It was reported by Gábor Szeder and analyzed by Alban Gruin that the
built-in rebase stores only abbreviated stash hashes in the `autostash`
file.
This is problematic e.g. in t5520-pull.sh, where the abbreviated hash is
so short that it sometimes consists only of digits, which are
subsequently mistaken ("DWIMmed") for numbers by `git stash apply`.
Let's align the behavior of the built-in rebase with the scripted rebase
and store the full stash hash instead. That makes it a lot less likely
that it consists only of digits.

A new repo extension is added, worktreeConfig. When it is present:
- Repository config reading by default includes $GIT_DIR/config _and_
$GIT_DIR/config.worktree. "config" file remains shared in multiple
worktree setup.
- The special treatment for core.bare and core.worktree, to stay
effective only in main worktree, is gone. These config settings are
supposed to be in config.worktree.
This extension is most useful in multiple worktree setup because you
now have an option to store per-worktree config (which is either
.git/config.worktree for main worktree, or
.git/worktrees/xx/config.worktree for linked ones).
This extension can be used in single worktree mode, even though it's
pretty much useless (but this can happen after you remove all linked
worktrees and move back to single worktree).
"git config" reads from both "config" and "config.worktree" by default
(i.e. without either --user, --file...) when this extension is
present. Default writes still go to "config", not "config.worktree". A
new option --worktree is added for that (*).
Since a new repo extension is introduced, existing git binaries should
refuse to access to the repo (both from main and linked worktrees). So
they will not misread the config file (i.e. skip the config.worktree
part). They may still accidentally write to the config file anyway if
they use with "git config --file <path>".
This design places a bet on the assumption that the majority of config
variables are shared so it is the default mode. A safer move would be
default writes go to per-worktree file, so that accidental changes are
isolated.
(*) "git config --worktree" points back to "config" file when this
extension is not present and there is only one worktree so that it
works in any both single and multiple worktree setups.

The multi-pack-index feature is tested in isolation by
t5319-multi-pack-index.sh, but there are many more interesting
scenarios in the test suite surrounding pack-file data shapes
and interactions. Since the multi-pack-index is an optional
data structure, it does not make sense to include it by default
in those tests.
Instead, add a new GIT_TEST_MULTI_PACK_INDEX environment variable
that enables core.multiPackIndex and writes a multi-pack-index
after each 'git repack' command. This adds extra test coverage
when needed.
There are a few spots in the test suite that need to react to this
change:
* t5319-multi-pack-index.sh: there is a test that checks that
'git repack' deletes the multi-pack-index. Disable the environment
variable to ensure this still happens.
* t5310-pack-bitmaps.sh: One test moves a pack-file from the object
directory to an alternate. This breaks the multi-pack-index, so
delete the multi-pack-index at this point, if it exists.
* t9300-fast-import.sh: One test verifies the number of files in
the .git/objects/pack directory is exactly 8. Exclude the
multi-pack-index from this count so it is still 8 in all cases.

The handling of receive.denyCurrentBranch=updateInstead was added to
a switch statement that handles other values of the variable, but
all the other case arms only checked a condition to reject the
attempted push, or let later logic in the same function to still
intervene, so that a push that does not fast-forward (which is
checked after the switch statement in question) is still rejected.
But the handling of updateInstead incorrectly took immediate effect,
without giving other checks a chance to intervene.
Instead of calling update_worktree() that causes the side effect
immediately, just note the fact that we will need to call the
function later, and first give other checks a chance to reject the
request. After the update-hook gets a chance to reject the push
(which happens as the last step in a series of checks), call
update_worktree() when we earlier detected the need to.

In 9ac3f0e5b3 (pack-objects: fix performance issues on packing large
deltas, 2018-07-22), a mutex was introduced that is used to guard the
call to set the delta size. This commit even added code to initialize
it, but at an incorrect spot: in `init_threaded_search()`, while the
call to `oe_set_delta_size()` (and hence to `packing_data_lock()`) can
happen in the call chain `check_object()` <- `get_object_details()` <-
`prepare_pack()` <- `cmd_pack_objects()`, which is long before the
`prepare_pack()` function calls `ll_find_deltas()` (which initializes
the threaded search).
Another tell-tale that the mutex was initialized in an incorrect spot is
that the function to initialize it lives in builtin/, while the code
that uses the mutex is defined in a libgit.a header file.
Let's use a more appropriate function: `prepare_packing_data()`, which
not only lives in libgit.a, but *has* to be called before the
`packing_data` struct is used that contains that mutex.
This fixes https://github.com/git-for-windows/git/issues/1839.

When pushing into a repository that borrows its objects from an
alternate object store, "git receive-pack" that responds to the
push request on the other side lists the tips of refs in the
alternate to reduce the amount of objects transferred. This
sometimes is detrimental when the number of refs in the alternate
is absurdly large, in which case the bandwidth saved in potentially
fewer objects transferred is wasted in excessively large ref
advertisement. The alternate refs that are advertised are now
configurable with a pair of configuration variables.

The submodule helper update_clone called by "git submodule update",
clones submodules if needed. As submodules used to have the URL indicating
if they were active, the step to resolve relative URLs was done in the
"submodule init" step. Nowadays submodules can be configured active without
calling an explicit init, e.g. via configuring submodule.active.
When trying to obtain submodules that are set active this way, we'll
fallback to the URL found in the .gitmodules, which may be relative to the
superproject, but we do not resolve it, yet:
git clone https://gerrit.googlesource.com/gerrit
cd gerrit && grep url .gitmodules
url = ../plugins/codemirror-editor
...
git config submodule.active .
git submodule update
fatal: repository '../plugins/codemirror-editor' does not exist
fatal: clone of '../plugins/codemirror-editor' into submodule path '/tmp/gerrit/plugins/codemirror-editor' failed

[...]
fatal: clone of '../plugins/codemirror-editor' into submodule path '/tmp/gerrit/plugins/codemirror-editor' failed
Failed to clone 'plugins/codemirror-editor' a second time, aborting
[...]
To resolve the issue, factor out the function that resolves the relative
URLs in "git submodule init" (in the submodule helper in the init_submodule
function) and call it at the appropriate place in the update_clone helper.

The builtin rebase and the builtin interactive rebase have been
developed independently, on purpose: Google Summer of Code rules
specifically state that students have to work on independent projects,
they cannot collaborate on the same project.
One fallout is that the rebase-in-c and rebase-i-in-c patches cause no
merge conflicts but a royal number of tests in the test suite to fail.
It is easy to explain why: rebase-in-c was developed under the
assumption that all rebase backends are implemented in Unix shell script
and can be sourced via `. git-rebase--<backend>`, which is no longer
true with rebase-i-in-c, where git-rebase--interactive is a hard-linked
builtin.
This patch fixes that.
Please note that we also skip the finish_rebase() call for interactive
rebases because the built-in interactive rebase already takes care of
that. This is needed to support the upcoming `break` command that wants
to interrupt the rebase with exit code 0 (and naturally wants to keep
the state directory intact when doing so).
While at it, remove the `case` arm for the interactive rebase that is
now skipped in favor of the short-cut to the built-in rebase.
