reprepro with multiple versions support

This git repository hosts a branch for reprepro which adds multiple versions support to it. See Debian bug #570623 for details and updates.

The upstream repository can be found on https://salsa.debian.org/brlink/reprepro

Release Notes

The multiple-versions patch set adds following features:

Add shunit2 based tests (Closes: #857302)
Support multiple versions. (Closes: #570623)
Add the commands move, movesrc, movematched, movefilter
Add Limit and Archive option

How to keep multiple versions

The default behavior of this reprepro is identical to upstream's version. To keep multiple versions of the same package in the archive, you have to set the Limit option to the desired maximum amount (or to 0 for unlimited). See the description in the man page for details.

Database layout changes

The database layout changes from the upstream release to the multiple versions patch set. The difference is as following:

upstream

packages.db maps "package name" to "control file" without duplicates
no packagenames.db

multiple versions

packages.db maps "package name|version" to "control file" without duplicates
packagenames.db maps "package name" to "package name|version" allowing duplicates and duplicates sorted by dpkg --compare-versions descending

The first time the database is opened by reprepro with multiple versions support, the database will be upgraded from the upstream layout to the multiple versions layout. Warning: There is no way back (but could be done with a simple Python script)!

Howto rebase

Rebase the multiple-versions branch on top of the updated upstream master branch and push it to https://salsa.debian.org/bdrung/reprepro/
Refresh the multiple-versions-debian branch by taking the upstream debian branch. Apply patch debian: Switch to dh and Run shunit2 tests on build time. Cherry-pick all commits from multiple-versions. Then apply patch Add trace debugging output, debian: Update changelog and Add README.md describing this git branch.
