Martin Stransky, mbajt\u00ebsi i pakove t\u00eb Firefox n\u00eb Fedora dhe RHEL, i angazhuar n\u00eb portimin e Firefox p\u00ebr Wayland, publikoi nj\u00eb raport me nj\u00eb p\u00ebrmbledhje t\u00eb arritjeve t\u00eb fundit n\u00eb p\u00ebrdorimin e Firefox n\u00eb ambientet t\u00eb bazuara n\u00eb protokollin Wayland. <\/p>\n
N\u00eb l\u00ebshimet e ardhshme t\u00eb Firefox pritet t\u00eb zgjidhen \u00e7\u00ebshtjet e v\u00ebzhguara n\u00eb nd\u00ebrtimet p\u00ebr Wayland lidhur me kopjimin dhe trajtimin e dritareve q\u00eb dalin (popup). K\u00ebto funksionalitete nuk ishin realizuar menj\u00ebher\u00eb p\u00ebr shkak t\u00eb dallimeve n\u00eb qasjen e realizimit t\u00eb tyre n\u00eb X11 dhe Wayland. N\u00eb rastin e par\u00eb, v\u00ebshtir\u00ebsit\u00eb u shfaq\u00ebn p\u00ebr shkak t\u00eb pun\u00ebs s\u00eb kopjimit t\u00eb Wayland n\u00eb m\u00ebnyr\u00eb asinkrone, q\u00eb k\u00ebrkonte krijimin e nj\u00eb shtrese t\u00eb ve\u00e7ant\u00eb p\u00ebr t\u00eb abstaruar qasjen n\u00eb kopjen Wayland. Kjo shtres\u00eb do t\u00eb shtohet n\u00eb Firefox 93 dhe do t\u00eb p\u00ebrfshihet si parazgjedhje n\u00eb Firefox 94. <\/p>\n
Sa i p\u00ebrket dritareve q\u00eb dalin, v\u00ebshtir\u00ebsia kryesore ishte se Wayland k\u00ebrkon respektimin e nj\u00eb hierarkie t\u00eb rrept\u00eb t\u00eb dritareve q\u00eb dalin, pra, nj\u00eb dritare prind mund t\u00eb krijoj\u00eb nj\u00eb dritare f\u00ebmij\u00eb me nj\u00eb popup, por nj\u00eb popup tjet\u00ebr i iniciuar nga kjo dritare duhet t\u00eb lidhet me dritaren f\u00ebmij\u00eb fillestare, duke formuar nj\u00eb zinxhir. N\u00eb Firefox, \u00e7do dritare mund t\u00eb krijonte disa popup, pa formuar nj\u00eb hierarki. Problemi ishte se p\u00ebrdorimi i Wayland shpiste q\u00eb mbyllja e nj\u00eb prej popup k\u00ebrkonte ri-nd\u00ebrtimin e gjith\u00eb zinxhirit t\u00eb dritareve me popup t\u00eb tjera, nd\u00ebrsa ka shum\u00eb her\u00eb q\u00eb ka disa popup t\u00eb hapura, pasi menut\u00eb, sugjerimet e papritura, dialog\u00ebt e shtesave, k\u00ebrkesat e autorizimit etj., jan\u00eb realizuar si popup. Situat\u00ebn e nd\u00ebrlikonte edhe mosperfekt\u00ebsit\u00eb n\u00eb Wayland dhe GTK, t\u00eb cilat b\u00ebnin q\u00eb ndryshimi i vog\u00ebl t\u00eb sillte regresione t\u00eb ndryshme. Megjithat\u00eb, kodi p\u00ebr trajtimin e dritareve q\u00eb dalin p\u00ebr Wayland \u00ebsht\u00eb p\u00ebrmir\u00ebsuar dhe planifikohet t\u00eb p\u00ebrfshihet n\u00eb Firefox 94. <\/p>\n
Nga p\u00ebrmir\u00ebsimet e tjera t\u00eb lidhura me Wayland, p\u00ebrmendet shtimi n\u00eb Firefox 93 i ndryshimeve q\u00eb lidhen me shkall\u00ebn n\u00eb ekranet me DPI t\u00eb ndrysh\u00ebm, t\u00eb cilat e eliminojn\u00eb dridhjen kur l\u00ebvizni dritaren n\u00eb skajin e ekranit n\u00eb konfigurimet me shum\u00eb monitor\u00eb. N\u00eb Firefox 95 planifikohet t\u00eb zgjidhen problemet q\u00eb ndodhin gjat\u00eb p\u00ebrdorimit t\u00eb nd\u00ebrfaqes drag&drop, p\u00ebr shembull, kur kopjoni skedar\u00eb nga burime ekstern n\u00eb sistemet lokale t\u00eb files dhe gjat\u00eb l\u00ebvizjes s\u00eb skedave. <\/p>\n
