Previously, when block sync started, we immediately started filling up to 8192 blocks. Usually this is fine, blocks are small in the early numbers. The threshold then is lowered as we measure the size of the blocks that are filled. However, if the node is shut down and restarts syncing while we're in a heavy segment, that might be bad. This PR introduces a more conservative initial threshold of 2K blocks instead. --- eth/downloader/downloader.go | 4 ++-- eth/downloader/downloader_test.go | 24 ++++++++++++------------ eth/downloader/queue.go | 14 ++++++++------ eth/downloader/queue_test.go | 6 +++--- eth/downloader/testchain_test.go | 2 +- 5 files changed, 26 insertions(+), 24 deletions(-) diff --git a/eth/downloader/downloader.go b/eth/downloader/downloader.go index 95db0cced448..df033f157882 100644 --- a/eth/downloader/downloader.go +++ b/eth/downloader/downloader.go @@ -213,7 +213,7 @@ func New(stateDb ethdb.Database, mux *event.TypeMux, chain BlockChain, lightchai dl := &Downloader{ stateDB: stateDb, mux: mux, -

This also includes some unrelated changes improving the reliability of eth/fetcher tests, which fail a lot because they are time-dependent. --- eth/fetcher/fetcher.go | 18 ++++++++++-------- eth/fetcher/fetcher_test.go | 18 +++++++++++++++++- trie/sync_bloom.go | 34 +++++++++++++++++++--------------- 3 files changed, 46 insertions(+), 24 deletions(-) diff --git a/eth/fetcher/fetcher.go b/eth/fetcher/fetcher.go index 253f6f5cf5c2..c4aa795532db 100644 --- a/eth/fetcher/fetcher.go +++ b/eth/fetcher/fetcher.go @@ -753,15 +753,17 @@ func (f *Fetcher) insert(peer string, block *types.Block) { // internal state. func (f *Fetcher) forgetHash(hash common.Hash) { // Remove all pending announces and decrement DOS counters - for _, announce := range f.announced[hash] { - f.announces[announce.origin]-- - if f.announces[announce.origin] == 0 { - delete(f.announces, announce.origin) + if announceMap, ok := f.announced[hash]; ok { + for _, announce := range announceMap { + f.announces[announce.origin]-- + if f.announces[announce.origin] <= 0 { + delete(f.announces, announce.origin) + } + } + delete(f.announced, hash) + if f.announceChangeHook != nil { + f.announceChangeHook(hash, false) } - } - delete(f.announced, hash) - if f.announceChangeHook != nil { - f.announceChangeHook(hash, false) } // Remove any pending fetches and decrement the DOS counters if announce := f.fetching[hash]; announce != nil { diff --git a/eth/fetcher/fetcher_test.go b/eth/fetcher/fetcher_test.go index 2d319a554d37..978392800dc5 100644 --- a/eth/fetcher/fetcher_test.go +++ b/eth/fetcher/fetcher_test.go @@ -677,15 +677,30 @@ func testInvalidNumberAnnouncement(t *testing.T, protocol int) { badBodyFetcher := tester.makeBodyFetcher("bad", blocks, 0) imported := make(chan *types.Block) + announced := make(chan interface{}) tester.fetcher.signHook = func(block *types.Block) error { imported <- block return nil } // Announce a block with a bad number, check for immediate drop + tester.fetcher.announceChangeHook = func(hash common.Hash, b bool) { + announced <- nil + } tester.fetcher.Notify("bad", hashes[0], 2, time.Now().Add(-arriveTimeout), badHeaderFetcher, badBodyFetcher) + verifyAnnounce := func() { + for i := 0; i < 2; i++ { + select { + case <-announced: + continue + case <-time.After(1 * time.Second): + t.Fatal("announce timeout") + return + } + } + } + verifyAnnounce() verifyImportEvent(t, imported, false) - tester.lock.RLock() dropped := tester.drops["bad"] tester.lock.RUnlock() @@ -698,6 +713,7 @@ func testInvalidNumberAnnouncement(t *testing.T, protocol int) { goodBodyFetcher := tester.makeBodyFetcher("good", blocks, 0) // Make sure a good announcement passes without a drop tester.fetcher.Notify("good", hashes[0], 1, time.Now().Add(-arriveTimeout), goodHeaderFetcher, goodBodyFetcher) + verifyAnnounce() verifyImportEvent(t, imported, true) tester.lock.RLock() diff --git a/trie/sync_bloom.go b/trie/sync_bloom.go index 085b229e6d15..7901d53d5bca 100644 --- a/trie/sync_bloom.go +++ b/trie/sync_bloom.go @@ -45,11 +45,12 @@ var ( // provided disk database on creation in a background thread and will only start // returning live results once that's finished. type SyncBloom struct { - bloom *bloomfilter.Filter - inited uint32 - closer sync.Once - closed uint32 - pend sync.WaitGroup + bloom *bloomfilter.Filter + inited uint32 + closer sync.Once + closed uint32 + pend sync.WaitGroup + closeCh chan struct{} } // NewSyncBloom creates a new bloom filter of the given size (in megabytes) and @@ -64,7 +65,8 @@ func NewSyncBloom(memory uint64, database ethdb.Iteratee) *SyncBloom { // Assemble the fast sync bloom and init it from previous sessions b := &SyncBloom{ - bloom: bloom, + bloom: bloom, + closeCh: make(chan struct{}), } b.pend.Add(2) go func() { @@ -125,16 +127,17 @@ func (b *SyncBloom) init(database ethdb.Iteratee) { // meter periodically recalculates the false positive error rate of the bloom // filter and reports it in a metric. func (b *SyncBloom) meter() { + // check every second + tick := time.NewTicker(1 * time.Second) + defer tick.Stop() + for { - // Report the current error ration.

