Dezvoltatorii platformei XCP-ng, care este dezvoltat\u0103 sub umbrela proiectului Xen, au publicat un plan de creare a unui \u00eenlocuitor pentru diverse componente ale stivei software Xen \u00een limbajul Rust. Hypervisorul Xen nu va fi ref\u0103cut deocamdat\u0103, iar munca se concentreaz\u0103 \u00een principal pe refacerea unor componente specifice ale setului de instrumente. <\/p>\n

\u00cen prezent, platforma utilizeaz\u0103 componente \u00een limbajele C, Python, OCaml \u0219i Go, dintre care unele sunt dep\u0103\u0219ite \u0219i provoac\u0103 probleme de \u00eentre\u021binere. Se observ\u0103 c\u0103 utilizarea Rust nu va duce la o cre\u0219tere general\u0103 a num\u0103rului de limbaje utilizate, deoarece \u00een Go este implementat\u0103 doar o component\u0103, care urmeaz\u0103 s\u0103 fie \u00eenlocuit\u0103 prima dat\u0103. <\/p>\n

Limba Rust a fost aleas\u0103 deoarece combin\u0103 o performan\u021b\u0103 \u00eenalt\u0103 a codului rezultat cu posibilit\u0103\u021bi pentru o gestionare sigur\u0103 a memoriei, f\u0103r\u0103 a necesita un colector de gunoi, fiind potrivit\u0103 pentru dezvoltarea at\u00e2t a componentelor de nivel inferior c\u00e2t \u0219i a celor de nivel superior, oferind posibilit\u0103\u021bi suplimentare de reducere a erorilor poten\u021biale, cum ar fi verificarea \u00eemprumutului variabilelor (borrow checker). Rust este de asemenea mai r\u0103sp\u00e2ndit dec\u00e2t limbajul OCaml utilizat \u00een prezent \u00een XAPI, ceea ce va simplifica atragerea de noi dezvoltatori \u00een proiect. <\/p>\n

\u00cen prima etap\u0103 se preconizeaz\u0103 dezvoltarea unui \u00eenlocuitor pentru c\u00e2teva componente, pentru a optimiza procesele \u0219i a preg\u0103ti baza pentru \u00eenlocuirea altor p\u0103r\u021bi ale stivei software. \u00cen special, \u00een primul r\u00e2nd, setul de instrumente pentru Linux guest tools, care \u00een prezent folose\u0219te limbajul Go, va fi rescris \u00een Rust, \u00eempreun\u0103 cu un proces de fundal pentru colectarea metricilor, scris \u00een OCaml. <\/p>\n

Necesitatea refacerii Linux guest tools (xe-guest-utilities) este generat\u0103 de problemele de calitate a codului \u0219i de dezvoltarea \u00een afara proiectului Xen Project sub controlul Cloud Software Group, ceea ce complic\u0103 formarea pachetelor \u0219i influen\u021ba comunit\u0103\u021bii asupra dezvolt\u0103rii. Noua variant\u0103 a setului de instrumente (xen-guest-agent) se va crea complet de la zero, f\u0103c\u00e2ndu-l c\u00e2t mai simplu posibil \u0219i separ\u00e2nd logica agentului de biblioteci. Procesul de fundal pentru colectarea metricilor (rrdd) va fi ref\u0103cut deoarece este compact \u0219i bine definit, ceea ce simplific\u0103 efectuarea experimentelor cu utilizarea noului limbaj \u00een dezvoltare. <\/p>\n

Anul viitor, ar putea \u00eencepe lucr\u0103rile pentru dezvoltarea componentului xenopsd-ng \u00een Rust, care va permite optimizarea arhitecturii stivei de programe. Ideea principal\u0103 este de a concentra \u00eentr-o singur\u0103 component\u0103 procesarea cu API-ul de nivel sc\u0103zut \u0219i de a organiza furnizarea tuturor API-urilor de nivel \u00eenalt c\u0103tre celelalte componente ale stivei. <\/p>\n
