The core package uses global variables that keep from having
more than one Tile38 instance runnning in the same process.
Move the core variables in the server.Options type which are
uniquely stated per Server instance.
The build variables are still present in the core package.
Each MATCH is inclusive OR, thus
WITHIN fleet MATCH train* truck* BOUNDS 33 -112 34 -113
will find all trains and trucks that within the provides bounds.
This commit fixes an issue where Tile38 will fail to start
because the AOF file contains a partially written command, which
is caused by the server not having enough disk space to complete
the previous write.
This was discovered and reported by a Theresa D on the Tile38
Slack channel.
This commit fixes an issue where the server may start up without
a "server_id" assigned, which in turn will cause a follower to
be unable to connect.
This issues is caused by including a pre-generated "data/config"
file that does not include the "server_id" field.
This commit allows for buffering any GeoJSON object.
For example:
INTERSECTS fleet BUFFER 1000 OBJECT {...LineString...}
This will buffer add a 1 kilometer buffer to a linesting and
search the 'fleet' collection for all objects that
intersect the buffered linestring.
This commit also allows for performing INTERSECTS with a POINT
type. Thus allowing for a polygon-over-point operation, which is
an inverted point-in-polygon.
This commit accepts incoming connections even before the AOF
dataset has been loaded into memory. Though only a very limited
command set is allowed.
Allowed commands:
PING, ECHO, OUTPUT, QUIT
All other commands will return:
LOADING Tile38 is loading the dataset in memory
This is useful for establishing connections for the purpose of
checking process and network state.
This issues fixes an issue where a search command with a where
clause using the "z" field would not match correctly for point
that where contained inside a GeoJSON Feature type.
Tile38 now extracts the Z coordinate from Point and Feature/Point
types.
