tarsupervoxels bugs #272

Closed stuarteberg closed 6 years ago

stuarteberg commented 6 years ago

I've observed the following issues with the hot-off-the-presses tarsupervoxels endpoint:

  1. When I create a tarsupervoxels instance while using the basholeveldb backend, I can post and read data. But using the filestore backend, no data is actually stored. Attempting to retrieve a key results in an error, such as:

    Error in retrieving supervoxel 14634755: open /magnetic/dvid-filestore/40/f8/b130/v84-i437-8501034fdf0000000000: no such file or directory (/api/node/3c0954d5534f4880a840ee937016ca73/labels_sv_meshes/supervoxel/14634755).

    Indeed, though the appropriate directory was created (.../dvid-filestore/40/f8/b130), it contains no files.

  2. When using the basholeveldb backend, I can store data and retrieve it using the /supervoxel endpoint. However, there are two minor problems with the /tarfile endpoint:

    • The files have extension .dat instead of the extension I stored them with (e.g. .obj or .drc)
    • The files have the wrong file permissions, as if someone used chmod 000 to set the permissions. That is, I can't even read the file until I change the permissions.

First issue should be resolved by commit 4e08e. Will look into second.
