A host of improvements in preparation for the 'bdist' command:
- added 'get_outputs()' method (all the other improvements were to support
this addition)
- made 'find_package_modules()' and 'find_modules()' return similar
values (list of (package, module, module_filename) tuples)
- factored 'find_all_modules()' out of 'get_source_files()' (needed
by 'get_outputs()')
- factored 'get_module_outfile()' out of 'build_module()' (also needed
by 'get_outputs()')
- various little tweaks, improvements, comment/doc updates
'--help-commands' option).
Shuffled imports around in a few command modules to avoid expensive
up-front import of sysconfig (and resulting delays in generating list
of all commands).
install) the setup script itself.
Fixed 'build_module()' so we do *not* preserve file mode (which means
we can install read-only files, which makes the next installation
of this distribution fail -- at least under Unix); added a comment
explaining this.
Bunch of little bug fixes that appeared in building non-packagized
distributions. Mainly:
- brain-slip typo in 'get_package_dir()'
- don't try to os.path.join() an empty path tuple -- it doesn't like it
- more type-safety in 'build_module()'
Don't call 'set_final_options()' in 'run()' anymore -- that's now
guaranteed to be taken care of for us by the Distribution instance.
Rearranged to bit to allow outsiders (specifically, the 'dist' command)
to find out what modules we would build:
- 'find_modules()' renamed to 'find_package_modules()'
- most of 'build_modules()' abstracted out to 'find_modules()'
- added 'get_source_files()' (for the 'dist' command to use)
- drastically simplified 'build_modules()' -- now just a wrapper around
'find_modules()' and 'build_module()'
of the 'install_py' command rather than 'build_py'. Obviously, this
meant that the 'build_py' and 'install_py' modules had to change; less
obviously, so did 'install' and 'build', since these higher-level
commands must make options available to control the lower-level
commands, and some compilation-related options had to migrate with the
code.
