2592506288 Implement parsing of simple :find expressions. (#196) r=nalexander
* Test the mentat_query directory on Travis.

* Export common types from edn.

This allows you to write

  use edn::{PlainSymbol,Keyword};

instead of

  use edn:🔣:{PlainSymbol,Keyword};

* Add an edn::Value::is_keyword predicate.

* Clean up query, preparing for query-parser.

* Make EDN keywords and symbols take Into<String> arguments.

* Implement parsing of simple :find lists.

* Rustfmt query-parser. Split find and query.

* Review comment: values_to_variables now returns a NotAVariableError on failure.

* Review comment: rename gimme to to_parsed_value.

* Review comment: add comments.

8e16bee201 Pass existing idents to datoms->schema-fragment, allowing the 'upgrade' of an existing ident to an attribute. 2016-12-16 10:25:17 -08:00
Richard Newman
103a86f440 Add a :none migration for schema management. Fixes #113. r=grisha
This allows for code to run before and after a schema fragment is
added for the first time.

The anticipated use for this is twofold:

1. To do initial setup, e.g., defining global entities.
2. To 'adopt' unmanaged attributes already defined in the store.

This 'pre' would manually alter or retract attributes so that the
transact of the new schema datoms can complete.

For example, if properties :foo/bar and :foo/baz will be unchanged,
but :noo/zob needs to change from a string to an integer, the :none
pre-function can alter the ident, and the :none post-function can
migrate and clean up.

3212be565c Allow callers to run functions within the scope of a transaction.
This generalizes the transactor loop to allow callers to run
an arbitrary function within an `in-transaction!` body.

Combined with exposing `<report-transact-tx-data!`, this allows
an admittedly sophisticated consumer to conditionally query and
transact in a consistent way -- for example, cleaning up inconsistent
data then transacting a new schema version.

9d361055d3 Implement schema alteration. Fixes #78.
Altering uniqueness and cardinality attributes works, with the exception
of enabling uniqueness from nothing.

:db/noHistory and :db/isComponent changes are implemented but untested,
and aren't really supported by Datomish anyway.

39c909ec32 Rewrite resolve-id-literals to use bulk <avs. (#88)
The metaphor we use is that of "evolution", where each "evolutionary
step" contains a number of different "generations".  Entities in the
process of being resolved are increasingly "evolved" into simpler
generations, until no further evolution is possible.

1c83287fcf Pre: Make <avs handle fulltext datoms correctly.
The test would fail because we would have an [a v] pair with a string
value, but we were looking for the fulltext rowid in <avs.  Using
all_datoms correctly looks up the string value, at the cost of crippling
the speed of <avs.

60c7db4301 Pre: Make testing consistent by sorting fulltext values before inserting.
This sorts fulltext values inserted in a single transaction, not across
transactions.  This makes the rowids assigned in the fulltext_values
table internally consistent, even as the order of entities and datoms
changes (as the transaction applying algorithm evolves over time).  The
test changes simply make the fulltext values sort easily.

In theory, these fulltext values could be very large, and sorting might
be very expensive.  In practice, we expect values to differ in their
first few characters, so that this is efficient (i.e., proportional to
the number of fulltext values inserted and not their size).
