As of this commit, p2p will disconnect nodes directly after the
encryption handshake if too many peer connections are active.
Errors in the protocol handshake packet are now handled more politely
by sending a disconnect packet before closing the connection.
There were multiple synchronization issues in the disconnect handling,
all caused by the odd special-casing of Peer.readLoop errors. Remove the
special handling of read errors and make readLoop part of the Peer
WaitGroup.
Thanks to @Gustav-Simonsson for pointing at arrows in a diagram
and playing rubber-duck.
* Add initial go wrapping for TransactionTests with some tests
disabled in lieu of consistent HEX encodings and a few other
pending bugfixes
* TODO: Consider better way of perhaps modelling each test in
the JSON files as a single Go test, instead of one Go test per
JSON file
Fetching the recipient address from a transaction was changed to return nil
instead of a zero-address, but this code path was not updated, so whenever
a contract was created, a nil panic occured.
- 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
- 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)
- 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
- 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
Removed the from as a requiremet from the RPC eth_call. Xeth#Call now
also default values to:
1. Supplied account
2. First account if any
3. No managed account => 000000..00
