Our users are going to be trained to prepare for future change of
init.defaultBranch configuration variable.
* js/init-defaultbranch-advice:
init: provide useful advice about init.defaultBranch
get_default_branch_name(): prepare for showing some advice
branch -m: allow renaming a yet-unborn branch
init: document `init.defaultBranch` better

Style fix.
* jk/multi-line-indent-style-fix:

We are about to introduce a message giving users running `git init` some
advice about `init.defaultBranch`. This will necessarily be done in
`repo_default_branch_name()`.
Not all code paths want to show that advice, though. In particular, the
`git clone` codepath _specifically_ asks for `init_db()` to be quiet,
via the `INIT_DB_QUIET` flag.
In preparation for showing users above-mentioned advice, let's change
the function signature of `get_default_branch_name()` to accept the
parameter `quiet`.

"git push --force-with-lease[=<ref>]" can easily be misused to lose
commits unless the user takes good care of their own "git fetch".
A new option "--force-if-includes" attempts to ensure that what is
being force-pushed was created after examining the commit at the
tip of the remote ref that is about to be force-replaced.
* sk/force-if-includes:

"git fetch" and "git push" support negative refspecs.
* jk/refspecs-negative:
refspec: add support for negative refspecs
|

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".

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.

"git status" has trouble showing where it came from by interpreting
reflog entries that recordcertain events, e.g. "checkout @{u}", and
gives a hard/fatal error. Even though it inherently is impossible
to give a correct answer because the reflog entries lose some
information (e.g. "@{u}" does not record what branch the user was
on hence which branch 'the upstream' needs to be computed, and even
if the record were available, the relationship between branches may
have changed), at least hide the error to allow "status" show its
output.

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().

The "argc" and "argv" names made sense when the struct was argv_array,
but now they're just confusing. Let's rename them to "nr" (which we use
for counts elsewhere) and "v" (which is rather terse, but reads well
when combined with typical variable names like "args.v").
Note that we have to update all of the callers immediately. Playing
tricks with the preprocessor is hard here, because we wouldn't want to
rewrite unrelated tokens.

Code which split an argv_array call across multiple lines, like:
argv_array_pushl(&args, "one argument",
"another argument", "and more",
NULL);
was recently mechanically renamed to use strvec, which results in
mis-matched indentation like:
strvec_pushl(&args, "one argument",
"another argument", "and more",
NULL);
Let's fix these up to align the arguments with the opening paren. I did
this manually by sifting through the results of:
git jump grep 'strvec_.*,$'
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.

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 remaining files, as the resulting diff is
reasonably sized.
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;
'
We'll deal with any indentation/style fallouts separately.

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
branch of new repositories (because as far as the user is concerned, a
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.

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.

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.

Commit 9700fae5ee (for-each-ref: let upstream/push report the remote
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.

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.

%(push:track) token used in the --format option to "git
for-each-ref" and friends was not showing the right branch, which
has been fixed.
* dr/ref-filter-push-track-fix:
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.

free_ref() function public. Since its name is so similar to the

change looks like this:
$ git push avar v2.19.0^{commit}:newbranch -n

The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.

error: failed to push some refs to 'git@github.com:avar/git.git'
This improvement is the result of on-list discussion in [1] and [2],

The suggestion by Jeff on-list was to make that second bullet point
"Looking at the refname of the local source.". The version being added
here is more verbose, but also more accurate. saying "local source"
could refer to any ref in the local refstore, including something in
refs/remotes/*. A later change will teach guess_ref() to infer a ref
type from remote-tracking refs, so let's not confuse the two.
While I'm at it, add a "TRANSLATORS" comment since the message has
gotten more complex and it's not as clear what the two %s's refer to.

The add_missing_tags() method currently has quadratic behavior.
This is due to a linear number (based on number of tags T) of

Replace this O(T * C) algorithm with an O(T + C) algorithm by

spatch transformation to replace boolean uses of !hashcmp() to
newly introduced oideq() is added, and applied, to regain
performance lost due to support of multiple hash algorithms.
* jk/cocci:
show_dirstat: simplify same-content check
read-cache: use oideq() in ce_compare functions
convert hashmap comparison functions to oideq()
convert "hashcmp() != 0" to "!hasheq()"
convert "oidcmp() != 0" to "!oideq()"
convert "hashcmp() == 0" to hasheq()
convert "oidcmp() == 0" to oideq()
introduce hasheq() and oideq()
coccinelle: use <...> for function exclusion

The code for computing history reachability has been shuffled,
obtained a bunch of new tests to cover them, and then being
improved.
* ds/reachable:
commit-reach: correct accidental #include of C file
commit-reach: use can_all_from_reach
commit-reach: make can_all_from_reach... linear
commit-reach: replace ref_newer logic
test-reach: test commit_contains
test-reach: test can_all_from_reach_with_flags
test-reach: test reduce_heads
test-reach: test get_merge_bases_many
test-reach: test is_descendant_of
test-reach: test in_merge_bases
test-reach: create new test tool for ref_newer
commit-reach: move can_all_from_reach_with_flags
upload-pack: generalize commit date cutoff
upload-pack: refactor ok_to_give_up()
upload-pack: make reachable() more generic
commit-reach: move commit_contains from ref-filter
commit-reach: move ref_newer from remote.c
commit.h: remove method declarations
commit-reach: move walk methods from commit.c

This is the flip side of the previous two patches: checking
for a non-zero oidcmp() can be more strictly expressed as
inequality. Like those patches, we write "!= 0" in the
coccinelle transformation, which covers by isomorphism the
more common:
if (oidcmp(E1, E2))
As with the previous two patches, this patch can be achieved
almost entirely by running "make coccicheck"; the only
differences are manual line-wrap fixes to match the original
code.
There is one thing to note for anybody replicating this,
though: coccinelle 1.0.4 seems to miss the case in
builtin/tag.c, even though it's basically the same as all
the others. Running with 1.0.7 does catch this, so
presumably it's just a coccinelle bug that was fixed in the
interim.

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).

"git fetch $there refs/heads/s" ought to fetch the tip of the
branch 's', but when "refs/heads/refs/heads/s", i.e. a branch whose
name is "refs/heads/s" exists at the same time, fetched that one
instead by mistake. This has been corrected to honor the usual
disambiguation rules for abbreviated refnames.
* jt/refspec-dwim-precedence-fix:
remote: make refspec follow the same disambiguation rule as local refs
