Since the message advises to fix the configuration first, the
advantage of using this command is that it is cut-and-paste ready,
while using --author='...' requires the user to type his name and
email again.

When determine_author_info() returns to the calling prepare_to_commit(),
we already know the pieces of information necessary to determine what
author ident will be used in the final message, but deferred making a call
to fmt_ident() before the final commit_tree(). Most importantly, we would
open the editor to ask the user to compose the log message before it.
As one important side effect of fmt_ident() is to error out when the given
information is malformed, this resulted in us spawning the editor first
and then refusing to commit due to error, even though we had enough
information to detect the error before starting the editor, which was
annoying.
Move the fmt_ident() call to the end of determine_author_info() where we
have final determination of author info to rectify this.

Now that struct commit.util is not used until after we've checked that
the argument doesn't exactly match a tag, we can wait until then to
look up the commits for each tag.
This avoids a lot of I/O on --exact-match queries in repositories with
many tags. For example, 'git describe --exact-match HEAD' becomes
about 12 times faster on a cold cache (3.2s instead of 39s) in a
linux-2.6 repository with 2000 packed tags. That is a huge win for the
interactivity of the __git_ps1 shell prompt helper when on a detached
HEAD.

describe is currently forced to look up the commit at each tag in
order to store the struct commit_name pointers in struct commit.util.
For --exact-match queries, those lookups are wasteful. In preparation
for removing them, put the commit_names into a hash table, indexed by
commit SHA1, that can be used to quickly check for exact matches.

In case HEAD does not point to a valid commit yet, merge is
implemented as a hard reset. This will cause untracked files to be
overwritten.
Instead, assume the empty tree for HEAD and do a regular merge. An
untracked file will cause the merge to abort and do nothing. If no
conflicting files are present, the merge will have the same effect
as a hard reset.

Some patches have a timezone formatted like '-08:00' instead of
'-0800' in their ---/+++ lines (e.g. http://lwn.net/Articles/131729/).
Take this into account when searching for the start of the timezone
(which is the end of the filename).
This does not actually affect the outcome of patching unless (1) a
file being patched has a non-' ' whitespace character (e.g., tab) in
its filename, or (2) the patch is whitespace-damaged, so the tab
between filename and timestamp has been replaced with spaces.

Usually when applying a binary diff generated without
--binary, it will be rejected early, as we don't even have
the full sha1 of the pre- and post-images.
However, if the diff is generated with --full-index (but not
--binary), then we will actually try to apply it. If we have
the postimage blob, then we can take a shortcut and never
even look at the binary diff at all (e.g., this can happen
when rebasing changes within a repository).
If we don't have the postimage blob, though, we try to look
at the actual fragments, of which there are none, and get a
segfault. This patch checks explicitly for that case and
complains to the user instead of segfaulting. We need to
keep the check at a low level so that the "shortcut" case
above continues to work.
We also add a test that demonstrates the segfault. While
we're at it, let's also explicitly test the shortcut case.

Right now, packing valid objects could fail when creating a thin pack
simply because a pack edge object used as a preferred base is corrupted.
Since preferred base objects are not strictly needed to produce a valid
pack, let's not consider the inability to read them as a fatal error.
Delta compression may well be attempted against other objects in the
search window. To avoid warning storms (we are in the inner loop of
the delta search window) a warning is emitted only on the first
occurrence.

Saying "pack-objects died with strange error" after "pack-objects died
of signal 13" seems kind of redundant. The latter message was
introduced when the run-command API changed to report abnormal exits
on behalf of the caller (v1.6.5-rc0~86^2~5, 2009-07-04).
Similarly, after a controlled pack-objects failure (detectable as a
normal exit with nonzero status), a "died with strange error" message
would be redundant next to the message from pack-objects itself.
So leave off the "strange error" messages.
The result should look something like this:
$ git push sf master
Counting objects: 21542, done.
Compressing objects: 100% (4179/4179), done.
fatal: Unable to create temporary file: Permission denied
error: pack-objects died of signal 13
error: failed to push some refs to 'ssh://sf.net/gitroot/project/project'
$
Or in the "controlled exit" case (contrived example):
[...]
fatal: delta size changed
error: failed to push some refs to 'ssh://example.com/foo/bar'

Since b541248 (merge.conflictstyle: choose between "merge" and "diff3
-m" styles, 2008-08-29), git-merge-file uses setup_directory_gently(),
thus cd'ing around to find any possible config files to use.
This broke merge-file when it is called from within a subdirectory of
a repository, and the arguments are all relative paths.
Fix by prepending the prefix, as passed down from the main git
setup code, if there is any.

The code paths for showing commits in "git log" and "git
rev-list --graph" correctly handle embedded NULs by looking
only at the resulting strbuf's length, and never treating it
as a C string. The code path for regular rev-list, however,
used printf("%s"), which resulted in truncated output. This
patch uses fwrite instead, like the --graph code path.

Some patches have a timezone formatted like ‘-08:00’ instead of
‘-0800’ (e.g. http://lwn.net/Articles/131729/), so git apply would

create empty files instead. Teach it to support both formats, and add

cherry-pick will segfault when transplanting a root commit if the --ff
option is used. This happens because the "parent" pointer is set to NULL
when the commit being cherry-picked has no parents. Later, when "parent"
is dereferenced, the cherry-pick segfaults.
Fix this by checking whether "parent" is NULL before dereferencing it and
add a test for this case of cherry-picking a root commit with --ff.
