How recently have you updated Djblets and Review Board? We put out a fix for this a
few days ago.

I can confirm this bug. Change of settings don't appear to do anything. If I access
same setting page again I get random results - either old one before change or new
one after change (sometimes even template error page). After restarting apache
everything is back to normal and changed settings are updated.

Sadly, no. There's still some issues that happen on occasion. I haven't figured it
out yet. I saw this just the other day.

So, I've been unable to reproduce this lately, and am wondering if it was fixed
through something else. If anyone else can reproduce this, please let me know your
exact configuration (web server, caching server, database type, mod_python/fastcgi, etc.)

Comment 9 by chipx86, Apr 04, 2009

I believe I found potential causes for this. There were ways of getting to stale
cached versions of a siteconfig, and we were definitely using these in places in our
code.

This should now be fixed in Djblets r12012.

Please comment if you still encounter this after tomorrow's (April 4, 2009) nightly.

I'm seeing this behavior on 1.5Beta 1. Restarting apache gets the settings to take
but without that many settings are not being saved when changed in the admin UI.

Comment 11 by chipx86, Mar 17 (2 days ago)

Yeah, it's definitely a bug in 1.5 beta 1, but I'd like to see if people still hit it
with the latest nightlies of both Review Board and Djblets.
