Message Author: julianfoad
Date: Fri Jan 9 02:04:35 2009
New Revision: 35103

Log:
In the "checksums" API, make the svn_checksum_t type opaque to help make
future extensions easier, and introduce accessor functions:
  svn_checksum_get_kind()
  svn_checksum_get_size() (replacing svn_checksum_size())
  svn_checksum_get_digest()
to replace direct access.

Make the constructor "svn_checksum__from_digest()" public as well by
renaming it to "svn_checksum_from_digest()", because it is the logical
complement of the "get" accessors.

* subversion/include/s​vn_checksum.h,
  subversion/libsvn_su​br/checksum.c
  (svn_checksum_t): Move the definition from the header to the source file,
    leaving just a declaration in the header. Make the "digest" field
    non-const and remove all the type casts that were used to write to it
    throughout the rest of this source file.
  (svn_checksum_size): Rename to ...
  (svn_checksum_get_size): ... this and add "const" on the input parameter.
  (svn _checksum_get_kind, svn_checksum_get_digest): New functions.
  (svn_checksum__from_digest): Rename to ...
  (svn_checksum_from_digest): ... this.

* subversion/libsvn_cl​ient/commit.c,
  subversion/libsvn_cl​ient/commit_util.c,
  subversion/libsvn_cl​ient/export.c,
  subversion/libsvn_de​lta/text_delta.c,
  subversion/libsvn_fs​_base/bdb/checksum-r​eps-table.c,
  subversion/libsvn_fs​_base/bdb/dbt.c,
  subversion/libsvn_fs​_base/dag.c,
  subversion/libsvn_fs​_base/reps-strings.c​,
  subversion/libsvn_fs​_base/tree.c,
  subversion/libsvn_fs​_base/util/fs_skels.​c,
  subversion/libsvn_fs_fs/dag.c,
  subversion/libsvn_fs​_fs/fs_fs.c,
  subversion/libsvn_fs​/fs-loader.c,
  subversion/libsvn_fs​_fs/rep-cache.c,
  subversion/libsvn_fs_fs/tree.c,
  subversion/libsvn_subr/io.c,
  subversion/libsvn_su​br/stream.c,
  subversion/libsvn_wc​/adm_crawler.c,
  subversion/libsvn_wc/adm_ops.c,
  subversion/libsvn_wc​/update_editor.c
    Adjust for the renaming of svn_checksum__from_digest().
    Use the accessor functions instead of direct access.

* subversion/libsvn_su​br/svn_base64.c
  (svn_base64_from_checksum):
    Use the accessor functions instead of direct access.
  (svn_base64_from_md5): Use svn_checksum__from_digest to simplify and avoid
    direct write access to a checksum.

* subversion/tests/lib​svn_delta/window-tes​t.c
  (stream_window_test): Use svn_checksum_from_digest() to simplify and avoid
    direct write access to a checksum.
