Realm-java: Blackberry Z10: Function not implemented in io_realm_internal_SharedGroup.cpp line 113

[diegomontoya]

We got a lone wolf crash. Did not encounter any repeating or similar crashes before.

Maybe related to https://github.com/realm/realm-java/issues/1380 and recent core/jni changes in master.

Blackberry Z10
Android Version: 4.3
Realm Version: 1.1.1-SNAPSHOT (end of July 8th)

Non-fatal Exception: io.realm.exceptions.RealmError: Unrecoverable error. Function not implemented in io_realm_internal_SharedGroup.cpp line 113

That one was fixed in 0.84.0, but this is new.

I was trying to figure out what is wrong with BB z10 but the adb stops working with it :(

My guess is the newly add call to mkfifo in our underlying engine caused the problem ...

@diegomontoya Does the log say which function is not implemented?

[diegomontoya]

@beeender Unfortunately the func name is not in the log.

Is there any chance of this being a _very_ high priority? I'd like to upgrade a project to 1.1.0 (or above, in this case) but it needs to support pure Blackberry phones like the Z10 or the RIM Passport as well... and the project lifecycle is out of my hands, and I don't really want to keep it on 1.0.0. (although I will if need be)

[beeender]

@Zhuinden I will take a look at this issue next Monday.

[Zhuinden]

@beeender thank you! :+1:

[diegomontoya]

@beeender Any update on this? Thanks.

[beeender]

@diegomontoya Sorry for the late response. I spent a day for debugging on the z10, but it is really difficult (for me) to figure out which native function it cannot find. (Last time the function name comes with the exception message. No native backlog/I didn't find a way to connect gdb/very slow apk installation).

What I can confirm is it works up to v1.0.1.

I am sorry but we need to put this issue to a relative low priority right now. I think it will still take some time to get this fixed.

[Zhuinden]

That kinda makes me wish you had released 1.0.2 with the optional transformer disabled and otherwise being 1.0.1, but oh well.

[beeender]

Note for me: After wasting a few more hours: https://github.com/realm/realm-core/pull/1834 triggered issue and mkfifo works with my testing project on z10.

@Zhuinden Yeah, it is doable. We will make a 1.0.2 release soon.

[Zhuinden]

So that means the core issue has actually been identified?

That's pretty cool! A v1.0.2 is awesome too; a stable branch for the 1.0.x versions just in case.

[beeender]

Some updates:

1. BB 10's mkfifo() has a bug. When the fifo file exists, from the document, errno EEXIST should be set. But instead, it set errno to ENOSYS. And that has been translated to exception message "Function not implemented". However, this is not the critical one. It can be worked around by using stat() to check the st_mode.
2. BB 10's flock() with LOCK_EX doesn't work at all. It doesn't block. BB 10 doc for flock() .

[pwiniars]

I can confirm this also on BB Z30 and Passport. Any chance of bugfix?

[beeender]

@pwiniars Yes, fix is being reviewed right now :)

[Zhuinden]

Is this handled by 1.1.1, or only 1.2.0?

EDIT: silly question, I should just read the changelog - it's fixed :)

[beeender]

1.1.1 :tada:

Happened again here: https://github.com/realm/realm-java/issues/3735
But this time it's Blackberry Passport.
