Jeff King 37e8a341ea push: drop confusing configset/callback redundancy
We parse push config by calling git_config() with our git_push_config()
callback. But inside that callback, when we see "push.gpgsign", we
ignore the value passed into the callback and instead make a new call to
git_config_get_value().

This is unnecessary at best, and slightly wrong at worst (if there are
multiple instances, get_value() only returns one; both methods end up
with last-one-wins, but we'd fail to report errors if earlier
incarnations were bogus).

The call was added by 68c757f219 (push: add a config option push.gpgSign
for default signed pushes, 2015-08-19). That commit doesn't give any
reason to deviate from the usual strategy here; it was probably just
somebody unfamiliar with our config API and its conventions.

It also added identical code to builtin/send-pack.c, which also handles
push.gpgsign.

And then the same issue spread to its neighbor in b33a15b081 (push: add
recurseSubmodules config option, 2015-11-17), presumably via
cargo-culting.

This patch fixes all three to just directly use the value provided to
the callback. While I was adjusting the code to do so, I noticed that
push.gpgsign is overly careful about a NULL value. After
git_parse_maybe_bool() has returned anything besides 1, we know that the
value cannot be NULL (if it were, it would be an implicit "true", and
many callers of maybe_bool rely on that). Here that lets us shorten "if
(v && !strcasecmp(v, ...))" to just "if (!strcasecmp(v, ...))".

Jeff King d49cb162fa fsck: handle NULL value when parsing message config
When parsing fsck.*, receive.fsck.*, or fetch.fsck.*, we don't check for
an implicit bool. So any of:

  [fsck]
  badTree
  [receive "fsck"]
  badTree
  [fetch "fsck"]
  badTree

will cause us to segfault. We can fix it with config_error_nonbool() in
the usual way, but we have to make a few more changes to get good error
messages. The problem is that all three spots do:

  if (skip_prefix(var, "fsck.", &var))

to match and parse the actual message id. But that means that "var" now
just says "badTree" instead of "receive.fsck.badTree", making the
resulting message confusing. We can fix that by storing the parsed
message id in its own separate variable.

Jeff King ba176db511 config: handle NULL value when parsing non-bools
When the config parser sees an "implicit" bool like:

  [core]
  someVariable

it passes NULL to the config callback. Any callback code which expects a
string must check for NULL. This usually happens via helpers like
git_config_string(), etc, but some custom code forgets to do so and will
segfault.

These are all fairly vanilla cases where the solution is just the usual
pattern of:

  if (!value)
        return config_error_nonbool(var);

though note that in a few cases we have to split initializers like:

  int some_var = initializer();

into:

  int some_var;
  if (!value)
        return config_error_nonbool(var);
  some_var = initializer();

There are still some broken instances after this patch, which I'll
address on their own in individual patches after this one.

Jeff King daaa03e54c bisect: always clean on reset
Usually "bisect reset" cleans up any refs/bisect/ refs, along with
meta-files like .git/BISECT_LOG. But it only does so after deciding that
a bisection is active, which it does by reading BISECT_START. This is
usually fine, but it's possible to get into a confusing state if the
BISECT_START file is gone, but other cruft is left (this might be due to
a bug, or a system crash, etc).

And since "bisect reset" refuses to do anything in this state, the user
has no easy way to clean up the leftover cruft. While another "bisect
start" would clear the state, in the interim it can be annoying, as
other tools (like our bash prompt code) think we are bisecting, and
for-each-ref output may be polluted with refs/bisect/ entries.

Further adding to the confusion is that running "bisect reset $some_ref"
skips the BISECT_START check. So it never realizes that there's no
bisection active and does the cleanup anyway!

So let's just make sure we always do the cleanup, whether we looked at
BISECT_START or not. If the user doesn't give us a commit to reset to,
we'll still say "We are not bisecting" and skip the call to "git
checkout".

René Scharfe 792b86283b worktree: simplify incompatibility message for --orphan and commit-ish
Use a single translatable string to report that the worktree add option
--orphan is incompatible with a commit-ish instead of having the
commit-ish in a separate translatable string.  This reduces the number
of strings to translate and gives translators the full context.

A similar message is used in builtin/describe.c, but with the plural of
commit-ish, and here we need the singular form.

Elijah Newren e928c11e29 replay: stop assuming replayed branches do not diverge
The replay command is able to replay multiple branches but when some of
them are based on other replayed branches, their commit should be
replayed onto already replayed commits.

