-
-This file lists all bug fixes, changes, etc., made since the AWK book
-was sent to the printers in August, 1987.
-
-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) 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> 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) for pointing this out.
-
- GNU compatibility: an empty regexp matches anything (thanks to
- dag-erling smorgrav, des@ofug.org). 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
-
- 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.
-
-Oct 30, 2000:
- fixed some nextfile bugs: not handling all cases. thanks to
- arnold robbins for pointing this out. new regressions added.
-
- close() is now a function. it returns whatever the library
- fclose returns, and -1 for closing a file or pipe that wasn't
- opened.
-
-Sep 24, 2000:
- permit \n explicitly in character classes; won't work right
- if comes in as "[\n]" but ok as /[\n]/, because of multiple
- processing of \'s. thanks to arnold robbins.
-
-July 5, 2000:
- minor fiddles in tran.c to keep compilers happy about uschar.
- thanks to norman wilson.
-
-May 25, 2000:
- yet another attempt at making 8-bit input work, with another
- band-aid in b.c (member()), and some (uschar) casts to head
- off potential errors in subscripts (like isdigit). also
- changed HAT to NCHARS-2. thanks again to santiago vila.
-
- changed maketab.c to ignore apparently out of range definitions
- instead of halting; new freeBSD generates one. thanks to
- jon snader <jsnader@ix.netcom.com> for pointing out the problem.
-
-May 2, 2000:
- fixed an 8-bit problem in b.c by making several char*'s into
- unsigned char*'s. not clear i have them all yet. thanks to
- Santiago Vila <sanvila@unex.es> for the bug report.
-
-Apr 21, 2000:
- finally found and fixed a memory leak in function call; it's
- been there since functions were added ~1983. thanks to
- jon bentley for the test case that found it.
-
- added test in envinit to catch environment "variables" with
- names beginning with '='; thanks to Berend Hasselman.
-
-Jul 28, 1999:
- added test in defn() to catch function foo(foo), which
- otherwise recurses until core dump. thanks to arnold
- robbins for noticing this.
-
-Jun 20, 1999:
- added *bp in gettok in lex.c; appears possible to exit function
- without terminating the string. thanks to russ cox.
-
-Jun 2, 1999:
- added function stdinit() to run to initialize files[] array,
- in case stdin, etc., are not constants; some compilers care.
-
-May 10, 1999:
- replaced the ERROR ... FATAL, etc., macros with functions
- based on vprintf, to avoid problems caused by overrunning
- fixed-size errbuf array. thanks to ralph corderoy for the
- impetus, and for pointing out a string termination bug in
- qstring as well.
-
-Apr 21, 1999:
- fixed bug that caused occasional core dumps with commandline
- variable with value ending in \. (thanks to nelson beebe for
- the test case.)
-
-Apr 16, 1999:
- with code kindly provided by Bruce Lilly, awk now parses
- /=/ and similar constructs more sensibly in more places.
- Bruce also provided some helpful test cases.
-
-Apr 5, 1999:
- changed true/false to True/False in run.c to make it
- easier to compile with C++. Added some casts on malloc
- and realloc to be honest about casts; ditto. changed
- ltype int to long in struct rrow to reduce some 64-bit
- complaints; other changes scattered throughout for the
- same purpose. thanks to Nelson Beebe for these portability
- improvements.
-
- removed some horrible pointer-int casting in b.c and elsewhere
- by adding ptoi and itonp to localize the casts, which are
- all benign. fixed one incipient bug that showed up on sgi
- in 64-bit mode.
-
- reset lineno for new source file; include filename in error
- message. also fixed line number error in continuation lines.
- (thanks to Nelson Beebe for both of these.)
-
-Mar 24, 1999:
- Nelson Beebe notes that irix 5.3 yacc dies with a bogus
- error; use a newer version or switch to bison, since sgi
- is unlikely to fix it.
-
-Mar 5, 1999:
- changed isnumber to is_number to avoid the problem caused by
- versions of ctype.h that include the name isnumber.
-
- distribution now includes a script for building on a Mac,
- thanks to Dan Allen.
-
-Feb 20, 1999:
- fixed memory leaks in run.c (call) and tran.c (setfval).
- thanks to Stephen Nutt for finding these and providing the fixes.
-
-Jan 13, 1999:
- replaced srand argument by (unsigned int) in run.c;
- avoids problem on Mac and potentially on Unix & Windows.
- thanks to Dan Allen.
-
- added a few (int) casts to silence useless compiler warnings.
- e.g., errorflag= in run.c jump().
-
- added proctab.c to the bundle outout; one less thing
- to have to compile out of the box.
-
- added calls to _popen and _pclose to the win95 stub for
- pipes (thanks to Steve Adams for this helpful suggestion).
- seems to work, though properties are not well understood
- by me, and it appears that under some circumstances the
- pipe output is truncated. Be careful.
