CCL fails while printing a vector with standard IO syntax

Open galdor opened this issue 2 years ago • 3 comments 

(let ((vector (make-array 0 :element-type '(unsigned-byte 64)
                          :adjustable t :fill-pointer 0)))
  (vector-push-extend 1 vector)
  (vector-push-extend 2 vector)
  (vector-push-extend 3 vector)
  (with-standard-io-syntax
    (print `(make-array ,(length vector)
                        :element-type (unsigned-byte 64)
                        :initial-contents ,vector))))

With SBCL:

(MAKE-ARRAY 3 :ELEMENT-TYPE (UNSIGNED-BYTE 64) :INITIAL-CONTENTS #A((4) (UNSIGNED-BYTE 64) 1 2 3 0))

With CCL 1.12.2:

(MAKE-ARRAY 3 :ELEMENT-TYPE (UNSIGNED-BYTE 64) :INITIAL-CONTEN> Error of type PRINT-NOT-READABLE: Attempt to print object #<VECTOR 4 fill-pointer 3 type (UNSIGNED-BYTE 64), adjustable> on stream #<BASIC-CHARACTER-OUTPUT-STREAM UTF-8 (TTY/1) #x3020004BCB5D> .

The problem is that you're asking to print this vector readably. sbcl uses an implementation specific syntax, so it's de-facto non-conforming code.

Now there may be a question of interpretation of the standard, whether printing readably is limited to same implementation loopbacks, or whether it should be possible across implementations. (Also, whether other *print-...* settings must be taken into account (a strict reading would make us print symbols fully qualified and escaped).

IMO, printing readably notably with standard-io-syntax, should use only standard reader macros syntax. So the bug is in sbcl.

(let ((vector (make-array 0 :element-type '(unsigned-byte 64)
                            :adjustable t :fill-pointer 0)))
  (vector-push-extend 1 vector)
  (vector-push-extend 2 vector)
  (vector-push-extend 3 vector)
  (with-standard-io-syntax
    (let ((*print-readably* nil))
      (print `(make-array ,(length vector)
                          :element-type (unsigned-byte 64)
                          :initial-contents ,vector)))))

(MAKE-ARRAY 3 :ELEMENT-TYPE (UNSIGNED-BYTE 64) :INITIAL-CONTENTS #(1 2 3)) 
(make-array 3 :element-type (unsigned-byte 64) :initial-contents #(1 2 3))
cl-user> #A((4) (UNSIGNED-BYTE 64) 1 2 3 0)

(Note the standard-IO-syntax print in uppercase, and the result printed with *print-case* set to :downcase).

CL Standard 22.1.3.7: "If *print-readably* is true, the vector prints in an implementation-defined manner". WITH-STANDARD-IO-SYNTAX sets *PRINT-READABLY* to T so SBCL isn't non-conformant.

Beyond the fundamental issue of vector printing, I would expect CCL to:

  1. Report precisely the cause of the error.
  2. Print a readable stacktrace instead of dumping a truckload of information that is unexploitable by non-CCL developers (see the multitude of #<error printing object> objects).

Oops, you're right. (I don't like it when the standard allows implementation dependent behavior!)

The error message could be better, I agree.

The backtrace is unlovely, but I assume that the lisp was running in some context where it couldn't enter an interactive break loop.

Issue #253 is about adding an extension to CCL to print arrays readably.

https://github.com/Clozure/ccl/commit/3194ef10ee1fa15ba5e0394974a88ade371e9138 provides a hopefully-better message for print-not-readable.

I guess that the #<error printing object> entries in the backtrace may be due to *print-readably* being bound to true.
