我有一個table
進程創建一個pid
爲board
作爲其狀態的一部分go()
。gen_server停止不匹配子進程停止
我測試的是終止該表還終止板。但董事會並沒有按預期停止。
我的測試:
kills_board_test() ->
{ok, Table} = table:go(),
{BoardPid, _ ,_ } = s:s(Table, info),
gen_server:stop(Table),
undefined = process_info(BoardPid).
在table.erl
我實現:
handle_call(stop, _From, State = {Board, _, _}) ->
gen_server:stop(Board),
{stop, normal, shutdown_ok, State};
我的結果是:
> 6>table_test:test(). table_test: kills_board_test (module
> 'table_test')...*failed* in function table_test:kills_board_test/0
> (table_test.erl, line 8)

編輯:
我看到的文字 「終止」 ,但我明白了該站點將在返回之前等待終止完成。
您的意思是做'gen_server:調用(表,停止)''的替代gen_server:停止(表)'? – Dogbert
