short help: allow a gap smaller than USAGE_GAP
remote: simplify "remote add --tags" help text
short help: allow multi-line opthelp
The help text for the --tags option was split into two option[]
entries, which was a hacky way to give two lines of help text (the
second entry did not have either short or long help, and there was
no way to invoke its entry---it was there only for the help text).
As we now support multi-line text in the option help, let's make
the second line of the help a proper second line and remove the
hacky second entry.

Pass config_context to config callbacks in configset_iter(), trivially
setting the .kvi member to the cached key_value_info. Then, in config
callbacks that are only used with configsets, use the .kvi member to
replace calls to current_config_*(), and delete current_config_line()
because it has no remaining callers.
This leaves builtin/config.c and config.c as the only remaining users of
current_config_*().

Add a new "const struct config_context *ctx" arg to config_fn_t to hold
additional information about the config iteration operation.
config_context has a "struct key_value_info kvi" member that holds
metadata about the config source being read (e.g. what kind of config
source it is, the filename, etc). In this series, we're only interested
in .kvi, so we could have just used "struct key_value_info" as an arg,
but config_context makes it possible to add/adjust members in the future
without changing the config_fn_t signature. We could also consider other
ways of organizing the args (e.g. moving the config name and value into
config_context or key_value_info), but in my experiments, the
incremental benefit doesn't justify the added complexity (e.g. a
config_fn_t will sometimes invoke another config_fn_t but with a
different config value).
In subsequent commits, the .kvi member will replace the global "struct
config_reader" in config.c, making config iteration a global-free
operation. It requires much more work for the machinery to provide
meaningful values of .kvi, so for now, merely change the signature and
call sites, pass NULL as a placeholder value, and don't rely on the arg
in any meaningful way.
Most of the changes are performed by
contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every
config_fn_t:
- Modifies the signature to accept "const struct config_context *ctx"
- Passes "ctx" to any inner config_fn_t, if needed
- Adds UNUSED attributes to "ctx", if needed
Most config_fn_t instances are easily identified by seeing if they are
called by the various config functions. Most of the remaining ones are
manually named in the .cocci patch. Manual cleanups are still needed,
but the majority of it is trivial; it's either adjusting config_fn_t
that the .cocci patch didn't catch, or adding forward declarations of
"struct config_context ctx" to make the signatures make sense.
The non-trivial changes are in cases where we are invoking a config_fn_t
outside of config machinery, and we now need to decide what value of
"ctx" to pass. These cases are:
- trace2/tr2_cfg.c:tr2_cfg_set_fl()
This is indirectly called by git_config_set() so that the trace2
machinery can notice the new config values and update its settings
using the tr2 config parsing function, i.e. tr2_cfg_cb().
- builtin/checkout.c:checkout_main()
This calls git_xmerge_config() as a shorthand for parsing a CLI arg.
This might be worth refactoring away in the future, since
git_xmerge_config() can call git_default_config(), which can do much
more than just parsing.
Handle them by creating a KVI_INIT macro that initializes "struct
key_value_info" to a reasonable default, and use that to construct the
"ctx" arg.

We return an error when trying to rename a remote that has no fetch

fatal: could not unset 'remote.foo.fetch'
To make things even more confusing, we actually _do_ complete the config
modification, via git_config_rename_section(). After that we try to
rewrite the fetch refspec (to say refs/remotes/foo instead of origin).
But our call to git_config_set_multivar() to remove the existing entries
fails, since there aren't any, and it calls die().
We could fix this by using the "gently" form of the config call, and
checking the error code. But there is an even simpler fix: if we know
that there are no refspecs to rewrite, then we can skip that part
entirely.

The "git remote rm" command's option parsing is fairly primitive: it
insists on a single argument, which it treats as the remote name, and
displays a usage message otherwise.
This is OK, and maybe even convenient, as you could run:
git remote rm --foo
to drop a remote named "--foo". But it's also weirdly unlike most of the
rest of Git, which would complain that there is no option "--foo". The
right way to spell it by our conventions is:
git remote rm -- --foo
but this doesn't currently work.
So let's bring the command in line with the rest of Git (including its
sibling subcommands!) by feeding argv to parse_options(). We already
have an empty options array for the usage helper.
Note that we have to adjust the argc index down by one, as
parse_options() eats the program name from the start of the array.

