---------------------------------------
Summary: FileSystem provider createContainerInLocation can
generate folder with invalid permissions
Key: JCLOUDS-1397
URL: https://issues.apache.org/jira/browse/JCLOUDS-1397
Project: jclouds
Issue Type: Bug
Components: jclouds-blobstore
Affects Versions: 2.0.1
Environment: Windows 7 Enterprise SP 1
Java 1.8.0_131
Reporter: Berin Loritsch
I'm using Spring Boot to wrap calls to the blob store in a microservice. I ran
into a problem on a Windows 7 box I was not expecting: the blob container name
was initialized with a directory that had no privileges. With the following
property, we ran into a disparity in how the folders are created:
{code:java}
jclouds.filesystem.basedir=Z:\blob-store{code}
We have some code in our microservice to ensure the blob store container exists
before we attempt to put any blobs in it. Our initialization code has the
following snippet, which should be enough:
{code:java}
if (!blobStore.containerExists(blobContainerName)) {
blobStore.createContainerInLocation(null, blobContainerName);
}{code}
The end result was that the parent folder described by
{{jclouds.filesystem.basedir}} was correct in that the permissions on the
folder were the default as if you called {{File.mkdirs()}} in a standard Java
application (read, update, write, execute for the process's user). However,
the folder with the container name had no permissions (all turned off).
The symptom we had was an Exception thrown by the Filesystem provider because
the blob could not be renamed from the UUID temp file name to the one in
provided by the putBlob() call.
----
Other pertinent facts:
* The machine is in an Enterprise environment where there are global policies
in place for the network. This is probably a contributing factor since I did
not run into this problem on a Windows 10 Professional box in a more relaxed
environment.
* The workaround was to pre-create the directories with the {{File.mkdirs()}}
call.