-
-Oct 19, 1998:
- fixed a couple of bugs in getrec: could fail to update $0
- after a getline var; because inputFS wasn't initialized,
- could split $0 on every character, a misleading diversion.
-
- fixed caching bug in makedfa: LRU was actually removing
- least often used.
-
- thanks to ross ridge for finding these, and for providing
- great bug reports.
-
-May 12, 1998:
- fixed potential bug in readrec: might fail to update record
- pointer after growing. thanks to dan levy for spotting this
- and suggesting the fix.
-
-Mar 12, 1998:
- added -V to print version number and die.
-
-Feb 11, 1998:
- subtle silent bug in lex.c: if the program ended with a number
- longer than 1 digit, part of the input would be pushed back and
- parsed again because token buffer wasn't terminated right.
- example: awk 'length($0) > 10'. blush. at least i found it
- myself.
-
-Aug 31, 1997:
- s/adelete/awkdelete/: SGI uses this in malloc.h.
- thanks to nelson beebe for pointing this one out.
-
-Aug 21, 1997:
- fixed some bugs in sub and gsub when replacement includes \\.
- this is a dark, horrible corner, but at least now i believe that
- the behavior is the same as gawk and the intended posix standard.
- thanks to arnold robbins for advice here.
-
-Aug 9, 1997:
- somewhat regretfully, replaced the ancient lex-based lexical
- analyzer with one written in C. it's longer, generates less code,
- and more portable; the old one depended too much on mysterious
- properties of lex that were not preserved in other environments.
- in theory these recognize the same language.
-
- now using strtod to test whether a string is a number, instead of
- the convoluted original function. should be more portable and
- reliable if strtod is implemented right.
-
- removed now-pointless optimization in makefile that tries to avoid
- recompilation when awkgram.y is changed but symbols are not.
-
- removed most fixed-size arrays, though a handful remain, some
- of which are unchecked. you have been warned.
-
-Aug 4, 1997:
- with some trepidation, replaced the ancient code that managed
- fields and $0 in fixed-size arrays with arrays that grow on
- demand. there is still some tension between trying to make this
- run fast and making it clean; not sure it's right yet.
-
- the ill-conceived -mr and -mf arguments are now useful only
- for debugging. previous dynamic string code removed.
-
- numerous other minor cleanups along the way.
-
-Jul 30, 1997:
- using code provided by dan levy (to whom profuse thanks), replaced
- fixed-size arrays and awkward kludges by a fairly uniform mechanism
- to grow arrays as needed for printf, sub, gsub, etc.
-
-Jul 23, 1997:
- falling off the end of a function returns "" and 0, not 0.
- thanks to arnold robbins.
-
-Jun 17, 1997:
- replaced several fixed-size arrays by dynamically-created ones
- in run.c; added overflow tests to some previously unchecked cases.
- getline, toupper, tolower.
-
- getline code is still broken in that recursive calls may wind
- up using the same space. [fixed later]
-
- increased RECSIZE to 8192 to push problems further over the horizon.
-
- added \r to \n as input line separator for programs, not data.
- damn CRLFs.
-
- modified format() to permit explicit printf("%c", 0) to include
- a null byte in output. thanks to ken stailey for the fix.
-
- added a "-safe" argument that disables file output (print >,
- print >>), process creation (cmd|getline, print |, system), and
- access to the environment (ENVIRON). this is a first approximation
- to a "safe" version of awk, but don't rely on it too much. thanks
- to joan feigenbaum and matt blaze for the inspiration long ago.
-
-Jul 8, 1996:
- fixed long-standing bug in sub, gsub(/a/, "\\\\&"); thanks to
- ralph corderoy.
-
-Jun 29, 1996:
- fixed awful bug in new field splitting; didn't get all the places
- where input was done.
-
-Jun 28, 1996:
- changed field-splitting to conform to posix definition: fields are
- split using the value of FS at the time of input; it used to be
- the value when the field or NF was first referred to, a much less
- predictable definition. thanks to arnold robbins for encouragement
- to do the right thing.
-
-May 28, 1996:
- fixed appalling but apparently unimportant bug in parsing octal
- numbers in reg exprs.
-
- explicit hex in reg exprs now limited to 2 chars: \xa, \xaa.
-
-May 27, 1996:
- cleaned up some declarations so gcc -Wall is now almost silent.
-
- makefile now includes backup copies of ytab.c and lexyy.c in case
- one makes before looking; it also avoids recreating lexyy.c unless
- really needed.
-
- s/aprintf/awkprint, s/asprintf/awksprintf/ to avoid some name clashes
- with unwisely-written header files.
-
- thanks to jeffrey friedl for several of these.
-
-May 26, 1996:
- an attempt to rationalize the (unsigned) char issue. almost all
- instances of unsigned char have been removed; the handful of places
- in b.c where chars are used as table indices have been hand-crafted.
