PR Author Checklist

  • I linked the correct issue in the ### Fixed Issues section above
  • I wrote clear testing steps that cover the changes made in this PR
    • I added steps for local testing in the Tests section
    • I added steps for the expected offline behavior in the Offline steps section
    • I added steps for Staging and/or Production testing in the QA steps section
    • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
    • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
    • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
  • I included screenshots or videos for tests on all platforms
  • I ran the tests on all platforms & verified they passed on:
    • Android: Native
    • Android: mWeb Chrome
    • iOS: Native
    • iOS: mWeb Safari
    • MacOS: Chrome / Safari
    • MacOS: Desktop
  • I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
  • I followed proper code patterns (see Reviewing the code)
    • I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
    • I verified that the left part of a conditional rendering a React component is a boolean and NOT a string, e.g. myBool && <MyComponent />.
    • I verified that comments were added to code that is not self explanatory
    • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
    • I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
      • If any non-english text was added/modified, I verified the translation was requested/reviewed in #expensify-open-source and it was approved by an internal Expensify engineer. Link to Slack message:
    • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
    • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
    • I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
    • I verified the JSDocs style guidelines (in STYLE.md) were followed
  • If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
  • I followed the guidelines as stated in the Review Guidelines
  • I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
  • I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
  • I verified any variables that can be defined as constants (ie. in CONST.js or at the top of the file that uses the constant) are defined as such
  • I verified that if a function's arguments changed that all usages have also been updated correctly
  • If any new file was added I verified that:
    • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
  • If a new CSS style is added I verified that:
    • A similar style doesn't already exist
    • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
  • If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
  • If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
  • If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
  • If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
  • If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
    • I verified that all the inputs inside a form are aligned with each other.
    • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
  • If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
  • If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

Looks pretty good. I think you're right that we don't have to call DeferredOnyxUpdates.enqueueAndProcess directly. Also I merged your last PR so be sure to merge main to clear the old changes on this one.

// const updates = wrapAirshipUpdatesDataInOnyxUpdatesFromServer({onyxData, lastUpdateID, previousUpdateID});
// return DeferredOnyxUpdates.enqueueAndProcess(updates);

return Promise.all(onyxUpdates.map((update) => applyOnyxData(update)));

On second thought, I think we do need to enqueueAndProcess these updates as we're applying them in a random order here.

The end goal we're looking for is that all of the push notification updates are sorted and then applied in-order. The DeferredOnyxUpdates queue should be able to do that with enqueueAndProcess. Does that make sense?

The sorting and processing is actually also achieved by calling applyOnyxData. This will trigger applyOnyxUpdatesReliably which will then trigger handleOnyxUpdateGap and DeferredOnyxUpdates.enqueue functions consecutively.

Once the deferred updates are being processed by validateAndApplyDeferredUpdates they will be sorted and applied.

So we're essentially trying to avoid unnecessary calls to handleOnyxUpdateGap to begin with. For example, let's say our clientLastUpdateID is 10 and we have push notifications for updates 11-15. Ideally, we would apply them in-order and thus, detect no gaps as we do that.

If we applyOnyxUpdatesReliably in a random order, the first update will probably be out of order so it will trigger an unnecessary call to handleOnyxUpdateGap and GetMissingOnyxMessages. The following updates should just get enqueued and then processed like you said, but that first API call was unnecessary.

So we must sort and apply these updates synchronously and we should be able to do that with enqueueAndProcess. Do you follow?

@arosiclair i've updated the PR to use DeferredOnyxUpdates.enqueueAndProcess() directly, which will make sure the updates are sorted and applied synchronously.

Could you test if this brings the expected output when clicking on push notifications? It's hard to test this on the simulator (as i cannot build the Expensify app with (Remote) push notifications, because i'm not in the Expensify Apple Developer organization)

I'm gonna try to mock the push notification with the onyx payload later today, but first i have to work on some other stuff.

You should be able to test on Android (emulator or device are both fine). I'll give it a test on iOS though.

Alright I did some testing on iOS and have a few findings:

  1. It's not clear what's going on with the deferred updates queue when just looking at logs. We should add a couple to enqueue and process:
Log.info('[DeferredOnyxUpdates] enqueuing updates', false, { lastUpdateIDs: Object.keys(updates)});

Log.info('[DeferredOnyxUpdates] processing updates', false, { lastUpdateIDs: Object.keys(deferredUpdates)});
  1. It looks like clearReportNotifications is clearing notifications and their payloads before we get to enqueue them. Commenting out that function fixed the issue for me. So we need to just need to get the notifications before navigating. Something like:
function navigateToReport({reportID, reportActionID}) {
    Airship.push.getActiveNotifications().then((notifications) => {
        // ...
        DeferredOnyxUpdates.enqueueAndProcess(onyxUpdates);
  
        Navigation.isNavigationReady().then(...)
    }
}
  1. Even with the above changes, there's still a noticeable delay for the new messages to appear after killing the app, receiving push notifications and tapping one to view the chat. With the force offline toggle enabled, the messages never appear (presumably because the updates were never merged). It's not clear in logs if that's because there's a gap that cannot be filled while offline or another reason.

@chrispader Can you please update the checklist?

@arosiclair i've applied the changes you suggested and tested it on Android. In my case, the updates from the notifications are already applied when received, therefore they also appear in the report screen when navigated there.

Calling Airship.push.getActiveNotifications() actually doesn't give me any notifications on Android, could you check if this returns any notifications on iOS? I cannot test this in the iOS simulator. This means, there also are no deferred updates getting enqueued and processed.

(The Airship docs state, that on Android getActiveNotifications() will only return notifications passed through Airship, but i think this should be the case?)

Also, we still have the PushNotification.onReceived callback which will apply all (reliably) applicable updates when received. This means that the updates that are clicked/selected should already be applied at that point.

Is our approach, to "re-apply" all open/active notifications, in case these couldn't be applied (yet) or are missing?

Since i cannot really test this on iOS, where it seems to be the bigger problem, i'm not sure if i can properly test and work on this PR...

Could you test the current state and lmk if i can help with anything further?

@chrispader Can you please update the checklist?

@allroundexperts i completed the checklist so this PR is not blocked by me, but we still have to ensure this works on Android and iOS

It should work on both. That's what we use for clearReportNotifications. I'll give it a try on Android.

Also, we still have the PushNotification.onReceived callback which will apply all (reliably) applicable updates when received. This means that the updates that are clicked/selected should already be applied at that point.

Is our approach, to "re-apply" all open/active notifications, in case these couldn't be applied (yet) or are missing?

The idea is that sometimes the onReceived callback does not run and apply the onyx data after the app is killed in the background, so we would try to apply the onyx data again when you select any notification. However, I am seeing on iOS that the onReceived callback does eventually run when we re-open the app so we may be double applying right now. I'm going to do some more testing to see how we should proceed.

Since i cannot really test this on iOS, where it seems to be the bigger problem, i'm not sure if i can properly test and work on this PR...

Yeah it might be best for me to take over this PR. I'll put some work on it today
