This PR implements a small subset of the OTP
etsinterface.The following
etsfunctions are supported:ets:new/2ets:insert/2ets:lookup/2ets:delete/2The following parameters to
ets:new/2are supported:is_named{keypos, I :: non_neg_integer()}private|protected|publicaccess typesOnly the
settable type is supported.This limited functionality allows users to define ETS tables and share term data between processes in a manner that is more efficient than using message passing with a process. The likely initial users of this feature will be the logging subsystem, as well as parts of the (forthcoming) application support, for storing application environment settings.
This PR provides a partial implementation of issue #887. Subsequent PRs can add additional features from this issue.
