-[[tag patch]]
-
-This is my second cut at a feature like that requested here.
-It can also be found [here](http://ikidev.betacantrips.com/patches/move.patch).
-
-A few shortcomings exist:
-
-* No precautions whatsoever are made to protect against race conditions or failures
- in the rcs\_move function. I didn't even do the `cgi_editpage` thing where I hold
- the lock and render afterwards (mostly because the copy I was editing was not
- up-to-date enough to have that code). Although FAILED_SAVE is in movepage.tmpl,
- no code activates it yet.
-* Some code is duplicated between cgi\_movepage and cgi\_editpage, as well
- as rcs\_commit and rcs\_move.
-* The user interface is pretty lame. I couldn't figure out a good way to let
- the user specify which directory to move things to without implementing a
- FileChooser thing.
-* No redirect pages like those mentioned on [[todo/Moving_Pages]] exist yet,
- so none are created.
-* I added a Move link to page.tmpl but it may belong better someplace else --
- maybe editpage.tmpl? Not sure.
-* from is redundant with page so far -- but since the Move links could someday
- come from someplace other than the page itself I kept it around.
-* If I move foo.mdwn to bar.mdwn, foo/* should move too, probably.
-
-> Looks like a good start, although I agree about many of the points above,
-> and also feel that something needs to be done about rcses that don't
-> implement a move operation -- falling back to an add and delete.
-> --[[Joey]]
-
-Hmm. Shouldn't that be done on a by-RCS basis, though? (i.e. implemented
-by backends in the `rcs_move` function)
-
-> Probably, yes, but maybe there's a way to avoid duplicating code for that
-> in several of them.
-
-Also, how should ikiwiki react if a page is edited (say, by another user)
-before it is moved? Bail, or shrug and proceed?
-
-> The important thing is to keep in mind that the page could be edited,
-> moved, deleted, etc in between the user starting the move and the move
-> happening. So, the code really needs to deal with all of these cases in
-> some way. It seems fine to me to go ahead with the move even if the page
-> was edited. If the page was deleted or moved, it seems reasonable to exit
-> with an error.
