[flexi-streams-devel] flexi-streams 1.0.3 and CMUCL 19e
by Eugene Ossintsev 16 Jul '08

16 Jul '08

Hi, I was trying to compile flexi-streams 1.0.3 with CMUCL 19e and it stopped with the following message in ascii.lisp : -------------------------------------------------------- Type-error in KERNEL::OBJECT-NOT-TYPE-ERROR-HANDLER: 65533 is not of type (UNSIGNED-BYTE 8) [Condition of type TYPE-ERROR] -------------------------------------------------------- As I see, in MAKE-DECODING-TABLE the function MAKE-ARRAY has :element-type 'char-code-integer. And CHAR-CODE-INTEGER is defined as -------------------------------------------------------- (deftype char-code-integer () "The subtype of integers which can be returned by the function CHAR-CODE." '(integer 0 #.(1- char-code-limit))) -------------------------------------------------------- But in CMUCL CHAR-CODE-LIMIT is 256, that is not enough to hold 65533. If I modify mapping.lisp the following way (see also the attached patch): -------------------------------------------------------- (deftype char-code-integer () "The subtype of integers which can be returned by the function CHAR-CODE." - '(integer 0 #.(1- char-code-limit))) + #-:cmu '(integer 0 #.(1- char-code-limit)) + #+:cmu '(integer 0 65533)) -------------------------------------------------------- it's compiled with CMUCL successfully and a simple Hunchentoot web application of mine runs without any problem. But if I try to perform the tests from flexi-streams/test I get a bunch of successful results -------------------------------------------------------- FLEXI-STREAMS-TEST> (run-tests) Test (using COPY-STREAM) "kafka_utf8_lf.txt" (:UTF-8 :EOL-STYLE :LF) [INPUT] --> (:UTF-8 :EOL-STYLE :LF) [OUTPUT]. Test (using COPY-STREAM) "kafka_utf8_lf.txt" (:UTF-8 :EOL-STYLE :LF) [IO] --> (:UTF-8 :EOL-STYLE :LF) [OUTPUT]. Test (using COPY-STREAM) "kafka_utf8_lf.txt" (:UTF-8 :EOL-STYLE :LF) [INPUT] --> (:UTF-8 :EOL-STYLE :LF) [IO]. [[ skipped; too many to put them all here ]] -------------------------------------------------------- followed by some failures (all with the hebrew* files): -------------------------------------------------------- Test (using COPY-STREAM) "hebrew_utf8_lf.txt" (:UTF-8 :EOL-STYLE :LF) [INPUT] --> (:UTF-8 :EOL-STYLE :LF) [OUTPUT].

I know it's far from being perfect. I hope there are much more experienced people here, who know how to fix it. - Eugene

I'm afraid it's about Unicode-non-Unicode characters, > right? Please send but reports to the mailing list (see Cc). I'm not sure what the best thing to do is w.r.t. CMUCL. Should we declare CHAR-CODE-INTEGER to be the same as FIXNUM on CMUCL? Or (integer 0 65535)? Or should at least MAKE-DECODING-TABLE be modified? Opinions? Cheers, Edi. PS: Eugene, as a workaround please try the following in mapping.lisp and report to the list if you still have problems: (defun make-decoding-table (list) "Creates and returns an array which contains the elements in the list LIST and has an element type that's suitable for character codes." (make-array (length list) :element-type 'fixnum :initial-contents list))
