re e-support UBS-599337 re pull request https://github.com/Unidata/netcdf-c/pull/405 re pull request https://github.com/Unidata/netcdf-c/pull/446 Notes: 1. This branch is a cleanup of the magic.dmh branch. 2. magic.dmh was originally merged, but caused problems with parallel IO. It was re-issued as pull request https://github.com/Unidata/netcdf-c/pull/446. 3. This branch + pull request replace any previous pull requests and magic.dmh branch. Given an otherwise valid netCDF file that has a corrupted header, the netcdf library currently crashes. Instead, it should return NC_ENOTNC. Additionally, the NC_check_file_type code does not do the forward search required by hdf5 files. It currently only looks at file position 0 instead of 512, 1024, 2048,... Also, it turns out that the HDF4 magic number is assumed to always be at the beginning of the file (unlike HDF5). The change is localized to libdispatch/dfile.c See https://support.hdfgroup.org/release4/doc/DSpec_html/DS.pdf Also, it turns out that the code in NC_check_file_type is duplicated (mostly) in the function libsrc4/nc4file.c#nc_check_for_hdf. This branch does the following. 1. Make NC_check_file_type return NC_ENOTNC instead of crashing. 2. Remove nc_check_for_hdf and centralize all file format checking NC_check_file_type. 3. Add proper forward search for HDF5 files (but not HDF4 files) to look for the magic number at offsets of 0, 512, 1024... 4. Add test tst_hdf5_offset.sh. This tests that hdf5 files with an offset are properly recognized. It does so by prefixing a legal file with some number of zero bytes: 512, 1024, etc. 5. Off-topic: Added -N flag to ncdump to force a specific output dataset name.

Revert/Improve nc_create + NC_DISKLESS behavior re: https://github.com/Unidata/netcdf-c/issues/1154 Inadvertently, the behavior of NC_DISKLESS with nc_create() was changed in release 4.6.1. Previously, the NC_WRITE flag needed to be explicitly used with NC_DISKLESS in order to cause the created file to be persisted to disk. Additional analyis indicated that the current NC_DISKLESS implementation was seriously flawed. This PR attempts to clean up and regularize the situation with respect to NC_DISKLESS control. One important aspect of diskless operation is that there are two different notions of write. 1. The file is read-write vs read-only when using the netcdf API. 2. The file is persisted or not to disk at nc_close(). Previously, these two were conflated. The rules now are as follows. 1. NC_DISKLESS + NC_WRITE means that the file is read/write using the netcdf API 2. NC_DISKLESS + NC_PERSIST means that the file is persisted to a disk file at nc_close. 3. NC_DISKLESS + NC_PERSIST + NC_WRITE means both 1 and 2. The NC_PERSIST flag is new and takes over the obsolete NC_MPIPOSIX flag. NC_MPIPOSIX is still defined, but is now an alias for the NC_MPIIO flag. It is also now the case that for netcdf-4, NC_DISKLESS is independent of NC_INMEMORY and in fact it is an error to specify both flags simultaneously. Finally, the MMAP code was fixed to use NC_PERSIST as well. Also marked MMAP as deprecated. Also added a test case to test various combinations of NC_DISKLESS, NC_PERSIST, and NC_WRITE. This PR affects a number of files and especially test cases that used NC_DISKLESS. Misc. Unrelated fixes 1. fixed some warnings in ncdump/dumplib.c
