[Bug 1969798] Re: Carla can't find plugins in plugin directories located in the user's home

 

** Description changed:

  [Impact]
  
  Users of Carla are unable to refresh audio plugins when more are
  installed, i.e. in the user's home directory. Furthermore, this can
  cause Carla to crash.
  
  [Test Plan]
  
-  * Launch Carla
-  * Click "Add Plugin"
-  * Click "Refresh"
-  * Click "Scan"
-  
-  Expected: Carla will scan for new plugins and find them.
+  * Launch Carla
+  * Click "Add Plugin"
+  * Click "Refresh"
+  * Click "Scan"
  
-  Actual: Carla does not scan for plugins, and may crash.
+  Expected: Carla will scan for new plugins and find them.
+ 
+  Actual: Carla does not scan for plugins, and may crash.
  
  [Where problems could occur]
  
-  * The patch may just plain not work, in which case we may have to do a
- wholesale upload of Carla 2.4.3 instead as opposed to simply patching
- 2.4.2 with the cherry-picked commit as uploaded.
- 
-  * The other thing this might do is cause the application to cease to
- function, though this is highly unlikely.
+  * This may simply cause a regression in Carla in which save files may
+ cease to load or other issues with plugins loading, however this is
+ highly unlikely.
  
  [Other Info]
-  
+ 
+ Originally the plan for this SRU was to upload a patched version of
+ Carla 2.4.2 which did not work as planned. 2.4.3 FTBFS when uploaded to
+ Kinetic, as did 2.4.4 when uploaded to a PPA built against Kinetic.
+ Eventually, it was proven that 2.4.4 would build cleanly in Jammy and
+ introduces essential bugfixes, including this fix as well as fixes
+ Python 3.10 compatibility issues that were merely patched before.
+ 
+ It is to be noted that this upstream version does *NOT* introduce any
+ new features, and the upstream developer was aware that any fixes he
+ made in this release could not introduce new features and could only
+ introduce bugfixes. As stated from the changelog, these bugfixes,
+ including the one in this SRU, include:
+ 
+  * Fix inaccurate MIDI CC rounding
+  * Fix python3.10 compatibility issues 
+  * Fix integration with internal Qt toolbar visibility state
+ 
+ These are essential fixes in functionality.

  Original bug report as follows:
  ------
  
  In the LV2 location in my home directory .lv2 I have the following
  plugin:
  
  ➜ ls ~/.lv2
  librnnoise_lv2.so
  
  ${HOME}/.lv2 is configured in Carla as a search path.
  
  In the Add Plugin dialog for Carla if I search for noise nothing shows
  up.
  
  This worked fine previously on 21.10.
  
  Release notes for Carla 2.4.3 [1] include this line: Fix plugin search
  (regression from 2.4.2)
  
  Ubuntu Studio 22.04 currently has the bugged version:
  
  ➜ carla --version
  Using Carla version 2.4.2
