1123c67cee accept "git grep -- pattern"
Currently the only way to "quote" a grep pattern that might
begin with a dash is to use "git grep -e pattern". This
works just fine, and is also the way right way to do it on
many traditional grep implemenations.

Some people prefer to use "git grep -- pattern", however, as
"--" is the usual "end of options" marker, and at least GNU
grep and Solaris 10 grep support this. This patch makes that
syntax work.

There is a slight behavior change, in that "git grep -- $X"
used to be interpreted as "grep for -- in $X". However, that
usage is questionable. "--" is usually the end-of-options
marker, so "git grep" was unlike many other greps in
treating it as a literal pattern (e.g., both GNU grep and
Solaris 10 grep will treat "grep --" as missing a pattern).

fe12d8e84f archive: simplify archive format guessing
The code to guess an output archive's format consumed any --format
options and built a new one.  Jonathan noticed that it does so in an
unsafe way, risking to overflow the static buffer fmt_opt.

Change the code to keep the existing --format options intact and to only
add a new one if a format could be guessed based on the output file name.
The new option is added as the first one, allowing the existing ones to
overrule it, i.e. explicit --format options given on the command line win
over format guesses, as before.

To simplify the code further, format_from_name() is changed to return the
full --format option, thus no potentially dangerous sprintf() calls are
needed any more.

8424981934 Fix invalid read in quote_c_style_counted
This function did not work on strings that were not NUL-terminated. It
reads through a length-bounded string, searching for characters in need of
quoting. After we find one, we output the quoted character, then advance
our pointer to find the next one. However, we never decremented the
length, meaning we ended up looking at whatever random junk was stored
after the string.

This bug was not found by the existing tests because most code paths feed
a NUL-terminated string. The notable exception is a directory name being
fed by ls-tree.

ab35469de0 t9501: Re-fix max load test
Revert the previous attempt to skip this test on platforms where we
currently cannot determine the system load.  We want to make sure that
the max-load-limit codepath produces results cleanly, when gitweb is
updated and becomes capable of reading the load average by some other
method.

The code to check for load returns 0 if it doesn't know how to find
load.  It also checks to see if the current load is higher than the
max load.  So to force the script to quit early by setting the maxload
variable negative which should work for systems where we can detect
load (which should be a positive number) and systems where we can't
(where detected load is 0)

6d525d389f receive-pack: Send hook output over side band #2
If the client requests to enable side-band-64k capability we can
safely send any hook stdout or stderr data down side band #2,
so the client can present it to the user.

If side-band-64k isn't enabled, hooks continue to inherit stderr
from the parent receive-pack process.

When the side band channel is being used the push client will wind up
prefixing all server messages with "remote: ", just like fetch does,
so our test vector has to be updated with the new expected output.

07cf0f2407 make --max-pack-size argument to 'git pack-object' count in bytes
The value passed to --max-pack-size used to count in MiB which was
inconsistent with the corresponding configuration variable as well as
other command arguments which are defined to count in bytes with an
optional unit suffix.  This brings --max-pack-size in line with the
rest of Git.

Also, in order not to cause havoc with people used to the previous
megabyte scale, and because this is a sane thing to do anyway, a
minimum size of 1 MiB is enforced to avoid an explosion of pack files.

2fca19fbb5 fix multiple issues with t5300
First of all, trying to run 'git verify-pack' on packs  produced by
the tests using pack.packSizeLimit always failed.  After lots of digging
and head scratching, it turns out that the preceeding test simulating
a SHA1 collision did leave the repository quite confused, impacting
subsequent tests.

So let's move that destructive test last, and add tests to run
verify-pack on the output from those packSizeLimit tests to catch such
goofage.

Finally, group those packSizeLimit tests together.

b62a1a98bc gitweb: Load checking
This changes slightly the behavior of gitweb, so that it verifies
that the box isn't inundated with before attempting to serve gitweb.
If the box is overloaded, it basically returns a 503 Server Unavailable
until the load falls below the defined threshold.  This helps dramatically
if you have a box that's I/O bound, reaches a certain load and you
don't want gitweb, the I/O hog that it is, increasing the pain the
server is already undergoing.

