Mario Emmenlauer commented on THRIFT-5186:
------------------------------------------

Since updating from master commit 7c4bdf9 to 55680af I get errors in dockerized 
tests on Ubuntu 18.04 vanilla. I've tried to isolate the problem, and I'm under 
the impression that this PR is at fault (commit 9b9567b "THRIFT-5186: Don't 
pass AI_ADDRCONFIG to getaddrinfo()"). When reverting this commit everything 
works again as expected.

With the commit, the errors I get are in multiple tests, all of the form:
{code}
409: Thrift: Tue May 12 11:34:13 2020 TServerSocket::listen() Could not bind to 0
409: unknown location(0): fatal error: in 
"TServerSocketTest/test_bind_to_address":

requested address

> THRIFT-2539 has been reported, and fixed — but for win32 only, for no 
> apparent reason. The exact same problem reproduces on POSIX.
> Namely, when no network interfaces besides {{lo}} (the 127.0.0.1 loopback 
> interface) are up, C++ and Python apps linked with Thrift-generated code, 
> both clients and servers — *crash by throwing an exception*. Even when the 
> intention is exactly to run them on localhost only.
> This happens because Thrift library code for TSocket, TServerSocket, 
> TNonblockingServerSocket calls 
> [{{getaddrinfo()}}|http://man7.org/linux/man-pages/man3/getaddrinfo.3.html] 
> to resolve target hostname to connect to/listen on, into concrete IP address 
> (v4 or v6, whichever the system is configured for). To that call, it *passes 
> the {{AI_ADDRCONFIG}} hint* which effectively turns a localhost-only 
> situation into:
> {quote}{{Could not resolve host for client socket.}}
> {quote}
> and into this (server-side):
> {code:java}
> гру 23 13:52:13 localhost.localdomain systemd[1]: db_cache.service: Main 
> process exited, code=dumped, status=6/ABRT
> гру 23 13:52:13 localhost.localdomain systemd[1]: db_cache.service: Failed

> I fail to understand the original reason to pass that {{AI_ADDRCONFIG}} hint. 
> It shouldn't be there as I see it.
> Further, since Thrift 0.9.2, windows builds of thrift apps don't pass that 
> hint anymore (see THRIFT-2539), and it seems to be okay.
> For comprehension, I'm attaching a sample patch to remove {{AI_ADDRCONFIG}} 
> from {{lib/cpp}} and {{lib/py}}. The main change will be landing via GitHub, 
> per Thrift's contribution process, so please follow there too.
