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.
2013-01-09Fix fd leak when using async thread poolFilipe David Borba Manana
When using the async thread pool, if an erlang process asks to open a file and it gets shutdown/killed while the file:open/2 call hasn't returned, it's possible to leak a file descriptor against the target file. This happens because when the file driver is stopped (file_stop() function is called), an async thread is executing, about to execute, or executed already the invoke_open() function. After file_stop() is called, the file_async_ready() function will not run, and this function is responsible for setting desc->fd with the file descriptor that invoke_open() got. The file_stop() call closes desc->fd if it refers to a valid file descriptor, which is not the case here, because this function was called before file_async_ready() could run. This leak is easily reproducile in a GNU/Linux system using the following test code: -module(t). -export([t/1]). t(N) -> 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) -> Name = integer_to_list(N), Server = self(), Pid = spawn(fun() -> Server ! continue, {ok, FdW} = file:open(Name, [raw, write]), {ok, FdR} = file:open(Name, [raw, read]), % Optional close calls, with or without them % it makes no difference. %ok = file:close(FdW), %ok = file:close(FdR), ok end), receive continue -> ok end, exit(Pid, shutdown), loop(N - 1). Running this code with a few iterations is enough to very often notice, with the lsof command, that the beam.smp process is holding forever file descriptors open. This issue doesn't happen if the async thread pool is not used. Example: $ erl +A 4 Erlang R15B03 (erts-5.9.3) [source] [64-bit] [smp:4:4] [async-threads:4] [hipe] [kernel-poll:false] Eshell V5.9.3 (abort with ^G) 1> c(t). {ok,t} 2> os:getpid().

2013-01-09observer: Fix check for graphics contextsDan Gudmundsson
wxWidgets-2.9 seg faults if you try to create a graphics context before the window is shown. With bad timing this can happen. So change the haveGC test to check if the functionality is available without creating the GraphicsContext.
