DirectPydsUriTest

As DirectPydsUriTest points out, I should capture outbound pyds:/ links and redirect them appropriately. [Fixed.]

Backslashes in Wiki node titles

When I first made EmptyParentNodeTest, I accidentally used backslashes to separate the ID. That caused problems because the code I was using to separate the names worked (_fullSplit), but the subsequent name lookups I was performing after recomposing with '/' didn't. I need to automatically translate them, or at least issue an appropriate warning. [Fixed.]

Empty Title Test

I should automatically fill in the titles of new Wiki nodes. I've added EmptyTitleTest to track it. [Done.]

New bug!

I was trying to post a new Wiki node (EmptyParentNodeTest), and...

Exception exceptions.NameError: 
global name 'getPost' is not defined

PyDS\Tool.py 967 process_request 
u = getattr(tool,meth)(req) 

PyDS\WikiTool.py 569 edit_redir 
id = self.addNode(id, title, text, template=int(template)) 

PyDS\WikiTool.py 699 addNode 
meshTool.renderItemsWithUnresolvedLinks() 

PyDS\MeshTool.py 986 renderItemsWithUnresolvedLinks 
return [handles, self.renderItems(handles)] 

PyDS\MeshTool.py 1015 renderItems 
method(item.uniqueId) 

PyDS\WeblogTool.py 325 renderItemByUniqueId 
post = getPost(uniqueId) 

Fix:

# Render an item by its unique ID
def renderItemByUniqueId(self, uniqueId):
        """Render all pages associated with the post identified by `uniqueId`."""
        post  = self.getPost(uniqueId)
        # ... and so on

I've got no idea why renderItemsWithUnresolvedLinks was triggering weblog renders. I should also look into that.

Psyco vs PyDS

Anyone tried using Psyco with PyDS? I'm thinking it might be especially handy for rendering reStructuredText...

[later] I've tried it out, and it speeds up reST on the example in StructuredText.py by a good 40%. Just for fun, I've changed pyds-start to load Psyco. I'm posting from it now. :)

Still trying to nut out this local rendering problem in WeblogTool...

I thought I was on to something, but WeblogTemplate.tmpl does indeed refer to the local rendering.

AHA! Fixed. New code at the bottom of ReferToWeblogPost.

That'll do me for the night, I reckon. :)

Aha!

My problem with Wiki uploads (see P111) turned out just to be a problem with the templates. Georg, you need to catch that Cheetah.NameMapper.NotFound exception and throw up something nicer...

Now, why can't I force a refresh? Or, assuming I can: why is my call to PyDS.Tool.debugOutput not working? [Cough. look in error.log, silly!]

I don't get the render problem

Following on from P111; if I hit the Status page I get a report on the size of the StoryTool render queue. Maybe it's there now?

Can't Upstream Wiki Changes

[This turned out to be a lot simpler than it looked. See P113.]

wiki is throwing:

First Bug to Fix: Refer To Weblog Post (again)

Now, all links go to external. Oops. See: ReferToWeblogPost. I swear that wasn't the case when I was last writing code for PyDS.

PyDS back up on 0.7.3

Righto. Let's start experimenting again.
