2017-08-15interpret-trailers: add --parse convenience optionJeff King
The last few commits have added command line options that can turn interpret-trailers into a parsing tool. Since they'd most often be used together, let's provide a convenient single option for callers to invoke this mode. This is implemented as a callback rather than a boolean so that its effect is applied immediately, as if those options had been specified. Later options can then override them. E.g.: git interpret-trailers --parse --no-unfold would work. Let's also update the documentation to make clear that this parsing mode behaves quite differently than the normal "add trailers to the input" mode.

2017-08-15interpret-trailers: add an option to unfold valuesJeff King
The point of "--only-trailers" is to give a caller an output that's easy for them to parse. Getting rid of the non-trailer material helps, but we still may see more complicated syntax like whitespace continuation. Let's add an option to unfold any continuation, giving the output as a single "key: value" line per trailer. As a bonus, this could be used even without --only-trailers to clean up unusual formatting in the incoming data.

2017-08-15interpret-trailers: add an option to show only existing trailersJeff King
It can be useful to invoke interpret-trailers for the primary purpose of parsing existing trailers. But in that case, we don't want to apply existing ifMissing or ifExists rules from the config. Let's add a special mode where we avoid applying those rules. Coupled with --only-trailers, this gives us a reasonable parsing tool.

2017-08-15interpret-trailers: add an option to show only the trailersJeff King
In theory it's easy for any reader who wants to parse trailers to do so. But there are a lot of subtle corner cases around what counts as a trailer, when the trailer block begins and ends, etc. Since interpret-trailers already has our parsing logic, let's let callers ask it to just output the trailers. They still have to parse the "key: value" lines, but at least they can ignore all of the other corner cases. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-07-31Merge branch 'jk/gc-pre-detach-under-hook' into maintJunio C Hamano
We run an early part of "git gc" that deals with refs before daemonising (and not under lock) even when running a background auto-gc, which caused multiple gc processes attempting to run the early part at the same time. This is now prevented by running the early part also under the GC lock. * jk/gc-pre-detach-under-hook: gc: run pre-detach operations under lock

2017-07-12gc: run pre-detach operations under lockJeff King
We normally try to avoid having two auto-gc operations run at the same time, because it wastes resources. This was done long ago in 64a99eb47 (gc: reject if another gc is running, unless --force is given, 2013-08-08). When we do a detached auto-gc, we run the ref-related commands _before_ detaching, to avoid confusing lock contention. This was done by 62aad1849 (gc --auto: do not lock refs in the background, 2014-05-25). These two features do not interact well. The pre-detach operations are run before we check the gc.pid lock, meaning that on a busy repository we may run many of them concurrently. Ideally we'd take the lock before spawning any operations, and hold it for the duration of the program. This is tricky, though, with the way the pid-file interacts with the daemonize() process. Other processes will check that the pid recorded in the pid-file still exists. But detaching causes us to fork and continue running under a new pid. So if we take the lock before detaching, the pid-file will have a bogus pid in it. We'd have to go back and update it with the new pid after detaching. We'd also have to play some tricks with the tempfile subsystem to tweak the "owner" field, so that the parent process does not clean it up on exit, but the child process does. Instead, we can do something a bit simpler: take the lock only for the duration of the pre-detach work, then detach, then take it again for the post-detach work. Technically, this means that the post-detach lock could lose to another process doing pre-detach work. But in the long run this works out. That second process would then follow-up by doing post-detach work. Unless it was in turn blocked by a third process doing pre-detach work, and so on. This could in theory go on indefinitely, as the pre-detach work does not repack, and so need_to_gc() will continue to trigger. But in each round we are racing between the pre- and post-detach locks. Eventually, one of the post-detach locks will win the race and complete the full gc. So in the worst case, we may racily repeat the pre-detach work, but we would never do so simultaneously (it would happen via a sequence of serialized race-wins).

2017-07-09branch: set remote color in ref-filter branch immediatelyJeff King
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.

2017-07-09branch: use BRANCH_COLOR_LOCAL in ref-filter formatJeff King
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 branchesJeff King
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.

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.

2017-05-31C style: use standard style for "TRANSLATORS" commentsÆvar Arnfjörð Bjarmason
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 earlierJeff King
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 diffsJeff King
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 availableJeff King
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 blobinfoJeff King
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->pathJeff King
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 pathsSamuel Lijin
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.

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.

2017-05-15builtin/log: honor log.decoratebrian m. carlson
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. The actual additional config option doesn't matter, but it needs to be something not already set in the configuration file.

2017-05-15config: complain about --local outside of a git repoJeff King
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>
2017-05-12read-tree -m: make error message for merging 0 trees less smart aleckJean-Noel Avila
"git read-tree -m" requires a tree argument to name the tree to be merged in. Git uses a cutesy error message to say so and why: $ git read-tree -m warning: read-tree: emptying the index with no arguments is deprecated; use --empty fatal: just how do you expect me to merge 0 trees? $ git read-tree -m --empty fatal: just how do you expect me to merge 0 trees? When lucky, that could produce an ah-hah moment for the user, but it's more likely to irritate and distract them. Instead, tell the user plainly that the tree argument is required. Also document this requirement in the git-read-tree(1) manpage where there is room to explain it in a more straightforward way.

2017-05-12usability: don't ask questions if no reply is requiredJean-Noel Avila
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.

2017-05-11read-tree: "read-tree -m --empty" does not make senseJunio C Hamano
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 certJonathan Tan
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.
