22dad5d6ca [build] Include Gradle wrapper JAR in repository.
Presumably this was an error: `.gitignore` ignores all JAR files, but
this one really needs to be in version control.

6290cc9db2 Enforce partition integrity when setting its index r=nalexander
Timelines work starts to perform modifications on the partitions
that go beyond simple allocations. This change pre-emptively protects
partition integrity by asserting that index modifications are legal.

38a92229d7 Pre: Replace PartitionMapping trait with newtype. r=grisha
Generally, I think that Mentat is using too many small traits rather
than wrapping types into newtypes.  Wrapping into newtypes is cheap in
Rust, and it makes it easier to reason about the code.

Extract and improve test macros (#787) r=nalexander
* Part 1: Extract low-level test framework into mentat_db::debug for re-use.

* Part 2: Improve assert_matches!.

This corrects an incorrect pattern: a conversion method taking &self
but returning an owned value should be named like `to_FOO(&self) -> FOO`.  (A
reference-to-reference conversion should be named like `as_FOO(&self)
-> &FOO`.  A consuming conversion should be named like `into_FOO(self)
-> FOO`.)

In addition, this pushes the conversion via `to_edn` into the
`assert_matches!` macro, which lets consumers get a real data
structure (say, `Datoms`) and use it directly before or after
`assert_matches!`.  (Currently, consumers get back `edn::Value`
instances, which aren't nearly as pleasant to use as real data
structures.)

* Part 3: Use mentat_db::debug framework in Tolstoy crate.

The advantage of this approach is that compiling Tolstoy (or anything
that's not db, really) can be quite a bit faster than compiling db.

46f7db36c9 Small improvements accumulated while building the logins API on top of Mentat. (#779) r=grisha
These build on #778, and implement a variety of small fixes (related
parts are labelled as such), and one non-trivial part -- matching
tuple results with the `BindingTuple` trait. In practice, this is very
helpful, and greatly streamlined the logins API.

2cb7d441dc Part 2: Make it easier to match tuple results.
Right now, we write code like
```rust
match q_once(q, inputs)?.into_tuple()? {
    Some(vs) => match (vs.len(), vs.get(0), vs.get(1)) {
        (2, &Some(Binding::Scalar(TypedValue::Long(a))), &Some(Binding::Scalar(TypedValue::Instant(ref b)))) => Some((a, b.clone())),
        _ => panic!(),
    },
    None => None,
}
```
to length-check tuples coming out of the database.  It can also lead
to a lot of cloning because references are the easiest thing to hand.

This commit allows to write code like
```rust
match q_once(q, inputs)?.into_tuple()? {
    Some((Binding::Scalar(TypedValue::Long(a)), Binding::Scalar(TypedValue::Instant(b)))) => Some((a, b)),
    Some(_) => panic!(),
    None => None,
}
```
which is generally much easier to reason about.

2ab481f83e Part 2: Expose time related things at top-level.
Perhaps we actually want to subdivide the top-level namespace so that
there is a `mentat::time` module, but I'd prefer to make part of the
process of fixing the public API as we get ready to christen version
1.0.

1c0602fa00 Part 1: Add {From,To}Millis.
I think this is just oversight.  Generally, we should anticipate what
our consumers need to do to interact with Mentat, and producing milli-
and micro-second timestamps is part of that need.

b9f3681728 Part 2: Allow to Deref StructuredMap to the underlying IndexMap.
Again, this is a fundamental Rust pattern for newtypes.  It's awfully

d49f702512 Part 1: Expand Binding::val() into Binding::{into_*,as_*}.

99deb87b9f Build Entity instances, not Term* instances. Fixes #674. (#778) r=grisha 2018-07-05 16:42:02 -07:00
Nick Alexander
eb1df31ac4 Part 7: Improve TermBuilder interface; expose lookup refs and tx functions.
These are functions on `TermBuilder` itself to prevent mixing mutable
and immutable references in the most natural style.  That is,
```
builder.add(e, a, builder.lookup_ref(...))
```
fails because `add` borrows `builder` mutably and `lookup_ref` borrows
`builder` immutably.  There's nothing here that requires a specific
builder (since we're not interning lookup refs on the builder, like we
are tempids) so we don't need an instance.