N\u00eb versionin Firefox 96, porti i Firefox p\u00ebr Wayland planifikon q\u00eb t\u00eb arrij\u00eb nj\u00eb barazim t\u00eb plot\u00eb n\u00eb funksionalitet me nd\u00ebrtimin p\u00ebr X11, t\u00eb pakt\u00ebn gjat\u00eb pun\u00ebs n\u00eb mjedisin GNOME t\u00eb Fedora. Pas k\u00ebsaj, v\u00ebmendja e zhvilluesve do t\u00eb kaloj\u00eb n\u00eb rafinimin e pun\u00ebs n\u00eb mjediset Wayland t\u00eb procesit GPU, n\u00eb t\u00eb cilin \u00ebsht\u00eb nxjerr\u00eb Kodi p\u00ebr nd\u00ebrveprimin me adaptator\u00ebt grafik\u00eb dhe q\u00eb mbron procesin kryesor t\u00eb shfletuesit nga d\u00ebshtimi n\u00eb rast ngacmimesh n\u00eb drejtuesit. N\u00eb procesin GPU gjithashtu planifikohet q\u00eb t\u00eb nxirret Kodi p\u00ebr dekodim video me ndihm\u00ebn e VAAPI, i cili aktualisht ekzekutohet n\u00eb proceset e p\u00ebrpunimit t\u00eb p\u00ebrmbajtjes. <\/p>\n
P\u00ebrve\u00e7 k\u00ebsaj, mund t\u00eb p\u00ebrmendet p\u00ebrfshirja p\u00ebr nj\u00eb p\u00ebrqindje t\u00eb vog\u00ebl t\u00eb p\u00ebrdoruesve t\u00eb deg\u00ebve stabile t\u00eb Firefox nj\u00eb mode t\u00eb rrept\u00eb t\u00eb izolohis\u00eb s\u00eb faqeve, q\u00eb \u00ebsht\u00eb zhvilluar n\u00eb kuad\u00ebr t\u00eb projektit Fission. Ndryshe nga shp\u00ebrndarja arbitrare e trajtimit t\u00eb skedave nd\u00ebrmjet proces\u00ebve t\u00eb disponuesh\u00ebm (n\u00eb parazgjedhje 8), moda e izolohis\u00eb trajton \u00e7do faqe n\u00eb procesin e saj t\u00eb ve\u00e7ant\u00eb, duke ndar\u00eb jo sipas skedave, por sipas domaineve (Public Suffix), e cila lejon izolimin e p\u00ebrmbajtjes nga skriptet e jashtme dhe blloqet iframe. Menaxhimi i aktivizimit t\u00eb mod\u00ebs Fission b\u00ebhet p\u00ebrmes variabl\u00ebs \"fission.autostart=true\" n\u00eb about:config ose n\u00eb faqen about:preferences#experimental. <\/p>\n
Moda e izolimit strikte lejon mbrojtjen nga sulmet p\u00ebrmes kanaleve t\u00eb jashtme, p\u00ebr shembull, t\u00eb lidhura me vulnerabilitetet e klas\u00ebs Spectre, si edhe zvog\u00eblon fragmentimin e memories, duke kthyer m\u00eb efikasisht memory-n\u00eb n\u00eb sistemin operativ, minimalizon ndikimin e mbledhjes s\u00eb plehrave dhe llogaritjeve intensive n\u00eb faqet n\u00eb procese t\u00eb tjera, rrit efektivitetin e shp\u00ebrndarjes s\u00eb ngarkes\u00ebs n\u00eb b\u00ebrthamat e ndryshme t\u00eb CPU-s\u00eb dhe rrit stabilitetin (d\u00ebshtimi i procesit q\u00eb p\u00ebrpunon iframe nuk do t\u00eb t\u00ebrheq\u00eb me vete faqen kryesore dhe tabat e tjera). <\/p>\n
N\u00eb mesin e problemeve t\u00eb njohura q\u00eb lindin gjat\u00eb p\u00ebrdorimit t\u00eb mod\u00ebs s\u00eb izolimit strikte, v\u00ebrehet rritja e dukshme e konsumit t\u00eb memories dhe deskriptor\u00ebve t\u00eb skedar\u00ebve kur hapen nj\u00eb num\u00ebr i madh tabash, si edhe nd\u00ebrprerje n\u00eb funksionimin e disa shtesave, humbje e p\u00ebrmbajtjes iframe gjat\u00eb printimit dhe thirrjes s\u00eb funksionit t\u00eb regjistrimit t\u00eb screenshot-it, ulje e efektivitetit t\u00eb caching t\u00eb dokumenteve me iframe, humbje e p\u00ebrmbajtjes s\u00eb formave t\u00eb mbushura, por jo t\u00eb d\u00ebrguara gjat\u00eb rikthimit t\u00eb seanc\u00ebs pas d\u00ebshtimit. <\/p>\n
