2. There is some undiagnosed problem in translating the binary location for the new ASDF2 "~/.cache" conventions, as ABCL seems to "collapses" everything into a single directory. Somehow, the default *output-translations* have a "/**/**/*.*" where there should be "/**/*.*". I'm not sure if this is a problem in "abcl-translate-pathname.patch", which is why I didn't apply this to ABCL trunk.
3. ASDF's run-tests.sh seems to ignore the "flags" setting, which seems to be broken on the ASDF side.
4. The changes for ASDF look quite interesting. However I would advocate that you should make ASDF2 work *exactly* like ASDF1 out of the box, meaning you shouldn't do any of the subsumed ASDF-BINARY-LOCATIONS stuff without being asked to by configuration.
How do you feel about integrating asdf-binary-locations into ABCL as well. I would make one change to what's there now, which is to add :java-1.4, :java-1.5, :java-1.6 to the list of architectures it has.

The new ASDF (aka ASDF2) comes with its own version of ASDF-BINARY-LOCATIONS, which it supercedes. So, if we can integrate ASDF2—which I intend to do—we'll have binary locations. They're a little different than previous behavior, but immensely more configurable, so I assume you can get them to emulate the current implementation that you are using.

Excellent. Let me know when to try.

Alan,
ASDF-Binary-Locations has been obsoleted and replaced by the more easily configurable ASDF-Output-Translations, which is now built into ASDF itself.
ASDF 1.660 also includes some compatibility mode with ABL, if for some reason you love the old ABL way.
I hope ABCL has fixed its merge-pathnames woes.

Right: we still include ASDF 1.3 with ABCL.
I'm looking at upgrading ABCL trunk to the new (aka ASDF2) version, but right now ASDF2 cannot load systems from jar files so I haven't put it on trunk just yet.
One can load ASDF2 from ASDF quite easily, for those wishing to experiment along with me.

Can ASDF1 do this loading from jar files? I certainly didn't remove anything from it. If you have a local patch to ASDF1 to do it, I'll be please to include it in either ASDF2 or a contrib to it.
If there are any regressions from ASDF1 to ASDF2, I want them fixed. Otherwise, there shouldn't be a problem upgrading ABCL from ASDF1 to ASDF2.

Yes, ABCL ADSF1 can load from jar files and no, nothing has been removed from ASDF2 as it's more of a case of what has been added, namely that it now OPENs the .asd file instead of LOADing it, and ASDF-BINARY-LOCATIONS are baked-in.
That a Pathname for jar locations in ABCL are not currently capable of being OPENed turns out to be easily implemented (see attached patch).
That a jar Pathname is not a writable location turns out to cause problems for the binary locations part of ASDF2. It was sufficient to [patch the behavior][1] of ASDF1 to have OPERATION-DONE-P return T if all the members of the output files of COMPILE-OP on a CL-SOURCE-FILE were determined to be within a jar. But this turns out only to have worked with ABCL because there was a bug in how *LOAD-TRUENAME* was computed in loading from a jar Pathname that I would like to fix going forward (it's fixed in the patch).
[1]: http://trac.common-lisp.net/armedbear/browser/trunk/abcl/src/org/armedbear/l...
It would be perhaps cleaner to have the binary locations machinery of ASDF2 react to not being able to write to the Pathname derived from the location of the ".asd" file in an extensible manner. This might be useful for users of Lisps other than ABCL who don't have permission to write to the system ASDF location for instance. My current problem is that the :BEFORE for PERFORM specialized on COMPILE-OP SOURCE-FILE contains an ENSURE-DIRECTORIES-EXIST which by default is derived from the ".asd" Pathname. Is there a way to per-system customization of the output location?
Thinking quickly for an ASDF2 algorithm:
1. Is the directory containing the ".asd" writable? If so, continue normally.
2. Otherwise, can we establish an alternative location to write the output of COMPILE-OP as configured by the user? If so, continue normally.
3. Otherwise, skip the COMPILE-OP of this system. For LOAD-OP, search for FASLs by some user-extensible mechanism, falling back to looking in the same directory as the ".lisp" files. If no FASLs can be found, load the source files.
If there are any regressions from ASDF1 to ASDF2, I want them fixed. Otherwise, there shouldn't be a problem upgrading ABCL from ASDF1 to ASDF2.
No regressions have been noted; I will report them if found. As it stands, I can't upgrade ABCL to ASDF2 without breaking the existing functionality of loading ADSF definitions from jars. The responsibility for fixing this situation certainly lies with ABCL's extension of Pathnames to cover jar files, which we are working to bring in line with new features offered by ASDF2.
Dear Mark,

