annotate src/getpagesize.h @ 5916:1152e0091f8c
Avoid confusion about ELC vs. source file encoding, #'load, #'load-internal.
lisp/ChangeLog addition:
2015-06-03 Aidan Kehoe <kehoea@parhasard.net>
* code-files.el (load):
Revise this to respect load-ignore-out-of-date-elc-files, rather
than leaving that to #'load-internal. Avoids a corner case where
the source and the compiled file have different, incompatible
encodings.
Move the call to #'substitute-in-file-name here.
No longer check for a zero-length filename, since #'load-internal
no longer chokes on same and errors correctly.
src/ChangeLog addition:
2015-06-03 Aidan Kehoe <kehoea@parhasard.net>
* lread.c (Fload_internal):
Delegate calling the handler and #'substitute-in-file-name to #'load.
Error correctly with a zero-length file name, instead of giving a
bus error on my machine.
Delegate the check for out-of-date ELC files to #'load,
avoiding a bug where the encoding of the ELC file and the source
file differed.
* lread.c (PRINT_LOADING_MESSAGE_1):
This is simplified, now we no longer have to talk about
out-of-date ELC files.
tests/ChangeLog addition:
2015-06-03 Aidan Kehoe <kehoea@parhasard.net>
* automated/file-tests.el:
Gross sanity check for #'load and #'load-internal with a
zero-length FILE, something that crashed until today.
