CLIENT SIDE JAVASCRIPT ERROR with IE 9

[mwuttke]

Hello,

I am using etherpad-lite v1.2.7 and get the following error by using IE 9 on Windows, when I open a tab in the browser with a new or named pad:

[ERROR] console - CLIENT SIDE JAVASCRIPT ERROR: {"errorId":"NSjIPJqJAsfor6BmB9X1","msg":"The operation could not be continued due to the following error: c00ce56e.","url":"http://localhost/etherpad/socket.io/socket.io.js","linenumber":2,"userAgent":"Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; BRI/2; InfoPath.3)"}

With locate I find these two files: /var/lib/nodejs/node-apps/etherpad-lite/src/node_modules/socket.io/node_modules/socket.io-client/dist/socket.io.js /var/lib/nodejs/node-apps/etherpad-lite/src/node_modules/socket.io/lib/socket.io.js

The installation of etherpad is baesd on the github-code from git://github.com/ether/etherpad-lite.git. I am using node.js v0.8.18, npm v1.2.2, Apache2 & MySQL5. etherpad-lite is running as a service.

When I try my site with other browsers under Win/Lin/MAC everything is fine. When I try your site demo.etherpad.org, everything is fine with IE 9 under Windows.

Please can you help me? What did I wrong in the configuration of etherpad-lite?

Thank you for your help! Michael

[JohnMcLear]

Strange..

Try

rm -rf src/node_modules
bin/build.sh

That we re-install Socket.IO

Just FYI in some browsers it's dangerous to test stuff on /localhost/ because of the way that cookies and sessions work

[mwuttke]

Sorry, but I don't have a file bin/build.sh only bin/installDeps.sh

I have replaced my hostname by localhost. ;-)

Thank you, Michael

[update] I made a reinstall, but same same! ;-(

[JohnMcLear]

Sorry, I meant bin/run.sh !! My mistake..

[mwuttke]

Hello John, I did it like you proposed.

/etc/init.d/etherpad-lite stop rm -rf src/node_modules bin/run.sh

But with the same result. I've got the same error message in the IE browser.

Here you can find the log: http://pastebin.com/s4R4HaaW

Thank you for your help! Michael

[2013-02-01 21:02:16.739] [WARN] message - Authentication try failed:{"component":"pad","type":"CLIENT_READY","padId":"test","sessionID":null,"password":null,"token":"t.5XBRvD9TPbMX7vjndTPh","protocolVersion":2}

Why are you trying to authenticate?

Did you modify your settings.json away from the template?

[mwuttke]

Hello John,

I am using etherpad-lite together with moodle. I installed moodle on one server and etherpad-lite on an other server. For the connection between both installations I use the moodle plugin from goldquest/moodlehu [1] and try to allow the access of etherpad-lite pads only thru moodle.

My modifications of the settings.json are:

• "title": "Etherpad Lite @ ... ",
• "ip": "x.x.x.x",
• "dbType": "postgres", dbsettings: ...
• "defaultPadText" : "something in german ...",
• "requireSession" : true,
• "editOnly" : true,
• "abiword" : "/usr/bin/abiword", &
• I commented out the basic user-authentication part.

Thank You for your help! Michael

[update]: Both sites run with https.

[1] https://github.com/moodlehu/moodle-mod_etherpadlite

[JohnMcLear]

Etherpad is behaving properly by the looks of things. If you change requireSession to false I assume everything is fine?

Also RE commenting out basic user auth part, doesn't that break functionality when requireSession is set to true? Try comment that back too.

From the logs it looks like https://github.com/moodlehu/moodle-mod_etherpadlite doesn't create a session, I'd create an issue there..

[mwuttke]

Hello John,

sorry but I've got still the same error message in the IE 9. I re commenting out the basic user auth part and changed requireSession to false. And restarted etherpad-lite.

