Test failures when downloading Blender #672

Closed emackey closed 5 years ago

emackey commented 5 years ago

Recent tests have all failed when trying to download Blender.

/cc @pjoe Any ideas?

Looks like Blender 2.79 download step now times out and fails after 10m.

Will try taking a closer look tomorrow.

Btw. also noticed we are no longer testing against 2.80 but 2.81 - just wondering if that is on purpose?

Yes. There have been API changes between 2.80 and 2.81. Also more generally, we're preparing to ship the newest version of this addon with the 2.81 release, so it must be tested against that. The 2.80 release has already sailed, and bundles an older stable version of this addon that was tested with it at the time.

We're holding onto 2.79 support for now, but someday that will be gone too.

So for now, the two test targets are 2.79 and 2.81. The 2.81 will likely change to 2.82 after the release later this month.

I did a PR #673 to change the timeout to 20 min :S

Obviously not ideal solution - IIRC the blender devs mentioned that download.blender.org doesn't have CDN while builder.blender.org has (which is why this is only an issue for 2.79).

Thanks @pjoe for fixing the download timeout.

There was another odd error, an unhandled promise rejection, which I've fixed in the test suite in commit 842e4b04b130.

The remaining test failures appear to be very serious: The Blender 2.81 build isn't exporting any texturemaps from several of the round-trip test models. Specifically, all of the numbered entries in this list have failed to export textures:

  Importer / Exporter (Roundtrip)

      2) 01_alpha_mask

      √ 03_skinned_cylinder (955ms)

      8) 04_lenna
      √ 04_lights (830ms)
      √ 04_sphere_specular_glossiness (939ms)
      √ 05_metallic_sphere_light (961ms)
      √ 05_node_material (1110ms)
      √ 06_parent-inverse-anim (880ms)
      √ 07_nla-anim (840ms)

      10) 09_texture_transform
      √ 10_custom_normals (860ms)
      √ Box (850ms)

I'm still investigating why. Blender 2.79 and 2.80 are able to round-trip these models without any problem.

Closing this, discussion will continue in #674.
