Felix Lange	5c8fe28b72	common: move big integer math to common/math (#3699) ... * common: remove CurrencyToString Move denomination values to params instead. * common: delete dead code * common: move big integer operations to common/math This commit consolidates all big integer operations into common/math and adds tests and documentation. There should be no change in semantics for BigPow, BigMin, BigMax, S256, U256, Exp and their behaviour is now locked in by tests. The BigD, BytesToBig and Bytes2Big functions don't provide additional value, all uses are replaced by new(big.Int).SetBytes(). BigToBytes is now called PaddedBigBytes, its minimum output size parameter is now specified as the number of bytes instead of bits. The single use of this function is in the EVM's MSTORE instruction. Big and String2Big are replaced by ParseBig, which is slightly stricter. It previously accepted leading zeros for hexadecimal inputs but treated decimal inputs as octal if a leading zero digit was present. ParseUint64 is used in places where String2Big was used to decode a uint64. The new functions MustParseBig and MustParseUint64 are now used in many places where parsing errors were previously ignored. * common: delete unused big integer variables * accounts/abi: replace uses of BytesToBig with use of encoding/binary * common: remove BytesToBig * common: remove Bytes2Big * common: remove BigTrue * cmd/utils: add BigFlag and use it for error-checked integer flags While here, remove environment variable processing for DirectoryFlag because we don't use it. * core: add missing error checks in genesis block parser * common: remove String2Big * cmd/evm: use utils.BigFlag * common/math: check for 256 bit overflow in ParseBig This is supposed to prevent silent overflow/truncation of values in the genesis block JSON. Without this check, a genesis block that set a balance larger than 256 bits would lead to weird behaviour in the VM. * cmd/utils: fixup import	8 years ago

bas-vk	4e36b1e3da	core: bugfix state change race condition in txpool (#3412) ... The transaction pool keeps track of the current nonce in its local pendingState. When a new block comes in the pendingState is reset. During the reset it fetches multiple times the current state through the use of the currentState callback. When a second block comes in during the reset its possible that the state changes during the reset. If that block holds transactions that are currently in the pool the local pendingState that is used to determine nonces can get out of sync.	8 years ago

Jeffrey Wilcke	f0cbebb19f	core: added basic chain configuration ... Added chain configuration options and write out during genesis database insertion. If no "config" was found, nothing is written to the database. Configurations are written on a per genesis base. This means that any chain (which is identified by it's genesis hash) can have their own chain settings.	9 years ago

Jeffrey Wilcke	eaa4473dbd	core, core/types: readd transactions after chain re-org ... Added a `Difference` method to `types.Transactions` which sets the receiver to the difference of a to b (NOTE: not a **and** b). Transaction pool subscribes to RemovedTransactionEvent adding back to those potential missing from the chain. When a chain re-org occurs remove any transactions that were removed from the canonical chain during the re-org as well as the receipts that were generated in the process. Closes #1746	9 years ago
Jeffrey Wilcke	b60a27627b	core: transaction nonce recovery fix ... When the transaction state recovery kicked in it assigned the last (incorrect) nonce to the pending state which caused transactions with the same nonce to occur. Added test for nonce recovery	9 years ago

Jeffrey Wilcke	61ca780f3b	core: reduce CPU load by reducing calls to checkQueue ... * Reduced maxQueue count * Added proper deletion past maxQueue limit * Added cheap stats method to txpool queueCheck was called for **every** transaction instead of: 1. add all txs 2. check queue previously 1. add txs[i] 2. check queue 3. if i < len(txs) goto 1.	9 years ago

obscuren	d09a6e5421	core, eth, miner: moved nonce management to tx pool. ... Removed the managed tx state from the chain manager to the transaction pool where it's much easier to keep track of nonces (and manage them). The transaction pool now also uses the queue and pending txs differently where queued txs are now moved over to the pending queue (i.e. txs ready for processing and propagation).	10 years ago

obscuren	6184781b49	Improved transaction pool ... The transaction pool will now some easily be able to pre determine the validity of a transaction by checking the following: * Account existst * gas limit higher than the instrinsic gas * enough funds to pay upfront costs * nonce check	10 years ago
