Memory leak with Apollo Client in react native on iOS

[otusweb]

Intended outcome:
Run the application without a quickly increasing memory footprint causing the OS to kill the app

Actual outcome:

The memory footprint of the app quickly grows until the system decides to kill the application. Looking at the profiling information from Instruments, it looks like little chunk of 112 bytes are being allocated quickly and causing the memory usage to spin out of control

How to reproduce the issue:

Code

Note i'm new to this codebase and while a little familiar with Apollo, i'm by no mean an advanced user :-) So feel free to let me know if you need more info.

In a react native app.

const logErrorLink = onError(({ graphQLErrors, networkError, operation }) => {
  reportError(
    new Error(`Error Apollo ${operation.operationName}`),
    (report) => {
      const _params = {
        data: {
          operationName: operation.operationName,
          extensions: operation.extensions,
          query: operation.query,
          variables: operation.variables,
          conext: operation.getContext(),
          graphQLErrors,
          networkError,
        } as any,
      };
      report.addMetadata('report', _params);
    }
  );

});

const withToken = setContext(async () => {
  const user = auth().currentUser;
  let token = '';
  try {
    if (user) {
      token = await user.getIdToken();
    }
  } catch (error) {
    consoleDebug('error la', error);
  }
  return { token, uid: user?.uid || '' };
});

const authMiddleware = new ApolloLink((operation, forward) => {
  const { token, uid } = operation.getContext();
  operation.setContext(() => ({
    headers: {
      ...createRequestParams(uid, 'apollo', operation.operationName),
      Authorization: token ? `Bearer ${token as string}` : '',
    },
  }));
  return forward(operation);
});

const retryLink = new RetryLink({
  delay: (retryNumber) => {
    const delay = Math.pow(2, retryNumber) * 300;
    const randomSum = delay * 0.2 * Math.random(); // 0-20% of the delay
    return delay + randomSum;
  },
  attempts: {
    max: 4,
    retryIf: async (error, operation) => {
      if (error.statusCode === 401) {
        const user = auth().currentUser;
        const { uid } = operation.getContext();
        let token = '';
        if (user) {
          token = await user.getIdToken(true);
          bugsnag.leaveBreadcrumb('new refreshToken apollo');
        }
        if (token) {
          operation.setContext({
            headers: {
              ...createRequestParams(uid, 'apollo', operation.operationName),
              Authorization: `Bearer ${token}`,
            },
          });
          return true;
        }
      }
      return true;
    },
  },
});
const link = ApolloLink.from([
  retryLink,
  logErrorLink,
  withToken,
  authMiddleware.concat(persistedQueriesLink.concat(httpLink)),
]);
const linkPayment = ApolloLink.from([
  retryLink,
  logErrorLink,
  withToken,
  authMiddleware.concat(persistedQueriesLink.concat(httpLinkPayment)),
]);

const client = new ApolloClient({
  cache: new InMemoryCache(),
  name: `mobile-${Platform.OS}`,
  version: DeviceInfo.getReadableVersion(),
  // link: concat(authMiddleware, httpLink)
  link,
});

async processUser(data: any) {
    try {
      await client.mutate({
        mutation: updateUserMutation,
        variables: {
          data,
        },
      });
    } catch (e) {
      console.log('NEw apollo user', e);
    }
  }

Update user mutation

mutation updateUser($data: Json!) {
  updateUser(data: $data)
}

Run the app from Xcode by selecting Product > Profile

Once the method processUser is called, the memory footprint start to grow and the app crashes within 30s to 1 minute.

The image below shows the allocation of those 112 bytes of memory chunk over 25 seconds until the app is killed

Looking at where this memory is allocated shows the following stack trace (some are from different places, but 99% is from this place):

I'm unsure if this is related to #8903 or not

The example above is on a mutation, but it also happens on query

const linkPayment = ApolloLink.from([
  retryLink,
  logErrorLink,
  withToken,
  authMiddleware.concat(persistedQueriesLink.concat(httpLinkPayment)),
]);


const clientPayment = new ApolloClient({
  cache: new InMemoryCache(),
  name: `mobile-${Platform.OS}`,
  version: DeviceInfo.getReadableVersion(),
  // link: concat(authMiddleware, httpLink)
  link: linkPayment,
});


  async getUserBalance(): Promise<number> {
    try {
      const datadd = await clientPayment.query({
        query: userBalanceQuery,
      });
      return datadd.data.getUserBalance || 0;
    } catch (e) {
      return 0;
    }
  }

Once getUserBalance is called I get the same results.

@otusweb Just so everything's up-to-date, can you try updating to @apollo/[email protected]? Release notes here if you need them (especially the note about .cjs and React Native).

I have no real basis for this conjecture, but I have a hunch it may be time to retire the React Native exception for canUseWeakMap, which was necessary in the past because React Native's WeakMap implementation was unreliable/slow. If you want to try making that change locally (ignore navigator.product) and retest your memory consumption, that would save me cutting a one-off release for testing (which I'm also happy to do if that's easiest).

[otusweb]

@benjamn I updated and tried changing
export var canUseWeakMap = typeof WeakMap === 'function' && !(typeof navigator === 'object' && navigator.product === 'ReactNative');
to
export var canUseWeakMap = typeof WeakMap === 'function' && !(typeof navigator === 'object');

Unfortunately, this did not solve our issue.

[otusweb]

An extra piece of information is that it is only reproducible in release builds. The memory footprint is stable while using debug release.

[otusweb]

Turns out this is not due to Apollo, but something we were doing in one of our middleware.
