Process to add some form of low-level unit tests has started.
* js/doc-unit-tests:
ci: run unit tests in CI
unit tests: add TAP unit test framework
unit tests: add a project plan document
In our current testing environment, we spend a significant amount of
effort crafting end-to-end tests for error conditions that could easily
be captured by unit tests (or we simply forgo some hard-to-setup and
rare error conditions). Describe what we hope to accomplish by
implementing unit tests, and explain some open questions and milestones.
Discuss desired features for test frameworks/harnesses, and provide a
comparison of several different frameworks. Finally, document our
rationale for implementing a custom framework.

A long term (but rather minor) pet-peeve of mine was the name
ll-merge.[ch]. I thought it made it harder to realize what stuff was
related to merging when I was working on the merge machinery and trying
to improve it.
Further, back in d1cbe1e6d8 ("hash-ll.h: split out of hash.h to remove
dependency on repository.h", 2023-04-22), we have split the portions of
hash.h that do not depend upon repository.h into a "hash-ll.h" (due to
the recommendation to use "ll" for "low-level" in its name[1], but which
I used as a suffix precisely because of my distaste for "ll-merge").
When we discussed adding additional "*-ll.h" files, a request was made
that we use "ll" consistently as either a prefix or a suffix. Since it
is already in use as both a prefix and a suffix, the only way to do so
is to rename some files.
Besides my distaste for the ll-merge.[ch] name, let me also note that
the files
ll-fsmonitor.h, ll-hash.h, ll-merge.h, ll-object-store.h, ll-read-cache.h
would have essentially nothing to do with each other and make no sense
to group. But giving them the common "ll-" prefix would group them. Using
"-ll" as a suffix thus seems just much more logical to me. Rename
ll-merge.[ch] to merge-ll.[ch] to achieve this consistency, and to
ensure we get a more logical grouping of files.

Once upon a time, Matheus wrote some patches to make
git grep [--cached | <REVISION>] ...
restrict its output to the sparsity specification when working in a
sparse checkout[1]. That effort got derailed by two things:
(1) The --sparse-index work just beginning which we wanted to avoid
creating conflicts for
(2) Never deciding on flag and config names and planned high level
behavior for all commands.
More recently, Shaoxuan implemented a more limited form of Matheus'
patches that only affected --cached, using a different flag name,
but also changing the default behavior in line with what Matheus did.
This again highlighted the fact that we never decided on command line
flag names, config option names, and the big picture path forward.
The --sparse-index work has been mostly complete (or at least released
into production even if some small edges remain) for quite some time
now. We have also had several discussions on flag and config names,
though we never came to solid conclusions. Stolee once upon a time
suggested putting all these into some document in

Add global counters mechanism to Trace2.
The Trace2 counters mechanism adds the ability to create a set of
global counter variables and an API to increment them efficiently.
Counters can optionally report per-thread usage in addition to the sum
across all threads.
Counter events are emitted to the Trace2 logs when a thread exits and
at process exit.
Counters are an alternative to `data` and `data_json` events.
Counters are useful when you want to measure something across the life
of the process, when you don't want per-measurement events for
performance reasons, when the data does not fit conveniently within a
region, or when your control flow does not easily let you write the
final total. For example, you might use this to report the number of
calls to unzip() or the number of de-delta steps during a checkout.

Add stopwatch timer mechanism to Trace2.
Timers are an alternative to Trace2 Regions. Regions are useful for
measuring the time spent in various computation phases, such as the
time to read the index, time to scan for unstaged files, time to scan
for untracked files, and etc.
However, regions are not appropriate in all places. For example,
during a checkout, it would be very inefficient to use regions to
measure the total time spent inflating objects from the ODB from
across the entire lifetime of the process; a per-unzip() region would
flood the output and significantly slow the command; and some form of
post-processing would be requried to compute the time spent in unzip().
Timers can be used to measure a series of timer intervals and emit
a single summary event (at thread and/or process exit).

