New Revision: 1632868
URL: http://svn.apache.org/r1632868
Log:
Move the FSFS index load logic into FSFS.
* subversion/include/private/svn_fs_fs_private.h
(svn_fs_fs__load_index): Declare new API, taken from load-index-cmd.c.
Extend docstring.
* subversion/libsvn_fs_fs/load-index.c
(): New file. Update #includes.
(svn_fs_fs__load_index): Moved here from load-index-cmd.c.
* subversion/svnfsfs/load-index-cmd.c
(): Update #includes.
(svn_fs_fs__load_index): Remove here.
