Now that we've split up the write_sub_test_lib_test*() and
run_sub_test_lib_test*() functions let's fix those tests in
t0000-basic.sh that were verbosely copy/pasting earlier tests.
That we caught all of them was asserted with a follow-up change that's
not part of this series[1], we might add such a duplication check at
some later time, but for now let's just one-off remove the duplicate
boilerplate.

The use of a sub-shell for running the test_cmp of stdout/stderr for
the test author was introduced in this form in 565b6fa87b (tests:
refactor mechanics of testing in a sub test-lib, 2012-12-16), but from
looking at the history that seemed to have diligently copied my
original ad-hoc implementation in 7b90511970 (t/t0000-basic.sh: Run
the passing TODO test inside its own test-lib, 2010-08-19).
There's no reason to use a subshell here, we try to avoid it in
general. It also improves readability, if the test fails we print out
the relative path in the trash directory that needs to be looked
at.
Before that was mostly obscured, since the "write_sub_test_lib_test"
will pick the directory for you from the test name.

barf if it isn't supplied.

Refactor the function to write and run tests of the test-lib.sh output
into two functions.
When this was added back in 565b6fa87b (tests: refactor mechanics of
testing in a sub test-lib, 2012-12-16) there was no reason to do this,
but since we started supporting test arguments in
517cd55fd5 (test-lib: self-test that --verbose works, 2013-06-23)
we've started to write out duplicate tests simply to test different
arguments, now we'll be able to re-use them.
This change doesn't consolidate any of those tests yet, it just makes
it possible to do so. All the changes in t0000-basic.sh are a simple
search-replacement.
Since the _run_sub_test_lib_test_common() function doesn't handle
running the test anymore we can do away with the sub-shell, which was
used to scope an "unset" and "export" shell variables.

Some commands such as "git stash" emit continued options output with
e.g. "git stash -h", because usage_with_options_internal() prefixes
with its own whitespace the resulting output wasn't properly
aligned. Let's account for the added whitespace, which properly aligns
the output.
The "git stash" command has usage output with a N_() translation that
legitimately stretches across multiple lines;
N_("git stash [push [-p|--patch] [-k|--[no-]keep-index] [-q|--quiet]\n"
" [-u|--include-untracked] [-a|--all] [-m|--message <message>]\n"
[...]
We'd like to have that output aligned with the length of the initial
"git stash " output, but since usage_with_options_internal() adds its
own whitespace prefixing we fell short, before this change we'd emit:
$ git stash -h
usage: git stash list [<options>]
or: git stash show [<options>] [<stash>]
[...]
or: git stash [push [-p|--patch] [-k|--[no-]keep-index] [-q|--quiet]
[-u|--include-untracked] [-a|--all] [-m|--message <message>]
[...]
Now we'll properly emit aligned output. I.e. the last four lines
above will instead be (a whitespace-only change to the above):
[...]
or: git stash [push [-p|--patch] [-k|--[no-]keep-index] [-q|--quiet]
[-u|--include-untracked] [-a|--all] [-m|--message <message>]
[...]
We could also go for an approach where we have the caller support no
padding of their own, i.e. (same as the first example, except for the
padding on the second line):
N_("git stash [push [-p|--patch] [-k|--[no-]keep-index] [-q|--quiet]\n"
"[-u|--include-untracked] [-a|--all] [-m|--message <message>]\n"
[...]
But to do that we'll need to find the length of "git stash". We can
discover that from the "cmd" in the "struct cmd_struct", but there
might be cases with sub-commands or "git" itself taking arguments that
would make that non-trivial.
Even if it were I still think this approach is better, because this way
we'll get the same legible alignment in the C code. The fact that
usage_with_options_internal() is adding its own prefix padding is an
implementation detail that callers shouldn't need to worry about.
Implementation notes:
We could skip the string_list_split() with a strchr(str, '\n') check,
but we'd then need to duplicate our state machine for strings that do
and don't contain a "\n". It's simpler to just always split into a
"struct string_list", even though the common case is that that "struct
string_list" will contain only one element. This is not
performance-sensitive code.
This change is relatively more complex since I've accounted for making
it future-proof for RTL translation support. Later in
usage_with_options_internal() we have some existing padding code
dating back to d7a38c54a6 (parse-options: be able to generate usages
automatically, 2007-10-15) which isn't RTL-safe, but that code would
be easy to fix. Let's not introduce new RTL translation problems here.

