re: esupport 31942
* Add a new set of remote tests based on using the opendap hyrax server
* Re-enable --enable-dap-remote-tests as default on
* Make it possible to query the DMR separate from the DAP
so that it is possible to delay reading data until it is actually
requested. This make things like ncdump -h much more efficient.
* Fix handling of <Map>s in DMRs.
* Fix some memory leaks
re: https://github.com/Unidata/netcdf-c/issues/1451
The situation with the various DAP (and other) remote test
servers is currently in a state of flux. For example, Unidata
admin is planning to forcibly shift the remote test server to
remotetest.unidata.ucar.edu soon. In addition, the server
test.opendap.org has shown some recent instability.
The result is that various DAP (and byterange) tests can fail
unexpectedly. This is an irritant to users and reveals nothing
about test sucess or failure.
Solve by modifying tests to report server inaccessibility and
otherwise pretend to succeed.
This puts an onus on Unidata to detect such server failures, but
will not cause users to see spurious failures. [Note. Do similar
fix for netcdf-java]. The check is:
1. export SETX=1 to cause all the shell scripts to trace
2. search the log files for the phrase "WARNING" (in upper case)
and see if it is complaining about not finding a server.
Misc. Changes
-------------
1. Added a pingurl program to see if a server was up.
2. modified some test case url targets
re: issue https://github.com/Unidata/netcdf-c/issues/1151
Modify DAP2 and DAP4 code to handle case when _FillValue type is not
same as the parent variable type.
Specifically:
1. Define a parameter [fillmismatch] to allow this mismatch;
default is to disallow.
2. If allowed, forcibly change the type of the _FillValue to match
the parent variable.
3. If allowed Convert the values to match new type
4. Generate a log message
5. if not allowed, then fail
Implementing this required some changes to ncdap_test/dapcvt.c
Also added test cases.
Minor Unrelated Changes:
1. There were a number of warnings about e.g.
assigning a const char* to a char*. Fix these
2. In nccopy.1, replace .NP with .IP "n"
(re PR https://github.com/Unidata/netcdf-c/pull/1144)
3. fix minor error in ncdump/ocprint
So it now becomes the first default test server to try.
This also means that the dap4 remote testing is enabled.
The only issue to watch is to see if the jetstream-based
server can stay up for significant periods of time.
A uptimerobot (https://uptimerobot.com) has been set ups
to monitor this hourly, so we shall see.
1. When running under windows (as opposed to cygwin)
we need to make sure to not user /cygdrive/ file paths.
This was ocurring in libdap4/d4read.c, but may occur
elsewhere.
2. Shell scripts in the git repo are not being checked-out
with the executable mode set. Had core.filemode set to false.
Was a major hassle to fix.
Specific changes:
1. Add dap4 code: libdap4 and dap4_test.
Note that until the d4ts server problem is solved, dap4 is turned off.
2. Modify various files to support dap4 flags:
configure.ac, Makefile.am, CMakeLists.txt, etc.
3. Add nc_test/test_common.sh. This centralizes
the handling of the locations of various
things in the build tree: e.g. where is
ncgen.exe located. See nc_test/test_common.sh
for details.
4. Modify .sh files to use test_common.sh
5. Obsolete separate oc2 by moving it to be part of
netcdf-c. This means replacing code with netcdf-c
equivalents.
5. Add --with-testserver to configure.ac to allow
override of the servers to be used for --enable-dap-remote-tests.
6. There were multiple versions of nctypealignment code. Try to
centralize in libdispatch/doffset.c and include/ncoffsets.h
7. Add a unit test for the ncuri code because of its complexity.
8. Move the findserver code out of libdispatch and into
a separate, self contained program in ncdap_test and dap4_test.
9. Move the dispatch header files (nc{3,4}dispatch.h) to
.../include because they are now shared by modules.
10. Revamp the handling of TOPSRCDIR and TOPBUILDDIR for shell scripts.
11. Make use of MREMAP if available
12. Misc. minor changes e.g.
- #include <config.h> -> #include "config.h"
- Add some no-install headers to /include
- extern -> EXTERNL and vice versa as needed
- misc header cleanup
- clean up checking for misc. unix vs microsoft functions
13. Change copyright decls in some files to point to LICENSE file.
14. Add notes to RELEASENOTES.md
