#if defined(HAVE_CONFIG_H)
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.

#include "compat/sanity.h"
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.

/** Used to pass flags to the Bind() function */
allow listening on -bind=address for blocked networks - this allows the client to listen on via -bind specified addresses (e.g. 127.0.0.1), even when a network (IPv4 in that case) was blocked via e.g -onlynet="Tor" - introduce enum BindFlags to avoid passing multiple bools to Bind() - make -bind help text clear we ALWAYS listen on the specified address - remove an unused variable - remove 2 unneeded IsLimited() checks before calling Bind(), which does these checks anyway - usage case: specify -bind=127.0.0.1 -onlynet="Tor" to allow incoming connections to a Tor hidden service, but still don't allow other IPv4 nodes to connect / get connected

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.

// Thread management and startup/shutdown:

// The network-processing threads are all part of a thread group

// A clean exit happens when StartShutdown() or the SIGTERM
// signal handler sets fRequestShutdown, which triggers

// DetectShutdownThread() then exits, which causes AppInit() to

// Note that if running -daemon the parent process returns from AppInit2

// immediately and the parent exits from main().

setgenerate creates multiple blocks in -regtest mode I'm writing some wallet regression tests using -regtest mode, and need to generate an initial multi-hundred-block chain.

This adds two features to setgenerate in -regtest mode: 1) Instead of being interpreted as number of threads to start, the third argument is the number of blocks to generate. 2) setgenerate will not return until the block creation threads have created the requested number of blocks.

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.

Reopen debug.log on SIGHUP The best log rotation method formerly available was to configure logrotate with the copytruncate option. As described in the logrotate documentation, "there is a very small time slice between copying the file and truncating it, so some logging data might be lost". By sending SIGHUP to the server process, one can now reopen the debug log file without losing any data.

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).

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).

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).

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.

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).

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.

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.

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.

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).

Fix that. Also, improve the performance of ActivateBestBlockStep by using the skiplist to only discover a few potential blocks to connect at a time, instead of all blocks forever - as we likely bail out after connecting a single one anyway.

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.

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)

12 years ago
CValidationState state;
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).

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.

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).
