"""Extract metadata from filenames.
|
|
|
|
Extracts the 4 metadataitems needed (name, version, pyversion, arch) from
|
|
the installer filename and the name of the egg-info directory embedded in
|
|
the zipfile (if any).
|
|
|
|
The egginfo filename has the format::
|
|
|
|
name-ver(-pyver)(-arch).egg-info
|
|
|
|
The installer filename has the format::
|
|
|
|
name-ver.arch(-pyver).exe
|
|
|
|
Some things to note:
|
|
|
|
1. The installer filename is not definitive. An installer can be renamed
|
|
and work perfectly well as an installer. So more reliable data should
|
|
be used whenever possible.
|
|
2. The egg-info data should be preferred for the name and version, because
|
|
these come straight from the distutils metadata, and are mandatory.
|
|
3. The pyver from the egg-info data should be ignored, as it is
|
|
constructed from the version of Python used to build the installer,
|
|
which is irrelevant - the installer filename is correct here (even to
|
|
the point that when it's not there, any version is implied).
|
|
4. The architecture must be taken from the installer filename, as it is
|
|
not included in the egg-info data.
|
|
5. Architecture-neutral installers still have an architecture because the
|
|
installer format itself (being executable) is architecture-specific. We
|
|
should therefore ignore the architecture if the content is pure-python.
