Stefan Beller 6e7c14e65c submodule update --init: display correct path from submodule
In the submodule helper we did not correctly handled the display path
for initializing submodules when both the submodule is inside a
subdirectory as well as the command being invoked from a subdirectory
(as viewed from the superproject).

This was broken in 3604242f08, which was written at a time where
there was no super-prefix available, so we abused the --prefix option
for the same purpose and could get only one case right (the call from
within a subdirectory, not the submodule being in a subdirectory).

SZEDER Gábor c026557a37 versioncmp: generalize version sort suffix reordering
The 'versionsort.prereleaseSuffix' configuration variable, as its name
suggests, is supposed to only deal with tagnames with prerelease
suffixes, and allows sorting those prerelease tags in a user-defined
order before the suffixless main release tag, instead of sorting them
simply lexicographically.

However, the previous changes in this series resulted in an
interesting and useful property of version sort:

  - The empty string as a configured suffix matches all tagnames,
    including tagnames without any suffix, but

  - tagnames containing a "real" configured suffix are still ordered
    according to that real suffix, because any longer suffix takes
    precedence over the empty string.

Exploiting this property we can easily generalize suffix reordering
and specify the order of tags with given suffixes not only before but
even after a main release tag by using the empty suffix to denote the
position of the main release tag, without any algorithm changes:

  $ git -c versionsort.prereleaseSuffix=-alpha \
        -c versionsort.prereleaseSuffix=-beta \
        -c versionsort.prereleaseSuffix="" \
        -c versionsort.prereleaseSuffix=-gamma \
        -c versionsort.prereleaseSuffix=-delta \
        tag -l --sort=version:refname 'v3.0*'
  v3.0-alpha1
  v3.0-beta1
  v3.0
  v3.0-gamma1
  v3.0-delta1

Since 'versionsort.prereleaseSuffix' is not a fitting name for a
configuration variable to control this more general suffix reordering,
introduce the new variable 'versionsort.suffix'.  Still keep the old
configuration variable name as a deprecated alias, though, to avoid
suddenly breaking setups already using it.  Ignore the old variable if
both old and new configuration variables are set, but emit a warning
so users will be aware of it and can fix their configuration.  Extend
the documentation to describe and add a test to check this more
general behavior.

Note: since the empty suffix matches all tagnames, tagnames with
suffixes not included in the configuration are listed together with
the suffixless main release tag, ordered lexicographically right after
that, i.e. before tags with suffixes listed in the configuration
following the empty suffix.

Jeff King 7675c7bd01 t7810: avoid assumption about invalid regex syntax
A few of the tests want to check that "git grep -P -E" will
override -P with -E, and vice versa. To do so, we use a
regex with "\x{..}", which is valid in PCRE but not defined
by POSIX (for basic or extended regular expressions).

However, POSIX declares quite a lot of syntax, including
"\x", as "undefined". That leaves implementations free to
extend the standard if they choose. At least one, musl libc,
implements "\x" in the same way as PCRE.  Our tests check
that "-E" complains about "\x", which fails with musl.

We can fix this by finding some construct which behaves
reliably on both PCRE and POSIX, but differently in each
system.

One such construct is the use of backslash inside brackets.
In PCRE, "[\d]" interprets "\d" as it would outside the
brackets, matching a digit. Whereas in POSIX, the backslash
must be treated literally, and we match either it or a
literal "d".  Moreover, implementations are not free to
change this according to POSIX, so we should be able to rely
on it.

Richard Hansen d0e0cfe745 mergetool: fix running in subdir when rerere enabled
"git mergetool" (without any pathspec on the command line) that is
not run from the top-level of the working tree no longer works in
Git v2.11, failing to get the list of unmerged paths from the output
of "git rerere remaining".  This regression was introduced by
57937f70a0 ("mergetool: honor diff.orderFile", 2016-10-07).

This is because the pathnames output by the 'git rerere remaining'
command are relative to the top-level directory but the 'git diff
--name-only' command expects its pathname arguments to be relative
to the current working directory.  To make everything consistent,
cd_to_toplevel before running 'git diff --name-only' and adjust any
relative pathnames.

