Tests for Column of Arrays (heavydb-internal PR 6571).

2

As in the title (https://github.com/heavyai/heavydb-internal/pull/6571) plus various updates to make tests pass with the latest heavydb master.

When heavyai tries to run queries, it should check with rbc process if there are any new runtime UDFs defined and trigger the registration when needed.

Example: ``` >>> @omnisci('int32(TableFunctionManager, Column, T, OutputColumn)', T=['int32', 'int64', 'float32', 'float64']) ... def colincr(mgr, input, di, output): ... mgr.set_output_row_size(input.size()) ... for i in range(input.size()): ... output[i] = input[i] + di...

Here is a list of environment variables that we should document: - HEAVYDB_CLIENT_CONF - see rbc/heavydb.py:get_client_config - RBC_TESTS_FULL - see rbc/tests/heavyai/test_heavyai.py - OMNISCIDB_DEV_LABEL - see rbc/tests/__init__.py (requires rebranding) _Originally posted...

Support raising exceptions from OmnisciDB UDFs

Currently, the UDFs send the error messages to omniscidb server stdout but rbc users cannot see there. So, we need to find a way to return the error messages to...

The issue is created to log unexplained rbc CI failures.

Use TargetInfo for deciding which additional libraries need to be registered to remote target/typing context.

Currently, there are two remote JIT classes: - RemoteOmnisci as defined in omniscidb.py that produced LLVM IR should never contain Python C/API calls. - RemoteJIT as defined in remotejit.py that...

When having a live ibis connection `con`, RBC RemoteOmnisci should use the same connection. Workaround: ``` omnisci = RemoteOmnisci(host=con.host, port=con.port, dbname=con.db_name) omnisci._session_id = con.session_id ``` Implement: ``` omnisci = RemoteOmnisci(connection=con)...

``` @omnisci('uint32(uint32)') def foo(i): return i omnisci.register() ``` fails: ``` rtype = ext_arguments_map[sig[0].tostring( > use_annotation=False)] E KeyError: 'uint32' rbc/omniscidb.py:698: KeyError ``` Implement better error handling when users try to use...
