cef4fc7ebe split-index: add {add,remove}_split_index() functions
Also use the functions in cmd_update_index() in
builtin/update-index.c.

These functions will be used in a following commit to tweak
our use of the split-index feature depending on the setting
of a configuration variable.

8ffc8dc6ba log-tree: factor out fmt_output_email_subject()
Use a strbuf to store the subject prefix string and move its
construction into its own function.  This gets rid of two arbitrary
length limits and allows the string to be added by callers directly.

9e140909f6 stash: allow pathspecs in the no verb form
Now that stash_push is used in the no verb form of stash, allow
specifying the command line for this form as well.  Always use -- to
disambiguate pathspecs from other non-option arguments.

Also make git stash -p an alias for git stash push -p.  This allows
users to use git stash -p <pathspec>.

1ada5020b3 stash: use stash_push for no verb form
Now that we have stash_push, which accepts pathspec arguments, use
it instead of stash_save in git stash without any additional verbs.

Previously we allowed git stash -- -message, which is no longer allowed
after this patch.  Messages starting with a hyphen was allowed since
3c2eb80f, ("stash: simplify defaulting to "save" and reject unknown
options").  However it was never the intent to allow that, but rather it
was allowed accidentally.

df6bba0937 stash: teach 'push' (and 'create_stash') to honor pathspec
While working on a repository, it's often helpful to stash the changes
of a single or multiple files, and leave others alone.  Unfortunately
git currently offers no such option.  git stash -p can be used to work
around this, but it's often impractical when there are a lot of changes
over multiple files.

Allow 'git stash push' to take pathspec to specify which paths to stash.

d1b3b81aab submodule init: warn about falling back to a local path
When a submodule is initialized, the config variable 'submodule.<name>.url'
is set depending on the value of the same variable in the .gitmodules
file. When the URL indicates to be relative, then the url is computed
relative to its default remote. The default remote cannot be determined
accurately in all cases, such that it falls back to 'origin'.

The 'origin' remote may not exist, though. In that case we give up looking
for a suitable remote and we'll just assume it to be a local relative path.

This can be confusing to users as there is a lot of guessing involved,
which is not obvious to the user.

So in the corner case of assuming a local autoritative truth, warn the
user to lessen the confusion.

This behavior was introduced in 4d6893200 (submodule add: allow relative
repository path even when no url is set, 2011-06-06), which shared the
code with submodule-init and then ported to C in 3604242f08 (submodule:
port init from shell to C, 2016-04-15).

In case of submodule-add, this behavior makes sense in some use cases[1],
however for submodule-init there does not seem to be an immediate obvious
use case to fall back to a local submodule. However there might be, so
warn instead of die here.

While adding the warning, also clarify the behavior of relative URLs in
the documentation.

[1] e.g. http://stackoverflow.com/questions/8721984/git-ignore-files-for-public-repository-but-not-for-private
"store a secret locally in a submodule, with no intention to publish it"

("wrapper.c: delete dead function git_mkstemps()", 22-04-2016). In order

8e27391a5f http: attempt updating base URL only if no error
http.c supports HTTP redirects of the form

  http://foo/info/refs?service=git-upload-pack
  -> http://anything
  -> http://bar/info/refs?service=git-upload-pack

(that is to say, as long as the Git part of the path and the query
string is preserved in the final redirect destination, the intermediate
steps can have any URL). However, if one of the intermediate steps
results in an HTTP exception, a confusing "unable to update url base
from redirection" message is printed instead of a Curl error message
with the HTTP exception code.

This was introduced by 2 commits. Commit c93c92f ("http: update base
URLs when we see redirects", 2013-09-28) introduced a best-effort
optimization that required checking if only the "base" part of the URL
differed between the initial request and the final redirect destination,
but it performed the check before any HTTP status checking was done. If
something went wrong, the normal code path was still followed, so this
did not cause any confusing error messages until commit 6628eb4 ("http:
always update the base URL for redirects", 2016-12-06), which taught
http to die if the non-"base" part of the URL differed.

Therefore, teach http to check the HTTP status before attempting to
check if only the "base" part of the URL differed. This commit teaches
http_request_reauth to return early without updating options->base_url
upon an error; the only invoker of this function that passes a non-NULL
"options" is remote-curl.c (through "http_get_strbuf"), which only uses
options->base_url for an informational message in the situations that
this commit cares about (that is, when the return value is not HTTP_OK).

The included test checks that the redirect scheme at the beginning of
this commit message works, and that returning a 502 in the middle of the
redirect scheme produces the correct result. Note that this is different
from the test in commit 6628eb4 ("http: always update the base URL for
redirects", 2016-12-06) in that this commit tests that a Git-shaped URL
(http://.../info/refs?service=git-upload-pack) works, whereas commit
6628eb4 tests that a non-Git-shaped URL
(http://.../info/refs/foo?service=git-upload-pack) does not work (even
though Git is processing that URL) and is an error that is fatal, not
silently swallowed.

b803ae4427 docs/diffcore: unquote "Complete Rewrites" in headers
The gitdiffcore documentation quotes the term "Complete Rewrites" in
headers for no real gain. This would make sense if the term could be
easily confused if not properly grouped together. But actually, the term
is quite obvious and thus does not really need any quoting, especially
regarding that it is not used anywhere else.

