974720 - Pandora.com broken with HTTP cache v2

Status: RESOLVED WORKSFORME

(Core :: Networking: Cache, defect)

Description

[Stephen Donner [:stephend] Not actively reading bugmail]

Build identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:30.0) Gecko/20100101 Firefox/30.0

STR:

1. With the latest nightly (https://hg.mozilla.org/mozilla-central/rev/bf0e76f2a7d4) on Windows 7, load http://www.pandora.com
2. Log in, try to play music

Actual Results:

"It's taking too long to load..."

Expected Results:

Just Works (tm)

I've found that if I disable/set browser.cache.use_new_backend_temp to |false|, this Just Works (tm) -- same build, no need for restart, etc.

This is interesting!  Are able to provide an NSPR log of the device?

(Pandora doesn't work when accessed out of US.)

Stephen, can I ask you one more favor?  Since I actually cannot reproduce from here (unless I have a proxy at US) can you also produce a NSPR log while the new cache is off?  Please keep the same scenario/steps, I'd like to do a line by line compare then and see where we deviate.

Thanks!

Here's a logfile with the same STR, but with browser.cache.use_new_backend_temp set to |false| (and Pandora works).

Honza, I don't know how complex Pandora's networking is, but we could certainly setup a squid proxy for you in the US.  Or you could use a VPN?

Jason, proxy would be great.  I'm not sure how to use our VPN for this, AFAIK, the MV VPN has no external internet access.

Will track this for now due to impact to our users.

The cache2 trial has ended - cache2 is now disabled on Nightly again.  Before we do it again or enable for real, this will be fixed.

So, despite all information I got from Stephen (thanks for it!), I cannot reproduce at all.  I installed most of the extension Stephen reported to me he had installed, also set the prefs influencing http and cache.  No change, I still can load pandora.com content correctly.

Stephen, it could be some extension - you have a lot of them installed, I think it's a conflict.  Would you be willing to turn them one by one off and check which it could be?

I'll attach a logfile of it happening, yet in Safe Mode.

Stephen, any news?  

Actually, only thing I'd like to ask you is to *send me your prefs.js file* (feel free to send privately to my bugzilla mail.)

Thanks.

@ Honza- Stephen is out on PTO. I'll email you to see if I can get you what you need.

Apologies for the delay -- on protracted, family matters -- I can't reproduce this, any longer, using the identical profile as before, given the latest trunk build(s): http://www.screencast.com/users/stephendonner/folders/Jing/media/f625cc86-52c9-4c66-9a2c-07ccddb0650b

Thanks.  Just let you know we turned the new cache off again.
