As suggested by Garrett Rooney, here is the Phase 1 patch again without a custom
typedef for the keyword hashes. Otherwise it is unchanged from the first pass.
John
=================
Implement printf-like format characters for keyword expansion. See
Issue #890 for further information.
* includes/svn_subst.h:
(svn_subst_build_keywords2): Interface change. A new argument
apr_hash_t *props.
(svn_subst_build_keywords): API compatibility wrapper for previous
(svn_subst_keywords_differ2): Interface change. A new argument
apr_pool_t *pool.
(svn_subst_keywords_differ): API compatibility wrapper for previous
(svn_subst_copy_and_translate2): Interface change; hash instead of struct
(svn_subst_copy_and_translate): API compatibility wrapper for previous
(svn_subst_translate_stream2): Interface change; hash instead of struct
(svn_subst_translate_stream): API compatibility wrapper for previous
* includes/svn_types.h:
Define keyword format string for Revision, Date, Author, URL, ID
* libsvn_subr/svn_subst.c:
(keyword_printf): New private function; printf-style formatting of
keywords based on format strings
(keywords_to_keyhash): New private function; convert keywords struct into
keywords hash
(keyhash_to_keywords): New private function; convert keywords hash into
keywords struct
(svn_subst_build_keywords): API combatibility wrapper
(svn_subst_build_keywords2): Build keywords using keyword_printf().
(translate_keyword): Interface changes. It now looks up keyword
passed in buffer, instead of predefined constant string.
(svn_subst_translate_stream): API combatibility wrapper
(svn_subst_translate_stream2): Loop over all elements of keyword hash
instead of structure elements.
(svn_subst_keywords_differ): API combatibility wrapper
(svn_subst_keywords_differ2): Compare two hashes instead of comparing
individual structure elements.
(svn_subst_copy_and_translate): API combatibility wrapper
(svn_subst_copy_and_translate2): uses keywords hash instead of struct
