JavaHL info2 problem

[Marcin Porwit]

Hi,

I'm running into a problem with the info2 call in the 1.6 JavaHL library. I am 
attempting to use this to fake password validation for a user, so if this is a 
bass-ackwards way of doing things, please let me know. I issue two calls to 
svnclient.info2. The first one does an info2 on the local, checked out 
directory, and the callback stores the serverUrl (gotten using the getUrl() 
call). I get the correct value:
http://10.0.62.148/svn/myproject
The second call then does an svnclient.info2 on the serverUrl. This second call 
throws a ClientException:
2012-08-27 15:21:57,446 [main] ERROR P42svnMain - 
com.salesforce.cheetah.p42svn.SubversionRepositoryException: Could not validate

If I do an svn info from the command line, it works fine:
mporwit-wsl[script]$ svn --username p42svn info 
http://10.0.62.148/svn/myprojectAuthentication realm:  
myproject subversion repository
Password for 'p42svn':

ATTENTION!  Your password for authentication realm:

    myproject subversion repository

can only be stored to disk unencrypted!  You are advised to configure
your system so that Subversion can store passwords encrypted, if
possible.  See the documentation for details.

You can avoid future appearances of this warning by setting the value
of the 'store-plaintext-passwords' option to either 'yes' or 'no' in
'/home/mporwit/.subversion/servers'.

So I'm confused as to why info2 is failing. It seems to be dropping the last 
element of the path, which is another thing I'm confused about. Pointers to 
what I am doing wrong are appreciated, as would be pointers on how to better 
validate a user password prior to doing a commit on the repo.

I'm not subscribed to the mailing list, so an explicit CC would be greatly 
appreciated.

Thanks,

Marcin

Re: JavaHL info2 problem

Hi Mark,

I'm calling the non-deprecated version of info2:
http://subversion.apache.org/docs/javahl/1.7/org/tigris/subversion/javahl/SVNClientInterface.html#info2(java.lang.String,
 org.tigris.subversion.javahl.Revision, org.tigris.subversion.javahl.Revision, 
int, java.lang.String[], org.tigris.subversion.javahl.InfoCallback)

You're right in that it looks like it is treating the URL as a local file 
system path… and yes, I'm passing in null for both the Revsion and pegRevision 
arguments.  What should I be passing in instead? The svn info from the command 
line does not take a revision -- does it pass one in implicitly?

My first call to info2 uses the local file system path:
svnclient.info2(destdir, null, null, 0, null, infoCallback);

The second call to info2 uses the server URL I got from the first info2 call:
svnclient.info2(serverURI, null, null, 0, null, infoCallback);

The actual infoCallback is as follows:
class InformationCallback implements InfoCallback {
private SubversionRepository repo;

InformationCallback(SubversionRepository repo) {
this.repo = repo;
}

public void singleInfo(Info2 info) {
repo.setServerURI(info.getReposRootUrl());
}

}

Thanks,

MKP
