Hi folks, (CC'd to -devel for comments about the database stuff at the end, and also the chroot-* symlinks if anyone still uses them.)
Just to let you know what I'm currently working on, and planning to work on: Completed and current work ========================== 1. Re-addition of sudo support ------------------------------ http://git.debian.org/?p=users/rleigh/sbuild.git;a=shortlog;h=refs/heads/sudo-branch For a few years now, schroot has been used to access chroots, with the older sudo access method deprecated, obsoleted and removed. However, a few people expressed a need for sudo support in order to have behaviour identical to buildd sbuilds, including non-functional networking and having apt and dpkg run outside of the chroot environment. While I didn't have time before the Lenny freeze, it's now got to the top of my ad-hoc TODO list. This mostly involves re-merging already existing (but removed) code back into the current codebase. A split apt/dpkg chroot setup is not possible at the moment, so I've been looking at adding back sudo support to sbuild. With the object-orientation of sbuild over the last year, it's now possible to cleanly abstract this out by deriving sudo- and schroot-specific variants of the Sbuild::Chroot and Sbuild::ChrootInfo classes, special cases being the handling of apt and dpkg runs. The above URL shows the sudo-specific changes I've made over the last day or so. It should be done and finished later on in the week, time permitting. Chroot symlinks: schroot uses system wide chroot definitions in /etc/schroot/schroot.conf and /etc/schroot/chroot.d. sbuild, conversely uses chroot-* symlinks (or directories) in the current build directory. I was thinking of requiring symlinks to the sudo-accessible chroots in /etc/sbuild/chroots instead. Does anyone have any comments about that? Since sudo access is required to chroot into them, is there any reason for them to be present in the user build directory, especially now that ~/build is entirely optional; it's now just $PWD. 2. Object orientation ---------------------- Other things recently done are the complete object-orientation of option parsing and configuration handling. Option parsing now directly wraps the configuration class, making it possible to drive the sbuild Sbuild::Build and Sbuild::Chroot classes independently of the command-line option parsing, making them embeddable in other code (I'm thinking of buildd here, which will no longer need to invoke sbuild; it just needs to instantiate and use the objects). buildd currently messes inside the chroot prior to invoking sbuild, which can break schroot if using it with session management (the chroot won't exist or be accessible until after sbuild sets up the session). This is now complete for sbuild and all sbuild-* helper programs. This still needs doing for wanna-build and buildd. Squeeze goals ============= 1. Refactoring of build code ---------------------------- Once these things are done, I'd like to tackle some larger problems for Squeeze by refactoring the Sbuild::Build class. This would include object orientation and cleanup of the dependency handling code, which would allow us to fix most of the bugs in the BTS related to bad handling of build-deps in corner cases, as well as allowing us to retain backward compatibility with buildd sbuild (alternative build-dep resolution algorithms are already selectable, though only used in a single simple case). 2. Database usage ----------------- I would also like to abstract out the handling of the build stats and wanna-build databases to allow use of backends other than BDB and MLDBM, since these are rather limited and slow. I'm thinking here of SQLite and Postgres as alternative backends, while still providing support for the old backends (if only a mechanism for dumping and upgrading to a newer backend). It might also be useful to collaborate with the UDD people if their database schema could accommodate what we need from it. The wanna-build and stats databases should probably also be integrated into the same database, since the stats can just be an extra table with relations to a package table Note: I did propose doing this a number of years back (2002), but this was rejected due to adding too many extra dependencies to sbuild/wanna-build/buildd, making bootstrapping new architectures too costly. These would be strictly optional, so bootstrapping would still be possible with a less functional build which just supported once backend (equivalent to the current state). 3. wanna-build and buildd ------------------------- wanna-build was refactored sufficiently to run for Lenny, but is still in poor shape. buildd and all its helper programs exist in the source tree, but are not yet tested and likely do not work as is. It would be great to get these refactored in the same manner as sbuild was refactored for Lenny (object-orientation, duplicated code elimination, use of strict Perl). This also includes documentation, given that most of the programs lack manual pages, and require a degree of arcane manual configuration which has been almost entirely eliminated (and completely documented) for sbuild. In keeping with (2) above, I'd like the wanna-build database usage completely abstracted out of all programs into a common module so that all programs can easily interact with the database through a common interface. As always, comments and suggestions are welcome, as are patches ;-) Regards, Roger -- .''`.
