* Audience: Portfile authors
* Requires: MacPorts >=2.0
== Introduction ==
In order to be a good 'Net citizen, it is worthwhile to minimize the load on other's servers. One simple technique is to specify the `master_sites` parameter as specifically as possible so that the other side does not have to supply redirects in order to serve the file we want. This how-to currently addresses only SourceForge.
== SourceForge ==
Hopefully, the following example, using mediainfo version 0.7.60, will illuminate the process. The SourceForge home page for mediainfo is [[http://mediainfo.sourceforge.net]]. Initially, just specifying `'master_sites sourceforge'` in the portfile under development worked to retrieve the distfile. The log for `'port fetch'` showed:
{{{
DEBUG: Executing org.macports.fetch (mediainfo)
---> MediaInfo_CLI_0.7.60_GNU_FromSource.tar.bz2 doesn't seem to exist in /opt/local/var/macports/distfiles/mediainfo
---> Attempting to fetch MediaInfo_CLI_0.7.60_GNU_FromSource.tar.bz2 from http://iweb.dl.sourceforge.net/mediainfo
}}}
Use 'curl -IL !http://iweb.dl.sourceforge.net/mediainfo/MediaInfo_CLI_0.7.60_GNU_FromSource.tar.bz2' to check for redirects. In this case the output indicated redirects to a final address of:
{{{
Location: http://voxel.dl.sourceforge.net/project/mediainfo/binary/mediainfo/0.7.60/MediaInfo_CLI_0.7.60_GNU_FromSource.tar.bz2
}}}
To improve the `master_sites` parameter, extract the bit: `project/mediainfo/binary/mediainfo/0.7.60` (and replace "0.7.60"--the version number in this case--with ${version}). Thus `'master_sites sourceforge:project/mediainfo/binary/mediainfo/${version}'`.
Pat yourself on the back--you're done!
