Comment #3 on issue 1226 by reinhold.kainhofer: lilypond-book in the MinGW
release is currently unusable (2.13.30?)
http://code.google.com/p/lilypond/issues/detail?id=1226
The filter_pipe function used os.popen3, which according to the python
documentation has been deprecated since python 2.6:
http://docs.python.org/library/os.html
The suggested replacement is subprocess.Popen, see also
http://docs.python.org/release/2.4/lib/node238.html and
http://docs.python.org/release/2.4/lib/module-subprocess.html. In windows,
the subprocess module needs the msvcrt python module, which is part of the
python standard lib since 2.4:
http://docs.python.org/release/2.4/lib/module-msvcrt.html
Unfortunately, it seems that in GUB, python is not built with that python
module, so of course the subprocess module refuses to laod.
I have now reverted the filter_pipe function to use the deprecated
os.popen3. However, if we ever resolve the subprocess/msvcrt issue in
Windows, we should replace all those deprecated functions by the
proper "new" functions....
