build: fix build weirdness after 54372482. 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.

evhttpd implementation - *Replace usage of boost::asio with [libevent2](http://libevent.org/)*. boost::asio is not part of C++11, so unlike other boost there is no forwards-compatibility reason to stick with it. Together with #4738 (convert json_spirit to UniValue), this rids Bitcoin Core of the worst offenders with regard to compile-time slowness. - *Replace spit-and-duct-tape http server with evhttp*. Front-end http handling is handled by libevent, a work queue (with configurable depth and parallelism) is used to handle application requests. - *Wrap HTTP request in C++ class*; this makes the application code mostly HTTP-server-neutral - *Refactor RPC to move all http-specific code to a separate file*. Theoreticaly this can allow building without HTTP server but with another RPC backend, e.g. Qt's debug console (currently not implemented) or future RPC mechanisms people may want to use. - *HTTP dispatch mechanism*; services (e.g., RPC, REST) register which URL paths they want to handle. By using a proven, high-performance asynchronous networking library (also used by Tor) and HTTP server, problems such as #5674, #5655, #344 should be avoided. What works? bitcoind, bitcoin-cli, bitcoin-qt. Unit tests and RPC/REST tests pass. The aim for now is everything but SSL support. Configuration options: - `-rpcthreads`: repurposed as "number of work handler threads". Still defaults to 4. - `-rpcworkqueue`: maximum depth of work queue. When this is reached, new requests will return a 500 Internal Error. - `-rpctimeout`: inactivity time, in seconds, after which to disconnect a client. - `-debug=http`: low-level http activity logging

key.cpp: fail with a friendlier message on missing ssl EC support Previously if bitcoind is linked with an OpenSSL which is compiled without EC support, this is seen as an assertion failure "pKey != NULL" at key.cpp:134, which occurs after several seconds. It is an esoteric piece of knowledge to interpret this as "oops, I linked with the wrong OpenSSL", and because of the delay it may not even be noticed. The new output is : OpenSSL appears to lack support for elliptic curve cryptography. For more information, visit https://en.bitcoin.it/wiki/OpenSSL_and_EC_Libraries : Initialization sanity check failed. Bitcoin Core is shutting down. which occurs immediately after attempted startup. This also blocks in an InitSanityCheck() function which currently only checks for EC support but should eventually do more. See #4081.

net: Automatically create hidden service, listen on Tor Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket API, to create and destroy 'ephemeral' hidden services programmatically. https://stem.torproject.org/api/control.html#stem.control.Controller.create_ephemeral_hidden_service This means that if Tor is running (and proper authorization is available), bitcoin automatically creates a hidden service to listen on, without user manual configuration. This will positively affect the number of available .onion nodes. - When the node is started, connect to Tor through control socket - Send `ADD_ONION` command - First time: - Make it create a hidden service key - Save the key in the data directory for later usage - Make it redirect port 8333 to the local port 8333 (or whatever port we're listening on). - Keep control socket connection open for as long node is running. The hidden service will (by default) automatically go away when the connection is closed.

Introduce whitelisted peers. 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).

estimatefee / estimatepriority RPC methods New RPC methods: return an estimate of the fee (or priority) a transaction needs to be likely to confirm in a given number of blocks. Mike Hearn created the first version of this method for estimating fees. It works as follows: For transactions that took 1 to N (I picked N=25) blocks to confirm, keep N buckets with at most 100 entries in each recording the fees-per-kilobyte paid by those transactions. (separate buckets are kept for transactions that confirmed because they are high-priority) The buckets are filled as blocks are found, and are saved/restored in a new fee_estiamtes.dat file in the data directory. A few variations on Mike's initial scheme: To estimate the fee needed for a transaction to confirm in X buckets, all of the samples in all of the buckets are used and a median of all of the data is used to make the estimate. For example, imagine 25 buckets each containing the full 100 entries. Those 2,500 samples are sorted, and the estimate of the fee needed to confirm in the very next block is the 50'th-highest-fee-entry in that sorted list; the estimate of the fee needed to confirm in the next two blocks is the 150'th-highest-fee-entry, etc. That algorithm has the nice property that estimates of how much fee you need to pay to get confirmed in block N will always be greater than or equal to the estimate for block N+1. It would clearly be wrong to say "pay 11 uBTC and you'll get confirmed in 3 blocks, but pay 12 uBTC and it will take LONGER". A single block will not contribute more than 10 entries to any one bucket, so a single miner and a large block cannot overwhelm the estimates.

