      Introduce inherent digests (#2466) · 6e253c89
      DemiMarie-parity authored
      
      
      * Introduce inherent digests
      
      * Implement inherent digests
      
      * fix silly error
      
      * Implementation of inherent digests in BABE
      
      All tests pass. There are still limitations:
      
      1. The runtime strips out inherent digests, so BABE must re-add them.
      2. The test runtime checks that it can re-compute all digests.  It
         can’t, so I had to comment out that test.
      
      * Fix compilation and seal import
      
      Seals were not imported correctly: the pre-digest was imported twice,
      instead of both it and the seal being imported.  Also, other parts of
      the code did not compile due to incomplete refactoring.
      
      * Remove bogus assertion
      
      * Fix testsuite compilation
      
      * Remove unused import
      
      * Fix compiler diagnostics
      
      * Add inherent digest parameters to block constructors
      
      This enforces that inherent digests are added first.
      
      * Fixup Cargo.lock
      
      * Fix build errors
      
      * Re-add an incorrectly removed import
      
      * Bump primitive-types version
      
      * Update Cargo.lock
      
      * Refactoring
      
      * Use inherent digests for AuRa
      
      They do reach the runtime, but get stripped.  I have not figured out
      where.
      
      * Fix compilation errors
      
      * Fix compilation errors due to incorrect types
      
      * Fix whitespace
      
      Suggested-by: default avatarTomasz Drwiega <[email protected]>
      
      * Add preamble
      
      Suggested-by: default avatarTomasz Drwiega <[email protected]>
      
      * Fix silly compile error
      
      * Refactor pre-digest finding code into a separate function
      
      * Remove unwanted assertion
      
      It is too likely to bring down the entire blockchain.
      
      Suggested-by: default avatarTomasz Drwiega <[email protected]>
      
      * Use `find_pre_digest` after runtime, too
      
      Also, use `Member` trait rather than rolling our own requirements.
      
      Suggested-by: default avatarTomasz Drwiega <[email protected]>
      
      * Fix various warnings
      
      mostly due to upgrading the dependency on `error_chain`.
      
      * Pre-digests nearly complete
      
      This nearly completes the implementation of pre-runtime digests.
      
      * `Seal2` → `Seal` and fix test suite
      
      * Try to fix the storage error
      
      * Try to fix storage (again)
      
      * Fix tests
      
      * Hopefully finish pre-runtime digests
      
      The key is to pass *only* the pre-runtime digests to the runtime.  The
      others must be stripped out by `initialize_block`.
      
      * Fix silly typo
      
      * Fix another silly mistake
      
      * Remove unnecessary filtering of BABE pre-digests
      
      We no longer get duplicate BABE pre-digests, so if they appear, the
      header should be rejected outright.
      
      * Update Cargo.lock files
      
      * Reformatting
      
      * Fix silly typo in inherent digest code
      
      Also, revert `error.rs` files that contained calls to the `error_chain!`
      macro.
      
      * Try to keep the runtime from stripping pre-digests
      
      Currently runs into the “Storage root must match that calculated”
      assertion.
      
      * Don’t compute storage root until storage changes are done.
      
      Also, fix a compilation error.
      
      * Fix compile-time error
      
      * Fix compilation errors
      
      * Fix more compile errors
      
      * Hopefully it compiles this time…
      
      * Fix compilation and add docs
      
      * Prevent BABE from adding duplicate pre-runtime digests
      
      Found by comparing with the AuRa code.  I also did some refactoring.
      
      * Respond to review and fix some warnings
      
      * Delete some dead code introduced earlier
      
      * More dead code goes away
      
      * `ref mut` → `&mut`
      
      * Respond to review and fix some warnings
      
      * Fix compilation error
      
      * Remove unneeded `HashT` type parameter
      
      Suggested-by: default avatarRobert Habermeier <[email protected]>
      
      * Remove spurious #[allow(deprecated)]
      
      * Document inherent digest parameter to `build_block`
      
      * Delete `Simple` trait
      
      It wasn’t needed
      
      * delete wrongly added files
      
      * Fix trait bounds
      
      * Digest serialization tests
      
      I also did some reformatting and cleanup.
      
      * Apply suggestions from code review
      
      Reformatting
      
      Co-Authored-By: default avatarAndré Silva <[email protected]>
      
      * Swap two arguments to `propose` and `propose_with`
      
      Also, remove some needless unsafe code.
      
      * Remove bogus `#![allow(deprecated)]` annotations
      
      With the removal of the deprecated `Seal` variant, these are not needed.
      
      * Add a missing `#[allow(deprecated)]` in the AuRa tests
      
      * Fix silly compile error
      
      * Fix silly compiler error
      
      RLS did not tell me that I hadn’t fixed `babe/lib.rs`, so I missed it.
      
      * Fixes made automatically by Cargo
