Utilities
The utilities library (libkea-util) provides generic and Kea utilities:
- boost time: boost Posix time and duration to text conversions.
- buffer (header only): input and output buffers.
- csv file: comma-separated values (CSV) files.
- double: test utility for checking double equivalence (vs. strict equality).
- encode: base16, base32, base64 and hexadecimal conversions.
- filename: filename manipulation (avoid dependency on boost).
- hash: Fowler-Noll-Vo 64 bit hash function.
- io: test utils for file descriptors and sockets.
- io utilities (header only): reads and writes integers from / to buffers.
- labeled values: labeled constants and label constant sets.
- multi threading manager (in the util library to be available in the whole Kea code).
- optional: optional values.
- pid file: process id files.
- pointer util: test utility to compare smart pointers.
- process spawn.
- range utilities.
- read-write mutex (header only).
- signal set: signal handling (please use
isc::asiolink::IOSignalSet
instead).
- staged values.
- state model: event-driven deterministic finite state machine.
- stop watch: to measure code execution time.
- string util: various string common tools.
- thread pool.
- time utilities: DNSSEC time conversions from and to text.
- unittests (directory): tools for google test unit tests.
- unlock guard: RAII helper to unlock a mutex in a limited scope.
- versioned csv file: csv files with multiple versions of file schema.
- watched socket (required as select() or poll() do not support condition variables).
- watched threads: threads using ready, error and terminate watched socket.
Multi-Threading Consideration for Utilities
By default utilities are not thread safe, for instance CSV files and qid random generators are not thread safe. Exceptions are:
- multi threading manager is thread safe.
- read-write mutex is thread safe.
- state model is thread safe.
- thread pool is thread safe.
- unlock guard is thread safe.
- watched threads are thread safe.