Together with #4738 (convert json_spirit to UniValue), this rids Bitcoin Core of the worst offenders with regard to compile-time slowness. - *Replace spit-and-duct-tape http server with evhttp*. Front-end http handling is handled by libevent, a work queue (with configurable depth and parallelism) is used to handle application requests. - *Wrap HTTP request in C++ class*; this makes the application code mostly HTTP-server-neutral - *Refactor RPC to move all http-specific code to a separate file*. Theoreticaly this can allow building without HTTP server but with another RPC backend, e.g. Qt's debug console (currently not implemented) or future RPC mechanisms people may want to use. - *HTTP dispatch mechanism*; services (e.g., RPC, REST) register which URL paths they want to handle. By using a proven, high-performance asynchronous networking library (also used by Tor) and HTTP server, problems such as #5674, #5655, #344 should be avoided.

net: Automatically create hidden service, listen on Tor Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket API, to create and destroy 'ephemeral' hidden services programmatically. https://stem.torproject.org/api/control.html#stem.control.Controller.create_ephemeral_hidden_service This means that if Tor is running (and proper authorization is available), bitcoin automatically creates a hidden service to listen on, without user manual configuration. This will positively affect the number of available .onion nodes. - When the node is started, connect to Tor through control socket - Send `ADD_ONION` command - First time: - Make it create a hidden service key - Save the key in the data directory for later usage - Make it redirect port 8333 to the local port 8333 (or whatever port we're listening on). - Keep control socket connection open for as long node is running. The hidden service will (by default) automatically go away when the connection is closed.

estimatefee / estimatepriority RPC methods New RPC methods: return an estimate of the fee (or priority) a transaction needs to be likely to confirm in a given number of blocks. Mike Hearn created the first version of this method for estimating fees. It works as follows: For transactions that took 1 to N (I picked N=25) blocks to confirm, keep N buckets with at most 100 entries in each recording the fees-per-kilobyte paid by those transactions. (separate buckets are kept for transactions that confirmed because they are high-priority) The buckets are filled as blocks are found, and are saved/restored in a new fee_estiamtes.dat file in the data directory. A few variations on Mike's initial scheme: To estimate the fee needed for a transaction to confirm in X buckets, all of the samples in all of the buckets are used and a median of all of the data is used to make the estimate. For example, imagine 25 buckets each containing the full 100 entries. Those 2,500 samples are sorted, and the estimate of the fee needed to confirm in the very next block is the 50'th-highest-fee-entry in that sorted list; the estimate of the fee needed to confirm in the next two blocks is the 150'th-highest-fee-entry, etc. That algorithm has the nice property that estimates of how much fee you need to pay to get confirmed in block N will always be greater than or equal to the estimate for block N+1. It would clearly be wrong to say "pay 11 uBTC and you'll get confirmed in 3 blocks, but pay 12 uBTC and it will take LONGER". A single block will not contribute more than 10 entries to any one bucket, so a single miner and a large block cannot overwhelm the estimates.

Improve chainstate/blockindex disk writing policy There are 3 pieces of data that are maintained on disk. The actual block and undo data, the block index (which can refer to positions on disk), and the chainstate (which refers to the best block hash). Earlier, there was no guarantee that blocks were written to disk before block index entries referring to them were written. This commit introduces dirty flags for block index data, and delays writing entries until the actual block data is flushed. With this stricter ordering in writes, it is now safe to not always flush after every block, so there is no need for the IsInitialBlockDownload() check there - instead we just write whenever enough time has passed or the cache size grows too large. Also updating the wallet's best known block is delayed until this is done, otherwise the wallet may end up referring to an unknown block. In addition, only do a write inside the block processing loop if necessary (because of cache size exceeded). Otherwise, move the writing to a point after processing is done, after relaying.

