, Eugene]

I have just place the stubprocess.py to /opt/python27/lib/scons-2.1.0/SCons/Platform/ directory and added 'import stubprocess' statement to SCons.Platfrom.posix module just after import subprocess:

This what worked for me.

Hi Dirk,

I am Eugene Leskinen and I am the stubprocess.py module author.
How do you import it?

Hi Jason,

I think yes, in that it does what should be done by the system under posix_spawn.. ie call vfork and execve.

Here is the last version of the monkey patch I have from the people working on it. It has a fallback to the classic fork exec if the API's don't exists. It seems to solve the main speed problem for us at the moment. I believe it still being tested to find possible issues.


I tried to let SCons run with this patch, but I'm not able to integrate the patching of subprocess.Popen() successfully. I always get an import error for SCons.Util, and fail to see where this is actually coming from:

scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
gcc -o d1_0/f00000_sconsbld_d1_0.o -c -Id1_0/lup000_sconsbld_d1_0 -Id1_0/lup001_sconsbld_d1_0 d1_0/f00000_sconsbld_d1_0.c
Traceback (most recent call last):
  File "/home/dirk/workspace/scons_dirkbaechle/src/engine/SCons/Platform/posix.py", line 42, in <module>
    import SCons.Util
ImportError: No module named SCons.Util
scons: *** [d1_0/f00000_sconsbld_d1_0.o] Error 1
scons: building terminated because of errors.

Does anybody have a clue and can give me a pointer? I'd like to compare the times for a clean build against the default sources.

Regards,

Dirk
