Subject: dpkg: please accept ":native" multiarch qualifier in build dependencies

Date: Thu, 26 Nov 2009 12:20:59 +0100

Package: dpkg
Version: 1.15.5.2
Severity: wishlist
User: debian-embedded@lists.debian.org
Usertags: multiarch-cross

Hi,

We would like to allow people to prepare their packages for
cross-compiling. Most functionality is already in place, however we are
still lacking a way to distinguish between build dependencies that are
required as tools (e.g. debhelper) or for building a tool (e.g. zlib-dev
for building a jar archiver which is then used to build a JAR file), and
build dependencies required for linking (e.g. zlib-dev for building a
java interpreter which can then unpack the JAR file).

The multiarch specification solves this to some extent, as tools are
marked "Multi-Arch: foreign" and libraries "Multi-Arch: same", which
allows us to have reasonable defaults by requiring "foreign" packages to
be installed in working order (i.e. preferentially DEB_BUILD_ARCH, but
any working one will do) and "same" packages in the version required for
linking (i.e. DEB_HOST_ARCH).

The cases not handled by the multi-arch specification are:

 - A library package (M-A: same) is to be installed for DEB_BUILD_ARCH.
 - A hybrid package (M-A: allowed) is to be installed for
   DEB_BUILD_ARCH.
 - A hybrid package (M-A: allowed) is to be installed for any
   architecture.

The last case is somewhat implied in the original specification (":any"
qualifier in Depends lines), but never explicitly allowed for
Build-Depends; the others require introducing a new qualifier that is
only meaningful in build dependencies.

In phase one, which needs to happen before the squeeze release for this
to be useful, it would therefore be good if ":any" and ":native"
qualifiers in build dependencies were accepted. As Debian itself does
not yet cross-compile packages, actually supporting the specified
resolution is optional (but would be nice to have in
dpkg-checkbuilddeps).

A minimal implementation would accept those qualifiers in all tools that
handle Build-Depends fields, but interpret the field as if the
qualifiers were not present (thus falling back to the strictest possible
interpretation for a native build).

A full implementation would resolve the dependencies according to the
table on the specification page[1].

[Message part 1 (text/plain, inline)]

Package: dpkg-dev
Version: 1.16.2
Followup-For: Bug #558095

Here is a patch implementing “:any” and “:native” qualifiers as
specified in the Multiarch spec and MultiarchCross.

This introduces a difference between regular Deps and Build-Deps: the second
now allows the “:native”, disallowed in the former.
This is implemented by adding a new “build_dep” option to deps_parse.
When this option is disabled (which it is by default), the “:native”
qualifier is rejected with a parse error. Otherwise, it is accepted and handled
according to the MultiarchCross spec.

This change might need changes in other packages as well, namely, src:sbuild
and src:emdebian-crush. I will take care of that if this patch is approved.

Another point not mentionned in the current version of MultiarchCross is the
implicit dependency on “build-essential”.
As it doesn't make sense to depend on “build-essential” for a foreign arch,
I've changed this build-dependency to “build-essential:native”.
An implicit build-dep on “build-essential-cross-$DEB_HOST_ARCH” or
something similar would probably make sense, but such a package doesn't exist
yet, nor has it been described in the current specification.

Last but not least, dpkg-buildpackage's “-a” option doesn't imply “-d”
anymore, as it is now able to resolve the dependencies correctly (provided that
the source package gets updated). Of course, the “-d” switch can still be
used.

   [ Raphaël Hertzog ]
   * dpkg-source will now clean up after a failed application of a quilt
     patch. Closes: #652970
     And it will display a message explaining the most likely cause of
     failure (patch applying with fuzz).
   * When dpkg-source regenerates the automatic patch (with formats "2.0"
     or "3.0 (quilt)") it will keep the current patch header to avoid
     losing changes made by the maintainer.
   * Modify dpkg-source --commit to auto-whitelist modified binary files.
     That way the same command can be used whatever kind of upstream files
     has been modified.
   * dpkg-source now supports a new option --no-unapply-patches to force
     patches to be kept applied after build (used by formats "2.0" and "3.0
     (quilt)"). Closes: #643043

   * Add support for “binary-only” key-value option in changelogs, to allow
     marking changelog entries as part of a binary only upload, having a
     different version from the source package. Closes: #440094, #672723
   * Minimize source architecture list on «dpkg-source -b» by removing
     architectures already covered by architecture wildcards. Closes: #675333
   * Do not assume $ENV{'HOME'} is defined in Dpkg::Source::Package.
     Thanks to Niels Thykier <niels@thykier.net>. Closes: #677631
   * Document in more detail in deb(5) the supported ar archive format.
   * Document in deb-src-control(5) the “Private-” field prefix.

     descriptors on --background. Closes: #627333, #64642
   * Switch source compression to xz.
   * Detect ar header fields truncation due to too long member names or too
     large member sizes. Closes: #678933
   * Add new dpkg-query --control-list and --control-show commands, which
     replace the now deprecated --control-path.
   * Print master and slave alternarive link names in update-alternatives
     --query and always print alternative link in --config. Closes: #679010
   * Cleanup and clarify buffer I/O error reporting. Closes: #621763
