The `struct reftable_reader` subsystem encapsulates a table that has
been read from the disk. As such, the current name of that structure is
somewhat hard to understand as it only talks about the fact that we read
something from disk, without really giving an indicator _what_ that is.

Furthermore, this naming schema doesn't really fit well into how the
other structures are named: `reftable_merged_table`, `reftable_stack`,
`reftable_block` and `reftable_record` are all named after what they
encapsulate.

Rename the subsystem to `reftable_table`, which directly gives a hint
that the data structure is about handling the individual tables part of
the stack.

While this change results in a lot of churn, it prepares for us exposing
the APIs to third-party callers now that the reftable library is a
standalone library that can be linked against by other projects.

The code that implements block sources is distributed across a couple of
files. Consolidate all of it into "reftable/blocksource.c" and its
accompanying header so that it is easier to locate and more self
contained.

While at it, rename some of the functions to have properly scoped names.

Restart points record the location of reftable records that do not use
prefix compression and are used to perform a binary search inside of a
block. These restart points are encoded at the end of a block, between
the record data and the footer of a table.

The block structure contains three different variables related to these
restart points:

  - The block length contains the length of the reftable block up to the
    restart points.

  - The restart count contains the number of restart points contained in
    the block.

  - The restart bytes variable tracks where the restart point data
    begins.

Tracking all three of these variables is unnecessary though as the data
can be derived from one another: the block length without restart points
is the exact same as the offset of the restart count data, which we
already track via the `restart_bytes` data.

Refactor the code so that we track the location of restart bytes not as
a pointer, but instead as an offset. This allows us to trivially get rid
of the `block_len` variable as described above. This avoids having the
confusing `block_len` variable and allows us to do less bookkeeping
overall.

The logic to read blocks from a reftable is scattered across both the
table and the block subsystems. Besides causing somewhat fuzzy
responsibilities, it also means that we have to awkwardly pass around
the ownership of blocks between the subsystems.

Refactor the code so that we stop passing the block when initializing a
reader, but instead by passing in the block source plus the offset at
which we're supposed to read a block. Like this, the ownership of the
block itself doesn't need to get handed over as the block reader is the
one owning the block right from the start.

The `reftable_block` structure associates a byte slice with a block
source. As such it only holds the data of a reftable block without
actually encoding any of the details for how to access that data.

Rename the structure to instead be called `reftable_block_data`. Besides
clarifying that this really only holds data, it also allows us to rename
the `reftable_block_reader` to `reftable_block` in the next commit, as
this is the structure that actually encapsulates access to the reftable
blocks.

Rename the `struct reftable_block_reader::block` member accordingly.

The `block_reader` structure is used to access parsed data of a reftable
block. The structure is currently treated as an internal implementation
detail and not exposed via our public interfaces. The functionality
provided by the structure is useful to external users of the reftable
library though, for example when implementing consistency checks that
need to scan through the blocks manually.

Rename the structure to `reftable_block` now that the name has been made
available in the preceding commit. This name is in line with the naming
schema used for other data structures like `reftable_table` in that it
describes the underlying entity that it provides access to.

The new data structure isn't yet exposed via the public interface, which
is left for a subsequent commit.

Throughout the Git codebase we're using the typedeffed version of
`z_stream`, which maps to `struct z_stream_s`. By using a typedef
instead of the struct it becomes somewhat harder to predeclare the
symbol so that headers depending on the struct can do so without having
to pull in "zlib-compat.h".

We don't yet have users that would really care about this: the only
users that declare `z_stream` as a pointer are in "reftable/block.h",
which is a header that is internal to the reftable library. But in the
next step we're going to expose the `struct reftable_block` publicly,
and that struct does contain a pointer to `z_stream`. And as the public
header shouldn't depend on "reftable/system.h", which is an internal
implementation detail, we won't have the typedef for `z_stream` readily
available.

Prepare for this change by using `struct z_stream_s` throughout our code
base. In case zlib-ng is used we use a define to map from `z_stream_s`
to `zng_stream_s`.

Drop the pre-declaration of `struct z_stream` while at it. This struct
does not exist in the first place, and the declaration wasn't needed
because "reftable/block.h" already includes "reftable/basics.h" which
transitively includes "reftable/system.h" and thus "git-zlib.h".

While users of the reftable library wouldn't generally require access to
individual blocks in a reftable table, there are valid usecases where
one may require low-level access to them. One such upcoming usecase in
the Git codebase is to implement consistency checks for the reftable
library where we want to verify each block individually.

Create a public interface for reading blocks. The interface isn't yet
complete and lacks e.g. a way to read individual records from a block.
Such missing functionality will be backfilled in subsequent commits.

Note that this change also requires us to expose `reftable_buf`, which
is used by the `reftable_block_first_key()` function.

