Blender 2.8: workspace list from user configuration is empty
Closed, ResolvedPublic


Short description of error
List of workspaces in user configuration sometimes is empty. Should never be the case.
If no workspaces.blend is found in the user configuration itself (which must never have 0 workspaces), the bundled default one is used as fallback (should be in [build_dir]/[release_dir]/datafiles/).
The user who reported this did have the bundled workspace.blend in the right place, so this is not the cause.

Exact steps for others to reproduce the error

  • Launch Blender from command line
  • Press "+" button to add a new workspace
  • If appearing menu only contains "Duplicate Current", there's the bug.

Mainly leaving this here for myself.

Got it! Happens all the time when launching Blender from command line here. Still need to investigate but now I know how to recreate at least :)

So this only happens for dev builds executed from the build directory. It's caused by this loading a different release directory path for dev builds;33b5e8daff2cfe269bdb527cf0de6dd083b01daf$323-331.

I'd suggest this fix

The ugly thing is it actually copies the default workspaces.blend to two directories:

  • Once during CMake configuration. Copied into [build_dir]/release/datafiles.
  • Once during make install. Copied into [install_dir]/[version]/datafiles.

That said it should work fine with all cases.

Alternatively we could remove mentioned lines in appdir.c, although I don't know what it's currently used for. @Campbell Barton (campbellbarton)/@Sergey Sharybin (sergey) any opinion on that matter?

I think it's simplest to do datatoc as startup.blend unless there is a good reason to make this work differently.

AFAICS no big changes are needed for this, just follow existing conventions.

Update, swapping CWD & EXE dirs is far simpler!
