Subject svn commit: r1547042 - in /subversion/branches/fsfs-ucsnorm: BRANCH-README subversion/libsvn_fs_fs/fs.h subversion/libsvn_fs_fs/fs_fs.c
Date Mon, 02 Dec 2013 14:52:00 GMT
Author: brane

New Revision: 1547042

URL: http://svn.apache.org/r1547042
Log:
On the fsfs-ucsnorm branch: Rename the normalization option in fsfs.conf,
add parsing code, and clarify semantics in BRANCH-README.

* BRANCH-README: Update the documented semantics of the proposed change.

* subversion/libsvn_fs_fs/fs.h (CONFIG_OPTION_NORMALIZED_LOOKUP):
   Renamed from CONFIG_OPTION_ENABLE_NORMALIZED_LOOKUP.
  (SVN_FS_FS__MIN_DEFAULT_NORMALIZED_LOOKUP_FORMAT): New. Normalization
   will be enabled by default in FSFSv7 and above.
  (fs_fs_data_t): New member 'normalized_lookup'.
* subversion/libsvn_fs_fs/fs_fs.c (read_config):
   Parse the normalized-lookup option into the fs_fs_data_t stuct.
  (write_config): Update normalization doc and option name.