Two documentation issues exist in the technical docs for the bundle URI
feature.
First, there is an extraneous "the" across a linebreak, making the
nonsensical phrase "the bundle the list" which should just be "the
bundle list".
Secondly, the asciidoc update treats the string "`have`s" as starting a
"<code>" block, but the second tick is interpreted as an apostrophe
instead of a closing "</code>" tag. This causes entire sentences to be
formatted as code until the next one comes along. Simply adding a space
here does not work properly as the rendered HTML keeps that space.
Instead, restructure the sentence slightly to avoid using a plural,
allowing the HTML to render correctly.

When reading bitmap file, Git loads each and every bitmap one by one
even if all the bitmaps are not required. A "bitmap lookup table"
extension to the bitmap format can reduce the overhead of loading
bitmaps which stores a list of bitmapped commit id pos (in the midx
or pack, along with their offset and xor offset. This way Git can
load only the necessary bitmaps without loading the previous bitmaps.
Older versions of Git ignore the lookup table extension and don't
throw any kind of warning or error while parsing the bitmap file.
Add some information for the new "bitmap lookup table" extension in the
bitmap-format documentation.

Several Git commands have subcommands to implement mutually exclusive
"operation modes", and they usually parse their subcommand argument
with a bunch of if-else if statements.
Teach parse-options to handle subcommands as well, which will result
in shorter and simpler code with consistent error handling and error
messages on unknown or missing subcommand, and it will also make
possible for our Bash completion script to handle subcommands
programmatically.
The approach is guided by the following observations:
- Most subcommands [1] are implemented in dedicated functions, and
most of those functions [2] either have a signature matching the
'int cmd_foo(int argc, const char **argc, const char *prefix)'
signature of builtin commands or can be trivially converted to
that signature, because they miss only that last prefix parameter
or have no parameters at all.
- Subcommand arguments only have long form, and they have no double
dash prefix, no negated form, and no description, and they don't
take any arguments, and can't be abbreviated.
- There must be exactly one subcommand among the arguments, or zero
if the command has a default operation mode.
- All arguments following the subcommand are considered to be
arguments of the subcommand, and, conversely, arguments meant for
the subcommand may not preceed the subcommand.
So in the end subcommand declaration and parsing would look something
like this:
parse_opt_subcommand_fn *fn = NULL;
struct option builtin_commit_graph_options[] = {
OPT_STRING(0, "object-dir", &opts.obj_dir, N_("dir"),
N_("the object directory to store the graph")),
OPT_SUBCOMMAND("verify", &fn, graph_verify),
OPT_SUBCOMMAND("write", &fn, graph_write),
OPT_END(),
};
argc = parse_options(argc, argv, prefix, options,
builtin_commit_graph_usage, 0);
return fn(argc, argv, prefix);
Here each OPT_SUBCOMMAND specifies the name of the subcommand and the
function implementing it, and the address of the same 'fn' subcommand
function pointer. parse_options() then processes the arguments until
it finds the first argument matching one of the subcommands, sets 'fn'
to the function associated with that subcommand, and returns, leaving
the rest of the arguments unprocessed. If none of the listed
subcommands is found among the arguments, parse_options() will show
usage and abort.
If a command has a default operation mode, 'fn' should be initialized
to the function implementing that mode, and parse_options() should be
invoked with the PARSE_OPT_SUBCOMMAND_OPTIONAL flag. In this case
parse_options() won't error out when not finding any subcommands, but
will return leaving 'fn' unchanged. Note that if that default
operation mode has any --options, then the PARSE_OPT_KEEP_UNKNOWN_OPT
flag is necessary as well (otherwise parse_options() would error out
upon seeing the unknown option meant to the default operation mode).
Some thoughts about the implementation:
- The same pointer to 'fn' must be specified as 'value' for each
OPT_SUBCOMMAND, because there can be only one set of mutually
exclusive subcommands; parse_options() will BUG() otherwise.
There are other ways to tell parse_options() where to put the
