Hi,

I am having trouble with closing hdf5 file handles. The issue can be reproduced with a small code chunk below:

library(rhdf5)
file.name <- tempfile()
h5createFile(file.name)
fid <- H5Fopen(file.name)
H5Fclose(fid)
h5validObjects()

With rhdf5 v 2.16.0 the result is (as expected):

list()

but with v 2.18.0 I get:

[[1]]

HDF5 GENPROP_LST

Opening/closing each new hdf5 file leaves additional GENPROP_LST object behind. Does anyone know what does GENPROP_LST object represent and how to close it selectively w/o using H5close()?

This has hopefully been fixed in rhdf5 version 2.21.3

A change was made between version 2.16.0 and 2.18.0 so that when H5Fcreate() was called a list of properties to be used during the file creation was generated. This list was never subsequently closed, hence why you would see these hanging around.
