Entwine info freeze when missing tiles

[julienperrot]

Hello,

We observe in certain cases a blockage of entwine info when tile files are missing in the ept-data directory.

This blockage is not systematic for the same pyramid (approximately once every 3 or 4 times).
This blockage is reproduced on several different environments.
This blockage never seems to occur when the pyramid is complete.

The command executed is as follows:
entwine info --input "/path_to_ept.json" --verbose --deep --threads 8

verbose and threads have been modified without changing the behavior.
Entwine is version 3.1.0.

Thank you in advance.

While this may be a bug, I would first point out that entwine info is not intended to be used with EPT data, but rather to gather metadata information about unindexed source files before indexing into EPT. See the doc here: "The info command is used to aggregate information about unindexed point cloud data prior to building an Entwine Point Tile dataset". We try to support EPT as input in the rare case that you want to rebuild data from existing EPT datasets, but this is not generally a widely expected use-case.

For gathering information about an EPT dataset, you can use pdal info. Since pdal is a dependency of Entwine, you should have it available wherever you are currently trying to use entwine info. Note that PDAL's EPT reader also expects your EPT data to be fully readable, but you can use the option readers.ept.ignore_unreadable (doc) to skip nodes that cannot be read.
