Add runtime log level control via gRPC admin service by masih · Pull Request #3062 · sei-protocol/sei-chain

masih · 2026-03-12T20:53:53Z

Add a way to view and change log levels on a running node without restarting it. A small gRPC admin server listens on localhost only and exposes three RPCs: SetLogLevel, GetLogLevel, and ListLoggers. It builds on seilog's existing support for per-logger and glob-based pattern matching.

Once enabled, you can control logging through the CLI; for example:

seid log level set "x/evm/*" debug           # glob pattern
seid log level set x/evm/state warn.         # exact logger
seid log level set "*" info                  # all loggers
seid log level get x/evm/state               # explicit logger
seid log level list                          # all loggers
seid log level list x/evm                    # filter by prefix

To enable it, add this to app.toml:

[admin_server]
admin_enabled = true
admin_address = "127.0.0.1:9095"

Note:

the feature is disabled by default,
the address must be a loopback address (127.0.0.1 or ::1); anything else is rejected to avoid security foot-guns
level changes are in-memory only and won't survive a restart.

This commit was inadvertently reverted by the squash-merge of #3039. Restores ReceiptStoreConfig in app.toml, readReceiptStoreConfig(), BackendTypeName(), receipt config tests, and init_test.go. Conflicts resolved: - app_config.go: kept both ReceiptStore (from #3035) and Admin (from #3062) - receipt_store.go: kept BackendTypeName but used #3050's slog convention - parquet_store_test.go: kept #3053's deterministic pruning test fix Made-with: Cursor

## Summary The squash-merge of #3039 (`feat(flatkv): add read-only LoadVersion for state sync`) inadvertently reverted changes from 5 previously-merged PRs. The `yiren/flatkv-readonly` branch had accumulated stale versions of files through merge-from-main commits, and when the final squash-merge landed, those stale versions overwrote the newer code on `main`. ### PRs reverted by #3039 and restored in this PR | PR | Title | Key changes lost | |---|---|---| | **#2810** | fix(giga): check whether txs follow Giga ordering | `firstCosmosSeen` tx ordering check, `len(evmEntries) > 0` / `len(v2Entries) > 0` guards in `ProcessTXsWithOCCGiga` | | **#3035** | Add receiptdb config option in app.toml | `ReceiptStoreConfig` in app.toml, `readReceiptStoreConfig()`, `BackendTypeName()`, receipt config tests | | **#3043** | Add config to enable lattice hash | `EnableLatticeHash` config, composite store lattice hash support | | **#3021** | Background Transaction Generation | `block.go`, `block_builder.go` for cryptosim benchmark | | **#3046** | Add console logger and fix memiavl config for benchmark | `BlocksPerCommit=1`, `SnapshotInterval=1000`, `SnapshotMinTimeInterval=60` | ### Conflict resolutions Since several PRs landed after #3039 (notably #3050 slog migration, #3053 flaky test fix, #3062 admin service), cherry-picks required manual conflict resolution: - **`app/app.go`** (#2810): Kept #2810's structural changes, used `logger.Error` (from #3050) instead of `ctx.Logger().Error` - **`cmd/seid/cmd/app_config.go`** (#3035): Kept both `ReceiptStore` (from #3035) and `Admin` (from #3062) - **`sei-db/ledger_db/receipt/receipt_store.go`** (#3035): Restored `BackendTypeName` but dropped logger param (superseded by #3050 slog) - **`sei-db/ledger_db/receipt/parquet_store_test.go`** (#3035): Kept #3053's deterministic pruning test fix - **`sei-db/state_db/sc/composite/store_test.go`** (#3043): Merged all three needed imports - **`sei-db/common/logger/logger.go`** (#3046): Kept deletion from #3050; `consoleLogger` is no longer needed with slog - **`sei-db/state_db/bench/wrappers/db_implementations.go`** (#3046): Kept #3050's no-logger-param API --------- Signed-off-by: Cody Littley <cody.littley@seinetwork.io> Co-authored-by: Cody Littley <56973212+cody-littley@users.noreply.github.com> Co-authored-by: Cody Littley <cody.littley@seinetwork.io>
