Merge bitcoin/bitcoin#27631: test: avoid sporadic MINIMALDATA failure in feature_taproot.py (fixes #27595)
54877253c8 test: avoid sporadic MINIMALDATA failure in feature_taproot.py (fixes #27595) (Sebastian Falbesoner)

Pull request description:

  The functional test feature_taproot.py fails in some rare cases on the execution of the following `"branched_codesep"` spending script (can be reproduced via `$ ./test/functional/feature_taproot.py --randomseed 9048710178866422833` on master / 137a98c5a2):

  9d85c03620/test/functional/feature_taproot.py (L741)

  The problem occurs if the first data-push (having random content with a random length in the range [0, 510]) has a length of 1 and the single byte has value of [1...16] or [-1]; in this case, the data-push is not minimally encoded by test framework's CScript class (i.e. doesn't use the special op-codes OP_1...OP_16 or OP_1NEGATE) and the script interpreter throws an SCRIPT_ERR_MINIMALDATA error:

  ```
  test_framework.authproxy.JSONRPCException: non-mandatory-script-verify-flag (Data push larger than necessary) (-26)
  ```

  Background: the functional test framework's CScript class translates passed bytes/bytearrays always to data pushes using OP_PUSHx/OP_PUSHDATA{1,2,4} op-codes (see `CScript.__coerce_instance(...)`). E.g. the expression `CScript(bytes([1]))` yields `bytes([OP_PUSH1, 1])` instead of the minimal-encoded `bytes([OP_1])`.

  Fix this by adapting the random-size range to [2,...], i.e. never pass byte-arrays below length two to be pushed.

  Closes #27595.

Bitcoin Core integration/staging tree

https://bitcoincore.org

For an immediately usable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/.

What is Bitcoin Core?

Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions. It also includes a wallet and graphical user interface, which can be optionally built.

Further information about Bitcoin Core is available in the doc folder.

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 (see doc/build-*.md for instructions) and tested, but it is not guaranteed to be completely stable. Tags are created regularly from release branches to indicate new official, stable release versions of Bitcoin Core.

The https://github.com/bitcoin-core/gui repository is used exclusively for the development of the GUI. Its master branch is identical in all monotree repositories. Release branches and tags do not exist, so please do not fork that repository unless it is for development reasons.

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. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py

The CI (Continuous Integration) systems make 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.
