azurecore 1.30.2

Azure Core shared client library for Python
Azure core provides shared exceptions and modules for Python SDK client libraries.
These libraries follow the Azure SDK Design Guidelines for Python .
If you are a client library developer, please reference client library developer reference for more information.
Source code
| Package (Pypi)
| Package (Conda)
| API reference documentation
Getting started
Typically, you will not need to install azure core;
it will be installed when you install one of the client libraries using it.
In case you want to install it explicitly (to implement your own client library, for example),
you can find it here.
Key concepts
Azure Core Library Exceptions
AzureError
AzureError is the base exception for all errors.
class AzureError(Exception):
def __init__(self, message, *args, **kwargs):
self.inner_exception = kwargs.get("error")
self.exc_type, self.exc_value, self.exc_traceback = sys.exc_info()
self.exc_type = self.exc_type.__name__ if self.exc_type else type(self.inner_exception)
self.exc_msg = "{}, {}: {}".format(message, self.exc_type, self.exc_value) # type: ignore
self.message = str(message)
self.continuation_token = kwargs.get("continuation_token")
super(AzureError, self).__init__(self.message, *args)

message is any message (str) to be associated with the exception.
args are any additional args to be included with exception.
kwargs are keyword arguments to include with the exception. Use the keyword error to pass in an internal exception and continuation_token for a token reference to continue an incomplete operation.
The following exceptions inherit from AzureError:
ServiceRequestError
An error occurred while attempt to make a request to the service. No request was sent.
ServiceResponseError
The request was sent, but the client failed to understand the response.
The connection may have timed out. These errors can be retried for idempotent or safe operations.
HttpResponseError
A request was made, and a non-success status code was received from the service.
class HttpResponseError(AzureError):
def __init__(self, message=None, response=None, **kwargs):
self.reason = None
self.response = response
if response:
self.reason = response.reason
self.status_code = response.status_code
self.error = self._parse_odata_body(ODataV4Format, response) # type: Optional[ODataV4Format]
if self.error:
message = str(self.error)
else:
message = message or "Operation returned an invalid status '{}'".format(
self.reason
)

super(HttpResponseError, self).__init__(message=message, **kwargs)

message is the HTTP response error message (optional)
response is the HTTP response (optional).
kwargs are keyword arguments to include with the exception.
The following exceptions inherit from HttpResponseError:
DecodeError
An error raised during response de-serialization.
IncompleteReadError
An error raised if peer closes the connection before we have received the complete message body.
ResourceExistsError
An error response with status code 4xx. This will not be raised directly by the Azure core pipeline.
ResourceNotFoundError
An error response, typically triggered by a 412 response (for update) or 404 (for get/post).
ResourceModifiedError
An error response with status code 4xx, typically 412 Conflict. This will not be raised directly by the Azure core pipeline.
ResourceNotModifiedError
An error response with status code 304. This will not be raised directly by the Azure core pipeline.
ClientAuthenticationError
An error response with status code 4xx. This will not be raised directly by the Azure core pipeline.
TooManyRedirectsError
An error raised when the maximum number of redirect attempts is reached. The maximum amount of redirects can be configured in the RedirectPolicy.
class TooManyRedirectsError(HttpResponseError):
def __init__(self, history, *args, **kwargs):
self.history = history
message = "Reached maximum redirect attempts."
super(TooManyRedirectsError, self).__init__(message, *args, **kwargs)

history is used to document the requests/responses that resulted in redirected requests.
args are any additional args to be included with exception.
kwargs are keyword arguments to include with the exception.
StreamConsumedError
An error thrown if you try to access the stream of azure.core.rest.HttpResponse or azure.core.rest.AsyncHttpResponse once
the response stream has been consumed.
StreamClosedError
An error thrown if you try to access the stream of the azure.core.rest.HttpResponse or azure.core.rest.AsyncHttpResponse once
the response stream has been closed.
ResponseNotReadError
An error thrown if you try to access the content of azure.core.rest.HttpResponse or azure.core.rest.AsyncHttpResponse before
reading in the response's bytes first.
Configurations
When calling the methods, some properties can be configured by passing in as kwargs arguments.

