In this commit, we fix a bug that would cause nodes to be unable to parse a given block from the wire. The block would be properly accepted if fed in via other mechanisms. The issue here is that the old checks for the maximum witness size, circa segwit v0 where placed in the wire package _as well_ as the tx engine. This check should only be in the engine, since it's properly gated by other related scrip validation flags. The fix itself is simple: limit witnesses only based on the maximum block size in bytes, or ~4MB.
This changes isDust to IsDust so other golang projects (btcwallet or lnd) can use the precise dust calculation used by btcd.

This commit modifies no behavior and would allow other projects to retrieve the dust limit for a particular output type before the amount of the output is known. This is particularly useful in the Lightning Network for channel negotiation.

Tests all pass for me locally, but it's using an ancient version of Go in the CI since that's what we had checked in at the time. |
