To prevent funky games with external diff engines, git-log and
friends prevent external diff engines from being called. That makes
sense in the context of git-format-patch or git-rebase.
However, for "git log -p" it is not so nice to get the message
that binary files cannot be compared, while "git diff" has no
problems with them, if you provided an external diff driver.
With this patch, "git log --ext-diff -p" will do what you expect,
and the option "--no-ext-diff" can be used to override that
setting.

Don't smash stack when $GIT_ALTERNATE_OBJECT_DIRECTORIES is too long
There is no restriction on the length of the name returned by
get_object_directory, other than the fact that it must be a stat'able
git object directory. That means its name may have length up to
PATH_MAX-1 (i.e., often 4095) not counting the trailing NUL.
Combine that with the assumption that the concatenation of that name and
suffixes like "/info/alternates" and "/pack/---long-name---.idx" will fit
in a buffer of length PATH_MAX, and you see the problem. Here's a fix:
sha1_file.c (prepare_packed_git_one): Lengthen "path" buffer
so we are guaranteed to be able to append "/pack/" without checking.
Skip any directory entry that is too long to be appended.
(read_info_alternates): Protect against a similar buffer overrun.
Before this change, using the following admittedly contrived environment
setting would cause many git commands to clobber their stack and segfault
on a system with PATH_MAX == 4096:
t=$(perl -e '$s=".git/objects";$n=(4096-6-length($s))/2;print "./"x$n . $s')
export GIT_ALTERNATE_OBJECT_DIRECTORIES=$t
touch g
./git-update-index --add g
If you run the above commands, you'll soon notice that many
git commands now segfault, so you'll want to do this:
unset GIT_ALTERNATE_OBJECT_DIRECTORIES

Start deprecating "git-command" in favor of "git command"
I realize that a lot of people use the "git-xyzzy" format, and we have
various historical reasons for it, but I also think that most people have
long since started thinking of the git command as a single command with
various subcommands, and we've long had the documentation talk about it
that way.
Slowly migrating away from the git-xyzzy format would allow us to
eventually no longer install hundreds of binaries (even if most of them
are symlinks or hardlinks) in users $PATH, and the _original_ reasons for
it (implementation issues and bash completion) are really long long gone.
Using "git xyzzy" also has some fundamental advantages, like the ability
to specify things like paging ("git -p xyzzy") and making the whole notion
of aliases act like other git commands (which they already do, but they do
*not* have a "git-xyzzy" form!)
Anyway, while actually removing the "git-xyzzy" things is not practical
right now, we can certainly start slowly to deprecate it internally inside
git itself - in the shell scripts we use, and the test vectors.
This patch adds a "remove-dashes" makefile target, which does that. It
isn't particularly efficient or smart, but it *does* successfully rewrite
a lot of our shell scripts to use the "git xyzzy" form for all built-in
commands.
(For non-builtins, the "git xyzzy" format implies an extra execve(), so
this script leaves those alone).
So apply this patch, and then run
make remove-dashes
make test
git commit -a
to generate a much larger patch that actually starts this transformation.
(The only half-way subtle thing about this is that it also fixes up
git-filter-branch.sh for the new world order by adding quoting around
the use of "git-commit-tree" as an argument. It doesn't need it in that
format, but when changed into "git commit-tree" it is no longer a single
word, and the quoting maintains the old behaviour).
NOTE! This does not yet mean that you can actually stop installing the
"git-xyzzy" binaries for the builtins. There are some remaining places
that want to use the old form, this just removes the most obvious ones
that can easily be done automatically.

