2015-04-22ignore: info/exclude should trump core.excludesfileLibravatar Junio C Hamano1-0/+10
$GIT_DIR/info/exclude and core.excludesfile (which falls back to $XDG_HOME/git/ignore) are both ways to override the ignore pattern lists given by the project in .gitignore files. The former, which is per-repository personal preference, should take precedence over the latter, which is a personal preference default across different repositories that are accessed from that machine. The existing documentation also agrees. However, the precedence order was screwed up between these two from the very beginning when 896bdfa2 (add: Support specifying an excludes file with a configuration variable, 2007-02-27) introduced core.excludesfile variable.

2014-12-29is_hfs_dotgit: loosen over-eager match of \u{..47}Libravatar Jeff King1-0/+15
Our is_hfs_dotgit function relies on the hackily-implemented next_hfs_char to give us the next character that an HFS+ filename comparison would look at. It's hacky because it doesn't implement the full case-folding table of HFS+; it gives us just enough to see if the path matches ".git". At the end of next_hfs_char, we use tolower() to convert our 32-bit code point to lowercase. Our tolower() implementation only takes an 8-bit char, though; it throws away the upper 24 bits. This means we can't have any false negatives for is_hfs_dotgit. We only care about matching 7-bit ASCII characters in ".git", and we will correctly process 'G' or 'g'. However, we _can_ have false positives. Because we throw away the upper bits, code point \u{0147} (for example) will look like 'G' and get downcased to 'g'. It's not known whether a sequence of code points whose truncation ends up as ".git" is meaningful in any language, but it does not hurt to be more accurate here. We can just pass out the full 32-bit code point, and compare it manually to the upper and lowercase characters we care about.

2014-12-17fsck: complain about NTFS ".git" aliases in treesLibravatar Johannes Schindelin1-2/+7
Now that the index can block pathnames that can be mistaken to mean ".git" on NTFS and FAT32, it would be helpful for fsck to notice such problematic paths. This lets servers which use receive.fsckObjects block them before the damage spreads. Note that the fsck check is always on, even for systems without core.protectNTFS set. This is technically more restrictive than we need to be, as a set of users on ext4 could happily use these odd filenames without caring about NTFS. However, on balance, it's helpful for all servers to block these (because the paths can be used for mischief, and servers which bother to fsck would want to stop the spread whether they are on NTFS themselves or not), and hardly anybody will be affected (because the blocked names are variants of .git or git~1, meaning mischief is almost certainly what the tree author had in mind). Ideally these would be controlled by a separate "fsck.protectNTFS" flag. However, it would be much nicer to be able to enable/disable _any_ fsck flag individually, and any scheme we choose should match such a system. Given the likelihood of anybody using such a path in practice, it is not unreasonable to wait until such a system materializes.

2014-12-17read-cache: optionally disallow NTFS .git variantsLibravatar Johannes Schindelin1-0/+13
The point of disallowing ".git" in the index is that we would never want to accidentally overwrite files in the repository directory. But this means we need to respect the filesystem's idea of when two paths are equal. The prior commit added a helper to make such a comparison for NTFS and FAT32; let's use it in verify_path(). We make this check optional for two reasons: 1. It restricts the set of allowable filenames, which is unnecessary for people who are not on NTFS nor FAT32. In practice this probably doesn't matter, though, as the restricted names are rather obscure and almost certainly would never come up in practice. 2. It has a minor performance penalty for every path we insert into the index. This patch ties the check to the core.protectNTFS config option. Though this is expected to be most useful on Windows, we allow it to be set everywhere, as NTFS may be mounted on other platforms. The variable does default to on for Windows, though.

We check that fsck notices and complains about confusing paths in trees. However, there are a few shortcomings: 1. We check only for these paths as file entries, not as intermediate paths (so ".git" and not ".git/foo"). 2.

