3339ba28e9 Make g_enable_bip61 a member variable of PeerLogicValidation (Jesse Cohen) 6690a28606 Restrict as much as possible in net_processing to translation unit (Jesse Cohen) 1d4df02b7e [move-only] Move things only referenced in net_processing out of header file (Jesse Cohen) 02bbc05310 Rescope g_enable_bip61 to net_processing (Jesse Cohen) Pull request description: As part of a larger effort to decouple net_processing and validation a bit, these are a bunch of simple scope cleanups. I've moved things out of the header file that are only referenced in net_processing and added static (or anonymous namespace) modifiers to everything possible in net_processing. There are a handful of functions which could be static except that they are exposed for the sake of unit testing - these are explicitly commented. There has been some discussion of a compile time annotation, but no conclusion has been reached on that yet. This is somewhat related to other prs #12934 #13413 #13407 and will be followed by prs that reduce reliance on cs_main to synchronize data structures which are translation unit local to net_processing Tree-SHA512: 46c9660ee4e06653feb42ba92189565b0aea17aac2375c20747c0d091054c63829cbf66d2daddf65682b58ce1d6922e23aefea051a7f2c8abbb6db253a609082

2018-05-16Merge #13023: Fix some concurrency issues in ActivateBestChain()Wladimir J. van der Laan
dd435ad Add unit tests for signals generated by ProcessNewBlock() (Jesse Cohen) a3ae8e6 Fix concurrency-related bugs in ActivateBestChain (Jesse Cohen) ecc3c4a Do not unlock cs_main in ABC unless we've actually made progress. (Matt Corallo) Pull request description: Originally this PR was just to add tests around concurrency in block validation - those tests seem to have uncovered another bug in ActivateBestChain - this now fixes that bug and adds tests. ActivateBestChain (invoked after a new block is validated) proceeds in steps - acquiring and releasing cs_main while incrementally disconnecting and connecting blocks to sync to the most work chain known (FindMostWorkChain()). Every time cs_main is released the result of FindMostWorkChain() can change - but currently that value is cached across acquisitions of cs_main and only refreshed when an invalid chain is explored. It needs to be refreshed every time cs_main is reacquired. The test added in https://github.com/bitcoin/bitcoin/pull/13023/commits/6094ce73045fe0b4654ff94327c2059512af88fb will occasionally fail without the commit fixing this issue https://github.com/bitcoin/bitcoin/pull/13023/commits/26bfdbaddbb9f13864deb7241c6d513f22c5ab62 Original description below -- After a bug discovered where UpdatedBlockTip() notifications could be triggered out of order (#12978), these unit tests check certain invariants about these signals. The scheduler test asserts that a SingleThreadedSchedulerClient processes callbacks fully and sequentially. The block validation test generates a random chain and calls ProcessNewBlock from multiple threads at random and in parallel. ValidationInterface callbacks verify that the ordering of BlockConnected BlockDisconnected and UpdatedBlockTip events occur as expected.

2018-04-18Consistently log CValidationState on failureBen Woosley
Seems providing at least minimal visibility to the failure is a good practice. The only remaining ignored state is in LoadExternalBlockFile, where logging would likely be spammy.

2018-04-10Merge #12926: Run unit tests in parallelWladimir J. van der Laan
7ef9cd8 Increase entropy in test temp directory name (Pieter Wuille) f6dfb0f Reorder travis builds (Pieter Wuille) 156db42 tests: run tests in parallel (Cory Fields) 66f3255 tests: split up actual tests and helper files (Cory Fields) Pull request description: This runs the unit tests (`src/test/test_bitcoin`) in 4 separate simultaneous processes, significantly speeding up some Travis runs (over 2x for win32). This uses an approach by @theuni that relies on `make` as the mechanism for distributing tests over processes (through `-j`). For every test .cpp file, we search for `BOOST_FIXTURE_TEST_SUITE` or `BOOST_AUTO_TEST_SUITE`, and then invoke the test binary for just that suite (using `-t`). The (verbose) output is stored in a temporary file, and only shown in the case of failure. Some makefile reshuffling is necessary to avoid trying to run tests from `src/test/test_bitcoin.cpp` for example, which contains framework/utility code but no real tests. Finally, order the Travis jobs from slow to fast (apart from the arm/doc job which goes first, for fast failure). This should help reducing the total wall clock time before opening a PR and finishing Travis, in case where not all jobs are started simultaneously. This is an alternative to #12831.