Update key.cpp to use new libsecp256k1 libsecp256k1's API changed, so update key.cpp to use it. Libsecp256k1 now has explicit context objects, which makes it completely thread-safe. In turn, keep an explicit context object in key.cpp, which is explicitly initialized destroyed. This is not really pretty now, but it's more efficient than the static initialized object in key.cpp (which made for example bitcoin-tx slow, as for most of its calls, libsecp256k1 wasn't actually needed). This also brings in the new blinding support in libsecp256k1. By passing in a random seed, temporary variables during the elliptic curve computations are altered, in such a way that if an attacker does not know the blind, observing the internal operations leaks less information about the keys used. This was implemented by Greg Maxwell.

Implement on-the-fly mempool size limitation. After each transaction which is added to mempool, we first call Expire() to remove old transactions, then throwing away the lowest-feerate transactions. After throwing away transactions by feerate, we set the minimum relay fee to the maximum fee transaction-and-dependant-set we removed, plus the default minimum relay fee. After the next block is received, the minimum relay fee is allowed to decrease exponentially. Its halflife defaults to 12 hours, but is decreased to 6 hours if the mempool is smaller than half its maximum size, and 3 hours if the mempool is smaller than a quarter its maximum size. The minimum -maxmempool size is 40*-limitdescendantsize, as it is easy for an attacker to play games with the cheapest -limitdescendantsize transactions. -maxmempool defaults to 300MB. This disables high-priority transaction relay when the min relay fee adjustment is >0 (ie when the mempool is full). When the relay fee adjustment drops below the default minimum relay fee / 2 it is set to 0 (re-enabling priority-based free relay).

This patch adds an option, `-proxyrandomize` (on by default) that randomizes credentials for every outgoing connection, thus creating a new circuit. 2015-03-16 15:29:59 SOCKS5 Sending proxy authentication 3842137544:3256031132

This gives the user full control of how the transaction is sent.

This just adds the option `-walletbroadcast=<0,1>`. Right now these transactions will get the status Status: conflicted, has not been successfully broadcast yet They shouldn't be shown as conflicted at all (`walletconflicts` is empty). This status will go away when the transaction is received through the network.

Add block pruning functionality This adds a -prune=N option to bitcoind, which if set to N>0 will enable block file pruning. When pruning is enabled, block and undo files will be deleted to try to keep total space used by those files to below the prune target (N, in MB) specified by the user, subject to some constraints: - The last 288 blocks on the main chain are always kept (MIN_BLOCKS_TO_KEEP), - N must be at least 550MB (chosen as a value for the target that could reasonably be met, with some assumptions about block sizes, orphan rates, etc; see comment in main.h), - No blocks are pruned until chainActive is at least 100,000 blocks long (on mainnet; defined separately for mainnet, testnet, and regtest in chainparams as nPruneAfterHeight). This unsets NODE_NETWORK if pruning is enabled. Also included is an RPC test for pruning (pruning.py). Thanks to @rdponticelli for earlier work on this feature; this is based in part off that work.

// If we're using -prune with -reindex, then delete block files that will be ignored by the
// reindex. Since reindexing works by starting at block file 0 and looping until a blockfile
Prune: Support noncontiguous block files In some corner cases, it may be possible for recent blocks to end up in the same block file as much older blocks. Previously, the pruning code would stop looking for files to remove upon first encountering a file containing a block that cannot be pruned, now it will keep looking for candidate files until the target is met and all other criteria are satisfied. This can result in a noncontiguous set of block files (by number) on disk, which is fine except for during some reindex corner cases, so make reindex preparation smarter such that we keep the data we can actually use and throw away the rest. This allows pruning to work correctly while downloading any blocks needed during the reindex.

