This reverts commit 6436a20284f33d42103cac93bd82e65bebb31526.
The idea of that commit is that if read_ref_at() is counting back to the
Nth reflog but the reflog is short by one entry (e.g., because it was
pruned), we can find the oid of the missing entry by looking at the
"before" oid value of the entry that comes after it (whereas before, we
looked at the "after" value of each entry and complained that we
couldn't find the one from before the truncation).
This works fine for resolving the oid of ref@{n}, as it is used by
get_oid_basic(), which does not look at any other aspect of the reflog
we found (e.g., its timestamp or message). But there's another caller of
read_ref_at(): in show-branch we use it to walk over the reflog, and we
do care about the reflog entry. And so that commit broke "show-branch
--reflog"; it shows the reflog message for ref@{0} as ref@{1}, ref@{1}
as ref@{2}, and so on.
For example, in the new test in t3202 we produce:
! [branch@{0}] (0 seconds ago) commit: three
! [branch@{1}] (0 seconds ago) commit: three
! [branch@{2}] (60 seconds ago) commit: two
! [branch@{3}] (2 minutes ago) reset: moving to HEAD^
instead of the correct:
! [branch@{0}] (0 seconds ago) commit: three
! [branch@{1}] (60 seconds ago) commit: two
! [branch@{2}] (2 minutes ago) reset: moving to HEAD^
! [branch@{3}] (2 minutes ago) commit: one
But there's another bug, too: because it is looking at the "old" value
of the reflog after the one we're interested in, it has to special-case
ref@{0} (since there isn't anything after it). That's why it doesn't
show the offset bug in the output above. But this special-case code
fails to handle the situation where the reflog is empty or missing; it
returns success even though the reflog message out-parameter has been
left uninitialized. You can't trigger this through get_oid_basic(), but
"show-branch --reflog" will pretty reliably segfault as it tries to
access the garbage pointer.
Fixing the segfault would be pretty easy. But the off-by-one problem is
inherent in this approach. So let's start by reverting the commit to
give us a clean slate to work with.
This isn't a pure revert; all of the code changes are reverted, but for
the tests:
1. We'll flip the cases in t1508 to expect_failure; making these work
was the goal of 6436a2028, and we'll want to use them for our
replacement approach.
2. There's a test in t3202 for "show-branch --reflog", but it expects
the broken output! It was added by f2463490c4 (show-branch: show
reflog message, 2021-12-02) which was fixing another bug, and I
think the author simply didn't notice that the second line showed
the wrong reflog.
Rather than fixing that test, let's replace it with one that is
more thorough (while still covering the reflog message fix from
that commit). We'll use a longer reflog, which lets us see more
entries (thus making the "off by one" pattern much more clear). And
we'll use a more recent timestamp for "now" so that our relative
dates have more resolution. That lets us see that the reflog dates
are correct (whereas when you are 4 years away, two entries that
are 60 seconds apart will have the same "4 years ago" relative
date). Because we're adjusting the repository state, I've moved
this new test to the end of the script, leaving the other tests
undisturbed.
We'll also add a new test which covers the missing reflog case;
previously it segfaulted, but now it reports the empty reflog).

Since 583b7ea31b (upload-pack/fetch-pack: support side-band
communication, 2006-06-21) the abort message sent by upload-pack in
case of possible repository corruption ends with a null character.
This can be seen in several test cases in 't5530-upload-pack-error.sh'
where 'grep <pattern> output.err' often reports "Binary file
output.err matches" because of that null character.
The reason for this is that the abort message is defined as a string
literal, and we pass its size to the send function as
sizeof(abort_msg), which also counts the terminating null character.
Use strlen() instead to avoid sending that terminating null character.

The textconv caching system uses git-notes to store its cache entries.
But if you're using "diff --no-index" outside of a repository, then
obviously that isn't going to work.
Since caching is just an optimization, it's OK for us to skip it.
However, the current behavior is much worse: we call notes_cache_init()
which tries to look up the ref, and the low-level ref code hits a BUG(),
killing the program. Instead, we should notice before setting up the
cache that it there's no repository, and just silently skip it.

