3 years agorefs: cleanup directories when deleting packed ref
Will Chandler [Sat, 8 May 2021 05:00:43 +0000 (01:00 -0400)] 
refs: cleanup directories when deleting packed ref

When deleting a packed ref via 'update-ref -d', a lockfile is made in
the directory that would contain the loose copy of that ref, creating
any directories in the ref's path that do not exist. When the
transaction completes, the lockfile is deleted, but any empty parent
directories made when creating the lockfile are left in place.  These
empty directories are not removed by 'pack-refs' or other housekeeping
tasks and will accumulate over time.

When deleting a loose ref, we remove all empty parent directories at the
end of the transaction.

This commit applies the parent directory cleanup logic used when
deleting loose refs to packed refs as well.

clean: remove unnecessary variable

The variable `matches` used to hold the return of a `dir_path_match()`
call that was removed in 95c11ecc73 ("Fix error-prone fill_directory()
API; make it only return matches", 2020-04-01). Now `matches` will
always hold 0, which is the value it's initialized with; and the
condition `matches != MATCHED_EXACTLY` will always evaluate to true. So
let's remove this unnecessary variable.

Interestingly, it seems that `matches != MATCHED_EXACTLY` was already
unnecessary before 95c11ecc73. That's because `remove_directories` is
always set to 1 when we have pathspecs; So, in the condition
`!remove_directories && matches != MATCHED_EXACTLY`, we would either:

- have pathspecs (or have been given `-d`) and ignore `matches` because
  `remove_directories` is 1; or

- not have pathspecs (nor `-d`) and end up just checking that
  `0 != MATCHED_EXACTLY`, as `matches` would never get reassigned
  after its zero initialization (because there is no pathspec to match).

git-p4: speed up search for branch parent

For every new branch that git-p4 imports, it needs to find the commit
where it branched off its parent branch. While p4 doesn't record this
information explicitly, the first changelist on a branch is usually an
identical copy of the parent branch.

The method searchParent() tries to find a commit in the history of the
given "parent" branch whose tree exactly matches the initial changelist
of the new branch, "target". The code iterates through the parent
commits and compares each of them to this initial changelist using
diff-tree.

Since we already know the tree object name we are looking for, spawning
diff-tree for each commit is wasteful.

Use the "--format" option of "rev-list" to find out the tree object name
of each commit in the history, and find the tree whose name is exactly
the same as the tree of the target commit to optimize this.

This results in a considerable speed-up, at least on Windows. On one
Windows machine with a fairly large repository of about 16000 commits in
the parent branch, the current code takes over 7 minutes, while the new
code only takes just over 10 seconds for the same changelist:

Before:
