Primary change is to cleanup code and remove duplicated code.
1. Unify the rc file reading into libdispatch/drc.c. Eventually extend
if we need rc file for netcdf itself as opposed to the dap code.
2. Unify the extraction from the rc file of DAP authorization info.
3. Misc. other small unifications: make temp file, read file.
4. Avoid use of libcurl when reading file:// because
there is some kind of problem with the Visual Studio version.
Might be related to the winpath problem.
In any case, do direct read instead.
5. Add new error code NC_ERCFILE for errors in reading RC file.
6. Complete documentation cleanup as indicated in this comment
https://github.com/Unidata/netcdf-c/pull/472#issuecomment-325926426
7. Convert some occurrences of #ifdef _WIN32 to #ifdef _MSC_VER
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.
1. Cleanup test_common.sh to expunge (mostly) the use of the VS
path value. This has the effect of being unable to use the
Visual Studio C compiler for shell tests.
2. There is a missing case in CMakeLists.txt so add
defaulting for HDF5_C_LIBRARY_hdf5 using HDF5_C_LIBRARY.
Ward should probably examine this to get it fixed correctly.
3. Put back ref to esg.md in docs/Doxyfile.in
4. Fix minor warning in dut8proc.h
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
re: https://github.com/Unidata/netcdf-c/issues/365
1. Added to RELEASENOTES.md
2. Add a range check to more closely
mimic unix sscanf
3. locate and fix same sscanf problems in ncgen/cvt.c
Still need a stable url for a test case.
Following command fails under visual studio.
ncdump -h http://thredds.ucar.edu/thredds/dodsC/nexrad/composite/gini/n0r/1km/20170216/Level3_Composite_n0r_1km_20170216_1635.gini
The problem is that sscanf for windows does not appear to support
scanning 8bit integers: it appears to only allow scanning of characters.
Solution:
Scan the input as an integer (for type Byte) or unsigned int (for type UByte)
and then recast the result as a char or unsigned char.
Primary code fix is in libdap2/dapcvt.c#dapcvtattrval
to get TOPSRCDIR that avoids use of
TEST_ENVIRONMENT and makes automake and cmake
more consistent.
Basic assumption is that abs_top_srcdir (and
cmake equivalent) is known at 'make check' time,
so we can use -D flag to compile a program that
has the value of abs_top_srcdir embedded into it
as a constant.
We define two new files in ncdap_test:
1. t_srcdir.h -- provide a gettopsrcdir() function
to return the topsrcdir value to the test program.
2. topsrcdir.c -- a program that calls gettopsrcdir()
and prints its output (minus any newline) on stdout.
This is used in .sh files to get topsrcdir.
This consists of a persistent attribute named
_NCProperties plus two computed attributes
_IsNetcdf4 and _SuperblockVersion.
See the 'Provenance Attributes' section
of docs/attribute_conventions.md for details.
User request to have all orphaned DAP2 attributes kept as netcdf
global attributes. This is primarily a change in the oc code
nplus testcase dataset changes.
Result may be inconsistent with netcdf-Java output.
AC_CHECK_SIZEOF is not working because anti-virus
will not allow very rapid creation/deletion of a
file with same name.
2. modified some test baselines to attempt to fix
Ward's issue
The code for handling character constants
in datalists in ncgen has some problems.
1. It failed on large constants
2. It did not handle e.g. var = 'a', 'b', ...
in the same way that ncgen3 did.
3. The code for generate.c and genchar.c needed
some refactoring to make it a little simpler
(but not simple).
