Ardour crash on existing preset save in TAL-Noisemaker #15

Open Fak3 opened 8 years ago

Fak3 commented 8 years ago

To reproduce: 1) add TAL-Noisemaker to track, open its ui 2) in the Ardour preset selector select any "built-in" preset (of those from presets.ttl) 3) click "save" (the button to save preset, right of the preset selector) Ardour crashes with error "glibmm-ERROR ...unhandled exception... what: basic_string::_S_construct null not valid " After the crash "presets.ttl" file is gone, and there are no presets available in the ui anymore.

Expected behavior: preset with the same name should get saved into "~/.lv2/NoizeMak3r.lv2/" directory.

Bug only occurs if selected preset exist only in the "built-in" set of presets, meaning that it was not ever saved in dir "~/.lv2/NoizeMak3r.lv2/". Currently it does not get saved there, because of this bug.

Console log after i click "save":

Trying to overcome "Duplicate plugin" console error, i merged the contents of "TAL-NoiseMaker.ttl" into "manifest.ttl", and the preset get properly saved in the "~/.lv2/NoizeMak3r.lv2/" dir. But the "presets.ttl" file still gets deleted, and the same console error still pops-up: 

lilv_world_add_plugin(): error: Duplicate plugin <http://kunz.corrupt.ch/products/tal-noisemaker>
lilv_world_add_plugin(): error: ... found in file:///home/u1/.lv2/TAL-NoiseMaker.lv2/
lilv_world_add_plugin(): error: ... and      file:///home/u1/.lv2/TAL-NoiseMaker.lv2/

Seems like an ardour bug to me. Seems it's overriding the actual plugin bundle with preset data. I remember seeing an ardour commit related to this btw, where the user should not be able to edit factory presets.

Was this recent commit in Ardour? I am testing on 4.4

This one https://github.com/Ardour/ardour/commit/4be4f8fb6223394761496173fecaeb09b85eeb6c

Fak3 commented 8 years ago

Ok, i will test recent "nightly" Ardour

x42 commented 8 years ago

https://github.com/Ardour/ardour/commit/4be4f8fb6223394761496173fecaeb09b85eeb6c is only relevant for the new sidebar.

Fak3 commented 8 years ago

I checked current nightly Ardour (Ardour/ardour@027ffb1b371e94183e21700dae7e09dc07b4c7ac), and the bug is still there. @x42: What is this new sidebar? Is it available for testing, or still actively hacked on?

x42 commented 8 years ago

The issue is deeper. You should not be allowed to delete factory presets. it's not an ardour-bug per se. it's in liblilv (Lv2 library).. still investigating. meanwhile: just don't delete or replace factory presets :)

re sidebar. left side of the mixer, at the top "favorite" plugins are shown and can be dragged/dropped to/from channels.. more in the 4.5 release announcement, soon or on #ardour IRC.
