This whitelist exists # to force additional review for new uses of exec_script, which is strongly # discouraged. # # PLEASE READ # # You should almost never need to add new exec_script calls. exec_script is # slow, especially on Windows, and can cause confusing effects. Although # individually each call isn't slow or necessarily very confusing, at the scale # of our repo things get out of hand quickly. By strongly pushing back on all # additions, we keep the build fast and clean. If you think you need to add a # new call, please consider: # # - Do not use a script to check for the existence of a file or directory to # enable a different mode. Instead, use GN build args to enable or disable # functionality and set options. An example is checking for a file in the # src-internal repo to see if the corresponding src-internal feature should # be enabled. There are several things that can go wrong with this: # # - It's mysterious what causes some things to happen. Although in many cases # such behavior can be conveniently automatic, GN optimizes for explicit # and obvious behavior so people can more easily diagnose problems. # # - The user can't enable a mode for one build and not another. With GN build # args, the user can choose the exact configuration of multiple builds # using one checkout. But implicitly basing flags on the state of the # checkout, this functionality is broken. # # - It's easy to get stale files. If for example the user edits the gclient # to stop checking out src-internal (or any other optional thing), it's # easy to end up with stale files still mysteriously triggering build # conditions that are no longer appropriate (yes, this happens in real # life). # # - Do not use a script to iterate files in a directory (glob): # # - This has the same "stale file" problem as the above discussion. Various # operations can leave untracked files in the source tree which can cause # surprising effects. # # - It becomes impossible to use "git grep" to find where a certain file is # referenced. This operation is very common and people really do get # confused when things aren't listed. # # - It's easy to screw up. One common case is a build-time script that packs # up a directory. The author notices that the script isn't re-run when the # directory is updated, so adds a glob so all the files are listed as # inputs. This seems to work great... until a file is deleted. When a # file is deleted, all the inputs the glob lists will still be up to date # and no command-lines will have been changed. The action will not be # re-run and the build will be broken. It is possible to get this correct # using glob, and it's possible to mess it up without glob, but globs make # this situation much easier to create. if the build always lists the # files and passes them to a script, it will always be correct. exec_script_whitelist = build_dotfile_settings.exec_script_whitelist + angle_dotfile_settings.exec_script_whitelist + [ # Whitelist entries for //build should go into # //build/dotfile_settings.gni instead, so that they can be shared # with other repos.
