In the case where a field with a foreign index opens before the
foreign index has opened (and is available as a reference in the
holder), push the field into a queue to have its foreign index
applied once all indexes have opened.
In the `Inspect` function in `server/grpc.go`, getting
the value of an `int` field with a foreign index to
an index with `Keys()`, we need to return the string
key value instead of the BSI int value for the field.
This commit also changes the method `Field.keys()` to be
exported as `Field.Keys()` so that it's accessible in
the server package.
This commit changes the order of FieldOption application so that
it's always set before field.Open() is called.
This was required because field.Open() now uses some of the values
from FieldOptions to determine if/when to use a particular
translateStore. For example, when FieldOptions.ForeignIndex is set,
the translateStore from the foreign index is retrieved during
field.Open().
I ran:
brew upgrade protobuf
GO111MODULE=off go get -u github.com/gogo/protobuf/protoc-gen-gofast
I'm not sure if everything is still going to work, but I'm excited to
find out!
This allows a BSI field to have an option indicating
that it is a foreign key to another index. If the foreign
index has column keys, then this field handles string values
by using the foreign index's translate store.
The lowest limitation I've seen on any filesystem we care about is 255
characters. 230 leaves enough space that an index or field could be
backed up and have a timestamp and file extension appended while
still allowing for much longer index and field names.
This PR adds a `StatusError` to the `pproto.RowResponse` type, which
allows a stream to pass an error on the stream (encoded into
the `RowResponse.StatusError`). This can be checked downstream
for matching `EOF` or `err != nil` and handled appropriately.
This is helpful mainly with the `RowResponse` reducers which run in
goroutines. Instead of trying to manage a separate channel of errors
from those goroutines, we just follow the grpc model and send the
error with the stream.
The check for field existence is not necessary; since we
add the `_id` field to every response then at the very
least that field will be returned.
This check was preventin a query like `select _id from ...`
from returning any results.
