Ukukhishwa kwe-Wayland-Protocols 1.49

Iphakheji ye-wayland-protocols 1.49 ikhishwe, equkethe isethi yamaphrothokholi nezandiso ezihambisana nephrothokholi eyinhloko ye-Wayland futhi inikeze amakhono adingekayo ukwakha amaseva ahlanganisiwe kanye nezindawo zomsebenzisi.

Enguqulweni entsha:

• Добавлен экспериментальный протокол xx-fractional-scale, предоставляющий возможность масштабирования системы логических координат, значения в которой задаются целыми числами, для повышения точности позиционирования и увеличения разрешения логических координат до отдельных пикселей. Подобная возможность решает проблему с ограниченным разрешением системы логических координат, недостаточным для позиционирования на уровне отдельных пикселей, необходимого для полноценной реализации дробного масштабирования.
• В протокол «linux-dmabuf» добавлена поддержка работы на системах с несколькими GPU. На подобных системах клиент может согласовать с композитными сервером какой из GPU следует использовать.
• В протокол color-management-v1 добавлена поддержка метаданных изображений в формате BT.2100 для применения в композитном сервере специфичных обработчиков, позволяющих корректно отображать HDR-контент, созданный для Windows.

Wonke amaphrothokholi alandelana adlula ezigabeni zokuthuthukiswa, zokuhlola kanye nokuzinzisa. Ngemva kokuqeda isigaba sokuthuthukiswa (isigaba "esingazinzile"), iphrothokholi ifakwa egatsheni "lesiteji" futhi ifakwe ngokusemthethweni kusethi ye-wayland-protocols, futhi ngemva kokuqedwa kokuhlolwa, ithuthelwa esigabeni esizinzile. Amaphrothokholi asuka esigabeni "sesiteji" angasetshenziswa kakade kumaseva ayinhlanganisela namakhasimende lapho kudingeka khona ukusebenza okuhlobene. Ngokungafani nesigaba "esingazinzile", "esiteji" akuvunyelwe ukwenza izinguquko ezephula ukuhambisana, kodwa uma izinkinga nokushiyeka kukhonjwa ngesikhathi sokuhlolwa, ukushintshwa ngenguqulo entsha ebalulekile yephrothokholi noma esinye isandiso se-Wayland akukhishwanga.

Ukuze kusheshiswe ukulethwa kwamaphrothokholi kubathuthukisi kanye nokukhuthaza ukuqaliswa kusenesikhathi kwezivumelwano kumaphrojekthi akhona, kuqala ngokukhululwa kwangaphambilini, isigaba "sokuhlola" sengezwe, esivumela izinguquko eziphula ukuhambisana nokwengezwa kwezivumelwano "eziluhlaza" ezingalethwa kancane kancane ezingeni elifanele. Nakuba iphrothokholi idinga ukwakha ithimba lokusekela futhi ithole inombolo ethile yokuvuma (ama-ACK) kubabuyekezi ukuze ingene esigabeni sesiteji, idinga kuphela ukungatholi ukuphikisa (ama-NACK) phakathi nenkathi yokubuyekeza yamaviki amabili ukuze ingene esigabeni sokuhlola.

I-wayland-protocols suite okwamanje ihlanganisa amaphrothokholi alandelayo azinzile, ahambisana emuva:

• "isibukeli" - sivumela iklayenti ukuthi lenze izenzo zokukala nokunqampuna emaphethelweni obuso ohlangothini lweseva.
• "isikhathi sesethulo" - inikeza ukuboniswa kwevidiyo.
• I-"xdg-shell" iyisixhumi esibonakalayo sokudala nokusebenzisana nezindawo ezingaphezulu njengamawindi, okukuvumela ukuthi uzihambise esikrinini, zigoqe, zinwebe, zishintshe usayizi, njll.
• "linux-dmabuf" - inikeza amandla okudala ama-wl_buffers asekelwe ku-DMA-BUF.

