'unicode' object has no attribute 'partition'

[hkunz@…]

Hi,

I upgraded from trac 0.10 to 0.11.1 Upgrading TracNav to 4.1 didn't work. I get

Error: Macro TracNav(TracNav/Main) failed

'unicode' object has no attribute 'partition'

thanks for any hints resolving this.

cheers, Hanspeter

I see the same issue. My setup is as follows:

• Fedora Core 4 on Amazon EC2
• Python 2.4
• Trac 0.11.1
• PostgreSQL 8.2
• Psycopg2
• TracNac installed via easy_install (version 4.1)

Every page with TracNav shows a:

Error: Macro TracNav(Manual/Toc) failed

'unicode' object has no attribute 'partition'

A little further research has revealed that this is a python 2.4 issue with TracNav. Line 129 of tracnav.py:

 for arg, _, values in map(lambda s: s.partition('='), args.split('|')):

The partition method is added to the string class as of Python 2.5 (as shown here: ​http://bytes.com/forum/thread537988.html among other places).

I guess Python 2.5 should be listed as a requirement or the above line should be rewritten to work without the partition method.

Update:

Being a little desperate I decided to hack this to work. I followed the steps below to make TracNav work with my Python 2.4 setup.

• Get the source from SVN
• Edit tracnav.py from line 129 - my file looks like this after edit

              #Commented out to ignore Python 2.4 issues
              #Using hardcoded config instead
              self.collapse = True
              self.modify = True
              self.reorder = True
  
              #for arg, _, values in map(lambda s: s.partition('='), args.split('|')):
              #    arg = arg.strip()
              #    if arg == 'nocollapse':
              #        self.collapse = False
              #    elif arg == 'noedit':
              #        self.modify = False
              #    elif arg == 'noreorder':
              #        self.reorder = False
              #    elif arg == 'allowed_macros':
              #        self.allowed_macros = map(lambda s: s.strip(), values.split(','))
              #    else:
              #        self.names.append(arg)
  
  

• Remove any old installs of TracNav
• Build and install the modified version

Note: This approach has the following drawbacks:

• No configuration possible from Trac
• You TOC MUST be at /wiki/TOC (this can possibly also be hardcoded..)
• Possibly others - I intent to use this only untill a fix is released or I upgrade to python 2.5

Hi guys, sorry for breaking backwards compatibility with Python 2.4.

Committed a fix in [3273], please test. You should be able to use

easy_install TracNav==dev

to install the development version.

Installed the newest development version - worked! excellent. Many thanks, Hp.
