Make sure we consume the ReadyForQuery packet that is generated when closing a prepared statement or portal, or the packet can be misinterpreted by a later query, leading to data loss. Fix from Robert J. Macomber. darcs-hash:7ef83e38bdbd39d64bf602a5bfa60133234b743c

Add an ABORT keyword argument to PG-DISCONNECT (from Robert J. Macomber <pgsql@rojoma.com>), as per CL:CLOSE. "I've run into a problem with pg-disconnect if something abnormal happens to the database connection -- if the database goes away for a restart while pg has a connection open, for example. When this happens, pg-disconnect fails, and the socket file descriptor is left open (presumably for a finalizer to clean up), also raising a new error from the unwind-protect in with-pg-connection. To guard against the possibility, I've added an :abort parameter to pg-disconnect, like cl:close has, and made with-pg-connection call it with :abort t if the body exits abnormally, in the same way that with-open-file operates. When :abort is true, the modified pg-disconnect closes the database connection ungracefully, including making the close call abort (otherwise, sbcl at keast tries to flush the stream, raising another error if the database isn't there anymore)." darcs-hash:aad628cf0093846dca55fe4f8fa47b0db89249c2

Allow encoding used for socket communication with the backend to be specified as a keyword argument to PG-CONNECT, for cases where rebinding *PG-CLIENT-ENCODING* is inconvenient.

Fixes to the prepared statement support, in order to implement precise error reporting. Deadlocks were possible with previous version, where pg-dot-lisp would be blocked waiting for input from the backend that never arrived. Also some code cleanups. darcs-hash:0588a2f36bb19982641cd4e7f147578e669feb59

Make PGLO-READ a generic function, with specializations on the v2 and v3 protocols. The difference is necessary because the v2 protocol reads large-object data in text, whereas the v3 protocol changed to use a binary format. darcs-hash:6639fd1b9dd10ca051ea03d7e2fbff94c0d917e2

Three fixes from Björn Lindberg <d95-bli@nada.kth.se>: - Two trivial bugs with regards to use with Allegro - Handling of the special timestamp values infinity and -infinity. They gave an error, but now returns the symbols :INFINITY and :-INFINITY respectively. - A bug in the version 3 of the protocol, where it would return NIL for fields in the database containing the empty string, rather than an empty string. darcs-hash:504e8e152c17d5b4a0d4aa402c8fe52e71647eef

Implement binary-mode transfers for large-object operations in the v3 protocol. The v2 protocol transfers arguments in binary mode, but the v3 protocol requires the client to specify for each argument of a FunctionCall whether it is encoded as binary or as text. - add possibility to send (unsigned-byte 8) arguments to function calls - add a method READ-OCTETS-FROM-PACKET that reads raw octets - make PG-IMPORT and PG-EXPORT use binary I/O - PGLO-READ reads data in binary - change the large-object tests to use binary I/O (fixes the pglo test) darcs-hash:bda38e377fe3d2bf89d34065e942299e065fdd90

Comment-only patch: mark the places in the v3-protocol code where charset encoding problems will have to be addressed. It's probably not worth going through the v2-protocol code to fix these issues, since it has too many places where READ-CSTRING is confused with READ-OCTET-ARRAY. darcs-hash:9571ebcd90ed9e3e9fb4d92f13594bdb1dd0f5c4

A provisional fix for large object support: the test case (whose large-object component only runs on CMUCL) was resetting the connection during the IMPORT/EXPORT test, due to an unexpected #\V packet (FunctionCallResponse) in DO-FOLLOWUP-QUERY. It's still not clear why a FunctionCallResponse should be received anywhere other than in FN. This test is currently failing due to CR -> "\012" corruption that I haven't debugged. darcs-hash:5068c028cbcd6cc537dc5cb7b506615c652636ad

- add md5 authentication (thanks to Brian Mastenbrook). Uses Pierre Mai's portable md5.lisp library, that has been added to the project (with extra EVAL-WHENness to please OpenMCL and ACL). Tested with CMUCL, SBCL, OpenMCL, CLISP, ACL 6.1. ABCL does not compile md5.lisp, probably for more EVAL-WHEN reasons. Only tested with PostgreSQL version 7.4. darcs-hash:76581bd5b619a8e593164743a8ff044357c680cb

Integrate Peter Van Eynde's v3 protocol support: - create PGCON-V2 and PGCON-V3 classes - PG-CONNECT attempts to connect using v3 protocol, and falls back to v2 protocol for older backends; return a PGCON-V2 or PGCON-V3 object - PG-EXEC and FN and PG-DISCONNECT are generic functions that dispatch on the connection type - protocol code split into v2-protocol.lisp and v3-protocol.lisp TBD: cleaning up the notification & error reporting support, and factorizing more code between the two protocol versions. Also split code out into multiple files: - large-object support - metainformation about databases - parsing and type coercion support - utility functions and macros darcs-hash:00b6e900f7b48953d959f95e55c26ecee52efb37