1c56fc2084 (name-rev: pre-size buffer in get_parent_name(), 2020-02-04)
got a big performance boost in an unusual repository by calculating the
name length in advance. This is a bit awkward, as it references the
name components twice.
Use a memory pool to store the strings for the struct rev_name member
tip_name. Using mem_pool_strfmt() allows efficient allocation without
explicit size calculation. This simplifies the formatting part of the
code without giving up performance:
Benchmark 1: ./git_2.44.0 -C ../chromium/src name-rev --all
Time (mean ± σ): 1.231 s ± 0.013 s [User: 1.082 s, System: 0.136 s]
Range (min … max): 1.214 s … 1.252 s 10 runs
Benchmark 2: ./git -C ../chromium/src name-rev --all
Time (mean ± σ): 1.220 s ± 0.020 s [User: 1.083 s, System: 0.130 s]
Range (min … max): 1.197 s … 1.254 s 10 runs
Don't bother discarding the memory pool just before exiting. The effort
for that would be very low, but actually measurable in the above
example, with no benefit to users. At least UNLEAK it to calm down leak
checkers. This addresses the leaks that 45a14f578e (Revert "name-rev:
release unused name strings", 2022-04-22) brought back.

Add a function for building a string, printf style, using a memory pool.
It uses the free space in the current block in the first attempt. If
that suffices then the result can already be used without copying or
reformatting.
For strings that are significantly shorter on average than the block
size (ca. 1 MiB by default) this is the case most of the time, leading
to a better perfomance than a solution that doesn't access mem-pool
internals.

Introduce a new ref iteration flag `DO_FOR_EACH_INCLUDE_ROOT_REFS`,
which will be used to iterate over regular refs plus pseudorefs and
HEAD.
Refs which fall outside the `refs/` and aren't either pseudorefs or HEAD
are more of a grey area. This is because we don't block the users from
creating such refs but they are not officially supported.
Introduce `refs_for_each_include_root_refs()` which calls
`do_for_each_ref()` with this newly introduced flag.
In `refs/files-backend.c`, introduce a new function
`add_pseudoref_and_head_entries()` to add pseudorefs and HEAD to the
`ref_dir`. We then finally call `add_pseudoref_and_head_entries()`
whenever the `DO_FOR_EACH_INCLUDE_ROOT_REFS` flag is set. Any new ref
backend will also have to implement similar changes on its end.

Introduce two new functions `is_pseudoref()` and `is_headref()`. This
provides the necessary functionality for us to add pseudorefs and HEAD
to the loose ref cache in the files backend, allowing us to build
tooling to print these refs.
The `is_pseudoref()` function internally calls `is_pseudoref_syntax()`
but adds onto it by also checking to ensure that the pseudoref either
ends with a "_HEAD" suffix or matches a list of exceptions. After which
we also parse the contents of the pseudoref to ensure that it conforms
to the ref format.
We cannot directly add the new syntax checks to `is_pseudoref_syntax()`
because the function is also used by `is_current_worktree_ref()` and
making it stricter to match only known pseudorefs might have unintended
consequences due to files like 'BISECT_START' which isn't a pseudoref
but sometimes contains object ID.
Keeping this in mind, we leave `is_pseudoref_syntax()` as is and create
`is_pseudoref()` which is stricter. Ideally we'd want to move the new
syntax checks to `is_pseudoref_syntax()` but a prerequisite for this
would be to actually remove the exception list by converting those
pseudorefs to also contain a '_HEAD' suffix and perhaps move bisect
related files like 'BISECT_START' to a new directory similar to the
'rebase-merge' directory.

There is an error message in that function to report a missing tree; In
contrast to three other, similar error messages, it is not marked for
translation yet.
Mark it for translation, and while at it, make the error message
consistent with the others by enclosing the SHA in parentheses.
This requires a change to t6030 which expects the previous format of the
commit message. Theoretically, this could present problems with existing
scripts that use `git bisect` and parse its output (because Git does not
provide other means for callers to discern between error conditions).
However, this is unlikely to matter in practice because the most common
course of action to deal with fatal corruptions is to report the error
message to the user and exit, rather than trying to do something with
the reported SHA of the missing tree.

The first thing the `parse_tree()` function does is to return early if
the tree has already been parsed. Therefore we do not need to guard the
`parse_tree()` call behind a check of that flag.
As of time of writing, there are no other instances of this in Git's
code bases: whenever the `parsed` flag guards a `parse_tree()` call, it
guards more than just that call.