This behavior is controlled by $maxload configuration variable.
Default is a load of 300, which for most cases should never be hit.
Unset it (set it to undefined value, i.e. undef) to turn off checking.

Currently it requires that '/proc/loadavg' file exists, otherwise the
load check is bypassed (load is taken to be 0).  So platforms that do
not implement '/proc/loadavg' currently cannot use this feature
(provisions are included for additional checks to be added by others).

There is simple test in t/t9501-gitweb-standalone-http-status.sh to
check that it correctly returns "503 Service Unavailable" if load is
too high, and also if there are any Perl warnings or errors.

Remove test_debug lines after 'snapshots: tgz only default format
enabled' and 'snapshots: all enabled in default, use default disabled
value' tests.  Those tests constitute of multiple gitweb_run
invocation, therefore outputting gitweb.output for the last gitweb_run
wouldn't help much in debugging test failure, and can only confuse.

For snapshot tests which check for "200 OK" status, change
  test_debug 'cat gitweb.output'
to
  test_debug 'cat gitweb.headers'
Otherwise when running this test with '--debug' option,
t/t9501-gitweb-standalone-http-status.sh would dump *binary data* (the
snapshot itself) to standard output, which can mess up state of terminal
due to term control characters which can be embedded in output.

13be3e31f1 Reword "detached HEAD" notification
The old "advice" message explained how to create a branch after going into
a detached HEAD state but didn't make it clear why the user may want to do
so.  Also "moving to ... which isn't a local branch" was unclear if it is
complaining, if it is describing the new state, or if it is explaining why
the HEAD is detached (the true reason is the last one).

Give the established phrase 'detached HEAD' first to make it easy for
users to look up the concept in documentation, and briefly describe what
can be done in the state (i.e. play around without having to clean up)
before telling the user how to keep what was done during the temporary
state.

Allow the long description to be hidden by setting advice.detachedHead
configuration to false.

We might want to customize the advice depending on how the commit to check
out was spelled (e.g. instead of "new-branch-name", we way want to say
"topic" when "git checkout origin/topic" triggered this message) in later
updates, but this encapsulates that into a separate function and it should
be a good first step.

2) it is possible to replace submodule revision by direct index

93cfa7c7a8 approxidate_careful() reports errorneous date string
For a long time, the time based reflog syntax (e.g. master@{yesterday})
didn't complain when the "human readable" timestamp was misspelled, as
the underlying mechanism tried to be as lenient as possible.  The funny
thing was that parsing of "@{now}" even relied on the fact that anything
not recognized by the machinery returned the current timestamp.

Introduce approxidate_careful() that takes an optional pointer to an
integer, that gets assigned 1 when the input does not make sense as a
timestamp.

As I am too lazy to fix all the callers that use approxidate(), most of
the callers do not take advantage of the error checking, but convert the
code to parse reflog to use it as a demonstration.

80235ba79e "log --author=me --grep=it" should find intersection, not union
Historically, any grep filter in "git log" family of commands were taken
as restricting to commits with any of the words in the commit log message.
However, the user almost always want to find commits "done by this person
on that topic".  With "--all-match" option, a series of grep patterns can
be turned into a requirement that all of them must produce a match, but
that makes it impossible to ask for "done by me, on either this or that"
with:

	log --author=me --committer=him --grep=this --grep=that

because it will require both "this" and "that" to appear.

Change the "header" parser of grep library to treat the headers specially,
and parse it as:

	(all-match-OR (HEADER-AUTHOR me)
		      (HEADER-COMMITTER him)
		      (OR
		      	(PATTERN this)
			(PATTERN that) ) )

Even though the "log" command line parser doesn't give direct access to
the extended grep syntax to group terms with parentheses, this change will
cover the majority of the case the users would want.

