   16: Currently, bulk build results are sent to the pkgsrc-bulk mailing
   17: list. To figure out if a package is or has been building successfully,
   18: or when it broke, one must wade through the list archives and search
   19: the report e-mails by hand. Furthermore, to figure out what commits if
   20: any were correlated with a breakage, one must wade through the
   21: pkgsrc-changes archive and cross-reference manually.
   23: The project is to produce a web/database application that can be run
   24: from the pkgsrc releng website on that tracks bulk build
   25: successes and failures and provides search and crossreferencing
   26: facilities.
   28: The application should subscribe to the pkgsrc-bulk and pkgsrc-changes
   29: mailing lists and ingest the data it finds into a SQL database. It
   30: should track commits to each package (and possibly infrastructure
   31: changes that might affect all packages) on both HEAD and the current
   32: stable branch, and also all successful and failed build reports on a
   33: per-platform (OS and/or machine type) basis.
   35: The web part of the application should be able to retrieve summaries
   36: of currently broken packages, in general or for a specific platform
   37: and/or specific branch. It should also be able to generate a more
   38: detailed report about a single package, containing for example which
   39: platforms it has been built on recently and whether it succeeded or
   40: not; also, if it is broken, how long it has been broken, and the
   41: history of package commits and version bumps vs. build results. There
   42: will likely be other searches/reports wanted as well.
   44: The application should also have an interface for people who do
   45: partial or individual-package check builds; that is, it should be able
   46: to generate a list of packages that have not been built since they
   47: were last committed, on a given platform or possibly on a per-user
   48: basis, and accept results from attempting to build these or subsets of
   49: these packages. It is not entirely clear what this interface should be
   50: (and e.g. whether it should be command-line-based, web-based, or what,
   51: and whether it should be limited to developers) and it's reasonable to
   52: expect that some refinements or rearrangements to it will be needed
   53: after the initial deployment.
   55: The application should also be able to record cross-references to the
   56: bug database. To begin with at least it's reasonable for this to be
   57: handled manually.
   59: This project should be a routine web/database application; there is
   60: nothing particularly unusual about it from that standpoint. The part
   61: that becomes somewhat less trivial is making all the data flows work:
   62: for example, it is probably necessary to coordinate an improvement in
   63: the way bulk build results are tagged by platform. It is also
   64: necessary to avoid importing the reports that appear occasionally on
   65: pkgsrc-bulk from misconfigured pbulk installs.
   67: Note also that "OS" and "machine type" are not the only variables that
   68: can affect build outcome. There are also multiple compilers on some
   69: platforms, for which the results should be tracked separately, plus
   70: other factors such as non-default installation paths. Part of the
   71: planning phase for this project should be to identify all the
   72: variables of this type that should be tracked.
   74: Also remember that what constitutes a "package" is somewhat slippery
   75: as well. The pkgsrc directory for a package is not a unique key;
   76: multiversion packages, such as Python and Ruby extensions, generate
   77: multiple results from a single package directory. There are also a few
   78: packages where for whatever reason the package name does not match the
   79: pkgsrc directory. The best key seems to be the pkgsrc directory paired
   80: with the package-name-without-version.
