TypeError: get_tagged_resources() takes exactly 3 arguments (2 given)

[Ryan J Ollos]

Running 0.7dev-r13797 of TagsPlugin, I tried to add the following to a wiki page:

[tag:bsd-license], [tag:apache-license], [tag:gpl-license], [tag:mit-license].

I cannot reproduce this for tag providers (ticket, wiki), that come bundled with the plugin.

By chance: Do you have any other plugin with its own, probably outdated ITagProvider implementation? I'll add some DEBUG logging to catch that with next (interim) changes.

[Ryan J Ollos]

The issue occurred on t-h.o. The first possibility that comes to mind is FullBlogPlugin. It seem to remember dealing with this issue in FullBlogPlugin a while ago. I'll check if our installation just needs an update.

Either way, your idea to log or possibly trap the error with a better message seems like a good one.

[Ryan J Ollos]

Installing FullBlogPlugin r13462 seems to have fixed the issue: tag:bsd-license. Thanks!

[Steffen Hoffmann]

In 13799:

TagsPlugin: Interim changes with DEBUG logging to catch flawed ITagProvider, refs #11658.

Nevertheless the signature for ITicketTagProvider.get_tagged_resources()
was incomplete - fixed.

[Steffen Hoffmann]

Extra effort for re-testing the older plugin with r13799 for confirmation of the interim fix would be welcome, but as I cannot find another obsolete ITagProvider implementation on t-h.o I wonder, if we really need that extra try-catch for production.

[Steffen Hoffmann]

Hm, extra robustness cannot hurt. I'll think it over, hear to your thoughts and decide tomorrow.

In 13800:

TagsPlugin: follow-up to r13799, fixed syntax error (refs #11658)

[Ryan J Ollos]

I tested with TagsPlugin 0.7dev-r13800 and FullBlogPlugin 0.1.1-r13461:

08:10:21 PM Trac[chrome] DEBUG: Prepare chrome data for request
08:10:22 PM Trac[api] DEBUG: Skip erroneous ITagProvider <tracfullblog.tags.FullBlogTagSystem object at 0x7fb5c8c52890>
127.

It works well, and seems to be useful for the cases that a user hasn't updated their FullBlogPlugin to r13462. It might be worthwhile to add a comment explaining the purpose of the try/except, and mention that it could eventually be removed.

[Steffen Hoffmann]

In 13802:

TagsPlugin: Log ITagProvider issue as warning, refs #11435 and #11658.

Since [13427] TagSystem.get_all_tags() requires stricter API conformance
of ITagProvider implementations regarding its get_tagged_resources method.
Own implementations have been fixed in [13461], but we keep the extra
'try-catch' from [13799-13800] for easier detection of the same issue with
other ITagProviders, namely versions of FullBlogPlugin before r13462.

In 13815:

TagsPlugin: Completing preparation for v0.7 release.

Availability of that code as stable, tagged release
closes #2429, #3359, #3610, #3624, #3677, #3754, #3864, #3947, #3983, #4078, #4277, #4503, #4799, #5523, #7787, #7857, #8638, #9057, #9058, #9059, #9060, #9061, #9062, #9063, #9149, #9210, #9521, #9630, #9636, #10032, #10416, #10636, #11096, #11147, #11152, #11274, #11302, #11658 and #11659.

Additionally there are some issues and enhancement requests showing progress,
but known to require more work to resolve them satisfactorily, specifically
refs #2804, #4200, #8747 and #9064.

Thanks to all contributors and followers, that enabled and encouraged a good
portion of this development work.
