v0.3.0

Changed

CLI

• Breaking Flag shorthand -p for --plaintext has been re-assigned to Substreams params definition, to align with substreams run/gui on that aspect. There is no shorthand anymore for --plaintext.

  If you were using before -p, please convert to --plaintext.

  Note We expect that this is affecting very few users as --plaintext is usually used only on developers machine.

Library

• gRPC InvalidArgument error(s) are not retried anymore like specifying and invalid start block or argument in your request.

• Breaking ReadManifestAndModule signature changed to add params []string, this is required for proper computation of module's output hash, upgrade by passing nil for this parameter.

• Breaking ReadManifestAndModuleAndBlockRange signature changed to add params []string, this is required for proper computation of module's output hash, upgrade by passing nil for this parameter.

Added

• Added support for --params, -p (can be repeated multiple times) on the form -p <module>=<value>.

• Added logging of new Session received values (linear_handoff_block, max_parallel_workers and resolved_start_block).

• Added --header, -H (can be repeated multiple times) flag to pass extra headers to the server.

• Added ClientConfig on sink.Sinker instance to retrieve Substreams client configuration easily.

• Added ReadManifestAndModuleAndBlockRange as a convenience for ReadManifestAndModule and ReadBlockRange.

• Added ReadBlockRange so that it's possible to easily read a block range argument against a Substreams parsed module.

Fixed

• The stop_block for infinite streaming passed to the server is now 0, it seems MaxUint64 was causing some issues on the server, should result normally in better startup performance now.
