rebase --autostash: fix issue with dirty submodules
Since we cannot stash dirty submodules, there is no use in requiring
them to be clean (or stash them when they are not).
This brings the built-in rebase in line with the previous, scripted
version, which also did not care about dirty submodules (but it was
admittedly not very easy to figure that out).

Documentation/config.txt: fix typo in core.alternateRefsCommand
In [1] Git learned about 'core.alternateRefsCommand', and with it, the
accompanying documentation. However, this documentation included a typo
involving the verb tense of "produced".
Match the tense of the surrounding bits by correcting this typo.
It is more common to use post-increment than pre-increment when the
side effect is the primary thing we want in our code and in C in
general (unlike C++).
Initializing a variable to 0, incrementing it every time we do
something, and checking if we have already done that thing to guard
the code to do that thing, is easier to understand when written

rebase (autostash): use an explicit OID to apply the stash
When `git stash apply <argument>` sees an argument that consists only of
digits, it tries to be smart and interpret it as `stash@{<number>}`.
Unfortunately, an all-digit hash (which is unlikely but still possible)
is therefore misinterpreted as `stash@{<n>}` reflog.
To prevent that from happening, let's append `^0` after the stash hash,
to make sure that it is interpreted as an OID rather than as a number.

rebase (autostash): store the full OID in <state-dir>/autostash
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.

gpg-interface.c: detect and reject multiple signatures on commits
GnuPG supports creating signatures consisting of multiple signature
packets. If such a signature is verified, it outputs all the status
messages for each signature separately. However, git currently does not
account for such scenario and gets terribly confused over getting
multiple *SIG statuses.
For example, if a malicious party alters a signed commit and appends
a new untrusted signature, git is going to ignore the original bad
signature and report untrusted commit instead. However, %GK and %GS
format strings may still expand to the data corresponding
to the original signature, potentially tricking the scripts into
trusting the malicious commit.
Given that the use of multiple signatures is quite rare, git does not
support creating them without jumping through a few hoops, and finally
supporting them properly would require extensive API improvement, it
seems reasonable to just reject them at the moment.

diff: don't attempt to strip prefix from absolute Windows paths
git diff can be invoked with absolute paths. Typically, this triggers
the --no-index case. Then the absolute paths remain in the file names
that are printed in the output.
There is one peculiarity, though: When the command is invoked from a
a sub-directory in a repository, then it is attempted to strip the
sub-directory from the beginning of relative paths. Yet, to detect a
relative path the code just checks for an initial forward slash.
This mistakes a Windows style path like "D:/base" as a relative path
and the output looks like this, for example:
If the sub-directory where 'git diff' is invoked is sufficiently deep
that the prefix becomes longer than the path to be printed, then the
subsequent code accesses the path out of bounds.
Use is_absolute_path() to detect Windows style absolute paths.
One might wonder whether the check for a directory separator that
is visible in the patch context should be changed from == '/' to
is_dir_sep() or not. It turns out not to be necessary. That code
only ever investigates paths that have undergone pathspec
normalization, after which there are only forward slashes even on
Windows.

receive: denyCurrentBranch=updateinstead should not blindly update
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.

pack-objects (mingw): initialize `packing_data` mutex in the correct spot
In 9ac3f0e5b3e4 (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.

In a partial clone that will lazily be hydrated from the
originating repository, we generally want to avoid "does this
object exist (locally)?" on objects that we deliberately omitted
when we created the clone. The cache-tree codepath (which is used
to write a tree object out of the index) however insisted that the
object exists, even for paths that are outside of the partial
checkout area. The code has been updated to avoid such a check.
* jt/cache-tree-allow-missing-object-in-partial-clone:
cache-tree: skip some blob checks in partial clone
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.
* tb/filter-alternate-refs:
transport.c: introduce core.alternateRefsPrefixes
transport.c: introduce core.alternateRefsCommand
transport.c: extract 'fill_alternate_refs_command'
transport: drop refnames from for_each_alternate_ref
Over some transports, fetching objects with an exact commit object
name can be done without first seeing the ref advertisements. The
code has been optimized to exploit this.
* jt/avoid-ls-refs:
fetch: do not list refs if fetching only hashes
transport: list refs before fetch if necessary
transport: do not list refs if possible
transport: allow skipping of ref listing
A partial clone that is configured to lazily fetch missing objects
will on-demand issue a "git fetch" request to the originating
repository to fill not-yet-obtained objects. The request has been
optimized for requesting a tree object (and not the leaf blob
objects contained in it) by telling the originating repository that
no blobs are needed.
* jt/non-blob-lazy-fetch:
fetch-pack: exclude blobs when lazy-fetching trees
fetch-pack: avoid object flags if no_dependents
The oidset API was built on top of the oidmap API which in turn is
on the hashmap API. Replace the implementation to build on top of
the khash API and gain performance.
* rs/oidset-on-khash:
oidset: uninline oidset_init()
oidset: use khash
khash: factor out kh_release_*
fetch-pack: load tip_oids eagerly iff needed
fetch-pack: factor out is_unmatched_ref()
Unlike "grep", "git grep" by default recurses to the whole tree.
The command learned "git grep --recursive" option, so that "git
grep --no-recursive" can serve as a synonym to setting the
max-depth to 0.
"git help -a" and "git help -av" give different pieces of
information, and generally the "verbose" version is more friendly
to the new users. "git help -a" by default now uses the more
verbose output (with "--no-verbose", you can go back to the
original). Also "git help -av" now lists aliases and external
commands, which it did not used to.
* nd/help-commands-verbose-by-default:
help -a: improve and make --verbose default
"git fetch $repo $object" in a partial clone did not correctly
fetch the asked-for object that is referenced by an object in
promisor packfile, which has been fixed.
* jt/fetch-tips-in-partial-clone:
fetch: in partial clone, check presence of targets
connected: document connectivity in partial clones
A new extension to the index file has been introduced, which allows
the file to be read in parallel.

