[AG-DEV] Running AG3 From CVS on RHEL4 Experiences

Just wanted to document my experiences with running AG3 from CVS on RH EL 4.

I started by downloading/installing all the pre-requisites, including rebuilding the wxPython rpms
from the wxPython site (to get the 2.6 versions).  Then I checked out the sources from CVS, cd'd
into AccessGrid/tools and ran 'python CvsSetup.py -a ..' as per the instructions at
http://www-unix.mcs.anl.gov/fl/research/accessgrid/software/cvs.html.

The rat build (main_control.c) failed citing 'conflicting types for snprintf'.  Looks like the
config script declared that snprintf wasn't available so it was redeclared/rewritten in the code via
an ifdef.   I just altered the ifdef to fail (and thus not redeclare) and the build worked.

Another problem was at the end of the build - there is a series of errors:
Generating Interfaces
sh: wsdl2py.py: command not found
sh: wsdl2py.py: command not found
sh: wsdl2dispatch.py: command not found

Upon investigation, there doesn't seem to be a wsdl2py.py on my system - including in the newly
built packages - however, /usr/bin/wsdl2py and /usr/bin/wsdl2dispatch (note no .py) do exist - so I
changed the GenerateInterfaces.py script exec variables to be wsdl2py and wsdl2dispatch and that
seemed to do the trick.

I then sourced the env-init.sh script and started VenueClient.py.

Up popped the Enter Profile Info dialog - I entered data pressed OK and it crashed:

File "/home/toddz/src/AccessGrid/AccessGrid/Jabber/JabberClient.py", line 86, in SendNameChange
    presence.from_ = self.currentRoomId + '/' + self.name
TypeError: cannot concatenate 'str' and 'NoneType' objects

Changed the declaration of self.name (line 26) from = none to = '' (str type).

Restarted VenueClient - now complained of a AttributeError: JabberClient instance has no attribute
'_stream' and upon checking, sure enough Line 20 shows _stream commented out.  I tried uncommenting
and ran in another error (about one of the parameters 'host' not being defined).

Since I was trying to set up a VenueServer and was only starting the VenueClient to test, I gave up
on my efforts and instead concentrated on getting the VenueServer running.

Ran CertificateManager.py and imported by ANL VenueServer service cert.

Then started VenueServer.py -d.  Here's the end of the trace:
Traceback (most recent call last):
  File "./VenueServer.py", line 144, in ?
    main()
  File "./VenueServer.py", line 98, in main
    context = Toolkit.Service.instance().GetContext()
  File "/home/toddz/src/AccessGrid/AccessGrid/Toolkit.py", line 217, in GetContext
    self.__context.load_verify_locations(capath=caDir)
  File "/usr/lib/python2.3/site-packages/M2Crypto/SSL/Context.py", line 121, in load_verify_locations
    return m2.ssl_ctx_load_verify_locations(self.ctx, cafile, capath)
TypeError: ssl_ctx_load_verify_locations() argument 2 must be string, not None


Changed line 217 in GetContext to read self.__context.load_verify_locations('', capath=caDir)

and the VenueServer started fine.

Only issue now is that I can't connect with the VenueManagement tool.... but I've already documented
that issue in my email to ag-dev from Feb 22.

Are these known issues?? I hate to file bug reports if the bug is caused by my (mis) configuration...

All of the pre-req's were taken from the AG download site and I'm running Python 2.3.4.


Thanks!

Todd
