This is getting a bit more odd the more methods you add to the class. I know I asked before, but I can't remember the answer - why is this a class with a __new__ and not just a function that returns the correct credential type?

To hide the implementations while providing the right surface for documentation and code completion. It could instead hold an instance of the appropriate credential and wrap its methods... #9302

To ensure the new protocol is available? It isn't needed at runtime, so I don't think it's worth requiring. |

I have a concern here: do we expect customer to "async enter" all the credentials in the chain, or should we have a aenter here that loop thourgh all of them and enter them?
Can I see a sample of usage of this one?
There was a problem hiding this comment.
This is what I want to enable:
credential = DefaultAzureCredential()
client = FooServiceClient(credential)
# ... time passes, many useful service requests are authorized ...
credential.close()I think close is the important API. I don't expect anyone to "enter" or "open" a credential. I have aenter doing nothing here because the credential doesn't know which members of its chain will send requests, and transports will open sessions as needed. (At least, our current transport implementations will. Perhaps we should make explicit who's expected to open a transport.)
There was a problem hiding this comment.
If you implement __aenter__/__aexit__ (e.g. you are an async context manager), then you are strongly signalling to users that using async with is general goodness, but you can do the closing yourself if you so see fit.
If we don't want to give an example of intended use with async with, then why is it an async context manager?
There was a problem hiding this comment.
To be consistent with everything else in the SDK that wraps async transport by exposing __aenter__, __aexit__, and close. This PR does add an async with example to the README, and it's okay to use credentials that way. Every other credential's __aenter__ invokes its transport's __aenter__.
The awkwardness for ChainedTokenCredential.__aenter__ is that if it opens sessions for N credentials, N-1 of them may never be used, at some cost dependent on the HTTP client's implementation. These sessions will all be closed by __aexit__, but I thought it unnecessary to open them given that our async transports will do so as needed.
You need it to make pylint happy, right? |
Sure, I as an SDK developer need it to satisfy pylint, but I get it with this PR. Do you think an SDK user might need it? |

I guess this means every release of KV now will need this new azure-identity, be sure to update the setup.py to reflect that
There was a problem hiding this comment.
Assuming you mean KV will need the new azure-core because the async challenge auth policy uses AsyncTokenCredential, this is what @xiangyan99 and I have been discussing. I haven't bumped dependencies because AsyncTokenCredential is only used in type annotations. I think a user combining old azure-core with new azure-keyvault would need to run mypy or pylint on azure-keyvault to see a warning. Is that mistaken, or too sloppy?

Our default async transport (aiohttp) logs an error at program exit when one of its sessions hasn't been closed. Python and asyncio don't provide a good way for a credential to close its own session at exit.
This PR therefore adds the API surface required for users to close sessions themselves: all async credentials define aenter/exit and a close method (closes #8990). It also adds an
AsyncTokenCredentialprotocol (closes #8845) with these methods.
