Gao has incorporated several fixes in the 1.6-esri branch (r19406) for the HDF5 driver which should likely be forward ported to trunk once understood.

It should be noted that some of these changes were backed out and others added in 1.6-esri (r19408).

and also r19409.

The majority of fixes have been incorporated in trunk (r19431) with this explanation:

Avoid setting bogus projection if we don't get georeferencing from CreateProjections?(). Avoid trying to operate if DeltaLat/Lon? is zero. Avoid crashing on NULL poH5Object->pszPath in CreateMetadata?().

I am still reviewing the parsing of the subdataset name. PRESERVESCAPES was used, but I suspect it was to avoid losing backslashes in the name when the proper approach would have been to escape them in the first place.

I have been unable to reproduce problems windows with backslash handling in tokenizing on windows and filenames - at least on windows - are not permitted to have embedded double quotes. Can you provide details on why the PRESERVEESCAPES change was needed?

The problem subdataset name is generated and returned from the driver itself when opening some HDF5 files.

Majority of fixes were incorporated 5 years ago with r19431. Some thinking was going on about PRESERVEESCAPES. Perhaps this ticket is still mature enough for closing.

Resolution: fixed

Closing as fixed because at least most issues in this ticket has been fixed. Better to create a new ticket about what remained if needed.
