Martin Stransky, mbajt\u00ebsi i paketave t\u00eb Firefox n\u00eb Fedora dhe RHEL, i angazhuar n\u00eb portimin e Firefox p\u00ebr Wayland, publikoi nj\u00eb raport mbi arritjet e fundit n\u00eb pun\u00ebn e Firefox n\u00eb mjediset e bazuara n\u00eb protokollin Wayland. <\/p>\n
N\u00eb l\u00ebshimet e ardhshme t\u00eb Firefox pritet t\u00eb zgjidhen problemet e v\u00ebrejtura n\u00eb nd\u00ebrtimet p\u00ebr Wayland, si\u00e7 jan\u00eb ato me bllokimin e shk\u00ebmbimeve dhe trajtimin e dritar\u00ebve t\u00eb daljes (popup). K\u00ebto funksionalitete nuk u arrit\u00ebn t\u00eb implementoheshin menj\u00ebher\u00eb p\u00ebr shkak t\u00eb ndryshimeve n\u00eb qasjen p\u00ebr implementimin e tyre n\u00eb X11 dhe Wayland. N\u00eb rastin e par\u00eb, v\u00ebshtir\u00ebsit\u00eb lind\u00ebn nga funksionimi i bllokimit t\u00eb shk\u00ebmbimit Wayland n\u00eb m\u00ebnyr\u00eb asinkrone, gj\u00eb q\u00eb k\u00ebrkoi krijimin e nj\u00eb shtrese t\u00eb ve\u00e7ant\u00eb p\u00ebr t\u00eb abstaraktuar qasjen n\u00eb bllokimin e shk\u00ebmbimit Wayland. Kjo shtres\u00eb do t\u00eb shtohet n\u00eb Firefox 93 dhe do t\u00eb aktivizohet si default n\u00eb Firefox 94. <\/p>\n
Sa i p\u00ebrket dialog\u00ebve t\u00eb daljes, v\u00ebshtir\u00ebsia kryesore ishte se Wayland k\u00ebrkon respektimin e nj\u00eb hierarkie t\u00eb rrept\u00eb t\u00eb dritareve t\u00eb daljes, q\u00eb do t\u00eb thot\u00eb se nj\u00eb dritare prind mund t\u00eb krijoj\u00eb nj\u00eb dritare f\u00ebmij\u00eb me nj\u00eb popup, por popup-i i ardhsh\u00ebm, i iniciuar nga kjo dritare, duhet t\u00eb lidhet me dritaren f\u00ebmij\u00eb origjinale, duke formuar nj\u00eb zinxhir. N\u00eb Firefox, \u00e7do dritare mund t\u00eb krijoj\u00eb disa popup-e, pa formuar nj\u00eb hierarki. Problemi \u00ebsht\u00eb se, duke p\u00ebrdorur Wayland, mbyllja e nj\u00eb prej popup-eve k\u00ebrkon rind\u00ebrtimin e gjith\u00eb zinxhirit t\u00eb dritareve me popup-e t\u00eb tjera, duke pasur parasysh se prania e disa popup-eve t\u00eb hapura nuk \u00ebsht\u00eb nj\u00eb p\u00ebrjashtim, pasi menus, sugjerime, dialog\u00eb shtesash dhe k\u00ebrkesa p\u00ebr leje implementohen si popup-e. Situata u komplikuar gjithashtu nga pap\u00ebrfundimet n\u00eb Wayland dhe GTK, t\u00eb cilat b\u00ebn\u00eb q\u00eb ndonj\u00eb modifikim i vog\u00ebl t\u00eb mund t\u00eb shkaktonte regresione t\u00eb ndryshme. Megjithat\u00eb, kodi p\u00ebr trajtimin e dritareve t\u00eb daljes p\u00ebr Wayland \u00ebsht\u00eb rregulluar dhe pritet t\u00eb p\u00ebrfshihet n\u00eb Firefox 94. <\/p>\n
Nga p\u00ebrmir\u00ebsimet e tjera q\u00eb i p\u00ebrkasin Wayland, p\u00ebrmendet shtimi n\u00eb Firefox 93 i ndryshimeve lidhur me skalimin n\u00eb ekranet me DPI t\u00eb ndrysh\u00ebm, t\u00eb cilat lejuan eliminimin e dridhjeve kur l\u00ebvizni dritaren n\u00eb skajin e ekranit n\u00eb konfigurimet me shum\u00eb monitor\u00eb. N\u00eb Firefox 95 planifikohet q\u00eb t\u00eb merret me problemet q\u00eb shfaqen gjat\u00eb p\u00ebrdorimit t\u00eb nd\u00ebrfaqes drag&drop, p\u00ebr shembull, kur kopjoni skedar\u00eb nga burime t\u00eb jashtme n\u00eb sistemet lokale dhe gjat\u00eb l\u00ebvizjes s\u00eb skedave. <\/p>\n
