Rewrite of the "git bisect" script in C continues. * mr/bisect-in-c-2: bisect--helper: reimplement `bisect_next` and `bisect_auto_next` shell functions in C bisect: call 'clear_commit_marks_all()' in 'bisect_next_all()' bisect--helper: reimplement `bisect_autostart` shell function in C bisect--helper: introduce new `write_in_file()` function bisect--helper: use '-res' in 'cmd_bisect__helper' return bisect--helper: BUG() in cmd_*() on invalid subcommand

bisect--helper: reimplement `bisect_next` and `bisect_auto_next` shell functions in C

2020-09-24T19:06:30Z

Reimplement the `bisect_next()` and the `bisect_auto_next()` shell functions in C and add the subcommands to `git bisect--helper` to call them from git-bisect.sh . bisect_auto_next() function returns an enum bisect_error type as whole `git bisect` can exit with an error code when bisect_next() does. Return an error when `bisect_next()` fails, that fix a bug on shell script version. Using `--bisect-next` and `--bisect-auto-next` subcommands is a temporary measure to port shell function to C so as to use the existing test suite. As more functions are ported, `--bisect-auto-next` subcommand will be retired and will be called by some other methods.

bisect--helper: reimplement `bisect_autostart` shell function in C

2020-09-24T19:06:30Z

Reimplement the `bisect_autostart()` shell function in C and add the C implementation from `bisect_next()` which was previously left uncovered. Add `--bisect-autostart` subcommand to be called from git-bisect.sh. Using `--bisect-autostart` subcommand is a temporary measure to port the shell function to C so as to use the existing test suite. As more functions are ported, this subcommand will be retired and bisect_autostart() will be called directly by `bisect_state()`. Change behavior of shell script that returned success when user aborted the bisection.

bisect: swap command-line options in documentation

2020-08-28T21:06:06Z

The positional arguments are specified in this order: "bad" then "good". To avoid confusion, the options above the positional arguments are now specified in the same order. They can still be specified in any order since they're options, not positional arguments. Signed-off-by: Hugo Locurcio Signed-off-by: Junio C Hamano

bisect: add first-parent option to documentation

Ensure that the [--first-parent] option is listed in the output of "git bisect -h". Signed-off-by: Aaron Lipman Signed-off-by: Junio C Hamano

Merge branch 'al/bisect-first-parent'

2020-08-18T00:02:45Z

"git bisect" learns the "--first-parent" option to find the first breakage along the first-parent chain. * al/bisect-first-parent: bisect: combine args passed to find_bisection() bisect: introduce first-parent flag cmd_bisect__helper: defer parsing no-checkout flag rev-list: allow bisect and first-parent flags t6030: modernize "git bisect run" tests

cmd_bisect__helper: defer parsing no-checkout flag

2020-08-07T22:13:03Z

cmd_bisect__helper() is intended as a temporary shim layer serving as an interface for git-bisect.sh. This function and git-bisect.sh should eventually be replaced by a C implementation, cmd_bisect(), serving as an entrypoint for all "git bisect ..." shell commands: cmd_bisect() will only parse the first token following "git bisect", and dispatch the remaining args to the appropriate function ["bisect_start()", "bisect_next()", etc.]. Thus, cmd_bisect__helper() should not be responsible for parsing flags like --no-checkout. Instead, let the --no-checkout flag remain in the argv array, so it may be evaluated alongside the other options already parsed by bisect_start().
