many thanks to 50221381Sru nelson beebe for spotting it and providing the fix. 51221381Sru 52221381Sru fixed bug that didn't parse -vd=1 properly; thanks to santiago 53221381Sru vila for spotting it. 54221381Sru 55221381SruFeb 8, 2010: 56221381Sru i give up. replaced isblank with isspace in b.c; there are 57221381Sru no consistent header files. 58221381Sru 59201951SruNov 26, 2009: 60201951Sru fixed a long-standing issue with when FS takes effect. a 61201951Sru change to FS is now noticed immediately for subsequent splits. 62201951Sru 63201951Sru changed the name getline() to awkgetline() to avoid yet another 64201951Sru name conflict somewhere. 65201951Sru 66201951SruFeb 11, 2009: 67201951Sru temporarily for now defined HAS_ISBLANK, since that seems to 68201951Sru be the best way through the thicket. isblank arrived in C99, 69201951Sru but seems to be arriving at different systems at different 70201951Sru times. 71201951Sru 72201951SruOct 8, 2008: 73201951Sru fixed typo in b.c that set tmpvec wrongly. no one had ever 74201951Sru run into the problem, apparently. thanks to alistair crooks. 75201951Sru 76172958SobrienOct 23, 2007: 77172958Sobrien minor fix in lib.c: increase inputFS to 100, change malloc 78172958Sobrien for fields to n+1. 79172958Sobrien 80172958Sobrien fixed memory fault caused by out of order test in setsval. 81172958Sobrien 82172958Sobrien thanks to david o'brien, freebsd, for both fixes. 83172958Sobrien 84170331SrafanMay 1, 2007: 85170331Srafan fiddle in makefile to fix for BSD make; thanks to igor sobrado. 86170331Srafan 87170331SrafanMar 31, 2007: 88170331Srafan fixed some null pointer refs calling adjbuf. 89170331Srafan 90170331SrafanFeb 21, 2007: 91170331Srafan fixed a bug in matching the null RE in sub and gsub. thanks to al aho 92170331Srafan who actually did the fix (in b.c), and to wolfgang seeberg for finding 93170331Srafan it and providing a very compact test case. 94170331Srafan 95170331Srafan fixed quotation in b.c; thanks to Hal Pratt and the Princeton Dante 96170331Srafan Project. 97170331Srafan 98170331Srafan removed some no-effect asserts in run.c. 99170331Srafan 100170331Srafan fiddled maketab.c to not complain about bison-generated values. 101170331Srafan 102170331Srafan removed the obsolete -V argument; fixed --version to print the 103170331Srafan version and exit. 104170331Srafan 105170331Srafan fixed wording and an outright error in the usage message; thanks to igor 106170331Srafan sobrado and jason mcintyre. 107170331Srafan 108170331Srafan fixed a bug in -d that caused core dump if no program followed. 109170331Srafan 110170331SrafanJan 1, 2007: 111170331Srafan dropped mac.code from makefile; there are few non-MacOSX 112170331Srafan mac's these days. 113170331Srafan 114170331SrafanJan 17, 2006: 115170331Srafan system() not flagged as unsafe in the unadvertised -safe option. 116170331Srafan found it while enhancing tests before shipping the ;login: article. 117170331Srafan practice what you preach. 118170331Srafan 119170331Srafan removed the 9-years-obsolete -mr and -mf flags. 120170331Srafan 121170331Srafan added -version and --version options. 122170331Srafan 123170331Srafan core dump on linux with BEGIN {nextfile}, now fixed. 124170331Srafan 125170331Srafan removed some #ifdef's in run.c and lex.c that appear to no 126170331Srafan longer be necessary. 127170331Srafan 128146299SruApr 24, 2005: 129146299Sru modified lib.c so that values of $0 et al are preserved in the END 130146299Sru block, apparently as required by posix. thanks to havard eidnes 131146299Sru for the report and code. 132146299Sru 133146299SruJan 14, 2005: 134146299Sru fixed infinite loop in parsing, originally found by brian tsang. 135146299Sru thanks to arnold robbins for a suggestion that started me 136146299Sru rethinking it. 137146299Sru 138146299SruDec 31, 2004: 139146299Sru prevent overflow of -f array in main, head off potential error in 140146299Sru call of SYNTAX(), test malloc return in lib.c, all with thanks to 141146299Sru todd miller. 142146299Sru 143146299SruDec 22, 2004: 144146299Sru cranked up size of NCHARS; coverity thinks it can be overrun with 145146299Sru smaller size, and i think that's right. added some assertions to b.c 146146299Sru to catch places where it might overrun. the RE code is still fragile. 147146299Sru 148146299SruDec 5, 2004: 149146299Sru fixed a couple of overflow problems with ridiculous field numbers: 150146299Sru e.g., print $(2^32-1). thanks to ruslan ermilov, giorgos keramidas 151146299Sru and david o'brien at freebsd.org for patches. this really should 152146299Sru be re-done from scratch. 153146299Sru 154146299SruNov 21, 2004: 155146299Sru fixed another 25-year-old RE bug, in split. it's another failure 156146299Sru to (re-)initialize. thanks to steve fisher for spotting this and 157146299Sru providing a good test case. 158146299Sru 159125601SruNov 22, 2003: 160125601Sru fixed a bug in regular expressions that dates (so help me) from 1977; 161125601Sru it's been there from the beginning. an anchored longest match that 162125601Sru was longer than the number of states triggered a failure to initialize 163125601Sru the machine properly. many thanks to moinak ghosh for not only finding 164125601Sru this one but for providing a fix, in some of the most mysterious 165125601Sru code known to man. 166125601Sru 167125601Sru fixed a storage leak in call() that appears to have been there since 168125601Sru 1983 or so -- a function without an explicit return that assigns a 169125601Sru string to a parameter leaked a Cell. thanks to moinak ghosh for 170125601Sru spotting this very subtle one. 171125601Sru 172125601SruJul 31, 2003: 173125601Sru fixed, thanks to andrey chernov and ruslan ermilov, a bug in lex.c 174125601Sru that mis-handled the character 255 in input. (it was being compared 175125601Sru to EOF with a signed comparison.) 