From d69fb4d4ac7bcf7d0d84109bba56cf944646fb24 Mon Sep 17 00:00:00 2001 From: Thomas Wolf Date: Tue, 3 Nov 2020 23:33:19 +0100 Subject: Revert "Client-side protocol V2 support for fetching" This reverts commit f802f06e7fd5a98f256b7b7727598491f563bf2f. I had misunderstood how protocol V2 works. This implementation only works if the negotiation during fetch is done in one round. Fixing this is substantial work in BasePackFetchConnection. Basically I think I'd have to change back negotiate to the V0 version, and have a doFetch() that does if protocol V2 doFetchV2() else doFetchV0() with doFetchV0 the old code, and doFetchV2 completely new. Plus there would need to be a HTTP test case requiring several negotiation rounds. This is a couple of days work at least, and I don't know when I will have the time to revisit this. So although the rest of the code is fine I prefer to back this out completely and not leave a only half working implementation in the code for an indeterminate time.
