NAME
mm - mirror master
SYNOPSIS
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/*
