Syntax warnings with brand new Azure CLI on macOS installed via brew - attempt 2

[joelparkerhenderson]

Describe the bug

Microsoft staff got trigger-happy and closed a bug report without actually verifying it as fixed. This is subpar DX so please see what you all can do to be mutually respectful and mutually committed to success together; for example, allot a day or week to communicate with the person who's reporting the bug.

#30963 (comment)

In this case, the bug that I'm experiencing is still NOT fixed.

Here's the updated info from just now, that shows the problem is still happening.

Is there a different/better command that you all want me to run, in order to reinstall? And/or a way you want the python item at issue to be changed/replaced/upgraded/etc.?

What's the path forward to getting Azure CLI to change from using Python to using a more reliable language, such as C# or Rust?

Sorry for the misleading comment in previous issue.
It's pretty hard for you to verify if it's fixed now. Please wait for the next release.

PS: We only fix /opt/homebrew/Cellar/azure-cli/2.70.0/libexec/lib/python3.12/site-packages/deviceid/deviceid.py:9: SyntaxWarning: invalid escape sequence '\S'. You may see other warnings like /usr/local/Cellar/azure-cli/2.70.0/libexec/lib/python3.12/site-packages/azure/mgmt/batch/models/_models_py3.py:3512: SyntaxWarning: invalid escape sequence '\ '. They lead from other dependencies in CLI.

It's pretty hard for you to verify if it's fixed now. Please wait for the next release.

It turns out it's pretty easy to verify:

1. Try brand new Azure CLI on macOS installed via brew.

2. Run it such as az --version and if there are no syntax warnings, then this bug is fixed.

Waiting for the next release has been many months of problems, for many developers, in many other bug posts.

Is there a roadmap for changing away from bad dependencies in python, and changing to languages with better dependency management such as C# or Rust?

[bebound]

Reinstalling azure-cli won't work since the official package locks the dependency version.

I don't know why you think switching to other language may solve this issue. Language is totally not related to this.

I don't know why you think switching to other language may solve this issue. Language is totally not related to this.

Because the Azure CLI dependency on python is showing that Azure CLI is not compiling and testing all its dependencies. Thus the kinds of errors that I'm seeing and that hundreds more developers are finding every month that these python warning messages are happening.

Better languages, such as C# or Rust, make it easier to compile a single binary, including all dependencies, then test.

Language is totally not related to this.

It turns out language is totally related to this-- in fact this Azure CLI dynamic dependency is one of the key reasons that Microsoft is strongly recommending that Microsoft enterprise customers-- including me-- switch from python to Microsoft C#.

Can your Azure CLI team please ask the Microsoft C# team for help looking at this?