176125601Sru 177118194SruJul 29, 2003: 178118194Sru fixed (i think) the long-standing botch that included the beginning of 179118194Sru line state ^ for RE's in the set of valid characters; this led to a 180118194Sru variety of odd problems, including failure to properly match certain 181118194Sru regular expressions in non-US locales. thanks to ruslan for keeping 182118194Sru at this one. 183118194Sru 184118194SruJul 28, 2003: 185118194Sru n-th try at getting internationalization right, with thanks to volker 186118194Sru kiefel, arnold robbins and ruslan ermilov for advice, though they 187118194Sru should not be blamed for the outcome. according to posix, "." is the 188118194Sru radix character in programs and command line arguments regardless of 189118194Sru the locale; otherwise, the locale should prevail for input and output 190118194Sru of numbers. so it's intended to work that way. 191118194Sru 192118194Sru i have rescinded the attempt to use strcoll in expanding shorthands in 193118194Sru regular expressions (cclenter). its properties are much too 194118194Sru surprising; for example [a-c] matches aAbBc in locale en_US but abBcC 195118194Sru in locale fr_CA. i can see how this might arise by implementation 196118194Sru but i cannot explain it to a human user. (this behavior can be seen 197118194Sru in gawk as well; we're leaning on the same library.) 198118194Sru 199118194Sru the issue appears to be that strcoll is meant for sorting, where 200118194Sru merging upper and lower case may make sense (though note that unix 201118194Sru sort does not do this by default either). it is not appropriate 202118194Sru for regular expressions, where the goal is to match specific 203118194Sru patterns of characters. in any case, the notations [:lower:], etc., 204118194Sru are available in awk, and they are more likely to work correctly in 205118194Sru most locales. 206118194Sru 207118194Sru a moratorium is hereby declared on internationalization changes. 208118194Sru i apologize to friends and colleagues in other parts of the world. 209118194Sru i would truly like to get this "right", but i don't know what 210118194Sru that is, and i do not want to keep making changes until it's clear. 211118194Sru 212118194SruJul 4, 2003: 213118194Sru fixed bug that permitted non-terminated RE, as in "awk /x". 214118194Sru 215118194SruJun 1, 2003: 216118194Sru subtle change to split: if source is empty, number of elems 217118194Sru is always 0 and the array is not set. 218118194Sru 219118194SruMar 21, 2003: 220118194Sru added some parens to isblank, in another attempt to make things 221118194Sru internationally portable. 222118194Sru 223112336SobrienMar 14, 2003: 224112336Sobrien the internationalization changes, somewhat modified, are now 225112336Sobrien reinstated. in theory awk will now do character comparisons 226112336Sobrien and case conversions in national language, but "." will always 227112336Sobrien be the decimal point separator on input and output regardless 228112336Sobrien of national language. isblank(){} has an #ifndef. 229112336Sobrien 230112336Sobrien this no longer compiles on windows: LC_MESSAGES isn't defined 231112336Sobrien in vc6++. 232112336Sobrien 233112336Sobrien fixed subtle behavior in field and record splitting: if FS is 234112336Sobrien a single character and RS is not empty, \n is NOT a separator. 235112336Sobrien this tortuous reading is found in the awk book; behavior now 236112336Sobrien matches gawk and mawk. 237112336Sobrien 238108072SobrienDec 13, 2002: 239108072Sobrien for the moment, the internationalization changes of nov 29 are 240108072Sobrien rolled back -- programs like x = 1.2 don't work in some locales, 241108072Sobrien because the parser is expecting x = 1,2. until i understand this 242108072Sobrien better, this will have to wait. 243108072Sobrien 244107806SobrienNov 29, 2002: 245107806Sobrien modified b.c (with tiny changes in main and run) to support 246107806Sobrien locales, using strcoll and iswhatever tests for posix character 247107806Sobrien classes. thanks to ruslan ermilov (ru@freebsd.org) for code. 248107806Sobrien the function isblank doesn't seem to have propagated to any 249107806Sobrien header file near me, so it's there explicitly. not properly 250107806Sobrien tested on non-ascii character sets by me. 251107806Sobrien 252107806SobrienJun 28, 2002: 253107806Sobrien modified run/format() and tran/getsval() to do a slightly better 254107806Sobrien job on using OFMT for output from print and CONVFMT for other 255107806Sobrien number->string conversions, as promised by posix and done by 256107806Sobrien gawk and mawk. there are still places where it doesn't work 257107806Sobrien right if CONVFMT is changed; by then the STR attribute of the 258107806Sobrien variable has been irrevocably set. thanks to arnold robbins for 259107806Sobrien code and examples. 260107806Sobrien 261107806Sobrien fixed subtle bug in format that could get core dump. thanks to 262107806Sobrien Jaromir Dolecek <jdolecek@NetBSD.org> for finding and fixing. 