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 ce14de03db refs API: remove "failure_errno" from refs_resolve_ref_unsafe()
Remove the now-unused "failure_errno" parameter from the
refs_resolve_ref_unsafe() signature. In my recent 96f6623ada (Merge
branch 'ab/refs-errno-cleanup', 2021-11-29) series we made all of its
callers explicitly request the errno via an output parameter.

As that series shows all but one caller ended up passing in a
boilerplate "ignore_errno", since they only cared about whether the
return value was NULL or not, i.e. if the ref could be resolved.

There was one small issue with that series fixed with a follow-up in
31e3912369 (Merge branch 'ab/refs-errno-cleanup', 2022-01-14) a small
bug in that series was fixed.

After those two there was one caller left in sequencer.c that used the
"failure_errno', but as of the preceding commit it uses a boilerplate
"ignore_errno" instead.

This leaves the public refs API without any use of "failure_errno" at
all. We could still do with a bit of cleanup and generalization
between refs.c and refs/files-backend.c before the "reftable"
integration lands, but that's all internal to the reference code
itself.

So let's remove this output parameter. Not only isn't it used now, but
it's unlikely that we'll want it again in the future. We'd like to
slowly move the refs API to a more file-backend independent way of
communicating error codes, having it use a "failure_errno" was only
the first step in that direction. If this or any other function needs
to communicate what specifically is wrong with the requested "refname"
it'll be better to have the function set some output enum of
well-defined error states than piggy-backend on "errno".

Glen Choo 4a2dcb1a08 remote: die if branch is not found in repository
In a subsequent commit, we would like external-facing functions to be
able to accept "struct repository" and "struct branch" as a pair. This
is useful for functions like pushremote_for_branch(), which need to take
values from the remote_state and branch, even if branch == NULL.
However, a caller may supply an unrelated repository and branch, which
is not supported behavior.

To prevent misuse, add a die_on_missing_branch() helper function that
dies if a given branch is not from a given repository. Speed up the
existence check by replacing the branches list with a branches_hash
hashmap.

Like read_config(), die_on_missing_branch() is only called from
non-static functions; static functions are less prone to misuse because
they have strong conventions for keeping remote_state and branch in
sync.

Glen Choo 56eed3422c remote: remove the_repository->remote_state from static methods
Replace all remaining references of the_repository->remote_state in
static functions with a struct remote_state parameter.

To do so, move read_config() calls to non-static functions and create a
family of static functions, "remotes_*", that behave like "repo_*", but
accept struct remote_state instead of struct repository. In the case
where a static function calls a non-static function, replace the
non-static function with its "remotes_*" equivalent.

Glen Choo 085b98f6cd remote: use remote_state parameter internally
Without changing external-facing functions, replace
the_repository->remote_state internally by adding a struct remote_state
parameter.

As a result, external-facing functions are still tied to the_repository,
but most static functions no longer reference
the_repository->remote_state. The exceptions are those that are used in
a way that depends on external-facing functions e.g. the callbacks to
remote_get_1().

Glen Choo fd3cb0501e remote: move static variables into per-repository struct
remote.c does not works with non-the_repository because it stores its
state as static variables. To support non-the_repository, we can use a
per-repository struct for the remotes subsystem.

Prepare for this change by defining a struct remote_state that holds
the remotes subsystem state and move the static variables of remote.c
into the_repository->remote_state.

This introduces no behavioral or API changes.

Ævar Arnfjörð Bjarmason 9865b6e6a4 *.[ch] *_INIT macros: use { 0 } for a "zero out" idiom
In C it isn't required to specify that all members of a struct are
zero'd out to 0, NULL or '\0', just providing a "{ 0 }" will
accomplish that.

Let's also change code that provided N zero'd fields to just
provide one, and change e.g. "{ NULL }" to "{ 0 }" for
consistency. I.e. even if the first member is a pointer let's use "0"
instead of "NULL". The point of using "0" consistently is to pick one,
and to not have the reader wonder why we're not using the same pattern

Srinidhi Kaushik 99a1f9ae10 push: add reflog check for "--force-if-includes"
Add a check to verify if the remote-tracking ref of the local branch
is reachable from one of its "reflog" entries.

