| Summary | 0006898: ardour freezes during clean-up | ||||
| Description | KXStudio 14.04.2 LTS - Release amd64 Dear all, i have had a problem with Clean-up for a while: If i go to Session>Clean-up>Clean-up Unused Sources...>Clean-up nothing happens. The popup below does not appear http://robin.linuxaudio.org/tmp/cleanup.png Ardour freezes and if i try to close Ardour it takes a while and an "Ardour is not responding"screen pops up. I ran in gdb and that is here: http://pastebin.com/7zETEQGS If you tell me how i would attach my session file as well. I found out: if i try to uncombine the first compounds from Droomvlucht-solo(@ 07:13:21:08, tracks: "gitaar-room" and "gitaar" ) they are deleted. (i have the original session file(without -3001) too but it cannot be attached?, pressing browse nothing happens) nb: i hope i filled in everything correctly: any questions, just ask please :) | ||||

the issue persists in Ardour 5.12 |

I can reproduce the freezing issue with cleanup sources and the Session you have attached with 5.12 Based on the gdb backtrace you have referenced and the comment in SessionPlaylist::source_use_count () there may be circular references between compound regions and this is causing an infinite loop/freeze. Thanks for taking the time to report this and attaching a Session that can be used to reproduce the issue. |

I've attached a trace that can be loaded in chrome://tracing that shows the function calls occurring with this session when calling Session::cleanup(At least the first few seconds before I have to interrupt the process so as to not write too large a trace file). It indicates that the amount of deep nesting (8-9 levels at least) of compound regions in combination with the number of sources in this session may be causing the freezing as in the trace it is still processing the first source out of 0000109:0000400 after 4 seconds. I'm unsure that the freeze is actually infinite at this point and how there can be circular references. It does definitely indicate that another method of processing the sources to determine which ones can be "cleaned up" is perhaps needed. It seems like a method in which each snapshot is loaded and then determining unused sources based on the reference count of the source would much quicker, or possibly just something like storing the Source reference count in a property of the Source on save and using that instead. |

Hi, I want to add that freezing when trying to clean up still happens using Ardour 6.2. It always happens after a longer cut and paste session on for instance 5 recorded Vocals tracks or setting a bass drum track on time. After that I consolidate those tracks and then I want to clean up and then is when it all goes wrong. When it freezes while cleaning up (selecting clean up unused sources). The project still can be re-opened again but only increases in size. So after this happening the session gets useless. Exporting track is the only options and you loose all mixing, bussing, and track plugin settings. I did some research and found out it has nothing to do with which audio files are in the audio folder or even which tracks are in the project. Even after deleting all tracks in that pariticular project, is still freezes after clicking remove all unused sources. So it must be some corruption in the "projectname.ardour" file. I still have a spare copy of one of these crashed projects. If someone wants to examine it i can load it up. |

Refering to 0024848 (excusing for repeating this but the file won't load up) Is there a work around to recover from this project. Deleting all PEAK files didn't solve the problem either? Is the a way to prevent this happening. would it help if I clean up more frequently? |

Crashing when try to clean up unused sources Platform Windows 10 Ardour 6.9 Also, clean up of regions or writing to the session file may be involved? With simple projects, after I clean up regions, the number of <Region name=...> XML nodes matches the number of regions displayed in the Editor List. However, in one recent project that has a number of edits in it, the Editor List shows 24 regions after cleanup, but the session file has 2100+ <Region name=...> XML nodes. Maybe that is relevant. |
