ef45bb1f81 ll-merge: pass the original path to external drivers
The interface to custom low-level merge driver was modeled to be
capable of driving programs like "merge" (from the RCS suite) that
can produce result solely by looking at three files that hold
contents of common ancestor, ours and theirs.  The information we
feed to the external drivers via the command line placeholders %O,
%A, and %B were designed to be purely about contents by giving
names of the temporary files that hold these variants without
exposing the original pathname.  No matter where the result goes,
merging the same three variants should produce the same result,
contents is the king, that is the Git way.

The external driver interface, however, is meant to help people to
step outside the Git worldview, and sometimes people want to know
the final path that the resulting merged contents would be stored
in.  Expose this to the external drivers via a new placeholder %P.

d96a275b91 git-am: add am.threeWay config variable
Add the am.threeWay configuration variable to use the -3 or --3way
option of git am by default. When am.threeway is set and not desired
for a specific git am command, the --no-3way option can be used to

f0e7f11d05 index-pack: fix truncation of off_t in comparison
Commit c6458e6 (index-pack: kill union delta_base to save
memory, 2015-04-18) refactored the comparison functions used
in sorting and binary searching our delta list. The
resulting code does something like:

  int cmp_offsets(off_t a, off_t b)
  {
	  return a - b;
  }

This works most of the time, but produces nonsensical
results when the difference between the two offsets is
larger than what can be stored in an "int". This can lead to
unresolved deltas if the packsize is larger than 2G (even on
64-bit systems, an int is still typically 32 bits):

  $ git clone git://github.com/mozilla/gecko-dev
  Cloning into 'gecko-dev'...

  Resolving deltas:  99% (3808820/3811944), completed with 0 local objects.
  fatal: pack has 3124 unresolved deltas
  fatal: index-pack failed

We can fix it by doing direct comparisons between the
offsets and returning constants; the callers only care about
the sign of the comparison, not the magnitude.

4e3687858e config.mak.uname: Darwin: define HAVE_GETDELIM for modern OS X releases
On Mac OS X, getdelim() first became available with Xcode 4.1[1], which
was released the same day as OS X 10.7 "Lion", so assume getdelim()
availability from 10.7 onward. (As of this writing, OS X is at 10.10
"Yosemite".)

According to Wikipedia[2], 4.1 was also available for download by paying
developers on OS X 10.6 "Snow Leopard", so it's possible that some 10.6
machines may have getdelim(). However, as strbuf's use of getdelim() is
purely an optimization, let's be conservative and assume 10.6 and
earlier lack getdelim().

[1]: Or, possibly with Xcode 4.0, but that version is no longer
     available for download, or not available to non-paying developers,
     so testing is not possible.

414382fb00 ewah/bitmap: silence warning about MASK macro redefinition
On PowerPC Mac OS X (10.5.8 "Leopard" with Xcode 3.1),
system header /usr/include/ppc/param.h[1] pollutes the

eb2a8d9ed3 pull: handle git-fetch's options as well
While parsing the command-line arguments, git-pull stops parsing at the
first unrecognized option, assuming that any subsequent options are for
git-fetch, and can thus be kept in the shell's positional parameters
list, so that it can be passed to git-fetch via the expansion of "$@".

However, certain functions in git-pull assume that the positional
parameters do not contain any options:

* error_on_no_merge_candidates() uses the number of positional
  parameters to determine which error message to print out, and will
  thus print the wrong message if git-fetch's options are passed in as
  well.

* the call to get_remote_merge_branch() assumes that the positional
  parameters only contains the optional repo and refspecs, and will
  thus silently fail if git-fetch's options are passed in as well.

* --dry-run is a valid git-fetch option, but if provided after any
  git-fetch options, it is not recognized by git-pull and thus git-pull
  will continue to run the merge or rebase.

Fix these bugs by teaching git-pull to parse git-fetch's options as
well. Add tests to prevent regressions.

This removes the limitation where git-fetch's options have to come after
git-merge's and git-rebase's options on the command line. Update the
documentation to reflect this.

9b7a61d7da format-patch: do not feed tags to clear_commit_marks()
"git format-patch --ignore-if-in-upstream A..B", when either A or B
is a tag, failed miserably.

