From 70b6174748585be2dd4b132203cda8655b76251b Mon Sep 17 00:00:00 2001 From: Felix Lange Date: Tue, 22 Sep 2015 23:55:31 +0200 Subject: cmd/geth, core: make "geth blocktest" work again The test genesis block was not written properly, block insertion failed immediately. While here, fix the panic when shutting down "geth blocktest" with Ctrl+C. The signal handler is now installed automatically, causing ethereum.Stop to crash because everything is already stopped. --- cmd/geth/blocktestcmd.go | 6 ------ core/chain_manager.go | 1 + 2 files changed, 1 insertion(+), 6 deletions(-) diff --git a/cmd/geth/blocktestcmd.go b/cmd/geth/blocktestcmd.go index d3257ca4d..d6195e025 100644 --- a/cmd/geth/blocktestcmd.go +++ b/cmd/geth/blocktestcmd.go @@ -91,7 +91,6 @@ func runBlockTest(ctx *cli.Context) { if err != nil { utils.Fatalf("%v", err) } - defer ethereum.Stop() if rpc { fmt.Println("Block Test post state validated, starting RPC interface.") startEth(ctx, ethereum) @@ -106,7 +105,6 @@ func runOneBlockTest(ctx *cli.Context, test *tests.BlockTest) (*eth.Ethereum, er cfg.MaxPeers = 0 // disable network cfg.Shh = false // disable whisper cfg.NAT = nil // disable port mapping - ethereum, err := eth.New(cfg) if err != nil { return nil, err @@ -114,7 +112,6 @@ func runOneBlockTest(ctx *cli.Context, test *tests.BlockTest) (*eth.Ethereum, er // import the genesis block ethereum.ResetWithGenesisBlock(test.Genesis) - // import pre accounts _, err = test.InsertPreState(ethereum) if err != nil { @@ -122,16 +119,13 @@ func runOneBlockTest(ctx *cli.Context, test *tests.BlockTest) (*eth.Ethereum, er } cm := ethereum.ChainManager() - validBlocks, err := test.TryBlocksInsert(cm) if err != nil { return ethereum, fmt.Errorf("Block Test load error: %v", err) } - newDB := cm.State() if err := test.ValidatePostState(newDB); err != nil { return ethereum, fmt.Errorf("post state validation failed: %v", err) } - return ethereum, test.ValidateImportedHeaders(cm, validBlocks) } diff --git a/core/chain_manager.go b/core/chain_manager.go index 42f70af33..0ad4f86f9 100644 --- a/core/chain_manager.go +++ b/core/chain_manager.go @@ -279,6 +279,7 @@ func (bc *ChainManager) ResetWithGenesisBlock(genesis *types.Block) { if err := WriteBlock(bc.chainDb, genesis); err != nil { glog.Fatalf("failed to write genesis block: %v", err) } + bc.genesisBlock = genesis bc.insert(bc.genesisBlock) bc.currentBlock = bc.genesisBlock bc.setTotalDifficulty(genesis.Difficulty()) -- cgit v1.2.3 From 90cd8ae9f28b7caac93b5c8d555a11e6be90a9eb Mon Sep 17 00:00:00 2001 From: Felix Lange Date: Tue, 22 Sep 2015 23:59:26 +0200 Subject: rpc/api: don't crash for unknown blocks Most eth RPC calls that work with blocks crashed when the block was not found because they called Hash on a nil block. This is a regression introduced in cdc2662c409 (#1779). While here, remove the insane conversions in get*CountBy*. There is no need to construct a complete BlockRes and converting int->int64->*big.Int->[]byte->hexnum->string to format the length of a slice as hex. --- rpc/api/eth.go | 48 +++++++++++++++++++++++------------------------- 1 file changed, 23 insertions(+), 25 deletions(-) diff --git a/rpc/api/eth.go b/rpc/api/eth.go index 30366a951..4cd5f2695 100644 --- a/rpc/api/eth.go +++ b/rpc/api/eth.go @@ -210,7 +210,7 @@ func (self *ethApi) GetTransactionCount(req *shared.Request) (interface{}, error } count := self.xeth.AtStateNum(args.BlockNumber).TxCountAt(args.Address) - return newHexNum(big.NewInt(int64(count)).Bytes()), nil + return fmt.Sprintf("%#x", count), nil } func (self *ethApi) GetBlockTransactionCountByHash(req *shared.Request) (interface{}, error) { @@ -218,14 +218,11 @@ func (self *ethApi) GetBlockTransactionCountByHash(req *shared.Request) (interfa if err := self.codec.Decode(req.Params, &args);
