# Problem surfaces when using FreeTDS, ASE 12.5 and reading text fields
# with NULL values. This is essentially a workaround for a bug in Free-
# TDS which is not setting the NULL indicators correctly, but provides
# a protection against possible segfaults if any other driver ever does
# this again:-)
# [DOC] If a second call is made to sybase_connect() with the same arguments
# no new link will be established, but instead, the link identifier of the
# already opened link will be returned. The new parameter modifies this
# behavior and makes sybase_connect() always open a new link, even if
# sybase_connect() was called before with the same parameters.
- Fixed bug #27843 (sybase_query() triggers (spurious?) notices when
query is a stored procedure)
- Fixed multiple memory leaks with sybase_unbuffered_query()
- Changed sybase_query() to ignore store_results = false in buffering
mode, it would yield unpredictable results
- Fixed sybase_unbuffered_query() when used with store_results = false
- Changed sybase_fetch_object() to ignore second argument when passed
as NULL
- Made sybase_data_seek() error message more verbose
- Fixed memory leak in shutdown when not all rows where selected in an
unbuffered query
used to return "" and not bool(false). It's not worth keeping it because
STR_FREE() and zval_dtor() always have to check for it and it slows down
the general case. In addition, it seems that empty_string has been abused
quite a lot, and was used not only for setting zval's but generally in
PHP code instead of "", which wasn't the intention. Last but not least,
nuking empty_string should improve stability as I doubt every place
correctly checked if they are not mistakenly erealloc()'ing it or
calling efree() on it.
NOTE: Some code is probably broken. Each extension maintainer should
check and see that my changes are OK. Also, I haven't had time to touch
PECL yet. Will try and do it tomorrow.

@- Made sybct.login_timeout changeable at runtime (Timm)
@- Added ini option sybct.packet_size which lets you control the packet
