Hotfix.
* sb/object-store-replace:
get_main_ref_store: BUG() when outside a repository
object.c: clear replace map before freeing it
replace-object.c: remove the_repository from prepare_replace_object
object.c: free replace map in raw_object_store_clear
If we don't have a repository, then we can't initialize the
ref store. Prior to 64a741619d (refs: store the main ref
store inside the repository struct, 2018-04-11), we'd try to
access get_git_dir(), and outside a repository that would
trigger a BUG(). After that commit, though, we directly use
the_repository->git_dir; if it's NULL we'll just segfault.
Let's catch this case and restore the BUG() behavior.
Obviously we don't ever want to hit this code, but a BUG()
is a lot more helpful than a segfault if we do.

The current document mentions OBJ_* constants without their actual
values. A git developer would know these are from cache.h but that's
not very friendly to a person who wants to read this file to implement
a pack file parser.
Similarly, the deltified representation is not documented at all (the
"document" is basically patch-delta.c). Translate that C code to
English with a bit more about what ofs-delta and ref-delta mean.

b2dc968e60 (t5516: refactor oddball tests, 2008-11-07) accidentaly
broke the &&-chain in the test 'push does not update local refs on
failure', but since it was in a subshell, chain-lint couldn't notice
it.

In a while-at-it cleanup replacing a 'cd dir && <...> && cd ..' with a
subshell, commit 28391a80a9 (receive-pack: allow deletion of corrupt
refs, 2007-11-29) also moved the assignment of the $old_commit
variable to that subshell. This variable, however, is used outside of
that subshell as a parameter of check_push_result(), to check that a
ref still points to the commit where it is supposed to. With the
variable remaining unset outside the subshell check_push_result()
doesn't perform that check at all.
Use 'git -C <dir> cmd...', so we don't need to change directory, and
thus don't need the subshell either when setting $old_commit.
Furthermore, change check_push_result() to require at least three
parameters (the repo, the oid, and at least one ref), so it will catch
similar issues earlier should they ever arise.

The two JGit tests 'we can read jgit bitmaps' and 'jgit can read our
bitmaps' in 't5310-pack-bitmaps.sh' fail when run with
GIT_TEST_SPLIT_INDEX=YesPlease. Both tests create a clone of the test
repository to check bitmap interoperability with JGit. With split
indexes enabled the index in the clone repositories contains the
'link' extension, which JGit doesn't support and, consequently, an
exception aborts it:
<...>
org.eclipse.jgit.api.errors.JGitInternalException: DIRC extension 'link' not supported by this version.
at org.eclipse.jgit.dircache.DirCache.readFrom(DirCache.java:562)
<...>
Since testing bitmaps doesn't need a worktree in the first place,
let's just create bare clones for the two JGit tests, so the cloned
won't have an index, and these two tests can be executed even with
split index enabled.

In commit dc8441fdb ("config: don't implicitly use gitdir or commondir",
2017-06-14) the function git_config_with_options was renamed to
config_with_options to better reflect the fact that it does not access
the git global config or the repo config by default.
However Documentation/technical/api-config.txt still refers to the
previous name, fix that.
While at it also update the documentation about the extra parameters,

This was missed in 5982da9d2c (replace-object: allow
prepare_replace_object to handle arbitrary repositories, 2018-04-11)
Technically the code works correctly as the replace_map is the same
size in different repositories, however it is hard to read. So convert
the code to the familiar pattern of dereferencing the pointer that we
assign in the sizeof itself.

