2017-07-09branch: set remote color in ref-filter branch immediatelyLibravatar Jeff King1-5/+6
We set the current and local branch colors at the top of the build_format() function. Let's do the same for the remote color. This saves a little bit of repetition, but more importantly it puts all of the color-setting in the same place. That makes it easier to see that we are coloring all possibilities.

2017-07-09branch: use BRANCH_COLOR_LOCAL in ref-filter formatLibravatar Jeff King1-2/+3
Since 949af0684 (branch: use ref-filter printing APIs, 2017-01-10), git-branch's output is generated by passing a custom format to the ref-filter code. This format forgot to pass BRANCH_COLOR_LOCAL, meaning that local branches (besides the current one) were never colored at all. We can add it in the %(if) block where we decide whether the branch is "current" or merely "local". Note that this means the current/local coloring is either/or. You can't set: [color "branch"] local = blue current = bold and expect the current branch to be "bold blue". This matches the pre-949af0684 behavior.

2017-07-09branch: only perform HEAD check for local branchesLibravatar Jeff King1-1/+2
When assembling the ref-filter format to show "git branch" output, we put the "%(if)%(HEAD)" conditional at the start of the overall format. But there's no point in checking whether a remote branch matches HEAD, as it never will. The check should go inside the local conditional; we assemble that format inside the "local" strbuf. By itself, this is just a minor optimization. But in a future patch, we'll need this refactoring to fix local-branch coloring.

The helper function utf8_fprintf(fp, ...) has exactly the same effect to the output stream fp as fprintf(fp, ...) does, and the only difference is that its return value counts in display columns consumed (assuming that the payload is encoded in UTF-8), as opposed to number of bytes.

2017-06-01pull: ff --rebase --autostash works in dirty repoLibravatar Tyler Brazier1-11/+14
When `git pull --rebase --autostash` in a dirty repository resulted in a fast-forward, nothing was being autostashed and the pull failed. This was due to a shortcut to avoid running rebase when we can fast-forward, but autostash is ignored on that codepath. Now we will only take the shortcut if autostash is not in effect. Based on a few tests against the git.git repo, the shortcut does not seem to give us significant performance benefits, on Linux at least.

2017-05-31C style: use standard style for "TRANSLATORS" commentsLibravatar Ævar Arnfjörð Bjarmason3-10/+18
Change all the "TRANSLATORS: [...]" comments in the C code to use the regular Git coding style, and amend the style guide so that the example there uses that style. This custom style was necessary back in 2010 when the gettext support was initially added, and was subsequently documented in commit cbcfd4e3ea ("i18n: mention "TRANSLATORS:" marker in Documentation/CodingGuidelines", 2014-04-18). GNU xgettext hasn't had the parsing limitation that necessitated this exception for almost 3 years. Since its 0.19 release on 2014-06-02 it's been able to recognize TRANSLATOR comments in the standard Git comment syntax[1]. Usually we'd like to keep compatibility with software that's that young, but in this case literally the only person who needs to be using a gettext newer than 3 years old is Jiang Xin (the only person who runs & commits "make pot" results), so I think in this case we can make an exception. This xgettext parsing feature was added after a thread on the Git mailing list[2] which continued on the bug-gettext[3] list, but we never subsequently changed our style & styleguide, do so. There are already longstanding changes in git that use the standard comment style & have their TRANSLATORS comments extracted properly without getting the literal "*"'s mixed up in the text, as would happen before xgettext 0.19. Commit 7ff2683253 ("builtin-am: implement -i/--interactive", 2015-08-04) added one such comment, which in commit df0617bfa7 ("l10n: git.pot: v2.6.0 round 1 (123 new, 41 removed)", 2015-09-05) got picked up in the po/git.pot file with the right format, showing that Jiang already runs a modern xgettext. The xgettext parser does not handle the sort of non-standard comment style that I'm amending here in sequencer.c, but that isn't standard Git comment syntax anyway. With this change to sequencer.c & "make pot" the comment in the pot file is now correct: #. TRANSLATORS: %s will be "revert", "cherry-pick" or -#. * "rebase -i". +#.

2017-05-30am: handle "-h" argument earlierLibravatar Jeff King1-0/+3
If the user provides "-h" on the command line, then our parse_options() invocation will show a usage message and quit. But if "-h" is the only argument, the git wrapper behaves specially: it ignores our RUN_SETUP flag and calls cmd_am() without having done repository setup at all. This is due to 99caeed05 (Let 'git <command> -h' show usage without a git dir, 2009-11-09). Before cmd_am() calls parse_options(), though, it runs a few other setup functions. One of these is am_state_init(), which uses git_pathdup() to set up the default rebase-apply path. But calling git_pathdup() when we haven't done repository setup will fall back to using ".git". That's mostly harmless (since we won't use the value anyway), but is forbidden since b1ef400eec ("setup_git_env: avoid blind fall-back to ".git"", 2016-10-20), and we now BUG(). We can't easily move that setup to after the parse_options() call; the point is to set up defaults that are overwritten by the option parsing. Instead, we'll detect the "-h" case early and show the usage then. This matches the behavior of other builtins which have a similar setup-ordering issue (e.g., git-branch).