This incidentally revealed that one test in t7002 was bogus.  It ran:

	log --author=Thor --grep=Thu --format='%s'

and expected (wrongly) "Thu" to match "Thursday" in the author/committer
date, but that would never match, as the timestamp in raw commit buffer
does not have the name of the day-of-the-week.

append_cr(), remove_cr(), q_to_nul() and q_to_cr() are defined in multiple
tests. Consolidate them into test-lib.sh so we can stop redefining them.
The use of remove_cr() in t0020 to test for a CR is replaced with a new
function has_cr() to accurately reflect what is intended (the output of
remove_cr() was being thrown away).

9567f082dd t5541-http-push: make grep expression check for one line only
Don't feed a multiple-line pattern to grep and expect the them to match
with lines in order.

Simplify the grep expressions in the non-fast-forward tests to check
only for the first line of the non-fast-forward warning - having that
line should be enough assurance that the full warning is printed.

ffbc5dc2d0 reset: add test cases for "--keep" option
This shows that with the "--keep" option, changes that are both in
the work tree and the index are kept in the work tree after the
reset (but discarded in the index).

In the case of unmerged entries, we can see that "git reset --keep"
works only when the target state is the same as HEAD. And then the
work tree is not reset.

075762085c git-svn: allow subset of branches/tags to be specified in glob spec
For very large projects it is useful to be able to clone a subset of the
upstream SVN repo's branches. Allow for this by letting the left-side of
the branches and tags glob specs contain a brace-delineated comma-separated
list of names. e.g.:

	branches = branches/{red,green}/src:refs/remotes/branches/*

3e18ce1ac3 git-svn: allow UUID to be manually remapped via rewriteUUID
In certain situations it may be necessary to manually remap an svn
repostitory UUID. For example:

                  o--- [git-svn clone]
                 /
[origin svn repo]
                 \
                  o--- [svnsync clone]

Imagine that only "git-svn clone" and "svnsync clone" are made available
to external users. Furthur, "git-svn clone" contains only trunk, and for
reasons unknown, "svnsync clone" is missing the revision properties that
normally provide the origin svn repo's UUID.

A git user who has cloned the "git-svn clone" repo now wishes to use
git-svn to pull in the missing branches from the "synsync clone" repo.
In order for git-svn to get the history correct for those branches,
it needs to know the origin svn repo's UUID. Hence rewriteUUID.

The function takes two paths, an early part of abs is supposed to match
base; otherwise abs is not a path under base and the function returns the
full path of abs.  The caller can easily confuse the implementation by
giving duplicated and needless slashes in these path arguments.

The code used as if return value from basename(3) were stable, but
often the function is implemented to return a pointer to a static

Because basename(3) is also allowed to modify its input parameter in
place, casting constness away from the strings we obtained from the
caller and giving them to basename is a no-no.

66b2ed09c2 Fix "log" family not to be too agressive about showing notes
Giving "Notes" information in the default output format of "log" and
"show" is a sensible progress (the user has asked for it by having the
notes), but for some commands (e.g. "format-patch") spewing notes into the
formatted commit log message without being asked is too aggressive.

Enable notes output only for "log", "show", "whatchanged" by default and
only when the user didn't ask any specific --pretty/--format from the
command line; users can explicitly override this default with --show-notes
and --no-notes option.

Parts of tests are taken from Jeff King's fix.

ae0ba8e20a Teach @{upstream} syntax to strbuf_branchanme()
This teaches @{upstream} syntax to interpret_branch_name(), instead
of dwim_ref() machinery.

There are places in git UI that behaves differently when you give a local
branch name and when you give an extended SHA-1 expression that evaluates
to the commit object name at the tip of the branch.  The intent is that
the special syntax such as @{-1} can stand in as if the user spelled the
name of the branch in such places.