2014-01-15revision: propagate flag bits from tags to pointeesLibravatar Junio C Hamano1-0/+11
With the previous fix 895c5ba3 (revision: do not peel tags used in range notation, 2013-09-19), handle_revision_arg() that processes command line arguments for the "git log" family of commands no longer directly places the object pointed by the tag in the pending object array when it sees a tag object. We used to place pointee there after copying the flag bits like UNINTERESTING and SYMMETRIC_LEFT. This change meant that any flag that is relevant to later history traversal must now be propagated to the pointed objects (most often these are commits) while starting the traversal, which is partly done by handle_commit() that is called from prepare_revision_walk(). We did propagate UNINTERESTING, but did not do so for others, most notably SYMMETRIC_LEFT. This caused "git log --left-right v1.0..." (where "v1.0" is a tag) to start losing the "leftness" from the commit the tag points at. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-01-15revision: mark contents of an uninteresting tree uninterestingLibravatar Junio C Hamano1-0/+6
"git rev-list --objects ^A^{tree} B^{tree}" ought to mean "I want a list of objects inside B's tree, but please exclude the objects that appear inside A's tree". we see the top-level tree marked as uninteresting (i.e. ^A^{tree} in the above example) and call mark_tree_uninteresting() on it; this unfortunately prevents us from recursing into the tree and marking the objects in the tree as uninteresting. The reason why "git log ^A A" yields an empty set of commits, i.e. we do not have a similar issue for commits, is because we call mark_parents_uninteresting() after seeing an uninteresting commit. The uninteresting-ness of the commit itself does not prevent its parents from being marked as uninteresting. Introduce mark_tree_contents_uninteresting() and structure the code in handle_commit() in such a way that it makes it the responsibility of the callchain leading to this function to mark commits, trees and blobs as uninteresting, and also make it the responsibility of the helpers called from this function to mark objects that are reachable from them. Note that this is a very old bug that probably dates back to the day when "rev-list --objects" was introduced. The line to clear tree->object.parsed at the end of mark_tree_contents_uninteresting() can be removed when this fix is merged to the codebase after 6e454b9a (clear parsed flag when we free tree buffers, 2013-06-05).

2014-01-15interpret_branch_name: find all possible @-marksLibravatar Jeff King1-0/+21
When we parse a string like "foo@{upstream}", we look for the first "@"-sign, and check to see if it is an upstream mark. However, since branch names can contain an @, we may also see "@foo@{upstream}". In this case, we check only the first @, and ignore the second. As a result, we do not find the upstream. We can solve this by iterating through all @-marks in the string, and seeing if any is a legitimate upstream or empty-at mark. Another strategy would be to parse from the right-hand side of the string. However, that does not work for the "empty_at" case, which allows "@@{upstream}". We need to find the left-most one in this case (and we then recurse as "HEAD@{upstream}"). Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-01-15interpret_branch_name: avoid @{upstream} past colonLibravatar Jeff King1-0/+16
get_sha1() cannot currently parse a valid object name like "HEAD:@{upstream}" (assuming that such an oddly named file exists in the HEAD commit). It takes two passes to parse the string: 1. It first considers the whole thing as a ref, which results in looking for the upstream of "HEAD:". 2. It finds the colon, parses "HEAD" as a tree-ish, and then finds the path "@{upstream}" in the tree. For a path that looks like a normal reflog (e.g., "HEAD:@{yesterday}"), the first pass is a no-op. We try to dwim_ref("HEAD:"), that returns zero refs, and we proceed with colon-parsing. For "HEAD:@{upstream}", though, the first pass ends up in interpret_upstream_mark, which tries to find the branch "HEAD:". When it sees that the branch does not exist, it actually dies rather than returning an error to the caller. As a result, we never make it to the second pass. One obvious way of fixing this would be to teach interpret_upstream_mark to simply report "no, this isn't an upstream" in such a case. However, that would make the error-reporting for legitimate upstream cases significantly worse. Something like "bogus@{upstream}" would simply report "unknown revision: bogus@{upstream}", while the current code diagnoses a wide variety of possible misconfigurations (no such branch, branch exists but does not have upstream, etc). However, we can take advantage of the fact that a branch name cannot contain a colon. Therefore even if we find an upstream mark, any prefix with a colon must mean that the upstream mark we found is actually a pathname, and should be disregarded completely. This patch implements that logic. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-01-15interpret_branch_name: always respect "namelen" parameterLibravatar Jeff King1-1/+14
interpret_branch_name gets passed a "name" buffer to parse, along with a "namelen" parameter representing its length. If "namelen" is zero, we fallback to the NUL-terminated string-length of "name". However, it does not necessarily follow that if we have gotten a non-zero "namelen", it is the NUL-terminated string-length of "name". E.g., when get_sha1() is parsing "foo:bar", we will be asked to operate only on the first three characters. Yet in interpret_branch_name and its helpers, we use string functions like strchr() to operate on "name", looking past the length we were given. This can result in us mis-parsing object names. We should instead be limiting our search to "namelen" bytes. There are three distinct types of object names this patch addresses: - The intrepret_empty_at helper uses strchr to find the next @-expression after our potential empty-at. In an expression like "@:foo@bar", it erroneously thinks that the second "@" is relevant, even if we were asked only to look at the first character. This case is easy to trigger (and we test it in this patch). - When finding the initial @-mark for @{upstream}, we use strchr. This means we might treat "foo:@{upstream}" as the upstream for "foo:", even though we were asked only to look at "foo". We cannot test this one in practice, because it is masked by another bug (which is fixed in the next patch). - The interpret_nth_prior_checkout helper did not receive the name length at all. This turns out not to be a problem in practice, though, because its parsing is so limited: it always starts from the far-left of the string, and will not tolerate a colon (which is currently the only way to get a smaller-than-strlen "namelen"). However, it's still worth fixing to make the code more obviously correct, and to future-proof us against callers with more exotic buffers.

