[No QA] Run pod install if node_modules changed

[roryabraham]

Details

So what's going on here? Basically, only a relatively small portion of our iOS native code actually lives in ios/Pods. A lot of it actually lives in node_modules, and thanks to some pretty complex ruby scripts in our Podfile (from React Native / expo, not us), that native code gets bundled with the iOS build.

Furthermore, Expo modifies some of the native code's source in a post-integrate hook:

Patching imports for file: /Users/runner/work/App/App/node_modules/@react-native-firebase/crashlytics/ios/RNFBCrashlytics/RNFBCrashlyticsModule.m

This means that our current strategy for caching pod installs doesn't work as expected. Currently, we run a pod install if and only if:

• Podfile.lock changed or
• Podfile.lock and Manifest.lock have diverged

It does not account for if native code in node_modules has changed.

To fix it, we check if node_modules changed by looking for a diff in package-lock.json and patches. This is already handled by our SetupNode action, so we just return cache-hit from there.

Case study

@thienlnam was helpful in providing and example when a bad cache led to build failures here. If you look at the first run, you'll see that the node_modules cache was missed. So we would have run the pod install in that case ✅

Now, we run pod install if any of the following are true:

• Podfile.lock has changed
• Podfile.lock and Manifest.lock are out-of-sync
• package-lock.json or patches have changed

This should hopefully fix build errors stemming from a corrupted pod cache, without disabling caching altogether.

Fixed Issues

$ n/a - I don't think we have an issue; slack context in a few places but most recently here

Tests

Not really sure how to test, so we'll just have to be observant and hopefully we'll see more reliable iOS builds.

• Verify that no errors appear in the JS console

Offline tests

None.

QA Steps

None.

• Verify that no errors appear in the JS console

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 approved by marketing by adding the Waiting for Copy label for a copy review on the original GH to get the correct copy.
  • 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 form input styles:
  • I verified that all the inputs inside a form are aligned with each other.
  • I added Design label 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.

Not sure why I was getting a diff in compiled GH actions, but I think that someone just failed to do that during a dependency upgrade or something
