      Support Tracking Forks in Substrate Pallet (#409) · 45163a72
      Hernando Castano authored 
      

* Support multiple "best headers" from different forks

* Update the name of a test

* Add note about multiple scheduled changes

* Disallow multiple scheduled authority set changes

* Return multiple best headers from Runtime APIs

* Remove invalid test write-up

* Add some sketch-ups of test scenarios

* Clean up test scenarios

* Add module for testing forks

* Write headers to storage

* Add way to check expected outcome for header imports

* Add support for importing finality proofs

* Support importing headers which schedule changes

* Write out test scenario using new framework

* Map authority set changes across forks

Gets all the tests in the `forks` module passing

* Remove basic tests

These were used when working on the initial test helper

* Prevent multiple pending set changes on the same fork

* Remove old test which allowed imports past unfinalized header

* Ignore failing test (for now)

* Rewrite `if` comparison using `match` and `cmp`

Fixes Clippy warning: `comparison_chain`

* Add helper for writing test headers with default characteristics

* Fix test that checked authority set updates

* Make note about importing headers on different unfinalized fork

* Perform some cleanup on the fork module

* Fix Clippy complaints

* Provide list of unfinalized headers to Runtime APIs

* Add proofs to expect() calls

* Make tests the focus of the forks module

* Allow specific errors to be checked in fork tests

* Remove unused method

* Replace unreachable() statement with expect()

* Rename storage `unfinalized_headers() `to make its purpose more clear

* Update Runtime API name in relayer to match pallet

* Commit `unfinalized_headers` changes I forgot to add

* Rename ChainTipHeight to BestHeight

* Make schedule_next_set_change require a mutable reference

* Remove check for key when enacting authority set

We only expect to take the happy-path in the pallet anyways, so this check
to save ourselves the time spent decoding the entry isn't really used.

* Clear justification set when writing headers to storage

* Clarify why we only allow one set change per fork

* Change best_headers() to return HeaderIDs

Prevents us from returning full headers (which are more expensive to
get from storage) since we only care about header IDs (number, hash)
anyways.

* Fix Clippy complaint

* Make note about equivocations

* Use HeaderIds when returning incomplete headers

This change stops returning full headers which are more expensive
to get from storage than header Ids (number, hash) are. Clients likely
don't need the full header anyways which is why this change is fine.

* Introduce HeaderId type to reduce type complexity

* Add signal hash to storage during genesis config

* Return error instead of expect()-ing

* Fix Clippy lint about `ok_or` fn call

* Rename `forks` module to indicate that it's for testing

* Use `const` for `expect()` proofs

* Remove check that key exists before `kill`-ing value

      Integrate Grandpa Proof Checker into Substrate Pallet (#375) · 7662f2ff
      Hernando Castano authored 
      

* Remove the Substrate primitives crate

The types here were only used in one place, the pallet itself. If other
components start using these types we can considering moving them back
into a standalone crate.

* Start trying to integrate justification module

* Make Substrate blocks configurable in Pallet

* WIP: Try and generalize justification test helpers

* Fix tests which use "real" justifications

* Put common test helpers alongside mock code

* Use common helper for creating headers

* Remove usage of UintAuthorityId

This change favours the use of the Ed25519Keyring authorities
in order to keep things consistent with the tests.

* Add documentation around config trait types

* Make test header, hash, and number types consistent

* Update modules/substrate/src/verifier.rs

* Derive `RuntimeDebug` instead of `Debug`

* Add `Paramter` as a trait constraint on config types

Since we use these types as part of the dispatchable functions
we should explicitly require this.

* Enforce that hasher output matches expected hash type

* Accept headers over indexes when making test justifications

* Check that authority sets are valid

* Make Clippy happy

* Apply correct Clippy fix

* Move justification code into primitives module

* Use new module in verifier code

* Add primitives module for Substrate test helpers

* WIP

* Move justification generation into test_helpers

* Revert commits which move `justification` into primitives

This reverts commit 03a381f0

      Initial Substrate Header Chain Implementation (#296) · 7364e2fa
      Hernando Castano authored 
      * Add pallet template from Substrate Dev Hub

* Clean up un-needed stuff from template

* Sketch out dispatchable interface

* Introduce notion of finality chain

* Add dependencies which were removed during a rebase

* Sketch out idea for finality header-chain pallet

* Sketch out ChainVerifier trait

* Add storage parameter to verifier

* Write out some things I think I need for finality verification

* Add some pseudocode for marking finalized headers

* Remove parity_scale_codec duplicate

* Move verification logic into pallet

I've been struggling with getting the generic types between the storage and verifier
traits to play nice with each other. As a way to continue making progress I'm moving
everything to the pallet. This way I hope to make progress towards a functional
pallet.