2017-05-24diff: use blob path for blob/file diffsLibravatar Jeff King1-1/+2
When we diff a blob against a working tree file like: git diff HEAD:Makefile Makefile we always use the working tree filename for both sides of the diff. In most cases that's fine, as the two would be the same anyway, as above. And until recently, we used the "name" for the blob, not the path, which would have the messy "HEAD:" on the beginning. But when they don't match, like: git diff HEAD:old_path new_path it makes sense to show both names. This patch uses the blob's path field if it's available, and otherwise falls back to using the filename (in preference to the blob's name, which is likely to be garbage like a raw sha1).

2017-05-24diff: use pending "path" if it is availableLibravatar Jeff King1-1/+6
There's a subtle distinction between "name" and "path" for a blob that we resolve: the name is what the user told us on the command line, and the path is what we traversed when finding the blob within a tree (if we did so). When we diff blobs directly, we use "name", but "path" is more likely to be useful to the user (it will find the correct .gitattributes, and give them a saner diff header). We still have to fall back to using the name for some cases (i.e., any blob reference that isn't of the form tree:path). That's the best we can do in such a case.

2017-05-24diff: pass whole pending entry in blobinfoLibravatar Jeff King1-23/+15
When diffing blobs directly, git-diff picks the blobs out of the rev_info's pending array and copies the relevant bits to a custom "struct blobinfo". But the pending array entry already has all of this information (and more, which we'll use in future patches). Let's just pass the original entry instead. In practice, these two blobs are probably adjacent in the revs->pending array, and we could just pass the whole array. But the current code is careful to pick each blob out separately and put it into another array, so we'll continue to do so and make our own array-of-pointers.

2017-05-24get_sha1_with_context: dynamically allocate oc->pathLibravatar Jeff King3-5/+13
When a sha1 lookup returns the tree path via "struct object_context", it just copies it into a fixed-size buffer. This means the result can be truncated, and it means our "struct object_context" consumes a lot of stack space. Instead, let's allocate a string on the heap. Because most callers don't care about this information, we'll avoid doing it by default (so they don't all have to start calling free() on the result). There are basically two options for the caller to signal to us that it's interested: 1. By setting a pointer to storage in the object_context. 2. By passing a flag in another parameter. Doing (1) would match the way that sha1_object_info_extended() works. But it would mean that every caller would have to initialize the object_context, which they don't currently have to do. This patch does (2), and adds a new bit to the function's flags field. All of the callers that look at the "path" field are updated to pass the new flag.

2017-05-24clean: teach clean -d to preserve ignored pathsLibravatar Samuel Lijin1-0/+42
There is an implicit assumption that a directory containing only untracked and ignored paths should itself be considered untracked. This makes sense in use cases where we're asking if a directory should be added to the git database, but not when we're asking if a directory can be safely removed from the working tree; as a result, clean -d would assume that an "untracked" directory containing ignored paths could be deleted, even though doing so would also remove the ignored paths. To get around this, we teach clean -d to collect ignored paths and skip an untracked directory if it contained an ignored path, instead just removing the untracked contents thereof. To achieve this, cmd_clean() has to collect all untracked contents of untracked directories, in addition to all ignored paths, to determine which untracked dirs must be skipped (because they contain ignored paths) and which ones should *not* be skipped. For this purpose, correct_untracked_entries() is introduced to prune a given dir_struct of untracked entries containing ignored paths and those untracked entries encompassed by the untracked entries which are not pruned away. A memory leak is also fixed in cmd_clean(). This also fixes the known breakage in t7300, since clean -d now skips untracked directories containing ignored paths.

This can easily be seen with: $ GIT_EDITOR='git interpret-trailers --in-place --trailer Acked-by:me' \ git commit --amend -v Teach "git interpret-trailers" to notice the cut-line and ignore the remainder of the input when looking for a place to add new trailer block. This makes it consistent with how "git commit -v -s" inserts a new Signed-off-by: line. This can be done by the same logic as the existing helper function, wt_status_truncate_message_at_cut_line(), uses, but it wants the caller to pass a strbuf to it. Because the function ignore_non_trailer() used by the command takes a <pointer, length> pair, not a strbuf, steal the logic from wt_status_truncate_message_at_cut_line() to create a new wt_status_locate_end() helper function that takes <pointer, length> pair, and make ignore_non_trailer() call it to help "interpret-trailers". Since there is only one caller of wt_status_truncate_message_at_cut_line() in cmd_commit(), rewrite it to call wt_status_locate_end() helper instead and remove the old helper that no longer has any caller.

The recent change that introduced autodecorating of refs accidentally broke the ability of users to set log.decorate = false to override it. When the git_log_config was traversed a second time with an option other than log.decorate, the decoration style would be set to the automatic style, even if the user had already overridden it. Instead of setting the option in config parsing, set it in init_log_defaults instead. Add a test for this case.

