2013-01-15Implement ./otp_build configure --enable-silent-rulesAnthony Ramine
With silent rules, the output of make is less verbose and compilation warnings are easier to spot. Silent rules are disabled by default and can be disabled or enabled at will by make V=0 and make V=1.
2013-01-15Fix LM_TRY_ENABLE_CFLAG to use correct environmentBjörn-Egil Dahlberg
LM_TRY_ENABLE_CFLAG takes which environment variable should be updated but only CFLAGS was updated. Though CFLAGS is the normally the intended variable, others may be used. For instance CXXFLAGS.

2013-01-10Make trace_local_SUITE work without the reverse eta conversionAnthony Ramine
The exceptions tracing tests look for {trace_local_SUITE,exc,2} in stacktraces to strip them and compare them to the excepted result, the removal of the reverse eta conversion renames '-exception_test/3-fun-0-' to exc and thus confuses the stripping code. This commit fix this by not using `fun exc/2` but `fun (F, As) -> exc(F, As) end` instead, which was what the reverse eta conversion was doing.

* Default to 'no' for finding a working fallocate
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().

2013-01-08escript to accept emulator arguments when script file has no shebangMagnus Henoch
According to the documentation, if the second or third line in a script starts with %%!, then escript will use the rest of the line as emulator options. However, previously this was only the case if the first line started with #!. This change removes that check, and unconditionally uses the %%! line if present.

2012-12-20erts,hipe: Make hipe compiler ask running emulator about process struct offsetsSverker Eriksson
Changes in "struct process" has made native code more depenedent on if the executing emulator is smp enabled or not. This commit will make a default built hipe compiler (without -xcomp) to ask the running emulator about process struct offsets. This will make native code work (again) as long as the same emulator is used for compilation as well as execution of the native code.

2012-12-14erts: Reduce max heap sizesBjörn-Egil Dahlberg
Reduces max heap sizes to max addressable memory space. In reality this could be even less since we need at least twice as much adressable memory to do a garbage collection. The rest of the system also uses memory thus further constraining heap memory space and in the 64 bit case we really only have 48 bits mappable memory.
