    • Refactor cache refreshing/expiring · ffb9b3ef
      Yorick Peterse authored 
      This refactors repository caching so it's possible to selectively
refresh certain caches, instead of just expiring and refreshing
everything.

To allow this the various methods that were cached (e.g. "tag_count" and
"readme") use a similar pattern that makes expiring and refreshing
their data much easier.

In this new setup caches are refreshed as follows:

1. After a commit (but before running ProjectCacheWorker) we expire some
   basic caches such as the commit count and repository size.

2. ProjectCacheWorker will recalculate the commit count, repository
   size, then refresh a specific set of caches based on the list of
   files changed in a push payload.

This requires a bunch of changes to the various methods that may be
cached. For one, data should not be cached if a branch used or the
entire repository does not exist. To prevent all these methods from
handling this manually this is taken care of in
Repository#cache_method_output. Some methods still manually check for
the existence of a repository but this result is also cached.

With selective flushing implemented ProjectCacheWorker no longer uses an
exclusive lease for all of its work. Instead this worker only uses a
lease to limit the number of times the repository size is updated as
this is a fairly expensive operation.
    • Use File.exist? to check if a repository exists · 6f393877
      Yorick Peterse authored 
      Initializing Rugged objects is way too expensive just to check if a
repository exists. Even though we cache this data once in a while we
have to refresh this. On GitLab.com we have seen Repository#exists?
taking up to _1 minute_ to complete in the absolute worst case, though
usually it sits around a second or so.

Using File.exist? to instead check if $GIT_DIR/refs exists is a much
faster way of checking if a repository was initialized properly.
    • Unify detecting of special repository files · df5548e1
      Yorick Peterse authored 
      This moves the logic of detecting special repository files (e.g. a
README or a Koding configuration file) to a single class:
Gitlab::FileDetector. Moving this logic into a single place allows this
to be re-used more easily.

This commit also changes Repository#gitlab_ci_yaml so that its cached
similar to other data (e.g. the Koding configuration file).
