Some trace2 events that lacked def_param have learned to show it,

"git --no-lazy-fetch cmd" allows to run "cmd" while disabling lazy
fetching of objects from the promisor remote, which may be handy
for debugging.

Some commands do not cause a set of 'def_param' events to be emitted.
This includes "git-remote-https", "git-http-fetch", and various
"query" commands, like "git --man-path".
Since all of these commands do emit a 'cmd_name' event, add code to
the "trace2_cmd_name()" function to generate the set of 'def_param'
events.
Remove explicit calls to "trace2_cmd_list_config()" and
"trace2_cmd_list_env_vars()" in git.c since they are no longer needed.

Modeling after how the `--no-replace-objects` option is made usable
across subprocess spawning (e.g., cURL based remote helpers are
spawned as a separate process while running "git fetch"), allow the
`--no-lazy-fetch` option to be passed across process boundaries.
Do not model how the value of GIT_NO_REPLACE_OBJECTS environment
variable is ignored, though. Just use the usual git_env_bool() to
allow "export GIT_NO_LAZY_FETCH=0" and "unset GIT_NO_LAZY_FETCH"
to be equivalents.
Also do not model how the request is not propagated to subprocesses
we spawn (e.g. "git clone --local" that spawns a new process to work
in the origin repository, while the original one working in the
newly created one) by the "--no-replace-objects" option, as this "do
not lazily fetch from the promisor" is more about a per-request
debugging aid, not "this repository's promisor should not be relied
upon" property specific to a repository.

Sometimes, especially during tests of low level machinery, it is
handy to have a way to disable lazy fetching of objects. This
allows us to say, for example, "git cat-file -e <object-name>", to
see if the object is locally available.

For now, this is just a rename from `t/helper/test-fast-rebase.c` into
`builtin/replay.c` with minimal changes to make it build appropriately.
Let's add a stub documentation and a stub test script though.
Subsequent commits will flesh out the capabilities of the new command
and make it a more standard regular builtin.

For the functions defined in read-cache.c, move their declarations from
cache.h to a new header, read-cache-ll.h. Also move some related inline
functions from cache.h to read-cache.h. The purpose of the
read-cache-ll.h/read-cache.h split is that about 70% of the sites don't
need the inline functions and the extra headers they include.

Several builtins depend on being able to disable the replace references
so we actually operate on each object individually. These currently do
so by directly mutating the 'read_replace_refs' global.
A future change will move this global into a different place, so it will
be necessary to change all of these lines. However, we can simplify that
transition by abstracting the purpose of these global assignments with a
method call.
We will need to keep this read_replace_refs global forever, as we want
to make sure that we never use replace refs throughout the life of the
process if this method is called. Future changes may present a
repository-scoped version of the variable to represent that repository's
core.useReplaceRefs config value, but a zero-valued read_replace_refs
will always override such a setting.

Earlier, 47cfc9bd (attr: add flag `--source` to work with tree-ish,
2023-01-14) taught "git check-attr" the "--source=<tree>" option to
allow it to read attribute files from a tree-ish, but did so only
for the command. Just like "check-attr" users wanted a way to use
attributes from a tree-ish and not from the working tree files,
users of other commands (like "git diff") would benefit from the
same.
Undo most of the UI change the commit made, while keeping the
internal logic to read attributes from a given tree-ish. Expose the
internal logic via a new "--attr-source=<tree>" command line option
given to "git", so that it can be used with any git command that
runs as part of the main git process.
Additionally, add an environment variable GIT_ATTR_SOURCE that is set
when --attr-source is passed in, so that subprocesses use the same value
for the attributes source tree.

trace_repo_setup() of trace.c is called with the argument 'prefix' from
only one location, run_builtin of git.c, which sets 'prefix' to the return
value of setup_git_directory() or setup_git_directory_gently() (a wrapper
of the former).
Now that "prefix" is in startup_info there is no need for the parameter
of trace_repo_setup() because setup_git_directory() sets "startup_info->prefix"
to the same value it returns. It would be less confusing to use "prefix"
from startup_info instead of passing it as an argument.

