1. Purpose or design rationale of this PR

ev.Txsmight include transactions that we cannot include in a block for some reason. Double check that block is not empty before committing to it.

2. PR title

Your PR title must follow conventional commits (as we are doing squash merge for each PR), so it must start with one of the following types:

  • build: Changes that affect the build system or external dependencies (example scopes: yarn, eslint, typescript)
  • ci: Changes to our CI configuration files and scripts (example scopes: vercel, github, cypress)
  • docs: Documentation-only changes
  • feat: A new feature
  • fix: A bug fix
  • perf: A code change that improves performance
  • refactor: A code change that doesn't fix a bug, or add a feature, or improves performance
  • style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
  • test: Adding missing tests or correcting existing tests

3. Deployment tag versioning

Has the version in params/version.go been updated?

* refactor: eliminate double re-execution in AsyncChecker (#1036)

* fix: make reorg mode explicit (#1049)

* fix: avoid committing empty blocks after the deadline (#1051)

* fix: initialize pending block with an empty block (#1052)

* fix: reuse timestamp for blocks failing CCC (#1031)

we assume that same height wont trigger multiple reorgs to be able
to put an upper bound on the reorg depth. We rely on the fact that
AsyncChecker executes transactions one-by-one and tells worker the
safe set of transactions to include in the replacement block that
wont trigger another error on the same block. If worker changes the
timestamp and that causes significant changes to the execution flow
of included transactions; we might have a height where multiple
reorgs happen.
