This Week on perl5-porters (Oct 04-10 2004) Crosscompiling perl Alexander Povolotsky, lacking a native compiler on Linux PPC, tried to crosscompile from Cygwin (Intel). Many people admonished that while crosscompiling perl is possible in principle, there's little support for it, so getting the native compiler in place would probably be easier.

[Please correct this explanation if necessary.] http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-10/msg00065.html Smoke failing on FreeBSD Abe Timmerman's new smoke machine, a FreeBSD-running sparc64, failed with what might be an integer-size configuration problem. http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-10/msg00071.html Weird results from hash assignment with duplicate keys Boris Zentner, trying to remove duplicate hash values %h = reverse (%x = reverse %h); discovered a fascinating bug (#31865) in assigning duplicate keys to a hash, pinpointed by Rick Delaney (and Devel::Peeked by Graham Barr): $ perl5.8.3 -le 'print (%x = ("a",1,"b",2,"b",3));' bb $ perl5.6.1 -le 'print (%x = ("a",1,"b",2,"b",3));' a1bb3 (should be 'a1b3'). http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-10/msg00073.html Making regcomp a list op Dave Mitchell set the stage for fixing the behaviors of "(?{...})" and regex objects, by making "regcomp" receive the components of run-time regexes ($a, '-', $b in "/$a-$b/") as a list rather than a concatenation of the components. Commentators oohed and aahed as the chessmaster advanced his pawn. [If you're an internals novice like me, try understanding Dave's before and after "B::Concise" output, using "B::Concise" (what do the flags mean?), "perlguts" (the "Compiled code" section), and "perlcall" (what's a "PUSHMARK"?).] http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-10/msg00132.html IO::Poll undef fd unchecked in mask method Peter Dintelmann found a problem (bug #31864) in "IO::Poll", where its "mask" method incorrectly evaluated an "undef" argument as 0 (STDIN). http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-10/msg00072.html Dynaloader improvements and cleanup Vadim Konovalov continued his Dynaloader patching from the previous week, and while he was at it enabled statically linked extensions for Win32. More fixes to come. http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-10/msg00034.html http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-10/msg00126.html Releases Encode 2.03 - Dan Kogai Module::Build 0.26 - Ken Williams Random quote From Dave Mitchell's sig: Any [programming] language that doesn't occasionally surprise the novice will pay for it by continually surprising the expert. -- Larry Wall Reference The thread for bug number $BUGNUM can be found at http://rt.perl.org/rt3/Ticket/Display.html?id=$BUGNUM About this summary This summary was written by Scott Lanning.
