2014-10-22CAutoFile: Explicit Get() and remove unused methodsWladimir J. van der Laan
Also add documentation to some methods.

2014-10-14Headers-first synchronizationPieter Wuille
Many changes: * Do not use 'getblocks', but 'getheaders', and use it to build a headers tree. * Blocks are fetched in parallel from all available outbound peers, using a limited moving window. When one peer stalls the movement of the window, it is disconnected. * No more orphan blocks. At all. We only ever request a block for which we have verified the headers, and store it to disk immediately. This means that a disk-fill attack would require PoW. * Require protocol version 31800 for every peer (released in december 2010). * No more syncnode (we sync from everyone we can, though limited to 1 during initial *headers* sync). * Introduce some extra named constants, comments and asserts.

2014-09-10netbase: Make SOCKS5 negotiation interruptibleWladimir J. van der Laan
Avoids that SOCKS5 negotiation will hold up the shutdown process. - Sockets can stay in non-blocking mode, no need to switch it on/off anymore - Adds a timeout (20 seconds) on SOCK5 negotiation. This should be enough for even Tor to get a connection to a hidden service, and avoids blocking the opencon thread indefinitely on a hanging proxy. Fixes #2954.

2014-08-26Split up util.cpp/hWladimir J. van der Laan
Split up util.cpp/h into: - string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach) - money utilities (parsesmoney, formatmoney) - time utilities (gettime*, sleep, format date): - and the rest (logging, argument parsing, config file parsing) The latter is basically the environment and OS handling, and is stripped of all utility functions, so we may want to rename it to something else than util.cpp/h for clarity (Matt suggested osinterface). Breaks dependency of sha256.cpp on all the things pulled in by util.

2014-07-17Convert closesocket 'compat wrapper' to function in netbaseWladimir J. van der Laan
Simpler alternative to #4348. The current setup with closesocket() is strange. It poses as a compatibility wrapper but adds functionality. Rename it and make it a documented utility function in netbase. Code movement only, zero effect on the functionality.

2014-07-09Introduce whitelisted peers.Pieter Wuille
This adds a -whitelist option to specify subnet ranges from which peers that connect are whitelisted. In addition, there is a -whitebind option which works like -bind, except peers connecting to it are also whitelisted (allowing a separate listen port for trusted connections). Being whitelisted has two effects (for now): * They are immune to DoS disconnection/banning. * Transactions they broadcast (which are valid) are always relayed, even if they were already in the mempool. This means that a node can function as a gateway for a local network, and that rebroadcasts from the local network will work as expected. Whitelisting replaces the magic exemption localhost had for DoS disconnection (local addresses are still never banned, though), which implied hidden service connects (from a localhost Tor node) were incorrectly immune to DoS disconnection as well. This old behaviour is removed for that reason, but can be restored using -whitelist=127.0.0.1 or -whitelist=::1 can be specified. -whitebind is safer to use in case non-trusted localhost connections are expected (like hidden services).

2014-06-23build: fix build weirdness after 54372482.Cory Fields
bitcoin-config.h moved, but the old file is likely to still exist when reconfiguring or switching branches. This would've caused files to not rebuild correctly, and other strange problems. Make the path explicit so that the old one cannot be found. Core libs use config/bitcoin-config.h. Libs (like crypto) which don't want access to bitcoin's headers continue to use -Iconfig and #include bitcoin-config.h.
