contrib/continuous: a continuous integration build manager
This is a simple but powerful continuous integration build system for Git. It works by receiving push events from repositories through the post-receive hook, aggregates them on a per-branch basis into a first-come-first-serve build queue, and lets a background build daemon perform builds one at a time.

#!/usr/bin/perl
|
||||
#
|
||||
# A daemon that waits for update events sent by its companion
|
||||
# post-receive-cinotify hook, checks out a new copy of source,
|
||||
# compiles it, and emails the guilty parties if the compile
|
||||
# (and optionally test suite) fails.
|
||||
#
|
||||
# To use this daemon, configure it and run it. It will disconnect
|
||||
# from your terminal and fork into the background. The daemon must
|
||||
# have local filesystem access to the source repositories, as it
|
||||
# uses objects/info/alternates to avoid copying objects.
|
||||
#
|
||||
# Add its companion post-receive-cinotify hook as the post-receive
|
||||
# hook to each repository that the daemon should monitor. Yes, a
|
||||
# single daemon can monitor more than one repository.
|
||||
#
|
||||
# To use multiple daemons on the same system, give them each a
|
||||
# unique queue file and tmpdir.
|
||||
#
|
||||
# Global Config
|
||||
# -------------
|
||||
# Reads from a Git style configuration file. This will be
|
||||
# ~/.gitconfig by default but can be overridden by setting
|
||||
# the GIT_CONFIG_FILE environment variable before starting.
|
||||
#
|
||||
# cidaemon.smtpHost
|
||||
# Hostname of the SMTP server the daemon will send email
|
||||
# through. Defaults to 'localhost'.
|
||||
#
|
||||
# cidaemon.smtpUser
|
||||
# Username to authenticate to the SMTP server as. This
|
||||
# variable is optional; if it is not supplied then no
|
||||
# authentication will be performed.
|
||||
#
|
||||
# cidaemon.smtpPassword
|
||||
# Password to authenticate to the SMTP server as. This
|
||||
# variable is optional. If not supplied but smtpUser was,
|
||||
# the daemon prompts for the password before forking into
|
||||
# the background.
|
||||
#
|
||||
# cidaemon.smtpAuth
|
||||
# Type of authentication to perform with the SMTP server.
|
||||
# If set to 'login' and smtpUser was defined, this will
|
||||
# use the AUTH LOGIN command, which is suitable for use
|
||||
# with at least one version of Microsoft Exchange Server.
|
||||
# If not set the daemon will use whatever auth methods
|
||||
# are supported by your version of Net::SMTP.
|
||||
#
|
||||
# cidaemon.email
|
||||
# Email address that daemon generated emails will be sent
|
||||
# from. This should be a useful email address within your
|
||||
# organization. Required.
|
||||
#
|
||||
# cidaemon.name
|
||||
# Human friendly name that the daemon will send emails as.
|
||||
# Defaults to 'cidaemon'.
|
||||
#
|
||||
# cidaemon.scanDelay
|
||||
# Number of seconds to sleep between polls of the queue file.
|
||||
# Defaults to 60.
|
||||
#
|
||||
# cidaemon.recentCache
|
||||
# Number of recent commit SHA-1s per repository to cache and
|
||||
# skip building if they appear again. This is useful to avoid
|
||||
# rebuilding the same commit multiple times just because it was
|
||||
# pushed into more than one branch. Defaults to 100.
|
||||
#
|
||||
# cidaemon.tmpdir
|
||||
# Scratch directory to create the builds within. The daemon
|
||||
# makes a new subdirectory for each build, then deletes it when
|
||||
# the build has finished. The pid file is also placed here.
|
||||
# Defaults to '/tmp'.
|
||||
#
|
||||
# cidaemon.queue
|
||||
# Path to the queue file that the post-receive-cinotify hook
|
||||
# appends events to. This file is polled by the daemon. It
|
||||
# must not be on an NFS mount (uses flock). Required.
|
||||
#
|
||||
# cidaemon.nocc
|
||||
# Perl regex patterns to match against author and committer
|
||||
# lines. If a pattern matches, that author or committer will
|
||||
# not be notified of a build failure.
|
||||
#
|
||||
# Per Repository Config
|
||||
# ----------------------
|
||||
# Read from the source repository's config file.
|
||||
#
|
||||
# builder.command
|
||||
# Shell command to execute the build. This command must
|
||||
# return 0 on "success" and non-zero on failure. If you
|
||||
# also want to run a test suite, make sure your command
|
||||
# does that too. Required.
|
||||
#
|
||||
# builder.queue
|
||||
# Queue file to notify the cidaemon through. Should match
|
||||
# cidaemon.queue. If not set the hook will not notify the
|
||||
# cidaemon.
|
||||
#
|
||||
# builder.skip
|
||||
# Perl regex patterns of refs that should not be sent to
|
||||
# cidaemon. Updates of these refs will be ignored.
|
||||
#
|
||||
# builder.newBranchBase
|
||||
# Glob patterns of refs that should be used to form the
|
||||
# 'old' revions of a newly created ref. This should set
|
||||
# to be globs that match your 'mainline' branches. This
|
||||
# way a build failure of a brand new topic branch does not
|
||||
# attempt to email everyone since the beginning of time;
|
||||
# instead it only emails those authors of commits not in
|
||||
# these 'mainline' branches.
