From: Marcus Wanner Date: Sat, 19 Nov 2011 01:42:10 +0000 (-0500) Subject: Change the arbitrary URI support from implied to explicit X-Git-Url: https://git.rkrishnan.org/components/com_hotproperty/module-simplejson.decoder.html?a=commitdiff_plain;h=e58a01270b6b754f1c76b4640f9813049ce1c783;p=tahoe-lafs%2Ftahoe-lafs.git Change the arbitrary URI support from implied to explicit The move webapi function now takes a target_type argument which lets it know whether the target is a subdirectory name or URI. This is an improvement over the old system in which the move handler tried to guess whether the target was a name or a URI. Also fixed a little docs copypaste problem and tweaked some line wrapping. --- diff --git a/docs/frontends/webapi.rst b/docs/frontends/webapi.rst index 5f1060b1..11cee722 100644 --- a/docs/frontends/webapi.rst +++ b/docs/frontends/webapi.rst @@ -1281,16 +1281,21 @@ Renaming A Child Moving A Child ---------------- -``POST /uri/$DIRCAP/[SUBDIRS../]?t=rename&from_name=OLD&to_dir=TARGET[&to_name=NEW]`` +``POST /uri/$DIRCAP/[SUBDIRS../]?t=move&from_name=OLD&to_dir=TARGET`` This instructs the node to move a child of the given directory to a - different directory, both of which must be mutable.
