662f9cf154 (tests: when run in Bash, annotate test failures with file
name/line number, 2020-04-11), introduces a way to report the location
(file:lineno) of a failed test case by traversing the bash callstack.
The implementation requires bash and uses shell arrays and is therefore
protected by a guard but NetBSD sh will still have to parse the function
and therefore will result in:
** t0000-basic.sh ***
./test-lib.sh: 681: Syntax error: Bad substitution
Enclose the bash specific code inside an eval to avoid parsing errors in
the same way than 5826b7b595 (test-lib: check Bash version for '-x'

Depending on the workflows of individual developers, it can either be
convenient or annoying that our GitHub Actions CI jobs are run on every
branch. As an example of annoying: if you carry many half-finished
work-in-progress branches and rebase them frequently against master,
you'd get tons of failure reports that aren't interesting (not to
mention the wasted CPU).
This commit adds a new job which checks a special branch within the
repository for CI config, and then runs a shell script it finds there to
decide whether to skip the rest of the tests. The default will continue
to run tests for all refs if that branch or script is missing.
There have been a few alternatives discussed:
One option is to carry information in the commit itself about whether it
should be tested, either in the tree itself (changing the workflow YAML
file) or in the commit message (a "[skip ci]" flag or similar). But
these are frustrating and error-prone to use:
- you have to manually apply them to each branch that you want to mark
- it's easy for them to leak into other workflows, like emailing patches
We could likewise try to get some information from the branch name. But
that leads to debates about whether the default should be "off" or "on",
and overriding still ends up somewhat awkward. If we default to "on",
you have to remember to name your branches appropriately to skip CI. And
if "off", you end up having to contort your branch names or duplicate
your pushes with an extra refspec.
By comparison, this commit's solution lets you specify your config once
and forget about it, and all of the data is off in its own ref, where it
can be changed by individual forks without touching the main tree.
There were a few design decisions that came out of on-list discussion.
I'll summarize here:
- we could use GitHub's API to retrieve the config ref, rather than a
real checkout (and then just operate on it via some javascript). We
still have to spin up a VM and contact GitHub over the network from
it either way, so it ends up not being much faster. I opted to go
with shell to keep things similar to our other tools (and really
could implement allow-refs in any language you want). This also makes
it easy to test your script locally, and to modify it within the
context of a normal git.git tree.
- we could keep the well-known refname out of refs/heads/ to avoid
cluttering the branch namespace. But that makes it awkward to
manipulate. By contrast, you can just "git checkout ci-config" to
make changes.
- we could assume the ci-config ref has nothing in it except config
(i.e., a branch unrelated to the rest of git.git). But dealing with
orphan branches is awkward. Instead, we'll do our best to efficiently
check out only the ci/config directory using a shallow partial clone,
which allows your ci-config branch to be just a normal branch, with
your config changes on top.
- we could provide a simpler interface, like a static list of ref
patterns. But we can't get out of spinning up a whole VM anyway, so
we might as well use that feature to make the config as flexible as
possible. If we add more config, we should be able to reuse our
partial-clone to set more outputs.

These commands take the --quiet option for their own operation, but
they forget to pass the option down when they invoke "git gc --auto"
internally.

Back in 1991006c (fetch: convert argv_gc_auto to struct argv_array,
2014-08-16), we taught "git fetch --quiet" to pass the "--quiet"
option down to "gc --auto". This issue, however, is not limited to
"fetch":
$ git grep -e 'gc.*--auto' \*.c
finds hits in "am", "commit", "merge", and "rebase" and these
commands do not pass "--quiet" down to "gc --auto" when they
themselves are told to be quiet.
As a preparatory step, let's introduce a helper function
run_auto_gc(), that the caller can pass a boolean "quiet",
and redo the fix to "git fetch" using the helper.

gitcredentials(7) already mentions several possible invocations that one
can use as the value for credential.helper. However, many people are
not aware that there are other options than a simple credential helper
name, so let's place some explanatory text in the documentation for
credential.helper as well.
We still refer the user to gitcredential(7) for additional explanations
and helpful examples.

In documentation pertaining to autostash behavior, we refer to the
"stash reflog". This description is too low-level as the reflog refers
to an implementation detail of how the stash works and, for end-users,
they do not need to be aware of this at all.
Change references of "stash reflog" to "stash list", which should
provide more accessible terminology for end-users.

By default, files are restored from the index for --worktree, and from
HEAD for --staged. When --worktree and --staged are combined, --source
must be specified to disambiguate the restore source[1], thus making it
cumbersome to restore a file in both the worktree and the index.
However, HEAD is also a reasonable default for --worktree when combined
with --staged, so make it the default anytime --staged is used (whether
combined with --worktree or not).
[1]: Due to an oversight, the --source requirement, though documented,
is not actually enforced.

fabec2c5c3 (builtin/receive-pack: switch to use the_hash_algo, 2019-08-18)
renames hmac_sha1 to hmac, as it was updated to use the hash function used
by git (which won't be sha1 in the future).
hmac() is provided by NetBSD >= 8 libc and therefore conflicts as shown by :
builtin/receive-pack.c:421:13: error: conflicting types for 'hmac'
static void hmac(unsigned char *out,
^~~~
In file included from ./git-compat-util.h:172:0,

/usr/include/stdlib.h:305:10: note: previous declaration of 'hmac' was here
ssize_t hmac(const char *, const void *, size_t, const void *, size_t, void *,
^~~~
Rename it again to hmac_hash to reflect it will use the git's defined hash
function and avoid the conflict, while at it update a comment to better
describe the HMAC function that was used.
