Problem: vim.uv.os_setenv gets "stuck" per-key. #32550 Caused by the internal `envmap` cache. #7920 :echo $FOO <-- prints nothing :lua vim.uv.os_setenv("FOO", "bar") :echo $FOO <-- prints bar (as expected) :lua vim.uv.os_setenv("FOO", "fizz") :echo $FOO <-- prints bar, still (not expected. Should be "fizz") :lua vim.uv.os_unsetenv("FOO") :echo $FOO <-- prints bar, still (not expected. Should be nothing) :lua vim.uv.os_setenv("FOO", "buzz") :echo $FOO <-- prints bar, still (not expected. Should be "buzz") Solution: - Remove the `envmap` cache. - Callers to `os_getenv` must free the result. - Update all call-sites. - Introduce `os_getenv_noalloc`. - Extend `os_env_exists()` the `nonempty` parameter.