The name of the branch "frotz" to switch to ("git checkout frotz"), and
the name of the branch "nitfol" to fork a new branch "frotz" from ("git
checkout -b frotz nitfol"), are examples of such places.  These places
take only the name of the branch (e.g. "frotz"), and they are supposed to
act differently to an equivalent refname (e.g. "refs/heads/frotz"), so
hooking the @{upstream} and @{-N} syntax to dwim_ref() is insufficient
when we want to deal with cases a local branch is forked from another
local branch and use "forked@{upstream}" to name the forkee branch.

The "upstream" syntax "forked@{u}" is to specify the ref that "forked" is
configured to merge with, and most often the forkee is a remote tracking
branch, not a local branch.  We cannot simply return a local branch name,
but that does not necessarily mean we have to returns the full refname
(e.g. refs/remotes/origin/frotz, when returning origin/frotz is enough).
This update calls shorten_unambiguous_ref() to do so.

8de65185e8 Fix mis-backport of t7002
The original patch that became cfe370c (grep: do not segfault when -f is
used, 2009-10-16), was made against "maint" or newer branch back then, but
the fix addressed the issue that was present as far as in 1.6.4 series.

The maintainer backported the patch to the 1.6.4 maintenance branch, but
failed to notice that the new tests assumed the setup done by the script
in "maint", which did quite a lot more than the same test script in 1.6.4
series, and the output didn't match the expected result.

This should fix it.

f17a5d3494 git status: Show uncommitted submodule changes too when enabled
When the configuration variable status.submodulesummary is not 0 or
false, "git status" shows the submodule summary of the staged submodule
commits. But it did not show the summary of those commits not yet
staged in the supermodule, making it hard to see what will not be
committed.

The output of "submodule summary --for-status" has been changed from
"# Modified submodules:" to "# Submodule changes to be committed:" for
the already staged changes. "# Submodules changed but not updated:" has
been added for changes that will not be committed. This is much clearer
and consistent with the output for regular files.

Until now a submodule only then showed up as modified in the supermodule
when the last commit in the submodule differed from the one in the index
or the diffed against commit of the superproject. A dirty work tree
containing new untracked or modified files in a submodule was
undetectable when looking at it from the superproject.

Now git status and git diff (against the work tree) in the superproject
will also display submodules as modified when they contain untracked or
modified files, even if the compared ref matches the HEAD of the
submodule.

e8189ee90e Test t5560: Fix test when run with dash
A command invocation preceded by variable assignments, i.e.

	VAR1=VAL1 VAR2=VAL2 ... command args

are implemented by dash and ksh in such a way not to export these
variables, and keep the values after the command finishes, when the
command is a shell function.  POSIX.1 "2.9.5 Function Definition Command"
specifies this behaviour.

Many shells however treat this construct the same way as they are calling
external commands.  They export the variables during the duration of
command, and resets their values after command returns.

The test relied on the behaviour of the latter kind.

49ff9a7a02 commit: show interesting ident information in summary
There are a few cases of user identity information that we consider
interesting:

  (1) When the author and committer identities do not match.

  (2) When the committer identity was picked automatically from the
      username, hostname and GECOS information.

In these cases, we already show the information in the commit
message template. However, users do not always see that template
because they might use "-m" or "-F". With this patch, we show these
interesting cases after the commit, along with the subject and
change summary. The new output looks like:

  $ git commit \
      -m "federalist papers" \
      --author='Publius <alexander@hamilton.com>'
  [master 3d226a7] federalist papers
   Author: Publius <alexander@hamilton.com>
   1 files changed, 1 insertions(+), 0 deletions(-)

for case (1), and:

  $ git config --global --unset user.name
  $ git config --global --unset user.email
  $ git commit -m foo
  [master 7c2a927] foo
   Committer: Jeff King <peff@c-71-185-130-222.hsd1.va.comcast.net>
  Your name and email address were configured automatically based
  on your username and hostname. Please check that they are accurate.
  You can suppress this message by setting them explicitly:

      git config --global user.name Your Name
      git config --global user.email you@example.com

  If the identity used for this commit is wrong, you can fix it with:

      git commit --amend --author='Your Name <you@example.com>'

0a0416a34a strbuf_expand: convert "%%" to "%"
The only way to safely quote arbitrary text in a pretty-print user
format is to replace instances of "%" with "%x25". This is slightly
unreadable, and many users would expect "%%" to produce a single
"%", as that is what printf format specifiers do.

