/*
|
||||
|
||||
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 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.
|
||||
|
||||
Command-line options (and defaults):
|
||||
|
||||
-goarch="": $GOARCH
|
||||
-goos="": $GOOS
|
||||
The target architecture and operating system of this build client.
|
||||
|
||||
-goroot="": $GOROOT
|
||||
A persistent Go checkout. Go Builder will periodically run 'hg pull -u'
|
||||
from this location and use it as a source repository when cloning a
|
||||
revision to be built.
|
||||
|
||||
-path="": Build Path
|
||||
The base path in which building, testing, and archival will occur,
|
||||
such as "/tmp/build". This can be considered volatile.
|
||||
|
||||
-keyfile="": Key File
|
||||
The file containing the build key and Google Code credentials.
|
||||
It 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.
|
||||
|
||||
-host="godashboard.appspot.com": Go Dashboard Host
|
||||
The location of the Go Dashboard application to which Go Builder will
|
||||
report its results.
|
||||
|
||||
-pybin="/usr/bin/python": Python Binary
|
||||
-hgbin="/usr/local/bin/hg": Mercurial Binary
|
||||
These name the local Python and Mercurial binaries.
|
||||
(Python is required only to run the Google Code uploader script, found
|
||||
at $GOROOT/misc/dashboard/googlecode_upload.py.)