Change the bitfield added in 58300f4743 (sparse-index: add
index.sparse config option, 2021-03-30) and 3964fc2aae (sparse-index:
add guard to ensure full index, 2021-03-30) to just use an "int"
boolean instead.
It might be smart to optimize the space here in the future, but by
consistently using an "int" we can take its address and pass it to
repo_cfg_bool(), and therefore don't need to handle "sparse_index" as
a special-case when reading the "index.sparse" setting.
There's no corresponding config for "command_requires_full_index", but
let's change it too for consistency and to prevent future bugs
creeping in due to one of these being "unsigned".
Using "int" consistently also prevents subtle bugs or undesired
control flow creeping in here. Before the preceding commit the
initialization of "command_requires_full_index" in
prepare_repo_settings() did nothing, i.e. this:
r->settings.command_requires_full_index = 1
Was redundant to the earlier memset() to -1. Likewise for
"sparse_index" added in 58300f4743 (sparse-index: add index.sparse
config option, 2021-03-30) the code and comment added there was
misleading, we weren't initializing it to off, but re-initializing it
from "1" to "0", and then finally checking the config, and perhaps
setting it to "1" again. I.e. we could have applied this patch before
the preceding commit:
+ assert(r->settings.command_requires_full_index == 1);
r->settings.command_requires_full_index = 1;
/*
* Initialize this as off.
*/
+ assert(r->settings.sparse_index == 1);
r->settings.sparse_index = 0;
if (!repo_config_get_bool(r, "index.sparse", &value) && value)
r->settings.sparse_index = 1;

Simplify the setup code in repo-settings.c in various ways, making the
code shorter, easier to read, and requiring fewer hacks to do the same
thing as it did before:
Since 7211b9e753 (repo-settings: consolidate some config settings,
2019-08-13) we have memset() the whole "settings" structure to -1 in
prepare_repo_settings(), and subsequently relied on the -1 value.
Most of the fields did not need to be initialized to -1, and because
we were doing that we had the enum labels "UNTRACKED_CACHE_UNSET" and
"FETCH_NEGOTIATION_UNSET" purely to reflect the resulting state
created this memset() in prepare_repo_settings(). No other code used
or relied on them, more on that below.
For the rest most of the subsequent "are we -1, then read xyz" can
simply be removed by re-arranging what we read first. E.g. when
setting the "index.version" setting we should have first read
"feature.experimental", so that it (and "feature.manyfiles") can
provide a default for our "index.version".
Instead the code setting it, added when "feature.manyFiles"[1] was
created, was using the UPDATE_DEFAULT_BOOL() macro added in an earlier
commit[2]. That macro is now gone, since it was only needed for this
pattern of reading things in the wrong order.
This also fixes an (admittedly obscure) logic error where we'd
conflate an explicit "-1" value in the config with our own earlier
memset() -1.
We can also remove the UPDATE_DEFAULT_BOOL() wrapper added in
[3]. Using it is redundant to simply using the return value from
repo_config_get_bool(), which is non-zero if the provided key exists
in the config.
Details on edge cases relating to the memset() to -1, continued from
"more on that below" above:
* UNTRACKED_CACHE_KEEP:
In [4] the "unset" and "keep" handling for core.untrackedCache was
consolidated. But it while we understand the "keep" value, we don't
handle it differently than the case of any other unknown value.
So let's retain UNTRACKED_CACHE_KEEP and remove the
UNTRACKED_CACHE_UNSET setting (which was always implicitly
UNTRACKED_CACHE_KEEP before). We don't need to inform any code
after prepare_repo_settings() that the setting was "unset", as far
as anyone else is concerned it's core.untrackedCache=keep. if
"core.untrackedcache" isn't present in the config.
* FETCH_NEGOTIATION_UNSET & FETCH_NEGOTIATION_NONE:
Since these two two enum fields added in [5] don't rely on the
memzero() setting them to "-1" anymore we don't have to provide
them with explicit values.

Instead of the global ignore_untracked_cache_config variable added in
dae6c322fa (test-dump-untracked-cache: don't modify the untracked
cache, 2016-01-27) we can make use of the new facility to set config
via environment variables added in d8d77153ea (config: allow
specifying config entries via envvar pairs, 2021-01-12).
It's arguably a bit hacky to use setenv() and getenv() to pass
messages between the same program, but since the test helpers are not
the main intended audience of repo-settings.c I think it's better than
hardcoding the test-only special-case in prepare_repo_settings().
This uses the xsetenv() wrapper added in the preceding commit, if we
don't set these in the environment we'll fail in
t7063-status-untracked-cache.sh, but let's fail earlier anyway if that
were to happen.
This breaks any parent process that's potentially using the
GIT_CONFIG_* and GIT_CONFIG_PARAMETERS mechanism to pass one-shot
config setting down to a git subprocess, but in this case we don't
care about the general case of such potential parents. This process
neither spawns other "git" processes, nor is it interested in other
configuration. We might want to pick up other test modes here, but
those will be passed via GIT_TEST_* environment variables.

