Comment:
Here are the steps I took:
1. Applied
[http://trac.sagemath.org/sage_trac/attachment/ticket/6503/trac_6503-scripts.patch
trac_6503-scripts.patch] to the scripts repository.
1. Applied
[http://trac.sagemath.org/sage_trac/attachment/ticket/6503/trac_6503-sage.patch
trac_6503-sage.patch] to the Sage library.
1. Removed `pyprocessing-0.52.p0.spkg` from the standard spkg repository.
1. Removed the following lines from `spkg/install`:
{{{
PYPROCESSING=`$newest pyprocessing`
export PYPROCESSING
}}}
1. Changed the following line in `spkg/standard/deps`
{{{
$(INST)/$(ZNPOLY) $(INST)/$(POLYTOPES_DB) $(INST)/$(PYPROCESSING)
$(INST)/$(GHMM) \
}}}
to this line
{{{
$(INST)/$(ZNPOLY) $(INST)/$(POLYTOPES_DB) $(INST)/$(GHMM) \
}}}
Removed the lines:
{{{
$(INST)/$(PYPROCESSING): $(BASE) $(INST)/$(PYTHON)
$(SAGE_SPKG) $(PYPROCESSING) 2>&1
}}}
Removed the line:
{{{
$(INST)/$(PYPROCESSING) \
}}}
The above steps were implemented against Sage 4.3.2.alpha0. Afterwards, I
packaged up this version of Sage but with pyprocessing removed as per the
above instructions. I then built this version of Sage from source, but
received the following error:
{{{

}}}
I also note that the file `devel/sage-main/setup.py` has these lines:
{{{
# If there were any extensions that needed to be
# rebuilt, dispatch them using pyprocessing.
if extensions_to_compile:
from processing import Pool
p = Pool(min(ncpus, len(extensions_to_compile)))
}}}
from line 320. It uses the pyprocessing spkg, when in fact this spkg has
been removed as per the proposal of this ticket. Perhaps this could be a
reason for the above build error I received. A fix is to change the above
lines to use multiprocessing instead of processing. I'm investigating this
approach, in addition to John's patches.
