A new warning message is issued when a command has to expand a
sparse index to handle working tree cruft that are outside of the
sparse checkout.
* ds/advice-sparse-index-expansion:
advice: warn when sparse index expands
Typically, forcing a sparse index to expand to a full index means that
Git could not determine the status of a file outside of the
sparse-checkout and needed to expand sparse trees into the full list of
sparse blobs. This operation can be very slow when the sparse-checkout
is much smaller than the full tree at HEAD.
When users are in this state, there is usually a modified or untracked
file outside of the sparse-checkout mentioned by the output of 'git
status'. There are a number of reasons why this is insufficient:
1. Users may not have a full understanding of which files are inside or
outside of their sparse-checkout. This is more common in monorepos
that manage the sparse-checkout using custom tools that map build
dependencies into sparse-checkout definitions.
2. In some cases, an empty directory could exist outside the
sparse-checkout and these empty directories are not reported by 'git
status' and friends.
3. If the user has '.gitignore' or 'exclude' files, then 'git status'
will squelch the warnings and not demonstrate any problems.
In order to help users who are in this state, add a new advice message
to indicate that a sparse index is expanded to a full index. This
message should be written at most once per process, so add a static
global 'give_advice_on_expansion' to sparse-index.c. Further, there is a
case in 'git sparse-checkout set' that uses the sparse index as an
in-memory data structure (even when writing a full index) so we need to
disable the message in that kind of case.
The t1092-sparse-checkout-compatibility.sh test script compares the
behavior of several Git commands across full and sparse repositories,
including sparse repositories with and without a sparse index. We need
to disable the advice in the sparse-index repo to avoid differences in
stderr. By leaving the advice on in the sparse-checkout repo (without
the sparse index), we can test the behavior of disabling the advice in
convert_to_sparse(). (Indeed, these tests are how that necessity was
discovered.) Add a test that reenables the advice and demonstrates that
the message is output.
The advice message is defined outside of expand_index() to avoid super-
wide lines. It is also defined as a macro to avoid compile issues with
-Werror=format-security.

The only todo commands that accept a merge commit are "merge" and
"reset". All the other commands like "pick" or "reword" fail when they
try to pick a a merge commit and print the message
error: commit abc123 is a merge but no -m option was given.
followed by a hint about the command being rescheduled. This message is
designed to help the user when they cherry-pick a merge and forget to
pass "-m". For users who are rebasing the message is confusing as there
is no way for rebase to cherry-pick the merge.
Improve the user experience by detecting the error and printing some
advice on how to fix it when the todo list is parsed rather than waiting
for the "pick" command to fail. The advice recommends "merge" rather
than "exec git cherry-pick -m ..." on the assumption that cherry-picking
merges is relatively rare and it is more likely that the user chose
"pick" by a mistake.
It would be possible to support cherry-picking merges by allowing the
user to pass "-m" to "pick" commands but that adds complexity to do
something that can already be achieved with
exec git cherry-pick -m1 abc123

Allow disabling the advice shown when a squencer operation results in a
merge conflict through a new config 'advice.mergeConflict', which is
named generically such that it can be used by other commands eventually.
Remove that final '\n' in the first hunk in sequencer.c to avoid an
otherwise empty 'hint: ' line before the line 'hint: Disable this
message with "git config advice.mergeConflict false"' which is
automatically added by 'advise_if_enabled'.
Note that we use 'advise_if_enabled' for each message in the second hunk
in sequencer.c, instead of using 'if (show_hints &&
advice_enabled(...)', because the former instructs the user how to
disable the advice, which is more user-friendly.
Update the tests accordingly. Note that the body of the second test in
t3507-cherry-pick-conflict.sh is enclosed in double quotes, so we must
escape them in the added line. Note that t5520-pull.sh, which checks
that we display the advice for 'git rebase' (via 'git pull --rebase')
does not have to be updated because it only greps for a specific line in
the advice message.

