15 years agoclone: disconnect transport after fetching
Jeff King [Wed, 2 Sep 2009 06:36:47 +0000 (02:36 -0400)]
clone: disconnect transport after fetching

The current code just leaves the transport in whatever state
it was in after performing the fetch.  For a non-empty clone
over the git protocol, the transport code already
disconnects at the end of the fetch.

But for an empty clone, we leave the connection hanging, and
eventually close the socket when clone exits. This causes
the remote upload-pack to complain "the remote end hung up
unexpectedly". While this message is harmless to the clone
itself, it is unnecessarily scary for a user to see and may
pollute git-daemon logs.

This patch just explicitly calls disconnect after we are
done with the remote end, which sends a flush packet to
upload-pack and cleanly disconnects, avoiding the error
message.

Other transports are unaffected or slightly improved:

 - for a non-empty repo over the git protocol, the second
   disconnect is a no-op (since we are no longer connected)

 - for "walker" transports (like HTTP or FTP), we actually
   free some used memory (which previously just sat until
   the clone process exits)

 - for "rsync", disconnect is always a no-op anyway

The effects of repacking on a repository with alternates are a bit
subtle. The two main things users will want are:

  1. Not to waste disk space by accidentally copying objects which could
     be shared.

  2. Copying all objects explicitly to break the dependency on the source
     repo.

This patch describes both under the "clone -s" documentation. It makes
sense to put it there rather than in git-repack.txt for both cases.

For (1), we are warning the user who is using "clone -s" about what _not_
to do, so we need to get their attention when reading about "clone -s".

For (2), we are telling them how git-repack can be used to accomplish a
task, but until they know that git-repack is the right tool, they have no

and often do begin with any valid RFC2822 header lines.

the value is not quoted. This is already documented in git-config(1), but

merge-recursive: don't segfault while handling rename clashes

When a branch moves A to B while the other branch created B (or moved C to
B), the code tried to rename one of them to B~something to preserve both
versions, and failed to register temporary resolution for the original
path B at stage#0 during virtual ancestor computation.  This left the
index in unmerged state and caused a segfault.

A better solution is to merge these two versions of B's in place and use
the (potentially conflicting) result as the intermediate merge result in
the virtual ancestor.

Demonstrate bugs when a directory is replaced with a symlink

This test creates two directories, a/b and a/b-2, then replaces a/b with
a symlink to a/b-2, then merges that change into the 'baseline' commit,
which contains an unrelated change.

There are two bugs:
1. 'git checkout' incorrectly deletes work tree file a/b-2/d.
2. 'git merge' incorrectly deletes work tree file a/b-2/d.

The test goes on to create another branch in which a/b-2 is replaced
with a symlink to a/b (i.e., the reverse of what was done the first
time), and merge it into the 'baseline' commit.

There is a different bug:
3. The merge should be clean, but git reports a conflict.
