Subject: gnome-shell-perf-tool: Fix various problems
X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~1013^2^2~5496
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=a21ddb591480f6e43ad1323c1bb16fbffe925969;p=gnome-shell.git

gnome-shell-perf-tool: Fix various problems

* Fix wrong parameter name to on_name_appeared callbacks
* optparse doesn't just leave extra command line arguments, it
  errors out, so don't try to pass through extra arguments -
  instead add explicit passthrough for '--replace'
* Fix usage of Gio.DBusProxy
* Add a default value for --perf so that if it's not supplied
  things don't die with a mysterious error message. (This wasn't
  needed when --perf enabled perf-mode)
