====== Transmission ======

===== Dependencies =====

==== Build deb ====

  * Go to http://packages.debian.org/wheezy/transmission-daemon
  * Copy the link to the dsc file from the right hand side
  * use dget to fetch the sources

  dget http://ftp.de.debian.org/debian/pool/main/t/transmission/transmission_2.52-3+nmu1.dsc

  * Update the sources. This uses the debian/watch file to update the sources.

  uscan --verbose

  Note: Currently the watch file (debian/watch) is limited to bz2, however transmission has moved to the xz extension. Modify the url to use the xz extension to get the latest build.

  Note: At this point you probably want to remove the patches in debian/patches/*.patch and update the series file as these patches will probably already exist in the upstream version (and probably no longer apply anyway).

  * Build the dsc file so we can use pbuilder

  debuild -i -us -uc -S



==== libevent ====

  * Use this command to list the package for each version of debian.

  rmadison libevent

  * At the moment libevent from backports is a new enough version so we'll just grab those straight into our repo. We need libevent-dev which depends on all of libevent, so we need those packages too.

  cd /scratch/pbuilder/repo/
  apt-get download libevent-dev=2.0.16-stable-1~bpo60+1
  apt-get download libevent-2.0.5=2.0.16-stable-1~bpo60+1
  apt-get download libevent-core-2.0-5=2.0.16-stable-1~bpo60+1
  

  * Update the repo.

  cd /scratch/pbuilder/repo/
  apt-ftparchive packages . > Packages

  * Note the package version from the Packages file.

  less Packages

  * In our case libevent-2.0-5=2.0.16-stable-1~bpo60+1

===== Build deb =====


  * First check the available versions.

  rmadison transmission

  * To make life easier we'll grab the squeeze package and update it rather than backport a sid package.

  apt-get source transmission=2.03-2

  * Update the sources. This uses the debian/watch file to update the sources.

  uscan --verbose

  * First we need to update the dependencies. Edit debian/control to reflect the new version of libevent from earlier.

  cd transmission-<version>
  vim debian/control

  * Add a changelog entry for the new upstream version. 

  dch -e

  * Build the dsc file so we can use pbuilder

  debuild -i -us -uc -S

  * Jump back up a directory and get pbuilder to build the deb.

  cd ..
  pbuilder-dist wheezy build transmission_<version>.dsc

===== Troubleshooting =====

  * You may need to remove patches that have since been upstreamed when you update the code.
