Phillip Wood 33f2b61ff9 rebase --apply: respect GIT_REFLOG_ACTION
The reflog messages when finishing a rebase hard code "rebase" rather
than using GIT_REFLOG_ACTION.

Phillip Wood da1d63363f rebase --merge: fix reflog when continuing
The reflog message for a conflict resolution committed by "rebase
--continue" looks like

	rebase (continue): commit subject line

Unfortunately the reflog message each subsequent pick look like

	rebase (continue) (pick): commit subject line

Fix this by setting the reflog message for "rebase --continue" in
sequencer_continue() so it does not affect subsequent commits. This
introduces a memory leak similar to the one leaking GIT_REFLOG_ACTION
in pick_commits(). Both of these will be fixed in a future series that
stops the sequencer calling setenv().

If we fail to commit the staged changes then we error out so
GIT_REFLOG_ACTION does not need to be reset in that case.

Phillip Wood 57a1498592 rebase --apply: remove duplicated code
Use move_to_original_branch() when reattaching HEAD after a fast-forward
rather than open coding a copy of that code. move_to_original_branch()
does not call reset_head() if head_name is NULL but there should be no
user visible changes even though we currently call reset_head() in that
case. The reason for this is that the reset_head() call does not add a
message to the reflog because we're not changing the commit that HEAD
points to and so lock_ref_for_update() elides the update. When head_name
is not NULL then reset_head() behaves like "git symbolic-ref" and so the
reflog is updated.

Note that the removal of "strbuf_release(&msg)" is safe as there is an
identical call just above this hunk which can be seen by viewing the
diff with -U6.

Phillip Wood aa1df8146d rebase --keep-base: imply --no-fork-point
Given the name of the option it is confusing if --keep-base actually
changes the base of the branch without --fork-point being explicitly
given on the command line.

The combination of --keep-base with an explicit --fork-point is still
supported even though --fork-point means we do not keep the same base
if the upstream branch has been rewound.  We do this in case anyone is
relying on this behavior which is tested in t3431[1]

Phillip Wood ce5238a690 rebase --keep-base: imply --reapply-cherry-picks
As --keep-base does not rebase the branch it is confusing if it
removes commits that have been cherry-picked to the upstream branch.
As --reapply-cherry-picks is not supported by the "apply" backend this
commit ensures that cherry-picks are reapplied by forcing the upstream
commit to match the onto commit unless --no-reapply-cherry-picks is
given.

Separate out calculating the merge base between 'onto' and 'HEAD' from

Phillip Wood f21becdd94 rebase: store orig_head as a commit
Using a struct commit rather than a struct oid to hold orig_head means
that we error out straight away if the branch being rebased does not
point to a commit. It also simplifies the code that handles finding
the merge base and fork point as it no longer has to convert from an
oid to a commit.

To avoid changing the behavior of "git rebase <upstream> <branch>" we
keep the existing call to read_ref() and use lookup_commit_object()
on the oid returned by that rather than calling
lookup_commit_reference_by_name() which applies the ref dwim rules to
its argument.

Johannes Schindelin df534dcbaa shortlog: use a stable sort
When sorting the output of `git shortlog` by count, a list of authors in
alphabetical order is then sorted by contribution count. Obviously, the
idea is to maintain the alphabetical order for items with identical
contribution count.

At the moment, this job is performed by `qsort()`. As that function is
not guaranteed to implement a stable sort algorithm, this can lead to
inconsistent and/or surprising behavior: items with identical
contribution count could lose their alphabetical sub-order.

The `qsort()` in MS Visual C's runtime does _not_ implement a stable
sort algorithm, and under certain circumstances this even causes a test
failure in t4201.21 "shortlog can match multiple groups", where two
authors both are listed with 2 contributions, and are listed in inverse
alphabetical order.

Let's instead use the stable sort provided by `git_stable_qsort()` to
avoid this inconsistency.

This is a companion to 2049b8dc65 (diffcore_rename(): use a stable sort,
2019-09-30).

Matheus Tavares 611c7785e8 checkout: fix two bugs on the final count of updated entries
At the end of `git checkout <pathspec>`, we get a message informing how
many entries were updated in the working tree. However, this number can
be inaccurate for two reasons:

1) Delayed entries currently get counted twice.
2) Failed entries are included in the count.

The first problem happens because the counter is first incremented
before inserting the entry in the delayed checkout queue, and once again
when finish_delayed_checkout() calls checkout_entry(). And the second
happens because the counter is incremented too early in
checkout_entry(), before the entry was in fact checked out. Fix that by
moving the count increment further down in the call stack and removing
the duplicate increment on delayed entries. Note that we have to keep
a per-entry reference for the counter (both on parallel checkout and
delayed checkout) because not all entries are always accumulated at the
same counter. See checkout_worktree(), at builtin/checkout.c for an
example.