When git refuses to create a branch because the proposed branch

the user to exact naming rules.
* kh/branch-ref-syntax-advice:
branch: advise about ref syntax rules
advice: use double quotes for regular quoting

git-branch(1) will error out if you give it a bad ref name. But the user
might not understand why or what part of the name is illegal.
The user might know that there are some limitations based on the *loose
ref* format (filenames), but there are also further rules for
easier integration with shell-based tools, pathname expansion, and
playing well with reference name expressions.
The man page for git-check-ref-format(1) contains these rules. Let’s
advise about it since that is not a command that you just happen
upon. Also make this advise configurable since you might not want to be

For sanity, we should probably do one of the following:
(a) make C and header files both depend upon everything they need
(b) consistently exclude git-compat-util.h from headers and require it
be the first include in C files
Currently, we have some of the headers following (a) and others
following (b), which makes things messy. In the past I was pushed
towards (b), as per [1] and [2]. Further, during this series I
discovered that this mixture empirically will mean that we end up with C
files that do not directly include git-compat-util.h, and do include
headers that don't include git-compat-util.h, with the result that we
likely have headers included before an indirect inclusion of
git-compat-util.h. Since git-compat-util.h has tricky platform-specific
stuff that is meant to be included before everything else, this state of
affairs is risky and may lead to things breaking in subtle ways (and
only on some platforms) as per [1] and [2].
Since including git-compat-util.h in existing header files makes it
harder for us to catch C files that are missing that include, let's
switch to (b) to make the enforcement of this rule easier. Remove the
inclusion of git-compat-util.h from header files other than the ones
that have been approved as alternate first includes.

To improve the submodules UX, we would like to teach Git to handle
branches in submodules. Start this process by teaching "git branch" the
--recurse-submodules option so that "git branch --recurse-submodules
topic" will create the `topic` branch in the superproject and its
submodules.
Although this commit does not introduce breaking changes, it does not
work well with existing --recurse-submodules commands because "git
branch --recurse-submodules" writes to the submodule ref store, but most
commands only consider the superproject gitlink and ignore the submodule
ref store. For example, "git checkout --recurse-submodules" will check
out the commits in the superproject gitlinks (and put the submodules in
detached HEAD) instead of checking out the submodule branches.
Because of this, this commit introduces a new configuration value,
`submodule.propagateBranches`. The plan is for Git commands to
prioritize submodule ref store information over superproject gitlinks if
this value is true. Because "git branch --recurse-submodules" writes to
submodule ref stores, for the sake of clarity, it will not function
unless this configuration value is set.
This commit also includes changes that support working with submodules
from a superproject commit because "branch --recurse-submodules" (and
future commands) need to read .gitmodules and gitlinks from the
superproject commit, but submodules are typically read from the
filesystem's .gitmodules and the index's gitlinks. These changes are:
* add a submodules_of_tree() helper that gives the relevant
information of an in-tree submodule (e.g. path and oid) and
initializes the repository
* add is_tree_submodule_active() by adding a treeish_name parameter to
is_submodule_active()
* add the "submoduleNotUpdated" advice to advise users to update the
submodules in their trees
Incidentally, fix an incorrect usage string that combined the 'list'
usage of git branch (-l) with the 'create' usage; this string has been
incorrect since its inception, a8dfd5eac4 (Make builtin-branch.c use
parse_options., 2007-10-07).

The --[no-]show-forced-updates option in 'git fetch' can be confusing
for some users, especially if it is enabled via config setting and not
by argument. Add advice to warn the user that the (forced update)
messages were not listed.
Additionally, warn users when the forced update check takes longer
than ten seconds, and recommend that they disable the check. These
messages can be disabled by the advice.fetchShowForcedUpdates config
setting.

The ahead/behind calculation in 'git status' can be slow in some
cases. Users may not realize that there are ways to avoid this
computation, especially if they are not using the information.
Add a warning that appears if this calculation takes more than
two seconds. The warning can be disabled through the new config
setting advice.statusAheadBehind.

Mechanically and systematically drop "extern" from function
declarlation.
* dl/no-extern-in-func-decl:
*.[ch]: manually align parameter lists
*.[ch]: remove extern from function declarations using sed
*.[ch]: remove extern from function declarations using spatch
There has been a push to remove extern from function declarations.
Remove some instances of "extern" for function declarations which are
caught by Coccinelle. Note that Coccinelle has some difficulty with
processing functions with `__attribute__` or varargs so some `extern`
declarations are left behind to be dealt with in a future patch.
This was the Coccinelle patch used:
@@
type T;
identifier f;
@@
- extern
T f(...);
and it was run with:
$ git ls-files \*.{c,h} |
grep -v ^compat/ |
xargs spatch --sp-file contrib/coccinelle/noextern.cocci --in-place
Files under `compat/` are intentionally excluded as some are directly
copied from external sources and we should avoid churning them as much
as possible.