2014-01-15fetch-pack: do not filter out one-level refsLibravatar Jeff King1-0/+11
Currently fetching a one-level ref like "refs/foo" does not work consistently. The outer "git fetch" program filters the list of refs, checking each against check_refname_format. Then it feeds the result to do_fetch_pack to actually negotiate the haves/wants and get the pack. The fetch-pack code does its own filter, and it behaves differently. The fetch-pack filter looks for refs in "refs/", and then feeds everything _after_ the slash (i.e., just "foo") into check_refname_format. But check_refname_format is not designed to look at a partial refname. It complains that the ref has only one component, thinking it is at the root (i.e., alongside "HEAD"), when in reality we just fed it a partial refname. As a result, we omit a ref like "refs/foo" from the pack request, even though "git fetch" then tries to store the resulting ref. If we happen to get the object anyway (e.g., because the ref is contained in another ref we are fetching), then the fetch succeeds. But if it is a unique object, we fail when trying to update "refs/foo". We can fix this by just passing the whole refname into check_refname_format; we know the part we were omitting is "refs/", which is acceptable in a refname. This at least makes the checks consistent with each other. This problem happens most commonly with "refs/stash", which is the only one-level ref in wide use. However, our test does not use "refs/stash", as we may later want to restrict it specifically (not because it is one-level, but because of the semantics of stashes). We may also want to do away with the multiple levels of filtering (which can cause problems when they are out of sync), or even forbid one-level refs entirely. However, those decisions can come later; this fixes the most immediate problem, which is the mismatch between the two.

2013-12-27Remove the line length limit for graft filesLibravatar Johannes Schindelin2-1/+36
Support for grafts predates Git's strbuf, and hence it is understandable that there was a hard-coded line length limit of 1023 characters (which was chosen a bit awkwardly, given that it is *exactly* one byte short of aligning with the 41 bytes occupied by a commit name and the following space or new-line character). While regular commit histories hardly win comprehensibility in general if they merge more than twenty-two branches in one go, it is not Git's business to limit grafts in such a way. In this particular developer's case, the use case that requires substantially longer graft lines to be supported is the visualization of the commits' order implied by their changes: commits are considered to have an implicit relationship iff exchanging them in an interactive rebase would result in merge conflicts. Thusly implied branches tend to be very shallow in general, and the resulting thicket of implied branches is usually very wide; It is actually quite common that *most* of the commits in a topic branch have not even one implied parent, so that a final merge commit has about as many implied parents as there are commits in said branch.

This behavior was added in 07d7bed (add: don't complain when adding empty project root - 2009-04-28) then broken by 84b8b5d (remove match_pathspec() in favor of match_pathspec_depth() - 2013-07-14).

2013-12-20log: properly handle decorations with chained tagsLibravatar brian m. carlson1-0/+15
git log did not correctly handle decorations when a tag object referenced another tag object that was no longer a ref, such as when the second tag was deleted. The commit would not be decorated correctly because parse_object had not been called on the second tag and therefore its tagged field had not been filled in, resulting in none of the tags being associated with the relevant commit. Call parse_object to fill in this field if it is absent so that the chain of tags can be dereferenced and the commit can be properly decorated. Include tests as well to prevent future regressions.

