Commit e8cbe2118a (am: stop exporting GIT_COMMITTER_DATE, 2020-08-17) rewrote the code for setting the committer date to use fmt_ident(), rather than setting an environment variable and letting commit_tree() handle it. But it introduced two bugs: - we use the author email string instead of the committer email - when parsing the committer ident, we used the wrong variable to compute the length of the email, resulting in it always being a zero-length string This commit fixes both, which causes our test of this option via the rebase "apply" backend to now succeed.

2020-10-12worktree: teach `list` to annotate locked worktreeLibravatar Rafael Silva1-1/+4
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>

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.

2020-10-03push: parse and set flag for "--force-if-includes"Libravatar Srinidhi Kaushik2-0/+33
The previous commit added the necessary machinery to implement the "--force-if-includes" protection, when "--force-with-lease" is used without giving exact object the remote still ought to have. Surface the feature by adding a command line option and a configuration variable to enable it. - Add a flag: "TRANSPORT_PUSH_FORCE_IF_INCLUDES" to indicate that the new option was passed from the command line of via configuration settings; update command line and configuration parsers to set the new flag accordingly. - Introduce a new configuration option "push.useForceIfIncludes", which is equivalent to setting "--force-if-includes" in the command line. - Update "remote-curl" to recognize and pass this option to "send-pack" when enabled. - Update "advise" to catch the reject reason "REJECT_REF_NEEDS_UPDATE", set when the ref status is "REF_STATUS_REJECT_REMOTE_UPDATED" and (optionally) print a help message when the push fails. - The new option is a "no-op" in the following scenarios: * When used without "--force-with-lease". * When used with "--force-with-lease", and if the expected commit on the remote side is specified as an argument.

2020-10-03push: add reflog check for "--force-if-includes"Libravatar Srinidhi Kaushik1-0/+5
Add a check to verify if the remote-tracking ref of the local branch is reachable from one of its "reflog" entries. The check iterates through the local ref's reflog to see if there is an entry for the remote-tracking ref and collecting any commits that are seen, into a list; the iteration stops if an entry in the reflog matches the remote ref or if the entry timestamp is older the latest entry of the remote ref's "reflog". If there wasn't an entry found for the remote ref, "in_merge_bases_many()" is called to check if it is reachable from the list of collected commits. When a local branch that is based on a remote ref, has been rewound and is to be force pushed on the remote, "--force-if-includes" runs a check that ensures any updates to the remote-tracking ref that may have happened (by push from another repository) in-between the time of the last update to the local branch (via "git-pull", for instance) and right before the time of push, have been integrated locally before allowing a forced update. If the new option is passed without specifying "--force-with-lease", or specified along with "--force-with-lease=<refname>:<expect>" it is a "no-op".

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.

Providing a bad origin name to `git clone` currently reports an 'invalid refspec' error instead of a more explicit message explaining that the `--origin` option was malformed. This behavior dates back to since 8434c2f1 (Build in clone, 2008-04-27). Reintroduce validation for the provided `--origin` option, but notably _don't_ include a multi-level check (e.g. "foo/bar") that was present in the original `git-clone.sh`. `git remote` allows multi-level remote names since at least 46220ca100 (remote.c: Fix overtight refspec validation, 2008-03-20), so that appears to be the desired behavior.

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.

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).

2020-09-29Merge branch 'ah/pull'Libravatar Junio C Hamano1-2/+1
Earlier we taught "git pull" to warn when the user does not say the histories need to be merged, rebased or accepts only fast- forwarding, but the warning triggered for those who have set the pull.ff configuration variable. * ah/pull: pull: don't warn if pull.ff has been set
2020-09-29Merge branch 'bc/clone-with-git-default-hash-fix'Libravatar Junio C Hamano2-3/+5
"git clone" that clones from SHA-1 repository, while GIT_DEFAULT_HASH set to use SHA-256 already, resulted in an unusable repository that half-claims to be SHA-256 repository with SHA-1 objects and refs. This has been corrected. * bc/clone-with-git-default-hash-fix: builtin/clone: avoid failure with GIT_DEFAULT_HASH
2020-09-29Merge branch 'tb/bloom-improvements'Libravatar Junio C Hamano1-13/+50
"git commit-graph write" learned to limit the number of bloom filters that are computed from scratch with the --max-new-filters option. * tb/bloom-improvements: commit-graph: introduce 'commitGraph.maxNewFilters' builtin/commit-graph.c: introduce '--max-new-filters=<n>' commit-graph: rename 'split_commit_graph_opts' bloom: encode out-of-bounds filters as non-empty bloom/diff: properly short-circuit on max_changes bloom: use provided 'struct bloom_filter_settings' bloom: split 'get_bloom_filter()' in two commit-graph.c: store maximum changed paths commit-graph: respect 'commitGraph.readChangedPaths' t/helper/test-read-graph.c: prepare repo settings commit-graph: pass a 'struct repository *' in more places t4216: use an '&&'-chain commit-graph: introduce 'get_bloom_filter_settings()'
2020-09-29diff: get rid of redundant 'dense' argumentLibravatar Sergey Organov1-2/+1
Get rid of 'dense' argument that is redundant for every function that has 'struct rev_info *rev' argument as well, as the value of 'dense' passed is always taken from 'rev->dense_combined_merges' field. The only place where this was not the case is in 'submodule.c' where 'diff_tree_combined_merge()' was called with '1' for 'dense' argument. However, at that call the 'revs' instance used is local to the function, and we now just set 'revs->dense_combined_merges' to 1 in this local instance.
