* [differences between cumulative patch application and perl5.004_01]perl-5.004_01Tim Bunce1997-06-111-4/+5
| | | | | | | | | [editor's note: The changes between this and 5.004 were processed from the m1t2 release, which was a bad idea as it was the _01 release which had the final corrected attributions. The differences between the various m*t* releases do that; I considered it most valuable just to look at the _NN releases. Many patches have been separated out and/or applied from the p5p archives nonetheless.]

| | | | | | | | | | | | | | | | | [editor's note: no patch file was found for this release, so no fine-grained changes] I can't find the password for our ftp server, so I had to drop it into ftp://ftp.sems.com/pub/incoming/perl5.002b3.tar.gz, which is a drop directory you can't ls. The current plan is that Andy is gonna whack on this a little more, and then release a gamma in a few days when he's happy with it. So don't get carried away. This is now *late* beta. In other words, have less than the appropriate amount of fun. :-) Larry

This is a consolidation patch. It contains many of the most commonly applied or agreed-to patches that have been circulating since patch.1m. It also changes the 'unofficial patchlevel' in perl.c. There are some problems (see items marked with '***'). I will attempt to address those in a patch.1o in a few days. This patch contains the following packages: My Jumbo Configure patch vs. 1m, with subsequent patches 1, 2, and 3. Mainly, this provides easier use of local libraries, documents the installation process in a new INSTALL file, moves important questions towards the beginning, and improves detection of signal names (mostly for Linux). xsubpp-1.922. Patches from Larry: eval "1" memory leak patch (as modified by GSAR to apply to 5.001m). NETaa14551 Infinite loop in formats, NETaa13729 scope.c patch (fixed problems on AIX and others) NETaa14138 "substr() & s///" (pp_hot.c) Patches from ftp.perl.com: ftp://ftp.perl.com/pub/perl/src/patches/closure-bug.patch, version of 20 Sep 1995 Includes fix for NETaa14347 (32k limit in regex), and other fixes. ftp://ftp.perl.com/pub/perl/src/patches/debugger.patch, version of 27 Aug 1995 ftp://ftp.perl.com/pub/perl/src/patches/glob-undef.patch, version of 4 Sep 1995 NETaa14421 $_ doesn't undef ftp://ftp.perl.com/pub/perl/src/patches/op-segfault.patch, version of 21 Aug 1995 ftp://ftp.perl.com/pub/perl/src/patches/warn-ref-hash-key.patch, version of 5 Jun 1995 Tim Bunce's Jumbo DynaLoader patch for Perl5.001m, which is NETaa14636 Jumbo DynaLoader patch for Perl5.001m, and Additional patch for NETaa14636 Jumbo DynaLoader patch for Perl5.001m version of 09 Oct 1995. ***This needs some additional parentheses.*** MakeMaker-5.00. Supercedes NETaa13540 (VMS MakeMaker patches). (Updates minimod.PL as well.) ***This has a couple of minor problems. pod2man is run even if it isn't available. LD_RUN_PATH gets set to some mysterious values.*** NETaa14657 Paul Marquess Net::Ping patch. I've included Net-Ping-1.00. NETaa14661 Dean Roehrich DProf. Installed as ext/Devel/DProf. Configure should pick this up automatically. (5 Apr 1995 version.) NETaa13742 Jack Shirazi Socket in 5.001. I've also included his socket.t test in t/lib/socket.t. c2ph-1.7. Dean's perlapi patches of Oct 12, 1995, which superceded those of Oct 8, 1995. This is the one that did mv perlapi.pid perlxs.pod. NETaa14310 Tim Bunce A trivial patch for configpm (handy for shell scripts) DB_File-1.0 patch from Paul Marquess (pmarquess@bfsec.bt.co.uk) last modified 7th October 1995 version 1.0 Added or updated the following hints files: hints/hpux.sh hints/ncr_tower.sh hints/netbsd.sh hints/ultrix.sh Patch and enjoy.

This necessitated two changes to the test suite: comp/cpp.t is now a front end that punts if cppstdin is not yet available (the old perl4 trick doesn't work for perl5). The op/misc.t test ./perl -P -e 'use POSIX;' has been dropped since I couldn't think of an elegant way to bypass it for systems that need the cppstdin wrapper. Grand autoload patch included (minus the installperl, lib/, and ext/ changes). The lib/ changes are in patch.1g, and the ext/ changes are in patch.1h. Better detection and use of stdio variants, especially on SVR4. Sarathy's consolidated patches (for ties) included. New filter stuff included. Three patches from Larry (gv.c, toke.c, pp_ctl.c) Patch and enjoy, Andy Dougherty doughera@lafcol.lafayette.edu Dept. of Physics Lafayette College Easton, PA 18042 Here's the file-by-file breakdown of what's included: Changes.Conf Document changes in the Configure & build process. Configure Upgrade to metaconfig PL55. Add /opt hierarchy to paths searched for programs. Tye McQueen's updated std stdio testing. Prompting for installation info for perl module pages. Add possible SITELIB to include site-specific include directories. By default this is disabled, but it seemed a neat idea now that the standard perl library is getting so big. Check that the compiler chosen exists and actually supports the options the user specified. Correctly sort multiple shared library version numbers. Use a compile & link test for gconvert(), dlopen(), and dlerror(). Do not include build directory name in cppstdin wrapper. MANIFEST Updated. Makefile.SH Reorganized a bit to support separate install.perl and install.man targets to use the new installman script and to accomodate those who don't want to install the man pages. Organize cleanup of .SH files a little better. No longer automatically make the pod/*.man files. This is done by installman only if requested. Include additional error messages and info for regenerating the automatically maintained header files. Add 'minitest' target. README Updated.

(ISC 4.1 was passing the test, but couldn't cast in an argument list.) Suggest -fpic for dynamic loading if you're using GNU CC under any name.