2017-05-15config: complain about --local outside of a git repoLibravatar Jeff King1-0/+3
The "--local" option instructs git-config to read or modify the repository-level config. This doesn't make any sense if you're not actually in a repository. Older versions of Git would blindly try to read or write ".git/config". For reading, this would result in a quiet failure, since there was no config to read (and thus no matching config value). Writing would generally fail noisily, since ".git" was unlikely to exist. But since b1ef400ee (setup_git_env: avoid blind fall-back to ".git", 2016-10-20), we catch this in the call to git_pathdup() and die with an assertion. Dying is the right thing to do, but we should catch the problem early and give a more human-friendly error message. Note that even without --local, git-config will sometimes default to using local repository config (e.g., when writing). These cases are already protected by similar checks, and covered by a test in t1308. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-05-12usability: don't ask questions if no reply is requiredLibravatar Jean-Noel Avila2-5/+5
There has been a bug report by a corporate user that stated that "spelling mistake of stash followed by a yes prints character 'y' infinite times." This analysis was false. When the spelling of a command contains errors, the git program tries to help the user by providing candidates which are close to the unexisting command. E.g Git prints the following: git: 'stahs' is not a git command. See 'git --help'. Did you mean this? stash and then exits. The problem with this hint is that it is not formally indicated as an hint and the user is in fact encouraged to reply to the question, whereas the Git command is already finished. The user was unlucky enough that it was the command he was looking for, and replied "yes" on the command line, effectively launching the `yes` program. The initial error is that the Git programs, when launched in command-line mode (without interaction) must not ask questions, because these questions would normally require a user input as a reply that they won't handle indeed. That's a source of confusion on UX level. To improve the general usability of the Git suite, the following rule was applied: if the sentence * appears in a non-interactive session * is printed last before exit * is a question addressing the user ("you") the sentence is turned into affirmative and proposes the option. The basic rewording of the question sentences has been extended to other spots found in the source.

2017-05-10read-tree: "read-tree -m --empty" does not make senseLibravatar Junio C Hamano1-1/+1
fb1bb965 ("read-tree: deprecate syntax without tree-ish args", 2010-09-10) wanted to deprecate "git read-tree" without any tree, which used to be the way to empty the index, and encourage use of "git read-tree --empty" instead. However, when used with "-m", "--empty" does not make any sense, either, simply because merging 0 trees will result in a different error anyway. Omit the deprecation warning and let the code to emit real error message diagnose the error. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-05-10receive-pack: verify push options in certLibravatar Jonathan Tan1-2/+49
In commit f6a4e61 ("push: accept push options", 2016-07-14), send-pack was taught to include push options both within the signed cert (if the push is a signed push) and outside the signed cert; however, receive-pack ignores push options within the cert, only handling push options outside the cert. Teach receive-pack, in the case that push options are provided for a signed push, to verify that the push options both within the cert and outside the cert are consistent. This sets in stone the requirement that send-pack redundantly send its push options in 2 places, but I think that this is better than the alternatives. Sending push options only within the cert is backwards-incompatible with existing Git servers (which read push options only from outside the cert), and sending push options only outside the cert means that the push options are not signed for.

2017-05-09pack-objects: disable pack reuse for object-selection optionsLibravatar Jeff King1-1/+5
If certain options like --honor-pack-keep, --local, or --incremental are used with pack-objects, then we need to feed each potential object to want_object_in_pack() to see if it should be filtered out. But when the bitmap reuse_packfile optimization is in effect, we do not call that function at all, and in fact skip adding the objects to the to_pack list entirely. This means we have a bug: for certain requests we will silently ignore those options and include objects in that pack that should not be there. The problem has been present since the inception of the pack-reuse code in 6b8fda2db (pack-objects: use bitmaps when packing objects, 2013-12-21), but it was unlikely to come up in practice. These options are generally used for on-disk packing, not transfer packs (which go to stdout), but we've never allowed pack reuse for non-stdout packs (until 645c432d6, we did not even use bitmaps, which the reuse optimization relies on; after that, we explicitly turned it off when not packing to stdout). We can fix this by just disabling the reuse_packfile optimization when the options are in use. In theory we could teach the pack-reuse code to satisfy these checks, but it's not worth the complexity. The purpose of the optimization is to keep the amount of per-object work we do to a minimum. But these options inherently require us to search for other copies of each object, drowning out any benefit of the pack-reuse optimization. But note that the optimizations from 56dfeb626 (pack-objects: compute local/ignore_pack_keep early, 2016-07-29) happen before pack-reuse, meaning that specifying "--honor-pack-keep" in a repository with no .keep files can still follow the fast path. There are tests in t5310 that check these options with bitmaps and --stdout, but they didn't catch the bug, and it's hard to adapt them to do so. One problem is that they don't use --delta-base-offset; without that option, we always disable the reuse optimization entirely. It would be fine to add it in (it actually makes the test more realistic), but that still isn't quite enough. The other problem is that the reuse code is very picky; it only kicks in when it can reuse most of a pack, starting from the first byte. So we'd have to start from a fully repacked and bitmapped state to trigger it. But the tests for these options use a much more subtle state; they want to be sure that the want_object_in_pack() code is allowing some objects but not others. Doing a full repack runs counter to that. So this patch adds new tests at the end of the script which create the fully-packed state and make sure that each option is not fooled by reusable pack.
