#227 closed defect (fixed)

Hemlock shouldn't crash CCL if it runs into an attribute line it doesn't understand

(From GB e-mail response to Ron Garret)

All that I can tell is that it's trying to write a warning to the echo area to the effect that it doesn't understand the "Syntax:" file option; I'm not sure that the echo area even exists at this point. (It's dying in the method #/readFromURL:ofType:error: on hemlock-editor-document; this code is running on the event thread, and whatever its notion of "the echo area" is, it probably isn't correct.)

If it's going to try to parse the attribute line and if it's going to do someting other than silently ignore attributes that it doesn't understand, it should probably do that parsing a little later (and, in the current model, it should do that on the right thread.)

Correction: It's (apparently) not CFFI. The problem seems to be trying to open a file containing the following modeline:

;;; -*- Mode: LISP; Syntax: ANSI-Common-Lisp; Package: CL-USER; -*-

Trying to open a file with this modeline dumps a whole bunch of error messages to the console and results in a broken Lisp.

FWIW this is fixed in the 'event-ide' branch, and which should get migrated into the trunk in a few weeks.
