|
879 | 879 | |
|
880 | 880 | Rebase uses repeated merging to graft changesets from one part of |
|
881 | 881 | history (the source) onto another (the destination). This can be |
|
882 | 882 | useful for linearizing *local* changes relative to a master |
|
883 | 883 | development tree. |
|
884 | 884 | |
|
885 | 885 | Published commits cannot be rebased (see :hg:`help phases`). |
|
886 | 886 | To copy commits, see :hg:`help graft`. |
|
887 | 887 | |
|
888 | 888 | If you don't specify a destination changeset (``-d/--dest``), rebase |
|
889 | 889 | will use the same logic as :hg:`merge` to pick a destination. if |
|
890 | 890 | the current branch contains exactly one other head, the other head |
|
891 | 891 | is merged with by default. Otherwise, an explicit revision with |
|
892 | 892 | which to merge with must be provided. (destination changeset is not |
|
893 | 893 | modified by rebasing, but new changesets are added as its |
|
894 | 894 | descendants.) |
|
895 | 895 | |
|
896 | 896 | Here are the ways to select changesets: |
|
897 | 897 | |
|
898 | 898 | 1. Explicitly select them using ``--rev``. |
|
899 | 899 | |
|
900 | 900 | 2. Use ``--source`` to select a root changeset and include all of its |
|
901 | 901 | descendants. |
|
902 | 902 | |
|
903 | 903 | 3. Use ``--base`` to select a changeset; rebase will find ancestors |
|
904 | 904 | and their descendants which are not also ancestors of the destination. |
|
905 | 905 | |
|
906 | 906 | 4. If you do not specify any of ``--rev``, ``--source``, or ``--base``, |
|
907 | 907 | rebase will use ``--base .`` as above. |
|
908 | 908 | |
|
909 | 909 | If ``--source`` or ``--rev`` is used, special names ``SRC`` and ``ALLSRC`` |
|
910 | 910 | can be used in ``--dest``. Destination would be calculated per source |
|
911 | 911 | revision with ``SRC`` substituted by that single source revision and |
|
912 | 912 | ``ALLSRC`` substituted by all source revisions. |
|
913 | 913 | |
|
914 | 914 | Rebase will destroy original changesets unless you use ``--keep``. |
|
915 | 915 | It will also move your bookmarks (even if you do). |
|
916 | 916 | |
|
917 | 917 | Some changesets may be dropped if they do not contribute changes |
|
918 | 918 | (e.g. merges from the destination branch). |
|
919 | 919 | |
|
920 | 920 | Unlike ``merge``, rebase will do nothing if you are at the branch tip of |
|
921 | 921 | a named branch with two heads. You will need to explicitly specify source |
|
922 | 922 | and/or destination. |
|
923 | 923 | |
|
924 | 924 | If you need to use a tool to automate merge/conflict decisions, you |
|
925 | 925 | can specify one with ``--tool``, see :hg:`help merge-tools`. |
|
926 | 926 | As a caveat: the tool will not be used to mediate when a file was |
|
927 | 927 | deleted, there is no hook presently available for this. |
|
928 | 928 | |
|
929 | 929 | If a rebase is interrupted to manually resolve a conflict, it can be |
|
930 | 930 | continued with --continue/-c, aborted with --abort/-a, or stopped with |
|
931 | 931 | --stop. |

|
934 | 934 | |
|
935 | 935 | Examples: |
|
936 | 936 | |
|
937 | 937 | - move "local changes" (current commit back to branching point) |
|
938 | 938 | to the current branch tip after a pull:: |
|
939 | 939 | |
|
940 | 940 | hg rebase |
|
941 | 941 | |
|
942 | 942 | - move a single changeset to the stable branch:: |
|
943 | 943 | |
|
944 | 944 | hg rebase -r 5f493448 -d stable |
|
945 | 945 | |
|
946 | 946 | - splice a commit and all its descendants onto another part of history:: |
|
947 | 947 | |
|
948 | 948 | hg rebase --source c0c3 --dest 4cf9 |
|
949 | 949 | |
|
950 | 950 | - rebase everything on a branch marked by a bookmark onto the |
|
951 | 951 | default branch:: |
|
952 | 952 | |
|
953 | 953 | hg rebase --base myfeature --dest default |
|
954 | 954 | |
|
955 | 955 | - collapse a sequence of changes into a single commit:: |
|
956 | 956 | |
|
957 | 957 | hg rebase --collapse -r 1520:1525 -d . |
|
958 | 958 | |
|
959 | 959 | - move a named branch while preserving its name:: |
|
960 | 960 | |
|
961 | 961 | hg rebase -r "branch(featureX)" -d 1.3 --keepbranches |
|
962 | 962 | |
|
963 | 963 | - stabilize orphaned changesets so history looks linear:: |
|
964 | 964 | |
|
965 | 965 | hg rebase -r 'orphan()-obsolete()'\ |
|
966 | 966 | -d 'first(max((successors(max(roots(ALLSRC) & ::SRC)^)-obsolete())::) +\ |
|
967 | 967 | max(::((roots(ALLSRC) & ::SRC)^)-obsolete()))' |
|
968 | 968 | |
|
969 | 969 | Configuration Options: |
|
970 | 970 | |
|
971 | 971 | You can make rebase require a destination if you set the following config |
|
972 | 972 | option:: |
|
973 | 973 | |
|
974 | 974 | [commands] |
|
975 | 975 | rebase.requiredest = True |
|
976 | 976 | |
|
977 | 977 | By default, rebase will close the transaction after each commit. For |
|
978 | 978 | performance purposes, you can configure rebase to use a single transaction |
|
979 | 979 | across the entire rebase. WARNING: This setting introduces a significant |
|
980 | 980 | risk of losing the work you've done in a rebase if the rebase aborts |
|
981 | 981 | unexpectedly:: |

|
984 | 984 | singletransaction = True |
|
985 | 985 | |
|
986 | 986 | By default, rebase writes to the working copy, but you can configure it to |
|
987 | 987 | run in-memory for better performance. When the rebase is not moving the |
|
988 | 988 | parent(s) of the working copy (AKA the "currently checked out changesets"), |
|
989 | 989 | this may also allow it to run even if the working copy is dirty:: |