This patch converts "%%" to "%" for all users of strbuf_expand():

 (1) git-daemon interpolated paths

 (2) pretty-print user formats

 (3) merge driver command lines

Case (1) was already doing the conversion itself outside of
strbuf_expand(). Case (2) is the intended beneficiary of this patch.
Case (3) users probably won't notice, but as this is user-facing
behavior, consistently providing the quoting mechanism makes sense.

When a squash/fixup fails due to a conflict, the user is required to
edit the commit message.  Previously, if further squash/fixup commands

discarded and a new automatically-generated commit message was
suggested.

Change the handling of conflicts within squash/fixup command series:
Whenever the user is required to intervene, consider the resulting
commit to be a new basis for the following squash/fixups and use its

28fb84382b Introduce <branch>@{upstream} notation
A new notation '<branch>@{upstream}' refers to the branch <branch> is set
to build on top of.  Missing <branch> (i.e. '@{upstream}') defaults to the
current branch.

This allows you to run, for example,

	for l in list of local branches
	do
		git log --oneline --left-right $l...$l@{upstream}
	done

to inspect each of the local branches you are interested in for the
divergence from its upstream.

d38a30df7d Be more user-friendly when refusing to do something because of conflict.
Various commands refuse to run in the presence of conflicts (commit,
merge, pull, cherry-pick/revert). They all used to provide rough, and
inconsistant error messages.

A new variable advice.resolveconflict is introduced, and allows more
verbose messages, pointing the user to the appropriate solution.

For commit, the error message used to look like this:

$ git commit
foo.txt: needs merge
foo.txt: unmerged (c34a92682e0394bc0d6f4d4a67a8e2d32395c169)
foo.txt: unmerged (3afcd75de8de0bb5076942fcb17446be50451030)
foo.txt: unmerged (c9785d77b76dfe4fb038bf927ee518f6ae45ede4)
error: Error building trees

The "need merge" line is given by refresh_cache. We add the IN_PORCELAIN
option to make the output more consistant with the other porcelain
commands, and catch the error in return, to stop with a clean error
message. The next lines were displayed by a call to cache_tree_update(),
which is not reached anymore if we noticed the conflict.

The new output looks like:

U       foo.txt
fatal: 'commit' is not possible because you have unmerged files.
Please, fix them up in the work tree, and then use 'git add/rm <file>' as
appropriate to mark resolution and make a commit, or use 'git commit -a'.

Pull is slightly modified to abort immediately if $GIT_DIR/MERGE_HEAD
exists instead of waiting for merge to complain.

The behavior of merge and the test-case are slightly modified to reflect
the usual flow: start with conflicts, fix them, and afterwards get rid of
MERGE_HEAD, with different error messages at each stage.

again.

08d63a422b transport-helper.c::push_refs(): ignore helper-reported status if ref is not to be pushed
If the status of a ref is REF_STATUS_NONE, the remote helper will not
be told to push the ref (via a 'push' command).

However, the remote helper may still act on these refs.

If the helper does act on the ref, and prints a status for it, ignore
the report (ie. don't overwrite the status of the ref with it, nor the
message in the remote_status member) if the reported status is 'no
match'.

This allows the user to be alerted to more "interesting" ref statuses,
like REF_STATUS_NONFASTFORWARD.

20e8b465a5 refactor ref status logic for pushing
Move the logic that detects up-to-date and non-fast-forward refs to a
new function in remote.[ch], set_ref_status_for_push().

