Package: debhelper
Version: 7.9.3
Severity: wishlist
Tags: patch
Hello,
CTest (CMake test suite runner) as of 2.8 supports running tests in parallel
(-jN) option. This patch adds support for this feature to the debhelper cmake
build system (see commit message).
Fortunately, ctest does not seem to choke on unknown options so this change
should not break CTest 2.6 or earlier. Another issue is "unlimited paralel".
Unlike makefile, CTest parallel is typically not dependency based so running
with huge number of threads (-j999) is likely to run all existing tests in
paralel and if there is a huge number of them, this will kill every machine
which is not a supercomputer. So whoever uses `dpkg-buildpackage -j` (without
parallel limit) may burn. Therefore, feel free to reduce that value if you
wish. IMHO, people using `dpkg-buildpackage -j` (very unwise choice) get what
they asked for and deserve this "lesson".

Subject: [PATCH] Add support for running tests in parallel to the cmake build
system.
Pass appropriate -jN option to ctest (via ARGS variable in the Makefile) to
enable support for running tests in parallel. Similarly to makefile build
system, ctest -j1 mode is enforced even when parallel mode in debhelper is not
explicitly enabled.
Unlike make, CTest does not have "unlimited parallel" setting (-j implies -j1).
So in order to simulate unlimited parallel, allow to fork a huge number of
threads instead.

Description:
debhelper - helper programs for debian/rules
Closes: 587885 601590
Changes:
debhelper (8.9.4) unstable; urgency=low
.
* dh: The --before --after --until and --remaining options are deprecated.
Use override targets instead.
* Assume that the package can be cleaned (i.e. the build directory can be
removed) as long as it is built out-of-source tree and can be configured.
This is useful for derivative buildsystems which generate Makefiles.
(Modestas Vainius) Closes: #601590
* dh_auto_test: Run cmake tests in parallel when allowed by
DEB_BUILD_OPTIONS. (Modestas Vainius) Closes: #587885
* dpkg-buildflags is only used to set environment in v9, to avoid
re-breaking packages that were already broken a first time by
dpkg-buildpackage unconditionally setting the environment, and
worked around that by unsetting variables in the rules file.
