2020-11-04doc: clarify that --abbrev=<n> is about the minimum lengthLibravatar Junio C Hamano6-11/+18
Early text written in 2006 explains the "--abbrev=<n>" option to "show only a partial prefix", without saying that the length of the partial prefix is not necessarily the number given to the option to ensure that the output names the object uniquely. Update documentation for the diff family of commands, "blame", "branch --verbose", "ls-files" and "ls-tree" to stress that the short prefix must uniquely refer to an object, and <n> is merely the mininum number of hexdigits used in the prefix.

2020-10-27remote: add meaningful exit code on missing/existingLibravatar Ævar Arnfjörð Bjarmason1-0/+11
Change the exit code for the likes of "git remote add/rename" to exit with 2 if the remote in question doesn't exist, and 3 if it does. Before we'd just die() and exit with the general 128 exit code. This changes the output message from e.g.: fatal: remote origin already exists. To: error: remote origin already exists. Which I believe is a feature, since we generally use "fatal" for the generic errors, and "error" for the more specific ones with a custom exit code, but this part of the change may break code that already relies on stderr parsing (not that we ever supported that...). The motivation for this is a discussion around some code in GitLab's gitaly which wanted to check this, and had to parse stderr to do so: https://gitlab.com/gitlab-org/gitaly/-/merge_requests/2695 It's worth noting as an aside that a method of checking this that doesn't rely on that is to check with "git config" whether the value in question does or doesn't exist. That introduces a TOCTOU race condition, but on the other hand this code (e.g. "git remote add") already has a TOCTOU race. We go through the config.lock for the actual setting of the config, but the pseudocode logic is: read_config(); check_config_and_arg_sanity(); save_config(); So e.g. if a sleep() is added right after the remote_is_configured() check in add() we'll clobber remote.NAME.url, and add another (usually duplicate) remote.NAME.fetch entry (and other values, depending on invocation).

Support POSIX, bashism and mixed function declarations, all four compound command types, trailing comments and mixed whitespace. Even though Bash allows locale-dependent characters in function names <https://unix.stackexchange.com/a/245336/3645>, only detect function names with characters allowed by POSIX.1-2017 <https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_235> for simplicity. This should cover the vast majority of use cases, and produces system-agnostic results. Since a word pattern has to be specified, but there is no easy way to know the default word pattern, use the default `IFS` characters for a starter. A later patch can improve this.

2020-10-20diff: add -I<regex> that ignores matching changesLibravatar Michał Kępień1-0/+5
Add a new diff option that enables ignoring changes whose all lines (changed, removed, and added) match a given regular expression. This is similar to the -I/--ignore-matching-lines option in standalone diff utilities and can be used e.g. to ignore changes which only affect code comments or to look for unrelated changes in commits containing a large number of automatically applied modifications (e.g. a tree-wide string replacement). The difference between -G/-S and the new -I option is that the latter filters output on a per-change basis. Use the 'ignore' field of xdchange_t for marking a change as ignored or not. Since the same field is used by --ignore-blank-lines, identical hunk emitting rules apply for --ignore-blank-lines and -I. These two options can also be used together in the same git invocation (they are complementary to each other). Rename xdl_mark_ignorable() to xdl_mark_ignorable_lines(), to indicate that it is logically a "sibling" of xdl_mark_ignorable_regex() rather than its "parent".

2020-10-20Documentation: stylistically normalize references to Signed-off-by:Libravatar Bradley M. Kuhn12-18/+18
Ted reported an old typo in the git-commit.txt and merge-options.txt. Namely, the phrase "Signed-off-by line" was used without either a definite nor indefinite article. Upon examination, it seems that the documentation (including items in Documentation/, but also option help strings) have been quite inconsistent on usage when referring to `Signed-off-by`. First, very few places used a definite or indefinite article with the phrase "Signed-off-by line", but that was the initial typo that led to this investigation. So, normalize using either an indefinite or definite article consistently. The original phrasing, in Commit 3f971fc425b (Documentation updates, 2005-08-14), is "Add Signed-off-by line". Commit 6f855371a53 (Add --signoff, --check, and long option-names. 2005-12-09) switched to using "Add `Signed-off-by:` line", but didn't normalize the former commit to match. Later commits seem to have cut and pasted from one or the other, which is likely how the usage became so inconsistent. Junio stated on the git mailing list in <xmqqy2k1dfoh.fsf@gitster.c.googlers.com> a preference to leave off the colon. Thus, prefer `Signed-off-by` (with backticks) for the documentation files and Signed-off-by (without backticks) for option help strings. Additionally, Junio argued that "trailer" is now the standard term to refer to `Signed-off-by`, saying that "becomes plenty clear that we are not talking about any random line in the log message". As such, prefer "trailer" over "line" anywhere the former word fits. However, leave alone those few places in documentation that use Signed-off-by to refer to the process (rather than the specific trailer), or in places where mail headers are generally discussed in comparison with Signed-off-by.

