Description justinlee5455 2013-05-29 19:58:21 UTC

According to Wikipedia
http://en.wikipedia.org/wiki/Latency_%28engineering%29#Packet-switched_networks
latency means "the time from the source sending a packet to the destination
receiving it". Therefore, latency is unrelated to whether the operation is
asynchronous or synchronous. And also unrelated to whether it's one-way or
round-trip. Latency exists for asynchronous and one-way transfer, because for
current DBus implementations we need at least one context switch to transfer
each message from the sender process to the receiver process. Emphasizing
D-Bus is low-latency could encourage user to abuse/misuse the system.

Patch for D-Bus spec.

Comment 2 Simon McVittie 2013-05-30 11:36:29 UTC

Reassigning to dbus/core. The dbus/doc component in Bugzilla is a trap, unfortunately; it was intended for a (now-dead) project to standardize Telepathy-style documentation annotations in the introspection format, and it doesn't send bugmail to anyone who's still active on D-Bus. I should ask the fd.o sysadmins to delete that component.

This looks fine to me. It will need maintainer consensus (or at least no objections for a while).

Comment 4 Simon McVittie 2013-09-13 13:17:18 UTC

Nobody has objected, so I pushed this. Will be fixed in spec 0.22, dbus 1.7.6.
