[bug] Workspace crash with configuration pattern

[kevinpoulet]

Describe the bug

Hello,

I’m on Windows 11, using VS 2022 and Python 3.13.5.

This bug seems to be a regression as it worked on 2.19.2 and other versions before and appeared in 2.20.0 but took me some time to trace the root cause. I’m currently on 2.23.0 and it is still present.

In my profile, I am changing the CMake toolchain for all recipes with a given prefix:

[settings]
arch=x86_64
build_type=Release
compiler=msvc
compiler.cppstd=20
compiler.runtime=dynamic
compiler.runtime_type=Release
compiler.version=194
os=Windows
[conf]
acme.*:tools.cmake.cmaketoolchain:generator=Ninja
tools.system.package_manager:mode=install

When used in a workspace with Conan >= 2.20, it produces the error:

ERROR: Traceback (most recent call last):

ERROR:

Removing the recipe selector and keeping only tools.cmake.cmaketoolchain:generator=Ninja makes the error disappear.

How to reproduce it

I have tested acme.*:tools.system.package_manager:mode=install just to check and got the same error, so it seems to be any configuration patterns.

Thanks for the testing and the feedback @kevinpoulet

I have managed to reproduce, and there is a fix in #19327, it will be in next 2.24

Don't forget to comment in #18263 if you want the feature out of incubating, thanks!

[kevinpoulet]

Thanks.

Hadn't seen the workspace tracking issue. Will report success in it once I successfuly port our first workspace to 2.23.
