Risect

example

Risect is a bisection tool, more friendly and general than git bisect.

vs git bisect

  • git bisect command set is hard to remember
  • git bisect takes efforts to eye-parse its stdout
  • git bisect cannot search commits of a dependency

Usage

You can use Risect in two ways.

  1. Pipe the search space to stdin
  2. Use the built-in setup (recommended)

For example, to simulate git bisect, you can directly use git rev-list or --git flag.

1. git rev-list master~5 .. master | risect -- sh -c "git checkout {} && ./test.sh"
2. risect --git master~5 master --  sh -c "git checkout {} && ./test.sh"

The second methods provide more meta data in addition to {} such as {author-name} or {author-email}. These can be used in test commands and report formats.

Configs (TODO)

  • --verbose
  • --parallel <n> runs (n+1)-ary search
  • --interactive

Built-in Types (TODO)

Git

risect --git --from HEAD~5 --to HEAD -- ./test.sh {}  # all commit hash list is determined before first run
risect --git --from HEAD~5 --to HEAD --path ./submodule -- ./test.sh {}  # git bisect on submodule
risect --git --from-date 2020-05-02 --to bbbb -- ./test.sh {}  # commits since --from-date
risect --git --from-date 2020-05-02 --n 5 -- ./test.sh {}  # 5 commits since --from-date

Dates

risect --date 2020-05-05 2020-05-20 -- ./test.sh {}

Numbers

seq 0 1.0 0.2 | risect -- ./test.sh --threshold={}

Custom

risect --custom "seq 0 1.0 0.2" -- ./test.sh --threshold={}
