Future Tasks
============

Functional Changes
------------------

  * Support a field for annotating transitional packages, to help notify
    maintainers when their source packages depend on development packages for
    old library SONAME versions.
    - Add optional `Deprecated: yes[ <replacement-pkg>]` binary package field to
      SPF 2.0.  Note that this does not replace package relationship fields like
      `Depends`.
    - (Debian uses `Section: oldlibs` for this, but ProteanOS uses `Section` to
      separate packages into smaller indices that not all systems use, so we
      shouldn't just dump all transitional packages into one big section.  Also,
      ProteanOS uses `Section` to determine whether to architecture-qualify
      names of multiarch coinstallable packages.)
    - Add `Deprecated` to `lib/package/2.sh` `_OB_BINARY_FIELDS_OPTIONAL_2`.
    - Add an option to opkbuild to disable build dependency deprecation
      failures.  Maybe replace `-D`.  Set an environment variable for
      ob-checkbuilddeps.
    - Run `opkg info` instead of `opkg status` in ob-checkbuilddeps
      `check_dep()`.  If a `Deprecated` field exists, call `ob_error()` with the
      name of the replacement package (if any).  If build dependency deprecation
      failures are enabled, exit with an error status.
    - Make opkbuild always run ob-checkbuilddeps regardless of `-d` option and
      only exit with an error status if ob-checkbuilddeps fails and `-d` is
      specified.
  * Make binary package `Description` fields architecture- and platform-
    independent (so a packages index Web site can show one description for a
    binary package for all its architectures and platforms).
    - Specify in SPF 2.0 #substvars-defined that `Host-Arch` and `Host-Plat`
      substitution variables shall not be set for `Description` fields.
    - `ob_set_source_substvar()` needs a third optional (for API compatibility)
      `archplat_dep` parameter (default `false`) that, if `true`, causes
      variable to be stored in a separate array.
    - `ob_set_package_substvars()` needs a second optional (for API
      compatibility) `archplat_indep` parameter (default `false`) that, if
      `false`, enables checking for variables in the aforementioned separate
      array.
    - In `_ob_set_package_substvars_2()`, replace:
          ob_set_source_substvar 'Host-Arch' "${OPK_HOST_ARCH}"
          ob_set_source_substvar 'Host-Plat' "${OPK_HOST_PLAT}"
      with:
          ob_set_source_substvar 'Host-Arch' "${OPK_HOST_ARCH}" true
          ob_set_source_substvar 'Host-Plat' "${OPK_HOST_PLAT}" true
    - In ob-gencontrol, replace:
          desc="$(ob_substvars "${desc}" "${pkg}")"
      with:
          desc="$(ob_substvars "${desc}" "${pkg}" true)"
    - Add `${Host-Arch}` (which should be copied verbatim to output control
      file) to `Description` in tests **BEFORE** above changes to verify correct
      behavior.
  * Split distribution packaging from upstream sources in source packages.
    - Non-native package:
      * `src:foo` is the distribution packaging, and it depends on
        `src:foo:upstream`
      * If the revision isn't "1", don't build and upload upstream sources.
      * pro-archman will need some modifications to handle this.
    - Native package:
      * `src:foo` is the whole package.
      * Upload everything always.
  * ob-installdocs: Handle non-directory non-regular files?
  * Someday restore (removed in commit 3cc4e19) and implement
    `ob_summarize_package_arch()` and `ob_summarize_package_plat()` to queue
    source packages for build daemons.
