(OTP-8111) Restored supervisor tree so that error propagation will work as intended, although connection processes are set to temporary, instead of permanent with restart times set to 0, and termination of the connection subtree is initiated by a temporary process spawned by ssh_connection_managers terminate. This is done to avoid unwanted supervisor reports. Pherhaps we need some new supervisor functionality. --- lib/ssh/test/ssh_basic_SUITE.erl | 67 +++++++++++++++++++++++++++++++--------- lib/ssh/test/ssh_sftpd_SUITE.erl | 7 +++-- lib/ssh/test/ssh_test_lib.erl | 10 ++++++ 3 files changed, 67 insertions(+), 17 deletions(-) (limited to 'lib/ssh/test') diff --git a/lib/ssh/test/ssh_basic_SUITE.erl b/lib/ssh/test/ssh_basic_SUITE.erl index 8ec037dd8f..012367a6df 100644 --- a/lib/ssh/test/ssh_basic_SUITE.erl +++ b/lib/ssh/test/ssh_basic_SUITE.erl @@ -88,7 +88,7 @@ end_per_testcase(TestCase, Config) when TestCase == server_password_option; UserDir = filename:join(?config(priv_dir, Config), nopubkey), ssh_test_lib:del_dirs(UserDir), end_per_testcase(Config); -end_per_testcase(TestCase, Config) -> +end_per_testcase(_TestCase, Config) -> end_per_testcase(Config). end_per_testcase(_Config) -> ssh:stop(), @@ -108,14 +108,16 @@ all() -> {group, rsa_key}, {group, dsa_pass_key}, {group, rsa_pass_key}, + {group, internal_error}, daemon_already_started, server_password_option, server_userpassword_option]. groups() -> [{dsa_key, [], [exec, exec_compressed, shell, known_hosts]}, - {rsa_key, [], [exec, exec_compressed, shell, known_hosts]}, + {rsa_key, [], [exec, exec_compressed, shell, known_hosts]}, {dsa_pass_key, [], [pass_phrase]}, - {rsa_pass_key, [], [pass_phrase]} + {rsa_pass_key, [], [pass_phrase]}, + {internal_error, [], [internal_error]} ]. init_per_group(dsa_key, Config) -> @@ -138,6 +140,12 @@ init_per_group(dsa_pass_key, Config) -> PrivDir = ?config(priv_dir, Config), ssh_test_lib:setup_dsa_pass_pharse(DataDir, PrivDir, "Password"), [{pass_phrase, {dsa_pass_phrase, "Password"}}| Config]; +init_per_group(internal_error, Config) -> + DataDir = ?config(data_dir, Config), + PrivDir = ?config(priv_dir, Config), + ssh_test_lib:setup_dsa(DataDir, PrivDir), + file:delete(filename:join(PrivDir, "system/ssh_host_dsa_key")), + Config; init_per_group(_, Config) -> Config. @@ -157,6 +165,11 @@ end_per_group(rsa_pass_key, Config) -> PrivDir = ?config(priv_dir, Config), ssh_test_lib:clean_rsa(PrivDir), Config; +end_per_group(internal_error, Config) -> + PrivDir = ?config(priv_dir, Config), + ssh_test_lib:clean_dsa(PrivDir), + Config; + end_per_group(_, Config) -> Config. @@ -268,9 +281,14 @@ shell(Config) when is_list(Config) -> IO = ssh_test_lib:start_io_server(), Shell = ssh_test_lib:start_shell(Port, IO, UserDir), receive + {'EXIT', _, _} -> + test_server:fail(no_ssh_connection); ErlShellStart -> - test_server:format("Erlang shell start: ~p~n", [ErlShellStart]) - end, + test_server:format("Erlang shell start: ~p~n", [ErlShellStart]), + do_shell(IO, Shell) + end. + +do_shell(IO, Shell) -> receive ErlPrompt0 -> test_server:format("Erlang prompt: ~p~n", [ErlPrompt0]) @@ -361,6 +379,9 @@ server_password_option(Config) when is_list(Config) -> {password, "morot"}, {user_interaction, false}, {user_dir, UserDir}]), + + Reason = "Unable to connect using the available authentication methods", + {error, Reason} = ssh:connect(Host, Port, [{silently_accept_hosts, true}, {user, "vego"}, @@ -396,25 +417,20 @@ server_userpassword_option(Config) when is_list(Config) -> {user_dir, UserDir}]), ssh:close(ConnectionRef), - {error, Reason0} = + Reason = "Unable to connect using the available authentication methods", + + {error, Reason} = ssh:connect(Host, Port, [{silently_accept_hosts, true}, {user, "foo"}, {password, "morot"}, {user_interaction, false}, {user_dir, UserDir}]), - - test_server:format("Test of user foo that does not exist.
