Subject: [clpython-devel] import gives UnexpectedEofError
Message-ID: <87hb7it5j9.fsf@science.uva.nl>

I'm running into an error while trying to get CLPython up and running. 

The test suite fails on the first Python import test with an
UnexpectedEofError. Any other attempt at importing gives the same error.
For example these three lines of code give the error as below:

    (ql:quickload "clpython")
    (push #p"clpython-20110219-git/test/data" *CLPYTHON-MODULE-SEARCH-PATHS*)
    (clpython:run "import bar")
    
    ;; Parsing #P"clpython-20110219-git/test/data/bar.py" into #P"clpython-20110219-git/test/data/bar.py.lisp"
    
    ;; Error occured while reading input with the Python readtable:
    ;;   UnexpectedEofError: Unexpected end of file.
    ;; Standard IO syntax (*readtable* etc) has been activated to enable debugging.
    
    debugger invoked on a CLPYTHON.USER.BUILTIN.TYPE.EXCEPTION:|UnexpectedEofError| in thread #<THREAD "initial thread" RUNNING {10029994E1}>: UnexpectedEofError: Unexpected end of file.


It's the most recent quicklisp version of CLPython on Linux.

SBCL 1.0.49
quicklisp version 2011051901
clpython-20110219-git
Python 2.7.2
Linux 2.6.39

Thanks for the report. It's caused by a bug in SBCL that I had
encountered earlier, but had forgotten to commit a workaround for:
 https://bugs.launchpad.net/sbcl/+bug/690408

I've committed the workaround now:
 https://github.com/franzinc/cl-python/commit/6008967cbb2ee690a087120a8170ca08ec354715

Until this version is included in QuickLisp I'm not sure what the
proper way to patch your CLPython within QuickLisp is, but modifying
quicklisp/dists/quicklisp/software/clpython-20110619-git/util/readtable.lisp
seems to work.

Many thanks for the quick turnaround, Willem. 

I sidestepped quicklisp, pulled the latest git of cl-python and hooked it
in using asdf. It works fine.

Groeten,
