TracSpamFilter doesn't get Author or Content with 0.11dev

[johann@…]

When I go to /admin/spamfilter/monitor, I get a Traceback if the Author is None.

The attached patch fixes the problem.

The problem seems to be a symptom of a greater bug, maybe because I'm trying to use tracspamfilter with Trac 0.11dev r4612 and PostgreSQL as the database.

In the spamfilter_log table, the content is always "" (empty string) and the author is always NULL.

The headers are there (including Cookie: Host: Accept: etc). The columns authenticated, rejected, karma have reasonable values (mostly 0). The reasons column has appropriate data too. Path is always '/newticket' because that's where I tested it.

The problem persists after upgrade to r4665.

Also, the BadContent filter fails to work because the content is empty, but the Session filter works: sometimes a session is detected (with +3 karma).

The problem seems to be in the adapter that gets the content from Trac before filtering, not in the "INSERT INTO spamfilter_log" database SQL statement.

Therefore I assume it's not because of PostgreSQL but because of Trac 0.11dev.

Can you be more precise about the kind of data you were entering or the steps needed to reproduce the problem?

[johann@…]

Steps to reproduce the problem:

• Install Trac 0.11dev from Subversion
• Install Spam-Filter from Subversion as Egg in Trac environment (setup.py bdist_egg)
• Use sqlite or postgresql for database
• Run with tracd or Apache2 and mod_python
• Post a new ticket as anonymous (not logged in)
• Posting works, display gives a traceback (TypeError: len() of unsized object)
• In the database, the columns "author" and "content" will be empty.

SQLite version 2.8.17

I did this today, on a fresh system, using the following versions:

• ​http://svn.edgewall.com/repos/trac/sandbox/spam-filter [4508]
• ​http://svn.edgewall.org/repos/trac/trunk [4955]

[johann@…]

To be exact, in the database the author is NULL and the content is '' (empty string).

[johann@…]

The traceback that I mentioned above occurs in /admin/spamfilter/monitor and not on the regular ticket display.

The reason for the traceback is apparently that author is None, and len(None) gives a TypeError. My patch was trying to work around that, but it fixes only the symptom.

This was fixed in r4982. I've applied the changes from the patch, and fixed the reading of the old and new ticket values since the input names in the request changed in 0.11dev.