Stefan Beller 2d81c48fa7 pathspec: give better message for submodule related pathspec error
Every once in a while someone complains to the mailing list to have
run into this weird assertion[1]. The usual response from the mailing
list is link to old discussions[2], and acknowledging the problem
stating it is known.

This patch accomplishes two things:

  1. Switch assert() to die("BUG") to give a more readable message.

  2. Take one of the cases where we hit a BUG and turn it into a normal
     "there was something wrong with the input" message.

     This assertion triggered for cases where there wasn't a programming
     bug, but just bogus input. In particular, if the user asks for a
     pathspec that is inside a submodule, we shouldn't assert() or
     die("BUG"); we should tell the user their request is bogus.

     The only reason we did not check for it, is the expensive nature
     of such a check, so callers avoid setting the flag
     PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE. However when we die due
     to bogus input, the expense of CPU cycles spent outweighs the user
     wondering what went wrong, so run that check unconditionally before
     dying with a more generic error message.

Note: There is a case (e.g. "git -C submodule add .") in which we call
strip_submodule_slash_expensive, as git-add requests it via the flag
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE, but the assert used to
trigger nevertheless, because the flag PATHSPEC_LITERAL was not set,
such that we executed

	if (item->nowildcard_len < prefixlen)
		item->nowildcard_len = prefixlen;

and prefixlen was not adapted (e.g. it was computed from "submodule/")
So in the die_inside_submodule_path function we also need handle paths,
that were stripped before, i.e. are the exact submodule path. This
is why the conditions in die_inside_submodule_path are slightly
different than in strip_submodule_slash_expensive.

Jeff King 4e76832984 blame: output porcelain "previous" header for each file
It's possible for content currently found in one file to
have originated in two separate files, each of which may
have been modified in some single older commit.  The
--porcelain output generates an incorrect "previous" header
in this case, whereas --line-porcelain gets it right.  The
problem is that the porcelain output tries to omit repeated
details of commits, and treats "previous" as a property of
the commit, when it is really a property of the blamed block
of lines.

Let's look at an example. In a case like this, you might see
this output from --line-porcelain:

  SOME_SHA1 1 1 1
  author ...
  committer ...
  previous SOME_SHA1^ file_one
  filename file_one
          ...some line content...
  SOME_SHA1 2 1 1
  author ...
  committer ...
  previous SOME_SHA1^ file_two
  filename file_two
          ...some different content....

The "filename" fields tell us that the two lines are from
two different files. But notice that the filename also
appears in the "previous" field, which tells us where to
start a re-blame. The second content line never appeared in
file_one at all, so we would obviously need to re-blame from
file_two (or possibly even some other file, if had just been
renamed to file_two in SOME_SHA1).

So far so good. Now here's what --porcelain looks like:

  SOME_SHA1 1 1 1
  author ...
  committer ...
  previous SOME_SHA1^ file_one
  filename file_one
          ...some line content...
  SOME_SHA1 2 1 1
  filename file_two
          ...some different content....

We've dropped the author and committer fields from the
second line, as they would just be repeats.  But we can't
omit "filename", because it depends on the actual block of
blamed lines, not just the commit. This is handled by
emit_porcelain_details(), which will show the filename
either if it is the first mention of the commit _or_ if the
commit has multiple paths in it.

But we don't give "previous" the same handling. It's written
inside emit_one_suspect_detail(), which bails early if we've
already seen that commit. And so the output above is wrong;
a reader would assume that the correct place to re-blame
line two is from file_one, but that's obviously nonsense.

Let's treat "previous" the same as "filename", and show it
fresh whenever we know we are in a confusing case like this.

Jeff King ed58d8088b blame: handle --no-abbrev
You can already ask blame for full sha1s with "-l" or with
"--abbrev=40". But for consistency with other parts of Git,
we should support "--no-abbrev".

Worse, blame already accepts --no-abbrev, but it's totally
broken. When we see --no-abbrev, the abbrev variable is set
to 0, which is then used as a printf precision. For regular
sha1s, that means we print nothing at all (which is very
wrong). For boundary commits we decrement it to "-1", which
printf interprets as "no limit" (which is almost correct,
except it misses the 39-length magic explained in the
previous commit).