Here ist the log-output: snipp [2013-02-12 14:53:37.310] [INFO] http - 304, GET /p/g.UVp625VFzlJvren2$moodlelms [2013-02-12 14:53:37.323] [DEBUG] socket.io - served static content /socket.io.js [2013-02-12 14:53:37.383] [INFO] http - 307, GET /javascripts/lib/ep_etherpad-lite/static/js/colorutils?callback=require.define [2013-02-12 14:53:37.390] [INFO] http - 200, GET /javascripts/lib/ep_etherpad-lite/static/js/ace2_inner.js?callback=require.define [2013-02-12 14:53:37.474] [DEBUG] socket.io - authorized [2013-02-12 14:53:37.474] [INFO] socket.io - handshake authorized 'KOLaSPdr4lxMQBzcp6NX' [2013-02-12 14:49:21.539] [ERROR] console - CLIENT SIDE JAVASCRIPT ERROR: {"errorId":"Z9CxCmwLHvvknTFkbvAs","msg":"Der Vorgang konnte aufgrund des folgenden Fehlers nicht fortgesetzt werden: c00ce56e.","url":"http://myhosturl/etherpad/socket.io/socket.io.js","linenumber":2,"userAgent":"Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; BRI/2; InfoPath.3)"} snapp

Is there somthing wrong with my server-configuration or with env. settings of node,js/npm or ehterpad-lite?

Thanks a lot, Michael

[JohnMcLear]

try a clean install and if that doesn't work try git checkout develop

Are you clearing your browser cache each time? IE9 is a pig at holding browser caches.

[mwuttke]

Ok, I will try the complete reinstall tomorrow.

My path is now /var/lib/nodejs and /var/lib/nodejs/node-apps/etherpad-lite.

yes cleared th browser cache each time! ;-)

Thanx, Michael

[mwuttke]

Hello John,

sorry but same same. I made a complete reinstall of nodejs/nmp & installed the etherpad-lite develop branch.

Here is the error-message again: snipp [2013-02-13 16:59:10.788] [ERROR] console - CLIENT SIDE JAVASCRIPT ERROR: {"errorId":"StSKnMTlOJUQ6WMfw5bD","msg":"Der Vorgang konnte aufgrund des folgenden Fehlers nicht fortgesetzt werden: c00ce56e.","url":"http://localhost/etherpad/socket.io/socket.io.js","linenumber":2,"userAgent":"Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; InfoPath.3)"} snapp

And with a FF under Linux it works fin but in the log-file I found the following message: snipp [2013-02-13 17:02:56.375] [ERROR] console - CLIENT SIDE JAVASCRIPT ERROR: {"errorId":"l3CncYUQjVaxDumKBHBM","msg":"Script error.","url":"http://localhost/etherpad/javascripts/lib/ep_etherpad-lite/static/js/pad.js?callback=require.define","linenumber":0,"userAgent":"Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:18.0) Gecko/20100101 Firefox/18.0"} [2013-02-13 17:02:56.376] [INFO] http - 200, POST /jserror snall

Do I have to check the start-script and the sites-eneabled-config for etherpad for errors?

Thank you! Michael

[JohnMcLear]

It shows MSIE7 in your crash report..

You reported IE9...

[mwuttke]

Hello John,

sorry, but I used the compatibility mode of the IE 9 to test the pad. I also tested the pad with different Windows machines and with different browser versions of IE. But I've got always the same error as above.

Thank you! Michael

[JohnMcLear]

Can you paste the new error without IE9 in IE compatibility mode please?

[mwuttke]

Hello John,

here is the error output of the IE 9 without any compatibility mode:

[JohnMcLear]

Try turn minify to false and set maxAge to 0 in settings.json

Restart and see what error you get.

Also play with the available transports in settings.json

[mwuttke]

hi John,

I set minify to false & maxAge to 0 in the seetings.json, but nothing really changed, only the linenumber:

Thank you! Michael

[JohnMcLear]

I notice you aren't running Etherpad on root, does it help if you don't try to rewrite?

Please stop testing through apache btw.

Did changing your transports in settings.json help at all?

[mwuttke]

Hello John,

Sorry, but not to rewrite did not help and I can't use nginx in my server environment.

