Rewrite Tcl/Tk interpreter path for the GUI tools.
--with-tcltk=/path/to/wish sets the TCLTK_PATH variable that is
used to substitute the location of the wish interpreter in the
Tcl/Tk programs.
New tracking file, GIT-GUI-VARS, was introduced: it tracks the
location of the Tcl/Tk interpreter and activates the GUI tools
rebuild if the interpreter path was changed. The separate tracker
is better than the GIT-CFLAGS: there is no need to rebuild the whole
git if the interpreter path was changed.

contrib/workdir: add a simple script to create a working directory
Add a simple script to create a working directory that uses symlinks
to point at an exisiting repository. This allows having different
branches in different working directories but all from the same
repository.
Based on a description from Junio of how he creates multiple working
directories[1]. With the following caveat:
"This risks confusion for an uninitiated if you update a ref that
is checked out in another working tree, but modulo that caveat
it works reasonably well."
Reimplement emailing part of hooks--update in contrib/hooks/post-receive-email
The update hook is no longer the correct place to generate emails; there
is now the hooks/post-receive script which is run automatically after a
ref has been updated.
This patch is to make use of that new location, and to address some
faults in the old update hook.
The primary problem in the conversion was that in the update hook, the
ref has not actually been changed, but is about to be. In the
post-receive hook the ref has already been updated. That meant that
where we previously had lines like:
git rev-list --not --all
would now give the wrong list because "--all" in the post-receive hook
includes the ref that we are making the email for. This made it more
difficult to show only the new revisions added by this update.
The solution is not pretty; however it does work and doesn't need any
changes to git-rev-list itself. It also fixes (more accurately: reduces
the likelihood of) a nasty race when another update occurs while this
script is running. The solution, in short, looks like this (see the
source code for a longer explanation)
This uses git-rev-parse followed by grep to filter out the revision of
the ref in question before it gets to rev-list and inhibits the output
of itself. By using $(git rev-parse $revname) rather than $newrev as the
filter, it also takes care of the situation where another update to the
same ref has been made since $refname was $newrev.
The second problem that is addressed is that of tags inhibiting the
correct output of an update email. Consider this, with somebranch and
sometag pointing at the same revision:
That would work fine; the push of the branch would generate an email
containing all the new commits introduced by the update, then the push
of the tag would generate the shortlog formatted tag email. Now
consider:
When some branch comes to run its "--not --all" line, it will find
sometag, and filter those commits from the email - leaving nothing.
That meant that those commits would not show (in full) on any email.
The fix is to not use "--all", and instead use "--branches" in the
git-rev-parse command.
Other changes
* Lose the monstrous one-giant-script layout and put things in easy to
digest functions. This makes it much easier to find the place you
need to change if you wanted to customise the output. I've also
tried to write more verbose comments for the same reason. The hook
script is big, mainly because of all the different cases that it has
to handle, so being easy to navigate is important.
* All uses of "git-command" changed to "git command", to cope better
if a user decided not to install all the hard links to git;
* Cleaned up some of the English in the email
* The fact that the receive hook makes the ref available also allows me
to use Shawn Pearce's fantastic suggestion that an annotated tag can
be parsed with git-for-each-ref. This removes the potentially
non-portable use of "<<<" heredocs and the nasty messing around with
"date" to convert numbers of seconds UTC to a real date
* Deletions are now caught and notified (briefly)
* To help with debugging, I've retained the command line mode from the
update hook; but made it so that the output is not emailed, it's just
printed to the screen. This could then be redirected if the user
wanted
* Removed the "Hello" from the beginning of the email - it's just
noise, and no one seriously has their day made happier by "friendly"
programs
* The fact that it doesn't rely on repository state as an indicator any
more means that it's far more stable in its output; hopefully the
same arguments will always generate the same email - even if the
repository changes in the future. This means you can easily recreate
an email should you want to.
* Included Jim Meyering's envelope sender option for the sendmail call
* The hook is now so big that it was inappropriate to copy it
to every repository by keeping it in the templates directory.
Instead, I've put a comment saying to look in contrib/hooks, and
given an example of calling the script from that template hook. The
advantage of calling the script residing at some fixed location is
that if a future package of git included a bug fixed version of the
script, that would be picked up automatically, and the user would not
have to notice and manually copy the new hook to every repository
that uses it.

