Changes:
improve hash function by using FNV-1 algorithm (patch/discussion by
Jim Mellander). This greatly improves speed for accessing arrays
with a large number of distinct keys; however the unsorted order in
"for" loops will differ.
add "internal regex" or "external regex" string to version message
to allow scripting based on support for embedded nulls.
drop obsolete CF_MAWK_PROG_GCC and CF_MAWK_PROG_YACC macros from
configure script (report by Mike Frysinger).
fixes to allow build outside source-tree (report by Mike Frysinger).
correct logic in scan.c to handle expression "[[]" (report by
Aleksey Cheusov).
add MAWK_LONG_OPTIONS feature to allow mawk to ignore long options
which are not implemented.
two changes for embedded nulls, allows FS to be either a null or
contain a character class with null, e.g., '\000' or '[ \000]':
+ modify built-in regular expression functions to accept embedded
nulls.
+ modify input reader FINgets() to accept embedded nulls in data
read from files. Data read from standard input is line-buffered,
and is still null-terminated.
update config.guess and config.sub
Mike Brennan's awk clone.
It's fast (faster than gawk), and relatively small.
After 13 years of stagnation, mawk now has a new maintainer. Lots of bug fixes.
Most pkgsrc patches were applied.
Changes by Thomas E Dickey <dickey@invisible-island.net>
20090820
minor portability/standards fixes for examples/hical
add WHINY_USERS sorted-array feature, for compatibility with gawk
(patch by Aharon Robbins).
correct lower-limit for d_to_U() function, which broke conversion of
zero in "%x" format, added in fix for Debian #303825 (report by Masami
Hiramatsu).
modify "%s" and "%c" formatting in printf/sprintf commands to ensure
that "%02s" does not do zero-padding, for standards conformance
(discussion with Aharon Robbins, Mike Brennan, prompted by Debian
#339799).
20090728
add fallback definitions for GCC_NORETURN and GCC_UNUSED to build with
non-gcc compilers (report by Jan Wells).
20090727
add check/fix to prevent gsub from recurring to modify on a substring
of the current line when the regular expression is anchored to the
beginning of the line; fixes gawk's anchgsub testcase.
add check for implicit concatenation mistaken for exponent; fixes
gawk's hex testcase.
add character-classes to built-in regular expressions.
add 8-bit locale support
20090726
improve configure checks for MAX__UINT.
add a check for infinite loop in REmatch(), to work with gawk's noloop1
testcase.
modify logic to allow setting RS to an explicit null character, e.g.,
RS="\0"
(Ubuntu #400409).
modify workaround for (incorrect) scripts which use a zero-parameter
for substr to ensure the overall length of the result stays the same.
For example, from makewhatis:
filename_no_gz = substr(filename, 0, RSTART - 1);
move regular-expression files into main directory to simplify building
using configure --srcdir and VPATH.
modify internal functions for gsub() to handle a case from makewhatis
script from man 1.6f which substitutes embedded zero bytes to a
different value (report by Gabor Z Papp).
change default for configure --with-builtin-regex to prefer the
builtin regular expressions. They are incomplete, but POSIX regular
expressions cannot match nulls embedded in strings.
require standard C compiler; converted to ANSI C.
rename #define'd SV_SIGINFO to MAWK_SV_SIGINFO to avoid predefined
name on Mac OS X (report on comp.lang.awk).
revise configure script to use conventional scheme for generating
config.h
20090721
port to cygwin, modifying test-script to work with executable-suffix
and fp-exception code to allow const in declaration.
20090712
update patch-date.
fix Debian #127293 "mawk does not understand unescaped '/' in character
classes", noting that gawk 3.1.6 also has problems with this area.
drop support for varargs; use stdarg only.
add tags rule to makefile.
rename configure option "--with-local-regexp" to "--with-builtin-regex"
add build-fix from NetBSD port: enable vax FP support when
defined(__vax__) as well as BSD43_VAX. from ragge.
add configure --disable-echo option
identify updated files with "MawkId" keywords, retaining old log
comments for reference. Ongoing changes are recorded here.
update maintainer email address.
20090711
use conventional install/uninstall rules in makefile.
add install-sh script, mkdirs.sh, config.guess and config.sub
add $DESTDIR support to makefile
add uninstall make-target
add configure --enable-warnings option (fixed some warnings...)
update configure script to autoconf 2.52 to permit cross-compiles.
drop config.user file; replace with conventional autoconf --prefix, etc.
fill-in CA_REC.type in two places in parse.y which weren't initialized.
fix Debian #38353 (absent expression on last part of "for" statement
caused core-dump).
fix Debian #303825 (printf %x clamps numbers to signed range rather
than unsigned range).
apply fix from Debian #355966 (null-pointer check in is_string_split())
apply fix from Debian #391051 (limit-check in scan.c)
20090709
add patch from Aleksey Cheusov for external regexp libraries
(originally comp.lang.awk June 15 2005, also cited in Debian #355442
March 6, 2006).
20090705
fixes to build on BeOS (if LIBS is set to -lroot), and QNX (redefinition
of setmode).
20080909
fix gcc 4.3.1 -Wall warnings
transform mawk.ac.m4 to aclocal.m4, renaming macros to use "CF_" or
"CF_MAWK_" prefixes depending on their reusability. Modified macros
to use quoting consistent with recent autoconf versions.
regenerate configure with autoconf version 2.13.20030927
regenerate parse.c with byacc - 1.9 20080827
ifdef'd prototypes in nstd.h which belong to stdlib.h, string.h to
use standard C by default.
source-in Debian patches 01-08 (see below). Changes for 20080909 fix
Debian #496980 as well.
