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).

2013-01-21Text representation of a float formatted using given options.Serge Aleynikov
This BIF solves a problem of float_to_list/1 that doesn't allow specifying the number of digits after the decimal point when formatting floats. float_to_list(Float, Options) -> string() Float = float() Options = [Option] Option = {decimals, Decimals::0..249} | {scientific, Decimals::0..249} | compact Returns a string which corresponds to the text representation of a `Float` formatted using given options. When decimals option is specified the returned value will contain at most `Decimals` number of digits past the decimal point. When `compact` option is provided the trailing zeros at the end of the list are truncated (this option is only meaningful together with the `decimals` option). When `scientific` option is provided, the float will be formatted using scientific notation with `Decimals` digits of precision. If `Options` is `[]` the function behaves like `float_to_list/1`. When using `decimals` option and the number doesn't fit in the static internal buffer of 256 bytes the function throws `badarg`.

2013-01-21ssl: Enhance error handlingIngela Anderton Andin
Remove filter mechanisms that made error messages backwards compatible with old ssl but hid information about what actually happened. This does not break the documented API however other reason terms may be returned, so code that matches on the reason part of {error, Reason} may fail.