Robert Dailey reported confusion on the mailing list about a nested
tag which was most likely created by mistake. Jeff King noted that
this isn't a very common case and creating a tag-to-a-tag can be a
user-error.
Suggest that it may be a mistake with an advice message when
creating such a tag. Those who do want to create a tag that point
at another tag regularly can turn it off with the usual advice
mechanism.

Add an advice to the recently improved error message added in
f8aae12034 ("push: allow unqualified dest refspecs to DWIM",
2008-04-23).
Now with advice.pushUnqualifiedRefName=true (on by default) we show a
hint about how to proceed:
$ ./git-push avar v2.19.0^{commit}:newbranch -n
error: The destination you provided is not a full refname (i.e.,
starting with "refs/"). We tried to guess what you meant by:
- Looking for a ref that matches 'newbranch' on the remote side.
- Checking if the <src> being pushed ('v2.19.0^{commit}')
is a ref in "refs/{heads,tags}/". If so we add a corresponding
refs/{heads,tags}/ prefix on the remote side.
Neither worked, so we gave up. You must fully qualify the ref.
hint: The <src> part of the refspec is a commit object.
hint: Did you mean to create a new branch by pushing to
hint: 'v2.19.0^{commit}:refs/heads/newbranch'?
error: failed to push some refs to 'git@github.com:avar/git.git'
When trying to push a tag, tree or a blob we suggest that perhaps the
user meant to push them to refs/tags/ instead.
The if/else duplication for all of OBJ_{COMMIT,TAG,TREE,BLOB} is
unfortunate, but is required to correctly mark the messages for
translation. See the discussion in
<87r2gxebsi.fsf@evledraar.gmail.com> about that.

refresh_index() is done after a reset command as an optimization. Because
it can be an expensive call, warn the user if it takes more than 2 seconds
and tell them how to avoid it using the --quiet command line option or
reset.quiet config setting.

"git checkout" and "git worktree add" learned to honor
checkout.defaultRemote when auto-vivifying a local branch out of a
remote tracking branch in a repository with multiple remotes that
have tracking branches that share the same names.
* ab/checkout-default-remote:
checkout & worktree: introduce checkout.defaultRemote
checkout: add advice for ambiguous "checkout <branch>"
builtin/checkout.c: use "ret" variable for return
checkout: pass the "num_matches" up to callers
checkout.c: change "unique" member to "num_matches"
checkout.c: introduce an *_INIT macro
checkout.h: wrap the arguments to unique_tracking_name()
checkout tests: index should be clean after dwim checkout
As the "checkout" documentation describes:
If <branch> is not found but there does exist a tracking branch in
exactly one remote (call it <remote>) with a matching name, treat
as equivalent to [...] <remote>/<branch.
This is a really useful feature. The problem is that when you add
another remote (e.g. a fork), git won't find a unique branch name
anymore, and will instead print this unhelpful message:
$ git checkout master
error: pathspec 'master' did not match any file(s) known to git
Now it will, on my git.git checkout, print:
$ ./git --exec-path=$PWD checkout master
error: pathspec 'master' did not match any file(s) known to git.
hint: 'master' matched more than one remote tracking branch.
hint: We found 26 remotes with a reference that matched. So we fell back
hint: on trying to resolve the argument as a path, but failed there too!
hint:
hint: If you meant to check out a remote tracking branch on, e.g. 'origin',
hint: you can do so by fully qualifying the name with the --track option:
hint:
hint: git checkout --track origin/<name>
Note that the "error: pathspec[...]" message is still printed. This is
because whatever else checkout may have tried earlier, its final
fallback is to try to resolve the argument as a path. E.g. in this
case:
$ ./git --exec-path=$PWD checkout master pu
error: pathspec 'master' did not match any file(s) known to git.
error: pathspec 'pu' did not match any file(s) known to git.
There we don't print the "hint:" implicitly due to earlier logic
around the DWIM fallback. That fallback is only used if it looks like
we have one argument that might be a branch.
I can't think of an intrinsic reason for why we couldn't in some
future change skip printing the "error: pathspec[...]" error. However,
to do so we'd need to pass something down to checkout_paths() to make
it suppress printing an error on its own, and for us to be confident
that we're not silencing cases where those errors are meaningful.
I don't think that's worth it since determining whether that's the
case could easily change due to future changes in the checkout logic.
