Reports returns no rows in RSS format

[ipa@…]

Short example: ​http://trac.edgewall.org/report/1?format=rss&USER=anonymous

returns no rows at all against:

​http://trac.edgewall.org/report/1

which returns lots of rows.

I'm not sure it is expected behaviour or bug, because i.e. Custom query report works ok.

Hmm. Strange. Something must have happened at some stage, because there really isn't anything there. And, of course there should be. The t.e.o site runs on 0.11.5rc1 - we should have a 'version' tag for it, but bumping version to 0.11-stable as it occurs in currently latest code.

The raw RSS body I get back looks like this:

<?xml version="1.0"?>
<rss xmlns:dc="http://purl.org/dc/elements/1.1/" version="2.0">
  <channel>
    <title>The Trac Project: {1} All Active Tickets</title>
    <link>http://trac.edgewall.org/report/1</link>
    <description>Trac Report - </description>

    <generator>Trac v0.11.5stable-r8335</generator>
  </channel>
</rss>

Anyone got a clue? A regression following some recent changes?

Even stranger, I cannot reproduce this in my 0.11-stable checkout, using the exact same report as on t.e.o. But then again, I don't have 931 tickets in that report.

[Remy Blank]

The number of tickets doesn't seem to have an influence, though. Even {12}, in my case with 37 matches, doesn't show anything in the RSS feed. I wonder if there's anything in the logs about this…

For me that problem appears in 0.11.4 build

I really cannot reproduce this, so it might be an InstallationIssue on t.e.o. Do we have a custom report.rss template here?

Mmh, works fine here with 0.11.4 as well. Do you have a site-specific report.rss template? Any errors in your log (crank it up to DEBUG level, if possible)?

[ipa@…]

There are no special templates. After debug I've got something like that:

I can reproduce this and it seems to be a regression in Genshi 0.6dev (t.e.o is using 0.6dev-r999 and I'm using advanced-i18n ​[G1060]).

I have a workaround, which also makes the code cleaner.

[Christian Boos]

Fixed in r8452. The Genshi regression is tracked in ​#G327.

There seem to be no other places where this expression construction is used in the templates.
