Our documentation uses "include::" directives to include parts that are
either reused across multiple documents or parts that we generate at
build time. Unfortunately, top-level includes are only ever resolved
relative to the base directory, which is typically the directory of the
including document. Most importantly, it is not possible to have either
asciidoc or asciidoctor search multiple directories.
It follows that both kinds of includes must live in the same directory.
This is of course a bummer for out-of-tree builds, because here the
dynamically-built includes live in the build directory whereas the
static includes live in the source directory.
Introduce a `build_dir` attribute and prepend it to all of our includes
for dynamically-built files. This attribute gets set to the build
directory and thus converts the include path to an absolute path, which
asciidoc and asciidoctor know how to resolve.
Note that this change also requires us to update "build-docdep.perl",
which tries to figure out included files such our Makefile can set up
proper build-time dependencies. This script simply scans through the
source files for any lines that match "^include::" and treats the
remainder of the line as included file path. But given that those may
now contain the "{build_dir}" variable we have to teach the script to
replace that attribute with the actual build directory.

Currently if we want to have a remote/HEAD locally that is different
from the one on the remote, but we still want to get a warning if remote
changes HEAD, our only option is to have an indiscriminate warning with
"follow_remote_head" set to "warn". Add a new option
"warn-if-not-$branch", where $branch is a branch name we do not wish to
get a warning about. If the remote HEAD is $branch do not warn,
otherwise, behave as "warn".
E.g. let's assume, that our remote origin has HEAD
set to "master", but locally we have "git remote set-head origin seen".
Setting 'remote.origin.followRemoteHEAD = "warn"' will always print
a warning, even though the remote has not changed HEAD from "master".
Setting 'remote.origin.followRemoteHEAD = "warn-if-not-master" will
squelch the warning message, unless the remote changes HEAD from
"master". Note, that should the remote change HEAD to "seen" (which we
have locally), there will still be no warning.
Improve the advice message in report_set_head to also include silencing
the warning message with "warn-if-not-$branch".

In the current implementation, if refs/remotes/$remote/HEAD does not
exist, running fetch will create it, but if it does exist it will not do
anything, which is a somewhat safe and minimal approach. Unfortunately,
for users who wish to NOT have refs/remotes/$remote/HEAD set for any
reason (e.g. so that `git rev-parse origin` doesn't accidentally point
them somewhere they do not want to), there is no way to remove this
behaviour. On the other side of the spectrum, users may want fetch to
automatically update HEAD or at least give them a warning if something
changed on the remote.
Introduce a new setting, remote.$remote.followRemoteHEAD with four
options:
- "never": do not ever do anything, not even create
- "create": the current behaviour, now the default behaviour
- "warn": print a message if remote and local HEAD is different

While Git has documented that the credential protocol is line-based,
with newlines as terminators, the exact shape of a newline has not been
documented.
From Git's perspective, which is firmly rooted in the Linux ecosystem,
it is clear that "a newline" means a Line Feed character.
However, even Git's credential protocol respects Windows line endings
(a Carriage Return character followed by a Line Feed character, "CR/LF")
by virtue of using `strbuf_getline()`.
There is a third category of line endings that has been used originally
by MacOS, and that is respected by the default line readers of .NET and
node.js: bare Carriage Returns.
Git cannot handle those, and what is worse: Git's remedy against
CVE-2020-5260 does not catch when credential helpers are used that
interpret bare Carriage Returns as newlines.
Git Credential Manager addressed this as CVE-2024-50338, but other
credential helpers may still be vulnerable. So let's not only disallow
Line Feed characters as part of the values in the credential protocol,
but also disallow Carriage Return characters.
In the unlikely event that a credential helper relies on Carriage
Returns in the protocol, introduce an escape hatch via the
`credential.protectProtocol` config setting.
This addresses CVE-2024-52006.

When asking the user interactively for credentials, we want to avoid
misleading them e.g. via control sequences that pretend that the URL
targets a trusted host when it does not.
While Git learned, over the course of the preceding commits, to disallow
URLs containing URL-encoded control characters by default, credential
helpers are still allowed to specify values very freely (apart from Line
Feed and NUL characters, anything is allowed), and this would allow,
say, a username containing control characters to be specified that would
then be displayed in the interactive terminal prompt asking the user for
the password, potentially sending those control characters directly to
the terminal. This is undesirable because control characters can be used
to mislead users to divulge secret information to untrusted sites.
To prevent such an attack vector, let's add a `git_prompt()` that forces
the displayed text to be sanitized, i.e. displaying question marks
instead of control characters.
Note: While this commit's diff changes a lot of `user@host` strings to
`user%40host`, which may look suspicious on the surface, there is a good
reason for that: this string specifies a user name, not a
<username>@<hostname> combination! In the context of t5541, the actual
combination looks like this: `user%40@127.0.0.1:5541`. Therefore, these
string replacements document a net improvement introduced by this
commit, as `user@host@127.0.0.1` could have left readers wondering where
the user name ends and where the host name begins.

