Subject svn commit: r1853816 - /subversion/branches/shelving-v3/subversion/libsvn_client/shelf.c
Date Mon, 18 Feb 2019 18:10:05 GMT
Author: julianfoad

New Revision: 1853816

URL: http://svn.apache.org/viewvc?rev=1853816&view=rev
Log:
On the 'shelving-v3' branch: copy WC base using 'checkout' instead of 'cp -r'.

For now, this completely ignores the mixed-rev, switched-URL,
mixed-depth WC state, and performs a simple checkout from the repo.
Eventually it will need to recreate the exact base state, and will need to
read data from the user's WC instead of the repo for fast local operation.

* subversion/libsvn_client/shelf.c
  (shelf_copy_base): Create shelf base WC by a simple checkout.
