[Bug] Firestore fails to link for desktop on macOS Monterey because of unaligned pointers #712

[REQUIRED] Please fill in the following fields:

Pre-built SDK from the website or open-source from this repo: website
Firebase C++ SDK version: 8.6.0
Problematic Firebase Component: Firestore (Auth, Database, etc.)
Other Firebase Components in use: n/a (Auth, Database, etc.)
Platform you are using the C++ SDK on: Mac M1 Max (Mac, Windows, or Linux)
Platform you are targeting: desktop (iOS, Android, and/or desktop)

[REQUIRED] Please describe the issue here:

(Please list the full steps to reproduce the issue. Include device logs, Unity logs, and stack traces if available.)

Firebase 8.6.0 now comes with arm64 universal libraries for Apple Silicon (which is great, thanks). Building for desktop under most circumstances fails to link with "warnings" of unaligned pointers. We have different products that build with slightly different settings, and some fail but some don't. I'm not sure yet whether this is due to using GNU makefile or xcodebuild build systems, or when building our code as static versus dynamic libraries.

Importantly the quickstarts fail.

Googling the error comes up with a lot of results for iOS Firebase, most of which seem to say it was something about the way the Firebase libraries were built.

Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase C++ quickstarts ? Yes
What's the issue repro rate? (eg 100%, 1/5 etc) 100%

What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

Building the firestore quickstart (exact shell commands below under "Relevant Code") results in:

In a CMake build, if I specify -DCMAKE_OSX_DEPLOYMENT_TARGET="10.15" it works. If I don't, it doesn't. So I'm not sure if this actually is because of Apple silicon.

schmidt-sebastian · 2021-11-02T21:04:40Z

I am hitting the same issue on an Intel Mac. I believe this might be an incompatibility with OS X Monterey.

dconeybe · 2021-11-03T04:49:00Z

All of the "pointer not aligned at address" warnings are coming from nanopb-generated files, specifically, the fields arrays. I'd hazard to guess that these warnings started in version 8.4.0 when its dependency on the iOS SDK was upgraded to include firebase/firebase-ios-sdk#8124 (Migrate FieldValue to Protobuf).

Looking, for example, at the first warning (edited for brevity):

ld: warning: pointer not aligned at address 0x10066FB4A (__ZN8firebase9firestore29firestore_BundledQuery_fieldsE + 50 from libfirebase_firestore.a(bundle.nanopb.cc.o))

Unmangling the name, it's referring to the following declaration:

extern const pb_field_t firestore_BundledQuery_fields[4];

here: https://github.com/firebase/firebase-ios-sdk/blob/04b7555228b537a6cbebbc432f1f45d28336ba3d/Firestore/Protos/nanopb/firestore/bundle.nanopb.h#L143

and the definition is

const pb_field_t firestore_BundledQuery_fields[4] = {
    PB_FIELD(  1, BYTES   , SINGULAR, POINTER , FIRST, firestore_BundledQuery, parent, parent, 0),
    PB_ANONYMOUS_ONEOF_FIELD(query_type,   2, MESSAGE , ONEOF, STATIC  , OTHER, firestore_BundledQuery, structured_query, parent, &google_firestore_v1_StructuredQuery_fields),
    PB_FIELD(  3, UENUM   , SINGULAR, STATIC  , OTHER, firestore_BundledQuery, limit_type, structured_query, 0),
    PB_LAST_FIELD
};

here: https://github.com/firebase/firebase-ios-sdk/blob/04b7555228b537a6cbebbc432f1f45d28336ba3d/Firestore/Protos/nanopb/firestore/bundle.nanopb.cc#L40-L45

I'm not sure why the compiler would emit these "fields" arrays unaligned though. Something for us to dig into though.

dconeybe · 2021-11-03T05:09:54Z

It looks like setting the preprocessor define PB_NO_PACKED_STRUCTS will fix this:

