That one I recognize. By any chance do you have your files on a server (like NFS)? If so check to make sure the clocks are synchronized. If the asd file has a time in the future, ASDF goes into an infinite loop. We had an NFS server that had a significant clock drift, and I would get bitten by that a lot. I posted a bug to the ASDF list but no one responded. Liam On Fri, Nov 19, 2010 at 6:04 PM, Mirko Vukovic <mirko.vukovic@gmail.com> wrote:

Unfortunately, I cannot try it right now.  I am having some weird issues with asdf -- it enters into an infinite loop and exceeds the nesting limit.

I will work on this next week.

Complex types are specified as (complex double-float), (complex single-float), etc.  These work:

(map-grid :source #1m(-1d0 -2d0 -3d0)          :element-function #'sqrt          :destination-specification '((foreign-array 3) (complex double-float))) #2m(#C(0.0d0 1.0d0) #C(0.0d0 1.4142135623730951d0)    #C(0.0d0 1.7320508075688772d0))

(make-instance 'vector-complex-double-float :dimensions '(3) :element-type '(complex double-float)) #2m(#C(0.0d0 0.0d0) #C(0.0d0 0.0d0) #C(0.0d0 0.0d0))

Note: you need to pull the latest version of GSD for the first case to work, 307ba9efba fixes a bug in using the type specification.

Hi,

I am reporting this in case it is a gsd bug (it must be a bug somewhere: in my head, my setup, or gsd)

Mapping the `sqrt' function over a vector of negative numbers as follows:

grid> (map-grid :source #1m(-1d0 -2d0 -3d0)                :element-function #'sqrt                :destination-specification '((foreign-array 3) complex-double-float))

gives an error:

Element type COMPLEX-DOUBLE-FLOAT not permitted.   [Condition of type SIMPLE-ERROR]

I traced it to a `make-instance' statement.

I also tried to instantiate a vector-complex-double-float object

grid> (make-instance 'vector-complex-double-float                     :dimensions '(3)                     :element-type 'complex-double-float)

that resulted in the same error message.

FWIW, I downloaded the last gsd patch of Nov. 22, and the asd systems load cleanly. No more infinite loops. My hypothesis was that the soft links in the gsd directory of grid.asd and foreign-array.asd to their location in the gsd/grid and gsd/foreign-array was the culprit. But I tested that on a separate tree, and asdf2 worked fine. I tried downloading and installing the version of Nov. 21, and this time it loaded up cleanly too. So, it is not something in the files.

No, the file was local.   The only remotely relevant item is that the file timestamps were those from the git repository (for example, if I download a version a few days old, the file timestamps will be from November 8 say).

The following is from hazy (possibly incorrect memory): I was able to install grid by cd-in into gsd/grid and doing asdf from there.  Then when I tried to install foreign-array from gsd I got asdf looping again.  I have ASDF2 searching these directories recursively (as a tree).  (As I said, hazy/incorrect recollection as I was in a hurry to head home).  I will verify that next week.

I am using ASDF2
