6f53edb395 Acquire cs_main before ATMP call in block_assemble bench (James O'Beirne) Pull request description: Calling `bench_bitcoin` currently fails due to calling ATMP without acquiring cs_main first in the recently added block_assemble bench (https://github.com/bitcoin/bitcoin/pull/13219). ``` $ cat <(uname -a) <(gcc --version) Linux james 4.4.0-119-generic #143+jamesob SMP Mon Apr 16 21:47:24 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 $ ./src/bench/bench_bitcoin WARNING: This is a debug build - may result in slower benchmarks. # Benchmark, evals, iterations, total, min, max, median Assertion failed: lock cs_main not held in validation.cpp:566; locks held: [1] 19323 abort (core dumped) ./src/bench/bench_bitcoin ``` ``` (gdb) bt #0 0x00007fbdc9cf5428 in __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:54 #1 0x00007fbdc9cf702a in __GI_abort () at abort.c:89 #2 0x0000555a19580dc5 in AssertLockHeldInternal (pszName=pszName@entry=0x555a19834549 "cs_main", pszFile=pszFile@entry=0x555a1988a001 "validation.cpp", nLine=nLine@entry=566, cs=cs@entry=0x555a19ba55c0 <cs_main>) at sync.cpp:157 #3 0x0000555a194b395f in AcceptToMemoryPoolWorker (chainparams=..., pool=..., state=..., ptx=std::shared_ptr (count 1, weak 0) 0x555a1bb819b0, pfMissingInputs=pfMissingInputs@entry=0x0, nAcceptTime=1532964079, plTxnReplaced=0x0, bypass_limits=false, nAbsurdFee=@0x7ffcbc1719d8: 0, coins_to_uncache=std::vector of length 0, capacity 0, test_accept=false) at validation.cpp:566 #4 0x0000555a194ba661 in AcceptToMemoryPoolWithTime (chainparams=..., pool=..., state=..., tx=std::shared_ptr (count 1, weak 0) 0x555a1bb819b0, pfMissingInputs=pfMissingInputs@entry=0x0, nAcceptTime=<optimized out>, plTxnReplaced=0x0, bypass_limits=false, nAbsurdFee=0, test_accept=false) at validation.cpp:998 #5 0x0000555a194ba7ce in AcceptToMemoryPool (pool=..., state=..., tx=std::shared_ptr (count 1, weak 0) 0x555a1bb819b0, pfMissingInputs=pfMissingInputs@entry=0x0, plTxnReplaced=plTxnReplaced@entry=0x0, bypass_limits=bypass_limits@entry=false, nAbsurdFee=0, test_accept=false) at validation.cpp:1014 #6 0x0000555a19363fbe in AssembleBlock (state=...) at bench/block_assemble.cpp:102 #7 0x0000555a193654d3 in std::_Function_handler<void (benchmark::State&), void (*)(benchmark::State&)>::_M_invoke(std::_Any_data const&, benchmark::State&) (__functor=..., __args#0=...) at /usr/include/c++/5/functional:1871 #8 0x0000555a193501d7 in std::function<void (benchmark::State&)>::operator()(benchmark::State&) const (this=this@entry=0x555a1ba2cda0, __args#0=...) at /usr/include/c++/5/functional:2267 #9 0x0000555a1934ec4c in benchmark::BenchRunner::RunAll (printer=..., num_evals=5, scaling=<optimized out>, filter=..., is_list_only=false) at bench/bench.cpp:121 #10 0x0000555a1934ade9 in main (argc=<optimized out>, argv=<optimized out>) at bench/bench_bitcoin.cpp:92 ``` Tree-SHA512: fdd7b28ff123ccea7a4f334d53f735d0c0f94aa9cc52520c2dd34dca45d78c691af64efcd32366fc472fedffbd79591d2be2bb3bfc4a5186e8712b6b452d64e3
Bitcoin Core integration/staging tree
What is Bitcoin?
Bitcoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Core is the name of open source software which enables the use of this currency.
For more information, as well as an immediately useable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/, or read the original whitepaper.
License
Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.
Development Process
The master
branch is regularly built and tested, but is not guaranteed to be
completely stable. Tags are created
regularly to indicate new official, stable release versions of Bitcoin Core.
The contribution workflow is described in CONTRIBUTING.md.
Testing
Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.
Automated Testing
Developers are strongly encouraged to write unit tests for new code, and to
submit new unit tests for old code. Unit tests can be compiled and run
(assuming they weren't disabled in configure) with: make check
. Further details on running
and extending unit tests can be found in /src/test/README.md.
There are also regression and integration tests, written
in Python, that are run automatically on the build server.
These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py
The Travis CI system makes sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.
Manual Quality Assurance (QA) Testing
Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.
Translations
Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.
Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.
Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
Translators should also subscribe to the mailing list.