evhttpd implementation - *Replace usage of boost::asio with [libevent2](http://libevent.org/)*. boost::asio is not part of C++11, so unlike other boost there is no forwards-compatibility reason to stick with it. Together with #4738 (convert json_spirit to UniValue), this rids Bitcoin Core of the worst offenders with regard to compile-time slowness. - *Replace spit-and-duct-tape http server with evhttp*. Front-end http handling is handled by libevent, a work queue (with configurable depth and parallelism) is used to handle application requests. - *Wrap HTTP request in C++ class*; this makes the application code mostly HTTP-server-neutral - *Refactor RPC to move all http-specific code to a separate file*. Theoreticaly this can allow building without HTTP server but with another RPC backend, e.g. Qt's debug console (currently not implemented) or future RPC mechanisms people may want to use. - *HTTP dispatch mechanism*; services (e.g., RPC, REST) register which URL paths they want to handle. By using a proven, high-performance asynchronous networking library (also used by Tor) and HTTP server, problems such as #5674, #5655, #344 should be avoided. What works? bitcoind, bitcoin-cli, bitcoin-qt. Unit tests and RPC/REST tests pass. The aim for now is everything but SSL support. Configuration options: - `-rpcthreads`: repurposed as "number of work handler threads". Still defaults to 4. - `-rpcworkqueue`: maximum depth of work queue. When this is reached, new requests will return a 500 Internal Error. - `-rpctimeout`: inactivity time, in seconds, after which to disconnect a client. - `-debug=http`: low-level http activity logging

http: speed up shutdown This continues/fixes #6719. `event_base_loopbreak` was not doing what I expected it to, at least in libevent 2.0.21. What I expected was that it sets a timeout, given that no other pending events it would exit in N seconds. However, what it does was delay the event loop exit with 10 seconds, even if nothing is pending. Solve it in a different way: give the event loop thread time to exit out of itself, and if it doesn't, send loopbreak. This speeds up the RPC tests a lot, each exit incurred a 10 second overhead, with this change there should be no shutdown overhead in the common case and up to two seconds if the event loop is blocking. As a bonus this breaks dependency on boost::thread_group, as the HTTP server minds its own offspring.

Do not use third party services for IP detection. This is a simplified re-do of closed pull #3088. This patch eliminates the privacy and reliability problematic use of centralized web services for discovering the node's addresses for advertisement. The Bitcoin protocol already allows your peers to tell you what IP they think you have, but this data isn't trustworthy since they could lie. So the challenge is using it without creating a DOS vector. To accomplish this we adopt an approach similar to the one used by P2Pool: If we're announcing and don't have a better address discovered (e.g. via UPNP) or configured we just announce to each peer the address that peer told us. Since peers could already replace, forge, or drop our address messages this cannot create a new vulnerability... but if even one of our peers is giving us a good address we'll eventually make a useful advertisement. We also may randomly use the peer-provided address for the daily rebroadcast even if we otherwise have a seemingly routable address, just in case we've been misconfigured (e.g. by UPNP). To avoid privacy problems, we only do these things if discovery is enabled.

net: Automatically create hidden service, listen on Tor Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket API, to create and destroy 'ephemeral' hidden services programmatically. https://stem.torproject.org/api/control.html#stem.control.Controller.create_ephemeral_hidden_service This means that if Tor is running (and proper authorization is available), bitcoin automatically creates a hidden service to listen on, without user manual configuration. This will positively affect the number of available .onion nodes. - When the node is started, connect to Tor through control socket - Send `ADD_ONION` command - First time: - Make it create a hidden service key - Save the key in the data directory for later usage - Make it redirect port 8333 to the local port 8333 (or whatever port we're listening on). - Keep control socket connection open for as long node is running. The hidden service will (by default) automatically go away when the connection is closed.

Implement on-the-fly mempool size limitation. After each transaction which is added to mempool, we first call Expire() to remove old transactions, then throwing away the lowest-feerate transactions. After throwing away transactions by feerate, we set the minimum relay fee to the maximum fee transaction-and-dependant-set we removed, plus the default minimum relay fee. After the next block is received, the minimum relay fee is allowed to decrease exponentially. Its halflife defaults to 12 hours, but is decreased to 6 hours if the mempool is smaller than half its maximum size, and 3 hours if the mempool is smaller than a quarter its maximum size. The minimum -maxmempool size is 40*-limitdescendantsize, as it is easy for an attacker to play games with the cheapest -limitdescendantsize transactions. -maxmempool defaults to 300MB. This disables high-priority transaction relay when the min relay fee adjustment is >0 (ie when the mempool is full). When the relay fee adjustment drops below the default minimum relay fee / 2 it is set to 0 (re-enabling priority-based free relay).