Add fatal wrappers for setenv() and unsetenv(). In d7ac12b25d (Add
set_git_dir() function, 2007-08-01) we started checking its return
value, and since 48988c4d0c (set_git_dir: die when setenv() fails,
2018-03-30) we've had set_git_dir_1() die if we couldn't set it.
Let's provide a wrapper for both, this will be useful in many other
places, a subsequent patch will make another use of xsetenv().
The checking of the return value here is over-eager according to
setenv(3) and POSIX. It's documented as returning just -1 or 0, so
perhaps we should be checking -1 explicitly.
Let's just instead die on any non-zero, if our C library is so broken
as to return something else than -1 on error (and perhaps not set
errno?) the worst we'll do is die with a nonsensical errno value, but
we'll want to die in either case.
Let's make these return "void" instead of "int". As far as I can tell
there's no other x*() wrappers that needed to make the decision of
deviating from the signature in the C library, but since their return
value is only used to indicate errors (so we'd die here), we can catch
unreachable code such as
if (xsetenv(...) < 0)
[...];
I think it would be OK skip the NULL check of the "name" here for the
calls to die_errno(). Almost all of our setenv() callers are taking a
constant string hardcoded in the source as the first argument, and for
the rest we can probably assume they've done the NULL check
themselves. Even if they didn't, modern C libraries are forgiving
about it (e.g. glibc formatting it as "(null)"), on those that aren't,
well, we were about to die anyway. But let's include the check anyway
for good measure.

A rebase started with 'git rebase <A> <B>' is conceptually to first
checkout <B> and run 'git rebase <A>' starting from that state. 'git

the state we checked out <B>.
This used to work, even when <B> is a tag that points at a commit,
until Git 2.20.0 when the command was reimplemented in C. The command
now complains that the tag object itself cannot be checked out, which
may be technically correct but is not what the user asked to do.
Fix this old regression by using lookup_commit_reference_by_name()

Our grep_buffer() function takes a non-const buffer, which is confusing:
we don't take ownership of nor write to the buffer.
This mostly comes from the fact that the underlying grep_source struct
in which we store the buffer uses non-const pointer. The memory pointed
to by the struct is sometimes owned by us (for FILE or OID sources), and
sometimes not (for BUF sources).
Let's store it as const, which lets us err on the side of caution (i.e.,
the compiler will warn us if any of our code writes to or tries to free
it).
As a result, we must annotate the one place where we do free it by
casting away the constness. But that's a small price to pay for the
extra safety and clarity elsewhere (and indeed, it already had a comment
explaining why GREP_SOURCE_BUF _didn't_ free it).
And then we can mark grep_buffer() as taking a const buffer.

When we're grepping in a buffer, we don't need to modify it. So we can
take "const char *" buffers, rather than "char *". This can avoid some
awkward casts in our callers, and make our expectations more clear (we
will not take ownership of the memory, nor will we ever write to it).
These spots don't all necessarily have to be converted at the same time,
but some of them are dependent on others, because we pass
pointers-to-pointers in a few cases. And none of this should change any
behavior, since we're just adding "const" qualifiers (and likewise, the
compiler will let us know if we missed any spots). So it's relatively
low-risk to just do this all at once.

We find the end of each matching line of a buffer, and then temporarily
write a NUL to turn it into a regular C string. But we don't need to do
so, because the only thing we do in the interim is pass the line and its
length (via an "eol" pointer) to match_line(). And that function should
only look at the bytes we passed it, whether it has a terminating NUL or
not.
We can drop this temporary write in order to simplify the code and make
it easier to use const buffers in more of grep.c.

When showing lines via grep (or looking for funcnames), we call
show_line() on a multi-line buffer. It finds the end of line and marks
it with a NUL. However, we don't need to do so, as the resulting line is
only used along with its "eol" marker:
- we pass both to next_match(), which takes care to look at only the
bytes we specified
- we pass the line to output_color() without its matching eol marker.
However, we do use the "match" struct we got from next_match() to
tell it how many bytes to look at (which can never exceed the string
we passed it).
So we can stop setting and restoring this NUL marker. That makes the
code simpler, and will allow us to take a const buffer in a future
patch.

When grepping for headers in commit objects, we receive individual
lines (e.g., "author Name <email> 1234 -0000"), and then strip off the
timestamp to do our match. We do so by writing a NUL byte over the
whitespace separator, and then remembering to restore it later.
We had to do it this way when this was added back in a4d7d2c6db (log
--author/--committer: really match only with name part, 2008-09-04),
because we fed the result directly to regexec(), which expects a
NUL-terminated string. But since b7d36ffca0 (regex: use regexec_buf(),
2016-09-21), we have a function which can match part of a buffer.
So instead of modifying the string, we can instead just move the "eol"
pointer, and the rest of the code will do the right thing. This will let
further patches mark more buffers as "const".

