[asdf-devel] broken texinfo link
by nuntius＠strider2.example.org 20 Nov '09

20 Nov '09

asdf.texinfo still refers to Kent's old site at http://world.std.com/~pitman/Papers/Large-Systems.html It should be updated to http://nhplace.com/kent/Papers/Large-Systems.html - Daniel

[asdf-devel] update defsystem grammar for method forms
by Robert P. Goldman 20 Nov '09

20 Nov '09

I was trying to write some in-line method definitions in defsystem and found that the system grammar supplied in the manual did not specify the grammar for this. The grammar is actually a little tricky, and doesn't support specifying primary methods, so I think an extension to the docs is warranted. Best, r

Nuntius provided a patch for an out-of-date pointer to Kent Pitman's paper in asdf.texinfo. Here's a patch for that.

[asdf-devel] First steps for ECL support
by Juan Jose Garcia-Ripoll 17 Nov '09

17 Nov '09

I have split the change into two, as I normally do in the ECL source tree itself. The first change only pertains asdf.lisp and it adds a slot, FLAGS, to COMPILE-OP. These are additional flags for COMPILE-FILE. It is used by ECL because we want to produce two files per source file: an object file and the FASL itself. These files can be separately used for building larger things (shared libraries, programs...) or for immediate loading. The second set of changes is isolated in a single file, asdf-ecl.lisp, which is more complex. This file contains a number of extensions, which may or may not be adapted to other platforms (I believe it is possible, at least for some things). What it implements: - COMPILED-FILE, a new component for distribution of pre-compiled files. I use it to build pre-packaged versions of RT, the compiler and other things that now can be included as dependencies. - A number of operations for creating shared libraries, programs, etc. These operations use traverse in a funny way to find out the order in which files should be combined. I call them BUNDLEs because the result is a single binary file that combines many lisp sources, compiled. It has an important advantage for ECL, apart from distribution, for it takes less resources to load a single file. - A function, MAKE-BUILD, which uses those operations hiding the details. - A new operation, LOAD-FASL-OP, which uses those "bundles". - A hook into REQUIRE using LOAD-FASL-OP. What is implemented more or less follows this http://ecls.sourceforge.net/new-manual/ch16.html Comments are welcome.

[asdf-devel] Two questions
by Nick Levine 17 Nov '09

17 Nov '09

1. Problems with the :feature feature. (asdf:defsystem foo :components ((:file "pkg") (:file "code") (:file "foo" :depends-on ((:feature :frob))))) If :frob is not on *features*, load-system gives me: Error: Bad dependency (FEATURE FROB). Dependencies must be (:version <version>), (:feature <feature>), or a name If :frob is a *feature* I get a different error: Error: Error component :FROB not found, required by #<CL-SOURCE-FILE "foo" #x8B7A3E6> Did I misunderstand something? 2. Suppose I would like some code to run at compile-time / load-time to determine where the fasls should live (e.g. hypothetically, in a subdirectory named after a timestamp, or according to what patches I have loaded). How do I express this? (I'm using version 1.363) Thanks. - nick

[asdf-devel] performance of find-system (on sbcl)

dear list, find-system is so slow that i took the time to look into it. this is what i've used to test: (sb-sprof:with-profiling () (trace sb-fasl::load-as-source) (time (labels ((recurse (system-name) (let ((system (asdf:find-system system-name nil))) (dolist (child (rest (first (asdf:component-depends-on 'asdf:compile-op system)))) (recurse (asdf:find-system child nil)))))) (recurse (asdf:find-system :hu.dwim.walker nil))))) out of the box run: Evaluation took: 3.233 seconds of real time 2.350000 seconds of total run time (2.120000 user, 0.230000 system) [ Run times consist of 0.410 seconds GC time, and 1.940 seconds non-GC time. ] 72.69% CPU 15,573 forms interpreted 2,688 lambdas converted 5,615,673,160 processor cycles 15 page faults 128,748,160 bytes consed when adding the following to asdf:find-system, just around the cl:load call: #+sbcl (sb-ext:*evaluator-mode* :interpret) Evaluation took: 1.506 seconds of real time 0.740000 seconds of total run time (0.640000 user, 0.100000 system) [ Run times consist of 0.110 seconds GC time, and 0.630 seconds non-GC time. ] 49.14% CPU 16,582 forms interpreted 56 lambdas converted 2,764,841,332 processor cycles 2 page faults 58,959,808 bytes consed any thoughts on this? -- attila

[asdf-devel] problems defining a new component class
by Robert Goldman 13 Nov '09

13 Nov '09

I'm finding that for some reason the :default-initargs to a new component class (a subclass of cl-source-file) I've defined are not getting applied. I have a vague memory that there's some weirdness in the way asdf creates components that means that this doesn't work, but I'd be obliged if anyone could provide more guidance. In particular, I would be very grateful for any suggested workaround if, as I suspect, this is something that ASDF simply won't let me do. many thanks, r

[asdf-devel] ASDF improvements from ECL

(Moving the discussion from the ecl list to the asdf list, originally Re: ECL support for cl-launch and xcvb) 2009/11/9 Juan Jose Garcia-Ripoll <juanjose.garciaripoll(a)googlemail.com>: >> For the record, the issue I finally found and fixed in building an >> image was as follows: asdf:traverse is traversing system dependencies > > I have a problem with asdf:traverse.

I propose you offer a patch, and convince people with lots of systems to try it. I'm volunteering to try your backwards-incompatible ASDF improvements on all the systems used at ITA. Possibly, the DWIM.hu guys will try it on all the systems they have, and so on. If no one complains (and why should they?) then your patch will be a strong candidate for inclusion.

Yes, I saw the patch, but couldn't assume the authority to (in)validate it, and probably no one else could. Getting a patch widely tested could reassure us that "in practice, no one relies on the behavior of the old TRAVERSE where it is incompatibly redefined by the new one".

[asdf-devel] Recompile if dependent system changed
by Tobias C. Rittweiler 09 Nov '09

09 Nov '09

As far as I'm told (and that matches my experience), ASDF does not recompile the current system if a dependent system changed, unless of course :FORCE T is specified. This is logged as https://bugs.launchpad.net/asdf/+bug/479522 -T.
