Bugfix: mirroring will fail if no matched files found

v0.13.4

Bump version to 0.13.4

Bugfix: mirroring can fail for some packages

When filtering files of a package to mirror, Morgan checks whether the file's required Python version matches all environments. If a package defines its required version as a simple number instead of an actual specifier (e.g. '3' instead of the correct '==3'), then Morgan would fail when determining whether the file should be downloaded.

This release fixes the issue by forcing such files to have a valid specifier, and also ignoring files that still fail Morgan's verification.

Bugfix: downloaded files may not match all environments

When Morgan mirrors packages, it chooses the most recent version that satisfies the requirement strings, and the environments. However, when matching environments, it would select files (and therefore version) that matches at least one of the Python versions of the environments, which could lead to Morgan choosing versions that do not support all of the Python versions.

This commit fixes this bug by requiring the selected versions match ALL of the Python versions defined in the environments. This could potentially lead to Morgan not finding matches at all, but this would be fixed in a subsequent release by treating each environment independently of the others.

Support any 1.x metadata version when mirroring

This release updates Morgan's mirroring code to support any package metadata version in the 1.x family, not just 1.0.

Allow disabling serving of metadata files

The server will now accept a --no-metadata flag, which will disable serving of metadata files
when provided. This can be useful if installing packages via pip but not providing normalized
names (e.g. pip install FastAPI instead of pip install fastapi). This is to workaround an issue
with pip: when it is provided a non-normalized name, it sends it to the server normalized, but
expects the metadata file returned to have the non-normalized name. However, the server
cannot know what the non-normalized name is. The only way to work around this is to disable
serving of metadata files altogether.

Bugifx: decode request URLs before handling

This release fixes a server issue with package distribution files that contain characters
that must be encoded in order to work inside a URL. The server will now properly
unescape the URL so such files can be downloaded.

Thanks to Imran Hossain for this release.

Fix pkg name retrieval in generate_reqs

This version fixes the AttributeError: 'PathDistribution' object has no attribute 'name'
that may happen when running command morgan generate_reqs.

Thanks to Nikolai Gaiduchenko for this release.

Bugfix: manylinux wheels not downloaded

Wheels marked as "manylinux" or "musllinux" were not downloaded to a typo in the relevant regular expression.

Thanks to Imran Hossain for this fix.

Move to Hatch, add metadata

The project no longer uses Poetry for a project manager, and now uses
Hatch >=1.5.0. This allows the project to define metadata in
pyproject.toml in a standard way.

A lot of metadata is introduced. The version is no longer statically
defined in pyproject.toml, but dynamically defined in
morgan/about.py (variable version). A "version" command is added
to the Morgan command line, which simply prints the version and exits.

Bugfix: some setuptools dependencies may be missed

Some dependencies define in a setuptools' requirements.txt file can be
missed and not mirrored if their are conditional on both an extra and
environment marker specifications.
