545ff924ab6303ffabd91fdfc4f0a4962daf133c refactor: use string_view for RPC named argument values (stickies-v) 7727603e44f8f674e0fc8389e78047e2b56e6052 refactor: reduce unnecessary complexity in ParseNonRFCJSONValue (stickies-v) 1d02e599012721549d4c20b1b37fcc5ee7b961b6 test: add cases to JSON parsing (stickies-v) Pull request description: Inspired by MarcoFalke's [comment](https://github.com/bitcoin/bitcoin/pull/26506#discussion_r1036149426). Main purpose of this PR is to minimize copying (potentially large) RPC named arguments when calling `.substr()` by using `std::string_view` instead of `std::string`. Furthermore, cleans up the code by removing unnecessary complexity in `ParseNonRFCJSONValue()` (done first to avoid refactoring required to concatenate `string` and `string_view`), updates some naming and adds a few test cases. Should not introduce any behaviour change. ## Questions - ~Was there actually any merit to `ParseNonRFCJSONValue()` surrounding the value with brackets and then parsing it as an array? I don't see it, and the new approach doesn't fail any tests. Still a bit suspicious about it though.~ - Cleared up by https://github.com/bitcoin/bitcoin/pull/26506#pullrequestreview-1211984059 - If there are no objections to 7727603e44f8f674e0fc8389e78047e2b56e6052, I think we should follow up with a PR to rename `ParseNonRFCJSONValue()` to a local `Parse()` helper function (that throws if invalid), remove it from `client.h` and merge the test coverage we currently have on `ParseNonRFCJSONValue()` with the coverage we have on `UniValue::read()`.

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.