used during tests are getting renamed for consistency.

"git commit --dry-run".

We create a client by cloning A from the server with depth 1, and add
many commits to it (so that future fetches span multiple requests due to
lengthy negotiation). If it then fetches B using protocol v2, the fetch
spanning multiple requests, the resulting packfile does not contain O
even though the client did report that A is shallow.
This is because upload_pack_v2() can be called multiple times while
processing the same session. During the 2nd and all subsequent
invocations, some object flags remain from the previous invocations. In
particular, CLIENT_SHALLOW remains, preventing process_shallow() from
adding client-reported shallows to the "shallows" array, and hence
pack-objects not knowing about these client-reported shallows.
Therefore, teach upload_pack_v2() to clear object flags at the start of
each invocation. This has some other results:
- THEY_HAVE gates addition of objects to have_obj in process_haves().
Previously in upload_pack_v2(), have_obj needed to be static because
once an object is added to have_obj, it is never readded and thus we
needed to retain the contents of have_obj between invocations. Now
that flags are cleared, this is no longer necessary. This patch does
not change the behavior of ok_to_give_up() (THEY_HAVE is still set on
each "have") and got_oid() (used only in non-v2)); THEY_HAVE is not
used in any other function.
- WANTED gates addition of objects to want_obj in parse_want() and
parse_want_ref(). It is also used in receive_needs(), but that is
only used in non-v2. For the same reasons as THEY_HAVE, want_obj no
longer needs to be static in upload_pack_v2().
- CLIENT_SHALLOW is changed as discussed above.
Clearing of the other 5 flags does not affect functionality in v2. (Note
that in non-v2, upload_pack() is only called once per process, so each
invocation starts with blank flags anyway.)
- OUR_REF is only used in non-v2.
- COMMON_KNOWN is only used as a scratch flag in ok_to_give_up().
- SHALLOW is passed to invocations in deepen() and
deepen_by_rev_list(), but upload-pack doesn't use it.
- NOT_SHALLOW is used by send_shallow() and send_unshallow(), but
invocations of those functions are always preceded by code that sets
NOT_SHALLOW on the appropriate objects.
- HIDDEN_REF is only used in non-v2.

The algorithm in can_all_from_reach_with_flags() performs a depth-
first-search, terminated by generation number, intending to use
a hueristic that "important" commits are found in the first-parent
history. This heuristic is valuable in scenarios like fetch
negotiation.
However, there is a problem! After the search finds a target commit,
it should pop all commits off the stack and mark them as "can reach".
This logic is incorrect, so the algorithm instead walks all reachable
commits above the generation-number cutoff.
The existing algorithm is still an improvement over the previous
algorithm, as the worst-case complexity went from quadratic to linear.
The performance measurement at the time was good, but not dramatic.
By fixing this heuristic, we reduce the number of walked commits.
We can also re-run the performance tests from commit 4fbcca4e
"commit-reach: make can_all_from_reach... linear".
Performance was measured on the Linux repository using
'test-tool reach can_all_from_reach'. The input included rows seeded by
tag values. The "small" case included X-rows as v4.[0-9]* and Y-rows as
v3.[0-9]*. This mimics a (very large) fetch that says "I have all major
v3 releases and want all major v4 releases." The "large" case included
X-rows as "v4.*" and Y-rows as "v3.*". This adds all release-candidate
tags to the set, which does not greatly increase the number of objects
that are considered, but does increase the number of 'from' commits,
demonstrating the quadratic nature of the previous code.
Small Case:
4fbcca4e~1: 0.85 s 4fbcca4e: 0.26 s (num_walked: 1,011,035)
HEAD: 0.14 s (num_walked: 8,601)
Large Case:
4fbcca4e~1: 24.0 s 4fbcca4e: 0.12 s (num_walked: 503,925)

We explicitly omitted -Wunused-function when we added
-Wextra, but there is no need: the current code compiles
cleanly with it. And it's worth having, since it can let you
know when there are cascading effects from a cleanup (e.g.,
deleting one function lets you delete its static helpers).
There are cases where we may need an unused function to
exist, but we can handle these easily:
- macro-generated code like commit-slab; there we have the
MAYBE_UNUSED annotation to silence the compiler
- conditional compilation, where we may or may not need a
static helper. These generally fall into one of two
categories:
- the call should not be conditional, but rather the
function body itself should be (and may just be a
no-op on one side of the #if). That keeps the
conditional pollution out of the main code.
- call-chains of static helpers should all be in the
same #if block, so they are all-or-nothing
And if there's some case that doesn't cover, we still
have MAYBE_UNUSED as a fallback.

