use v5.14; use warnings; package Protocol::Sys::Virt v10.10.13; 1; =head1 NAME Protocol::Sys::Virt - Abstract LibVirt protocol implementation =head1 VERSION v10.10.13 Based on LibVirt tag v10.10.0 =head2 Version numbering The first two numbers follow the L release numbering (and thus API version); the last digit indicates the sequence number of releases of this library. =head1 SYNOPSIS =head1 DESCRIPTION This distribution implements the mechanics of the L protocol. With it, client and server components can be built, although it's unlikely anyone would want to build a LibVirt compatible server. Rationale behind the creation of this distribution is that it allows for the imlpementation of a truely asynchronous interface to LibVirt; a property L doesn't have, even when using its event loop integration. After having implemented L, the invocations to the methods in C turned out to be blocking regardless. The LibVirt development team explained this is by design. The solution in e.g. Python is to use threading (the same solution as used with Python): the underlying protocol and handling on the server is asynchronous, but the API calls are not. Unfortunately, in Perl, threading isn't a viable option: first of all because using Perl threads is highly discouraged, but more so because each thread creates its own Perl interpreter with its own copies of all variables -- a clear difference with Python, where a single interpreter is used for all threads, sharing variables and values. =head1 API Guarantees The LibVirt project describes the stability guarantees of the protocol at L. =head1 TODO =over 8 =item * Write documentation =back =head1 AUTHOR =over 8 =item * Erik Huelsmann C<< >> =back =head1 SEE ALSO L, L =head1 LICENSE AND COPYRIGHT Copyright (c) 2024, Erik Huelsmann C<< >>.
