Hervé Beraud 61c460f3f2 Fix compatibility with Python 3.8
We removed compatibility with Python 3.8 once but it was added back to
tested runtimes for 2023.2. Thus we have to make sure the code works
with Python 3.8, which was broken by [1].

Note that pytz is added back to requirmenets.txt and is now required
regardless of the python version. This is a short term solution until
we figure out the way to fix the requirement-check job (or we again
remove python 3.8 support).

Hervé Beraud a326ec5eea Implement zoneinfo support to drop dependency to pytz
Zoneinfo was introduced within python 3.9.

The support of pytz will be removed within RHEL 10 [1].

2023.2 (bobcat) will move our testing runtime to py3.9 and py3.10
so we want to see pytz removed within this series.

tzdata is required at runtime in our gates, because, by default,
zoneinfo uses the system’s time zone data if available; if no system
time zone data is available, the library will fall back to using the
first-party tzdata package available on PyPI. Apparently our gates have no
time zone data available nor tzdata installed by default because we get the
following error without tzdata installed [3]:
`ModuleNotFoundError: No module named 'tzdata'

So I prefer to add tzdata in our requirements to avoid runtime failure
related to time zone and ensure that time zone are always available.

Sofia Enriquez 02037330d8 Fix json to_primitive when using IO OBjects
Currently, using Cinder's backup service with RBD the
backup-create operation gets stuck when logging
('use_json=True' must be set in the config file).

The oslo.log JSONFormatter gets stuck when passing an
RBDVolumeIOWrapper from os-brick. This happens via os-brick's
utils.trace() method which passes a connector containing
{'path': RBDVolumeIOWrapper}.
The oslo.log JSONFormatter format() method calls
oslo_serialization's jsonutils.to_primitive and passes in
this RBDVolumeIOWrapper object.
 
Therefore the to_primitive method eventually calls
RBDVolumeIOWrapper.read(). In order to fix this the current
path avoids mapping io.IOBase objects and fallback the wrapper
RBD volume object.

Ben Nemec 448807a706 Explicitly set default_flow_style to False
In PyYAML 5.1 they changed this default in the library. Because
we weren't explicitly setting it, this broke our unit tests.
Since default_flow_style=False is usually what you want (hence why
PyYAML changed it), let's set it explicitly.

Also note that this was already being set for dump, but not for
dumps. This is also more consistent.

Hervé Beraud 35dae9c288 Introduce a base yaml parser for all openstack components
A lot of openstack components like:
- solum
- tosca-parser
- heat
- murano
- etc...

reimplement theirs own yaml parser for loading and dumping.

These implementations sometimes forgot to use a safe loader
or safe dumper, our implementation use safe by default.

You can deactive safe by passing the argument is_safe to false when
you call oslo_serialization.yamlutils.load or oslo_serialization.yamlutils.dump.

Victor Stinner cdb2f60d26 jsonutils.to_primitive(): add fallback parameter
For example, to_primitive(fallback=repr) can be used to prevent
serialialization error like "ValueError: Circular reference detected"
when using the JSONFormatter of oslo.log.

If fallback is set, it is also used to convert itertools.count(),
"nasty" objects like types, and to handle TypeError.

Use fallback=six.text_type to convert objects to text.

This patch doesn't change the default behaviour.

Ihar Hrachyshka 38ac21b523 Don't iterate through addresses in netaddr.IPNetwork
Currently, to_primitive tries to iterate through all addresses in the
network, because the type doesn't have a special handling that would
short curcuit it, but also has __iter__. This may be detrimental to
performance, up to the point of node crash due to memory exhaustion if
the passed network range is too large (think of 0.0.0.0/0 or even
2001::/64). This behavior also makes it impossible to restore the
original data format (CIDR).

This patch short curcuits the iteration by handling the IPNetwork type
as a special case, same as we do for IPAddress.

ChangBo Guo(gcb) 3727b2d6e0 Explicitly raise ValueError in to_primitive
The problem in the current version of to_primitive function
from jsonutils module is in the situation when the function
doesn't know how to convert an object to primitive. In that
case the function simply returns the same object which causes
the following exception later in json.dumps:
ValueError: Circular reference detected. This exception is not
obvious and is quite misleading. So I think it would be better
to explicitly raise ValueError here.

Stephen Finucane ede68f08d3 Don't raise TypeError for invalid b64
In Python 2, the 'b64decode' function calls the 'binascii.a2b_base64'
function but catches any 'binascii.Error' exceptions raised and raises a
TypeError instead [1]. In Python 3, a 'binascii.Error' error is raised
instead [2]. Rather than forcing users to handle two types of exception,
we can allow them to catch only the 'bisascii.Error'. Python 2 provides
a function that does just this - 'decodestring' - which we can use. Make
it so.

Gevorg Davoian 4fdaeff758 Replace TypeError by ValueError in msgpackutils
There are some differences in the behaviour of json and msgpack
serializers. Msgpack throws TypeError when it doesn't know
how to handle an object. Json throws ValueError instead. Regarding
the fact that serialization should be configurable (in particular,
serializers should have similar behaviour; right now transition from
json to msgpack leads to errors and fails) this patch proposes to
raise ValueError instead of TypeError on failures so that libraries
already using jsonutils would be able to also work with msgpackutils.

Victor Stinner e49e812900 Add utilities for base64
Writing a code using the base64 module (of the Python standard
library) working on Python 2.7 and 3.4 requires many checks on the
input and/or output type:

* base64.b64encode() only accepts byte string: text must be
  explicitly encoded to ASCII
* base64.b64decode() returns bytes: output must be decoded from UTF-8
  when text is expected

This change adds two pairs of encode/decode functions:

* encode_as_bytes(), decode_as_bytes(): always return the result as
  a byte string
* encode_as_text(), decode_as_text(): always return the result as a
  text string

Encode functions accept text: text is encoded to UTF-8 by default,
but the encoding is configurable.

Decode functions accept text: text is decoded from ASCII.

decode_as_text() decodes the result from UTF-8 by default, but again
the encoding is configurable.


The new submodule is called "base64" to be able to replace:

    import base64

with:

    from oslo_serialization import base64

If the base64 module of the stdlib is needed, it can be imported as a
different name. Example:

    import base64 as std_base64


The encoding example:

    if isinstance(text, six.text_type):
       text = text.encode('utf-8')
    text_b64 = base64.b64encode(text)
    text_b64 = text_b64.decode('ascii')

can be replaced with:

    text_b64 = base64.encode_as_text(text)


The decoding example:

    if isinstance(encoded, six.text_type):
       encoded = encoded.decode('ascii')
    text = base64.b64decode(encoded)
    text = text.decode('utf-8')

can be replaced with:

    text = base64.decode_as_text(text)

oon Python 3. In some cases, we always want bytes. For example, a
HTTP body must be bytes. This function avoids an condition call to
.encode() depending on the type or on the Python version.

For example:

    body = jsonutils.dumps(data)
    if isinstance(body, six.text_type):
        body = body.encode('utf-8')

can be replaced with:

    body = jsonutils.dump_as_bytes(data)
