The current protobuf-c +1.5.0 release does not compile with Google protobuf 26.0 due to the most +recentage breakage. There is a possible workaround involving the Google +protobuf `FileDescriptorLegacy` class, which is documented as: + +// TODO Remove this deprecated API entirely. + +So we probably shouldn't rely on it. + +Instead, this commit obtains the `FileDescriptorProto` corresponding +to the passed in `FieldDescriptor` and interrogates the `syntax` field +directly. This is a single implementation with no version-specific +workarounds. Hopefully this won't break in the next Google protobuf +release. + +I tested the `FieldSyntax()` implementation in this commit across a +number of different Google protobuf releases and found that it worked +(`make && make check`) on all of them: + +- Google protobuf 3.6.1.3 (Ubuntu 20.04) +- Google protobuf 3.12.4 (Ubuntu 22.04) +- Google protobuf 3.21.12 (Debian 12 + Debian unstable) +- Google protobuf 3.25.2 (Debian experimental) +- Google protobuf 26.1-dev +--- + protoc-c/c_helpers.h | 24 ++++++++++++++---------- + 1 file changed, 14 insertions(+), 10 deletions(-) + +diff --git a/protoc-c/c_helpers.h b/protoc-c/c_helpers.h +index 062d330b..be28b601 100644 +--- a/protoc-c/c_helpers.h ++++ b/protoc-c/c_helpers.h +@@ -70,10 +70,6 @@ + #include + #include + +-#if GOOGLE_PROTOBUF_VERSION >= 4023000 +-# include +-#endif +- + namespace google { + namespace protobuf { + namespace compiler { +@@ -173,13 +169,21 @@ struct NameIndex + int compare_name_indices_by_name(const void*, const void*); + + // Return the syntax version of the file containing the field. +-// This wrapper is needed to be able to compile against protobuf2. + inline int FieldSyntax(const FieldDescriptor* field) { +-#if GOOGLE_PROTOBUF_VERSION >= 4023000 +- return FileDescriptorLegacy(field->file()).syntax() == FileDescriptorLegacy::SYNTAX_PROTO3 ? 3 : 2; +-#else +- return field->file()->syntax() == FileDescriptor::SYNTAX_PROTO3 ? 3 : 2; +-#endif ++ auto proto = FileDescriptorProto(); ++ field->file()->CopyTo(&proto); ++ ++ if (proto.has_syntax()) { ++ auto syntax = proto.syntax(); ++ assert(syntax == "proto2" || syntax == "proto3"); ++ if (syntax == "proto2") { ++ return 2; ++ } else if (syntax == "proto3") { ++ return 3; ++ } ++ } ++ ++ return 2; + } + + // Work around changes in protobuf >= 22.x without breaking compilation against + diff --git a/protobuf-c.spec b/protobuf-c.spec index 4099ab5..40203e8 100644 --- a/protobuf-c.spec +++ b/protobuf-c.spec @@ -1,6 +1,6 @@ Name: protobuf-c Version: 1.5.0 -Release: 1mamba +Release: 2mamba Summary: A C implementation of the Google Protocol Buffers data serialization format Group: System/Libraries Vendor: openmamba @@ -8,13 +8,16 @@ Distribution: openmamba Packager: Silvan Calarco URL: https://github.com/protobuf-c Source: https://github.com/protobuf-c/protobuf-c.git/v%{version}/protobuf-c-%{version}.tar.bz2 +Patch0: protobuf-c-1.5.0-protobuf-26.patch License: BSD ## AUTOBUILDREQ-BEGIN BuildRequires: glibc-devel +BuildRequires: libabseil-cpp-devel BuildRequires: libgcc BuildRequires: libprotobuf-devel BuildRequires: libstdc++6-devel ## AUTOBUILDREQ-END +BuildRequires: libprotobuf-devel >= 28.1 Requires: lib%{name} = %{?epoch:%epoch:}%{version}-%{release} %description @@ -37,11 +40,12 @@ Requires: pkg-config %description -n lib%{name}-devel This package contains libraries and header files for developing applications that use %{name}. - %debug_package %prep %setup -q +%patch 0 -p1 -b .protobuf-26 + ./autogen.sh %build @@ -55,9 +59,6 @@ This package contains libraries and header files for developing applications tha %clean [ "%{buildroot}" != / ] && rm -rf "%{buildroot}" -%post -n lib%{name} -p /sbin/ldconfig -%postun -n lib%{name} -p /sbin/ldconfig - %files -n lib%{name} %defattr(-,root,root) %{_libdir}/libprotobuf-c.so.* @@ -78,6 +79,9 @@ This package contains libraries and header files for developing applications tha %doc CHANGELOG.md README.md TODO %changelog +* Wed Sep 18 2024 Silvan Calarco 1.5.0-2mamba +- rebuilt with protobuf 28.1 + * Fri Dec 01 2023 Automatic Build System 1.5.0-1mamba - automatic version update by autodist