function associated with the subcommand given on the command line,
but I didn't like them:
- Change parse_options()'s signature by adding a pointer to
subcommand function to be set to the function associated with
the given subcommand, affecting all callsites, even those that
don't have subcommands.
- Introduce a specific parse_options_and_subcommand() variant
with that extra funcion parameter.
- I decided against automatically calling the subcommand function
from within parse_options(), because:
- There are commands that have to perform additional actions
after option parsing but before calling the function
implementing the specified subcommand.
- The return code of the subcommand is usually the return code
of the git command, but preserving the return code of the
automatically called subcommand function would have made the
API awkward.
- Also add a OPT_SUBCOMMAND_F() variant to allow specifying an
option flag: we have two subcommands that are purposefully
excluded from completion ('git remote rm' and 'git stash save'),
so they'll have to be specified with the PARSE_OPT_NOCOMPLETE
flag.
- Some of the 'parse_opt_flags' don't make sense with subcommands,
and using them is probably just an oversight or misunderstanding.
Therefore parse_options() will BUG() when invoked with any of the
following flags while the options array contains at least one
OPT_SUBCOMMAND:
- PARSE_OPT_KEEP_DASHDASH: parse_options() stops parsing
arguments when encountering a "--" argument, so it doesn't
make sense to expect and keep one before a subcommand, because
it would prevent the parsing of the subcommand.
However, this flag is allowed in combination with the
PARSE_OPT_SUBCOMMAND_OPTIONAL flag, because the double dash
might be meaningful for the command's default operation mode,
e.g. to disambiguate refs and pathspecs.
- PARSE_OPT_STOP_AT_NON_OPTION: As its name suggests, this flag
tells parse_options() to stop as soon as it encouners a
non-option argument, but subcommands are by definition not
options... so how could they be parsed, then?!
- PARSE_OPT_KEEP_UNKNOWN: This flag can be used to collect any
unknown --options and then pass them to a different command or
subsystem. Surely if a command has subcommands, then this
functionality should rather be delegated to one of those
subcommands, and not performed by the command itself.
However, this flag is allowed in combination with the
PARSE_OPT_SUBCOMMAND_OPTIONAL flag, making possible to pass
--options to the default operation mode.
- If the command with subcommands has a default operation mode, then
all arguments to the command must preceed the arguments of the
subcommand.
AFAICT we don't have any commands where this makes a difference,
because in those commands either only the command accepts any
arguments ('notes' and 'remote'), or only the default subcommand
('reflog' and 'stash'), but never both.
- The 'argv' array passed to subcommand functions currently starts
with the name of the subcommand. Keep this behavior. AFAICT no
subcommand functions depend on the actual content of 'argv[0]',
but the parse_options() call handling their options expects that
the options start at argv[1].
- To support handling subcommands programmatically in our Bash
completion script, 'git cmd --git-completion-helper' will now list
both subcommands and regular --options, if any. This means that
the completion script will have to separate subcommands (i.e.
words without a double dash prefix) from --options on its own, but
that's rather easy to do, and it's not much work either, because
the number of subcommands a command might have is rather low, and
those commands accept only a single --option or none at all. An
alternative would be to introduce a separate option that lists
only subcommands, but then the completion script would need not
one but two git invocations and command substitutions for commands
with subcommands.
Note that this change doesn't affect the behavior of our Bash
completion script, because when completing the --option of a
command with subcommands, e.g. for 'git notes --<TAB>', then all
subcommands will be filtered out anyway, as none of them will
match the word to be completed starting with that double dash
prefix.
[1] Except 'git rerere', because many of its subcommands are
implemented in the bodies of the if-else if statements parsing the
command's subcommand argument.
[2] Except 'credential', 'credential-store' and 'fsmonitor--daemon',
because some of the functions implementing their subcommands take
special parameters.