In particular, the FIXSTATUS macros were handing int's to U_L(). Remove unnecessary HAS_FMOD testing (See util.c). proto.h Remove my_fmod() prototype. (See util.c) sv.h Fix GV/CV typo. util.c Simplified cast_i32() and cast_iv() to mimic what *actually* happens on a SPARC running SunOS 4.1.3. (Previously, they did some complicated fmod() calculation. I've since discovered that's not what happens on the SPARC.) With this change, fmod() is no longer necessary. Hence my_fmod is removed. This also means the HAS_FMOD and HAS_DREM tests are no longer needed in Configure, so they are gone too. vms/config.vms Remove unnecessary HAS_FMOD and HAS_DREM defines. x2p/Makefile.SH Silence byacc-related things.

This patch fixes all remaining problems that I am aware of, and for which I have a solution. It also updates some hint files and documentation. Here's what's new: Configure Protect against spaces in uname -m output (unicos). Look in <stdlib.h> for malloctype and freetype. Check if user has void free() or int free(). Look in linux/signal.h for signal names. MANIFEST MANIFEST.new Two new hint files: cxux.sh and PowerUNIX.sh. Sorted. README Indicate what gets installed and where it usually goes. Thanks to Hallvard B. Furuseth <h.b.furuseth@usit.uio.no> for suggesting this. U/Myinit.U Update extliblist comment. U/dist3_051.pat This file contains patches to dist 3 (PL 51) that I used to generate Configure for perl. U/mallocsrc.U Look in <stdlib.h> for malloctype and freetype. Check if user has void free() or int free(). config_h.SH config.H Add Free_t to handle void free() vs. int free(). ext/DynaLoader/README Updated comment. ext/POSIX/POSIX.pm creat() has 2 arguments, not 3 (thanks, Paul). ext/POSIX/POSIX.xs Fix return type of lseek. ext/SDBM_File/sdbm/sdbm.h Add I_STDLIB guard on #include <stdlib.h> ext/util/extliblist Add note indicating this is obsolete. Don't remove it because people might be using it for their own private extensions. hints/PowerUNIX.sh hints/cxux.sh New files. Written by Tom.Horsley@mail.hcsc.com hints/linux.sh Simplified. lib/ExtUtils/MakeMaker.pm Typo fixed, only affected aix? malloc.c Allow for possible int free(). perl.h pp_sys.c util.c If the user is not using vfork, move the #define vfork fork util after various #include files. Since vfork() and fork() might have different prototypes, the #define could cause a conflict in system header files. (Reported for 386bsd.) Makefile.SH make realclean will remove h2xs and makeaperl (but leave behind the .SH versions, of course).

This changed a variety of things, mostly related to selecting and changing the installation prefix. Handle csh, sed, and byacc no matter what the setting of d_portable. (This was causing glob problems in patch.0i). Set d_portable to default to 'y'. It doesn't matter anyway, but gives people a warm fuzzy feeling. Remove useless d_group and d_passwd tests. Add check for <sys/stat.h>. Improve & generalize AIX version detection. Consider /opt/man/man1 as a possible place to install man pages. Be a little more robust about OS version changes when deciding if the output of uname -a has really changed. MANIFEST MANIFEST.new Added hints/mpeix.sh. README Tell users the Configure defaults are probably right. Makefile.SH Better detection of whether user has byacc. Use $(MAKE) instead of make. U/Loc_sed.U Works again with d_portable='define'. U/Myinit.U Set d_portable=define as default. U/d_byacc.U Detect whether user has byacc even if d_portable=define. U/d_csh.U Works again with d_portable='define'. U/d_group.U Empty file to avoid useless metaconfig test. U/d_passwd.U Empty file to avoid useless metaconfig test. U/dist.patch This file contains two minor updates to dist3 PL50 that were used to generage Configure. U/i_sysstat.U New test. See if sys/stat.h is available. config.H Updated. config_h.SH Updated to metaconfig patchlevel 50. ext/NDBM_File/Makefile.PL ext/ODBM_File/Makefile.PL Add -lucb for SVR4 systems. handy.h Protect agains g++-2.6.3, which predefines bool. g++ can be used to compile an extension, but not perl itself. Still, the extension will #include "perl.h", which eventually gets "handy.h", which #define's bool. If this happens to you, add -DHAS_BOOL to your ccflags in your extension, or else ensure that _G_config.h is #include'd before perl.h. (_G_config.h will define _G_HAVE_BOOL, if indeed your version of g++ has bool.) hints/aix.sh Updated. Handles AIX 3.2.x and 4.1. Comments included! hints/hpux_9.sh Updated. hints/irix_4.sh Updated. Includes comments for IRIX 4.0.4 hints/linux.sh Updated. Beginnings of ELF support added, but completely untested. hints/mpeix.sh New hint file. hints/solaris_2.sh Useless ccflags="$ccflags" line removed. hints/svr4.sh Updated. installperl Doesn't use Config anymore (it already reads config.sh directly. That's probably backwards, but, oh well. Install perl.exp for AIX. lib/ExtUtils/MakeMaker.pm Upgraded from 4.01 to 4.03. makedepend.SH Use $MAKE instead of plain make. Index: op.c Remove overlapping strcpy(). perl.h Add test for <sys/stat.h>. Delete unused VOIDSIG stuff. Delete unused typedef struct lstring Lstring; perl_exp.SH Add safexxxx calls. pp_sys.c Delete wayward break in HAS_ALARM section. proto.h Change true and false (!) in function prototypes to please g++-2.6.3, which has true and false built in. (See notes for handy.h.) Index: unixish.h Long-overdue housekeeping. HAS_GROUP and HAS_PASSWD are always defined. util.c Yet another (char*) cast for bcmp. vms/config.vms Changed comments to match unixish.h. writemain.SH Now correctly handles nested static extensions. Recent MakeMakers have moved where they get built. x2p/a2p.h More definitions that will doubtless cause trouble somewhere else. x2p/a2py.c x2p/walk.c Remove unprotected char *strchr();
