Azienda Microsoft ha annunciato<\/a><\/noindex> sulla formazione di nuove build sperimentali di Windows Insider (build 18917), che includono il previamente annunciato strato WSL2 (Windows Subsystem for Linux), che consente l'esecuzione di file eseguibili Linux in Windows. La seconda edizione di WSL include un kernel Linux completo, invece di un emulatore che traduce al volo le chiamate di sistema Linux in chiamate di sistema Windows. <\/p>\n

L'uso del nucleo standard consente di ottenere la piena compatibilit\u00e0 con Linux a livello di chiamate di sistema e garantisce la possibilit\u00e0 di avviare senza soluzione di continuit\u00e0 i container Docker in Windows, oltre a implementare il supporto per i file system basati sul meccanismo FUSE. Rispetto a WSL1, in WSL2 \u00e8 notevolmente aumentata la prestazione delle operazioni di input\/output e del filesystem. Ad esempio, durante l'estrazione di archivi compressi, WSL2 \u00e8 20 volte pi\u00f9 veloce di WSL1, mentre per operazioni come 'git clone', 'npm install', 'apt update' e 'apt upgrade' \u00e8 2-5 volte pi\u00f9 veloce.<\/p>\n

In WSL2 \u00e8 incluso un componente basato sul kernel Linux 4.19, che viene eseguito nell'ambiente Windows tramite una macchina virtuale, gi\u00e0 utilizzata in Azure. Gli aggiornamenti per il kernel Linux vengono forniti tramite il meccanismo Windows Update e testati nell'infrastruttura di integrazione continua di Microsoft. Tutte le modifiche preparate per l'integrazione del kernel con WSL promettono di essere pubblicate sotto la licenza open source GPLv2. I patch preparati includono ottimizzazioni per ridurre il tempo di avvio del kernel, diminuire il consumo di memoria e mantenere nel kernel il minimo necessario insieme di driver e sottosistemi. <\/p>\n

Il supporto per la vecchia versione WSL1 \u00e8 mantenuto e entrambi i sistemi possono essere utilizzati fianco a fianco, a seconda delle preferenze degli utenti. WSL2 pu\u00f2 fungere da sostituzione trasparente di WSL1. Come in WSL1, i componenti dello spazio utente sono installati<\/a><\/noindex> separatamente e si basano su build di diversi distribuzioni. Ad esempio, per l'installazione in WSL nel catalogo Microsoft Store vengono suggeriti<\/a><\/noindex> build Ubuntu<\/a><\/noindex>, Debian GNU\/Linux, Kali Linux<\/a><\/noindex>, Fedora<\/a><\/noindex>,
\nAlpine<\/a><\/noindex>, SUSE<\/a><\/noindex> e openSUSE<\/a><\/noindex>. <\/p>\n

Ambiente vengono eseguiti<\/a><\/noindex> in un'immagine disco separata (VHD) con filesystem ext4 e una scheda di rete virtuale. Per interagire con il nucleo Linux proposto in WSL2 \u00e8 necessario abilitare una piccola script di inizializzazione nel pacchetto, che modifica il processo di avvio. Per passare tra le modalit\u00e0 di funzionamento delle distribuzioni \u00e8 stata proposta un nuovo comando 'wsl --set-version', e per scegliere la versione di WSL predefinita il comando 'wsl --set-default-version'.<\/p>\n