The block iterator requires access to a bunch of data from the
underlying `reftable_block` that it is iterating over. This data is
stored by copying over relevant data into a separate set of variables.
This has multiple downsides:

  - We require more storage space than necessary. This is more of a
    theoretical issue as we shouldn't ever have many blocks.

  - We have to perform more bookkeeping, and the variable names are
    inconsistent across the two data structures. This can lead to some
    confusion.

  - The lifetime of the block iterator is tied to the block anyway, but
    we hide that a bit by only storing pointers pointing into the block.

There isn't really any good reason why we rip out parts of the block
instead of storing a pointer to the block itself.

Refactor the code to do so. Despite being simpler, it also allows us to
decouple the lifetime of the block iterator from seeking in a subsequent
commit.

Refactor the block iterators so that initialization and seeking are
different from one another. This makes the iterator trivially reseekable
by storing the pointer to the block at initialization time, which we can
then reuse on every seek.

This refactoring prepares the code for exposing a `reftable_iterator`
interface for blocks in a subsequent commit. Callsites are adjusted
accordingly.

Expose a generic iterator over reftable records and expose it via the
public interface. Together with an upcoming iterator for reftable blocks
contained in a table this will allow users to trivially iterate through
blocks and their respective records individually.

This functionality will be used to implement consistency checks for the
reftable backend, which requires more fine-grained control over how we
read data.

The `reftable_table` interface is an internal implementation detail that

Introduce a new iterator that allows the caller to iterate through all
blocks contained in a table. This gives users more fine-grained control
over how exactly those blocks are being read and exposes information to
callers that was previously inaccessible.

This iterator will be required by a future patch series that adds
consistency checks for the reftable backend. In addition to that though
we will also reimplement `reftable_table_print_blocks()` on top of this
new iterator in a subsequent commit.

The logic to print individual blocks in a table is hosted in the
reftable library. This is only the case due to historical reasons though
because users of the library had no interfaces to read blocks one by
one. Otherwise, printing individual blocks has no place in the reftable
library given that the format will not be generic in the first place.

We have now grown a public interface to iterate through blocks contained
in a table, and thus we can finally move the logic to print them into
the test helper.

Move over the logic and refactor it accordingly. Note that the iterator
also trivially allows us to access index sections, which we previously
didn't print at all. This omission wasn't intentional though, so start
dumping those sections as well so that we can assert that indices are
written as expected.

While git-filter-branch(1) is written as a shell script, the
`--state-branch` feature depends on Perl to save and extract the object
ID mappings. This can lead to subtle breakage though:

  - We execute `perl` directly without respecting the `PERL_PATH`
    configured by the distribution. As such, it may happen that we use
    the wrong version of Perl.

  - We install the script unchanged even if Perl isn't available at all
    on the system, so using `--state-branch` would lead to failure
    altogether in that case.

Fix this by dropping Perl and instead implementing the feature with
shell scripting exclusively.

unconditionally though, regardless of whether or not Perl is even

The "cmd-list.perl" script is used to extract the list of commands part
of a specific category and extracts the description of each command from
its respective manpage. The generated output is then included in git(1)
to list all Git commands.

The script is written in Perl. Refactor it to use shell scripting
exclusively so that we can get rid of the mandatory dependency on Perl
to build our documentation.

The converted script is slower compared to its Perl implementation. But
by being careful and not spawning external commands in `format_one ()`
we can mitigate the performance hit to a reasonable level:

    Benchmark 1: Perl
      Time (mean ± σ):      10.3 ms ±   0.2 ms    [User: 7.0 ms, System: 3.3 ms]
      Range (min … max):    10.0 ms …  11.1 ms    200 runs

    Benchmark 2: Shell
      Time (mean ± σ):      74.4 ms ±   0.4 ms    [User: 48.6 ms, System: 24.7 ms]
      Range (min … max):    73.1 ms …  75.5 ms    200 runs

    Summary
      Perl ran
        7.23 ± 0.13 times faster than Shell

While a sevenfold slowdown is significant, the benefit of not requiring
Perl for a fully-functioning Git installation outweighs waiting a couple
of milliseconds longer during the build process.

Above the declaration of git_work_tree_cfg, we have:

  /* This is set by setup_git_dir_gently() and/or git_default_config() */
  char *git_work_tree_cfg;

It can be verified that there is no function called
'setup_git_dir_gently' by running grep on the codebase:

  $ grep -R setup_git_dir_gently .
  ./environment.c:/* This is set by setup_git_dir_gently() and/or git_default_config() */

The comment, introduced in e90fdc3 (Clean up work-tree handling), is
the only occurrence of the name 'setup_git_dir_gently'.

It probably meant 'setup_git_directory_gently' as that is a name of a
real function in setup.c. Correct it.