Make transport_push() invoke set_ref_status_for_push() before invoking
the push_refs() implementation. (As a side-effect, the push_refs()
implementation in transport-helper.c now knows of non-fast-forward
pushes.)

Removed logic for detecting up-to-date refs from the push_refs()
implementation in transport-helper.c, as transport_push() has already
done so for it.

Make cmd_send_pack() invoke set_ref_status_for_push() before invoking
send_pack(), as transport_push() can't do it for send_pack() here.

Mark the test on the return status of non-fast-forward push to fail.
Git now exits with success, as transport.c::transport_push() does not
check for refs with status REF_STATUS_REJECT_NONFASTFORWARD nor does it
indicate rejected pushes with its return value.

Mark the test for ref status to succeed. As mentioned earlier, refs
might be marked as non-fast-forwards, triggering the push status
printing mechanism in transport.c.

48ffef966c ls-files: fix overeager pathspec optimization
Given pathspecs that share a common prefix, ls-files optimized its call
into recursive directory reader by starting at the common prefix
directory.

If you have a directory "t" with an untracked file "t/junk" in it, but the
top-level .gitignore file told us to ignore "t/", this resulted in:

    $ git ls-files -o --exclude-standard
    $ git ls-files -o --exclude-standard t/
    t/junk
    $ git ls-files -o --exclude-standard t/junk
    t/junk
    $ cd t && git ls-files -o --exclude-standard
    junk

We could argue that you are overriding the ignore file by giving a
patchspec that matches or being in that directory, but it is somewhat
unexpected.  Worse yet, these behave differently:

    $ git ls-files -o --exclude-standard t/ .
    $ git ls-files -o --exclude-standard t/
    t/junk

This patch changes the optimization so that it notices when the common
prefix directory that it starts reading from is an ignored one.

730f72840c unpack-trees.c: look ahead in the index
This makes the traversal of index be in sync with the tree traversal.
When unpack_callback() is fed a set of tree entries from trees, it
inspects the name of the entry and checks if the an index entry with
the same name could be hiding behind the current index entry, and

 (1) if the name appears in the index as a leaf node, it is also
     fed to the n_way_merge() callback function;

 (2) if the name is a directory in the index, i.e. there are entries in
     that are underneath it, then nothing is fed to the n_way_merge()
     callback function;

 (3) otherwise, if the name comes before the first eligible entry in the
     index, the index entry is first unpacked alone.

When traverse_trees_recursive() descends into a subdirectory, the
cache_bottom pointer is moved to walk index entries within that directory.

All of these are omitted for diff-index, which does not even want to be
fed an index entry and a tree entry with D/F conflicts.

This fixes 3-way read-tree and exposes a bug in other parts of the system
in t6035, test #5.  The test prepares these three trees:

 O = HEAD^
    100644 blob e69de29bb2    a/b-2/c/d
    100644 blob e69de29bb2    a/b/c/d
    100644 blob e69de29bb2    a/x

 A = HEAD
    100644 blob e69de29bb2    a/b-2/c/d
    100644 blob e69de29bb2    a/b/c/d
    100644 blob 587be6b4c3f93f93c489c0111bba5596147a26cb    a/x

 B = master
    120000 blob a36b77384451ea1de7bd340ffca868249626bc52    a/b
    100644 blob e69de29bb2    a/b-2/c/d
    100644 blob e69de29bb2    a/x

With a clean index that matches HEAD, running

    git read-tree -m -u --aggressive $O $A $B

now yields

    120000 a36b77384451ea1de7bd340ffca868249626bc52 3       a/b
    100644 e69de29bb2 0       a/b-2/c/d
    100644 e69de29bb2 1       a/b/c/d
    100644 e69de29bb2 2       a/b/c/d
    100644 587be6b4c3f93f93c489c0111bba5596147a26cb 0       a/x

which is correct.  "master" created "a/b" symlink that did not exist,
and removed "a/b/c/d" while HEAD did not do touch either path.

