The `j` in these trace packets was supposed to refer to the fact they are json-formatted. Using json for this is overkill, but that means I'm now torn between wanting to preserve the `j` consistency and the `jTrace` consistency. If this were returning a list of types, using json for that might not be totally unreasonable, and would let us avoid this dilemma :P. ================ Comment at: lldb/docs/lldb-gdb-remote.txt:254 +send packet: jTraceSupportedType +read packet: <trace type>/E<error code>;AAAAAAAAA + ---------------- DavidSpickett wrote: > What is the AAAAA for? That's the extended (textual) error message -- lldb and gdb have independently invented incompatible formats for that (I share a blame it that :/). This style of presentation is consistent with the other jTrace packets, though I am not sure it's that helpful really -- we support the extended error on any response packet and we don't document that always. (Also the error message will only be sent if the client actually signals support for it.) (In fact, when I look at the implementation, I see that it will _never_ send the textual error message.)
