Bug 79325 – REGRESSION: Messages do not go through on groupme.com

• Component: Page Loading
• Status: RESOLVED FIXED

[George Thomas]

When trying to respond to members of my groupchat on groupme.com, messages do not go through.  When I try with firefox it does work.

[Alexey Proskuryakov]

Did this start with a nightly build, or is it broken in Safari 5.1.3, too?

[George Thomas]

It works on Safari, but does not work on the nightly build.

What do you  mean by "messages do not go through"? Can you be more specific about the effect?

[George Thomas]

If i type in a response to a chat on groupme when chatting with my groups the message i send doesn't go through, but when i use firefox or safari it does go through.  Does that make sense? It's kind of like a chat client, just my chat messages fail to go through when using webkit.

Apparently this was regressed by https://bugs.webkit.org/show_bug.cgi?id=76564

Nate, did you have a chance to check what causes this?

Will try to do so today.

Does anyone have a test account for groupme that I could borrow? I'd rather not use my personal mobile phone, and I don't have a work/test one handy.

Alternatively, I can try to contact groupme and see if they can set me up with a test account.

Got an account. Haven't immediately been able to repro, but still looking.

Still no luck reproducing. Did you do anything specific before the messages stopped appearing? E.g., repeating the same message multiple times, reloading, etc?

I wondered if this might have been the same cause as https://bugs.webkit.org/show_bug.cgi?id=80551, but I've yet to reproduce with or without the fix for that issue.

Ah, I think I get it now. Sending a message with ToT WebKit makes it appear locally, but if you have the chat open in another window, it won't appear.

It is surprising that this is the fix for this bug if the recession happened in r108576.

I'm sure that you tested that this helps, but I'm curious about the mechanics.

Does this fix also address bug 80764?

Thank you autocorrection :)

Did it really work between 107859 and 108576? I would be surprised, but the loader has produced stranger bugs.

As it stands now, we can make a GET request to a url, then a POST, and the MemoryCache will still try treat it as a cache hit. That was the problem I saw on groupme, but maybe there was more than one.

I suspect so, since I think this is the fix I should have been making in the first place. I can mark that and probably some others as dupes, or I can use those bugs as an excuse to improve test coverage (I'm inclined toward the latter).

Looking at our testing notes more carefully, it's unclear why we decided that this regressed in r108576. Probably a regression from r107672 indeed.