The check iterates through the local ref's reflog to see if there
is an entry for the remote-tracking ref and collecting any commits
that are seen, into a list; the iteration stops if an entry in the
reflog matches the remote ref or if the entry timestamp is older
the latest entry of the remote ref's "reflog". If there wasn't an
entry found for the remote ref, "in_merge_bases_many()" is called
to check if it is reachable from the list of collected commits.

When a local branch that is based on a remote ref, has been rewound
and is to be force pushed on the remote, "--force-if-includes" runs
a check that ensures any updates to the remote-tracking ref that may
have happened (by push from another repository) in-between the time
of the last update to the local branch (via "git-pull", for instance)
and right before the time of push, have been integrated locally
before allowing a forced update.

If the new option is passed without specifying "--force-with-lease",
or specified along with "--force-with-lease=<refname>:<expect>" it
is a "no-op".

Jacob Keller c0192df630 refspec: add support for negative refspecs
Both fetch and push support pattern refspecs which allow fetching or
pushing references that match a specific pattern. Because these patterns
are globs, they have somewhat limited ability to express more complex
situations.

For example, suppose you wish to fetch all branches from a remote except
for a specific one. To allow this, you must setup a set of refspecs
which match only the branches you want. Because refspecs are either
explicit name matches, or simple globs, many patterns cannot be
expressed.

Add support for a new type of refspec, referred to as "negative"
refspecs. These are prefixed with a '^' and mean "exclude any ref
matching this refspec". They can only have one "side" which always
refers to the source. During a fetch, this refers to the name of the ref
on the remote. During a push, this refers to the name of the ref on the
local side.

With negative refspecs, users can express more complex patterns. For
example:

 git fetch origin refs/heads/*:refs/remotes/origin/* ^refs/heads/dontwant

will fetch all branches on origin into remotes/origin, but will exclude
fetching the branch named dontwant.

Refspecs today are commutative, meaning that order doesn't expressly
matter. Rather than forcing an implied order, negative refspecs will
always be applied last. That is, in order to match, a ref must match at
least one positive refspec, and match none of the negative refspecs.
This is similar to how negative pathspecs work.

Jonathan Tan f24c30e0b6 wt-status: tolerate dangling marks
When a user checks out the upstream branch of HEAD, the upstream branch
not being a local branch, and then runs "git status", like this:

  git clone $URL client
  cd client
  git checkout @{u}
  git status

no status is printed, but instead an error message:

  fatal: HEAD does not point to a branch

(This error message when running "git branch" persists even after
checking out other things - it only stops after checking out a branch.)

This is because "git status" reads the reflog when determining the "HEAD
detached" message, and thus attempts to DWIM "@{u}", but that doesn't
work because HEAD no longer points to a branch.

Therefore, when calculating the status of a worktree, tolerate dangling
marks. This is done by adding an additional parameter to
dwim_ref() and repo_dwim_ref().

and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

When guessing the default branch name of a remote, and there are no refs
to guess from, we want to go with the preference specified by the user
for the fall-back, i.e. the default name to be used for the initial

remote that has no branches yet is a new repository).

At the same time, when talking to an older Git server that does not
report a symref for `HEAD` (but instead reports a commit hash), let's
try to guess the configured default branch name first. If it does not
match the reported commit hash, let's fall back to `master` as before.

Jeff King f5914f4b6b parse_config_key(): return subsection len as size_t
We return the length to a subset of a string using an "int *"
out-parameter. This is fine most of the time, as we'd expect config keys
to be relatively short, but it could behave oddly if we had a gigantic
config key. A more appropriate type is size_t.

Let's switch over, which lets our callers use size_t as appropriate
(they are bound by our type because they must pass the out-parameter as
a pointer). This is mostly just a cleanup to make it clear this code
handles long strings correctly. In practice, our config parser already
chokes on long key names (because of a similar int/size_t mixup!).

When doing an int/size_t conversion, we have to be careful that nobody
was trying to assign a negative value to the variable. I manually
confirmed that for each case here. They tend to just feed the result to
xmemdupz() or similar; in a few cases I adjusted the parameter types for
helper functions to make sure the size_t is preserved.

