2020-10-12grep: handle deref_tag() returning NULLLibravatar René Scharfe1-0/+11
deref_tag() can return NULL. Exit gracefully in that case instead of blindly dereferencing the return value. .name shouldn't ever be NULL, but grep_object() handles that case explicitly, so let's be defensive here as well and show the broken object's ID if it happens to lack a name after all.

2020-10-07index-pack: drop type_cas mutexLibravatar Jeff King1-6/+0
The type_cas lock lost all of its callers in f08cbf60fe (index-pack: make quantum of work smaller, 2020-09-08), so we can safely delete it. The compiler didn't alert us that the variable became unused, because we still call pthread_mutex_init() and pthread_mutex_destroy() on it. It's worth considering also whether that commit was in error to remove the use of the lock. Why don't we need it now, if we did before, as described in ab791dd138 (index-pack: fix race condition with duplicate bases, 2014-08-29)? I think the answer is that we now look at and assign the child_obj->real_type field in the main thread while holding the work_lock(). So we don't have to worry about racing with the worker threads.

2020-10-07index-pack: restore "resolving deltas" progress meterLibravatar Jeff King1-0/+4
Commit f08cbf60fe (index-pack: make quantum of work smaller, 2020-09-08) refactored the main loop in threaded_second_pass(), but also deleted the call to display_progress() at the top of the loop. This means that users typically see no progress at all during the delta resolution phase (and for large repositories, Git appears to hang). This looks like an accident that was unrelated to the intended change of that commit, since we continue to update nr_resolved_deltas in resolve_delta(). Let's restore the call to get that progress back. We'll also add a test that confirms we generate the expected progress. This isn't perfect, as it wouldn't catch a bug where progress was delayed to the end. That was probably possible to trigger when receiving a thin pack, because we'd eventually call display_progress() from fix_unresolved_deltas(), but only once after doing all the work. However, since our test case generates a complete pack, it reliably demonstrates this particular bug and its fix. And we can't do better without making the test racy.

2020-10-01format-patch: teach format.useAutoBase "whenAble" optionLibravatar Jacob Keller1-25/+105
The format.useAutoBase configuration option exists to allow users to enable '--base=auto' for format-patch by default. This can sometimes lead to poor workflow, due to unexpected failures when attempting to format an ancient patch: $ git format-patch -1 <an old commit> fatal: base commit shouldn't be in revision list This can be very confusing, as it is not necessarily immediately obvious that the user requested a --base (since this was in the configuration, not on the command line). We do want --base=auto to fail when it cannot provide a suitable base, as it would be equally confusing if a formatted patch did not include the base information when it was requested. Teach format.useAutoBase a new mode, "whenAble". This mode will cause format-patch to attempt to include a base commit when it can. However, if no valid base commit can be found, then format-patch will continue formatting the patch without a base commit. In order to avoid making yet another branch name unusable with --base, do not teach --base=whenAble or --base=whenable. Instead, refactor the base_commit option to use a callback, and rely on the global configuration variable auto_base. This does mean that a user cannot request this optional base commit generation from the command line. However, this is likely not too valuable. If the user requests base information manually, they will be immediately informed of the failure to acquire a suitable base commit. This allows the user to make an informed choice about whether to continue the format. Add tests to cover the new mode of operation for --base.

2020-09-30refspec: add support for negative refspecsLibravatar Jacob Keller1-0/+10
Both fetch and push support pattern refspecs which allow fetching or pushing references that match a specific pattern. Because these patterns are globs, they have somewhat limited ability to express more complex situations. For example, suppose you wish to fetch all branches from a remote except for a specific one. To allow this, you must setup a set of refspecs which match only the branches you want. Because refspecs are either explicit name matches, or simple globs, many patterns cannot be expressed. Add support for a new type of refspec, referred to as "negative" refspecs. These are prefixed with a '^' and mean "exclude any ref matching this refspec". They can only have one "side" which always refers to the source. During a fetch, this refers to the name of the ref on the remote. During a push, this refers to the name of the ref on the local side. With negative refspecs, users can express more complex patterns. For example: git fetch origin refs/heads/*:refs/remotes/origin/* ^refs/heads/dontwant will fetch all branches on origin into remotes/origin, but will exclude fetching the branch named dontwant. Refspecs today are commutative, meaning that order doesn't expressly matter. Rather than forcing an implied order, negative refspecs will always be applied last. That is, in order to match, a ref must match at least one positive refspec, and match none of the negative refspecs. This is similar to how negative pathspecs work.