The idea for this change is for all TryXXX functions, the error is already returned and we don't need to fire a log explicitly. Recently there are a few tickets #25613 #25589 reporting that the trie nodes are missing because of debug.SetHead. The root cause is after resetting, the chain rewinds to a historical point and re-imports the blocks on top. Since the node is already synced and started to accept transactions previously, these transactions are still kept in the txpool and verified by txpool with a live state. This live state is constructed based on the live trie database, which is changed fast by node referencing and de-referencing. Unfortunately, when we construct a live state(like the state in txpool), we don't reference the state we have. The blockchain will garbage collect the intermediate version nodes in another thread which leads the broken live state. The best solution for this is to forcibly obtain a reference for all live states we create and call release function once it's used up. But it might end up with more junks persisted into disk. Will try to find an elegant solution later in the following PR. --- trie/secure_trie.go | 85 +++++++++++++++++++++------------------------ 1 file changed, 39 insertions(+), 46 deletions(-) diff --git a/trie/secure_trie.go b/trie/secure_trie.go index d87bbb3e2a47..936243efa697 100644 --- a/trie/secure_trie.go +++ b/trie/secure_trie.go @@ -35,14 +35,14 @@ func NewSecure(owner common.Hash, root common.Hash, db *Database) (*SecureTrie, return NewStateTrie(owner, root, db) } -// StateTrie wraps a trie with key hashing.

Instead of the schema type, a string is used to distinguish between hashbased/pathbased db accessors. This also moves some code from trie package to rawdb package.

After the introduction of the TryAccount* functions, TryGet, TryUpdate and TryDelete are now only meant to read an account's storage. In their current form, they assume that an account storage is stored in a separate trie, and that the hashing of the slot is independent of its account's address. The proposed structure for a stateless storage breaks these two assumptions: the hashing of a slot key requires the address and all slots and accounts are stored in a single trie. This PR therefore adds an address parameter to the interface. It is ignored in the MPT version, so this change has no functional impact, however it will reduce the diff size when merging verkle trees. --- core/state/database.go | 20 ++++++++++---------- core/state/state_object.go | 6 +++--- trie/secure_trie.go | 12 ++++++------ 3 files changed, 19 insertions(+), 19 deletions(-) diff --git a/core/state/database.go b/core/state/database.go index 729dd502bbb2..c4362754d5b7 100644 --- a/core/state/database.go +++ b/core/state/database.go @@ -68,10 +68,10 @@ type Trie interface { // TODO(fjl): remove this when StateTrie is removed GetKey([]byte) []byte - // TryGet returns the value for key stored in the trie.
