Also get rid of + a few generated files. + +Fixed off-by-one bug in string concatenation code. + +Fix for use of array that is passed in from a previous function parameter. + Addition to test suite for above. + +A number of changes associated with changing NF and access to fields + beyond the end of the current record. + +Change to missing/memcmp.c to avoid seg. fault on zero length input. + +Updates to test suite (including some inadvertently left out of the last patch) + to invoke sh explicitly (rather than rely on #!/bin/sh) and remove some + junk files. test/chem/good updated to correspond to bug fixes. + +Changes from 2.13.0 to 2.13.1 +----------------------------- + +More configs and PORTS. + +Fixed bug wherein a simple division produced an erroneous FPE, caused by + the Cray division workaround -- that code is now #ifdef'd only for + Cray *and* fixed. + +Fixed bug in modulus implementation -- it was very close to the above + code, so I noticed it. + +Fixed portability problem with limits.h in missing.c + +Fixed portability problem with tzname and daylight -- define TZNAME_MISSING + if strftime() is missing and tzname is also. + +Better support for Latin-1 character set. + +Fixed portability problem in test Makefile. + +Updated PROBLEMS file. + +=============================== gawk-2.13 released ========================= +Changes from 2.12.42 to 2.12.43 +------------------------------- + +Typo in awk.y + +Fixed up strftime.3 and added doc. for %V. + +Changes from 2.12.41 to 2.12.42 +------------------------------- + +Fixed bug in devopen() -- if you had write permission in /dev, + it would just create /dev/stdout etc.!! + +Final (?) VMS update. + +Make NeXT use GFMT_WORKAROUND + +Fixed bug in sub_common() for substitute on zero-length match. Improved the + code a bit while I was at it. + +Fixed grammar so that $i++ parses as ($i)++ + +Put support/* back in the distribution (didn't I already do this?!) + +Changes from 2.12.40 to 2.12.41 +------------------------------- + +VMS workaround for broken %g format. + +Changes from 2.12.39 to 2.12.40 +------------------------------- + +Minor man page update. + +Fixed latent bug in redirect(). + +Changes from 2.12.38 to 2.12.39 +------------------------------- + +Updates to test suite -- remove dependence on changing gawk.1 man page. + +Changes from 2.12.37 to 2.12.38 +------------------------------- + +Fixed bug in use of *= without whitespace following. + +VMS update. + +Updates to man page. + +Option handling updates in main.c + +test/manyfiles redone and added to bigtest. + +Fixed latent (on Sun) bug in handling of save_fs. + +Changes from 2.12.36 to 2.12.37 +------------------------------- + +Update REL in Makefile-dist. Incorporate test suite into main distribution. + +Minor fix in regtest. + +Changes from 2.12.35 to 2.12.36 +------------------------------- + +Release takes on dual personality -- 2.12.36 and 2.13.0 -- any further + patches before public release won't count for 2.13, although they will for + 2.12 -- be careful to avoid confusion! patchlevel.h will be the last thing + to change. + +Cray updates to deal with arithmetic problems. + +Minor test suite updates. + +Fixed latent bug in parser (freeing memory). + +Changes from 2.12.34 to 2.12.35 +------------------------------- + +VMS updates. + +Flush stdout at top of err() and stderr at bottom. + +Fixed bug in eval_condition() -- it wasn't testing for MAYBE_NUM and + doing the force_number(). + +Included the missing manyfiles.awk and a new test to catch the above bug which + I am amazed wasn't already caught by the test suite -- it's pretty basic. + +Changes from 2.12.33 to 2.12.34 +------------------------------- + +Atari updates -- including bug fix. + +More VMS updates -- also nuke vms/version.com. + +Fixed bug in handling of large numbers of redirections -- it was probably never + tested before (blush!). + +Minor rearrangement of code in r_force_number(). + +Made chem and regtest tests a bit more portable (Ultrix again). + +Added