There would be more pages but these are just examples. http://www.hatena.ne.jp/ http://f.hatena.ne.jp/hotfoto The first one doesn't contain so many images but relatively many and the second one contains lots of images. I don't think this is the site specific issue. Regards, furaisanjin

We need find the issue for sure, but generally TCP_NODELAY should not cause any connection resets, so I think there is a bug somewhere that get's triggered by the different timing now.

Hi all. This may be FreeBSD (8.0R) specific or my local proxy specific but if src/IO/dpi.c contains TCP_NODELAY, I got lots of this error messages when the page contains lots of pictures. Http_connect_socket ERROR: Connection reset by peer so that several pictures aren't drawn. I agree that page rendering is much faster if TCP_NODELAY is set but that isn't good on my environment.

Yes, that's the question. I think the display stuff will need about three weeks until we can release it. If we want to release earlier I would leave it out. Cheers, Johannes

The matter of the display code prompts the question of where we want to draw a feature freeze line.

We might also want to cache SecretKey in a_Dpip_check_auth(). Cheers, Johannes

(and then there's also a title attr on the STYLE element) %coreattrs is part of %attrs, And what has %coreattrs or %attrs? Most things. As for behaviour, the spec says 'visual browsers frequently display the title as a "tool tip"'.

Is the title attribute allowed on all elements and always results in a tooltip? If so, we could rearrange things to parse common attributes in a special function.

Yah, I don't think it's CPU bound. There must be something else. I will have a look at it.
