Reject filenames containing NUL bytes.

2020-12-23T11:00:46+00:00

Such filenames are dangerous, as Emacs would silently only use the
part up to the first NUL byte.  Reject them explicitly instead.

* src/coding.c (encode_file_name_1): New helper function.
(encode_file_name): Check that encoded filename doesn't contain a
NUL byte.
(syms_of_coding): Define 'filenamep' symbol.

test.

* etc/NEWS: Document change.

Re-order the items in `profiler-report' output.

2020-12-22T12:06:21+00:00

Putting the usage figures first on the line will eliminate the truncation of
function names.

lisp/profiler.el (profiler-version): Change to "28.1".
(profiler-format): Enhance, so that a width of zero means print the string
without padding or truncation.
(profiler-report-cpu-line-format, profiler-report-memory-line-format): Amend
for the new layout.  The number of places for the cpu samples has been reduced
from 19 to 12 (enough for ~30 years at 1,000 samples per second).
(profiler-report-line-format, profiler-report-describe-entry): Amend for the
new order of arguments to profiler-format.

etc/NEWS (Specialized Modes): Add an entry documenting this change.

doc/lispref/debugging.texi (Profiling): Describe the new ordering of the items
in place of the old ordering.
