After recently changing .pylintrc (see [1]) we discovered that the presubmit check always checks all the python files when just one python file gets updated. This CL moves all these files one step closer to what the linter wants. Autogenerated with: # Added all the files under pylint control to ~/Desktop/to-reformat cat ~/Desktop/to-reformat | xargs sed -i '1i\\' git cl format --python --full This is part 1 out of 2. The second part will fix function names and will not be automated.

This script builds a GN executable targeting the host machine.
|
|
|
|
It is useful, for example, for mobile devices performance testing where
|
|
it makes sense to build WebRTC for a mobile platform (e.g. Android) but
|
|
part of the test is performed on the host machine (e.g. running an
|
|
executable to analyze a video downloaded from a device).
|
|
|
|
The script has only one (mandatory) option: --executable_name, which is
|
|
the output name of the GN executable. For example, if you have the
|
|
following executable in your out folder:
|
|
|
|
out/Debug/random_exec
|
|
|
|
You will be able to compile the same executable targeting your host machine
|
|
by running:
|
|
|
|
$ python tools_webrtc/executable_host_build.py --executable_name random_exec
|
|
|
|
The generated executable will have the same name as the input executable with
|
|
suffix '_host'.
|
|
|
|
This script should not be used standalone but from GN, through an action:
|
|
|
|
action("random_exec_host") {
|
|
script = "//tools_webrtc/executable_host_build.py"
|
|
outputs = [
|
|
"${root_out_dir}/random_exec_host",
|
|
]
|
|
args = [
|
|
"--executable_name",
|
|
"random_exec",
|
|
]
|
|
}
|
|
|
|
The executable for the host machine will be generated in the GN out directory
|
|
(e.g. out/Debug in the previous example).
