Due to the presence of a "repodata/repomd.xml" path in a kickstart
repo, repo-autoindex previously interpreted kickstart repos as yum
repos. As such, a kickstart repo's index would solely consist of two
directories: "Packages" and "repodata".
While a kickstart repo does contain a yum repo, kickstart repos also
contain two additional repo entry points: treeinfo and extra_files.json.
Each entry point references additional files that should be included
in a kickstart repo's index. These files were previously ignored.
Now, when repo-autoindex encounters a kickstart repo, repo-autoindex
produces a repo index that reflects the content referenced in all
three repo entry points (repomd.xml, treeinfo, extra_files.json).
Redo the parsing of packages from primary.xml to use SAX; previously it
was using pulldom. The motivation for the change is to reduce memory usage.
When parsing a larger yum repo such as that contained within
rhel-8-for-ppc64le-appstream-kickstart__8_DOT_4, the observed memory
usage from repo-autoindex command was:
- pulldom: ~700MB
- SAX: ~85MB
This does not affect the output of the indexing process, and is covered
by existing tests.
Ultimately, all errors are propagated in some way, but it's important to
differentiate between "the content was invalid" vs "failed to fetch the
content".
