Can I run the 1.5 client on a 1.4.3 installation?

[sv...@salvisberg.com]

The 1.5 client has a bug fix that I need. What is the risk of running the 1.5 client on a 1.4.3 installation, as long as I only use 1.4 commands?

TIA,
Hans

Can't we help you by backporting the fix and release it in a next 1.4
release? What fix are you talking about?

If not: assuming you'll replace the libraries on your system with the
1.5-dev ones, all applications should keep working: the libraries are
backward compatible (ie provide all the same entry points as earlier
versions).

When you decide to build applications against 1.5-dev and you update
to a newer 1.5-dev, you run the risk that entry points have their
signatures changed iff they were added in  the 1.5 cycle. That's
basically all.

I must stress however that you'll also get any bugs that have been
introduced since 1.4 and will be fixed before 1.5-final. I hope you're
aware of that risk.

bye,


Erik.

If it's a *bug* fix, maybe you can point out the one you need so we can
check if it's possible to backport it to 1.4.4?

Concerning the risk, well, one of the project's goals is to keep 1.x
clients always compatible with 1.x servers, be it with possible reduced
functionalities. The only risk you're taking is that you're using
work-in-progress, which may contain all sorts of new bugs or broken
functionality.
