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.

This should set -# to be globs that match your 'mainline' branches.
