      Clean up PersistedValidationData (#2353) · d4fdbf7d
      Sergey Pepyakin authored 
      * PVD: `block_number`->`relay_parent_number`

* ValidationParams: `relay_chain_height`->`relay_parent_number`

* Expose DMQ MQC hash as a well-known-key

This way the relay storage merkle proofs will be able to obtain the DMQ
MQC hash and we will be able to remove the it from the
PersistedValidationData struct.

* PersistedValidationData: Remove HRMP MQC heads

* PersistedValidationData: Remove `dmq_mqc_head`

* Expose the HRMP ingress channel index as a well-known-key

This way a parachain (PVF and collator) can find all the parachains that
have an outbound channel to the given one. That allows in turn to find
all the inbound channels for the given para.

Having access to that allows the parachain to get the same information
as the hrmp_mqc_heads now provide.

* Rename `relay_storage_root` to `relay_parent_storage_root`

      Add warning when dropping inclusion inherent (#2261) · 089ba85c
      Peter Goodspeed-Niklaus authored 
      * Add warning when dropping inclusion inherent

* improve warning when dropping inclusion inherent

- use the actual runtime `warn!` macro
- do not speculate about why the error occurred
- show the actual error returned

* BROKEN: add note if the current block matches the session start block

This doesn't compile for a variety of reasons; this commit demonstrates
what the issues are. I don't think this is an essential feature, so I'm
stopping work on it here instead of pushing through it.

* Revert "BROKEN: add note if the current block matches the session start block"

This reverts commit eeb79ab7708ec94224fa60c9e1a46e12c18d52fd.

* ensure a runtime logger exists before attempting to log a warning to it

      HRMP channel deposits (#2225) · c644c39f
      Sergey Pepyakin authored 
      * Drive by fixes

The visibility modifiers are remnants of the previous structure where
HRMP wasn't a standalone module, by rather a submodule of the router
module.

* Add Currency assoc type to Config

This would allow us to reserve balance for deposits. This commit also
integrates the HRMP module in rococo, test-runtime and mocks to use the
balances pallet.

* Fix a bug that doesn't increment the age

In case the request is not confirmed, the age would be incremented but
not persisted.

* Fix cleaning the indexes

Before that change, the cleaning of the channel indexes was wrong, because it
naively removed entire rows that was pertaining to the para we delete.
This approach is flawed because it doesn't account for the rows that are
pertaining to other paras that contain the outgoing one.

This clearly violates the invariant imposed on the indexes, that all
the index rows must contain alive paras, but apart from that it also
lead to the situation where ingress index would contain the a different
set of channels that an egress have.

* Reserve currency for opening the channels

Note the ugly `unique_saturated_into` calls. The reason for them is the
currency trait accepts and defines the `Balance` associated type and the
deposit values are coming from the `HostConfiguration` where they are
defined using the `Balance`.

I figured that parameterising `HostConfiguration` would be annoying. On
the other hand, I don't expect these `unique_saturated_into` calls to
give us problems since it seems to be a reasonable assumption that this
module will be instantiated within a runtime where the Currency provided
will have a Balance that matches the one used in the configuration.

* Tests: Adapt `run_to_block` so that it submits a proper config

* Tests: exercise the deposit logic

      Reduce the inclusion inherent's actual weight if the block is already heavy (#2060) · fcc0fca1
      Peter Goodspeed-Niklaus authored 
      

* don't modify inherent data on heavy block

* write up current thinking on block weight detection

* extract inherent inclusion check into its own function

* put heavy block check into runtime

* the `inclusion` inherent call is Operational, not Mandatory

This resolves a lot of the trickiness about this issue, because
we no longer need to override or supplant any existing proposer
logic; the existing logic should exhibit these behaviors:

- the `inclusion` inherent is prioritized over standard transactions
- but if it's too heavy, i.e. in case of runtime upgrade, it'll be
  dropped in favor of that.

It is my belief that allowing the proposer to just not include
this data won't have any adverse effects: it's equivalent to replacing
them with empty versions of themselves, which the `ProvideInherent`
impl already does.

* Revert "the `inclusion` inherent call is Operational, not Mandatory"

This reverts commit e58858d109b18b84e7af3ac47981c6900b2d9a3e.

* Revert "write up current thinking on block weight detection"

This reverts commit fd587b80c46761b2a2b62448193348237863f99f.

* Revert "don't modify inherent data on heavy block"

This reverts commit 38299d3c23e9efb5a354d8cfa658e62a5c8c7ddf.

* add backed candidate block weight assumption to configuration

* Limit backed candidates according to a candidate weight heuristic.

This approach replaces making the inclusion inherent non-mandatory.
It's still not ideal in that we have to configure a heuristic for
how much each backed candidate 'weighs', instead of directly
measuring it somehow.

This approach also never truncates the signed bitfields. The
rationale for that depends on some assumptions:

- processing the signed bitfields is cheap compared to the
  backed candidates
- it is beneficial to the progress of the relay chain
  to update the signed bitfields even if not all backed candidates
  are updated

* simplify limit_backed_candidates and weight assumption

* don't trust the provisioner to fairly distribute candidates

* use saturating subtraction

* empty commit to restart ci

* use new mechanism for getting max block weight

* apply weight refunds to the inclusion inherent

This makes some assumptions about fundamental weights, which are
encapsulated as constants. From there, it lets Substrate know
what the actual computed weight of the inherent is.

* use a correct fixed weight for the inclusion inherent

Co-authored-by: default avatarGuillaume Thiolliere <[email protected]>

* use dynamic inclusion weight so we reduce calculated weight when excluding candidates

* don't double-count this intrinsic's weight in the block weight

* add unit tests of fn limit_backed_candidates

* add tests that the inclusion inherent's weight correctly updates

      Add relay storage root to persisted validation data (#2161) · a864eaa0
      Sergey Pepyakin authored 
      * Cont.: Implement the state root obtaining during inclusion

During inclusion now we obtain the storage root by passing it through
the inclusion_inherent.

* Fix tests

* Bump rococo spec version

* Reorder the parent header into the end

of the inclusion inherent.

When the parent header is in the beginning, it shifts the other two
fields, so that a previous version won't be able to decode that. If
we put the parent header in the end, the other two fields will stay
at their positions, thus make it possible to decode with the previous
version.

That allows us to perform upgrade of rococo runtime without needing of
simultanuous upgrade of nodes and runtime, or restart of the network.

* Squash a stray tab

      Do not use rely on the block initialization when calling runtime APIs (#2123) · 4405f52e
      Sergey Pepyakin authored 
      

* Don't initialize block when calling runtime APIs

* Adapt check_validation_outputs

We split the code path for the inclusion and for the commitments checking.

* Slap #[skip_initialize_block] on safe runtime APIs

That is, those that should not be affected by this attribute

* Make `Scheduled` not ephemeral

So that it is persisted in the storage and ready to be inspected
by the runtime APIs. This is in contrast to what was before, where we
would remove the storage entry and then rely on the scheduling performed
by `on_initialize` again.

* Add a big fat comment

* Typos

Co-authored-by: default avatarRobert Habermeier <[email protected]>

* Move session change to the end of the current block

Previously, it was the beginning of the next block. This allows us to
put #[skip_initialize_block]

* Update tests

* Fix a test in paras registrar

Also refactor it a bit so the next time there are more chances this kind
of issue is diagnosed quicker.

* Add for_runtime_api to inclusion's check_validation_outputs
