[cl-prevalence-devel] Patch for serializing improper lists
by Henrik Hjelte 31 Jan '06

31 Jan '06

I have made some changes in s-serialization that allows improper-lists, for example cons-pairs and circular lists. They used to fail with a type-error. I have made the changes inside the method for sequences rather than an another method specialised on lists. That way a proper list is output as a sequence (which is prettier), and an improper list is output as a list of cons-pairs. Circular lists are handled by first making a fresh cons in the hash-table of deserialized objects, and then replacing its cdr with a reference to the first cons in the circular list, which is also stored in the hash-table. Some new simple tests have also been added. The source files are attached, and a diff against the latest version in CVS. I have only tested this on x86 SBCL, but it should work on all implementations. Best wishes, Henrik Hjelte

[cl-prevalence-devel] S-SYSDEPS
by Sven Van Caekenberghe 09 Jan '06

09 Jan '06

From now on, the local sydeps.lisp file is replace by a dependency on the more general S-SYSDEPS package ( http://homepage.mac.com/svc/s- sysdeps/ ). Only in CVS HEAD for now, if there are no objections, I will release this soon to the tarballs. Sven

Marko, Thx for reporting this problem. I 'fixed' it by no longer loading debug-prevalence by default. The s-xml::echo-xml function (used here for pretty printing xml) is no longer loaded by default. Compilation/loading using LispWorks and SBCL is now OK.

[cl-prevalence-devel] cl-prevalence on clisp
by Tomas Zellerin 05 May '05

05 May '05

Hello, I tried yesterday to run cl-prevalence on recent clisp. I found that following does not work: - serialization of classes, the reason being that serializable-slots for standard objects has no #+clisp section. I was able to overcome this particular problem, can make and send patch, if clisp is also considered as target for this package - serialization of pathnames. I could make plausibly looking serialization code, but did not get how to handle de-serialization. Is the latter problem of clisp only? Is it supposed to work? With regards, Tomas Zellerin

Attached to this message is a patch for serialization.lisp which makes it work on SBCL. The only difference from the CMUCL-specific MOP code is that SBCL has, for some reason, renamed the PCL package to SB-PCL. For your inspection (and in case attachments don't play well with this mailing list): --- serialization.lisp.old 2005-01-20 13:17:35.000000000 -0700 +++ serialization.lisp 2005-01-20 13:12:52.000000000 -0700 @@ -112,6 +112,8 @@ (mapcar #'car (if (symbolp (caar slots)) slots (cdr slots)))) #+cmu (mapcar #'pcl:slot-definition-name (pcl:class-slots (class-of object))) + #+sbcl + (mapcar #'sb-pcl:slot-definition-name (sb-pcl:class-slots (class-of object))) #+lispworks (structure:structure-class-slot-names (class-of object)) #+allegro @@ -125,6 +127,8 @@ (class-of object))) #+cmu (mapcar #'pcl:slot-definition-name (pcl:class-slots (class-of object))) + #+sbcl + (mapcar #'sb-pcl:slot-definition-name (sb-pcl:class-slots (class-of object))) #+lispworks (mapcar #'hcl:slot-definition-name (hcl:class-slots (class-of object))) #+allegro -Peter

James, Thanks for the feedback. Here is a first reaction, without looking at your code. On 27 Nov 2004, at 03:58, James Wright wrote: > The first bug is pretty minor: An attempt to serialize a > standard-object will fail if any of its slots are unbound. This is probably fixed in the CVS version (among other things) - have a look at the mailing list(s). > The second bug is somewhat mystifying.

I'm using Lispworks > with a stack size of 64000. I never tried chains that long. But yes there might be a problem here: the serializer tracks every object it encounters, and is itself a recursive process. Although 1300 doesn't seem that large a number. I am using LW myself, and sometimes you have to expand the stack a couple of times for very recursive code to succeed. I will have a look at your example later on. Sven
