2b3ae04011 add-patch: add diff.context command line overrides
This patch compliments the previous commit, where builtins that use
add-patch infrastructure now respect diff.context and
diff.interHunkContext file configurations.

In particular, this patch helps users who don't want to set persistent
context configurations or just want a way to override them on a one-time
basis, by allowing the relevant builtins to accept corresponding command
line options that override the file configurations.

This mimics commands such as diff and log, which allow for both context
file configuration and command line overrides.

7e2943128e blame: remove parameter detailed in get_commit_info()
The get_commit_info() function accepts a parameter that can be used
to stop the commit parsing early.  However, none of the callers use
this feature, and testing proved that the performance gain of
stopping parsing early is negligible and unmeasurable.

fa0f4e46f5 for-each-ref: reword the documentation for '--start-after'
The documentation for '--start-after' states that the flag cannot be
used with general pattern matching. This is a bit vague, since there is
no clear understanding about what 'general' means here. Rewrite the
sentence to be more specific.

While here, fix a typo in the 'OPT_STRING'.

08b775864e config: move Git config parsing into "environment.c"
In "config.c" we host both the business logic to read and write config
files as well as the logic to parse specific Git-related variables. On
the one hand this is mixing concerns, but even more importantly it means
that we cannot easily remove the dependency on `the_repository` in our
config parsing logic.

Move the logic into "environment.c". This file is a grab bag of all
kinds of global state already, so it is quite a good fit. Furthermore,
it also hosts most of the global variables that we're parsing the config
values into, making this an even better fit.

Note that there is one hidden change: in `parse_fsync_components()` we
use an `int` to iterate through `ARRAY_SIZE(fsync_component_names)`. But
as -Wsign-compare warnings are enabled in this file this causes a
compiler warning. The issue is fixed by using a `size_t` instead.

This change allows us to drop the `USE_THE_REPOSITORY_VARIABLE`
declaration.

a538250d97 config: drop git_config_set_multivar() wrapper
In 036876a106 (config: hide functions using `the_repository` by
default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.

Follow through with that intent and remove `git_config_set_multivar()`.
All callsites are adjusted so that they use
`repo_config_set_multivar(the_repository, ...)` instead. While some
callsites might already have a repository available, this mechanical
conversion is the exact same as the current situation and thus cannot
cause any regression. Those sites should eventually be cleaned up in a
later patch series.

takes in a repository as parameter, and the intent was that we'll

Follow through with that intent and remove `git_config_get()`. All
callsites are adjusted so that they use `repo_config_get(the_repository,
...)` instead. While some callsites might already have a repository
available, this mechanical conversion is the exact same as the current
situation and thus cannot cause any regression. Those sites should
eventually be cleaned up in a later patch series.

26552cb62a reflog: close leak of reflog expire entry
find_cfg_ent() allocates a struct reflog_expire_entry_option via
FLEX_ALLOC_MEM and inserts it into a linked list in the
reflog_expire_options structure. The entries in this list are never
freed, resulting in a leak in cmd_reflog_expire and the gc reflog expire
maintenance task:

Direct leak of 39 byte(s) in 1 object(s) allocated from:

Close this leak by adding a reflog_clear_expire_config() function which
iterates the linked list and frees its elements. Call it upon exit of
cmd_reflog_expire() and reflog_expire_condition().

Add a basic test which covers this leak. While at it, cover the
functionality from commit commit 3cb22b8efe (Per-ref reflog expiry
configuration, 2008-06-15). We've had this support for years, but lacked
any tests.

e3378607c8 pull: add pull.autoStash config option
Git uses `rebase.autostash` or `merge.autostash` to determine whether a
dirty worktree is allowed during pull. However, this behavior is not
clearly documented, making it difficult for users to discover how to
enable autostash, or causing them to unknowingly enable it. Add new
config option `pull.autostash` along with its documentation and test
cases.

`pull.autostash` provides the same functionality as `rebase.autostash`
and `merge.autostash`, but overrides them when set. If `pull.autostash`
is not set, it falls back to `rebase.autostash` or `merge.autostash`,
depending on the value of `pull.rebase`.

54b18261eb revision: drop early output option
We added the --early-output feature long ago in cdcefbc971 (Add
"--early-output" log flag for interactive GUI use, 2007-11-03). The idea
was that GUIs could use it to progressively render a history view,
showing something quick-and-inaccurate at first and then enhancing it
later.

