Comment 1 Peter Sampson 2018-03-04 07:08:43 UTC

This command has previously been hidden bt Bug #1839 which has recently been fixed.

If the user has a selection which is at the end of the audio or beyond it and the sets up a Timer Record for a period longer than the selection length then The recording will stop at the end of the selection

This is normal expected behavior in normal attended recording - but given that Timer Recording is mainly designed for unattended recording this bug exposes the user to potential data loss (quite possibly of an unrepeatable event).  For a TR I am firmly of the view that the user's settings in the TR should over-ride any selection lenththa may be present.

Because of the potential for data loss I am giving this a P2 rating.

I'll take this.

(In reply to Steve Daulton from comment #3)
Tested on W10 Audacity 2-3-0 20180305-76
and on macOS 10.13.3 High Sierra  audacity-macos-nightly-2.3.0-ea0e0d7.dmg 

The Timer Record settings are honored properly on both platforms (this is achieved by cancelling the selection)