another test -- manyfiles -- not invoked under any other test -- very Unix + specific. + +Rough beginning of LIMITATIONS file -- need my AWK book to complete it. + +Changes from 2.12.32 to 2.12.33 +------------------------------- + +Expunge debug.? from various files. + +Remove vestiges of Floor and Ceil kludge. + +Special case integer division -- mainly for Cray, but maybe someone else + will benefit. + +Workaround for iop_close closing an output pipe descriptor on Cray -- + not conditional since I think it may fix a bug on SGI as well and I don't + think it can hurt elsewhere. + +Fixed memory leak in assoc_lookup(). + +Small cleanup in test suite. + +Changes from 2.12.31 to 2.12.32 +------------------------------- + +Nuked debug.c and debugging flag -- there are better ways. + +Nuked version.sh and version.c in subdirectories. + +Fixed bug in handling of IGNORECASE. + +Fixed bug when FIELDWIDTHS was set via -v option. + +Fixed (obscure) bug when $0 is assigned a numerical value. + +Fixed so that escape sequences in command-line assignments work (as it already + said in the comment). + +Added a few cases to test suite. + +Moved support/* back into distribution. + +VMS updates. + +Changes from 2.12.30 to 2.12.31 +------------------------------- + +Cosmetic manual page changes. + +Updated sunos3 config. + +Small changes in test suite including renaming files over 14 chars. in length. + +Changes from 2.12.29 to 2.12.30 +------------------------------- + +Bug fix for many string concatenations in a row. + +Changes from 2.12.28 to 2.12.29 +------------------------------- + +Minor cleanup in awk.y + +Minor VMS update. + +Minor atari update. + +Changes from 2.12.27 to 2.12.28 +------------------------------- + +Got rid of the debugging goop in eval.c -- there are better ways. + +Sequent port. + +VMS changes left out of the last patch -- sigh! config/vms.h renamed + to config/vms-conf.h. + +Fixed missing/tzset.c + +Removed use of gcvt() and GCVT_MISSING -- turns out it was no faster than + sprintf("%g") and caused all sorts of portability headaches. + +Tuned get_field() -- it was unnecessarily parsing the whole record on reference + to $0. + +Tuned interpret() a bit in the rule_node loop. + +In r_force_number(), worked around bug in Uglix strtod() and got rid of + ugly do{}while(0) at Michal's urging. + +Replaced do_deref() and deref with unref(node) -- much cleaner and a bit faster. + +Got rid of assign_number() -- contrary to comment, it was no faster than + just making a new node and freeing the old one. + +Replaced make_number() and tmp_number() with macros that call mk_number(). + +Changed freenode() and newnode() into macros -- the latter is getnode() + which calls more_nodes() as necessary. + +Changes from 2.12.26 to 2.12.27 +------------------------------- + +Completion of Cray 2 port (includes a kludge for floor() and ceil() + that may go or be changed -- I think that it may just be working around + a bug in chem that is being tweaked on the Cray). + +More VMS updates. + +Moved kludge over yacc's insertion of malloc and realloc declarations + from protos.h to the Makefile. + +Added a lisp interpreter in awk to the test suite. (Invoked under + bigtest.) + +Cleanup in r_force_number() -- I had never gotten around to a thorough + profile of the cache code and it turns out to be not worth it. + +Performance boost -- do lazy force_number()'ing for fields etc. i.e. + flag them (MAYBE_NUM) and call force_number only as necessary. + +Changes from 2.12.25 to 2.12.26 +------------------------------- + +Rework of regexp stuff so that dynamic regexps have reasonable + performance -- string used for compiled regexp is stored and + compared to new string -- if same, no recompilation is necessary. + Also, very dynamic regexps cause dfa-based searching to be turned + off. + +Code in dev_open() is back to returning fileno(std*) rather than + dup()ing it. This will be documented. Sorry for the run-around + on this. + +Minor atari updates. + +Minor vms update. + +Missing