reset.c: extract function for parsing arguments
reset: don't allow "git reset -- $pathspec" in bare repo
reset.c: pass pathspec around instead of (prefix, argv) pair
reset $pathspec: exit with code 0 if successful
reset $pathspec: no need to discard index

Specifically the fields uid, gid, ctime, ino and dev are set to zero
by JGit. Other implementations, eg. Git in cygwin are allegedly also
somewhat incompatible with Git For Windows and on *nix platforms
the resolution of the timestamps may differ.
Any stat checking by git will then need to check content, which may
be very slow, particularly on Windows. Since mtime and size
is typically enough we should allow the user to tell git to avoid
checking these fields if they are set to zero in the index.
This change introduces a core.checkstat config option where the
the user can select to check all fields (default), or just size
and the whole second part of mtime (minimal).

Unlike other commands that take both revs and pathspecs without "--"
disamiguators only when the boundary is clear, "git grep" treated
what can be interpreted as a rev as-is, without making sure that it
could also have meant a pathspec. E.g.
$ git grep -e foo master
when 'master' is in the working tree, should have triggered an
ambiguity error, but it didn't, and searched in the tree of the
commit named by 'master'.

:/abc may mean two things:
- as a revision, it means the revision that has "abc" in commit
message.
- as a pathpec, it means "abc" from root.
Currently we see ":/abc" as a rev (most of the time), but never see it
as a pathspec even if "abc" exists and "git log :/abc" will gladly
take ":/abc" as rev even it's ambiguous. This patch makes it:
- ambiguous when "abc" exists on worktree
- a rev if abc does not exist on worktree
- a path if abc is not found in any commits (although better use
"--" to avoid ambiguation because searching through commit DAG is
expensive)
A plus from this patch is, because ":/" never matches anything as a
rev, it is never considered a valid rev and because root directory
always exists, ":/" is always unambiguously seen as a pathspec.

Although 2to3 will fix most issues in Python 2 code to make it run under
Python 3, it does not handle the new strict separation between byte
strings and unicode strings. There is one instance in
git_remote_helpers where we are caught by this, which is when reading
refs from "git for-each-ref".
Fix this by operating on the returned string as a byte string rather
than a unicode string. As this method is currently only used internally
by the class this does not affect code anywhere else.
Note that we cannot use byte strings in the source as the 'b' prefix is
not supported before Python 2.7 so in order to maintain compatibility
with the maximum range of Python versions we use an explicit call to
encode().

Subversion 1.7 and newer implement HTTPv2, an extension that should make HTTP
more efficient. Servers with support for this protocol will make the subversion
client library take an alternative code path that checks (with assertions)
whether the URL is "canonical" or not.
This patch fixes an issue I encountered while trying to `git svn dcommit` a
rename action for a file containing a single quote character ("User's Manual"
to "UserMan.tex"). It does not happen for older subversion 1.6 servers nor
non-HTTP(S) protocols such as the native svn protocol, only on an Apache server
shipping SVN 1.7. Trying to `git svn dcommit` under the aforementioned
conditions yields the following error which aborts the commit process:
Committing to http://example.com/svn ...
perl: subversion/libsvn_subr/dirent_uri.c:1520: uri_skip_ancestor:
Assertion `svn_uri_is_canonical(child_uri, ((void *)0))' failed.
error: git-svn died of signal 6
An analysis of the subversion source for the cause:
- The assertion originates from uri_skip_ancestor which calls
svn_uri_is_canonical, which fails when the URL contains percent-encoded values
that do not necessarily have to be encoded (not "canonical" enough). This is
done by a table lookup in libsvn_subr/path.c. Putting some debugging prints
revealed that the character ' is indeed encoded to %27 which is not
considered canonical.
- url_skip_ancestor is called by svn_ra_neon__get_baseline_info with the root
repository URL and path as parameters;
- which is called by copy_resource (libsvn_ra_neon/commit.c) for a copy action
(or in my case, renaming which is actually copy + delete old);
- which is called by commit_add_dir;
- which is assigned as a structure method "add_file" in
svn_ra_neon__get_commit_editor.
In the whole path, the path argument is not modified.
Through some more uninteresting wrapper functions, the Perl bindings gives you
access to the add_file method which will pass the path argument without
modifications to svn.
git-svn calls the "R"(ename) subroutine in Git::SVN::Editor which contains:
326 my $fbat = $self->add_file($self->repo_path($m->{file_b}), $pbat,
327 $self->url_path($m->{file_a}), $self->{r});
"repo_path" basically returns the path as-is, unless the "svn.pathnameencoding"
configuration property is set. "url_path" tries to escape some special
characters, but does not take all special characters into account, thereby
causing the path to contain some escaped characters which do not have to be
escaped.
The list of characters not to be escaped are taken from the
subversion/libsvn_subr/path.c file to fully account for all characters. Tested
with a filename containing all characters in the range 0x20 to 0x78 (inclusive).