The sparse-checkout passes along argv and argc to its sub-command helper functions. Many of these sub-commands do not yet take any command-line options, and ignore those parameters. Let's instead add empty option lists and make sure we call parse_options(). That will give a useful error message for something like: git sparse-checkout list --nonsense which currently just silently ignores the unknown option.

In the spirit of 517fe807d6 (assert NOARG/NONEG behavior of parse-options callbacks, 2018-11-05), let's cover some parse-options callbacks which expect to be used with PARSE_OPT_NONEG but don't explicitly assert that this is the case. These callbacks are all used correctly in the current code, but this will help document their expectations and future-proof the code.

2020-09-30env--helper: write to opt->value in parseopt helperLibravatar Jeff King1-4/+7
We use OPT_CALLBACK_F() to call the option_parse_type() callback, passing it the address of "cmdmode" as the value to write to. But the callback doesn't look at opt->value at all, and instead writes to a global variable. This works out because that's the same global variable we happen to pass in, but it's rather confusing. Let's use the passed-in value instead. We'll also make "cmdmode" a local variable of the main function, ensuring we can't make the same mistake again.

2020-09-30drop unused argc parametersLibravatar Jeff King2-8/+8
Many functions take an argv/argc pair, but never actually look at argc. This makes it useless at best (we use the NULL sentinel in argv to find the end of the array), and misleading at worst (what happens if the argc count does not match the argv NULL?). In each of these instances, the argv NULL does match the argc count, so there are no bugs here. But let's tighten the interfaces to make it harder to get wrong (and to reduce some -Wunused-parameter complaints).

2020-09-28fetch: do not override partial clone filterLibravatar Jonathan Tan1-1/+1
When a fetch with the --filter argument is made, the configured default filter is set even if one already exists. This change was made in 5e46139376 ("builtin/fetch: remove unique promisor remote limitation", 2019-06-25) - in particular, changing from: * If this is the FIRST partial-fetch request, we enable partial * on this repo and remember the given filter-spec as the default * for subsequent fetches to this remote. to: * If this is a partial-fetch request, we enable partial on * this repo if not already enabled and remember the given * filter-spec as the default for subsequent fetches to this * remote. (The given filter-spec is "remembered" even if there is already an existing one.) This is problematic whenever a lazy fetch is made, because lazy fetches are made using "git fetch --filter=blob:none", but this will also happen if the user invokes "git fetch --filter=<filter>" manually. Therefore, restore the behavior prior to 5e46139376, which writes a filter-spec only if the current fetch request is the first partial-fetch one (for that remote).

2020-09-27shortlog: allow multiple groups to be specifiedLibravatar Jeff King2-24/+41
Now that shortlog supports reading from trailers, it can be useful to combine counts from multiple trailers, or between trailers and authors. This can be done manually by post-processing the output from multiple runs, but it's non-trivial to make sure that each name/commit pair is counted only once. This patch teaches shortlog to accept multiple --group options on the command line, and pull data from all of them. That makes it possible to run: git shortlog -ns --group=author --group=trailer:co-authored-by to get a shortlog that counts authors and co-authors equally. The implementation is mostly straightforward. The "group" enum becomes a bitfield, and the trailer key becomes a list. I didn't bother implementing the multi-group semantics for reading from stdin. It would be possible to do, but the existing matching code makes it awkward, and I doubt anybody cares. The duplicate suppression we used for trailers now covers authors and committers as well (though in non-trailer single-group mode we can skip the hash insertion and lookup, since we only see one value per commit). There is one subtlety: we now care about the case when no group bit is set (in which case we default to showing the author). The caller in builtin/log.c needs to be adapted to ask explicitly for authors, rather than relying on shortlog_init(). It would be possible with some gymnastics to make this keep working as-is, but it's not worth it for a single caller.

