Hi Vincent, This is the Cassandra user's mailing list. You can engage the Cassandra developers on dev@cassandra.apache.org mailing list. I have bcc'd the user list and added the dev list.
To answer your question, the spec may have drifted and may require a fix. Please feel free to raise a jira and contribute a patch to the documentation. On a side note, why are you implementing your own driver? Thanks, Dinesh On Sun, Aug 11, 2024 at 8:29 AM Vincent Rischmann <vinc...@rischmann.fr> wrote: > Hello, > > this may not be the best place to ask this, feel free to redirect me. > > I'm working on writing a Cassandra client in my spare time and am > currently implementing the framing that has been added in protocol v5. > > I followed the spec available here: > https://github.com/apache/cassandra/blob/trunk/doc/native_protocol_v5.spec#L97 > but I hit an issue regarding the CRC32, when I tried to decode a frame > generated by cqlsh (which I captured using wireshark) I couldn't get the > right checksum. > > After debugging for a while I realized that the CRC32 hash is always > initialized with 4 "magic" bytes: > https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/net/Crc.java#L38-L54 > > Shouldn't this be added to the specification ? >
