  1. perl 4.0 patch 36: (combined patch)

    Larry Wall authored
    Since Ed Barton sent me a patch for the malignent form of "Malformed
    cmd links", I finally broke down and made a patch for the various
    other little things that have been accumulating on version 4.

  1. perl 4.0 patch 35: (combined patch)

    Larry Wall authored
    Subject: bad interaction between backslash and hyphen in tr///
    Among other things, tr/\040-\126/ / was not doing a character range,
    due to a earlier botched fix to make \- work right.
    
    Subject: Configure test for presence of nroff was wrong
    If Loc doesn't find nroff, it sets $nroff to 'nroff'.  The man
    page test was tesing against the null string.
    
    Subject: installperl error message printed file mode in decimal, not octal
    A real, honest-to-goodnes nit.
    
    Subject: fixed up some filenames in MANIFEST
    Erroneously contained "pstruct", omitted hints/isc_3_2_3.sh.

    Here's the typical cleanup patch that follows any large

  1. perl 4.0 patch 19: (combined patch)

    Larry Wall authored
    Ok, here's the cleanup patch I suggested you wait for.  Have at it...
    
    Subject: added little-endian pack/unpack options
    
    This is the only enhancement in this patch, but it seemed unlikely
    to bust anything else, and added functionality that it was very
    difficult to do any other way.  Compliments of David W. Sanderson.
    
    Subject: op/regexp.t failed from missing arg to bcmp()
    Subject: study was busted by 4.018
    Subject: sort $subname was busted by changes in 4.018
    Subject: default arg for shift was wrong after first subroutine definition
    
    Things that broke in 4.018.  Shame on me.
    
    Subject: do {$foo ne "bar";} returned wrong value
    
    A bug of long standing.  How come nobody saw this one?  Or if you
    did, why didn't you report it before now?  Or if you did, why did
    I ignore you?  :-)
    
    Subject: some machines need -lsocket before -lnsl
    Subject: some earlier patches weren't propagated to alternate 286 code
    Subject: compile in the x2p directory couldn't find cppstdin
    Subject: more hints for aix, isc, hp, sco, uts
    Subject: installperl no longer updates unchanged library files
    Subject: uts wrongly defines S_ISDIR() et al
    Subject: too many preprocessors can't expand a macro right in #if
    
    The usual pastiche of portability kludges.
    
    Subject: deleted some unused functions from usersub.c
    
    And fixed the spelling of John Macdonald's name, and included his
    suggested workaround for a certain vendor's stdio bug...
    
    Subject: added readdir test
    Subject: made op/groups.t more reliable
    Subject: added test for sort $subname to op/sort.t
    Subject: added some hacks to op/stat.t for weird filesystem architectures
    
    Improvements (hopefully) to the regression tests.

  8. perl 4.0 patch 11: (combined patch)

    Larry Wall authored
    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: new complete.pl from Wayne Thompson
    Subject: assert.pl and exceptions.pl from Tom Christiansen
    Subject: added Tom's c2ph stuff
    Subject: getcwd.pl from Brandon S. Allbery
    Subject: fastcwd.pl from John Basik
    Subject: chat2.pl from Randal L. Schwartz
    
    New contributed stuff.  Thanks!
    
    (Not that a lot of the other stuff isn't contributed too...)
    
    Subject: debugger got confused over nested subroutine definitions