2020-09-27shortlog: parse trailer identsLibravatar Jeff King1-0/+6
Trailers don't necessarily contain name/email identity values, so shortlog has so far treated them as opaque strings. However, since many trailers do contain identities, it's useful to treat them as such when they can be parsed. That lets "-e" work as usual, as well as mailmap. When they can't be parsed, we'll continue with the old behavior of treating them as a single string (there's no new test for that here, since the existing tests cover a trailer like this).

In 06f5608c14 (bisect--helper: `bisect_start` shell function partially in C, 2019-01-02), we changed the following shell code: - rev=$(git rev-parse -q --verify "$arg^{commit}") || { - test $has_double_dash -eq 1 && - die "$(eval_gettext "'\$arg' does not appear to be a valid revision")" - break - } - revs="$revs $rev" into: + char *commit_id = xstrfmt("%s^{commit}", arg); + if (get_oid(commit_id, &oid) && has_double_dash) + die(_("'%s' does not appear to be a valid " + "revision"), arg); + + string_list_append(&revs, oid_to_hex(&oid)); + free(commit_id); In case of an invalid "arg" when "has_double_dash" is false, the old code would "break" out of the argument loop. In the new C code though, `oid_to_hex(&oid)` is unconditonally appended to "revs". This is wrong first because "oid" is junk as `get_oid(commit_id, &oid)` failed and second because it doesn't break out of the argument loop. Not breaking out of the argument loop means that "arg" is then not treated as a path restriction (which is wrong).

As more functions are ported, `--bisect-auto-next` subcommand will be retired and will be called by some other methods.

2020-09-24bisect--helper: reimplement `bisect_autostart` shell function in CLibravatar Pranit Bauva1-1/+43
Reimplement the `bisect_autostart()` shell function in C and add the C implementation from `bisect_next()` which was previously left uncovered. Add `--bisect-autostart` subcommand to be called from git-bisect.sh. Using `--bisect-autostart` subcommand is a temporary measure to port the shell function to C so as to use the existing test suite. As more functions are ported, this subcommand will be retired and bisect_autostart() will be called directly by `bisect_state()`. Change behavior of shell script that returned success when user aborted the bisection.

2020-09-22Merge branch 'ar/fetch-ipversion-in-all'Libravatar Junio C Hamano1-1/+4
"git fetch --all --ipv4/--ipv6" forgot to pass the protocol options to instances of the "git fetch" that talk to individual remotes, which has been corrected. * ar/fetch-ipversion-in-all: fetch: pass --ipv4 and --ipv6 options to sub-fetches
2020-09-22Merge branch 'cs/don-t-pretend-a-failed-remote-set-head-succeeded'Libravatar Junio C Hamano1-1/+1
"git remote set-head" that failed still said something that hints the operation went through, which was misleading. * cs/don-t-pretend-a-failed-remote-set-head-succeeded: remote: don't show success message when set-head fails
2020-09-22Merge branch 'al/ref-filter-merged-and-no-merged'Libravatar Junio C Hamano3-8/+8
"git for-each-ref" and friends that list refs used to allow only one --merged or --no-merged to filter them; they learned to take combination of both kind of filtering. * al/ref-filter-merged-and-no-merged: Doc: prefer more specific file name ref-filter: make internal reachable-filter API more precise ref-filter: allow merged and no-merged filters Doc: cover multiple contains/no-contains filters t3201: test multiple branch filter combinations
2020-09-22Merge branch 'ls/mergetool-meld-auto-merge'Libravatar Junio C Hamano1-0/+17
The 'meld' backend of the "git mergetool" learned to give the underlying 'meld' the '--auto-merge' option, which would help reduce the amount of text that requires manual merging. * ls/mergetool-meld-auto-merge: mergetool: allow auto-merge for meld to follow the vim-diff behavior