Currently, server options for Git protocol v2 can only be specified via
the command line option "--server-option" or "-o", which is inconvenient
when users want to specify a list of default options to send. Therefore,
we are introducing a new configuration to hold a list of default server
options, akin to the `push.pushOption` configuration for push options.
Initially, I named the new configuration `fetch.serverOption` to align
with `push.pushOption`. However, after discussing with Patrick, it was
renamed to `remote.<name>.serverOption` as suggested, because:
1. Server options are designed to be server-specific, making it more
logical to use a per-remote configuration.
2. Using "fetch." prefixed configurations in git-clone or git-ls-remote
seems out of place and inconsistent in design.
The parsing logic for `remote.<name>.serverOption` also relies on
`transport.c:parse_transport_option`, similar to `push.pushOption`, and
they follow the same priority design:
1. Server options set in lower-priority configuration files (e.g.,
/etc/gitconfig or $HOME/.gitconfig) can be overridden or unset in
more specific repository configurations using an empty string.
2. Command-line specified server options take precedence over those from
the configuration.
Server options from configuration are stored to the corresponding
`remote.h:remote` as a new field `server_options`. The field will be
utilized in the subsequent commit to help initialize the
`server_options` of `transport.h:transport`.
And documentation have been updated accordingly.

When multiple concurrent processes try to update references in a
repository they may try to lock the same lockfiles. This can happen even
when the updates are non-conflicting and can both be applied, so it
doesn't always make sense to abort the transaction immediately. Both the
"loose" and "packed" backends thus have a grace period that they wait
for the lock to be released that can be controlled via the config values
"core.filesRefLockTimeout" and "core.packedRefsTimeout", respectively.
The reftable backend doesn't have such a setting yet and instead fails
immediately when it sees such a lock. But the exact same concepts apply
here as they do apply to the other backends.
Introduce a new "reftable.lockTimeout" config that controls how long we
may wait for a "tables.list" lock to be released. The default value of
this config is 100ms, which is the same default as we have it for the
"loose" backend.
Note that even though we also lock individual tables, this config really
only applies to the "tables.list" file. This is because individual
tables are only ever locked when we already hold the "tables.list" lock
during compaction. When we observe such a lock we in fact do not want to
compact the table at all because it is already in the process of being
compacted by a concurrent process. So applying the same timeout here
would not make any sense and only delay progress.

When scripts or background maintenance wish to perform HTTP(S) requests,
there is a risk that our stored credentials might be invalid. At the
moment, this causes the credential helper to ping the user and block the
process. Even if the credential helper does not ping the user, Git falls
back to the 'askpass' method, which includes a direct ping to the user
via the terminal.
Even setting the 'core.askPass' config as something like 'echo' will
causes Git to fallback to a terminal prompt. It uses
git_terminal_prompt(), which finds the terminal from the environment and
ignores whether stdin has been redirected. This can also block the
process awaiting input.
Create a new config option to prevent user interaction, favoring a
failure to a blocked process.
The chosen name, 'credential.interactive', is taken from the config
option used by Git Credential Manager to already avoid user
interactivity, so there is already one credential helper that integrates
with this option. However, older versions of Git Credential Manager also
accepted other string values, including 'auto', 'never', and 'always'.
The modern use is to use a boolean value, but we should still be
careful that some users could have these non-booleans. Further, we
should respect 'never' the same as 'false'. This is respected by the
implementation and test, but not mentioned in the documentation.
The implementation for the Git interactions takes place within
credential_getpass(). The method prototype is modified to return an
'int' instead of 'void'. This allows us to detect that no attempt was
made to fill the given credential, changing the single caller slightly.
Also, a new trace2 region is added around the interactive portion of the
credential request. This provides a way to measure the amount of time
spent in that region for commands that _are_ interactive. It also makes
a conventient way to test that the config option works with
'test_region'.

The object format for repositories can either be configured explicitly
by passing the `--object-format=` option to git-init(1) or git-clone(1),
or globally by setting the `GIT_DEFAULT_HASH` environment variable.
While the former makes sense, setting random environment variables is
not really a good user experience in case someone decides to only use
SHA256 repositories.
It is only natural to expect for a user that things like this can also
be configured via their config. As such, introduce a new config
"init.defaultObjectFormat", similar to "init.defaultBranch", that allows
the user to configure the default object format when creating new repos.
The precedence order now is the following, where the first one wins:
1. The `--object-format=` switch.
2. The `GIT_DEFAULT_HASH` environment variable.
3. The `init.defaultObjectFormat` config variable.
This matches the typical precedence order we use in Git. We typically
let the environment override the config such that the latter can easily
be overridden on an ephemeral basis, for example by scripts.

In the past, we used to execute `git gc --auto` as part of our automatic
housekeeping routines. As git-gc(1) may require quite some time to
perform the housekeeping, it knows to detach itself and run in the
background so that the user can continue their work.
Eventually, we refactored our automatic housekeeping to instead use the
more flexible git-maintenance(1) command. The upside of this new infra
is that the user can configure which maintenance tasks are performed, at
least to a certain degree. So while it continues to run git-gc(1) by
default, it can also be adapted to e.g. use git-multi-pack-index(1) for
maintenance of the object database.
The auto-detach of the new infra is somewhat broken though once the user
configures non-standard tasks. The problem is essentially that we detach
at the wrong level in the process hierarchy: git-maintenance(1) never
detaches itself, but instead it continues to be git-gc(1) which does.
When configured to only run the git-gc(1) maintenance task, then the
result is basically the same as before. But when configured to run other
tasks, then git-maintenance(1) will wait for these to run to completion.
Even worse, it may be that git-gc(1) runs concurrently with other
housekeeping tasks, stomping on each others feet.
Fix this bug by asking git-gc(1) to not detach when it is being invoked
via git-maintenance(1). Instead, git-maintenance(1) now respects a new
config "maintenance.autoDetach", the equivalent of "gc.autoDetach", and
detaches itself into the background when running as part of our auto
maintenance. This should continue to behave the same for all users which
use the git-gc(1) task, only. For others though, it means that we now
properly perform all tasks in the background. The default behaviour of
git-maintenance(1) when executed by the user does not change, it will
remain in the foreground unless they pass the `--detach` option.
