- [X] I have run
gradle cleanand confirmed this bug does not occur with JSC
Hermes version: 0.5.2-rc1
React Native version (if any): 0.63.2
Android version (if any): This stack is from Android 9. Seen on Android 9 and 4.4.4, likely will happen on others over time
Platform (most likely one of arm64-v8a, armeabi-v7a, x86, x86_64): armeabi-v7a
Steps To Reproduce
- Unknown. Issue only happens in release. We have no way to get more information or reproduce this.
The Expected Behavior
Hermes should never crash in a release deployment

Looking at the stack trace, it doesn't seem obviously related to proxy. Looks like a call coming from native, pretty deep recursion.

@tmikov Yeah I have no clue what could be triggering these native crashes. They only seem to happen in the release build on end user devices. This is really driving us crazy, we're trying to launch our first beta test to get retention numbers but we have 10-30% of sessions crashing out in native code deep inside Hermes and RN with no real way to debug them. =(

@tmikov Possibly related to execute only memory on API 29? https://github.com/facebook/react-native/issues/29517
I downgraded target version to API 28 to try to avoid this but these crashes are happening on API 28 so I'm not sure if that helped or if it could be the root cause.

Hmm I'm wondering if I deobfuscated this against the right library. I used armeabi-v7a when it might have been an arm64 device. Here's what I get running ndk-stack against the arm64-v8a symbols:
********** Crash dump: **********
#00 0x000000000003b154 /data/app/com.myapp-f1Qt4zzD5t3YptWQ07Jqpg==/lib/arm/libhermes.so

/home/circleci/project/API/jsi/jsi/jsi.cpp:413:11
Crash dump is completed
Thanks for the deobfuscated stacks! This is definitely a help in diagnosing this.
This issue is one crash of four which all share a common property: facebook::jsi::dynamicFromValue is being used in a deeply recursive way before Hermes is being called. This function is used in the React Native bridge to convert a javascript JSI value to a folly::dynamic value. The source code is here https://github.com/facebook/react-native/blob/master/ReactCommon/jsi/jsi/JSIDynamic.cpp#L20-L57.
Thus, I believe all are actually the same root cause. dynamicFromValue is recursive, and uses stack proportional to the maximum recursion of JS arrays or objects crossing the bridge. I believe this app is generating such objects, passing them over the bridge, then Hermes reaches the end of the native stack, and crashes. Hermes has only limited mechanisms today to detect native stack overflow, so this results in a native crash instead of a RangeError.
We have plans to detect this better, but I don't have a timeline for this.
That said, dynamicFromValue is used by Hermes and JSC. So I would expect JSC to be exhibiting as many failures as Hermes is, but they would likely be manifesting as a RangeError or other JS exception, not as a native crash. If you have JSC crashes alongside Hermes ones, you might be able to use that to figure out where the failure is originating.

@mhorowitz just a random thought: would if the JSI value contained proxies?
tmikov
on 9 Sep 2020
@tmikov our app relies heavily on mobx-state-tree so an issue with proxy seems likely to affect us.
AndrewMorsillo
on 9 Sep 2020
@tmikov it would be fine.

@AndrewMorsillo your app uses Proxy and it crashes, but unfortunately so far there is no direct evidence that it is Proxy that is causing the crash - there is nothing Proxy-related in the stack traces :-( Why "unfortunately"? Well, even though we obviously don't want Proxy to be crashing, given that something is crashing, we would at least know where to look.
Our best working theory so far is that this is a stack overflow caused by a deeply nested object, but then why wouldn't it happen with JSC? And why wouldn't it happen in DEV mode (or does it?)?

It's possible that this is happening with JSC, we switched to hermes because we were seeing lots of random crashes on JSC. The crash does not happen in dev mode as far as I can tell, I've never been able to trigger it, but then again I've never been able to reproduce reliably it in release mode either.
What we do know from user feedback is that it's seemingly random. There's no clear trigger for the crash. It's possible (but not certain) that it happens in longer sessions. We do have some large MST models that we persist to Firestore with react-native-firebase but if those were the culprit I'd expect them to crash on every save instead of randomly.
We send client logs periodically to a logging service via a firebase cloud function, perhaps there's a situation where we log a particularly large object or have gathered a large volume of logs which then triggers this error -- something I'll investigate. We also use a ton of animations but I'm not sure if that could be related, they're all pretty simple on their own and they're all useNativeDriver: true even if there's a lot of them.
Thanks for the clues and assistance debugging this, it's really been driving us crazy, hopefully we can figure out the root cause and get it patched up. @mhorowitz @tmikov if you can think of anything I should try to trigger this in the app please let me know, I'll try to test it out.

@mhorowitz was looking into it late last night and I believe he made progress. He will post about his findings.

I don't think I learned any more than I already said, except that I now have a standalone (not in an RN app) test case for dynamicFromValue crashing on deeply nested inputs, in both Hermes and JSC. I can put up a gist with the test case source if someone is interested, but I'm not sure how best to run it without our internal tools.
If you want to take a shot at fixing this yourself, the best fix for this is to convert the two functions in https://github.com/facebook/react-native/blob/master/ReactCommon/jsi/jsi/JSIDynamic.cpp to be iterative instead of recursive. This will require a bit more code complexity, but it will no longer depend on the size of the stack to work (the obvious implementations will depend on the heap, instead). I think RN would accept such a PR.
Since this code is built as part of React Native, you'll need to build RN from source if you want to test fixes: https://github.com/facebook/react-native/wiki/Building-from-source

Another pointer, which might make it easier for you to diagnose this locally. I believe, but can't be sure with the data we have, that the complex object in question is passed to the bridge from JS in this code https://github.com/facebook/react-native/blob/e27d656ef370958c864b052123ec05579ac9fc01/Libraries/BatchedBridge/MessageQueue.js#L308, as the argument params. The JS above, in a __DEV__ release, validates that params contains only serializable data. You could modify this validation to measure the maximum depth, and using a debugger or logging, try to understand where the deepest objects come from. This might give you some insight into what's generating very complex objects across the bridge.

@mhorowitz I'd appreciate seeing the test case even if I don't have the tooling to run it.
I'm already building from source to work around a different problem so that's no issue. I don't think I've written any C(++) code since school many years ago so that part may be a bit of a challenge but doable.
I've never been able to trigger this issue in development so I'm not sure if debugging that location would help or not but it's worth a shot. Thanks for pointing me there.
My initial guess is that we debounce sending our logs to the server and there may be a case where some very large or complex data structure gets logged accidentally. It goes from js->native to be sent to a firebase cloud function. I'm going to release a build with our logging and analytics disabled to see if the crash goes away as that's the quickest way I can think of to test that theory.
I'm not very familiar with the internal architecture of RN so I don't fully understand when/why some complex piece of data might be sent across the bridge. We do a _lot_ of animation, all with useNativeDriver: true, there are probably between 3-10 animated values running at any given time. @mhorowitz this is kind of a shot in the dark but do you know of any reason why having many animations looping or running at once with useNativeDriver might trigger this sort of behavior? Being animation heavy is one of the only things I can think of that sets our app apart from most "normal" RN apps.

It's written using the same test framework as used by https://github.com/facebook/react-native/blob/master/ReactCommon/jsi/jsi/test/testlib.cpp

As for animations, I'm not familiar with how they are implemented, so I don't have any insight there.
