Julian Foad commented on SVN-4786:
----------------------------------
The new API svn_client__wc_editor() is in place.
The difficult part is handling the 'copy file' and especially 'copy directory'
methods, as the WC requires to fetch the bases of the copied things but doesn't
have a clean way to receive them.
The new API svn_client__repos_to_wc_copy()is beginning to encapsulate this
'copy' functionality. Presently it inherits the existing ugly 'perform a
checkout' implementation when copying a directory.

> Create a delta-editor that applies working modifications to the WC.
> It will be useful for implementing things such as shelving, which in
> principle (and, with this in place, more easily in practice) are just copying
> a set of modifications from WC to shelf and from shelf to WC.
> Use it to implement the existing client modifications ('svn add', 'svn copy',
> 'svn rm', etc.). Why? (1) ensure it works for and fully supports those cases;
> (2) ensure those cases are handled consistently (it will probably reveal
> inconsistencies in the old implementation).
> See dev@ thread "Crazy idea: changes in WC should share an API with changes
> in repository", from Julian Foad, 2018-11-09.
