OpenFileGDB: add partial read-only support for tables with 64-bit ObjectIDs

Open rouault opened this issue 1 year ago • 0 comments

Tables with non-sparse pages in .gdbtablx are fully supported.

A subset of tables with sparse pages are properly supported (cf https://github.com/rouault/dump_gdbtable/wiki/FGDB-Spec#trailing-section-16-bytes--variable-number-) When we detect that we can't properly decode ObjectID in the unsupported subset of sparse tables, we emit a warning, and turn off use of attribute/spatial indices.

Read-only support for now.
