This is a big deck-chair re-arrangement. This puts FindQuery into
query-algebrizer and puts the validation from ParsedFindQuery ->
FindQuery their as well.
Some tests were re-homed for this.
In addition, the little-used maplit crate dependency was replaced with
inline expressions.
* Make properties on NamespacedKeyword/NamespacedSymbol private
* Use only a single String for NamespacedKeyword/NamespacedSymbol
* Review comments.
* Remove unsafe code in namespaced_name.
Benchmarking shows approximately zero change.
* Allow the types of ns and name to differ when constructing a NamespacedName.
* Make symbol namespaces optional.
* Normalize names of keyword/symbol constructors.
This will make the subsequent refactor much less painful.
* Use expect not unwrap.
* Merge Keyword and NamespacedKeyword.
First, the parser had a small grouping bug where-by it wouldn't parse
Z as timezone correctly. Second, we weren't printing instants in the format
that we parse.
Fixes from @kevinmehall.
* Prefer character sets over backtracking in the EDN parser.
* Avoid duplicate effort when parsing floats in the EDN parser.
* Clean up duplicate position tracking code.
This turns out to have little performance impact, but makes the grammar
much cleaner.
* Fix EDN work to pass tests with correct numeric precedence.
* Update some dependencies.
* Update rusqlite to 0.12.
* Update error-chain to a forked version that implements Sync.
* Fix some compiler warnings.
* Remove unused imports in tests.
* Parse errors no longer naturally print with the expected symbol.
* Pre: unused import in translate.rs.
* Part 2: take a dependency on rusqlite for query arguments.
* Part 1: flatten V2 schema into V1. Add UUID and URI.
Bump expected ident and bootstrap datom count in tests.
* Part 5: parse edn::Value::Uuid.
* Part 3: extend ValueType and TypedValue to include Uuid.
* Part 4: add Uuid to query arguments.
* Part 6: extend db to support Uuid.
* Part 8: add a tx-parser test for #f NaN and #uuid.
* Part 7: parse and algebrize UUIDs in queries.
* Part 1: parse #inst in EDN and throughout query engine.
* Part 3: handle instants in db.
* Part 2: instants never matches integers in queries.
* Part 4: use DateTime for tx_instants.
* Add a test for adding and querying UUIDs and instants.
* Review comments.
* 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.
The parser mostly works and has a decent test suite. It parses all the
queries issued by the Tofino UAS, with some caveats. Known flaws:
* No support for tagged elements, comments, discarded elements or "'".
* Incomplete support for escaped characters in strings and the range of
characters that are allowed in keywords and symbols.
* Possible whitespace handling problems.
