Summary: [С++] Arrow Flight Server / Client cannot be initialized with Ipv6 host Key: ARROW-10475 URL: https://issues.apache.org/jira/browse/ARROW-10475 Project: Apache Arrow Issue Type: Bug Components: C++, FlightRPC Reporter: Zosimova Zhanna We want to support Arrow Flight compatibility protocol in [[https://github.com/ClickHouse/ClickHouse]|ClickHouse]. Our code needs Ipv6 support. In our code I wrote: ``` std::string host = "[::]"; int port = 9993; arrow::flight::Location location; auto status = arrow::flight::Location::ForGrpcTcp(host, port, &location); std::cerr << "Status=" << status.ToString() << std::endl; std::cerr << "Location=" << location.ToString() << std::endl; ``` The output seems to be ok: ``` Status=OK Location=grpc+tcp://[::]:9993 ``` After that I initialized FlightServerBase using method Init(options). In flight library I wrote next 3 lines before [[https://github.com/apache/arrow/blob/master/cpp/src/arrow/flight/server.cc#L825]|code] ``` std::cerr << "Location=" << location.ToString() << std::endl; std::cerr << "Host=" << location.uri_->host() << ", Port=" << location.uri_->port_text() << std::endl; std::cerr << "Host:Port=" << location.uri_->host() << ":" << location.uri_->port_text() << std::endl; ``` The output is: ``` Location=grpc+tcp://[::]:9993 Host=::, Port=9993 Host:Port=:::9993 E1103 03:18:01.978794160 612780 server_chttp2.cc:40] \{"created":"@1604362681.978626229","description":"Name or service not known","errno":-2,"file":"../contrib/grpc/src/core/lib/iomgr/resolve_address_posix.cc","file_line":108,"os_error":"Name or service not known","syscall":"getaddrinfo","target_address":":::9993"} ``` Location returns host without square brackets that must be used in addresses with port. The problem is here: ``` std::stringstream address; address << location.uri_->host() << ':' << location.uri_->port_text(); ``` The same issue is also observed in the client [[https://github.com/ClickHouse-Extras/arrow/blob/master/cpp/src/arrow/flight/client.cc#L845]|code] -- This message was sent by Atlassian Jira (v8.3.4#803005)
