The pnetcdf support was not
properly being used to provide
mpi parallel io for netcdf-3 classic
files. The wrong dispatch table was being
used. The fix was to modify
dfile.c#NC_check_file_type to properly
specify the pnetcdf dispatch table when
use_parallel was true.
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.
was incomplete; complete the fix.
2. There is an inconsistency in the netcdfh interface
about whether rank (# dimensions) is an int or
size_t. I inadvertently assumed the latter and that
breaks some API calls; so revert back.
times, but returning the same ncid.
2. Separate out the dap auth tests
and make them disabled by default.
3. turn of ncdap_test/test_varm3 until
we can find a copy of coads_climatology.nc
Add a new function called nc_inq_format_extended that
returns more detailed format information (vis-a-vis
nc_inq_format) about an open dataset.
Note that the netcdf API will present the file as if it had
the format specified by nc_inq_format. The true file
format, however, may not even be a netcdf file; it might be
DAP, HDF4, or PNETCDF, for example. This function returns
that true file type. It also returns the effective mode for
the file.
signature: nc_inq_format_extended(int ncid, int* formatp, int* modep)
where
* ncid is the NetCDF ID from a previous call to nc_open() or
nc_create().
* formatp is a pointer to a location for returned true format.
* modep is a pointer to a location for returned mode flags.

Also added test cases (tst_formatx*).
unlimited dimension hanging. Extending the size of an unlimited
dimension in HDF5 must be a collective operation, so now an error is
returned if trying to extend in independent access mode.
Quincey's bug fixes for parallel build portability, particularly
OpenMPI on MacOS-X.
Problem was that the NC_create
code was not checking for the NC_CLASSIC_MODEL
mode flag in deciding what dispatch table to use.
This meant that it was then defaulting to use
the default format, and if that was changed
to e.g. NC_FORMAT_NETCDF4, then it would try
to create a netcdf-4 format file, even is
NC_CLASSIC_MODEL mode flag was set.
for JIRA issue NCF-241.
This is only temporary
until I can make pnetcdf
operate as a separate dispatch table.
Also, fix nc_test4/tst_pnetcdf
to open with nc_open_par;
this is necessary because a pnetcdf
created file cannot be opened
as a netcdf classic file.
read 4 bytes from a 3 byte file, Windows would fail with an
error 22, "Invalid Operation". This would happen when trying to
read the 4-byte magic number from a very small file.
This problem was uncovered by nc_test/tst_misc.c.
When fread returns 0 and errno is 22, NC_ENOTNC is returned.
contain as little file-type specific info as possible. It
modifies especially libsrc so that all of the netcdf-3 data
that used to be in struct NC is now kept in a separate chunk
of data pointed to by the struct NC. This makes all of
current protocols consistent: netcdf-3, netcdf-4, and dap.
The in-memory files can be made persistent if nc_create is called with
NC_DISKLESS|NC_WRITE flags set. Initial test case also included.
- Modified ncio mechanism to support
multiple ncio packages; this is so we
can have posixio and memio operating
at the same time.
- cleanup up a bunch of lint issues (unused variables, etc).
- Fix NCF-157 to modify DAP code to support
partial variable retrieval.
- Fix of NCF-154 to solve problem of ncgen
improperly processing data lists for variables
of size greater than 2**18 bytes.
- Fix ncgen processing of char variables that have
multiple unlimited dimensions.
- Partly fix Jira issue: NCF-145 (vlen issues).
- Benchmark program nc_test4/tst_ar4_*) requires arguments
and should only be invoked inside a shell
script; fixed so that they terminate cleanly
if invoked with no arguments.
- Fix the Doxygen processing so it will work
with make distcheck.
- Begin switchover to using an alternative to ncio.
- Begin support for in-memory (diskless) files.