Remove "git env--helper" and demote it to a test-tool subcommand.
* ab/test-env-helper:
env-helper: move this built-in to "test-tool env-helper"
|
|
Since [1] there has been no reason for keeping "git env--helper" a
built-in. The reason it was a built-in to begin with was to support
the GIT_TEST_GETTEXT_POISON mode removed in that commit. I.e. unlike
the rest of "test-tool" it would potentially be called by the
installed git via "git-sh-i18n.sh".
As none of that applies since [1] we should stop carrying this
technical debt, and move it to t/helper/*. As this mostly move-only
change shows this has the nice bonus that we'll stop wasting time
translating the internal-only strings it emits.
Even though this was a built-in, it was intentionally never
documented, see its introduction in [2]. It never saw use outside of
the test suite, except for the "GIT_TEST_GETTEXT_POISON" use-case
noted above.

The "--super-prefix" option to "git" was initially added in [1] for
use with "ls-files"[2], and shortly thereafter "submodule--helper"[3]
and "grep"[4]. It wasn't until [5] that "read-tree" made use of it.
At the time [5] made sense, but since then we've made "ls-files"
recurse in-process in [6], "grep" in [7], and finally
"submodule--helper" in the preceding commits.
Let's also remove it from "read-tree", which allows us to remove the
option to "git" itself.
We can do this because the only remaining user of it is the submodule
API, which will now invoke "read-tree" with its new "--super-prefix"
option. It will only do so when the "submodule_move_head()" function
is called.
That "submodule_move_head()" function was then only invoked by
"read-tree" itself, but now rather than setting an environment
variable to pass "--super-prefix" between cmd_read_tree() we:
- Set a new "super_prefix" in "struct unpack_trees_options". The
"super_prefixed()" function in "unpack-trees.c" added in [5] will now
use this, rather than get_super_prefix() looking up the environment
variable we set earlier in the same process.
- Add the same field to the "struct checkout", which is only needed to
ferry the "super_prefix" in the "struct unpack_trees_options" all the
way down to the "entry.c" callers of "submodule_move_head()".
Those calls which used the super prefix all originated in
"cmd_read_tree()". The only other caller is the "unlink_entry()"
caller in "builtin/checkout.c", which now passes a "NULL".

As with a preceding commit to convert "absorbgitdirs", we can convert
"submodule--helper status" to use its own "--super-prefix", instead of
relying on the global "--super-prefix" argument to "git".
We need to convert both of these away from the global "--super-prefix"
at the same time, because "update" will call "clone", but "clone"
itself didn't make use of the global "--super-prefix" for displaying
paths. It was only on the list of sub-commands that accepted it
because "update"'s use of it would set it in its environment.

The "--super-prefix" facility was introduced in [1] has always been a
transitory hack, which is why we've made it an error to supply it as
an option to "git" to commands that don't know about it.
That's been a good goal, as it has a global effect we haven't wanted
calls to get_super_prefix() from built-ins we didn't expect.
But it has meant that when we've had chains of different built-ins
using it all of the processes in that "chain" have needed to support
it, and worse processes that don't need it have needed to ask for
"SUPPORT_SUPER_PREFIX" because their parent process needs it.
That's how "fsmonitor--daemon" ended up with it, per [2] it's called
from (among other things) "submodule--helper absorbgitdirs", but as we
declared "submodule--helper" as "SUPPORT_SUPER_PREFIX" we needed to
declare "fsmonitor--daemon" as accepting it too, even though it
doesn't care about it.
But in the case of "absorbgitdirs" it only needed "--super-prefix" to
invoke itself recursively, and we'd never have another "in-between"
process in the chain. So we didn't need the bigger hammer of "git
--super-prefix", and the "setenv(GIT_SUPER_PREFIX_ENVIRONMENT, ...)"
that it entails.
Let's instead accept a hidden "--super-prefix" option to
"submodule--helper absorbgitdirs" itself.
Eventually (as with all other "--super-prefix" users) we'll want to
clean this code up so that this all happens in-process. I.e. needing
any variant of "--super-prefix" is itself a hack around our various
global state, and implicit reliance on "the_repository". This stepping
stone makes such an eventual change easier, as we'll need to deal with
less global state at that point.
The "fsmonitor--daemon" test adjusted here was added in [3]. To assert
that it didn't run into the "--super-prefix" message it was asserting
the output it didn't have. Let's instead assert the full output that
we *do* have, using the same pattern as a preceding change to
"t/t7412-submodule-absorbgitdirs.sh" used.
We could also remove the test entirely (as [4] did), but even though
the initial reason for having it is gone we're still getting some
marginal benefit from testing the "fsmonitor" and "submodule
absorbgitdirs" interaction, so let's keep it.
The change here to have either a NULL or non-"" string as a
"super_prefix" instead of the previous arrangement of "" or non-"" is
somewhat arbitrary. We could also decide to never have to check for
NULL.
As we'll be changing the rest of the "git --super-prefix" users to the
same pattern, leaving them all consistent makes sense. Why not pick ""
over NULL? Because that's how the "prefix" works[5], and having
"prefix" and "super_prefix" work the same way will be less
confusing. That "prefix" picked NULL instead of "" is itself
arbitrary, but as it's easy to make this small bit of our overall API
consistent, let's go with that.

