Periodic update of the internal tinyxml2 code for processing
XML. This also required some changes to the "tinyxml2" target
in libncxml/Makefile.am to modify the code to compile in the
netcdf-c environment.
One of the changes in df3636b introduced the ability to filter log
messages by level. This fixes a typo that flipped the intended
filtering, so that `NCLOGOFF` _enabled_ all messages instead of
_disabling_ them.
Prior to this PR, DAP4 always fetched the whole (constrained) dataset
This PR changes the query processing so
1. It reads data on a per-variable request (equivalent to calling nc_get_var()).
2. It tracks a response for every query.
Most of the changes reflect having to do per-variable requests.
In any case, doing all this significantly reduces the amount of data transmitted and hence speeds up DAP4 requests.
re: Issue https://github.com/Unidata/netcdf-c/issues/2752
The authorization setup when using a proxy is apparently not
being used, or used incorrectly.
This PR ensures that the relevant curl options, specifically
CURLOPT_VERIFYHOST and CURLOPT_VERIFYPEER, are properly setup.
As part of this, the ability to turn off these options was fixed.
Note that no testing of this PR is currently possible because we
do not have access to a proxy.
re: Issue https://github.com/Unidata/netcdf-c/issues/2748
This PR fixes a number of issues and bugs.
## s3cleanup fixes
* Delete extraneous s3cleanup.sh related files.
* Remove duplicate s3cleanup.uids entries.
## Support the Google S3 API
* Add code to recognize "storage.gooleapis.com"
* Add extra code to track the kind of server being accessed: unknown, Amazon, Google.
* Add a new mode flag "gs3" (analog to "s3") to support this api.
* Modify the S3 URL code to support this case.
* Modify the listobjects result parsing because Google returns some non-standard XML elements.
* Change signature and calls for NC_s3urlrebuild.
## Handle corrupt Zarr files where shape is empty for a variable.
Modify behavior when a variable's "shape" dictionary entry.
Previously it returned an error, but now it suppresses such a variable.
This change makes it possible to read non-corrupt data from the file.
Also added a test case.
## Misc. Other Changes
* Fix the nclog level handling to suppress output by default.
* Fix de-duplicates code in ncuri.c
* Restore testing of iridl.ldeo.columbia.edu.
* Fix bug in define_vars() which did not always do a proper reclaim between variables.