Add support for a pre-push hook which can be used to determine if the
set of refs to be pushed is suitable for the target repository. The
hook is run with two arguments specifying the name and location of the
destination repository.
Information about what is to be pushed is provided by sending lines of
the following form to the hook's standard input:
<local ref> SP <local sha1> SP <remote ref> SP <remote sha1> LF
If the hook exits with a non-zero status, the push will be aborted.
This will allow the script to determine if the push is acceptable based
on the target repository and branch(es), the commits which are to be
pushed, and even the source branches in some cases.

When a single SVN repository is split into multiple Git repositories
many SVN revisions will exist in only one of the Git repositories
created. For some projects the only way to build a working artifact is
to check out corresponding versions of various repositories, with no
indication of what those are in the Git world - in the SVN world the
revision numbers are sufficient.
By adding "--before" to "git-svn find-rev" we can say "tell me what this
repository looked like when that other repository looked like this":
git svn find-rev --before \
r$(git --git-dir=/over/there.git svn find-rev HEAD)

Subversion's canonical URLs are intended to make URL comparison easy
and therefore have strict rules about what characters are special
enough to urlencode and what characters should be left alone.
When in the fallback codepath because unable to use libsvn's own
canonicalization function for some reason, escape special characters
in URIs according to the svn_uri__char_validity[] table in
subversion/libsvn_subr/path.c (r935829). The libsvn versions that
trigger this code path are not likely to be strict enough to care, but
it's nicer to be consistent.
Noticed by using SVN 1.6.17 perl bindings, which do not provide
SVN::_Core::svn_uri_canonicalize (triggering the fallback code),
with libsvn 1.7.5, whose do_switch is fussy enough to care:

When pushing to update a branch with a commit that is not a
descendant of the commit at the tip, a wrong message "already
exists" was given, instead of the correct "non-fast-forward", if we
do not have the object sitting in the destination repository at the
tip of the ref we are updating.
The primary cause of the bug is that the check in a new helper
function is_forwardable() assumed both old and new objects are
available and can be checked, which is not always the case.
The way the caller uses the result of this function is also wrong.
If the helper says "we do not want to let this push go through", the
caller unconditionally translates it into "we blocked it because the
destination already exists", which is not true at all in this case.
Fix this by doing these three things:
* Remove unnecessary not_forwardable from "struct ref"; it is only
used inside set_ref_status_for_push();
* Make "refs/tags/" the only hierarchy that cannot be replaced
without --force;
* Remove the misguided attempt to force that everything that
updates an existing ref has to be a commit outside "refs/tags/"
hierarchy.
The policy last one tried to implement may later be resurrected and
extended to ensure fast-forwardness (defined as "not losing
objects", extending from the traditional "not losing commits from
the resulting history") when objects that are not commit are
involved (e.g. an annotated tag in hierarchies outside refs/tags),
but such a logic belongs to "is this a fast-forward?" check that is
done by ref_newer(); is_forwardable(), which is now removed, was not
the right place to do so.