Otherwise we may easily run into serious crashes: For example, if we run
`init_tree_desc()` directly after a failed `parse_tree()`, we are
accessing uninitialized data or trying to dereference `NULL`.
Note that the `parse_tree()` function already takes care of showing an
error message. The `parse_tree_indirectly()` and
`repo_get_commit_tree()` functions do not, therefore those latter call
sites need to show a useful error message while the former do not.

not treated as an error.
This patch addresses the same issue for the remaining two callers of
`parse_tree()`.
This change is not accompanied by a regression test because the code in
question is only reached at the `checkout` stage, i.e. after the merge
has happened (and therefore the tree objects could only be missing if
the disk had gone bad in that short time window, or something similarly
tricky to recreate in the test suite).

While the git-reflog(1) command has subcommands to show reflog entries
or check for reflog existence, it does not have any subcommands that
would allow the user to enumerate all existing reflogs. This makes it
quite hard to discover which reflogs a repository has. While this can
be worked around with the "files" backend by enumerating files in the
".git/logs" directory, users of the "reftable" backend don't enjoy such
a luxury.
Introduce a new subcommand `git reflog list` that lists all reflogs the
repository knows of to fill this gap.

The reflog iterator tries to resolve the corresponding ref for every
reflog that it is about to yield. Historically, this was done due to
multiple reasons:
- It ensures that the refname is safe because we end up calling
`check_refname_format()`. Also, non-conformant refnames are skipped
altogether.
- The iterator used to yield the resolved object ID as well as its
flags to the callback. This info was never used though, and the
corresponding parameters were dropped in the preceding commit.
- When a ref is corrupt then the reflog is not emitted at all.
We're about to introduce a new `git reflog list` subcommand that will
print all reflogs that the refdb knows about. Skipping over reflogs
whose refs are corrupted would be quite counterproductive in this case
as the user would have no way to learn about reflogs which may still
exist in their repository to help and rescue such a corrupted ref. Thus,
the only remaining reason for why we'd want to resolve the ref is to
verify its refname.
Refactor the code to call `check_refname_format()` directly instead of
trying to resolve the ref. This is significantly more efficient given
that we don't have to hit the object database anymore to list reflogs.
And second, it ensures that we end up showing reflogs of broken refs,
which will help to make the reflog more useful.
Note that this really only impacts the case where the corresponding ref
is corrupt. Reflogs for nonexistent refs would have been returned to the
caller beforehand already as we did not pass `RESOLVE_REF_READING` to
the function, and thus `refs_resolve_ref_unsafe()` would have returned
successfully in that case.

The ref and reflog iterators share much of the same underlying code to
iterate over the corresponding entries. This results in some weird code
because the reflog iterator also exposes an object ID as well as a flag
to the callback function. Neither of these fields do refer to the reflog
though -- they refer to the corresponding ref with the same name. This
is quite misleading. In practice at least the object ID cannot really be
implemented in any other way as a reflog does not have a specific object
ID in the first place. This is further stressed by the fact that none of
the callbacks except for our test helper make use of these fields.
Split up the infrastucture so that ref and reflog iterators use separate
callback signatures. This allows us to drop the nonsensical fields from
the reflog iterator.
Note that internally, the backends still use the same shared infra to
iterate over both types. As the backends should never end up being
called directly anyway, this is not much of a problem and thus kept
as-is for simplicity's sake.

When iterating through reflogs in a worktree we create a merged iterator
that merges reflogs from both refdbs. The resulting refs are ordered so
that instead we first return all worktree reflogs before we return all
common refs.
This is the only remaining case where a ref iterator returns entries in
a non-lexicographic order. The result would look something like the
following (listed with a command we introduce in a subsequent commit):
```
$ git reflog list
HEAD
refs/worktree/per-worktree
refs/heads/main
refs/heads/wt
```
So we first print the per-worktree reflogs in lexicographic order, then
the common reflogs in lexicographic order. This is confusing and not
consistent with how we print per-worktree refs, which are exclusively
sorted lexicographically.
Sort reflogs lexicographically in the same way as we sort normal refs.
As this is already implemented properly by the "reftable" backend via a
separate selection function, we simply pull out that logic and reuse it
for the "files" backend. As logs are properly sorted now, mark the
merged reflog iterator as sorted.
Tests will be added in a subsequent commit.

