Maintaining Perl 5: Grant Report for Month 11

No Comments

Tony Cook writes:

Approximately 63 tickets were reviewed or worked on, and 10 patches were applied.

Probably the most interesting task this month was attempting to optimize regen/regcharclass.pl which became noticably slower when extra EBCDIC code pages were added to the build. Two fairly simple optimizations fell out of the profile from Devel::NYTProf.

get_a2n() and get_I8_2_utf() were each called over 150,000 times, and returned their mappings as a list, while in most cases only a small part of the mapping was used. I changed these return an array reference instead, speeding up regcharclass.pl significantly.
