2014-08-07apply: omit ws check for excluded pathsLibravatar Junio C Hamano1-3/+6
Whitespace breakages are checked while the patch is being parsed. Disable them at the beginning of parse_chunk(), where each individual patch is parsed, immediately after we learn the name of the file the patch applies to and before we start parsing the diff contained in the patch. One may naively think that we should be able to not just skip the whitespace checks but simply fast-forward to the next patch without doing anything once use_patch() tells us that this patch is not going to be used. But in reality we cannot really skip much of the parsing in order to do such a "fast-forward", primarily because parsing "@@ -k,l +m,n @@" lines and counting the input lines is how we determine the boundaries of individual patches.

2014-08-07apply: use the right attribute for paths in non-Git patchesLibravatar Junio C Hamano1-22/+19
We parse each patchfile and find the name of the path the patch applies to, and then use that name to consult the attribute system to find the whitespace rules to be used, and also the target file (either in the working tree or in the index) to replay the changes against. Unlike a Git-generated patch, a non-Git patch is taken to have the pathnames relative to the current working directory. The names found in such a patch are modified by prepending the prefix by the prefix_patches() helper function introduced in 56185f49 (git-apply: require -p<n> when working in a subdirectory., 2007-02-19). However, this prefixing is done after the patch is fully parsed and affects only what target files are patched. Because the attributes are checked against the names found in the patch during the parsing, not against the final pathname, the whitespace check that is done during parsing ends up using attributes for a wrong path for non-Git patches. Fix this by doing the prefix much earlier, immediately after the header part of each patch is parsed and we learn the name of the path the patch affects.

2014-07-24apply: avoid possible bogus pointerLibravatar Jeff King1-1/+1
When parsing "index" lines from a git-diff, we look for a space followed by the mode. If we don't have a space, then we set our pointer to the end-of-line. However, we don't double-check that our end-of-line pointer is valid (e.g., if we got a truncated diff input), which could lead to some wrap-around pointer arithmetic. In most cases this would probably get caught by our "40 < len" check later in the function, but to be on the safe side, let's just use strchrnul to treat end-of-string the same as end-of-line.

Use xmemdupz() to allocate the memory, copy the data and make sure to NUL-terminate the result, all in one step. The resulting code is shorter, doesn't contain the constants 1 and '\0', and avoids duplicating function parameters. For blame, the last copied byte (o->file.ptr[o->file.size]) is always set to NUL by fake_working_tree_commit() or read_sha1_file(), so no information is lost by the conversion to using xmemdupz().

