Author	SHA1	Message	Date
zelig	3d57e377a4	blockpool stability fixes: ... - follow up locks and fix them - chainManager: call SetQueued for parentErr future blocks, uncomment TD checks, unskip test - make ErrIncorrectTD non-fatal to be forgiving to genuine mistaken nodes (temp) but demote them to guard against stuck best peers. - add purging to bounded nodeCache (config nodeCacheSize) - use nodeCache when creating blockpool entries and let non-best peers add blocks (performance boost) - minor error in addError - reduce idleBestPeerTimeout to 1 minute - correct status counts and unskip status passing status test - glogified logging	10 years ago
zelig	406feee570	bugfixes for headsection deadlocks ... - switchC initialised as closed - move select in setChainInfoFromBlock out of peer lock	10 years ago
zelig	da7332a731	td update from node ... - reorg and simplify AddBlock - introduce nodeCache - TestPeerPromotionByTdOnBlock unskipped and passes - move switchC/idleC channel creation around: solves deadlock (now respects the contract with section process: either can activate or complete at any one time)	10 years ago
obscuren	3755cfccb3	Skipped td test	10 years ago
obscuren	764a802eaa	Disabled TD check ... @zelig: Temporarily commented out TD check untill the rest of the network has been fixed.	10 years ago

zelig	a009132c24	oops peer unlocked before return - fixes deadlock	10 years ago
zelig	0e2bc23148	uncomment future block TD check, add test for skipping TD check on future block	10 years ago
zelig	e55747a074	fix deadlock issue in AddBlock ... - add peer switch channel arg to activateChain - no peer locking within - proper locking in AddBlock - fixes deadlock issue - comment out TD check and skip incorrect TD test again for hotfix	10 years ago
zelig	262714fc6c	future queued block support ... - queued bool // flag for blockpool to skip TD check - set to true when future block queued - in checkTD: skip check if queued - TODO: add test (insertchain sets future block)	10 years ago
zelig	cbd0b42060	put back checkTD and unskip incorrectTD test	10 years ago
zelig	f546b486bf	introduce peers registry on nodes ... - TestPeerPromotionByTdOnBlock renamed and skipped for now test should pass iff if TD is updated based on an agreement - senders register in AddBlock, flag records if they are coming from newblock message (and therefore advertise their TD with the block) or block message (TODO: latter are stored on the cache and updated by checkTD call; protocol should also call AddBlock on newblock messages by non-best peers) - remove TD update from optional TD field in addBlock: this is no longer part of the eth protocol spec -> TODO: reflect in wiki - only initialise peer map if at least two	10 years ago
zelig	42fb9652f5	fix blockpool deadlock ... - do not break from headsection on error [remove peer after protocol quit will close switchC, until then head block can arrive and block on channel while keeping peers lock causing a deadlock.] - more careful locking in AddBlock	10 years ago

obscuren	0d1a9ce648	Disabled peer TD check to support suspended blocks (Future blocks) ... @zelig When blocks are in the future they'll be cached and processed at a later time. Because of this the returned TD will be much lower than the broadcasted TD.	10 years ago

zelig	95038fc62d	Idle too long error incorrectly triggered even when peer sending new blocks ... - fix status chain map uses common.Hash as key - add badPeers increment to IncorrectTD errors (forgotten) - signal head info update to head section process even if parent hash is not in pool (inserted), so that idle timer can be set to nil - suicideC -> peer.headInfoTimer - quit -> peer.bestIdleTimer - and they are properly set from within getBlockHashes and handleSection	10 years ago

zelig	a9926a289d	fix missing hexification on IdleTooLong error log	10 years ago
zelig	391e89d70a	use own total difficulty to limit best peer ... - update blockpool td by subscribing to ChainHeadEvent - if ahead of best peer, demote it - addPeer now take own td as current td - removePeer now take own td as current td - add relevant tests to peers_test - eth: backend now calls blockpool with eth.eventMux and chainManager.Td	10 years ago

zelig	422490d75c	major rewrite, reorg of blockpool + new features ... - blockpool moves to its own package - uses errs pkg for its own coded errors - publicly settable config of params (time intervals and batchsizes) - test helpers in subpackage - optional TD in blocks used now to update peers chain info - major improvement in algorithm - fix fragility and sync/parallelisation bugs - implement status for reporting on sync status (peers/hashes/blocks etc) - several tests added and further corner cases covered	10 years ago
