Perl equiv for 'svn info http://example.com/repos'?
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I have some code that uses SVN::Client to connect to a subversion server
using http. I can do all of the usual things.. list files and folders
with their last authoer, revisions, size, etc, and read the contents of
files.
What I can't seen to figure out is how to get the current revisions of
that repository?
I thought that SVN::Repos would connect to it, and then is the
fs->revision_root...but it appears the SVNB::Repos::open doesn't like
http paths at all.
I'm trying to get the same information from the SVN perl modules that is
found by doing this:
> claco@NP5660:~/HandelFramework$ svn info http://handelframework.com/svn
> Path: svn
> URL: http://handelframework.com/svn
> Repository Root: http://handelframework.com/svn
> Repository UUID: 52a70e3a-55ec-0310-b14e-7917f69ecacc
> Revision: 901
> Node Kind: directory
> Last Changed Author: claco
> Last Changed Rev: 901
> Last Changed Date: 2005-10-24 20:31:03 -0400 (Mon, 24 Oct 2005)
Thanks.

libsvn_client is the C level library that corresponds to the perl
module SVN::Client. libsvn_ra is the C level library that corresponds
to SVN::Ra. Both of these generally communicate with the repository
over the network.
libsvn_repos and libsvn_fs are the C level libraries for talking
directly to a repository (in Perl that's SVN::Repos and SVN::Fs), they
give you a different kind of API, one that lets you do a lot of the
kind of things you're trying to do, but yes, you do have to be on the
same machine as the repository itself.

Yeah it does. But that seems to imple that while looping through a list
of items, I need to call log(itempath, itemrev, itemrev) on each one to
get it's last log.
If I have 100 items, that 100 more calls to the repo. That's can't be fast.
I could also call log([all,items,paths]), but what do I put in start/end
revision params since each item has a differen rev number?

I was getting that impression. It's not a major requirement, but it
would be nice.

OK, I'll bite. What's the difference between the first two, and the last
two in the big picture? Don't the first two imply that the repos viewer

Does SVN::Repos fall into that?

SVN::Client should have a log method of some sort.

People keep asking for this, but I have to admit I don't see why. All
any SVN::Client method that retrieves that data is going to be is just
a stupidly thin wrapper around the SVN::Ra method that retrieves it.

Well, unfortunately, I don't think you can actually get that data
without doing a bunch of calls to the repos.
Note that most repository viewer software uses the libsvn_repos and
libsvn_fs APIs, not the libsvn_client and libsvn_ra APIs. It's much
easier to do this sort of thing there, the APIs really are more suited
to it. It's kind of hard to do the stuff you're trying to do without
making a lot of calls because the client apps don't generally try to
do that sort of thing.

Where's that log method? on each dirent returned?
svn_dirent_t appears to only have:
kind, size, has_props, created_Rev, time, last_author... no log.
package _p_svn_dirent_t inherits Core, but it's not clear to me what
Core has really...
> bit easier to solve your problem if you explain exactly what you're

I'm trying to write a Model plugin for Catalyst to do basic browsing,
something along the lines of the Trac source browser. I could be
browsing a repo at http, svn://, or file://, but it's nothing to do with
working copies.
I can use Ra to get the uuid, root_rev..although, that would be nice in
SVN::Client too.
I'm currently using the SVN::Client to fetch the list of items in each
path. I'd like to get the last_log for each of the items too.
It's not too clear to me yet how to get all that info without making too
many calls to the repo.

I've love to..if I knew what the API really was without guessing. :-)

Well, ->ls should give you the last changed revision, so that should
be enough to use ->log to get you the log. I suspect it might be a
bit easier to solve your problem if you explain exactly what you're
trying to do though.

Well, there's nothing wrong with that (heck, we even provide the --xml
switch so you can get a parseable format), although if you do try to
do it via the perl API I'm sure patches to improve its documentation
would be more than welcome.

Yeah, I'll say. If you don't do C/XS, those docs aren't very helpful in
perlland.
The simplest thing
my $count = $ra->get_dir('/svn', $head);
I know there's a 3rd and 4th param, but what are they in perl-speak?
Passing \%hash or \@array get's nothing.
I get back a number. I have no idea how to actually get the contents.
SVN::Client works fine, but it's also a little unclear on how to get
svn:log props for each dirent returned from ->ls without making seperate
calls to get_prop for each item when looping through them.
At this point, I've be a little more productive just parsing the cmd
line client output. :-/

The stuff at quicksort.net is actually very out of date (I put it up
when I was originally converting the Subversion public headers to
Doxygen), you're better off with the stuff at:
http://svn.collab.net/svn-doxygen/

It's possible, although the higher level APIs in SVN::Client might be
more convenient. The SVN::Ra API is much more low level.

Seeing things like get_dir/get_file... I should be able to use SVN::Ra

Looking at svn_ra.h is probably the best place to start. Also, I
imagine the SVK source code contains a lot of use of it, so looking
there would be good.

SVN::Repos only works on local repositories. To get the latest
revision number for a remote repository you need to use SVN::Ra (the
repository access library). This is actually the example at the top
of SVN::Ra:
require SVN::Core;
require SVN::Ra;
my $ra = SVN::Ra->new ('file:///tmp/svmtest');
print $ra->get_latest_revnum ();
Just replace the 'file:///tmp/svmtest' part with the URL of your repository.
