btnx: Send keyboard and mouse combination events with mouse buttons

[daou]

hey that looks nice *adds it to liferea*

edit: just did a clean uninstall as described above and installed 0.4.1, seems to work just fine however i now have 2 instances of btnx in the system monitor one with nice 0 and one with nice -2

It's possible the old btnx process is still running. The newer version of btnx should not allow multiple btnx processes running, but its possible the old version did not register itself to the PID file.

You can consider it a bug if you still have 2 btnx processes running after rebooting.

i did reboot after uninstalling and installing the new version (i wanted to see if the btnx loading error was gone - which it was)


edit:just did another reboot to confirm. still 2x btnx running :/

the same here

root@francois-desktop:/var/run# ps -fe | grep btnx
root 4316 1 0 13:24 ? 00:00:00 /usr/sbin/btnx -b
root 6014 1 0 13:24 ? 00:00:00 /usr/sbin/btnx -b

root@francois-desktop:/var/run# ls | grep btnx | xargs cat
6014

root@francois-desktop:/etc/btnx# cat /etc/udev/rules.d/99-btnx.rules
BUS=="usb", SYSFS{idVendor}=="046d", SYSFS{idProduct}=="c51a", ACTION=="add", RUN+="/etc/init.d/btnx start"
BUS=="usb", SYSFS{idVendor}=="046d", SYSFS{idProduct}=="c51a", ACTION=="remove",

with two process running :

root@francois-desktop:/etc/btnx# /etc/init.d/btnx stop
Stopping btnx : Button Extension - mouse button rerouter daemon
sed: impossible de lire /var/run/btnx.pid: Aucun fichier ou répertoire de ce type
btnx successfully stopped
root@francois-desktop:/etc/btnx# /etc/init.d/btnx stop
Stopping btnx : Button Extension - mouse button rerouter daemon
btnx successfully stopped
root@francois-desktop:/etc/btnx# /etc/init.d/btnx stop
Stopping btnx : Button Extension - mouse button rerouter daemon
btnx successfully stopped
etc.. Always one process running

my 2 cents : I think it's caused by the udev rules and the startup script not detecting other btnx running. or I don't know but Daou does

I'm not getting this problem. I have one btnx process running at a time. Is it a problem? Are you getting double events (both btnx's catch a button event and send keyboard combos)?

This is because of the udev rule, yes. The problem is with the MX Revolution mouse, because it registers itself to the system as 2 devices (one for the mouse, another just for the search button). udev runs the rule twice, and tries to start btnx twice. This is why I made the PID file, and forced btnx to kill all old processes found in that file. Then again, I'm not sure why one process isn't killing the other one.

Can you make sure it's not a zombie process?

I'm just not sure why I'm not able to reproduce this bug.

Yes, I did a reboot of my computer and a button event was catch 3 times (before it was 2) and only 2 btnx are running :

francois@francois-desktop:~$ ps -fe | grep btnx
root 4482 1 0 14:37 ? 00:00:00 /usr/sbin/btnx -b
root 6102 1 0 14:37 ? 00:00:00 /usr/sbin/btnx -b
francois 6597 6579 0 14:38 pts/0 00:00:00 grep btnx

francois@francois-desktop:~$ sudo /etc/init.d/btnx stop
[sudo] password for francois:
Stopping btnx : Button Extension - mouse button rerouter daemon
sed: impossible de lire /var/run/btnx.pid: Aucun fichier ou répertoire de ce type
btnx successfully stopped

francois@francois-desktop:~$ ps -fe | grep btnx
root 4482 1 0 14:37 ? 00:00:00 /usr/sbin/btnx -b
francois 6714 6579 0 14:41 pts/0 00:00:00 grep btnx

A button event is catched one time

francois@francois-desktop:~$ sudo /etc/init.d/btnx stop
Stopping btnx : Button Extension - mouse button rerouter daemon
btnx successfully stopped

francois@francois-desktop:~$ ps -fe | grep btnx
root 4482 1 0 14:37 ? 00:00:00 /usr/sbin/btnx -b
francois 6738 6579 0 14:42 pts/0 00:00:00 grep btnx



A button event is catched one time
sudo /etc/init.d/btnx stop is not able to kill the other process running (4482) because there is no PID file for it (ls /var/run | grep btnx shows nothing)

[daou]

Yes, I did a reboot of my computer and a button event was catch 3 times (before it was 2) and only 2 btnx are running :

I did a couple of reboots, still only one process for me. You are running 0.4.1?

You can try commenting out "do_stop" at lines 136 and 183 in the file "/etc/init.d/btnx"

If nothing seems to help, try disabling hot-plugging in the advanced settings tab of btnx-config.

francois12 and jamesford: could you test the new btnx in the SVN repository. I think I found and fixed the bug, but I can't test it myself.

If you have subversion installed, make a directory, check out the latest source from SVN, build btnx, and install it.

$ mkdir btnx-svn
$ cd btnx-svn
$ svn co http://svn.ollisalonen.com/btnx/trunk
$ cd trunk
$ make
$ sudo make install

Then test if it fixes the problem. I will release a new btnx version if it does. Thanks a lot for your time.

that's working great, thanks
how did you fix this?
keep up the good work man

Just removed one line from the source code . It was my mistake originally, but I didn't catch it because somehow it didn't cause a problem on my system.

But thanks, v.0.4.2 will be out soon.

ok, as I see the btnx.pid file shows now two pid's :

francois@francois-desktop:/var/run$ cat btnx.pid
7554 7596

something annoying is always here :

francois@francois-desktop:/var/run$ sudo /etc/init.d/btnx stop
Stopping btnx : Button Extension - mouse button rerouter daemon
/sbin/start-stop-daemon: warning: failed to kill 7554: No such process
sed: impossible de lire /var/run/btnx.pid: Aucun fichier ou répertoire de ce type
btnx successfully stopped
pid file is gone, the process is stopped
francois@francois-desktop:/var/run$ sudo /etc/init.d/btnx stop
Stopping btnx : Button Extension - mouse button rerouter daemon
btnx successfully stopped
francois@francois-desktop:/var/run$ sudo /etc/init.d/btnx stop
Stopping btnx : Button Extension - mouse button rerouter daemon
btnx successfully stopped
francois@francois-desktop:/var/run$ sudo /etc/init.d/btnx stop
Stopping btnx : Button Extension - mouse button rerouter daemon
btnx successfully stopped ETC..
