5dd5c4e345 t/unit-tests: implement clar specific reftable test helper functions
Helper functions defined in `t/unit-tests/lib-reftable.{c,h}` are
required for the reftable-related test files to run. In the current
implementation these functions are designed to conform with our
homegrown unit-testing structure. So in other to convert the reftable
test files, there is need for a clar specific implementation of these
helper functions.

Implement equivalent helper functions in `lib-reftable-clar.{c,h}` to
use clar. These functions conform with the clar testing framework and
become available for all reftable-related test files implemented using
the clar testing framework, which requires them. This will be used by
subsequent commits.

0f1b33815b test-delta: close output descriptor after use
After we write to the output file, the program exits. This naturally
closes the descriptor. But we should do an explicit close for two
reasons:

  1. It's possible to hit an error on close(), which we should detect
     and report via our exit code.

  2. Leaking descriptors is a bad practice in general. Even if it isn't
     meaningful here, it sets a bad example.

It is tempting to write:

  if (write_in_full(fd, ...) < 0 || close(fd) < 0)
        die_errno(...);

But that pattern contains a subtle problem that has resulted in
descriptor leaks before. If write_in_full() fails, we'll short-circuit
and never call close(), leaking the descriptor.

That's not a problem here, since our error path dies instead of
returning up the stack. But since we're trying to set a good example,
let's write it out as two separate conditions. As a bonus, that lets us
produce a slightly more specific error message.

760dd804bb test-delta: use strbufs to hold input files
We want to read the whole contents of two files into memory. If we
switch from raw ptr/len pairs to strbufs, we can use strbuf_read_file()
to shorten the code.

This incidentally fixes two small bugs:

  1. We stat() the files and allocate our buffers based on st.st_size.
     But that is an off_t which may be larger than the size_t we'd use
     to allocate. We should use xsize_t() to do a checked conversion.
     Otherwise integer truncation (on a file >4GB) could cause us to
     under-allocate (though in practice this does not result in a buffer
     overflow because the same truncation happens when read_in_full()
     also takes a size_t).

  2. We get the size from st.st_size, and then try to read_in_full()
     that many bytes. But it may return fewer bytes than expected (if
     the file changed racily and we get an early EOF), leading us to
     read uninitialized bytes in the allocated buffer. We don't notice
     because we only check the value for error, not that we got the
     expected number of bytes.

The strbuf code doesn't run into this, because it just reads to EOF,
expanding the buffer dynamically as necessary. Neither bug is a big deal
for a test helper, but fixing them is a nice bonus on top of simplifying
the code.

bc235a68c8 test-delta: handle errors with die()
This is a short test helper that does all of its work in the main
function. When we encounter an error, we try to clean up memory and
descriptors and then jump to an error return, which exits the program.

We can get the same effect by just calling die(), which means we do not
have to bother with cleaning up. This simplifies the code, and also
removes some inconsistencies where a few code paths forgot to clean up
descriptors (though in practice it was not a big deal since we were
exiting anyway).

In addition to die() and die_errno(), we'll also use a few of our usual
helpers like xopen() and usage() that make things more ergonomic.

This does change the exit code in these cases from 1 to 128, but I
don't think it matters (and arguably is better, as we'd already exit 128
for other errors like xmalloc() failure).

9b2527caa4 CodingGuidelines: document test balloons in flight
Due to portability concerns, we do not blindly say "It is in [[this
standard]], so we will make liberal use of it" for many features,
and use of C99 language features follow this same principle.  When
we contemplate adopting a language feature that we haven't used in
our codebase, we typically first raise a test balloon, which

 - is a piece of code that exercises the language feature we are
   trying to see if it is OK to adopt

 - is in a small section of code that we know everybody who cares
   about having a working Git must be compiling

 - is in a fairly stable part of the code, to allow reverting it
   easily if some platforms do not understand it yet.

After a few years, with no breakage report from the community, we'd
declare that the feature is now safe to use in our codebase.  Before
that, we forbid the use of the language construct except for the
designated test balloon code site.

The CodingGuidelines document lists these selected features that we
already have determined that they are safe, and also those features
that we know some platforms had trouble with.

Let's also start listing ongoing test balloons and expected timeline
for adoption.  Recently phillip proposed to adopt the syntax to
spell a structure literally (i.e. compound literal) with a new test
balloon, which Patrick made redundant by pointing out an existing
one we had already.but without documenting it.  Start the new section
with an entry for that test balloon.

b06408b817 config: fix sign comparison warnings
There are a couple of -Wsign-compare warnings in "config.c":

  - `prepare_include_condition_pattern()` is returns a signed integer,
    where it either returns a negative error code or the index of the
    last dir separator in a path. That index will always be a
    non-negative number, but we cannot just change the return type to a
    `size_t` due to it being re-used as error code. This is fixed by
    splitting up concerns: the return value is only used as error code,
    and the prefix is now returned via an out-pointer. This fixes a sign
    comparison warning when comparing `text.len < prefix`,

  - We treat `struct config_store_data::seen` as signed integer in
    several places even though it's unsigned.

  - There are multiple trivial sign comparison warnings where we use a
    signed loop index to iterate through an unsigned number of items.

Fix all of these issues and drop the `DISABLE_SIGN_COMPARE_WARNINGS`
macro.

08b775864e config: move Git config parsing into "environment.c"
In "config.c" we host both the business logic to read and write config
files as well as the logic to parse specific Git-related variables. On
the one hand this is mixing concerns, but even more importantly it means
that we cannot easily remove the dependency on `the_repository` in our
config parsing logic.