Recent commits such as bf0a6b65fc (builtin/multi-pack-index.c: let
parse-options parse subcommands, 2022-08-19) converted a few functions
to match our usual argc/argv/prefix conventions, but the prefix argument
remains unused.
However, there is a good use for it: they should pass it to their own
parse_options() functions, where it may be used to adjust the value of
any filename options. In all but one of these functions, there's no
behavior change, since they don't use OPT_FILENAME. But this is an
actual fix for one option, which you can see by modifying the test suite
like so:
diff --git a/t/t5326-multi-pack-bitmaps.sh b/t/t5326-multi-pack-bitmaps.sh

I'd emphasize that this wasn't broken by bf0a6b65fc; it has been broken
all along, because the sub-function never got to see the prefix. It is
that commit which is actually enabling us to fix it (and which also
brought attention to the problem because it triggers -Wunused-parameter!)
The other functions changed here don't use OPT_FILENAME at all. In their
cases this isn't fixing anything visible, but it's following the usual
pattern and future-proofing them against somebody adding new options and
being surprised.
I didn't include a test for the one visible case above. We don't
generally test routine parse-options behavior for individual options.
The challenge here was finding the problem, and now that this has been
done, it's not likely to regress. Likewise, we could apply the patch
above to cover it "for free" but it makes reading the rest of the test
unnecessarily complicated.

'git remote' parses its subcommands with a long list of if-else if
statements. parse-options has just learned to parse subcommands, so
let's use that facility instead, with the benefits of shorter code,
handling unknown subcommands, and listing subcommands for Bash
completion. Make sure that the default operation mode doesn't accept
any arguments; and while at it remove the capitalization of the error
message and adjust the test checking it accordingly.
Note that 'git remote' has both 'remove' and 'rm' subcommands, and the
former is preferred [1], so hide the latter for completion.
Note also that the functions implementing each subcommand only accept
the 'argc' and '**argv' parameters, so add a (unused) '*prefix'
parameter to make them match the type expected by parse-options, and
thus avoid casting a bunch of function pointers.

By default, the git remote show command will query data from remotes to
show data about what might be done on a future git fetch. This process
currently does not handle negative refspecs. This can be confusing,
because the show command will list refs as if they would be fetched. For
example if the fetch refspec "^refs/heads/pr/*", it still displays the
following:
* remote jdk19
Fetch URL: git@github.com:openjdk/jdk19.git
Push URL: git@github.com:openjdk/jdk19.git
HEAD branch: master
Remote branches:
master tracked
pr/1 new (next fetch will store in remotes/jdk19)
pr/2 new (next fetch will store in remotes/jdk19)
pr/3 new (next fetch will store in remotes/jdk19)
Local ref configured for 'git push':
master pushes to master (fast-forwardable)
Fix this by adding an additional check inside of get_ref_states. If a
ref matches one of the negative refspecs, mark it as skipped instead of
marking it as new or tracked.
With this change, we now report remote branches that are skipped due to
negative refspecs properly:
* remote jdk19
Fetch URL: git@github.com:openjdk/jdk19.git
Push URL: git@github.com:openjdk/jdk19.git
HEAD branch: master
Remote branches:
master tracked
pr/1 skipped
pr/2 skipped
pr/3 skipped
Local ref configured for 'git push':
master pushes to master (fast-forwardable)
By showing the refs as skipped, it helps clarify that these references
won't actually be fetched.
This does not properly handle refs going stale due to a newly added
negative refspec. In addition, git remote prune doesn't handle that
negative refspec case either. Fixing that requires digging into
get_stale_heads and handling the case of a ref which exists on the
remote but is omitted due to a negative refspec locally.
Add a new test case which covers the functionality above, as well as a
new expected failure indicating the poor overlap with stale refs.

When renaming a remote, Git needs to rename all remote tracking
references to the remote's new name (e.g., renaming
"refs/remotes/old/foo" to "refs/remotes/new/foo" when renaming a remote
from "old" to "new").
This can be somewhat slow when there are many references to rename,
since each rename is done in a separate call to rename_ref() as opposed
to grouping all renames together into the same transaction. It would be
nice to execute all renames as a single transaction, but there is a
snag: the reference transaction backend doesn't support renames during a
transaction (only individually, via rename_ref()).
The reasons there are described in more detail in [1], but the main
problem is that in order to preserve the existing reflog, it must be
moved while holding both locks (i.e., on "oldname" and "newname"), and
the ref transaction code doesn't support inserting arbitrary actions
into the middle of a transaction like that.
As an aside, adding support for this to the ref transaction code is
less straightforward than inserting both a ref_update() and ref_delete()
call into the same transaction. rename_ref()'s special handling to
detect D/F conflicts would need to be rewritten for the transaction code
if we wanted to proactively catch D/F conflicts when renaming a
reference during a transaction. The reftable backend could support this
much more readily because of its lack of D/F conflicts.
Instead of a more complex modification to the ref transaction code,
display a progress meter when running verbosely in order to convince the
user that Git is doing work while renaming a remote.
This is mostly done as-expected, with the minor caveat that we
intentionally count symrefs renames twice, since renaming a symref takes
place over two separate calls (one to delete the old one, and another to
create the new one).

