attribute: whitespace set to true detects all errors known to git
That is what the documentation says, but the code pretends as if all the
known whitespace error tokens were given.
Among the whitespace error tokens, there is one kind that loosens the rule
when set: cr-at-eol. Which means that whitespace error token that is set
to true ignores a newly introduced CR at the end, which is inconsistent
with the documentation.
I think this is because the "whitespace" attribute is set to *.[ch] files
without specifying what kind of errors are caught. It makes git "notice
all types of errors" (as described in the documentation), but I think it
is incorrectly setting cr-at-eol, too, and hides this error.

On Cygwin, poll() reports POLLIN even for file descriptors that have

In addition to POLLIN, check if read() returned 0, which indicates
end-of-file, and keep looping only as long as at least one of the file
descriptors has input. This lets the following command finish on its

you can backtrack arbitrarily from [A-Za-z_0-9]* into [A-Za-z_], thus
causing an exponential number of backtracks. Ironically it also causes
the regex not to work as intended; for example "catch" can match the
underlined part of the regex, the first repetition matching "c" and
the second matching "atch".
The replacement regex avoids this problem, because it makes sure that
at least a space/tab is eaten on each repetition. In other words,
a suffix of a repetition can never be a prefix of the next repetition.

fetch-pack: close output channel after sideband demultiplexer terminates
fetch-pack runs the sideband demultiplexer using start_async(). This
facility requires that the asynchronously executed function closes the
output file descriptor (see Documentation/technical/api-run-command.txt).
But the sideband demultiplexer did not do that. This fixes it.
In certain error situations this could lock up a fetch operation on
Windows because the asynchronous function is run in a thread; by not
closing the output fd the reading end never got EOF and waited for more
data indefinitely. On Unix this is not a problem because the asynchronous
function is run in a separate process, which exits after the function ends
and so implicitly closes the output.
Since the pack that is sent over the wire encodes the number of objects in
the stream, during normal operation the reading end knows when the stream
ends and terminates by itself, and does not lock up.

daemon: Strictly parse the "extra arg" part of the command
Since 1.4.4.5 (49ba83fb67 "Add virtualization support to git-daemon")
git daemon enters an infinite loop and never terminates if a client
hides any extra arguments in the initial request line which is not
exactly "\0host=blah\0".
Since that change, a client must never insert additional extra
arguments, or attempt to use any argument other than "host=", as
any daemon will get stuck parsing the request line and will never
complete the request.
Since the client can't tell if the daemon is patched or not, it
is not possible to know if additional extra args might actually be
able to be safely requested.
If we ever need to extend the git daemon protocol to support a new
feature, we may have to do something like this to the exchange:
# If both support git:// v2
#
C: 000cgit://v2
S: 0010ok host user
C: 0018host git.kernel.org
C: 0027git-upload-pack /pub/linux-2.6.git
S: ...git-upload-pack header...
# If client supports git:// v2, server does not:
#
C: 000cgit://v2
S: <EOF>
This requires the client to create two TCP connections to talk to
an older git daemon, however all daemons since the introduction of
daemon.c will safely reject the unknown "git://v2" command request,
so the client can quite easily determine the server supports an
older protocol.

The command "git grep -w ''" dies as soon as it encounters an empty line,

"diff-tree" with pathspec set to the path we are interested in with the

"changed from the parent", "created when there was none") or nothing (when
there is no change from the parent).
If the path used to be a directory, however, we will also see unbounded
number of entries that talk about the files that used to exist underneath
the directory in question. Correctly pick only the entry that describes
the path we are interested in in such a case (namely, the creation of the
path as a regular file).

fetch: report ref storage DF errors more accurately
When we fail to store a fetched ref, we recommend that the
user try running "git prune" to remove up any old refs that
have been deleted by the remote, which would clear up any DF

specific problem.

code. It's what we would see if the refs were stored purely
in the filesystem (but these days we must check the

