In many (not all) cases, the value for the 'I' type will
fit into 32 bits.
|
|
We don't want the packable types listed in two places.
|
|
|
|
|
|
|
|
|
|
Introduce a new 'Q' type, similar to 'P' except that it
can be packed.
|
|
In the 32-bit BEAM emulator, it is only possible to pack
3 register operands into one word. Therefore, the move2
instruction (that has 4 operands) needs two words for its
operands.
Take advantage of the larger wordsize in the 64-bit emulator
and pack up to 4 operands into a single word.
|
|
Giving the beam_makeops script access to the external word
size (=the size of instruction words) will allow it to pack
more operands into a word for the 64 bits emulator.
|
|
In the transformation engine in the loader, an is_eq/1 instruction
is currently always preceded by an is_type/1 instruction. Therefore,
save a word and slight amount of time by combining those
instructions into an is_type_eq/2 instruction.
|
|
|
|
The i_jump_on_val_zero/3 and i_select_tuple_arity/3 instructions
were not disassembled correctly.
|
|
|
|
|
|
|
|
It would only really work in simple case like:
select_val S=q Fail=f Size=u Rest=* => ...
where all operands for a single instruction where bound to
variables, and not for more complicated cases such as:
i_put_tuple Dst Arity Puts=* | put PutSrc => ...
|
|
There was a version of the BEAM loader and emulator that
had two versions of the fmove/2 instruction, one version
that allocated heap space internally and a newer version that
assumed that a previous test_heap/2 instruction had already
allocated the heap space.
Though the allocating fmove/2 instruction is no longer
supported, some vestiges of it still remains.

erts_debug:instructions/0 is useful for finding which specific
instructions that are not used at all.

OTP-9024

Handshake hashes, premaster secret and "public_key_info" does not need
to be saved when the connection has been established. The own certificate is
no longer duplicated in the state.

|
The listen() call can fail due to a variety of conditions, so check
its return value and if it fails, print a suitable debug message if
appropriate and then exit. The exit values used are the same for those
already used for bind() failures: 0 if the error is EADDRINUSE, 1
otherwise.

-------------------------------------------------------------------------
ssl's published documentation states:
ssl_accept(ListenSocket) ->
ssl_accept(ListenSocket, Timeout) -> ok | {error, Reason}
(see http://www.erlang.org/doc/man/ssl.html#ssl_accept-1)
while its code has the specs:
-spec ssl_accept(#sslsocket{}) -> {ok, #sslsocket{}} | {error, reason()}.
-spec ssl_accept(#sslsocket{}, list() | timeout()) -> {ok, #sslsocket{}} | {error, reason()}.
One of the two cannot be right. This should be fixed.
Moreover, I do not see why the spec just mentions list() for the options when the documentation explicitly mentions the options of ssl.

The previous code happened to worked if the select-statment returned
only on entry.

* ao/percept-web-stop-rebased:
Verifies the consistency of stopping behavior.
Fixes a bug found in percept:stop_webserver/1, where it doesn't stop the webserver completely
OTP-9012
|
|
Updated the test case webserver to cover both stopping functions stop_webserver/1 and stop_webserver/0.
|
|
webserver completely
percept:stop_webserver/1 will only stop the httpd service in inets, but not the percept_httpd process. As a result, when trying to start the webserver again it will return {error, already_started}. Test case was updated to simulate this case and fix is included to stop the webserver in a consistent way wether stop_webserver/0 or stop_webserver/1 was used.