let's use that facility instead, with the benefits of shorter code,

This change makes 'git maintenance' consistent with other commands in
that the help text shown for '-h' goes to standard output, not error,
in the exit code and error message on unknown subcommand, and the
error message on missing subcommand. There is a test checking these,
which is now updated accordingly.
Note that some of the functions implementing each subcommand don't
accept any parameters, so add the (unused) 'argc', '**argv' and
'*prefix' parameters to make them match the type expected by
parse-options, and thus avoid casting function pointers.

Our Bash completion script can complete --options for commands using
parse-options even when that command doesn't have a dedicated
completion function, but to do so the completion script must know
which commands use parse-options and which don't. Therefore, commands
not using parse-options are marked in 'git.c's command list with the
NO_PARSEOPT flag.
Update this list, and remove this flag from the commands that by now
use parse-options.
After this change we can TAB complete --options of the plumbing
commands 'commit-tree', 'mailinfo' and 'mktag'.

Create a 'git diagnose' builtin to generate a standalone zip archive of
repository diagnostics.
The "diagnose" functionality was originally implemented for Scalar in
aa5c79a331 (scalar: implement `scalar diagnose`, 2022-05-28). However, the
diagnostics gathered are not specific to Scalar-cloned repositories and
can be useful when diagnosing issues in any Git repository.

Let merge-tree accept a `--write-tree` parameter for choosing real
merges instead of trivial merges, and accept an optional
`--trivial-merge` option to get the traditional behavior. Note that
these accept different numbers of arguments, though, so these names
need not actually be used.
Note that real merges differ from trivial merges in that they handle:
- three way content merges
- recursive ancestor consolidation
- renames
- proper directory/file conflict handling
- etc.
Basically all the stuff you'd expect from `git merge`, just without
updating the index and working tree. The initial shell added here does
nothing more than die with "real merges are not yet implemented", but
that will be fixed in subsequent commits.

Create a test in t7527 to verify that we get a stray warning from
`git fsmonitor--daemon start` when indirectly called from
`git submodule absorbgitdirs`.
Update `git fsmonitor--daemon` to take (and ignore) the `--super-prefix`
argument to suppress the warning.
When we have:
1. a submodule with a `sub/.git/` directory (rather than a `sub/.git`
file).
2. `core.fsmonitor` is turned on in the submodule, but the daemon is
not yet started in the submodule.
3. and someone does a `git submodule absorbgitdirs` in the super.
Git will recursively invoke `git submodule--helper absorb-git-dirs`
in the submodule. This will read the index and may attempt to start
the fsmonitor--daemon with the `--super-prefix` argument.
`git fsmonitor--daemon start` does not accept the `--super-prefix`
argument and causes a warning to be issued.
This does not cause a problem because the `refresh_index()` code
assumes a trivial response if the daemon does not start.
The net-net is a harmelss, but stray warning. Lets eliminate the
warning.

"git -v" and "git -h" are now understood as "git --version" and
"git --help".
* gf/shorthand-version-and-help:
cli: add -v and -h shorthands
|
|
Change the behavior of "git -v" to be synonymous with "--version" /
"version", and "git -h" to be synonymous with "--help", but not "help".
These shorthands both display the "unknown option" message. Following
this change, "-v" displays the version, and "-h" displays the help text
of the "git" command.
It should be noted that the "-v" shorthand could be misinterpreted by
the user to mean "verbose" instead of "version", since some sub-commands
make use of it in this context. The top-level "git" command does not
have a "verbose" flag, so it's safe to introduce this shorthand
unambiguously.

Create a built-in file system monitoring daemon that can be used by
the existing `fsmonitor` feature (protocol API and index extension)
to improve the performance of various Git commands, such as `status`.
The `fsmonitor--daemon` feature builds upon the `Simple IPC` API and
provides an alternative to hook access to existing fsmonitors such
as `watchman`.
This commit merely adds the new command without any functionality.

