When we figure out how many file descriptors to allocate for

John Keeping bb3f45838b rebase: fix fork-point with zero arguments
When no arguments are specified, $switch_to is empty so we end up
passing the empty string to "git merge-base --fork-point", which causes
an error.  git-rebase carries on at this point, but in fact we have
failed to apply the fork-point operation.

It turns out that the test in t3400 that was meant to test this didn't
actually need the fork-point behaviour, so enhance it to make sure that
the fork-point is applied correctly.  The modified test fails without
the change to git-rebase.sh in this patch.

Nguyễn Thái Ngọc Duy 3b32a7ca90 t5537: fix incorrect expectation in test case 10
Commit 48d25ca adds a new commit "7" to the repo that the next test case
in commit 1609488 clones from. But the next test case does not expect
this commit. For these tests, it's the bottom that's important, not
the top. Fix the expected commit list.

While at it, fix the default http port number to 5537. Otherwise when
t5536 learns to test httpd, running test in parallel may fail.

Jens Lehmann bbad9f9314 rm: better document side effects when removing a submodule
The "Submodules" section of the "git rm" documentation mentions what will
happen when a submodule with a gitfile gets removed with newer git. But it
doesn't talk about what happens when the user changes between commits
before and after the removal, which does not remove the submodule from the
work tree like using the rm command did the first time.

Øystein Walle 2a07e4374c stash: handle specifying stashes with $IFS
When trying to pop/apply a stash specified with an argument
containing IFS whitespace, git-stash will throw an error:

    $ git stash pop 'stash@{two hours ago}'
    Too many revisions specified: stash@{two hours ago}

This happens because word splitting is used to count non-option
arguments. Make use of rev-parse's --sq option to quote the arguments
for us to ensure a correct count. Add quotes where necessary.

Also add a test that verifies correct behaviour.

Brodie Rao 832cf74c07 sha1_name: don't resolve refs when core.warnambiguousrefs is false
When seeing a full 40-hex object name, get_sha1_basic()
unconditionally checks if the string can also be interpreted as a
refname, but the result will not be used unless warn_ambiguous_refs
is in effect.

Omitting this unnecessary ref resolution provides a substantial
performance improvement, especially when passing many hashes to a
command (like "git rev-list --stdin") and core.warnambiguousrefs is
set to false.  The check incurs 6 stat()s for every hash supplied,
which can be costly over NFS.

Jonathan Nieder e54c1f2d25 pager: set LV=-c alongside LESS=FRSX
On systems with lv configured as the preferred pager (i.e.,
DEFAULT_PAGER=lv at build time, or PAGER=lv exported in the
environment) git commands that use color show control codes instead of
color in the pager:

	$ git diff
	^[[1mdiff --git a/.mailfilter b/.mailfilter^[[m
	^[[1mindex aa4f0b2..17e113e 100644^[[m
	^[[1m--- a/.mailfilter^[[m
	^[[1m+++ b/.mailfilter^[[m
	^[[36m@@ -1,11 +1,58 @@^[[m

"less" avoids this problem because git uses the LESS environment
variable to pass the -R option ('output ANSI color escapes in raw
form') by default.  Use the LV environment variable to pass 'lv' the
-c option ('allow ANSI escape sequences for text decoration / color')
to fix it for lv, too.

Noticed when the default value for color.ui flipped to 'auto' in
v1.8.4-rc0~36^2~1 (2013-06-10).

Francesco Pretto efa8fd7ee8 git-submodule.sh: 'checkout' is a valid update mode
'checkout' is documented as one of the valid values for the
'submodule.<name>.update' variable, and in a repository with the
variable set to 'checkout', "git submodule update" command does
update using the 'checkout' mode.

However, it has been an accident that the implementation works this
way; any unknown value would trigger the same codepath and update
using the 'checkout' mode.

Explicitly list 'checkout' as one of the known update modes, and
error out when an unknown update mode is used.

Teach the codepath that initializes the configuration variable from
an in-tree .gitmodules that 'checkout' is one of the valid values.
The code since ac1fbbda (submodule: do not copy unknown update mode
from .gitmodules, 2013-12-02) used to treat the value 'checkout' as
unknown and mapped it to 'none', which made little sense.  With this
change, 'checkout' specified in .gitmodules will stay to be 'checkout'.

Michael Haggerty 18d37e860d safe_create_leading_directories(): add new error value SCLD_VANISHED
Add a new possible error result that can be returned by
safe_create_leading_directories() and
safe_create_leading_directories_const(): SCLD_VANISHED.  This value
indicates that a file or directory on the path existed at one point
(either it already existed or the function created it), but then it
disappeared.  This probably indicates that another process deleted the
directory while we were working.  If SCLD_VANISHED is returned, the
caller might want to retry the function call, as there is a chance
that a new attempt will succeed.

Why doesn't safe_create_leading_directories() do the retrying
internally?  Because an empty directory isn't really ever safe until
it holds a file.  So even if safe_create_leading_directories() were
absolutely sure that the directory existed before it returned, there
would be no guarantee that the directory still existed when the caller
tried to write something in it.

Michael Haggerty bf10cf70ad safe_create_leading_directories(): split on first of multiple slashes
If the input path has multiple slashes between path components (e.g.,
"foo//bar"), then the old code was breaking the path at the last
slash, not the first one.  So in the above example, the second slash
was overwritten with NUL, resulting in the parent directory being
sought as "foo/".

When stat() is called on "foo/", it fails with ENOTDIR if "foo" exists
but is not a directory.  This caused the wrong path to be taken in the
subsequent logic.

So instead, split path components at the first intercomponent slash
rather than the last one.
