Running with regrtest does not show spurious output or unrestored
sys.std* objects; sometimes running with make test is different, I’ll
watch the buildbots.
In addition, update the create module to use logging.
The code I fixed to comply with PEP 3147 still had one bug: When run
under python -O, some paths for pyc files would be pyo, because I called
imp.cache_from_source without explicit debug_override argument in some
places, and under -O that would return .pyo (this is well explained in
the imp docs). Now all code (util.byte_compile, build_py, install_lib)
can create .pyo files according to options given by users,
without interference from the calling Python’s own optimize mode.
On a related topic, I also removed the code that prevented byte
compilation under python -B. The rationale is that packaging gives
control over the creation of pyc files to the user with its own explicit
option, and the behavior should not be changed if the calling Python
happens to run with -B for whatever reason. I will argue that this is a
bug fix and ask to be allowed to backport this change to distutils.
Finally, I moved one nugget of information about the --compile and
--optimize options from the source into the doc. It clears up a
misunderstanding that I (and maybe other people) had.
I’ve made more edits than the bug report suggested to make sure the
generated setup script is compatible with many Python versions; a
comment in the source explains that in detail.
The cfg_to_args function uses old 2.x idioms like codecs.open and
RawConfigParser.readfp because I want the setup.py generated by packaging and
distutils2 to be the same. Most users won’t see the deprecation warning and I
ignore it in the test suite.
Thanks to David Barnett for the report and original patch.
- Use os.makedirs (I had forgotten about it!)
- Let TempdirManager.write_file call os.path.join for us
- Remove custom command added by test_dist
- Use a skip instead of hiding a method with an underscore
- Address pyflakes warnings
PEP 370 features and sys.dont_write_bytecode are always available
in 3.3; the distutils2 backport still has the conditionals.
I also renamed an internal misnamed method and fixed a few things
(“packaging2” name, stray print, unused import, fd leak).
This huge module is the heir of six distutils modules, and contains
a number of miscellaneous functions. I have attempted to help readers
of the source code with an annoted __all__. Removed or deprecated
functions have been removed from the documentation; I’m working on
another patch to document the remaining public functions.
For the curious:
The unzip_file and untar_file were used by (or intended to be used by)
“pysetup install path/to/archive.tar.gz”, but the code presently used
shutil.unpack_archive and an helper function, so I just deleted them.
They’re still in the repository if we need them in the future.
The find_packages function is not used anymore but I want to discuss
module and package auto-discovery (in “pysetup create”) again before
removing it.
subst_vars now lives in sysconfig; rfc822_escape is inlined in
packaging.metadata. Other functions are for internal use only, or
deprecated; I have left them out of __all__ and sprinkled TODO notes
for future cleanups.
This change also makes sure the logger handlers are not alterated after an
installation. That also fixes the remaining environment alteration issue in
test_packaging.