- added some latin-1 tests to the regression, but i'm not confident;
- none of my compilers seem to care much. thanks to nelson beebe for
- pointing out some others that do care.
-
-May 2, 1996:
- removed all register declarations.
-
- enhanced split(), as in gawk, etc: split(s, a, "") splits s into
- a[1]...a[length(s)] with each character a single element.
-
- made the same changes for field-splitting if FS is "".
-
- added nextfile, as in gawk: causes immediate advance to next
- input file. (thanks to arnold robbins for inspiration and code).
-
- small fixes to regexpr code: can now handle []], [[], and
- variants; [] is now a syntax error, rather than matching
- everything; [z-a] is now empty, not z. far from complete
- or correct, however. (thanks to jeffrey friedl for pointing out
- some awful behaviors.)
-
-Apr 29, 1996:
- replaced uchar by uschar everywhere; apparently some compilers
- usurp this name and this causes conflicts.
-
- fixed call to time in run.c (bltin); arg is time_t *.
-
- replaced horrible pointer/long punning in b.c by a legitimate
- union. should be safer on 64-bit machines and cleaner everywhere.
- (thanks to nelson beebe for pointing out some of these problems.)
-
- replaced nested comments by #if 0...#endif in run.c, lib.c.
-
- removed getsval, setsval, execute macros from run.c and lib.c.
- machines are 100x faster than they were when these macros were
- first used.
-
- revised filenames: awk.g.y => awkgram.y, awk.lx.l => awklex.l,
- y.tab.[ch] => ytab.[ch], lex.yy.c => lexyy.c, all in the aid of
- portability to nameless systems.
-
- "make bundle" now includes yacc and lex output files for recipients
- who don't have yacc or lex.
-
-Aug 15, 1995:
- initialized Cells in setsymtab more carefully; some fields
- were not set. (thanks to purify, all of whose complaints i
- think i now understand.)
-
- fixed at least one error in gsub that looked at -1-th element
- of an array when substituting for a null match (e.g., $).
-
- delete arrayname is now legal; it clears the elements but leaves
- the array, which may not be the right behavior.
-
- modified makefile: my current make can't cope with the test used
- to avoid unnecessary yacc invocations.
-
-Jul 17, 1995:
- added dynamically growing strings to awk.lx.l and b.c
- to permit regular expressions to be much bigger.
- the state arrays can still overflow.
-
-Aug 24, 1994:
- detect duplicate arguments in function definitions (mdm).
-
-May 11, 1994:
- trivial fix to printf to limit string size in sub().
-
-Apr 22, 1994:
- fixed yet another subtle self-assignment problem:
- $1 = $2; $1 = $1 clobbered $1.
-
- Regression tests now use private echo, to avoid quoting problems.
-
-Feb 2, 1994:
- changed error() to print line number as %d, not %g.
-
-Jul 23, 1993:
- cosmetic changes: increased sizes of some arrays,
- reworded some error messages.
-
- added CONVFMT as in posix (just replaced OFMT in getsval)
-
- FILENAME is now "" until the first thing that causes a file
- to be opened.
-
-Nov 28, 1992:
- deleted yyunput and yyoutput from proto.h;
- different versions of lex give these different declarations.
-
-May 31, 1992:
- added -mr N and -mf N options: more record and fields.
- these really ought to adjust automatically.
-
- cleaned up some error messages; "out of space" now means
- malloc returned NULL in all cases.
-
- changed rehash so that if it runs out, it just returns;
- things will continue to run slow, but maybe a bit longer.
-
-Apr 24, 1992:
- remove redundant close of stdin when using -f -.
-
- got rid of core dump with -d; awk -d just prints date.
-
-Apr 12, 1992:
- added explicit check for /dev/std(in,out,err) in redirection.
- unlike gawk, no /dev/fd/n yet.
-
- added (file/pipe) builtin. hard to test satisfactorily.
- not posix.
-
-Feb 20, 1992:
- recompile after abortive changes; should be unchanged.
-
-Dec 2, 1991:
- die-casting time: converted to ansi C, installed that.
-
-Nov 30, 1991:
- fixed storage leak in freefa, failing to recover [N]CCL.
- thanks to Bill Jones (jones@cs.usask.ca)
-
-Nov 19, 1991:
- use RAND_MAX instead of literal in builtin().
-
-Nov 12, 1991:
- cranked up some fixed-size arrays in b.c, and added a test for
- overflow in penter. thanks to mark larsen.
-
-Sep 24, 1991:
- increased buffer in gsub. a very crude fix to a general problem.
- and again on Sep 26.
-
-Aug 18, 1991:
- enforce variable name syntax for commandline variables: has to
- start with letter or _.
-
-Jul 27, 1991:
- allow newline after ; in for statements.
