13#
14# In general the value for a build arg in the declare_args block should be the
15# default. In some cases, a DEPS-ed in project will want different defaults for
16# being built as part of Chrome vs. being built standalone. In this case, the
17# Chrome defaults should go here. There should be no overrides here for
18# values declared in the main Chrome repository.

20# Important note for defining defaults: This file is executed before the
21# BUILDCONFIG.gn file. That file sets up the global variables like "is_ios".
22# This means that the default_args can not depend on the platform,
23# architecture, or other build parameters. If you really need that, the other
24# repo should define a flag that toggles on a behavior that implements the
25# additional logic required by Chrome to set the variables.

123# These are the list of GN files that run exec_script. This whitelist exists
124# to force additional review for new uses of exec_script, which is strongly
brettwd385ecf2016-04-19 22:53:23[diff] [blame]125# discouraged.
126#
brettwd385ecf2016-04-19 22:53:23[diff] [blame]127# PLEASE READ
128#
129# You should almost never need to add new exec_script calls. exec_script is
130# slow, especially on Windows, and can cause confusing effects. Although
131# individually each call isn't slow or necessarily very confusing, at the scale
132# of our repo things get out of hand quickly. By strongly pushing back on all
133# additions, we keep the build fast and clean. If you think you need to add a
134# new call, please consider:
135#
Wei-Yin Chen (陳威尹)fec2ace2018-08-10 23:31:24[diff] [blame]136# - Do not use a script to check for the existence of a file or directory to
brettwd385ecf2016-04-19 22:53:23[diff] [blame]137# enable a different mode. Instead, use GN build args to enable or disable
138# functionality and set options. An example is checking for a file in the
139# src-internal repo to see if the corresponding src-internal feature should
140# be enabled. There are several things that can go wrong with this:
141#
142# - It's mysterious what causes some things to happen. Although in many cases
143# such behavior can be conveniently automatic, GN optimizes for explicit
144# and obvious behavior so people can more easily diagnose problems.
145#
146# - The user can't enable a mode for one build and not another. With GN build
147# args, the user can choose the exact configuration of multiple builds
148# using one checkout. But implicitly basing flags on the state of the
149# checkout, this functionality is broken.
150#
151# - It's easy to get stale files. If for example the user edits the gclient
152# to stop checking out src-internal (or any other optional thing), it's
153# easy to end up with stale files still mysteriously triggering build
154# conditions that are no longer appropriate (yes, this happens in real
155# life).
156#
157# - Do not use a script to iterate files in a directory (glob):
158#
159# - This has the same "stale file" problem as the above discussion. Various
160# operations can leave untracked files in the source tree which can cause
161# surprising effects.
162#
163# - It becomes impossible to use "git grep" to find where a certain file is
164# referenced. This operation is very common and people really do get
165# confused when things aren't listed.
166#
167# - It's easy to screw up. One common case is a build-time script that packs
168# up a directory. The author notices that the script isn't re-run when the
169# directory is updated, so adds a glob so all the files are listed as
170# inputs. This seems to work great... until a file is deleted. When a
thakis3e861de2016-06-14 14:24:01[diff] [blame]171# file is deleted, all the inputs the glob lists will still be up to date
brettwd385ecf2016-04-19 22:53:23[diff] [blame]172# and no command-lines will have been changed. The action will not be
173# re-run and the build will be broken. It is possible to get this correct
174# using glob, and it's possible to mess it up without glob, but globs make
175# this situation much easier to create. if the build always lists the
176# files and passes them to a script, it will always be correct.
