kbuild: deb-pkg: support DEB_BUILD_OPTIONS=parallel=N in debian/rules
'make srcdeb-pkg' generates a source package, which you can build
later by using dpkg-buildpackage.
In older dpkg versions, 'dpkg-buildpackage --jobs=N' sets not only
DEB_BUILD_OPTIONS but also MAKEFLAGS. Hence, passing -j or --jobs
to dpkg-buildpackage was enough for kicking the parallel execution.
The behavior was changed by commit 1d0ea9b2ba3f ("dpkg-buildpackage:
Change -j, --jobs semantics to non-force mode") of dpkg project. [1]
Since then, 'dpkg-buildpackage --jobs=N' sets only DEB_BUILD_OPTIONS,
which is not parsed by the current debian/rules. To build the package
in parallel, you need to pass the alternative --jobs-force option or
set the MAKEFLAGS environment variable.
Debian policy [2] suggests the following code snippet for debian/rules.
ifneq (,$(filter parallel=%,$(DEB_BUILD_OPTIONS)))
NUMJOBS = $(patsubst parallel=%,%,$(filter parallel=%,$(DEB_BUILD_OPTIONS)))
MAKEFLAGS += -j$(NUMJOBS)
endif
I tweaked the code to filter out parallel=1 and passed --jobs=1 to
dpkg-buildpackage from scripts/Makefile.package. It is needed to force
'make deb-pkg' without the -j option to run in serial. Please note that
dpkg-buildpackage sets parallel=<nproc> in DEB_BUILD_OPTIONS by default
(that is, --jobs=auto is the default) and --jobs=1 is needed to restore
the serial execution. When dpkg-buildpackage is invoked from Kbuild,
the number of jobs is inherited from the top level Makefile. Passing
--jobs=1 to dpkg-buildpackage allows debian/rules to skip parsing
DEB_BUILD_OPTIONS.

kbuild: deb-pkg: set DEB_* variables if debian/rules is directly executed
Since commit 491b146d4c13 ("kbuild: builddeb: Eliminate debian/arch
use"), direct execution of debian/rules results in the following error:
dpkg-architecture: error: unknown option 'DEB_HOST_MULTIARCH'
The current code:
dpkg-architecture -a$DEB_HOST_ARCH -qDEB_HOST_MULTIARCH
... does not look sensible because:
- For this code to work correctly, DEB_HOST_ARCH must be pre-defined,
which is true when the packages are built via dpkg-buildpackage.
In this case, DEB_HOST_MULTIARCH is also likely defined, hence there
is no need to query DEB_HOST_MULTIARCH in the first place.
- If DEB_HOST_MULTIARCH is undefined, DEB_HOST_ARCH is likely undefined
too. So, you cannot query DEB_HOST_MULTIARCH in this way. This is
mostly the case where debian/rules is directly executed.
When debian/rules is directly executed, querying DEB_HOST_MUCHARCH is
not enough because we need to know DEB_{BUILD,HOST}_GNU_TYPE as well.
All DEB_* variables are defined when the package build is initiated by
dpkg-buildpackage, but otherwise, let's call dpkg-architecture to set
all DEB_* environment variables.
This requires dpkg 1.20.6 or newer because --print-format option
was added in dpkg commit 7c54fa2b232e ("dpkg-architecture: Add a
--print-format option").
