Currently, bulk build results are sent to the pkgsrc-bulk mailing list. To figure out if a package is or has been building successfully, or when it broke, one must wade through the list archives and search the report e-mails by hand. Furthermore, to figure out what commits if any were correlated with a breakage, one must wade through the pkgsrc-changes archive and cross-reference manually.

The project is to produce a web/database application that can be run from the pkgsrc releng website on NetBSD.org that tracks bulk build successes and failures and provides search and crossreferencing facilities.

The application should subscribe to the pkgsrc-bulk and pkgsrc-changes mailing lists and ingest the data it finds into a SQL database. It should track commits to each package (and possibly infrastructure changes that might affect all packages) on both HEAD and the current stable branch, and also all successful and failed build reports on a per-platform (OS and/or machine type) basis.

The web part of the application should be able to retrieve summaries of currently broken packages, in general or for a specific platform and/or specific branch. It should also be able to generate a more detailed report about a single package, containing for example which platforms it has been built on recently and whether it succeeded or not; also, if it is broken, how long it has been broken, and the history of package commits and version bumps vs. build results. There will likely be other searches/reports wanted as well.

The application should also have an interface for people who do partial or individual-package check builds; that is, it should be able to generate a list of packages that have not been built since they were last committed, on a given platform or possibly on a per-user basis, and accept results from attempting to build these or subsets of these packages. It is not entirely clear what this interface should be (and e.g. whether it should be command-line-based, web-based, or what, and whether it should be limited to developers) and it's reasonable to expect that some refinements or rearrangements to it will be needed after the initial deployment.

The application should also be able to record cross-references to the bug database. To begin with at least it's reasonable for this to be handled manually.

This project should be a routine web/database application; there is nothing particularly unusual about it from that standpoint. The part that becomes somewhat less trivial is making all the data flows work: for example, it is probably necessary to coordinate an improvement in the way bulk build results are tagged by platform. It is also necessary to avoid importing the reports that appear occasionally on pkgsrc-bulk from misconfigured pbulk installs.

Note also that "OS" and "machine type" are not the only variables that can affect build outcome. There are also multiple compilers on some platforms, for which the results should be tracked separately, plus other factors such as non-default installation paths. Part of the planning phase for this project should be to identify all the variables of this type that should be tracked.

Also remember that what constitutes a "package" is somewhat slippery as well. The pkgsrc directory for a package is not a unique key; multiversion packages, such as Python and Ruby extensions, generate multiple results from a single package directory. There are also a few packages where for whatever reason the package name does not match the pkgsrc directory. The best key seems to be the pkgsrc directory paired with the package-name-without-version.
