Tie::DB_FileLock extends DB_File, providing a locking layer using flock(). Unlike Tie::DB_Lock, Tie::DB_FileLock does not duplicate files to allow concurrent access for readers and writers. Tie::DB_FileLock is therefore suitable for large dbms with relatively short locking periods.

Tie::Hash::Indexed is very similar to Tie::IxHash. However, it is written completely in XS and usually about twice as fast as Tie::IxHash. It's quite a lot faster when it comes to clearing or deleting entries from large hashes. Currently, only the plain tying mechanism is supported.

Tie::Hash::MultiValue allows you to have hashes which store their values in anonymous arrays, appending any new value to the already-existing ones. This means that you can store as many items as you like under a single key, and access them all at once by accessing the value stored under the key.

This package contains the following perl5 modules: * Time::CTime - ctime, strftime, and asctime * Time::JulianDay - Julian calendar manipulations * Time::ParseDate - reverses strftime and also understands relative times * Time::Timezone - miscellaneous timezone manipulations routines * Time::DaysInMonth - simply report the number of days in a month

This module allows you to compose Test::More tests from roles. It is inspired by the excellent Test::Routine module, but uses Moo instead of Moose. This gives most of the benefits without the need for Moose as a test dependency.

Text::Levenshtein implements the Levenshtein edit distance. The Levenshtein edit distance is a measure of the degree of proximity between two strings. This distance is the number of substitutions, deletions or insertions ("edits") needed to transform one string into the other one (and vice versa). When two strings have distance 0, they are the same.

Time::Duration::Parse is a module to parse human readable duration strings like 2 minutes and 3 seconds to seconds. It does the opposite of duration_exact function in Time::Duration and is roundtrip safe. So, the following is always true. use Time::Duration::Parse; use Time::Duration; my $seconds = int rand 100000; is( parse_duration(duration_exact($seconds)), $seconds );

UUID::Random::Patch::UseMRS makes UUID::Random use rand() from Math::Random::Secure instead of the default rand() that comes with Perl. It is useful for creating cryptographically secure UUID's. On the other hand, as a note, this makes generate() around 20 times slower. After you use this module, use UUID::Random as usual.

By default, variables are private to each thread, and each newly created thread gets a private copy of each existing variable. This module allows you to share variables across different threads (and pseudoforks on Win32). It is used together with the threads module.

PAPI aims to provide the tool designer and application engineer with a consistent interface and methodology for use of the performance counter hardware found in most major microprocessors. PAPI enables software engineers to see, in near real time, the relation between software performance and processor events.
