REGRESSION (r27761-r27786): Cannot load RSS feeds using nightly build

• Component: New Bugs
• Status: RESOLVED WONTFIX

[Darren Collins]

RSS feeds are not displayed using Win32 Safari 3.0.4 with nightly WebKit builds between r27786 and r28023 (latest available). I get the following error message.

Safari can’t open the page “feed://news.netcraft.com/index.rdf”. The error was: “unknown error” (CFURLErrorDomain:305)

Example feeds tested are
feed://newsrss.bbc.co.uk/rss/newsonline_world_edition/front_page/rss.xml
feed://news.netcraft.com/index.rdf

This worked fine with Win32 Safari 3.0.4 r27761 and earlier.  I have not tested on non Windows platforms.

Confirmed with WebKit nightly build r28063 on Win XP SP2 and Safari 3.0.4 (523.12.9).  Works fine using Safari 3.0.4 directly.

I don't see any suspicious commits in the relevant range (r22761-r27786). Guess we have to look at the non-suspcious ones.

[Adam Roben (:aroben)]

Perhaps r27763 <http://trac.webkit.org/projects/webkit/changeset/27763>? It changed some ref-counting in a few places (made more use of Shared instead of hand-rolled ref-counting).

Darren, does this work again on recent nightly builds?

[Darren Collins]

Problem still 100% reproducible using recent nightlies r28503 and r28382 on WinXP.

I am seeing this as well.  Using Safari 3.0.4 (523.12.9) with original WebKit on Windows XP SP2, the feed loads fine.  With WebKit nightly r28503 (and the same software), I get a CFURLErrorDomain:305 error loading the feed.

Looks like a duplicate of bug 16035.

Thanks.  I knew there was a duplicate, but I couldn't find it last night.

[David Kilzer (:ddkilzer)]

This is a known incompatibility between current WebKit nightly builds and Safari for Windows 3.0.4 (with or without APPLE-SA-2007-12-17 Safari 3 Beta Update 3.0.4 Security Update).

I have documented the issue on the WebKit Wiki as well:

This is fixed when using Safari 3.1 for Windows.

I can still see the bug when running the latest nightly (as of today) against 3.1. 

Safari can’t open the page “feed://images.apple.com/main/rss/hotnews/hotnews.rss”. The error was: “unknown error” (CFURLErrorDomain:303) Please choose Report Bugs to Apple from the Help menu, note the error number, and describe what you did before you saw this message.

Yes, I still get the same error when testing nightlies against 3.1

I get the same error when testing nightlies (r31446) against 3.1.