* perl5.000 patch.0g: [various portability fixes, and use latest metaconfig ↵Andy Dougherty1995-01-181-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for Configure] This patch incorporates various portability fixes and uses the latest metaconfig to generate Configure (and config_h.SH). It would take a long time to summarize all that I've changed. I haven't included many code changes because I'm trying *not* to duplicate bug fixes Larry may already have applied. Here's an older description I prepared that's still mostly accurate: I've also included a few portability fixes in the main source, but these are certainly not a complete set of everything that's been reported. Don't be put off by the size of the patch. Mostly, it's just rearrangement of the parts in Configure and some cosmetic changes. Since gcc often supports long long, I had started to add quad support to Configure. Since SunOS 4.1.3 defines a conflicting "quad" structure, I changed the name from 'quad' to Quad_t, consistent with other Configure "types." I also changed "QUAD" to "HAS_QUAD". However, it turns out it's pretty hard to actually *use* Quad_t. Neither system I have access to can sprintf() a "long long", nor can they carry one around in an IV, unless I make IV "long long", which I didn't want to force generally. Thus I wonder whether any but a precious few could actually use Quad_t, and dropped the tests from Configure. I left in the s/quad/Quad_t/ and s/QUAD/HAS_QUAD/ stuff in case someone else wants to pick it up, and also because I was too lazy to take it back out :-). Some highlights: Configure Several new options. Use Configure -h to learn more. Also, read the directions Configure prints. :-) Spaces now allowed in -D command line options. New -O option that overrides config.sh. You can start interactively and then change that to accepting all the defaults by specifying &-d at any Configure prompt. This is useful if you have to re-run Configure to only change a few settings. Signal type set correctly for the cast{i32,neg} tests. archname detection improved a bit guard against ksh users who have set -u Oldconfig.U cleaned up and regularized a bit more. Guard against hint files using (and over-writing) $tmp. Command line options now are processed after metaconfig INIT lines. Thus things like Configure -Uuseposix should work now. Various miscellaneous clean-ups. better use/detection of tr. i_db.U now checks for hash and prefix type (I think!) I can't test it here. i_?db*.U now all check for an associated function before deciding to include or not the header. MANIFEST MANIFEST.new Sorted & updated. Makefile.SH Some shells/makes bombed out on test -d lib/auto || mkdir lib/auto Use makedir instead. README Some additional notes that people won't read :-). cflags.SH Now calls $startsh. Weird things were happening on Intergraph, and this might be related. config.H Updated. config_h.SH Regenerated. deb.c Varargs dependencies on STANDARD_C replaced by I_STDARG. doop.c quad stuff. ext/DB_File/DB_File.xs Use the new DB_Hash_t and DB_Prefix_t symbols. ext/SDBM_File/sdbm/sdbm.h Fix #defines to be more robust. mg.c Replace VOIDSIG by metaconfig's Signal_t. opcode.h opcode.pl semop only takes 2 arguments, not 3. perl.c Better guard on getenv() prototype. A hint file can use this, if necessary. Me, I think some compilers are just too picky. perl.h The (very) beginnings of some Quad support. See above. Remove the very troublesome sprintf() prototype. Since we don't _use_ the return value anyway (since it's not portable) this should be o.k. The problem was that some systems CAN_PROTOTYPE but include char *sprintf(); in <stdio.h>. That's incompatible with the version we used to have in perl.h. Most people have a prototype for sprintf() in <stdio.h>. Those that don't probably can get by without it anyway. Protect the timesbuf by the specific HAS_TIMES test. Some older gcc-2.something/Solaris 2.something installations apparently don't have times. pp.c More quad stuff. pp_ctl.c s/STANDARD_C/I_STDARG/ for varargs stuff. pp_sys.c use Signal_t. proto.h Update to match new metaconfig names. util.c s/STANDARD_C/I_STDARG/ for varargs stuff. comment out <unistd.h>. A pause prototype was causing problems on some systems. vms/config.vms Changed to use Signal_t.

* perl 4.0 patch 11: (combined patch)Larry Wall1991-11-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Subject: added eval {} Subject: eval 'stuff' now optimized to eval {stuff} This set of patches doesn't have many enhancements but this is one of them. The eval operator has two distinct semantic functions. First, it runs the parser on some random string and executes it. Second, it traps exceptions and returns them in $@. There are times when you'd like to get the second function without the first. In order to do that, you can now eval a block of code, which is parsed like ordinary code at compile time, but which traps any run-time errors and returns them in the $@ variable. For instance, to trap divide by zero errors: eval { $answer = $foo / $bar; }; warn $@ if $@; Since single-quoted strings don't ever change, they are optimized to the eval {} form the first time they are encountered at run-time. This doesn't happen too often, though some of you have written things like eval '&try_this;'. However, the righthand side of s///e is evaluated as a single-quoted string, so this construct should run somewhat faster now. Subject: added sort {} LIST Another enhancement that some of you have been hankering for. You can now inline the sort subroutine as a block where the subroutine name used to go: @articles = sort {$a <=> $b;} readdir(DIR); Subject: added some support for 64-bit integers For Convexen and Crayen, which have 64-bit integers, there's now pack, unpack and sprintf support for 64-bit integers. Subject: sprintf() now supports any length of s field You can now use formats like %2048s and %-8192.8192s. Perl will totally bypass your system's sprintf() function on these. No, you still probably can't say %2048d. No, I'm not going to change that any time soon. Subject: substr() and vec() weren't allowed in an lvalue list Subject: extra comma at end of list is now allowed in more places (Hi, Felix!) Subject: underscore is now allowed within literal octal and hex numbers Various syntactic relaxations. You can now get away with (substr($foo,0,3), substr($bar,0,3)) = ('abc', 'def'); (1,2,3,)[$x]; $addr = 0x1a20_ff0b; Subject: safe malloc code now integrated into Perl's malloc when possible To save a bunch of subroutine calls. If you use your system's malloc it still has to use wrappers. Subject: added support for dbz By saying "make dbzperl" you can make a copy of Perl that can access C news's dbz files. You still have to follow the dbz rules, though, if you're going to try to write a dbz file. Subject: there are now subroutines for calling back from C into Perl Subject: usub/curses.mus now supports SysV curses More C linkage support. I still haven't got Perl embeddable, but we're getting there. That's too big an enhancement for this update, in which I've been trying to stick to bug fixes, with some success. Subject: prepared for ctype implementations that don't define isascii() A larger percentage of this update consists of code to do consistent ctype processing whether or not <ctype.h> is 8-bit clean. Subject: /$foo/o optimizer could access deallocated data Subject: certain optimizations of //g in array context returned too many values Subject: regexp with no parens in array context returned wacky $`, $& and $' Subject: $' not set right on some //g Subject: grep of a split lost its values Subject: # fields could write outside allocated memory Subject: length($x) was sometimes wrong for numeric $x Recently added or modified stuff that you kind of expect to be a bit flaky still. Well, I do... Subject: passing non-existend array elements to subrouting caused core dump Subject: "foo" x -1 dumped core Subject: truncate on a closed filehandle could dump Subject: a last statement outside any block caused occasional core dumps Subject: missing arguments caused core dump in -D8 code Subject: cacheout.pl could dump core from invalid comparison operator Subject: *foo = undef coredumped Subject: warn '-' x 10000 dumped core Subject: index("little", "longer string") could visit faraway places A bunch of natty little bugs that you wouldn't generally run into unless you're trying to be coy. Subject: hex() didn't understand leading 0x It wasn't documented that it should work, but oct() understands 0x, so why not hex()? I dunno... Subject: "foo\0" eq "foo" was sometimes optimized to true Subject: eval confused by string containing null Yet more holdovers from the time before Perl was 8-bit clean. Subject: foreach on null list could spring memory leak Subject: local(*FILEHANDLE) had a memory leak Kind of slow leaks, as leaks go. Still... Subject: minimum match length calculation in regexp is now cumulative More substitutions can be done in place now because Perl knows that patterns like in s/foo\s+bar/1234567/ have to match a certain number of characters total. It used to be on that particular pattern that it only knew that it had to match at least 3 characters. Now it know it has to match at least 7. Subject: multiple reallocations now avoided in 1 .. 100000 You still don't want to say 1 .. 1000000, but at least it will refrain from allocating intermediate sized blocks while it's constructing the value, and won't do the extra copies implied by realloc. Subject: indirect subroutine calls through magic vars (e.g. &$1) didn't work Subject: defined(&$foo) and undef(&$foo) didn't work Subject: certain perl errors should set EBADF so that $! looks better Subject: stats of _ forgot whether prior stat was actually lstat Subject: -T returned true on NFS directory Subject: sysread() in socket was substituting recv() Subject: formats didn't fill their fields as well as they could Subject: ^ fields chopped hyphens on line break Subject: -P didn't allow use of #elif or #undef Subject: $0 was being truncated at times Subject: forked exec on non-existent program now issues a warning Various things you'd expect to work the way you expect, but didn't when you did, or I did, or something... Subject: perl mistook some streams for sockets because they return mode 0 too Subject: reopening STDIN, STDOUT and STDERR failed on some machines Problems opening files portably. So what's new? Subject: cppstdin now installed outside of source directory Subject: installperl now overrides installer's umask People who used cppstdin for the cpp filter or who had their umask set to 700 will now be happier. (And Configure will now prefer /lib/cpp over cppstdin like it used to. If this gives your machine heartburn because /lib/cpp doesn't set the symbols it should, write a hints file to poke them into ccflags.) Subject: initial .* in pattern had dependency on value of $* An initial .* was optimized to have a ^ on the front to avoid retrying when we know it won't match. Unfortunately this implicit ^ was paying attention to $*, which it shouldn't have been. Subject: certain patterns made use of garbage pointers from uncleared memory Many of you saw this as a failure in t/op/pat.t. Subject: perl now issues warning if $SIG{'ALARM'} is referenced Since the book mentions "SIGALARM", I thought we needed this. Subject: solitary subroutine references no longer trigger typo warnings You can now use -w (more) profitably on programs that require other files. I figured if you mistype a subroutine name you'll get a fatal error anyway, unlike a variable, which just defaults to being undefined. Subject: $foo .= <BAR> could overrun malloced memory Good old-fashioned bug. Subject: \$ didn't always make it through double-quoter to regexp routines Subject: \x and \c were subject to double interpretation in regexps Subject: nested list operators could miscount parens Subject: sort eval "whatever" didn't work Syntactic misfeatures of various sorts. Subject: find2perl produced incorrect code for -group Subject: find2perl could be confused by names containing whitespace Subject: in a2p, split on whitespace produced extra null field Translator stuff.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Subject: Configure now handles defaults much better Subject: Configure now knows if config.sh was built on this machine Subject: Configure now checks file existence more efficiently Subject: Configure now handles stupid SCO csh Configure has been heavily revised. Many of the tests that used to simply force a decision now check that decision against the previous value of the variable, and offer to let you change it. The default now is to keep the old value, so that you don't lose information from your previous run. Because of this, it's now more important to know whether, in fact, config.sh was produced on this machine and on this version of the operating system. config.sh now contains a lastuname variable which contains the output of uname -a. If this matches the current output of uname -a, Configure defaults to including the old config.sh. Otherwise not. If there is no valid config.sh, then Configure looks defaults for the current architecture in the hints/ subdirectory instead. The guesswork I've done in this section of code is phenomenal, so you'll have to instruct me where I've misparsed the output of uname (a problem in portability all of its own). Subject: Configure now differentiates getgroups() type from getgid() type Subject: Configure now figures out malloc ptr type Subject: Configure now does better on sprintf() Configure was assuming that the array of values returned from getgroups was the same type as the gids returned by other system calls. Unfortunately, reality set in. Likewise for malloc() and sprintf(), which there is only one portable way to find out the return value of: try it one way or the other, and see if it blows up. Subject: C flags are now settable on a per-file basis Subject: reduced maximum branch distance in eval.c Certain compilers and/or optimizers get bozoed out by large compilation units, or by large structures within those units. Previously, you either had to change the compiler flags for all the files, or do hairy editing in Makefile.SH and remake the