This + bug has been corrected by changing the behaviour of + erlang:halt/0,1, which should fix the same problem for + other escript-like applications, i.e that data stored in + the output port driver buffers got lost when printing on + a TTY and exiting through erlang:halt/0,1. </p> + <p> The BIF:s erlang:halt/0,1 has gotten improved + semantics and there is a new BIF erlang:halt/2 to + accomplish something like the old semantics. See the + documentation. </p> + <p> Now erlang:halt/0 and erlang:halt/1 with an integer + argument will close all ports and allow all pending async + threads operations to finish before exiting the emulator. + Previously erlang:halt/0 and erlang:halt(0) would just + wait for pending async threads operations but not close + ports. And erlang:halt/1 with a non-zero integer argument + would not even wait for pending async threads operations. + </p> + <p> To roughly the old behaviour, to not wait for ports + and async threads operations when you exit the emulator, + you use erlang:halt/2 with an integer first argument and + an option list containing {flush,false} as the second + argument. Note that now is flushing not dependant of the + exit code, and you can not only flush async threads + operations which we deemed as a strange behaviour anyway. + </p> + <p>Also, erlang:halt/1,2 has gotten a new feature: If the + first argument is the atom 'abort' the emulator is + aborted producing a core dump, if the operating system so + allows. </p> + <p> + Own Id: OTP-9985</p> + </item> + <item> + <p> + Add escript win32 alternative invocation. escript can now + be started as both "escript.exe" and "escript" (Thanks to + Pierre Rouleau)</p> + <p> + Own Id: OTP-9997</p> + </item> + </list> + </section> + +</section> + <section><title>STDLIB 1.18</title> <section><title>Fixed Bugs and Malfunctions</title> |
