23.0: issue with generated protobuf.pc files (it depends on `utf8_range`)

[kloczek]

Looks like generated protobuf.pc has in Requires utf8_range.

prefix=/usr
exec_prefix=/usr
libdir=/usr/lib64
includedir=/usr/include

Name: Protocol Buffers
Description: Google's Data Interchange Format
Version: 23.0.0
Requires: absl_absl_check absl_absl_log absl_algorithm absl_base absl_bind_front absl_bits absl_btree absl_cleanup absl_cord absl_core_headers absl_debugging absl_die_if_null absl_dynamic_annotations absl_flags absl_flat_hash_map absl_flat_hash_set absl_function_ref absl_hash absl_layout absl_log_initialize absl_log_severity absl_memory absl_node_hash_map absl_node_hash_set absl_optional absl_span absl_status absl_statusor absl_strings absl_synchronization absl_time absl_type_traits absl_utility absl_variant utf8_range

[kloczek]

In generated protobuf-config.cmake I see as well:

# User options
include("${CMAKE_CURRENT_LIST_DIR}/protobuf-options.cmake")

# Depend packages

if(NOT TARGET absl::strings)
  find_package(absl CONFIG)
endif()
if(NOT TARGET utf8_range)
  find_package(utf8_range CONFIG)
endif()

# Imported targets
include("${CMAKE_CURRENT_LIST_DIR}/protobuf-targets.cmake")

# protobuf-generate function
include("${CMAKE_CURRENT_LIST_DIR}/protobuf-generate.cmake")

# CMake FindProtobuf module compatible file
if(protobuf_MODULE_COMPATIBLE)
  include("${CMAKE_CURRENT_LIST_DIR}/protobuf-module.cmake")
endif()

[kloczek]

Just in case I've build protobuf with -D utf8_range_ENABLE_INSTALL=OFF.

[kloczek]

I've added quick hack to remove utf8_range from Requires on rpm package %install stage.
With such product I was able to start testing use generated package on building other packages.
Results:

[..] 

In other words looks likke protobuf 23.0 is not ready to be used.

[kloczek]

Gentle ping .. any update?

I was able to rebuild protobuf-c usimg 22.5 however still on rebuilding libphonenumber, mysql, opencv are failing on missing symbols.

[fowles]

@coryan do you have a moment to take a look at this?

[coryan]

Happy to do a drive-by. It would be useful to know what platform (Linux, Windows, etc.) this was on, and what version of the compiler. Looks like some Linux distro, with GCC.

The dependency on utf8_range

Is utf8_range a hard dependency? If it is, then the install instructions should say so. Consider adding step-by-step instructions to build all the dependencies from source in https://github.com/protocolbuffers/protobuf/blob/main/src/README.md

If it is not a hard dependency, then this:

protobuf/cmake/install.cmake

Line 7 in 56d1b0f

list(APPEND _pc_targets "utf8_range")

Needs to have a conditional:

if (some_variable_enabled_when_utf8_is_required)
    list(APPEND _pc_targets "utf8_range")
endif ()

The broken build for libphonenumber

This error:

/usr/bin/ld: /tmp/ccOihmdo.lto.o: in function `google::protobuf::RepeatedField<int>::GrowNoAnnotate(int, int)':
/usr/include/google/protobuf/thread_safe_arena.h:198: undefined reference to `google::protobuf::internal::ThreadSafeArena::thread_cache_'

was fixed in #12700. I think @fowles already backported that fix to the 22.x and 23.x branches.

The broken build for mysql

This error

/usr/bin/ld: /usr/lib64/libprotoc.so: undefined reference to symbol '_ZN4absl12lts_2023012513base_internal12SpinLockWaitEPSt6atomicIjEiPKNS1_22SpinLockWaitTransitionENS1_14SchedulingModeE'
/usr/bin/ld: /usr/lib64/libabsl_spinlock_wait.so.2301.0.0: error adding symbols: DSO missing from command line

Seems like a missing -labsl*. Most likely mysql is using find_package(protobuf), using the FindProtobuf embedded with CMake and missing all the new deps. That is indeed the case:

https://github.com/mysql/mysql-server/blob/ea7087d885006918ad54458e7aad215b1650312c/cmake/protobuf.cmake#L124

That needs to change to find_package(protobuf CONFIG). See #12292. It is becoming a FAQ, the Protobuf team should consider updating the release notes.

The broken build for opencv

I think in this case the error explains itself:

   79 | #error "C++ versions less than C++14 are not supported."

