There is a fairly simple technique to figure out the relationships based on using https://cgit.freebsd.org instead of a local .git copy. I'll give examples based on the notice's: releng/13.0/ ce9af53d0897a1cb926bd244f499fc09b1626b27 and examples of before (earlier date/time) and after (later date/time), presumably from some command like uname -apKU . The date/time-increasing order for the below is (for reference): 8305d6906fe983a . . . ce9af53d0897a1c . . . ba27dd8be821792 I'll follow the same steps with the before value vs. the after value substituted and report what results. I go to: https://cgit.freebsd.org/src/log/?h=releng/13.0 to match that part of the notice. (I'm not trying to specify which technique that one uses for this, just the result.) I select range and enter: 8305d6906fe983a~1..ce9af53d0897a1c (8305d6906fe983a happens to be a before ce9af53d0897a1c value): (Spacing in the ranges seems to be important to avoid.) The result is I see: Commit message (Expand) Author Age Files Lines (In other words an empty output/range meets the criteria for when uname -apKU reported an earlier date/time's commit.) By contrast . . . I again go to: https://cgit.freebsd.org/src/log/?h=releng/13.0 . I select range and enter: ba27dd8be821792~1..ce9af53d0897a1c (ba27dd8be821792 happens to be an after ce9af53d0897a1c value): Commit message (Expand) Author Age Files Lines * zfs: merge OpenZFS master-9312e0fd1 Martin Matuska 4 days 40 -248/+724 |\ | * Update vendor/openzfs to master-9312e0fd1vendor/openzfs Martin Matuska 4 days 36 -247/+716 * | Fix build after 2c7dc6bae9fd.

(goes on indefinately) . . . In other words it starts to list everything at ba27dd8be821792 or before (in time) for the branch. (Listing ba27dd8be821792 itself is why I use the ~1 part of the notation on the left hand hash-id.) (In other words a non-empty output/range meets the criteria for when uname -apKU reported a no-earlier date/time's commit, normally a later date/time's commit.) So the empty vs. non-empty result indicates the time relationship of the hash-ids on the branch. No need for a local .git of any kind but access to https://cgit.freebsd.org is needed for the technique. Notes: The order of the range specifications is deliberate in order to make the output harder to misinterpret. This is because . . .

(all the prior history) . . . and an empty vs. non-empty status is easier to tell apart. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