The order in which various files that make up a single (conceptual)
packfile has been reevaluated and straightened up. This matters in
correctness, as an incomplete set of files must not be shown to a
running Git.

pack-objects: rename .idx files into place after .bitmap files
pack-write: split up finish_tmp_packfile() function
builtin/index-pack.c: move `.idx` files into place last
index-pack: refactor renaming in final()
builtin/repack.c: move `.idx` files into place last
pack-write.c: rename `.idx` files after `*.rev`
pack-write: refactor renaming in finish_tmp_packfile()
bulk-checkin.c: store checksum directly
pack.h: line-wrap the definition of finish_tmp_packfile()
Update the build procedure to use the "-pedantic" build when
DEVELOPER makefile macro is in effect.

developer: enable pedantic by default
win32: allow building with pedantic mode enabled

The code to show progress indicator in a few code paths did not
cover between 0-100%, which has been corrected.
* ab/progress-users-adjust-counters:
entry: show finer-grained counter in "Filtering content" progress line
commit-graph: fix bogus counter in "Scanning merged commits" progress line
"git diff --submodule=diff" showed failure from run_command() when
trying to run diff inside a submodule, when the user manually
removes the submodule directory.
* dt/submodule-diff-fixes:
diff --submodule=diff: don't print failure message twice
diff --submodule=diff: do not fail on ever-initialied deleted submodules
t4060: remove unused variable
Reduce number of write(2) system calls while sending the
ref advertisement.

maintenance: add support for systemd timers on Linux
maintenance: `git maintenance run` learned `--scheduler=<scheduler>`
cache.h: Introduce a generic "xdg_config_home_for(…)" function
The tracing of process ancestry information has been enhanced.
* ab/tr2-leaks-and-fixes:
tr2: log N parent process names on Linux
tr2: do compiler enum check in trace2_collect_process_info()
tr2: leave the parent list empty upon failure & don't leak memory
tr2: stop leaking "thread_name" memory
tr2: clarify TRACE2_PROCESS_INFO_EXIT comment under Linux
tr2: remove NEEDSWORK comment for "non-procfs" implementations
The code to make "git grep" recurse into submodules has been
updated to migrate away from the "add submodule's object store as
an alternate object store" mechanism (which is suboptimal).
* jt/grep-wo-submodule-odb-as-alternate:
t7814: show lack of alternate ODB-adding
submodule-config: pass repo upon blob config read
grep: add repository to OID grep sources
grep: allocate subrepos on heap
grep: read submodule entry with explicit repo
grep: typesafe versions of grep_source_init
grep: use submodule-ODB-as-alternate lazy-addition
submodule: lazily add submodule ODBs as alternates
The reachability bitmap file used to be generated only for a single
pack, but now we've learned to generate bitmaps for history that

Optimize code that handles large number of refs in the "git fetch"
code path.
* ps/fetch-optim:
fetch: avoid second connectivity check if we already have all objects
fetch: merge fetching and consuming refs
fetch: refactor fetch refs to be more extendable
fetch-pack: optimize loading of refs via commit graph
connected: refactor iterator to return next object ID directly
fetch: avoid unpacking headers in object existence check
fetch: speed up lookup of want refs via commit-graph
When cloning a repository with an unborn HEAD, we'll set the local HEAD
to match it only if the local repository is non-bare. This is
inconsistent with all other combinations:
remote HEAD | local repo | local HEAD
-----------------------------------------------
points to commit | non-bare | same as remote
points to commit | bare | same as remote
unborn | non-bare | same as remote
unborn | bare | local default
So I don't think this is some clever or subtle behavior, but just a bug
in 4f37d45706 (clone: respect remote unborn HEAD, 2021-02-05). And it's
easy to see how we ended up there. Before that commit, the code to set
up the HEAD for an empty repo was guarded by "if (!option_bare)". That's
because the only thing it did was call install_branch_config(), and we
don't want to do so for a bare repository (unborn HEAD or not).
That commit put the handling of unborn HEADs into the same block, since
those also need to call install_branch_config(). But the unborn case has
an additional side effect of calling create_symref(), and we want that
to happen whether we are bare or not.
This patch just pulls all of the "figure out the default branch" code
out of the "!option_bare" block. Only the actual config installation is
kept there.
Note that this does mean we might allocate "ref" and not use it (if the
remote is empty but did not advertise an unborn HEAD). But that's not
really a big deal since this isn't a hot code path, and it keeps the
code simple. The alternative would be handling unborn_head_target
separately, but that gets confusing since its memory ownership is
tangled up with the "ref" variable.
There's just one new test, for the case we're fixing. The other ones in
the table are handled elsewhere (the unborn non-bare case just above,
and the actually-born cases in t5601, t5606, and t5609, as they do not
require v2's "unborn" protocol extension).
