+
+This file lists all bug fixes, changes, etc., made since the AWK book
+was sent to the printers in August, 1987.
+
+May 23, 2010:
+ fixed long-standing overflow bug in run.c; many thanks to
+ nelson beebe for spotting it and providing the fix.
+
+ fixed bug that didn't parse -vd=1 properly; thanks to santiago
+ vila for spotting it.
+
+Feb 8, 2010:
+ i give up. replaced isblank with isspace in b.c; there are
+ no consistent header files.
+
+Nov 26, 2009:
+ fixed a long-standing issue with when FS takes effect. a
+ change to FS is now noticed immediately for subsequent splits.
+
+ changed the name getline() to awkgetline() to avoid yet another
+ name conflict somewhere.
+
+Feb 11, 2009:
+ temporarily for now defined HAS_ISBLANK, since that seems to
+ be the best way through the thicket. isblank arrived in C99,
+ but seems to be arriving at different systems at different
+ times.
+
+Oct 8, 2008:
+ fixed typo in b.c that set tmpvec wrongly. no one had ever
+ run into the problem, apparently. thanks to alistair crooks.
+
+Oct 23, 2007:
+ minor fix in lib.c: increase inputFS to 100, change malloc
+ for fields to n+1.
+
+ fixed memory fault caused by out of order test in setsval.
+
+ thanks to david o'brien, freebsd, for both fixes.
+
+May 1, 2007:
+ fiddle in makefile to fix for BSD make; thanks to igor sobrado.
+
+Mar 31, 2007:
+ fixed some null pointer refs calling adjbuf.
+
+Feb 21, 2007:
+ fixed a bug in matching the null RE in sub and gsub. thanks to al aho
+ who actually did the fix (in b.c), and to wolfgang seeberg for finding
+ it and providing a very compact test case.
+
+ fixed quotation in b.c; thanks to Hal Pratt and the Princeton Dante
+ Project.
+
+ removed some no-effect asserts in run.c.
+
+ fiddled maketab.c to not complain about bison-generated values.
+
+ removed the obsolete -V argument; fixed --version to print the
+ version and exit.
+
+ fixed wording and an outright error in the usage message; thanks to igor
+ sobrado and jason mcintyre.
+
+ fixed a bug in -d that caused core dump if no program followed.
+
+Jan 1, 2007:
+ dropped mac.code from makefile; there are few non-MacOSX
+ mac's these days.
+
+Jan 17, 2006:
+ system() not flagged as unsafe in the unadvertised -safe option.
+ found it while enhancing tests before shipping the ;login: article.
+ practice what you preach.
+
+ removed the 9-years-obsolete -mr and -mf flags.
+
+ added -version and --version options.
+
+ core dump on linux with BEGIN {nextfile}, now fixed.
+
+ removed some #ifdef's in run.c and lex.c that appear to no
+ longer be necessary.
+
+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
+ was longer than the number of states triggered a failure to initialize
+ the machine properly. many thanks to moinak ghosh for not only finding
+ this one but for providing a fix, in some of the most mysterious
+ code known to man.
+
+ fixed a storage leak in call() that appears to have been there since
+ 1983 or so -- a function without an explicit return that assigns a
+ string to a parameter leaked a Cell. thanks to moinak ghosh for
+ spotting this very subtle one.
+
+Jul 31, 2003:
+ fixed, thanks to andrey chernov and ruslan ermilov, a bug in lex.c
+ that mis-handled the character 255 in input. (it was being compared
+ to EOF with a signed comparison.)
+
+Jul 29, 2003:
+ fixed (i think) the long-standing botch that included the beginning of
+ line state ^ for RE's in the set of valid characters; this led to a
+ variety of odd problems, including failure to properly match certain
+ regular expressions in non-US locales. thanks to ruslan for keeping
+ at this one.
+
+Jul 28, 2003:
+ n-th try at getting internationalization right, with thanks to volker
+ kiefel, arnold robbins and ruslan ermilov for advice, though they
+ should not be blamed for the outcome. according to posix, "." is the
+ radix character in programs and command line arguments regardless of
+ the locale; otherwise, the locale should prevail for input and output
+ of numbers. so it's intended to work that way.
+
+ i have rescinded the attempt to use strcoll in expanding shorthands in
+ regular expressions (cclenter). its properties are much too
+ surprising; for example [a-c] matches aAbBc in locale en_US but abBcC
+ in locale fr_CA. i can see how this might arise by implementation
+ but i cannot explain it to a human user. (this behavior can be seen
+ in gawk as well; we're leaning on the same library.)
