-----------------------------------------
Summary: Google storage provider cannot retrieve "foo/bar"
Key: JCLOUDS-1008
URL: https://issues.apache.org/jira/browse/JCLOUDS-1008
Project: jclouds
Issue Type: Bug
Components: jclouds-core, jclouds-labs-google
Affects Versions: 1.9.1, 1.9.0, 2.0.0
Reporter: Timur Alperovich
The Google cloud storage provider can PUT, but not GET a blob containing "/" in
its name. When attempting to retrieve "foo/bar", _null_ is always returned.
The reason for this behavior is twofold. First, Google expects "/" in the path
parameters to be percent-encoded. Secondly, jclouds-core does not have a way to
express that a specific path parameter should be encoded prior to being added
to the path.
Currently, the rest processor does the following for the endpoint: assemble all
of the tokens together and call {code}urlEncode(){code} on the result. When it
does so, it also skips encoding any "/" characters. If an encoded token is
passed to the processor, it ends up being encoded twice, as the "%" character
is encoded as %25.
jclouds-core should add {code}@Encoded{code} parameter annotation, which would
encode each parameter individually (including any "/" characters) before
assembling the URL. In this case, the consumers of the API must make sure that
they do not need the entire path to be encoded.
I plan to submit a PR to add the annotation and to use it in the
google-cloud-storage provider. When the annotation is not used, endpoints will
be processed as is.
