- Remove the e2e that did concurrent mgp_* calls on the same transaction
(ATM this is unsupported)
- Fix up the concurrent mgp_global_alloc test to be testing it more precisely
- Reduce the memory limit on detach delete test due to recent memory
optimizations around deltas.
- No longer throw from hook, through jemalloc C, to our C++ on other
side. This cause mutex unlocks to not happen.
- No longer allocate error messages while inside the hook. This caused
recursive entry back inside jamalloc which would try to relock a
non-recursive mutex.
* Add AUTH system tx deltas
* Add auth data RPC and handlers
* Support multiple system deltas in a single transaction
* Added e2e test
* Bugfix: KVStore segfault after move

* Split queries into system and data queries
* System queries are sequentially executed and generate separate transaction deltas
* System transaction try locks for 100ms
* last_commited_system_ts saved to DBMS durability
* Replicating CREATE/DROP DATABASE
* Sending a system snapshot if REPLICA behind
* Passing a copy of the gatekeeper::access as std::any to all functions that could call an async execution
* Removed delete_on_drop flag (we now always delete on drop)
* Using UUID as the directory name for databases
* DBMS durability update (added versioning and salient information)
* Automatic migration from previous version
* Interpreter can run some queries without a target database
* SHOW REPLICA returns the status of the currently active DB
* Returning UUID instead of db name in the RPC responses
* Using UUIDs for database specification in RPC (not name)
* FrequentCheck forces update on reconnect
* TimestampRpc will detect if a replica is behind, and will update client's state
* Safer SLK reads
* Split SHOW DATABASES in two SHOW DATABASES (list of current databases) and SHOW DATABASE a single string naming the current database
