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.

The support we offer these use cases is not very friendly to the end

- Don't do it. Avoid such a line by rewrapping or indenting; and
- Use --cleanup=whitespace but remove all the hint lines we add.
Give them a way to set a custom comment char, e.g.
$ git -c core.commentchar="%" commit
so that they do not have to do either of the two workarounds.

Commit a469a10 wraps some error calls in macros to give the
compiler a chance to do more static analysis on their
constant -1 return value. We limit the use of these macros
to __GNUC__, since gcc is the primary beneficiary of the new
information, and because we use GNU features for handling
variadic macros.
However, clang also defines __GNUC__, but generates warnings
with -Wunused-value when these macros are used in a void
context, because the constant "-1" ends up being useless.
Gcc does not complain about this case (though it is unclear
if it is because it is smart enough to see what we are
doing, or too dumb to realize that the -1 is unused). We
can squelch the warning by just disabling these macros when
clang is in use.

argument every time diff is to be used is impractical. Moreover,
creating an alias doesn't play nicely with other tools based on diff
(git-show for instance). Hence, a configuration variable which is able
to set specific algorithm is needed. For now, these four values are
accepted: 'myers' (which has the same effect as not setting the config
variable at all), 'minimal', 'patience' and 'histogram'.

Instead, keep track of the previous character in a separate

i == 0 correctly.
* Make the two loops over the string look as similar as possible to
make it more obvious that the count computed in the first pass
agrees with the true length of the new string written in the second
pass. As a side effect, this makes it possible to use the "j"