A common way to run Git's performance benchmarks on repositories other
than Git's own repository (which is not exactly large when compared to
actually large repositories) is to run them like this:

	GIT_PERF_LARGE_REPO=/path/to/my/large/repo \
	./p1234-*.sh -ivx

Contrary to developers' common expectations, this failed to work when
Git was built with a different `GIT_PERF_LARGE_REPO` value specified at
build time: That build-time option would have been written to the
`GIT-BUILD-OPTIONS` file, which in turn would have been sourced by
`test-lib.sh`, which in turn would have been sourced by `perf-lib.sh`,
which in turn would have been sourced by the perf test script,
_overriding_ the environment variable specified in the way illustrated
above.

Since perf tests are not run as part of the build, this most likely
unintended behavior was not caught and certainly not fixed, as the
`GIT_PERF_*` values would have been empty at build-time.

However, in 4638e88 (Makefile: use common template for
GIT-BUILD-OPTIONS, 2024-12-06), a subtle change of behavior was
introduced: Whereas before, a couple of build-time options (the
`GIT_PERF_*` ones included) were written to `GIT-BUILD-OPTIONS` only
when their values were non-empty. With this commit, they are also
written when they are empty.

The consequence is that above-mentioned way to run the perf tests will
not only fail to pick up the desired `GIT_PERF_*` settings when they
were specified differently while building Git, instead the desired
settings will be only respected when specified _while building_ Git.

Let's work around the original issue, i.e. let `GIT_PERF_*` environment
variables override what is recorded in `GIT-BUILD-OPTIONS`.

Note that this is just the tip of the iceberg, there are a couple of
`GIT_TEST_*` options that may want a similar fix in `test-lib.sh`. Due
to time constraints on my side, this here patch focuses exclusively on
the `GIT_PERF_*` settings.

Our tests for git-p4(1) depend on the p4d(1) and p4(1) executables to
exist. As we require specific versions of those binaries which typically
aren't available on common distributions, we install them manually via
"ci/install-dependencies.sh".

This script will put the binaries into "$CUSTOM_PATH", which gets
defined by "ci/lib.sh" -- if not explicitly overridden, its value will
be set to "$HOME/path". This causes issues though when running our tests
as unprivileged user, as we do both in GitLab CI and GitHub Actions,
because "$HOME" will be different when installing dependencies and when
running the tests. Consequently, the downloaded binaries will not be
found unless "$CUSTOM_PATH" is overridden to a common location.

We already do this for GitLab CI, where it points to "/custom". Let's do
the same for GitHub Actions so that Perforce-based tests are executed
again.

The shell completion scripts in "contrib/completion" are being tested,
but none of our build systems support installing them. This is somewhat
confusing for Meson, where users can explicitly enable building these
scripts via `-Dcontrib=completion`. This option only controlls whether
the completions are built and tested against, where "building" is a bit
of an euphemism for "copying them into the build directory".

Teach both our Makefile and Meson to install our Bash completion script.
For now, this is the only completion script that we're installing given
that Bash completions "just work" with a canonical well-known location
nowadays. Other completion scripts, like for example the one for zsh,
don't have a well-known location and/or require extra steps by the user
to make them available. As such, we skip installing these scripts for
now, but we may do so in the future if we ever figure out a proper way
to do this.

This perf script creates a midx by running "git multi-pack-index write"
with the "--stdin-packs" option. We feed that stdin by running "find" on
.git/objects/pack, using sed to strip off everything but the basename.

But that sed invocation also does something peculiar: it adds a "+" to
the start of each pack name. This causes the multi-pack-index command to
barf. The modified name does not match any pack it knows about, so it
ends up with an empty list of packs to put in the midx. And thus nothing
matches the --preferred-pack option we pass, which causes it die().

The fix is to remove the extra "+" (which also lets us simplify the sed
invocation a bit, as it is now just stripping the leading directories).

But that leaves the mystery of why it was ever there in the first place.
The answer is that an earlier iteration of the patch series had a
concept of "disjoint" packs in the midx. And one of its patches here:

  https://lore.kernel.org/git/c52d7e7b27a9add4f58b8334db4fe4498af1c90f.1701198172.git.me@ttaylorr.com/

taught read_packs_from_stdin() to treat a leading "+" as marking a
disjoint pack. But in the second version of the series, which was
ultimately merged, that disjoint concept went away, and the code to
parse "+" did likewise. The regular regression tests were adjusted to
match, but this case in t/perf was forgotten.

When using the launchctl scheduler, the weekly job runs daily, and the
daily job runs on the first six days of each month. This appears to be
due to specifying "Day" in the calendar intervals, which according to
launchd.plist(5) is for specifying days of the month rather than days of
the week. The behaviour of running a job on the 0th day is undocumented,
but in my testing appears to be the same as not specifying "Day" in the
calendar interval, in which case the job will run daily.

Use "Weekday" in the calendar intervals, which is the correct way to
schedule jobs to run on specific days of the week.
