The fields of ROUTE message were not read from the input buffer, thus the
input buffer got corrupted. Sending a new message to the server would result
reading the remaining fields from the buffer, which means reading some values
instead of message signature. Because of this unmet expectation, Memgraph closed
the connection. With this fix, the fields of the ROUTE message are properly
read and ignored.
Add a report for the case where a sync replica does not confirm within a timeout:
-Add a new exception: ReplicationException to be returned when one sync replica does not confirm the reception of messages (new data, new constraint/index, or for triggers)
-Update the logic to throw the ReplicationException when needed for insertion of new data, triggers, or creation of new constraint/index
-Add end-to-end tests to cover the loss of connection with sync/async replicas when adding new data, adding new constraint/indexes, and triggers
Add end-to-end tests to cover the creation and drop of indexes, existence constraints, and uniqueness constraints
Improved tooling function mg_sleep_and_assert to also show the last result when duration is exceeded
Add a new command that is able to return the set of configurations that that the
given instance of memgraph was started up with. The returned information
currently consists of the name, the default and the current value of each flag.
The hidden property of three flags were removed, namely --query-cost-planner,
--query-vertex-count-to-expand-existing and --query-max-plans. The flag
--log-link-basename was completely removed since it is not used.
The `sum()` and `count()` functions were giving results different from the openCypher specification on null `input.` The aggregation functions also had a problem when they were used in a group-by context and were giving results that were not compliant with the openCypher specification.
* Make `IfOperator` return the `else_expression_` in case of `NULL`
* Add gql_behave tests
* Add gql_behave test to specifically check for the case when the test expression itself is null
* Modify `toString` to be able to handle `Date`, `LocalTime`, `LocalDateTime` and `Duration`
* Add unit tests
* Make `operator<<` use the `ToString()` implementations
* Add tests to verify the correctness of negative durations
* Add more tests to look for cases when the individual duration entities overflow.
* Storage takes care of the saving of setting when a new replica is added
* Restore replicas at startup
* Modify interactive_mg_runner + memgraph to support that data-directory can be configured in CONTEXT
* Extend e2e test
* Correct typo
* Add flag to config to specify when replication should be stored (true by default when starting Memgraph)
* Remove un-necessary "--" in yaml file
* Make sure Memgraph stops if a replica can't be restored.
* Add UT covering the parsing of ReplicaStatus to/from json
* Add assert in e2e script to check that a port is free before using it
* Add test covering crash on Jepsen
* Make sure applciaiton crashes if it starts on corrupted replications' info
Starting with a non-reponsive replica is allowed.
* Add temporary startup flag: this is needed so jepsen do not automatically restore replica on startup of main. This will be removed in T0835
* Add test
* Add implementation and adapted test
* Update workloads.yaml to have a timeout > 0
* Update tests (failing due to merging of "add replica state")
* Adding "raw message" column to the result return by CHECK STREAM query
* Update way results of CHECK STREAM are built
* Adapting CHECK STREAM integration tests (Pulsar/Kafka) to run with new result structure
* Adding new tests covering the check stream functionality
* Uppercase constants in stream tests
* Reformat f-strings
* Moving function add_query_module from CMakeLists from tests/e2e/magic_functions to tests/e2e
* Adding failing test copying behavior when loading c module (.so) into memgraph.
* Fixing issue where NO_ERROR status returned MgpTransAddFixedResult was converted to false
* Removing unnecessary transformation
* removing incorrect parameterization of test
* re-adding parametrized transformation
