It seems there is no fully typed library implementation of an LRU cache.
So I wrote one. Method names are the same as github.com/hashicorp/golang-lru,
and the new type can be used as a drop-in replacement.
Two reasons to do this:
- It's much easier to understand what a cache is for when the types are right there.
- Performance: the new implementation is slightly faster and performs zero memory
allocations in Add when the cache is at capacity. Overall, memory usage of the cache
is much reduced because keys are values are no longer wrapped in interface.
When the interpreter is configured to use extra-eips, this change makes it so that all the opcodes are deep-copied, to prevent accidental modification of the 'base' jumptable.
Closes: #26136

This PR changes geth to read the eip1559 params from the chain config instead of the globals.
This way the parameters may be changed by forking the chain config code, without creating a large diff throughout the past and future usages of the parameters.

This PR ports a few changes from PBSS:
- Fix the snapshot generator waiter in case the generation is not even initialized
- Refactor db inspector for ancient store
This PR fixes a regression causing snapshots not to be generated in "geth --import" mode. It also fixes the geth export command to be truly readonly, and adds a new test for geth export.
This adds a
* core/vm, tests: optimized modexp + fuzzer
* common/math: modexp optimizations
* core/vm: special case base 1 in big modexp
* core/vm: disable fastexp
This changes the error message for mismatching chain ID to show
the given and expected value. Callers expecting this error must be
changed to use errors.Is.
* ethclient/gethclient: improve time-sensitive flaky test
* eth/catalyst: fix (?) flaky test
* core: stop blockchains in tests after use
* core: fix dangling blockchain instances
* core: rm whitespace
* eth/gasprice, eth/tracers, consensus/clique: stop dangling blockchains in tests
* all: address review concerns
* core: goimports
* eth/catalyst: fix another time-sensitive test
* consensus/clique: add snapshot test run function
* core: rename stop() to stopWithoutSaving()

This PR reworks tx indexer a bit. Compared to the original version, one scenario is no longer handled - upgrading from legacy geth without indexer support.
The tx indexer was introduced in 2020 and have been present through hardforks, so it can be assumed that all Geth nodes have tx indexer already. So we can simplify the tx indexer logic a bit:
- If the tail flag is not present, it means node is just initialized may or may not with an ancient store attached. In this case all blocks are regarded as unindexed
- If the tail flag is present, it means blocks below tail are unindexed, blocks above tail are indexed
This change also address some weird cornercases that could make the indexer not work after a crash.
`geth dumpgenesis` currently does not respect the content of the data directory. Instead, it outputs the genesis block created by command-line flags. This PR fixes it to read the genesis from the database, if the database already exists.

This PR cleans up the configurations for pruner and snapshotter by passing a config struct.
And also, this PR disables the snapshot background generation if the chain is opened in "read-only" mode. The read-only mode is necessary in some cases. For example, we have a list of commands to open the etheruem node in "read-only" mode, like export-chain. In these cases, the snapshot background generation is non expected and should be banned explicitly.
core/blockchain: downgrade tx indexing and unindexing logs from info to debug
If a user has a finite tx lookup limit, they will see an "unindexing" info level log each time a block is imported. This information might help a user understand that they are removing the index each block and some txs may not be retrievable by hash, but overall it is generally more of a nuisance than a benefit. This change downgrades the log to a debug log.
This shortens the chain config summary in bad block reports,
and adds go-ethereum version information as well.

This changes the CI / release builds to use the latest Go version. It also
upgrades golangci-lint to a newer version compatible with Go 1.19.
In Go 1.19, godoc has gained official support for links and lists. The
syntax for code blocks in doc comments has changed and now requires a
leading tab character. gofmt adapts comments to the new syntax
automatically, so there are a lot of comment re-formatting changes in this
PR. We need to apply the new format in order to pass the CI lint stage with
Go 1.19.
With the linter upgrade, I have decided to disable 'gosec' - it produces
too many false-positive warnings. The 'deadcode' and 'varcheck' linters
have also been removed because golangci-lint warns about them being
unmaintained. 'unused' provides similar coverage and we already have it
enabled, so we don't lose much with this change.
This PR makes the event-sending for deleted and new logs happen in batches, to prevent OOM situation due to large reorgs.
