Subject svn commit: r1652496 - in /subversion/trunk/subversion/libsvn_fs_x: cached_data.c transaction.c util.c util.h
Date Fri, 16 Jan 2015 19:20:55 GMT
Author: stefan2
Date: Fri Jan 16 19:20:55 2015
New Revision: 1652496

URL: http://svn.apache.org/r1652496
Log:
Deal with the last set of path constructors in FSX.  The temporary strings
they create cannot be eliminated reasonably, therefore swtich the functions
to using two pools and update the callers.

* subversion/libsvn_fs_x/util.h
  (svn_fs_x__path_txn_node_rev,
   svn_fs_x__path_txn_node_props,
   svn_fs_x__path_txn_node_children): Switch signature to using two pools

* subversion/libsvn_fs_x/util.c
  (construct_txn_node_path): New path construction utility.
  (svn_fs_x__path_txn_node_rev,
   svn_fs_x__path_txn_node_props,
   svn_fs_x__path_txn_node_children): Simplify by calling the new utility.
                                      Now use two pool parameters.

* subversion/libsvn_fs_x/cached_data.c
  (get_node_revision_body,
   get_dir_contents,
   svn_fs_x__get_proplist): Update callers.

* subversion/libsvn_fs_x/transaction.c
  (svn_fs_x__put_node_revision,
   svn_fs_x__set_entry,
   svn_fs_x__set_proplist,
   svn_fs_x__delete_node_revision): Same.
