Previously the search key was never modified but each node kept information how to slice and compare it in keyOffset. Now the keyOffset is not needed as this information is included in the slice of the search key. This way the keyOffset can be removed and key manipulation simplified. --- trie/stacktrie.go | 72 +++++++++++++++++++++-------------------------- 1 file changed, 32 insertions(+), 40 deletions(-) diff --git a/trie/stacktrie.go b/trie/stacktrie.go index f9ff10b62d..76258c3112 100644 --- a/trie/stacktrie.go +++ b/trie/stacktrie.go @@ -54,12 +54,11 @@ func returnToPool(st *StackTrie) { // in order.

17:50:58 +0100 Subject: [PATCH 035/194] core, eth: improve delivery speed on header requests (#23105) This PR reduces the amount of work we do when answering header queries, e.g. when a peer is syncing from us. For some items, e.g block bodies, when we read the rlp-data from database, we plug it directly into the response package. We didn't do that for headers, but instead read headers-rlp, decode to types.Header, and re-encode to rlp. This PR changes that to keep it in RLP-form as much as possible. When a node is syncing from us, it typically requests 192 contiguous headers. On master it has the following effect: - For headers not in ancient: 2 db lookups. One for translating hash->number (even though the request is by number), and another for reading by hash (this latter one is sometimes cached). - For headers in ancient: 1 file lookup/syscall for translating hash->number (even though the request is by number), and another for reading the header itself. After this, it also performes a hashing of the header, to ensure that the hash is what it expected. In this PR, I instead move the logic for "give me a sequence of blocks" into the lower layers, where the database can determine how and what to read from leveldb and/or ancients. There are basically four types of requests; three of them are improved this way. The fourth, by hash going backwards, is more tricky to optimize. However, since we know that the gap is 0, we can look up by the parentHash, and stlil shave off all the number->hash lookups. The gapped collection can be optimized similarly, as a follow-up, at least in three out of four cases.

Using string keys with context is discouraged because they may clash with keys created by other packages.

It turns out that leveldb batch memory allocation is super inefficient. The main reason is the allocation step of leveldb Batch is too small when the batch size is large. It can take a few second to build a leveldb batch with 100MB size. Luckily, leveldb also offers another API called MakeBatch which can pre-allocate the memory area. So if the approximate size of batch is known in advance, this API can be used in this case. It's needed in new state scheme PR which needs to commit a batch of trie nodes in a single batch. Implement the feature in a seperate PR. --- core/rawdb/table.go | 5 +++++ ethdb/batch.go | 3 +++ ethdb/leveldb/leveldb.go | 8 ++++++++ ethdb/memorydb/memorydb.go | 7 +++++++ tests/fuzzers/bn256/bn256_fuzz.go | 1 + tests/fuzzers/stacktrie/trie_fuzzer.go | 1 + trie/iterator_test.go | 4 ++++ trie/trie_test.go | 1 + 8 files changed, 30 insertions(+) diff --git a/core/rawdb/table.go b/core/rawdb/table.go index 91fc31b660..bd47161c5f 100644 --- a/core/rawdb/table.go +++ b/core/rawdb/table.go @@ -172,6 +172,11 @@ func (t *table) NewBatch() ethdb.Batch { return &tableBatch{t.db.NewBatch(), t.prefix} } +// NewBatchWithSize creates a write-only database batch with pre-allocated buffer. +func (t *table) NewBatchWithSize(size int) ethdb.Batch { + return &tableBatch{t.db.NewBatchWithSize(size), t.prefix} +} + // tableBatch is a wrapper around a database batch that prefixes each key access // with a pre-configured string. type tableBatch struct { diff --git a/ethdb/batch.go b/ethdb/batch.go index 1353693318..541f40c838 100644 --- a/ethdb/batch.go +++ b/ethdb/batch.go @@ -43,6 +43,9 @@ type Batcher interface { // NewBatch creates a write-only database that buffers changes to its host db // until a final write is called.

