# General notes about the code:
|
2018-12-04 18:45:30 +00:00
|
|
|
# * Weird styling - the sections taken from the spec use python styling while
|
|
|
|
|
# the others use NEP-1 - helps grepping identifiers in spec
|
2020-11-04 21:52:47 +00:00
|
|
|
# * When updating the code, add TODO sections to mark where there are clear
|
|
|
|
|
# improvements to be made - other than that, keep things similar to spec unless
|
|
|
|
|
# motivated by security or performance considerations

performance fixes (#2259)
* performance fixes
* don't mark tree cache as dirty on read-only List accesses
* store only blob in memory for keys and signatures, parse blob lazily
* compare public keys by blob instead of parsing / converting to raw
* compare Eth2Digest using non-constant-time comparison
* avoid some unnecessary validator copying
This branch will in particular speed up deposit processing which has
been slowing down block replay.

# Performance notes:
|
|
|
|
|
# * The state transition is used in two contexts: to verify that incoming blocks
|
|
|
|
|
# are correct and to replay existing blocks from database. Incoming blocks
|
|
|
|
|
# are processed one-by-one while replay happens multiple blocks at a time.
|
|
|
|
|
# * Although signature verification is the slowest operation in the state
|
|
|
|
|
# state transition, we skip it during replay - this is also when we repeatedly
|
|
|
|
|
# call the state transition, making the non-signature part of the code
|
|
|
|
|
# important from a performance point of view.
|
|
|
|
|
# * It's important to start with a prefilled cache - generating the shuffled
|
|
|
|
|
# list of active validators is generally very slow.
|
|
|
|
|
# * Throughout, the code is affected by inefficient for loop codegen, meaning
|
|
|
|
|
# that we have to iterate over indices and pick out the value manually:
|
|
|
|
|
# https://github.com/nim-lang/Nim/issues/14421
|
|
|
|
|
# * Throughout, we're affected by inefficient `let` borrowing, meaning we
|
|
|
|
|
# often have to take the address of a sequence item due to the above - look
|
|
|
|
|
# for `let ... = unsafeAddr sequence[idx]`
|
|
|
|
|
# * Throughout, we're affected by the overloading rules that prefer a `var`
|
|
|
|
|
# overload to a non-var overload - look for `asSeq()` - when the `var`
|
|
|
|
|
# overload is used, the hash tree cache is cleared, which, aside from being
|
|
|
|
|
# slow itself, causes additional processing to recalculate the merkle tree.

Implement split preset/config support (#2710)
* Implement split preset/config support
This is the initial bulk refactor to introduce runtime config values in
a number of places, somewhat replacing the existing mechanism of loading
network metadata.
It still needs more work, this is the initial refactor that introduces
runtime configuration in some of the places that need it.
The PR changes the way presets and constants work, to match the spec. In
particular, a "preset" now refers to the compile-time configuration
while a "cfg" or "RuntimeConfig" is the dynamic part.
A single binary can support either mainnet or minimal, but not both.
Support for other presets has been removed completely (can be readded,
in case there's need).
There's a number of outstanding tasks:
* `SECONDS_PER_SLOT` still needs fixing
* loading custom runtime configs needs redoing
* checking constants against YAML file
* yeerongpilly support
`build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG`
* load fork epoch from config
* fix fork digest sent in status
* nicer error string for request failures
* fix tools
* one more
* fixup
* fixup
* fixup
* use "standard" network definition folder in local testnet
Files are loaded from their standard locations, including genesis etc,
to conform to the format used in the `eth2-networks` repo.
* fix launch scripts, allow unknown config values
* fix base config of rest test
* cleanups
* bundle mainnet config using common loader
* fix spec links and names
* only include supported preset in binary
* drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml

Implement split preset/config support (#2710)
* Implement split preset/config support
This is the initial bulk refactor to introduce runtime config values in
a number of places, somewhat replacing the existing mechanism of loading
network metadata.
It still needs more work, this is the initial refactor that introduces
runtime configuration in some of the places that need it.
The PR changes the way presets and constants work, to match the spec. In
particular, a "preset" now refers to the compile-time configuration
while a "cfg" or "RuntimeConfig" is the dynamic part.
A single binary can support either mainnet or minimal, but not both.
Support for other presets has been removed completely (can be readded,
in case there's need).
There's a number of outstanding tasks:
* `SECONDS_PER_SLOT` still needs fixing
* loading custom runtime configs needs redoing
* checking constants against YAML file
* yeerongpilly support
`build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG`
* load fork epoch from config
* fix fork digest sent in status
* nicer error string for request failures
* fix tools
* one more
* fixup
* fixup
* fixup
* use "standard" network definition folder in local testnet
Files are loaded from their standard locations, including genesis etc,
to conform to the format used in the `eth2-networks` repo.
* fix launch scripts, allow unknown config values
* fix base config of rest test
* cleanups
* bundle mainnet config using common loader
* fix spec links and names
* only include supported preset in binary
* drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml

Implement split preset/config support (#2710)
* Implement split preset/config support
This is the initial bulk refactor to introduce runtime config values in
a number of places, somewhat replacing the existing mechanism of loading
network metadata.
It still needs more work, this is the initial refactor that introduces
runtime configuration in some of the places that need it.
The PR changes the way presets and constants work, to match the spec. In
particular, a "preset" now refers to the compile-time configuration
while a "cfg" or "RuntimeConfig" is the dynamic part.
A single binary can support either mainnet or minimal, but not both.
Support for other presets has been removed completely (can be readded,
in case there's need).
There's a number of outstanding tasks:
* `SECONDS_PER_SLOT` still needs fixing
* loading custom runtime configs needs redoing
* checking constants against YAML file
* yeerongpilly support
`build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG`
* load fork epoch from config
* fix fork digest sent in status
* nicer error string for request failures
* fix tools
* one more
* fixup
* fixup
* fixup
* use "standard" network definition folder in local testnet
Files are loaded from their standard locations, including genesis etc,
to conform to the format used in the `eth2-networks` repo.
* fix launch scripts, allow unknown config values
* fix base config of rest test
* cleanups
* bundle mainnet config using common loader
* fix spec links and names
* only include supported preset in binary
* drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml
