Bumps github.com/ethereum/go-ethereum from 1.9.12 to 1.9.15.

Release notes

Sourced from github.com/ethereum/go-ethereum's releases.

Dextro Heat Sink (v1.9.15)

Geth v1.9.15 is a maintenance release containing bug fixes as well as implementations of all EIPs currently scheduled for the upcoming Berlin fork. A temporary test network for these EIPs has also been launched at https://yolonet.xyz/ and can be joined via Geth with --yolov1 flag.

The minimum Go version required to build go-ethereum is now Go 1.13.

Improvements and fixes in this release:

• The LES 'server pool' was rewritten and can now use DNS discovery to find light servers (#20758).
• Argument checking for natively-implemented console functions is improved (#21081, #21160).
• Geth no longer hangs during shutdown while waiting for synced blocks to import (#21114).
• The RPC client now sends WebSocket ping frames when connection is idle (#21142).
• Uses of the gosigar library have been replaced by gopsutil. This restores building Geth on darwin without cgo and makes automatic database cache size selection work on OpenBSD (#21041).
• Prometheus metrics exporting no longer sends duplicate type definitions (#21068).
• Password input prompts in Clef now work when stdin is not a TTY (#20960).
• Internal sync error reporting has been made more detailed (#21067).
• EVM JUMPDEST checks are a bit faster in certain cases (#21123).
• Fix the puppeth faucet's tweet retrieval endpoint (#21172).

The following core EIPs are implemented in this release:

• EIP-2537: Precompile for BLS12-381 curve operations (#21018).
• EIP-2315: JUMPSUB for the EVM (#20619).

Please note that the EIP implementations are not yet scheduled to activate and will receive further testing and development before the fork.

For a full rundown of the changes please consult the Geth 1.9.15 release milestone.

• Docker images published under ethereum/client-go.
• Ubuntu packages in our Launchpad PPA repository.
• OSX packages in our Homebrew Tap repository.

Pink Marble (v1.9.14)

Geth v1.9.14 is a regular maintenance release, but is also packs a punch with some interesting new features!

Ethereum mainnet currently contains over 700M transactions. Each full node maintains a search index, stating that transactions with hash H is stored in block B. This allows you to look up an arbitrary transaction from the past (at a significant storage cost). But how often do you look up transactions from years ago?

Geth v1.9.14 ships a --txlookuplimit flag, which specifies the number of recent blocks you want to maintain the search index for (by default it's 0 = since genesis). At its most extreme, you can set it to 1, to prune all past indexes. At the time of release, this reduces your LevelDB SSD footprint by 32GB! You can modify this flag at will, Geth will unindex/reindex in the background based on the current setting. If you unindex a lot of transactions, you might need to compact your database to reclaim the space immediately via debug.chaindbCompact().

Deleting transaction indexes locally is fine since they are not used in consensus nor in synchronization, so network health is unaffected. Light servers for now do need to maintain the full index since light clients rely on them. Huge props to @rjl493456442 and @holiman for this work (#20302).

In the current release, we've reworked gas estimation so that reverting transactions will give you a proper error, bubbling up the EVM revert reason (#20830). The release also renamed most of the RPC API related flags to make them consistent with our namespace style, but don't worry, the deprecated flags will keep working for the foreseeable future (#20935).

I see that you haven't updated any CHANGELOG files. Would it make sense to do so?

[samsondav]

Does anybody know was there some specific reason we didn't upgrade geth before?

[se3000]

IIRC there are some breaking API changes with geth in the last version.

[se3000]

One of the downsides of upgrading past our current version of go-ethereum is that it seems to add some noise at the begining of all of our test runs:

# gopkg.in/olebedev/go-duktape.v3
In file included from _cgo_export.c:4:
debugger.go:22:13: warning: unused function '_duk_debugger_attach' [-Wunused-function]

[se3000]

The breaking change appears to have come in this PR ethereum/go-ethereum#20895, where the function selector becomes an attribute instead of a method.

[JasonCoombs]

# gopkg.in/olebedev/go-duktape.v3
In file included from _cgo_export.c:4:
debugger.go:22:13: warning: unused function '_duk_debugger_attach' [-Wunused-function]

still noisy. will somebody be updating olebedev/go-duktape.v3 to remove _duk_debugger_attach or is it a required function that is only referenced at run-time when the debugger attaches?
