* don't kill the program if not connected to a bootstrap node within 30 seconds
* recover faster from loss of network connectivity
* connectWorker(): sleep 1s between dials
* launch_local_testnet.sh: increase BOOTSTRAP_TIMEOUT
* don't use metric value in program logic
* refactor some ungainly variable names
* cache beacon committee size calculation
this fixes a bug in get_validator_churn_limit as well
* fix
* make committee counts consistently uint64
mixing feels like the worst of the two worlds
- delete "tests/simulation/{data,validators}" by default, because old
validator keys can lead to a crash with a cryptic error message
- actually start the Prometheus daemon on `make eth2_network_simulation`
- kill any running Prometheus daemon on exit
- fix some shell script syntax incompatible with Bash
* remove cruft
* reenable fork choice and fix several issues
* in addForkChoice_v2, the `.error` field would be accessed even when
Result is ok
* remove workaround for invalid block structure in fork choice
* fix `tmpState` being used recursively in callback, causing state
corruption while processing attestation
* fix block callback being called twice per block
* pass state to callback to avoid unnecessary rewinding
* enable head select, fix another bug
* never use `get` without `isOk`
* log nil blockref in case blockref is nil
* add missing error checking
* use correct epoch when updating attestation message
When clearing blocks, a callback is called - this callback, if it uses
`tmpState`, will be corrupted because it's not fully up to date when the
callback is called - we thus introduce a specific state cache for this
purpose - ideally, it can be removed later when epoch caching is
improved.
Incidentally, this helps block sync speed a lot - without this state,
the block sync would ping-pong between attestation state and block state
which is costly.
hash_tree_root was turning up when running beacon_node, turns out to be
repeated hash_tree_root invocations - this pr brings them back down to
normal.
this PR caches the root of a block in the SignedBeaconBlock object -
this has the potential downside that even invalid blocks will be hashed
(as part of deserialization) - later, one could imagine delaying this
until checks have passed
there's also some cleanup of the `cat=` logs which were applied randomly
and haphazardly, and to a large degree are duplicated by other
information in the log statements - in particular, topics fulfill the
same role
* restore EpochRef and flush statecaches on epoch transitions
* more targeted cache invalidation
* remove get_empty_per_epoch_cache(); implement simpler but still faster get_beacon_proposer_index()/compute_proposer_index() approach; add some abstraction layer for accessing the shuffled validator indices cache
* reduce integer type conversions
* remove most of rest of integer type conversion in compute_proposer_index()
This also assigns precise types to the constants in the minimal
and mainnet presets in order to reduce the chance of compilation
errors when custom presets are used (previously, only the custom
presets have precisely assigned types for the constants).
* quick workaround for epochref cache issue
* disable assertion which doesn't work without epochref caches
* get local testnets and altona running again
htr is fast now, so hitting the database to load the state root is no
longer motivated - the more simple code is less vulnerable to database
corruption.
