+
+Otherwise a client could send small packages smaller than
+total-incoming-payload-size but still to break the server

+Subject: [PATCH] Set message size limit in SoupServer rather than
+ SoupWebsocketConnection
+
+We're not sure about the compatibility implications of having a default
+size limit for clients.
+
+Also not sure whether the server limit is actually set appropriately,
+but there is probably very little server usage of
+SoupWebsocketConnection in the wild, so it's not so likely to break
+things.

+Subject: [PATCH 4/4] Add tests for max-incoming-packet-size and
+ max-total-message-size
+
+An even better test would verify that it's possible to send big messages
+containing small packets, but libsoup doesn't offer control over packet
+size, and I don't want to take the time to learn how WebSockets work to
+figure out how to do that manually. Instead, I just check that both
+limits work, for both client and server.
+
+I didn't add deflate variants of these tests because I doubt that would
+add valuable coverage.
+
+Upstream-Status: Backport [https://gitlab.gnome.org/GNOME/libsoup/-/commit/4d00b45b7eebdcfa0706b58e34c40b8a0a16015b]
