database: implement `ops/` (#102)
* ops: add `trait MoneroR{o,w}`
* update `trait MoneroR{o,w}` bounds
* types: add `BlockInfoLatest` type alias
* block: impl most core functions
* types: fix https://github.com/Cuprate/cuprate/pull/91#discussion_r1527668916
* fix table type test
* cargo.toml: add `{cuprate-types, monero-serai}`
* add_block: add all other block data
* ops: remove unneeded `block` functions
* env: add `EnvInner::open_db_rw_all()`
* types: fix test
* block: `&mut TxRw` -> `&TxRw`, use `open_db_rw_all()`
* add `trait Tables[Mut]` and use it in `EnvInner`
* block: use `TablesMut`
* tables: replace manual impl with `define_trait_tables!()`
* tables: docs for `trait Tables[Mut]`
* tables: doc functions
* create `call_fn_on_all_tables_or_early_return!()` macro
* block: cleanup signatures + bodies
* block: more fn's, docs
* block: add `doc_{error,single,bulk}!()`
* remove `ops/monero.rs`
* move `height()` to `ops/blockchain.rs`
* add `ops/macros.rs`
* tx: add fn signatures
* output: fix fn signatures
* ops: expose `_inner()` functions
* block: add `add_block_header{_bulk, _inner}()`
* ops: remove doc_{fn,inner}!()`
* ops: remove `_{inner,bulk}()`, lifetime + generics
* update lib/mod docs
* ops: add and use `doc_add_block_inner_invariant!()`
* ops: add docs/return to inner `add_block()` functions
* add_block(): extract and use fn for {key_image, output}
* ops: more fn body impl + `add_block()`
* cargo: add `monero-pruning`
* ops: extract out `tx` functions from `add_block()`
* property: add `db_version()`
* ops: `pop_block()` body, remove other `pop_block` fn's
* types: add `block_blob: Vec<u8>` to `VerifiedBlockInformation`
* block: put `block_blob`, pass `Tables` to sub-functions
`impl TablesMut` can't mutably pass multiple tables since
it takes `&mut self`, so all functions unfortunately have to
take a full `&mut impl TablesMut` even though they only need
a few tables.
* database: add `DatabaseRw::take()`
useful for `pop_block()` where we need the value afterwards
* block: deserialize tx's from `block_blobs` in `pop_block()`
* blockchain: `height()` -> `chain_height()`
* output: fix `amount_index`

* block: impl `get_block_{from_height,header,header_from_height}`
* add `OutputFlags` bitflags
* add_block: u32::try_into(height: u32), use `OutputFlags`
* tx: impl `get_{tx,tx_from_id}()`
* tx: move docs tests to `#[test]`
testing everything in 1 go is more natural since e.g:
`add_tx()` is followed by `get_tx()`
* tables: add `trait TablesIter`, `all_tables_empty()`
This allows `TablesMut` to be a superset of `Tables`
and use all its accessor functions.
* use cuprate-test-utils, fix tx tests
* block: `add_block()` take block by ref
* tx: use all txs in tests
* output: add `all_tx_functions()` test
* add_block: check current height against input
* block: map more fields in `get_block()`
* block: remove `get_block()`, doc tests, fix `get_block_header()`
* block: dummy values in test
* heed: use `last/first()` instead of `unsafe` cursors
We no longer have DUP semantics and also hard to debug errors
were popping up on `del_current()`...
* heed: fix `DatabaseRw::delete`
Ok(true) means the key did not exist, so we must return
Err(RuntimeError::KeyNotFound)
* block: `add_block()` (dummy value) test
* ops: `key_image` tests
* cleanup, docs, tests
* backend: test `take()` & `update()`
* docs
* remove `OutputFlags::NONE`
* add_block(): add asserts, panic docs, `should_panic` tests
* backend: remove `Ok(())` in `Database::delete` if already deleted
redb already does this, so heed so match
* block: move block operations after tx/outputs
* `amount == 0` -> `amount == 1`
* Nit: StorableVec::wrap_ref
* `saturating_sub(1)` -> `- 1`
* add `TxOutputs` table
* add_block(): add to `tx_outputs` table
* fix `DatabaseRo::update`
* add_tx(): take `block_height` as input
* tx: add/remove from `TxOutputs` table
* output: remove if `amount == 1` -> `amount_index == 0`
* output: fix `add_output()`'s `amount_index` calculation
* output: fix `add_output()`'s `amount_index` calculation again
* output: tests for `amount_index/num_outputs`
* block: `num_outputs - 1` and `take()` -> `get()`
We don't need to `take()` since the call afterwards to
`remove_output()` removes the entry
* block: swap `get_block_extended_header[_from_height]()`
* move `{key_image,output}` handling `add_block()` -> `add_tx()`
* blockchain: add doc to `top_block_height()`
* block: manual panic -> `assert_eq!()`
* test-utils: add `block_blob` to `VerifiedBlockInformation`
field introduced in this PR
* ops: use real block/tx data in tests
* block: `total_generated_coins` -> `cumulative_generated_coins`
* fix clippy, docs, TODOs
* `cumulative_generated_coins()`: `block/` -> `blockchain/`
* blockchain: add `cumulative_generated_coins()` tests
* Update database/src/ops/block.rs

