[cmucl] #85: Hemlock fails to start

#85: Hemlock fails to start ---------------------+------------------------------------------------------ Reporter: rtoy | Owner: rtoy Type: defect | Status: new Priority: minor | Milestone: Component: Hemlock | Version: 2013-06 Keywords: | ---------------------+------------------------------------------------------ On some systems, {{{ (require :hemlock) (ed) }}} causes an X error. This is due to the fact that Hemlock wants to use Courier fonts which are not available on the system. The workaround is to install Courier fonts on the system. -- Ticket URL: <http://trac.common-lisp.net/cmucl/ticket/85> cmucl <http://common-lisp.net/project/cmucl> Cmucl is a high-performance, free Common Lisp implementation.

#84: motifd is a 64-bit app --------------------+------------------------------------------------------- Reporter: rtoy | Owner: rtoy Type: defect | Status: new Priority: minor | Milestone: Component: CLM | Version: 2013-06 Keywords: | --------------------+------------------------------------------------------- {{{motifd}}} is a 64-bit application, unlike {{{lisp}}} which is a 32-bit app. This is only a problem if you install on a 32-bit OS where {{{motifd}}} won't run at all. But making {{{motifd}}} a 32-bit app may cause problems on a 64-bit OS where the necessary 32-bit X libraries are not installed. In addition, I (rtoy) have difficulties building {{{motifd}}} as a 32-bit app on linux. -- Ticket URL: <http://trac.common-lisp.net/cmucl/ticket/84> cmucl <http://common-lisp.net/project/cmucl> Cmucl is a high-performance, free Common Lisp implementation.

#82: Source location error on large files --------------------+------------------------------------------------------- Reporter: rtoy | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: Core | Version: 2013-05 Keywords: | --------------------+------------------------------------------------------- As noted in the [http://article.gmane.org/gmane.lisp.cmucl.general/6497 email from Matt Kaufmann], there is an error in computing the source location. The problem was that the file was very large with many long forms. This caused the form number to overflow the 14-bit number used to hold the form number. -- Ticket URL: <http://trac.common-lisp.net/cmucl/ticket/82> cmucl <http://common-lisp.net/project/cmucl> Cmucl is a high-performance, free Common Lisp implementation.

#81: Reversing a string is slow --------------------+------------------------------------------------------- Reporter: rtoy | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: Core | Version: 2013-05 Keywords: | --------------------+------------------------------------------------------- Consider this: {{{ (defparameter *s* (make-string 1000000)) (defun time-rev (s) (dotimes (k 100 nil) (declare (fixnum k)) (setf s (reverse s))) s) (compile 'time-rev) (time (prog1 t (time-rev *s*))) ; Evaluation took: ; 10.23 seconds of real time ; 10.151641 seconds of user run time ; 0.079628 seconds of system run time ; 31,310,669,055 CPU cycles ; [Run times include 0.08 seconds GC run time] ; 0 page faults and ; 200,114,224 bytes consed. }}} Since strings are basically arrays of unsigned 16-bit integers, compare the time when reversing an array: {{{ (defparameter *v* (make-array 1000000 :element-type '(unsigned-byte 16))) (time (prog1 t (time-rev *v*))) ; Evaluation took: ; 3.62 seconds of real time ; 3.581727 seconds of user run time ; 0.039302 seconds of system run time ; 11,089,005,122 CPU cycles ; [Run times include 0.05 seconds GC run time] ; 0 page faults and ; 200,116,120 bytes consed. }}} Reversing a string is 3 times slower.

#79: File-position at start of file is wrong --------------------+------------------------------------------------------- Reporter: rtoy | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: Core | Version: 2013-03-a Keywords: | --------------------+------------------------------------------------------- Let {{{foo}}} be an file of latin1 characters. Then {{{ (with-open-file (s "foo" :external-format :latin1) (print (file-position s)) (read-char s) (print (file-position s))) }}} prints {{{ 512 513 }}} This is totally unexpected.

If {{{foo}}} has utf8 encoding then {{{ (with-open-file (s "foo" :external-format :utf8) (print (file-position s)) (read-char s) (print (file-position s))) }}} prints something like {{{ 512 1 }}} I would expect 0 to be printed instead of 512. -- Ticket URL: <http://trac.common-lisp.net/cmucl/ticket/79> cmucl <http://common-lisp.net/project/cmucl> Cmucl is a high-performance, free Common Lisp implementation.
