Fix archive format with -- on the command line
Giving --format from the command line, or using output file extention to
DWIM the output format, with a pathspec that is disambiguated with an
explicit double-dash on the command line, e.g.
git archive -o file --format=zip HEAD -- path
git archive -o file.zip HEAD -- path
didn't work correctly.
This was because the code reordered (when one was given) or added (when
the format was inferred) a --format argument at the end, effectively
making it to "archive HEAD -- path --format=zip", i.e. an extra pathspec
that is unlikely to match anything.
The command line argument list should always be "options, revs and then
paths", and we should set a good example by inserting the --format at the
beginning instead.

add-interactive: fix deletion of non-empty files
Commit 24ab81a fixed the deletion of empty files, but broke
deletion of non-empty files. The approach it took was to
factor out the "deleted" line from the patch header into its
own hunk, the same way we do for mode changes. However,
unlike mode changes, we only showed the special "delete this
file" hunk if there were no other hunks. Otherwise, the user
would annoyingly be presented with _two_ hunks: one for
deleting the file and one for deleting the content.
This meant that in the non-empty case, we forgot about the
deleted line entirely, and we submitted a bogus patch to
git-apply (with "/dev/null" as the destination file, but not
marked as a deletion).
Instead, this patch combines the file deletion hunk and the
content deletion hunk (if there is one) into a single
deletion hunk which is either staged or not.

Fix diff -B/--dirstat miscounting of newly added contents
What used to happen is that diffcore_count_changes() simply ignored any
hashes in the destination that didn't match hashes in the source. EXCEPT
if the source hash didn't exist at all, in which case it would count _one_
destination hash that happened to have the "next" hash value. As a
consequence, newly added material was often undercounted, making output
from --dirstat and "complete rewrite" detection used by -B unrelialble.
This changes it so that:
- whenever it bypasses a destination hash (because it doesn't match a
source), it counts the bytes associated with that as "literal added"
- at the end (once we have used up all the source hashes), we do the same
thing with the remaining destination hashes.
- when hashes do match, and we use the difference in counts as a value,
we also use up that destination hash entry (the 'd++').

reset: improve worktree safety valves
The existing code checked to make sure we were not in a bare
repository when doing a hard reset. However, we should take
this one step further, and make sure we are in a worktree.
Otherwise, we can end up munging files inside of '.git'.
Furthermore, we should do the same check for --merge resets,
which have the same properties. Actually, a merge reset of
HEAD^ would already complain, since further down in the code
we want a worktree. However, it is nicer to check up-front;
then we are sure we cover all cases ("git reset --merge"
would run, even though it wasn't doing anything) and we can
give a more specific message.
Add tests to t7103 to cover these cases and some missing ones.

Documentation: xmlto 0.0.18 does not know --stringparam
Newer DocBook stylesheets want man.base.url.for.relative.links
parameter set when formatting manpages with external references
to turn them into full URLs, and leave a helpful "you should
set this parameter" message in the output. Earlier we added
the MAN_BASE_URL make variable to specify the value for it.
When MAN_BASE_URL is not given, it ought to be safe to set the
parameter to empty; it would result in an empty leading path for
older stylesheets that ignore the parameter, and newer ones
would produce the same "relative URL" without the message.
Unfortunately, older xmlto (at least version 0.0.18 released in
early 2004 that comes with RHEL/CentOS 5) does not understand
the --stringparam command line option, so we cannot add the
parameter definition unconditionally to the command line. Work
it around by passing the parameter only when set.
If you do not have a suitable URL prefix, you can pass a quoted empty
string to it, like so:
$ make MAN_BASE_URL='""'

git_merge_trees(), which prevented using the same messages easily from

builtin-merge.c: call exclude_cmds() correctly.
We need to call exclude_cmds() after the loop, not during the loop, because
excluding a command from the array can change the indexes of objects in the

weren't excluded as they should have been.

