Merge #15305: [validation] Crash if disconnecting a block fails 
a47df13471 [qa] Test disconnect block failure -> shutdown (Suhas Daftuar)
4433ed0f73 [validation] Crash if disconnecting a block fails (Suhas Daftuar)

Pull request description:

  If we're unable to disconnect a block during normal operation, then that is a
  failure of our local system (such as disk failure) or the chain that we are on
  (eg CVE-2018-17144), but cannot be due to failure of the (more work) chain that
  we're trying to validate.

  We should abort rather than stay on a less work chain.

  Fixes #14341.

ACKs for top commit:

    utACK a47df13471
  TheBlueMatt:
    utACK a47df13471. Didn't bother to review the test in detail, it looked fine. Debated whether invalidateblock should ever crash the node, but *not* crashing in the case of hitting a pruned block (which is the only change here) is clearly better, even if there are other cases I'd argue we should crash in.
  ryanofsky:
    utACK a47df13471. Only change since last review is new comment.
  promag:
    ACK a47df1347, it takes awhile to quit (RPC connection timeouts) but that's unrelated - hope to fix that soon.
  fanquake:
    ACK a47df13471

Bitcoin Core integration/staging tree

https://bitcoincore.org

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 and useful hints for developers can be found in doc/developer-notes.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.
