[libdbi-devel] serious bug in dbi_result_get_string_idx()

[Markus H. <mar...@mh...>]

Hi there,

I've found a serious bug in dbi_result_get_string_idx(). libdbi erroneously
returns a NULL string if the database contains an empty string. SQL mandates
that NULL is distinct from '', therefore the current version of libdbi may
cause data corruption. Affected are dbi_result_get_string_idx() and
dbi_result_get_string() which calls the former.

The fix is ridiculously trivial, see my last two checkins of src/dbi_result.c
(the second patch only fixes a misleading comment in the first one). I think we
should release 0.8.1 as soon as possible. Are there any other minor changes
necessary that should be included into this release?

regards
Markus
