Adding the capability to propagate specific error messages from the Coin Selection process to the user. Instead of always returning the general "Insufficient funds" message which is not always accurate to what happened internally. Letting us instruct the user how to proceed under certain circumstances. The following error messages were added: 1) If the selection result exceeds the maximum transaction weight, we now will return: -> "The inputs size exceeds the maximum weight. Please try sending a smaller amount or manually consolidating your wallet's UTXOs". 2) If the user pre-selected inputs and disallowed the automatic coin selection process (no other inputs are allowed), we now will return: -> "The preselected coins total amount does not cover the transaction target. Please allow other inputs to be automatically selected or include more coins manually". 3) The double-counted preset inputs during Coin Selection error will now throw an "internal bug detected" message instead of crashing the node. The essence of this work comes from several comments: 1. https://github.com/bitcoin/bitcoin/pull/26560#discussion_r1037395665 2. https://github.com/bitcoin/bitcoin/pull/25729#discussion_r940619491 3. https://github.com/bitcoin/bitcoin/pull/25269#pullrequestreview-1135240825 4. https://github.com/bitcoin/bitcoin/issues/23144 (which is connected to #24845) ACKs for top commit: ishaanam: crACK 76dc547ee7b05864e7b1b6c55fc0301d47aa3a15 achow101: ACK 76dc547ee7b05864e7b1b6c55fc0301d47aa3a15 aureleoules: ACK 76dc547ee7b05864e7b1b6c55fc0301d47aa3a15 theStack: ACK 76dc547ee7b05864e7b1b6c55fc0301d47aa3a15 🌇 Tree-SHA512: 9de30792d7a5849cae77747aa978e70390b66ee9d082779a56088a024f82e725b0af050e6603aece0ac8229f6d73bc471ba97b4ab69dc7eddf419f5f56ae89a5
Bitcoin Core integration/staging tree
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.
