Jump functions returns the state after performing jump calculation to a
rand module internal state, which is equivalent to perform a large
number of calls of calculating new states for XorShift*/+ algorithms.
This commit add jump functions for exsplus and exs1024 algorithms, and a
wrapper function jump/1. The wrapper function will cause error with
reason "not_implemented" if the jump function for the algorithm is not
implemented.
This commit adds following new functionalities:
- Add new functions rand:jump/0 and rand:jump/1
- Add the member jump to type alg_handler(), a fun for performing
the jump function
- Add jump functions for exsplus, equivalent to 2^64 calls
- Add jump functions for exs1024, equivalent to 2^512 calls
- Revise seed_put/1, seed/1, seed/2
See <https://github.com/erlang/otp/pull/1235#discussion_r86950557>
- Add dummy jump function for exs64 calling
erlang:error(not_implemented)
- Add jump function test cases as follows:
* Add Common Test group reference_jump
* Add tests for jump/0 to reference_jump_procdict/1
* Rename tests for jump/1 to reference_jump_state/1
* Rename gen_jump/1 to gen_jump_1/1
* Add Common Tests reference_jump_procdict and reference_jump_state
to the group reference_jump
- Add jump function documentation
This commit also changes the Copyright year for Kenji Rikitake's code
from 2015 to 2015-2016.

Optimize sets:add_element/2 when adding an element that is already present, and
sets:del_element/2 when the element to be deleted is not present. This optimization
can make certain operations, such as sets:union/2 with many overlapping elements,
up to two orders of magnitude faster.

This makes proc_lib behaves like a normal process as far
as the propagation of exceptions is concerned.
Before this commit, the following difference could be
observed:
6> spawn_link(fun() -> ssl:send(a,b) end).
<0.43.0>
7> flush().
Shell got {'EXIT',<0.43.0>,
{function_clause,
[{ssl,send,[a,b],[{file,"..."},{line,275}]}]}}
ok
8> proc_lib:spawn_link(fun() -> ssl:send(a,b) end).
<0.46.0>
9> flush().
Shell got {'EXIT',<0.46.0>,function_clause}
After this commit, we get the following instead:
3> flush().
Shell got {'EXIT',<0.61.0>,
{function_clause,
[{ssl,send,[a,b],[{file,"..."},{line,275}]},
{proc_lib,init_p,3,[{file,"..."},{line,232}]}]}}
The stacktrace will show minor differences of course
but the form is now the same as without proc_lib.
The rationale behind this commit is that:
* We now have a single form regardless of how the process
was started
* We can use the stacktrace to programmatically alter behavior
(for example an HTTP server identifying problems in input
decoding to send back a generic 400, or a 500 otherwise)
* We can access the stacktrace to print it somewhere (for
example an HTTP server could send it back to the client
when a debug mode is enabled)

Do not start an event timer unless there are no enqueued events.
|
|
Handling of timers and timeouts has been cleaned up
and generalized.
Semantic change regarding state timeout zero:
Previously if one state caused a state timeout zero and
managed to stay in the same state to insert additional
timeout zero(s) in the next state callback invocation, then
there would be only one timeout zero event. The mindset
was that the machine was faster then the timeout zero.
This has changed with the mindset that all state callback
invocations should be independent, so now the machine will
get one state timeout zero event per started state timeout
zero.
Note that just using zero timeouts is fairly esoteric...

Running 'dbg:fun2ms(fun([]) -> return_trace() end' resulted in an error
"dbg:fun2ms requires fun with single variable or list parameter"
But the empty list is actually a list and it is a valid value as a
match-spec head (matching on arity-0 functions).
Although its practical use is questionable this commit eliminates a
small limitation of ms_transform which is not present in the match-spec
grammar.