Some code clean-up in the "git grep" machinery.
* ab/grep-patterntype:
grep: simplify config parsing and option parsing
grep.c: do "if (bool && memchr())" not "if (memchr() && bool)"
grep.h: make "grep_opt.pattern_type_option" use its enum
grep API: call grep_config() after grep_init()
grep.c: don't pass along NULL callback value
built-ins: trust the "prefix" from run_builtin()
grep tests: add missing "grep.patternType" config tests
grep tests: create a helper function for "BRE" or "ERE"
log tests: check if grep_config() is called by "log"-like cmds
grep.h: remove unused "regex_t regexp" from grep_opt
|
|
Change code in "builtin/grep.c" and "builtin/ls-tree.c" to trust the
"prefix" passed from "run_builtin()". The "prefix" we get from setup.c
is either going to be NULL or a string of length >0, never "".
So we can drop the "prefix && *prefix" checks added for
"builtin/grep.c" in 0d042fecf2f (git-grep: show pathnames relative to
the current directory, 2006-08-11), and for "builtin/ls-tree.c" in
a69dd585fca (ls-tree: chomp leading directories when run from a
subdirectory, 2005-12-23).
As seen in code in revision.c that was added in cd676a51367 (diff
--relative: output paths as relative to the current subdirectory,
2008-02-12) we already have existing code that does away with this
assertion.
This makes it easier to reason about a subsequent change to the
"prefix_length" code in grep.c in a subsequent commit, and since we're
going to the trouble of doing that let's leave behind an assert() to
promise this to any future callers.
For "builtin/grep.c" it would be painful to pass the "prefix" down the
callchain of:
cmd_grep -> grep_tree -> grep_submodule -> grep_cache -> grep_oid ->
grep_source_name
So for the code that needs it in grep_source_name() let's add a
"grep_prefix" variable similar to the existing "ls_tree_prefix".
While at it let's move the code in cmd_ls_tree() around so that we
assign to the "ls_tree_prefix" right after declaring the variables,
and stop assigning to "prefix". We only subsequently used that
variable later in the function after clobbering it. Let's just use our
own "grep_prefix" instead.
Let's also add an assert() in git.c, so that we'll make this promise
about the "prefix" to any current and future callers, as well as to
any readers of the code.
Code history:
* The strlen() in "grep.c" hasn't been used since 493b7a08d80 (grep:
accept relative paths outside current working directory, 2009-09-05).
When that code was added in 0d042fecf2f (git-grep: show pathnames
relative to the current directory, 2006-08-11) we used the length.
But since 493b7a08d80 we haven't used it for anything except a
boolean check that we could have done on the "prefix" member
itself.

More "config-based hooks".
* ab/config-based-hooks-2:
run-command: remove old run_hook_{le,ve}() hook API
receive-pack: convert push-to-checkout hook to hook.h
read-cache: convert post-index-change to use hook.h
commit: convert {pre-commit,prepare-commit-msg} hook to hook.h
git-p4: use 'git hook' to run hooks
send-email: use 'git hook run' for 'sendemail-validate'
git hook run: add an --ignore-missing flag
hooks: convert worktree 'post-checkout' hook to hook library
hooks: convert non-worktree 'post-checkout' hook to hook library
merge: convert post-merge to use hook.h
am: convert applypatch-msg to use hook.h
rebase: convert pre-rebase to use hook.h
hook API: add a run_hooks_l() wrapper
am: convert {pre,post}-applypatch to use hook.h
gc: use hook library for pre-auto-gc hook
hook API: add a run_hooks() wrapper
hook: add 'run' subcommand
|
|
In order to enable hooks to be run as an external process, by a
standalone Git command, or by tools which wrap Git, provide an external
means to run all configured hook commands for a given hook event.
Most of our hooks require more complex functionality than this, but
let's start with the bare minimum required to support our simplest
hooks.
In terms of implementation the usage_with_options() and "goto usage"
pattern here mirrors that of
builtin/{commit-graph,multi-pack-index}.c.
Some of the implementation here, such as a function being named
run_hooks_opt() when it's tasked with running one hook, to using the
run_processes_parallel_tr2() API to run with jobs=1 is somewhere
between a bit odd and and an overkill for the current features of this
"hook run" command and the hook.[ch] API.
This code will eventually be able to run multiple hooks declared in
config in parallel, by starting out with these names and APIs we
reduce the later churn of renaming functions, switching from the
run_command() to run_processes_parallel_tr2() API etc.
