* Expose priv validators for use in testing
* Generalize block header validation test past height 1
* Remove ineffectual assignment
* Remove redundant SaveState call
* Reorder comment for clarity
* Use the block executor ApplyBlock function instead of implementing a stripped-down version of it
* Remove commented-out code
* Remove unnecessary test
The required tests already appear to be implemented (implicitly) through
the TestValidateBlockHeader test.
* Allow for catching of specific error types during TestValidateBlockCommit
* Make return error testable
* Clean up and add TestValidateBlockCommit code
* Fix formatting
* Extract function to create a new mock test app
* Update comment for clarity
* Fix comment
* Add skeleton code for evidence-related test
* Allow for addressing priv val by address
* Generalize test beyond a single validator
* Generalize TestValidateBlockEvidence past first height
* Reorder code to clearly separate tests and utility code
* Use a common constant for stop height for testing in state/validation_test.go
* Refactor errors to resemble existing conventions
* Fix formatting
* Extract common helper functions
Having the tests littered with helper functions makes them less easily
readable imho, so I've pulled them out into a separate file. This also
makes it easier to see what helper functions are available during
testing, so we minimize the chance of duplication when writing new
tests.
* Remove unused parameter
* Remove unused parameters
* Add field keys
* Remove unused height constant
* Fix typo
* Fix incorrect return error
* Add field keys
* Use separate package for tests
This refactors all of the state package's tests into a state_test
package, so as to keep any usage of the state package's internal methods
explicit.
Any internal methods/constants used by tests are now explicitly exported
in state/export_test.go
* Refactor: extract helper function to make, validate, execute and commit a block
* Rename state function to makeState
* Remove redundant constant for number of validators
* Refactor mock evidence registration into TestMain
* Remove extraneous nVals variable
* Replace function-level TODOs with file-level TODO and explanation
* Remove extraneous comment
* Fix linting issues brought up by GolangCI (pulled in from latest merge from develop)
What happened:
New code was supposed to fall back to last height changed when/if it
failed to find validators at checkpoint height (to make release
non-breaking).
But because we did not check if validator set is empty, the fall back
logic was never executed => resulting in LoadValidators returning an
empty validator set for cases where `lastStoredHeight` is checkpoint
height (i.e. almost all heights if the application does not change
validator set often).
How it was found:
one of our users - @sunboshan reported a bug here
https://github.com/tendermint/tendermint/pull/3537#issuecomment-482711833
* use last height changed in validator set is empty
* add a changelog entry
* rpc: store validator info periodly
* increase ValidatorSetStoreInterval
also
- unexpose it
- add a comment
- refactor code
- add a benchmark, which shows that 100000 results in ~ 100ms to get 100
validators
* make the change non-breaking
* expand comment
* rename valSetStoreInterval to valSetCheckpointInterval
* change the panic msg
* add a test and changelog entry
* update changelog entry
* update changelog entry
* add a link to PR
* fix test
* Update CHANGELOG_PENDING.md