The generated methods will behave identically to the reflect-based encoder, but run faster because there is no reflection overhead. Package rlp now provides the EncoderBuffer type for incremental encoding. This is used by generated code, but the new methods can also be useful for hand-written encoders. There is also experimental support for generating DecodeRLP, and some new methods have been added to the existing Stream type to support this. Creating decoders with rlpgen is not recommended at this time because the generated methods create very poor error reporting. More detail about package rlp changes: * rlp: externalize struct field processing / validation This adds a new package, rlp/internal/rlpstruct, in preparation for the RLP encoder generator. I think the struct field rules are subtle enough to warrant extracting this into their own package, even though it means that a bunch of adapter code is needed for converting to/from rlpstruct.Type. * rlp: add more decoder methods (for rlpgen) This adds new methods on rlp.Stream: - Uint64, Uint32, Uint16, Uint8, BigInt - ReadBytes for decoding into []byte - MoreDataInList - useful for optional list elements * rlp: expose encoder buffer (for rlpgen) This exposes the internal encoder buffer type for use in EncodeRLP implementations. The new EncoderBuffer type is a sort-of 'opaque handle' for a pointer to encBuffer. It is implemented this way to ensure the global encBuffer pool is handled correctly. --- go.mod | 1 + go.sum | 2 + rlp/decode.go | 180 +++++-- rlp/decode_test.go | 43 +- rlp/encbuffer.go | 352 +++++++++++++ rlp/encbuffer_example_test.go | 45 ++ rlp/encode.go | 368 +++----------- rlp/encode_test.go | 3 +- rlp/encoder_example_test.go | 10 +- rlp/internal/rlpstruct/rlpstruct.go | 213 ++++++++ rlp/rlpgen/gen.go | 735 +++++++++++++++++++++++++++ rlp/rlpgen/gen_test.go | 92 ++++ rlp/rlpgen/main.go | 148 ++++++ rlp/rlpgen/testdata/bigint.in.txt | 10 + rlp/rlpgen/testdata/bigint.out.txt | 49 ++ rlp/rlpgen/testdata/nil.in.txt | 30 ++ rlp/rlpgen/testdata/nil.out.txt | 289 +++++++++++ rlp/rlpgen/testdata/optional.in.txt | 17 + rlp/rlpgen/testdata/optional.out.txt | 153 ++++++ rlp/rlpgen/testdata/rawvalue.in.txt | 11 + rlp/rlpgen/testdata/rawvalue.out.txt | 64 +++ rlp/rlpgen/testdata/uints.in.txt | 10 + rlp/rlpgen/testdata/uints.out.txt | 53 ++ rlp/rlpgen/types.go | 98 ++++ rlp/typecache.go | 199 +++----- 25 files changed, 2701 insertions(+), 474 deletions(-) create mode 100644 rlp/encbuffer.go create mode 100644 rlp/encbuffer_example_test.go create mode 100644 rlp/internal/rlpstruct/rlpstruct.go create mode 100644 rlp/rlpgen/gen.go create mode 100644 rlp/rlpgen/gen_test.go create mode 100644 rlp/rlpgen/main.go create mode 100644 rlp/rlpgen/testdata/bigint.in.txt create mode 100644 rlp/rlpgen/testdata/bigint.out.txt create mode 100644 rlp/rlpgen/testdata/nil.in.txt create mode 100644 rlp/rlpgen/testdata/nil.out.txt create mode 100644 rlp/rlpgen/testdata/optional.in.txt create mode 100644 rlp/rlpgen/testdata/optional.out.txt create mode 100644 rlp/rlpgen/testdata/rawvalue.in.txt create mode 100644 rlp/rlpgen/testdata/rawvalue.out.txt create mode 100644 rlp/rlpgen/testdata/uints.in.txt create mode 100644 rlp/rlpgen/testdata/uints.out.txt create mode 100644 rlp/rlpgen/types.go diff --git a/go.mod b/go.mod index f7d0f6bdad..9d46bb1d6f 100644 --- a/go.mod +++ b/go.mod @@ -67,6 +67,7 @@ require ( golang.org/x/sys v0.0.0-20210816183151-1e6c022a8912 golang.org/x/text v0.3.6 golang.org/x/time v0.0.0-20210220033141-f8bda1e9f3ba + golang.org/x/tools v0.1.0 gopkg.in/natefinch/npipe.v2 v2.0.0-20160621034901-c1b8fa8bdcce gopkg.in/olebedev/go-duktape.v3 