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.
2011-05-06io.c: Make io_list_vec_len() less generalBjörn Gustavsson
io_list_vec_len() is slightly more general than it needs to be. Specifically: * The only caller always passes ERL_SMALL_IO_BIN_LIMIT as the value for the bin_limit parameter, so the bin_limit parameter can be eliminated. * The only caller never passes any NULL pointers, so there is no need test the pointers before writing through them.
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.

2011-04-11Fix lost wakeup when process garbage collected by otherRickard Green
2011-04-11Only set status P_WAITING when neededRickard Green
The status of a process was unnecessarily set to waiting before the process was enqueued in a run queue. This bug was harmless up until OTP-R14B01. In OTP-R14B02 erlang:hibernate/3 was fixed (OTP-9125). After the introduction of OTP-9125, the previously harmless process status bug sometimes caused erroneous badarg exceptions from process_info().

heart:get_cmd/0 is documented to return an empty string if the command is cleared. get_cmd/0 returns 2 extra bytes: 1 byte for the trailing null, 1 byte from the op (the op is an unsigned char and 2 bytes are allocated for it in the returned buffer). 1> heart:get_cmd(). {ok,[0,0]} 2> heart:set_cmd("echo hello"). ok 3> heart:get_cmd(). {ok,[101,99,104,111,32,104,101,108,108,111,0,0]} 4> heart:clear_cmd(). ok 5> heart:get_cmd(). {ok,[0,99]}

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.
2011-03-29BEAM loader: Simplify handling of the func_info/3 instructionBjörn Gustavsson
For some historical reason, the transformation of a func_info/3 instruction to the internal i_func_info/4 instruction is more involved than it needs to be. Remove the gen_func_info() function in the loader and use a simple transformation.
