`validate_options` needs to be extended with
`topology` parameter, because NetworkTopologyStrategy needs to validate if every
explicitly listed DC is really existing. I did cut corner a bit and
trimmed the message thrown when it's not the case, just to avoid passing
and extra parameter (ks name) to the `validate_options`
function, as I find the longer message to be a bit redundant (the driver will
receive info which KS modification failed).
The tests that have been commented out in the previous commit have been
restored.
The check for `replication_factor` tag in
`network_topology_strategy::validate_options` is redundant for 2 reasons:
- before we reach this part of the code, the `replication_factor` tag
is replaced with specific DC names
- we actually do allow for `replication_factor` tag in
NetworkTopologyStrategy for keyspaces that have tablets disabled.
This code is unreachable, hence changing it to an internal error, which
means this situation should never occur.
The place that unrolls `replication_factor` tag checked for presence of
this tag ignoring the case, which lead to an unexpected behaviour:
- `replication_factor` tag (note the lowercase) was unrolled, as
explained above,
- the same tag but written in any other case resulted in throwing a vague
message: "replication_factor is an option for SimpleStrategy, not
NetworkTopologyStrategy".
So we're changing this validation to accept and unroll only the
lowercase version of this tag. We can't ignore the case here, as this
tag is present inside a json, and json is case-sensitive, even though the
CQL itself is case insensitive.
Added a test that passes for both scylla and cassandra.
Fixes: #15336
Most of the code from `recognized_options` is either incorrect or lacks
any implementation, for example:
- comments for Everywhere and Local strategies are contradictory, first
says to allow all options, second says that the strategy doesn't accept
any options, even though both functions have the same implementation,
- for Local & Everywhere strategies the same logic is repeated in
`validate_options` member functions, i.e. this function does nothing,
- for NetworkTopology this function returns DC names and tablet options, but tablet
options are empty; OTOH this strategy also accepts 'replication_factor'
tag, which was ommitted,
- for SimpleStrategy this function returns `replication_factor`, but this is also validated
in `validate_options` function called just before the removed
function.
All of it makes `validate_replication_strategy` work incorrectly.
That being said, 3 tests fail because of this logic's removal, so it did
something after all. The failing tests are commented out, so that the CI
passes, and will be restored in the next commit(s).
Python and Python developers don't like directory names to include a
minus sign, like "cql-pytest". In this patch we rename test/cql-pytest
to test/cqlpy, and also change a few references in other code (e.g., code
that used test/cql-pytest/run.py) and also references to this test suite
in documentation and comments.
Arguably, the word "test" was always redundant in test/cql-pytest, and
I want to leave the "py" in test/cqlpy to emphasize that it's Python-based
tests, contrasting with test/cql which are CQL-request-only approval
tests.