06056a8468 Part 6: Lift TxReport to core crate.
The `core` create didn't exist when the `db` was started, but this
type is clearly part of the public interface of Mentat.

Nick Alexander
1cb1847aa6 Part 5: Make existing TermBuilder actually build Entity instances.
There are a few tricky details to call out here.  The first is the
`TransactableValueMarker` trait.  This is strictly a marker (like
`Sized`, for example) to give some control over what types can be used
as value types in `Entity` instances.  This expression is needed due
to the network of `Into` and `From` relations between the parts of
valid `Entity` instances.  This allows to drop the `IntoThing`
work-around trait and use the established patterns.  (Observe that
`KnownEntid` makes this a little harder, due to the cross-crate
consistency restrictions.)

The second is that we can get rid `{add,retract}_kw`, since the
network of relations expresses the coercions directly.

The third is that this commit doesn't change the name `TermBuilder`,
even though it is now building `Entity` instances.  This is because
there's _already_ an `EntityBuilder` which fixes the `EntityPlace`.
It's not clear whether the existing entity building interface should
be removed or whether both should be renamed.  That can be follow-up.

Nick Alexander
76507623ac Part 4: Prepare EDN Entity type for interning tempids during parsing.
This is all part of moving the entity builder away from building term
instances and toward building entity instances.  One of the nice
things that the existing term interface does is allow consumers to use
lightweight reference counted tempid handles; I don't want to lose
that, so we'll build it into the entity data structures directly.

106d6fae11 Part 3: Implement Deref and DerefMut for InternSet.
This pattern is generally how newtype wrappers (like `struct
Foo(Bar)`) are implemented in Rust.

Nick Alexander
02a163a10f Part 2: Use ValueRc in InternSet.
We haven't observed performance issues using `Arc` instead of `Rc`,
and we want to be able to include things that are interned (including,
soon, `TempId` instances) in errors coming out of the
transactor.  (And `Rc` isn't `Sync`, so it can't be included in errors
directly.)

Nick Alexander
87f850a44e Part 1: Move intern_set into edn crate.
It's not great to keep lifting functionality higher and higher up the
crate hierarchy, but we really do want to intern while we parse.
Eventually, I expect that we will split the `edn` crate into `types`
and `parsing`, and the `types` crate can depend on a more efficient
interning dependency.

d82c7f8ef2 Cull unused mentat_parser_utils crate.
With the transition toward parsing with `rust-peg` and away from
`combine`, we're not using some of the many helpers we built to
support our unusual `combine` usage.  They can just go!

5fe4f12d32 Use concrete Mentat error types rather than failure::Error. (#769) r=grisha
In the language of
868273409c/book/src/error-errorkind.md
Mentat is a mid-level API, not an application, and therefore we should
prefer our own error types.  Writing an initial consumer of Mentat (a
Rust logins API targeting Mozilla Lockbox), I have found this to be
true: my consumer wants to consume concrete Mentat error types.

This doesn't go "all the way" and convert all sub-crates to the
Error/ErrorKind, but it does go part of the way.

ae427849d5 Expose sub-crate *Error types at top-level.
We're not exposing a uniform API with `mentat::Result` yet, meaning
that early consumers (e.g., the logins work for Mozilla Lockbox) need
to wrap errors from all over the Mentat crate hierarchy.
2018-06-27 15:05:43 -07:00
Nick Alexander
d31ec28aa8 Patch it all together: use MentatError at top-level.
I elected to keep Tolstoy using `failure::Error`, because Tolstoy
looks rather more like a high-level application (and will continue to
do so for a while) than a production-ready mid- or low-level API.
