9620cb4493assumeutxo: fail early if snapshot block hash doesn't match AssumeUTXO parameters (Sebastian Falbesoner) Pull request description: Right now the `loadtxoutset` RPC call treats literally all files with a minimum size of 40 bytes (=size of metadata) as potential valid snapshot candidates and the waiting loop for seeing the metadata block hash in the headers chain is always entered, e.g.: ``` $ ./src/bitcoin-cli loadtxoutset ~/.vimrc <wait> bitcoind log: ... 2023-10-15T14:55:45Z [snapshot] waiting to see blockheader 626174207465730a7265626d756e207465730a656c62616e65207861746e7973 in headers chain before snapshot activation ... ``` There is no point in doing any further action though if we already know from the start that the UTXO snapshot loading won't be successful. This PR adds an assumeutxo parameter check immediately after the metadata is read in, so we can fail immediately on a mismatch: ``` $ ./src/bitcoin-cli loadtxoutset ~/.vimrc error code: -32603 error message: Unable to load UTXO snapshot, assumeutxo block hash in snapshot metadata not recognized (626174207465730a7265626d756e207465730a656c62616e 65207861746e7973) ``` This way, users who mistakenly try to load files that are not snapshots don't have to wait 10 minutes (=the block header waiting timeout) anymore to get a negative response. If a file is loaded which is a valid snapshot (referencing to an existing block hash), but one which doesn't match the parameters, the feedback is also faster, as we don't have to wait anymore to see the hash in the headers chain before getting an error. This is also partially fixes #28621. ACKs for top commit: maflcko: lgtm ACK9620cb4493ryanofsky: Code review ACK9620cb4493. This should fix an annoyance and bad UX. pablomartin4btc: tACK9620cb4493Tree-SHA512: f88b865e9d46254858e57c024463f389cd9d8760a7cb30c190aa1723a931e159987dfc2263a733825d700fa612e7416691e4d8aab64058f1aeb0a7fa9233ac9c
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.
