This Week on perl5-porters (22-28 December 2003)

Due to holidays, this was a low-traffic week. That's one more reason to get it delivered in time.

Math::BigInt

Tels pre-released Math::BigInt 1.68, with new stuff, refactorization, memory savings, and new method aliases to make the interface more consistent. He also posted some benchmarks.

Optimizations

Enache Adrian re-optimized the implementation of the string concatenation with lexical variables; the previous optimization has been disabled because it was buggy.

Windows breakages

According to bug report #24731, the implementation of fork() has problems under Windows 2003 64-Bit on Itanium 2. Unfortunately, we lack porters with access to this kind of machine.

Speaking about Windows, we seem to have lost threaded builds of perl 5.8.x on Windows, for an unknown reasons. Investigations to follow... (Obviously, perl 5.8.3 can't be shipped without this being fixed.)

Other bugs

Ton Hospel reports that undef used with the range operator in list context is treated as numerical 0, even for a magical string range. Rafael fixed this.

Jarkko Hietaniemi reports that this small code snippet :

    *foo{CODE} ? 1 : 0

is a syntax error in perl. It shouldn't be. Rafael fixed this.

Marcus Holland-Moritz thinks he hits a bug in a recent development snapshot of gcc 3.4, because a sprintf() test failing in perl's test suite. The bug in fact turns out to be an old bug in gcc's optimizer, and is trigerred with the -O3 level since gcc 3.4.
