| * builtin/apply.c: report error on failure to recognize inputBrandon Casey2011-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed this when "git am CORRUPTED" unexpectedly failed with an odd diagnostic, and even removed one of the files it was supposed to have patched. Reproduce with any valid old/new patch from which you have removed the "+++ b/FILE" line. You'll see a diagnostic like this fatal: unable to write file '(null)' mode 100644: Bad address and you'll find that FILE has been removed. The above is on glibc-based systems. On other systems, rather than getting "null", you may provoke a segfault as git tries to dereference the NULL file name.

* | zlib: zlib can only process 4GB at a timeJunio C Hamano2011-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | apply: do not patch lines that were already patchedJunio C Hamano2011-03-04
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some patches have a timezone formatted like '-08:00' instead of '-0800' in their ---/+++ lines (e.g. http://lwn.net/Articles/131729/). Take this into account when searching for the start of the timezone (which is the end of the filename). This does not actually affect the outcome of patching unless (1) a file being patched has a non-' ' whitespace character (e.g., tab) in its filename, or (2) the patch is whitespace-damaged, so the tab between filename and timestamp has been replaced with spaces.

* | apply: don't segfault on binary files with missing dataJeff King2010-10-29
|/ | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

|/ | | | | | | | | | | | | | | | | | | | | | With v1.5.3.2~14 (apply --index-info: fall back to current index for mode changes, 2007-09-17), git apply learned to stop worrying about the lack of diff index line when a file already present in the current index had no content change. But it still worries too much: for rename patches, it is checking that both the old and new filename are present in the current index. This makes no sense, since a file rename generally involves creating a file there was none before. So just check the old filename. Noticed while trying to use “git rebase” with diff.renames = copies.

(y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
