NAME
mm - mirror masterSYNOPSIS
mm [flags] [package-files]DESCRIPTION
mm is the mirror master. It runs multiple calls to mirror in parallel and handles locking and minimal retry times.As with mirror, mm is a package written in Perl.
mm presumes that all the package details are stored in a directory called packages. All the packages for a given site must be in a file whose name is the same as that of the site. So in packages/sunsite.org.uk will be all the package details for the host sunsite.org.uk.
OPTIONS
- -t
- Ignore the minimal retry timers.
- -o site:package
- Only mirror the given site:package.
- -debug
- Enable debugging. If this argument is given more than once the debugging level will increase. Currently the maximum useful level is four.
- -s
- Enable status debugging. This will print out the status of any subprocess as it is spawned or as it exits.
CONFIGURATION FILE
- The configuration file is parsed as a series of statements. Blank lines and lines beginning with a hash are ignored. There are are two kinds of statements, controls and site:package details.
Control statements are of the form:
- keyword=value
You can add whitespace around the equals.
Here is a list of the keywords and their values, any defaults are given inside square brackets:
- home
- Directory that mm chdirs to before doing any work. ['']
- max
- Maximum number of mirrors that can be running in parallel at any one time ['6']
- mirror
- This is the way to call mirror. Any occurence of $args, $package or $site is replace with the appropriate entry from the package. Any $pkg is replaced with a version of $package with all characters that cause problems in filenames converted to underscore. The default is: exec ./mirror \$args -p'\$package' packages/\$site > logs/\$site:\$pkg 2>&1 ['']
- cmd
- Run the given command. This can occur multiple times. ['']
- cmdin
- Run the given command and use its output as mm input. This can occur multiple times. ['']
- skip
- Skip the given site:package when it occurs. ['']
In addition to control statements there are also package details. Each package details statement is of the form:
-
site:package min-restart-last-ok min-restart-last-notok mirror-args
The site and package fields are matched against those in the packages. A mirror will only be run to this site:package if the last mirror run was more than min hours out. The min-restart-last-ok limit will be used if the last call to mirror was successful. If the mirror call failed then min-restart-last-notok will be used.
EXAMPLES
Here is a simple mm input file to manage mirroring two packages.
-
home=/public/mirror ftp.cl.cam.ac.uk:JIPS-nrs 20 20 hcrl.open.ac.uk:hcrl-psion 20 20
More usually the auxilly program pkgs_to_mmin will be used to automatically convert the contents of the packages directory into the site:package statements.
-
home=/public/mirror cmdin=./pkgs_to_mmin packages/*
