AttributeError: 'NoneType' object has no attribute 'get_path_url' after enabling ContextMenuPlugin.*

[Matthew.Wild@…]

After installing and enabling the ContextMenuPlugin and looking at the 'Browse Source' page, I get this error

Trac detected an internal error:
AttributeError: 'NoneType' object has no attribute 'get_path_url'

The trace is

I can reproduce. I hope to have a fix available shortly.

[Ryan J Ollos]

I'm going to check-in some code that cleans things up. However, I'm not sure what is causing your problem, and I probably haven't fixed it yet. Could you send the details from trac.ini or webadmin page of how you configured your repositories?

[Ryan J Ollos]

(In [12116]) Refs #10439:

• The Subversionlink is not shown in the context menu if the URL is not set for the repository.
• Some code refactoring.
  • Modified entry point.
  • Extracted some common code into get_repository_path_and_rev.
  • The repository is now obtained from the data dictionary passed to ITemplateStreamProvider.filter_stream(...).

(In [12117]) Refs #10439: Moved license description from source files to the added COPYING file.

[Ryan J Ollos]

I can reproduce in the case that the repository is not correctly configured. I'll add some code to protect against that. Please report back if the latest revision is working for you now.

The Wiki Link (to copy) functionality doesn't appear to have been finished. I don't see any code for copying the data to the clipboard. We can work on that in another ticket.

[Ryan J Ollos]

(In [12126]) Refs #10439:

• Check if repository object exists before trying to call a method of it. This should protect against tracebacks when the repository is not correctly configured.
• Refactoring:
  • Removed some unused imports.
  • Replaced use of deprecated add_javascript with add_script.
  • Finished moving license text, which was started in [12117].

The repository is set up using direct-svnfs as the svn is only served via http.

Yes, the latest version seems to work, at least it doesn't crash!

Unfortunately, I don't actually get any of the buttons on the 'Browse Source' page once I add the TracBrowserSvnOperations plugin, which is why I needed the ContextMenuPlugin.

This may be because of the use of direct-svnfs to access the repository.

[Ryan J Ollos]

Okay, let me test with your configuration and get back to you. Could you post the repositories and trac sections of your trac.ini? Do you have only a single repository?

Yes, just the single repository.

Refocusing.
