Goma is a distributed compiler service for open-source projects such as Chromium and Android.
Electron has a deployment of a custom Goma Backend that we make available to
all Electron Maintainers. See the Access section below for details
on authentication. There is also a
cache-only Goma endpoint that will be
used by default if you do not have credentials. Requests to the cache-only
Goma will not hit our cluster, but will read from our cache and should result
in significantly faster build times.
Currently the only supported way to use Goma is to use our Build Tools.
Goma configuration is automatically included when you set up
If you are a maintainer and have access to our cluster, please ensure that you run
e init with
--goma=cluster in order to configure
build-tools to use
the Goma cluster. If you have an existing config, you can just set
in your config file.
Building with Goma
When you are using Goma you can run
ninja with a substantially higher
value than would normally be supported by your machine.
Please do not set a value higher than 200 on Windows or Linux and 50 on macOS. We monitor Goma system usage, and users found to be abusing it with unreasonable concurrency will be de-activated.
ninja -C out/Testing electron -j 200
If you're using
-j values will automatically
be used for you.
If you access http://localhost:8088 on your local machine you can monitor compile jobs as they flow through the goma system.
For security and cost reasons, access to Electron's Goma cluster is currently restricted
to Electron Maintainers. If you want access please head to
Slack and ping
@goma-squad to ask for access. Please be aware that being a
maintainer does not automatically grant access and access is determined on a
case by case basis.
Uptime / Support
We have automated monitoring of our Goma cluster and cache at https://status.notgoma.com
We do not provide support for usage of Goma and any issues raised asking for help / having issues will probably be closed without much reason, we do not have the capacity to handle that kind of support.
