Attempts simply crash the application. * This has been only been observed in Ubuntu 20.04 LTS. Attempts to reproduce the behavior on 18.04, 19.10, and Groovy Gorilla proved fruitless. * Upon investigation, the bug was a regression in lilv 0.24.6 which was corrected in 0.24.8 per https://github.com/lv2/lilv/issues/32 and its attached commit. [Test Case] * In Ardour, start a new project, go to the Mixer view. * Add a track to the project * Add any LV2 plugin to the track * Open the LV2 plugin interface via a double-click on the plugin * Save a "New" preset, use any name. * Make a change to the plugin state (any parameter), click "Save". Ardour will crash. [Regression Potential] * This library (lilv) affects LV2 plugins and only LV2 plugins. Version 0.24.8 contains a number of bugfixes to enhance the stability of LV2 plugins, including the bugfix mentioned. * Even though this version contains a number of bug fixes, there is always potential for some regression in LV2 plugins to occur, such as misbehavior or other regressions similar to this particular bug. [Other Info] * The diff in this case is quite large due to the number of bugs fixed. While it is possible for a simple cherry pick of the commit in question, I believe there is an even greater risk of regression or bugs appearing if the full bugfix release is not used. * The full bugfix release (0.24.8) fixes many bugs and does not contain any new features as far as I can tell. Original bug follows: The few lv2 plugins I have tried all crash ardour when I click on "save" to save the preset. Clicking Add to create a new plugin doesn't crash, but it also does not save the preset. If you load a plugin preset already created and then click save, you end up wiping out the contents of the preset direcoty in ~/.lv2. The .ttl files are deleted and you end up with an empty directoy. The only thing printed on the console when this happens is this: CALF DEBUG: instance 0x55c00d102860 data 0x55c01ca1cf10 CALF DEBUG: calf 0x7f8d31f7b0f0 cpi 0x7f8d31783ca0 Segmentation fault (core dumped) AFAIK, teh preset add and save functions work for ladspa plugins. -Don ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: ardour 1:5.12.0-3ubuntu4 ProcVersionSignature: Ubuntu 5.4.0-29.33-lowlatency 5.4.30 Uname: Linux 5.4.0-29-lowlatency x86_64 ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: XFCE Date: Sat May 9 21:39:09 2020 InstallationDate: Installed on 2020-04-26 (13 days ago) InstallationMedia: Ubuntu-Studio 20.04 LTS "Focal Fossa" - Release amd64 (20200423) SourcePackage: ardour UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ardour/+bug/1877806/+subscriptions -- Mailing list: https://launchpad.net/~ubuntustudio-bugs Post to : ubuntustudio-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntustudio-bugs More help : https://help.launchpad.net/ListHelp
