During this period mainly I concentrated on two major tasks. The first task was to revise the class design of pkgAcqDebdelta and pkgAcqArchive so that the code common to both classes are properly isolated to prevent duplication. The main duplications I had was in the constructors and in the QueueNext() methods. Initially, since I wrote the pkgAcqDebdelta class by copying the code of pkgAcqArchive, this duplication occurred. Since that was for the initial implementation, I had the plan to revise the design. But Michael also asked me to complete that task before we move on to the next stage of the implementation. As he pointed out, it improved the readability and the design and will make the maintenance and debug easier. To solve this, I added a new class; pkgAcqIntermediate from which both pkgAcqArchive and pkgAcqDebdelta derived. In the pkgAcqIntermediate class (which is a subclass of pkgAcquire::Item), I put all the common methods.
After finishing that task, I worked on the debdelta suite to add index files for debdeltas. I wrote a python module by using existed code of debdelta suite. It can generate an index file for a set of deltas including the fields; Package, SourceVersion, TargetVersion, FileName, Size, MD5sum, SHA1, SHA256. Since I have already added support for 'debdelta' fields in the sources.list file in APT, now the remaining work is to complete the update of debdelta indexes and use their data correctly in the upgrade processes. I also started to implement the progress details generation from debdelta by adding the --status-fd option. But, currently I am not working on it since the progress reporting with debdeltas in upgrade processes is not as synchronous as with normal debs since there is an additional parallel step involved with debdeltas to patch them to create debs. These asynchronous progress details can be easily shown in a GUI. But that is difficult in a terminal. Currently, even if my project work has not been fully completed, debdelta integration of APT can be tested without using index files or progress reporting. I would like to continue working on these two tasks and complete the integration as soon as possible, although today is the firm pencils down date.