OK. But doesn't asdf-output-translations (the replacement for asdf-binary-locations) by default redirect the output to a user cache? Or did you disable that?
Do you want me to merge that into upstream ASDF with #+abcl conditions?
Note: If ABCL supports matching and translating such paths, there could be ASDF-Output-Translation rules by default with ABCL in the idea of (#p"/**/*.jar/**/*.*" (:home #p"**/*.jar/**/*.*")

Juanjo of ECL was thinking of a different delivery mechanism, where compiling a ASDF system would yield another ASDF system of the same interchangeable name, but the content of which would be just one or several binary objects to load.
Perhaps that's what you really want to be using?

Not sure, which is why I was floating the idea for comments, but if I can run a user-defined function after the .asd has been parsed to programatically implement the following, that might work. I need to read up on what is present in the currently defined mechanism.

Faré would it be possible/appropriate to take the core of find-system which does the work of loading the system (opening the file, interpreting it, etc.), and package it up as a generic function so that it would be possible for customizers to add :before, :after, and :around methods?

I've now spent some time understanding the output translations method in ASDF2, and think ABCL would be best served if we could add the ability to specify an arbitrary function as an output translation "destination". The extensions that Robert suggests would be interesting, but I don't have a current use case for them in application to ABCL.
Fare's suggestion that I use an output translation based on the jar pathname doesn't quite work, because in our current implementation, the pathname of the jar is stored in DEVICE, separate from the rest of the jar pathname. I extended PATHNAME-MATCH-P to match jars correctly, but I don't see a possible extension of TRANSLATE-PATHNAME. For purposes of discussion consider that a jar pathname has a namestring composed of "jar:file:DEVICE!/DIRECTORY/NAME.TYPE". This isn't quite the whole story: [See the design document for th gory details if interested][1]. Having the path of the jar file in DEVICE means that I cannot use TRANSLATE-PATHNAME to incorporate the path of the jar in the output translation to a plain file. The best I can do is
(initialize-output-translations '(:output-translations :ignore-inherited-configuration (#p"jar:file:/**/*.jar!/**/*.*" (:home #p"jar-files/**/*.*"))))
which "squashes" all of the output files under one directory irregardless of jar they are specified in , meaning that both "jar:file:/some/thing.jar!/package.lisp" and "jar:file:/a/completely/different.jar!/package.lisp" would have the same output translation.
[1]: http://trac.common-lisp.net/armedbear/browser/trunk/abcl/doc/design/pathname...
So I would ask the ASDF developers to consider extending the output translation DSL to allow something like
(initialize-output-translations '(:output-translations :ignore-inherited-configuration (#p"jar:file:/**/*.jar!/**/*.*" :function SYS::ASDF-JAR-OUTPUT-TRANSLATE)))
or
(initialize-output-translations '(:output-translations :ignore-inherited-configuration (#p"jar:file:/**/*.jar!/**/*.*" :function (lambda (wildstring source) (pathname source)))))
Where the argument following :FUNCTION would either name a symbol for a function or a lambda expression that specifies a function that takes two arguments, the WILDCARD matched and the pathname of the SOURCE that matched. This function would return a pathname suitable for the output location.
I'm working on an implementation of this on your git version as a proof of concept, but haven't gotten much further than getting your output configuration to accept the new syntax. I assume that actually applying the function will be easy, but I am not sure.
And, is there a syntax to specify that a pathname matching a given pattern should have no output location, but should just load the source?