file from MSDOS port. + +Added warning (under lint) if third arg. of [g]sub is a constant and + handle it properly in the code (i.e. return how many matches). + +Changes from 2.12.24 to 2.12.25 +------------------------------- + +MSDOS port. + +Non-consequential changes to regexp variables in preparation for + a more serious change to fix a serious performance problem. + +Changes from 2.12.23 to 2.12.24 +------------------------------- + +Fixed bug in output flushing introduced a few patches back. This caused + serious performance losses. + +Changes from 2.12.22 to 2.12.23 +------------------------------- + +Accidently left config/cray2-60 out of last patch. + +Added some missing dependencies to Makefile. + +Cleaned up mkconf a bit; made yacc the default parser (no alloca needed, + right?); added rs6000 hook for signed characters. + +Made regex.c with NO_ALLOCA undefined work. + +Fixed bug in dfa.c for systems where free(NULL) bombs. + +Deleted a few cant_happen()'s that *really* can't hapen. + +Changes from 2.12.21 to 2.12.22 +------------------------------- + +Added to config stuff the ability to choose YACC rather than bison. + +Fixed CHAR_UNSIGNED in config.h-dist. + +Second arg. of strtod() is char ** rather than const char **. + +stackb is now initially malloc()'ed since it may be realloc()'ed. + +VMS updates. + +Added SIZE_T_MISSING to config stuff and a default typedef to awk.h. + (Maybe it is not needed on any current systems??) + +re_compile_pattern()'s size is now size_t unconditionally. + +Changes from 2.12.20 to 2.12.21 +------------------------------- + +Corrected missing/gcvt.c. + +Got rid of use of dup2() and thus DUP_MISSING. + +Updated config/sgi33. + +Turned on (and fixed) in cmp_nodes() the behaviour that I *hope* will be in + POSIX 1003.2 for relational comparisons. + +Small updates to test suite. + +Changes from 2.12.19 to 2.12.20 +------------------------------- + +Sloppy, sloppy, sloppy!! I didn't even try to compile the last two + patches. This one fixes goofs in regex.c. + +Changes from 2.12.18 to 2.12.19 +------------------------------- + +Cleanup of last patch. + +Changes from 2.12.17 to 2.12.18 +------------------------------- + +Makefile renamed to Makefile-dist. + +Added alloca() configuration to mkconf. (A bit kludgey.) Just + add a single line containing ALLOCA_PW, ALLOCA_S or ALLOCA_C + to the appropriate config file to have Makefile-dist edited + accordingly. + +Reorganized output flushing to correspond with new semantics of + devopen() on "/dev/std*" etc. + +Fixed rest of last goof!! + +Save and restore errno in do_pathopen(). + +Miscellaneous atari updates. + +Get rid of the trailing comma in the NODETYPE definition (Cray + compiler won't take it). + +Try to make the use of `const' consistent since Cray compiler is + fussy about that. See the changes to `basename' and `myname'. + +It turns out that, according to section 3.8.3 (Macro Replacement) + of the ANSI Standard: ``If there are sequences of preprocessing + tokens within the list of arguments that would otherwise act as + preprocessing directives, the behavior is undefined.'' That means + that you cannot count on the behavior of the declaration of + re_compile_pattern in awk.h, and indeed the Cray compiler chokes on it. + +Replaced alloca with malloc/realloc/free in regex.c. It was much simpler + than expected. (Inside NO_ALLOCA for now -- by default no alloca.) + +Added a configuration file, config/cray60, for Unicos-6.0. + +Changes from 2.12.16 to 2.12.17 +------------------------------- + +Ooops. Goofed signal use in last patch. + +Changes from 2.12.15 to 2.12.16 +------------------------------- + +RENAMED *_dir to just * (e.g. missing_dir). + +Numerous VMS changes. + +Proper inclusion of atari and vms files. + +Added experimental (ifdef'd out) RELAXED_CONTINUATION and DEFAULT_FILETYPE + -- please comment on these! + +Moved pathopen() to io.c (sigh). + +Put local directory ahead in default AWKPATH. + +Added facility in mkconf to echo comments on stdout: lines beginning + with "#echo " will have the remainder of the line echoed when mkconf is run. + Any lines starting with "#" will otherwise be treated as comments. The + intent is to be able to say: + "#echo Make sure you uncomment alloca.c in the Makefile" + or the like. + +Prototype fix for V.4 + +Fixed version_string to not print leading @(#). + +Fixed FIELDWIDTHS to work with strict (turned out to be easy). + +Fixed conf for V.2. + +Changed semantics of /dev/fd/n to be like on real /dev/fd. + +Several configuration and updates in the makefile. + +Updated manpage. + +Include tzset.c and system.c from missing_dir that were accidently left out of + the last patch. + +Fixed bug in cmdline variable assignment -- arg was getting freed(!) in + call to variable. + +Backed out of parse-time constant folding for now, until I can figure out + how to do it right. + +Fixed devopen() so that getline <"-" works. + +Changes from 2.12.14 to 2.12.15 +------------------------------- + +Changed config/* to a condensed form that can be used with mkconf to generate + a config.h from config.h-dist -- much easier to maintain. Please chaeck + carefully against what you had before for a particular system and report + any problems. vms.h remains separate since the stuff at the bottom + didn't quite fit the mkconf model -- hopefully cleared up later. + +Fixed bug in grammar -- didn't allow function definition to be separated from + other rules by a semi-colon. + +VMS fix to #includes in missing.c -- should we just be including awk.h? + +Updated README for texinfo.tex version. + +Updating of copyright in all .[chy] files. + +Added but commented out Michal's fix to strftime. + +Added tzset() emulation based on Rick Adams' code. Added TZSET_MISSING to + config.h-dist. + +Added strftime.3 man page for missing_dir + +More posix: func, **, **= don't work in -W posix + +More lint: ^, ^= not in old awk + +gawk.1: removed ref to -DNO_DEV_FD, other minor updating. + +Style change: pushbak becomes pushback() in yylex(). + +Changes from 2.12.13 to 2.12.14 +------------------------------- + +Better (?) organization of awk.h -- attempt to keep all system dependencies + near the top and move some of the non-general things out of the config.h + files. + +Change to handling of SYSTEM_MISSING. + +Small change to ultrix config. + +Do "/dev/fd/*" etc. checking at runtime. + +First pass at VMS port. + +Improvements to error handling (when lexeme spans buffers). + +Fixed backslash handling -- why didn't I notice this sooner? + +Added programs from book to test suite and new target "bigtest" to Makefile. + +Changes from 2.12.12 to 2.12.13 +------------------------------- + +Recognize OFS and ORS specially so that OFS = 9 works without efficiency hit. + Took advantage of opportunity to tune do_print*() for about 10% win on a + print with 5 args (i.e. small but significant). + +Somewhat pervasive changes to reconcile CONVFMT vs. OFMT. + +Better initialization of builtin vars. + +Make config/* consistent wrt STRTOL_MISSING. + +Small portability improvement to alloca.s + +Improvements to lint code in awk.y + +Replaced strtol() with a better one by Chris Torek. + +Changes from 2.12.11 to 2.12.12 +------------------------------- + +Added PORTS file to record successful ports. + +Added #define const to nothing if not STDC and added const to strtod() header. + +Added * to printf capabilities and partially implemented ' ' and '+' (has an + effect for %d only, silently ignored for other formats). I'm afraid that's + as far as I want to go before I look at a complete replacement for + do_sprintf(). + +Added warning for /regexp/ on LHS of MATCHOP. + +Changes from 2.12.10 to 2.12.11 +------------------------------- + +Small Makefile improvements. + +Some remaining nits from the NeXT port. + +Got rid of bcopy() define in awk.h -- not needed anymore (??) + +Changed private in builtin.c -- it is special on Sequent. + +Added subset implementation of strtol() and STRTOL_MISSING. + +A little bit of cleanup in