* bjorn/stdlib/rand-export_seed/OTP-13162:
Correct rand:export_seed/0 when there is no prior seed
|
|
According to the documentation, rand:export_seed/0 should return
'undefined' if the seed has not been intialized. However, it will
create and return a seed. That means that the following code
will not work as expected:
case rand:export_seed() of
undefined -> rand:seen({1,2,3});
_ -> ok
end,
rand:uniform(Range)
|
|
Add parentheses around annotated type union elements in map pair
types. The bug was introduced in Erlang/OTP 18.0.
|
|
Print constraints as 'V :: T' rather than 'is_subtype(V, T)'.
|
|
erl_lint:format_error/1 would crash with a function error if
conflicting types were given. That was most easily noticed in the
shell:
Eshell V7.0.3 (abort with ^G)
1> <<0/integer-binary>>.
*** ERROR: Shell process terminated! ***

The shell command 'rp' prints strings as lists of integers
when pretty printing of lists is 'false'.
|
|
beam_lib:all_chunks/1 and beam_lib:build_module/1 can be useful
for special-purpose stripping, for example to remove the "Line"
chunk.

We'll need a way to limit the size of the crash report produced
by proc_lib:format(). Add format/3, where the third argument is
a depth argument.

A long time ago, errors from the emulator itself was sent as
messages that would end up in the handle_info/2 function.
Those clauses in handle_info/2 can be removed.
The code for handling events tagged 'info' instead of 'info_msg'
can also be taken out.

Optimize the case where we are appending to the end of the binary, use
binary syntax to create binaries with room for expansion in the next
loop, instead of using iolist_to_binary which creates a binary of the
exact size and needs to be copied in each loop.
Also remove support the unused Acc as iolists.

As pointed out by roowe, qlc does not handle errors in early compiler
(scanner, parser) well in OTP 18.0.
|
|
Add support for the Delete, Home and End keys in the Erlang shell.
These keys are ubiquitous on modern keyboards. Having them working
as expected adds to the convenience of working in the shell, since
they are much easier to use than the corresponding Ctrl-{D,A,E} keys.
The implementation is in line with the existing framework of the line
editor and is thus a natural (and minimal) extension.

In OTP 17 it is possible to mix types such as dict:dict() and
dict:dict(_, _) outside of the dict module (and similarly for some
other opaque types in STDLIB), but the results are unfortunately
possibly invalid warnings in users' code. In OTP 18 parameterized
opaque types with the same name but with different number of
parameters are no longer compatible when seen from outside of the
module where the types are declared.
The types in STDLIB have been updated accordingly; for instance
-opaque dict() :: dict(_, _).
has been replaced by
-type dict() :: dict(_, _).

Add new functions erl_parse:type_inop_prec() and
erl_parse:type_preop_prec().
Get rid of paren_type used for parentheses in types.

A bug in supervisor:get_childspec/2 results in
{error, simple_one_for_one} being returned on every call when the
supervisor strategy is simple_one_for_one.
This commit includes a small refactoring which brings together the
two 'start_child' clauses to make the code easier to follow.
|
|
When a simple_one_for_one supervisor is shutting down, if one or more
of its children fail to terminate within the 'shutdown' timeout, then
the following reporting error will occur:
* If there is only one child that fails to exit on time, then no
supervisor report will be generated.
* If more than one child fails to exit on time, then the reporting
of 'nb_children' in the supervisor report will be 1 less than it
should be.

Several people have requested that the assert macros in EUnit should be
moved out to a separate header file. This patch puts them in
stdlib/include/assert.hrl, which gets included by the eunit.hrl file.
Thus, nothing changes for eunit users, but the asserts can now also be
included separately.

With parametrized types and specs, modules using
orddict can be statically checked with dialyzer.
Although orddict have not been builtin types, it is
good and more natural to have its exported types and
specs aligned to builtin types.

* erlang/pr/745:

This is a follow up to commit b5ee5c6.
Similar to function calls, we also need to annotate used types
on call site since this information is used later on when showing
undefined type errors.
Notice we don't need to annotate the type export because
it is an attribute and those are always properly annotated.

If a child of a simple_one_for_one returns ignore from its start
function no longer store the child for any restart type. It is not
possible to restart or delete the child because the supervisor is a
simple_one_for_one.
Previously a simple_one_for_one would crash, potentially without
shutting down all of its children, when it tried to shutdown a child
with undefined pid.
Previous only one undefined pid child was stored in a simple_one_for_one
supervisor no matter how many times the child start function returned
ignore.
