Empresa Microsoft anunciou<\/a><\/noindex> sobre a forma\u00e7\u00e3o de novos builds experimentais do Windows Insider (build 18917), que inclui a camada WSL2 (Windows Subsystem for Linux) anteriormente anunciada, permitindo a execu\u00e7\u00e3o de arquivos execut\u00e1veis do Linux no Windows. A segunda edi\u00e7\u00e3o do WSL oferece um n\u00facleo Linux completo, ao inv\u00e9s de um emulador que traduz as chamadas de sistema do Linux em chamadas de sistema do Windows. <\/p>\n

O uso do n\u00facleo padr\u00e3o permite alcan\u00e7ar compatibilidade total com o Linux a n\u00edvel de chamadas de sistema e garantir a capacidade de executar cont\u00eaineres Docker no Windows de forma cont\u00ednua, al\u00e9m de implementar suporte a sistemas de arquivos com base no mecanismo FUSE. Comparado ao WSL1, o WSL2 apresenta um aumento substancial no desempenho de entrada\/sa\u00edda e opera\u00e7\u00f5es com o sistema de arquivos. Por exemplo, ao descompactar um arquivo comprimido, o WSL2 \u00e9 20 vezes mais r\u00e1pido que o WSL1, e ao executar opera\u00e7\u00f5es como «git clone», «npm install», «apt update» e «apt upgrade», \u00e9 de 2 a 5 vezes mais r\u00e1pido.<\/p>\n

No WSL2, \u00e9 oferecido um componente baseado no n\u00facleo Linux 4.19, que \u00e9 executado em um ambiente Windows atrav\u00e9s de uma m\u00e1quina virtual j\u00e1 utilizada no Azure. Atualiza\u00e7\u00f5es para o n\u00facleo Linux s\u00e3o entregues atrav\u00e9s do mecanismo Windows Update e testadas na infraestrutura de integra\u00e7\u00e3o cont\u00ednua da Microsoft. Todas as altera\u00e7\u00f5es preparadas para a integra\u00e7\u00e3o do n\u00facleo com o WSL prometem ser publicadas sob a licen\u00e7a livre GPLv2. As corre\u00e7\u00f5es preparadas incluem otimiza\u00e7\u00f5es para reduzir o tempo de inicializa\u00e7\u00e3o do n\u00facleo, diminuir o consumo de mem\u00f3ria e deixar no n\u00facleo um conjunto m\u00ednimo necess\u00e1rio de drivers e subsistemas. <\/p>\n

O suporte \u00e0 antiga vers\u00e3o WSL1 foi mantido e ambos os sistemas podem ser usados lado a lado, dependendo das prefer\u00eancias dos usu\u00e1rios. O WSL2 pode atuar como um substituto transparente do WSL1. Assim como no WSL1, os componentes do espa\u00e7o do usu\u00e1rio separadamente e baseiam-se em vers\u00f5es de diferentes distribui\u00e7\u00f5es. Por exemplo, para instala\u00e7\u00e3o no WSL no diret\u00f3rio Microsoft Store,<\/a><\/noindex> Alpine s\u00e3o oferecidos<\/a><\/noindex> compila\u00e7\u00f5es Ubuntu<\/a><\/noindex>, Debian GNU\/Linux, Kali Linux<\/a><\/noindex>, Fedora<\/a><\/noindex>,
\nA Microsoft anunciou a expans\u00e3o da funcionalidade do subsistema WSL2.<\/a><\/noindex>, SUSE<\/a><\/noindex> e Arch Linux<\/a><\/noindex>. <\/p>\n

Ambiente s\u00e3o executados<\/a><\/noindex> em uma imagem de disco separada (VHD) com sistema de arquivos ext4 e um adaptador de rede virtual. Para interagir com o n\u00facleo Linux disponibilizado no WSL2, \u00e9 necess\u00e1rio habilitar um pequeno script de inicializa\u00e7\u00e3o que modifica o processo de boot. Para alternar os modos de opera\u00e7\u00e3o das distribui\u00e7\u00f5es, foi introduzido um novo comando «wsl —set-version», e para escolher a vers\u00e3o padr\u00e3o do WSL, o comando «wsl —set-default-version».<\/p>\n
