Details

This PR adds three new functions to the OnyxUpdateManager which let you manage the updates in the deferred updates queue. It particularly a clean interface to access and control deferred updates.

The DeferredOnyxUpdates module mainly includes the following functions:

  • enqueue() let's you add updates to the queue. By default, this will automatically trigger processing these items with validateAndApplyDeferredUpdates
  • process() waits for the current queryPromise (when there are missing onyx updates currently fetched from the server) and then triggers validateAndApplyDeferredUpdates
    • enqueueAndProcess() combines the upper two functions by first enqueuing and then immediately processing the updates.
  • clear manually clears the deferred updates queue. By default, this unpauses the SequentialQueue as well.

Fixed Issues

$ #40227
PROPOSAL:

Tests

  • Verify that no errors appear in the JS console

To ensure the functionality from #39683 is preserverd:

  1. Create a chat report with a peer
  2. Create a policy room between both of you
  3. after those rooms are created, and both of you opened them at least once, comment these calls to make sure we're not reloading the data from the backend instead:
    if (isFromDeepLink) {
    // eslint-disable-next-line rulesdir/no-api-side-effects-method
    API.makeRequestWithSideEffects(SIDE_EFFECT_REQUEST_COMMANDS.OPEN_REPORT, parameters, {optimisticData, successData, failureData}).finally(() => {
    Onyx.set(ONYXKEYS.IS_CHECKING_PUBLIC_ROOM, false);
    });
    } else {
    // eslint-disable-next-line rulesdir/no-multiple-api-calls
    API.write(
    WRITE_COMMANDS.OPEN_REPORT,
    parameters,
    {optimisticData, successData, failureData},
    {
    getConflictingRequests: (persistedRequests) =>
    // requests conflict only if:
    // 1. they are OpenReport commands
    // 2. they have the same reportID
    // 3. they are not creating a report - all calls to OpenReport that create a report will be unique and have a unique createdReportActionID
    persistedRequests.filter((request) => request.command === WRITE_COMMANDS.OPEN_REPORT && request.data?.reportID === reportID && !request.data?.createdReportActionID),
    },
    );
    }
  4. Now send messages in both chat rooms, alternating between them, and fast, in a way that you can notice if anything is missing (so both start sending some kind of ordered messages, like sequential numbers)
  5. Make sure that none of the messages were lost in those chats.

Offline tests

Not needed.

QA Steps

  • Verify that no errors appear in the JS console

Same as in Tests.

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 on first glance, but could we rename the deferredUpdatesProxy lib to just DeferredUpdates and then move these enqueue, process and clear functions there? That way we can have a pretty clean API (eg: DeferredUpdates.enqueue())

That was my first idea as well, but we also want to be able to trigger validateAndApplyDeferredUpdates which requires accesing the queryPromise.

I think it's more robust if the developer just interacts with the OnyxUpdateManager and doesn't have to think about deferred updates too much. Do you agree?

I can still rename deferredUpdatesProxy to DeferredUpdates, that fine.

@chrispader

Still, i can also extract the queryPromise out of the OnyxUpdateManager (also with a proxy) and move the new functions to DeferredUpdates.

@arosiclair nevermind, i just changed the structure as you suggested. We now have a DeferredUpdates module that exports both the deferredUpdates itself as well as the new functions

Appreciate the changes! Just looking for a bit better encapsulation on the DeferredUpdates lib

As you might guess I'm not a big fan of this proxy object pattern 😄. These feel more or less like global variables and are prone to error in the same way since their values can be changed anywhere, at anytime and in any way.

It feels like we're pretty much creating a lock with this object so it would be nice if we could abstract it like one. However, I'm not sure exactly how it would look.

Cleaning this up is NAB but if you know an easy way to write it I'm curious.

@arosiclair i adapted the implementation, but it's still WIP. I'll update you tmrw!

@chrispader

@arosiclair this is now done! I moved and adapted the the deferred updates queue to DeferredOnyxUpdates.ts (i think this name is more clear). There's no direct access to the underlying deferredUpdates object anymore.

This module includes your requested functions as well as DeferredOnxyUpdates.enqueueAndProcess(), which will process the queue after pushing new updates immediately. enqueue() will just push them.

Looking good. Can you add some test steps? Also will the unit tests we added before cover these changes?

Yes, the unit and action tests actually already catched some issues while implementing this and they cover (all of) the functionality that are affected by these changes

Yeah @chrispader's testing steps only seem do-able on web and desktop so I think we can just test those.

This is testing fine. Messages are not getting lost but I was not able to confirm there order. Sometimes, they appeared out of order. Not sure if that is expected.
