After you find out an earlier resolution you told rerere to use was a
mismerge, there is no easy way to clear it. A new subcommand "forget" can
be used to tell git to forget a recorded resolution, so that you can redo
the merge from scratch.
rerere: refactor rerere logic to make it independent from I/O
This splits the handle_file() function into in-core part and I/O
parts of the logic to create the preimage, so that we can compute
the conflict identifier without having to use temporary files.
Earlier, I thought the output from handle_file() should also be
refactored, but it is always about writing preimage (or thisimage)
that is used for later three-way merge, so it is saner to keep it
to always write to FILE *.
Previously, failures during execvp could be detected only by
finish_command. However, in some situations it is beneficial for the

start_command: report child process setup errors to the parent's stderr
When the child process's environment is set up in start_command(), error
messages were written to wherever the parent redirected the child's stderr
channel. However, even if the parent redirected the child's stderr, errors
during this setup process, including the exec itself, are usually an
indication of a problem in the parent's environment. Therefore, the error
messages should go to the parent's stderr.
Redirection of the child's error messages is usually only used to redirect
hook error messages during client-server exchanges. In these cases, hook
setup errors could be regarded as information leak.
This patch makes a copy of stderr if necessary and uses a special
die routine that is used for all die() calls in the child that sends the
errors messages to the parent's stderr.
The trace call that reported a failed execvp is removed (because it writes
to stderr) and replaced by die_errno() with special treatment of ENOENT.
The improvement in the error message can be seen with this sequence:
mkdir .git/hooks/pre-commit
git commit
Previously, the error message was
error: cannot run .git/hooks/pre-commit: No such file or directory
ident.c: treat $EMAIL as giving user.email identity explicitly
The environment variable EMAIL has been honored since 28a94f8 (Fall back

2007-04-28) as the end-user's wish to use the address as the identity.
When we use it, we should say we are explicitly given email by the user.
ident.c: check explicit identity for name and email separately
bb1ae3f (commit: Show committer if automatic, 2008-05-04) added a logic to
check both name and email were given explicitly by the end user, but it
assumed that fmt_ident() is never called before git_default_user_config()
is called, which was fragile. The former calls setup_ident() and fills
the "default" name and email, so the check in the config parser would have
mistakenly said both are given even if only user.name was provided.
Make the logic more robust by keeping track of name and email separately.

Commit 9e8ecea (Add 'merge' mode to 'git reset', 2008-12-01) disallowed
"git reset --merge" when there was unmerged entries. But it wished if
unmerged entries were reset as if --hard (instead of --merge) has been
used. This makes sense because all "mergy" operations makes sure that
any path involved in the merge does not have local modifications before
starting, so resetting such a path away won't lose any information.
The previous commit changed the behavior of --merge to accept resetting
unmerged entries if they are reset to a different state than HEAD, but it
did not reset the changes in the work tree, leaving the conflict markers
in the resulting file in the work tree.
Fix it by doing three things:
- Update the documentation to match the wish of original "reset --merge"
better, namely, "An unmerged entry is a sign that the path didn't have
any local modification and can be safely resetted to whatever the new
HEAD records";
- Update read_index_unmerged(), which reads the index file into the cache
while dropping any higher-stage entries down to stage #0, not to copy
the object name from the higher stage entry. The code used to take the
object name from the a stage entry ("base" if you happened to have
stage #1, or "ours" if both sides added, etc.), which essentially meant
that you are getting random results depending on what the merge did.
The _only_ reason we want to keep a previously unmerged entry in the
index at stage #0 is so that we don't forget the fact that we have
corresponding file in the work tree in order to be able to remove it
when the tree we are resetting to does not have the path. In order to
differentiate such an entry from ordinary cache entry, the cache entry
added by read_index_unmerged() is marked as CE_CONFLICTED.
- Update merged_entry() and deleted_entry() so that they pay attention to
cache entries marked as CE_CONFLICTED. They are previously unmerged
entries, and the files in the work tree that correspond to them are
resetted away by oneway_merge() to the version from the tree we are
resetting to.
reset: use "unpack_trees()" directly instead of "git read-tree"
This patch makes "reset_index_file()" call "unpack_trees()" directly
instead of forking and execing "git read-tree". So the code is more
efficient.
And it's also easier to see which unpack_tree() options will be used,
as we don't need to follow "git read-tree"'s command line parsing
which is quite complex.
As Daniel Barkalow found, there is a difference between this new
version and the old one. The old version gives an error for
"git reset --merge" with unmerged entries, and the new version does
not when we reset the entries to some states that differ from HEAD.
Instead, it resets the index entry and succeeds, while leaving the
conflict markers in the corresponding file in the work tree (which
will be corrected by the next patch).

git-difftool: Add '--gui' for selecting a GUI tool
Users might prefer to have git-difftool use a different
tool when run from a Git GUI.
This teaches git-difftool to honor 'diff.guitool' when
the '--gui' option is specified. This allows users to
configure their preferred command-line diff tool in
'diff.tool' and a GUI diff tool in 'diff.guitool'.

If a difftool test has an error then running the git test suite
may end up invoking a GUI diff tool. We now guard against this
by setting a difftool.bogus-tool.cmd variable.
The tests already used --tool=bogus-tool in various places so
this is simply ensuring that nothing ever falls back and
finds a real diff tool.
