273c61496f submodule-config: ban submodule paths that start with a dash
We recently banned submodule urls that look like
command-line options. This is the matching change to ban
leading-dash paths.

As with the urls, this should not break any use cases that
currently work. Even with our "--" separator passed to
git-clone, git-submodule.sh gets confused. Without the code
portion of this patch, the clone of "-sub" added in t7417
would yield results like:

    /path/to/git-submodule: 410: cd: Illegal option -s
    /path/to/git-submodule: 417: cd: Illegal option -s
    /path/to/git-submodule: 410: cd: Illegal option -s
    /path/to/git-submodule: 417: cd: Illegal option -s
    Fetched in submodule path '-sub', but it did not contain b56243f8f4eb91b2f1f8109452e659f14dd3fbe4. Direct fetching of that commit failed.

Moreover, naively adding such a submodule doesn't work:

  $ git submodule add $url -sub
  The following path is ignored by one of your .gitignore files:
  -sub

even though there is no such ignore pattern (the test script
hacks around this with a well-placed "git mv").

Unlike leading-dash urls, though, it's possible that such a
path _could_ be useful if we eventually made it work. So
this commit should be seen not as recommending a particular
policy, but rather temporarily closing off a broken and
possibly dangerous code-path. We may revisit this decision
later.

There are two minor differences to the tests in t7416 (that
covered urls):

  1. We don't have a "./-sub" escape hatch to make this
     work, since the submodule code expects to be able to
     match canonical index names to the path field (so you
     are free to add submodule config with that path, but we
     would never actually use it, since an index entry would
     never start with "./").

  2. After this patch, cloning actually succeeds. Since we
     ignore the submodule.*.path value, we fail to find a
     config stanza for our submodule at all, and simply
     treat it as inactive. We still check for the "ignoring"
     message.

f6adec4e32 submodule-config: ban submodule urls that start with dash
The previous commit taught the submodule code to invoke our
"git clone $url $path" with a "--" separator so that we
aren't confused by urls or paths that start with dashes.

However, that's just one code path. It's not clear if there
are others, and it would be an easy mistake to add one in
the future. Moreover, even with the fix in the previous
commit, it's quite hard to actually do anything useful with
such an entry. Any url starting with a dash must fall into
one of three categories:

 - it's meant as a file url, like "-path". But then any
   clone is not going to have the matching path, since it's
   by definition relative inside the newly created clone. If
   you spell it as "./-path", the submodule code sees the
   "/" and translates this to an absolute path, so it at
   least works (assuming the receiver has the same
   filesystem layout as you). But that trick does not apply
   for a bare "-path".

 - it's meant as an ssh url, like "-host:path". But this
   already doesn't work, as we explicitly disallow ssh
   hostnames that begin with a dash (to avoid option
   injection against ssh).

 - it's a remote-helper scheme, like "-scheme::data". This
   _could_ work if the receiver bends over backwards and
   creates a funny-named helper like "git-remote--scheme".
   But normally there would not be any helper that matches.

Since such a url does not work today and is not likely to do
anything useful in the future, let's simply disallow them
entirely. That protects the existing "git clone" path (in a
belt-and-suspenders way), along with any others that might
exist.

Our tests cover two cases:

  1. A file url with "./" continues to work, showing that
     there's an escape hatch for people with truly silly
     repo names.

  2. A url starting with "-" is rejected.

Note that we expect case (2) to fail, but it would have done
so even without this commit, for the reasons given above.
So instead of just expecting failure, let's also check for
the magic word "ignoring" on stderr. That lets us know that
we failed for the right reason.

98afac7a7c submodule--helper: use "--" to signal end of clone options
When we clone a submodule, we call "git clone $url $path".
But there's nothing to say that those components can't begin
with a dash themselves, confusing git-clone into thinking
they're options. Let's pass "--" to make it clear what we
expect.

There's no test here, because it's actually quite hard to
make these names work, even with "git clone" parsing them
correctly. And we're going to restrict these cases even
further in future commits. So we'll leave off testing until
then; this is just the minimal fix to prevent us from doing
something stupid with a badly formed entry.

252d079cbd read-cache.c: optimize reading index format v4
Index format v4 requires some more computation to assemble a path
based on a previous one. The current code is not very efficient
because

 - it doubles memory copy, we assemble the final path in a temporary
   first before putting it back to a cache_entry

 - strbuf_remove() in expand_name_field() is not exactly a good fit
   for stripping a part at the end, _setlen() would do the same job
   and is much cheaper.

