Google Chrome ayaa ugu dambayntii baabi'inaysa mareegaha si xun u isticmaala ogeysiisyada riixitaanka . Chrome waxa uu ku darayaa sifo cusub #Push-Subscription-With-Expiration-Time gadaashiisa chrome://flags kaas oo xaddidi doona riixista isdiiwaangelinta ilaa 90 maalmood, TheWindowsClub ayaa bartay. Calankan ayaa awood u siin doona Riix ^(Push) Diiwaangelinta^{(Subscriptions)} si ay u taageeraan wakhtiga dhicitaanka.

Chrome oo wax ka qabanaya ogeysiisyada xadgudubka

Waqtiga qorista maqaalkan, calankani lagama heli karo Chrome Canary ee la cusboonaysiiyay . Laakiin sida uu dhigayo Chromium Gerrit , si guul leh ayaa dib loogu dhisay oo loo gudbiyay Google Chrome Canary 86 oo la cusboonaysiiyay . Waxaa laga yaabaa in shaqadu ay wali socoto waxaanan filan karnaa in calankan tijaabada ah la hirgaliyo mustaqbalka Chrome Canary waxa uu dhisayaa maalmaha soo socda^{(future Chrome Canary builds in the coming days)} .

“This CL enables Push Subscriptions to support a expiration time, set by Chrome in push_messaging_constants.h (currently 90 days),” the description reads.

“This feature is disabled by default, so to try it out you must set –enable-features= PushSubscriptionWithExpirationTime.”

Sida laga soo xigtay horumariyeyaasha Chromium , tani waxay ku dari doontaa wakhtiga dhicitaanka (90 maalmood) marka la isu-diiwaangelinayo si loo riixo ogeysiisyada iyo habka is-diiwaangelinta laftiisa. Sifadan gaarka ah waxay dhaafi doontaa wakhtiga dhicitaanka sifo libiqsi.

"Sifada wakhtiga dhicitaanka waxaa lagu soo saari doonaa adeega riixitaanka. Marka dib loogu soo celiyo Isdiiwaangelinta Dib^{(SubscriptionCallback)} -u-soo-celinta (null waa ansax), waxay u baahan tahay in loo gudbiyo lakabka biliglaanshaha."

Chrome waxay u badan tahay inay hirgeliso isbeddellada UI gaar ah oo ku dhiirigelin doona isticmaaleyaasha inay dejiyaan ogeysiiskooda riixitaanka inay dhacayaan ka dib muddo cayiman. Waa la arki doonaa haddii isticmaalayaashu ay habayn karaan waqtiga xaddidan iyo in kale. Waxyaabaha ugu horreeya^(First) marka hore, waxay u egtahay in sifadani ay si cad u sheegi doonto ku biiritaanku dhicitaanka marka ogeysiisyada riixitaanka la qoro markii ugu horeysay.

Waxa jira dhawr dhinac oo ku lug leh hawsha oo dhan. Marka isticmaalayaashu ay iska diiwaan galiyaan ogeysiisyada, macluumaadka ku saabsan xidhitaanka dhicitaanka ayaa lagala soo bixin doonaa app_identifier oo dib loogu soo wici doonaa PushMessagingManager . Chrome wuxuu ku kaydin doonaa wakhtiga dhicitaanka PushMessagingAppIdentifier . Si kastaba ha ahaatee, tan weli lama hirgelin. Taasi waxay tidhi, qaabkani wuxuu si firfircoon uga hooseeya horumarka.

Marka calankaan la helo, waxaad awood u siin kartaa Google Chrome Canary .

