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'

In file included from ./git-compat-util.h:172:0,

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.

A fuzzer running on the entry point provided by fuzz-commit-graph.c
revealed a memory leak when parse_commit_graph() creates a struct
bloom_filter_settings and then returns early due to error. Fix that
error by always freeing that struct first (if it exists) before
returning early due to error.
While making that change, I also noticed another possible memory leak -
when the BLOOMDATA chunk is provided but not BLOOMINDEXES. Also fix that
error.

Commit 9e468334b4 (ref-filter: fallback on alphabetical comparison,
2015-10-30) taught ref-filter's sort to fallback to comparing refnames.
But it did it at the wrong level, overriding the comparison result for a
single "--sort" key from the user, rather than after all sort keys have
been exhausted.
This worked correctly for a single "--sort" option, but not for multiple
ones. We'd break any ties in the first key with the refname and never
evaluate the second key at all.
To make matters even more interesting, we only applied this fallback
sometimes! For a field like "taggeremail" which requires a string
comparison, we'd truly return the result of strcmp(), even if it was 0.
But for numerical "value" fields like "taggerdate", we did apply the
fallback. And that's why our multiple-sort test missed this: it uses
taggeremail as the main comparison.
So let's start by adding a much more rigorous test. We'll have a set of
commits expressing every combination of two tagger emails, dates, and
refnames. Then we can confirm that our sort is applied with the correct
precedence, and we'll be hitting both the string and value comparators.
That does show the bug, and the fix is simple: moving the fallback to
the outer compare_refs() function, after all ref_sorting keys have been
exhausted.
Note that in the outer function we don't have an "ignore_case" flag, as
it's part of each individual ref_sorting element. It's debatable what
such a fallback should do, since we didn't use the user's keys to match.
But until now we have been trying to respect that flag, so the
least-invasive thing is to try to continue to do so. Since all callers
in the current code either set the flag for all keys or for none, we can
just pull the flag from the first key. In a hypothetical world where the
user really can flip the case-insensitivity of keys separately, we may
want to extend the code to distinguish that case from a blanket
"--ignore-case".

All of the ref-filter users (for-each-ref, branch, and tag) take an
--ignore-case option which makes filtering and sorting case-insensitive.
However, this option was applied only to the first element of the
ref_sorting list. So:
git for-each-ref --ignore-case --sort=refname
would do what you expect, but:
git for-each-ref --ignore-case --sort=refname --sort=taggername
would sort the primary key (taggername) case-insensitively, but sort the
refname case-sensitively. We have two options here:
- teach callers to set ignore_case on the whole list
- replace the ref_sorting list with a struct that contains both the
list of sorting keys, as well as options that apply to _all_
keys
I went with the first one here, as it gives more flexibility if we later
want to let the users set the flag per-key (presumably through some
special syntax when defining the key; for now it's all or nothing
through --ignore-case).
The new test covers this by sorting on both tagger and subject
case-insensitively, which should compare "a" and "A" identically, but
still sort them before "b" and "B". We'll break ties by sorting on the
refname to give ourselves a stable output (this is actually supposed to
be done automatically, but there's another bug which will be fixed in
the next commit).

Remove the error condition when updating the sparse-checkout leaves
an empty working directory.
This behavior was added in 9e1afb167 (sparse checkout: inhibit empty
worktree, 2009-08-20). The comment was added in a7bc906f2 (Add
explanation why we do not allow to sparse checkout to empty working
tree, 2011-09-22) in response to a "dubious" comment in 84563a624
(unpack-trees.c: cosmetic fix, 2010-12-22).
With the recent "cone mode" and "git sparse-checkout init [--cone]"
command, it is common to set a reasonable sparse-checkout pattern
set of
/*
!/*/
which matches only files at root. If the repository has no such files,
then their "git sparse-checkout init" command will fail.
Now that we expect this to be a common pattern, we should not have the
commands fail on an empty working directory. If it is a confusing
result, then the user can recover with "git sparse-checkout disable"
or "git sparse-checkout set". This is especially simple when using cone
mode.

The advice to use "$x" rather than "x" in arithmetric expansion was
working around a dash bug fixed in 0.5.4. Even Debian oldstable has
0.5.8 these days. And in the meantime, we've added almost two dozen
instances of the "x" form which you can find with:
git grep '$(([a-z]'
and nobody seems to have complained. Let's declare this workaround
obsolete and simplify our style guide.

With the added checks for invalid URLs in credentials, any locally
modified store files which might have empty lines or even comments
were reported[1] failing to parse as valid credentials.
Instead of doing a hard check for credentials, do a soft one and
therefore avoid the reported fatal error.
While at it add tests for all known corruptions that are currently
ignored to keep track of them and avoid the risk of regressions.

It's typical to find Markdown documentation alongside source code, and
having better context for documentation changes is useful; see also
commit 69f9c87d4 (userdiff: add support for Fountain documents,
2015-07-21).
The pattern is based on the CommonMark specification 0.29, section 4.2
<https://spec.commonmark.org/> but doesn't match empty headings, as
seeing them in a hunk header is unlikely to be useful.
Only ATX headings are supported, as detecting setext headings would
require printing the line before a pattern matches, or matching a
multiline pattern. The word-diff pattern is the same as the pattern for
HTML, because many Markdown parsers accept inline HTML.

There's an example of using your own bit of shell to act as a credential
helper, but it's not very realistic:
- It's stupid to hand out your secret password to _every_ host. In the
real world you'd use the config-matcher to limit it to a particular
host.
- We never provided a username. We can easily do that in another config
option (you can do it in the helper, too, but this is much more
readable).
- We were sending the secret even for store/erase operations. This
is OK because Git would just ignore it, but a real system would
probably be unlocking a password store, which you wouldn't want to do
more than necessary.

We give several helper config examples, but don't make clear that these
are raw values. It's up to the user to add the appropriate quoting to
put them into a config file (either by running with "git config" and
quoting against the shell, or by adding double-quotes as appropriate
within the git-config file).
Let's flesh them out as full config blocks, which makes the syntax more
clear (and makes it possible for people to just cut-and-paste them as a
starting point). I added double-quotes to any values larger than a
single word. That isn't strictly necessary in all cases, but it
sidesteps explaining the rules about exactly when you need to quote a
value.
The existing quotes can be converted to single-quotes in one instance,
and backslash-esccaped in the other. I also swapped out backticks for
our preferred $().

In d787d311db (checkout: split part of it to new command 'switch',
2019-03-29), the `git switch` command was created by extracting the
common functionality of cmd_checkout() in checkout_main(). However, in
b7b5fce270 (switch: better names for -b and -B, 2019-03-29), the branch
creation and force creation options for 'switch' were changed to -c and
-C, respectively. As a result of this, error messages and comments that
previously referred to `-b` and `-B` became invalid for `git switch`.
For error messages that refer to `-b` and `-B`, use a format string
instead so that `-c` and `-C` can be printed when `git switch` is
invoked.