Attached please find a patch to implement the use of an arbitrary output translation function in ASDF2.
An example of the use would be the directive
(#p"jar:file:/**/*.jar!/**/*.*" :function translate-jar-pathname)
which will call the function TRANSLATE-JAR-PATHNAME on a match of the first element of the list. The function will be invoked with two arguments, the first being the matching wildcard, and the second being the pathname to be translated. The function returns the translation.
Hopefully, after review and critique, we can can get something like this in ASDF2.
With the attached patch to abcl trunk, I can successfully use ASDF2 to load ASDF systems in jar files, with the compiled files being output to a translation under :USER-CACHE.
Sorry, haven't had a chance to look closely at asdf2, but wanted to point out that in certain contexts, like running applets, writing to any file system is prohibited. For those cases, it would be nice if it was super-easy to set a flag that says: if there isn't a compiled version, or if it is stale, don't try to compile - just load source.

I may be seeing the same demon everywhere, but I /think/ I see what we would like to be able to do, and why that's very difficult in the existing ASDF.
* What we would like to be able to do is to check and see if the file system is writeable and if it's unwriteable, we should treat the compile operation on the system as having been done.
So it might /seem/ that the following pseudo-cod would work
(defmethod operation-done-p ((op compile-op) (sys jar-system)) (or (filesystem-not-writeable-p sys) (call-next-method)))
... but it won't because
* operation-done-p on a system does /not/ mean "this system has had the operation done on it," but only "any additional compile-op for this system AFTER ITS COMPONENTS HAVE UNDERGONE THE COMPILE-OP are done."
See my earlier email postings on the problems with the ASDF object model and, in particular, the dual meaning of the SYSTEM class object. This was discussed in great length at the time of my rewrite of the TRAVERSE function.

Dear Mark,
Fare's suggestion that I use an output translation based on the jar pathname doesn't quite work, because in our current implementation, the pathname of the jar is stored in DEVICE, separate from the rest of the jar pathname. I extended PATHNAME-MATCH-P to match jars correctly, but I don't see a possible extension of TRANSLATE-PATHNAME.
Couldn't you extend the ABCL pathname matching algorithm to allow for wildcards and all in the device component?
So I would ask the ASDF developers to consider extending the output translation DSL to allow something like
(initialize-output-translations '(:output-translations :ignore-inherited-configuration (#p"jar:file:/**/*.jar!/**/*.*" :function SYS::ASDF-JAR-OUTPUT-TRANSLATE)))
I suggest that either you make (:function foo) a valid second value for an output-translations list, or you make said list accept a &key function argument in addition to its two current positional arguments. But having weird non-standard vararg convention for such lists is probably a bad API. The default function would be TRANSLATE-PATHNAME and the calling convention would be the same.
And, is there a syntax to specify that a pathname matching a given pattern should have no output location, but should just load the source?
You mean, something to force LOAD-SOURCE-OP instead of LOAD-OP? Nope. But I suppose some component class could be defined to do this.

Wildcards do work in DEVICE but you can't currently use unused results of the wildcard matches on the DEVICE components to "carry over" to the translation of the DIRECTORY component. I suppose that's what you were suggesting anyways. There isn't an obviously easy way to implement this in ABCL due to the structure of our code and I need to think through the various permutations, but that doesn't mean that its implementation isn't a win for the end user. I'll see what I can do.
So I would ask the ASDF developers to consider extending the output translation DSL to allow something like
(initialize-output-translations '(:output-translations :ignore-inherited-configuration (#p"jar:file:/**/*.jar!/**/*.*" :function SYS::ASDF-JAR-OUTPUT-TRANSLATE)))
I suggest that either you make (:function foo) a valid second value for an output-translations list, or you make said list accept a&key function argument in addition to its two current positional arguments. But having weird non-standard vararg convention for such lists is probably a bad API. The default function would be TRANSLATE-PATHNAME and the calling convention would be the same.
I'd favor the first proposal, as making :FUNCTION a real key argument would imply that the second positional parameter is optional, whereas it is actually being replaced by the (:FUNCTION ARG) parameter. When I get time to revisit the patch, I'll implement your first proposal.

