Junio C Hamano 6376463c37 Merge branch 'ks/combine-diff'
Teach combine-diff to honour the path-output-order imposed by
diffcore-order, and optimize how matching paths are found in
the N-way diffs made with parents.

* ks/combine-diff:
  tests: add checking that combine-diff emits only correct paths
  combine-diff: simplify intersect_paths() further
  combine-diff: combine_diff_path.len is not needed anymore
  combine-diff: optimize combine_diff_path sets intersection
  diff test: add tests for combine-diff with orderfile
  diffcore-order: export generic ordering interface

Jeff King ba928c13d7 push: detect local refspec errors early
When pushing, we do not even look at our push refspecs until
after we have made contact with the remote receive-pack and
gotten its list of refs. This means that we may go to some
work, including asking the user to log in, before realizing
we have simple errors like "git push origin matser".

We cannot catch all refspec problems, since fully evaluating
the refspecs requires knowing what the remote side has. But
we can do a quick sanity check of the local side and catch a
few simple error cases.

Jeff King 471fd3fe41 match_explicit_lhs: allow a "verify only" mode
The match_explicit_lhs function has all of the logic
necessary to verify the refspecs without actually doing any
work. This patch lets callers pass a NULL "match" pointer to
indicate they want a "verify only" operation.

For the most part, we just need to avoid writing to the NULL
pointer. However, we also have to refactor the
try_explicit_object_name sub-function; it indicates success by
allocating and returning a new ref. Instead, we give it an
"out" parameter for the match and return a numeric status.

Jacopo Notarstefano 9ef5e2a722 branch.c: delete size check of newly tracked branch names
Since commit 6f084a56 the length of a newly tracked branch name was limited
to 1019 = 1024 - 7 - 7 - 1 characters, a bound derived by having to store
this name in a char[1024] called key with two strings of length at most 7
and a '\0' character.

This was no longer necessary as of commit a9f2c136, which uses a strbuf
(documented in Documentation/technical/api-strbuf.txt) to store this value.

Remove this unneeded check to allow branch names longer than 1019
characters.

Jeff King ee34a2bead repack: add repack.packKeptObjects config var
The git-repack command always passes `--honor-pack-keep`
to pack-objects. This has traditionally been a good thing,
as we do not want to duplicate those objects in a new pack,
and we are not going to delete the old pack.

However, when bitmaps are in use, it is important for a full
repack to include all reachable objects, even if they may be
duplicated in a .keep pack. Otherwise, we cannot generate
the bitmaps, as the on-disk format requires the set of
objects in the pack to be fully closed.

Even if the repository does not generally have .keep files,
a simultaneous push could cause a race condition in which a
.keep file exists at the moment of a repack. The repack may
try to include those objects in one of two situations:

  1. The pushed .keep pack contains objects that were
     already in the repository (e.g., blobs due to a revert of
     an old commit).

  2. Receive-pack updates the refs, making the objects
     reachable, but before it removes the .keep file, the
     repack runs.

In either case, we may prefer to duplicate some objects in
the new, full pack, and let the next repack (after the .keep
file is cleaned up) take care of removing them.

This patch introduces both a command-line and config option
to disable the `--honor-pack-keep` option.  By default, it
is triggered when pack.writeBitmaps (or `--write-bitmap-index`
is turned on), but specifying it explicitly can override the
behavior (e.g., in cases where you prefer .keep files to
bitmaps, but only when they are present).

Note that this option just disables the pack-objects
behavior. We still leave packs with a .keep in place, as we
do not necessarily know that we have duplicated all of their
objects.

Commit 322bb6e12f (add update 'none' flag to disable update of submodule
by default) added the '--checkout' option to "git submodule update" but
forgot to explicitly document it in synopsis, usage string and man page
(It is only mentioned implicitly in the man page). In 23d25e48 (submodule:
explicit local branch creation in module_clone) the synopsis of the man
page was updated, but the "OPTIONS" section of the man page and the usage
string of the git-submodule script still do not mention the '--checkout'
option.

Fix that by documenting this option in usage string and the "OPTIONS"
section of man page too. While at it group the update-mode options into
a single set in the usage string.

Scott J. Goldman 7671b63211 add uploadarchive.allowUnreachable option
In commit ee27ca4, we started restricting remote git-archive
invocations to only accessing reachable commits. This
matches what upload-pack allows, but does restrict some
useful cases (e.g., HEAD:foo). We loosened this in 0f544ee,
which allows `foo:bar` as long as `foo` is a ref tip.
However, that still doesn't allow many useful things, like:

  1. Commits accessible from a ref, like `foo^:bar`, which
     are reachable

  2. Arbitrary sha1s, even if they are reachable.

We can do a full object-reachability check for these cases,
but it can be quite expensive if the client has sent us the
sha1 of a tree; we have to visit every sub-tree of every
commit in the worst case.

Let's instead give site admins an escape hatch, in case they
prefer the more liberal behavior.  For many sites, the full
object database is public anyway (e.g., if you allow dumb
walker access), or the site admin may simply decide the
security/convenience tradeoff is not worth it.

This patch adds a new config option to disable the
restrictions added in ee27ca4. It defaults to off, meaning
there is no change in behavior by default.
