11a259ad86 Add provenance info for netcdf-4 files. 
This consists of a persistent attribute named
_NCProperties plus two computed attributes
_IsNetcdf4 and _SuperblockVersion.
See the 'Provenance Attributes' section
of docs/attribute_conventions.md for details.

6409b11640 Modified nc_inq_type so that it will return valid information for valid data types even if the associated ncid doesn't have access to those data types. See https://github.com/Unidata/netcdf-c/issues/240 for more information. 2016-04-05 20:13:42 +00:00

1f9eb8093c Fix duplicate key issues in nc_hashmap 
The addition of the nc_hashmap to facilitate quick
retrieval of var and dim by name did not take into
account key collisions -- two or more names hashed
to the same value.  If the keys matched, it assumed
that the names matched also.

This change fixes this incorrect assumption and
checks both the key (which is the hash of the name)
and if the keys match, it also checks that the names
match.

While there have been no instances of duplicate keys,
they are certain to occur and cause difficult to
debug issues. This fix eliminates that defect.

1a84a6a99e Add hash field to dim and var to facilitate fast name compare 
In non-classic netcdf-4 models, it is allowable to have
large numbers of dims and vars.  In many operations, the
entire list of dims or vars is searched for a dim/var matching
a specific name which results in *lots* of strncmp or strcmp
calls.

If we add a hash field to the var and dim structs similar to what
has already been done for the netcdf-3 formats, then we can hash the
name being searched for and numerically compare that value with
the var/dim hash value.  If they match, then do a more expensive
strncmp call to ensure that the names truly match.

2d3278c58b Update comment 
If pnetcdf support is enabled, then  NC_HAS_PARALLEL is defined to 1 even if HDF5 is not enabled.  Fix comment to make this clearer.
