Isn't that just going to give him the latest revision number? How is that
going to help? The issue is that he wants to support the new feature of
just showing the last N log messsages. This improves performance and
usability of the log viewer, especially since you typically care more
about recent log messages. His UI allows you to go get more messages if
The way this worked prior to 1.2 is that he would get the latest revision
X and then retrieve the messages between X and X - 100. This was fast,
but it might only give you 1 message and then the only option was to go
get the rest. Where as now he can show you the last 100 revisions, the
next 100 etc...
The problem is that when you use the new 1.2 feature against a 1.1 server
it is very slow because the client is retrieving all of the messages and
then filtering them to just give what you asked for.
What Stefan is asking for is a way to determine that he is talking to a
1.1 server so that he can fall back to his old technique but still offer
the great new feature for 1.2 users.