Parallelize script verification * During block verification (when parallelism is requested), script check actions are stored instead of being executed immediately. * After every processed transactions, its signature actions are pushed to a CScriptCheckQueue, which maintains a queue and some synchronization mechanism. * Two or more threads (if enabled) start processing elements from this queue, * When the block connection code is finished processing transactions, it joins the worker pool until the queue is empty. As cs_main is held the entire time, and all verification must be finished before the block continues processing, this does not reach the best possible performance. It is a less drastic change than some more advanced mechanisms (like doing verification out-of-band entirely, and rolling back blocks when a failure is detected). The -par=N flag controls the number of threads (1-16). 0 means auto, and is the default.

Use real number of cores for default -par, ignore virtual cores To determine the default for `-par`, the number of script verification threads, use [boost::thread::physical_concurrency()](http://www.boost.org/doc/libs/1_58_0/doc/html/thread/thread_management.html#thread.thread_management.thread.physical_concurrency) which counts only physical cores, not virtual cores. Virtual cores are roughly a set of cached registers to avoid context switches while threading, they cannot actually perform work, so spawning a verification thread for them could even reduce efficiency and will put undue load on the system. Should fix issue #6358, as well as some other reported system overload issues, especially on Intel processors. The function was only introduced in boost 1.56, so provide a utility function `GetNumCores` to fall back for older Boost versions.

Parallelize script verification * During block verification (when parallelism is requested), script check actions are stored instead of being executed immediately. * After every processed transactions, its signature actions are pushed to a CScriptCheckQueue, which maintains a queue and some synchronization mechanism. * Two or more threads (if enabled) start processing elements from this queue, * When the block connection code is finished processing transactions, it joins the worker pool until the queue is empty. As cs_main is held the entire time, and all verification must be finished before the block continues processing, this does not reach the best possible performance. It is a less drastic change than some more advanced mechanisms (like doing verification out-of-band entirely, and rolling back blocks when a failure is detected). The -par=N flag controls the number of threads (1-16). 0 means auto, and is the default.

This unsets NODE_NETWORK if pruning is enabled. Also included is an RPC test for pruning (pruning.py). Thanks to @rdponticelli for earlier work on this feature; this is based in part off that work.

It was possible for smartfee to produce a fee below minRelayTxFee which would just result in the transaction getting stuck because it can't be relayed. This also introduces a maxtxfee option which sets an absolute maximum for any fee created by the wallet, with an intention of increasing user confidence that the automatic fees won't burn them. This was frequently a concern even before smartfees. If the configured fee policy won't even allow the wallet to meet the relay fee the transaction creation may be aborted.

In turn, keep an explicit context object in key.cpp, which is explicitly initialized destroyed. This is not really pretty now, but it's more efficient than the static initialized object in key.cpp (which made for example bitcoin-tx slow, as for most of its calls, libsecp256k1 wasn't actually needed). This also brings in the new blinding support in libsecp256k1. By passing in a random seed, temporary variables during the elliptic curve computations are altered, in such a way that if an attacker does not know the blind, observing the internal operations leaks less information about the keys used. This was implemented by Greg Maxwell.

key.cpp: fail with a friendlier message on missing ssl EC support Previously if bitcoind is linked with an OpenSSL which is compiled without EC support, this is seen as an assertion failure "pKey != NULL" at key.cpp:134, which occurs after several seconds. It is an esoteric piece of knowledge to interpret this as "oops, I linked with the wrong OpenSSL", and because of the delay it may not even be noticed. The new output is : OpenSSL appears to lack support for elliptic curve cryptography. For more information, visit https://en.bitcoin.it/wiki/OpenSSL_and_EC_Libraries : Initialization sanity check failed. Bitcoin Core is shutting down. which occurs immediately after attempted startup. This also blocks in an InitSanityCheck() function which currently only checks for EC support but should eventually do more. See #4081.