The opencv library was configured (or maybe defaults to) compile as C++11:

[ 21%] Building CXX object modules/dnn/CMakeFiles/opencv_dnn.dir/opencv-caffe.pb.cc.o
cd /home/tkloczko/rpmbuild/BUILD/opencv-4.7.0/x86_64-redhat-linux-gnu/modules/dnn && /usr/bin/g++ \

I am not familiar with the configuration options for opencv. It may be necessary to use cmake -DCMAKE_CXX_STANDARD=14 ..., or maybe just omit the -DCMAKE_CXX_STANDARD=14 altogether. Most compilers default to C++14 or higher these days. There are very few cases where one needs to explicitly request C++11.

In summary:

• Looks like the version of Protobuf you are using is missing some fixes already in the release branches.
• Maybe there is a bug in the CMake files if utf8_range is not a hard-dependency.
• I think there are multiple opportunities to improve the Protobuf documentation around building and installation.
• mysql needs some patches to use Protobuf >= 22.0.
• How you configure opencv may need some tweaks.

Happy to do a drive-by. It would be useful to know what platform (Linux, Windows, etc.) this was on, and what version of the compiler. Looks like some Linux distro, with GCC.

The dependency on utf8_range

Is utf8_range a hard dependency? If it is, then the install instructions should say so. Consider adding step-by-step instructions to build all the dependencies from source in https://github.com/protocolbuffers/protobuf/blob/main/src/README.md

If it is not a hard dependency, then this:

protobuf/cmake/install.cmake

Line 7 in 56d1b0f

list(APPEND _pc_targets "utf8_range")

Needs to have a conditional:

if (some_variable_enabled_when_utf8_is_required)
    list(APPEND _pc_targets "utf8_range")
endif ()

I dont see any fix for that in 22.x branch v22.5...22.x

The broken build for libphonenumber

This error:

/usr/bin/ld: /tmp/ccOihmdo.lto.o: in function `google::protobuf::RepeatedField<int>::GrowNoAnnotate(int, int)':
/usr/include/google/protobuf/thread_safe_arena.h:198: undefined reference to `google::protobuf::internal::ThreadSafeArena::thread_cache_'

was fixed in #12700. I think @fowles already backported that fix to the 22.x and 23.x branches.

None of the commits from #12700 are on the list
v22.5...22.x

The broken build for mysql

This error

/usr/bin/ld: /usr/lib64/libprotoc.so: undefined reference to symbol '_ZN4absl12lts_2023012513base_internal12SpinLockWaitEPSt6atomicIjEiPKNS1_22SpinLockWaitTransitionENS1_14SchedulingModeE'
/usr/bin/ld: /usr/lib64/libabsl_spinlock_wait.so.2301.0.0: error adding symbols: DSO missing from command line

Seems like a missing -labsl*. Most likely mysql is using find_package(protobuf), using the FindProtobuf embedded with CMake and missing all the new deps. That is indeed the case:

https://github.com/mysql/mysql-server/blob/ea7087d885006918ad54458e7aad215b1650312c/cmake/protobuf.cmake#L124

That needs to change to find_package(protobuf CONFIG). See #12292. It is becoming a FAQ, the Protobuf team should consider updating the release notes.

mysql is not using absl API and error message shows missing symbol in libprotoc -> it points on libprotoc underlinking with some of the absl DSOs.

In summary:

As I've wrote I've tested that with 23.0.

• Maybe there is a bug in the CMake files if utf8_range is not a hard-dependency.
• I think there are multiple opportunities to improve the Protobuf documentation around building and installation.
• mysql needs some patches to use Protobuf >= 22.0.

I disagree. It compiles and linking fails because missing symbols.

Yes. I said "if it is not a hard dependency". But I looked at the code again and it is. That means this:

I've added quick hack to remove utf8_range from Requires on rpm package %install stage.

Was probably not a good idea.

was fixed in #12700. I think @fowles already backported that fix to the 22.x and 23.x branches.

None of the commits from #12700 are on the list v22.5...22.x

I am not sure why that matters since you are testing with 23.0. FWIW, the relevant commit in the 22.x series is 18fae1c and it is there:

v22.4...22.x

The relevant commit in the 23.x series is 1ca4e9c

mysql is not using absl API and error message shows missing symbol in libprotoc -> it points on libprotoc underlinking with some of the absl DSOs.

I am not sure I follow. That is intentional. libprotoc.so depends on the Abseil symbols. Some of the abseil symbols are part of the public API of libprotoc. It is not expected that -lprotoc by itself will be enough. If it did (for example by linking all the absl* libraries into the .so), I think applications that used Abseil and libprotoc at the same time would quickly run into ODR violations.

