The PQL looks like:
```
Range(frame=f, field0 >< [200,610])
```
One thing I noticed while implementing this is that it doesn't seem
like `FieldRange()` is used in either `Frame` or `View`; the Executor
calls `Fragment.FieldRange()` directly. The problem with this is that
the offset logic is calculated in the Frame, but since the Executor
doesn't go through Frame, then the Executor also has to calculate
the offset before calling `Fragment.FieldRange`. We should unify this
logic somewhere. Note, this applies to both `FieldRange` and
`FieldRangeBetween`.
Turning off IPv6 causes the tests to fail because the Go
`net.Listen()` function obtains a `[::]` address when using
a `localhost:0` bind address. Looking through the Go source
code, I don't see a good way to fix that.
This change adds a test flag to allow users to specify the
network name when running the test:
```sh
go test github.com/pilosa/pilosa/server -network tcp4
```
A configurable limit has been added to restrict the number of
mutating calls in a `pql.Query`. This is to prevents requests from
timing out from large queries.
The default is set to 5000 writes per request and is configurable
through the configuration file and the command line flags.
this affects the scanner/parser and makes it produce signed ints rather than
uints, and so it affects all code that is expecting unsighed ints to come out of
the parser.
Consolidates all the pql.Call implementations into a single
pql.Call struct. This is needed to support user-defined schemas
on frames.
This also has the added benefit that a lot of redundant parsing
code has been consolidated.
This commit changes the `pql.Query` so that it can accept one or more
top-level calls instead of only one.
The query request format change because a query with a single call is
still valid. However, the result format now returns a `results` field
that has one result for each top-level call. The `profiles` field is
still the same, however, it combines all profiles from all bitmap
responses into one return so that there's not duplicate attributes.
