2013-04-17cat-file: print tags raw for "cat-file -p"Libravatar Jeff King1-4/+1
When "cat-file -p" prints commits, it shows them in their raw format, since git's format is already human-readable. For tags, however, we print the whole thing raw except for one thing: we convert the timestamp on the tagger line into a human-readable date. This dates all the way back to a0f15fa (Pretty-print tagger dates, 2006-03-01). At that time there was no other way to pretty-print a tag. These days, however, neither of those matters much. The normal way to pretty-print a tag is with "git show", which is much more flexible than "cat-file -p". Commit a0f15fa also built "verify-tag --verbose" (and subsequently "tag -v") around the "cat-file -p" output. However, that behavior was lost in commit 62e09ce (Make git tag a builtin, 2007-07-20), and we went back to printing the raw tag contents. Nobody seems to have noticed the bug since then (and it is arguably a saner behavior anyway, as it shows the actual bytes for which we verified the signature). Let's drop the tagger-date formatting for "cat-file -p". It makes us more consistent with cat-file's commit pretty-printer, and as a bonus, we can drop the hand-rolled tag parsing code in cat-file (which happened to behave inconsistently with the tag pretty-printing code elsewhere). This is a change of output format, so it's possible that some callers could considered this a regression. However, the original behavior was arguably a bug (due to the inconsistency with commits), likely nobody was relying on it (even we do not use it ourselves these days), and anyone relying on the "-p" pretty-printer should be able to expect a change in the output format (i.e., while "cat-file" is plumbing, the output format of "-p" was never guaranteed to be stable).

2013-03-28t: check that a pattern without trailing slash matches a directoryLibravatar Jeff King1-0/+27
Prior to v1.8.1.1, with: git init echo content >foo && mkdir subdir && echo content >subdir/bar && echo "subdir export-ignore" >.gitattributes git add . && git commit -m one && git archive HEAD | tar tf - the resulting archive would contain only "foo" and ".gitattributes", not subdir. This was broken with a recent change that intended to allow "subdir/ export-ignore" to also exclude the directory, but instead ended up _requiring_ the trailing slash by mistake. A pattern "subdir" should match any path "subdir", whether it is a directory or a non-directory. A pattern "subdir/" insists that a path "subdir" must be a directory for it to match. This patch adds test not just for this simple case, but also for deeper cross-directory cases, as well as cases with wildcards.

2013-03-22Fix revision walk for commits with the same datesLibravatar Kacper Kornet1-0/+13
Logic in still_interesting function allows to stop the commits traversing if the oldest processed commit is not older then the youngest commit on the list to process and the list contains only commits marked as not interesting ones. It can be premature when dealing with a set of coequal commits. For example git rev-list A^! --not B provides wrong answer if all commits in the range A..B had the same commit time and there are more then 7 of them.

2013-03-18pack-refs: add fully-peeled traitLibravatar Michael Haggerty1-0/+22
Older versions of pack-refs did not write peel lines for refs outside of refs/tags. This meant that on reading the pack-refs file, we might set the REF_KNOWS_PEELED flag for such a ref, even though we do not know anything about its peeled value. The previous commit updated the writer to always peel, no matter what the ref is. That means that packed-refs files written by newer versions of git are fine to be read by both old and new versions of git. However, we still have the problem of reading packed-refs files written by older versions of git, or by other implementations which have not yet learned the same trick. The simplest fix would be to always unset the REF_KNOWS_PEELED flag for refs outside of refs/tags that do not have a peel line (if it has a peel line, we know it is valid, but we cannot assume a missing peel line means anything). But that loses an important optimization, as upload-pack should not need to load the object pointed to by refs/heads/foo to determine that it is not a tag. Instead, we add a "fully-peeled" trait to the packed-refs file. If it is set, we know that we can trust a missing peel line to mean that a ref cannot be peeled. Otherwise, we fall back to assuming nothing.

2013-03-17pack-refs: write peeled entry for non-tagsLibravatar Jeff King1-0/+42
When we pack an annotated tag ref, we write not only the sha1 of the tag object along with the ref, but also the sha1 obtained by peeling the tag. This lets readers of the pack-refs file know the peeled value without having to actually load the object, speeding up upload-pack's ref advertisement. The writer marks a packed-refs file with peeled refs using the "peeled" trait at the top of the file. When the reader sees this trait, it knows that each ref is either followed by its peeled value, or it is not an annotated tag. However, there is a mismatch between the assumptions of the reader and writer. The writer will only peel refs under refs/tags, but the reader does not know this; it will assume a ref without a peeled value must not be a tag object. Thus an annotated tag object placed outside of the refs/tags hierarchy will not have its peeled value printed by upload-pack. The simplest way to fix this is to start writing peel values for all refs. This matches what the reader expects for both new and old versions of git.