Jeff King 04393ae7f7 diff-files: move misplaced cleanup label
Commit 0139c58ab9 (revisions API users: add "goto cleanup" for
release_revisions(), 2022-04-13) converted an early return in
cmd_diff_files() into a goto. But it put the cleanup label too early: if
read_cache_preload() returns an error, we'll set result to "-1", but
then jump to calling run_diff_files(), overwriting our result.

We should jump past the call to run_diff_files(). Likewise, we should go
past diff_result_code(), which is expecting to see a code from an actual
diff, not a negative error code.

In practice, I suspect this bug cannot actually be triggered, because
read_cache_preload() does not seem to ever return an error. Its return
value (eventually) comes from do_read_index(), which gives the number of
cache entries found, and calls die() on error. Still, it makes sense to
fix the inadvertent change from 0139c58ab9 first, and we can look into
the overall error handling of read_cache() separately (which is present
in many other callsites).

Jeff King daf7898abb clone: move unborn head creation to update_head()
Prior to 4f37d45706 (clone: respect remote unborn HEAD, 2021-02-05),
creation of the local HEAD was always done in update_head(). That commit
added code to handle an unborn head in an empty repository, and just did
all symref creation and config setup there.

This makes the code flow a little bit confusing, especially as new
corner cases have been covered (like the previous commit to match our
default branch name to a non-HEAD remote branch).

Let's move the creation of the unborn symref into update_head(). This
matches the other HEAD-creation cases, and now the logic is consistently
separated: the main cmd_clone() function only examines the situation and
sets variables based on what it finds, and update_head() actually
performs the update.

Jeff King cc8fcd1e1a clone: use remote branch if it matches default HEAD
Usually clone tries to use the same local HEAD as the remote (unless the
user has given --branch explicitly). Even if the remote HEAD is detached
or unborn, we can detect those situations with modern versions of Git.
If the remote is too old to support the "unborn" extension (or it has
been disabled via config), then we can't know the name of the remote's
unborn HEAD, and we fall back whatever the local default branch name is
configured to be.

But that leads to one weird corner case. It's rare because it needs a
number of factors:

  - the remote has an unborn HEAD

  - the remote is too old to support "unborn", or has disabled it

  - the remote has another branch "foo"

  - the local default branch name is "foo"

In that case you end up with a local clone on an unborn "foo" branch,
disconnected completely from the remote's "foo". This is rare in
practice, but the result is quite confusing.

When choosing "foo", we can double check whether the remote has such a
name, and if so, start our local "foo" at the same spot, rather than
making it unborn.

Note that this causes a test failure in t5605, which is cloning from a
bundle that doesn't contain HEAD (so it behaves like a remote that
doesn't support "unborn"), but has a single "main" branch. That test
expects that we end up in the weird "unborn main" case, where we don't
actually check out the remote branch of the same name. Even though we
have to update the test, this seems like an argument in favor of this
patch: checking out main is what I'd expect from such a bundle.

So this patch updates the test for the new behavior and adds an adjacent
one that checks what the original was going for: if there's no HEAD and
the bundle _doesn't_ have a branch that matches our local default name,
then we end up with nothing checked out.

Jeff King 3d8314f8d1 clone: propagate empty remote HEAD even with other branches
Unless "--branch" was given, clone generally tries to match the local
HEAD to the remote one. For most repositories, this is easy: the remote
tells us which branch HEAD was pointing to, and we call our local
checkout() function on that branch.

When cloning an empty repository, it's a little more tricky: we have
special code that checks the transport's "unborn" extension, or falls back
to our local idea of what the default branch should be. In either case,
we point the new HEAD to that, and set up the branch.* config.

But that leaves one case unhandled: when the remote repository _isn't_
empty, but its HEAD is unborn. The checkout() function is smart enough
to realize we didn't fetch the remote HEAD and it bails with a warning.
But we'll have ignored any information the remote gave us via the unborn
extension. This leads to nonsense outcomes:

  - If the remote has its HEAD pointing to an unborn "foo" and contains
    another branch "bar", cloning will get branch "bar" but leave the
    local HEAD pointing at "master" (or whatever our local default is),
    which is useless. The project does not use "master" as a branch.

  - Worse, if the other branch "bar" is instead called "master" (but
    again, the remote HEAD is not pointing to it), then we end up with a
    local unborn branch "master", which is not connected to the remote
    "master" (it shares no history, and there's no branch.* config).

Instead, we should try to use the remote's HEAD, even if its unborn, to
be consistent with the other cases.

The reason this case was missed is that cmd_clone() handles empty and
non-empty repositories on two different sides of a conditional:

  if (we have any refs) {
      fetch refs;
      check for --branch;
      otherwise, try to point our head at remote head;
      otherwise, our head is NULL;
  } else {
      check for --branch;
      otherwise, try to use "unborn" extension;
      otherwise, fall back to our default name name;
  }

So the smallest change would be to repeat the "unborn" logic at the end
of the first block. But we can note some other overlaps and
inconsistencies:

  - both sides have to handle --branch (though note that it's always an
    error for the empty repo case, since an empty repo by definition
    does not have a matching branch)

  - the fall back to the default name is much more explicit in the
    empty-repo case. The non-empty case eventually ends up bailing
    from checkout() with a warning, which produces a similar result, but
    fails to set up the branch config we do in the empty case.