For this purpose, let's store the replayed commit and its original
commit in a key value store, so that we can easily find and reuse a
replayed commit instead of the original one.

Elijah Newren 3916ec307e replay: use standard revision ranges
Instead of the fixed "<oldbase> <branch>" arguments, the replay
command now accepts "<revision-range>..." arguments in a similar
way as many other Git commands. This makes its interface more
standard and more flexible.

This also enables many revision related options accepted and
eaten by setup_revisions(). If the replay command was a high level
one or had a high level mode, it would make sense to restrict some
of the possible options, like those generating non-contiguous
history, as they could be confusing for most users.

Also as the interface of the command is now mostly finalized,
we can add more documentation and more testcases to make sure
the command will continue to work as designed in the future.

We only document the rev-list related options among all the
revision related options that are now accepted, as the rev-list
related ones are probably the most useful for now.

Elijah Newren 81613be31e replay: make it a minimal server side command
We want this command to be a minimal command that just does server side
picking of commits, displaying the results on stdout for higher level
scripts to consume.

So let's simplify it:
  * remove the worktree and index reading/writing,
  * remove the ref (and reflog) updating,
  * remove the assumptions tying us to HEAD, since (a) this is not a
    rebase and (b) we want to be able to pick commits in a bare repo,
    i.e. to/from branches that are not checked out and not the main
    branch,
  * remove unneeded includes,
  * handle rebasing multiple branches by printing on stdout the update
    ref commands that should be performed.

The output can be piped into `git update-ref --stdin` for the ref
updates to happen.

In the future to make it easier for users to use this command
directly maybe an option can be added to automatically pipe its output
into `git update-ref`.

Let's force the rev walking options we need after calling
setup_revisions() instead of before.

This might override some user supplied rev walking command line options
though. So let's detect that and warn users by:

  a) setting the desired values, before setup_revisions(),
  b) checking after setup_revisions() whether these values differ from
     the desired values,
  c) if so throwing a warning and setting the desired values again.

We want the command to work from older commits to newer ones by default.
Also we don't want history simplification, as we want to deal with all
the commits in the affected range.

Instead of manually parsing arguments, let's start using the parse_options

Note that we plan to later use standard revision ranges instead of

arguments if we keep ARGV[0], so let's call parse_options() with
PARSE_OPT_KEEP_ARGV0 even if we don't need ARGV[0] right now to avoid
some useless code churn.

Elijah Newren f920b0289b replay: introduce new builtin
For now, this is just a rename from `t/helper/test-fast-rebase.c` into
`builtin/replay.c` with minimal changes to make it build appropriately.

Let's add a stub documentation and a stub test script though.

Subsequent commits will flesh out the capabilities of the new command
and make it a more standard regular builtin.

Josh Brobst cbf498eb53 builtin/reflog.c: fix dry-run option short name
The documentation for reflog states that the --dry-run option of the
expire and delete subcommands has a corresponding short name, -n.
However, 33d7bdd645 (builtin/reflog.c: use parse-options api for expire,
delete subcommands, 2022-01-06) did not include this short name in the
new options parsing.

Re-add the short name in the new dry-run option definitions.

Make it possible to use other diff algorithms than the 'myers'
default algorithm, when using the 'git merge-file' command, to help
avoid spurious conflicts by selecting a more recent algorithm such
as 'histogram', for instance when using 'git merge-file' as part of

Victoria Dye e7574b0c6b ref-filter.h: add functions for filter/format & format-only
Add two new public methods to 'ref-filter.h':

* 'print_formatted_ref_array()' which, given a format specification & array
  of ref items, formats and prints the items to stdout.
* 'filter_and_format_refs()' which combines 'filter_refs()',
  'ref_array_sort()', and 'print_formatted_ref_array()' into a single
  function.

This consolidates much of the code used to filter and format refs in
'builtin/for-each-ref.c', 'builtin/tag.c', and 'builtin/branch.c', reducing
duplication and simplifying the future changes needed to optimize the filter
& format process.

Victoria Dye 9d4fcfe1ff ref-filter.h: add max_count and omit_empty to ref_format
Add an internal 'array_opts' struct to 'struct ref_format' containing
formatting options that pertain to the formatting of an entire ref array:
'max_count' and 'omit_empty'. These values are specified by the '--count'
and '--omit-empty' options, respectively, to 'for-each-ref'/'tag'/'branch'.
Storing these values in the 'ref_format' will simplify the consolidation of
ref array formatting logic across builtins in later patches.