Jeff King 021ba32a7b remote: drop auto-strlen behavior of make_branch() and make_rewrite()
The make_branch() and make_rewrite() functions can take a NUL-terminated
string or a ptr/len pair. They use a sentinel value of "0" for the len
to tell the difference between the two. However, when parsing config
like:

  [branch ""]
  merge = whatever

whose key flattens to:

  branch..merge

we might actually have a zero-length branch name. This is obviously
nonsense, but the current code would consider it as a NUL-terminated
string and use the branch name ".merge".

We could use a better sentinel value here (like "-1"), but that gets in
the way of moving to size_t, which is a more appropriate type for a
ptr/len combo.

Let's instead just drop this feature and have the callers (of which
there are only two total) use strlen() themselves. This simplifies the
code, and lets us move to using size_t.

ref name, 2017-11-07) added a remote_ref_for_branch() helper, which
is modeled after remote_for_branch(). This includes providing an
"explicit" out-parameter that tells the caller whether the remote
was configured by the user, or whether we picked a default name like
"origin".

But unlike remote names, there is no default name when the user
didn't configure one.  The only way the "explicit" parameter is used
by the caller is to use the value returned from the helper when it
is set, and use an empty string otherwise, ignoring the returned
value from the helper.

Let's drop the "explicit" out-parameter, and return NULL when the
returned value from the helper should be ignored, to simplify the
function interface.

Matthew Rogers 6dc905d974 config: split repo scope to local and worktree
Previously when iterating through git config variables, worktree config
and local config were both considered "CONFIG_SCOPE_REPO".  This was
never a problem before as no one had needed to differentiate between the
two cases, but future functionality may care whether or not the config
options come from a worktree or from the repository's actual local
config file.  For example, the planned feature to add a '--show-scope'
to config to allow a user to see which scope listed config options come
from would confuse users if it just printed 'repo' rather than 'local'
or 'worktree' as the documentation would lead them to expect.  As well
as the additional benefit of making the implementation look more like
how the documentation describes the interface.

To accomplish this we split out what was previously considered repo
scope to be local and worktree.

The clients of 'current_config_scope()' who cared about
CONFIG_SCOPE_REPO are also modified to similarly care about
CONFIG_SCOPE_WORKTREE and CONFIG_SCOPE_LOCAL to preserve previous behavior.

Eric Wong 404ab78e39 hashmap: remove type arg from hashmap_{get,put,remove}_entry
Since these macros already take a `keyvar' pointer of a known type,
we can rely on OFFSETOF_VAR to get the correct offset without
relying on non-portable `__typeof__' and `offsetof'.

Argument order is also rearranged, so `keyvar' and `member' are
sequential as they are used as: `keyvar->member'

  ref-filter: use correct branch for %(push:track)
2019-05-09 00:37:26 +09:00
Damien Robert c646d0934e ref-filter: use correct branch for %(push:track)
In ref-filter.c, when processing the atom %(push:track), the
ahead/behind values are computed using `stat_tracking_info` which refers
to the upstream branch.

Fix that by introducing a new flag `for_push` in `stat_tracking_info`
in remote.c, which does the same thing but for the push branch.
Update the few callers of `stat_tracking_info` to handle this flag. This
ensure that whenever we use this function in the future, we are careful
to specify is this should apply to the upstream or the push branch.

This bug was not detected in t/t6300-for-each-ref.sh because in the test
for push:track, both the upstream and the push branches were behind by 1
from the local branch. Change the test so that the upstream branch is
behind by 1 while the push branch is ahead by 1. This allows us to test
that %(push:track) refers to the correct branch.

This changes the expected value of some following tests (by introducing
new references), so update them too.

Jeff King 1027186fdd remote.c: make singular free_ref() public
We provide a free_refs() function to free a list, but there's no easy
way for a caller to free a single ref. Let's make our singular
free_ref() function public. Since its name is so similar to the
list-freeing free_refs(), and because both of those functions have the
same signature, it might be easy to accidentally use the wrong one.
Let's call the singular version the more verbose "free_one_ref()" to
distinguish it.

Jeff King 54e8c11215 remote: check config validity before creating rewrite struct
When parsing url.foo.insteadOf, we call make_rewrite() and only then
check to make sure the config value is a string (and return an error if
it isn't). This isn't quite a leak, because the struct we allocate is
part of a global array, but it does leave a funny half-finished struct.

In practice, it doesn't make much difference because we exit soon after
due to the config error anyway. But let's flip the order here to avoid
leaving a trap for somebody in the future.
