deleteAllFromRealm() issue with gradle-plugin:10.13.0 - OK with realm-gradle-plugin:10.12.0

[LeonardDaVinci]

How frequently does the bug occur?

All the time

Description

Hello,

I wanted to upgrade realm in my Android (Dolphin) project from dependencies = classpath 'io.realm:realm-gradle-plugin:10.12.0' to dependencies = classpath 'io.realm:realm-gradle-plugin:10.13.0'

I have noticed that using exactly the same code, deleteAllFromRealm() does NOT work with gradle-plugin:10.13.0 - records are not deleted at all!

Making the same with with gradle-plugin:10.12.0 all records get deleted as usual.

This is the piece of code, that has two differents results using it with Realm 10.12.0 or Realm 10.13.0

public void deleteOrderHistoriesFromDB(final String time) {
    realm.executeTransactionAsync(new Realm.Transaction() {
        @Override
        public void execute(@NonNull Realm realm) {
            RealmResults<OderHistoryOl> results = realm.where(OderHistoryOl.class).equalTo("time", time).findAll();
            results.deleteAllFromRealm();
        }
    });
}

Am I making some mistake in code?

Thank you for help.

Hi @LeonardDaVinci

I tried to reproduce this behavior, but it seems to work also in 10.13. Your code looks correct, but it sounds like something you can reproduce?

Perhaps it is a problem with your input parameter to the function. Have you verified that RealmResults<OderHistoryOl> results actually returns any results?

[LeonardDaVinci]

Thank you. Yes, I checked again with debug and have seen that input parameters (time) is always present, having right values with 10.12 and also with 10.13 Really strange.. 10.12 delete but 10.13 not..

What I suppose: my app is a waiter order app for restaurant. In this case it does

1. Build and array on new products (order)
2. Save to Realm (asynchronously) as backup before calling an api to save to web server
3. Save to pc using api / apache web server
4. If api saving = Success then
5. I make results.deleteAllFromRealm() to delete backup order from Realm on device

And here is the problem: could it be that the asynchronous saving at step 2 is very very slow and it is not immediately saved on Realm but they get saved AFTER my step 5?

Is there a way to immediately force a flush when saving or deleting objects in Realm?

Hi @LeonardDaVinci. It seems the asynchronous call may be running too slowly. You could try to run those steps synchronously and see if the problem is solved. You can try with realm.executeTransaction instead, that would run it synchronously and you might avoid a possible race condition.

Hi @edualonso. I made test, writing also using .allowQueriesOnUiThread(true) but still no luck. I wrote .executeTransaction but app crash!... I have to think some other solution..

Hi @LeonardDaVinci we need more context about the issue to tell what's going on. Would you be able to create and share a test project that reproduces this issue?
