This file lists all bug fixes, changes, etc., made since the AWK book
|
||||
was sent to the printers in August, 1987.

|

Apr 24, 2005:
|
||||
modified lib.c so that values of $0 et al are preserved in the END
|
||||
block, apparently as required by posix. thanks to havard eidnes
|
||||
for the report and code.
|
||||
|
||||
Jan 14, 2005:
|
||||
fixed infinite loop in parsing, originally found by brian tsang.
|
||||
thanks to arnold robbins for a suggestion that started me
|
||||
rethinking it.
|
||||
|
||||
Dec 31, 2004:
|
||||
prevent overflow of -f array in main, head off potential error in
|
||||
call of SYNTAX(), test malloc return in lib.c, all with thanks to
|
||||
todd miller.
|
||||
|
||||
Dec 22, 2004:
|
||||
cranked up size of NCHARS; coverity thinks it can be overrun with
|
||||
smaller size, and i think that's right. added some assertions to b.c
|
||||
to catch places where it might overrun. the RE code is still fragile.
|
||||
|
||||
Dec 5, 2004:
|
||||
fixed a couple of overflow problems with ridiculous field numbers:
|
||||
e.g., print $(2^32-1). thanks to ruslan ermilov, giorgos keramidas
|
||||
and david o'brien at freebsd.org for patches. this really should
|
||||
be re-done from scratch.
|
||||
|
||||
Nov 21, 2004:
|
||||
fixed another 25-year-old RE bug, in split. it's another failure
|
||||
to (re-)initialize. thanks to steve fisher for spotting this and
|
||||
providing a good test case.
|
||||
|
||||
Nov 22, 2003:
|
||||
fixed a bug in regular expressions that dates (so help me) from 1977;

it's been there from the beginning. an anchored longest match that
