merge-tree: fix typo in merge-tree.c::unresolved
git-commit doc: describe use of multiple `-m` options
git-pull doc: fix grammo ("conflicts" is plural)
When calculating whether there is a d/f conflict, the calculation of
whether both sides are directories generates an incorrect references
mask because it does not use the loop index to set the correct bit.
Fix this typo.

Teach "diff --cc" output to honor options to ignore various forms

* ap/combine-diff-ignore-whitespace:
Allow combined diff to ignore white-spaces
In checkout_paths() we do this
- for all updated items, call match_pathspec
- for all items, call match_pathspec (inside unmerge_cache)
- for all items, call match_pathspec (for showing "path .. is unmerged)
- for updated items, call match_pathspec and update paths
That's a lot of duplicate match_pathspec(s) and the function is not
exactly cheap to be called so many times, especially on large indexes.
This patch makes it call match_pathspec once per updated index entry,
save the result in ce_flags and reuse the results in the following
loops.
The changes in 0a1283b (checkout $tree $path: do not clobber local
changes in $path not in $tree - 2011-09-30) limit the affected paths
to ones we read from $tree. We do not do anything to other modified
entries in this case, so the "for all items" above could be modified
to "for all updated items". But..
The command's behavior now is modified slightly: unmerged entries that
match $path, but not updated by $tree, are now NOT touched. Although
this should be considered a bug fix, not a regression. A new test is
added for this change.
And while at there, free ps_matched after use.
The following command is tested on webkit, 215k entries. The pattern
is chosen mainly to make match_pathspec sweat:
git checkout -- "*[a-zA-Z]*[a-zA-Z]*[a-zA-Z]*"
before after
real 0m3.493s 0m2.737s
user 0m2.239s 0m1.586s
sys 0m1.252s 0m1.151s

If two processes are racing to create the same directory tree, they
will both see that the directory doesn't exist, both try to mkdir(),
and one of them will fail. This is okay, as we only care that the
directory gets created. So, we add a check for EEXIST from mkdir,
and continue when the directory exists, taking the same codepath as
the case where the earlier stat() succeeds and finds a directory.

The function takes two strings (pathname and basename) as if they
are independent strings, but in reality, the latter is always
pointing into a substring in the former.

packed_object_info() and packed_delta_info() were mutually recursive.
The former would handle ordinary types and defer deltas to the latter;
the latter would use the former to resolve the delta base.
This arrangement, however, leads to trouble with threaded index-pack
and long delta chains on platforms where thread stacks are small, as
happened on OS X (512kB thread stacks by default) with the chromium
repo.
The task of the two functions is not all that hard to describe without
any recursion, however. It proceeds in three steps:
- determine the representation type and size, based on the outermost
object (delta or not)
- follow through the delta chain, if any
- determine the object type from what is found at the end of the delta
chain
The only complication stems from the error recovery. If parsing fails
at any step, we want to mark that object (within the pack) as bad and
try getting the corresponding SHA1 from elsewhere. If that also
fails, we want to repeat this process back up the delta chain until we
find a reasonable solution or conclude that there is no way to
reconstruct the object. (This is conveniently checked by t5303.)
To achieve that within the pack, we keep track of the entire delta
chain in a stack. When things go sour, we process that stack from the
top, marking entries as bad and attempting to re-resolve by sha1. To
avoid excessive malloc(), the stack starts out with a small
stack-allocated array. The choice of 64 is based on the default of
pack.depth, which is 50, in the hope that it covers "most" delta
chains without any need for malloc().
It's much harder to make the actual re-resolving by sha1 nonrecursive,
so we skip that. If you can't afford *that* recursion, your
corruption problems are more serious than your stack size problems.

Commit ba3c69a9 (commit: teach --gpg-sign option, 2011-10-05) added the
-S option but documented it in the command usage without indicating that
the value is optional and forgot to mention it in the manpage. Later
commit 098bbdc3 (Add -S, --gpg-sign option to manpage of "git commit",
2012-10-21) documented the option in the porcelain manpage.
Use wording from the porcelain manpage to document the option in the
plumbing manpage. Also update the commit-tree usage summary to indicate
that the -S value is optional to be consistent with the manpage and with
the implementation.

When core.sharedRepository is used, set_shared_perm() in path.c
needs lstat() to return the correct POSIX permissions.
The default for cygwin is core.ignoreCygwinFSTricks = false, which
means that the fast implementation in do_stat() is used instead of
lstat().
lstat() under cygwin uses the Windows security model to implement
POSIX-like permissions. The user, group or everyone bits can be set
individually.
do_stat() simplifes the file permission bits, and may return a wrong
value. The read-only attribute of a file is used to calculate the
permissions, resulting in either rw-r--r-- or r--r--r--
One effect of the simplified do_stat() is that t1301 fails.
Add a function cygwin_get_st_mode_bits() which returns the POSIX
permissions. When not compiling for cygwin, true_mode_bits() in
path.c is used.
Side note:
t1301 passes under cygwin 1.5.
The "user write" bit is synchronized with the "read only" attribute
of a file:
$ chmod 444 x
$ attrib x
A R C:\temp\pt\x
cygwin 1.7 would show
A C:\temp\pt\x

This replaces the greedy implementation to coalesce lost lines by using
dynamic programming to find the Longest Common Subsequence.
The O(n²) time complexity is obviously bigger than previous
implementation but it can produce shorter diff results (and most likely
easier to read).
List of lost lines is now doubly-linked because we reverse-read it when
reading the direction matrix.
