5eaaa83 Kill insecure_random and associated global state (Wladimir J. van der Laan)
2016-10-17Kill insecure_random and associated global stateWladimir J. van der Laan
There are only a few uses of `insecure_random` outside the tests. This PR replaces uses of insecure_random (and its accompanying global state) in the core code with an FastRandomContext that is automatically seeded on creation. This is meant to be used for inner loops. The FastRandomContext can be in the outer scope, or the class itself, then rand32() is used inside the loop. Useful e.g. for pushing addresses in CNode or the fee rounding, or randomization for coin selection. As a context is created per purpose, thus it gets rid of cross-thread unprotected shared usage of a single set of globals, this should also get rid of the potential race conditions. - I'd say TxMempool::check is not called enough to warrant using a special fast random context, this is switched to GetRand() (open for discussion...) - The use of `insecure_rand` in ConnectThroughProxy has been replaced by an atomic integer counter. The only goal here is to have a different credentials pair for each connection to go on a different Tor circuit, it does not need to be random nor unpredictable. - To avoid having a FastRandomContext on every CNode, the context is passed into PushAddress as appropriate. There remains an insecure_random for test usage in `test_random.h`.

2016-03-21Implement "feefilter" P2P message.Alex Morcos
The "feefilter" p2p message is used to inform other nodes of your mempool min fee which is the feerate that any new transaction must meet to be accepted to your mempool. This will allow them to filter invs to you according to this feerate.
2016-03-18Policy: allow transaction version 2 relay policy.BtcDrak
This commit introduces a way to gracefully bump the default transaction version in a two step process.
2016-02-14BIP112: Implement CHECKSEQUENCEVERIFYMark Friedenbach
- Replace NOP3 with CHECKSEQUENCEVERIFY (BIP112) <nSequence> CHECKSEQUENCEVERIFY -> <nSequence> - Fails if txin.nSequence < nSequence, allowing funds of a txout to be locked for a number of blocks or a duration of time after its inclusion in a block. - Pull most of CheckLockTime() out into VerifyLockTime(), a local function that will be reused for CheckSequence() - Add bitwise AND operator to CScriptNum - Enable CHECKSEQUENCEVERIFY as a standard script verify flag - Transactions that fail CSV verification will be rejected from the mempool, making it easy to test the feature. However blocks containing "invalid" CSV-using transactions will still be accepted; this is *not* the soft-fork required to actually enable CSV for production use.

2015-11-30Change default block priority size to 0Alex Morcos
Make RPC tests have a default block priority size of 50000 (the old default) so we can still use free transactions in RPC tests. When priority is eliminated, we will have to make a different change if we want to continue allowing free txs.

2015-11-16EstimateSmart functions consider mempool min feeAlex Morcos
2015-11-16Increase success threshold for fee estimation to 95%Alex Morcos
This provides more conservative estimates and reacts more quickly to a backlog. Unfortunately the unit test for fee estimation depends on the success threshold (and the decay) chosen; also modify the unit test for the new default success thresholds.
2015-11-16Add smart fee estimation functionsAlex Morcos
These are more useful fee and priority estimation functions. If there is no fee/pri high enough for the target you are aiming for, it will give you the estimate for the lowest target that you can reliably obtain. This is better than defaulting to the minimum. It will also pass back the target for which it returned an answer.

2015-11-03Restore MedianTimePast for locktime.Gregory Maxwell
Revert "Revert "Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations"" This reverts commit 40cd32e835092c3158175511da5193193ec54939. After careful analysis it was determined that the change was, in fact, safe and several people were suffering momentary confusion about locktime semantics.
