make single pass package installs more fault tolerant

Priority: minor Milestone: Bcfg2 0.9.6 Release
Component: bcfg2-client Version:

bcfg2 runs with a large number of package changes take forever if the single pass fails. I think bcfg2 is running the installation program for each single package without regard to dependencies when this happens, and it ends up invoking the installer for some packages twice.

If the single pass parsed the output, threw out any packages that couldn't be installed, and tried again, then it would be a lot faster.

For example, in a recent ubuntu install I ran, bcfg2 installed 1700 packages. Here is the error from the single pass install:

E: Version '30' for 'example-content' was not found
Single Pass Failed

If we could catch that kind of error, it should be a lot faster. bcfg2 would only run apt-get twice instead of 1700 times. That would save about an hour with the startup overhead of apt-get.

The attached uses the apt cache in a more sophisticated manner; the installation of unavailable versions of packages is now suppressed. This won't make it into 0.9.6-final (it is too major of a change to an important piece of code) but it can be dropped into the sources pretty easily, and is queued up for
