grep-2.18

[bdubbs@…]

We may or may not get this in before the package freeze. It depends on when 2.17 actualy gets released. Most changes have to do with multi-byte characters.

From the mailing list:

I would like to make a release in the next few days, so here is a snapshot of the latest. Please give it a spin.

Improvements

grep -i in a multibyte locale is now typically 10 times faster for patterns that do not contain \ or [.

grep (without -i) in a multibyte locale is now up to 7 times faster when processing many matched lines.

Range expressions in unibyte locales now ordinarily use the rational range interpretation, in which [a-z] matches only lower-case ASCII letters regardless of locale, and similarly for other ranges. (This was already true for multibyte locales.) Portable programs should continue to specify the C locale when using range expressions, since these expressions have unspecified behavior in non-GNU systems and are not yet guaranteed to use the rational range interpretation even in GNU systems.

Maintenance

grep's --mmap option was disabled in March of 2010, and began to elicit a warning in January of 2012. Now it is completely gone.
