* pan/fdmanana/fix_efile_drv_crash: Fix efile_drv crash when using async thread pool Alternative solution to the efile_drv crash on exit OTP-10748
2013-01-23Fix efile_drv crash when using async thread poolFilipe David Borba Manana
When using the async thread pool and compressed files, when an efile driver port instance is shutdown, the efile_drv stop callback closes the file descriptor (a gzFile instance actually) - this is dangerous if at the same time there's an async thread performing an operation against the file, for example calling invoke_read(), which can result in a segmentation fault, or calling invoke_close() which double closes the gzFile and this in turn causes 2 consecutive calls to driver_free() against same gzFile instance (resulting in later unexpected crashes in erl_bestfit_alloc.c for example). The following test program makes the emulator crash when using the async thread pool: -module(t2). -export([t/1]). t(N) -> file:delete("foo.bar"), % Use of 'compressed' option, for creating/writing the file, % is irrelevant. It only matters when opening it later for % reads - a non-compressed file open with the 'compressed' % option goes through an internal gzFile handle (instead of % a plain integer fd), just like a compressed file. %{ok, Fd} = file:open("foo.bar", [raw, write, binary]), {ok, Fd} = file:open("foo.bar", [raw, write, binary, compressed]), ok = file:write(Fd, <<"qwerty">>), ok = file:close(Fd), Pid = spawn_link(fun() -> process_flag(trap_exit, true), loop(N) end), Ref = erlang:monitor(process, Pid), receive {'DOWN', Ref, _, _, _} -> ok end. loop(0) -> ok; loop(N) -> Server = self(), Pid = spawn(fun() -> {ok, Fd} = file:open("foo.bar", [read, raw, binary, compressed]), Server ! continue, % Comment the file:read/2 call to make the file:close/1 call much % more likely to crash or end up causing efile_drv to close twice % the fd (gzFile), which will make the emulator crash later in the % best fit allocator (erl_bestfit_alloc.c). _ = file:read(Fd, 5), file:close(Fd) end), receive continue -> ok end, exit(Pid, shutdown), loop(N - 1).
