Please reconsider how subversion works. It has the notion of atomic
commits, so you either get the entire change, or none at all.

Fortunately, the buildbot keeps logs of everything it does:

http://www.python.org/dev/buildbot/trunk/g4%20osx.4%20trunk/builds/1449/step-svn/0

shows

U    Lib/test/test_itertools.py
U    Modules/itertoolsmodule.c
Updated to revision 51950.

So it said it updated both files. But perhaps it didn't build them?
Let's check:


http://www.python.org/dev/buildbot/trunk/g4%20osx.4%20trunk/builds/1449/step-compile/0

has this:

building 'itertools' extension

gcc -fno-strict-aliasing -Wno-long-double -no-cpp-precomp
-mno-fused-madd -g -Wall -Wstrict-prototypes -I.
-I/Users/buildslave/bb/trunk.psf-g4/build/./Include
-I/Users/buildslave/bb/trunk.psf-g4/build/./Mac/Include -I./Include -I.
-I/usr/local/include -I/Users/buildslave/bb/trunk.psf-g4/build/Include

build/temp.macosx-10.3-ppc-2.6/Users/buildslave/bb/trunk.psf-g4/build/Modules/itertoolsmodule.o

gcc -bundle -undefined dynamic_lookup
build/temp.macosx-10.3-ppc-2.6/Users/buildslave/bb/trunk.psf-g4/build/Modules/itertoolsmodule.o
-L/usr/local/lib -o build/lib.macosx-10.3-ppc-2.6/itertools.so

So itertools.so is regenerated, as it should; qed.
