The paragraph to encourage use of "--" in scripts belongs to the

t0060: split absolute path test in two to exercise some of it on Windows
Only the first half of the test works only on POSIX, the second half
passes on Windows as well.
A later test "real path removes other extra slashes" looks very similar,
but it does not make sense to split it in the same way: When two slashes
are prepended in front of an absolute DOS-style path on Windows, the
meaning of the path is changed (//server/share style), so that the test
cannot pass on Windows.

HP NonStop does provide struct itimerval, but other platforms may
not, so this is taken care of in this commit too, by setting

path.c: Use vsnpath() in the implementation of git_path()
The current implementation of git_path() is essentially the same as
that of vsnpath(), with two minor differences. First, git_path()
currently insists that the git directory path is no longer than
PATH_MAX-100 characters in length. However, vsnpath() does not
attempt this arbitrary 100 character reservation for the remaining
path components. Second, vsnpath() uses the "is_dir_sep()" macro,
rather than comparing directly to '/', to determine if the git_dir
path component ends with a path separator.
In order to benefit from the above improvements, along with increased
compatability with git_snpath() and git_pathdup(), we reimplement the
git_path() function using vsnpath().

path.c: Don't discard the return value of vsnpath()

function vsnpath() in their implementation. Also, they both discard
the return value of vsnpath(), which has the effect of ignoring the
side effect of calling cleanup_path() in the non-error return path.
In order to ensure that the required cleanup happens, we use the
pointer returned by vsnpath(), rather than the buffer passed into
vsnpath(), to derive the return value from git_snpath() and
git_pathdup().

submodule: use argv_array instead of hand-building arrays
fetch_populated_submodules() allocates the full argv array it uses to
recurse into the submodules from the number of given options plus the six
argv values it is going to add. It then initializes it with those values
which won't change during the iteration and copies the given options into
it. Inside the loop the two argv values different for each submodule get
replaced with those currently valid.
However, this technique is brittle and error-prone (as the comment to
explain the magic number 6 indicates), so let's replace it with an
argv_array. Instead of replacing the argv values, push them to the
argv_array just before the run_command() call (including the option
separating them) and pop them from the argv_array right after that.

fetch: use argv_array instead of hand-building arrays
Fetch invokes itself recursively when recursing into

builds the child's command line by pushing options onto a

currently just big enough to handle the largest possible
case. However, this technique is brittle and error-prone, so
let's replace it with a dynamic argv_array.
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
Since the array struct stores a "const char **" argv member
(for compatibility with most of our argv-taking functions),
we have to cast away the const-ness when freeing its
elements.
However, we used the wrong type when doing so. It doesn't
make a difference since free() take a void pointer anyway,
but it can be slightly confusing to a reader.

Sometimes we build a set of similar command lines, differing
only in the final arguments (e.g., "fetch --multiple"). To
use argv_array for this, you have to either push the same
set of elements repeatedly, or break the abstraction by
manually manipulating the array's internal members.
Instead, let's provide a sanctioned "pop" function to remove
elements from the end.

$
This is due to the 'trailing_plan' having a 'skip_directive'
attached to it. This is not allowed by the TAP grammar, which
only allows a 'leading_plan' to be followed by an optional
'skip_directive'. (see perldoc TAP::Parser::Grammar).
A trailing_plan is one that appears in the TAP output after one or
more test status lines (that start 'not '? 'ok ' ...), whereas a
leading_plan must appear before all test status lines (if any).
In practice, this means that the test script cannot contain a use
of the 'skip all' facility:
skip_all='Some reason to skip *all* tests in this file'
test_done
after having already executed one or more tests with (for example)
'test_expect_success'. Unfortunately, this is exactly what this
test script is doing. The first 'setup' test is actually used to
determine if the test prerequisite is satisfied by the filesystem
(ie does it allow tabs in filenames?).
In order to fix the parse errors, place the code to determine the
test prerequisite at the top level of the script, prior to the
first test, rather than as a parameter to test_expect_success.
This allows us to correctly use 'skip_all', thus:
$ ./t3300-funny-names.sh
# passed all 0 test(s)
1..0 # SKIP Your filesystem does not allow tabs in filenames
$
$ prove --exec sh t3300-funny-names.sh

