| # These are the list of GN files that run exec_script. This whitelist exists |
| # to force additional review for new uses of exec_script, which is strongly |
| # discouraged. |
| # |
| # GYPI_TO_GN |
| # |
| # Some of these entries are for legacy gypi_to_gn calls. We should not be |
| # adding new calls to this script in the build (see //build/gypi_to_gn.py for |
| # detailed advice). The only time you should be editing this list for |
| # gypi_to_gn purposes is when moving an existing call to a different place. |
| # |
| # 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. |
