2b6eef943f Make apply --binary a no-op.
Historically we did not allow binary patch applied without an
explicit permission from the user, and this flag was the way to
do so.  This makes the flag a no-op by always allowing binary
patch application.

9befac470b Replace uses of strdup with xstrdup.
Like xmalloc and xrealloc xstrdup dies with a useful message if
the native strdup() implementation returns NULL rather than a
valid pointer.

I just tried to use xstrdup in new code and found it to be missing.
However I expected it to be present as xmalloc and xrealloc are
already commonly used throughout the code.

[jc: removed the part that deals with last_XXX, which I am
 finding more and more dubious these days.]

8938045a4e git-apply --reject: finishing touches.
After a failed "git am" attempt:

	git apply --reject --verbose .dotest/patch

applies hunks that are applicable and leaves *.rej files the
rejected hunks, and it reports what it is doing.  With --index,
files with a rejected hunk do not get their index entries
updated at all, so "git diff" will show the hunks that
successfully got applied.

Without --verbose to remind the user that the patch updated some
other paths cleanly, it is very easy to lose track of the status
of the working tree, so --reject implies --verbose.

builtin-apply.c defines a local variable 'c' which is used only

57dc397cff git-apply --reject
With the new flag "--reject", hunks that do not apply are sent to
the standard output, and the usable hunks are applied.  The command
itself exits with non-zero status when this happens, so that the
user or wrapper can take notice and sort the remaining mess out.

3cd4f5e8eb git-apply --binary: clean up and prepare for --reverse
This cleans up the implementation of "git-apply --binary", and
implements reverse application of binary patches (when git-diff
is converted to emit reversible binary patches).

Earlier, the types of encoding (either deflated literal or
deflated delta) were stored in is_binary field in struct patch,
which meant that we cannot store more than one fragment that
differ in the encoding for a patch.  This moves the information
to a field in struct fragment that is otherwise unused for
binary patches, and makes it possible to hang two (or more, but
two is enough) hunks for a binary patch.

The original "binary patch" output from git-diff is internally
parsed into an "is_binary" patch with one fragment.  Upcoming
reversible binary patch output will have two fragments, the
first one being the forward patch and the second one the reverse
patch.

40aaae88ad Better error message when we are unable to lock the index file
Most of the callers except the one in refs.c use the function to
update the index file.  Among the index writers, everybody
except write-tree dies if they cannot open it for writing.

This gives the function an extra argument, to tell it to die
when it cannot create a new file as the lockfile.

The only caller that does not have to die is write-tree, because
updating the index for the cache-tree part is optional and not
being able to do so does not affect the correctness.  I think we
do not have to be so careful and make the failure into die() the
same way as other callers, but that would be a different patch.

A type-change diff is always split into a patch to delete old,
immediately followed by a patch to create new.  check_patch()
routine noticed that the path to be created already exists in

creation patch and mistakenly thought it to be an error.

eed46644ca apply: split out removal and creation into different phases.
This reworks write_out_result() loop so we first remove the paths that

c28c571c14 apply: check D/F conflicts more carefully.
When creating a new file where a directory used to be (or the user had
an empty directory) the code did not check the result from lstat() closely
enough, and mistakenly thought the path already existed in the working tree.

This does not fix the problem where you have a patch that creates a file
at "foo" and removes a file at "foo/bar" (which presumably is the last file
in "foo/" directory in the original).  For that, we would need to restructure
write_out_results() loop.

This doesn't make the code uglier or harder to read, yet it makes the
code more portable.  This also simplifies checking for other potential
incompatibilities.  "gcc -std=c89 -pedantic" can flag many incompatible
constructs as warnings, but C99 comments will cause it to emit an error.

3eaa38da94 apply: replace NO_ACCURATE_DIFF with --inaccurate-eof runtime flag.
It does not make much sense to build git whose behaviour is
different depending on the brokenness of diff implementation of
the platform because the brokenness of the patch that is applied
with the tool depends on brokenness of the diff the person who
generates the patch uses.  So we do not use NO_ACCURATE_DIFF
anymore, but help people to apply patches that do not record
incomplete lines correctly with a runtime flag.