v3.0.0-20200619000410-60c24ae608a6 gopkg.in/urfave/cli.v1 v1.20.0 diff --git a/go.sum b/go.sum index 53cee50ab3..06a4cabc39 100644 --- a/go.sum +++ b/go.sum @@ -460,6 +460,7 @@ golang.org/x/mod v0.0.0-20190513183733-4bf6d317e70e/go.mod h1:mXi4GBBbnImb6dmsKG golang.org/x/mod v0.1.0/go.mod h1:0QHyrYULN0/3qlju5TqG8bIK38QM8yzMo5ekMj3DlcY= golang.org/x/mod v0.1.1-0.20191105210325-c90efee705ee/go.mod h1:QqPTAvyqsEbceGzBzNggFXnrqF1CaUcvgkdR5Ot7KZg= golang.org/x/mod v0.3.0/go.mod h1:s0Qsj1ACt9ePp/hMypM3fl4fZqREWJwdYDEqhRiZZUA= +golang.org/x/mod v0.4.2 h1:Gz96sIWK3OalVv/I/qNygP42zyoKp3xptRVCWRFEBvo= golang.org/x/mod v0.4.2/go.mod h1:s0Qsj1ACt9ePp/hMypM3fl4fZqREWJwdYDEqhRiZZUA= golang.org/x/net v0.0.0-20180724234803-3673e40ba225/go.mod h1:mL1N/T3taQHkDXs73rZJwtUhF3w3ftmwwsq0BUmARs4= golang.org/x/net v0.0.0-20180826012351-8a410e7b638d/go.mod h1:mL1N/T3taQHkDXs73rZJwtUhF3w3ftmwwsq0BUmARs4= @@ -580,6 +581,7 @@ golang.org/x/tools v0.0.0-20191125144606-a911d9008d1f/go.mod h1:b+2E5dAYhXwXZwtn golang.org/x/tools v0.0.0-20191216173652-a0e659d51361/go.mod h1:TB2adYChydJhpapKDTa4BR/hXlZSLoq2Wpct/0txZ28= golang.org/x/tools v0.0.0-20191227053925-7b8e75db28f4/go.mod h1:TB2adYChydJhpapKDTa4BR/hXlZSLoq2Wpct/0txZ28= golang.org/x/tools v0.0.0-20200108203644-89082a384178/go.mod h1:TB2adYChydJhpapKDTa4BR/hXlZSLoq2Wpct/0txZ28= +golang.org/x/tools v0.1.0 h1:po9/4sTYwZU9lPhi1tOrb4hCv3qrhiQ77LZfGa2OjwY= golang.org/x/tools v0.1.0/go.mod h1:xkSsbof2nBLbhDlRMhhhyNLN/zl3eTqcnHD5viDpcZ0= golang.org/x/xerrors v0.0.0-20190717185122-a985d3407aa7/go.mod h1:I/5z698sn9Ka8TeJc9MKroUUfqBBauWjQqLJ2OPfmY0= golang.org/x/xerrors v0.0.0-20191011141410-1b5146add898/go.mod h1:I/5z698sn9Ka8TeJc9MKroUUfqBBauWjQqLJ2OPfmY0= diff --git a/rlp/decode.go b/rlp/decode.go index 5f2e5ad5fe..9214dbfb37 100644 --- a/rlp/decode.go +++ b/rlp/decode.go @@ -27,6 +27,8 @@ import ( "reflect" "strings" "sync" + + "github.com/ethereum/go-ethereum/rlp/internal/rlpstruct" ) //lint:ignore ST1012 EOL is not an error. @@ -148,7 +150,7 @@ var ( bigInt = reflect.TypeOf(big.Int{}) ) -func makeDecoder(typ reflect.Type, tags tags) (dec decoder, err error) { +func makeDecoder(typ reflect.Type, tags rlpstruct.Tags) (dec decoder, err error) { kind := typ.Kind() switch { case typ == rawValueType: @@ -220,55 +222,20 @@ func decodeBigIntNoPtr(s *Stream, val reflect.Value) error { } func decodeBigInt(s *Stream, val reflect.Value) error { -

charset=UTF-8 Content-Transfer-Encoding: 8bit This change makes use of the new code generator rlp/rlpgen to improve the performance of RLP encoding for Header and StateAccount. It also speeds up encoding of ReceiptForStorage using the new rlp.EncoderBuffer API. The change is much less transparent than I wanted it to be, because Header and StateAccount now have an EncodeRLP method defined with pointer receiver. It used to be possible to encode non-pointer values of these types, but the new method prevents that and attempting to encode unadressable values (even if part of another value) will return an error. The error can be surprising and may pop up in places that previously didn't expect any errors. To make things work, I also needed to update all code paths (mostly in unit tests) that lead to encoding of non-pointer values, and pass a pointer instead.

The speedup is achieved by avoiding reflection overhead during node encoding. The interface type trie.node now contains a method 'encode' that works with rlp.EncoderBuffer. Management of EncoderBuffers is left to calling code. trie.hasher, which is pooled to avoid allocations, now maintains an EncoderBuffer. This means memory resources related to trie node encoding are tied to the hasher pool.
