[jira] [Updated] (LIBCLOUD-979) libcloud.storage / S3_RGW: cannot
fetch some objects
[ https://issues.apache.org/jira/browse/LIBCLOUD-979?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jack updated LIBCLOUD-979:
--------------------------
Description:
Libcloud cannot handle some legitimates objects
Here is an example, that will explain the issue
Please check this code:
{quote}from libcloud.storage.types import Provider
from libcloud.storage.providers import get_driver
driver = get_driver(Provider.S3_RGW)(key='access_key', secret='secret_key', host='hostname')
print(driver.get_object('tilde', 'file~'))
{quote}
Output:
{quote}~$ ./test.py
Traceback (most recent call last):
File "./test.py", line 8, in <module>
print(driver.get_object('tilde', 'file~'))
File "/tmp/libcloud/libcloud/storage/drivers/s3.py", line 332, in get_object
response = self.connection.request(object_path, method='HEAD')
File "/tmp/libcloud/libcloud/common/base.py", line 637, in request
response = responseCls(**kwargs)
File "/tmp/libcloud/libcloud/common/base.py", line 152, in __init__
message=self.parse_error(),
File "/tmp/libcloud/libcloud/storage/drivers/s3.py", line 96, in parse_error
raise InvalidCredsError(self.body)
libcloud.common.types.InvalidCredsError: ''
{quote}
A tcpdump shows that libcloud tranforms the key from "file~" to "file%7E" (thus, url-encode)
The slight patch below fixes this issue:

Thanks