* Start doing verification around authority set changes

* Remove commented BridgeStorage and ChainVerifier traits

* Create Substrate bridge primitives crate

* Add logic for updating scheduled authority sets

* Introduce notion of imported headers

* Implement basic header ancestry checker

* Add mock runtime for tests

* Add testing boilerplate

* Add some storage read/write sanity tests

* Add some basic header import tests

* Add tests for ancestry proofs

* Create helper for changing authority sets

* Fix authority set test

Fixes a problem with how the scheduled change was counted as well as
a SCALE encoding issue

* Correctly check for scheduled change digests

There's no guarantee that the consensus digest item will be the last
one in a header, which is how it was previously being checked.

Thanks to Andre for pointing me to the Grandpa code that does this.

* Mark imported headers as finalized when appropriate

When a header that finalizes a chain of headers is succesfully imported
we also want to mark its ancestors as finalized.

* Add helper for writing test headers

* Add test helper for scheduling authority set changes

* Bump Substrate pallet and primitives to rc6

* Remove Millau verifier implementation

* Add some doc comments

* Remove some needless returns

* Make Clippy happy

* Split block import from finalization

* Make tests compile again

* Add test for finalizing header after importing children

* Create a test stub for importing future justifications

* Start adding genesis config

* Reject justifications from future

We should only be accepting justifications for the header
which enacted the current authority set. Any ancestors of
that header which require a justification can be imported
but they must not be finalized.

* Add explanation to some `expect()` calls

* Start adding GenesisConfig

* Plug genesis config into runtime

* Remove tests module

* Check for overflow when updating authority sets

* Make verifier take ownership of headers during import

* Only store best finalized header hash

Removed the need to store the whole header, since we store
it was part of the ImportedHeaders structure anyways

* Add some helpers to ImportedHeader

* Update ancestry checker to work with ImportedHeaders

* Update ancestry tests to use ImportedHeaders

* Update import tests to use ImportedHeaders

* Clean up some of the test helpers

* Remove stray dbg!

* Add doc comments throughout

* Remove runtime related code

* Fix Clippy warnings

* Remove trait bound on ImportedHeader struct

* Simplify checks in GenesisConfig

* Rename `get_header_by_hash()`

* Alias `parity_scale_codec` to `codec`

* Reword Verifier documentation

* Missed codec rename in tests

* Split ImportError into FinalizationError

* Remove ChainVerifier trait

This trait was a remenant of the original design, and it is not required
at the moment. Something like it should be added back in the future to
ensure that other chains which conform to this interface can be used
by higher-level bridge applications.

* Fix the verifier tests so they compile

* Implement Deref for ImportedHeader

* Get rid of `new` methods for some Substrate primitives

* Ensure that a child header's number follows its parent's

* Prevent ancestry checker from aimlessly traversing to genesis

If an ancestor which was newer than the child header we were checking we
would walk all the way to genesis before realizing that we weren't related.
This commit fixes that.

* Remove redundant clones

* Ensure that old headers are not finalized

Prevents a panic where if the header being imported and `best_finalized`
were the same header the ancestry checker would return an empty list. We
had made an assumption that the list would always be populated, and if this
didn't hold we would end up panicking.

* Disallow imports at same height as `best_finalized`

* Fix Clippy warnings

* Make NextScheduledChange optional

* Rework how scheduled authority set changes are enacted

We now require a justification for headers which _enact_ changes
instead of those which _schedule_ changes. A few changes had to
be made to accomodate this, such as changing when we check for
scheduled change logs in incoming headers.

* Update documentation for Substrate Primitives

* Clarify why we skip header in requires_justification check

* Add description to assert! call

* Fix formatting within macros

* Remove unused dependencies from runtime

* Remove expect call in GenesisConfig

* Turn FinalityProof into a struct

* Add some inline TODOs for follow up PRs

* Remove test which enacted multiple changes

This should be added back at some later point in time, but right now
the code doesn't allow for this behaviour.

* Use `contains_key` when checking for header

This is better than using `get().is_some()` since we skip
decoding the storage value

* Use initial hash when updating best_finalized

* Add better checks around enacting scheduled changes

* Rename finality related functions

* Appease Clippy