263107806Sobrien minor cleanup in run.c / format() at the same time. 264107806Sobrien 265107806Sobrien added some tests for null pointers to debugging printf's, which 266107806Sobrien were never intended for external consumption. thanks to dave 267107806Sobrien kerns (dkerns@lucent.com) for pointing this out. 268107806Sobrien 269107806Sobrien GNU compatibility: an empty regexp matches anything (thanks to 270107806Sobrien dag-erling smorgrav, des@ofug.org). subject to reversion if 271107806Sobrien this does more harm than good. 272107806Sobrien 273107806Sobrien pervasive small changes to make things more const-correct, as 274107806Sobrien reported by gcc's -Wwrite-strings. as it says in the gcc manual, 275107806Sobrien this may be more nuisance than useful. provoked by a suggestion 276107806Sobrien and code from arnaud desitter, arnaud@nimbus.geog.ox.ac.uk 277107806Sobrien 278107806Sobrien minor documentation changes to note that this now compiles out 279107806Sobrien of the box on Mac OS X. 280107806Sobrien 28190902SdesFeb 10, 2002: 28290902Sdes changed types in posix chars structure to quiet solaris cc. 28390902Sdes 28490902SdesJan 1, 2002: 28590902Sdes fflush() or fflush("") flushes all files and pipes. 28690902Sdes 28790902Sdes length(arrayname) returns number of elements; thanks to 28890902Sdes arnold robbins for suggestion. 28990902Sdes 29090902Sdes added a makefile.win to make it easier to build on windows. 29190902Sdes based on dan allen's buildwin.bat. 29290902Sdes 29390902SdesNov 16, 2001: 29490902Sdes added support for posix character class names like [:digit:], 29590902Sdes which are not exactly shorter than [0-9] and perhaps no more 29690902Sdes portable. thanks to dag-erling smorgrav for code. 29790902Sdes 29890902SdesFeb 16, 2001: 29990902Sdes removed -m option; no longer needed, and it was actually 30090902Sdes broken (noted thanks to volker kiefel). 30190902Sdes 30290902SdesFeb 10, 2001: 30390902Sdes fixed an appalling bug in gettok: any sequence of digits, +,-, E, e, 30490902Sdes and period was accepted as a valid number if it started with a period. 30590902Sdes this would never have happened with the lex version. 30690902Sdes 30790902Sdes other 1-character botches, now fixed, include a bare $ and a 30890902Sdes bare " at the end of the input. 30990902Sdes 31090902SdesFeb 7, 2001: 31190902Sdes more (const char *) casts in b.c and tran.c to silence warnings. 31290902Sdes 31385587SobrienNov 15, 2000: 31485587Sobrien fixed a bug introduced in august 1997 that caused expressions 31585587Sobrien like $f[1] to be syntax errors. thanks to arnold robbins for 31685587Sobrien noticing this and providing a fix. 31785587Sobrien 31885587SobrienOct 30, 2000: 31985587Sobrien fixed some nextfile bugs: not handling all cases. thanks to 32085587Sobrien arnold robbins for pointing this out. new regressions added. 32185587Sobrien 32285587Sobrien close() is now a function. it returns whatever the library 32385587Sobrien fclose returns, and -1 for closing a file or pipe that wasn't 32485587Sobrien opened. 32585587Sobrien 32685587SobrienSep 24, 2000: 32785587Sobrien permit \n explicitly in character classes; won't work right 32885587Sobrien if comes in as "[\n]" but ok as /[\n]/, because of multiple 32985587Sobrien processing of \'s. thanks to arnold robbins. 33085587Sobrien 33185587SobrienJuly 5, 2000: 33285587Sobrien minor fiddles in tran.c to keep compilers happy about uschar. 33385587Sobrien thanks to norman wilson. 33485587Sobrien 33585587SobrienMay 25, 2000: 33685587Sobrien yet another attempt at making 8-bit input work, with another 33785587Sobrien band-aid in b.c (member()), and some (uschar) casts to head 33885587Sobrien off potential errors in subscripts (like isdigit). also 33985587Sobrien changed HAT to NCHARS-2. thanks again to santiago vila. 34085587Sobrien 34185587Sobrien changed maketab.c to ignore apparently out of range definitions 34285587Sobrien instead of halting; new freeBSD generates one. thanks to 34385587Sobrien jon snader <jsnader@ix.netcom.com> for pointing out the problem. 34485587Sobrien 34585587SobrienMay 2, 2000: 34685587Sobrien fixed an 8-bit problem in b.c by making several char*'s into 34785587Sobrien unsigned char*'s. not clear i have them all yet. thanks to 34885587Sobrien Santiago Vila <sanvila@unex.es> for the bug report. 34985587Sobrien 35085587SobrienApr 21, 2000: 35185587Sobrien finally found and fixed a memory leak in function call; it's 35285587Sobrien been there since functions were added ~1983. thanks to 35385587Sobrien jon bentley for the test case that found it. 35485587Sobrien 35585587Sobrien added test in envinit to catch environment "variables" with 356146299Sru names beginning with '='; thanks to Berend Hasselman. 35785587Sobrien 35885587SobrienJul 28, 1999: 35985587Sobrien added test in defn() to catch function foo(foo), which 36085587Sobrien otherwise recurses until core dump. thanks to arnold 36185587Sobrien robbins for noticing this. 36285587Sobrien 36385587SobrienJun 20, 1999: 36485587Sobrien added *bp in gettok in lex.c; appears possible to exit function 36585587Sobrien without terminating the string. thanks to russ cox. 36685587Sobrien 36785587SobrienJun 2, 1999: 36885587Sobrien added function stdinit() to run to initialize files[] array, 36985587Sobrien in case stdin, etc., are not constants; some compilers care. 37085587Sobrien 37185587SobrienMay 10, 1999: 37285587Sobrien replaced the ERROR ... FATAL, etc., macros with functions 37385587Sobrien based on vprintf, to avoid problems caused by overrunning 37485587Sobrien fixed-size errbuf array. thanks to ralph corderoy for the 37585587Sobrien impetus, and for pointing out a string termination bug in 37685587Sobrien qstring as well. 37785587Sobrien 37885587SobrienApr 21, 1999: 37985587Sobrien fixed bug that caused occasional core dumps with commandline 38085587Sobrien variable with value ending in \. (thanks to nelson beebe for 38185587Sobrien the test case.) 38285587Sobrien 38385587SobrienApr 16, 1999: 38485587Sobrien with code kindly provided by Bruce Lilly, awk now parses 38585587Sobrien /=/ and similar constructs more sensibly in more places. 38685587Sobrien Bruce also provided some helpful test cases. 