Firstly, did you restart your device after installing Browser Switchboard? If not, try that before doing anything else.

If restarting doesn't help, then try the following:
  1. Upgrade to Browser Switchboard 3.1-2fremantle1. (This shouldn't solve your problem, but it will make finding the problem easier.)
  2. Open an X Terminal, then type the following, pressing Enter after each line (the $ is a prompt that will be displayed to you, not something you type):
    Code:
    $ killall browser-switchboard
$ browser-switchboard
    You should get output that looks something like this:
    Code:
    continuous_mode: 0
default_browser: 'fennec'
other_browser_cmd: 'NULL'
Starting main loop
  3. Try to open one of your home screen bookmarks.
  4. Assuming it doesn't work, copy all of the stuff Browser Switchboard writes to the xterm and post it here so that I can have a look at it.

Okay, can someone running Fremantle please try the following:
  1. Install or upgrade to 3.1-2fremantle1 (you could use an older release, but there'll be a lot more noise in the debugging output).
  2. Reboot the device.
  3. Start Browser Switchboard from an xterm or ssh session on the device:
    Code:
    $ killall browser-switchboard
$ browser-switchboard
  4. Open MicroB, then close all the MicroB browser windows.
  5. Post the output from browser-switchboard here, along with the output from "ps -ef | grep browser".

Thanks!

A N900? No, for reasons that have been discussed to death elsewhere on this forum. As for a future Fremantle or Harmattan device ... we'll have to see.

The fact that you're not getting an N900 but still doing all this work is nice.

Huh, so this actually (mostly) works properly for you? (You can check by setting the default browser to something other than MicroB and verifying that links open in that browser.)

Really puzzled by why the second browserd starts, though; what does "pidof /usr/sbin/browserd" show?

It does, actually. Just set the default to Tear, opened up MaePad and pressed "Visit website" in its About dialog box (and I know that it uses MicroB's D-Bus calls) and the correct site opened up in Tear. Set it to MicroB (without having any MicroB windows already open) and the "Visit website" link correctly opened in MicroB. This is with Browser Switchboard's default of "Lower memory usage".

~ $ pidof /usr/sbin/browserd
~ $ pidof browserd
2071 2051 1840 1797 1206
~ $

For reference:
1206 user 37712 S /usr/sbin/browserd -d
1797 user 39960 S /usr/sbin/browserd -d -b
1840 user 65372 S /usr/sbin/browserd -s 1840 -n RTComMessagingServer

2051 user 39964 S /usr/sbin/browserd -d -b

2053 user 29368 S browser
2071 user 55408 S /usr/sbin/browserd -s 2071 -n browserui
2149 user 2092 S grep browser

[No MicroB windows are visible on my screen; tho, I guess that some browserd's can be attributed to the preloading of the Conversations app which also uses a browserd for its interface]

Oookay, so now we have three browserd -d master processes -- it seems to be launching one for each time you start MicroB using Browser Switchboard. That's just odd -- "pidof /usr/sbin/browserd" doesn't return a nonzero exit code, by any chance?

EDIT: Okay, I see why that's happening, never mind -- we should be doing just "pidof browserd".

Even more strangely, we now have "browser" processes -- I'm guessing if you change the default browser back to something other than MicroB, links still open in MicroB? Do those browser processes quit if you run
Code:
dbus-send --session --type=method_call --print-reply --dest="com.nokia.osso_browser" /com/nokia/osso_browser/request com.nokia.osso_browser.exit_browser
? Any chance you can reproduce this (having browser processes open after launching MicroB with Browser Switchboard and then closing the browser windows) starting from a freshly booted device, and provide the debug output coming from browser-switchboard along the way?

Hm, okay, so that suggests that (1) browser-switchboard isn't picking up the cue to send the exit_browser method call, (2) MicroB doesn't always close in response to the exit_browser call, or (3) the method call is getting lost in transit.

Just rebooted; no attempts to open any browser.

Yet there seems to be a browser-switchboard running before you start one from the shell? Somewhat strange.

With continuous mode off, it's normal for browser-switchboard to exit after closing MicroB (and possibly trying to kill browserd), so I'm not sure why you had to Ctrl-C it here.

Bother; that supports idea (2) or (3) above ("Closing MicroB" should be printed right before the method call, and the error message comes from the attempt to kill browserd, which occurs after the method call is issued). I was hoping to avoid a straight kill() for fear of data loss, but it looks like we'll have to see if that works more reliably.

For Diablo users, Browser Switchboard 3.1-2 is now in Diablo extras (finally!) and on the Garage download page. The only change between 3.1-1 and this release is a small change to dependencies which shouldn't affect any users, and allows this release to land in extras. See the first post in the thread (now updated!) for details of the changes between 3.0 and this release.

For Fremantle users, Browser Switchboard 3.1-2fremantle2 is now on the Garage download page and in Fremantle extras-devel.

Changes between 3.1-2fremantle1 and 3.1-2fremantle2:
  • Make sure an already-running browserd is detected correctly; fixes a problem reported by qwerty12.
  • Be less polite about killing MicroB when we detect that the last browser window has closed; hopefully makes this a more reliable process.

MANY thanks to jukey and qwerty12 for providing the extensively detailed feedback which produced the changes in this release.

Hopefully the following should now work 100% of the time:
  1. Configure Browser Switchboard with any default browser other than MicroB.
  2. Restart the device.
  3. Open a link from an application or a desktop widget; the link should open in the default browser you configured.
  4. Open MicroB by using the Web menu entry (you don't need to change the default browser setting or restart the device).
  5. Open a link from an application or a desktop widget; the link should open in MicroB.
  6. Close all the MicroB browser windows.
  7. Open a link from an application or a desktop widget; the link should open in the default browser you configured.
  8. Open MicroB by using the Web menu entry (it should come up).

If anything doesn't work as expected along the way, please let me know; if you can, open an xterm, run "killall browser-switchboard; browser-switchboard", go through the sequence of steps, and then provide the output that browser-switchboard produces in the terminal when reporting your problem.

(If this release is still broken, I have one more trick up my sleeve; if that doesn't work, we'd need more drastic measures to make Fremantle MicroB play nicely with Browser Switchboard.)

Also, please report any problems you have with MicroB losing bookmarks, history, or settings when it's closed; the change to more heavy-handed measures for killing MicroB in this release may introduce such bugs.

TODO list before releasing 3.2 (mainly for my own benefit, but also useful if you're curious):
  • Finish making MicroB and Browser Switchboard behave nicely together on Fremantle. (should make it possible to push Browser Switchboard to Fremantle extras-testing)
  • Clean up the build system.
  • Refactor the launch_microb mess to make it more readable.
  • Introduce a more flexible logging system which allows logging to syslog, to make debugging intermittently occurring problems easier.
  • Make the "Web" menu entry launch MicroB and provide an alternate way of launching MicroB, to make the behavior more intuitive for new users (see this post for details).

TODO list post-3.2:
  • Do something intelligent when the user's configured browser isn't installed.
  • In the UI, don't let the user configure a browser that's not installed.
  • Provide a command-line tool for configuring browser-switchboard which can be used by browser developers to set their browser as the default.

I can't thank you enough for browser-switchboard, but at the same time I cannot forget that on a sane platform all this contortions shouldn't be necessary.