Move the logic into "environment.c". This file is a grab bag of all
kinds of global state already, so it is quite a good fit. Furthermore,
it also hosts most of the global variables that we're parsing the config
values into, making this an even better fit.

Note that there is one hidden change: in `parse_fsync_components()` we
use an `int` to iterate through `ARRAY_SIZE(fsync_component_names)`. But
as -Wsign-compare warnings are enabled in this file this causes a
compiler warning. The issue is fixed by using a `size_t` instead.

This change allows us to drop the `USE_THE_REPOSITORY_VARIABLE`
declaration.

In 036876a1067 (config: hide functions using `the_repository` by
default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.

Follow through with that intent and remove `git_config_get()`. All
callsites are adjusted so that they use `repo_config_get(the_repository,
...)` instead. While some callsites might already have a repository
available, this mechanical conversion is the exact same as the current
situation and thus cannot cause any regression. Those sites should
eventually be cleaned up in a later patch series.

26552cb62a reflog: close leak of reflog expire entry
find_cfg_ent() allocates a struct reflog_expire_entry_option via
FLEX_ALLOC_MEM and inserts it into a linked list in the
reflog_expire_options structure. The entries in this list are never
freed, resulting in a leak in cmd_reflog_expire and the gc reflog expire
maintenance task:

Direct leak of 39 byte(s) in 1 object(s) allocated from:
    #0 0x7ff975ee6883 in calloc (/lib64/libasan.so.8+0xe6883)

    #15 0x000000444184 in _start (/home/jekeller/libexec/git-core/git+0x444184)

Close this leak by adding a reflog_clear_expire_config() function which
iterates the linked list and frees its elements. Call it upon exit of
cmd_reflog_expire() and reflog_expire_condition().

Add a basic test which covers this leak. While at it, cover the
functionality from commit commit 3cb22b8efe (Per-ref reflog expiry
configuration, 2008-06-15). We've had this support for years, but lacked
any tests.

07714e220b git-gui: do not mix -translation binary and -encoding
git-gui has many instances of '-translation binary' and '-encoding
$SOMETHING' on the same channel.  As eofchar is always null given a
prior commit, the net effect of having '-translation binary' in such
configuration is only to change how text line endings are handled.

For cases where the channel is opened to be consumed via gets, the eol
translation is irrelevant because Tcl's gets is documented to recognize
any of \n, \r, and \r\n as a line ending.  So, keep only the '-encoding
$SOMETHING' configuration in these cases, making the configuration more
clear.

40f54f670a git-gui: replace encoding binary with iso8859-1
git-gui currently configures some channels as '-encoding binary' when
the channel is not really binary (e.g, the channel is consumed as lines
of text).  In 8.6, '-encoding binary' is an alias for '-encoding
iso8859), but TIP 699 removes this alias for Tcl 9.0. Let's switch to
'-encoding iso8859-1' to be compatible across Tcl versions.

f6d3ee2014 git-gui: translation binary defines iso8859-1
git-gui has many cases where -translation binary and -encoding binary
are configured on the same channel. But, -translation binary defines a
binary channel, which sets up -encoding iso8859-1 as part of its work.
Tcl 8.x defines -encoding binary as an alias of -encoding iso8859-1, and
this alias is deleted in Tcl 9.0.  Let's delete the redundant encoding
definition now.

847c8a2ec4 git-gui: assure -eofchar {} on all channels
Per 6eb420ef61 ("git-gui: Always disable the Tcl EOF character when
reading", 2007-07-17), git-gui should disable Tcl's EOF character
detection on all files when on Windows: the default is disabled on all
other platforms (and with Tcl 9.0, is disabled on Windows too).  This
EOF character is for compatibility with files / applications written for
file systems that know only the disc sectors allocated, and not the
number of bytes used.  This has nothing to do with git.

But, git-gui does not set -eofchar {} on all channels.  To avoid any
further leakage, let's just add this to the Windows specific override of
open.  This override is needed only as long as Tcl 8.x is in use (Tcl
9.0 makes -eofchar {} default on all platforms).

a79e3519d6 commit: use prio_queue_replace() in pop_most_recent_commit()
Optimize pop_most_recent_commit() by adding the first parent using the
more efficient prio_queue_peek() and prio_queue_replace() instead of
prio_queue_get() and prio_queue_put().

3d5091d232 prio-queue: add prio_queue_replace()
Add a function to replace the top element of the queue that basically
does the same as prio_queue_get() followed by prio_queue_put(), but
without the work by prio_queue_get() to rebalance the heap.  It can be
used to optimize loops that get one element and then immediately add
another one.  That's common e.g., with commit history traversal, where
we get out a commit and then put in its parents.

d6ec08788e commit: convert pop_most_recent_commit() to prio_queue
pop_most_recent_commit() calls commit_list_insert_by_date() for parent
commits, which is itself called in a loop.  This can lead to quadratic
complexity if there are many merges.  Replace the commit_list with a
prio_queue to ensure logarithmic worst case complexity and convert all
three users.

Add a performance test that exercises one of them using a pathological
history that consists of 50% merges and 50% root commits to demonstrate
the speedup:

Test                          v2.50.1           HEAD
----------------------------------------------------------------------
1501.2: rev-parse ':/65535'   2.48(2.47+0.00)   0.20(0.19+0.00) -91.9%

Alas, sane histories don't benefit from the conversion much, and
traversing Git's own history takes a 1% performance hit on my machine:
