From ca63b414da87f7bdb25effffd187d51191a42b3e Mon Sep 17 00:00:00 2001 From: kegsay Date: Fri, 14 Apr 2023 12:32:42 +0100 Subject: [PATCH] Update GMSL: use static Check functions (#3052) Sister PR to https://github.com/matrix-org/gomatrixserverlib/pull/359 A nice side effect is that we don't need to re-parse the events in some cases. --- federationapi/internal/perform.go | 19 ++++++++++------- go.mod | 2 +- go.sum | 6 ++++++ roomserver/api/wrapper.go | 6 +++--- roomserver/internal/input/input_missing.go | 24 ++++++---------------- setup/mscs/msc2836/msc2836.go | 4 ++-- 6 files changed, 30 insertions(+), 31 deletions(-) diff --git a/federationapi/internal/perform.go b/federationapi/internal/perform.go index 08287c692..c580e5275 100644 --- a/federationapi/internal/perform.go +++ b/federationapi/internal/perform.go @@ -256,10 +256,10 @@ func (r *FederationInternalAPI) performJoinUsingServer( // waste the effort. // TODO: Can we expand Check here to return a list of missing auth // events rather than failing one at a time? -
