obscuren 764a802eaa Disabled TD check
@zelig: Temporarily commented out TD check untill the rest of the network has
been fixed.

zelig be25396340 separate lock for blacklist 2015-04-09 13:58:35 +01:00
zelig a009132c24 oops peer unlocked before return - fixes deadlock 2015-04-09 13:58:35 +01:00
zelig 0e2bc23148 uncomment future block TD check, add test for skipping TD check on future block 2015-04-09 13:58:35 +01:00
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

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

zelig 30830652ae fix TestPoolStatus test crashing, skip tests failing (due to @obscuren hotfixes) 2015-04-09 13:58:35 +01:00
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.

zelig 5cb1b41440 proper locking to prevent "parent unknown" INVALID blocks due to race in peer head info update 2015-04-02 16:30:48 +01:00
zelig dd1791c9fd proper locking to prevent close of closed channel crash when multiple mining peers compete 2015-04-02 15:32:41 +01:00
zelig 9d592c0445 bugfix with idle too long triggered after peer switch
- reset bestIdleTimer when launching head section process
- log chain head events
- common.Hash key in activateChain map

obscuren c8e9ca0483 fixed bad uncles 2015-03-23 18:27:05 +01:00
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

zelig 137a9c9365 check and penalise td misreporting
- add ErrIncorrectTD
- checkTD called after insertChain successful
- fix tests, use blockPoolTester.tds to map block index to TD

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

zelig a60a18b080 - fix peer disconnect by adding severity function to errs
- improve logging
- suicide -> removeChain
- improved status BlocksInPool calculation
2015-03-03 00:43:12 +07:00
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
