merge-script e8f72aefd2 Merge bitcoin/bitcoin#29877 : tracing: explicitly cast block_connected duration to nanoseconds `cd0edf26c0` tracing: cast block_connected duration to nanoseconds (0xb10c) Pull request description: When the `validation:block_connected` tracepoint was introduced in `8f37f5c2a5`, the connect block duration was passed in microseconds `µs`. By starting to use steady clock in `fabf1cdb20` this changed to nanoseconds `ns`. As the test only checked if the duration value is `> 0` as a plausibility check, this went unnoticed. This was detected this when setting up monitoring for block validation time as part of the Great Consensus Cleanup Revival discussion. This change casts the duration explicitly to nanoseconds, updates the documentation, and adds a check for an upper bound to the tracepoint interface tests. The upper bound is quite lax as mining the block takes much longer than connecting the empty test block. It's however able to detect a duration passed in an incorrect unit (1000x off). A previous version of this PR casted the duration to microseconds `µs` - however, as the last three major releases have had the duration as nanoseconds (and this went unnoticed), we assume that this is the API now and changeing it back to microseconds would break the API again.

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.

MacDeploy

Scripts and notes for Mac builds.

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.

Command Line Tools

Completions

Shell completions for bash and fish.
