88682b016d protocol-caps.c: fix memory leak in send_info()
Fix a memory leak in a2ba162cda (object-info: support for retrieving
object info, 2021-04-20) which appears to have been based on a
misunderstanding of how the pkt-line.c API works. There is no need to
strdup() input to packet_writer_write(), it's just a printf()-like
format function.

This fixes a potentially large memory leak, since the number of OID
lines the "object-info" call can be arbitrarily large (or a small one
if the request is small).

This makes t5701-git-serve.sh pass again under SANITIZE=leak, as it
did before a2ba162cda.

e082113484 send-email: avoid incorrect header propagation
If multiple independent patches are sent with send-email, even if the
"In-Reply-To" and "References" headers are not managed by --thread or
--in-reply-to, their values may be propagated from prior patches to
subsequent patches with no such headers defined.

To mitigate this and potential future issues, make sure all global
patch-specific variables are always either handled by
command-specific code (e.g. threading), or are reset to their default
values for every iteration.

614c3d8f2e test-lib: set GIT_CEILING_DIRECTORIES to protect the surrounding repository
Every once in a while a test somehow manages to escape from its trash
directory and modifies the surrounding repository, whether because of
a bug in git itself, a bug in a test [1], or e.g. when trying to run
tests with a shell that is, in general, unable to run our tests [2].

Set GIT_CEILING_DIRECTORIES="$TRASH_DIRECTORY/.." as an additional
safety measure to protect the surrounding repository at least from
modifications by git commands executed in the tests (assuming that
handling of ceiling directories during repository discovery is not
broken, and, of course, it won't save us from regular shell commands,
e.g. 'cd .. && rm -f ...').

[1] e.g. https://public-inbox.org/git/20210423051255.GD2947267@szeder.dev
[2] $ git symbolic-ref HEAD
    refs/heads/master
    $ ksh ./t2011-checkout-invalid-head.sh
    [... a lot of "not ok" ...]
    $ git symbolic-ref HEAD
    refs/heads/other

    (In short: 'ksh' doesn't support the 'local' builtin command,
    which is used by 'test_oid', causing it to return with error
    whenever it's called, leaving ZERO_OID set to empty, so when the
    test 'checkout main from invalid HEAD' runs 'echo $ZERO_OID
    >.git/HEAD' it writes a corrupt (not invalid) HEAD, and subsequent
    git commands don't recognize the repository in the trash directory
    anymore, but operate on the surrounding repo.)

d9e9b44d7a sparse-index: copy dir_hash in ensure_full_index()
Copy the 'index_state->dir_hash' back to the real istate after expanding
a sparse index.

A crash was observed in 'git status' during some hashmap lookups with
corrupted hashmap entries.  During an index expansion, new cache-entries
are added to the 'index_state->name_hash' and the 'dir_hash' in a
temporary 'index_state' variable 'full'.  However, only the 'name_hash'
hashmap from this temp variable was copied back into the real 'istate'
variable.  The original copy of the 'dir_hash' was incorrectly
preserved.  If the table in the 'full->dir_hash' hashmap were realloced,
the stale version (in 'istate') would be corrupted.

The test suite does not operate on index sizes sufficiently large to
trigger this reallocation, so they do not cover this behavior.
Increasing the test suite to cover such scale is fragile and likely
wasteful.

597a977489 branch: allow deleting dangling branches with --force
git branch only allows deleting branches that point to valid commits.
Skip that check if --force is given, as the caller is indicating with
it that they know what they are doing and accept the consequences.
This allows deleting dangling branches, which previously had to be
reset to a valid start-point using --force first.

1e93770888 docs: use "character encoding" to refer to commit-object encoding
The word "encoding" can mean a lot of things (e.g., base64 or
quoted-printable encoding in emails, HTML entities, URL encoding, and so
on). The documentation for i18n.commitEncoding and i18n.logOutputEncoding
uses the phrase "character encoding" to make this more clear.

Let's use that phrase in other places to make it clear what kind of
encoding we are talking about. This patch covers the gui.encoding
option, as well as the --encoding option for git-log, etc (in this
latter case, I word-smithed the sentence a little at the same time).
That, coupled with the mention of iconv in the --encoding description,
should make this more clear.

The other spot I looked at is the working-tree-encoding section of
gitattributes(5). But it gives specific examples of encodings that I
think make the meaning pretty clear already.

fd680bc558 logmsg_reencode(): warn when iconv() fails
If the user asks for a pretty-printed commit to be converted (either
explicitly with --encoding=foo, or implicitly because the commit is
non-utf8 and we want to convert it), we pass it through iconv(). If that
fails, we fall back to showing the input verbatim, but don't tell the
user that the output may be bogus.

