Taylor Blau 56710a7ae0 builtin/remote.c: show progress when renaming remote references
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).

Taylor Blau c6dddb34b5 builtin/remote.c: parse options in 'rename'
The 'git remote rename' command doesn't currently take any command-line
arguments besides the existing and new name of a remote, and so has no
need to call parse_options().

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
adjusting setting `rename.{old,new}_name` to argv[0] and argv[1], since
parse_options handles advancing argv past the name of the sub-command.

Patrick Steinhardt 1553f5e76c remote: read symbolic refs via `refs_read_symbolic_ref()`
We have two cases in the remote code where we check whether a reference
is symbolic or not, but don't mind in case it doesn't exist or in case
it exists but is a non-symbolic reference. Convert these two callsites
to use the new `refs_read_symbolic_ref()` function, whose intent is to
implement exactly that usecase.

No change in behaviour is expected from this change.

Ævar Arnfjörð Bjarmason 0000e81811 builtin/remote.c: add and use SHOW_INFO_INIT
In the preceding commit we introduced REF_STATES_INIT, but did not
change the "struct show_info" to have a corresponding
initializer. Let's do that, and make it use "REF_STATES_INIT" and
"STRING_LIST_INIT_DUP", doing that requires changing "list" and
"states" away from being pointers.

The resulting end-state is simpler since we omit the local "info_list"
and "states" variables in show() as well as the memset().

Ævar Arnfjörð Bjarmason 0bc7787ca9 builtin/remote.c: add and use a REF_STATES_INIT
Use a new REF_STATES_INIT designated initializer instead of assigning
to the "strdup_strings" member of the previously memzero()'d version
of this struct.

The pattern of assigning to "strdup_strings" dates back to
211c89682e (Make git-remote a builtin, 2008-02-29) (when it was
"strdup_paths"), i.e. long before we used anything like our current
established *_INIT patterns consistently.

Then in e61e0cc6b7 (builtin-remote: teach show to display remote
HEAD, 2009-02-25) and e5dcbfd9ab (builtin-remote: new show output
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.

Andrzej Hunt 68ffe095a2 transport: also free remote_refs in transport_disconnect()
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():

Ævar Arnfjörð Bjarmason 0f1da600e6 remote: write camel-cased *.pushRemote on rename

923d4a5ca4 (remote rename/remove: handle branch.<name>.pushRemote

& 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.

Ævar Arnfjörð Bjarmason bfa9148ff7 remote: add camel-cased *.tagOpt key, like clone
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

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

Ævar Arnfjörð Bjarmason 9144ba4cf5 remote: add meaningful exit code on missing/existing
Change the exit code for the likes of "git remote add/rename" to exit
with 2 if the remote in question doesn't exist, and 3 if it
does. Before we'd just die() and exit with the general 128 exit code.

This changes the output message from e.g.:

    fatal: remote origin already exists.

To:

    error: remote origin already exists.

Which I believe is a feature, since we generally use "fatal" for the
generic errors, and "error" for the more specific ones with a custom
exit code, but this part of the change may break code that already
relies on stderr parsing (not that we ever supported that...).

The motivation for this is a discussion around some code in GitLab's
gitaly which wanted to check this, and had to parse stderr to do so:
https://gitlab.com/gitlab-org/gitaly/-/merge_requests/2695

It's worth noting as an aside that a method of checking this that
doesn't rely on that is to check with "git config" whether the value
in question does or doesn't exist. That introduces a TOCTOU race
condition, but on the other hand this code (e.g. "git remote add")
already has a TOCTOU race.

We go through the config.lock for the actual setting of the config,
but the pseudocode logic is:

    read_config();
    check_config_and_arg_sanity();
    save_config();

So e.g. if a sleep() is added right after the remote_is_configured()
check in add() we'll clobber remote.NAME.url, and add another (usually
duplicate) remote.NAME.fetch entry (and other values, depending on
invocation).

We eventually want to drop the argv_array name and just use strvec
consistently. There's no particular reason we have to do it all at once,
or care about interactions between converted and unconverted bits.
Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).

This patch converts all of the files in builtin/ to keep the diff to a
manageable size.

The conversion was done purely mechanically with:

  git ls-files '*.c' '*.h' |
  xargs perl -i -pe '
    s/ARGV_ARRAY/STRVEC/g;
    s/argv_array/strvec/g;

Denton Liu 203c85339f Use OPT_CALLBACK and OPT_CALLBACK_F
In the codebase, there are many options which use OPTION_CALLBACK in a
plain ol' struct definition. However, we have the OPT_CALLBACK and
OPT_CALLBACK_F macros which are meant to abstract these plain struct
definitions away. These macros are useful as they semantically signal to
developers that these are just normal callback option with nothing fancy
happening.

Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or
OPT_CALLBACK_F where applicable. The heavy lifting was done using the
following (disgusting) shell script:

	#!/bin/sh

	do_replacement () {
		tr '\n' '\r' |
			sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\s*0,\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK(\1,\2,\3,\4,\5,\6)/g' |
			sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK_F(\1,\2,\3,\4,\5,\6,\7)/g' |
			tr '\r' '\n'
	}

	for f in $(git ls-files \*.c)
	do
		do_replacement <"$f" >"$f.tmp"
		mv "$f.tmp" "$f"
	done

The result was manually inspected and then reformatted to match the
style of the surrounding code. Finally, using
`git grep OPTION_CALLBACK \*.c`, leftover results which were not handled
by the script were manually transformed.

Bert Wesarg 88f8576eda pull --rebase/remote rename: document and honor single-letter abbreviations rebase types
When 46af44b07d (pull --rebase=<type>: allow single-letter abbreviations
for the type, 2018-08-04) landed in Git, it had the side effect that
not only 'pull --rebase=<type>' accepted the single-letter abbreviations
but also the 'pull.rebase' and 'branch.<name>.rebase' configurations.

However, 'git remote rename' did not honor these single-letter
abbreviations when reading the 'branch.*.rebase' configurations.

We now document the single-letter abbreviations and both code places
share a common function to parse the values of 'git pull --rebase=*',
'pull.rebase', and 'branches.*.rebase'.

The only functional change is the handling of the `branch_info::rebase`
value. Before it was an unsigned enum, thus the truth value could be
checked with `branch_info::rebase != 0`. But `enum rebase_type` is
signed, thus the truth value must now be checked with
`branch_info::rebase >= REBASE_TRUE`

René Scharfe 99f86bde83 remote: pass NULL to read_ref_full() because object ID is not needed
read_ref_full() wraps refs_read_ref_full(), which in turn wraps
refs_resolve_ref_unsafe(), which handles a NULL oid pointer of callers
not interested in the resolved object ID.  Make use of that feature to
document that mv() is such a caller.

Shulhan 5025425dff builtin/remote: quote remote name on error to display empty name
When adding new remote name with empty string, git will print the
following error message,

  fatal: '' is not a valid remote name\n

But when removing remote name with empty string as input, git shows the
empty string without quote,

  fatal: No such remote: \n

To make these error messages consistent, quote the name of the remote
that we tried and failed to find.

Jeff King 4a7e27e957 convert "oidcmp() == 0" to oideq()
Using the more restrictive oideq() should, in the long run,
give the compiler more opportunities to optimize these
callsites. For now, this conversion should be a complete
noop with respect to the generated code.

The result is also perhaps a little more readable, as it
avoids the "zero is equal" idiom. Since it's so prevalent in
C, I think seasoned programmers tend not to even notice it
anymore, but it can sometimes make for awkward double
negations (e.g., we can drop a few !!oidcmp() instances
here).

This patch was generated almost entirely by the included
coccinelle patch. This mechanical conversion should be
completely safe, because we check explicitly for cases where
oidcmp() is compared to 0, which is what oideq() is doing
under the hood. Note that we don't have to catch "!oidcmp()"
separately; coccinelle's standard isomorphisms make sure the
two are treated equivalently.

I say "almost" because I did hand-edit the coccinelle output
to fix up a few style violations (it mostly keeps the
original formatting, but sometimes unwraps long lines).

René Scharfe fe583c6c7a remote: clear string_list after use in mv()
Switch to the _DUP variant of string_list for remote_branches to allow
string_list_clear() to release the allocated memory at the end, and
actually call that function.  Free the util pointer as well; it is
allocated in read_remote_branches().

NB: This string_list is empty until read_remote_branches() is called
via for_each_ref(), so there is no need to clean it up when returning
before that point.

Derrick Stolee 1d614d41e5 commit-reach: move ref_newer from remote.c
There are several commit walks in the codebase. Group them together into
a new commit-reach.c file and corresponding header. After we group these
walks into one place, we can reduce duplicate logic by calling
equivalent methods.

The ref_newer() method is used by 'git push -f' to check if a force-push
is necessary. By making the method public, we make it possible to test
the method directly without setting up an envieronment where a 'git
push' call makes sense.
