Hello, Git Version 2.24.0.windows.2 Summary: triple dots git diff L...R -- foo <=> diff between CommonAncestror(L,R) to R git log L...R <=> all commit from L to R double dots git diff L..R -- foo <=> diff between L and R git log L..R <=> commit from CommonAncestror(L,R) to R So, to make the command related to the common ancestor, git diff uses the triple dots notation by opposite to git log that uses the double dots notation In details ------------ ####################################################### The ... (triple dots notation) In the diff context, the triple dots notation is related to the common ancestror: git diff L...R -- foo means diff between (common ancestor of L and R) and R is equivalent to: git diff $(git merge-base L R) R -- foo But now, if I use the same notation for git log, it means all the commit that differ from L to R Example, you can execute the following lines: mkdir test cd test git init echo common > foo git add foo git ci -m "add common part" git switch -c L echo LeftPart >> foo git ci -am "add a left part" git switch master git switch -c R echo "right part" >> foo git ci -am "add a right part" git switch master git diff L...R -- foo And verify: $ git diff L...R -- foo diff --git a/foo b/foo index 30e1159..2570fa8 100644 --- a/foo +++ b/foo @@ -1 +1,2 @@ common +right part As expected, only the right part appears. and now with the log: $ git log --oneline --left-right L...R > f2f11c4 (tag: R) R: add a right part < 7f4f3d6 (tag: L) L: add a left part The log that concers the left part appears too! ################################################################## If now we consider the .. (double dots notation), it is exactly the opposite! $ git diff L..R -- foo diff --git a/foo b/foo index 6f2cf25..2570fa8 100644 --- a/foo +++ b/foo @@ -1,2 +1,2 @@ common -LeftPart +right part It is clear that both branches differences appear and with git log: $ git log --oneline --left-right L..R > f2f11c4 (tag: R) R: add a right part For the log, only the commit from the common ancestror to R appear ! So there is well an incoherence between diff and log using the multi-dots notation Best regards, Arnaud Bertrand
