[asdf-devel] circular dependencies
by Seth Burleigh 11 Jun '10

11 Jun '10

Every once in a while when im creating an asd file and it fails to load, when i change it and attempt to load again it signals ASDF could not load script because Condition ASDF:CIRCULAR-DEPENDENCY was signalled.. Now, i know there is no circular dependency, but I cant yet successfully reproduce it consistently, so can someone maybe explain what I should do when that bug occurs so i can track down the source; i.e., how circularity is detected, etc.

[asdf-devel] Question about defsystem
by Robert Goldman 07 Jun '10

07 Jun '10

I was just looking over Scott's bugreports and I am wondering a bit about a snippet in defsystem: (defmacro defsystem (name &body options) (destructuring-bind (&key (pathname nil pathname-arg-p) (class 'system) defsystem-depends-on &allow-other-keys) options (let ((component-options (remove-keys '(:defsystem-depends-on :class) options))) `(progn ;; system must be registered before we parse the body, otherwise ;; we recur when trying to find an existing system of the same name ;; to reuse options (e.g. pathname) from ,@(loop :for system :in defsystem-depends-on :collect `(load-system ,system)) (let ((s (system-registered-p ',name))) *** (cond ((and s (eq (type-of (cdr s)) ',class)) (setf (car s) (get-universal-time))) (s (change-class (cdr s) ',class)) (t (register-system (quote ,name) (make-instance ',class :name ',name)))) (%set-system-source-file (load-pathname) (cdr (system-registered-p ',name)))) (parse-component-form nil (list* :module (coerce-name ',name) :pathname ,(determine-system-pathname pathname pathname-arg-p) ',component-options)))))) Look at the cond that's starred -- the first and third branches both cause the DEFINED-SYSTEMS entry for NAME to be updated to the current value of GET-UNIVERSAL-TIME. But the *second* branch does not seem to (unless it happens by some complex chain as a side-effect of CHANGE-CLASS). Can anyone explain why we shouldn't update the DEFINED-SYSTEMS entry in the case where S already exists but of a different type? Or does this happen as a side-effect of CHANGE-CLASS? Perhaps this is worthy of a comment.... best, r

[asdf-devel] ASDF 2.000 released!
by Faré 31 May '10

31 May '10

Dear Common Lispers, I have finally released ASDF 2, officially starting with release 2.000. http://common-lisp.net/project/asdf/ ASDF 2 is an evolution of ASDF that tries to be backwards compatible with previous releases and their many extensions, while at the same time improving the user experience in many important ways. I have worked hard towards reaching the current state, which I believe is now suitable for release and for inclusion in all Common Lisp implementations. I thank all those who helped develop and test this release, including Robert P. Goldman, James Anderson, Juan-Jose Garcia-Ripoll, and many more. We welcome bug reports on our launchpad site: https://launchpad.net/asdf I'm using ASDF 2 at ITA. Recent versions are already included in ABCL, CCL, CMUCL, ECL. Several hackers have tried building plenty of packages with it. While it's far from my ideal of perfection, and admittedly only a relatively small limited of previous code, I believe it's enough of an advance over the previous generation of ASDF that I'd like to get it out to the world. The code has been extensively cleaned up while preserving previous semantics everywhere that it was well-defined. Our testing has revealed no regressions from ASDF 1. What has changed since ASDF 1 is documented at the following page: http://common-lisp.net/project/asdf/asdf/FAQ.html Improvements include: * portable naming of files wrt directory, type, host/device, etc. * a builtin user-configurable output translation mechanism, superseding asdf-binary-locations and previous hacks in common-lisp-controller and cl-launch. * a user-configurable source registry system for finding systems (the old *central-registry* is still available). * improved portability to many implementations. * improved support for Windows. * many bug fixes * better documentation * the test suite, while still largely incomplete, covers more cases and is more robust across implementations. * substantial performance improvements when processing large systems with thousands of components. * API improvements: load-system, system-relative-pathname, etc. * a sensible versioning system for ASDF 2 itself. * ASDF can be now be upgraded in a running lisp image. Using this in-place upgrade, ASDF releases can be decoupled from implementation releases. * better support for various extensions used by ECL and ABCL, and also by POIU, ASDF-DEPENDENCY-GROVEL. Pitfalls include: * Output translations is enabled by default. This may surprise some users, most of them in pleasant way (we hope), a few of them in an unpleasant way. It is trivial to disable output translations. Simply put (ASDF:DISABLE-OUTPUT-TRANSLATIONS) in a Lisp startup file. * Some systems in the large have been known not to play well with asdf output translations. They were easy to fix. The most likely issue is to have chaining of operations (e.g., a preprocessing before a load) where the INPUT-FILES of one operation are related to the OUTPUT-FILES of another. In this case many issues can be avoided by simply making the OUTPUT-FILES primary, and having later operations' INPUT-FILES be defined in terms of the OUTPUT-FILES of other operations instead of directly defining the INPUT-FILES. It is also easy to disable output translations or override its configuration. * ASDF 2 output translations do not work with ASDF-Binary-Locations. They replace A-B-L, and include a compatibility mode to emulate your previous A-B-L configuration. See ENABLE-ASDF-BINARY-LOCATIONS-COMPATIBILITY. But you shouldn't load ABL on top of ASDF 2. * A notable performance bug on SBCL (and possibly other implementations, too): the recursive search of configured paths in your source-registry with (DIRECTORY "/configured/path/**/*.asd") can waste a few seconds when initially searching for asd files (depending on your configuration). If it is essential for you to avoid this pause, you should override the default source-registry and only use non-recursive :DIRECTORY options (or shallow trees). Or just keep the default directory hierarchies being searched empty. * Windows support may have been insufficiently well tested. As to how to best include ASDF in your implementation, here is an excerpt from the FAQ section of our manual: 12.3.2 "I'm a Common Lisp implementation vendor. When and how should I upgrade ASDF?" Starting with current candidate releases of ASDF 2, it should always be a good time to upgrade to a recent version of ASDF. You may consult with the maintainer for which specific version they recommend, but the latest RELEASE should be correct. We trust you to thoroughly test it with your implementation before you release it. If there are any issues with the current release, it's a bug that you should report upstream and that we will fix ASAP. In order to report bugs, please use the launchpad bug tracker. Information about launchpad is contained in the manual. As to how to include ASDF, we recommend the following: * If ASDF isn't installed yet, then (require :asdf) should load the version of ASDF that is bundled with your system. You may have it load some other version configured by the user, if you allow such configuration. * If your system provides a mechanism to hook into CL:REQUIRE, then it would be nice to add ASDF to this hook the same way that SBCL, ECL, CMUCL, CCL and ABCL do. * You may, like SBCL, have ASDF be implicitly used to require systems that are bundled with your Lisp distribution. If you do have a few magic systems that come with your implementation in a precompiled way such that one should only use the binary version that goes with your distribution, like SBCL does, then you should add them in the beginning of wrapping-source-registry. Please consult with the ASDF maintainers about that. * If you have magic systems as above, then we explicitly ask you to NOT distribute asdf.asd as part of those magic systems. You should still include the file asdf.lisp in your source distribution and precompile it in your binary distribution, but asdf.asd if included at all, should be secluded from the magic systems, in a separate file hierarchy, or you may otherwise rename the system and its file to e.g. asdf-ecl and asdf-ecl.asd, or sb-asdf and sb-asdf.asd. If you make asdf.asd a magic system, then users will no longer be able to upgrade ASDF using ASDF itself. It is helpful to be able to do this in order for users to be able to use an ASDF version of their own choosing that they maintain independently from your Lisp distribution. * If you do not have any such magic systems, or have other non-magic systems that you want to bundle with your implementation, then you may add them to the default-source-registry, and you are welcome to include asdf.asd amongst them. * Please send us upstream any patches you make to ASDF itself, so we can merge them back in for the benefit of your users when they upgrade to the upstream version.