Victoria Dye 56d26ade97 ref-filter.c: really don't sort when using --no-sort
When '--no-sort' is passed to 'for-each-ref', 'tag', and 'branch', the
printed refs are still sorted by ascending refname. Change the handling of
sort options in these commands so that '--no-sort' to truly disables
sorting.

'--no-sort' does not disable sorting in these commands is because their
option parsing does not distinguish between "the absence of '--sort'"
(and/or values for tag.sort & branch.sort) and '--no-sort'. Both result in
an empty 'sorting_options' string list, which is parsed by
'ref_sorting_options()' to create the 'struct ref_sorting *' for the
command. If the string list is empty, 'ref_sorting_options()' interprets
that as "the absence of '--sort'" and returns the default ref sorting
structure (equivalent to "refname" sort).

To handle '--no-sort' properly while preserving the "refname" sort in the
"absence of --sort'" case, first explicitly add "refname" to the string list
*before* parsing options. This alone doesn't actually change any behavior,
since 'compare_refs()' already falls back on comparing refnames if two refs
are equal w.r.t all other sort keys.

Now that the string list is populated by default, '--no-sort' is the only
way to empty the 'sorting_options' string list. Update
'ref_sorting_options()' to return a NULL 'struct ref_sorting *' if the
string list is empty, and add a condition to 'ref_array_sort()' to skip the
sort altogether if the sort structure is NULL. Note that other functions
using 'struct ref_sorting *' do not need any changes because they already
ignore NULL values.

Finally, remove the condition around sorting in 'ls-remote', since it's no
longer necessary. Unlike 'for-each-ref' et. al., it does *not* do any
sorting by default. This default is preserved by simply leaving its sort key
string list empty before parsing options; if no additional sort keys are
set, 'struct ref_sorting *' is NULL and sorting is skipped.

Andy Koppe 297be59456 rebase: support --autosquash without -i
The rebase --autosquash option is quietly ignored when used without
--interactive (apart from preventing preemptive fast-forwarding and
triggering conflicts with apply backend options).

Change that to support --autosquash without --interactive, by dropping
its restriction to REBASE_INTERACTIVE_EXCPLICIT mode. When used this
way, auto-squashing is done without opening the todo list editor.

Drop the -i requirement from the --autosquash description, and amend
t3415-rebase-autosquash.sh to test the option and the rebase.autoSquash
config variable with and without -i.

Andy Koppe 75cf39b117 rebase: fully ignore rebase.autoSquash without -i
Setting the rebase.autoSquash config variable to true implies a couple
of restrictions: it prevents preemptive fast-forwarding and it triggers
conflicts with apply backend options. However, it only actually results
in auto-squashing when combined with the --interactive (or -i) option,
due to code in run_specific_rebase() that disables auto-squashing unless
the REBASE_INTERACTIVE_EXPLICIT flag is set.

Doing autosquashing for rebase.autoSquash without --interactive would be
problematic in terms of backward compatibility, but conversely, there is
no need for the aforementioned restrictions without --interactive.

So drop the options.config_autosquash check from the conditions for
clearing allow_preemptive_ff, as the case where it is combined with
--interactive is already covered by the REBASE_INTERACTIVE_EXPLICIT
flag check above it.

Also drop the "apply options are incompatible with rebase.autoSquash"
error, because it is unreachable if it is restricted to --interactive,
as apply options already cause an error when used with --interactive.
Drop the tests for the error from t3422-rebase-incompatible-options.sh,
which has separate tests for the conflicts of --interactive with apply
options.

When neither --autosquash nor --no-autosquash are given, only set
options.autosquash to true if rebase.autosquash is combined with
--interactive.

Don't initialize options.config_autosquash to -1, as there is no need to
distinguish between rebase.autoSquash being unset or explicitly set to
false.

Finally, amend the rebase.autoSquash documentation to say it only
affects interactive mode.

Simon Ser 219d54ae8c format-patch: fix ignored encode_email_headers for cover letter
When writing the cover letter, the encode_email_headers option was
ignored. That is, UTF-8 subject lines and email addresses were
written out as-is, without any Q-encoding, even if
--encode-email-headers was passed on the command line.

This is due to encode_email_headers not being copied over from
struct rev_info to struct pretty_print_context. Fix that and add
