In order to eventually switch to a single JSON library,
most of the libjsoncpp usage is dropped in favor of rjson.
Unfortunately, one usage still remains:
test/utils/test_repl utility heavily depends on the *exact textual*
format of its output JSON files, so replacing a library results
in all tests failing because of differences in formatting.
It is possible to force rjson to print its documents in the exact
matching format, but that's left for later, since the issue is not
critical. It would be nice though if our test suite compared
JSON documents with a real JSON parser, since there are more
differences - e.g. libjsoncpp keeps children of the object
sorted, while rapidjson uses an unordered data structure.
This change should cause no change in semantics, it strives
just to replace all usage of libjsoncpp with rjson.
This removes the need to include reactor.hh, a source of compile
time bloat.
In some places, the call is qualified with seastar:: in order
to resolve ambiguities with a local name.
Includes are adjusted to make everything compile. We end up
having 14 translation units including reactor.hh, primarily for
deprecated things like reactor::at_exit().
Ref #1
Alternator and CDC, apart from enabling their experimental features,
need to have their schema extensions registered. This patch adds missing
registration of schema extensions to cql_repl, so that cql tests written
with Alternator or CDC in mind will properly work.
cql_repl is a simple program which reads CQL from stdin,
executes it, and writes results to stdout.
It support --input, --output and --log options.
--log is directed to cql_test.log by default.
--input is stdin by default
--output is stdout by default.
The result set output is print with a basic
JSON visitor.
