fd5579a154 Check responses when retrying bodies
Previously, if a Range request came back 200 OK (rather than 206 Partial
Content), we would mangle the response body. This could happen if there
was a middleware that would silently drop Range headers, for example.

Now, if the response does not include a Content-Range header, we will
log a warning and seek to our previous position in the stream. If the
Content-Range header has an unexpected value, we will raise an exception.

5050027610 _RetryBody doesn't need to take explicit etag/content-length
Also, don't try to do int(None) for chunk-encoded responses (like DLOs
that are longer than a single container listing).

4af623bcf1 Retry download of object body
Currently the swift client retries establishing a connection to the server
(by default up to 5 times).  However, when downloading an object, once
the connection has been established and the inital headers have been
returned, no attempt is made to retry.

So, for example, if 99MB of a 100MB object have been downloaded and the
connection is then lost, the download will fail.  This patch changes the
behaviour to re-establish the connection and fetch the remaining bytes
using the 'Range' header to offset.

Data retry is not yet supported if the original request is for a subset
of the object data (ie uses the 'Range' header), or if resp_chunk_size
has not been set.

The object's etag is checked using If-Match to make sure the object data
hasn't changed since the start of the download.

39b1a31d8a Wrap raw iterators to ensure we send entire contents to server
Currently, if you attempt to stream an upload from an iterator, as in

    def data():
        yield 'foo'
        yield ''
        yield 'bar'
    conn.put_object('c', 'o', data())

... requests will faithfully emit a zero-length chunk, ending the
transfer. Swift will then close the connection, possibly (if Connection:
keep-alive was set) after attempting to parse the next chunk as a new
request.

Now, Swift will receive all of the bytes from the iterable, and any
zero-byte chunks will be ignored.

This will be fixed in requests [1], but not until an eventual 3.0.0
release.

df1f4f3e39 swiftclient content-type header
According to help `swift upload -h` you can add a customized request header 'Content-Type'.
But actually it is ignored (cleared and default is used) if subcommand is upload.

Subcommand post works as expected in help.

Bug fix: Use 'Content-Type' from the customized request headers also if
uploading.

head_object and head_container wrapper methods.

Add tests to verify that the headers parameter of Connection
get_container, head_container and head_object methods is passed to the

6b3638ecec enable autodocumentation for utils module; docstring fixes
This commit adds the utils module to those for which Sphinx
automatically generates documentation from docstrings. (Many of the
functions here may be of little interest to users, but
`generate_temp_url`, at least, definitely deserves to be in the
documentation; in this way, this commit can be seen as a spiritual
companion to ca70dd9e.)

Also, a few markup errors and perceived infelicities in existing
docstrings are amended.

Zack M. Davis
5ae4b42392 make ClientException.http_status default to None rather than 0
The extant default of zero is a bit counterintuitive;
insufficiently-careful programmers using swiftclient in their
application might, without carefully reading the source or
documentation, write buggy code based on the assumption that the
`http_status` attribute is absent or defaults to None if ClientException
is raised for reasons other than to indicate an unsuccessful HTTP
request. (However improbable this scenario may seem, the present author
can sadly attest to it having actually happened at least once.)

Just changing the default would break some tests on Python 3, due to the
`500 <= err.http_status <= 599` comparison in Connection's _retry
method (NoneType and int are not orderable in the Python 3.x series);
thus, the case where http_status is None is explicitly folded into a
code branch that logs and reraises (whereas previously it would have
fallen through to an `else` branch where it would be logged and reraised
just the same).

While we're here, we might as well make ClientException's __init__ use
super() (although admittedly the kinds of multiple-inheritance scenarios
in which `super` truly shines seem unlikely to occur here).

52d39bebc1 absolute expiry option for tempURL generation
The `tempurl` subcommand's second positional argument is called
`seconds` and has heretofore interpreted as the number of seconds for
which the tempURL should be valid, counting from the moment of running
the command. This is indeed a common, if not the most common,
use-case. But some users, occasionally, might want to generate a tempURL
that expires at some particular ("absolute") time, rather than a
particular amount of time relative to the moment of happening to run the
command. (One might make an analogy to the way in which Swift's expiring
object support supports an `X-Delete-At` header in addition to
`X-Delete-After`—and it's the former that must be regarded as
ontologically prior.) Thus, this commit adds an `--absolute` optional
argument to the `tempurl` subcommand; if present, the `seconds` argument
will be interpreted as a Unix timestamp of when the tempURL should be
expire, rather than a duration for which the tempURL should be valid
starting from "now".

4b627327c9 Increase httplib._MAXHEADERS to 256.
By default Swift increase the number of max metadata count to 90
and extra header count to 32. That mean we can put 90 metadata to
Account/Container/Object by default, when user put 90 metadata to a
Account, the Account header count is close or more than 100. The
swift client unable to access Account and get an error likes,

('Connection aborted.', HTTPException('got more than 100 headers',))

So the default _MAXHEADERS(100) won't enough.

4b310083df Stop Connection class modifying os_options parameter
When a caller passes an os_options dict to the Connection class
constructor, the constructor may modify the os_options dict,
which can surprise the caller if they re-use the os_options
dict. Specifically the os_options tenant_name and object_storage_url
may be modified, and the changed values would then leak through to a
subsequent Connection constructed using the same os_options dict.

This fix simply constructs a new dict from the supplied os_options.
The patch also adds a test that covers this and also verifies that
a preauth_url passed as a keyword arg to Connection() will take
precedence over any object_storage_url in an os_options parameter.

3cd1faa7af make Connection.get_auth set url and token attributes on self
When a Connection is first __init__ialized (without providing a
preauthurl or preauthtoken), the url and token attributes are None; they
get set (to be reused on future requests) after one of the wrapper
methods internally using _retry (head_account, get_container,
put_object, and similar friends) is called. However, this had not been
the case for get_auth, much to the momentary confusion and
disappointment of programmers using swiftclient who expected to be able
to get the token or storage URL off the Connection object after calling
get_auth (perhaps in order to make an unusual kind of request that
swiftclient doesn't already have a function for). This commit makes
get_auth set the url and token attributes as one might expect.
