Author: ngie Date: Mon Aug 14 19:03:05 2017 New Revision: 322511 URL: https://svnweb.freebsd.org/changeset/base/322511 Log: Add limited sandbox capability to "make check" == Rationale == r295380 introduced "make check" and consolidated means for running test code in an attempt to simplify running tests. One could either install files/libraries/programs and run "make check", or run "make check" with an explicit CHECKDIR, e.g., `make check CHECKDIR=$(make -V.OBJDIR)``. One criticism that was received is that "make check" should be run with the intent of making dev->test->commit easier, which means that the target audience's workflow should be developers. One developer pattern available in other opensource projects is to run test code from a developer sandbox, instead of installing to a system. == Method == This approach is slightly different from the standard approach, in the sense that it builds and installs into a deterministic directory under .OBJDIR (as I call it, the "sandbox"), then runs "make check" against that. In the event the test run is successful, the deterministic directory is removed to save space. == Approach == bsd.lib.mk, bsd.prog.mk: To support this functionality, a new variable `HAS_TESTS` is being added. HAS_TESTS enables appropriate behavior with bsd.lib.mk and bsd.prog.mk, as follows: - Add "make check" as an available target from the directory. - Pass down appropriate variables via ${TESTS_ENV}, i.e., ${TESTS_LD_LIBRARY_PATH} and ${TESTS_PATH}. One should add "HAS_TESTS" to directories containing tests in them, e.g. from bin/sh/Makefile, HAS_TESTS= SUBDIR.${MK_TESTS}+= tests HAS_TESTS doesn't automatically add the tests subdirectory for flexibility reasons. bsd.opts.mk, src.opts.mk: - The knob ${MK_MAKE_CHECK_USE_SANDBOX} has been added, both to explicitly direct (internally) when to set a deterministic ${DESTDIR} and to also allow users to disable this behavior globally, i.e., via src.conf. - MK_TESTS has been promoted from src.opts.mk to bsd.opts.mk to leverage syntactic sugar for having MK_TESTS be a dependency for MK_MAKE_CHECK_USE_SANDBOX, but to also ensure that src.opts.mk isn't required to use suite.test.mk (which is a dependency of bsd.test.mk). suite.test.mk: - beforecheck behavior (when MK_MAKE_CHECK_USE_SANDBOX is enabled) is modified from a no-op to: -- Build. -- Run "make hierarchy" on the sandbox dir. -- Install the tests/files to the sandbox dir. - aftercheck behavior (when MK_MAKE_CHECK_USE_SANDBOX is enabled) is modified from a no-op to: -- Remove the sandbox dir. Again, because the dependency order set in bsd.test.mk is beforecheck -> check -> aftercheck, "make check" will not be run unless "beforecheck" completes successfully, and "aftercheck" will not be run unless "beforecheck" and "check" complete successfully. == Caveats == - This target must either be run with MK_INSTALL_AS_USER or as root. Otherwise it will fail when running "make install" as the default user/group for many makefiles when calling INSTALL is root/wheel. - This target must be run from a suitable top-level directory. For example, running tests from `tests/sys/fs/tmpfs` won't work, but `tests/sys/fs` will, because `tests/sys/fs/tmpfs` relies on files installed by `tests/sys/fs`. - Running MK_INSTALL_AS_USER may introduce determinism issues. However, using it could identify deficiences in tests in terms of needing to be run as root, which are not properly articulated in the test requirements. - The doesn't negate the need for running "make installworld" and "make checkworld", etc. Again, this just is intended to simplify the dev->test->commit workflow. == Cleanup done == - CHECKDIR is removed; one can use "MK_MAKE_CHECK_USE_SANDBOX=no" to enable "legacy" (r295380) behavior. MFC after: 2 months Relnotes: yes (CHECKDIR removed; "make check" behavior changed) Requested by: jhb Reviewed by: arch (silence), testing (silence) Differential Revision: D11905 Added: head/tools/build/options/WITHOUT_MAKE_CHECK_USE_SANDBOX - copied, changed from r322452, head/tools/build/options/WITHOUT_TESTS Modified: head/share/mk/bsd.README head/share/mk/bsd.lib.mk head/share/mk/bsd.opts.mk head/share/mk/bsd.prog.mk head/share/mk/src.opts.mk head/share/mk/suite.test.mk Modified: head/share/mk/bsd.README ============================================================================== --- head/share/mk/bsd.README Mon Aug 14 18:49:46 2017 (r322510) +++ head/share/mk/bsd.README Mon Aug 14 19:03:05 2017 (r322511) @@ -566,7 +566,7 @@ It has seven targets: all: build the test programs. check: - runs the test programs from CHECKDIR with kyua test. + runs the test programs with kyua test.
