Not a complete solution, but it's a start.  Craft a "svn mkdir" that includ=
es the url to test and a url that will always fail, e.g.
	svn mkdir -m "" http://server/repo/dir2test/a  http://server/repo/readonly=
/z

However, it looks like the urls are sorted and then processed in sort order=
 (including for svnmucc.)  So you need your test url to come before your "w=
ill always fail" readonly url.  Getting the sorting figured out is left an =
exercise to the reader.  Maybe someone else knows of a way to ensure that t=
he "always fail" readonly url gets checked last regardless of windows sorti=
ng, linux sorting, LC_ALL/LC_COLLATE settings, etc.

Subject: how to detect read-only branch from client?

I write a script getting sources from one repository, doing a build and oth=
er time consuming things and then committing the results into another repsi=
tory.

The problem is: the detination side is "managed" which means that I must ex=
pect read only branches there. They use the path based authentication featu=
re (see VisualSVNServer) without any communication. They want to close a br=
anch for commits, that's enough communication.

But in my case it would be very bad to start a process which runs for an ho=
ur or longer and then fails because it can't do the final commit.

How can I detect if a path in the destination directory is read only withou=
t modifying it?

My first guess was to use "svnmucc propdel" to delete a property which does=
n't exist. This works great on a branch which is read only. But on the othe=
r side it creates always a revision on normal branches. That's not good. Wh=
at can I do?
