Description

I am getting really weird, seemingly random glitches from the Pydoc plugin.

Things like it will say that no documentation is found for a file, but if I refresh a few times it might show me the docs, and then go back to "not found" the next time I load the page.

Below is a traceback from on of the common errors. This error will also sometimes show up on a wiki page if I have used a [pydoc:] link on it. 

Traceback (most recent call last):

As a partial work around, I have set up the GeneralLinkSyntax plugin to provide the [pydoc:foo] wiki syntax (to /pydoc/%s)

Your version seems to be modified, line 322 of tracpydoc.py is 

return '<a class="wiki" href="%s">%s</a>' % \
	   (formatter.href.pydoc(), label)

Can you revert to trunk and try again?

  • owner changed from alect to athomas.
  • status changed from new to assigned.

Try this patch, it unloads each module after it generates the documentation:

  • tracpydoc/tracpydoc.py

    old new  
    237237            return "No Python documentation found for '%s'" % target 
    238238 
    239239    def _makedoc(self, target, visibility): 
     240        already_imported = sys.modules.copy() 
    240241        module, object = self.load_object(target) 
    241242        try: 
    242243            self.makedoc_lock.acquire() 
    …… 
    263264            else: 
    264265                return self.doc.document(object) 
    265266        finally: 
     267            for modname in sys.modules.copy(): 
     268                if modname not in already_imported: 
     269                    self.env.log.debug("Unloading module %s" % modname) 
     270                    del(sys.modules[modname]) 
    266271            self.makedoc_lock.release()

Do you get this issue with anything other than pygame?

That patch didn't seem to help.

My install is here, so you can look around to see whats happening.
