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`
* ops: fix unlock_time, chain_height
* `BlockInfoV{1,2,3}` -> `BlockInfo`
* constants: add `DATABASE_VERSION`
* database: add `DatabaseRw::update()`
* output: use `DatabaseRw::update()` in `remove_output()`
* add `TxBlobs` table, ignore pruning tables
* block: mostly impl `add_block()` body
* ops: comments
* add_block: miner v2 tx commitment, height cast
* block: impl `pop_block()`
* block: mostly impl `get_block()`
* 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
Co-authored-by: Boog900 <boog900@tutanota.com>
* `cumulative_generated_coins()` docs for pre-block-0 special case

database: impl service::{Request,Response} mappings (#101)
* add `cuprate-types`
* remove `cuprate_database::service::{request,response}`
* use `cuprate_types::service::{request,response}`
* service: fix `Request` `match`'s
* service: create `ReadRequest` function mappings
* service: create `WriteRequest` function mappings
* service: add rough `WriteRequest` retry loop
* service: handle `RuntimeError::ResizeNeeded` in writer
* add `{R,r}o` exception to typos
* docs
* env: make `resize_map()` return new memory map byte size
* write: proactively handle resizes
`add_block()` takes `VerifiedBlockInformation` such
that it can just take the inner blobs of data.
This is a problem when reactively resizing since we no longer
have the block struct we just gave away so we're forced to `.clone()`
each retry.
Instead of that - we will proactively resize so the resize error
will never occur in the first place.
* read: use type aliases
* docs
* fix import
* write: handle resizes reactively
* service: panic if response can't be sent back
* write: add loop unreachable asserts
* service: print and drop error instead of panic
* write: fix retry loop off-by-1
* write: fix docs
* review changes
* update readme
* remove `BlockBatchInRange` request/response
* Update database/README.md

database: impl trait function bodies for heed & redb (#85)
* env: remove `T: Table` for `Env::create_tables()`
It creates _all_ tables, not a specific `T: Table`
* heed: half impl `Env::open()`, some TODOs
* heed: add `HeedTxR{o,w}<'env>`
* workspace/cargo: add `parking_lot`
* remove `parking_lot`
`MappedRwLockGuard` doesn't solve the `returning reference to
object owned by function` error when returning heed's lock guard
+ the tx so we'll be going with `std`
* env: add `{EnvInner,TxRoInput,TxRwInput}` and getter `fn()`s
* env: fix tx <-> table lifetimes, fix `Env::create_tables()`
* heed: impl `DatabaseRo`
* heed: impl `DatabaseRw`
* database: add `src/backend/${BACKEND}/tests.rs`
* heed: impl more of `Env::open()`
* redb: fix trait signatures, add `trait ValueGuard`
* accommodate `DatabaseRo` bounds for both `{heed,redb}`
* fold `get_range()` generic + bounds
* add `TxCreator`, add `heed` tests
* env: `TxCreator` -> `EnvInner` which doubles as DB/Table opener
* database: `DatabaseRw<'tx>` -> `DatabaseRw<'db, 'tx>`
* heed: `db_read_write()` test
* database: fix `get()` lifetimes, heed: add `db_read_write()` test
* database: remove `'env` lifetime from `DatabaseRo<'env, 'tx>`
not needed for immutable references
* redb: fix new `{Env, EnvInner, DatabaseR{o,w}}` bounds
* redb: impl `Database` traits
* redb: impl `TxR{o,w}` traits
* redb: impl `Env`
* redb: open/create tables in `Env::open`

* redb: fix alignment issue with `Cow` and `from_bytes_unaligned()`
* redb: only allocate bytes when alignment != 1
* heed: remove custom iterator from `range()`
* storable: conditionally allocat on misaligned bytes in `from_bytes`
* add database guard
* database: AccessGuard -> ValueGuard
* storable: add `ALIGN` and `from_bytes_unaligned()`
* redb: 1 serde type `StorableRedb`, fix impl
* cow serde, trait bounds, fix backend's where bounds
- Uses Cow for `redb`'s deserialization
- Conforms `heed` to use Cow (but not as the actual key/value)
- Conforms the `cuprate_database` trait API to use Cow
- Adds `ToOwned + Debug` (and permutation) trait bounds
- Solves 23098573148968945687345349657398 compiler errors due
to aforementioned trait bounds, causing `where` to be everywhere
* fix docs, use fully qualified Tx functions for tests
* backend: check value guard contains value in test
* add `Storable::ALIGN` tests, doc TODOs
* add `trait ToOwnedDebug`
* traits: `ToOwned + Debug` -> `ToOwnedDebug`

* separate `config.rs` -> `config/`
* ci: combine tests, run both `heed` and `redb` tests

