Update utf8proc.[ch] to use the version now
maintained by the Julia Language project
(https://github.com/JuliaLang/utf8proc/blob/master/LICENSE.md).
The license for the previous version was
unacceptable for the Debian and Ubuntu release
systems. The new version both updates the code
and addresses the license issue.
It turns out that the utf8proc software we are using
was turned over to the Julia Language developers
and the license terms changed to allow modification.
(https://github.com/JuliaLang/utf8proc/blob/master/LICENSE.md).
So the fix here is as follows:
1. Wrap the library with a fixed interface: libdispatch/dutf8.c
and include/ncutf8.h.
2. Replace the existing utf8proc code with the new version
from https://github.com/JuliaLang/utf8proc.
3. Add a couple more test cases: nc_test/tst_utf8_validate.c
and nc_test_utf8_phrases.c. If/when I can find a usable
normalization test, I will incorporate that later.
The problem is that the name was being updated prior to the old
variable being removed from the hashmap. It checks whether the key and
the name of the variable being removed match, but since the name had
already been updated, the names did not match so the variable was not
removed. This patch removes the variable from the hashmap first,
then updates the name, and then adds the variable with the new name to
the hashmap.
Similar change for renaming dimensions.
The addition of the nc_hashmap to facilitate quick
retrieval of var and dim by name did not take into
account key collisions -- two or more names hashed
to the same value. If the keys matched, it assumed
that the names matched also.
This change fixes this incorrect assumption and
checks both the key (which is the hash of the name)
and if the keys match, it also checks that the names
match.
While there have been no instances of duplicate keys,
they are certain to occur and cause difficult to
debug issues. This fix eliminates that defect.
NetCDF-c Github issue #185
The code in libsrc/dim.c has not been upgraded to support
CDF-5 format.
Rule we are implementing sets the max dimension sizes as follows:
Classic: CDF-1 NC_MAX_INT - 3 = 2147483647 - 3
64 bit Offset: CDF-2 NC_MAX_UINT - 3 = 4294967295 - 3
64 bit Data: CDF-5 NC_MAX_UINT64 - 3 = 18446744073709551615 - 3
The -3 is to handle rounding.
contain as little file-type specific info as possible. It
modifies especially libsrc so that all of the netcdf-3 data
that used to be in struct NC is now kept in a separate chunk
of data pointed to by the struct NC. This makes all of
current protocols consistent: netcdf-3, netcdf-4, and dap.