The description on sign-off and DCO was written back in the days where there was only a choice between "use sign-off and it means the contributor agrees to the Linux-kernel style DCO" and "not using sign-off at all will make your patch unusable". These days, we are trying to clarify that the exact meaning of a sign-off varies project to project. Let's be more explicit when presenting what _our_ rules are. It is of secondary importance that it originally came from the kernel project, so move the description as a historical note at the end, while cautioning that what a sign-off means to us may be different from what it means to other projects contributors may have been used to.

However, leave intact reference to the Linux DCO, which Git also uses.

2020-10-20doc: preparatory clean-up of description on the sign-off optionLibravatar Junio C Hamano3-18/+17
Almost identical text on the signed-off-by trailer appears in the documentation for "git commit" and "git merge" and its friends. Introduce a new signoff-option.txt file to be shared. A couple of things of note are: - The short-form "-s" is available only in "git commit", but not in commands that are friends of "git merge", as it is used as a short-hand for "--strategy". - The original lacks description on the negated "--no-signoff" form on "git commit" side, but it equally is applicable. It however was unclear in the original text that not adding a Signed-off-by trailer is the default, so rephrase to explain it as a way to countermand a --signoff option that appeared earlier on the same command line. This is in preparation to apply a further clarification on what exactly the Signed-off-by trailer means.

2020-10-16t6423: more involved rules for renaming directories into each otherLibravatar Elijah Newren1-0/+3
Testcases 12b and 12c were both slightly weird; they were marked as having a weird resolution, but with the note that even straightforward simple rules can give weird results when the input is bizarre. However, during optimization work for merge-ort, I discovered a significant speedup that is possible if we add one more fairly straightforward rule: we don't bother doing directory rename detection if there are no new files added to the directory on the other side of the history to be affected by the directory rename. This seems like an obvious and straightforward rule, but there was one funny corner case where directory rename detection could affect only existing files: the funny corner case where two directories are renamed into each other on opposite sides of history. In other words, it only results in a different output for testcases 12b and 12c. Since we already thought testcases 12b and 12c were weird anyway, and because the optimization often has a significant effect on common cases (but is entirely prevented if we can't change how 12b and 12c function), let's add the additional rule and tweak how 12b and 12c work. Split both testcases into two (one where we add no new files, and one where the side that doesn't rename a given directory will add files to it), and mark them with the new expectation.

The "git worktree list" shows the absolute path to the working tree, the commit that is checked out and the name of the branch. It is not immediately obvious which of the worktrees, if any, are locked. "git worktree remove" refuses to remove a locked worktree with an error message. If "git worktree list" told which worktrees are locked in its output, the user would not even attempt to remove such a worktree, or would realize that "git worktree remove -f -f <path>" is required. Teach "git worktree list" to append "locked" to its output. The output from the command becomes like so: $ git worktree list /path/to/main abc123 [master] /path/to/worktree 456def (detached HEAD) /path/to/locked-worktree 123abc (detached HEAD) locked Helped-by: Junio C Hamano <gitster@pobox.com> Helped-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Rafael Silva <rafaeloliveira.cs@gmail.com> Reviewed-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-10-09commit-graph: don't write commit-graph when disabledLibravatar Derrick Stolee1-1/+3
The core.commitGraph config setting can be set to 'false' to prevent parsing commits from the commit-graph file(s). This causes an issue when trying to write with "--split" which needs to distinguish between commits that are in the existing commit-graph layers and commits that are not. The existing mechanism uses parse_commit() and follows by checking if there is a 'graph_pos' that shows the commit was parsed from the commit-graph file. When core.commitGraph=false, we do not parse the commits from the commit-graph and 'graph_pos' indicates that no commits are in the existing file. The --split logic moves forward creating a new layer on top that holds all reachable commits, then possibly merges down into those layers, resulting in duplicate commits. The previous change makes that merging process more robust to such a situation in case it happens in the written commit-graph data. The easy answer here is to avoid writing a commit-graph if reading the commit-graph is disabled. Since the resulting commit-graph will would not be read by subsequent Git processes. This is more natural than forcing core.commitGraph to be true for the 'write' process.