The commit-graph and multi-pack-index features introduce optional

It is important to run the normal test suite without them enabled,

Our continuous integration scripts include a second test stage that
runs with optional GIT_TEST_* variables enabled. Add the following
two variables to that stage:
GIT_TEST_COMMIT_GRAPH
GIT_TEST_MULTI_PACK_INDEX
This will slow down the operation, as we build a commit-graph file
after every 'git commit' operation and build a multi-pack-index
during every 'git repack' operation. However, it is important that
future changes are compatible with these features.

merge-recursive: avoid showing conflicts with merge branch before HEAD
We want to load unmerged entries from HEAD into the index at stage 2 and
from MERGE_HEAD into stage 3. Similarly, folks expect merge conflicts
to look like
<<<<<<<< HEAD
content from our side
========
content from their side
>>>>>>>> MERGE_HEAD
not
<<<<<<<< MERGE_HEAD
content from their side
========
content from our side
>>>>>>>> HEAD
The correct order usually comes naturally and for free, but with renames
we often have data in the form {rename_branch, other_branch}, and
working relative to the rename first (e.g. for rename/add) is more
convenient elsewhere in the code. Address the slight impedance
mismatch by having some functions re-call themselves with flipped
arguments when the branch order is reversed.
Note that setup_rename_conflict_info() has one asymmetry in it, in
setting dst_entry1->processed=0 but not doing similarly for
dst_entry2->processed. When dealing with rename/rename and similar
conflicts, we do not want the processing to happen twice, so the
desire to only set one of the entries to unprocessed is intentional.
So, while this change modifies which branch's entry will be marked as
unprocessed, that dovetails nicely with putting HEAD first so that we
get the index stage entries and conflict markers in the right order.

merge-recursive: improve auto-merging messages with path collisions
Each individual file involved in a rename could have also been modified

instead be:
Auto-merging version of somefile.c from somecase.c
Auto-merging version of somefile.c from someportfolio.c
Auto-merging somefile.c
This is an admittedly long set of messages for a single path, but you
only get all three messages when dealing with the rare case of a
rename/rename(2to1) conflict where both sides of both original files
were also modified, in conflicting ways.

I noticed 74d4731da1 (submodule--helper: replace connect-gitdir-workingtree
by ensure-core-worktree, 2018-08-13) had two leftover debugging statements
when reading The coverage report [1]. Remove them.
submodule helper: convert relative URL to absolute URL if needed
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

function) and call it at the appropriate place in the update_clone helper.

branch_get sometimes returns current_branch, which can be NULL (e.g., if
you're on a detached HEAD). Try:
$ git branch HEAD
fatal: no such branch 'HEAD'
$ git branch ''
fatal: no such branch ''
However, it seems weird that we'd check those cases here (and provide
such lousy messages). And indeed, dropping that and letting us
eventually hit create_branch() gives a much better message:
$ git branch HEAD
fatal: 'HEAD' is not a valid branch name.
$ git branch ''
fatal: '' is not a valid branch name.

send-email: also pick up cc addresses from -by trailers
When rerolling a patch series, including various Reviewed-by etc. that
may have come in, it is quite convenient to have git-send-email
automatically cc those people.
So pick up any *-by lines, with a new suppression category 'misc-by',
but special-case Signed-off-by, since that already has its own
suppression category. It seems natural to make 'misc-by' implied by
'body'.

The minimum version of Windows supported by Windows port fo Git is
now set to Vista.
* js/mingw-wants-vista-or-above:
mingw: bump the minimum Windows version to Vista
mingw: set _WIN32_WINNT explicitly for Git for Windows
compat/poll: prepare for targeting Windows Vista

Doc: refer to the "commit-graph file" with dash
git-commit-graph.txt: refer to "*commit*-graph file"
git-commit-graph.txt: typeset more in monospace
git-commit-graph.txt: fix bullet lists
The code in "git status" sometimes hit an assertion failure. This
was caused by a structure that was reused without cleaning the data
used for the first run, which has been corrected.

commit: fix erroneous BUG, 'multiple renames on the same target? how?'
"gc --auto" ended up calling exit(-1) upon error, which has been
corrected to use exit(1). Also the error reporting behaviour when
daemonized has been updated to exit with zero status when stopping
due to a previously discovered error (which implies there is no
point running gc to improve the situation); we used to exit with
failure in such a case.
* jn/gc-auto:
gc: do not return error for prior errors in daemonized mode
* fe/doc-updates:
git-describe.1: clarify that "human readable" is also git-readable
git-column.1: clarify initial description, provide examples

An alias that expands to another alias has so far been forbidden,
but now it is allowed to create such an alias.