-
-Jul 21, 1991:
- fixed so that in self-assignment like $1=$1, side effects
- like recomputing $0 take place. (this is getting subtle.)
-
-Jun 30, 1991:
- better test for detecting too-long output record.
-
-Jun 2, 1991:
- better defense against very long printf strings.
- made break and continue illegal outside of loops.
-
-May 13, 1991:
- removed extra arg on gettemp, tempfree. minor error message rewording.
-
-May 6, 1991:
- fixed silly bug in hex parsing in hexstr().
- removed an apparently unnecessary test in isnumber().
- warn about weird printf conversions.
- fixed unchecked array overwrite in relex().
-
- changed for (i in array) to access elements in sorted order.
- then unchanged it -- it really does run slower in too many cases.
- left the code in place, commented out.
-
-Feb 10, 1991:
- check error status on all writes, to avoid banging on full disks.
-
-Jan 28, 1991:
- awk -f - reads the program from stdin.
-
-Jan 11, 1991:
- failed to set numeric state on $0 in cmd|getline context in run.c.
-
-Nov 2, 1990:
- fixed sleazy test for integrality in getsval; use modf.
-
-Oct 29, 1990:
- fixed sleazy buggy code in lib.c that looked (incorrectly) for
- too long input lines.
-
-Oct 14, 1990:
- fixed the bug on p. 198 in which it couldn't deduce that an
- argument was an array in some contexts. replaced the error
- message in intest() by code that damn well makes it an array.
-
-Oct 8, 1990:
- fixed horrible bug: types and values were not preserved in
- some kinds of self-assignment. (in assign().)
-
-Aug 24, 1990:
- changed NCHARS to 256 to handle 8-bit characters in strings
- presented to match(), etc.
-
-Jun 26, 1990:
- changed struct rrow (awk.h) to use long instead of int for lval,
- since cfoll() stores a pointer in it. now works better when int's
- are smaller than pointers!
-
-May 6, 1990:
- AVA fixed the grammar so that ! is uniformly of the same precedence as
- unary + and -. This renders illegal some constructs like !x=y, which
- now has to be parenthesized as !(x=y), and makes others work properly:
- !x+y is (!x)+y, and x!y is x !y, not two pattern-action statements.
- (These problems were pointed out by Bob Lenk of Posix.)
-
- Added \x to regular expressions (already in strings).
- Limited octal to octal digits; \8 and \9 are not octal.
- Centralized the code for parsing escapes in regular expressions.
- Added a bunch of tests to T.re and T.sub to verify some of this.
-
-Feb 9, 1990:
- fixed null pointer dereference bug in main.c: -F[nothing]. sigh.
-
- restored srand behavior: it returns the current seed.
-
-Jan 18, 1990:
- srand now returns previous seed value (0 to start).
-
-Jan 5, 1990:
- fix potential problem in tran.c -- something was freed,
- then used in freesymtab.
-
-Oct 18, 1989:
- another try to get the max number of open files set with
- relatively machine-independent code.
-
- small fix to input() in case of multiple reads after EOF.
-
-Oct 11, 1989:
- FILENAME is now defined in the BEGIN block -- too many old
- programs broke.
-
- "-" means stdin in getline as well as on the commandline.
-
- added a bunch of casts to the code to tell the truth about
- char * vs. unsigned char *, a right royal pain. added a
- setlocale call to the front of main, though probably no one
- has it usefully implemented yet.
-
-Aug 24, 1989:
- removed redundant relational tests against nullnode if parse
- tree already had a relational at that point.
-
-Aug 11, 1989:
- fixed bug: commandline variable assignment has to look like
- var=something. (consider the man page for =, in file =.1)
-
- changed number of arguments to functions to static arrays
- to avoid repeated malloc calls.
-
-Aug 2, 1989:
- restored -F (space) separator
-
-Jul 30, 1989:
- added -v x=1 y=2 ... for immediate commandline variable assignment;
- done before the BEGIN block for sure. they have to precede the
- program if the program is on the commandline.
- Modified Aug 2 to require a separate -v for each assignment.
-
-Jul 10, 1989:
- fixed ref-thru-zero bug in environment code in tran.c
-
-Jun 23, 1989:
- add newline to usage message.
-
-Jun 14, 1989:
- added some missing ansi printf conversion letters: %i %X %E %G.
- no sensible meaning for h or L, so they may not do what one expects.
-
- made %* conversions work.
-
- changed x^y so that if n is a positive integer, it's done
- by explicit multiplication, thus achieving maximum accuracy.
- (this should be done by pow() but it seems not to be locally.)
- done to x ^= y as well.
-
-Jun 4, 1989:
- ENVIRON array contains environment: if shell variable V=thing,
- ENVIRON["V"] is "thing"
-
- multiple -f arguments permitted. error reporting is naive.
- (they were permitted before, but only the last was used.)