Makefile, necessitating a make depend. Now there is a script called cflags.SH whose duty it is to return the proper CFLAGS for any given C file. You can change the flags in just one spot now and they will be immediately reflected in the next make (or even in the current make, if one is running). Eventually I expect that any of the hints files could modify cflags.SH, but I haven't done that yet. The particular problem of long jump offsets in eval.c has been at least partially alleviated by locating some of the labels in the middle of the function instead of at the end. This still doesn't help the poor Vax when you compile with -g, since it puts a jump to the end of the function to allocate the stack frame and then jumps back to the beginning of the function to execute it. For now Vaxen will have to stick with -O or hand assemble eval.c and teval.c with a -J switch. Subject: fixed "Bad free" error Subject: fixed debugger coredump on subroutines Subject: regexec only allocated space for 9 subexpresssions These are problems that were reported on the net and had unofficial patches. Now they have official patches. Be sure to patch a copy of your files without the unofficial patches, or the patch program will get confused. Subject: you may now use "die" and "caller" in a signal handler Someone pointed out that using die to raise an exception out of a signal handler trashed the expression value stack if the exception was caught by eval. While fixing that, I also fixed the longstanding problem that signal handlers didn't have a normal call frame, which prevented the caller function from working. Subject: fixed undefined environ problem Subject: hopefully straightened out some of the Xenix mess Subject: random cleanup in cpp namespace Just keeping up with the current progress in non-standardization. Subject: fixed failed fork to return undef as documented The open function returns undef on failed implicit forks. The Book assumed that the same was true of an explicit fork. I've made the function behave like the Book says. It's a pity there's no way to have an undefined value that returns -1 in a numeric context but false in a boolean context... Subject: generalized the yaccpar fixer some Thanks to Andy Dougherty, perly.fixer now knows how to fix SVR3 2.2's yaccpar code to do dynamic parse stack allocation. He also made it easy for other people to insert their code there. Hooray! Subject: find2perl sometimes needs to stat on the 2nd leg of a -o Subject: find2perl didn't correctly handle switches with an argument of 0 In attempting to delay the lstat to the last moment, in case a filename could be rejected on the basis of its name, find2perl neglected to take into account the fact that control might pass to the 2nd half of a -o without executing all of the 1st half, in particular without executing the lstat. find2perl was wisely removing leading zeroes from numbers that would mistakenly be interpreted as octal numbers by Perl. Unfortunately, this caused it to delete the number 0 entirely. Subject: fixed dumpvar not to dump internal debugging info Subject: substr($ENV{"PATH"},0,0) = "/foo:" didn't modify environment Subject: $foo .= <BAR> could cause core dump for certain lengths of $foo Subject: perl -de "print" wouldn't stop at the first statement Random glitchy little things. Subject: I'm at NetLabs now I'm now working for NetLabs, Inc., and I hadn't changed my address everywhere.
* perl 4.0.00: (no release announcement available)perl-4.0.00Larry Wall1991-03-211-8/+16
| | | | So far, 4.0 is still a beta test version. For the last production version, look in pub/perl.3.0/kits@44.
* perl 3.0 patch #42 (combined patch)Larry Wall1991-01-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of these patches are pretty self-explanatory. Much of this is random cleanup in preparation for version 4.0, so I won't talk about it here. A couple of things should be noted, however. First, there's a new -0 option that allows you to specify (in octal) the initial value of $/, the record separator. It's primarily intended for use with versions of find that support -print0 to delimit filenames with nulls, but it's more general than that: null ^A default CR paragraph mode file slurp mode This feature is so new that it didn't even make it into the book. The other major item is that different patchlevels of perl can now coexist in your bin directory. The names "perl" and "taintperl" are just links to "perl3.044" and "tperl3.044". This has several benefits. The perl3.044 invokes the corresponding tperl3.044 rather than taintperl, so it always runs the correct version. Second, you can "freeze" a script by putting a #! line referring to a version that it is known to work with. Third, you can put a new version out there to try out before making it the default perl. Lastly, it sells more disk drives. :-) Barring catastrophe, this will likely be the last patch before version 4.0 comes out.
* perl 3.0 patch #41 (combined patch)Larry Wall1990-11-131-0/+1
| | | | | | | | | | | | | | | | Here's the requisite dinky patch to fix the problems of the preceding large set of patches. In this case, a couple of malloc/free problems--one of which involved overrunning the end of an allocated string, and the other of which involved freeing with invalid pointers. (There was also a bug in there involving variable magicalness propagating incorrectly, which resulting in a dbm anomoly.) I updated README to mention that dnix needs to avoid -O. I added the hp malloc union overhead strut that Jan Dr{rv posted. (Eventually this should be determined by Configure, but laziness has its advantages.)
* perl 3.0 patch #38 (combined patch)Larry Wall1990-11-091-1/+5
| | | | Forget the description, it's too late at night...
* perl 3.0 patch #37 (combined patch)Larry Wall1990-10-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | I tried to take the strlen of an integer on systems without wait4() or waitpid(). For some reason this didn't work too well... In hash.c there was a call to dbm_nextkey() which needed to be ifdefed on old dbm systems. A pattern such as /foo.*bar$/ was wrongly optimized to do tail matching on "foo". This was a longstanding bug that was unmasked by patch 36. Some systems have some SYS V IPC but not all of it. Configure now figures this out. Patch 36 put the user's PATH in front of Configures, but to make it work right I needed to change all calls of loc to ./loc in Configure. $cryptlib needed to be mentioned in the Makefile. Apollo 10.3 and Sun 3.5 have some compilation problems, so I mentioned them in README. Cray has weird restrictions on setjmp locations--you can't say if (result = setjmp(...)) Random typos and cleanup.
