In the previous patch series (v3), I implemented the equivalent to the cat command but I understood reviewers wanted to print the output to the user, so I reverted my changes for this version. https://lore.kernel.org/git/20210411095538.34129-4-mirucam@gmail.com/ > > > + > > + if (res == BISECT_ONLY_SKIPPED_LEFT) > > + error(_("bisect run cannot continue any more")); > > + else if (res == BISECT_INTERNAL_SUCCESS_MERGE_BASE) { > > + printf(_("bisect run success")); > > + res = BISECT_OK; > > + } else if (res == BISECT_INTERNAL_SUCCESS_1ST_BAD_FOUND) { > > + printf(_("bisect found first bad commit")); > > + res = BISECT_OK; > > + } else if (res) { > > + error(_("bisect run failed:'git bisect--helper --bisect-state" > > + " %s' exited with error code %d"), args.v[0], res); > > + } else { > > + exit = 0; > > Since the only purpose of `exit` seems to be that the loop should continue > if `exit` is set to 0, and it is only set here, how about doing away with > the variable altogether and writing `continue;` instead of `exit = 0;`? > Then the conditional block below does not need to be conditional. > Noted. > Other than that: well done! > Thank you for reviewing!, Miriam > Ciao, > Dscho > > > + } > > + > > + if (exit) { > > + strbuf_release(&command); > > + strvec_clear(&args); > > + strvec_clear(&run_args); > > + return res; > > + } > > + } > > +} > > + > > int cmd_bisect__helper(int argc, const char **argv, const char *prefix) > > { > > enum { > > @@ -1089,6 +1155,7 @@ int cmd_bisect__helper(int argc, const char **argv, const char *prefix) > > BISECT_REPLAY, > > BISECT_SKIP, > > BISECT_VISUALIZE, > > + BISECT_RUN, > > } cmdmode = 0; > > int res = 0, nolog = 0; > > struct option options[] = { > > @@ -1112,6 +1179,8 @@ int cmd_bisect__helper(int argc, const char **argv, const char *prefix) > > N_("skip some commits for checkout"), BISECT_SKIP), > > OPT_CMDMODE(0, "bisect-visualize", &cmdmode, > > N_("visualize the bisection"), BISECT_VISUALIZE), > > + OPT_CMDMODE(0, "bisect-run", &cmdmode, > > + N_("use <cmd>... to automatically bisect."), BISECT_RUN), > > OPT_BOOL(0, "no-log", &nolog, > > N_("no log for BISECT_WRITE")), > > OPT_END() > > @@ -1177,6 +1246,12 @@ int cmd_bisect__helper(int argc, const char **argv, const char *prefix) > > get_terms(&terms); > > res = bisect_visualize(&terms, argv, argc); > > break; > > + case BISECT_RUN: > > + if (!argc) > > + return error(_("bisect run failed: no command provided.")); > > + get_terms(&terms); > > + res = bisect_run(&terms, argv, argc); > > + break; > > default: > > BUG("unknown subcommand %d", cmdmode); > > } > > diff --git a/git-bisect.sh b/git-bisect.sh > > index 95f7f3fb8c..e83d011e17 100755 > > --- a/git-bisect.sh > > +++ b/git-bisect.sh > > @@ -39,66 +39,6 @@ _x40="$_x40$_x40$_x40$_x40$_x40$_x40$_x40$_x40" > > TERM_BAD=bad > > TERM_GOOD=good > > > > -bisect_run () { > > - git bisect--helper --bisect-next-check $TERM_GOOD $TERM_BAD fail || exit > > - > > - test -n "$*" || die "$(gettext "bisect run failed: no command provided.")" > > - > > - while true > > - do > > - command="$@" > > - eval_gettextln "running \$command" > > - "$@" > > - res=$? > > - > > - # Check for really bad run error. > > - if [ $res -lt 0 -o $res -ge 128 ] > > - then > > - eval_gettextln "bisect run failed: > > -exit code \$res from '\$command' is < 0 or >= 128" >&2 > > - exit $res > > - fi > > - > > - # Find current state depending on run success or failure. > > - # A special exit code of 125 means cannot test. > > - if [ $res -eq 125 ] > > - then > > - state='skip' > > - elif [ $res -gt 0 ] > > - then > > - state="$TERM_BAD" > > - else > > - state="$TERM_GOOD" > > - fi > > - > > - git bisect--helper --bisect-state $state >"$GIT_DIR/BISECT_RUN" > > - res=$? > > - > > - cat "$GIT_DIR/BISECT_RUN" > > - > > - if sane_grep "first $TERM_BAD commit could be any of" "$GIT_DIR/BISECT_RUN" \ > > - >/dev/null > > - then > > - gettextln "bisect run cannot continue any more" >&2 > > - exit $res > > - fi > > - > > - if [ $res -ne 0 ] > > - then > > - eval_gettextln "bisect run failed: > > -'bisect-state \$state' exited with error code \$res" >&2 > > - exit $res > > - fi > > - > > - if sane_grep "is the first $TERM_BAD commit" "$GIT_DIR/BISECT_RUN" >/dev/null > > - then > > - gettextln "bisect run success" > > - exit 0; > > - fi > > - > > - done > > -} > > - > > get_terms () { > > if test -s "$GIT_DIR/BISECT_TERMS" > > then > > @@ -137,7 +77,7 @@ case "$#" in > > log) > > git bisect--helper --bisect-log || exit ;; > > run) > > - bisect_run "$@" ;; > > + git bisect--helper --bisect-run "$@" || exit;; > > terms) > > git bisect--helper --bisect-terms "$@" || exit;; > > *) > > -- > > 2.29.2 > > > >

If so, I think we do need to show the contents by opening the file and piping it to `stdout`. FWIW I read https://lore.kernel.org/git/CAP8UFD3X24F3qgefHpi00PM-KUk+vcqxwy2Dbngbyj7ciavCVQ@mail.gmail.com/ to mean the same thing, although I have to admit that I am not 100% certain. Just to make sure: with this patch, at the end of a `git bisect` run, the user is shown the commit message of the first bad commit? Ciao, Dscho

I agree that, after `bisect_state()` has written into the `BISECT_RUN` file, we should indeed be opening it and piping it to `stdout`. That's what I meant in the above message.

Thank you for the clarification! Best, Miriam.