The `struct dir_iterator` is a helper that allows us to iterate through
directory entries. This iterator returns entries in the exact same order
as readdir(3P) does -- or in other words, it guarantees no specific
order at all.
This is about to become problematic as we are introducing a new reflog
subcommand to list reflogs. As the "files" backend uses the directory
iterator to enumerate reflogs, returning reflog names and exposing them
to the user would inherit the indeterministic ordering. Naturally, it
would make for a terrible user interface to show a list with no
discernible order.
While this could be handled at a higher level by the new subcommand
itself by collecting and ordering the reflogs, this would be inefficient
because we would first have to collect all reflogs before we can sort
them, which would introduce additional latency when there are many
reflogs.
Instead, introduce a new option into the directory iterator that asks
for its entries to be yielded in lexicographical order. If set, the
iterator will read all directory entries greedily and sort them before
we start to iterate over them.
While this will of course also incur overhead as we cannot yield the
directory entries immediately, it should at least be more efficient than
having to sort the complete list of reflogs as we only need to sort one
directory at a time.
This functionality will be used in a follow-up commit.

Correct a few random "sendemail.*" configuration parameter names in the
documentation that, for some unknown reason and contrary to the expected,
didn't use camel case format.
The majority of the corrections are straightforward, by using camel case
to denote boundaries of the individual words that, stringed together, make
up configuration parameter names. A couple of abbreviations found in some
of the corrected configuration parameter names present some exceptions,
which are described in detail below.
First, there's "SSL" as the abbreviation for "Secure Sockets Layer". [1]
As such, it's written using all uppercase letters, which is pretty much the
general rule for making abbreviations, although with certain exceptions.
Second, there's "Cc" as the abbreviation for "carbon copy", which is another
exception. As the acronym for "carbon copy", "cc" (mind the all lowercase
letters) stems from the rather old times when, literally, carbon copies were
made. [2] Therefore, using "CC" (mind the all uppercase letters) or "cc"
(mind the all lowercase letters) would be technically correct in the email
domain, as the abbreviation or as mentioned in RFC2076, [3] respectively, but
the age of email has established "Cc" (mind the mixed uppercase and lowercase
letters) as some kind of de facto standard. [1][4][5] Moreover, some of the
git utilities, primarily git-send-email(1), already refer to making email
carbon copies as specifying "Cc:" email headers. As a result, "Cc" becomes
one of the exceptions to the general rule for making abbreviations.

The `--trust-exit-code` option for git-diff-tool(1) was introduced via
2b52123fcf (difftool: add support for --trust-exit-code, 2014-10-26).
When set, it makes us return the exit code of the invoked diff tool when
diffing multiple files. This patch didn't change the code path where
`--dir-diff` was passed because we already returned the exit code of the
diff tool unconditionally in that case.
This was changed a month later via c41d3fedd8 (difftool--helper: add

added to the end of git-difftool--helper.sh. While the stated intent of
that commit was merely a cleanup, it had the consequence that we now

change in behaviour is thus very likely an unintended side effect of
this patch.
Now there are two ways to fix this:
- We can either restore the original behaviour, which unconditionally
returned the exit code of the diffing tool when `--dir-diff` is
passed.
- Or we can make the `--dir-diff` case respect the `--trust-exit-code`
flag.
The fact that we have been ignoring exit codes for 7 years by now makes
me rather lean towards the latter option. Furthermore, respecting the
flag in one case but not the other would needlessly make the user
interface more complex.
Fix the bug so that we also honor `--trust-exit-code` for dir diffs and
adjust the documentation accordingly.

