The "InheritedProperties" page has been changed by pburba: http://wiki.apache.org/subversion/InheritedProperties?action=diff&rev1=24&rev2=25 Comment: Tweak the proposed svn propget and proplist changes so as to support a broader range of inheritance models. A child path that inherits a property from its parent may not have ready access to that parent in the working copy (e.g. the root of the working copy is a subtree of the parent path). To ensure that traditionally disconnected operations (i.e. those that require no access to the repository, like 'svn add') remain disconnected, we will maintain a cache of properties inherited by the root of the working copy. Whenever a new working copy is checked out, any properties inherited by the root of the working copy will be cached in the working copy. If a subtree within a working copy is switched, a separate cache will be created for the root of that subtree. Whenever an update occurs the cache(s) will be refreshed. The cache will be stored in a new wc-ng table: - ||||||||||<tablewidth="978px" tableheight="324px"style="font-weight:bold; ;text-align:center">TABLE: INHERITABLE_PROPS || + ||||||||||<tablewidth="978px" tableheight="324px"style="font-weight:bold; ;text-align:center">TABLE: INHERITABLE_PROPS || ||<style="font-weight:bold;">Name ||<style="font-weight:bold;">Data Type ||<style="font-weight:bold;">Primary Key ||<style="font-weight:bold;">Foreign Key ||<style="font-weight:bold;">Notes || ||wc_id ||integer ||Yes ||References NODES.WC_ID || || ||local_relpath ||text ||Yes ||References NODES.LOCAL_RELPATH || || @@ -117, +117 @@ * update (up): Updates the inherited properties cache(s). * upgrade: Creates an empty inherited properties cache, but doesn't populate it since that would require contacting the repository which upgrade shouldn't need to do. - Two subcommands, propget (pget, pg) and proplist (plist, pl), will support a new option enabling users to find inherited properties on a path: '--show-inherited-props'.

When used, any inherited properties for the target of the subcommand will be displayed. Inherited properties for subtrees of the target are not shown. For example: Given this repository structure with the explicit properties noted: {{{ - / svn:inheritable:foo=bar + / svn:inheritable:foo=bar - branches/ svn:inheritable:baz=qux + branch/ svn:inheritable:foo=bat, prop:baz=qux - branches/src/ + branch/src/ svn:inheritable:foo=bax - branches/src/foo.c + branch/src/pop.c - branches/inc + branch/inc - branches/inc/bar.h + branch/inc/pop.h trunk/ trunk/src/ - trunk/src/foo.c + trunk/src/pop.c trunk/inc - trunk/inc/bar.h + trunk/inc/pop.h }}} Without the --show-inherited-props option only explicit properties are shown (as has always been the case): {{{ - >svn pl -vR ^/branches + >svn pl -vR ^/branch - Properties on '%ROOT_URL%/branches': + Properties on '%ROOT_URL%/branch': - svn:inheritable:baz + svn:inheritable:foo + bat + prop:baz qux + Properties on '%ROOT_URL%/branch/src': + svn:inheritable:foo + bax - >svn pg -R svn:inheritable:baz ^/ + >svn pg -R svn:inheritable:foo ^/ + %ROOT_URL% - bar + %ROOT_URL%/branch - bat - %ROOT_URL%/branches - qux + %ROOT_URL%/branch/src - bax - >svn pg -v svn:inheritable:baz ^/trunk + >svn pg -v svn:inheritable:foo ^/branch - Properties on '%ROOT_URL%/branches': + Properties on '%ROOT_URL%/branch': + svn:inheritable:foo + bat + + >svn pg svn:inheritable:foo ^/trunk + + > + }}} + With the --show-inherited-props option, explicit properties are shown as normal, but any properties inherited by the target are also shown. For example, a recursive propget on ^/branch shows the explicit properties on the target and its children, but also shows that the target inherits svn:inheritable:foo from the root of the repository: + + {{{ + >svn pl -R --show-inherited-props ^/branch + Inheritable properties on '%ROOT_URL%': + svn:inheritable:foo + Properties on '%ROOT_URL%/branch': + svn:inheritable:foo + prop:baz + Properties on '%ROOT_URL%/branch/src': + svn:inheritable:foo + }}} + A target with no explicit mergeinfo might still inherit a property from a parent: + + {{{ + >svn pg -v --show-inherited-props svn:inheritable:foo ^/trunk + Inheritable properties on '%ROOT_URL%': svn:inheritable:foo bar - - >svn pg svn:inheritable:baz ^/trunk - - > }}} - With the --show-inherited-props option the inherited properties on the target are also shown: + If a path inherits a property from multiple parents, all the parents are shown: {{{ - >svn pl -R --show-inherited-props ^/branches - Properties on '%ROOT_URL%/branches': - svn:inheritable:baz - svn:inheritable:foo - - >svn pg -v --show-inherited-props svn:inheritable:baz ^/trunk + >svn pg -v --show-inherited-props svn:inheritable:baz ^/branch/src/pop.c - Properties on '%ROOT_URL%/branches': + Inheritable properties on '%ROOT_URL%': svn:inheritable:foo bar + Inheritable properties on '%ROOT_URL%/branch': + svn:inheritable:foo + bat + Inheritable properties on '%ROOT_URL%/branch/src': + svn:inheritable:foo + bax + }}} + If the target is a WC path and some of the inherited properties come from the repository, those from the repository are listed by URL rather than WC path: + + {{{ + >svn co %ROOT_URL%/branch branch-WC + A branch-WC\src + A branch-WC\src\pop.c + A branch-WC\inc + A branch-WC\inc\pop.h + U branch-WC + Checked out revision 11. + + >cd branch-WC + + >svn pg -vR svn:inheritable:foo + Inheritable properties on '%ROOT_URL%': + svn:inheritable:foo + bar + Properties on '.': + svn:inheritable:foo + bat + Properties on 'src': + svn:inheritable:foo + bax + }}} + The above examples apply only to custom user inheritable properties. Subversion reserved properties that we deem inheritable may exhibit differing behavior, depending on how we define inheritance merging for the property in question. For example, {{{svn pg svn:mergeinfo --show-inherited-props -v ^/branches/projX/src}}} would show either the explicit mergeinfo on {{{^/branches/projX/src}}} or the mergeinfo existing on {{{src's}}} nearest path-wise parent with explicit mergeinfo (or possible nothing if there was no explicit mergeinfo on the target or its parents). + + {{{#!wiki note + We may want to support different values for --show-inherited-props, possibly: + + --show-inherited-props=[ 'all' (default) | 'nearest' ] + + 'all' - Shows the target's explicit properties and all path-wise parents with inheritable properties. + + 'nearest' - Shows the target's explicit properties and the nearest path-wise parent for any properties which are *not* explicitly set on the target. This would be useful for seeing inheritable properties which follow a strict override model like svn:mergeinfo. }}} == API Changes == Rev svn_proplist_receiver_t to svn_proplist_receiver2_t, adding the argument apr_hash_t *'''inherited_prop_hash'''. Also allow the possibility that the existing apr_hash_t *prop_hash argument may be null:
