wrong browser language in javascript

Bug Description

Binary package hint: epiphany-browser

Even if i've set italian as my default language the Javascript variable navigator.language is always 'en'.
This cause some italian sites show their english version to me rather then their default home page.

See for example www.beppegrillo.it, probably the most famous and visited italian blog.

Also putting an onload Javascript function like this:

 var language = '';
 if (navigator.appName == 'Netscape')
    language = navigator.language;
 else
    language = navigator.browserLanguage;

 if(language != 'X') show_english_version

appears to be a common pratice.

To reproduce the bug set italian language in preferences (i've not tested the behaviour with different languages) and open an html page containing:

<HTML>
<SCRIPT language=JavaScript>

function test()
{
 var language = '';
 if (navigator.appName == 'Netscape')
    language = navigator.language;
 else
    language = navigator.browserLanguage;

var fRet;
alert('language = ' + language);
}

</SCRIPT>
<BODY>
<a href=javascript:test(); >show language</a>
</BODY>
</HTML>

Then click the link.

No, Firefox 3 is not affected by this problem. It shows the page in the right language.

Do you have language-pack-gnome-it and language-pack-gnome-base-it installed?

OK, what do you see in Edit -> Preferences -> Language -> Languages ?

Please attach a screenshot if there is only en.

Well, i've already said in description that i've set italian language. To be more accurate i've tried either with the default gnome system language (it-IT) either choosing 'Italian' (and later 'Italian (Italy)') as default language expicitly in the Edit -> Preferences -> Language dialog. In all cases i've experienced the same behaviour.

Currently i've these languages in Edit -> Preferences -> Language (in this order):

Italiano (Italia)
Italiano
Lingue di sistema (it-it, it) // = System languages (i'dont know why, but language codes are entirely in lower case (eg. it-it and not it-IT), howewer i've reported them exactly as they are)

Hmm. Could you please try to set the matchOS setting in
/usr/share/epiphany-browser/default-prefs.js to "false" ?

e.g.

change

  pref("intl.locale.matchOS", true);

to

  pref("intl.locale.matchOS", false)

doesnt help either?

But changing "general.useragent.locale" from "en" to "it" in /usr/share/epiphany-browser/default-prefs.js
makes the browser show the right language in javascript, and so the right pages to me.

So could this be an epiphany issue? (maybe the language settings affects the http headers only?)

could you try to drop the complete setting line and see if it properly obeys the environment (given that you have the proper translation installed)?

e.g.
LANG=en_US epiphany => en
LANG=it epiphany => it

Thanks

Ok.

These are the step i've done. I'hope i've understended what i've to do.

My settings:
intl.locale.matchOS = true in both '/usr/lib/xulrunner-1.9/greprefs/all.js' and '/usr/share/epiphany-browser/default-prefs.js'
gnome language = it
epiphany preferences dialog language: it-IT
I see all my gnome apps in italian and also i've both language-pack-gnome-it and language-pack-gnome-base-it installed, so i guess i've the translation.

Now i've commented the line 'general.useragent.locale' in default-prefs.js
result: browser.language = en-US

Decommented and set 'general.useragent.locale' to en
result: browser.language = en

set 'general.useragent.locale' to it
result: browser.language = it

Well if i've understended your question the answer is: gecko browser.language depends only on 'general.useragent.locale' and no, it does not inherit the epiphany language preferences or the os/gnome default language.

Also i've done another test. I've dumped epiphany HTTP request header changing the language only in the epiphany preference dialog. The resoult is (as i've expected) that HTTP_ACCEPT_LANGUAGE field follow the setting. (en -> en, it -> it)

Sorry for my english (that's why i need a browser that makes me read in italian), however i hope these things are helpful.

thanks for testing this ... could you do this above and also comment it in
/usr/lib/xulrunner-1.9/defaults/pref/xulrunner.js

does that change anything?

If not, could you please attach a simple .html file as attachment that
displays the user agent language so i can try to develop a fix against
that testcase?

Neither this time it seems that something has changed.

With the line 'general.useragent.locale' commented in both
'/usr/lib/xulrunner-1.9/greprefs/all.js'
and
'/usr/lib/xulrunner-1.9/defaults/pref/xulrunner.js'
navigator.language remains en-US.

I've attached the .html.

For now it looks like the problem is that epiphany lacks some code to
auto update the proper field.

the test case above looks good (though i couldnt test it as i have no
real translations installed right now). Anyone can confirm this issue?

 affects ubuntu/epiphany-browser
 status confirmed

anyway, keeping xulrunner 1.9 open in case there is something to do
here in the end.
