Crash when removing relation and related entity #490

And in BoxStore.java, it show me that: |
|
Is this reproducible? Which version is it? |
|
I got it recently. In my case problem was in attempt to deploy existing db image instead of empty after access to db.
|
|
OK, we should look into it to fail more nicely... |
|
@greenrobot Yes, it is reproducible. And objectbox version is v1.3.4.
|
|
@williamwue So you can rule out it is the same scenario compared to Yazon2006's?
Do you have a percentage of users? |

I've got a crash and it's logcat output looks very similar to the one reported above: ObjectBox version is 1.5.0. The crash appears only upon trying to update an app to a newer version, a fresh installation works ok, so it must have something to do with the way migrations are handled. Here's a list of the database-related changes I've made that led to a crash:
@Entity
data class DbPrice(
@Convert(dbType = String::class, converter = BigDecimalConverter::class)
var value: BigDecimal,
var currency: String,
@Id var id: Long = 0
)data class Price(
val value: BigDecimal,
val currency: String
)class PriceConverter : PropertyConverter<Price, String> {
override fun convertToDatabaseValue(entityProperty: Price?): String? = entityProperty?.let {
"${it.value}|${it.currency}"
}
override fun convertToEntityProperty(databaseValue: String?): Price? = databaseValue?.let {
val parsed = databaseValue.split("|")
Price(BigDecimal(parsed[0]), parsed[1])
}
}
@Entity
data class DbZone(
@Id(assignable = true)
var id: Long = 0,
val name: String? = "",
@Convert(converter = PriceConverter::class, dbType = String::class)
val fee: Price? = null,
@Convert(converter = ZoneStatusConverter::class, dbType = Int::class)
val status: Zone.Status = Zone.Status.DISABLED
)
@Entity
data class DbArea(
var name: String,
var parent: String,
@Id(assignable = true) var id: Long = 0,
var zoneId: Long?
)to this: @Entity
class DbArea {
@Id(assignable = true)
var id: Long = 0
lateinit var name: String
lateinit var parent: String
lateinit var zone: ToOne<DbZone>
}I didn't add any

Am also interested in this issue. Are there any updates? |
|
We would need a new crash log (starting with *** *** *** ...) with version 2.0.0-beta2. |
|
i change ToMany to String |
|
@ibnux Do you have the same crash? If so, please attach the crash log as requested above. Otherwise please submit a new issue, preferably with an example, so we can reproduce this. -ut |

@greenrobot I have a reliable reproduction for this case in the form of this repo: https://github.com/raja-baz/objectbox-490-reproduction Steps to reproduce:
This seems to be an issue during migration when an entity which is used as a target for a relation is removed. Some additional tests show that:
For now, we've decided to keep the legacy entities and not delete them to work around this issue while just not using them. Obviously this isn't ideal, but a segfault on app launch is even less ideal :P Cheers PS: This is on latest object box(2.1) and the crash in question is: |
|
Note that my crash seems very similar to the one @s0nerik reported but not the original one(null pointer dereference versus what looks like an exception being thrown). Would you rather I file this as a separate issue? |
|
@raja-baz Thanks for your repro project, could verify the crash. Using this issue is fine as the original reporter has not responded. Passed this on to the development team. |

@greenrobot , any updates on the bug fix? I encountered similar crash as well. |
|
Thanks again everyone for reporting. A fix was issued internally and will be available with the next update. |
|
This is also part of the just released version '2.4.0-RC' - would be great if you could give it a try and report back. Thank you! |

@greenrobot I was having this same issue and I don't see it anymore with |
When I upgrade app it would crash when init objectbox, logcat is below:
