chroot not transparent in zoo_create()
--------------------------------------
Key: ZOOKEEPER-1027
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1027
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.3.3
Environment: Linux, ZooKeeper 3.3.3, C-client, java 1.6.0_17-b04,
hotspot server vm
Reporter: Thijs Terlouw
I've recently started to use the chroot functionality (introduced in
3.2.0) as part of my connect string.It mostly works as expected, but
there is one case that is unexpected: when I create a path with
zoo_create() I can retrieve the created path. This is very useful when
you set the ZOO_SEQUENCE flag. Unfortunately the returned path
includes the chroot as part of the path. This was unexpected to me: I
expected that the chroot would be totally transparent. The
documentation for zoo_create() says:
"path_buffer : Buffer which will be filled with the path of the new
node (this might be different than the supplied path because of the
ZOO_SEQUENCE flag)."
This gave me the impression that this flag is the only reason the
returned path is different from the created path, but apparently it's
not. Is this a bug or intended behavior?
I workaround this issue now by remembering the chroot in
my wrapper code and after a call to zoo_create() i check if the returned
path starts with the chroot. If it does, I remove it.
My use case is to create a path with a sequence number and then delete
this path later. Unfortunately I cannot delete the path because it has
the chroot prepended to it, and thus it will result in two chroots.
I believe this only affects the create functions.