* perl 3.0 patch #29 (combined patch)Larry Wall1990-10-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This set of patches pretty much brings you up to the functionality that version 4.0 will have. The Perl Book documents version 4.0. Perhaps these should be called release notes... :-) Enhancements: Many of the changes relate to making the debugger work better. It now runs your scripts at nearly full speed because it no longer calls a subroutine on every statement. The debugger now doesn't get confused about packages, evals and other filenames. More variables (though still not all) are available within the debugger. Related to this is the fact that every statement now knows which package and filename it was compiled in, so package semantics are now much more straightforward. Every variable also knows which package it was compiled in. So many places that used to print out just the variable name now prefix the variable name with the package name. Notably, if you print *foo it now gives *package'foo. Along with these, there is now a "caller" function which returns the context of the current subroutine call. See the man page for more details. Chip Salzenberg sent the patches for System V IPC (msg, sem and shm) so I dropped them in. There was no way to wait for a specific pid, which was silly, since Perl was already keeping track of the information. So I added the waitpid() call, which uses Unix's wait4() or waitpid() if available, and otherwise emulates them (at least as far as letting you wait for a particular pid--it doesn't emulate non-blocking wait). For use in sorting routines, there are now two new operators, cmp and <=>. These do string and numeric comparison, returning -1, 0 or 1 when the first argument is less than, equal to or greater than the second argument. Occasionally one finds that one wants to evaluate an operator in a scalar context, even though it's part of a LIST. For this purpose, there is now a scalar() operator. For instance, the approved fix for the novice error of using <> in assigning to a local is now: local($var) = scalar(<STDIN>); Perl's ordinary I/O is done using standard I/O routines. Every now and then this gets in your way. You may now access the system calls read() and write() via the Perl functions sysread() and syswrite(). They should not be intermixed with ordinary I/O calls unless you know what you're doing. Along with this, both the sysread() and read() functions allow you an optional 4th argument giving an offset into the string you're reading into, so for instance you can easily finish up partial reads. As a bit of syntactic sugar, you can now use the file tests -M, -A and -C to determine the age of a file in (possibly fractional) days as of the time the script started running. This makes it much easier to write midnight cleanup scripts with precision. The index() and rindex() functions now have an optional 3rd argument which tells it where to start looking, so you can now iterate through a string using these functions. The substr() function's 3rd argument is now optional, and if omitted, the function returns everything to the end of the string. The tr/// translation function now understands c, d and s options, just like the tr program. (Well, almost just like. The d option only deletes characters that aren't in the replacement string.) The c complementes the character class to match and the s option squishes out multiple occurrences of any replacement class characters. The reverse function, used in a scalar context, now reverses its scalar argument as a string. Dale Worley posted a patch to add @###.## type fields to formats. I said, "Neat!" and dropped it in, lock, stock and sinker. Kai Uwe Rommel sent a bunch of MSDOS and OS/2 updates, which I (mostly) incorporated. I can't vouch for them, but they look okay. Any data stored after the __END__ marker can be accesses now via the DATA filehandle, which is automatically opened onto the script at that point. (Well, actually, it's just kept open, since it was already open to read the script.) The taintperl program now checks for world writable PATH components, and complains if any are found (if PATH is used). Bug fixes: It used to be that you could get core dumps by such means as @$foo=(); @foo[42]; (1,2,3)[42]; $#foo = 50; foreach $elem (@foo) { $elem = 1; } This is no longer so. (For those who are up on Perl internals, the stack policy no longer allows Nullstr--all undefined values must be passed as &str_undef.) If you say something like local($foo,$bar); or local($initialized,$foo,$bar) = ('one value'); $foo and $bar are now initialized to the undefined value, rather than the defined null string. Array assignment to special arrays is now better supported. For instance, @ENV = () clears the environment, and %foo = () will now clear any dbm file bound to %foo. On the subject of dbm files, the highly visible bugs at patchlevel 28 have been fixed. You can now open dbm files readonly, and you don't have to do a dummy assignment to make the cache allocate itself. The modulus operator wasn't working right on negative values because of a misplaced cast. For instance, -5 % 5 was returning the value 5, which is clearly wrong. Certain operations coredumped if you didn't supply a value: close; eof; Previously, if the subroutine supplied for a sort operation didn't exist, it failed quietly. Now it produces a fatal error. The bitwise complement operator ~ didn't work on vec() strings longer than one byte because of failure to increment a loop variable. The oct and hex functions returned a negative result if the highest bit was set. They now return an unsigned result, which seems a little less confusing. Likewise, the token 0x80000000 also produces an unsigned value now. Some machines didn't like to see 0x87654321 in an #ifdef because they think of the symbols as signed. The tests have been changed to just look at the lower 4 nybbles of the value, which is sufficient to determine endianness, at least as far as the #ifdefs are concerned. The unshift operator did not return the documented value, which was the number of elements in the new array. Instead it returned the last unshifted argument, more or less by accident. -w sometimes printed spurious warnings about ARGV and ENV when referencing the arrays indirectly through shift or exec. This was because the typo test was misplaced before the code that exempts special variables from the typo test. If you said 'require "./foo.pl"', it would look in someplace like /usr/local/lib/perl/./foo.pl instead of the current directory. This works more like people expect now. The require error messages also referred to wrong file, if they worked at all. The h2ph program didn't translate includes right--it should have changed .h to .ph. Patterns with multiple short literal strings sometimes failed. This was a problem with the code that looks for a maximal literal string to feed to the Boyer-Moore searching routine. The code was gluing together literal strings that weren't continuous. The $* variable controls multi-line pattern matching. When it's 0, patterns are supposed to match as if the string contained a single line. Unfortunately, /^pat/ occasionally matched in middle of string under certain conditions. Recently the regular expression routines were upgraded to do {n,m} more efficiently. In doing this, however, I manufactured a couple of bugs: /.{n,m}$/ could match with fewer than n characters remaining on the line, and patterns like /\d{9}/ could match more than 9 characters. The undefined value has an actual physical location in Perl, and pointers to it are passed around. By certain circuitous routes it was possible to clobber the undefined value so that it was no longer undefined--kind of like making /dev/null into a real file. Hopefully this can't happen any more. op.stat could fail if /bin/0 existed, because of a while (<*>) {... This has been changed to a while (defined($_ = <*>)) {... The length of a search pattern was limited by the length of tokenbuf internally. This restriction has been removed. The null character gave the tokener indigestion when used as a delimiter for m// or s///. There was a bunch of other cleanupish things that are too trivial to mention here.