Let's add a warning to do so, along with a mention in the documentation
for --encoding. Two things to note about the implementation:

  - we could produce the warning closer to the call to iconv() in
    reencode_string_len(), which would let us relay the value of errno.
    But this is not actually very helpful. reencode_string_len() does
    not know we are operating on a commit, and indeed does not know that
    the caller won't produce an error of its own. And the errno values
    from iconv() are seldom helpful (iconv_open() only ever produces
    EINVAL; perhaps EILSEQ from iconv() might be illuminating, but it
    can also return EINVAL for incomplete sequences).

  - if the reason for the failure is that the output charset is not
    supported, then the user will see this warning for every commit we
    try to display. That might be ugly and overwhelming, but on the
    other hand it is making it clear that every one of them has not been
    converted (and the likely outcome anyway is to re-try the command
    with a supported output encoding).

c93ca46cf5 column: fix parsing of the '--nl' option
'git column's '--nl' option can be used to specify a "string to be
printed at the end of each line" (quoting the man page), but this
option and its mandatory argument has been parsed as OPT_INTEGER since
the introduction of the command in 7e29b8254f (Add column layout
skeleton and git-column, 2012-04-21).  Consequently, any non-number
argument is rejected by parse-options, and any number other than 0
leads to segfault:

  $ printf "%s\n" one two |git column --mode=plain --nl=foo
  error: option `nl' expects a numerical value
  $ printf "%s\n" one two |git column --mode=plain --nl=42
  Segmentation fault (core dumped)
  $ printf "%s\n" one two |git column --mode=plain --nl=0

  two

a7439d0f9d xopen: explicitly report creation failures
If the flags O_CREAT and O_EXCL are both given then open(2) is supposed
to create the file and error out if it already exists.  The error
message in that case looks like this:

	fatal: could not open 'foo' for writing: File exists

Without further context this is confusing: Why should the existence of
the file pose a problem?  Isn't that a requirement for writing to it?

Add a more specific error message for that case to tell the user that we
actually don't expect the file to preexist, so the example becomes:

	fatal: unable to create 'foo': File exists

8174627b3d diff-lib: ignore paths that are outside $cwd if --relative asked
For diff family commands, we can tell them to exclude changes outside
of some directories if --relative is requested.

In diff_unmerge(), NULL will be returned if the requested path is
outside of the interesting directories, thus we'll run into NULL
pointer dereference in run_diff_files when trying to dereference
its return value.

Checking for return value of diff_unmerge before dereferencing
is not sufficient, though. Since, diff engine will try to work on such
pathspec later.

Let's not run diff on those unintesting entries, instead.
As a side effect, by skipping like that, we can save some CPU cycles.

597fa8cb43 t6300: don't run cat-file on non-existent object
In t6300, some tests are guarded behind some prerequisites.
Thus, objects created by those tests ain't available if those
prerequisites are unsatistified.  Attempting to run "cat-file"
on those objects will run into failure.

In fact, running t6300 in an environment without gpg(1),
we'll see those warnings:

	fatal: Not a valid object name refs/tags/signed-empty
	fatal: Not a valid object name refs/tags/signed-short
	fatal: Not a valid object name refs/tags/signed-long

Let's put those commands into the real tests, in order to:

* skip their execution if prerequisites aren't satistified.
* check their exit status code

The expected value for objects with type: commit needs to be
computed outside the test because we can't rely on "$3" there.
Furthermore, to prevent the accidental usage of that computed
expected value, BUG out on unknown object's type.

c21b2511c2 t5323: drop mentions of "master"
Commit 0696232390 (pack-redundant: fix crash when one packfile in repo,
2020-12-16) added one some new tests to t5323. At the time, the sub-repo
we used was called "master". But in a parallel branch, this was switched
to "main".

When the latter branch was merged in 27d7c8599b (Merge branch
'js/default-branch-name-tests-final-stretch', 2021-01-25), some of those
spots caused textual conflicts, but some (for tests that were far enough
away from other changed code) were just semantic. The merge resolution
fixed up most spots, but missed this one.

Even though this did impact actual code, it turned out not to fail the
tests. Running 'cd "$master_repo"' ended up staying in the same
directory, running the test in the main trash repo instead of the
sub-repo. But because the point of the test is checking behavior when
there are no packfiles, it worked in either repo (since both are empty
at this point in the script).

a16eb6b1ff maintenance: skip bootout/bootstrap when plist is registered
On macOS, we use launchctl to manage the background maintenance
schedule. This uses a set of .plist files to describe the schedule, but
these files are also registered with 'launchctl bootstrap'. If multiple
'git maintenance start' commands run concurrently, then they can collide
replacing these schedule files and registering them with launchctl.

To avoid extra launchctl commands, do a check for the .plist files on
disk and check if they are registered using 'launchctl list <name>'.
This command will return with exit code 0 if it exists, or exit code 113
if it does not.

