This Week on perl5-porters (Nov 01-09 2004) Tests failing when core extensions not built It's possible to configure perl without some built-in extensions, and this causes some tests to fail, so Nicholas was wondering about determining which extensions aren't enabled and skipping the corresponding tests.
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-10/msg00637.html Detecting strlcat() and strlcpy() in Configure H. Merijn Brand continued working on detecting these functions, which are safer versions of "strncat" and "strncpy". Craig Berry made it work on VMS. Adding the detection to Configure makes it easier for module writers to know if the functions are available. http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-10/msg00613.html Cwd test failing Yitzchak Scott-Thoennes reported (bug #32272) this test failure, which was later found to be ignorable. Yitzchak also mentioned that "Cwd" and "File::Spec" have been repackaged as "PathTools". http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-11/msg00065.html getXXXent functions break after recursing to grow buffer Bug #32154, apparently caused by RedHat's patched glibc, as it didn't show up in other distributions. http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-10/msg00573.html Nicholas incidentally pointed out that source code is available directly ftp://ftp.linux.activestate.com/pub/staff/gsar/APC/perl-5.8.x/ ftp://ftp.linux.activestate.com/pub/staff/gsar/APC/perl-current/ and a repository browser is at http://public.activestate.com/cgi-bin/perlbrowse Roadmap for 5.10 Rafael listed points in the roadmap for 5.10. Michael Schwern added that "Module::Build" and "CPANPLUS" should be put into the core, and Randy Sims pointed out some work that needs done on "M::B" first. Also mentioned was incorporating a minimal subset of "Inline". http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-11/msg00115.html Peephole optimization Tassilo von Parseval is working on optionalizing the peephole optimizer. Rafael pointed out that the intent of this is to make sure that the optree produced by the compiler is correct, and Hugo added that it could also be used for avoiding certain optimizations and allowing other aggressive optimizations. http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-11/msg00150.html Tassilo investigated further which peephole optimizations are currently mandatory for tests to pass. Jim Cromie suggested that he mess with "B::Generate" and "optimizer", which are in need of work. http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-11/msg00185.html Undefining signals Ben Morrow submitted, among other proposals, that $SIG{FOO} = undef; try to block the signal "FOO", then, failing that, "IGNORE" it. Nick Ing-Simmons brought up the problem of unmentioned signals being "undef", and the badness of blocking them (in particular, $SIG{INT}). http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-11/msg00234.html Sharing hash values Tels was dismayed by the inefficiency of the common "seen hash" idiom $seen{foo} = 1; if (exists $seen{foo}) { ... } Even using "undef" doesn't save much, so he wondered how he could share the undef for all the hash values. It turns out Gisle Aas has already done this with "Array::RefElem". Randy Sims suggested that we really want a set instead, for which Tels found "Set::Object". If you're like I was before doing the summaries, scanning for neat ideas, this thread is one you don't want to miss. http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2004-11/msg00288.html In brief Allen Smith successfully trolled with an "-ize" vs. "-ise" comment (actually I found the discussion interesting). Yitzchak Scott-Thoennes fixed "do "c:/foo.pl"" on Cygwin. David Nicol discussed writing a distributed (network) lock manager. Gisle Aas fixed a stack corruption in "Tk", which fixing filled H.Merijn Brand with joy. Jim Cromie continued work on optree tests, a problem with interleaving stdout and stderr on VMS and Cygwin. Steve Peters resuscitated at least 16 old bugs on RT, only to crush most of them beneath his shoe.
