[armedbear-devel] Bug in metaclass support
by Alessio Stalla 11 Apr '10

11 Apr '10

Hello, this piece of code produces an error: (defclass foo () () (:METACLASS STANDARD-CLASS) (:DOCUMENTATION "bar")) condition of type PROGRAM-ERROR: Invalid initarg :DOCUMENTATION while it works perfectly fine without :metaclass, presumably because make-instance is not called to create the class metaobject. On class redefinition (say, I define foo without :documentation, and redefine it with it), it gives no error. This breaks Cells which always puts in a :metaclass option even when superfluous. Bye, Alessio

[armedbear-devel] Ticket #88: Predicate to distinguish Java-based and lisp-compiled functions
by Erik Huelsmann 10 Apr '10

10 Apr '10

Regarding ticket 88, I have the following idea: Lisp functions inherit from either Primitive or CompiledClosure. CompiledClosure isn't used elsewhere, but Primitive is used everywhere in Java too. How about creating an (empty) CompiledPrimitive which isn't used Java-side. Then, with a simple 'instanceof' test, functions can be tested to have been compiled from Lisp or created from Java. How about that? Bye, Erik.

[armedbear-devel] Low memory condition signalling
by Erik Huelsmann 09 Apr '10

09 Apr '10

Hi, Yesterday I completed an abcl-dev blogpost about 0.18 which handles out of memory (OOM) conditions much better than earlier versions. However, as the post concludes, it would be even lispier to have a low-memory signal instead of OOM, because in that case the condition system can be used to handle the situation right in the call stack where the condition occurred, in order to be able to continue execution after handling the condition. Douglas Miles suggested we use JMX memory management notifications to create this behaviour. Before we can implement such behaviour, a number of questions need to be answered: * How does an application tell the difference between our current OOM condition and the new behaviour? -> this is important, because the current behaviour unwinds the stack; the future one won't * Do we remove the current behaviour? * Do we let the user select the parameters for signalling the requested condition? * Should we let the user install handlers to be called when a condition like this occurs? * <others>? Regards, Erik.

[armedbear-devel] Unicode support vs spec conformance
by Erik Huelsmann 05 Apr '10

05 Apr '10

This started with Douglas Miles remarking that 2 tests in the ansi test suite have been failing ever since we increased CHAR-CODE-LIMIT to #x10000.That change was associated with our intended support for Unicode. As it turns out, Unicode has defined characters which conflict with a requirement from the CLHS: CLHS requires that characters be defined in exact pairs, if they have 'case'. This means that the functions char-upcase and char-downcase can be used to retrieve the character's "other case" equivalent. However, in Unicode there are characters which don't have that property: for example LATIN SMALL LETTER DOTLESS I maps to the LATIN CAPITAL LETTER I, just as the LATIN SMALL LETTER I. Obviously, the capital can't map back to both. See here the issue with CLHS compliance emerge. Three possible solutions have come up: 1a. Be CLHS compliant, but not Unicode 1b. Same as (1a), but provide specific Unicode up/down casing functions 2. Be Unicode compliant and not CLHS. SBCL (and from Sam Steingold's remark CLISP too) chooses 1a: I haven't found a function to do Unicode up/down casing; it defines the uppercase of the dotless i to be itself (caseless). This solution results in CLHS compliance, but in my opinion, isn't the solution with the least surprise: if you decide you want to upcase a string - without in-depth awareness of the issue - you're suddenly faced with a string which is upcased, except for a number of characters. I would propose we - documentedly - diverge from the CLHS on this issue: we follow Unicode and the upper case version of the dotless i is just the capital i. From a user perspective, this seems like the solution of least surprise: I would expect people who use characters which can't be round-tripped to understand about that. Sam suggests there's an issue with symbol i/o. He's probably referring to *readtable-case* and *print-case*. My reasoning here too is that people using characters like these in their symbols would expect to be familiar with both the casing behaviour of the Common Lisp reader/printer and the behaviour of their letters in such circumstances: if a string were uppercased in a certain way, wouldn't it be extremely weird if your symbols wouldn't too - given that your Common Lisp claims Unicode support? So, my proposal here is to diverge. What are your opinions? Bye, Erik.

[armedbear-devel] Where is ASDF2?

git clone http://common-lisp.net/project/asdf/asdf.git seems to have the latest ASDF 1. I can't seem to find ASDF 2. A pointer would be appreciated. Thanks. Blake McBride

[armedbear-devel] Understanding Unicode support
by Erik Huelsmann 04 Apr '10

04 Apr '10

Hi all, In an effort to make our Unicode support comprehensible, I've started a wiki page to document what's all to be considered. The page is at http://trac.common-lisp.net/armedbear/wiki/CharsetSupport Please contribute directly to the page or send your amendments here for inclusion. Bye, Erik.

[armedbear-devel] Unicode, CHAR-UPCASE/CHAR-DOWNCASE and char-upcase.1/char-upcase.2
by Erik Huelsmann 04 Apr '10

04 Apr '10

Ever since ABCL raised its CHAR-CODE-LIMIT from 256 to #x10000, 2 tests started failing: char-upcase.1 and char-upcase.2. These 2 tests iterate through all integers between 0 and CHAR-CODE-LIMIT. While doing so, they test for the property that upcasing and downcasing returns the same character again ("round-tripping"). This property of characters is specified in section 13.1.4.3 (http://www.lispworks.com/documentation/lw51/CLHS/Body/13_adc.htm) "Characters with case". In short: characters with case are defined in pairs; additional characters with case have to be defined in pairs too. The spec provides char-upcase and char-downcase to convert characters-with-case to their 'other-case equivalent'. However, in section 13.1.10, there seems to be an escape hatch: "Documentation of implementation-defined scripts". A script is a subtype of CHARACTER, nothing more nothing less. An implementation-defined script gets to document the effect on CHAR-UPCASE and CHAR-DOWNCASE. Now, if I were to define our Unicode script to be every character except those in the base set, char-upcase and char-downcase may have different semantics, except for the standard characters. That way, there's no need to have the round-tripping requirement apply to most of unicode - as can't be expected, see latin-small-letter-dotless-i for an example. In the light above, is it really portable for the tests to assume all characters must be round-tripped? I think it's not. What are your opinions? Bye, Erik.

[armedbear-devel] Loading from jar - status
by Reinhard Oldenburg 03 Apr '10

03 Apr '10

Dear ABCL-Team, some time a go the theme of loading compiled files from jar-archives has been discussed on this list but somehow I missed the final conclusion. There seems to be no example or documentaion of this feature. Especially I'm interested in loading Maxima from a jar file - is this possible? Yours, Reinhard Oldenburg

[armedbear-devel] lisp interpreter inside a beanshell JConsole?
by Alan Ruttenberg 03 Apr '10

03 Apr '10

Hi, I'm trying to set up a lisp shell inside protege, by copy pasting from the bean shell example they have: http://code.google.com/p/co-ode-owl-plugins/source/browse/trunk/org.coode.s… (see http://www.beanshell.org/manual/jconsole.html) Unfortunately I'm losing, with the first eval I call resulting in a null pointer exception. I expect I don't know how to set up the top level loop to run with the JConsole streams. Can anyone help? Thanks, Alan