Commit dbd0f5c7 (Files given on the command line are relative to $cwd,

filename arguments used in the parse options API.
git-commit was still broken. This means
git commit -F log -t temp
in a subdirectory would make git think the log message should be taken
from temp instead of log.
This is because parse_options_fix_filename() calls prefix_filename()
which uses a single static char buffer to do its work. Making two calls
with two char pointers causes the pointers to alias. To prevent
aliasing, we duplicate the string returned by
parse_options_fix_filename().

dir.c: clean up handling of 'path' parameter in read_directory_recursive()
Right now we pass two different pathnames ('path' and 'base') down to
read_directory_recursive(), and the only real reason for that is that we
want to allow an empty 'base' parameter, but when we do so, we need the
pathname to "opendir()" to be "." rather than the empty string.
And rather than handle that confusion in the caller, we can just fix
read_directory_recursive() to handle the case of an empty path itself,
by just passing opendir() a "." ourselves if the path is empty.
This would allow us to then drop one of the pathnames entirely from the
calling convention, but rather than do that, we'll start separating them
out as a "filesystem pathname" (the one we use for filesystem accesses)
and a "git internal base name" (which is the name that we use for git
internally).
That will eventually allow us to do things like handle different
encodings (eg the filesystem pathnames might be Latin1, while git itself
would use UTF-8 for filename information).

This patch fixes the issue by enclosing non branch names in a pair of

It also fixes a small bug where the branch part is left empty when
.git/HEAD is unreadable for whatever reason. The output now says
"(unknown)".
completion: fix PS1 display during a merge on detached HEAD
If your merge stops in a conflict while on a detached HEAD, recent
completion code fails to show anything. This was because various cases
added to support the operation-in-progress markers (e.g. REBASE, MERGING)
forgot that they need to set the variable "b" to something for the result
they computed to be displayed at all.

The logic in 83ae209 (checkout branch: prime cache-tree fully,
2009-04-20) is bogus; checkout can switch branches with a dirty
index and in such a case the tree won't match HEAD.
merge-recursive: never leave index unmerged while recursing
When you are trying to come up with the final result (i.e. depth=0), you
want to record how the conflict arose by registering the state of the
common ancestor, your branch and the other branch in the index, hence you
want to do update_stages().
When you are merging with positive depth, that is because of a criss-cross
merge situation. In such a case, you would need to record the tentative
result, with conflict markers and all, as if the merge went cleanly, even
if there are conflicts, in order to write it out as a tree object later to
be used as a common ancestor tree.
update_file() calls update_file_flags() with update_cache=1 to signal that
the result needs to be written to the index at stage #0 (i.e. merged), and
the code should not clobber the index further by calling update_stages().
The codepath to deal with rename/delete conflict in a recursive merge
however left the index unmerged.

Teach 'git checkout' to preload the index contents
This makes git checkout know to use the threaded index preloading if it
is enabled in the config file. You need to have
[core]
preloadindex = true
in your config file to see it, and for that feature to make sense your
filesystem needs to be able to do concurrent 'lstat()' lookups, but when
that is the case (especially NFS over a high-latency network), this can
be a noticeable performance win.
But with a low-latency network and at least older Linux NFS clients, this
will clearly potentially cause a lot of lock contention. It may still
speed up the uncached case, but the threading and locking overhead will
result in the cached case likely slowing down.
That was almost certainly fixed by Linux commit fc0f684c2 ("NFS: Remove
BKL from NFS lookup code"), but that one got merged into 2.6.27-rc1, so
older kernel versions than 2.6.27 will not scale very well.
But regardless, it's the right thing to do. If your filesystem doesn't
scale, don't enable index preloading.

Avoid unnecessary 'lstat()' calls in 'get_stat_data()'
When we ask get_stat_data() to get the mode and size of an index entry,
we can avoid the lstat() call if we have marked the index entry as being
uptodate due to earlier lstat() calls.
This avoids a lot of unnecessary lstat() calls in eg 'git checkout',
where the last phase shows the differences to the working tree
(requiring a diff), but earlier phases have already verified the index.
On the kernel repo (with a fast machine and everything cached), this
changes timings of a nul 'git checkout' from
so it can obviously be noticeable, although equally obviously it's not a
show-stopper on this particular machine. The difference is likely larger
on slower machines, or with operating systems that don't do as good a job
of name caching.