Let's detect --no-abbrev and behave as if --abbrev=40 was
given.

Jeff King 91229834c2 blame: fix alignment with --abbrev=40
The blame command internally adds 1 to any requested sha1
abbreviation length, and then subtracts it when outputting a
boundary commit. This lets regular and boundary sha1s line
up visually, but it misses one corner case.

When the requested length is 40, we bump the value to 41.
But since we only have 40 characters, that's all we can show
(fortunately the truncation is done by a printf precision
field, so it never tries to read past the end of the
buffer).  So a normal sha1 shows 40 hex characters, and a
boundary sha1 shows "^" plus 40 hex characters. The result
is misaligned.

The "-l" option to show long sha1s gets around this by
skipping the "abbrev" variable entirely and just always
using GIT_SHA1_HEXSZ.  This avoids the "+1" issue, but it
does mean that boundary commits only have 39 characters
printed.  This is somewhat odd, but it does look good
visually: the results are aligned and left-justified. The
alternative would be to allocate an extra column that would
contain either an extra space or the "^" boundary marker.

As this is by definition the human-readable view, it's
probably not that big a deal either way (and of course
--porcelain, etc, correctly produce correct 40-hex sha1s).
But for consistency, this patch teaches --abbrev=40 to
produce the same output as "-l" (always left-aligned, with
40-hex for normal sha1s, and "^" plus 39-hex for
boundaries).

Jeff King 965cba2e7e archive-zip: load userdiff config
Since 4aff646d17 (archive-zip: mark text files in archives,
2015-03-05), the zip archiver will look at the userdiff
driver to decide whether a file is text or binary. This
usually doesn't need to look any further than the attributes
themselves (e.g., "-diff", etc). But if the user defines a
custom driver like "diff=foo", we need to look at
"diff.foo.binary" in the config. Prior to this patch, we
didn't actually load it.

Johannes Schindelin 16615f0fbc mingw: add a regression test for pushing to UNC paths
On Windows, there are "UNC paths" to access network (AKA shared)
folders, of the form \\server\sharename\directory. This provides a
convenient way for Windows developers to share their Git repositories
without having to have a dedicated server.

Git for Windows v2.11.0 introduced a regression where pushing to said
UNC paths no longer works, although fetching and cloning still does, as
reported here: https://github.com/git-for-windows/git/issues/979

This regression was fixed in 7814fbe3f1 (normalize_path_copy(): fix
pushing to //server/share/dir on Windows, 2016-12-14).

Let's make sure that it does not regress again, by introducing a test
that uses so-called "administrative shares": disk volumes are
automatically shared under certain circumstances, e.g.  the C: drive is
shared as \\localhost\c$. The test needs to be skipped if the current
directory is inaccessible via said administrative share, of course.

David Turner bdf56de896 auto gc: don't write bitmaps for incremental repacks
When git gc --auto does an incremental repack of loose objects, we do
not expect to be able to write a bitmap; it is very likely that
objects in the new pack will have references to objects outside of the
pack.  So we shouldn't try to write a bitmap, because doing so will
likely issue a warning.

This warning was making its way into gc.log.  When the gc.log was
present, future auto gc runs would refuse to run.

Stefan Beller 55856a35b2 rm: absorb a submodules git dir before deletion
When deleting a submodule, we need to keep the actual git directory around,
such that we do not lose local changes in there and at a later checkout
of the submodule we don't need to clone it again.

Now that the functionality is available to absorb the git directory of a
submodule, rewrite the checking in git-rm to not complain, but rather
relocate the git directories inside the superproject.

An alternative solution was discussed to have a function
`depopulate_submodule`. That would couple the check for its git directory
and possible relocation before the the removal, such that it is less
likely to miss the check in the future.  But the indirection with such
a function added seemed also complex. The reason for that was that this
possible move of the git directory was also implemented in
`ok_to_remove_submodule`, such that this function could truthfully
answer whether it is ok to remove the submodule.

The solution proposed here defers all these checks to the caller.
