  "message": "replay: add --revert mode to reverse commit changes\n\nAdd a `--revert \u003cbranch\u003e` mode to git replay that undoes the changes\nintroduced by the specified commits. Like --onto and --advance, --revert\nis a standalone mode: it takes a branch argument and updates that branch\nwith the newly created revert commits.\n\nAt GitLab, we need this in Gitaly for reverting commits directly on bare\nrepositories without requiring a working tree checkout.\n\nThe approach is the same as sequencer.c\u0027s do_pick_commit() -- cherry-pick\nand revert are just the same three-way merge with swapped arguments:\n\n  - Cherry-pick: merge(ancestor\u003dparent, ours\u003dcurrent, theirs\u003dcommit)\n  - Revert: merge(ancestor\u003dcommit, ours\u003dcurrent, theirs\u003dparent)\n\nWe swap the base and pickme trees passed to merge_incore_nonrecursive()\nto reverse the diff direction.\n\nReverts are processed newest-first (matching git revert behavior) to\nreduce conflicts by peeling off changes from the top. Each revert\nbuilds on the result of the previous one via the last_commit fallback\nin the main replay loop, rather than relying on the parent-mapping\nused for cherry-pick.\n\nRevert commit messages follow the usual git revert conventions: prefixed\nwith \"Revert\" (or \"Reapply\" when reverting a revert), and including\n\"This reverts commit \u003chash\u003e.\". The author is set to the current user\nrather than preserving the original author, matching git revert behavior.\n\nHelped-by: Christian Couder \u003cchristian.couder@gmail.com\u003e\nHelped-by: Patrick Steinhardt \u003cps@pks.im\u003e\nHelped-by: Elijah Newren \u003cnewren@gmail.com\u003e\nHelped-by: Phillip Wood \u003cphillip.wood123@gmail.com\u003e\nHelped-by: Johannes Schindelin \u003cJohannes.Schindelin@gmx.de\u003e\nHelped-by: Junio C Hamano \u003cgitster@pobox.com\u003e\nHelped-by: Toon Claes \u003ctoon@iotcl.com\u003e\nSigned-off-by: Siddharth Asthana \u003csiddharthasthana31@gmail.com\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
