fastestmirror: move the logic before MD retrieval. BZ 1428210
|
|
|
911d2c |
|
|
|
911d2c |
This plugin has had no effect on metadata downloads since commit a522869
|
|
|
911d2c |
in yum where we put a RepoStorage.retrieveAllMD() call before
|
|
|
911d2c |
postreposetup_hook used by this plugin. Let's change to using
|
|
|
911d2c |
prereposetup_hook instead so that retrieveAllMD() can make use of the
|
|
|
911d2c |
sorted urls.
|
|
|
911d2c |
|
|
|
911d2c |
In practice, though, mirrors would still be benchmarked and sorted
|
|
|
911d2c |
because of a similar mechanism present in urlgrabber (the timedhosts
|
|
|
911d2c |
option, always enabled in yum) with one exception: If the yum cache is
|
|
|
911d2c |
empty (no timedhosts file yet), the original order received from the
|
|
|
911d2c |
server would be retained (a property of stable sorting [1]) for the
|
|
|
911d2c |
repomd.xml download, which is still a bad situation that wouldn't happen
|
|
|
911d2c |
before a522869; this is fixed with this commit as it allows the plugin
|
|
|
911d2c |
to do its work beforehand.
|
|
|
911d2c |
|
|
|
911d2c |
Note that the stuff we do in yum/repos.py in between prereposetup_hook
|
|
|
911d2c |
and postreposetup_hook has nothing to do with our plugin anyway, so we
|
|
|
911d2c |
won't "miss" or break any configuration steps when we move our logic
|
|
|
911d2c |
from the latter to the former location.
