Subject: icecat "mailto" handler does not work - and cannot be reconfigured by user
Date: Mon, 25 Jul 2016 09:34:40 +0200 [thread overview]

Whoops. I should have read the page better.
However, clicking on that button in icecat does not send E-Mail for me.
Monitoring the network interface I can see that it redirects to a mailto: URL. So that's nice.
Checking the application preferences of icecat, it only gives "always ask" (note: it doesn't ask) and not an application for "mailto". (in GuixSD)
Creating my own HTML page with a mailto link doesn't work either.
Therefore, I reported a bug to Guix too.
Bug report follows:
"mailto:" links don't work in icecat.
Checking the icecat source code, there are several ways to handle E-Mail. One of them is as "external helper app". One of those (not sure whether it's the correct one) uses gio's g_app_info_launch_default_for_uri in order to launch helper applications.
There is a test icecat-38.8.0/uriloader/exthandler/tests/unit/test_handlerService.js that does:
let isLinux = ("@mozilla.org/gio-service;1" in Components.classes);
if (isLinux) {
// Check mailto handler from GIO
// If there isn't one, then we have no mailto handler
let gIOSvc = Cc["@mozilla.org/gio-service;1"].
createInstance(Ci.nsIGIOService);
try {
gIOSvc.getAppForURIScheme("mailto");
noMailto = false;
} catch (ex) {
noMailto = true;
}
}
And this ./toolkit/system/gnome/nsGIOService.cpp uses g_app_info_launch_default_for_uri .
Therefore, I tried it out:
#include <glib.h>
#include <gio/gio.h>
#include <stdlib.h>
int main() {
GError* error;
g_app_info_launch_default_for_uri("mailto:foo@example.com", NULL, &error);
// g_app_info_launch_default_for_uri("http://www.google.at/", NULL, &error);
if (error) {
g_warning("err %s", error->message);
g_error_free(error);
return 1;
} else
return 0;
}
I get:
** (process:12464): WARNING **: err Operation not supported
If I debug it some more I get:

There would be g_app_info_set_as_default_for_type () to set a new default application in nsGIOService - which is exposed and used by ./browser/components/shell/nsGNOMEShellService.cpp on setting icecat up as default browser (so not always).
I'm using Fluxbox.