"git-push $URL" without refspecs pushes only matching branches
When "git push" is run without any refspec (neither on the
command line nor in the config), we used to push "matching refs"
in the sense that anything under refs/ hierarchy that exist on
both ends were updated. This used to be a sane default for
publishing your repository to another back when we did not have
refs/remotes/ hierarchy, but it does not make much sense these
days.
This changes the semantics to push only "matching branches".
This repository was a strange one in that it was being used to provide
its own submodule. That is, the repository was cloned into a
subdirectory, an independent branch checked out in that subdirectory,
and then it was marked as a submodule. git-prune then failed in the
above manner.
The problem was that git-prune was not submodule aware in two areas.
Linus said:
> So what happens is that something traverses a tree object, looks at each
> entry, sees that it's not a tree, and tries to look it up as a blob. But
> subprojects are commits, not blobs, and then when you look at the object
> more closely, you get the above kind of object type confusion.
and included a patch to add an S_ISGITLINK() test to reachable.c's
process_tree() function. That fixed the first git-prune error, and
stopped it from trying to process the gitlink entries in trees as if
they were pointers to other trees (and of course failing, because
gitlinks _aren't_ trees). That part of this patch is his.
The second area is add_cache_refs(). This is called before starting the
reachability analysis, and was calling lookup_blob() on every object
hash found in the index. However, it is no longer true that every hash
in the index is a pointer to a blob, some of them are gitlinks, and are
not backed by any object at all, they are commits in another repository.
Normally this bug was not causing any problems, but in the case of the
self-referencing repository described above, it meant that the gitlink
hash was being marked as being of type OBJ_BLOB by add_cache_refs() call
to lookup_blob(). Then later, because that hash was also pointed to by
a ref, add_one_ref() would treat it as a commit; lookup_commit() would
return a NULL because that object was already noted as being an
OBJ_BLOB, not an OBJ_COMMIT; and parse_commit_buffer() would SEGFAULT on
that NULL pointer.
The fix made by this patch is to not blindly call lookup_blob() in
reachable.c's add_cache_refs(), and instead skip any index entries that
are S_ISGITLINK().

diffcore-delta.c: Ignore CR in CRLF for text files
This ignores CR byte in CRLF sequence in text file when
computing similarity of two blobs.
Usually this should not matter as nobody sane would be checking
in a file with CRLF line endings to the repository (they would
use autocrlf so that the repository copy would have LF line
endings).
diffcore-delta.c: update the comment on the algorithm.
The comment at the top of the file described an old algorithm
that was neutral to text/binary differences (it hashed sliding
window of N-byte sequences and counted overlaps), but long time
ago we switched to a new heuristics that are more suitable for
line oriented (read: text) files that are much faster.
diffcore-break and diffcore-rename would want to behave slightly
differently depending on the binary-ness of the data, so add one
bit to the filespec, as the structure is now passed down to
diffcore_count_changes() function.
We may want to use richer information on the data we are dealing
with in this function, so instead of passing a buffer address
and length, just pass the diffcore_filespec structure. Existing
callers always call this function with parameters taken from a
filespec anyway, so there is no functionality changes.

This patch arose from a discussion started by Jim Meyering's patch
whose intention was to provide better diagnostics for failed writes.
Linus proposed a better way to do things, which also had the added
benefit that adding a fflush() to git-log-* operations and incremental
git-blame operations could improve interactive respose time feel, at
the cost of making things a bit slower when we aren't piping the
output to a downstream program.
This patch skips the fflush() calls when stdout is a regular file, or
if the environment variable GIT_FLUSH is set to "0". This latter can
speed up a command such as:
GIT_FLUSH=0 strace -c -f -e write time git-rev-list HEAD | wc -l

This switches the checks around upon the exit codepath of the
git wrapper, so that we may recover at least non-transient errors.
It's still not perfect. As I've been harping on, stdio simply isn't very
good for error reporting. For example, if an IO error happened, you'd want
to see EIO, wouldn't you? And yes, that's what the kernel would return.
However, with buffered stdio (and flushing outside of our control), what
would likely happen is that some intermediate error return _does_ return
EIO, but then the kernel might decide to re-mount the filesystem read-only
due to the error, and the actual *report* for us might be
"write failure on standard output: read-only filesystem"
which lost the EIO.