38785587Sobrien 38885587SobrienApr 5, 1999: 38985587Sobrien changed true/false to True/False in run.c to make it 39085587Sobrien easier to compile with C++. Added some casts on malloc 39185587Sobrien and realloc to be honest about casts; ditto. changed 39285587Sobrien ltype int to long in struct rrow to reduce some 64-bit 39385587Sobrien complaints; other changes scattered throughout for the 39485587Sobrien same purpose. thanks to Nelson Beebe for these portability 39585587Sobrien improvements. 39685587Sobrien 39785587Sobrien removed some horrible pointer-int casting in b.c and elsewhere 39885587Sobrien by adding ptoi and itonp to localize the casts, which are 39985587Sobrien all benign. fixed one incipient bug that showed up on sgi 40085587Sobrien in 64-bit mode. 40185587Sobrien 40285587Sobrien reset lineno for new source file; include filename in error 40385587Sobrien message. also fixed line number error in continuation lines. 40485587Sobrien (thanks to Nelson Beebe for both of these.) 40585587Sobrien 40685587SobrienMar 24, 1999: 40785587Sobrien Nelson Beebe notes that irix 5.3 yacc dies with a bogus 40885587Sobrien error; use a newer version or switch to bison, since sgi 40985587Sobrien is unlikely to fix it. 41085587Sobrien 41185587SobrienMar 5, 1999: 41285587Sobrien changed isnumber to is_number to avoid the problem caused by 41385587Sobrien versions of ctype.h that include the name isnumber. 41485587Sobrien 41585587Sobrien distribution now includes a script for building on a Mac, 41685587Sobrien thanks to Dan Allen. 41785587Sobrien 41885587SobrienFeb 20, 1999: 41985587Sobrien fixed memory leaks in run.c (call) and tran.c (setfval). 42085587Sobrien thanks to Stephen Nutt for finding these and providing the fixes. 42185587Sobrien 42285587SobrienJan 13, 1999: 42385587Sobrien replaced srand argument by (unsigned int) in run.c; 42485587Sobrien avoids problem on Mac and potentially on Unix & Windows. 42585587Sobrien thanks to Dan Allen. 42685587Sobrien 42785587Sobrien added a few (int) casts to silence useless compiler warnings. 42885587Sobrien e.g., errorflag= in run.c jump(). 42985587Sobrien 43085587Sobrien added proctab.c to the bundle outout; one less thing 43185587Sobrien to have to compile out of the box. 43285587Sobrien 43385587Sobrien added calls to _popen and _pclose to the win95 stub for 43485587Sobrien pipes (thanks to Steve Adams for this helpful suggestion). 43585587Sobrien seems to work, though properties are not well understood 43685587Sobrien by me, and it appears that under some circumstances the 43785587Sobrien pipe output is truncated. Be careful. 43885587Sobrien 43985587SobrienOct 19, 1998: 44085587Sobrien fixed a couple of bugs in getrec: could fail to update $0 44185587Sobrien after a getline var; because inputFS wasn't initialized, 44285587Sobrien could split $0 on every character, a misleading diversion. 44385587Sobrien 44485587Sobrien fixed caching bug in makedfa: LRU was actually removing 44585587Sobrien least often used. 44685587Sobrien 44785587Sobrien thanks to ross ridge for finding these, and for providing 44885587Sobrien great bug reports. 44985587Sobrien 45085587SobrienMay 12, 1998: 45185587Sobrien fixed potential bug in readrec: might fail to update record 45285587Sobrien pointer after growing. thanks to dan levy for spotting this 45385587Sobrien and suggesting the fix. 45485587Sobrien 45585587SobrienMar 12, 1998: 45685587Sobrien added -V to print version number and die. 45785587Sobrien 45885587SobrienFeb 11, 1998: 45985587Sobrien subtle silent bug in lex.c: if the program ended with a number 46085587Sobrien longer than 1 digit, part of the input would be pushed back and 46185587Sobrien parsed again because token buffer wasn't terminated right. 46285587Sobrien example: awk 'length($0) > 10'. blush. at least i found it 46385587Sobrien myself. 46485587Sobrien 46585587SobrienAug 31, 1997: 46685587Sobrien s/adelete/awkdelete/: SGI uses this in malloc.h. 46785587Sobrien thanks to nelson beebe for pointing this one out. 46885587Sobrien 46985587SobrienAug 21, 1997: 47085587Sobrien fixed some bugs in sub and gsub when replacement includes \\. 47185587Sobrien this is a dark, horrible corner, but at least now i believe that 47285587Sobrien the behavior is the same as gawk and the intended posix standard. 47385587Sobrien thanks to arnold robbins for advice here. 47485587Sobrien 47585587SobrienAug 9, 1997: 47685587Sobrien somewhat regretfully, replaced the ancient lex-based lexical 47785587Sobrien analyzer with one written in C. it's longer, generates less code, 47885587Sobrien and more portable; the old one depended too much on mysterious 47985587Sobrien properties of lex that were not preserved in other environments. 48085587Sobrien in theory these recognize the same language. 48185587Sobrien 48285587Sobrien now using strtod to test whether a string is a number, instead of 48385587Sobrien the convoluted original function. should be more portable and 48485587Sobrien reliable if strtod is implemented right. 48585587Sobrien 48685587Sobrien removed now-pointless optimization in makefile that tries to avoid 48785587Sobrien recompilation when awkgram.y is changed but symbols are not. 48885587Sobrien 48985587Sobrien removed most fixed-size arrays, though a handful remain, some 49085587Sobrien of which are unchecked. you have been warned. 49185587Sobrien 49285587SobrienAug 4, 1997: 49385587Sobrien with some trepidation, replaced the ancient code that managed 49485587Sobrien fields and $0 in fixed-size arrays with arrays that grow on 49585587Sobrien demand. there is still some tension between trying to make this 49685587Sobrien run fast and making it clean; not sure it's right yet. 49785587Sobrien 49885587Sobrien the ill-conceived -mr and -mf arguments are now useful only 49985587Sobrien for debugging. previous dynamic string code removed. 