It tries to carefully detect criss-cross + merge ambiguities and is considered generally safe and + fast. + +recursive:: + This can only resolve two heads using 3-way merge + algorithm. When there are more than one common + ancestors that can be used for 3-way merge, it creates a + merged tree of the common ancestors and uses that as + the reference tree for the 3-way merge. This has been + reported to result in fewer merge conflicts without + causing mis-merges by tests done on actual merge commits + taken from Linux 2.6 kernel development history. + Additionally this can detect and handle merges involving + renames. This is the default merge strategy when + pulling or merging one branch. + +octopus:: + This resolves more than two-head case, but refuses to do + complex merge that needs manual resolution. It is + primarily meant to be used for bundling topic branch + heads together. This is the default merge strategy when + pulling or merging more than one branches. + +ours:: + This resolves any number of heads, but the result of the + merge is always the current branch head. It is meant to + be used to supersede old development history of side + branches. + +subtree:: + This is a modified recursive strategy. When merging trees A and + B, if B corresponds to a subtree of A, B is first adjusted to + match the tree structure of A, instead of reading the trees at + the same level. This adjustment is also done to the common + ancestor tree. |
