Many error status codes simply default to 403 Forbidden, which is not
correct in most cases. This patch makes gitweb return semantically
correct status codes.
For convenience the die_error function now only takes the status code
without reason as first parameter (e.g. 404 instead of "404 Not
Found"), and it now defaults to 500 (Internal Server Error), even
though the default is not used anywhere.

Make git_dir a path relative to work_tree in setup_work_tree()
Once we find the absolute paths for git_dir and work_tree, we can make
git_dir a relative path since we know pwd will be work_tree. This should
save the kernel some time traversing the path to work_tree all the time
if git_dir is inside work_tree.
Daniel's patch didn't apply for me as-is, so I recreated it with some
differences, and here are the numbers from ten runs each.
There is some IO for me - probably due to more-or-less random flushing of
the journal - so the variation is bigger than I'd like, but whatever:
Before:
real 0m8.135s
real 0m7.933s
real 0m8.080s
real 0m7.954s
real 0m7.949s
real 0m8.112s
real 0m7.934s
real 0m8.059s
real 0m7.979s
real 0m8.038s
After:
real 0m7.685s
real 0m7.968s
real 0m7.703s
real 0m7.850s
real 0m7.995s
real 0m7.817s
real 0m7.963s
real 0m7.955s
real 0m7.848s
real 0m7.969s
Now, going by "best of ten" (on the assumption that the longer numbers
are all due to IO), I'm saying a 7.933s -> 7.685s reduction, and it does
seem to be outside of the noise (ie the "after" case never broke 8s, while
the "before" case did so half the time).
So looks like about 3% to me.
Doing it for a slightly smaller test-case (just the "arch" subdirectory)
gets more stable numbers probably due to not filling the journal with
metadata updates, so we have:
Before:
real 0m1.633s
real 0m1.633s
real 0m1.633s
real 0m1.632s
real 0m1.632s
real 0m1.630s
real 0m1.634s
real 0m1.631s
real 0m1.632s
real 0m1.632s
After:
real 0m1.610s
real 0m1.609s
real 0m1.610s
real 0m1.608s
real 0m1.607s
real 0m1.610s
real 0m1.609s
real 0m1.611s
real 0m1.608s
real 0m1.611s
where I'ld just take the averages and say 1.632 vs 1.610, which is just
over 1% peformance improvement.
So it's not in the noise, but it's not as big as I initially thought and
measured.
(That said, it obviously depends on how deep the working directory path is
too, and whether it is behind NFS or something else that might need to
cause more work to look up).
Due to a misplaced list block separator, general hints about the config
file options got indented at the same level as the description of the last
option, making it easy to miss them.

t7502-commit.sh: test_must_fail doesn't work with inline environment variables
When the arguments to test_must_fail() begin with a variable assignment,
test_must_fail() attempts to execute the variable assignment as a command.
This fails, and so test_must_fail returns with a successful status value
without running the command it was intended to test.
For example, the following script:
#!/bin/sh
test_must_fail () {
"$@"
test $? -gt 0 -a $? -le 129
}
foo='wo adrian'
test_must_fail foo='yo adrian' sh -c 'echo foo: $foo'
always exits zero and prints the message:
test.sh: line 3: foo=yo adrian: command not found
Test 16 calls test_must_fail in such a way and therefore has not been
testing whether git 'do[es] not fire editor in the presence of conflicts'.
A workaround is to set and export the variable in a normal way, not
using one-shot notation. Because this would affect the remainder of
the process, the test is done inside a subshell.

In repos with many refs, it is unlikely that most refs will ever change.
This fact is already exploited by "git gc" by executing "git pack-refs"
to consolidate all refs into a single file.
When cloning a repo with many refs, it does not make sense to create the
loose refs in the first place, just to have the next "git gc" consolidate
them into one file. Instead, make "git clone" create the packed refs file
immediately, and forego the loose refs completely.

