2012-02-01Avoid advertising the node's address when it is not listening or ↵Gregory Maxwell
IsInitialBlockDownload(). This also avoids flushing setAddrKnown until 24 hours has passed, and avoids contacting the external IP services when not listening. Advertising non-listening nodes is just addr message spam. It doesn't help the network, in fact it hurts the network, and it also hurts user's privacy. Advertising far out of sync nodes doesn't help the network— they can't even forward (most) transactions and wastes nodes outbound slots.
2012-01-31Testnet difficulty calculation changes, to take effect Feb 15 2012Gavin Andresen
Allow mining of min-difficulty blocks if 20 minutes have gone by without mining a regular-difficulty block. Normal rules apply every 2016 blocks, though, so there may be a very-slow-to-confirm block at the difficulty-adjustment blocks.

All previous versions of bitcoin could store some types of invalid transactions in the orphan-transaction list.

Correct comment for why the check is unnecessary for coinbases Move testnet check out, to AcceptToMemoryPool where everything else checks it
2012-01-20Simplify counting of P2SH sigops to match BIP 16 (thanks to Matt Corallo for ↵Gavin Andresen
prompting this). This also removes an un-needed sigops-per-byte check when accepting transactions to the memory pool (un-needed assuming only standard transactions are being accepted). And it only counts P2SH sigops after the switchover date.

-blocknotify : run a command when best-block changes
2012-01-06Network stack refactorPieter Wuille
This introduces CNetAddr and CService, respectively wrapping an (IPv6) IP address and an IP+port combination. This functionality used to be part of CAddress, which also contains network flags and connection attempt information. These extra fields are however not always necessary. These classes, along with logic for creating connections and doing name lookups, are moved to netbase.{h,cpp}, which does not depend on headers.h. Furthermore, CNetAddr is mostly IPv6-ready, though IPv6 functionality is not yet enabled for the application itself.

so it takes a flag for how to interpret OP_EVAL. Also increased IsStandard size of scriptSigs to 500 bytes, so a 3-of-3 multisig transaction IsStandard.

2011-12-19OP_EVAL implementationGavin Andresen
OP_EVAL is a new opcode that evaluates an item on the stack as a script. It enables a new type of bitcoin address that needs an arbitrarily complex script to redeem.

2011-12-14Bugfix: fForRelay should be false when deciding required fee to include in ↵Luke Dashjr
blocks During the rushed transition from 0.01 BTC to 0.0005 BTC fees, we took the approach of dropping the relay and block-inclusion fee to 0.0005 BTC immediately, and only delayed adjusting the sending fee for the next release. Afterward, the relay fee was lowered to 0.0001 BTC to avoid having the same problem in the future. However, the block inclusion code was left setting fForRelay to true! This fixes that, so the lower 0.0001 BTC allowance is (as intended) only permitted for real relaying.