#[cfg(test)]

database: Resizes, Shutdown, Flushing (#68)
* error: add `NeedsResize`
accidently removed, was `MapFull` before.
We need this because we as the writer thread must
react to this error in order to resize.
The writer thread doesn't have access to `heed::Error`, but
`Runtime::Error`, so this variant must exist
* env/backend: add `MANUAL_RESIZE` and `resize()`
* heed: respect `ReadersFull`, comment errors
* free: add `resize_memory_map()`
* env: add `Env::current_map_size`
* service: add `resize_map()`
* database: make `Env` itself cheaply clonable + threadsafe
`heed::Env` already uses `Arc` internally, but `sanakirja` does
not, so abstract this at the `Env` level instead of wrapping
`ConcreteEnv` in `Arc` ourselves.
* service: `Arc<ConcreteEnv>` -> `ConcreteEnv: Clone`
* env: add `SYNCS_PER_TX`, `path()`, `shutdown()`
* database: add `src/service/state.rs`
* service: add to `state.rs`, add `DatabaseState` to readers/writer
* add `parking_lot`
Okay, turns out we need to take locks in
`database/src/service/state.rs`...
`std`'s lock fairness policies are not well defined and
depend on the OS implementation, `parking_lot` on the other hand
has a fairness policy which is important when the writer needs
the lock but readers keep pouring in, essentially never letting
the writer do stuff.
* state: use `crossbeam::atomic::AtomicCell`
We have crossbeam as a dep anyway.
* heed: `heed::Env` -> `Arc<RwLock<heed::Env>>`
* service: add reader shutdown handle, use `Select` for msgs
* service: remove `state.rs`
We don't need this, we will represent shutdowns with channel
messages and `Select`, and mutual exclusion with a `RwLock`.
* service: fix misc reader/writer stuff
* database: add `config.rs`
* service: use `ReaderThreads` when spawning readers
* service: impl `shutdown()` for readers/writer
* service: return `DatabaseReaderReceivers` on shutdown via `JoinHandle`
Solves the issue of unfortunately timed `Request`s
that come in _right_ as we are shutting down.
If we (Cuprate) drop the database channels too early the requesting
thread will probably panic as they probably use `.unwrap()`,
never expecting a channel failure.
Returning this structure containing all the channels allows the
final shutdown code to carry these channels until the very end
of the program, at which point, all threads exit - no panics.
* remove `parking_lot`
Could be used as the database mutual exclusion lock.
Needs to be tested against `std`.
* config: add `path`
* env: `path()` -> `config()`, backend: impl `Drop`
* `Arc<ConcreteEnv>`, shutdown `service` on channel disconnect
* backend: add `Config` to `ConcreteEnv`
* service: use `std::thread::Builder` for readers/writer
* config: `PathBuf` -> `Cow<'static, Path>`
* misc docs, remove `RuntimeError::ShuttingDown`
* service: init & shutdown docs
* heed: impl `Env::resize_map()`
* heed: impl `Env::current_map_size()`
* lib.rs: add example crate usage test
* heed: `RwLock` comment
* helper: add `cuprate_database_dir()`
* config: use `cuprate_database_dir()`
* lib.rs: TODO example test
* database: add `page_size`
The database memory map size must be a multiple of
the OS page size. Why doesn't `heed` re-expose this?
It calls it when checking anyway...