This is because the code passes the tips it used for traversal to
clear_commit_marks(), after running a temporary revision traversal
to enumerate the commits on both branches to find if they have
commits that make equivalent changes.  The revision traversal
machinery knows how to enumerate commits reachable starting from a
tag, but clear_commit_marks() wants to take nothing but a commit.

In the longer term, it might be a more correct fix to teach
clear_commit_marks() to do the same "committish to commit"
dereferencing that is done in the revision traversal machinery,
but for now this fix should suffice.

revision-walking machinery that we know the history graph
may be incomplete. For example, we use it when walking
unreachable but recent objects; we want to add what we can,
but it's OK if the history is incomplete.

However, we still print error messages for the missing
objects, which can be confusing. This is not an error, but
just a normal situation when transitioning from a repository
last pruned by an older git (which can leave broken segments
of history) to a more recent one (where we try to preserve
whole reachable segments).

We can fix this by adding a new "parse_X_gently" form that
takes a flag to suppress the messages. The existing
"parse_X" form is already gentle in the sense that it
returns an error rather than dying, and we could in theory
just add a "quiet" flag to it (with existing callers passing
"0"). But doing it this way means we do not have to disturb
existing callers.

Note also that the new flag is "quiet_on_missing", and not
just "quiet". We could add a flag to suppress _all_ errors,
but besides being a more invasive change (we would have to
pass the flag down to sub-functions, too), there is a good
reason not to: we would never want to use it. Missing a
linked object is expected in some circumstances, but it is
never expected to have a malformed commit, or to get a tree
when we wanted a commit.  We should always complain about
these corruptions.

fada767463 setup_git_directory: delay core.bare/core.worktree errors
If both core.bare and core.worktree are set, we complain
about the bogus config and die. Dying is good, because it
avoids commands running and doing damage in a potentially
incorrect setup. But dying _there_ is bad, because it means
that commands which do not even care about the work tree
cannot run. This can make repairing the situation harder:

  [setup]
  $ git config core.bare true
  $ git config core.worktree /some/path

  [OK, expected.]
  $ git status
  fatal: core.bare and core.worktree do not make sense

  [Hrm...]
  $ git config --unset core.worktree
  fatal: core.bare and core.worktree do not make sense

  [Nope...]
  $ git config --edit
  fatal: core.bare and core.worktree do not make sense

  [Gaaah.]
  $ git help config
  fatal: core.bare and core.worktree do not make sense

Instead, let's issue a warning about the bogus config when
we notice it (i.e., for all commands), but only die when the
command tries to use the work tree (by calling setup_work_tree).
So we now get:

  $ git status
  warning: core.bare and core.worktree do not make sense
  fatal: unable to set up work tree using invalid config

  $ git config --unset core.worktree
  warning: core.bare and core.worktree do not make sense

We have to update t1510 to accomodate this; it uses
symbolic-ref to check whether the configuration works or
not, but of course that command does not use the working
tree. Instead, we switch it to use `git status`, as it
requires a work-tree, does not need any special setup, and
is read-only (so a failure will not adversely affect further
tests).

In addition, we add a new test that checks the desired
behavior (i.e., that running "git config" with the bogus
config does in fact work).

7c37a5dc82 Makefile: silence perl/PM.stamp recipe
Every time we run "make", we update perl/PM.stamp, which
contains a list of all of the perl module files (if it's
updated, we need to rebuild perl/perl.mak, since the
Makefile will not otherwise know about the new files).

This means that every time "make" is run, we see:

      GEN perl/PM.stamp

in the output, even though it is not likely to have changed.
Let's make this recipe completely silent, as we do for other
auto-generated dependency files (e.g., GIT-CFLAGS).

a2d25ef07f Makefile: avoid timestamp updates to GIT-BUILD-OPTIONS
We force the GIT-BUILD-OPTIONS recipe to run every time
"make" is invoked. We must do this to catch new options
which may have come from the command-line or environment.

However, we actually update the file's timestamp each time
the recipe is run, whether anything changed or not. As a
result, any files which depend on it (for example, all of
the perl scripts, which need to know whether NO_PERL was
set) will be re-built every time.

Let's do our usual trick of writing to a tempfile, then
doing a "cmp || mv" to update the file only when something
changed.
