Date: Wed, 20 Nov 96 14:04:08 GMT
From: Paul Marquess <pmarquess@bfsec.bt.co.uk>
Files: pod/perlfunc.pod

    Following on from the patch to make uc, lc etc default to $_ (as per
    Camel II), here is a followup patch to perlfunc that documents the
    change. I think I have documented all the other cases where $_
    defaulting works as well.

Subject: Properly prototype safe{malloc,calloc,realloc,free}.

Files: proto.h

Subject: UnixWare 2.1 fix for perl5.003_08 - cope with fp->_cnt < -1, allow debugging
Date: Wed, 20 Nov 1996 14:27:06 +0100
From: John Hughes <john@AtlanTech.COM>
Files: sv.c

    UnixWare 2.1 has no fp->_base so most of the debugging stuff in sv_gets just
    core dumps.
    
    Also, for some unknown reason fp->_cnt is sometimes < -1, screwing up the
    initial SvGROW in svgets.
    
    Appart from that its io is std.

    Since _09 is going to be alpha anyway, I reiterate my question:
    	Is there any reason to not include my hash/array performance
    		patches in _09?
    
    Btw, here is the next performance patch. It makes PADTMP values
    stealable too. I do not do by setting TEMP flags on them, since it
    would be a very distributed patch, and it would break some places
    which check for TEMP for some other reasons (yes, I checked ;-).
    
    This patch decreases *twice* the memory usage of
    	perl -e '$a = "a" x 1e6; 1'
    
    Enjoy,

 PORTABILITY

Subject: VMS patches post-5.003_08
Date: Fri, 22 Nov 1996 18:16:31 -0500 (EST)
From: Charles Bailey <bailey@hmivax.humgen.upenn.edu>
Files: lib/ExtUtils/MM_Unix.pm lib/ExtUtils/MM_VMS.pm lib/ExtUtils/MakeMaker.pm lib/File/Path.pm mg.c pp_ctl.c utils/h2xs.PL vms/config.vms vms/descrip.mms vms/gen_shrfls.pl vms/genconfig.pl vms/perlvms.pod vms/vms.c vms/vmsish.h

    Here're diffs to bring a base 5.003_08 up to the current VMS working
    sources.  Nearly all of the changes are VMS-specific, and comprise
    miscellaneous bugfixes accumulated since 5.003_07, rather than any
    particular problem with 5.003_08.  I'm posting them here since some
    of the patches change core files, and I'd like to insure that I
    haven't accidentally created problems for anyone else.
    
    With these and a couple of of the small patches already send to p5p,
    5.003_08 builds clean and passes all tests under VMS.
    
    Thanks, Chip, for all the work.