This PR makes a versionbits starttime of -1 equal to "always active", and enables it by default for SegWit on regtest. Individual tests can override this by using the existing `-vbparams` option. A few unit tests and functional tests are adapted to indeed override vbparams, as they specifically test the transition. This is in preparation for wallet SegWit support, but I thought having earlier eyes on it would be useful.

If our tip hasn't updated in a while, that may be because our peers are not relaying blocks to us that we would consider valid. Allow connection to an additional outbound peer in that circumstance. Also, periodically check to see if we are exceeding our target number of outbound peers, and disconnect the one which has least recently announced a new block to us (choosing the newest such peer in the case of tie).

Only create objects as needed. * More clearly document exactly what is and isn't called in -reindex and -reindex-chainstate both with comments noting calls as no-ops and by adding if guards. * Move the writing of fTxIndex to LoadBlockIndex - this fixes a bug introduced in d6af06d68aae985436cbc942f0d11078041d121b where InitBlockIndex was writing to fTxIndex which had not yet been checked (because LoadChainTip hadn't yet initialized the chainActive, which would otherwise have resulted in InitBlockIndex being a NOP), allowing you to modify -txindex without reindex, potentially corrupting your chainstate! * Rename InitBlockIndex to LoadGenesisBlock, which is now a more natural name for it. Also check mapBlockIndex instead of chainActive, fixing a bug where we'd write the genesis block out on every start. * Move LoadGenesisBlock further down in init. This is a more logical location for it, as it is after all of the blockindex-related loading and checking, but before any of the UTXO-related loading and checking. * Give LoadChainTip a return value - allowing it to indicate that the UTXO DB ran ahead of the block DB. This just provides a nicer error message instead of the previous mysterious assert(!setBlockIndexCandidates.empty()) error. * Calls ActivateBestChain in case we just loaded the genesis block in LoadChainTip, avoiding relying on the ActivateBestChain in ThreadImport before continuing init process. * Move all of the VerifyDB()-related stuff into a -reindex + -reindex-chainstate if guard. It couldn't do anything useful as chainActive.Tip() would be null at this point anyway.

2017-06-07Cache full script execution results in addition to signaturesMatt Corallo
This adds a new CuckooCache in validation, caching whether all of a transaction's scripts were valid with a given set of script flags. Unlike previous attempts at caching an entire transaction's validity, which have nearly universally introduced consensus failures, this only caches the validity of a transaction's scriptSigs. As these are pure functions of the transaction and data it commits to, this should be much safer. This is somewhat duplicative with the sigcache, as entries in the new cache will also have several entries in the sigcache. However, the sigcache is kept both as ATMP relies on it and because it prevents malleability-based DoS attacks on the new higher-level cache. Instead, the -sigcachesize option is re-used - cutting the sigcache size in half and using the newly freed memory for the script execution cache. Transactions which match the script execution cache never even have entries in the script check thread's workqueue created. Note that the cache is indexed only on the script execution flags and the transaction's witness hash. While this is sufficient to make the CScriptCheck() calls pure functions, this introduces dependancies on the mempool calculating things such as the PrecomputedTransactionData object, filling the CCoinsViewCache, etc in the exact same way as ConnectBlock. I belive this is a reasonable assumption, but should be noted carefully. In a rather naive benchmark (reindex-chainstate up to block 284k with cuckoocache always returning true for contains(), -assumevalid=0 and a very large dbcache), this connected blocks ~1.7x faster.
