fedora-mirror.py

A tool for synchronizing a local mirror of fedora rpms.


Goals:

  • Being able to cleanly maintain a local mirror for fedora packages.
  • Zero config as far as possible


Status:

  • Using reposync as backend
  • Basics are working


Todo:

Code:

  • ConfigParser
  • logging
  • legacy and updates-testing awareness
  • fix hierachy into the fedora mirror dir scheme
  • use separate configs for each release
  • progressbars
  • eta (complete, per repo, per file(?!))
  • more exceptions


Support files/packaging/integration:

  • creation of specially crafted .repo files
  • cron integration
  • 0 conf apache serving as split package
  • mock config files as split package
  • yum localmirror config files as split package
  • discuss access rights on /srv/mirror

<!--# special cases:
-->
<!--# - the fedora core repos differ in logic -> core repos have updates, updates-testing, legacy -> to be investigated
-->
<!--# - development is another special case not having updates updates-testing and legacy
-->
<!--# - other repos (3rd party) never have updates and updates-testing
-->
<!--# - SRPMS are another special case -> same for each arch of the same release
