* Pre: Implement batch [a v] pair lookup.
* Pre: Add InternSet for sharing ref-counted handles to large values.
* Pre: Derive more for Entity.
* Pre: Return DB from creating; return TxReport from transact.
I explicitly am not supporting opening existing databases yet, let
alone upgrading databases from earlier versions. That can follow fast
once basic transactions are supported.
* Pre: Parse string temporary ID entities; remove ValueOrLookupRef.
This adds TempId entities, but we can't disambiguate String temporary
IDs from values without the use of the schema, so there's no new value
branch. Similarly, we can't disambiguate lookup-ref values from two
element list values without a schema, so we remove this entirely.
We'll handle the ambiguity later in the transactor.
* Persist partitions to SQL store; allocate transaction ID. (#186)
* Post: Test upserting with vectors.
This converts an existing test to EDN:
84a80f40f5/test/datomish/db_test.cljc (L193).
* Implement tempid upsert resolution algorithm. (#184)
* Post: Separate Tx out of DB.
This is very preliminary, since we don't have a real connection type
to manage transactions and their metadata yet.
* Post: Comment on implementation choices in the transactor.
* Review comment: Put long use lists on separate lines.
* Review comment: Accept String: Borrow<S> instead of just String.
* Review comment: Address nits.
* Move Schema from mentat_db to mentat_core.
* Define SchemaMap in terms of Entid, not i64.
* Add Schema::{is_attribute,identifies_attribute}.
* Add pointer to #291.
* Don't pass around 64-bit pointers to 64-bit integers.
* Leave a pointer to issue 288.
* Re-export mentat_db::types::DB from mentat_db.
* Parse EDN strings in the query parser.
* Export 'public' API from mentat_query_parser's top level.
* Stub out mentat::q_once.
* Pre: Add some value conversion tests.
This is follow-up to earlier work. Turn TypedValue::Keyword into
edn::Value::NamespacedKeyword. Don't take a reference to
value_type_tag.
* Pre: Add repeat_values.
Requires itertools, so this commit is not stand-alone.
* Pre: Expose the first transaction ID as bootstrap::TX0.
This is handy for testing.
* Pre: Improve debug module.
* Pre: Bump rusqlite version for https://github.com/jgallagher/rusqlite/issues/211.
* Pre: Use itertools.
* Start implementing bulk SQL insertion algorithms. (#214)
This is slightly simpler re-expression of the existing Clojure
implementation.
* Post: Start generic data-driven transaction testing. (#188)
* Review comment: `use ::{SYMBOL}` instead of `use {SYMBOL}`.
* Review comment: Prefer bindings_per_statement to values_per_statement.
* Make Variable::from_symbol public.
* Implement basic parsing of queries.
* Use pinned dependencies the hard way to fix Travis.
* Bump ordered-float dependency to 0.4.0.
* Error coercions to use ?, and finishing the find interface.
* Start installing the SQLite store and bootstrapping the datom store.
* Review comment: Decomplect V2_IDENTS.
* Review comment: Decomplect V2_PARTS.
* Review comment: Pre: Expose Clojure's merge on Value instances.
* Review comment: Decomplect V2_SYMBOLIC_SCHEMA.
* Review comment: Decomplect V1_STATEMENTS.
* Review comment: Prefer ? to try!.
* Review comment: Fix typos; format; add TODOs.
* Review comment: Assert that Mentat `Schema` is valid upon creation.
* Review comment: Improve conversion to and from SQL values.
This patch factors the fundamental SQL conversion maps
between (rusqlite::Value, value_type_tag) and (edn::Value, ValueType)
through a new Mentat TypedValue. (A future patch might rename this
fundamental type mentat::Value.)
To make certain conversion functions infallible, I removed
placeholders for :db.type/{instant,uuid,uri}. (We could panic
instead, but there's no need to do that right now.)
* Review comment: Always uses bundled SQLite in rusqlite.
This avoids (runtime) failures in Travis CI due to old SQLite
versions. See 432966ac77.
* Review comment: Move semantics in `from_sql_value_pair`.
* Review comment: DB_EXCISE_BEFORE_T instead of ...BEFORET (no underscore).
* Review comment: Move overview notes to the Wiki.
