Interaction cleanups between main and wallet
2013-10-28Generalize the remove-outputs check for fully-prunable transactions.Pieter Wuille
Instead of explicitly testing for the presence of any output, and dealing with this case specially, just interpret it as an empty CCoins. The case previously caught using the HaveCoins check, is now handled by the generic outs != outsBlock test.

This required some code movement (what was CWalletTx::AcceptToMemoryPool doing in main?), and adding a few explicit includes that used to be implicit through init.h.

Changes the response to the 'mempool' command so that if the memory pool has more than MAX_INV_SZ transactions (50,000) it will respond with multiple 'inv' messages.

CBlockLocator improvements & move to core

2013-10-15Allow SendMessages to run partially without cs_mainPieter Wuille
SendMessages() tries to acquire a cs_main lock now, but this isn't nessecary for much of its functionality. Move those parts out of the locked section, so they can always be performed, and we hold cs_main for a shorter time.

2013-10-15Reimplement CBlockLocator's chain-related logic in CChain.Pieter Wuille
This removes a few unused CBlockLocator methods, and moves the construction and fork-finding logic to CChain (which can do these more efficiently, as it has a height-indexable chain available). It also makes CBlockLocator independent from the validation code.

2013-10-04Lower maximum size for free transaction creationGavin Andresen
Changes the maximum size of a free transaction that will be created from 10,000 bytes to 1,000 bytes. The idea behind this change is to make the free transaction area available to a greater number of people; with the default 27K-per-block, just three very-large very-high-priority transactions could fill the space.
2013-10-04Remove CENT-output free transaction rule when relayingGavin Andresen
Remove the (relay/mempool) rule that all outputs of free transactions must be greater than 0.01 XBT. Dust spam is now taken care of by making dusty outputs non-standard.

- rename URL into URI in paymentserver where correct - add some missing Qt-coding-stuff in paymentserver - change QSpinBox to QLineEdit as base for BitcoinAmountField in .ui files (as this is the result when converting the BAF back into base) - remove some c_str() and replace with QString::fromStdString() - remove several new-lines - remove unneeded spaces - indentation fixes
2013-09-09Longer term workaround for chainstate corruption from negative versions.Gregory Maxwell
This also makes negative transaction versions non-standard. This avoids an issue triggered in block 256818 where transactions with negative version numbers were incorrectly serialized into the UTXO set. On restart nodes detect the inconsistency and refuse to start so long as a block with these transactions is inside the self-consistency check window, logging "coin database inconsistencies found". The software recommends reindexing, but reindexing does not correct the problem. This should be fixed by changing the chainstate serialization, but working around it seems harmless for now because the version is not used by any network rule currently. A patch free workaround is to start with -checklevel=2 which skips the consistency checks, but the IsStandard change is important for miners in order to protect unpatched nodes.

2013-08-28[raw] reject insanely high fees by default in sendrawtransactionGregory Maxwell
There have been several incidents where mainnet experimentation with raw transactions resulted in insane fees. This is hard to prevent in the raw transaction api because the inputs may not be known. Since sending doesn't work if the inputs aren't known, we can catch it there. This rejects fees > than 10000 * nMinRelayTxFee or 1 BTC with the defaults and can be overridden with a bool at the rpc.
2013-08-28[wallet] Consider generated coins mature at COINBASE_MATURITY+1Gregory Maxwell
We're not seeing large reorgs that would justify waiting a large amount past the rule required maturity, and the extra three hours is just a nuisance. Take one more block to at least give the 100th block time to propagate.

This resulted in just passing all transactions to filtered wallets which worked surprisingly well, except where it didn't.
2013-08-20Performance optimization for bloom filters.Gregory Maxwell
This reduces a peer's ability to attack network resources by using a full bloom filter, but without reducing the usability of bloom filters. It sets a default match everything filter for peers and it generalizes a prior optimization to cover more cases.

2013-08-09Reject non-canonically-encoded sizesGavin Andresen
The length of vectors, maps, sets, etc are serialized using Write/ReadCompactSize -- which, unfortunately, do not use a unique encoding. So deserializing and then re-serializing a transaction (for example) can give you different bits than you started with. That doesn't cause any problems that we are aware of, but it is exactly the type of subtle mismatch that can lead to exploits. With this pull, reading a non-canonical CompactSize throws an exception, which means nodes will ignore 'tx' or 'block' or other messages that are not properly encoded. Please check my logic... but this change is safe with respect to causing a network split. Old clients that receive non-canonically-encoded transactions or blocks deserialize them into CTransaction/CBlock structures in memory, and then re-serialize them before relaying them to peers. And please check my logic with respect to causing a blockchain split: there are no CompactSize fields in the block header, so the block hash is always canonical. The merkle root in the block header is computed on a vector<CTransaction>, so any non-canonical encoding of the transactions in 'tx' or 'block' messages is erased as they are read into memory by old clients, and does not affect the block hash. And, as noted above, old clients re-serialize (with canonical encoding) 'tx' and 'block' messages before relaying to peers.
