Péter Szilágyi	710435b51b	core, eth, trie: reuse trie journals in all our code	8 years ago
Felix Lange	a59a93f476	core/state: track all accounts in canon state ... This change introduces a global, per-state cache that keeps account data in the canon state. Thanks to @karalabe for lots of fixes.	8 years ago
Bas van Kervel	bb8059f6aa	core: ensure the canonical block is written before the canonical hash is set	8 years ago
Péter Szilágyi	f5a29eab5c	core: solve a remote-import/local-mine data race	8 years ago
zsfelfoldi	f9917c8c7b	core: improved chainDb using sequential keys	9 years ago
Péter Szilágyi	748d1c171d	core, core/state, trie: enterprise hand-tuned multi-level caching	9 years ago
Felix Lange	ca18202eb9	eth: enable bad block reports ... We used to have reporting of bad blocks, but it was disabled before the Frontier release. We need it back because users are usually unable to provide the full RLP data of a bad block when it occurs. A shortcoming of this particular implementation is that the origin peer is not tracked for blocks received during eth/63 sync. No origin peer info is still better than no report at all though.	9 years ago
Nicholas Johnson	c74a575725	core: Provide a public accessor for ChainConfig ... This is necessary for external users of the go-ethereum code who want to, for instance, build a custom node that plays back transactions, as core.ApplyTransaction requires a ChainConfig as a parameter.	9 years ago
Felix Lange	6fdd0893c3	all: fix go vet warnings	9 years ago
Felix Lange	24cdac41f3	core, core/types, eth: add and use Block.Body ... This fixes a few uses of unkeyed Body literals which go vet was complaining about.	9 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	0cfa21fc7f	core, eth, cmd: temporary work around for enabling the jit ... This commit serves as a temporary workaround for enabling the jit until the block customisation PR is merged in.	9 years ago
Jeffrey Wilcke	14013372ae	core: Added EVM configuration options ... The EVM is now initialised with an additional configured object that allows you to turn on debugging options.	9 years ago
Leif Jurvetson	434e4b31d8	core, eth: replace reorganiz with reorganis	9 years ago
Leif Jurvetson	c7727191ae	core: fixed various typos	9 years ago
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
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
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	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
Péter Szilágyi	9e011ff1cd	core, eth/downloader: ensure state presence in ancestor lookup	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	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	5b0ee8ec30	core, eth, trie: fix data races and merge/review issues	9 years ago
Péter Szilágyi	a9d8dfc8e7	core, eth: roll back uncertain headers in failed fast syncs	9 years ago
Péter Szilágyi	b97e34a8e4	eth/downloader: concurrent receipt and state processing	9 years ago
Péter Szilágyi	ab27bee25a	core, eth, trie: direct state trie synchronization	9 years ago
Péter Szilágyi	832b37c822	core, eth: receipt chain reconstruction	9 years ago
Péter Szilágyi	b99fe27f8b	core: fix block canonical mark / content write race	9 years ago
Péter Szilágyi	c33cc382b3	core: support inserting pure header chains	9 years ago
Jeffrey Wilcke	6dc14788a2	core, eth/filters, miner, xeth: Optimised log filtering ... Log filtering is now using a MIPmap like approach where addresses of logs are added to a mapped bloom bin. The current levels for the MIP are in ranges of 1.000.000, 500.000, 100.000, 50.000, 1.000. Logs are therefor filtered in batches of 1.000.	9 years ago
Gustav Simonsson	1b1f293082	core/state, core, miner: handle missing root error from state.New	9 years ago
Péter Szilágyi	402fd6e8c6	core, eth, event, miner, xeth: fix event post / subscription race	9 years ago
Jeffrey Wilcke	20ab29f885	core: fixed head write on block insertion ... Due to a rebase this probably got overlooked / ignored. This fixes the issue of a block insertion never writing the last block.	9 years ago
Jeffrey Wilcke	7c7692933c	cmd/geth, cmd/utils, core, rpc: renamed to blockchain ... * Renamed ChainManager to BlockChain * Checkpointing is no longer required and never really properly worked when the state was corrupted.	9 years ago
Jeffrey Wilcke	a6cc02f68f	core: deadlock in chainmanager after posting RemovedTransactionEvent ... This PR solves an issue with the chain manager posting a `RemovedTransactionEvent`, the tx pool will try to acquire the chainmanager lock which has previously been locked prior to posting `RemovedTransactionEvent`. This results in a deadlock in the core.	9 years ago
Felix Lange	70b6174748	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.	9 years ago
Felix Lange	a2d5a60418	core, core/state: batch-based state sync	9 years ago
Gustav Simonsson	bfde1a4305	core: Add BadHashErr and test for BadHashes handling	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
