Websocket failure #75

benbrittain · 2014-09-18T22:43:52Z

I tried setting up sente myself, realized nothing was working, then ran the example. It still didn't work for some reason.

Chromes error message is more descriptive than FFx for the bug.

WebSocket connection to 'ws://localhost:39432/chsk' failed: One or more reserved bits are on:    reserved1 = 1, reserved2 = 0, reserved3 = 0 main.js:46260
WebSocket error: [object Event] main.js:44843
Chsk is closed: will try reconnect (8).

The text was updated successfully, but these errors were encountered:

Since the example also randomly does AJAX, here is that error as well. It gives a much more informative stack trace clj side

Hi Ben, thanks for the report. I'm struggling to reproduce this on my end.

Some questions (all in reference to the example project):

You're running the latest version of Sente ([com.taoensso/sente "1.1.0"])? Note that the README was incorrectly listing v1.0.0 as the most recent.
You're running the example project exactly as is, absolutely no modifications to project.clj or anything else?
What browser + version are you running?
Please run lein clean; lein cljsbuild clean and show me the output from lein deps :tree.

Will debug from there, thanks!

benbrittain · 2014-09-19T12:55:40Z

Sure thing!

Sente 1.1.0
I just downloaded the example project, I threw in a cider plugin dep, but it's the same without.
I tried with both chromium, and FFx 33.02a

ptaoussanis · 2014-09-19T14:17:27Z

Yeah, I'm really struggling to get a reproduction of this. Have tried:

Chrome 37.0.2062.94 (Ajax + WebSockets),
Safari 7.0.6 (9537.78.2) (Ajax + WebSockets),
FireFox 32.0 (Ajax + WebSockets).

There's nothing at all unusual about your platform? You're not running this on Heroku or a remote server of some kind? Any browser plugins that may be interfering with your connections?

Does anything here ring any bells for you?

Could you show me your lein clean; lein cljsbuild clean; lein deps :tree output from the reference example dir? (the lein deps :tree output you've got there seems to be from the Sente dir, not the ref example).

You're running the reference example as lein start-dev?

What OS are you on?

The Ajax error you're seeing doesn't make sense to me unless you're actually manually modifying the connected-uids_ atom, but the ref example doesn't do that. There's only two places where this atom is modified internally, and both maintain uids as sets.

On the off-chance that you've somehow ended up with corrupt code, could you try delete the following dirs before lein clean; lein cljsbuild clean; lein start-dev in the ref example dir again?:
~/.m2/repository/http-kit/http-kit/
~/.m2/repository/com/taoensso/

This'll delete your Maven artefacts for http-kit and everything by me so that they'll be pulled in fresh again on the next lein startup.

Thanks a lot for your help debugging this.

benbrittain · 2014-09-20T14:39:12Z

alright, exactly what I've done:

    rm -r ~/.m2/repository/http-kit
    rm -r ~/.m2/repository/com/taoensso
    cd workspace/sente/example-project
    lein clean; lein cljsbuild clean; lein start-dev

I'm generally a vim person, so maybe I've done something horrible with emacs here?

emacs
M-x cider-connect
(compile 'example.my-app)
(example.my-app/start!)

the lovely tree

Sorry about causing such problems! If there is any more info you need, lemme know.

Sorry about causing such problems!

Absolutely no problem, if there's an issue - I'd like to figure it out: thank you for providing data for debugging!

If there is any more info you need, lemme know.

Still haven't been able to reproduce, and still no idea what the cause could be, unfortunately. Ignoring the WebSocket error for the moment since that could be related to http-kit #95.

The Ajax error you're seeing shouldn't be possible and is on Sente's side, so let's try tackle that first:

I've just uploaded [com.taoensso.debug/sente "1.1.1-SNAPSHOT"] (please note the .debug).

Please grab a fresh copy of the new dev branch here which should include commit e06557a ("Temp: debug Websocket failure #75").
Start the example project as usual (lein clean; lein cljsbuild clean; lein start-dev from the /example-project dir).
Reload the example app in your browser until you get an :ajax connection (will say so in the js console).
If you're still seeing an error, please get me your js console & server log (there'll be extra debug info this time).

Much appreciated!

It was working. Then I authenticated and it broke?

for the websockets

ptaoussanis · 2014-09-22T05:17:41Z

Okay- we're getting somewhere!

2014-Sep-21 16:35:30 -0400 mars TRACE [taoensso.sente] - connected-uids_ change: taoensso.encore.Swapped@2a460b8f

This shouldn't be possible, and would explain the errors you're seeing for both WebSockets and Ajax. Let me dig into it and get back to you, I suspect I have all the info I need.

ptaoussanis · 2014-09-22T06:23:12Z

Okay, so this appears to be an AOT issue caused by your (compile 'example.my-app) call.

You can confirm this and get Sente to run correctly by:

Calling lein clean; lein cljsbuild clean; lein start-dev as usual.
M-x, cider-load-current-buffer instead of your compile call. (cider-load-current-buffer is usu. bound to C-c C-k, I believe).

I expect that everything should work from there.

As to why the compile call is causing issues - I can't actually say, I'll need to continue digging. The AOT compile call is causing some odd behaviour against one of Sente's supporting lib's types:

(defrecord Swapped [new-val return-val])
(instance? Swapped (Swapped.  "foo" "bar")) ; true before + after compile
(instance? Swapped (->Swapped "foo" "bar")) ; true before compile, false after

I'll do some more digging to understand better what about the AOT compile call is actually causing issues, but in the meantime I'd suggest just avoiding the compile call. I'll update the example docs in the meantime to explain how to eval a namespace in the usual way for folks unfamiliar with emacs+cider.

Thanks again for your assistance debugging, and please let me know if this does/doesn't resolve all the issues you were seeing. Cheers! :-)

This reverts commit e06557a.

ptaoussanis · 2014-09-22T07:17:20Z

Just updated [com.taoensso/sente "1.1.1-SNAPSHOT"] which I believe should work around the issue you've been seeing, even if you continue to use compile.

ptaoussanis · 2014-09-22T07:55:47Z

Seems like this may actually be a bug with Clojure: https://groups.google.com/forum/#!topic/clojure/LaTS7OFh01Q, http://dev.clojure.org/jira/browse/CLJ-979

ptaoussanis · 2014-09-26T12:07:22Z

Hey Ben, any follow-up on this?

benbrittain · 2014-09-27T21:32:22Z

Ahh, sorry. It does indeed work! Thanks so much!