50085587Sobrien 50185587Sobrien numerous other minor cleanups along the way. 50285587Sobrien 50385587SobrienJul 30, 1997: 50485587Sobrien using code provided by dan levy (to whom profuse thanks), replaced 50585587Sobrien fixed-size arrays and awkward kludges by a fairly uniform mechanism 50685587Sobrien to grow arrays as needed for printf, sub, gsub, etc. 50785587Sobrien 50885587SobrienJul 23, 1997: 50985587Sobrien falling off the end of a function returns "" and 0, not 0. 51085587Sobrien thanks to arnold robbins. 51185587Sobrien 51285587SobrienJun 17, 1997: 51385587Sobrien replaced several fixed-size arrays by dynamically-created ones 51485587Sobrien in run.c; added overflow tests to some previously unchecked cases. 51585587Sobrien getline, toupper, tolower. 51685587Sobrien 51785587Sobrien getline code is still broken in that recursive calls may wind 51885587Sobrien up using the same space. [fixed later] 51985587Sobrien 52085587Sobrien increased RECSIZE to 8192 to push problems further over the horizon. 52185587Sobrien 52285587Sobrien added \r to \n as input line separator for programs, not data. 52385587Sobrien damn CRLFs. 52485587Sobrien 52585587Sobrien modified format() to permit explicit printf("%c", 0) to include 52685587Sobrien a null byte in output. thanks to ken stailey for the fix. 52785587Sobrien 52885587Sobrien added a "-safe" argument that disables file output (print >, 52985587Sobrien print >>), process creation (cmd|getline, print |, system), and 53085587Sobrien access to the environment (ENVIRON). this is a first approximation 53185587Sobrien to a "safe" version of awk, but don't rely on it too much. thanks 53285587Sobrien to joan feigenbaum and matt blaze for the inspiration long ago. 53385587Sobrien 53485587SobrienJul 8, 1996: 53585587Sobrien fixed long-standing bug in sub, gsub(/a/, "\\\\&"); thanks to 53685587Sobrien ralph corderoy. 53785587Sobrien 53885587SobrienJun 29, 1996: 53985587Sobrien fixed awful bug in new field splitting; didn't get all the places 54085587Sobrien where input was done. 54185587Sobrien 54285587SobrienJun 28, 1996: 54385587Sobrien changed field-splitting to conform to posix definition: fields are 54485587Sobrien split using the value of FS at the time of input; it used to be 54585587Sobrien the value when the field or NF was first referred to, a much less 54685587Sobrien predictable definition. thanks to arnold robbins for encouragement 54785587Sobrien to do the right thing. 54885587Sobrien 54985587SobrienMay 28, 1996: 55085587Sobrien fixed appalling but apparently unimportant bug in parsing octal 55185587Sobrien numbers in reg exprs. 55285587Sobrien 55385587Sobrien explicit hex in reg exprs now limited to 2 chars: \xa, \xaa. 55485587Sobrien 55585587SobrienMay 27, 1996: 55685587Sobrien cleaned up some declarations so gcc -Wall is now almost silent. 55785587Sobrien 55885587Sobrien makefile now includes backup copies of ytab.c and lexyy.c in case 55985587Sobrien one makes before looking; it also avoids recreating lexyy.c unless 56085587Sobrien really needed. 56185587Sobrien 56285587Sobrien s/aprintf/awkprint, s/asprintf/awksprintf/ to avoid some name clashes 56385587Sobrien with unwisely-written header files. 56485587Sobrien 56585587Sobrien thanks to jeffrey friedl for several of these. 56685587Sobrien 56785587SobrienMay 26, 1996: 56885587Sobrien an attempt to rationalize the (unsigned) char issue. almost all 56985587Sobrien instances of unsigned char have been removed; the handful of places 57085587Sobrien in b.c where chars are used as table indices have been hand-crafted. 57185587Sobrien added some latin-1 tests to the regression, but i'm not confident; 57285587Sobrien none of my compilers seem to care much. thanks to nelson beebe for 57385587Sobrien pointing out some others that do care. 57485587Sobrien 57585587SobrienMay 2, 1996: 57685587Sobrien removed all register declarations. 57785587Sobrien 57885587Sobrien enhanced split(), as in gawk, etc: split(s, a, "") splits s into 57985587Sobrien a[1]...a[length(s)] with each character a single element. 58085587Sobrien 58185587Sobrien made the same changes for field-splitting if FS is "". 58285587Sobrien 58385587Sobrien added nextfile, as in gawk: causes immediate advance to next 58485587Sobrien input file. (thanks to arnold robbins for inspiration and code). 58585587Sobrien 58685587Sobrien small fixes to regexpr code: can now handle []], [[], and 58785587Sobrien variants; [] is now a syntax error, rather than matching 58885587Sobrien everything; [z-a] is now empty, not z. far from complete 58985587Sobrien or correct, however. (thanks to jeffrey friedl for pointing out 59085587Sobrien some awful behaviors.) 59185587Sobrien 59285587SobrienApr 29, 1996: 593146299Sru replaced uchar by uschar everywhere; apparently some compilers 59485587Sobrien usurp this name and this causes conflicts. 59585587Sobrien 59685587Sobrien fixed call to time in run.c (bltin); arg is time_t *. 59785587Sobrien 59885587Sobrien replaced horrible pointer/long punning in b.c by a legitimate 59985587Sobrien union. should be safer on 64-bit machines and cleaner everywhere. 60085587Sobrien (thanks to nelson beebe for pointing out some of these problems.) 60185587Sobrien 60285587Sobrien replaced nested comments by #if 0...#endif in run.c, lib.c. 60385587Sobrien 60485587Sobrien removed getsval, setsval, execute macros from run.c and lib.c. 60585587Sobrien machines are 100x faster than they were when these macros were 60685587Sobrien first used. 60785587Sobrien 60885587Sobrien revised filenames: awk.g.y => awkgram.y, awk.lx.l => awklex.l, 60985587Sobrien y.tab.[ch] => ytab.[ch], lex.yy.c => lexyy.c, all in the aid of 61085587Sobrien portability to nameless systems. 