Sida loo awood riixo^{(Push Subscription)} Isdiiwaangelinta Calanka Wakhtiga dhicitaanka ee ^{(Expiration Time)}Chrome

1. Fur Chrome Canary
2. Fur chrome://flags
3. ^{(Locate Push Subscription)}Hel Is - diiwaangelinta riix ee Wakhtiga dhicitaanka^{(Expiration Time)}
4. Calan^(Set) u deji si aad isla markiiba u suurtageliso^(Enable) marka tab la qariyo adiga oo isticmaalaya liiska hoos-u-u-dhaca
5. Dib u billow Chrome

Si loo soo koobo, sifadani waxay ku dari doontaa dhicitaanka isdiiwaangelinta wakhtiga aad is-diiwaangelinayso ogeysiisyada. Dhanka kale, Chrome waa inuu go'aansadaa meesha lagu keydiyo wakhtiga dhicitaanka ee dhinaca wakiilka isticmaalaha. Hagaag, sifadan ayaa noqon doonta mid ikhtiyaari ah waxayna ku xidhan tahay isticmaalayaasha inay go'aan ka gaadhaan inay rabaan iyo in kale inay rabaan rukhsadnimadooda inay dhacayso 90 maalmood ka dib.

Horumarinta Chromium ayaa si firfircoon uga shaqaynayey sifadan tan iyo bishii hore. TheWindowsClub waxay aragtay dhowr Chromium Gerrit oo ay samaysay kuwaas oo xaqiijinaya horumarka.

Waxaan cusbooneysiin doonaa maqaalkan isla marka astaantan tijaabada ah calanka #Push-Subscription-With-Expiration-Time uu ku hoos jiro chrome://flags .

Google Chrome to limit push notification subscriptions to 90 days

Google Chrome is finally cracking down on websites abusіng push notifications. Chrome is adding a new featυre #Push-Subscription-With-Expiration-Time behind chrome://flags that will limit push notification subscriptions to 90 days, TheWindowsClub has learned. This flag will enable Push Subscriptions to support an expiration time.

Chrome addressing notifications abuse

At the time of writing this article, this flag is not available in the updated Chrome Canary. But as per Chromium Gerrit commit, it has been successfully rebased and submitted to the updated Google Chrome Canary 86. Perhaps the work is still in progress and we can expect this experimental feature flag to be implemented to future Chrome Canary builds in the coming days.

“This CL enables Push Subscriptions to support a expiration time, set by Chrome in push_messaging_constants.h (currently 90 days),” the description reads.

“This feature is disabled by default, so to try it out you must set –enable-features= PushSubscriptionWithExpirationTime.”

According to Chromium developers, this will add expiration time (90 days) when subscribing to push notifications and in the subscribe method itself. This particular feature will Pass expiration time attribute to blink.

“The expirationTime attribute will be generated through the push service. When getting it back in the SubscriptionCallback (null is valid), it needs to be passed down to the blink layer.”

Chrome is likely to implement certain UI changes that will prompt users to set their push notification subscription to expire after a specific period. It remains to be seen whether or not users can customize the time frame. First things first, it looks like this feature will clearly communicate subscription expiry when push notifications are subscribed for the first time.

There are several parties involved in the entire process. Once users subscribe to notifications, information about subscription expiry will be retrieved from the app_identifier and sent back as a callback to PushMessagingManager. Chrome will store expiration time in PushMessagingAppIdentifier. However, this has not been implemented yet. That said, this feature is actively under development.

Once this flag is available, you can enable it on Google Chrome Canary.

How to enable the Push Subscription With Expiration Time flag in Chrome

1. Open Chrome Canary
2. Open chrome://flags
3. Locate Push Subscription With Expiration Time
4. Set the flag to Enable immediately when a tab is hidden using the drop-down menu
5. Relaunch Chrome.

To summarize, this feature will add expiry to subscriptions at the time of subscribing to notifications. Meanwhile, Chrome has to decide where to save expiration time on the user agent side. Well, this feature will be optional and it will be up to users to decide whether or not they want their push subscriptions to expire after 90 days.

Chromium developers have been actively working on this feature since last month. TheWindowsClub has spotted several Chromium Gerrit commits that confirm the development.

We will update this article as soon as this experimental feature flag #Push-Subscription-With-Expiration-Time is available under chrome://flags.