Together with #4738 (convert json_spirit to UniValue), this rids Bitcoin Core of the worst offenders with regard to compile-time slowness. - *Replace spit-and-duct-tape http server with evhttp*. Front-end http handling is handled by libevent, a work queue (with configurable depth and parallelism) is used to handle application requests. - *Wrap HTTP request in C++ class*; this makes the application code mostly HTTP-server-neutral - *Refactor RPC to move all http-specific code to a separate file*. Theoreticaly this can allow building without HTTP server but with another RPC backend, e.g. Qt's debug console (currently not implemented) or future RPC mechanisms people may want to use. - *HTTP dispatch mechanism*; services (e.g., RPC, REST) register which URL paths they want to handle. By using a proven, high-performance asynchronous networking library (also used by Tor) and HTTP server, problems such as #5674, #5655, #344 should be avoided. What works? bitcoind, bitcoin-cli, bitcoin-qt. Unit tests and RPC/REST tests pass. The aim for now is everything but SSL support. Configuration options: - `-rpcthreads`: repurposed as "number of work handler threads". Still defaults to 4. - `-rpcworkqueue`: maximum depth of work queue. When this is reached, new requests will return a 500 Internal Error. - `-rpctimeout`: inactivity time, in seconds, after which to disconnect a client. - `-debug=http`: low-level http activity logging

Introduce a CChainParameters singleton class and regtest mode. The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

Introduce whitelisted peers. 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).

Make -proxy set all network types, avoiding a connect leak. Previously -proxy was not setting the proxy for IsLimited networks, so if you set your configuration to be onlynet=tor you wouldn't get an IPv4 proxy set. The payment protocol gets its proxy configuration from the IPv4 proxy, and so it would experience a connection leak. This addresses issue #5355 and also clears up a cosmetic bug where getinfo proxy output shows nothing when onlynet=tor is set.

Introduce whitelisted peers. 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).

Add block pruning functionality This adds a -prune=N option to bitcoind, which if set to N>0 will enable block file pruning. When pruning is enabled, block and undo files will be deleted to try to keep total space used by those files to below the prune target (N, in MB) specified by the user, subject to some constraints: - The last 288 blocks on the main chain are always kept (MIN_BLOCKS_TO_KEEP), - N must be at least 550MB (chosen as a value for the target that could reasonably be met, with some assumptions about block sizes, orphan rates, etc; see comment in main.h), - No blocks are pruned until chainActive is at least 100,000 blocks long (on mainnet; defined separately for mainnet, testnet, and regtest in chainparams as nPruneAfterHeight). This unsets NODE_NETWORK if pruning is enabled. Also included is an RPC test for pruning (pruning.py). Thanks to @rdponticelli for earlier work on this feature; this is based in part off that work.

Prune: Support noncontiguous block files In some corner cases, it may be possible for recent blocks to end up in the same block file as much older blocks. Previously, the pruning code would stop looking for files to remove upon first encountering a file containing a block that cannot be pruned, now it will keep looking for candidate files until the target is met and all other criteria are satisfied. This can result in a noncontiguous set of block files (by number) on disk, which is fine except for during some reindex corner cases, so make reindex preparation smarter such that we keep the data we can actually use and throw away the rest. This allows pruning to work correctly while downloading any blocks needed during the reindex.

Initialize database before checking changed txindex In case no database exists yet, and -txindex(=1) is passed, we currently first check whether fTxIndex differs from -txindex (and ask the user to reindex in that case), and only afterwards initialize the database. By swapping these around (the initialization is a no-op in case the database already exists), we allow it to be born in txindex mode, without warning. That also means we don't need to check -reindex anymore, as the wiping/reinit of the databases happens before checking.

