Stu Hood commented on ZOOKEEPER-44:
-----------------------------------
I'd be fine with the sort being removed from getChildren, but fixing the
natural sorting problem is still important. It causes undue pain for the client
to have to perform an integer-aware sort to get the proper ordering for locks.
My workaround was to pad the sequence value before appending it to the path in
create:
{code:java}
if ((createRequest.getFlags() & CreateFlags.SEQUENCE) != 0) {
path = path + String.format("%1$010d", parentCVersion);
}
{code}
> DataTree does not use natural sort for getChildren

> Project: Zookeeper
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.0.0
> Reporter: Stu Hood
> Priority: Minor
>
> DataTree.getChildren() performs Collection.sort() on the list of children
> before returning it, but Java's default comparator for Strings will sort
> 'lock-20' before 'lock-3' for instance.