61185587Sobrien 61285587Sobrien "make bundle" now includes yacc and lex output files for recipients 61385587Sobrien who don't have yacc or lex. 61485587Sobrien 61585587SobrienAug 15, 1995: 61685587Sobrien initialized Cells in setsymtab more carefully; some fields 61785587Sobrien were not set. (thanks to purify, all of whose complaints i 61885587Sobrien think i now understand.) 61985587Sobrien 62085587Sobrien fixed at least one error in gsub that looked at -1-th element 62185587Sobrien of an array when substituting for a null match (e.g., $). 62285587Sobrien 62385587Sobrien delete arrayname is now legal; it clears the elements but leaves 62485587Sobrien the array, which may not be the right behavior. 62585587Sobrien 62685587Sobrien modified makefile: my current make can't cope with the test used 62785587Sobrien to avoid unnecessary yacc invocations. 62885587Sobrien 62985587SobrienJul 17, 1995: 63085587Sobrien added dynamically growing strings to awk.lx.l and b.c 63185587Sobrien to permit regular expressions to be much bigger. 63285587Sobrien the state arrays can still overflow. 63385587Sobrien 63485587SobrienAug 24, 1994: 63585587Sobrien detect duplicate arguments in function definitions (mdm). 63685587Sobrien 63785587SobrienMay 11, 1994: 63885587Sobrien trivial fix to printf to limit string size in sub(). 63985587Sobrien 64085587SobrienApr 22, 1994: 64185587Sobrien fixed yet another subtle self-assignment problem: 64285587Sobrien $1 = $2; $1 = $1 clobbered $1. 64385587Sobrien 64485587Sobrien Regression tests now use private echo, to avoid quoting problems. 64585587Sobrien 64685587SobrienFeb 2, 1994: 64785587Sobrien changed error() to print line number as %d, not %g. 64885587Sobrien 64985587SobrienJul 23, 1993: 65085587Sobrien cosmetic changes: increased sizes of some arrays, 65185587Sobrien reworded some error messages. 65285587Sobrien 65385587Sobrien added CONVFMT as in posix (just replaced OFMT in getsval) 65485587Sobrien 65585587Sobrien FILENAME is now "" until the first thing that causes a file 65685587Sobrien to be opened. 65785587Sobrien 65885587SobrienNov 28, 1992: 65985587Sobrien deleted yyunput and yyoutput from proto.h; 66085587Sobrien different versions of lex give these different declarations. 66185587Sobrien 66285587SobrienMay 31, 1992: 66385587Sobrien added -mr N and -mf N options: more record and fields. 66485587Sobrien these really ought to adjust automatically. 66585587Sobrien 66685587Sobrien cleaned up some error messages; "out of space" now means 66785587Sobrien malloc returned NULL in all cases. 66885587Sobrien 66985587Sobrien changed rehash so that if it runs out, it just returns; 67085587Sobrien things will continue to run slow, but maybe a bit longer. 67185587Sobrien 67285587SobrienApr 24, 1992: 67385587Sobrien remove redundant close of stdin when using -f -. 67485587Sobrien 67585587Sobrien got rid of core dump with -d; awk -d just prints date. 67685587Sobrien 67785587SobrienApr 12, 1992: 67885587Sobrien added explicit check for /dev/std(in,out,err) in redirection. 67985587Sobrien unlike gawk, no /dev/fd/n yet. 68085587Sobrien 68185587Sobrien added (file/pipe) builtin. hard to test satisfactorily. 68285587Sobrien not posix. 68385587Sobrien 68485587SobrienFeb 20, 1992: 68585587Sobrien recompile after abortive changes; should be unchanged. 68685587Sobrien 68785587SobrienDec 2, 1991: 68885587Sobrien die-casting time: converted to ansi C, installed that. 68985587Sobrien 69085587SobrienNov 30, 1991: 69185587Sobrien fixed storage leak in freefa, failing to recover [N]CCL. 69285587Sobrien thanks to Bill Jones (jones@cs.usask.ca) 69385587Sobrien 69485587SobrienNov 19, 1991: 69585587Sobrien use RAND_MAX instead of literal in builtin(). 69685587Sobrien 69785587SobrienNov 12, 1991: 69885587Sobrien cranked up some fixed-size arrays in b.c, and added a test for 69985587Sobrien overflow in penter. thanks to mark larsen. 70085587Sobrien 70185587SobrienSep 24, 1991: 70285587Sobrien increased buffer in gsub. a very crude fix to a general problem. 70385587Sobrien and again on Sep 26. 70485587Sobrien 70585587SobrienAug 18, 1991: 70685587Sobrien enforce variable name syntax for commandline variables: has to 70785587Sobrien start with letter or _. 70885587Sobrien 70985587SobrienJul 27, 1991: 71085587Sobrien allow newline after ; in for statements. 71185587Sobrien 71285587SobrienJul 21, 1991: 71385587Sobrien fixed so that in self-assignment like $1=$1, side effects 71485587Sobrien like recomputing $0 take place. (this is getting subtle.) 71585587Sobrien 71685587SobrienJun 30, 1991: 71785587Sobrien better test for detecting too-long output record. 71885587Sobrien 71985587SobrienJun 2, 1991: 72085587Sobrien better defense against very long printf strings. 72185587Sobrien made break and continue illegal outside of loops. 72285587Sobrien 72385587SobrienMay 13, 1991: 72485587Sobrien removed extra arg on gettemp, tempfree. minor error message rewording. 72585587Sobrien 72685587SobrienMay 6, 1991: 72785587Sobrien fixed silly bug in hex parsing in hexstr(). 72885587Sobrien removed an apparently unnecessary test in isnumber(). 72985587Sobrien warn about weird printf conversions. 73085587Sobrien fixed unchecked array overwrite in relex(). 73185587Sobrien 73285587Sobrien changed for (i in array) to access elements in sorted order. 73385587Sobrien then unchanged it -- it really does run slower in too many cases. 73485587Sobrien left the code in place, commented out. 73585587Sobrien 73685587SobrienFeb 10, 1991: 73785587Sobrien check error status on all writes, to avoid banging on full disks. 73885587Sobrien 73985587SobrienJan 28, 1991: 74085587Sobrien awk -f - reads the program from stdin. 