2014-06-20apply: use skip_prefix instead of raw additionLibravatar Jeff King1-2/+3
A submodule diff generally has content like: -Subproject commit [0-9a-f]{40} +Subproject commit [0-9a-f]{40} When we are using "git apply --index" with a submodule, we first apply the textual diff, and then parse that result to figure out the new sha1. If the diff has bogus input like: -Subproject commit 1234567890123456789012345678901234567890 +bogus we will parse the "bogus" portion. Our parser assumes that the buffer starts with "Subproject commit", and blindly skips past it using strlen(). This can cause us to read random memory after the buffer. This problem was unlikely to have come up in practice (since it requires a malformed diff), and even when it did, we likely noticed the problem anyway as the next operation was to call get_sha1_hex on the random memory. However, we can easily fix it by using skip_prefix to notice the parsing error. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-03-26apply --ignore-space-change: lines with and without leading whitespaces do ↵Libravatar Junio C Hamano1-5/+7
not match The fuzzy_matchlines() function is used when attempting to resurrect a patch that is whitespace-damaged, or when applying a patch that was produced against an old codebase to the codebase after indentation change. The patch may want to change a line "a_bc" ("_" is used throught this description for a whitespace to make it stand out) in the original into something else, and we may not find "a_bc" in the current source, but there may be "a__bc" (two spaces instead of one the whitespace-damaged patch claims to expect). By ignoring the amount of whitespaces, it forces "git apply" to consider that "a_bc" in the broken patch meant to refer to "a__bc" in reality. However, the implementation special cases a run of whitespaces at the beginning of a line and makes "abc" match "_abc", even though a whitespace in the middle of string never matches a 0-width gap, e.g. "a_bc" does not match "abc". A run of whitespace at the end of one string does not match a 0-width end of line on the other line, either, e.g. "abc_" does not match "abc". Fix this inconsistency by making the code skip leading whitespaces only when both strings begin with a whitespace. This makes the option mean the same as the option of the same name in "diff" and "git diff". Note that I am not sure if anybody sane should use this option in the first place. The fuzzy match logic may be able to find the original line that the patch author may have meant to touch because it does not fully trust what the original lines say (i.e. context lines prefixed by " " and old lines prefixed by "-" does not have to exactly match the contents the patch is applied to). There is no reason for us to trust what the replacement lines (i.e. new lines prefixed by "+") say, either, but with this option enabled, we end up copying these new lines with suspicious whitespace distributions literally into the patched result. But as long as we keep it, we should make it do its insane thing consistently. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-07-09Convert "struct cache_entry *" to "const ..." wherever possibleLibravatar Nguyễn Thái Ngọc Duy1-6/+7
I attempted to make index_state->cache[] a "const struct cache_entry **" to find out how existing entries in index are modified and where. The question I have is what do we do if we really need to keep track of on-disk changes in the index. The result is - diff-lib.c: setting CE_UPTODATE - name-hash.c: setting CE_HASHED - preload-index.c, read-cache.c, unpack-trees.c and builtin/update-index: obvious - entry.c: write_entry() may refresh the checked out entry via fill_stat_cache_info(). This causes "non-const struct cache_entry *" in builtin/apply.c, builtin/checkout-index.c and builtin/checkout.c - builtin/ls-files.c: --with-tree changes stagemask and may set CE_UPDATE Of these, write_entry() and its call sites are probably most interesting because it modifies on-disk info. But this is stat info and can be retrieved via refresh, at least for porcelain commands. Other just uses ce_flags for local purposes. So, keeping track of "dirty" entries is just a matter of setting a flag in index modification functions exposed by read-cache.c. Except unpack-trees, the rest of the code base does not do anything funny behind read-cache's back. The actual patch is less valueable than the summary above. But if anyone wants to re-identify the above sites. Applying this patch, then this: diff --git a/cache.h b/cache.h index 430d021..1692891 100644 --- a/cache.h +++ b/cache.h @@ -267,7 +267,7 @@ static inline unsigned int canon_mode(unsigned int mode) #define cache_entry_size(len) (offsetof(struct cache_entry,name) + (len) + 1) struct index_state { - struct cache_entry **cache; + const struct cache_entry **cache; unsigned int version; unsigned int cache_nr, cache_alloc, cache_changed; struct string_list *resolve_undo; will help quickly identify them without bogus warnings.

2013-03-22apply --whitespace=fix: avoid running over the postimage bufferLibravatar Junio C Hamano1-6/+10
Originally update-pre-post-images could assume that any whitespace fixing will make the result only shorter by unexpanding runs of leading SPs into HTs and removing trailing whitespaces at the end of lines. Updating the post-image we read from the patch to match the actual result can be performed in-place under this assumption. These days, however, we have tab-in-indent (aka Python) rule whose result can be longer than the original, and we do need to allocate a larger buffer than the input and replace the result. Fortunately the support for lengthening rewrite was already added when we began supporting "match while ignoring whitespace differences" mode in 86c91f91794c (git apply: option to ignore whitespace differences, 2009-08-04).

"git am -3" uses this function to build a tree that records how the preimage the patch was created from would have looked like. An abbreviated object name on the index line is ordinarily sufficient for us to figure out the object name the preimage tree would have contained, but a change to a submodule by definition shows an object name of a submodule commit which our repository should not have, and get_sha1_blob() is not an appropriate way to read it (or get_sha1() for that matter). Use get_sha1_hex() and complain if we do not find a full object name there. We could read from the payload part of the patch to learn the full object name of the commit, but the primary user "git rebase" has been fixed to give us a full object name, so this should suffice for now.

The local variable sha1_ptr in the build_fake_ancestor() function used to either point at the null_sha1[] (if the ancestor did not have the path) or at sha1[] (if we read the object name into the local array), but 7a98869 (apply: get rid of --index-info in favor of --build-fake-ancestor, 2007-09-17) made the "missing in the ancestor" case unnecessary, hence sha1_ptr, when used, always points at the local array. Get rid of the unneeded variable, and restructure the if/else cascade a bit to make it easier to read. There should be no behaviour change. Signed-off-by: Junio C Hamano <gitster@pobox.com>