In summary:

• Looks like the version of Protobuf you are using is missing some fixes already in the release branches.

As I've wrote I've tested that with 23.0.

Thanks that is useful. Could you also share the specific Linux distro and the steps you are using to compile Protobuf? It would make it easier to repro any bugs locally.

• mysql needs some patches to use Protobuf >= 22.0.

I disagree. It compiles and linking fails because missing symbols.

I think you are expecting that linking with just -lprotoc should work. It does not and it is not expected to. The Protobuf team has fixed the pkg-config modules and the CMake config files to add any new -l flags. That should make it easier to migrate build scripts to add the flags where needed.

Build scripts written for Protobuf <= 21.x must be updated to take into account the new dependencies. If a build script (like mysql's) relies on CMake's FindProtobuf module it needs to be updated. That is because FindProtobuf does not know about the new dependencies.

mysql uses that module and that is why the build is missing -l flags.

I also do not think the Protobuf team should (or could) fix the FindProtobuf module. First, because they cannot go back in time and fix the version of that module that already shipped everywhere. Second, because CMake's team plan of record is to migrate to the config files that Protobuf already generates and installs.

I appreciate this is maybe surprising and/or frustrating. But I am not sure what actions are you suggesting.

Trying to figure out why libprotobuf DSO does not provdes `google::protobuf::internal::ThreadSafeArena::thread_cache_' I found another "intersting: thing.

According to

protobuf/cmake/README.md

Lines 296 to 314 in 17a2d53

	## DLLs vs. static linking
	Static linking is now the default for the Protocol Buffer libraries. Due to
	issues with Win32's use of a separate heap for each DLL, as well as binary
	compatibility issues between different versions of MSVC's STL library, it is
	recommended that you use static linkage only. However, it is possible to
	build libprotobuf and libprotoc as DLLs if you really want. To do this,
	do the following:
	* Add an additional flag `-Dprotobuf_BUILD_SHARED_LIBS=ON` when invoking cmake
	* Follow the same steps as described in the above section.
	* When compiling your project, make sure to `#define PROTOBUF_USE_DLLS`.
	When distributing your software to end users, we strongly recommend that you
	do NOT install libprotobuf.dll or libprotoc.dll to any shared location.
	Instead, keep these libraries next to your binaries, in your application's
	own install directory. C++ makes it very difficult to maintain binary
	compatibility between releases, so it is likely that future versions of these
	libraries will *not* be usable as drop-in replacements.

PROTOBUF_USE_DLLS define should be used only on Win.
Going to try to roll back 18fae1c.

[coryan]

PROTOBUF_USE_DLLS define should be used only on Win.

I think the documentation is very much out of date and I filed a bug requesting fixes (see #12787).

Going to try to roll back 18fae1c.

If you compile the library with PROTOBUF_USE_DLLS defined and use it with that undefined you will have an inconsistent definition for this class:

protobuf/src/google/protobuf/thread_safe_arena.h

Lines 264 to 271 in 17a2d53

	#elif defined(PROTOBUF_USE_DLLS)
	// Thread local variables cannot be exposed through DLL interface but we can
	// wrap them in static functions.
	static ThreadCache& thread_cache();
	#else
	PROTOBUF_CONSTINIT static PROTOBUF_THREAD_LOCAL ThreadCache thread_cache_;
	static ThreadCache& thread_cache() { return thread_cache_; }
	#endif

And that macro is defined when CMake creates shared libraries. Both on Windows and other platforms:

protobuf/cmake/libprotobuf.cmake

Lines 30 to 34 in 42b20b3

	if(protobuf_BUILD_SHARED_LIBS)
	target_compile_definitions(libprotobuf
	PUBLIC PROTOBUF_USE_DLLS
	PRIVATE LIBPROTOBUF_EXPORTS)
	endif()

That is what causes the undefined google::protobuf::internal::ThreadSafeArena::thread_cache_ symbol.

Are you sure you are using the correct .pc file when building the downstream dependency? Or if you are not using .pc files and you are using CMake: is the downstream build using the protobuf config (as opposed to the FindProtobuf module)?

[kloczek]

Are you sure you are using the correct .pc file when building the downstream dependency? Or if you are not using .pc files and you are using CMake: is the downstream build using the protobuf config (as opposed to the FindProtobuf module)?

Yes I'm sure.
Generated .pc files have that -DPROTOBUF_USE_DLLS (I've done that without checking possible impact of that kind of change).
Of course reverte 18fae1c caused that it was not possible to build protobuf baceuse other sybols in that case where missing.
Nevertheless looks liks like something is wrong around use that define in some headers.
