Relying on SVN::Core::INVALID_REVNUM (-1) as the "start"
argument to SVN::Ra::get_log() proved unreliable with http(s)
URLs so the result of SVN::Ra::get_latest_revnum() is used as
the "start" argument instead.

For the case of multiple projects sharing a single SVN repository, it is
common practice to create the standard SVN directory layout within a
subdirectory for each project. In such setups, access control is often
used to limit what projects a given user may access. git-svn failed to
detect branches (e.g. when passing --stdlayout to clone) because it
relied on having access to the root directory in the repository. This
patch solves this problem by making git-svn use paths relative to the
given repository URL instead of the repository root.

This enables git-svn.perl to read multiple 'branches' and 'tags' entries in
svn-remote config sections. The init and clone subcommands also support
multiple --branches and --tags arguments.
The branch (and tag) subcommand gets a new argument: --destination (or -d).
This argument is required if there are multiple branches (or tags) entries
configured for the remote Subversion repository. The argument's value
specifies which branch (or tag) path to use to create the branch (or tag).
The specified value must match the left side (without wildcards) of one of
the branches (or tags) refspecs in the svn-remote's config.

'git svn dcommit' takes an optional revision argument, but the meaning
of it was rather scary. It completely ignored the current state of
the HEAD, only looking at the revisions between SVN and $rev. If HEAD
was attached to $branch, the branch lost all commits $rev..$branch in
the process.
Considering that 'git svn dcommit HEAD^' has the intuitive meaning
"dcommit all changes on my branch except the last one", we change the
meaning of the revision argument. git-svn temporarily checks out $rev
for its work, meaning that
* if a branch is specified, that branch (_not_ the HEAD) is rebased as
part of the dcommit,
* if some other revision is specified, as in the example, all work
happens on a detached HEAD and no branch is affected.

SVN tries to store all commit messages in UTF-8, however it is
up to the job of the clients to enforce this rule. SVN servers
themselves do not always enforce this; allowing clients to

So git-svn will enforce this and tell the user to set

Add a new option, --authors-prog, to git-svn that allows a more flexible
alternative (or supplement) to --authors-file. This allows more
advanced username operations than the authors file will allow. For
example, one may look up Subversion users via LDAP, or may generate the
name and email address from the Subversion username.
Notes:
* If both --authors-name and --authors-prog are given, the former is
tried first, falling back to the later.
* The program is called once per unique SVN username, and the result is
cached.
* The command-line argument must be the path to a program, not a generic
shell command line. The absolute path to this program is taken at
startup since the git-svn script changes directory during operation.
* The option is not enabled for `git svn log'.

When initializing a git-svn repository from a Subversion repoository,
it is common to be interested in a path which did not exist in the
initial commit to Subversion. In a large repository, the initial fetch

the user receives no additional feedback. Print the highest revision

This will be useful when somebody want to checkout something partially from

Modules are interdependent, and you want it to be single repostory (to commit
to all modules simultaneously and view complete history), but do not want
branches and tags be checked out into working copy.
Other use case is excluding some large blobs.
The quirk for now is that user must specify this option every fetch/rebase;

The get_log() function in the Perl SVN API introduced the limit
parameter in 1.2.0. However, this got discarded in our SVN::Ra

the limit functionality in older SVN versions by preventing the
original callback from being called if the given limit has been
reached. This emulation is less bandwidth efficient, but SVN
1.1.x is becoming rarer now.
Additionally, the --limit parameter in svn(1) uses the
aforementioned get_log() functionality change in SVN 1.2.x.
t9129 no longer depends on --limit to work and instead uses
Perl to parse out the commit message.

This is a followup to 7fc35e0e94,
(workaround a for broken symlinks in SVN).
Since broken SVN clients can commit svn:special files without
the magic "link " prefix, this can affect delta application
when we update the broken svn:special file. So now we fall
back and retry the delta application on symlinks if having
a "link " prefix fails.
Our behavior differs from svn(1) (v1.5.1) slightly:
When a svn:special file is created w/o a "link " prefix, svn
will create a regular file (mode 100644 to git) with the
contents of the blob as-is.
Our behavior is to continue creating the symlink (mode 120000
to git) with the contents of the blob as-is. While this
differs from current svn(1) behavior, this is easier and more
efficient to implement (and the correctness of the svn(1) is
debatable, since it's a workaround for a bug in the first
place).
