Your patch for svn_string.i was almost exactly what I posted a month ago. :-)
(There was more to my patch, but that was the good acceptable part.)
However, doesn't that just always reduce it down to the OTHER type of problem?
I see you hacked around one specific case in svn_fs.i, but what about any others?
As of Jan 31, the affected functions that had "const char **" args were:
That list might be slightly different now.
Isn't this really a general case problem anyway?
As in, SWIG doesn't correctly handle functions that return NULL valued pointers as their first
Ultimately this sounds like something that should be fixed in SWIG, not hacked around in
Subversion (even though that may be necessary in the short term.)
So if Subversion is going to hack around it, wouldn't it be better to have a general solution that
works in every case rather than hack it one arg list at a time? I would argue that this is
exactly what Dale (and myself to some extent) seemed to be getting to.
This same problem can and and I am sure will affect types other than "const char **".
I guess I am looking for your feelings on the overall status of this. Do you consider this a case
closed, or something that still needs attention? Should any more attention be given here, or
should someone start a SWIG crusade?
