Long value on document changed after saved to db

itai.shalom2 · September 26, 2017, 1:40pm

Hi, I’m using couchbase lite 2.0 for Android. Take a look at this, after these 3 lines:

Log.d(TAG, "insert: before " + newTask.getLong(myId));
mDatabase.save(newTask);
Log.d(TAG, “insert: after” + newTask.getLong(myId));

Outputs for example:

insert: before 11989091
insert: after -4788125

insert: before 231548688
insert: after 0

But there are many other long that works. Can you help with this?

That’s almost certainly an encoder bug that was fixed on August 23rd. I don’t know which version of CBL Android incorporates the fix, but I would think it’s fixed in the latest build. (@hideki?) What build are you using?

Hi @itai.shalom2,

What DB version of CBL 2.0.0 are you using? Latest build (DB017) is built with the latest litecore module which has this fix.

I added another unit test with the value you are using. Latest code can handle these large long values.

@Test
public void testLargeLongValue2() throws CouchbaseLiteException {
    MutableDocument doc = createDocument("test");
    long num1 = 11989091L;
    long num2 = 231548688L;
    doc.setValue("num1", num1);
    doc.setValue("num2", num2);
    doc = save(doc).toMutable();
    Log.i(TAG, "num1 long -> " + doc.getLong("num1"));
    Log.i(TAG, "num2 long -> " + doc.getLong("num2"));
    assertEquals(num1, doc.getLong("num1"));
    assertEquals(num2, doc.getLong("num2"));
}

Thanks

The fix is already in DB16; I just verified this.
