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).

2013-01-17global_SUITE: Eliminate redundant registration of 'test_server' processBjörn Gustavsson
global_SUITE registers the name 'test_server' in the global registry for what seems to be only historical reasons. Exactly how it happened is lost in the mists of time, but I think the following is a reasonable reconstruction: * At one point in time, the test_server application started to do a global registration of a 'test_server' process to support embedded systems when the test_server application was run on both a host and a target system. * global_SUITE had to be modified to take the pre-existing 'test_server' registration into account. * When Erlang/OTP switched to using common_test, global_SUITE was modified to register the 'test_server' name itself in commit 8bd07f450816eaaae52d28740d89ead1f930cd02 (since the test_server application does not register the 'test_server' name when run under control of common_test). To slightly reduce the size of global_SUITE, remove the redundant registration and stop expecting 'test_server' to be registered.

2013-01-09Add file:allocate/3 operationFilipe David Manana
This operation allows pre-allocation of space for files. It succeeds only on systems that support such operation. The POSIX standard defines the optional system call posix_fallocate() to implement this feature. However, some systems implement more specific functions to accomplish the same operation. On Linux, if the more specific function fallocate() is implemented, it is used instead of posix_fallocate(), falling back to posix_fallocate() if the fallocate() call failed (it's only supported for the ext4, ocfs2, xfs and btrfs file systems at the moment). On Mac OS X it uses the specific fcntl() operation F_PREALLOCATE, falling back to posix_fallocate() if it's available (at the moment Mac OS X doesn't provide posix_fallocate()). On any other UNIX system, it uses posix_fallocate() if it's available. Any other system not providing this system call or any function to pre-allocate space for files, this operation always fails with the ENOTSUP POSIX error.

2012-08-16Allow mixed IPv4 and IPv6 addresses to sctp_bindxTomas Abrahamsson
Also allow mixed address families to bind, since the first address on a multihomed sctp socket must be bound with bind, while the rest are to be bound using sctp_bindx. At least Linux supports adding address of mixing families. Make inet_set_faddress function available also when HAVE_SCTP is not defined, since we use it to find an address for bind to be able to mix ipv4 and ipv6 addresses.