So let's pull the HEAD setup out of this conditional entirely. This
de-duplicates some of the code and the result is easy to follow, because
helper functions like find_ref_by_name() do the right thing even in the
empty-repo case (i.e., by returning NULL).

There are two subtleties:

  - for a remote with a detached HEAD, it will advertise an oid for HEAD
    (which we store in our "remote_head" variable), but we won't find a
    matching refname (so our "remote_head_points_at" is NULL). In this
    case we make a local detached HEAD to match. Right now this happens
    implicitly by reaching update_head() with a non-NULL remote_head
    (since we skip all of the unborn-fallback). We'll now need to
    account for it explicitly before doing the fallback.

  - for an empty repo, we issue a warning to the user that they've
    cloned an empty repo. The text of that warning doesn't make sense
    for a non-empty repo with an unborn HEAD, so we'll have to
    differentiate the two cases there. We could just use different text,
    but instead let's allow the code to continue down to checkout(),
    which will issue an appropriate warning, like:

      remote HEAD refers to nonexistent ref, unable to checkout

    Continuing down to checkout() will make it easier to do more fixes
    on top (see below).

Note that this patch fixes the case where the other side reports an
unborn head to us using the protocol extension. It _doesn't_ fix the
case where the other side doesn't tell us, we locally guess "master",
and the other side happens to have a "master" which its HEAD doesn't
point. But it doesn't make anything worse there, and it should actually
make it easier to fix that problem on top.

Richard Oliver 817b0f6027 mktree: do not check type of remote objects
With 31c8221a (mktree: validate entry type in input, 2009-05-14), we
called the sha1_object_info() API to obtain the type information, but
allowed the call to silently fail when the object was missing locally,
so that we can sanity-check the types opportunistically when the
object did exist.

The implementation is understandable because back then there was no
lazy/on-demand downloading of individual objects from the promisor
remotes that causes a long delay and materializes the object, hence
defeating the point of using "--missing".  The design is hurting us
now.

We could bypass the opportunistic type/mode consistency check
altogether when "--missing" is given, but instead, use the
oid_object_info_extended() API and tell it that we are only interested
in objects that locally exist and are immediately available by passing
OBJECT_INFO_SKIP_FETCH_OBJECT bit to it.  That way, we will still
retain the cheap and opportunistic sanity check for local objects.

Jiang Xin b4eda05d58 i18n: fix mismatched camelCase config variables
Some config variables are combinations of multiple words, and we
typically write them in camelCase forms in manpage and translatable
strings. It's not easy to find mismatches for these camelCase config
variables during code reviews, but occasionally they are identified
during localization translations.

To check for mismatched config variables, I introduced a new feature
in the helper program for localization[^1]. The following mismatched
config variables have been identified by running the helper program,
such as "git-po-helper check-pot".

Lowercase in manpage should use camelCase:

 * Documentation/config/http.txt: http.pinnedpubkey

Lowercase in translable strings should use camelCase:

 * builtin/fast-import.c:  pack.indexversion
 * builtin/gc.c:           gc.logexpiry
 * builtin/index-pack.c:   pack.indexversion
 * builtin/pack-objects.c: pack.indexversion
 * builtin/repack.c:       pack.writebitmaps
 * commit.c:               i18n.commitencoding
 * gpg-interface.c:        user.signingkey
 * http.c:                 http.postbuffer
 * submodule-config.c:     submodule.fetchjobs

Mismatched camelCases, choose the former:

 * Documentation/config/transfer.txt: transfer.credentialsInUrl
   remote.c:                          transfer.credentialsInURL

Johannes Schindelin 41a86b64c0 submodule--helper: avoid memory leak when fetching submodules
In c51f8f94e5 (submodule--helper: run update procedures from C,
2021-08-24), we added code that first obtains the default remote, and
then adds that to a `strvec`.

However, we never released the default remote's memory.

Reported by Coverity.

Junio C Hamano 5a5ea141e7 revision: mark blobs needed for resolve-undo as reachable
The resolve-undo extension was added to the index in cfc5789a
(resolve-undo: record resolved conflicts in a new index extension
section, 2009-12-25).  This extension records the blob object names
and their modes of conflicted paths when the path gets resolved
(e.g. with "git add"), to allow "undoing" the resolution with
"checkout -m path".  These blob objects should be guarded from
garbage-collection while we have the resolve-undo information in the
index (otherwise unresolve operation may try to use a blob object
that has already been pruned away).

But the code called from mark_reachable_objects() for the index
forgets to do so.  Teach add_index_objects_to_pending() helper to
also add objects referred to by the resolve-undo extension.

Also make matching changes to "fsck", which has code that is fairly
similar to the reachability stuff, but have parallel implementations
for all these stuff, which may (or may not) someday want to be unified.