See the files in usub/ for an example. There is now an operator to include library modules with duplicate suppression and error checking, called "require". (makelib has been renamed to h2ph, and Tom Christiansen's h2pl stuff has been included too. Perl .h files are now called .ph files to avoid confusion.) It's now possible to truncate files if your machines supports any of ftruncate(fd, size), chsize(fd, size) or fcntl(fd, F_FREESP, size). Added -c switch to do compilation only, that is, to suppress execution. Useful in combination with -D1024. There's now a -x switch to extract a script from the input stream so you can pipe articles containing Perl scripts directly into perl. Previously, the only places you could use bare words in Perl were as filehandles or labels. You can now put bare words (identifiers) anywhere. If they have no interpretation as filehandles or labels, they will be treated as if they had single quotes around them. This works together nicely with the fact that you can use a symbol name indirectly as a filehandle or to assign to *name. It basically means you can write subroutines and pass filehandles without quoting or *-ing them. (It also means the grammar is even more ambiguous now--59 reduce/reduce conflicts!!! But it seems to do the Right Thing.) Added __LINE__ and __FILE__ tokens to let you interpolate the current line number or filename, such as in a call to an error routine, or to help you translate eval linenumbers to real linenumbers. Added __END__ token to let you mark the end of the program in the input stream. (^D and ^Z are allowed synonyms.) Program text and data can now both come from STDIN. `command` in array context now returns array of lines. Previously it would return a single element array holding all the lines. An empty %array now returns 0 in scalar context so that you can use it profitably in a conditional: &blurfl if %seen; The include search path (@INC) now includes . explicity at the end, so you can change it if you wish. Library routines now have precedence by default. Several pattern matching optimizations: I sped up /x+y/ patterns greatly by not retrying on every x, and disabled backoff on patterns anchored to the end like /\s+$/. This made /\s+$/ run 100 times faster on a string containing 70 spaces followed by an X. Actual improvements will generally be less than that. I also sped up {m,n} on simple items by making it a variant of *. And /.*whatever/ is now optimizaed to /^.*whatever/ to avoid retrying at every position in the event of failure. I fixed character classes to allow backslashing hyphen, by popular request. In the past, $ in a pattern would sometimes match in the middle of the string and sometimes not, if $* == 0. Now it will never match except at the end of the string, or just before a terminating newline. When $* == 1 behavior is as before. In the README file, I've expanded on just how I think the GNU General Public License applies to Perl and to things you might want to do with Perl. The interpreter used to set the global variable "line" to be the current line number. Instead, it now sets a global pointer to the current Perl statement, which is no more overhead, but now we will have access to the file name and package name associated with that statement, so that the debugger soon be upgraded to allow debugging of evals and packages. In the past, a conditional construct in an array context passed the array context on to the conditional expression, causing general consternation and confusion. Conditionals now always supply a scalar context to the expression, and if that expression turns out to be the one whose value is returned, the value is coerced to an array value of one element. The switch optimizer was confused by negative fractional values, and truncating them the wrong direction. Configure now checks for chsize, select and truncate functions, and now asks if you want to put scripts into some separate directory from your binaries. More and more people are establishing a common directory across architectures for scripts, so this is getting important. It used to be that a numeric literal ended up being stored both as a string and as a double. This could make for lots of wasted storage if you said things like "$seen{$key} = 1;". So now numeric literals are now stored only in floating point format, which saves space, and generates at most one extra conversion per literal over the life of the script. The % operator had an off-by-one error if the left argument was negative. The pack and unpack functions have been upgraded. You can now convert native float and double fields using f and d. You can specify negative relative positions with X<n>, and absolute positions in the record with @<n>. You can have a length of * on the final field to indicate that it is to gobble all the rest of the available fields. In unpack, if you precede a field spec with %<n>, it does an n-bit checksum on it instead of the value itself. (Thus "%16C*" will checksum just like the Sys V sum program.) One totally wacked out evening I hacked a u format in to pack and unpack uudecode-style strings. A couple bugs were fixed in unpack--it couldn't unpack an A or a format field in a scalar context, which is just supposed to return the first field. The c and C formats were also calling bcopy to copy each character. Yuck. Machines without the setreuid() system call couldn't manipulate $< and $> easily. Now, if you've got setuid(), you can say $< = $> or $> = $< or even ($<, $>) = ($uid, $uid), as long as it's something that can be done with setuid(). Similarly for setgid(). I've included various MSDOS and OS/2 patches that people have sent. There's still more in the hopper... An open on a pipe for output such as 'open(STDOUT,"|command")' left STDOUT attached to the wrong file descriptor. This didn't matter within Perl, but it made subprocesses expecting stdout to be on fd 1 rather irate. The print command could fail to detect errors such as running out room on the disk. Now it checks a little better. Saying "print @foo" might only print out some of the elements if there undefined elements in the middle of the array, due to a reversed bit of logic in the print routine. On machines with vfork the child process would allocate memory in the parent without the parent knowing about it, or having any way to free the memory so allocated. The parent now calls a cleanup routine that knows whether that's what happened. If the getsockname or getpeername functions returned a normal Unix error, perl -w would report that you tried I/O on an unopened socket, even though it was open. MACH doesn't have seekdir or telldir. Who ever uses them anyway? Under certain circumstances, an optimized pattern match could pass a hint into the standard pattern matching routine which the standard routine would then ignore. The next pattern match after that would then get a "panic: hint in do_match" because the hint didn't point into the current string of interest. The $' variable returned a short string if it contained an embedded null. Two common split cases are now special-cased to avoid the regular expression code. One is /\s+/ (and its cousin ' ', which also trims leading whitespace). The other is /^/, which is very useful for splitting a "here-is" quote into lines: @lines = split(/^/, <<END); Element 0 Element 1 Element 2 END You couldn't split on a single case-insensitive letter because the single character split optimization ignore the case folding flag. Sort now handles undefined strings right, and sorts lists a little more efficiently because it weeds them out before sorting so it doesn't have to check for them on every comparison. The each() and keys() functions were returning garbage on null keys in DBM files because the DBM iterator merely returns a pointer into