Out of interest, what language do you recommend?
Depends on the job -- I'm a huge fan of choosing the right tool for the
job. I just think C++ tries to be jack of all trades and winds up being
master of none.
Drifting slightly back on topic, a lot of the ZFS code (and even more
driver code) I've looked at would be cleaner in C++. As long as a
library has a C linkage public interface, there aren't any compatibility
issues. The rest is FUD.
There is no common C++ ABI.
Not true - http://www.codesourcery.com/public/cxx-abi/abi.html
So you get into compatibility concerns
between code built with different compilers (like Studio vs. g++).
SS is homebrew now, but at some point in the future will switch over to
the Itanium C++ ABI. On linux how many compiler vendors conform to this
ABI? I would say there's enough to call it a defacto standard. Please
realize that with the exception of Windows it's available and commonly
used almost everywhere...
Fail.
There are many many things to dislike about C++ -- you *can* write good
clean code in C++, but almost none of the C++ code I've seen fits that
description.
I could say the same for java, php and lots of other languages.. While I
don't argue if your view is correct or accurate it's just your opinion
biased by your daily requirements (as a kernel developer)
The various side effects, and unexpected memory explosion that occurs
with the "favored" C++ constructs tends to make C++ completely
unsuitable for use in a kernel.
I still have the scars from when Linus tried to experiment with a Linux
kernel in C++. :-) The effort was *very* short lived. Granted C++ has
changed a lot since then, but I think the ways it has changed make it
even more unsuitable for kernel/embedded work.
Ok so C++ is generally suitable for everything outside of kernel and
embedded work ;)