Parameters
Description

headers
The HTTP Request headers.

request_id
The request id to be added into header.

user_agent
If specified, this will be added in front of the user agent string.

logging_enable
Use to enable per operation. Defaults to False.

logger
If specified, it will be used to log information.

response_encoding
The encoding to use if known for this service (will disable auto-detection).

raw_request_hook
Callback function. Will be invoked on request.

raw_response_hook
Callback function. Will be invoked on response.

network_span_namer
A callable to customize the span name.

tracing_attributes
Attributes to set on all created spans.

permit_redirects
Whether the client allows redirects. Defaults to True.

redirect_max
The maximum allowed redirects. Defaults to 30.

retry_total
Total number of retries to allow. Takes precedence over other counts. Default value is 10.

retry_connect
How many connection-related errors to retry on. These are errors raised before the request is sent to the remote server, which we assume has not triggered the server to process the request. Default value is 3.

retry_read
How many times to retry on read errors. These errors are raised after the request was sent to the server, so the request may have side-effects. Default value is 3.

retry_status
How many times to retry on bad status codes. Default value is 3.

retry_backoff_factor
A backoff factor to apply between attempts after the second try (most errors are resolved immediately by a second try without a delay). Retry policy will sleep for: {backoff factor} * (2 ** ({number of total retries} - 1)) seconds. If the backoff_factor is 0.1, then the retry will sleep for [0.0s, 0.2s, 0.4s, ...] between retries. The default value is 0.8.

retry_backoff_max
The maximum back off time. Default value is 120 seconds (2 minutes).

retry_mode
Fixed or exponential delay between attempts, default is Exponential.

timeout
Timeout setting for the operation in seconds, default is 604800s (7 days).

connection_timeout
A single float in seconds for the connection timeout. Defaults to 300 seconds.

read_timeout
A single float in seconds for the read timeout. Defaults to 300 seconds.

connection_verify
SSL certificate verification. Enabled by default. Set to False to disable, alternatively can be set to the path to a CA_BUNDLE file or directory with certificates of trusted CAs.

connection_cert
Client-side certificates. You can specify a local cert to use as client side certificate, as a single file (containing the private key and the certificate) or as a tuple of both files' paths.

proxies
Dictionary mapping protocol or protocol and hostname to the URL of the proxy.

cookies
Dict or CookieJar object to send with the Request.

connection_data_block_size
The block size of data sent over the connection. Defaults to 4096 bytes.

Async transport
The async transport is designed to be opt-in. AioHttp is one of the supported implementations of async transport. It is not installed by default. You need to install it separately.
Shared modules
MatchConditions
MatchConditions is an enum to describe match conditions.
class MatchConditions(Enum):
Unconditionally = 1 # Matches any condition
IfNotModified = 2 # If the target object is not modified. Usually it maps to etag=<specific etag>
IfModified = 3 # Only if the target object is modified. Usually it maps to etag!=<specific etag>
IfPresent = 4 # If the target object exists. Usually it maps to etag='*'
IfMissing = 5 # If the target object does not exist. Usually it maps to etag!='*'

CaseInsensitiveEnumMeta
A metaclass to support case-insensitive enums.
from enum import Enum

from azure.core import CaseInsensitiveEnumMeta

class MyCustomEnum(str, Enum, metaclass=CaseInsensitiveEnumMeta):
FOO = 'foo'
BAR = 'bar'

Null Sentinel Value
A falsy sentinel object which is supposed to be used to specify attributes
with no data. This gets serialized to null on the wire.
from azure.core.serialization import NULL

assert bool(NULL) is False

foo = Foo(
attr=NULL
)