New database check routine -checklevel gets a new meaning: 0: verify blocks can be read from disk (like before) 1: verify (contextless) block validity (like before) 2: verify undo files can be read and have good checksums 3: verify coin database is consistent with the last few blocks (close to level 6 before) 4: verify all validity rules of the last few blocks Level 3 is the new default, as it's reasonably fast. As level 3 and 4 are implemented using an in-memory rollback of the database, they are limited to as many blocks as possible without exceeding the limits set by -dbcache. The default of -dbcache=25 allows for some 150-200 blocks to be rolled back. In case an error is found, the application quits with a message instructing the user to restart with -reindex. Better instructions, and automatic recovery (when possible) or automatic reindexing are left as future work.

estimatefee / estimatepriority RPC methods New RPC methods: return an estimate of the fee (or priority) a transaction needs to be likely to confirm in a given number of blocks. Mike Hearn created the first version of this method for estimating fees. It works as follows: For transactions that took 1 to N (I picked N=25) blocks to confirm, keep N buckets with at most 100 entries in each recording the fees-per-kilobyte paid by those transactions. (separate buckets are kept for transactions that confirmed because they are high-priority) The buckets are filled as blocks are found, and are saved/restored in a new fee_estiamtes.dat file in the data directory. A few variations on Mike's initial scheme: To estimate the fee needed for a transaction to confirm in X buckets, all of the samples in all of the buckets are used and a median of all of the data is used to make the estimate. For example, imagine 25 buckets each containing the full 100 entries. Those 2,500 samples are sorted, and the estimate of the fee needed to confirm in the very next block is the 50'th-highest-fee-entry in that sorted list; the estimate of the fee needed to confirm in the next two blocks is the 150'th-highest-fee-entry, etc. That algorithm has the nice property that estimates of how much fee you need to pay to get confirmed in block N will always be greater than or equal to the estimate for block N+1. It would clearly be wrong to say "pay 11 uBTC and you'll get confirmed in 3 blocks, but pay 12 uBTC and it will take LONGER". A single block will not contribute more than 10 entries to any one bucket, so a single miner and a large block cannot overwhelm the estimates.

Handle corrupt wallets gracefully. Corrupt wallets used to cause a DB_RUNRECOVERY uncaught exception and a crash. This commit does three things: 1) Runs a BDB verify early in the startup process, and if there is a low-level problem with the database: + Moves the bad wallet.dat to wallet.timestamp.bak + Runs a 'salvage' operation to get key/value pairs, and writes them to a new wallet.dat + Continues with startup. 2) Much more tolerant of serialization errors. All errors in deserialization are reported by tolerated EXCEPT for errors related to reading keypairs or master key records-- those are reported and then shut down, so the user can get help (or recover from a backup). 3) Adds a new -salvagewallet option, which: + Moves the wallet.dat to wallet.timestamp.bak + extracts ONLY keypairs and master keys into a new wallet.dat + soft-sets -rescan, to recreate transaction history This was tested by randomly corrupting testnet wallets using a little python script I wrote (https://gist.github.com/3812689)

Handle corrupt wallets gracefully. Corrupt wallets used to cause a DB_RUNRECOVERY uncaught exception and a crash. This commit does three things: 1) Runs a BDB verify early in the startup process, and if there is a low-level problem with the database: + Moves the bad wallet.dat to wallet.timestamp.bak + Runs a 'salvage' operation to get key/value pairs, and writes them to a new wallet.dat + Continues with startup. 2) Much more tolerant of serialization errors. All errors in deserialization are reported by tolerated EXCEPT for errors related to reading keypairs or master key records-- those are reported and then shut down, so the user can get help (or recover from a backup). 3) Adds a new -salvagewallet option, which: + Moves the wallet.dat to wallet.timestamp.bak + extracts ONLY keypairs and master keys into a new wallet.dat + soft-sets -rescan, to recreate transaction history This was tested by randomly corrupting testnet wallets using a little python script I wrote (https://gist.github.com/3812689)

wallet: make it possible to disable transaction broadcast This is an advanced feature which will disable any kind of automatic transaction broadcasting in the wallet. This gives the user full control of how the transaction is sent. For example they can broadcast new transactions through some other mechanism themselves, after getting the transaction hex through `gettransaction`. This just adds the option `-walletbroadcast=<0,1>`. Right now these transactions will get the status Status: conflicted, has not been successfully broadcast yet They shouldn't be shown as conflicted at all (`walletconflicts` is empty). This status will go away when the transaction is received through the network.