What do you mean exactly with changing the transport-config?

Thanx, Michael

[JohnMcLear]

Please paste the error you get when you don't rewrite through apache

See https://github.com/ether/etherpad-lite/blob/develop/settings.json.template#L104 -- You could try to play with removing values from this array.

[marcelklehr]

Best start by removing "xhr-polling"..

[mwuttke]

Hello John, Hello Marcel,

At first I played with the transport methods xhr-polling, jsonp-polling & htmlfile by removing one value after the other.

But but unfortunately without any success.

Then I turned of the rewrite rule of the apache config. And this was the result:

From time to time the service hung: [2013-02-22 15:19:53.090] [DEBUG] socket.io - setting request 'GET' '/socket.io/1/xhr-polling/DQ9fV3yw1jNQQI80Q6KY?t=1361542792975' [2013-02-22 15:19:53.090] [DEBUG] socket.io - setting poll timeout [2013-02-22 15:19:53.090] [DEBUG] socket.io - discarding transport [2013-02-22 15:19:53.090] [DEBUG] socket.io - cleared close timeout for client 'DQ9fV3yw1jNQQI80Q6KY' [2013-02-22 15:19:56.720] [DEBUG] socket.io - clearing poll timeout [2013-02-22 15:19:56.724] [ERROR] console - Error: socket hang up at createHangUpError (http.js:1360:15) at ServerResponse.OutgoingMessage._writeRaw (http.js:507:26) at ServerResponse.OutgoingMessage._send (http.js:476:15) at ServerResponse.OutgoingMessage.write (http.js:749:16) at XHRPolling.doWrite (/var/lib/nodejs/node-apps/etherpad-lite/src/node_modules/socket.io/lib/transports/xhr-polling.js:67:17) at XHRPolling.HTTPPolling.write (/var/lib/nodejs/node-apps/etherpad-lite/src/node_modules/socket.io/lib/transports/http-polling.js:132:8) at XHRPolling.Transport.packet (/var/lib/nodejs/node-apps/etherpad-lite/src/node_modules/socket.io/lib/transport.js:515:15) at Object.

Thanks for your help, Michael

[update]: I am still on the develop branch of epl.

[disy-mk]

Are you using node.js v0.8.20?

[mwuttke]

Yes.

[disy-mk]

This seems to be the same as #1541 I guess...

Don't want to state that this is a duplicate of the mentioned issue, but the reason for the behavior might be the same...

[disy-mk]

when you reported the error first it you must have been using node.js v.0.8.19, because v0.8.20 was released like one week ago... did anything change regarding the log? Maybe try to go back to 0.9.19 with you actual settings (without rewrite rule) and check again.

[marcelklehr]

switch back to 0.8.19 ;)

[mwuttke]

Ok I switched back to node version 0.8.19 and turned of the rewrite rule again. Now the server dont crash anymore but the rest is still same same. See below:

[marcelklehr]

"sessionID":null suggests that the session cookie isn't set/transmitted

[mwuttke]

What should I do?

[marcelklehr]

Set the cookie? Or check where the cookie is set and whether it's set correctly (eg for the correct domain and path)

[mwuttke]

Hi,

How can I set the cookie or check if the cookie is set?

These are the settings: node v0.8.19 epl develop branch rewrite on apache2 is of "requireSession" : true, "editOnly" : true, "minify" : false, "maxAge" : 0, "abiword" : "/usr/bin/abiword", "requireAuthentication": false, "requireAuthorization": false, "socketTransportProtocols" : ["jsonp-polling", "htmlfile"]

Hello John,

you are right! ;-)

Now I've installed the latest version of etherpad-lite (git version is 14f9c91) based on debian wheezy, node.js version 0.10.30/np version 1.4.21 and postgresql version 9.3 together with moodle (+ etherpad-lite plugin for moodle and remove_embed).

And: Everything seems to work as expected. Also using etherpad-lite via moodle with IE 11, FF 31 or Opera 12 under Windows 7. ;-)

IE 9 we don't have any more

Thanks a lot for the great work! Michael
