| Summary | 0003493: Crash when moving regions in active edit group with hidden and inactive track | ||||
| Description | Steps to reproduce: * create a session * add two (or more) tracks * create an edit group and add both tracks to it * record equivalent regions onto both tracks * make the second track inactive and hide it * select a region in the first track and try to move it While you are moving the region, a 'phantom' region appears below it. then when you release the mouse to finish the move, Ardour crashes. | ||||

paul: I saw you assigned this to yourself when I first reported it - I presume to remind yourself to do something. It's still an issue in 2.0-ongoing, and also in 3.0-alpha. The actual crash in 2.0-ongoing is: Program received signal SIGSEGV, Segmentation fault. 0x082a4943 in Editor::region_drag_finished_callback(Gnome::Canvas::Item*, _GdkEvent*) () |

Actually, I spoke too soon: I can't reproduce this SIGSEGV, normally ardour just hangs. However, I've found that it's not necessary to de-activate the track: just hiding it is enough. |

The crash happens when trackview_by_y_position() returns NULL for hidden tracks in editor_mouse.cc (in 2.0-ongoing, anyway). Adding 'if (!tvp2)/if (!dest_tv) continue;' in the relevant places of editor_mouse.cc isn't a sufficient fix, however: weird things (disappearing regions, 'stuck' 'phantom' regions, etc.) still happen, though it does at least prevent the immediate crash. I suppose the more fundamental question is 'what /should/ happen to the region selection when a hidden track is part of an active edit group?'. I can see that dragging regions up and down tracks has the potential for some very confusing behaviour, though I'd like it if drags along the same track were to work on the hidden tracks too. |

Fixed in 3.0, SVN 10283. |

Almost perfect: thank you! One niggle: if I hide one track in an edit group, then move some grouped regions that include one on the hidden track, and then un-hide the track again, the region on the ex-hidden track doesn't reappear. It's still there, just invisible: if I then move one of the grouped regions on another track again, it magically springs back into view. [EDIT] this is with A3 now. |

The rest of this should be fixed in SVN 10571. |