2013-03-16upload-pack: make sure "want" objects are parsedLibravatar Jeff King1-0/+9
When upload-pack receives a "want" line from the client, it adds it to an object array. We call lookup_object to find the actual object, which will only check for objects already in memory. This works because we are expecting to find objects that we already loaded during the ref advertisement. We use the resulting object structs for a variety of purposes. Some of them care only about the object flags, but others care about the type of the object (e.g., ok_to_give_up), or even feed them to the revision parser (when --depth is used), which assumes that objects it receives are fully parsed. Once upon a time, this was OK; any object we loaded into memory would also have been parsed. But since 435c833 (upload-pack: use peel_ref for ref advertisements, 2012-10-04), we try to avoid parsing objects during the ref advertisement. This means that lookup_object may return an object with a type of OBJ_NONE. The resulting mess depends on the exact set of objects, but can include the revision parser barfing, or the shallow code sending the wrong set of objects. This patch teaches upload-pack to parse each "want" object as we receive it. We do not replace the lookup_object call with parse_object, as the current code is careful not to let just any object appear on a "want" line, but rather only one we have previously advertised (whereas parse_object would actually load any arbitrary object from disk).

2013-03-14entry: fix filter lookupLibravatar John Keeping1-0/+26
When looking up the stream filter, write_entry() should be passing the path of the file in the repository, not the path to which the content is going to be written. This allows the file to be correctly looked up against the .gitattributes files in the working tree. This change makes the streaming case match the non-streaming case which passes ce->name to convert_to_working_tree later in the same function. The two tests added here test the different paths through write_entry since the CRLF filter is a streaming filter but the user-defined smudge filter is not streamed.

2013-03-10archive: handle commits with an empty treeLibravatar Jeff King2-0/+102
git-archive relies on get_pathspec to convert its argv into a list of pathspecs. When get_pathspec is given an empty argv list, it returns a single pathspec, the empty string, to indicate that everything matches. When we feed this to our path_exists function, we typically see that the pathspec turns up at least one item in the tree, and we are happy. But when our tree is empty, we erroneously think it is because the pathspec is too limited, when in fact it is simply that there is nothing to be found in the tree. This is a weird corner case, but the correct behavior is almost certainly to produce an empty archive, not to exit with an error. This patch teaches git-archive to create empty archives when there is no pathspec given (we continue to complain if a pathspec is given, since it obviously is not matched). It also confirms that the tar and zip writers produce sane output in this instance. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-03-09format-patch: RFC 2047 says multi-octet character may not be splitLibravatar Kirill Smelkov1-13/+14
Even though an earlier attempt (bafc478..41dd00bad) cleaned up RFC 2047 encoding, pretty.c::add_rfc2047() still decides where to split the output line by going through the input one byte at a time, and potentially splits a character in the middle. A subject line may end up showing like this: ".... fö?? bar". (instead of ".... föö bar".) if split incorrectly. RFC 2047, section 5 (3) explicitly forbids such beaviour Each 'encoded-word' MUST represent an integral number of characters. A multi-octet character may not be split across adjacent 'encoded- word's. that means that e.g. for Subject: .... föö bar encoding Subject: =?UTF-8?q?....=20f=C3=B6=C3=B6?= =?UTF-8?q?=20bar?= is correct, and Subject: =?UTF-8?q?....=20f=C3=B6=C3?= <-- NOTE ö is broken here =?UTF-8?q?=B6=20bar?= is not, because "ö" character UTF-8 encoding C3 B6 is split here across adjacent encoded words. To fix the problem, make the loop grab one _character_ at a time and determine its output length to see where to break the output line. Note that this version only knows about UTF-8, but the logic to grab one character is abstracted out in mbs_chrlen() function to make it possible to extend it to other encodings with the help of iconv in the future.

2013-03-08setup: suppress implicit "." work-tree for bare reposLibravatar Jeff King1-0/+19
If an explicit GIT_DIR is given without a working tree, we implicitly assume that the current working directory should be used as the working tree. E.g.,: GIT_DIR=/some/repo.git git status would compare against the cwd. Unfortunately, we fool this rule for sub-invocations of git by setting GIT_DIR internally ourselves. For example: git init foo cd foo/.git git status ;# fails, as we expect git config alias.st status git status ;# does not fail, but should What happens is that we run setup_git_directory when doing alias lookup (since we need to see the config), set GIT_DIR as a result, and then leave GIT_WORK_TREE blank (because we do not have one). Then when we actually run the status command, we do setup_git_directory again, which sees our explicit GIT_DIR and uses the cwd as an implicit worktree. It's tempting to argue that we should be suppressing that second invocation of setup_git_directory, as it could use the values we already found in memory. However, the problem still exists for sub-processes (e.g., if "git status" were an external command). You can see another example with the "--bare" option, which sets GIT_DIR explicitly. For example: git init foo cd foo/.git git status ;# fails git --bare status ;# does NOT fail We need some way of telling sub-processes "even though GIT_DIR is set, do not use cwd as an implicit working tree". We could do it by putting a special token into GIT_WORK_TREE, but the obvious choice (an empty string) has some portability problems. Instead, we add a new boolean variable, GIT_IMPLICIT_WORK_TREE, which suppresses the use of cwd as a working tree when GIT_DIR is set. We trigger the new variable when we know we are in a bare setting. The variable is left intentionally undocumented, as this is an internal detail (for now, anyway). If somebody comes up with a good alternate use for it, and once we are confident we have shaken any bugs out of it, we can consider promoting it further.
