dap code will create a real temporary file in which to store the
converted metadata for the DAP .dds or .dmr.
It was assumed that the nc_close code would reclaim the
temporary file. For DAP2, reclamation occurs in the ncio
code. For DAP4, it was assumed that the libsrc4 code would do
the reclamation, but for whatever reason, this is not happening.
Thus, in this situation, a temporary file is left in the file
system. Aside from being irritating to users, this screws up
'make distcheck'.
So the DAP4 code is fixed to ensure that the temporary file is
properly reclaimed independent of the libsrc4 code.
nc4_check_name() checks that the provided string doesn't exceed NC_MAX_NAME,
but fails to do so after calling nc_utf8_normalize(). This extra check is
needed since a caller of nc4_check_name(), like NC4_def_dim, allocates
norm_name as char norm_name[NC_MAX_NAME + 1]

2. modified ncdap_tests to remove <cr>
from generated output before comparison
to expected. This is a hack because
my other attempts to force windows to use
binary mode have not worked.
were added to provide a path name converter from e.g. cygwin
paths to e.g. windows paths. This is necessary because
the shell scripts may produce cygwin paths, but the code
may have been compiled with Visual Studio. Similar issues
arise with Mingw.
At appropriate places, and if using Visual Studio or Mingw,
I added calls to the path conversion code.
Apparently I forgot to find all the places where this
conversion was needed. So this pr does the following:
1. Push the calls to the converter to the various libXXX
directories and out of libdispatch/dfile.c.
2. Add conversion calls to other parts of the code like oc2.
I also turns out that conversion code in dapcvt.c
had a bug when handling DAP Byte type under visual studio.
Notes:
1. there may still be places I missed that need to do path conversion.
2. need to make sure that calls to e.g. H5open also use converted path.
Some temporary files are being left in a tempdir (e.g. /tmp
under *nix*).
The situation is described tersely in
netcdf-c/docs/auth.html#REDIR Basically, when a url is used that
requires redirection, a physical cookiejar file is required
to exist in the file system in order for this to work.
Since it was difficult to figure out when redirection was
being used (it was internal to libcurl) I needed to be prepared for that
eventuality. The result was that I always created a cookiejar file if one
was not specified in the rc file. This actually occurs in two places:
one inside oc2 and one inside libdap4.
The solution was two-fold:
1. do not use a cookiejar directory -- create cookiejar file directly
2. ensure that all cookiejar related files are reclaimed by nc_close().
Note that if nc_close (or nc_abort) is not called for whatever reason,
then reclamation will not occur.
The problem was that for opendap, it is possible to use keywords
as identifiers
when there is no ambiguity. However, the DAP2
parser lost the case of the identifier used the lower case version.
Fix is to use the actual text of the symbol when it is used as an identifier.
Also added a test case for this (kwcase.*).
Additionally cleaned up some misc. dap2 testing problems.
1. ncdap_test/tst_ncdap3.sh was using an empty test set.
restored the testing of datasets.
2. as a consequence of #1, some tests needed to be updated with minor
tweeks.
3. fix dapmerge to handle multiple DODS_EXTRAS attributes.
4. modify buildattribute to suppress nul characters and terminate
the name at the first nul.
5. clean up various test scripts to remove residual, unused
references to obsolete netcdf-4 translation.
6. export e.g. NCDUMP from test_common.in so that non-top-level
shell scripts can access it.
