no way to create sequential nodes with no prefix under a chroot

[igor47]

lets say that i want to create a series of ephemeral nodes that look like this: /test/service/00001, /test/service/00002, etc...

first, i can't set my chroot to /test/service/ :

irb(main):002:0> zk = ZK.new('localhost:2181/test/service/')
ZK::Exceptions::BadArguments: inputs: {:path=>"/test/service/", :ignore=>:no_node}

so, i'll leave out the trailing slash:

zk = ZK.new('localhost:2181/test/service')
irb(main):005:0> zk.create('', :data => 'hi', :mode => :ephemeral_sequential)
=> "0000000001"

however, this node is not under the /test/service dir, it's under /test and is called /test/service00000000001:

[zk: localhost:2181(CONNECTED) 5] ls /test
[service, service0000000001]

the same situation occurs if i try to use '/' as the path:

irb(main):006:0> zk.create('/', :data => 'hi', :mode => :ephemeral_sequential)
=> "0000000002"
[zk: localhost:2181(CONNECTED) 6] ls /test
[service0000000002, service, service0000000001]

i DO get the correct result if i use '/0' as the path, but i'm not sure if this is safe to do; what happens when the sequential id wraps? does it just get another digit?

irb(main):007:0> zk.create('/0', :data => 'hi', :mode => :ephemeral_sequential)
=> "/00000000000"
[zk: localhost:2181(CONNECTED) 8] ls /test/service
[00000000000]

this looks like an upstream bug, since i was able to reproduce it with just the zookeeper gem. no sense looking at it here, so closing in favor of zk-ruby/zookeeper#58
