* richcarl/assert-comments/PR-1224/OTP-14066:
Add comment-versions of assert macros
|
|
For all assert macros in assert.hrl, add corresponding versions with an
additional last Comment argument, assumed to be chardata. If an
exception occurs, it will contain an entry {comment, Comment}, which a
reporting tool may pretty-print for better readability.

* mm/stdlib/ord-docs/PR-1242:
Document the ordering used in ordsets and orddicts
|
|
Right now the exact order of elements is not specified, yet many
programs rely on the ordering being the obvious one - erlang term order.
It is only beneficial to make this an explicit part of the
documentation.

* elbrujohalcon/expand-sup-doc/PR-1233/OTP-14037:
Expand on the behavior of supervisors
|
|
Add additional details on the behavior of supervisors when
reaching maximum restart intensity, as stated by @rvirding
at [Medium](https://goo.gl/XhwpSL)

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.

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...

Add math:floor/1 and math:ceil/1 to avoid unnecessary conversions
in floating point expressions. That is, instead of having to write
float(floor(X)) as part of a floating point expressions, we can
write simply math:floor(X).

* bjorn/eliminate-sys_pre_expand/OTP-13856:
Remove sys_pre_expand
xref: Eliminate use of sys_pre_expand
debugger: Eliminate use of sys_pre_expand
compiler: Eliminate use of sys_pre_expand
shell_SUITE: Eliminate references to sys_pre_expand in comments
qlc_pt: Simplify code because of updated erl_expand_records
Teach erl_expand_records to translate module-less calls
erl_internal: Add add_predefined_functions/1
cover: Remove always stale comment
|
|
As the next step in eliminating sys_pre_expand, teach
erl_expand_records to handle calls without explicit module name. If
such call refer to a BIF or imported function, add an explicit module
name.
That means that any subsequent pass will know that a call without
a module name is always to a local function defined in the module.
|
|
The sys_pre_expand module used to do a lot more (translate records and
funs, for example), but now it does very little. Most of the code is
an identify transformation of the abstract format.
The identity transformation part of the code must be maintained and
kept correct when new forms are added to the abstract format. That
adds to the maintance burden. It also adds (slightly) to compilation
times. Therefore, we want to eliminate sys_pre_expand, moving all of
its (non-identity) transformations to better places.
As a preliminary first step, move the code that adds the pre-defined
functions (such as module_info/0) to a new function in erl_internal.