[asdf-devel] question about relative pathname to point to parent directory
by Robert Goldman 26 May '10

26 May '10

What's the right syntax for specifying a relative pathname for a module whose files should live in the parent directory instead of in a subdirectory? E.g., if I have (:module foo :components ((:file "bar") (:file "baz")) :pathname ???? ) what goes in there if I do NOT want the files to live in foo/, but with all the other files? I could put a FAQ about this in the manual... best, r

[asdf-devel] Question about pathnames discussion in the manual
by Robert Goldman 26 May '10

26 May '10

Currently, the manual's discussion about logical pathnames states: "Moreover, the `asdf-output-translation' layer will avoid trying to resolve and translate logical-pathnames, so you can define yourself what translations you want to use with the logical pathname facility." IIUC, since a-o-t does not handle logical pathnames, it's not so much that you /can/ define the translations you want to use with the l-p facility as that you /must/ define the translations, or your binaries will go untranslated. Do I understand this correctly? If so, any objection to my strengthening the wording here? I am making some minor tweaks to this section, which I was just in because I was on irc the other day helping Stellian and Raymond with some pathname issues in ASDF 2 compatibility. Best, r

[asdf-devel] Planning to release ASDF 2 next monday
by Faré 25 May '10

25 May '10

I found and fixed a bug last Friday, which is why I didn't release yet. If no new bug is found, I'd like to release ASDF 2 next monday. In the meantime, can you all test the latest ASDF (current: 1.728) with your favorite Lisp implementation, packages, etc. ?

