+This is the header of the cadabra source file.
+
+
+;;;; a CMUCL/OCI implementation of a subset of the DBI interface
+;;;;
+;;;; The original version of this code was copyright (c) 1999-2000 Cadabra Inc.
+;;;; It was placed in the public domain by Cadabra in January 2000.
+;;;;
+;;;; The implementors of the original version were Winton Davies
+;;;; <wdavies@cadabra.com> and William Newman <william.newman@airmail.net>.
+;;;; The code will be maintained by Winton Davies.
+
+;;;; known issues:
+;;;; * The code will leak C resources if errors occur in the the wrong
+;;;; places, since it doesn't wrap its allocation/deallocation
+;;;; logic in the necessary EVAL-WHENs to prevent this. (This could be
+;;;; easily be an issue for long-running processes which recover from
+;;;; database errors instead of simply terminating when they occur. It's
+;;;; not an issue for programs which consider database errors so abnormal
+;;;; that they die immediately when they encounter one.)
+;;;; * Instead of reading Oracle header files automatically, this code
+;;;; uses constants, types, and function signatures manually transcribed
+;;;; from the Oracle header files. Thus, changes in the header files
+;;;; may require manual maintenance of the code. (This version was written
+;;;; for Oracle 8.1.5.)
+;;;; * various KLUDGEs noted in the code
+
+;;;; log:
+;;;; 6. * moved test suite to separate file
+;;;; * removed trailing spaces from all strings returned from database
+;;;; * fixed error in LIST-ALL-DATABASE-TABLES interface: DB should be
+;;;; a &KEY argument, not an &OPTIONAL argument
+;;;; 7. * merged Winton's code to allow the SQL function to ask OCI
+;;;; whether an operation returns a table, and not to worry about
+;;;; the TYPE keyword argument if no table is returned
+;;;; * reduced +N-BUF-ROWS+ from 1000 to reduce probability of
+;;;; hitting CMUCL 18b 8Mb-of-C-data limit
+;;;; * changed NOT-USED argument of FETCH-ROW to EOF-ERRORP, to
+;;;; conform to Allegro interface
+;;;; * found apparent bug in OCI (wrong size of value returned for the
+;;;; +oci-attr-data-size+ attribute); added workaround
+;;;; * found and documented the unnecessariness of "workaround" for
+;;;; "WITH-ALIEN not working" (which was actually a conceptual error
+;;;; on WHN's part, expecting WITH-ALIEN to work the same way as
+;;;; MAKE-ALIEN, not expecting one less level of indirection)
+;;;; * cleaned up NULLS-OK-USE-THIS-ERRHP weirdness and inflexibility,
+;;;; splitting the one argument into separate NULLS-OK and ERRHP
+;;;; arguments
+;;;; * added :ERRHP optional arguments to various OERR expressions,
+;;;; so that now failures are more likely to generate informative
+;;;; error messages instead of just "OCI Error (and no ERRHP
+;;;; available to find subcode)"
+;;;; 8. * added code to deallocate C resources
+;;;; 9. * Added in an extra field for DATE-FORMAT and DATE-FORMAT-LENGTH
+;;;; Munged the code for datatype and colsize. Winton Davies.
+;;;; 10. * cleaned up remnants of old date-is-fixed-length-field design
+;;;; assumption, getting rid of +OCi-date-bytes+
+;;;; * reduced consing in FETCH-ROW and associated functions
+;;;; * replaced WARN with IWARN for implementor-only warnings
+;;;; 11. * fixed bad (THE (ALIEN (* FLOAT)) B) declaration for
+;;;; SQLT_FLT buffers (should be (ALIEN (* DOUBLE)) instead;
+;;;; and for some reason fell through the cracks of CMUCL's
+;;;; "declarations are assertions" principle)
+;;;; * deleted various FIXME notes a la "does this code ever get
+;;;; exercised?" and "are these really all the cases we need?"
+;;;; * changed the IWARN call to a KLUDGE comment, deleted IWARN
+;;;; * tidied up comments
+;;;; * changed page breaks from lots-of-semicolons Cadabra style
+;;;; to ^L CMUCL style
+;;;; * declared DBI-ERROR to be INLINE
+;;;; * fixed definition of +oci-htype-env+
+;;;; * reviewed and corrected C resource deallocation code
+;;;; 12. * Made load-foreign depend on ORACLE-HOME for more portability.

+;;;; about the behavior of MAKE-ALIEN and WITH-ALIEN; I thought that
+;;;; (MAKE-ALIEN TYPEFOO) returned the same type of object as is bound
+;;;; to the name BAR by (WITH-ALIEN ((BAR TYPEFOO)) ..). In fact the

+;; the hairy part of MAKE-QUERY-CURSOR: Ask OCI for information
+;; about table columns, translate the information into a Lisp
+;; vector of column descriptors, and return it.
+
+;; Allegro defines several flavors of type conversion, but this
+;; implementation only supports the :AUTO flavor.
+
+;; A note of explanation: OCI's internal number format uses 21
+;; bytes (42 decimal digits). 2 separate (?) one-byte fields,
+;; scale and precision, are used to deduce the nature of these
+;; 21 bytes. See pp. 3-10, 3-26, and 6-13 of OCI documentation
+;; for more details.
+
+;; When calling OCI C code to handle the conversion, we have
+;; only two numeric types available to pass the return value:
+;; double-float and signed-long. It would be possible to
+;; bypass the OCI conversion functions and write Lisp code
+;; which reads the 21-byte field directly and decodes
+;; it. However this is left as an exercise for the reader. :-)
+
+;; The following table describes the mapping, based on the implicit
+;; assumption that C's "signed long" type is a 32-bit integer.
+;;
+;; Internal Values SQL Type C Return Type
+;; =============== ======== =============
+;; Precision > 0 SCALE = -127 FLOAT --> double-float
+;; Precision > 0 && <=9 SCALE = 0 INTEGER --> signed-long
+;; Precision = 0 || > 9 SCALE = 0 BIG INTEGER --> double-float
+;; Precision > 0 SCALE > 0 DECIMAL --> double-float
+
+;; (OCI uses 1-based indexing here.)
+
+;; KLUDGE: This should work for all other data types except those
+;; which don't actually fit in their fixed-width field (BLOBs and the
+;; like). As Winton says, we (Cadabra) don't need to worry much about
+;; those, since we can't reason with them, so we don't use them. But
+;; for a more general application it'd be good to have a more
+;; selective and rigorously correct test here for whether we can
+;; actually handle the given DEREF-DTYPE value. -- WHN 20000106
+
+;; Note: The OCI documentation doesn't seem to say whether the COLNAME
+;; value returned here is a newly-allocated copy which we're
+;; responsible for freeing, or a pointer into some system copy which
+;; will be freed when the system itself is shut down. But judging
+;; from the way that the result is used in the cdemodsa.c example
+;; program, it looks like the latter: we should make our own copy of
+;; the value, but not try to free it.
+
+;; WORKAROUND: OCI seems to return ub2 values for the
+;; +oci-attr-data-size+ attribute even though its documentation claims
+;; that it returns a ub4, and even though the associated "sizep" value
+;; is 4, not 2. In order to make the code here work reliably, without
+;; having to patch it later if OCI is ever fixed to match its
+;; documentation, we pre-zero COLSIZE before making the call into OCI.
+
+;; To exercise the weird OCI behavior (thereby blowing up the code
+;; below, beware!) try setting this value into COLSIZE, calling OCI,
+;; then looking at the value in COLSIZE. (setf colsize #x12345678)
