[postmodern-devel] cl-postgres/sbcl crashes with bogus stack frame
by david thompson 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>)

Hi I am trying to figure out how to exclude certain slots when persisting the dao instance to the db short of making a new object with the limited range of slots. Any ideas or advise? Thanx

[postmodern-devel] Date Problem
by Phil Marneweck 04 Nov '09

I get different date formats back from a postmodern query at different times. I am using SBCL 1.0.31.32 and the latest (as of the weekend) from clbuild. The steps. 1. I delete all my .fasl files for a project 2. I do a require for the project to load and compile 3. I run a query/function and I get the correct "date" data back => #<DATE 01-01-2009> 4. I close emacs and re-open it 5. I do a require of the project to load 6. I run a query/function and I get incorrect "date" data back => 3439756800 Any ideas?
