In Github issue #2128, @jvincze84 explained the complexity of using external checks in some advanced setups due to the systematic purge of environment variables, and expressed the desire to preserve the existing environment. During the discussion an agreement was found around having an option to "external-check" to do that and that solution was tested and confirmed to work by user @nyxi. This patch just cleans this up, implements the option as "preserve-env" and documents it. The default behavior does not change, the environment is still purged, unless "preserve-env" is passed. The choice of not using "import-env" instead was made so that we could later use it to name specific variables that have to be imported instead of keeping the whole environment. The patch is simple enough that it could be backported if needed (and was in fact tested on 2.6 first). |
