Os desenvolvedores do sistema operacional de c\u00f3digo aberto Haiku, que continua a desenvolver as ideias do BeOS, prepararam uma implementa\u00e7\u00e3o inicial de uma camada para garantir a compatibilidade com a biblioteca Xlib, permitindo executar aplicativos X11 no Haiku sem o uso de um servidor X. A camada \u00e9 realizada por meio da emula\u00e7\u00e3o das fun\u00e7\u00f5es Xlib, traduzindo as chamadas para a API gr\u00e1fica de alto n\u00edvel do Haiku. <\/p>\n

Na sua forma atual, a camada fornece a maior parte das interfaces de programa\u00e7\u00e3o normalmente utilizadas do Xlib, mas algumas chamadas ainda permanecem substitu\u00eddas por substitutos. A camada permite compilar e executar aplica\u00e7\u00f5es baseadas na biblioteca GTK, mas a qualidade do layout dos elementos nas janelas ainda requer aprimoramentos. O tratamento de entrada atrav\u00e9s do teclado e cliques do mouse ainda n\u00e3o foi totalmente desenvolvido (apenas foi adicionada a manipula\u00e7\u00e3o do evento de movimento do mouse). <\/p>\n

O suporte \u00e0 biblioteca Qt no Haiku foi anteriormente implementado por meio da cria\u00e7\u00e3o de uma porta nativa do Qt, operando sobre a API do Haiku. No entanto, para suportar o GTK, o uso da emula\u00e7\u00e3o do X11 \u00e9 considerado uma op\u00e7\u00e3o mais prefer\u00edvel, j\u00e1 que os internos do GTK n\u00e3o s\u00e3o t\u00e3o bem abstra\u00eddos, e a cria\u00e7\u00e3o de um backend GTK separado para o Haiku exigiria recursos significativos. Como alternativa, foi considerada a possibilidade de criar uma porta do X11-servidor<\/a> para o Haiku, mas essa abordagem foi considerada inadequada nas condi\u00e7\u00f5es em que a API do X11 pode ser implementada diretamente sobre a API do Haiku. O X11 foi escolhido como um protocolo que foi estabilizado h\u00e1 muito tempo e que n\u00e3o muda, enquanto o Wayland ainda est\u00e1 em fase de experimenta\u00e7\u00e3o, requerendo a cria\u00e7\u00e3o de uma implementa\u00e7\u00e3o pr\u00f3pria do servidor, e nem todas as extens\u00f5es necess\u00e1rias do protocolo foram aprovadas definitivamente.

\"Foi<\/center> <\/p>\n

Ao executar aplicativos mais simples atrav\u00e9s da camada como Tcl\/Tk e wxWidgets, tamb\u00e9m s\u00e3o observados problemas ainda n\u00e3o resolvidos, mas a apar\u00eancia j\u00e1 est\u00e1 mais pr\u00f3xima do normal:

Lembramos que o projeto Haiku foi criado em 2001 como uma resposta ao encerramento do desenvolvimento do sistema operacional BeOS e evoluiu sob o nome OpenBeOS, mas foi renomeado em 2004 devido a reivindica\u00e7\u00f5es relacionadas ao uso da marca comercial BeOS. O sistema \u00e9 baseado diretamente nas tecnologias BeOS 5 e visa a compatibilidade bin\u00e1ria com aplica\u00e7\u00f5es desse sistema operacional. Os c\u00f3digos fonte da maior parte do sistema operacional Haiku s\u00e3o distribu\u00eddos sob a licen\u00e7a MIT, exceto por algumas bibliotecas, codecs de m\u00eddia e componentes provenientes de outros projetos. <\/p>\n

O sistema \u00e9 orientado para computadores pessoais, utiliza um n\u00facleo pr\u00f3prio baseado em uma arquitetura h\u00edbrida, otimizado para alta responsividade \u00e0s a\u00e7\u00f5es do usu\u00e1rio e para a execu\u00e7\u00e3o eficiente de aplica\u00e7\u00f5es multithread. O sistema de arquivos utilizado \u00e9 o OpenBFS, que suporta atributos de arquivos avan\u00e7ados, journaling, ponteiros de 64 bits, e suporte ao armazenamento de metadados (para cada arquivo, \u00e9 poss\u00edvel salvar atributos na forma chave=valor, o que torna o sistema de arquivos similar a um banco de dados) e \u00edndices especiais para acelerar as consultas. Para organizar a estrutura de diret\u00f3rios, s\u00e3o utilizadas \u00e1rvores do tipo \"B+ tree\". Do c\u00f3digo do BeOS, o Haiku inclui o gerenciador de arquivos Tracker e a barra de tarefas Deskbar, cujos c\u00f3digos-fonte foram liberados ap\u00f3s a interrup\u00e7\u00e3o do desenvolvimento do BeOS.
