Hi all,
This short message to let you know about the current developments and plans,
after a few days of vacation and many hours of work on pythonOCC. The 0.4
release is planned for the end of this month (see the TODO list below).
Almost all features were implemented but there is still work to achieve on
the smesh integration part.
The last few days, I worked around two issues:
- compilation process is long, it takes almost one hour on recent machines.
I then multiprocessed the distutils based builder to parallelize the
compilation. It can be done (as with automake/SCons) by passing the -j
option. For instance:
python setup.py build -j2
First benchmarks show that the time necessary to compile the complete
solution is drastically reduced (almost divided by the numbers of cpus).
It's currently only available for Linux/MacOSX, since Windows
multiprocessing support is quite hacky in python2.6.
- a garbage collector was implemented to have better control over the memory
management. This part requires a long explanation, since it's related to OCC
Handle_* mechanism, built-in reference counting, as well as python reference
counting and object deletion. I plan to write a dedicated chapter on this
topic in the user's guide.
Best Regards,
Thomas