debug.c, dfa.c. + +Changes from 2.12.9 to 2.12.10 +------------------------------ + +Redid compatability checking and checking for # of args. + +Removed all references to variables[] from outside awk.y, in preparation + for a more abstract interface to the symbol table. + +Got rid of a remaining use of bcopy() in regex.c. + +Changes from 2.12.8 to 2.12.9 +----------------------------- + +Portability improvements for atari, next and decstation. + +Bug fix in substr() -- wasn't handling 3rd arg. of -1 properly. + +Manpage updates. + +Moved support from src release to doc release. + +Updated FUTURES file. + +Added some "lint" warnings. + +Changes from 2.12.7 to 2.12.8 +----------------------------- + +Changed time() to systime(). + +Changed warning() in snode() to fatal(). + +strftime() now defaults second arg. to current time. + +Changes from 2.12.6 to 2.12.7 +----------------------------- + +Fixed bug in sub_common() involving inadequate allocation of a buffer. + +Added some missing files to the Makefile. + +Changes from 2.12.5 to 2.12.6 +----------------------------- + +Fixed bug wherein non-redirected getline could call iop_close() just + prior to a call from do_input(). + +Fixed bug in handling of /dev/stdout and /dev/stderr. + +Changes from 2.12.4 to 2.12.5 +----------------------------- + +Updated README and support directory. + +Changes from 2.12.3 to 2.12.4 +----------------------------- + +Updated CHANGES and TODO (should have been done in previous 2 patches). + +Changes from 2.12.2 to 2.12.3 +----------------------------- + +Brought regex.c and alloca.s into line with current FSF versions. + +Changes from 2.12.1 to 2.12.2 +----------------------------- + +Portability improvements; mostly moving system prototypes out of awk.h + +Introduction of strftime. + +Use of CONVFMT. + +Changes from 2.12 to 2.12.1 +----------------------------- + +Consolidated treatment of command-line assignments (thus correcting the +-v treatment). + +Rationalized builtin-variable handling into a table-driven process, thus +simplifying variable() and eliminating spc_var(). + +Fixed bug in handling of command-line source that ended in a newline. + +Simplified install() and lookup(). + +Did away with double-mallocing of identifiers and now free second and later +instances of a name, after the first gets installed into the symbol table. + +Treat IGNORECASE specially, simplifying a lot of code, and allowing +checking against strict conformance only on setting it, rather than on each +pattern match. + +Fixed regexp matching when IGNORECASE is non-zero (broken when dfa.c was +added). + +Fixed bug where $0 was not being marked as valid, even after it was rebuilt. +This caused mangling of $0. + + +Changes from 2.11.1 to 2.12 +----------------------------- + +Makefile: + +Portability improvements in Makefile. +Move configuration stuff into config.h + +FSF files: + +Synchronized alloca.[cs] and regex.[ch] with FSF. + +array.c: + +Rationalized hash routines into one with a different algorithm. +delete() now works if the array is a local variable. +Changed interface of assoc_next() and avoided dereferencing past the end of the + array. + +awk.h: + +Merged non-prototype and prototype declarations in awk.h. +Expanded tree_eval #define to short-circuit more calls of r_tree_eval(). + +awk.y: + +Delinted some of the code in the grammar. +Fixed and improved some of the error message printing. +Changed to accomodate unlimited length source lines. +Line continuation now works as advertised. +Source lines can be arbitrarily long. +Refined grammar hacks so that /= assignment works. Regular expressions + starting with /= are recognized at the beginning of a line, after && or || + and after ~ or !