LGTM, but how do we make sure that query messages still fit in 65 Kb ? |
While zlib provides good compression results for gossip, it's a dependency that had a few important CVEs in the past. Some implementations are reluctant to import it, so we decided to remove it from the specification in lightning/bolts#981 We stop compressing with zlib and only send uncompressed results, while still supporting receiving compressed data. We will remove support for decompression once our monitoring indicates that we stopped receiving compressed data.
The previous calculation was wrong and could lead to messages bigger than 65kB.

Thanks for spotting that, there was indeed an issue! |

We removed support for sending compressed data when it was removed from the spec (see #2244). We meant to remove support for receiving compressed data as well as a follow-up, but it slipped for a long time! There's no reason to keep supporting it now.
