When git apply is passed something that is not a patch, it does not produce
an error message or exit with a non-zero status if it was not actually
"applying" the patch i.e. --check or --numstat etc were supplied on the
command line.
Fix this by producing an error when apply fails to find any hunks whatsoever
while parsing the patch.
This will cause some of the output formats (--numstat, --diffstat, etc) to
produce an error when they formerly would have reported zero changes and
exited successfully. That seems like the correct behavior though. Failure
to recognize the input as a patch should be an error.
Plus, add a test.

The above is on glibc-based systems. On other systems, rather than

The size of objects we read from the repository and data we try to put
into the repository are represented in "unsigned long", so that on larger
architectures we can handle objects that weigh more than 4GB.
But the interface defined in zlib.h to communicate with inflate/deflate
limits avail_in (how many bytes of input are we calling zlib with) and
avail_out (how many bytes of output from zlib are we ready to accept)
fields effectively to 4GB by defining their type to be uInt.
In many places in our code, we allocate a large buffer (e.g. mmap'ing a
large loose object file) and tell zlib its size by assigning the size to
avail_in field of the stream, but that will truncate the high octets of
the real size. The worst part of this story is that we often pass around
z_stream (the state object used by zlib) to keep track of the number of
used bytes in input/output buffer by inspecting these two fields, which
practically limits our callchain to the same 4GB limit.
Wrap z_stream in another structure git_zstream that can express avail_in
and avail_out in unsigned long. For now, just die() when the caller gives
a size that cannot be given to a single zlib call. In later patches in the
series, we would make git_inflate() and git_deflate() internally loop to
give callers an illusion that our "improved" version of zlib interface can
operate on a buffer larger than 4GB in one go.

Since 0beee4c (git-add--interactive: remove hunk coalescing, 2008-07-02),
"git add--interactive" behaves lazily and passes overlapping hunks to the
underlying "git apply" without coalescing. This was partially corrected
by 7a26e65 (its partial revert, 2009-05-16), but overlapping hunks are
still passed when the patch is edited.
Teach "git apply" the --allow-overlap option that disables a safety
feature that avoids misapplication of patches by not applying patches
to overlapping hunks, and pass this option form "add -p" codepath.
Do not even advertise the option, as this is merely a workaround, and the
correct fix is to make "add -p" correctly coalesce adjacent patch hunks.

When the line number the patch intended to touch does not match
the line in the version being patched, GNU patch reports that

Signed-off-by: Junio C Hamano <gitster@pobox.com>
When looking for a place to apply a hunk, we used to check lines that
match the preimage of it, starting from the line that the patch wants to
apply the hunk at, looking forward and backward with increasing offsets
until we find a match.
Colin Guthrie found an interesting case where this misapplied a patch that
wanted to touch a preimage that consists of
}
}
return 0;
}
which is a rather unfortunately common pattern.
The target version of the file originally had only one such location, but
the hunk immediately before that created another instance of such block of
lines, and find_pos() happily reported that the preimage of the hunk
matched what it wanted to modify.
Oops.
By marking the lines application of earlier hunks touched and preventing
match_fragment() from considering them as a match with preimage of other
hunks, we can reduce such an accident.
I also considered to teach apply_one_fragment() to take the offset we have
found while applying the previous hunk into account when looking for a
match with find_pos(), but dismissed that approach, because it would
sometimes work better but sometimes worse, depending on the difference
between the version the patch was created against and the version the
patch is being applied.
This does _not_ prevent misapplication of patches to a file that has many
similar looking blocks of lines and a preimage cannot identify which one
of them should be applied. For that, we would need to scan beyond the
first match in find_pos(), and issue a warning (or error out). That will
be a separate topic.

Usually when applying a binary diff generated without
--binary, it will be rejected early, as we don't even have
the full sha1 of the pre- and post-images.
However, if the diff is generated with --full-index (but not
--binary), then we will actually try to apply it. If we have
the postimage blob, then we can take a shortcut and never
even look at the binary diff at all (e.g., this can happen
when rebasing changes within a repository).
If we don't have the postimage blob, though, we try to look
at the actual fragments, of which there are none, and get a
segfault. This patch checks explicitly for that case and
complains to the user instead of segfaulting. We need to
keep the check at a low level so that the "shortcut" case
above continues to work.
We also add a test that demonstrates the segfault. While
we're at it, let's also explicitly test the shortcut case.