But more importanly, this brings up a bug when rendering man pages: when
trying to render quotes inside of a section header, we end up with
quotes which have been misaligned to the end of line. E.g.

    diffcore-break: For Splitting Up Complete Rewrites
    --------------------------------------------------

renders as

    DIFFCORE-BREAK: FOR SPLITTING UP  COMPLETE REWRITES""

, which is obviously wrong. While this is fixable for the man pages by
using double-quotes (e.g. ""COMPLETE REWRITES""), this again breaks it
for our generated HTML pages.

So fix the issue by simply dropping quotes inside of section headers,
which is currently only done for the term "Complete Rewrites".

"git describe" and "git name-rev" have been taught to take more
than one refname patterns to restrict the set of refs to base their
naming output on, and also learned to take negative patterns to
name refs not to be used for naming via their "--exclude" option.

  describe: teach describe negative pattern matches
  describe: teach --match to accept multiple patterns
  name-rev: add support to exclude refs by pattern match

a78d9258dc cvs tests: skip tests that call "cvs commit" when running as root
Change the tests that fail to when we run the test suite as root, due
to calling "cvs commit".

The GNU cvs package has an optional compile-time CVS_BADROOT
flag. When compiled with this flag "cvs commit" will refuse to commit
anything as root. On my Debian box this isn't compiled in[1] in, but
on CentOS it is.

I've run all the t/t*cvs*.sh tests, and these are the only two that
fail. For some reason e.g. t9402-git-cvsserver-refs.sh still works as
root despite doing "cvs commit", I haven't dug into why.

This commit is technically being overzealous, we could do better by
making a mock cvs commit as root and run the tests if that works, but
I don't see any compelling reason to bend over backwards to run these
tests in all cases, just skipping them as root seems good enough.

1. Per: strings /usr/bin/cvs|grep 'is not allowed to commit'
   Using cvs 1.11.23 on CentOS, 1.12.13-MirDebian-18 on Debian.

f0252ca23c t6300: avoid creating refs/heads/HEAD
In one test, we use "git checkout --orphan HEAD" to create
an unborn branch. Confusingly, the resulting branch is named
"refs/heads/HEAD". The original probably meant something
like:

  git checkout --orphan orphaned-branch HEAD

Let's just use "orphaned-branch" here to make this less
confusing. Putting HEAD in the second argument is already
implied.

b072504ce1 commit: don't check for space twice when looking for header
Both standard_header_field() and excluded_header_field() check if
there's a space after the buffer that's handed to them.  We already
check in the caller if that space is present.  Don't bother calling
the functions if it's missing, as they are guaranteed to return 0 in
that case, and remove the now redundant checks from them.

50a01cc48c commit: be more precise when searching for headers
Search for a space character only within the current line in
read_commit_extra_header_lines() instead of searching in the whole
buffer (and possibly beyond, if it's not NUL-terminated) and then
discarding any results after the end of the current line.

33ad9ddd0b strbuf: add strbuf_add_real_path()
Add a function for appending the canonized absolute pathname of a given
path to a strbuf.  It keeps the existing contents intact, as expected of
a function of the strbuf_add() family, while avoiding copying the result
if the given strbuf is empty.  It's more consistent with the rest of the
strbuf API than strbuf_realpath(), which it's wrapping.

Also add a semantic patch demonstrating its intended usage and apply it
to the current tree.  Using strbuf_add_real_path() instead of calling
strbuf_addstr() and real_path() avoids an extra copy to a static buffer.

886ddf4777 sha1_file: release fallback base's memory in unpack_entry()
If a pack entry that's used as a delta base is corrupt, unpack_entry()
marks it as unusable and then searches the object again in the hope that
it can be found in another pack or in a loose file.  The memory for this
external base object is never released.  Free it after use.

40a18fc77c http: add an "auto" mode for http.emptyauth
This variable needs to be specified to make some types of
non-basic authentication work, but ideally this would just
work out of the box for everyone.

However, simply setting it to "1" by default introduces an
extra round-trip for cases where it _isn't_ useful. We end
up sending a bogus empty credential that the server rejects.

Instead, let's introduce an automatic mode, that works like
this:

  1. We won't try to send the bogus credential on the first
     request. We'll wait to get an HTTP 401, as usual.

  2. After seeing an HTTP 401, the empty-auth hack will kick
     in only when we know there is an auth method available
     that might make use of it (i.e., something besides
     "Basic" or "Digest").

That should make it work out of the box, without incurring
any extra round-trips for people hitting Basic-only servers.

This _does_ incur an extra round-trip if you really want to
use "Basic" but your server advertises other methods (the
emptyauth hack will kick in but fail, and then Git will
actually ask for a password).

The auto mode may incur an extra round-trip over setting
http.emptyauth=true, because part of the emptyauth hack is
to feed this blank password to curl even before we've made a
single request.

9d3343961b send-email: only allow one address per body tag
Adding comments after a tag in the body is a common practise (e.g. in
the Linux kernel) and git-send-email has been supporting this for years
by removing any trailing cruft after the address.

After some recent changes, any trailing comment is now instead appended
to the recipient name (with some random white space inserted) resulting
in undesirable noise in the headers, for example:

CC: "# 3 . 3 . x : 1b9508f : sched : Rate-limit newidle" <stable@vger.kernel.org>

Revert to the earlier behaviour of discarding anything after the (first)
address in a tag while parsing the body.

Note that multiple addresses after are still allowed after a command
line switch (and in a CC header field).

Also note that --suppress-cc=self was never honoured when using multiple
addresses in a tag.