[asdf-devel] ASDF2: Bug in merge-pathnames*
by Jean-Claude Beaudoin 19 May '10

19 May '10

Here is a patch against 1.720 that fixes a weakness in merge-pathnames*. This was a show stopper in my system. It seems that merge-pathnames* assumes that *default-pathname-defaults* has some interesting value to contribute which is not always the case. In my system and in a few others (clisp comes to mind) the usual value of *default-pathname-defaults* is #P"" which ends up giving (pathname-directory *default-pathname-defaults*) => nil Then, (append nil (cdr directory)) is probably not a "valid pathname directory". In clisp passing this not so "valid pathname directory" to make-pathname will result in a visit in the debugger... I want also to insist again on the issue of accessing the process current directory. Assuming that *default-pathname-defaults* is a substitute for the process current directory is not portable ANSI Common Lisp code. The following definition is very likely to be wrong on at least one ANSI Common Lisp conforming implementation: (defun current-directory () (truenamize (pathname-directory-pathname *default-pathname-defaults*))) Cheers, Jean-Claude Beaudoin ------- > diff asdf-1.720/asdf.lisp asdf.lisp 519c520,522 < (append (pathname-directory defaults) (cdr directory)) --- > (if (pathname-directory defaults) > (append (pathname-directory defaults) (cdr directory)) > directory)

[asdf-devel] :exclude in source-registry.conf getting ignored.
by szergling 16 May '10

16 May '10

Hi list, Is it intended that :exclude in ~/.config/common-lisp/source-registry.conf should come before the :tree directive(s)[1]? To me, the manual seems to specify that the order in which the directives are provided does not matter. I'm using asdf version "1.720". To set the context, and perhaps as another question, I was originally investigating if it was possible to exclude a specific tree (sure, matching a pattern works and is good enough) or directory, or have some other way to suppress the loading of duplicated systems (usually repo branches). Yong. [1] Compare: With this in the user config file, (:source-registry (:exclude "asdf-exclude") (:tree "/home/tyc20/lisp/") :ignore-inherited-configuration) > (flatten-source-registry) ==>((#P"/home/tyc20/lisp/imp/sbcl-1.0.29-x86-linux/install/lib/sbcl/" :RECURSE T :EXCLUDE (".bzr" ".cdv" "~.dep" "~.dot" "~.nib" "~.plst" ".git" ".hg" ".pc" ".svn" "CVS" "RCS" "SCCS" "_darcs" "_sgbak" "autom4te.cache" "cover_db" "_build")) (#P"/home/tyc20/lisp/" :RECURSE T :EXCLUDE ("asdf-exclude"))) With this in the config file instead: (:source-registry (:tree "/home/tyc20/lisp/") (:exclude "asdf-exclude") :ignore-inherited-configuration) > (flatten-source-registry) ==>((#P"/home/tyc20/lisp/imp/sbcl-1.0.29-x86-linux/install/lib/sbcl/" :RECURSE T :EXCLUDE (".bzr" ".cdv" "~.dep" "~.dot" "~.nib" "~.plst" ".git" ".hg" ".pc" ".svn" "CVS" "RCS" "SCCS" "_darcs" "_sgbak" "autom4te.cache" "cover_db" "_build")) (#P"/home/tyc20/lisp/" :RECURSE T :EXCLUDE (".bzr" ".cdv" "~.dep" "~.dot" "~.nib" "~.plst" ".git" ".hg" ".pc" ".svn" "CVS" "RCS" "SCCS" "_darcs" "_sgbak" "autom4te.cache" "cover_db" "_build")))

[asdf-devel] 1.721
by Faré 11 May '10

11 May '10

I made an incompatible change in 1.721: before that, it was a *convention* that configuration files in configuration directories :include'd by the source-registry or the output-translations configuration should have :type "conf". This interacted poorly with backup files stored in same directory by default by various editors. There was also the confusing issue that "*.*" would match anything on some implementations (e.g. SBCL) but only files with a . in their name in others (e.g. CLISP). So I made the convention something enforced and this should change the problem, at the cost of backwards incompatibility with whoever started using that feature while defying the convention. Otherwise, I've made a few changes based on feedback from various people, whom I thank. I also strongly disrecommend releases 1.714 to 1.718 that have a bug in an incomplete cleanup that prevent them from loading some systems that use symbols to name components, such as fiveam and many more. My apologies for the change. The same cleanup seems to have broken ASDF-INSTALL (one line change needed, oops), and anyone who previously defined methods on the internal function find-component (in retrospect, I should have changed the name of the function.)

[asdf-devel] Fwd: Re: [Openmcl-devel] asdf 2 imported into trunk

This was in the openmcl-devel list. Question: should we bundle a version of ASDF-INSTALL that's known to be compatible?

If you find a bug, > please report it at https://launchpad.net/asdf or use the asdf > mailing list: http://common-lisp.net/cgi-bin/mailman/listinfo/asdf-devel FWIW, I ran into an issue with the new version of asdf (i.e., asdf 2) and the latest asdf-install. There's a simple, one line fix to the most recent asdf-install to make it work with the asdf 2. In the file installer.lisp which is part of asdf-install, an around method for the generic function find-component has an incompatible lambda list. The latest version of installer.lisp from asdf-install has this: (defmethod asdf:find-component :around ((module (eql nil)) name &optional version) (declare (ignore version)) ... just remove the &optional parameter and the subsequent declaration: (defmethod asdf:find-component :around ((module (eql nil)) name) ... and now asdf-install will load and work properly. (well, it still doesn't pass its own test suite because it tries to use an illegal character in a filename when writing its report, but it does successfully install asdf-installable systems). warmest regards, Ralph Raffael Cavallaro raffaelcavallaro(a)me.com _______________________________________________ Openmcl-devel mailing list Openmcl-devel(a)clozure.com http://clozure.com/mailman/listinfo/openmcl-devel
