c4e77177276ea2b79c4675cb2678ee2cc757b743 refactor: Change LogPrintLevel order to category, severity (laanwj) ce920713bf0810614c2c0c994511b50d4f660bce leveldb: Log messages from leveldb with category and debug level (laanwj) 18ec120bb9e1fc9d27d2419da4c580bd3cde7e86 http: Use severity-based logging for messages from libevent (laanwj) bd971bffb02c7b06aac9a479f7e5ed8f71de2bec logging: Unconditionally log levels >= WARN (laanwj) Pull request description: Log messages from leveldb and libevent libraries in the severity+level based log format introduced in bitcoin/bitcoin#24464. Example of messages before: ``` 2022-05-24T18:11:57Z [libevent] libevent: event_add: event: 0x55da963fcc10 (fd 10), EV_READ call 0x7f1c7a254620 2022-05-24T18:11:57Z [libevent] libevent: Epoll ADD(1) on fd 10 okay.

I think this is useful to make sure warnings and errors, which tend to be important, are not lost. In the future this should be made more configurable. Last commit changes LogPrintLevel argument order to category, severity: This is more consistent with the other functions, as well as with the logging output itself. If we want to make this change, we should do it before it's all over the place.

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.
