A set of typecasts in the function
print_enum_type in ncdump/ncdump.c cause some
compilers to complain about type punning:
warning: dereferencing type-punned pointer will
break strict-aliasing rules
Fix is to cast to void* before casting to final
value. There may be other occurrences in some
of the older netcdf-c code.
to get TOPSRCDIR that avoids use of
TEST_ENVIRONMENT and makes automake and cmake
more consistent.
Basic assumption is that abs_top_srcdir (and
cmake equivalent) is known at 'make check' time,
so we can use -D flag to compile a program that
has the value of abs_top_srcdir embedded into it
as a constant.
We define two new files in ncdap_test:
1. t_srcdir.h -- provide a gettopsrcdir() function
to return the topsrcdir value to the test program.
2. topsrcdir.c -- a program that calls gettopsrcdir()
and prints its output (minus any newline) on stdout.
This is used in .sh files to get topsrcdir.
Modified provenance code to allocate the minimal space
needed for _NCProperties attribute in file. Basically
required using malloc in the provenance code and in ncdump.
Otherwise should cause no externally visible effects.
Also removed the ENABLE_FILEINFO from configure.ac since
the provenance code is no longer optional.
not being computed. Fix in nc4file.c.
Not sure how this ever worked for any variable.
What is also weird is that the dim hash is
apparently being computed.
re: github netcdf-c issue #271
This occurs for several reasons, including:
1. using H5Aopen_name instead of H5Aexists to test if attribute exists.
2. using H5Eset_auto instead of H5Eset_auto2.
There are probably others that will have to be extinguished as encountered.
p.s Hope I did not overdo this and kill too much.
Charlie Zender noted that we forgot to define what happens for
various netcdf API attribute operations, notably nc_inq_att()
and nc_get_att().
So, I added a list of legal and illegal api calls for the provenance
attributes in docs/attribute_conventions.md.
I also added more test cases to ncdump/tst_fileinfo.c to verify
and fixed resultant errors.
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.
If a char valued attribute contains embedded nul characters,
then illegal xml will be generated when using the -x (ncml) flag.
There is not good solution since we have a char value '\0' that
is legal in a netcdf-c char valued attribute, but is completely
illegal in ncml (i.e. xml).
So, implemented hack is to go ahead and generate '�' entities
and then complain that we are generating illegal ncml.
NetCDF-c Github issue #185
The code in libsrc/dim.c has not been upgraded to support
CDF-5 format.
Rule we are implementing sets the max dimension sizes as follows:
Classic: CDF-1 NC_MAX_INT - 3 = 2147483647 - 3
64 bit Offset: CDF-2 NC_MAX_UINT - 3 = 4294967295 - 3
64 bit Data: CDF-5 NC_MAX_UINT64 - 3 = 18446744073709551615 - 3
The -3 is to handle rounding.

The ncgen man pages says:
> Note also that the words variable',dimension', data',group', and
> `types' are legal CDL names, but be careful that there is a space be-
> tween them and any following colon character when used as a variable
> name. This is mostly an issue with attribute declarations.
Ncdump does not obey this rule.
The fix is to modify ncdump/ncdump.c to check if a variable name is
a keyword.
Also added test case.
that were not taking the CDF-5 format into account.
2. Had to update ncgen.1 man page to define the new
k-flag rules to deal with cdf-5.
3. Had to fix some tests that use 'cmp' for comparison;
this really should be deprecated.
3. There was a bug in configure.ac with respect
to using the enable-netcdf-4 flag vs
using disable-netcdf-4.

Ward's issue
If the netCDF-C library is built with the
HDF5 library but without the HDF4 library and one attempts
to open an HDF4 file, an abort occurs rather than returning
a proper error code (NC_ENOTNC).
Fix is to modify dfile.c#NC_check_file_type to properly
#ifdef relevant tests.
