Hi guys,
if a file variable is a list longer than a certain size, then it's
ignored on file loading. Test case follows:
- start "emacs -Q"
- M-: (add-file-local-variable 'v1 (make-list 2000 1)) RET
- C-x C-w example01.el RET
- close Emacs and restart "emacs -Q"
- C-x C-f example01.el RET
- bad behaviour: at this point a confirm message to load the file
variable should have appeared ("... safe variables blah blah... do you
want to apply it? y/n/!") but it does not, and the variable is not
initialized
Further observations:
- if you replay this same test with a shorter v1, for example lowering
"2000" to "1000", then the behaviour will be fine: the confirm
message will appear and inspection of the variable will show correct
value.
- it doesn't seem to depend on the max length of a single text line:
you get the error even when you re-run a similar test that saves two
file-local variables v1 and v2, each being "(make-list 1000 1)".
Does the test reproduce in the same way on your workstation? Do you
think it's a bug, or am I just hitting some well-known hard limit?
Thanks for any hint or clarification, kindest regards.
Andrea