Before this series, read-tree did not notice the situation and resolved
addition of "a/b" and removal of "a/b/c/d" independently.  If A = HEAD had
another path "a/b/c/e" added, this merge should conflict but instead it
silently resolved "a/b" and then immediately overwrote it to add
"a/b/c/e", which was quite bogus.

Tests in t1012 start to work with this.

43015774c3 Smart-http tests: Improve coverage in test t5560
Commit 34b6cb8bb ("http-backend: Protect GIT_PROJECT_ROOT from /../
requests") added the path_info helper function to test t5560 but did
not use it.  We should use it as it provides another level of error
checking.

The /etc/.../passwd case is one that is not special (and the test
fails for reasons other than being aliased), so we remove that test
case.

Also rename the function from 'path_info' to 'expect_aliased'.

8b2bd7cdac Smart-http: check if repository is OK to export before serving it
Similar to how git-daemon checks whether a repository is OK to be
exported, smart-http should also check.  This check can be satisfied
in two different ways: the environmental variable GIT_HTTP_EXPORT_ALL
may be set to export all repositories, or the individual repository
may have the file git-daemon-export-ok.

0d344738dc t/lib-http.sh: Restructure finding of default httpd location
On CentOS 5, httpd is located at /usr/sbin/httpd, and the modules are
located at /usr/lib64/httpd/modules.  To enable easy testing of httpd,
we would like those locations to be detected automatically.

uname might not be the best way to determine the default location for
httpd since different Linux distributions apparently put httpd in
different places, so we test a couple different locations for httpd,
and use the first one that we come across.  We do the same for the
modules directory.

6396258368 t4030, t4031: work around bogus MSYS bash path conversion
Recall that MSYS bash converts POSIX style absolute paths to Windows style
absolute paths. Unfortunately, it converts a program argument that begins
with a double-quote and otherwise looks like an absolute POSIX path, but
in doing so, it strips everything past the second double-quote[*]. This
case is triggered in the two test scripts. The work-around is to place the
Windows style path returned by $(pwd) between the quotes to avoid the path
conversion.

[*] It is already bogus that a conversion is even considered when a program
argument begins with a double-quote because it cannot be an absolute POSIX
path.

41a457e4f8 textconv: use shell to run helper
Currently textconv helpers are run directly. Running through
the shell is useful because the user can provide a program
with command line arguments, like "antiword -f".

It also makes textconv more consistent with other parts of
git, most of which run their helpers using the shell.

The downside is that textconv helpers with shell
metacharacters (like space) in the filename will be broken.

fa7151a61e t0021: use $SHELL_PATH for the filter script
On Windows, we need the shbang line to correctly invoke shell scripts via
a POSIX shell, except when the script is invoked via 'sh -c' because sh (a
bash) does "the right thing".  But the clean and smudge filters will not
always be invoked via 'sh -c'; to futureproof, we should mark the the one
in t0021-conversion with #!$SHELL_PATH.

cee2d6ae63 Aggressive three-way merge: fix D/F case
When the ancestor used to have a blob "P", your tree removed it, and the
tree you are merging with also removed it, the agressive three-way cleanly
merges to remove that blob.  If the other tree added a new blob "P/Q"
while removing "P", it should also merge cleanly to remove "P" and create
"P/Q" (since neither the ancestor nor your tree could have had it, so it
is a typical "created in one").

The "aggressive" rule is not new anymore.  Reword the stale comment.

1ee26571e9 traverse_trees(): handle D/F conflict case sanely
traverse_trees() is supposed to call its callback with all the matching
entries from the given trees.  The current algorithm keeps a pointer to
each of the tree being traversed, and feeds the entry with the earliest
name to the callback.

This breaks down if the trees being traversed looks like this:

    A    B
    t-1  t
    t-2  u
    t/a  v

When we are currently looking at an entry "t-1" in tree A, and tree B has
returned "t", feeding "t" from the B and not feeding anything from A, only
because "t-1" sorts later than "t", will miss an entry for a subtree "t"
behind the current entry in tree A.

