Jeffrey Wilcke	558d18d2b0	core: added future proc mutex lock ... Added a future lock which prevents the anything being added or removed from or to the set when looping over the set of blocks. This fixes a nil pointer in the range loop when trying to retrieve a block from the set which was previously available but removed due to regular chain processing. Fixes #2305	9 years ago
Péter Szilágyi	daad2b2559	core: cache fresh headers and tds to avoid db trashing	9 years ago
zsfelfoldi	73d21ea6af	core: create a header chain structure shared by core.BlockChain and light.LightChain	9 years ago
Péter Szilágyi	e90958cd29	cmd, eth, ethdb, node: prioritise chaindata for resources, bump cache	9 years ago
Jeffrey Wilcke	ba3fb9e6f4	core: announce ChainSideEvent during reorg ... Previously all blocks that were already in our chain were never re announced as potential uncle block (e.g. ChainSideEvent). This is problematic during mining where you want to gather as much possible uncles as possible increasing the profit. This is now addressed in this PR where during reorganisations of chains the old chain is regarded as uncles. Fixed #2298	9 years ago
Péter Szilágyi	b534106cc8	core, miner: add PendingStateEvent to track non-log updates	9 years ago
Ricardo Catalinas Jiménez	436fc8d76a	all: Rename crypto.Sha3{,Hash}() to crypto.Keccak256{,Hash}() ... As we aren't really using the standarized SHA-3	9 years ago
Jeffrey Wilcke	5b283663b4	core: Added new TD strategy which mitigate the risk for selfish mining ... Assuming the following scenario where a miner has 15% of all hashing power and the ability to exert a moderate control over the network to the point where if the attacker sees a message A, it can't stop A from propagating, but what it **can** do is send a message B and ensure that most nodes see B before A. The attacker can then selfish mine and augment selfish mining strategy by giving his own blocks an advantage. This change makes the time at which a block is received less relevant and so the level of control an attacker has over the network no longer makes a difference. This change changes the current td algorithm `B_td > C_td` to the new algorithm `B_td > C_td || B_td == C_td && rnd < 0.5`.	9 years ago
Jeffrey Wilcke	b6d88a0e9f	core, core/vm, crypto: fixes for homestead ... * Removed some strange code that didn't apply state reverting properly * Refactored code setting from vm & state transition to the executioner * Updated tests	9 years ago
Gustav Simonsson	371871d685	parmas, crypto, core, core/vm: homestead consensus protocol changes ... * change gas cost for contract creating txs * invalidate signature with s value greater than secp256k1 N / 2 * OOG contract creation if not enough gas to store code * new difficulty adjustment algorithm * new DELEGATECALL op code	9 years ago
Péter Szilágyi	b8d59d9c98	core/state, trie: switch iterator panics to error fields	9 years ago

Bas van Kervel	0ff2adb21b	core: improved check for contract creation	9 years ago
Jeffrey Wilcke	987c1a595a	eth/filters: ✨ pending logs ✨ ... Pending logs are now filterable through the Go API. Filter API changed such that each filter type has it's own bucket and adding filter explicitly requires you specify the bucket to put it in.	9 years ago
Jeffrey Wilcke	6cace73bea	core/vm/runtime: simplified runtime calling mechanism ... Implemented `runtime.Call` which uses - unlike Execute - the given state for the execution and the address of the contract you wish to execute. Unlike `Execute`, `Call` requires a config.	9 years ago
Peter Pratscher	15780ead07	core/vm, rpc/api: renamed to debug.replayTransaction, migrated to new RPC, integrated feedback ... Integrated code review suggestions Integrated last review comments	9 years ago
Péter Szilágyi	d3642b0715	core, eth, rpc/api: rpc method to inspect the txpool queue	9 years ago
Péter Szilágyi	a2dc074b1d	core, core/types, miner: fix transaction nonce-price combo sort	9 years ago
Péter Szilágyi	f3d4ce0d16	core/state, ethdb, trie: test intermediate secure key leak, fix memdb bug	9 years ago
Péter Szilágyi	886478b18b	core/state, trie: don't leak database writes before commit	9 years ago
Péter Szilágyi	2d5d6d9d0e	core/state: always commit in batches, just finish if not needed later	9 years ago
Péter Szilágyi	752c75fb21	core/vm: resolve circular dependency to debug vm storage	9 years ago
Péter Szilágyi	e5b480b638	core: fix invalid state reuse in chain maker based tests	9 years ago

Péter Szilágyi	9e011ff1cd	core, eth/downloader: ensure state presence in ancestor lookup	9 years ago
Felix Lange	e6fb69296e	common: remove old RLP implementation, Value and ExtPackage ... In order to make this happen, kill all remaining trivial uses of common/{rlp,value}.go. The non-trivial ones have been updated earlier.	9 years ago
Felix Lange	1b89bd5d26	core/state, core/types use package rlp for state, receipt serialisation	9 years ago
Felix Lange	9be5d5cd90	eth/downloader: fix negative balance issue in tests ... The test chain generated by makeChainFork included invalid uncle headers, crashing the generator during the state commit. The headers were invalid because they used the iteration counter as the block number, even though makeChainFork uses a block with number > 0 as the parent. Fix this by introducing BlockGen.Number, which allows accessing the actual number of the block being generated.	9 years ago
zsfelfoldi	975c591261	core: tx pool skip price validation for "owned" transactions	9 years ago
Bas van Kervel	eae81465c1	rpc: new RPC implementation with pub/sub support	9 years ago
Péter Szilágyi	1cecda8333	core: write individual transactions and receipts too on fast sync	9 years ago
Jeffrey Wilcke	9901a40f04	core: added a new RemovedLogEvent ... When a chain reorganisation occurs we collect the logs that were deleted during the chain reorganisation. The removed logs are posted to the event mux indicating that those were deleted during the reorg.	9 years ago
Péter Szilágyi	1e806c4c77	cmd, common, core, eth, node, rpc, tests, whisper, xeth: use protocol stacks	9 years ago
Péter Szilágyi	e86e0ecdc8	core, eth, miner, xeth: clean up tx/receipt db accessors	9 years ago
Jeffrey Wilcke	1372b991c3	core/vm/runtime: added simple execution runtime ... The runtime environment can be used for simple basic execution of contract code without the requirement of setting up a full stack and operates fully in memory.	9 years ago
Jeffrey Wilcke	a1d9ef48c5	core, eth, rpc: split out block validator and state processor ... This removes the burden on a single object to take care of all validation and state processing. Now instead the validation is done by the `core.BlockValidator` (`types.Validator`) that takes care of both header and uncle validation through the `ValidateBlock` method and state validation through the `ValidateState` method. The state processing is done by a new object `core.StateProcessor` (`types.Processor`) and accepts a new state as input and uses that to process the given block's transactions (and uncles for rewords) to calculate the state root for the next block (P_n + 1).	9 years ago
Péter Szilágyi	667987e7d0	core: only reset head header/fastblock if stale	9 years ago
Péter Szilágyi	28c7b54d68	core: fix #1921, decode all receipt field, not just consensus	9 years ago
Péter Szilágyi	5b0ee8ec30	core, eth, trie: fix data races and merge/review issues	9 years ago
Jeffrey Wilcke	80f26086ee	core, tests: get_hash fix ... Make sure that we're fetching the hash from the current chain and not the canonical chain.	9 years ago
