[postmodern-devel] cl-postgres/sbcl crashes with bogus stack frame
by david thompson 06 May '10

06 May '10

Any ideas what might trigger cl-postgres (postmodern 1.14) coming to its knees with the backtrace shown below? No error or condition description is given - sbcl (1.0.28) just retires from active duty and drops into the debugger with the ("bogus stack frame") indication. The postgresql server (8.3) log doesn't have any indication of trouble at the time cl-postgres seems to run into trouble. This seems to only happen intermittently (every few thousand queries), irreproducibly (doesn't seem to be associated with a specific query or anything along those lines), and only when the postgresql server is being utilized by several lisp instances concurrently. Thanks in advance for any input/ideas/troubleshooting suggestions... - Alan ... 32: ("bogus stack frame") 33: (SB-IMPL::SUB-SUB-SERVE-EVENT NIL NIL) 34: (SB-IMPL::SUB-SERVE-EVENT NIL NIL NIL) 35: (SB-SYS:WAIT-UNTIL-FD-USABLE 5 :INPUT NIL) 36: (SB-IMPL::REFILL-INPUT-BUFFER #<SB-SYS:FD-STREAM for "a socket" {C265BA9}>) 37: (SB-IMPL::INPUT-UNSIGNED-8BIT-BYTE #<SB-SYS:FD-STREAM for "a socket" {C265BA9}> T NIL) 38: (CL-POSTGRES::SKIP-BYTES #<unavailable argument> #<unavailable argument>) 39: (CL-POSTGRES::TRY-TO-SYNC #<SB-SYS:FD-STREAM for "a socket" {C265BA9}> T) 40: ((FLET #:CLEANUP-FUN-[FORM-FUN-[SEND-QUERY]389]390))[:CLEANUP] 41: (CL-POSTGRES::SEND-QUERY #<unavailable argument> #<unavailable argument> #<unavailable argument>) 42: ((LABELS #:G161)) 43: (SQLG::QUERY-CORE "select program from programs where programskey = '192828' ;" 20 #<unused argument>)

[postmodern-devel] Using simple-date date class as :col-type
by Mitch Berkson 25 Sep '09

25 Sep '09

I have not been successful using the date class as a :col-type in a DAO. Here is what I have tried: (defclass cpa-address () ((id :col-type integer :accessor address-id) (start_date :col-type date :accessor address-start-date) (version :col-type integer)) (:metaclass postmodern:dao-class) (:keys id) (:table-name gt_address)) In the Postgres database, the field type of start_date is date. When I select a cpa-address DAO, I expect to see a symbol of type simple-date in the start_date slot, but what I get is a CL universal time. Should I be trying something else to take advantage of simple-date? Thanks for any help. Mitch

[postmodern-devel] "defined more than once in table.lisp" warnings
by Mitch Berkson 24 Sep '09

24 Sep '09

When I run a select-dao, the REPL prints a bunch of warnings like: Warning: (METHOD UPDATE-DAO (CPA-SERIES)) defined more than once in d:\lisp\postmodern\postmodern\table.lisp. Is this something I can fix? Thanks for any help. Mitch

[postmodern-devel] Error if SSL and no client cert and key files specified
by Mitch Berkson 05 Sep '09

05 Sep '09

If I call make-ssl-stream with *ssl-key-file* and *ssl-certificate-file* both nil, I get the following error: Error: A failure in the SSL library occurred on handle #<Pointer to type :VOID = #x02600208>. (Return code: 1)SSL error queue: error:140C5042:SSL routines:SSL_UNDEFINED_FUNCTION:called a function you should not call Does this mean that it's not possible to make a unilateral SSL connection? Should there be a more user-friendly error message? Thanks for any help. Mitch