But the subsequent patch will add a `--[no-]progress` option, in which
case we will need to call parse_options().
Do so now so as to avoid cluttering the following patch with noise, like

style for push refspecs, 2009-02-25) we added some more of these.
As it turns out we only initialized this struct three times, all the
other uses were of pointers to those initialized structs. So let's
initialize it in those three places, skip the memset(), and pass those
structs down appropriately.
This would be a behavior change if we had codepaths that relied say on
implicitly having had "new_refs" initialized to STRING_LIST_INIT_NODUP
with the memset(), but only set the "strdup_strings" on some other
struct, but then called string_list_append() on "new_refs". There
isn't any such codepath, all of the late assignments to
"strdup_strings" assigned to those structs that we'd use for those
codepaths.
So just initializing them all up-front makes for easier to understand
code, i.e. in the pre-image it looked as though we had that tricky
edge case, but we didn't.

We ignore them silently, but it actually makes sense to warn the users
that their config setting has no effect.

Plug or annotate remaining leaks that trigger while running the
very basic set of tests.
* ah/plugleaks:
transport: also free remote_refs in transport_disconnect()
parse-options: don't leak alias help messages
parse-options: convert bitfield values to use binary shift
init-db: silence template_dir leak when converting to absolute path
init: remove git_init_db_config() while fixing leaks
worktree: fix leak in dwim_branch()
clone: free or UNLEAK further pointers when finished
reset: free instead of leaking unneeded ref
symbolic-ref: don't leak shortened refname in check_symref()
transport_get_remote_refs() can populate the transport struct's
remote_refs. transport_disconnect() is already responsible for most of
transport's cleanup - therefore we also take care of freeing remote_refs
there.
There are 2 locations where transport_disconnect() is called before
we're done using the returned remote_refs. This patch changes those
callsites to only call transport_disconnect() after the returned refs
are no longer being used - which is necessary to safely be able to
free remote_refs during transport_disconnect().
This commit fixes the following leak which was found while running
t0000, but is expected to also fix the same pattern of leak in all
locations that use transport_get_remote_refs():
Direct leak of 165 byte(s) in 1 object(s) allocated from:

When a remote is renamed don't change the canonical "*.pushRemote"
form to "*.pushremote". Fixes and tests for a minor bug in
923d4a5ca4 (remote rename/remove: handle branch.<name>.pushRemote
config values, 2020-01-27). See the preceding commit for why this does
& doesn't matter.
While we're at it let's also test that we handle the "*.pushDefault"
key correctly. The code to handle that was added in
b3fd6cbf29 (remote rename/remove: gently handle remote.pushDefault
config, 2020-02-01) and does the right thing, but nothing tested that
we wrote out the canonical camel-cased form.

Change "git remote add" so that it adds a *.tagOpt key, and not the
lower-cased *.tagopt on "git remote add --no-tags", just as "git clone
--no-tags" would do.
This doesn't matter for anything that reads the config. It's just
prettier if we write config keys in their documented camelCase form to
user-readable config files.
When I added support for "clone -no-tags" in 0dab2468ee (clone: add a
--no-tags option to clone without tags, 2017-04-26) I made it use
the *.tagOpt form, but the older "git remote add" added in
111fb85865 (remote add: add a --[no-]tags option, 2010-04-20) has
been using *.tagopt all this time.
It's easy enough to add a test for this, so let's do that. We can't
use "git config -l" there, because it'll normalize the keys to their
lower-cased form. Let's add the test for "git clone" too for good
measure, not just to the "git remote" codepath we're fixing.

We will extend the flexibility of the config API. Before doing so, let's
take an existing 'int multi_replace' parameter and replace it with a new
'unsigned flags' parameter that can take multiple options as a bit field.
Update all callers that specified multi_replace to now specify the
CONFIG_FLAGS_MULTI_REPLACE flag. To add more clarity, extend the
documentation of git_config_set_multivar_in_file() including a clear
labeling of its arguments. Other config API methods in config.h require
only a change of the final parameter from 'int' to 'unsigned'.

Exit codes from "git remote add" etc. were not usable by scripted
callers.
* ab/git-remote-exit-code:
remote: add meaningful exit code on missing/existing
"git clone" learned clone.defaultremotename configuration variable
to customize what nickname to use to call the remote the repository
was cloned from.

clone: allow configurable default for `-o`/`--origin`
clone: read new remote name from remote_name instead of option_origin
clone: validate --origin option before use
refs: consolidate remote name validation
remote: add tests for add and rename with invalid names
clone: use more conventional config/option layering
clone: add tests for --template and some disallowed option pairs
