getting a repository's latest revision
Hi All,
I use ant scripts to build our applications for release. As part of this process, source
code is exported from the repository to a temporary directory and built.
In my ant script, this process often involves getting files from several different areas of
our repository and hence involves several "export" operations. To ensure I get a
consistent build, I use the same revision number for all my exports.
However, I've not been able to find any way of getting the "latest" revision number of
a repository without at least exporting one file from it. I've looked at the "svn info"
command, but this operates against a working copy which won't necessarily be
present on the build machine. So, for now, I do an export, parse its output for the
revision number and then use that revision number for subsequent exports. It works,
but I find it a bit messy and it is of course subject to any changes in the formatting of
the output from the export command.
I guess what I'm looking for is a kind of "svn revision URL" command that returns the
latest revision of the specified url without needing a local client working copy.
Alternatively perhaps, allow the "svn status" command to take a URL instead of a
local path and then return appropriate values for that URL.

Other folks have suggested how you might find that revision number, but
you could also try using svn:externals. This allows you to pull
different bits of your repository (or even multiple repositories) into a
single directory. There are minor wrinkles if you want to make changes
and commit them, but it sounds like you just want to do a build and not
commit anything back.

Cheers,
Mike.

Why not just check out all the projects at once by making a list of them
in the arguments.
svn co -r "HEAD" http://websvn.your.domain/trunk/proj1 \
http://websvn.your.domain/trunk/proj2 etc.....
I'm not sure if this will check out the same version of "HEAD" if
someone checks in a change to a project during the checkout command's
runtime. Maybe someone else can clear that up if svn's commands are
atomic.
If "HEAD" can change during your check out. You could check out one
project, find the repository version number using Steve Williams method
or the `svnversion` program and then check out the rest of the projects
using that as the -r argument.
I think that should do it.
Cheers,
Chris

Hi Rob,
I had the same problem but with the java binding not the commandline client.
Meanwhile I learned how to extend the libsvn_client API and the
commandline client. The latter to make debugging easier.
If you are willing to do some C programming I can give you some pointers
on how to make the command line client do what you want.
Regards,
Dirk

Thanks for the quick reply - I was not aware of that nuance of the use of the list
command, though it's there in the documentation once you know. However, when I
tried it against one of our project URLs, it returned a list of all the subfolders under it
with the latest revision of each. Parsing that in Ant would be tricky :-(. I tried the -N (-
-non-recursive) switch, but the list command won't take that.

svn ls -v URL
gives you the latest revision of the URL without a local working copy.

svn log -r head URL
gives you an entry like:
