mockchain use cases and examples
I’ve mentioned mockchain a few times here. An interaction with averi today on irc pointed out that I should give some examples of how to use it.
Use case #1:
I have a big pile of srpms – I’m pretty sure they all build, but not sure in what order, I want them all built against fedora-16-x86_64.
mockchain fedora-16-x86_64 -l /tmp/myrepo –recurse *.src.rpm
That will produce a dir at /tmp/myrepo which has a config and results dir filled with: resulting pkgs and the logs from the build process in a subdir per package.
Inside the results dir there will be a fedora-16-x86_64 dir which is a yum repository and can be referred to in a yum repo configuration like:
name= my repo I just built with mockchain
It will also try to build each and every package and any failures will be tried again after everything else has been built – and this will continue in a loop until either all the packages are successfully built or the failures are identical on two loops.
Use Case #2:
I have a bunch of src.rpms, I want to build them, one at a time. After each package build I want to rsync my packages up to fedorapeople immediately for everyone to use.
for pkg in ~/pkgs/*.src.rpm
mockchain fedora-16-x86_64 -l /tmp/myrepo $pkg
rsync -avH -e ssh /tmp/myrepo/results/ fedorapeople.org:public_html/myrepo
Use Case #3:
I have some new pkgs I want to build for fedora-16-x86_64. I have a remote repository that contains additional pkgs which provide some of my build dependencies for these new pkgs.
mockchain fedora-16-x86_64 -a http://servername/path/to/my/remote/repo -l /tmp/myrepo -c *.src.rpm
This will give you a repo in /tmp/myrepo/results/fedora-16-x86_64
Just a few examples of how you can use mockchain in your daily operations.
