checkout -f: deal with a D/F conflict entry correctly
When we switch branches with "checkout -f", unpack_trees() feeds two
cache_entries to oneway_merge() function in its src[] array argument. The
zeroth entry comes from the current index, and the first entry represents
what the merge result should be, taken from the tree recorded in the
commit we are switching to.
When we have a blob (either regular file or a symlink) in the index and in
the work tree at path "foo", and the switched-to tree has "foo/bar",
i.e. "foo" becomes a directory, src[0] is obviously that blob currently
registered at "foo". Even though we do not have anything at "foo" in the
switched-to tree, src[1] is _not_ NULL in this case.
The unpack_trees() machinery places a special marker df_conflict_entry
to signal that no blob exists at "foo", but it will become a directory
that may have somthing underneath it (namely "foo/bar"), so a usual 3-way
merge can notice the situation.
But oneway_merge() codepath failed to notice this and passed the special
marker directly to merged_entry(). This happens to remove the "foo" in
the end because the df_conflict_entry does not have any name (hence the
"error" message) and its addition in add_index_entry() is rejected, but it
is wrong.

sha1_name.c: avoid unnecessary strbuf_release
When we fall back to a standard for_each_reflog_ent() after failing to find
the nth branch switch (or if we had a short reflog) with the call to
for_each_recent_reflog_ent(), we do not need to free the memory allocated
for our strbuf's since a strbuf_reset() will be performed in
grab_nth_branch_switch() before assigning to the entry.
Plus, the strbuf_release() negates the non-zero hint we initially gave to
strbuf_init() just above these lines.

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

avoid exponential regex match for java and objc function names
In the old regex
^[ \t]*(([ \t]*[A-Za-z_][A-Za-z_0-9]*){2,}[ \t]*\([^;]*)$
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
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.

Fix big left-shifts of unsigned char
Shifting 'unsigned char' or 'unsigned short' left can result in sign
extension errors, since the C integer promotion rules means that the
unsigned char/short will get implicitly promoted to a signed 'int' due to
the shift (or due to other operations).
This normally doesn't matter, but if you shift things up sufficiently, it
will now set the sign bit in 'int', and a subsequent cast to a bigger type
(eg 'long' or 'unsigned long') will now sign-extend the value despite the
original expression being unsigned.
One example of this would be something like
unsigned long size;
unsigned char c;
size += c << 24;
where despite all the variables being unsigned, 'c << 24' ends up being a
signed entity, and will get sign-extended when then doing the addition in
an 'unsigned long' type.
Since git uses 'unsigned char' pointers extensively, we actually have this
bug in a couple of places.
I may have missed some, but this is the result of looking at
git grep '[^0-9 ][ ]*<<[ ][a-z]' -- '*.c' '*.h'
git grep '<<[ ]*24'
which catches at least the common byte cases (shifting variables by a
variable amount, and shifting by 24 bits).
I also grepped for just 'unsigned char' variables in general, and
converted the ones that most obviously ended up getting implicitly cast
immediately anyway (eg hash_name(), encode_85()).
In addition to just avoiding 'unsigned char', this patch also tries to use
a common idiom for the delta header size thing. We had three different
variations on it: "& 0x7fUL" in one place (getting the sign extension
right), and "& ~0x80" and "& 0x7f" in two other places (not getting it
right). Apart from making them all just avoid using "unsigned char" at
all, I also unified them to then use a simple "& 0x7f".
I considered making a sparse extension which warns about doing implicit

Shifting 'unsigned char' or 'unsigned short' left can result in sign
extension errors, since the C integer promotion rules means that the
unsigned char/short will get implicitly promoted to a signed 'int' due to
the shift (or due to other operations).
This normally doesn't matter, but if you shift things up sufficiently, it
will now set the sign bit in 'int', and a subsequent cast to a bigger type
(eg 'long' or 'unsigned long') will now sign-extend the value despite the
original expression being unsigned.
One example of this would be something like
unsigned long size;
unsigned char c;
size += c << 24;
where despite all the variables being unsigned, 'c << 24' ends up being a
signed entity, and will get sign-extended when then doing the addition in
an 'unsigned long' type.
Since git uses 'unsigned char' pointers extensively, we actually have this
bug in a couple of places.
I may have missed some, but this is the result of looking at
git grep '[^0-9 ][ ]*<<[ ][a-z]' -- '*.c' '*.h'
git grep '<<[ ]*24'
which catches at least the common byte cases (shifting variables by a
variable amount, and shifting by 24 bits).
I also grepped for just 'unsigned char' variables in general, and
converted the ones that most obviously ended up getting implicitly cast
immediately anyway (eg hash_name(), encode_85()).
In addition to just avoiding 'unsigned char', this patch also tries to use
a common idiom for the delta header size thing. We had three different
variations on it: "& 0x7fUL" in one place (getting the sign extension
right), and "& ~0x80" and "& 0x7f" in two other places (not getting it
right). Apart from making them all just avoid using "unsigned char" at
all, I also unified them to then use a simple "& 0x7f".
I considered making a sparse extension which warns about doing implicit
casts from unsigned types to signed types, but it gets rather complex very
quickly, so this is just a hack.

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>
C: 003bgit-upload-pack /pub/linux-2.6.git\0host=git.kernel.org\0
S: ...git-upload-pack header...
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.

"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

fix cat-file usage message and documentation
cat-file with an object on the command line requires an
option to tell it what to output (type, size, pretty-print,
etc). However, the square brackets in the usage imply that
those options are not required. This patch switches them to
parentheses to indicate "required but grouped-OR" (curly
braces might also work, but this follows the convention used
already by "git stash").
While we're at it, let's change the <sha1> specifier in the
usage to <object>. That's what the documentation uses, and
it does actually use the regular object lookup.

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
conflicts. However, ref storage might fail for other
reasons (e.g., permissions problems) in which case the
advice is useless and misleading.
This patch detects when there is an actual DF situation and
only issues the advice when one is found.

lock_ref: inform callers of unavailable ref
One of the ways that locking might fail is that there is a
DF conflict between two refs (e.g., you want to lock
"foo/bar" but "foo" already exists). In this case, we return
an error, but there is no way for the caller to know the
specific problem.
This patch sets errno to ENOTDIR, which is the most sensible
code. It's what we would see if the refs were stored purely
in the filesystem (but these days we must check the
namespace manually due to packed refs).

Change xdl_merge to generate output even for null merges
xdl_merge used to have a check to ensure that there was at least
some change in one or other side being merged but this suppressed
output for the degenerate case when base, local and remote

Removing this check enables correct output in the degenerate case
and xdl_free_script handles freeing NULL scripts so there is no

commit: -F overrides -t
Commit dbd0f5c7 (Files given on the command line are relative to $cwd,
2008-08-06) introduced parse_options_fix_filename() as a quick fix for
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().

grep: fix word-regexp colouring
As noticed by Dmitry Gryazin: When a pattern is found but it doesn't
start and end at word boundaries, bol is forwarded to after the match and
the pattern is searched again. When a pattern is finally found between
word boundaries, the match offsets are off by the number of characters
that have been skipped.
This patch corrects the offsets to be relative to the value of bol as
passed to match_one_pattern() by its caller.

for-each-ref: fix segfault in copy_email
You can trigger a segfault in git.git by doing:
git for-each-ref --format='%(taggeremail)' refs/tags/v0.99
The v0.99 tag is special in that it contains no "tagger"
header.
The bug is obvious in copy_email, which carefully checks to
make sure the result of a strchr is non-NULL, but only after
already having used it to perform other work. The fix is to
move the check up.