 - the open-coded loop to find the end of the string in
   expand_name_field() can't beat an optimized strlen()

This patch avoids the temporary buffer and writes directly to the new
cache_entry, which addresses the first two points. The last point
could also be avoided if the total string length fits in the first 12
bits of ce_flags, if not we fall back to strlen().

Running "test-tool read-cache 100" on webkit.git (275k files), reading
v2 only takes 4.226 seconds, while v4 takes 5.711 seconds, 35% more
time. The patch reduces read time on v4 to 4.319 seconds.

255eb03edf mailmap: consistently normalize brian m. carlson's name
v2.18.0-rc0~70^2 (mailmap: update brian m. carlson's email address,
2018-05-08) changed the mailmap to map

  sandals@crustytoothpaste.ath.cx
   -> brian m. carlson <sandals@crustytoothpaste.net>

instead of

  sandals@crustytoothpaste.net
    -> brian m. carlson <sandals@crustytoothpaste.ath.cx>

That means the mapping

  Brian M. Carlson <sandals@crustytoothpaste.ath.cx>
    -> brian m. carlson <sandals@crustytoothpaste.net>

is redundant, so we can remove it.  More importantly, it means that
the identity "Brian M. Carlson <sandals@crustytoothpaste.net>" used in
some commits is not normalized any more.  Add a mapping for it.

Noticed while updating Debian's Git packaging, which uses "git
shortlog --no-merges" to produce a list of changes in each version,
grouped by author's (normalized) name.

"commit-reach: properly peel tags" was merged to master quickly.

There were a few more cleanups left to apply in the series, which
are included by this change:

1. Clean up a comment that is in the incorrect style.

2. Replace multiple calls to clear_commit_marks() with one call to
   clear_commit_marks_many().

29e8dc50ad t5551: compare sorted cookies files
In t5551 we check that we save cookies correctly to a file when
http.cookiefile and http.savecookies are set.  To do so we create an
expect file that expects the cookies in a certain order.

However after e2ef8d6fa ("cookies: support creation-time attribute for
cookies", 2018-08-28) in curl.git (released in curl 7.61.1) that order
changed.

We document the file format as "Netscape/Mozilla cookie file
format (see curl(1))", so any format produced by libcurl should be
fine here.  Sort the files, to be agnostic to the order of the
cookies, and make the test pass with both curl versions > 7.61.1 and
earlier curl versions.

35f9e3e5e7 fetch: in partial clone, check presence of targets
When fetching an object that is known as a promisor object to the local
repository, the connectivity check in quickfetch() in builtin/fetch.c
succeeds, causing object transfer to be bypassed. However, this should
not happen if that object is merely promised and not actually present.

Because this happens, when a user invokes "git fetch origin <sha-1>" on
the command-line, the <sha-1> object may not actually be fetched even
though the command returns an exit code of 0. This is a similar issue
(but with a different cause) to the one fixed by a0c9016abd
("upload-pack: send refs' objects despite "filter"", 2018-07-09).

Therefore, update quickfetch() to also directly check for the presence
of all objects to be fetched. Its documentation and name are also
updated to better reflect what it does.

4067a64672 commit-reach: fix memory and flag leaks
The can_all_from_reach_with_flag() method uses 'assign_flag' as a
value we can use to mark objects temporarily during our commit walk.
The intent is that these flags are removed from all objects before
returning. However, this is not the case.

The 'from' array could also contain objects that are not commits, and
we mark those objects with 'assign_flag'. Add a loop to the 'cleanup'
section that removes these markers.

Also, we forgot to free() the memory for 'list', so add that to the
'cleanup' section.

The can_all_from_reach_with_flag() algorithm was refactored in 4fbcca4e
"commit-reach: make can_all_from_reach... linear" but incorrectly
assumed that all objects provided were commits. During a fetch
negotiation, ok_to_give_up() in upload-pack.c may provide unpeeled tags
to the 'from' array. The current code creates a segfault.

Add a direct call to can_all_from_reach_with_flag() in 'test-tool reach'
and add a test in t6600-test-reach.sh that demonstrates this segfault.

Correct the issue by peeling tags when investigating the initial list
of objects in the 'from' array.

Deep in update_paths() and find_conflict(), hold_locked_index() and
read_index() are called. These functions assumes the index path at
$GIT_DIR/index which is not always true when you take an arbitrary
index state. Taking a repository will allow us to point to the right
index path later when we replace them with repo_ versions.
