* blockpool stability fixes:zelig2015-04-138-344/+356
| | | | | | | | | | | | - 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
* bugfixes for headsection deadlockszelig2015-04-111-7/+15
| | | | | - switchC initialised as closed - move select in setChainInfoFromBlock out of peer lock
* td update from nodezelig2015-04-104-139/+148
| | | | | | | - 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)
* Skipped td testobscuren2015-04-101-0/+1

* Disabled TD checkobscuren2015-04-092-0/+4
| | | | | @zelig: Temporarily commented out TD check untill the rest of the network has been fixed.

|
* fix deadlock issue in AddBlockzelig2015-04-094-39/+46
| | | | | | - 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
* future queued block supportzelig2015-04-091-1/+2
| | | | | | | - 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)
* put back checkTD and unskip incorrectTD testzelig2015-04-092-5/+5
|
* introduce peers registry on nodeszelig2015-04-092-43/+41
| | | | | | | | | | | | - 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
* fix blockpool deadlockzelig2015-04-093-12/+22
| | | | | | - 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

* Disabled peer TD check to support suspended blocks (Future blocks)obscuren2015-04-042-6/+6
| | | | | | @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.

* | Idle too long error incorrectly triggered even when peer sending new blockszelig2015-03-224-28/+31
|/ | | | | | | | | - 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

* major rewrite, reorg of blockpool + new featureszelig2015-02-2513-0/+3583
- 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