the buffer to a string that's not necessarily null terminated. Internally, Perl keeps a null at the end of every string (though allowing embedded nulls) and some routines make use of this to avoid checking for the end of buffer on every comparison. So this just needed to be treated as a special case. The &, | and ^ operators will do bitwise operations on two strings, but for some reason I hadn't implemented ~ to do a complement. Using an associative array name with a % in dbmopen(%name...) didn't work right, not because it didn't parse, but because the dbm opening routine internally did the wrong thing with it. You can now say dbmopen(name, 'filename', undef) to prevent it from opening the dbm file if it doesn't exist. The die operator simply exited if you didn't give an argument, because that made sense before eval existed. But now it will be equivalent to "die 'Died';". Using the return function outside a subroutine returned a cryptic message about not being able to pop a magical label off the stack. It's now more informative. On systems without the rename() system call, it's emulated with unlink()/link()/unlink(), which could clobber a file if it happened to unlink it before it linked it. Perl now checks to make sure the source and destination filenames aren't in fact the same directory entry. The -s file test now returns size of file. Why not? If you tried to write a general subroutine to open files, passing in the filehandle as *filehandle, it didn't work because nobody took responsibility to allocate the filehandle structure internally. Now, passing *name to subroutine forces filehandle and array creation on that symbol if they're already not created. Reading input via <HANDLE> is now a little more efficient--it does one less string copy. The dumpvar.pl routine now fixes weird chars to be printable, and allows you to specify a list of varables to display. The debugger takes advantage of this. The debugger also now allows \ continuation lines, and has an = command to let you make aliases easily. Line numbers should now be correct even after lines containing only a semicolon. The action code for parsing split; with no arguments didn't pass correct a corrent value of bufend to the scanpat it was using to establish the /\s+/ pattern. The $] variable returned the rcsid string and patchlevel. It still returns that in a string context, but in a numeric context it returns the version number (as in 4.0) + patchlevel / 1000. So these patches are being applied to 3.018. The variables $0, %ENV, @ARGV were retaining incorrect information from the previous incarnation in dumped/undumped scripts. The %ENV array is suppose to be global even inside packages, but and off-by-one error kept it from being so. The $| variable couldn't be set on a filehandle before the file was opened. Now you can. If errno == 0, the $! variable returned "Error 0" in a string context, which is, unfortunately, a true string. It now returns "" in string context if errno == 0, so you can use it reasonable in a conditional without comparing it to 0: &cleanup if $!; On some machines, conversion of a number to a string caused a malloc string to be overrun by 1 character. More memory is now allocated for such a string. The tainting mechanism didn't work right on scripts that were setgid but not setuid. If you had reference to an array such as @name in a program, but didn't invoke any of the usual array operations, the array never got initialized. The FPS compiler doesn't do default in a switch very well if the value can be interpreted as a signed character. There's now a #ifdef BADSWITCH for such machines. Certain combinations of backslashed backslashes weren't correctly parsed inside double-quoted strings. "Here" strings caused warnings about uninitialized variables because the string used internally to accumulate the lines wasn't initialized according to the standards of the -w switch. The a2p translator couldn't parse {foo = (bar == 123)} due to a hangover from the old awk syntax. It also needed to put a chop into a program if the program referenced NF so that the field count would come out right when the split was done. There was a missing semicolon when local($_) was emitted. I also didn't realize that an explicity awk split on ' ' trims leading whitespace just like the implicit split at the beginning of the loop. The awk for..in loop has to be translated in one of two ways in a2p, depending on whether the array was produced by a split or by subscripting. If the array was a normal array, a2p put out code that iterated over the array values rather than the numeric indexes, which was wrong. The s2p didn't translate \n correctly, stripping the backslash.

Special thanks go to Diomidis Spinellis <dds@cc.ic.ac.uk> for this. To compile under MSDOS, look at the readme file in the msdos subdirectory. As a part of this, six files will be renamed when you run Configure. These are config.h.SH, perl.man.[1-4] and t/op.subst. Suns (and perhaps other machines) can't cast negative floating point numbers to unsigned ints reasonably. Configure now detects this and takes appropriate action. Configure looked for optional libraries but then didn't ever use them, even if there was no config.sh value to override. System V Release 4 provides us with yet another nm format for Configure to parse. No doubt it's "better". Sigh. MIPS CPUs running under Ultrix were getting configured for volatile support, but they don't like volatile when applied to a type generated by a typedef. Configure now tests for this. I've added two new perl library routines: ctime.pl from Waldemar Kebsch and Marion Hakanson, and syslog.pl from Tom Christiansen and me. In subroutines, non-terminal blocks should never have arrays requested of them, even if the subroutine call's context is looking for an array. Formats didn't work inside eval. Now they do. Any $foo++ that doesn't return a value is now optimized to ++$foo since the latter doesn't require generation of a temporary to hold the old value. A self-referential printf pattern such as sprintf($s,...,$s,...) would end up with a null as the first character of the next field. On machines that don't support executing scripts in the kernel, perl has to emulate that when an exec fails. In this case, the do_exec() routine can lose arguments passed to the script. A memory leakage in pattern matching triggered by use of $`, $& or $' has been fixed. A splice that pulls up the front of an array such as splice(@array,0,$n) can cause a duplicate free error. The grep operator blew up on undefined array values. It now handles them reasonably, setting $_ to undef. The .. operator in an array context is used to generate number ranges. This has been generalized to allow any string ranges that can be generated with the magical increment code of ++. So you can say 'a' .. 'f', '000'..'999', etc. The ioctl function didn't return non-zero values correctly. Associative array slices from dbm files like @dbmvalues{'foo','bar'} could use the same cache entry for multiple values, causing loss of some of the values of the slice. Cache values are now not flushed until the end of a statement. The do FILE operator blew up when used inside an eval, due to trying to free the eval code it was still executing. If you did s/^prefix// on a string, and subsequently assigned a value that didn't contain a string value to the string, you could get a bad free error. One of the taint checks blew up on undefined array elements, which showed up only when taintperl was run. The final semicolon in program is supposed to be optional now. Unfortunately this wasn't true when -p or -n added extra code around your code. Now it's true all the time. A tail anchored pattern such as /foo$/ could cause grief if you searched a string that was shorter than that.