-
- fixed a really stupid botch in the debugging macro dprintf
-
- fixed order of evaluation of commandline assignments to match
- what the book claims: an argument of the form x=e is evaluated
- at the time it would have been opened if it were a filename (p 63).
- this invalidates the suggested answer to ex 4-1 (p 195).
-
- removed some code that permitted -F (space) fieldseparator,
- since it didn't quite work right anyway. (restored aug 2)
-
-Apr 27, 1989:
- Line number now accumulated correctly for comment lines.
-
-Apr 26, 1989:
- Debugging output now includes a version date,
- if one compiles it into the source each time.
-
-Apr 9, 1989:
- Changed grammar to prohibit constants as 3rd arg of sub and gsub;
- prevents class of overwriting-a-constant errors. (Last one?)
- This invalidates the "banana" example on page 43 of the book.
-
- Added \a ("alert"), \v (vertical tab), \xhhh (hexadecimal),
- as in ANSI, for strings. Rescinded the sloppiness that permitted
- non-octal digits in \ooo. Warning: not all compilers and libraries
- will be able to deal with \x correctly.
-
-Jan 9, 1989:
- Fixed bug that caused tempcell list to contain a duplicate.
- The fix is kludgy.
-
-Dec 17, 1988:
- Catches some more commandline errors in main.
- Removed redundant decl of modf in run.c (confuses some compilers).
- Warning: there's no single declaration of malloc, etc., in awk.h
- that seems to satisfy all compilers.
-
-Dec 7, 1988:
- Added a bit of code to error printing to avoid printing nulls.
- (Not clear that it actually would.)
-
-Nov 27, 1988:
- With fear and trembling, modified the grammar to permit
- multiple pattern-action statements on one line without
- an explicit separator. By definition, this capitulation
- to the ghost of ancient implementations remains undefined
- and thus subject to change without notice or apology.
- DO NOT COUNT ON IT.
-
-Oct 30, 1988:
- Fixed bug in call() that failed to recover storage.
-
- A warning is now generated if there are more arguments
- in the call than in the definition (in lieu of fixing
- another storage leak).
-
-Oct 20, 1988:
- Fixed %c: if expr is numeric, use numeric value;
- otherwise print 1st char of string value. still
- doesn't work if the value is 0 -- won't print \0.
-
- Added a few more checks for running out of malloc.
-
-Oct 12, 1988:
- Fixed bug in call() that freed local arrays twice.
-
- Fixed to handle deletion of non-existent array right;
- complains about attempt to delete non-array element.
-
-Sep 30, 1988:
- Now guarantees to evaluate all arguments of built-in
- functions, as in C; the appearance is that arguments
- are evaluated before the function is called. Places
- affected are sub (gsub was ok), substr, printf, and
- all the built-in arithmetic functions in bltin().
- A warning is generated if a bltin() is called with
- the wrong number of arguments.
-
- This requires changing makeprof on p167 of the book.
-
-Aug 23, 1988:
- setting FILENAME in BEGIN caused core dump, apparently
- because it was freeing space not allocated by malloc.
-
-July 24, 1988:
- fixed egregious error in toupper/tolower functions.
- still subject to rescinding, however.
-
-July 2, 1988:
- flush stdout before opening file or pipe
-
-July 2, 1988:
- performance bug in b.c/cgoto(): not freeing some sets of states.
- partial fix only right now, and the number of states increased
- to make it less obvious.
-
-June 1, 1988:
- check error status on close
-
-May 28, 1988:
- srand returns seed value it's using.
- see 1/18/90
-
-May 22, 1988:
- Removed limit on depth of function calls.
-
-May 10, 1988:
- Fixed lib.c to permit _ in commandline variable names.
-
-Mar 25, 1988:
- main.c fixed to recognize -- as terminator of command-
- line options. Illegal options flagged.
- Error reporting slightly cleaned up.
-
-Dec 2, 1987:
- Newer C compilers apply a strict scope rule to extern
- declarations within functions. Two extern declarations in
- lib.c and tran.c have been moved to obviate this problem.
-
-Oct xx, 1987:
- Reluctantly added toupper and tolower functions.
- Subject to rescinding without notice.
-
-Sep 17, 1987:
- Error-message printer had printf(s) instead of
- printf("%s",s); got core dumps when the message
- included a %.
-
-Sep 12, 1987:
- Very long printf strings caused core dump;
- fixed aprintf, asprintf, format to catch them.
- Can still get a core dump in printf itself.

-
-This is the version of awk described in "The AWK Programming Language",
-by Al Aho, Brian Kernighan, and Peter Weinberger
-(Addison-Wesley, 1988, ISBN 0-201-07981-X).
-
-Changes, mostly bug fixes and occasional enhancements, are listed
-in FIXES. If you distribute this code further, please please please
-distribute FIXES with it. If you find errors, please report them
-to bwk@bell-labs.com. Thanks.
