Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Subversion Wiki" fo=
r change notification.

The "MultiLayerMoves" page has been changed by PhilipMartin:

ev2=3D17

  =

  There is only one move recorded C/F->C/G.  The move inside the copy is re=
corded in a similar way to the move inside a move.

+ Move has to rewrite moved-to both inside an outside the moved tree. The f=
irst case is moved-to entirely within the moved tree: move A to B after A/F=
 to A/G.  This causes moved-to on A/F to be rewritted (to null) and moved-t=
o on B/F to be added:
+ =

+ || op-depth || local-relpath || presence     || moved-to ||
+ ||    0     ||    A          || normal       ||          ||
+ ||    0     ||    A/F        || normal       ||          ||
+ ||    2     ||    A/F        || base-deleted ||   A/G    ||
+ ||    2     ||    A/G        || normal       ||          ||
+ =

+ || op-depth || local-relpath || presence     || moved-to ||
+ ||    0     ||    A          || normal       ||          ||
+ ||    0     ||    A/F        || normal       ||          ||
+ ||    1     ||    A          || base-deleted ||    B     ||
+ ||    1     ||    A/F        || base-deleted ||          ||
+ ||    1     ||    B          || normal       ||          ||
+ ||    1     ||    B/F        || normal       ||          ||
+ ||    2     ||    B/F        || base-deleted ||    B/G   ||
+ ||    2     ||    B/G        || normal       ||          ||
+ =

+ The second case is moved-to from inside the moved-tree to outside the mov=
ed tree: move A to B after A/F to G. Like the first case this requires the =
moved-to on A/F to be rewritten (to null) and moved-to on B/F to be added. =
Compared to the first case the value of the rewritten moved-to doesn't chan=
ge:
+ =

+ || op-depth || local-relpath || presence     || moved-to ||
+ ||    0     ||    A          || normal       ||          ||
+ ||    0     ||    A/F        || normal       ||          ||
+ ||    2     ||    A/F        || base-deleted ||   G      ||
+ ||    1     ||    G          || normal       ||          ||
+ =

+ || op-depth || local-relpath || presence     || moved-to ||
+ ||    0     ||    A          || normal       ||          ||
+ ||    0     ||    A/F        || normal       ||          ||
+ ||    1     ||    A          || base-deleted ||   B      ||
+ ||    1     ||    A/F        || base-deleted ||          ||
+ ||    1     ||    B          || normal       ||          ||
+ ||    1     ||    B/F        || normal       ||          ||
+ ||    2     ||    B/F        || base-deleted ||   G      ||
+ ||    1     ||    G          || normal       ||          ||
+ =

+ The third case is move-to from outside the moved tree into the moved tree=
: move A to B after F to A/F. This causes moved-to on F, outside the moved =
tree, to be rewritten:
+ =

+ || op-depth || local-relpath || presence     || moved-to ||
+ ||    0     ||    A          || normal       ||          ||
+ ||    0     ||    F          || normal       ||          ||
+ ||    1     ||    F          || base-deleted ||   A/G    ||
+ ||    2     ||    A/G        || normal       ||          ||
+ =

+ || op-depth || local-relpath || presence     || moved-to ||
+ ||    0     ||    A          || normal       ||          ||
+ ||    0     ||    F          || normal       ||          ||
+ ||    1     ||    A          || base-deleted ||   B      ||
+ ||    1     ||    F          || base-deleted ||   B/G    ||
+ ||    1     ||    B          || normal       ||          ||
+ ||    2     ||    B/G        || normal       ||          ||
