Xavier Hanin commented on IVY-654:
----------------------------------
I've started working on this issue, trying to implement cache locking to be
able to share a cache among multiple concurrent resolves. The idea is to use
locking only for the repository cache, the resolution cache (which can now be
split thanks to IVY-628 basic implementation) remaining a per process non
sharable cache.
I've not finished my implementation, I still have to lock some more things
(marked as TODO in BasicResolver) Hopefully I will address these problems this
week-end.
As a side effect I' ve worked on the cache implementation and increased the
responsiblities of the cache manager, decreasing those of the resolver. This is
a first step toward the highly requested IVY-399.

> Currently it isn't possible use the same cache from multiple processes. This
> is a problem in some situations, especially for build servers, which have to
> use one cache per process, defeating some of the purpose of the cache. Adding
> an option allowing to use cache locking to ensure the repository cache can be
> used by concurrent build would be a nice improvement.
> To avoid degrading performance of local builds where the cache is not shared,
> this should only be an option.
