0xb10c	53c9fa9e62	tracing: drop block_connected hash.toString() arg ... The tracepoint `validation:block_connected` was introduced in #22006. The first argument was the hash of the connected block as a pointer to a C-like String. The last argument passed the hash of the connected block as a pointer to 32 bytes. The hash was only passed as string to allow `bpftrace` scripts to print the hash. It was (incorrectly) assumed that `bpftrace` cannot hex-format and print the block hash given only the hash as bytes. The block hash can be printed in `bpftrace` by calling `printf("%02x")` for each byte of the hash in an `unroll () {...}`. By starting from the last byte of the hash, it can be printed in big-endian (the block-explorer format). ```C $p = $hash + 31; unroll(32) { $b = *(uint8*)$p; printf("%02x", $b); $p -= 1; } ``` See also: https://github.com/bitcoin/bitcoin/pull/22902#discussion_r705176691 This is a breaking change to the block_connected tracepoint API, however this tracepoint has not yet been included in a release.	3 years ago
