Bug Description

Calling `swift upload container_name ../file_name` will create containers "container_name" and "file_name" (idempotently) instead of uploading "file_name" into "container_name"

Note that it can also manifest as upload failures:

vagrant@saio:~/swift$ swift list
vagrant@saio:~/swift$ swift upload test ../swift/tox.ini
Object PUT failed: https://saio/v1/AUTH_test/swift/tox.ini 404 Not Found [first 60 chars of response] b'<html><h1>Not Found</h1><p>The resource could not be found.<' (txn: tx28319613602045248215a-0065bbea04)
vagrant@saio:~/swift$ swift list
test
vagrant@saio:~/swift$ swift list test
vagrant@saio:~/swift$

From looking at the debug output, it seems to be an issue of some path normalization happening between swiftclient and urllib3:

DEBUG:urllib3.connectionpool:https://saio:443 "PUT /v1/AUTH_test/swift/tox.ini HTTP/1.1" 404 70
INFO:swiftclient:REQ: curl -i https://saio/v1/AUTH_test/test/../swift/tox.ini -X PUT -H "x-object-meta-mtime: 1706655423.853881" -H "X-Auth-Token: AUTH_tk4731a83675b948d8a12fe4b183cef571" -H "Content-Length: 5846"

Also note that you can't avoid the normalization by using --object-name:

vagrant@saio:~/swift$ swift upload test tox.ini --object-name 'bad/./././name'
bad/./././name
vagrant@saio:~/swift$ swift list test
bad/name

And trying to escape the name results in using the escaped name:

vagrant@saio:~/swift$ swift upload test tox.ini --object-name 'bad/%2E/%2E/%2E/name'
bad/%2E/%2E/%2E/name
vagrant@saio:~/swift$ swift list test
bad/%2E/%2E/%2E/name
bad/name
