566673 - Atom feeds on http://hg.mozilla.org/ do not have etags or last-modified headers, wastes resources

Status: RESOLVED FIXED

(Developer Services :: Mercurial: hg.mozilla.org, defect)

Description

[LegNeato]

I have a script that reads the RSS feeds on http://hg.mozilla.org. I want to respect etags and last-modified so that I don't hammer the server yet can have data that is reasonably up to date. It doesn't look like the server gives me the headers I need, here's a dump from python:

{'date': 'Tue, 18 May 2010 18:43:24 GMT', 'transfer-encoding': 'chunked', 'connection': 'close', 'content-type': 'application/atom+xml; charset=UTF-8', 'server': 'Apache/2.2.3 (Red Hat)'}

I want my script to check the etags and/or last-modified so it doesn't need to pull down the entire feed to see if anything has changed.

It looks like the build system polls and could be enhanced if etag/last-modified was available (http://hg.mozilla.org/build/buildbotcustom/file/8b1380cbf092/changes/hgpoller.py)

I think you should file this upstream with Mercurial:
http://mercurial.selenic.com/bts/

Those feeds are generated by hgweb, which is part of Mercurial. We don't have any customization of them.

Looks like it is already at http://mercurial.selenic.com/bts/issue1845

Upstream bug, will pick up when we update hg.

That upstream bug got fixed, and I see etag in the regular hgweb feeds, and the pushlog feeds now.