"git http-fetch" (deprecated) had an optional and experimental
"feature" to fetch only commits and/or trees, which nobody used.
This has been removed.
* ma/http-walker-no-partial:
walker: drop fields of `struct walker` which are always 1
http-fetch: make `-a` standard behaviour
* js/runtime-prefix:
Avoid multiple PREFIX definitions
git_setup_gettext: plug memory leak
gettext: avoid initialization if the locale dir is not present
Error messages from "git push" can be painted for more visibility.
* js/colored-push-errors:
config: document the settings to colorize push errors/hints
push: test to verify that push errors are colored
push: colorize errors
color: introduce support for colorizing stderr
"git gc --prune=nonsense" spent long time repacking and then
silently failed when underlying "git prune --expire=nonsense"
failed to parse its command line. This has been corrected.
* jc/parseopt-expiry-errors:
parseopt: handle malformed --expire arguments more nicely
gc: do not upcase error message shown with die()
"git fast-export" had a regression in v2.15.0 era where it skipped
some merge commits in certain cases, which has been corrected.
* ma/fast-export-skip-merge-fix:
fast-export: fix regression skipping some merge-commits
The command line completion (in contrib/) has been taught that "git
stash save" has been deprecated ("git stash push" is the preferred
spelling in the new world) and does not offer it as a possible
completion candidate when "git stash push" can be.
* tg/demote-stash-save-in-completion:
completion: make stash -p and alias for stash push -p
completion: stop showing 'save' for stash by default
When fed input that already has In-Reply-To: and/or References:
headers and told to add the same information, "git send-email"
added these headers separately, instead of appending to an existing
one, which is a violation of the RFC. This has been corrected.
* sa/send-email-dedup-some-headers:
send-email: avoid duplicate In-Reply-To/References
"git submodule status" did not check the symbolic revision name it
computed for the submodule HEAD is not the NULL, and threw it at
printf routines, which has been corrected.
* nd/submodule-status-fix:
submodule--helper: don't print null in 'submodule status'
During a "rebase -i" session, the code could give older timestamp
to commits created by later "pick" than an earlier "reword", which
has been corrected.
* js/ident-date-fix:
sequencer: reset the committer date before commits
What is queued here is only the obviously correct and
uncontroversial code clean-up part, which is an earlier 7 patches,
of a larger series.
The remainder that is not queued introduces a few configuration
variables to deal with e-signature backends with different
signature format.
* bt/gpg-interface:
gpg-interface: find the last gpg signature line
gpg-interface: extract gpg line matching helper
gpg-interface: fix const-correctness of "eol" pointer
gpg-interface: use size_t for signature buffer size
gpg-interface: modernize function declarations
gpg-interface: handle bool user.signingkey
t7004: fix mistaken tag name
"git ls-remote" learned an option to allow sorting its output based
on the refnames being shown.
* hn/sort-ls-remote:
ls-remote: create '--sort' option
"git config --get" learned the "--default" option, to help the
calling script. Building on top of the tb/config-type topic, the
"git config" learns "--type=color" type. Taken together, you can
do things like "git config --get foo.color --default blue" and get
the ANSI color sequence for the color given to foo.color variable,
or "blue" if the variable does not exist.
* tb/config-default:
builtin/config: introduce `color` type specifier
config.c: introduce 'git_config_color' to parse ANSI colors
builtin/config: introduce `--default`
The "git config" command uses separate options e.g. "--int",
"--bool", etc. to specify what type the caller wants the value to
be interpreted as. A new "--type=<typename>" option has been
introduced, which would make it cleaner to define new types.
* tb/config-type:
builtin/config.c: support `--type=<type>` as preferred alias for `--<type>`
builtin/config.c: treat type specifiers singularly
The completion script (in contrib/) learned to clear cached list of
command line options upon dot-sourcing it again in a more efficient
way.
* sg/completion-clear-cached:
completion: reduce overhead of clearing cached --options
"git worktree remove" learned that "-f" is a shorthand for
"--force" option, just like for "git worktree add".
* sb/worktree-remove-opt-force:
worktree: accept -f as short for --force for removal
The new "checkout-encoding" attribute can ask Git to convert the
contents to the specified encoding when checking out to the working
tree (and the other way around when checking in).
* ls/checkout-encoding:
convert: add round trip check based on 'core.checkRoundtripEncoding'
convert: add tracing for 'working-tree-encoding' attribute
convert: check for detectable errors in UTF encodings
convert: add 'working-tree-encoding' attribute
utf8: add function to detect a missing UTF-16/32 BOM
utf8: add function to detect prohibited UTF-16/32 BOM
utf8: teach same_encoding() alternative UTF encoding names
strbuf: add a case insensitive starts_with()

strbuf: remove unnecessary NUL assignment in xstrdup_tolower()
The scripts in contrib/emacs/ have outlived their usefulness and
have been replaced with a stub that errors out and tells the user
there are replacements.
* ab/nuke-emacs-contrib:
git{,-blame}.el: remove old bitrotting Emacs code
The build procedure "make DEVELOPER=YesPlease" learned to enable a
bit more warning options depending on the compiler used to help
developers more. There also is "make DEVOPTS=tokens" knob
available now, for those who want to help fixing warnings we
usually ignore, for example.
* nd/warn-more-for-devs:
Makefile: add a DEVOPTS to get all of -Wextra
Makefile: add a DEVOPTS to suppress -Werror under DEVELOPER
Makefile: detect compiler and enable more warnings in DEVELOPER=1
connect.c: mark die_initial_contact() NORETURN

"git config --unset a.b", when "a.b" is the last variable in an
otherwise empty section "a", left an empty section "a" behind, and
worse yet, a subsequent "git config a.c value" did not reuse that
empty shell and instead created a new one. These have been
(partially) corrected.
* js/empty-config-section-fix:
git_config_set: reuse empty sections
git config --unset: remove empty sections (in the common case)
git_config_set: make use of the config parser's event stream
git_config_set: do not use a state machine
config_set_store: rename some fields for consistency
config: avoid using the global variable `store`
config: introduce an optional event stream while parsing
t1300: `--unset-all` can leave an empty section behind (bug)
t1300: add a few more hairy examples of sections becoming empty
t1300: remove unreasonable expectation from TODO
t1300: avoid relying on a bug
config --replace-all: avoid extra line breaks
t1300: demonstrate that --replace-all can "invent" newlines
t1300: rename it to reflect that `repo-config` was deprecated
git_config_set: fix off-by-two
Code restructuring, in preparation for further work.
* ot/libify-get-ref-atom-value:
ref-filter: libify get_ref_atom_value()
ref-filter: add return value to parsers
ref-filter: change parsing function error handling
ref-filter: add return value && strbuf to handlers
ref-filter: start adding strbufs with errors
ref-filter: add shortcut to work with strbufs
Moving a submodule that itself has submodule in it with "git mv"
forgot to make necessary adjustment to the nested sub-submodules;
now the codepath learned to recurse into the submodules.
* sb/submodule-move-nested:

submodule-config: remove submodule_from_cache
submodule-config: add repository argument to submodule_from_{name, path}
submodule-config: allow submodule_free to handle arbitrary repositories
grep: remove "repo" arg from non-supporting funcs
submodule.h: drop declaration of connect_work_tree_and_git_dir
A build-time option has been added to allow Git to be told to refer
to its associated files relative to the main binary, in the same
way that has been possible on Windows for quite some time, for
Linux, BSDs and Darwin.
* dj/runtime-prefix:
Makefile: quote $INSTLIBDIR when passing it to sed
Makefile: remove unused @@PERLLIBDIR@@ substitution variable
mingw/msvc: use the new-style RUNTIME_PREFIX helper
exec_cmd: provide a new-style RUNTIME_PREFIX helper for Windows
exec_cmd: RUNTIME_PREFIX on some POSIX systems
Makefile: add Perl runtime prefix support
Makefile: generate Perl header from template file