74185587Sobrien 74285587SobrienJan 11, 1991: 74385587Sobrien failed to set numeric state on $0 in cmd|getline context in run.c. 74485587Sobrien 74585587SobrienNov 2, 1990: 74685587Sobrien fixed sleazy test for integrality in getsval; use modf. 74785587Sobrien 74885587SobrienOct 29, 1990: 74985587Sobrien fixed sleazy buggy code in lib.c that looked (incorrectly) for 75085587Sobrien too long input lines. 75185587Sobrien 75285587SobrienOct 14, 1990: 75385587Sobrien fixed the bug on p. 198 in which it couldn't deduce that an 75485587Sobrien argument was an array in some contexts. replaced the error 75585587Sobrien message in intest() by code that damn well makes it an array. 75685587Sobrien 75785587SobrienOct 8, 1990: 75885587Sobrien fixed horrible bug: types and values were not preserved in 75985587Sobrien some kinds of self-assignment. (in assign().) 76085587Sobrien 76185587SobrienAug 24, 1990: 76285587Sobrien changed NCHARS to 256 to handle 8-bit characters in strings 76385587Sobrien presented to match(), etc. 76485587Sobrien 76585587SobrienJun 26, 1990: 76685587Sobrien changed struct rrow (awk.h) to use long instead of int for lval, 76785587Sobrien since cfoll() stores a pointer in it. now works better when int's 76885587Sobrien are smaller than pointers! 76985587Sobrien 77085587SobrienMay 6, 1990: 77185587Sobrien AVA fixed the grammar so that ! is uniformly of the same precedence as 77285587Sobrien unary + and -. This renders illegal some constructs like !x=y, which 77385587Sobrien now has to be parenthesized as !(x=y), and makes others work properly: 77485587Sobrien !x+y is (!x)+y, and x!y is x !y, not two pattern-action statements. 77585587Sobrien (These problems were pointed out by Bob Lenk of Posix.) 77685587Sobrien 77785587Sobrien Added \x to regular expressions (already in strings). 77885587Sobrien Limited octal to octal digits; \8 and \9 are not octal. 77985587Sobrien Centralized the code for parsing escapes in regular expressions. 78085587Sobrien Added a bunch of tests to T.re and T.sub to verify some of this. 78185587Sobrien 78285587SobrienFeb 9, 1990: 78385587Sobrien fixed null pointer dereference bug in main.c: -F[nothing]. sigh. 78485587Sobrien 78585587Sobrien restored srand behavior: it returns the current seed. 78685587Sobrien 78785587SobrienJan 18, 1990: 78885587Sobrien srand now returns previous seed value (0 to start). 78985587Sobrien 79085587SobrienJan 5, 1990: 79185587Sobrien fix potential problem in tran.c -- something was freed, 79285587Sobrien then used in freesymtab. 79385587Sobrien 79485587SobrienOct 18, 1989: 79585587Sobrien another try to get the max number of open files set with 79685587Sobrien relatively machine-independent code. 79785587Sobrien 79885587Sobrien small fix to input() in case of multiple reads after EOF. 79985587Sobrien 80085587SobrienOct 11, 1989: 80185587Sobrien FILENAME is now defined in the BEGIN block -- too many old 80285587Sobrien programs broke. 80385587Sobrien 80485587Sobrien "-" means stdin in getline as well as on the commandline. 80585587Sobrien 80685587Sobrien added a bunch of casts to the code to tell the truth about 80785587Sobrien char * vs. unsigned char *, a right royal pain. added a 80885587Sobrien setlocale call to the front of main, though probably no one 80985587Sobrien has it usefully implemented yet. 81085587Sobrien 81185587SobrienAug 24, 1989: 81285587Sobrien removed redundant relational tests against nullnode if parse 81385587Sobrien tree already had a relational at that point. 81485587Sobrien 81585587SobrienAug 11, 1989: 81685587Sobrien fixed bug: commandline variable assignment has to look like 81785587Sobrien var=something. (consider the man page for =, in file =.1) 81885587Sobrien 81985587Sobrien changed number of arguments to functions to static arrays 82085587Sobrien to avoid repeated malloc calls. 82185587Sobrien 82285587SobrienAug 2, 1989: 82385587Sobrien restored -F (space) separator 82485587Sobrien 82585587SobrienJul 30, 1989: 82685587Sobrien added -v x=1 y=2 ... for immediate commandline variable assignment; 82785587Sobrien done before the BEGIN block for sure. they have to precede the 82885587Sobrien program if the program is on the commandline. 82985587Sobrien Modified Aug 2 to require a separate -v for each assignment. 83085587Sobrien 83185587SobrienJul 10, 1989: 83285587Sobrien fixed ref-thru-zero bug in environment code in tran.c 83385587Sobrien 83485587SobrienJun 23, 1989: 83585587Sobrien add newline to usage message. 83685587Sobrien 83785587SobrienJun 14, 1989: 83885587Sobrien added some missing ansi printf conversion letters: %i %X %E %G. 83985587Sobrien no sensible meaning for h or L, so they may not do what one expects. 84085587Sobrien 84185587Sobrien made %* conversions work. 84285587Sobrien 84385587Sobrien changed x^y so that if n is a positive integer, it's done 84485587Sobrien by explicit multiplication, thus achieving maximum accuracy. 84585587Sobrien (this should be done by pow() but it seems not to be locally.) 84685587Sobrien done to x ^= y as well. 84785587Sobrien 84885587SobrienJun 4, 1989: 84985587Sobrien ENVIRON array contains environment: if shell variable V=thing, 85085587Sobrien ENVIRON["V"] is "thing" 85185587Sobrien 85285587Sobrien multiple -f arguments permitted. error reporting is naive. 85385587Sobrien (they were permitted before, but only the last was used.) 85485587Sobrien 85585587Sobrien fixed a really stupid botch in the debugging macro dprintf 85685587Sobrien 85785587Sobrien fixed order of evaluation of commandline assignments to match 85885587Sobrien what the book claims: an argument of the form x=e is evaluated 85985587Sobrien at the time it would have been opened if it were a filename (p 63). 86085587Sobrien this invalidates the suggested answer to ex 4-1 (p 195). 