A user suggested that the nccopy -F option
syntax should be extended to support specification
of multiple (or all) variables in a single -F option.
The new syntax allows:
1. '*' as the name of the variable; this means apply the
filter to all variables in the data set.
2. *var1|var2|...* as the variable name to indicate that the filter
should be applied to the multiple specified variables.
Primary fixes to get -ansi to work.
1. Convert all '//' C++ style comments to /*...*/ or to use #if 0...#endif
2. It turns out that when -ansi is specified, then a number of
functions no longer are defined in the header -- but they are still
in the .so file.<br>
The big example is strdup(). So, added code to include/ncconfig.h to define
externs for those missing functions that occur in more than one place.
These are enabled if !_WIN32 && __STDC__ == 1 (__STDC__ is supposed to
be the equivalent compile time flag to -ansi). Note that this requires
config.h (which references ncconfig.h) to be included in files where it is
currently not included. Single uses will be only in the file that uses them.
3. Added mmap test for the MAP_ANONYMOUS flag to configure.ac. Apparently
this is not always defined with -ansi.
4. fix some large integer constants in nc_test4/tst_atts3.c and nc_test4/tst_filterparser.c
to avoid compiler complaints.
5. fix a double constant in nc_test4/tst_filterparser.c to avoid compiler complaints.
[Note I suspect #4 and #5 will be a problem on big-endian machines, but we have no way to test]
Misc. Changes:
1. convert more instances of _MSC_VER to _WIN32.
2. added some debugging code to include/nctestserver.h
3. added comment about libdispatch/drc.c always being compiled.
4. modify parser generation in ncgen to remove unneeded files.
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
https://github.com/Unidata/netcdf-c/issues/1168https://github.com/Unidata/netcdf-c/issues/1163https://github.com/Unidata/netcdf-c/issues/1162
This PR partially fixes memory leaks in the netcdf-c library,
in the ncdump utility, and in some test cases.
The netcdf-c library now runs memory clean with the assumption
that the --disable-utilities option is used. The primary remaining
problem is ncgen. Once that is fixed, I believe the netcdf-c library
will run memory clean with no limitations.
Notes
-----------
1. Memory checking was performed using gcc -fsanitize=address.
Valgrind-based testing has yet to be performed.
2. The pnetcdf, hdf4, and examples code has not been tested.
Misc. Non-leak changes
1. Make tst_diskless2 only run when netcdf4 is enabled (issue 1162)
2. Fix CmakeLists.txt to turn off logging if ENABLE_NETCDF_4 is OFF
3. Isolated all my debug scripts into a single top-level directory
called debug
4. Fix some USE_NETCDF4 dependencies in nc_test and nc_test4 Makefile.am
