XDG in the Docker images

🚨 This is a breaking change if you use our Docker images.

It moves the default data dir from /var/lib/erigon to /home/erigon/.local/share/erigon.

If you mount your data and use our own docker images, you need to change the mount point to avoid re-syncing!

If you already setup your data dir to a custom directory -- no action is required.

If you don't use our docker images -- no action is required.

Changelog

• fixes for EIP-1559 in pending transactions, eth_getTransactionByHash,

• fix for debug_traceTransaction #2433

• fixes for intrinsic gas in trace_ methods #2440

• fixup for eth_syncing on the block 0

• fixes for trace_call and trace_callMany methods

• Sokol support improvements

• Breaking change: Docker builds now follow XDG spec (data in /home/erigon/.local/share/erigon) #2437

London Hardfork & Ropsten Consensus Issue

Please upgrade your nodes to 2021.07.04 before London hardfork!
Recently uncovered consensus bug in geth, nethermind and erigon affects mainnet too!
This bug is fixed in this (2021.07.04) release.

If you want to repair your Ropsten nodes without resync

If you are on mainnet, no need to repair anything.

Follow these steps accurately:

• upgrade to 2021.07.04

• run your node with --bad.block 10679538 option

• wait patiently for the node to unwind, find proper peers and re-sync from the bad block. can take quite some time and might look like it is stuck on [4/18 Bodies] Wrote block bodies

• restart your node WITHOUT --bad.block option.

Pruning

New flag --prunereplaces --storage-mode.

--prune is an INVERSION of --storage-mode

Examples:

• --storage-mode=h => "keep history";
• --prune=h means "PRUNE history".
• if you using --storage-mode=ht the equivalent is --prune=rc

New flag docs:

• h - prune history (ChangeSets, HistoryIndices - used by historical state access)
• r - prune receipts (Receipts, Logs, LogTopicIndex, LogAddressIndex - used by eth_getLogs and similar RPC methods)
• t - prune transaction by it's hash index
• c - prune call traces (used by trace_* methods)

By default, --prune deletes data older than 90K blocks from the tip of the chain (aka, for if tip block is no. 12'000'000, only the data between 11'910'000-12'000'000 will be kept).

Thus could be overridden by --prune.<mode>.older flags.
E.g. --prune.h.older=1000000 keeps the last 1'000'000 historical entries.

--prune= (empty list) means no pruning (full archive mode).

Breaking change in Dockerfile - user is not Root anymore

Please see changes here: https://github.com/ledgerwatch/erigon/pull/2397/files

Changelog

• pruning! (see #2399)

• default docker-compose now can do RPCDaemon in local-mode in another container. PR #2392 (kudos to https://github.com/mariuspod for the fixup!)

• no annoying "peer not found" error

• a fixup for Ropsten consensus issue (see the PR here)

• fixes in trace_replayTransaction, trace_replayBlock

• broadcast local pooled transactions

• remove preimage recording

• batches in streamable RPC requests

• improvements for Sokol

Repairing receipts

Who are affected

• if you synced on 2021.06.04 or earlier, and upgraded the node to 2021.06.05 at some point.

Who are NOT affected

• if you are still on 2021.06.04

• if you synced your node on Erigon 2021.06.05 or later;

---

If you are affected, your receipts could be damaged.

We provide an utility to fix the receipts in the db:

make hack
./build/bin/hack --action scanReceipts --chaindata <datadir>/erigon/chaindata

Changelog

• --rpc.batch.concurrency flag

• receipts repairing utility

• sentry improvements

• fixups for debug_traceTransaction

• trace_call is about 2x faster

• fixup for transaction propagation with an external sentry

• enable private rpc endpoint by default, allowing hybrid mode for the roc daemon out of the box

• don't crash rpcdaemon on streamable WS (we don't support them still, but at least the app doesn't crash on them)
