Hi!

i found a problem while playing with TalkFFI generation of MySQL( yes, thats probably not the path we are going to take but i am doing init to learn).

The generation throws a problem with the following struct.

typedef struct my_collation_handler_st

{

� my_bool (*init)(struct charset_info_st *, void *(*alloc)(size_t));

� /* Collation routines */

� int � � (*strnncoll)(struct charset_info_st *,

� � � const uchar *, size_t, const uchar *, size_t, my_bool);

� int � � (*strnncollsp)(struct charset_info_st *,

� � � � � � � � � � � � �const uchar *, size_t, const uchar *, size_t,

� � � � � � � � � � � � �my_bool);

� size_t � � (*strnxfrm)(struct charset_info_st *c,

� � � � � � � � � � � � �uchar *a, size_t g, const uchar *b, size_t h);

� size_t � �(*strnxfrmlen)(struct charset_info_st * aa, size_t bb);

� my_bool (*like_range)(struct charset_info_st *,

const char *s, size_t s_length,

pchar w_prefix, pchar w_one, pchar w_many,�

size_t res_length,

char *min_str, char *max_str,

size_t *min_len, size_t *max_len);

� int � � (*wildcmp)(struct charset_info_st *,

� � � const char *str,const char *str_end,

� � � � � � � � � � �const char *wildstr,const char *wildend,

� � � � � � � � � � �int escape,int w_one, int w_many);

� int �(*strcasecmp)(struct charset_info_st *, const char *, const char *);

��

� uint (*instr)(struct charset_info_st *,

� � � � � � � � const char *b, size_t b_length,

� � � � � � � � const char *s, size_t s_length,

� � � � � � � � my_match_t *match, uint nmatch);

��

� /* Hash calculation */

� void (*hash_sort)(struct charset_info_st *cs, const uchar *key, size_t len,

� �ulong *nr1, ulong *nr2);�

� my_bool (*propagate)(struct charset_info_st *cs, const uchar *str, size_t len);

} MY_COLLATION_HANDLER;

As you can see the struct has eleven fields which are functions pointers. However, when we generate with TalkFFI it s fails, and we can see that the struct generate is the following:

an OrderedCollection(

� #MySQLMySysH25Cb->'init'�

� #MySQLMySysH26Cb->'strnncoll'�

� #MySQLMySysH26Cb->'strnncollsp'�

� {#NBInt32. {'NBInt32 *'->'arg1'}}->'size_t'�

� #MySQLMySysH27Cb->'like_range'�

� #MySQLMySysH28Cb->'wildcmp'�

� #MySQLMySysH6Cb->'strcasecmp'�

� #MySQLMySysH29Cb->'instr'�

� #MySQLMySysH30Cb->'hash_sort'�

� #MySQLMySysH31Cb->'propagate'

)

The generate struct have only ten fields and the fourth is wrongly generated. Instead of the two fields �strnxfrm and strnxfrmlen , it generates garbage.

We were with guille debugging and playing with the struct declaration with not much results.

Thanks for any help rochi and guille.
