[RFC] _chunks_to_lines_pyx rebuild problem

[Martin Pool]

2009/5/28 Alexander Belchenko <bialix at ukr.net>:
> C extension _chunk_to_lines_pyx is imported by osutils.py. This import effectively preventing to delete compiled extension while all extensions rebuilding on Windows, because osutils is used by setup.py.

This is understandable but may be surprising to unix developers; maybe
you should put a note in osutils.py about this.

It seems, it's only present in osutils to give it a standard name that
saves callers from needing to work out whether to load the pyx or py
version.  It would be a shame to replicate the
try:import:except:import everywhere, but you can certainly move it to
some other location.

In most cases we have say bzrlib.rio loading _rio_pyx.  Possibly we
need stringutils or something more specific than osutils.

Alternatively perhaps what setup.py needs should be moved out of osutils.