gitweb: Support comparing blobs (files) with different names
Fix the bug that caused "blobdiff" view called with new style URI
for a rename with change diff to be show as new (added) file diff.
New style URI for "blobdiff" for rename means with $hash_base ('hb') and
$hash_parent_base ('hpb') paramaters denoting tree-ish (usually commit)
of a blobs being compared, together with both $file_name ('f') and
$file_parent ('fp') parameters.
It is done by adding $file_parent ('fp') to the path limiter, meaning
that diff command becomes:
git diff-tree [options] hpb hb -- fp f
Other option would be finding hash of a blob using git_get_hash_by_path
subroutine and comparing blobs using git-diff, or using extended SHA-1
syntax and compare blobs using git-diff:
git diff [options] hpb:fp hp:f

At least in Linux glibc, "getaddrinfo()" has a very irritating feature (or
bug, who knows..).
Namely if you pass it in an empty string for the service name, it will
happily and quietly consider it identical to a NULL port pointer, and
return port number zero and no errors. Which obviously will not work.
Maybe that's what it's really expected to do, although the man-page for
getaddrinfo() certainly implies that it's a bug.
So when somebody passes me a "please pull" request pointing to something
like the following
(note the extraneous colon at the end of the host name), git would happily
try to connect to port 0, which would generally just cause the remote to
not even answer, and the "connect()" will take a long time to time out.
So to work around the glibc feature/bug, just notice this empty port case
automatically. Also, add the port information to the error information
when it fails to look up (maybe it's the host-name that fails, maybe it's
the port-name - we should print out both).

In a path-limited bisection, when the $bad commit is not
changing the limited path, and the number of suspects is 1, the
code miscounted and returned $bad from find_bisection(), which
is not marked with TREECHANGE. This is of course filtered by
the output routine, resulting in an empty output, in turn
causing git-bisect driver to say "$bad was both good and bad".
Illustration. Suppose you have these four commits, and only C
changes path P. You know D is bad and A is good.
A---B---C*--D
git-bisect driver runs this to find a bisection point:
$ git rev-list --bisect A..D -- P
which calls find_bisection() with B, C and D. The set of
commits that is given to this function is the same set of
commits as rev-list without --bisect option and pathspec
returns. Among them, only C is marked with TREECHANGE. Let's
call the set of commits given to find_bisection() that are
marked with TREECHANGE (or all of them if no path limiter is in
effect) "the bisect set". In the above example, the size of the
bisect set is 1 (contains only "C").
For each commit in its input, find_bisection() computes the
number of commits it can reach in the bisect set. For a commit
in the bisect set, this number includes itself, so the number is
1 or more. This number is called "depth", and computed by
count_distance() function.
When you have a bisect set of N commits, and a commit has depth
D, how good is your bisection if you returned that commit? How
good this bisection is can be measured by how many commits are
effectively tested "together" by testing one commit.
Currently you have (N-1) untested commits (the tip of the bisect
set, although it is included in the bisect set, is already known
to be bad). If the commit with depth D turns out to be bad,
then your next bisect set will have D commits and you will have
(D-1) untested commits left, which means you tested (N-1)-(D-1)
= (N-D) commits with this bisection. If it turns out to be good, then
your next bisect set will have (N-D) commits, and you will have
(N-D-1) untested commits left, which means you tested
(N-1)-(N-D-1) = D commits with this bisection.
Therefore, the goodness of this bisection is is min(N-D, D), and
find_bisection() function tries to find a commit that maximizes
this, by initializing "closest" variable to 0 and whenever a
commit with the goodness that is larger than the current
"closest" is found, that commit and its goodness are remembered
by updating "closest" variable. The "the commit with the best
goodness so far" is kept in "best" variable, and is initialized
to a commit that happens to be at the beginning of the list of
commits given to this function (which may or may not be in the
bisect set when path-limit is in use).
However, when N is 1, then the sole tree-changing commit has
depth of 1, and min(N-D, D) evaluates to 0. This is not larger
than the initial value of "closest", and the "so far the best
one" commit is never replaced in the loop.
When path-limit is not in use, this is not a problem, as any
commit in the input set is tree-changing. But when path-limit
is in use, and when the starting "bad" commit does not change
the specified path, it is not correct to return it.
Fix copy'n'paste error in commit c9d193df which caused that "next"
link for merge commits in "commit" view

The branch you are on while bisecting is always "bisect", and
checking for "refs/heads/bisect*" is wrong. Only check if it is
exactly "refs/heads/bisect".
checkout: report where the new HEAD is upon detaching HEAD
After "git reset" moves the HEAD around, it reports which commit
you are on, which gives the user a warm fuzzy feeling of
assurance. Give the same assurance from git-checkout when
moving the detached HEAD around.
Bisect: convert revs given to good and bad to commits
Without this the rev could be (e.g.) a tag and then the condition to end the
bisect might fail and you have to check the already known to be bad revision
once more.