clean up error conventions of remote.c:match_explicit
match_explicit is called for each push refspec to try to
fully resolve the source and destination sides of the
refspec. Currently, we look at each refspec and report
errors on both the source and the dest side before aborting.
It makes sense to report errors for each refspec, since an
error in one is independent of an error in the other.
However, reporting errors on the 'dst' side of a refspec if
there has been an error on the 'src' side does not
necessarily make sense, since the interpretation of the
'dst' side depends on the 'src' side (for example, when
creating a new unqualified remote ref, we use the same type
as the src ref).
This patch lets match_explicit return early when the src
side of the refspec is bogus. We still look at all of the
refspecs before aborting the push, though.
At the same time, we clean up the call signature, which
previously took an extra "errs" flag. This was pointless, as
we didn't act on that flag, but rather just passed it back
to the caller. Instead, we now use the more traditional
"return -1" to signal an error, and the caller aggregates
the error count.
This change fixes two bugs, as well:
- the early return avoids a segfault when passing a NULL
matched_src to guess_ref()
- the check for multiple sources pointing to a single dest
aborted if the "err" flag was set. Presumably the intent
was not to bother with the check if we had no
matched_src. However, since the err flag was passed in
from the caller, we might abort the check just because a
previous refspec had a problem, which doesn't make
sense.
In practice, this didn't matter, since due to the error
flag we end up aborting the push anyway.

It worked that way since commit 50f575fc (Tweak diff colors,

changed it. This patch restores the old behaviour.
Besides Linus' arguments in the log message of 50f575fc, resetting color
before printing newline is also important to keep 'git add --patch'
happy. If the last line(s) of a file are removed, then that hunk will
end with a colored line. However, if the newline comes before the color
reset, then the diff output will have an additional line at the end
containing only the reset sequence. This causes trouble in
git-add--interactive.perl's parse_diff function, because @colored will
have one more element than @diff, and that last element will contain the
color reset. The elements of these arrays will then be copied to @hunk,
but only as many as the number of elements in @diff. As a result the
last color reset is lost and all subsequent terminal output will be
printed in color.

Now that we've made the loose SHA1 file reading more careful and

As such, the whole 'return stat information' part of it was just
pointless (nobody cares any more), and the naming of the function is not
really all that relevant either.
So simplify it to not do a 'stat()', but just an existence check (which

- it unnecessarily walks the filename twice (at 'stat()' time and then
again to open it)
- NFS generally has open-close consistency guarantees, which means that
the initial 'stat()' was technically done outside of the normal
consistency rules.
So change it to do 'open()+fstat()+mmap()+close()' instead, which avoids
both these issues.

Avoid cross-directory renames and linking on object creation
Instead of creating new temporary objects in the top-level git object
directory, create them in the same directory they will finally end up in
anyway. This avoids making the final atomic "rename to stable name"
operation be a cross-directory event, which makes it a lot easier for
various filesystems.
Several filesystems do things like change the inode number when moving
files across directories (or refuse to do it entirely).
In particular, it can also cause problems for NFS implementations that
change the filehandle of a file when it moves to a different directory,
like the old user-space NFS server did, and like the Linux knfsd still
does if you don't export your filesystems with 'no_subtree_check' or if
you export a filesystem that doesn't have stable inode numbers across
renames).
This change also obviously implies creating the object fan-out
subdirectory at tempfile creation time, rather than at the final
move_temp_to_file() time. Which actually accounts for most of the size
of the patch.

git-svn: don't append extra newlines at the end of commit messages.
In git, all commits end in exactly one newline character. In svn, commits
end in zero or more newlines. Thus, when importing commits from svn into
git, git-svn always appends two extra newlines to ensure that the
git-svn-id: line is separated from the main commit message by at least one
blank line.
Combined with the terminating newline that's always present in svn commits
produced by git, you usually end up with two blank lines instead of one
between the commit message and git-svn-id: line, which is undesirable.
Instead, let's remove all trailing whitespace from the git commit on the way

If we are exporting a commit which has no parents we may be doing

to produce an incorrect graph for:
A-------M----o------o refs/heads/master
/
B-+
In this graph A and B are initial commits (no parents) but if A was
output first to refs/heads/master and then B is output fast-import
would assume the graph was this instead:
A-------M----o------o refs/heads/master
\ /
+-B-+
Which would cause B, M, and all later commits to have a different
SHA-1, and obviously be quite a different graph.
Sending a reset command prior to B informs fast-import to clear
the implied parent of A, allowing B to remain an initial commit.
