Database Independent Abstraction Layer

File Release Notes and Changelog

Release Name: libdbi-0.8.3

Notes:
libdbi 0.8.3 (the "Steeltown" release)

Bugfixes

- database engine client libraries which install exit handlers are not
  safe to unload on some systems. libdbi now checks the driver
  capability "safe_dlclose" and unloads the driver only if the driver
  claims it is safe to do so.

Improvements

- three functions were added: dbi_conn_escape_string(),
  dbi_conn_escape_string_copy(), and dbi_conn_escape_binary_copy()
  perform the same escaping of special characters as the corresponding
  *_quote_* functions do, but they do not surround the resulting
  string with quotes. This may at times be more convenient if the
  escaped strings are not directly inserted into a SQL query.

- error handling and reporting was changed once again. The
  dbi_conn_error_flag() function is now deprecated. Instead, a call of
  dbi_conn_error() is all it takes to check the error status. This
  function returns zero if the last operation was successful, < 0 (one
  of several predefined libdbi error codes) for internal errors, and > 0
  for client library errors. To maintain backwards compatibility,
  dbi_conn_error_flags() reports the same error codes as
  dbi_conn_error() so older code should not break as long as you checked
  against the predefined error codes.

- deprecated functions will now cause compiler warnings to make you
  aware of this fact. This does not negatively affect your programs
  but it kindly reminds you of the fact that right now is a good time to
  modify your sources.
