I think this information is important for some cases to have it on hand. The example was present in the thread above: https://lists.tarantool.org/pipermail/tarantool-patches/2026-August/030774.html

This patch is not intended to refactor linux sanitizers action, so the existing solution is used.

Only info about available compilers was added:

«Also, the 'setup-sanitizers-macos' action supplied with
the 'list available compilers' commands in one of it's job.
It helps to get the answer to the question:
'Which compiler we can select just now with our current environment?'

The 'setup-sanitizers-linux' build job extended with such commands also.»

The ‘tee -a’ method allows the programmer to see the step’s result of the env definition. It’s used in the ‘setup’, ‘setup-linux’, ‘setup-macos’ actions and some workflows already. I think it’s a good approach to use. Also, there is an empty grep for the ‘>> $GITHUB_ENV’ method in our scripts.

If there are the strong reasons to change it, I think it must be done in all places and in the separate refactoring patch.

The patch doesn’t enable ASAN for Linux, so this part isn’t changed: the ASAN options for Linux is used as is.

The ASAN options for macOS is just a copy of the Linux options with one exception. The detect_leaks was disabled with the explanation in a comment.

The full option investigation and selection in not the main goal of the patch. The patch enables ASAN for macOS and it’s truly enabled for the options selected.

I agree that the actualization of options for both Linux and macOS is a valuable job. I suggest to make a ticket for it.

May be we can use the file to accumulate the options and to update it in a specific steps. I suggest this task to the new ticket ‘ci: actualization of the ASAN options for Linux and macOS’ also.