This introduces extended_entry_extract() helper function that gives what
name is expected from the tree, and implements a mechanism to look-ahead
in the tree object using it, to make sure such a case is handled sanely.
Traversal in tree A in the above example will first return "t" to match
that of B, and then the next request for an entry to A then returns "t-1".

This roughly corresponds to what Linus's "prepare for one-entry lookahead"
wanted to do, but because this does implement look ahead, t6035 and one more
test in t1012 reveal that the approach would not work without adjusting the
side that walks the index in unpack_trees() as well.

e11d7b5969 "reset --merge": fix unmerged case
Commit 9e8ecea (Add 'merge' mode to 'git reset', 2008-12-01) disallowed
"git reset --merge" when there was unmerged entries.  But it wished if
unmerged entries were reset as if --hard (instead of --merge) has been
used.  This makes sense because all "mergy" operations makes sure that
any path involved in the merge does not have local modifications before
starting, so resetting such a path away won't lose any information.

The previous commit changed the behavior of --merge to accept resetting
unmerged entries if they are reset to a different state than HEAD, but it
did not reset the changes in the work tree, leaving the conflict markers
in the resulting file in the work tree.

Fix it by doing three things:

 - Update the documentation to match the wish of original "reset --merge"
   better, namely, "An unmerged entry is a sign that the path didn't have
   any local modification and can be safely resetted to whatever the new
   HEAD records";

 - Update read_index_unmerged(), which reads the index file into the cache
   while dropping any higher-stage entries down to stage #0, not to copy
   the object name from the higher stage entry.  The code used to take the
   object name from the a stage entry ("base" if you happened to have
   stage #1, or "ours" if both sides added, etc.), which essentially meant
   that you are getting random results depending on what the merge did.

   The _only_ reason we want to keep a previously unmerged entry in the
   index at stage #0 is so that we don't forget the fact that we have
   corresponding file in the work tree in order to be able to remove it
   when the tree we are resetting to does not have the path.  In order to
   differentiate such an entry from ordinary cache entry, the cache entry
   added by read_index_unmerged() is marked as CE_CONFLICTED.

 - Update merged_entry() and deleted_entry() so that they pay attention to
   cache entries marked as CE_CONFLICTED.  They are previously unmerged
   entries, and the files in the work tree that correspond to them are
   resetted away by oneway_merge() to the version from the tree we are
   resetting to.

d0f379c2dc reset: use "unpack_trees()" directly instead of "git read-tree"
This patch makes "reset_index_file()" call "unpack_trees()" directly
instead of forking and execing "git read-tree". So the code is more
efficient.

And it's also easier to see which unpack_tree() options will be used,
as we don't need to follow "git read-tree"'s command line parsing
which is quite complex.

As Daniel Barkalow found, there is a difference between this new
version and the old one. The old version gives an error for
"git reset --merge" with unmerged entries, and the new version does
not when we reset the entries to some states that differ from HEAD.
Instead, it resets the index entry and succeeds, while leaving the
conflict markers in the corresponding file in the work tree (which
will be corrected by the next patch).

The code comes from the sequencer GSoC project:

4cefa495ca git-difftool: Add '--gui' for selecting a GUI tool
Users might prefer to have git-difftool use a different
tool when run from a Git GUI.

This teaches git-difftool to honor 'diff.guitool' when
the '--gui' option is specified.  This allows users to
configure their preferred command-line diff tool in
'diff.tool' and a GUI diff tool in 'diff.guitool'.

23218bbd2e t7800-difftool: Set a bogus tool for use by tests
If a difftool test has an error then running the git test suite
may end up invoking a GUI diff tool.  We now guard against this
by setting a difftool.bogus-tool.cmd variable.

The tests already used --tool=bogus-tool in various places so
this is simply ensuring that nothing ever falls back and
finds a real diff tool.