~. More contexts can be added if necessary. +Fixed IGNORECASE (multiple scans for backslash). +Condensed expression_lists in array references. +Detect and warn for correct # args in builtin functions -- call most of them + with a fixed number (i.e. fill in defaults at parse-time rather than at + run-time). +Load ENVIRON only if it is referenced (detected at parse-time). +Treat NF, FS, RS, NR, FNR specially at parse time, to improve run time. +Fold constant expressions at parse time. +Do make_regexp() on third arg. of split() at parse tiem if it is a constant. + +builtin.c: + +srand() returns 0 the first time called. +Replaced alloca() with malloc() in do_sprintf(). +Fixed setting of RSTART and RLENGTH in do_match(). +Got rid of get_{one,two,three} and allowance for variable # of args. at + run-time -- this is now done at parse-time. +Fixed latent bug in [g]sub whereby changes to $0 would never get made. +Rewrote much of sub_common() for simplicity and performance. +Added ctime() and time() builtin functions (unless -DSTRICT). ctime() returns + a time string like the C function, given the number of seconds since the epoch + and time() returns the current time in seconds. +do_sprintf() now checks for mismatch between format string and number of + arguments supplied. + +dfa.c + +This is borrowed (almost unmodified) from GNU grep to provide faster searches. + +eval.c + +Node_var, Node_var_array and Node_param_list handled from macro rather + than in r_tree_eval(). +Changed cmp_nodes() to not do a force_number() -- this, combined with a + force_number() on ARGV[] and ENVIRON[] brings it into line with other awks +Greatly simplified cmp_nodes(). +Separated out Node_NF, Node_FS, Node_RS, Node_NR and Node_FNR in get_lhs(). +All adjacent string concatenations now done at once. + +field.c + +Added support for FIELDWIDTHS. +Fixed bug in get_field() whereby changes to a field were not always + properly reflected in $0. +Reordered tests in parse_field() so that reference off the end of the buffer + doesn't happen. +set_FS() now sets *parse_field i.e. routine to call depending on type of FS. +It also does make_regexp() for FS if needed. get_field() passes FS_regexp + to re_parse_field(), as does do_split(). +Changes to set_field() and set_record() to avoid malloc'ing and free'ing the + field nodes repeatedly. The fields now just point into $0 unless they are + assigned to another variable or changed. force_number() on the field is + *only* done when the field is needed. + +gawk.1 + +Fixed troff formatting problem on .TP lines. + +io.c + +Moved some code out into iop.c. +Output from pipes and system() calls is properly synchronized. +Status from pipe close properly returned. +Bug in getline with no redirect fixed. + +iop.c + +This file contains a totally revamped get_a_record and associated code. + +main.c + +Command line programs no longer use a temporary file. +Therefore, tmpnam() no longer required. +Deprecated -a and -e options -- they will go away in the next release, + but for now they cause a warning. +Moved -C, -V, -c options to -W ala posix. +Added -W posix option: throw out \x +Added -W lint option. + + +node.c + +force_number() now allows pure numerics to have leading whitespace. +Added make_string facility to optimize case of adding an already malloc'd + string. +Cleaned up and simplified do_deref(). +Fixed bug in handling of stref==255 in do_deref(). + +re.c + +contains the interface to regexp code + +Changes from 2.11.1 to FSF version of same +------------------------------------------ +Thu Jan 4 14:19:30 1990 Jim Kingdon (kingdon at albert) + + * Makefile (YACC): Add -y to bison part. + + * missing.c: Add #include <stdio.h>. + +Sun Dec 24 16:16:05 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) + + * * Makefile: Add (commented out) default defines for Sony News. + + * awk.h: Move declaration of vprintf so it will compile when + -DVPRINTF_MISSING is defined. + +Mon Nov 13 18:54:08 1989 Robert J. Chassell (bob at apple-gunkies.ai.mit.edu) + + * gawk.texinfo: changed @-commands that are not part of the + standard, currently released texinfmt.el to those that are. + Otherwise, only people with the as-yet unreleased makeinfo.c can + format this file. + Changes from 2.11beta to 2.11.1 (production) -------------------------------------------- |
