Julian Foad commented on SVN-4781:
----------------------------------
[r1700966|http://svn.apache.org/r1700966] added the following code to
1.10.x/subversion/bindings/swig/include/svn_types.swg:
{quote}{{%typemap(in,warning="901:FIXME: Missing old_value_p typemap") const
svn_string_t *const *old_value_p {}}
{{#if defined(SWIGRUBY) && SWIG_VERSION <= 0x010329}}
{{ /* Ruby fails to define $symname. */}}
{{ SWIG_exception(SWIG_ValueError, "Function is not implemented yet");}}
{{#else}}
{{ SWIG_exception(SWIG_ValueError, "$symname is not implemented yet");}}
{{#endif}}
{{}}}
{quote}
which changed the generated bindings like this:
{quote}{{--- 1.9.x/obj-dir/subversion/bindings/swig/python/svn_ra.c}}
{{+++ 1.10.x/obj-dir/subversion/bindings/swig/python/svn_ra.c}}