Thanks, Mark

If you're going to use a lot of such magic DEVICE components, that could be a win.
So I would ask the ASDF developers to consider extending the output translation DSL to allow something like
(initialize-output-translations '(:output-translations :ignore-inherited-configuration (#p"jar:file:/**/*.jar!/**/*.*" :function SYS::ASDF-JAR-OUTPUT-TRANSLATE)))

I'd favor either a keyword argument or :function as a magic marker to be inserted in FIRST position, followed by a function designator (and additionally, parameters to curry?). Unless of course, you symmetrically accept a FUNCTION in first position to denote a "recognize if this matching rule applies".

I would think that we want to preserve the current ability for the user to vistually scan down the list of translations to determine what should match, so I would favor going for your second proposal. It doesn't make sense that there be a match predicate paired with a translation pathname right? So the two new possibilities for output translation lists would be:
("/**/foo/*.*" (:function FOO-OUTPUT-TRANSLATION)) ((:function BAR-PATHNAME-P) (:function BAR-OUTPUT-TRANSLATION))

Attached is a patch against ASDF that allows a user specified function to take the place of TRANSLATE-PATHNAME as the ASDF2 output translation function.
Additionally it adds an ABCL specific extension to ASDF2 that uses this ability by providing the following translations by default
(#p"jar:file:/**/*.jar!/**/*.*" (:function translate-jar-pathname)) (#p"/:jar:file/**/*.*" (:user-cache #p"**/*.*")))
that will map all ASDF loads from jar pathnames to an output location under the per user cache location. This will allow the loading of ASDF systems packaged in jar files which first compiles and then loads FASLs to the local filesystem.
To run this with ABCL you will need to build a custom build of ABCL with the attached patch which is currently necessary to OPEN a jar pathname. This patch is part of a large set of modifications that allow ABCL to open a pathname specified as a url, that I am developing and testing as a unit. These modiictions will be placed in ABCL trunk soon, but first I need to add create more unit tests for the introduced functionality and implement a few more suggestions (like URI encoding functions).
I did not implement Faré's suggestion of including a syntax for a predicate function as the first argument for a output translation pair, because I couldn't come up with a use case in which the current default function PATHNAME-MATCH-P would not work. If someone can come up with such a case, or this deficiency prevents ASDF from accepting this patch, I can have a go at it again.

On MacOSX, and I guess on all non-Windows systems, #p"/:jar:file/**/*.*" equals (make-pathname :type :wild :name :wild :directory '(:absolute ":jar:file" :wild-inferiors))
On Windows, this pathname is parsed differently: the result is a relative directory in a device called "/" (as mentioned in a trac ticket, this causes an error).
Is there a reason why the pathname has to start with "/:"? I changed it to #P"/jar:file/**.*" (and made a similar change inside translate-jar-pathname, from "/:jar:file/" to "/jar:file/"). This seems to work on both macosx and windows (at least I can load asdf systems).
I wonder if something else might be broken with the change.
Cheers,
Carlos

ASDF systems should now load properly in ABCL under windows with [r12644][1]. In addition, the Windows drive letter is now used to properly disambiguate cache entries. Please let me know if you find any other issues, and thanks for the report!

That's great, thanks a lot. I'll check the new version on Monday, when I have access to the machine were I noticed the problem with multiple devices.
