Message:
  • pb: Add in better documentation for setupve, and add documentation for build2ve. Make sure that if we are doing a parallel build we will stop on errors if that option is set. Fix the code for determining which output files were made. The .dsc, .tar.gz, and .changes files are named based on the Source: option in the debian control file. The .deb files can be extracted from there or (as implemented) from the output of dpkg-deb. Verify that all expected files are present. Refactor code to avoid duplicating long filename construction. Fix bug in running in 32bit VE with 64bit host; the setarch command needs to be used to make the child think it is running in a 32 bit environment. Make the use of a key option to ssh optional so that if ssh-agent is in use no key-file is generated. Do *not* set the time in a virtual environment. It is getting it's time from the parent OS and I believe this piece of code was mis-setting the time since the VE thought it was in UTC rather than PST for the parent and so was shifting the clock by many hours. In the script generated in the sub-child, enable set -e if pb_stop_on_error is set so that if the package build fails we don't try to keep going. Having done that, /proc can remain around on failure, so tolerate that state. Fix the documentation on how the date is being set. Invert the loop that makes the bootstrapping project-builder so that we only include each of the .pm files once; if you have installed the pb-modules and have a locally built copy in @INC you could get both copies in the bootstrap version which lead to updating the source not changing the behavior. When getting the ssh-keyfile, if ssh-agent is running, and asked to use it then use it. Tolerate failures on the debsign step -- the key-file can validly not exist. (Eric Anderson)
  • Add a new option pbusesshagent in pb.conf to allow the user to specify whether he wants to use his existing SSH environement and agent, or if he prefers to create a new key pair for building. (Bruno Cornec)

     535The setupve command prepares a virtual environment for use by project builder. In particular it installs project-builder from the packages into the virtual environment. Two sub-steps are necessary:
     536
     537=over 4
     538
     539=item Update $project.pb
     540
     541You need to have a sshhost entry for setupve to work, so add one, even an invalid one, e.g.:
     542
     543 sshhost $project = foo.example.org
     544
     545=item Setup the virtual environment
    536546
    537547 % pb -v -p $project -m debian-6.0-i386 setupve
    538548
    539549If you prefer to install the current SVN version of project builder, you can substitute the setupve option by the sbx2setupv one.
     550
     551=back
     552
     553=head2 build2ve
     554
     555The build2ve command is similar to the build2pkg command in that it will take the sources created by cms2build and turn them into binary packages. The command has two differences. First, it creates the packages in a virtual environment, i.e. the one made by an earlier setupve setup. Second it copies the resulting packages to a repository and builds the repository meta-data needed.
     556
     557Two sub-steps are needed:
     558
     559=over 4
     560
     561=item Update $project.pb
     562
     563You need to have a valid sshdir and sshhost entry for build2ve to work, so add them. Note that you need to be able to ssh from the host you run the command on to the repository host, preferably without needing to type in a password, so using ssh-agent or having a special passwordless project-builder ssh key will make this step easier.
     564
     565 sshhost $project = localhost
     566 sshdir $project = $home/cache-project-builder/repos
     567
     568=item Build the packages and copy them to the repository
     569
     570 % pb -v -p $project -m debian-6.0-i386 build2ve
     571
     572=back
     573
     574*Debugging:* If the build fails (and you did not specify the --no-stop-on-error) option, then the virtual environment and scripts should still be present and configured to build the package. You can run a command like 'sudo setarch i386 chroot $path bash' in order to get into the environment. In your log you should see a command like that. From there you can go into the /home/pb directory as the pb user and run the same style of pb commands as you did when doing build2pkg. This will help you figure out what has gone wrong in the build in the virtual environment.
