1292586 - [e10s] Firefox Nightly Can't load Gzipped files

Status: RESOLVED FIXED

(Core :: Networking: HTTP, defect, P2)

Description

[Chris DeCairos (:cade)]

Attachment: Screenshot from 2016-08-05 10-57-19.png

Firefox Nightly (51, updated on the mornging of August 5th 2016) Appears to have become incapable of loading GZipped files.

STR:
 
1. Using the version of nightly above visit: https://d2rqpywgspga97.cloudfront.net/static/53253f8/css/b8611c350d3c.css.gz
2. Notice that the CSS file is just garbled text.

If you do the same in stable or another browser, it should be decompressed into valid CSS

I included a screenshot - Nightly is on the left, Firefox 47 running on the right.

I'm also experiencing this.

Gonna hunt down a regression range.

Comment 2

[Tracy Walker [:tracy]]

This works for me with latest Nightly builds:

Win7: Nightly 51.0a1, 20160805030444
Mac 10.11: Nightly 51.0a1, 20160805030444
Ubuntu 14.04: Nightly 51.0a1, 20160805030444

Chris, can you reproduce in safemode?

[Mike Conley (:mconley) (:⚙️) (PTO June 8 - 12)]

Interestingly, I can't reproduce this with a clean profile, so there's something about our configuration that's exposing this.

Anyhow, I used my default profile to regression-hunt, and drilled it down to:

https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=d22b099cf1e312edf24adc27dd23541b37900cfe&tochange=e1f3ed984607e209ab9ba3a4892b58d3d03b9430

Bug 1261585 looks like the obvious suspect.

Hey Dragana, any idea what's going on? I'll post my about:support in a sec.

[Chris DeCairos (:cade)]

When I start up nightly in safe mode, the bug disappears.

Comment 6

[--]

I can repeat it in my nightly, and if I just open a non-e10s window and paste the link there - it works!

Comment 7

[Dragana Damjanovic [:dragana]]

I know what is wrong and how to fix it. Thanks.
If you remove an addon that uses nsITraceableChannel it will work too :).
I will have a patch soon.

My patch from bug 1261585 was only considering extension that need the external app helper service, but the thing is more complicated, especially I was missing once that do not need the helper, like text:
https://hg.mozilla.org/mozilla-central/diff/9b2a99adc05e/uriloader/base/nsURILoader.cpp#l224
I do not want to duplicate all of that so I decided to move the decision to the child and suspend parent in mean time

Thanks.  The link tho doesn't point to any useful.. whatever you wanted to show.

I must point out that this is made only when there is a tracable listener added.  Is there any addon that may add it on every or significant number of channels?  Because this will have a performance impact.  Instead of queuing OnStart/OnData*/OnStop fast on the IPC wire, we must wait for the response from the child to resume the real parent channel.  IPC rtt is small (on machines I test with - i.e. fast) but still this would be a regression.

this will be easy to forget when we add some new |return| here.  could we have some Auto class or something a bit smarter?

when you do this, it must be in tight sync with what you then send down as the contentDecodingWillBeCalledOnParent arg!  I see this bit missing somehow in this patch.  Probably the reason why try tests mostly time out.

Comment 15

[Honza Bambas (:mayhemer)]

Honestly, if this turns out to be too much pain, I'd rather back bug 1261585 out and WONTFIX it.  We could provide tools to apply conversions easily in the consumer's implementation (provide indicators when and what type of conversion may needed to be used).

Let's back out bug 1261585 and i will do this in a different way.

Comment 19

[Wes Kocher (:KWierso) (Not reading bugmail; email directly if needed)]

Backed bug 1261585 out of central and aurora. 

I'll leave it to you to decide if this bug should be closed. :)

[Dragana Damjanovic [:dragana]]

This is resolved by backing out bug 1261585.

Comment 21

[Ritu Kothari (:ritu) (Inactive, please n-i to RyanVM, jcristau, or pascal)]

We don't need to track this anymore as the backouts are already done.