• i-fifo - isebenzisa indlela ye-FIFO (okokuqala, kuqala) yokucubungula umugqa wokubuyekeza okuqukethwe kwendawo ebonisiwe. Ngasohlangothini olusebenzayo, umthetho olandelwayo uvumela okukhiphayo ukuthi kusetshenziswe ukulinda ukuskena okuqondile ukuze kuqedwe (vblank) esikhundleni sokusebenzisa izingcingo zokuphinda ushaye isikhathi ngasinye lapho ilungele ukubonisa uhlaka olusha, oluxazulula inkinga yomthwalo we-GPU ephezulu uma usebenzisa i-VSync.
• ukwenza isikhathi - kukuvumela ukuthi ubophe umkhawulo wesikhathi kokuqukethwe okungaphezulu (iseva eyinhlanganisela kufanele ibonise ushintsho lokuqukethwe uma kungenzeka ngemuva kwesikhathi esishiwo, kodwa hhayi ngaphambili).
• i-ext-data-control - Ivumela amaklayenti akhethekile ukuthi alawule ukucutshungulwa kwedatha, isibonelo ukusebenzisa abaphathi bebhodi lokunamathisela.
• i-ext-workspace - isebenzisa umqondo wamadeskithophu abonakalayo futhi inikeza imicimbi enolwazi mayelana nesimo samadeskithophu, kanye nekhono lokuvula nokuvala amadeskithophu. Iphrothokholi ingasetshenziswa ukwenza amaphaneli nezinkomba ezibonisa uhlu lwamadeskithophu atholakalayo futhi akuvumela ukuthi ushintshe phakathi kwawo.
• ukuphathwa kombala — kunikeza amandla okuphatha imibala nokusekelwa kokukhanya okuguquguqukayo okunwetshiwe (i-HDR, Ibanga Elinamandla Eliphezulu). Ngesandiso esengeziwe, izinhlelo zokusebenza zeklayenti zingathola ulwazi mayelana nezakhiwo ezihlobene nemibala yamadivayisi okukhiphayo futhi zidlulisele idatha emayelana nezimpawu ezihambisana nemibala yokuqukethwe kwazo kuseva eyinhlanganisela. Kuseva eyinhlanganisela, lolu lwazi lungasetshenziselwa ukuphatha umbala ngokuzenzakalelayo lapho kukhombisa okuqukethwe kumadivayisi ahlukene okukhiphayo, isibonelo ukuguqula okuqukethwe kube isethulo esifanele ukuboniswa kumamonitha e-HDR. Amaphrofayili e-ICC asetshenziselwa ukuchaza izikhala zemibala.
• I-xdg-toplevel-tag — Ivumela amaklayenti e-Wayland ukuthi anamathisele omaka ezindaweni ezisezingeni eliphezulu iseva ehlanganisayo engazisebenzisa ukukhomba amawindi ngemva kokuthi uhlelo luqaliswe kabusha (isibonelo, uhlelo lokusebenza lungasetha "iwindi eliyinhloko" kanye "nezilungiselelo" zomaka ewindini elikhulu kanye newindi lezilungiselelo). Ukuhlonza okunjalo kuyasiza ekubuyiseleni indawo, usayizi, kanye nezakhiwo zamawindi ngemva kokuqala kabusha, kanye nokuchaza imithetho ekhethekile yezinhlobo ezingazodwana zamawindi.
• ukumela umbala — kuchaza ukumelwa kombala kwendawo ye-Wayland. Amaklayenti e-Wayland angadlulisa imethadatha edingekayo ukuze kuchazwe ukubonakala obala, imodeli yombala, amasampula amancane, nobubanzi bokulinganisa, futhi isetshenziswe lapho kuguqulwa isigcinalwazi esinedatha ehambisana nemodeli yombala ye-YCbCr ibe isethulo se-RGB.
• i-ext-background-effect - isebenza imithelela ezingxenyeni ezibonisa ngale sendawo ye-Wayland, njengokufiphala kwangemuva.
• i-pointer-warp - Ivumela uhlelo lokusebenza ukususa isikhombi ngokushesha endaweni ethile.
• xdg-session-management — возможности для восстановления состояния и позиции окон прерванного сеанса, например, после аварийного завершения композитного сервера или приложения.

Amaphrothokholi athuthukiswa egatsheni lokuhlola:

• i-xx-session-management - ibuyisela isimo samawindi ngezikhathi eziphazamisekile (isibonelo, ngemva kokuphahlazeka komphathi oyinhlanganisela).
• indlela yokufaka ye-xx — ivumela izinhlelo zokusebenza ukuthi zisebenzise izindlela zokufaka umbhalo zamaseva ahlanganisiwe futhi zikhiqize umbhalo ofakiwe, ongasetshenziswa, isibonelo, ukudala amakhibhodi abonakalayo kanye nezendlalelo ze-IME (Input Method Editor) zokucubungula kokufaka.
• I-xx-text-input — ivumela amaseva ahlanganisiwe ukuthi asebenzise izindlela zokufaka futhi athumele umbhalo kuzinhlelo zokusebenza. Le phrothokholi ilinganisa ukusebenzisana phakathi kwamaseva ahlanganisiwe nezinhlelo zokusebenza futhi ivumela ukulawula izici ezifana nokudlulisa umbhalo wokufaka, ukuphatha imicimbi yokugxila kokufaka, kanye nokubheka imininingwane yensimu yokufaka (ulimi, ukukhethwa kombhalo, uhlobo lokuqukethwe).
• xx-cutouts — для получения информации о вырезах на экране (например, области под фронтальную камеру на экране смартфона).
• xx-zones — для создания и добавления окон верхнего уровня в «зоны» — окружения со своим пространством координат. Протокол позволяет организовать логическую расстановку окон, в которой каждое окно размещается относительно другого окна.
• xx-keyboard-filter — для перехвата клиентом выбранных событий клавиатуры, изменения событий ввода или блокирования передачи определённых событий в Wayland-поверхность, на которой установлен фокус ввода.
