Both are opt-in: an unset glob is no opinion, not refuse-everything, so a repository that never set one commits exactly as before. Set binary-glob to *.png and PNGs are the binaries the project expects, so a stray .o is refused. Neither runs code, so unlike before-commit they bind a fresh clone with no consent step -- that asymmetry is why they exist.

The check gates what a commit INTRODUCES: an all-files commit re-captures every managed path, so classifying unchanged content would make declaring a glob block every later commit until the whole tree already conformed. Comparing against the parent's blob grandfathers inherited files, per content rather than per path, so editing one re-checks it.

--no-checks waives it, the same flag that waives before-commit. check-in: 2711adbb03 user: dmestas tags: trunk
