Bruce J Schuchardt updated GEODE-8963:
--------------------------------------
Issue Type: Improvement (was: Bug)
> separate client/server compatibility from server/server version compatibility
> -----------------------------------------------------------------------------
>
> Key: GEODE-8963
> URL: https://issues.apache.org/jira/browse/GEODE-8963
> Project: Geode
> Issue Type: Improvement
> Components: serialization
> Reporter: Bruce J Schuchardt
> Priority: Major
>
> A client's version is used for deserializing data received from the client
> and for serializing data sent to the client. It is also used to locate the
> map of Commands used to process client requests. Every time we cut a new
> release we bump this version in KnownVersions and create a new map of
> Commands, even though client/server communications protocols rarely change.
> We should have each KnownVersion hold a client/server compatibility number
> that is used to identify clients rather than the KnownVersion's ordinal.
> For instance,
> {code:java}
> public static final KnownVersion GEODE_1_15_0 =
> new KnownVersion("GEODE", "1.15.0", (byte) 1, (byte) 15, (byte) 0,
> (byte) 0,
> /*server/server version*/GEODE_1_15_0_ORDINAL,
> /*client/server version*/GEODE_1_15_0_ORDINAL);
>
> public static final KnownVersion GEODE_1_16_0 =
> new KnownVersion("GEODE", "1.16.0", (byte) 1, (byte) 16, (byte) 0,
> (byte) 0,
> /*server/server version*/GEODE_1_16_0_ORDINAL,
> /*client/server version*/GEODE_1_15_0_ORDINAL);
> public static final KnownVersion GEODE_1_17_0 =
> new KnownVersion("GEODE", "1.17.0", (byte) 1, (byte) 17, (byte) 0,
> (byte) 0,
> /*server/server version*/GEODE_1_17_0_ORDINAL,
> /*client/server version*/GEODE_1_15_0_ORDINAL);
> {code}
> In the above KnownVersions the client/server serialization is known to have
> not changed since v1.15.0 and so there is no need to use a newer KnownVersion
> for clients.
> Client handshake code will need to be changed to use the client/server
> ordinal when identifying clients and servers.
