Gui bugs collection

[lneuhaus]

• NA:
• upper plot should be in logscale
• when 'logscale' is enabled, frequency axis should be in log scale as well

[lneuhaus]

Scope gui: when in untriggered mode. Disabling "Channel2" or "Channel1" leads to strage behaviour:

• trace freezes instead of disappearing
• traces cease to the shown at all
  All depending on the order in which the Channels are (un-)selected..

====> Should be fixed now (871fcbd)

loading gui second time after it has been open without restarting session: infinite loop

[lneuhaus]

in untriggered mode: change time to one forbidden by untriggered mode: freezes

[lneuhaus]

when 2 guis (on 2 separate redpitayas) are open in the same kernel: very slow (more than 2x reduction) -> needs some automatic reduction of update rate to avoid deadlocks

[lneuhaus]

Gui open. User forgets to restart the kernel and loads redpitaya and gui a second time: Infinite competition between 2 guis leads to infinite timeout error

[lneuhaus]

last issue: can be avoided by catching socket.error in all timer-related functionality. We should make a function decorator for all functions that are called by a timer that kills the timer if socket.error happens.
