In get_sha1_basic, we parse a string like
HEAD@{10 seconds ago}:path/to/file
into its constituent ref, reflog date, and path components.
We never actually munge the string itself, but instead keep
offsets into the string with their associated lengths.
When we call approxidate on the contents inside braces,
however, we pass just a string without a length. This means
that approxidate could sometimes look past the closing brace
and (erroneously) interpret the rest of the string as part
of the date.

Since git-remote always uses remote tracking branches, it
should be safe to always force updates of those branches.
I.e., we should generate
fetch = +refs/heads/*:refs/remotes/$remote/*
instead of
fetch = refs/heads/*:refs/remotes/$remote/*
This was the behavior of the perl version, which seems to
have been lost in the C rewrite.

Previously, a push like:
git push remote src:dst
would go through the following steps:
1. check for an unambiguous 'dst' on the remote; if it
exists, then push to that ref
2. otherwise, check if 'dst' begins with 'refs/'; if it
does, create a new ref
3. otherwise, complain because we don't know where in the
refs hierarchy to put 'dst'
However, in some cases, we can guess about the ref type of
'dst' based on the ref type of 'src'. Specifically, before
complaining we now check:
2.5. if 'src' resolves to a ref starting with refs/heads
or refs/tags, then prepend that to 'dst'
So now this creates a new branch on the remote, whereas it
previously failed with an error message:
git push master:newbranch
Note that, by design, we limit this DWIM behavior only to
source refs which resolve exactly (including symrefs which
resolve to existing refs). We still complain on a partial
destination refspec if the source is a raw sha1, or a ref
expression such as 'master~10'.

This test tried to push into a remote with ambiguous refs in

never actually tells us about the refs/remotes hierarchy, so
we don't even see this ambiguity.
The test happened to pass because we were simply looking for
failure, and the test fails for another reason: the dst
refspec does not exist and does not begin with refs/, making
it invalid.

Tunnel = "ssh -q user@server.com /usr/bin/imapd ./Maildir 2> /dev/null"

However, git-imap-send currently requires that the imap.host variable be
set in the config even when it was unused. This patch changes imap-send
to only require that the imap.host setting is set if imap.tunnel is not
set. Otherwise, server.host is set to "tunnel" for reporting purposes.

When asked for history of a file which is not present in given branch
("HEAD", i.e. current branch, or given by transient $hash_hase ('hb')
parameter), but is present deeper in the history (meaning that "git
rev-list --full-history $hash_base -- $file_name" is not empty), and
there is no $hash ('h') parameter set for a file, gitweb would spew
multiple of "Use of uninitialized value" warnings, and some links
would be missing. This commit fixes this bug.
This bug occurs in the rare cases when "git log -- <path>" is empty
and "git log --full-history -- <path>" is not, or to be more exact in
the cases when full-history starts later than given branch. It can
happen if you are using handcrafted gitwb URL, or if you follow
generic 'history' link or bookmark for a file which got deleted.
Gitweb tried to get file type ('tree', or 'blob', or even 'commit')
from the commit we start searching from (where the file was not
present), and not among found commits. This was the cause of "Use of
uninitialized value" warnings.
This commit also add tests for such situation to t9500 test.
While we are it, return HTTP error if there is _no_ history; it means
that file or directory was not found (for given branch). Also error
out if type of item could not be found: it should not happen now, but
better be sure.

Traditionally git-rebase was implemented in terms of "format-patch" piped
to "am -3", to strike balance between speed (because it avoids a rather
expensive read-tree/merge-recursive machinery most of the time) and
flexibility (the magic "-3" allows it to fall back to 3-way merge as
necessary). However, this combination has one flaw when dealing with a
nonstandard commit log message format that has more than one lines in the
first paragraph.
This teaches "git am --rebasing" to take advantage of the fact that the
mbox message "git rebase" prepares for it records the original commit
object name, to get the log message from the original commit object
instead.

bisect: squelch "fatal: ref HEAD not a symref" misleading message

Before this patch, when "git bisect start", "git bisect good" or
"git bisect skip" were called with many revisions, they could fail
after having already marked some revisions as "good", "bad" or
"skip".
This could be especilally bad for "git bisect start" because as
the file ".git/BISECT_NAMES" would not have been written, there
would have been no attempt to clear the marked revisions on a
"git bisect reset". That's because if there is no
".git/BISECT_NAMES" file, nothing is done to clean things up, as
the bisect session is not supposed to have started.
While at it, let's also create the ".git/BISECT_START" file, only
after ".git/BISECT_NAMES" as been created.

When the Subject: line is empty for whatever reason, git-am was fooled by
it and left an empty line at the beginning of the resulting commit log
message.
This moves the logic around so that we do not keep $SUBJECT in a separate
variable. Instead, $dotest/msg-clean, which used to be the log message
body extracted from the message and then trailing whitespaces cleansed
out, now contains the subject line followed by a blank line at the
beginning for normal messages, and we use the first line from the file as
the summary line throughout the program.

To get the current HEAD when we start bisecting using for example
"git bisect start", we first try "git symbolic-ref HEAD" to get a
nice name, and if it fails, we fall back to "git rev-parse
--verify HEAD".
The problem is that when "git symbolic-ref HEAD" fails, it
displays "fatal: ref HEAD not a symref", so it looks like "git
bisect start" failed and does not accept detached HEAD, even if
in fact it worked fine.

For SSH clients restricted to git-shell, CVS_SERVER does not have to be

mean git-cvsserver'. This makes it totally transparent to CVS users, but
the instruction to set up CVS access for people with real shell access
does not apply.
Previous wording mentioning GIT_AUTHOR, GIT_COMMITTER variables was
unclear that we really meant GIT_AUTHOR_(NAME|EMAIL), etc.
Note that the .ssh/environment file is a good place to set these, and that