2013-12-12cat-file: handle --batch format with missing type/sizeLibravatar Jeff King1-0/+22
Commit 98e2092 taught cat-file to stream blobs with --batch, which requires that we look up the object type before loading it into memory. As a result, we now print the object header from information in sha1_object_info, and the actual contents from the read_sha1_file. We double-check that the information we printed in the header matches the content we are about to show. Later, commit 93d2a60 allowed custom header lines for --batch, and commit 5b08640 made type lookups optional. As a result, specifying a header line without the type or size means that we will not look up those items at all. This causes our double-checking to erroneously die with an error; we think the type or size has changed, when in fact it was simply left at "0". For the size, we can fix this by only doing the consistency double-check when we have retrieved the size via sha1_object_info. In the case that we have not retrieved the value, that means we also did not print it, so there is nothing for us to check that we are consistent with. We could do the same for the type. However, besides our consistency check, we also care about the type in deciding whether to stream or not. So instead of handling the case where we do not know the type, this patch instead makes sure that we always trigger a type lookup when we are printing, so that even a format without the type will stream as we would in the normal case.

2013-12-09connect.c: refactor url parsingLibravatar Torsten Bögershausen2-0/+15
Make the function is_local() in transport.c public, rename it into url_is_local_not_ssh() and use it in both transport.c and connect.c Use a protocol "local" for URLs for the local file system. One note about using file:// under Windows: The (absolute) path on Unix like system typically starts with "/". When the host is empty, it can be omitted, so that a shell scriptlet url=file://$pwd will give a URL like "file:///home/user/repo". Windows does not have the same concept of a root directory located in "/". When parsing the URL allow "file://C:/user/repo" (even if RFC1738 indicates that "file:///C:/user/repo" should be used).

2013-12-09git fetch: support host:/~repoLibravatar Torsten Bögershausen2-10/+26
The documentation (in urls.txt) says that "ssh://host:/~repo", "host:/~repo" or "host:~repo" specify the repository "repo" in the home directory at "host". This has not been working for "host:/~repo". Before commit 356bec "Support [address] in URLs", the comparison "url != hostname" could be used to determine if the URL had a scheme or not: "ssh://host/host" != "host". However, after 356bec "[::1]" was converted into "::1", yielding url != hostname as well. To fix this regression, don't use "if (url != hostname)", but look at the separator instead. Rename the variable "c" into "separator" to make it easier to read. Signed-off-by: Torsten Bögershausen <tboegi@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-12-09rev-parse: correctly diagnose revision errors before "--"Libravatar Jeff King1-0/+24
Rev-parse understands that a "--" may separate revisions and filenames, and that anything after the "--" is taken as-is. However, it does not understand that anything before the token must be a revision (which is the usual rule implemented by the setup_revisions parser). Since rev-parse prefers revisions to files when parsing before the "--", we end up with the correct result (if such an argument is a revision, we parse it as one, and if it is not, it is an error either way). However, we misdiagnose the errors: $ git rev-parse foobar -- >/dev/null fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]' $ >foobar $ git rev-parse foobar -- >/dev/null fatal: bad flag '--' used after filename In both cases, we should know that the real error is that "foobar" is meant to be a revision, but could not be resolved.

2013-12-05commit -v: strip diffs and submodule shortlogs from the commit messageLibravatar Jens Lehmann1-1/+27
When using the '-v' option of "git commit" the diff added to the commit message temporarily for editing is stripped off after the user exited the editor by searching for "\ndiff --git " and truncating the commmit message there if it is found. But this approach has two problems: - when the commit message itself contains a line starting with "diff --git" it will be truncated there prematurely; and - when the "diff.submodule" setting is set to "log", the diff may start with "Submodule <hash1>..<hash2>", which will be left in the commit message while it shouldn't. Fix that by introducing a special scissor separator line starting with the comment character ('#' or the core.commentChar config if set) followed by two lines describing what it is for. The scissor line - which will not be translated - is used to reliably detect the start of the diff so it can be chopped off from the commit message, no matter what the user enters there. Turn a known test failure fixed by this change into a successful test; also add one for a diff starting with a submodule log and another one for proper handling of the comment char.