Fix to an already-graduated topic.
* la/trailer-cleanups:
trailer: fix comment/cut-line regression with opts->no_divider
|
|
Commit 97e9d0b78a (trailer: find the end of the log message, 2023-10-20)
combined two code paths for finding the end of the log message. For the
"no_divider" case, we used to use find_trailer_end(), and that has now
been rolled into find_end_of_log_message(). But there's a regression;
that function returns early when no_divider is set, returning the whole
string.
That's not how find_trailer_end() behaved. Although it did skip the
"---" processing (which is what "no_divider" is meant to do), we should
still respect ignored_log_message_bytes(), which covers things like
comments, "commit -v" cut lines, and so on.
The bug is actually in the interpret-trailers command, but the obvious
way to experience it is by running "commit -v" with a "--trailer"
option. The new trailer will be added at the end of the verbose diff,
rather than before it (and consequently will be ignored entirely, since
everything after the diff's intro scissors line is thrown away).
I've added two tests here: one for interpret-trailers directly, which
shows the bug via the parsing routines, and one for "commit -v".
The fix itself is pretty simple: instead of returning early, no_divider
just skips the "---" handling but still calls ignored_log_message_bytes().

The Perl implementation of add --interactive was removed in commit [1].
Additionally, the interactive.singleKey setting is no longer silently
ignored. The internal implementation of ReadKey [2] displays a warning
if the platform is unsupported.

Our lib-credential.sh library comes with a "clean" function that removes
all of the credentials used in its tests (to avoid leaving cruft in
system credential storage). But it's easy to add a test that uses a new
credential but forget to add it to the clean function. E.g., the case
fixed by 83e6eb7d7a (t/lib-credential: clean additional credential,
2024-02-15).
We should be able to catch this automatically, but it's a little tricky.
We can't just compare the contents of the helper's storage before and
after the test run, because there isn't a way to ask a helper to dump
all of its storage. And in most cases we don't have direct access to the
underlying storage (since the whole point of the helper is to abstract
that away). We can work around that by using our own "store" helper,
since we can directly inspect its state by looking at its on-disk file.
But there's a catch: the "store" helper doesn't support features like
caching or expiration, so using it naively fails tests (and skipping
those tests would give us incomplete coverage). Implementing all of
those features would be non-trivial. But we can hack around that by
overriding the "check" function used by the tests to turn most requests
into noop success (except for "approve" requests, which actually store
things).
And then at the end we can check that running the "clean" function takes
us back to an empty state.
Note that because we've skipped any tests that erase credentials
(because of our noop check function), the state we see at cleanup time
may be larger than it would be normally. That's OK. The point of the
clean function is to clean up any cruft we _might_ have left in place,
so we're just being doubly thorough.
The way this is bolted onto t0303 feels a little messy. But it's really
the best place to do it, because then we know that it is running the
exact sequence of tests that we'd use for testing a real external
helper. In a normal run of "make test" it currently does nothing (the
idea is that you run it manually after pointing it at some helper
program). But now with this patch, "make test" will sanity-check the
script itself.

The /mergetools/vimdiff script, which handles both vimdiff, nvimdiff
and gvimdiff mergetools (the latter 2 simply source the vimdiff script), has a
function merge_cmd() which read the layout variable from git config, and it
would always read the value of mergetool.**vimdiff**.layout, instead of the
mergetool being currently used (vimdiff or nvimdiff or gvimdiff).
It looks like in 7b5cf8be18 (vimdiff: add tool documentation, 2022-03-30),
we explained the current behavior in Documentation/config/mergetool.txt:
```
mergetool.vimdiff.layout::
The vimdiff backend uses this variable to control how its split
windows look like. Applies even if you are using Neovim (`nvim`) or
gVim (`gvim`) as the merge tool. See BACKEND SPECIFIC HINTS section
```
which makes sense why it's explained this way - the vimdiff backend is used by
gvim and nvim. But the mergetool's configuration should be separate for each tool,
and indeed that's confirmed in same commit at Documentation/mergetools/vimdiff.txt:
```
Variants
Instead of `--tool=vimdiff`, you can also use one of these other variants:
* `--tool=gvimdiff`, to open gVim instead of Vim.
* `--tool=nvimdiff`, to open Neovim instead of Vim.
When using these variants, in order to specify a custom layout you will have to
set configuration variables `mergetool.gvimdiff.layout` and
`mergetool.nvimdiff.layout` instead of `mergetool.vimdiff.layout`
```
So it looks like we just forgot to update the 1 part of the vimdiff script
that read the config variable. Cheers.
Though, for backward compatibility, I've kept the mergetool.vimdiff
fallback, so that people who unknowingly relied on it, won't have their
setup broken now.
