While putting together some benchmarks in a fork of Realm’s benchmarks, I ran into a crash in Couchbase on Android. It happens every time I run the benchmarks with ./gradlew clean benchmarkReport on the couchbase branch.
After running for several minutes, it crashes consistently in one of two places, either from Database.getDocument() or Database.save() .
Here are the functions in the CouchbaseBenchmarks code that cause the crash:
private fun addObjects() {
val list: MutableList<MutableDocument> = mutableListOf()
for (i in 0 until size) {
list.add(MutableDocument(i.toString(), mapOf(
NAME to dataGenerator.getEmployeeName(i),
AGE to dataGenerator.getEmployeeAge(i),
HIRED to dataGenerator.getHiredBool(i)
)))
}
db.inBatch {
list.forEach { db.save(it) }
}
}
private fun deleteObjects() {
val query = QueryBuilder.select(SelectResult.expression(Meta.id))
.from(DataSource.database(db))
val results = query.execute()
for (result in results) {
val id = result.getString(0)
db.getDocument(id)?.let {
db.delete(it)
}
}
}
These are the two crash logs:
