doc build: speed up "make lint-docs"
Extend the trick we use to speed up the "clean" target to also extend to the "lint-docs" target. See 54df87555b1 (Documentation/Makefile: conditionally include doc.dep, 2020-12-08) for the "clean" implementation. The "doc-lint" target only depends on *.txt files, so we don't need to generate GIT-VERSION-FILE etc. if that's all we're doing. This makes the "make lint-docs" target more than 2x as fast: $ git show HEAD~:Documentation/Makefile >Makefile.old $ hyperfine -L f ",.old" 'make -f Makefile{f} lint-docs' Benchmark #1: make -f Makefile lint-docs Time (mean ± σ): 100.2 ms ± 1.3 ms [User: 93.7 ms, System: 6.7 ms] Range (min … max): 98.4 ms … 103.1 ms 29 runs Benchmark #2: make -f Makefile.old lint-docs Time (mean ± σ): 220.0 ms ± 20.0 ms [User: 206.0 ms, System: 18.0 ms] Range (min … max): 206.6 ms … 267.5 ms 11 runs Summary 'make -f Makefile lint-docs' ran 2.19 ± 0.20 times faster than 'make -f Makefile.old lint-docs' Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
