# This file contains helpers for dealing with forks - we have two ways we can
# deal with forks:
# * generics - this means using the static typing and differentiating forks
# at compile time - this is preferred in fork-specific code where the fork
# is known up-front, for example spec functions.
# * variants - this means using a variant object and determining the fork at
# runtime - this carries the obvious risk and complexity of dealing with
# runtime checking, but is of course needed for external data that may be
# of any fork kind.
#
# For generics, we define `Forky*` type classes that cover "similar" objects
# across forks - for variants, they're called `Forked*` instead.
# See withXxx and `init` for convenient ways of moving between these two worlds.
# A clever programmer would use templates, macros and dark magic to create all
# these types and converters :)

Store finalized block roots in database (3s startup) (#3320) * Store finalized block roots in database (3s startup) When the chain has finalized a checkpoint, the history from that point onwards becomes linear - this is exploited in `.era` files to allow constant-time by-slot lookups. In the database, we can do the same by storing finalized block roots in a simple sparse table indexed by slot, bringing the two representations closer to each other in terms of conceptual layout and performance. Doing so has a number of interesting effects: * mainnet startup time is improved 3-5x (3s on my laptop) * the _first_ startup might take slightly longer as the new index is being built - ~10s on the same laptop * we no longer rely on the beacon block summaries to load the full dag - this is a lot faster because we no longer have to look up each block by parent root * a collateral benefit is that we no longer need to load the full summaries table into memory - we get the RSS benefits of #3164 without the CPU hit. Other random stuff: * simplify forky block generics * fix withManyWrites multiple evaluation * fix validator key cache not being updated properly in chaindag read-only mode * drop pre-altair summaries from `kvstore` * recreate missing summaries from altair+ blocks as well (in case database has lost some to an involuntary restart) * print database startup timings in chaindag load log * avoid allocating superfluos state at startup * use a recursive sql query to load the summaries of the unfinalized blocks

Support for driving multiple EL nodes from a single Nimbus BN (#4465) * Support for driving multiple EL nodes from a single Nimbus BN Full list of changes: * Eth1Monitor has been renamed to ELManager to match its current responsibilities better. * The ELManager is no longer optional in the code (it won't have a nil value under any circumstances). * The support for subscribing for headers was removed as it only worked with WebSockets and contributed significant complexity while bringing only a very minor advantage. * The `--web3-url` parameter has been deprecated in favor of a new `--el` parameter. The new parameter has a reasonable default value and supports specifying a different JWT for each connection. Each connection can also be configured with a different set of responsibilities (e.g. download deposits, validate blocks and/or produce blocks). On the command-line, these properties can be configured through URL properties stored in the #anchor part of the URL. In TOML files, they come with a very natural syntax (althrough the URL scheme is also supported). * The previously scattered EL-related state and logic is now moved to `eth1_monitor.nim` (this module will be renamed to `el_manager.nim` in a follow-up commit). State is assigned properly either to the `ELManager` or the to individual `ELConnection` objects where appropriate. The ELManager executes all Engine API requests against all attached EL nodes, in parallel. It compares their results and if there is a disagreement regarding the validity of a certain payload, this is detected and the beacon node is protected from publishing a block with a potential execution layer consensus bug in it. The BN provides metrics per EL node for the number of successful or failed requests for each type Engine API requests. If an EL node goes offline and connectivity is resoted later, we report the problem and the remedy in edge-triggered fashion. * More progress towards implementing Deneb block production in the VC and comparing the value of blocks produced by the EL and the builder API. * Adds a Makefile target for the zhejiang testnet