-
-The program itself is created by
- make
-which should produce a sequence of messages roughly like this:
-
- yacc -d awkgram.y
-
-conflicts: 43 shift/reduce, 85 reduce/reduce
- mv y.tab.c ytab.c
- mv y.tab.h ytab.h
- cc -c ytab.c
- cc -c b.c
- cc -c main.c
- cc -c parse.c
- cc maketab.c -o maketab
- ./maketab >proctab.c
- cc -c proctab.c
- cc -c tran.c
- cc -c lib.c
- cc -c run.c
- cc -c lex.c
- cc ytab.o b.o main.o parse.o proctab.o tran.o lib.o run.o lex.o -lm
-
-This produces an executable a.out; you will eventually want to
-move this to some place like /usr/bin/awk.
-
-If your system does not have yacc or bison (the GNU
-equivalent), you must compile the pieces manually. We have
-included yacc output in ytab.c and ytab.h, and backup copies in
-case you overwrite them. We have also included a copy of
-proctab.c so you do not need to run maketab.
-
-NOTE: This version uses ANSI C, as you should also. We have
-compiled this without any changes using gcc -Wall and/or local C
-compilers on a variety of systems, but new systems or compilers
-may raise some new complaint; reports of difficulties are
-welcome.
-
-This also compiles with Visual C++ on all flavors of Windows,
-*if* you provide versions of popen and pclose. The file
-missing95.c contains versions that can be used to get started
-with, though the underlying support has mysterious properties,
-the symptom of which can be truncated pipe output. Beware. The
-file makefile.win gives hints on how to proceed; if you run
-vcvars32.bat, it will set up necessary paths and parameters so
-you can subsequently run nmake -f makefile.win. Beware also that
-when running on Windows under command.com, various quoting
-conventions are different from Unix systems: single quotes won't
-work around arguments, and various characters like % are
-interpreted within double quotes.
-
-This compiles without change on Macintosh OS X using gcc and
-the standard developer tools.
-
-This is also said to compile on Macintosh OS 9 systems, using the
-file "buildmac" provided by Dan Allen (danallen@microsoft.com),
-to whom many thanks.
-
-The version of malloc that comes with some systems is sometimes
-astonishly slow. If awk seems slow, you might try fixing that.
-More generally, turning on optimization can significantly improve
-awk's speed, perhaps by 1/3 for highest levels.

-.TH AWK 1
-.CT 1 files prog_other
-.SH NAME
-awk \- pattern-directed scanning and processing language
-.SH SYNOPSIS
-.B awk
-[
-.BI \-F
-.I fs
-]
-[
-.BI \-v
-.I var=value
-]
-[
-.I 'prog'
-|
-.BI \-f
-.I progfile
-]
-[
-.I file ...
-]
-.SH DESCRIPTION
-.I Awk
-scans each input
-.I file
-for lines that match any of a set of patterns specified literally in
-.IR prog
-or in one or more files
-specified as
-.B \-f
-.IR progfile .
-With each pattern
-there can be an associated action that will be performed
-when a line of a
-.I file
-matches the pattern.
-Each line is matched against the
-pattern portion of every pattern-action statement;
-the associated action is performed for each matched pattern.
-The file name
-.B \-
-means the standard input.
-Any
-.IR file
-of the form
-.I var=value
-is treated as an assignment, not a filename,
-and is executed at the time it would have been opened if it were a filename.
-The option
-.B \-v
-followed by
-.I var=value
-is an assignment to be done before
-.I prog
-is executed;
-any number of
-.B \-v
-options may be present.
-The
-.B \-F
-.IR fs
-option defines the input field separator to be the regular expression
-.IR fs.
-.PP
-An input line is normally made up of fields separated by white space,
-or by regular expression
-.BR FS .
-The fields are denoted
-.BR $1 ,
-.BR $2 ,
-\&..., while
-.B $0
-refers to the entire line.
-If
-.BR FS
-is null, the input line is split into one field per character.
-.PP
-A pattern-action statement has the form
-.IP
-.IB pattern " { " action " }
-.PP
-A missing
-.BI { " action " }
-means print the line;
-a missing pattern always matches.
-Pattern-action statements are separated by newlines or semicolons.
-.PP
-An action is a sequence of statements.
-A statement can be one of the following:
-.PP
-.EX
-.ta \w'\f(CWdelete array[expression]'u
-.RS
-.nf
-.ft CW
-if(\fI expression \fP)\fI statement \fP\fR[ \fPelse\fI statement \fP\fR]\fP

-.fi
-.RE
-.EE
-.DT
-.PP
-Statements are terminated by
-semicolons, newlines or right braces.
-An empty
-.I expression-list
-stands for
-.BR $0 .
-String constants are quoted \&\f(CW"\ "\fR,
-with the usual C escapes recognized within.