Remove dead code from "git am"
Ever since the initial implementation, "git am" had kept a dead code that
never triggered due to a typo in the variable name. Worse yet, the code,
if it weren't for the typo, would have attempted to add "[PATCH] " at the
beginning of the Subject: header when "git am" is run with its "-k"
option. However, because "git am -k" tells mailinfo to keep such prefix
when parsing the input, the "[PATCH] " added by this dead code would have
really been unnecessary duplicate.
Embarrassing is that we kept _maintaining_ the codepath without anybody
noticing for four years.

builtin-apply.c: pay attention to -p<n> when determining the name
The patch structure has def_name component that is used to validate the
sanity of a "diff --git" patch by checking pathnames that appear on the
patch header lines for consistency. The git_header_name() function is
used to compute this out of "diff --git a/... b/..." line, but the code
always stripped one level of prefix (i.e. "a/" and "b/"), without paying
attention to -p<n> option. Code in find_name() function that parses other
lines in the patch header (e.g. "--- a/..." and "+++ b/..." lines) however
did strip the correct number of leading paths prefixes, and the sanity
check between these computed values failed.

pack-objects: split implications of --all-progress from progress activation
Currently the --all-progress flag is used to use force progress display
during the writing object phase even if output goes to stdout which is
primarily the case during a push operation. This has the unfortunate
side effect of forcing progress display even if stderr is not a
terminal.
Let's introduce the --all-progress-implied argument which has the same
intent except for actually forcing the activation of any progress
display. With this, progress display will be automatically inhibited
whenever stderr is not a terminal, or full progress display will be
included otherwise. This should let people use 'git push' within a cron
job without filling their logs with useless percentage displays.

instaweb: restart server if already running
Running 'git instaweb' when an instaweb server is already running will
fail (at least when the port is the same) and overwrite the pid file
used to track the currently running server. This turns out to be
especially annoying when the user tries to stop the previously running
server with 'git instaweb --stop' and is instead greeted with an error
message because the pid file has been destroyed.
Instead of allowing a user to start two instaweb servers, stop the
currently running server first and then start the new one. This should
be fine because it was never really possible to start two instaweb

Protect scripted Porcelains from GREP_OPTIONS insanity
If the user has exported the GREP_OPTIONS environment variable, the output
from "grep" and "egrep" in scripted Porcelains may be different from what
they expect. For example, we may want to count number of matching lines,
by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use.
The approach taken by this change to address this issue is to protect only
our own use of grep/egrep. Because we do not unset it at the beginning of
our scripts, hook scripts run from the scripted Porcelains are exposed to
the same insanity this environment variable causes when grep/egrep is used
to implement logic (e.g. "grep | wc -l"), and it is entirely up to the
hook scripts to protect themselves.
On the other hand, applypatch-msg hook may want to show offending words in
the proposed commit log message using grep to the end user, and the user
might want to set GREP_OPTIONS=--color to paint the match more visibly.
The approach to protect only our own use without unsetting the environment
variable globally will allow this use case.

diffcore-break: save cnt_data for other phases
The "break" phase works by counting changes between two
blobs with the same path. We do this by splitting the file
into chunks (or lines for text oriented files) and then
keeping a count of chunk hashes.
The "rename" phase counts changes between blobs at two
different paths. However, it uses the exact same set of
chunk hashes (which are immutable for a given sha1).
The rename phase can therefore use the same hash data as
break. Unfortunately, we were throwing this data away after
computing it in the break phase. This patch instead attaches
it to the filespec and lets it live through the rename
phase, working under the assumption that most of the time
that breaks are being computed, renames will be too.
We only do this optimization for files which have actually
been broken, as those ones will be candidates for rename
detection (and it is a time-space tradeoff, so we don't want
to waste space keeping useless data).

consider breaking all of the other files. Which means that
both versions of every file you are diffing are in memory at
the same time.
This patch instead frees the blob data as we finish with
each file pair, leading to much lower memory usage.

As we look at each changed file and consider breaking it, we
load the blob data and make a decision about whether to
break, which is independent of any other blobs that might
have changed. However, we keep the data in memory while we
consider breaking all of the other files. Which means that
both versions of every file you are diffing are in memory at
the same time.

Makefile: Ensure rpm packages can be read by older rpm versions
The kernel.org hosts where the packages are built are now using Fedora
11, which defaults to sha256 for file digests instead of md5. Older
versions of rpm can not handle these packages. Tell rpmbuild to use md5
file digests for better compatibility.

give priority to progress messages
In theory it is possible for sideband channel #2 to be delayed if
pack data is quick to come up for sideband channel #1. And because
data for channel #2 is read only 128 bytes at a time while pack data
is read 8192 bytes at a time, it is possible for many pack blocks to
be sent to the client before the progress message fifo is emptied,
making the situation even worse. This would result in totally garbled
progress display on the client's console as local progress gets mixed
with partial remote progress lines.
Let's prevent such situations by giving transmission priority to
progress messages over pack data at all times.
