As it was, nccopy -c dim/x was sometimes being ignored. So
modify nccopy to properly take into account. This also required
a change to the nczarr code because it was not applying default
chunking in the same way as libhdf5.
Modify ncdump/tst_nccopy4.sh to test this feature properly.
Also add a similar test to nczarr_test.
Additionally, fix some other things that were causing Visual
Studio builds with testing to not work.
* fix curl testing under CMake to properly handle case
where DAP is disabled, but byterange support is enabled.
* properly test and/or define uintptr_t
* Convert _O_XXX to O_XXX flags used by open();
disengagement of enable-netcdf4 from enable-hdf5.
That is, with the advent of nczarr, it is possible
to turn off hdf5 but still need netcdf-4 enabled
because nczarr uses libsrc4, but not libhdf5.
This change involves a bunch of things:
1. Modify configure.ac and CMakelist to make enable_hdf5
control if hdf5 support is provided. For back compatibility,
disable-netcdf4 is treated as disable-hdf5. But internally,
netcdf4 support is controlled only by the enabling of formats
that require it.
2. In support of #1, modify .travis.yml to use enable/disable-hdf5
instead of enable/disable-netcdf4.
3. test_common.in is modified to track selected features,
including enable-hdf5 and enable-s3-tests. This is used in
selected tests that mix netcdf-3 and netcdf4 tests.
4. The conflation of USE_HDF5 and USE_NETCDF4 is common in
code, tests, and build files, so all of those had to be weeded out.
5. It turns out that some of the NC4_dim functions really are HDF5 specific,
but are not treated as such. So they are moved from nc4dim.c to
hdf5dim.c or hdf5dispatch.c
6. Some generic functions in libhdf5 can be (and were) moved to libsrc4.
re: issue https://github.com/Unidata/netcdf-c/issues/1233
Changes:
1. remove exit that was there for testing.
2. the program tst_open_mem must be netcdf-4 only.
3. fix some diff problems
- Change dataset name for tst_inmemory4_create to tst_inmemory4
- Modify tst_inmemory.c to reorder the variables (somewhat major rewrite)
Minor Unrelated Fixes:
1. fix comment problem in nc_provenance.h
2. Fix memory leak in tst_open_mem.c
3. fix ncdump/bindata.c to properly compile if netcdf4 is disabled.
4. minor changes to ncgen.l
re: github issue https://github.com/Unidata/netcdf-fortran/issues/82
This was originally discovered in the Fortran tests, but is
a problem in the C library.
The problem only occurred when using HDF5-1.10.x. The reason it
failed is that starting with 1.10, the hid_t type was changed
from 32 bits to 64 bits.
The function libsrc4/nc4memcb.c#NC4_image_init was using type int (doh!)
to return the hdf fileid instead of hid_t type. This, of course,
caused the id to be truncated and in turn later use of the id
caused hdf5 to fail.
Fix is trivial: replace int with hid_t. This also requires a related
change in nc4mem.c.
Also added the test case derived from the original Fortran code.
You would think I would learn...