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:🧵: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... https://docs.rs/heed/0.20.0-alpha.9/src/heed/env.rs.html#772 * free: impl `resize_memory_map()` * free: docs * env: add `disk_size_bytes()` * config: impl `From<$num>` for `ReaderThreads` * move `fs`-related constants to `cuprate_helper::fs` * docs * add `resize.rs`, `ResizeAlgorithm` * env: use `ResizeAlgorithm` in `resize_map()` * TODO: account for LMDB reader limit * resize: docs, add `page_size()`, impl `fixed_bytes()` * resize: impl `percent()` * resize: docs * env: take `ResizeAlgorithm` by value (it impls `Copy`) * heed: TODO for `MDB_MAP_FULL` & `MDB_MAP_RESIZED` * config: `From<Into<usize>>` for `ReaderThreads` Co-authored-by: Boog900 <boog900@tutanota.com> * env: move mutual exclusion doc to backend * free: update invariant doc Co-authored-by: Boog900 <boog900@tutanota.com> * Update database/src/service/mod.rs Co-authored-by: Boog900 <boog900@tutanota.com> * fix `[allow(unused_imports)] // docs` * move DB filename from `helper/` -> `database/` * config: use `DATABASE_FILENAME` * config: add `db_file_path()` * lib: add non-`service` usage invariant docs * table: seal `Table` trait, impl for all `crate::tables` * fix docs * fix docs pt.2 --------- Co-authored-by: Boog900 <boog900@tutanota.com> |

database: Errors (#62)
* error: add variants to `RuntimeError`
* error: remove `<BackendError>` generic
we can just map each backend error variant <-> our error as needed
* backend: impl `From<heed::Error>` for `RuntimeError`
* add `Never` type to allow foreign trait implementations
This is a newtype to workaround `sanakirja::Storable` not being
able to be implemented on `std::convert::Infallible` due to
"foreign trait on foreign type" rules.
* revert

initial database code (#6)
* commit to start the draft pull request. added a space * Please don't look to close.It might hurt your eyes * impl associated types * errors, docs & divided ro/rw tx Added some more errors to DB_FAILURES, rewrited crates docs, and specified WriteTransaction subtype which implement write mode method. * more changes see description changed blockchain_db folder by database. Implemented (just for test) get_block_hash, open, from to Interface. Also rewrited a declarative macro for tables. Will have to add Dummy Tables later. * small changes * Organized modules & implemented get_block_hash * write prototype & error Added prototype functions for clear(), put() & delete() in mdbx implementation. They still don't consider table flags. Also added a temporary DB_FAILURES::EncodingError for monero-rs consensus_encode errors. Still have to rethink about it to resend a reference to the data that can't be encoded. * Multiple changes - hse.rs Added hse.rs that will contain db implementations for HSE. Since the codebase can't welcome unsafe code, the wrapper will be written outside of the project. - lib.rs Added a specific FailedToCommit error. (will investigate if really necessary). Added DupTable trait, which is a Table with DUPSORT/DUPFIXED support and its declarative macro. Added two other tables, blockheaders that give block's header with specified hash & blockbody that give block's body with specified hash Added Cursor methods, that are likely to be deprecated if I found a way to implemen Iterator on top of it. Added WriteCursor trait & methods, which is basically put & del. Added mandatory type for Cursors in Transaction & WriteTransactions Refactored get_block_hash interface method. - mdbx.rs Added partial implementation of Cursor & WriteCursor trait for libmdbx::Cursor. Only the first() & get() methods are implemented Added implementation of get & commit for Transaction * put mdbx as features with its dependency * save * refactored some method with macros * more mdbx errors, docs correction, moved to error.rs * finish nodup mdbx impl, errors.rs, macros, tables Finished the initial implementation of Cursor, WriteCursor, Transaction and WriteTransaction in mdbx.rs. Corrected some macros in mdbx.rs to simplify the implementations. There is certainly rooms to more flexible macros. Also added 3 other tables. I started to divide errors into category to more easily handle them at higher-level. Due to the large number of errors i just moved them into another file. There is know DB_SERIAL enum for errors relating of decoding/encoding error & DB_FULL enum for every errors relating a component being overeaching its capacity. * bye bye match statement in mdbx.rs * defined all blockchain tables (not txpool) * dupsort/fixed support, dupcursor, basic block interface * tables, types, encoding and documentations Redefined all the database types from @Boog900's monero-rs db branch and added the needed implementations. The database now use bincode2 for encoding and decoding. We observe that bincode was 5 times faster at serializing than monero::consensus_encode. Since we still use monero-rs types but can't implement foreign trait to them, the encoding module contain a compatibility layer, the time we switch from monero-rs to properly implement it. All the tables are now defined. (can be subject to change if there is good reason for). added documentations to modules and types. * replaced macros and added hfversion table * save * multiple changes * modified database schema. deprecated output global index and splited up pre-rct from rct output. * Fixed DupCursor function to return subkey (thx to rust turbofish inference). * Added some output functions * Added two new DB_FAILURES, one to handle a prohibited None case and one for undefined case where a dev msg is needed. * fixed TxOutputIdx, previously used global index, now is a tuple of amount/amount_index. * i hate lifetimes * read-only method now use read-only tx * initial output fn * some tx functions. Yes I'll refactor them * moved interface in a module * redefined errors, more tx fn, None->error * corrected a table + started blk fns * save * fixed TxOutputIdx + pop_block * IIRC I finished initial interface fns * fixed table name const + db build/check/open fn * switched important tables to dummy keys + rm blockhfversion * minor docs correction * fixed mentioned issues * make a test bin, just for fun * fixed issues + cargo fmt * removed monerod part * fixed a comment |
