sun.reflect optionality in OSGi manifest

2

Hi Jonathan, This issue is in reference to npgall/cqengine#94 If typetools marked `sun.reflect` as an optional package in its OSGi manifest, then in case when its functionality required, one would...

Rust 2018 support: `crate::`

2

Attempting to compile this (notice `crate::` prefix in `Error`): ```rust #[macro_use] extern crate derive_error; #[derive(Error)] pub enum Err { A } #[derive(Error)] pub enum Error { SomeErr(crate::Err), } ``` results...

Why does CQE not support Query<O> queries?

2

Is there any specific reason why CollectionQueryEngine#retrieveRecursive only allows SimpleQuery and logical queries and throws an exception on other `Query`-implementing queries?

Problem: PumpkinDB is too low-level

For most end-user cases, PumpkinDB is too "close to the metal" to be easily plugged into a business application, especially if "event sourcing" type of scenarios are considered. Proposed solution:...

Problem: switching storage backends is nearly impossible

Problem: Rust nightly after 2017-06-20 affects benchmarks negatively

Running `cargo bench acker` in the pumpkindb_engine crate: *nightly-2017-06-20*: (last known "good" nightly) ``` test script::tests::ackermann ... bench: 32,562,056 ns/iter (+/- 4,313,209) test script::tests::ackermann_stack ... bench: 24,391,250 ns/iter (+/- 4,758,534)...

Problem: applying words to unexpected values might produce unusual results

4

Suppose one gets types wrong and does something unusual, like using `UINT/ADD` on ints. That won't work right as `UINT` would treat those signed integers as unsigned ones, effectively mistaking...

Currently, [`builtins!`](https://github.com/PumpkinDB/PumpkinDB/blob/master/pumpkindb_engine/src/script/macros.rs#L8-L30) uses `lazy_static!` to prepare `BUILTINS` map of instructions. This means that until `handle_builtins` is first called, nothing is going to get parsed. So if there's, for example, a...