When fed such a commit, --format='%ci' fails to parse it, and gives

reduce_heads(): reimplement on top of remove_redundant()
This is used by "git merge" and "git merge-base --independent" but
used to use a similar N*(N-1) traversals to reject commits that are
ancestors of other commits.
Reimplement it on top of remove_redundant(). Note that the callers
of this function are allowed to pass the same commit more than once,
but remove_redundant() is designed to be fed each commit only once.
The function removes duplicates before calling remove_redundant().
get_merge_bases_many(): walk from many tips in parallel
The get_merge_bases_many() function reduces the result returned by
the merge_bases_many() function, which is a set of possible merge
bases, by excluding commits that can be reached from other commits.
We used to do N*(N-1) traversals for this, but we can check if one
commit reaches which other (N-1) commits by a single traversal, and
repeat it for all the candidates to find the answer.
Introduce remove_redundant() helper function to do this painting; we
should be able to use it to reimplement reduce_heads() as well.
With paint_down_to_common(), we can tell if "commit" is reachable
from "reference" by simply looking at its object flag, instead of
iterating over the merge bases.
merge_bases_many(): split out the logic to paint history
Introduce a new helper function paint_down_to_common() that takes
the same parameters as merge_bases_many(), but without the first
optimization of not painting anything when "one" is one of the
"twos" (or vice versa), and the last clean-up of removing the common
ancestor that is known to be an ancestor of another common one.
This way, the caller of the new function could tell if "one" is
reachable from any of the "twos" by simply looking at the flag bits
of "one". If (and only if) it is painted in PARENT2, it is
reachable from one of the "twos".
cherry-pick/revert: respect order of revisions to pick
When giving multiple individual revisions to cherry-pick or revert, as
in 'git cherry-pick A B' or 'git revert B A', one would expect them to
be picked/reverted in the order given on the command line. They are
instead ordered by their commit timestamp -- in chronological order
for "cherry-pick" and in reverse chronological order for
"revert". This matches the order in which one would usually give them
on the command line, making this bug somewhat hard to notice. Still,
it has been reported at least once before [1].
It seems like the chronological sorting happened by accident because
the revision walker has traditionally always sorted commits in reverse
chronological order when rev_info.no_walk was enabled. In the case of
'git revert B A' where B is newer than A, this sorting is a no-op. For
'git cherry-pick A B', the sorting would reverse the arguments, but
because the sequencer also flips the rev_info.reverse flag when
picking (as opposed to reverting), the end result is a chronological
order. The rev_info.reverse flag was probably flipped so that the
revision walker emits B before C in 'git cherry-pick A..C'; that it
happened to effectively undo the unexpected sorting done when not
walking, was probably a coincidence that allowed this bug to happen at
all.
Fix the bug by telling the revision walker not to sort the commits
when not walking. The only case we want to reverse the order is now
when cherry-picking and walking revisions (rev_info.no_walk = 0).
teach log --no-walk=unsorted, which avoids sorting
When 'git log' is passed the --no-walk option, no revision walk takes
place, naturally. Perhaps somewhat surprisingly, however, the provided
revisions still get sorted by commit date. So e.g 'git log --no-walk
HEAD HEAD~1' and 'git log --no-walk HEAD~1 HEAD' give the same result
(unless the two revisions share the commit date, in which case they
will retain the order given on the command line). As the commit that
introduced --no-walk (8e64006 (Teach revision machinery about
--no-walk, 2007-07-24)) points out, the sorting is intentional, to
allow things like
To accomodate both cases, leave the decision of whether or not to sort
up to the caller, by allowing --no-walk={sorted,unsorted}, defaulting
to 'sorted' for backward-compatibility reasons.

sh-setup: protect from exported IFS
Originally the "--quiet" option was parsed by the
diff-option parser into the internal QUICK option. This had
the effect of silencing diff output from the log (which was
not intended, but happened to work and people started to
use it). But it also had other odd side effects at the diff
level (for example, it would suppress the second commit in
"git show A B").
To fix this, commit 1c40c36 converted log to parse-options
and handled the "quiet" option separately, not passing it
on to the diff code. However, it simply ignored the option,
which was a regression for people using it as a synonym for
"-s". Commit 01771a8 then fixed that by interpreting the
option to add DIFF_FORMAT_NO_OUTPUT to the list of output
formats.
However, that commit did not fix it in all cases. It sets
the flag after setup_revisions is called. Naively, this
makes sense because you would expect the setup_revisions
parser to overwrite our output format flag if "-p" or
another output format flag is seen.
However, that is not how the NO_OUTPUT flag works. We
actually store it in the bit-field as just another format.
At the end of setup_revisions, we call diff_setup_done,
which post-processes the bitfield and clears any other
formats if we have set NO_OUTPUT. By setting the flag after
setup_revisions is done, diff_setup_done does not have a
chance to make this tweak, and we end up with other format
options still set.
As a result, the flag would have no effect in "git log -p
--quiet" or "git show --quiet". Fix it by setting the
format flag before the call to setup_revisions.

in_merge_bases(): omit unnecessary redundant common ancestor reduction