Prepare block connection logic for headers-first. This changes the block processing logic from "try to atomically switch to a new block" to a continuous "(dis)connect a block, aiming for the assumed best chain". This means the smallest atomic operations on the chainstate become individual block connections or disconnections, instead of entire reorganizations. It may mean that we try to reorganize to one block, fail, and rereorganize again to the old block. This is slower, but doesn't require unbounded RAM. It also means that a ConnectBlock which fails may be no longer called from the ProcessBlock which knows which node sent it. To deal with that, a mapBlockSource is kept, and invalid blocks cause asynchronous "reject" messages and banning (if necessary).

net: Automatically create hidden service, listen on Tor Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket API, to create and destroy 'ephemeral' hidden services programmatically. https://stem.torproject.org/api/control.html#stem.control.Controller.create_ephemeral_hidden_service This means that if Tor is running (and proper authorization is available), bitcoin automatically creates a hidden service to listen on, without user manual configuration. This will positively affect the number of available .onion nodes. - When the node is started, connect to Tor through control socket - Send `ADD_ONION` command - First time: - Make it create a hidden service key - Save the key in the data directory for later usage - Make it redirect port 8333 to the local port 8333 (or whatever port we're listening on). - Keep control socket connection open for as long node is running. The hidden service will (by default) automatically go away when the connection is closed.

Alert if it is very likely we are getting a bad chain Create a monitoring task that counts how many blocks have been found in the last four hours. If very few or too many have been found, an alert is triggered. "Very few" and "too many" are set based on a false positive rate of once every fifty years of constant running with constant hashing power, which works out to getting 5 or fewer or 48 or more blocks in four hours (instead of the average of 24). Only one alert per day is triggered, so if you get disconnected from the network (or are being Sybil'ed) -alertnotify will be triggered after 3.5 hours but you won't get another -alertnotify for 24 hours. Tested with a new unit test and by running on the main network with -debug=partitioncheck Run test/test_bitcoin --log_level=message to see the alert messages: WARNING: check your network connection, 3 blocks received in the last 4 hours (24 expected) WARNING: abnormally high number of blocks generated, 60 blocks received in the last 4 hours (24 expected) The -debug=partitioncheck debug.log messages look like: ThreadPartitionCheck : Found 22 blocks in the last 4 hours ThreadPartitionCheck : likelihood: 0.0777702

Use best header chain timestamps to detect partitioning The partition checking code was using chainActive timestamps to detect partitioning; with headers-first syncing, it should use (and with this pull request, does use) pIndexBestHeader timestamps. Fixes issue #6251

Alert if it is very likely we are getting a bad chain Create a monitoring task that counts how many blocks have been found in the last four hours. If very few or too many have been found, an alert is triggered. "Very few" and "too many" are set based on a false positive rate of once every fifty years of constant running with constant hashing power, which works out to getting 5 or fewer or 48 or more blocks in four hours (instead of the average of 24).

Reorder AppInit2 This reorders AppInit2 into 10 sections: 1) basic setup (OS stuff, signal handlers) 2) parameter interactions (softset) 3) interpreting options without side effects (just setting internal variables) 4) application initialization (datadir lock, daemonize, pidfile, log file) 5) network initialization (network params, proxy, binding) 6) load blockchain 7) load wallet 8) import blocks (-loadblock=) 9) load peers 10) start node/rpc threads 11) finished This means invalid configurations will be detected as soon as possible (in particular, before loading the block chain).

Add "warmup mode" for RPC server. Start the RPC server before doing all the (expensive) startup initialisations like loading the block index. Until the node is ready, return all calls immediately with a new error signalling "in warmup" with an appropriate status message (similar to the init message). This is useful for RPC clients to know that the server is there (e. g., they don't have to start it) but not yet available. It is used in Namecoin and Huntercoin already for some time, and there exists a UI hooked onto the RPC interface that actively uses this to its advantage.