But we never documented it, and it appears never to have been used, even
by the projects which initially expressed interest. There was an RFC
patch for gitk to use it:

  http://public-inbox.org/git/18221.2285.259487.655684@cargo.ozlabs.ibm.com/

but it was never merged. Likewise QGit had a patch in:

  https://lore.kernel.org/git/e5bfff550711040225ne67c907r2023b1354c35f35@mail.gmail.com/

but it was never fully merged (to this day, QGit has a commented-out line to
add "--early-output" to the "log" invocation). Searching for other
mentions on the web or forges like github.com turns up nothing.

Meanwhile, the feature has been broken off and on over the years without
anybody noticing (and naturally, there are no tests, either). From 2011
to 2017 the option didn't even turn on via "--early-output"; this was
fixed in e35b6ac56f (revision.h: turn rev_info.early_output back into an
unsigned int, 2017-06-10).

It worked for a while then, but it does not interact well at all with
commit-graphs (which are turned on by default these days). The main
logic to count early commits is triggered by limit_list(), which we
traditionally invoked when showing output in topo-order (and
--early-output always enables --topo-order). But that changed in
f0d9cc4196 (revision.c: begin refactoring --topo-order logic,
2018-11-01). Now when we have generation numbers, we skip limit_list()
entirely, and the early-output code shows no commits, and just the final
header "Final output: 1 done". Which is syntactically OK, but
semantically wrong: that message should give the total number of commits
we're about to show.

So let's drop the feature. It is extra code that is untested and
undocumented, and makes working on the revision machinery more brittle.

Given the history above, it seems unlikely that anybody is using it (or
has used it), and we can drop it without the usual deprecation period.

A gentler option might be to "soft" drop it: keep accepting the option,
have it imply --topo-order as it does now, print "Final output: 1 done",
and then do our regular traversal. That would keep any hypothetical
caller working. But it doesn't seem worth the hassle to me.

c2b5d1490a object-file: get rid of the_repository in force_object_loose()
The function `force_object_loose()` forces an object to become a loose
object in case it only exists in its packed form. To do so it implicitly
relies on `the_repository`.

Refactor the function by passing a `struct odb_source` as parameter.
While the check whether any such loose object exists already acts on the
whole object database, writing the loose object happens in one specific
source.

0df005353a object-file: get rid of the_repository in read_loose_object()
The function `read_loose_object()` takes a path to an object file and
tries to parse it. As such, the function does not depend on any specific
object database but instead acts as an ODB-independent way to read a
specific file. As such, all it needs as input is a repository so that we
can derive repo settings and the hash algorithm.

That repository isn't passed in as a parameter though, as we implicitly
depend on the global `the_repository`. Refactor the function so that we
pass in the repository as a parameter.

d81712ce65 object-file: get rid of the_repository in loose object iterators
The iterators for loose objects still rely on `the_repository`. Refactor
them:

  - `for_each_loose_file_in_objdir()` is refactored so that the caller
    is now expected to pass an `odb_source` as parameter instead of the
    path to that source. Furthermore, it is renamed accordingly to
    `for_each_loose_file_in_source()`.

  - `for_each_loose_object()` is refactored to take in an object
    database now and calls the above function in a loop.

This allows us to get rid of the global dependency.

Adjust callers accordingly.

ab1c6e1d12 odb: introduce odb_write_object()
We do not have a backend-agnostic way to write objects into an object
database. While there is `write_object_file()`, this function is rather
specific to the loose object format.

Introduce `odb_write_object()` to plug this gap. For now, this function
is a simple wrapper around `write_object_file()` and doesn't even use
the passed-in object database yet. This will change in subsequent
commits, where `write_object_file()` is converted so that it works on
top of an `odb_source`. `odb_write_object()` will then become
responsible for deciding which source an object shall be written to.

cbb388f3e5 object-file: get rid of the_repository in finalize_object_file()
We implicitly depend on `the_repository` when moving an object file into
place in `finalize_object_file()`. Get rid of this global dependency by
passing in a repository.

Note that one might be pressed to inject an object database instead of a
repository. But the function doesn't really care about the ODB at all.
All it does is to move a file into place while checking whether there is
any collision. As such, the functionality it provides is independent of
the object database and only needs the repository as parameter so that
it can adjust permissions of the file we are about to finalize.
