2011-08-03Fix binary construction with huge literal sizesBjörn Gustavsson
Constructing binaries using the bit syntax with literals sizes that would not fit in an Uint will either cause an emulator crash or the loading to be aborted. Use the new TAG_o tag introduced in the previous commit to make sure that the attempt to create huge binary literals will generate a system_limit exception at run-time.
2011-08-03Fix construction of <<0:((1 bsl 32)-1)>>Björn Gustavsson
Attempting to construct <<0:((1 bsl 32)-1)>>, the largest bitstring allowed in a 32 bit emulator, would cause an emulator crash because of integer overflow. Fix the problem by using an Uint64 to avoid integer overflow. Do not attempt to handle construction of <<0:((1 bsl 64)-1>> in a 64-bit emulator, because that will certainly cause the emulator to terminate anyway because of insufficient memory.

F_HIBERNATE_SCHED flag that was introduced in b7ecdcd1ae9e11b8f75e must be cleared in hipe_mode_switch as well. Otherwise, processes running HiPE code that hibernate, wake up and then trap into a BIF will not be rescheduled.

2011-05-10Fix overflow in list_to_bitstring/1Björn Gustavsson
Noticed-by: Jon Meredith
2011-05-10Replace io_list_len() with erts_iolist_size()Björn Gustavsson
The io_list_len() function returns an int, where a negative return value indicates a type error. One problem is that an int only consists of 32 bits in a 64-bit emulator. Changing the return type to Sint will solve that problem, but in the 32-bit emulator, a large iolist and a iolist with a type error will both return a negative number. (Noticed by Jon Meredith.) Another problem is that for iolists whose total size exceed the word size, the result would be truncated, leading to a subsequent buffer overflow and emulator crash. Therefore, introduce the new erts_iolist_size() function which returns a status indication and writes the result size through a passed pointer. If the result size does not fit in a word, return an overflow indication.
2011-05-06Make port_command/2 reject non-byte sized bitstringsBjörn Gustavsson
Also rename the fun_to_port/1 test case to outputv_errors/1 and test sending more kinds of bad data to an outputv-enabled driver.
2011-05-04iolist_size/1: Fix truncation of resultBjörn Gustavsson
iolist_size/1 would silently return a truncated result for iolists whose size exceeded the word size. For example: iolist(lists:duplicate(256, <<0:(1 bsl 24)/unit:8>>)). would return 0 (instead of 4294967296 or 1 bsl 32). Rewrite iolist_size/1 to accumulate the size in a bignum if necessary and result the correct result.

2011-05-04binary_SUITE: Remove workaround for avoiding stack overflowBjörn Gustavsson
In older releases of Erlang/OTP, the '=:=' operator could run out of stack if used to compare very deep lists. Since that problem has been fixed, we can remove the workaround used in the deep/1 test case.

2011-03-29Fix duplicate entries in stacktraces after calling certain BIFsBjörn Gustavsson
Calling a BIF thaf is called as a function (such as process_info/{1,2}) would leave a non-zero value in c_p->cp, which would lead to duplicate entries in the stacktrace.

2011-03-24add support for checking if an ERL_NIF_TERM is an exceptionSteve Vinoski
Add the enif_is_exception function to allow callers to determine whether an ERL_NIF_TERM represents an exception. (Currently the only supported exception is badarg since only enif_make_badarg exists, but this will likely be expanded in future releases.) This allows NIF code to call other NIF functions that return ERL_NIF_TERM and properly check to see if the returned terms are exceptions. Without the enif_is_exception function, developers have to create their own means of checking whether a function creates an exception, such as returning boolean success/failure indicators or some other special value indicating that an exception is in effect. The declaration of enif_is_exception in erl_nif_api_funcs.h respects the order of declarations required to keep compatibility on Windows. Add a new test to verify the operation of enif_is_exception. Modify the erl_nif man page to add a description of enif_is_exception and also to clarify the requirements of calling the enif_make_badarg function. If code calls enif_make_badarg, the env passed in gets set with exception information and so the return value of the calling function MUST be the badarg term returned from enif_make_badarg. Also clarify that the result of enif_make_badarg may be passed only to enif_is_exception and not to any other NIF API functions.
