/*
|
||||
|
||||
Go Builder is a continuous build client for the Go project.
|
||||
It integrates with the Go Dashboard AppEngine application.
|
||||
|
||||
Go Builder is intended to run continuously as a background process.
|
||||
|
||||
It periodically pulls updates from the Go Mercurial repository.
|
||||
|
||||
When a newer revision is found, Go Builder creates a clone of the repository,
|
||||
runs all.bash, and reports build success or failure to the Go Dashboard.
|
||||
|
||||
For a successful build, Go Builder will also run benchmarks
|
||||
(cd $GOROOT/src/pkg; make bench) and send the results to the Go Dashboard.
|
||||
|
||||
For a release revision (a change description that matches "release.YYYY-MM-DD"),
|
||||
Go Builder will create a tar.gz archive of the GOROOT and deliver it to the
|
||||
Go Google Code project's downloads section.
|
||||
|
||||
Usage:
|
||||
|
||||
gobuilder goos-goarch...
|
||||
|
||||
Several goos-goarch combinations can be provided, and the builder will
|
||||
build them in serial.
|
||||
|
||||
Optional flags:
|
||||
|
||||
-dashboard="godashboard.appspot.com": Go Dashboard Host
|
||||
The location of the Go Dashboard application to which Go Builder will
|
||||
report its results.
|
||||
|
||||
-bench: Run benchmarks
|
||||
|
||||
-release: Build and deliver binary release archive
|
||||
|
||||
The key file should be located at $HOME/.gobuilder or, for a builder-specific
|
||||
key, $HOME/.gobuilder-$BUILDER (eg, $HOME/.gobuilder-linux-amd64).
|
||||
|
||||
The build key file is a text file of the format:
|
||||
|
||||
godashboard-key
|
||||
googlecode-username
|
||||
googlecode-password
|
||||
|
||||
If the Google Code credentials are not provided the archival step
|
||||
will be skipped.