N\u00eb l\u00ebshimin e Firefox 96, porti i Firefox p\u00ebr Wayland pritet t\u00eb arrij\u00eb nj\u00eb barazi t\u00eb plot\u00eb n\u00eb funksionalitet me nd\u00ebrtimin p\u00ebr X11, t\u00eb pakt\u00ebn kur punoni n\u00eb mjedisin GNOME t\u00eb Fedora. Pasi t\u00eb p\u00ebrfundoj\u00eb kjo, v\u00ebmendja e zhvilluesve do t\u00eb p\u00ebrqendrohet n\u00eb p\u00ebrmir\u00ebsimin e funksionimit n\u00eb ambientet Wayland t\u00eb procesit GPU, n\u00eb t\u00eb cilin \u00ebsht\u00eb transferuar kodi p\u00ebr nd\u00ebrveprimin me adaptuesit grafik\u00eb dhe q\u00eb mbron procesin kryesor t\u00eb shfletuesit nga d\u00ebshtimet n\u00eb rast t\u00eb problemeve me drejtuesit. Po ashtu, n\u00eb procesin GPU pritet t\u00eb transferohet kodi p\u00ebr dekodimin e videove p\u00ebrmes VAAPI, i cili aktualisht ekzekutohet n\u00eb proceset e p\u00ebrpunimit t\u00eb p\u00ebrmbajtjes. <\/p>\n
P\u00ebr m\u00eb tep\u00ebr, mund t\u00eb p\u00ebrmendim p\u00ebrfshirjen p\u00ebr nj\u00eb p\u00ebrqindje t\u00eb vog\u00ebl p\u00ebrdoruesish t\u00eb deg\u00ebve stabile t\u00eb Firefox-it t\u00eb m\u00ebnyr\u00ebs s\u00eb fort\u00eb t\u00eb izolimit t\u00eb faqeve, e zhvilluar n\u00eb kuad\u00ebr t\u00eb projektit Fission. Ndryshe nga shp\u00ebrndarja arbitrare e p\u00ebrpunimit t\u00eb skedave sipas baselit t\u00eb procesit (normalisht 8), m\u00ebnyra e izolimit nxjerr p\u00ebrpunimin e \u00e7do faqeje n\u00eb procesin e saj t\u00eb ve\u00e7ant\u00eb duke e ndar\u00eb jo sipas skedave, por sipas domen\u00ebve (Public Suffix), q\u00eb lejon nj\u00eb izolim t\u00eb m\u00ebtejsh\u00ebm t\u00eb p\u00ebrmbajtjes s\u00eb skripteve t\u00eb jashtme dhe blloqeve iframe. Aktivizimi i m\u00ebnyr\u00ebs Fission kontrollohet p\u00ebrmes variabl\u00ebs \"fission.autostart=true\" n\u00eb about:config ose n\u00eb faqen about:preferences#experimental. <\/p>\n
Moda e strikt t\u00eb izolimit lejon mbrojtjen nga sulmet p\u00ebrmes kanaleve t\u00eb tjera, p\u00ebr shembull, ato t\u00eb lidhura me dob\u00ebsi t\u00eb klas\u00ebs Spectre, dhe gjithashtu redukton fragmentimin e memories, p\u00ebrmir\u00ebson kthimin m\u00eb efikas t\u00eb memories p\u00ebr sistemin operativ, minimizon ndikimin e grumbullimit t\u00eb mbetjeve dhe llogaritjeve intensive n\u00eb faqet n\u00eb procese t\u00eb tjera, rrit efikasitetin e shp\u00ebrndarjes s\u00eb ngarkes\u00ebs n\u00eb b\u00ebrthama t\u00eb ndryshme t\u00eb CPU dhe rrit stabilitetin (d\u00ebshtimi i procesit q\u00eb p\u00ebrpunon iframe nuk do t\u00eb shkaktoj\u00eb d\u00ebshtimin e faqes kryesore dhe skedave t\u00eb tjera). <\/p>\n
Mes problemeve t\u00eb njohura q\u00eb lindin kur p\u00ebrdoret moda e strikt t\u00eb izolimit, v\u00ebrehet rritje e dukshme e konsumit t\u00eb memories dhe descriptor\u00ebve t\u00eb skedar\u00ebve kur hapen numra t\u00eb m\u00ebdha skedash, si dhe shqet\u00ebsime n\u00eb funksionimin e disa shtesave, humbja e p\u00ebrmbajtjes s\u00eb iframe gjat\u00eb printimit dhe aktivizimit t\u00eb funksionit t\u00eb regjistrimit t\u00eb ekranit, ulja e efikasitetit t\u00eb memorizimit t\u00eb dokumenteve me iframe, humbja e p\u00ebrmbajtjes s\u00eb formave t\u00eb mbushura, por jo t\u00eb d\u00ebrguara, gjat\u00eb rikthimit t\u00eb sesionit pas nj\u00eb d\u00ebshtimi. <\/p>\n