86185587Sobrien 86285587Sobrien removed some code that permitted -F (space) fieldseparator, 86385587Sobrien since it didn't quite work right anyway. (restored aug 2) 86485587Sobrien 86585587SobrienApr 27, 1989: 86685587Sobrien Line number now accumulated correctly for comment lines. 86785587Sobrien 86885587SobrienApr 26, 1989: 86985587Sobrien Debugging output now includes a version date, 87085587Sobrien if one compiles it into the source each time. 87185587Sobrien 87285587SobrienApr 9, 1989: 87385587Sobrien Changed grammar to prohibit constants as 3rd arg of sub and gsub; 87485587Sobrien prevents class of overwriting-a-constant errors. (Last one?) 87585587Sobrien This invalidates the "banana" example on page 43 of the book. 87685587Sobrien 87785587Sobrien Added \a ("alert"), \v (vertical tab), \xhhh (hexadecimal), 87885587Sobrien as in ANSI, for strings. Rescinded the sloppiness that permitted 87985587Sobrien non-octal digits in \ooo. Warning: not all compilers and libraries 88085587Sobrien will be able to deal with \x correctly. 88185587Sobrien 88285587SobrienJan 9, 1989: 88385587Sobrien Fixed bug that caused tempcell list to contain a duplicate. 88485587Sobrien The fix is kludgy. 88585587Sobrien 88685587SobrienDec 17, 1988: 88785587Sobrien Catches some more commandline errors in main. 88885587Sobrien Removed redundant decl of modf in run.c (confuses some compilers). 88985587Sobrien Warning: there's no single declaration of malloc, etc., in awk.h 89085587Sobrien that seems to satisfy all compilers. 89185587Sobrien 89285587SobrienDec 7, 1988: 89385587Sobrien Added a bit of code to error printing to avoid printing nulls. 89485587Sobrien (Not clear that it actually would.) 89585587Sobrien 89685587SobrienNov 27, 1988: 89785587Sobrien With fear and trembling, modified the grammar to permit 89885587Sobrien multiple pattern-action statements on one line without 89985587Sobrien an explicit separator. By definition, this capitulation 90085587Sobrien to the ghost of ancient implementations remains undefined 90185587Sobrien and thus subject to change without notice or apology. 90285587Sobrien DO NOT COUNT ON IT. 90385587Sobrien 90485587SobrienOct 30, 1988: 90585587Sobrien Fixed bug in call() that failed to recover storage. 90685587Sobrien 90785587Sobrien A warning is now generated if there are more arguments 90885587Sobrien in the call than in the definition (in lieu of fixing 90985587Sobrien another storage leak). 91085587Sobrien 91185587SobrienOct 20, 1988: 91285587Sobrien Fixed %c: if expr is numeric, use numeric value; 91385587Sobrien otherwise print 1st char of string value. still 91485587Sobrien doesn't work if the value is 0 -- won't print \0. 91585587Sobrien 91685587Sobrien Added a few more checks for running out of malloc. 91785587Sobrien 91885587SobrienOct 12, 1988: 91985587Sobrien Fixed bug in call() that freed local arrays twice. 92085587Sobrien 92185587Sobrien Fixed to handle deletion of non-existent array right; 92285587Sobrien complains about attempt to delete non-array element. 92385587Sobrien 92485587SobrienSep 30, 1988: 92585587Sobrien Now guarantees to evaluate all arguments of built-in 92685587Sobrien functions, as in C; the appearance is that arguments 92785587Sobrien are evaluated before the function is called. Places 92885587Sobrien affected are sub (gsub was ok), substr, printf, and 92985587Sobrien all the built-in arithmetic functions in bltin(). 93085587Sobrien A warning is generated if a bltin() is called with 93185587Sobrien the wrong number of arguments. 93285587Sobrien 93385587Sobrien This requires changing makeprof on p167 of the book. 93485587Sobrien 93585587SobrienAug 23, 1988: 93685587Sobrien setting FILENAME in BEGIN caused core dump, apparently 93785587Sobrien because it was freeing space not allocated by malloc. 93885587Sobrien 93985587SobrienJuly 24, 1988: 94085587Sobrien fixed egregious error in toupper/tolower functions. 94185587Sobrien still subject to rescinding, however. 94285587Sobrien 94385587SobrienJuly 2, 1988: 94485587Sobrien flush stdout before opening file or pipe 94585587Sobrien 94685587SobrienJuly 2, 1988: 94785587Sobrien performance bug in b.c/cgoto(): not freeing some sets of states. 94885587Sobrien partial fix only right now, and the number of states increased 94985587Sobrien to make it less obvious. 95085587Sobrien 95185587SobrienJune 1, 1988: 95285587Sobrien check error status on close 95385587Sobrien 95485587SobrienMay 28, 1988: 95585587Sobrien srand returns seed value it's using. 95685587Sobrien see 1/18/90 95785587Sobrien 95885587SobrienMay 22, 1988: 95985587Sobrien Removed limit on depth of function calls. 96085587Sobrien 96185587SobrienMay 10, 1988: 96285587Sobrien Fixed lib.c to permit _ in commandline variable names. 96385587Sobrien 96485587SobrienMar 25, 1988: 96585587Sobrien main.c fixed to recognize -- as terminator of command- 96685587Sobrien line options. Illegal options flagged. 96785587Sobrien Error reporting slightly cleaned up. 96885587Sobrien 96985587SobrienDec 2, 1987: 97085587Sobrien Newer C compilers apply a strict scope rule to extern 97185587Sobrien declarations within functions. Two extern declarations in 97285587Sobrien lib.c and tran.c have been moved to obviate this problem. 97385587Sobrien 97485587SobrienOct xx, 1987: 97585587Sobrien Reluctantly added toupper and tolower functions. 97685587Sobrien Subject to rescinding without notice. 97785587Sobrien 97885587SobrienSep 17, 1987: 97985587Sobrien Error-message printer had printf(s) instead of 98085587Sobrien printf("%s",s); got core dumps when the message 98185587Sobrien included a %. 98285587Sobrien 98385587SobrienSep 12, 1987: 98485587Sobrien Very long printf strings caused core dump; 98585587Sobrien fixed aprintf, asprintf, format to catch them. 98685587Sobrien Can still get a core dump in printf itself. 98785587Sobrien 98885587Sobrien 989
