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. 2016-05-04 11:17:06 +08:00			`#define NC_ATT_NETCDF4 "_NetCDF4"`
Finalize the compression support. This relies on the HDF5 capability to dynamically load compression filters. Note that a compression filter is just a subcase of filters. The primary user-visible changes are as follows: 1. Add a standard header "netcdf_filter.h" that defines the necessary API extensions 2. Modify ncgen to support two new special attributes "_Filter_ID" and "_Filter_Parameters" so that compression can be turned on when creating a file using ncgen. 4. Add a detailed description of filtering support to the user's guide; see the file filters.md 5. Add a test case directory for this: nc_test4/filter_test. It is fragile and a ./configure flags (-enable-filter-test) is defined (default disabled) to shut this off this test to avoid spurious 'make check' failures. Note that the HDF5 documentation is not up-to-date, so much of what is encoded here comes from examining the actual code in the file H5PL.c in the HDF5 source code. 2017-04-28 03:01:59 +08:00			`#define NC_ATT_FILTERID "_Filter_ID"`
