------------------------------------------
Summary: lib: cpp: TConnectedClient
Key: THRIFT-5678
URL: https://issues.apache.org/jira/browse/THRIFT-5678
Project: Thrift
Issue Type: Bug
Components: C++ - Library
Affects Versions: 0.17.0, 0.16.0, 0.14.2, 0.14.1, 0.15.0, 0.14.0, 0.13.0
Reporter: Christopher Friedt
In TConnectedClient.h the destructor is non-virtual, which causes the warning
below.
{code:java}
In member function 'void
apache::thrift::server::TServerFramework::disposeConnectedClient(apache::thrift::server::TConnectedClient*)':
lib/cpp/src/thrift/server/TServerFramework.cpp:234:3: warning: deleting object
of polymorphic class type 'apache::thrift::server::TConnectedClient' which has
non-virtual destructor might cause undefined behavior
[-Wdelete-non-virtual-dtor]
234 | delete pClient;
| ^~~~~~~~~~~~~~{code}
Not itself a major problem, but Zephyr CI promotes all warnings to errors,
which causes builds to fail.
TConnectedClient.cpp has the following line of code:
{code:java}
TConnectedClient::~TConnectedClient() = default;{code}
It might be considered a regression. The commit that removed the virtual
qualifier was 042580f53441efe1bc5c80c89351fcb30740659e
Suggested fix is to mark it as virtual and set it to default in the header, and
then delete the definition in the .cpp file.
