Summary: make 4.4: different behavior with -j1 and -j2 when building manpages from git Project: make Submitter: kanavin Submitted: Mon 14 Nov 2022 10:04:36 AM UTC Severity: 3 - Normal Item Group: Bug Status: None Privacy: Public Assigned to: None Open/Closed: Open Discussion Lock: Any Component Version: 4.4 Operating System: POSIX-Based Fixed Release: None Triage Status: None _______________________________________________________ Follow-up Comments: ------------------------------------------------------- Date: Mon 14 Nov 2022 10:04:36 AM UTC By: Alexander Kanavin <kanavin> When building git v2.38.1 (https://github.com/git/git/tags) I noticed that make 4.4 behaves differently depending on parallelism settings. alex@alex-lx-laptop:~/development/git/Documentation$ ../../make-4.4/make -j1 git-add.1 SUBDIR ../ make[1]: 'GIT-VERSION-FILE' is up to date. vs alex@alex-lx-laptop:~/development/git/Documentation$ ../../make-4.4/make -j2 git-add.1 SUBDIR ../ make[1]: 'GIT-VERSION-FILE' is up to date. XMLTO git-add.1 Makefile:355: warning: pattern recipe did not update peer target 'git-add.7'. Makefile:355: warning: pattern recipe did not update peer target 'git-add.5'. Manpages are rebuilt without need, if j is more than one. I believe this is triggered by FORCE flag for one of the rules in the makefile, but still the difference in behavior depending on what is in -j does not seem correct. https://github.com/git/git/blob/v2.38.1/Documentation/Makefile#L326 I also confirmed that with make 4.3 this does not happen: manpages are not rebuilt, regardless of -j. FORCE does not have an effect on this. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?63362> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