+
+ the issue appears to be that strcoll is meant for sorting, where
+ merging upper and lower case may make sense (though note that unix
+ sort does not do this by default either). it is not appropriate
+ for regular expressions, where the goal is to match specific
+ patterns of characters. in any case, the notations [:lower:], etc.,
+ are available in awk, and they are more likely to work correctly in
+ most locales.
+
+ a moratorium is hereby declared on internationalization changes.
+ i apologize to friends and colleagues in other parts of the world.
+ i would truly like to get this "right", but i don't know what
+ that is, and i do not want to keep making changes until it's clear.
+
+Jul 4, 2003:
+ fixed bug that permitted non-terminated RE, as in "awk /x".
+
+Jun 1, 2003:
+ subtle change to split: if source is empty, number of elems
+ is always 0 and the array is not set.
+
+Mar 21, 2003:
+ added some parens to isblank, in another attempt to make things
+ internationally portable.
+
+Mar 14, 2003:
+ the internationalization changes, somewhat modified, are now
+ reinstated. in theory awk will now do character comparisons
+ and case conversions in national language, but "." will always
+ be the decimal point separator on input and output regardless
+ of national language. isblank(){} has an #ifndef.
+
+ this no longer compiles on windows: LC_MESSAGES isn't defined
+ in vc6++.
+
+ fixed subtle behavior in field and record splitting: if FS is
+ a single character and RS is not empty, \n is NOT a separator.
+ this tortuous reading is found in the awk book; behavior now
+ matches gawk and mawk.
+
+Dec 13, 2002:
+ for the moment, the internationalization changes of nov 29 are
+ rolled back -- programs like x = 1.2 don't work in some locales,
+ because the parser is expecting x = 1,2. until i understand this
+ better, this will have to wait.
+
+Nov 29, 2002:
+ modified b.c (with tiny changes in main and run) to support
+ locales, using strcoll and iswhatever tests for posix character
+ classes. thanks to ruslan ermilov (ru%freebsd.org@localhost) for code.
+ the function isblank doesn't seem to have propagated to any
+ header file near me, so it's there explicitly. not properly
+ tested on non-ascii character sets by me.
+
+Jun 28, 2002:
+ modified run/format() and tran/getsval() to do a slightly better
+ job on using OFMT for output from print and CONVFMT for other
+ number->string conversions, as promised by posix and done by
+ gawk and mawk. there are still places where it doesn't work
+ right if CONVFMT is changed; by then the STR attribute of the
+ variable has been irrevocably set. thanks to arnold robbins for
+ code and examples.
+
+ fixed subtle bug in format that could get core dump. thanks to
+ Jaromir Dolecek <jdolecek%NetBSD.org@localhost> for finding and fixing.
+ minor cleanup in run.c / format() at the same time.
+
+ added some tests for null pointers to debugging printf's, which
+ were never intended for external consumption. thanks to dave
+ kerns (dkerns%lucent.com@localhost) for pointing this out.
+
+ GNU compatibility: an empty regexp matches anything (thanks to
+ dag-erling smorgrav, des%ofug.org@localhost). subject to reversion if
+ this does more harm than good.
+
+ pervasive small changes to make things more const-correct, as
+ reported by gcc's -Wwrite-strings. as it says in the gcc manual,
+ this may be more nuisance than useful. provoked by a suggestion
+ and code from arnaud desitter, arnaud%nimbus.geog.ox.ac.uk@localhost
+
+ minor documentation changes to note that this now compiles out
+ of the box on Mac OS X.
+
+Feb 10, 2002:
+ changed types in posix chars structure to quiet solaris cc.
+
+Jan 1, 2002:
+ fflush() or fflush("") flushes all files and pipes.
+
+ length(arrayname) returns number of elements; thanks to
+ arnold robbins for suggestion.
+
+ added a makefile.win to make it easier to build on windows.
+ based on dan allen's buildwin.bat.
+
+Nov 16, 2001:
+ added support for posix character class names like [:digit:],
+ which are not exactly shorter than [0-9] and perhaps no more
+ portable. thanks to dag-erling smorgrav for code.
+
+Feb 16, 2001:
+ removed -m option; no longer needed, and it was actually
+ broken (noted thanks to volker kiefel).
+
+Feb 10, 2001:
+ fixed an appalling bug in gettok: any sequence of digits, +,-, E, e,
+ and period was accepted as a valid number if it started with a period.
+ this would never have happened with the lex version.
+
+ other 1-character botches, now fixed, include a bare $ and a
+ bare " at the end of the input.
+
+Feb 7, 2001:
+ more (const char *) casts in b.c and tran.c to silence warnings.
+
+Nov 15, 2000:
+ fixed a bug introduced in august 1997 that caused expressions
+ like $f[1] to be syntax errors. thanks to arnold robbins for
+ noticing this and providing a fix.