-Expressions take on string or numeric values as appropriate,
-and are built using the operators
-.B + \- * / % ^
-(exponentiation), and concatenation (indicated by white space).
-The operators
-.B
-! ++ \-\- += \-= *= /= %= ^= > >= < <= == != ?:
-are also available in expressions.
-Variables may be scalars, array elements
-(denoted
-.IB x [ i ] )
-or fields.
-Variables are initialized to the null string.
-Array subscripts may be any string,
-not necessarily numeric;
-this allows for a form of associative memory.
-Multiple subscripts such as
-.B [i,j,k]
-are permitted; the constituents are concatenated,
-separated by the value of
-.BR SUBSEP .
-.PP
-The
-.B print
-statement prints its arguments on the standard output
-(or on a file if
-.BI > file
-or
-.BI >> file
-is present or on a pipe if
-.BI | cmd
-is present), separated by the current output field separator,
-and terminated by the output record separator.
-.I file
-and
-.I cmd
-may be literal names or parenthesized expressions;
-identical string values in different statements denote
-the same open file.
-The
-.B printf
-statement formats its expression list according to the format
-(see
-.IR printf (3)) .
-The built-in function
-.BI close( expr )
-closes the file or pipe
-.IR expr .
-The built-in function
-.BI fflush( expr )
-flushes any buffered output for the file or pipe
-.IR expr .
-.PP
-The mathematical functions
-.BR exp ,
-.BR log ,
-.BR sqrt ,
-.BR sin ,
-.BR cos ,
-and
-.BR atan2
-are built in.
-Other built-in functions:
-.TF length
-.TP
-.B length
-the length of its argument
-taken as a string,
-or of
-.B $0
-if no argument.
-.TP
-.B rand
-random number on (0,1)
-.TP
-.B srand
-sets seed for
-.B rand
-and returns the previous seed.
-.TP
-.B int
-truncates to an integer value
-.TP
-.BI substr( s , " m" , " n\fB)
-the
-.IR n -character
-substring of
-.I s
-that begins at position
-.IR m
-counted from 1.
-.TP
-.BI index( s , " t" )
-the position in
-.I s
-where the string
-.I t
-occurs, or 0 if it does not.
-.TP
-.BI match( s , " r" )
-the position in
-.I s
-where the regular expression
-.I r
-occurs, or 0 if it does not.
-The variables
-.B RSTART
-and
-.B RLENGTH
-are set to the position and length of the matched string.
-.TP
-.BI split( s , " a" , " fs\fB)
-splits the string
-.I s
-into array elements
-.IB a [1] ,
-.IB a [2] ,
-\&...,
-.IB a [ n ] ,
-and returns
-.IR n .
-The separation is done with the regular expression
-.I fs
-or with the field separator
-.B FS
-if
-.I fs
-is not given.
-An empty string as field separator splits the string
-into one array element per character.
-.TP
-.BI sub( r , " t" , " s\fB)
-substitutes
-.I t
-for the first occurrence of the regular expression
-.I r
-in the string
-.IR s .
-If
-.I s
-is not given,
-.B $0
-is used.
-.TP
-.B gsub
-same as
-.B sub
-except that all occurrences of the regular expression
-are replaced;
-.B sub
-and
-.B gsub
-return the number of replacements.
-.TP
-.BI sprintf( fmt , " expr" , " ...\fB )
-the string resulting from formatting
-.I expr ...
-according to the
-.IR printf (3)
-format
-.I fmt
-.TP
-.BI system( cmd )
-executes
-.I cmd
-and returns its exit status
-.TP
-.BI tolower( str )
-returns a copy of
-.I str
-with all upper-case characters translated to their
-corresponding lower-case equivalents.
-.TP
-.BI toupper( str )
-returns a copy of
-.I str
-with all lower-case characters translated to their
-corresponding upper-case equivalents.
-.PD
-.PP
-The ``function''
-.B getline
-sets
-.B $0
-to the next input record from the current input file;
-.B getline
-.BI < file
-sets
-.B $0
-to the next record from
-.IR file .
-.B getline
-.I x
-sets variable
-.I x
-instead.
-Finally,
-.IB cmd " | getline
-pipes the output of
-.I cmd
-into
-.BR getline ;
-each call of
-.B getline
-returns the next line of output from
-.IR cmd .
-In all cases,
-.B getline
-returns 1 for a successful input,
-0 for end of file, and \-1 for an error.
-.PP
-Patterns are arbitrary Boolean combinations
-(with
-.BR "! || &&" )
-of regular expressions and
-relational expressions.
-Regular expressions are as in
-.IR egrep ;
-see
-.IR grep (1).
-Isolated regular expressions
-in a pattern apply to the entire line.
-Regular expressions may also occur in
-relational expressions, using the operators
-.BR ~
-and
-.BR !~ .
-.BI / re /
-is a constant regular expression;
-any string (constant or variable) may be used
-as a regular expression, except in the position of an isolated regular expression
-in a pattern.
-.PP
-A pattern may consist of two patterns separated by a comma;
-in this case, the action is performed for all lines
-from an occurrence of the first pattern
-though an occurrence of the second.
-.PP
-A relational expression is one of the following:
-.IP
-.I expression matchop regular-expression
-.br
-.I expression relop expression
-.br
-.IB expression " in " array-name
-.br
-.BI ( expr , expr,... ") in " array-name
-.PP
-where a relop is any of the six relational operators in C,
-and a matchop is either
-.B ~
-(matches)
-or
-.B !~
-(does not match).
-A conditional is an arithmetic expression,
-a relational expression,
-or a Boolean combination
-of these.
-.PP
-The special patterns
-.B BEGIN
-and
-.B END
-may be used to capture control before the first input line is read
-and after the last.
-.B BEGIN
-and
-.B END
-do not combine with other patterns.
-.PP
-Variable names with special meanings:
-.TF FILENAME
-.TP
-.B CONVFMT
-conversion format used when converting numbers
-(default
-.BR "%.6g" )
-.TP
-.B FS
-regular expression used to separate fields; also settable
-by option
-.BI \-F fs.
-.TP
-.BR NF
-number of fields in the current record
-.TP
-.B NR
-ordinal number of the current record
-.TP
-.B FNR
-ordinal number of the current record in the current file
-.TP
-.B FILENAME
-the name of the current input file
-.TP
-.B RS
-input record separator (default newline)
-.TP
-.B OFS
-output field separator (default blank)
-.TP
-.B ORS
-output record separator (default newline)
-.TP
-.B OFMT
-output format for numbers (default
-.BR "%.6g" )
-.TP
-.B SUBSEP
-separates multiple subscripts (default 034)
-.TP
-.B ARGC
-argument count, assignable
-.TP
-.B ARGV
-argument array, assignable;
-non-null members are taken as filenames
-.TP
-.B ENVIRON
-array of environment variables; subscripts are names.
-.PD
-.PP
-Functions may be defined (at the position of a pattern-action statement) thus:
-.IP
-.B
-function foo(a, b, c) { ...; return x }
-.PP
-Parameters are passed by value if scalar and by reference if array name;
-functions may be called recursively.
-Parameters are local to the function; all other variables are global.
-Thus local variables may be created by providing excess parameters in
-the function definition.
-.SH EXAMPLES
-.TP
-.EX
-length($0) > 72
-.EE
-Print lines longer than 72 characters.
-.TP
-.EX
-{ print $2, $1 }
-.EE
-Print first two fields in opposite order.
-.PP
-.EX
-BEGIN { FS = ",[ \et]*|[ \et]+" }
- { print $2, $1 }
-.EE
-.ns
-.IP
-Same, with input fields separated by comma and/or blanks and tabs.
-.PP
-.EX
-.nf
- { s += $1 }
-END { print "sum is", s, " average is", s/NR }
-.fi
-.EE
-.ns
-.IP
-Add up first column, print sum and average.
-.TP
-.EX
-/start/, /stop/
-.EE
-Print all lines between start/stop pairs.
-.PP
-.EX
-.nf
-BEGIN { # Simulate echo(1)
- for (i = 1; i < ARGC; i++) printf "%s ", ARGV[i]
- printf "\en"
- exit }

-.SH BUGS
-There are no explicit conversions between numbers and strings.
-To force an expression to be treated as a number add 0 to it;
-to force it to be treated as a string concatenate
-\&\f(CW""\fP to it.
-.br
-The scope rules for variables in functions are a botch;
-the syntax is worse.

-Note added June, 2002:
-
-With the advent of OS X, life is simpler: if you have the developer
-tools installed, the standard awk makefile and gcc works fine, and
-you can ignore the rest of this file, which is now hereby deprecated.
-
-
-
-
-This file contains a make shell script and a version of the file
-missing95.c for the Mac, courtesy of Dan Allen.

-make shell script:
-
-# MPW Shell script to build Awk using Apple's MRC compiler.
-# 22 Jan 1999 - Created by Dan Allen.
-# 25 Mar 1999 - Updated for newer Awk.
-#
-# Porting notes for the Mac:
-#
-# 1. main in main.c needs to have its prototype changed to:
-#
-# int main(int argc, char *argv[], char *environ[])
-#
-# 2. popen and pclose in missing95.c need to have as their body the
-# older style
-#
-# return NULL;
-#
-# as parallel pipes are not supported by MPW.
-#
-# 3. To make your Mac more responsive while long awk scripts run,
-# you may want to add some SpinCursor calls to support cooperative multitasking.
-#
-# All of these minor changes can be put under "#ifdef powerc" for portability's sake.
