fanquake 8625446b4d Merge #17336 : scripts: search for first block file for linearize-data with some block files pruned `317fb96de9` Add search for first blk file with pruned node (Rjected) Pull request description: <!-- * Please remove the following help text before submitting: * Pull requests without a rationale and clear improvement may be closed immediately. --> <!-- Please provide clear motivation for your patch and explain how it improves Bitcoin Core user experience or Bitcoin Core developer experience significantly: * Any test improvements or new tests that improve coverage are always welcome. * All other changes should have accompanying unit tests (see `src/test/`) or functional tests (see `test/`). Contributors should note which tests cover modified code. If no tests exist for a region of modified code, new tests should accompany the change. * Bug fixes are most welcome when they come with steps to reproduce or an explanation of the potential issue as well as reasoning for the way the bug was fixed. * Features are welcome, but might be rejected due to design or scope issues. If a feature is based on a lot of dependencies, contributors should first consider building the system outside of Bitcoin Core, if possible. * Refactoring changes are only accepted if they are required for a feature or bug fix or otherwise improve developer experience significantly. For example, most "code style" refactoring changes require a thorough explanation why they are useful, what downsides they have and why they significantly improve developer experience or avoid serious programming bugs. Note that code style is often a subjective matter. Unless they are explicitly mentioned to be preferred in the [developer notes](/doc/developer-notes.md), stylistic code changes are usually rejected. --> When bitcoind is running in pruned mode, producing a hashlist with `./linearize-hashes.py linearize.cfg > hashlist.txt` and then executing `linearize-data.py linearize.cfg` will produce: ``` Read 313001 hashes Input file /home/dan/.bitcoin/blocks/blk00000.dat Premature end of block data ``` This happens because `linearize-data` starts by attempting to process `blk00000.dat` regardless of whether or not `blk00000.dat` actually exists - this may not be the case if working with a pruned node. This PR adds a function which finds the first block file that does exist, and calls that function when the `BlockDataCopier` is initialized. This is a refactor of #16431. <!-- Bitcoin Core has a thorough review process and even the most trivial change needs to pass a lot of eyes and requires non-zero or even substantial time effort to review. There is a huge lack of active reviewers on the project, so patches often sit for a long time. --> ACKs for top commit: darosior: ACK `317fb96de9` laanwj: Code review ACK `317fb96de9` theStack: Code review ACK `317fb96de9` Tree-SHA512: fc8014282df6cfe7b267e64db8ce7d82b86b758c302fbfea4a3c39b62d93512f5c2e31a0de4e9c5ec18fc0268c917f011257d37b45afaef6033eec90e4aa585f		5 years ago

Repository Tools

Developer tools

Specific tools for developers working on this repository. Additional tools, including the github-merge.py script, are available in the maintainer-tools repository.

Verify-Commits

Tool to verify that every merge commit was signed by a developer using the github-merge.py script.

Linearize

Construct a linear, no-fork, best version of the blockchain.

A Linux bash script that will set up traffic control (tc) to limit the outgoing bandwidth for connections to the Bitcoin network. This means one can have an always-on bitcoind instance running, and another local bitcoind/bitcoin-qt instance which connects to this node and receives blocks from it.

Seeds

Utility to generate the pnSeed[] array that is compiled into the client.

Build Tools and Keys

Packaging

The Debian subfolder contains the copyright file.

All other packaging related files can be found in the bitcoin-core/packaging repository.

Test and Verify Tools

TestGen

Utilities to generate test vectors for the data-driven Bitcoin tests.

Verify Binaries

This script attempts to download and verify the signature file SHA256SUMS.asc from bitcoin.org.
