re: Issue https://github.com/Unidata/netcdf-c/issues/1999
NCclosedir code is incorrect. Fix.
Note that this issue crops up when using a non-VisualStudio windows build
such as Mingw because Mingq defines dirent.h, but Visual Studio does not.
re: github issue https://github.com/Unidata/netcdf-c/issues/1982
The problem was that the libnczarr/zsjon.c handling of strings with
embedded double quotes was wrong; a one line fix.
Also added a test case.
Misc. other changes:
1. I Discovered, en passant, that the handling of 64 bit constants
had an error that was fixed.
2. cleanup of the constant conversion code to recurse on arrays of values.
Re: https://github.com/zarr-developers/zarr-python/pull/716
The Zarr version 2 spec has been extended to include the ability
to choose the dimension separator in chunk name keys. The legal
separators has been extended from {'.'} to {'.' '/'}. So now it
is possible to use a key like "0/1/2/0" for chunk names.
This PR implements this for NCZarr. The V2 spec now says that
this separator can be set on a per-variable basis. For now, I
have chosen to allow this be set only globally by adding a key
named "ZARR.DIMENSION_SEPARATOR=<char>" in the
.daprc/.dodsrc/ncrc file. Currently, the only legal separator
characters are '.' (the default) and '/'. On writing, this key
will only be written if its value is different than the default.
This change caused problems because supporting a separator of '/'
is difficult to parse when keys/paths use '/' as the path separator.
A test case was added for this.
Additionally, make nczarr be enabled default by default. This required
some additional changes so that if zip and/or AWS S3 sdk are unavailable,
then they are disabled for NCZarr.
In addition the following unrelated changes were made.
1. Tested that pure-zarr mode could read an nczarr formatted store.
1. The .rc file handling now merges all known .rc files (.ncrc,.daprc, and .dodsrc) in that order and using those in HOME first, then in current directory. For duplicate entries, the later ones override the earlier ones. This change is to remove some of the conflicts inherent in the current .rc file load process. A set of test cases was also added.
1. Re-order tests in configure.ac and CMakeLists.txt so that if libcurl
is not found then the other options that depend upon it properly
are disabled.
1. I decided that xarray support should be enabled by default for pure
zarr. In order to allow disabling, I added a new mode flag "noxarray".
1. Certain test in nczarr_test depend on use of .dodsrc. In order for these
to work when testing in parallel, some inter-test dependencies needed to
be added.
1. Improved authorization testing to use changes in thredds.ucar.edu
re: https://github.com/Unidata/netcdf-c/issues/1988
There was an issue with certain shell programs (bash notably).
For certain platforms and when given a url that had an escaped
'#' character (e.g. \\#) bash would not remove the backslash. So I
had to add a hack for this. Unfortunately I overdid it and it
removed all '' characters. This is ok for non-windows platforms,
but obviously fails for windows.
The fix is this.
1. In a utility program (ncgen, ncdump, nccopy, etc) there is probably a call (or calls) to NC_backslashUnescape(xxx) where xxx is a path argument from the command line.
2. Replace each such call with NC_shellUnescape(xxx).
The NC_shellUnescape function was added and searched only for occurrences of "\#" and replaces them with "#".
re: https://github.com/Unidata/netcdf-c/issues/1977
PR https://github.com/Unidata/netcdf-c/pull/1753, changed ncgen
to allows certain type names to be used as identifiers in
selected situations.
An unwanted side effect was that existing type aliases no longer
were accepted by ncgen. Specifically, using the "long" type
caused an error.
I was able to figure out a better solution to the original
problem (https://github.com/Unidata/netcdf-c/issues/1750)
that also fixes this problem as well.
This PR fixes that problem in ncgen/ncgen.l,
and adds tests to ncdump/test_keywords.sh
interoperability fixed. We were given a Zarr format dataset
stored as a directory+file tree. This dataset uses the XArray
conventions and was generated by some non-Unidata Zarr implementation.
In attempting to process it with NCZarr, several interoperability
problems were discovered and fixed. This gives us more confidence
that NCZarr -- using pure zarr -- can interoperate with other
Zarr implementations.
Specific changes:
* Add test nczarr_test/run_interop.sh
* Support attributes with single value not enclosed in JSON array tags.
* Add mode inferencing and use it in nczarr_test/run_purezarr.sh
* Reduce size of tst_err_enddef.nc because it is more than 3 GB.
