Re: file-lock library on lw64-linux

Hi Arnold,

I've actually tracked the culprit down. The problem shows up when I default
to utf-8 file handling like this:

(defun utf-8-file-encoding (pathname ef-spec buffer length)
  (declare (ignore pathname buffer length))
  (system:merge-ef-specs ef-spec :utf-8))

(setq system:*file-encoding-detection-algorithm*
      (substitute 'utf-8-file-encoding
                  'system:locale-file-encoding
                  system:*file-encoding-detection-algorithm*))

I'm just trying to figure out if I'm actually taking the wrong approach
with my file handling or if I should take a different approach to using the
file-lock lib...

At least the world makes sense now, I thought it was kinda wild that
something this fundamental went wrong. I clicked when I realised that it
was checking ef-stream...

Eben Bruyns