We can test this behavior using the GIT_TEST_MAINT_SCHEDULER environment
variable.

baf8ec8d3a rebase -r: don't write .git/MERGE_MSG when fast-forwarding
When fast-forwarding we do not create a new commit so .git/MERGE_MSG
is not removed and can end up seeding the message of a commit made
after the rebase has finished. Avoid writing .git/MERGE_MSG when we
are fast-forwarding by writing the file after the fast-forward
checks. Note that there are no changes to the fast-forward code, it is
simply moved.

Note that the way this change is implemented means we no longer write
the author script when fast-forwarding either. I believe this is safe
for the reasons below but it is a departure from what we do when
fast-forwarding a non-merge commit. If we reword the merge then 'git
commit --amend' will keep the authorship of the commit we're rewording
as it ignores GIT_AUTHOR_* unless --reset-author is passed. It will
also export the correct GIT_AUTHOR_* variables to any hooks and we
already test the authorship of the reworded commit. If we are not
rewording then we no longer call spilt_ident() which means we are no
longer checking the commit author header looks sane. However this is
what we already do when fast-forwarding non-merge commits in
skip_unnecessary_picks() so I don't think we're breaking any promises
by not checking the author here.

2be6b6f411 rebase -r: make 'merge -c' behave like reword
If the user runs git log while rewording a commit it is confusing if
sometimes we're amending the commit that's being reworded and at other
times we're creating a new commit depending on whether we could
fast-forward or not[1]. For this reason the reword command ensures
that there are no uncommitted changes when rewording. The reword
command also allows the user to edit the todo list while the rebase is
paused. As 'merge -c' also rewords commits make it behave like reword
and add a test.

ff7b83f562 completion: tcsh: Fix regression by drop of wrapper functions
The cleanup of old compat wrappers in bash completion caused a
regression on tcsh completion that still uses them.
Let's update the tcsh call site as well for addressing it.

be6444d1ca completion: bash: add correct suffix in variables
__gitcomp automatically adds a suffix, but __gitcomp_nl and others
don't, we need to specify a space by default.

Can be tested with:

  git config branch.autoSetupMe<tab>

This fix only works for versions of bash greater than 4.0, before that
"local sfx" creates an empty string, therefore the unset expansion
doesn't work. The same happens in zsh.

Therefore we don't add the test for that for now.

The correct fix for all shells requires semantic changes in __gitcomp,
but that can be done later.

8bcda98da5 oidtree: avoid unaligned access to crit-bit tree
The flexible array member "k" of struct cb_node is used to store the key
of the crit-bit tree node.  It offers no alignment guarantees -- in fact
the current struct layout puts it one byte after a 4-byte aligned
address, i.e. guaranteed to be misaligned.

oidtree uses a struct object_id as cb_node key.  Since cf0983213c (hash:
add an algo member to struct object_id, 2021-04-26) it requires 4-byte
alignment.  The mismatch is reported by UndefinedBehaviorSanitizer at
runtime like this:

hash.h:277:2: runtime error: member access within misaligned address 0x00015000802d for type 'struct object_id', which requires 4 byte alignment
0x00015000802d: note: pointer points here
 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  00
             ^
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior hash.h:277:2 in

We can fix that by:

1. eliminating the alignment requirement of struct object_id,
2. providing the alignment in struct cb_node, or
3. avoiding the issue by only using memcpy to access "k".

Currently we only store one of two values in "algo" in struct object_id.
We could use a uint8_t for that instead and widen it only once we add
support for our twohundredth algorithm or so.  That would not only avoid
alignment issues, but also reduce the memory requirements for each
instance of struct object_id by ca. 9%.

Supporting keys with alignment requirements might be useful to spread
the use of crit-bit trees.  It can be achieved by using a wider type for
"k" (e.g. uintmax_t), using different types for the members "byte" and
"otherbits" (e.g. uint16_t or uint32_t for each), or by avoiding the use
of flexible arrays like khash.h does.

This patch implements the third option, though, because it has the least
potential for causing side-effects and we're close to the next release.
If one of the other options is implemented later as well to get their
additional benefits we can get rid of the extra copies introduced here.

3cf9bb36bf ci: use upload-artifacts v1 for dockerized jobs
e9f79acb28 (ci: upgrade to using actions/{up,down}load-artifacts v2,
2021-06-23) changed all calls to that action from v1 to v2, but there
is still an open bug[1] that affects all nodejs actions and prevents
its use in 32-bit linux (as used by the Linux32 container)

move all dockerized jobs to use v1 that was built in C# and therefore
doesn't have this problem, which will otherwise manifest with confusing
messages like:

  /usr/bin/docker exec  0285adacc4536b7cd962079c46f85fa05a71e66d7905b5e4b9b1a0e8b305722a sh -c "cat /etc/*release | grep ^ID"
