thiolliere d743a8b71f Implement parameterisable modules (#1800)
* first implementation

* remove done comment

* origin done

* impl log for instance

* impl inherent for instance

* Fix wasm build + full example build

this requires parity codec implements codec for core::marker::PhantomData

* patch parity-codec link to github branch

* improve internal names and fix instance prefix

* Fix in macros

* add test modules for support

this allow to test for construct_runtime as well.

The reason to have put that in another crate is:
* if we put test in `tests/` dir of srml/support then decl_storage fails to get
  srml-support access because it believes it is inside srml-support
  crate and so derive access to `quote!{ crate }` but this is wrong
  (and I don't see any way to prevent that, and it only bother us so I
  don't think that matters that much)
* if we put test inside lib.rs then contruct_runtime cannot be used
  because it call some macros that are defined with macros
  (decl_outer_event and decl_outer_origin) and thus rustc complains.

* defaultinstance to its own struct to avoid errors

* enforce <T, I> for Event and Config, impl test

* add origin, log, inherent to test

* test more code generation

* basic storage test

* fix typo

* rename a few imports and field

* delete wip test in example and runtime

* change default prefix to make it backward compatible with test

* rename Instance to I and Instantiable to Instance

note: the name of generic parameter I is only enforce by decl_module!
and this could be rewritten

* doc

* clean old TODOs

* update parity-codec to 3.2

* update node impl version + builds

* fix warning

* fix unrelated grandpa test

Stanislav Tkach e60be1ad12 Migrate network, primitives and rpc to the 2018 edition (#1710) 2019-02-06 19:07:48 +01:00
Bastian Köcher 190393d476 Make API backwards compatible with CC (#1697)
* Rework how a runtime api calls into the runtime

Now we generate a default implementation for each api call that calls
a generated method `method_runtime_api_impl`. This newly generated
method is the one that will be implemented by the `impl_runtime_apis`
macro in the runtime for the client side.

Benjamin Kampmann 15ae7cfef6 Document more TODOs as tickets (#1418)
Went through the TODOs, removed a bunch, which are outdated or nothing more than a regular comment, documented a bunch more as actual tickets and made them FIXMEs and unified their structure (`FIXME #TICKETNO DESC` for local tickets, `FIXME: DESC LINK` for external tickets) for easier in-editor support. Further more remove unnecessary remarks and related old code that I noticed in that instance.

change block requires a justification.
