Ensure the origin of all variables inherited from the environment is "environment override" if -e is given. Previously only variables that were set in the makefile had this origin. PDS: Most of these changes are from Dmitry but I slightly modified the algorithm: instead of rearranging the way in which MAKEFLAGS is parsed we reset the env_override value to the default before we re-parse MAKEFLAGS, then we set the origin of all env vars to the correct value based on the new setting. * NEWS: Mention the change for backward-compatibility. * src/main.c (main): Ensure MAKEFLAGS is always marked special. (reset_makeflags): Set env_overrides back to default before parsing MAKEFLAGS. (decode_switches): Call reset_env_override() to check for changes. * src/variable.h (reset_env_override): Declare a new function. * src/variable.c (reset_env_override): Go through all env variables and ensure the origin is correct based on env_overrides. (set_env_override): Helper function for the hash. * tests/scripts/functions/foreach: Fix tests. * tests/scripts/functions/let: Ditto. * tests/scripts/functions/origin: Ditto. * tests/scripts/options/dash-e: Add tests. |
