* remove GetBoolArg() fDefault parameter defaulting to falsePhilip Kaufmann2013-06-011-2/+2
| | | | | | | | - explicitly set the default of all GetBoolArg() calls - rework getarg_test.cpp and util_tests.cpp to cover this change - some indentation fixes - move macdockiconhandler.h include in bitcoin.cpp to the "our headers" section

| * Make FindBlockByHeight constant-time.Pieter Wuille2013-05-121-34/+20
| | | | | | | | | | | | | | | | | | | | | | | | Remove the pnext pointer in CBlockIndex, and replace it with a vBlockIndexByHeight vector (no effect on memory usage). pnext can now be replaced by vBlockIndexByHeight[nHeight+1], but FindBlockByHeight becomes constant-time. This also means the entire mapBlockIndex structure and the block index entries in it become purely blocktree-related data, and independent from the currently active chain, potentially allowing them to be protected by separate mutexes in the future.

| | | | | | | | | | | | | | | | | | | | Write bestblock records in wallets: * Every 20160 blocks synced, no matter what (before: none during IBD) * Every 144 blocks after IBD (before: for every block, slow) * When creating a new wallet * At shutdown This should result in far fewer spurious rescans.

* Use a uint256 for bnChainWorkPieter Wuille2013-04-121-23/+25
| | | | | | | | | Every block index entry currently requires a separately-allocated CBigNum. By replacing them with uint256, it's just 32 bytes extra in CBlockIndex itself. This should save us a few megabytes in RAM, and less allocation overhead.

|/ | | | | | | | | This introduces the concept of the 'sync node', which is the one we asked for missing blocks. In case the sync node goes away, a new one will be selected. For now, the heuristic is very simple, but it can easily be extended later to add better policies.

| | | | | | | | | | | | | | | | | | | | | | | | Two reasons for this change: 1. Need to always use boost::thread's sleep, even on Windows, so the sleeps can be interrupted (prior code used Windows' built-in Sleep). 2. I always forgot what units the old Sleep took.

* | Process getdata invs separately until send buffer overflowsPieter Wuille2013-03-301-94/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There exists a per-message-processed send buffer overflow protection, where processing is halted when the send buffer is larger than the allowed maximum. This protection does not apply to individual items, however, and getdata has the potential for causing large amounts of data to be sent. In case several hundreds of blocks are requested in one getdata, the send buffer can easily grow 50 megabytes above the send buffer limit. This commit breaks up the processing of getdata requests, remembering them inside a CNode when too many are requested at once.

* | P2P: parse network datastream into header/data components in socket threadJeff Garzik2013-03-291-38/+27
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replaces CNode::vRecv buffer with a vector of CNetMessage's. This simplifies ProcessMessages() and eliminates several redundant data copies. Overview: * socket thread now parses incoming message datastream into header/data components, as encapsulated by CNetMessage * socket thread adds each CNetMessage to a vector inside CNode * message thread (ProcessMessages) iterates through CNode's CNetMessage vector Message parsing is made more strict: * Socket is disconnected, if message larger than MAX_SIZE or if CMessageHeader deserialization fails (latter is impossible?). Previously, code would simply eat garbage data all day long. * Socket is disconnected, if we fail to find pchMessageStart. We do not search through garbage, to find pchMessageStart. Each message must begin precisely after the last message ends. ProcessMessages() always processes a complete message, and is more efficient: * buffer is always precisely sized, using CDataStream::resize(), rather than progressively sized in 64k chunks. More efficient for large messages like "block". * whole-buffer memory copy eliminated (vRecv -> vMsg) * other buffer-shifting memory copies eliminated (vRecv.insert, vRecv.erase)

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extremely large transactions with lots of inputs can cost the network almost as much to process as they cost the sender in fees. We would never create transactions larger than 100K big; this change makes transactions larger than 100K non-standard, so they are not relayed/mined by default. This is most important for miners that might create blocks larger than 250K big, who could be vulnerable to a make-your-blocks-so-expensive-to-verify-they-get-orphaned attack.
