H5Part development and discussion

[Mark Howison <MHowison AT lbl.gov>]

Hi Achim,

I've been debugging my H5Part regression tests and I've been getting
sporadic segfaults during file close that trace through
h5_close_mesh() to the h5priv_free() calls. My guess is that some of
the pointers in the H5Fed file data are not being initialized but are
also not NULL, so the "if(ptr) free(ptr)" logic in h5priv_free isn't
working. I'm going to try setting all those pointers to NULL initially
in one of the file open calls.

Another problem I've run into is that an h5_write_mesh call always
gets executed at file close regardless of whether the file is opened
for writing or reading. If the file is read only, this sets off a
CHECK_WRITABLE_MODE error. Can that write be moved?

Thanks
Mark