To discover filenames from the --- and +++ lines in a traditional
unified diff, currently "git apply" scans forward for a whitespace
character on each line and stops there. It can't use the whole line
because "diff -u" likes to include timestamps, like so:
--- foo 2000-07-12 16:56:50.020000414 -0500
+++ bar 2010-07-12 16:56:50.020000414 -0500
The whitespace-seeking heuristic works great, even when the tab
has been converted to spaces by some email + copy-and-paste
related corruption.
Except for one problem: if the filename itself contains whitespace,
the inferred filename will be too short.
When Giuseppe ran into this problem, it was for a file creation
patch (for debian/licenses/LICENSE.global BSD-style Chromium).
So one can't use the list of files present in the index to deduce an
appropriate filename (not to mention that way lies madness; see
v0.99~402, 2005-05-31).
Instead, look for a timestamp and use that if present to mark the end
of the filename. If no timestamp is present, the old heuristic is
used, with one exception: the space character \040 is not considered
terminating whitespace any more unless it is followed by a timestamp.

about the lack of diff index line when a file already present in the

But it still worries too much: for rename patches, it is checking
that both the old and new filename are present in the current

involves creating a file there was none before.

will just show the choices instead. I think bash has some cut-off

"git apply" strips new blank lines at EOF under --whitespace=fix option,
but neigher --whitespace=warn nor --whitespace=error paid any attention to
these errors.
Introduce a new whitespace error class, blank-at-eof, to make the
whitespace error handling more consistent.
The patch adds a new "linenr" field to the struct fragment in order to
record which line the hunk started in the input file, but this is needed
solely for reporting purposes. The detection of this class of whitespace
errors cannot be done while parsing a patch like we do for all the other
classes of whitespace errors. It instead has to wait until we find where
to apply the hunk, but at that point, we do not have an access to the
original line number in the input file anymore, hence the new field.
Depending on your point of view, this may be a bugfix that makes warn and
error in line with fix. Or you could call it a new feature. The line
between them is somewhat fuzzy in this case.
Strictly speaking, triggering more errors than before is a change in
behaviour that is not backward compatible, even though the reason for the
change is because the code was not checking for an error that it should
have. People who do not want added blank lines at EOF to trigger an error
can disable the new error class.

The command tries to strip blank lines at the end of the file added by a
patch. It is done by first detecting if a hunk in patch has additional
blank lines at the end of itself, and if so checking if such a hunk
applies at the end of file. This patch addresses a bug in the logic to
implement the former (the previous one addressed a bug in the latter).
If the original ends with blank lines, often the patch hunk ends like
this:
@@ -l,5 +m,7 @@$
_context$
_context$
-deleted$
+$
+$
+$
_$
_$
where _ stands for SP and $ shows a end-of-line. This example patch adds
three trailing blank lines, but the code fails to notice it, because it
only pays attention to added blank lines at the very end of the hunk. In
this example, the three added blank lines do not appear textually at the
end in the patch, even though you can see that they are indeed added at
the end, if you rearrange the diff like this:
@@ -l,5 +m,7 @@$

There are a few remaining ones, but this fixes the trivial ones. It boils
down to two main issues that sparse complains about:
- warning: Using plain integer as NULL pointer
Sparse doesn't like you using '0' instead of 'NULL'. For various good
reasons, not the least of which is just the visual confusion. A NULL
pointer is not an integer, and that whole "0 works as NULL" is a
historical accident and not very pretty.
A few of these remain: zlib is a total mess, and Z_NULL is just a 0.
I didn't touch those.
- warning: symbol 'xyz' was not declared. Should it be static?
Sparse wants to see declarations for any functions you export. A lack
of a declaration tends to mean that you should either add one, or you
should mark the function 'static' to show that it's in file scope.
A few of these remain: I only did the ones that should obviously just
be made static.
That 'wt_status_submodule_summary' one is debatable. It has a few related
flags (like 'wt_status_use_color') which _are_ declared, and are used by
builtin-commit.c. So maybe we'd like to export it at some point, but it's
not declared now, and not used outside of that file, so 'static' it is in

OPT_FILENAME is intended to be a more robust fix for the same issue.
OPT_FILENAME and its associated enum OPTION_FILENAME are used to
represent filename options within the parse options API.
This option is similar to OPTION_STRING. If --no is prefixed to the
option the filename is unset. If no argument is given and the default
value is set, the filename is set to the default value. The difference
is that the filename is prefixed with the prefix passed to
parse_options() (or parse_options_start()).
Update git-apply, git-commit, git-fmt-merge-msg, and git-tag to use
OPT_FILENAME with their filename options. Also, rename

2008-08-06) only fixed git-commit and git-tag. But, git-apply and
git-fmt-merge-msg didn't get the update and exhibit the same behavior.
Fix them and add tests for "apply --build-fake-ancestor" and
"fmt-merge-msg -F".

This helps to notice when something's going wrong, especially on
systems which lock open files.
I used the following criteria when selecting the code for replacement:
- it was already printing a warning for the unlink failures
- it is in a function which already printing something or is
called from such a function
- it is in a static function, returning void and the function is only
called from a builtin main function (cmd_)
- it is in a function which handles emergency exit (signal handlers)
- it is in a function which is obvously cleaning up the lockfiles

Example correct diff generated by `diff -M -B' might look like this:
diff --git a/file1 b/file2
similarity index 100%
rename from file1
rename to file2
diff --git a/file2 b/file1
similarity index 100%
rename from file2
rename to file1
Information about removing `file2' comes after information about creation
of new `file2' (renamed from `file1'). Existing implementation isn't able to
apply such patch, because it has to know in advance which files will be
removed.
This patch populates fn_table with information about removal of files
before calling check_patch() for each patch to be applied.