/* Define this if your CPU / compiler combination does not support
 * unaligned memory access to packed structures. Note that packed
 * structures are only used when requested in .proto options. */
/* #define PB_NO_PACKED_STRUCTS 1 */

https://github.com/nanopb/nanopb/blob/ab19ecbe1b9f377ab4ee8e762bfe16c39068ad68/pb.h#L16-L19

Looking through this GitHub repository and https://github.com/firebase/firebase-ios-sdk it looks like the nanopb preprocessor defines always come in this group of 3:

PB_FIELD_32BIT=1 PB_NO_PACKED_STRUCTS=1 PB_ENABLE_MALLOC=1

e.g. https://github.com/firebase/firebase-ios-sdk/blob/0e15427fce0c6039d58d6b2ed634df4350599500/FirebaseFirestore.podspec#L118

EXCEPT, for here

target_compile_definitions(
  protobuf-nanopb-static PUBLIC
  -DPB_FIELD_32BIT -DPB_ENABLE_MALLOC
)

in https://github.com/firebase/firebase-ios-sdk/blob/04b7555228b537a6cbebbc432f1f45d28336ba3d/CMakeLists.txt#L243-L246

My hypothesis is that adding -DPB_NO_PACKED_STRUCTS=1 at that spot would fix this. But this begs the question: if two compiler invocations are using different values for PB_NO_PACKED_STRUCTS then we should be seeing horrible, unexplainable crashes and other weird undefined behavior at runtime since DPB_NO_PACKED_STRUCTS affects the memory layout of the protos. But, maybe we're just getting lucky? I'll look into it.

mark-grimes · 2021-11-03T08:20:19Z

...then we should be seeing horrible, unexplainable crashes and other weird undefined behavior at runtime...

I'm not getting as far as runtime, the compiler says these are warnings but refuses to link with them. If -DCMAKE_OSX_DEPLOYMENT_TARGET="10.15" fixes the memory layout rather than just hiding the warnings it'd be fine.

I also tried targeting x86_64 (on Apple silicon) and got the same. In changing to Apple silicon I also went from Big Sur to Monterey, so I agree this is probably a Monterey issue. I'll change the title.

schmidt-sebastian · 2021-11-03T15:36:36Z

@dconeybe There are hundreds of warnings about unaligned pointers. We would have seen them much earlier if these were caused by a change to Firestore.

dconeybe · 2021-11-03T15:41:17Z

Hmm. Well, I'm going to roll a custom build of the C++ SDK with the -DPB_NO_PACKED_STRUCTS=1 fix from firebase/firebase-ios-sdk#8923 and get you two to test it out to see if it fixes the warnings. If it does, it's a super easy fix.

schmidt-sebastian · 2021-11-03T16:16:46Z

firebase/firebase-ios-sdk#8923 removes the warnings and fixes the build for me.

dconeybe · 2021-11-03T17:29:35Z

The fix has been merged into the iOS SDK: firebase/firebase-ios-sdk#8923. Unfortunately, it won't get picked up by the next C++ SDK release, but it will get picked up by the one after that. Once I get a custom build working (it's having issues at the moment) I'll post it here for you to try out and/or use in the interim.

mark-grimes · 2021-11-03T18:43:50Z

To be honest, targeting macOS 10.15 is fine for us in the medium term so I'm in no rush as long as it gets in eventually. I'm happy to test a build if it helps you out though.

dconeybe · 2021-11-05T20:08:36Z

I have a custom build of the C++ SDK that incorporates firebase/firebase-ios-sdk#8923:

https://github.com/firebase/firebase-cpp-sdk/actions/runs/1426820775

Could you try it out and reply back?

mark-grimes · 2021-11-05T23:21:03Z

Will do, although I won't get a chance until Monday.

dconeybe · 2021-11-10T01:12:43Z

@mark-grimes Have you had a chance to see if that custom build from #712 (comment) fixes the build for you?

mark-grimes · 2021-11-10T10:39:00Z

Sorry, got caught up with other things. I've tried the commands in the initial post (i.e. building firebase-quickstart-cpp/firestore/testapp) and it builds fine where it didn't before. I still get the following warnings but I've had these for ages and had no problems running in production:
