Add two new system callbacks Module:system_get_state/1 and
Module:system_replace_state/2 to allow sys:get_state/1,2 and
sys:replace_state/2,3 to operate correctly even if a process is sys
suspended. Modify gen_server, gen_fsm, and gen_event to support the new
callbacks.
If a callback module does not export these functions, then by default the
Misc value (the same as that passed as the final argument to
sys:handle_system_msg/6, and returned as part of the return value of
sys:get_status/1,2) is treated as the callback module's state.
The previous behaviour of intercepting the system message and passing a
tuple of size 2 as the last argument to sys:handle_system_msg/6 is no
longer supported.
Add tests to verify the correctness of sys:get_state/1,2 and
sys:replace_state/2,3 when processes are sys suspended. Add two tests for
modules that implement special processes, one that exports
system_get_state/1 and system_replace_state/2 and one that doesn't.
Much of the credit for this patch goes to James Fish, who reported the
initial problem and implemented much of the fix.

epp: Make it possible to specify a default encoding
|
|
In the next commit, we will need a way to tell epp which the
default encoding should be for files that have no encoding comment.
We could add new open() and parse_file() functions with one
extra argument for the encoding, but there are already too many
variants.
To avoid having to add an additional argument to epp:open() and
epp:parse_file() each time new options are needed, introduce
epp:open/1 and epp:parse_file/2 that takes a property list with
options. Also support the new 'default_encoding' option for specifying
the default encoding for source files.
Thanks to Richard Carlsson for the idea and the implementation
of the new functionality in epp.erl.

erl_lint has since R13B emitted warnings whenever any of the types
arity(), bitstring(), iodata(), or boolean() were re-defined. Now
errors are emitted instead.
|
|
Since Erlang/OTP R16B the linter has not emitted warnings when
built-in types were re-defined. This bug has been fixed.
Thanks to Roberto Aloi for reporting the bug.

Instead of deleting the small file when opening it with
dets:open_file/2 an error message is returned, mimicking the behaviour
when the file is bigger.
open_file/1 has been modified to return the same error message when
the file is small as when the file is bigger.

* hb/dialyzer/deprecate_types/OTP-10342:
Introduce compiler option 'nowarn_deprecated_type'
Improve message about deprecated built-in types
|
|
The deprecation of the built-in types dict/0 and so on had as
side-effect that it was impossible to switch to dict:dict/2 and so on
without getting warnings either in the the previous release (R16B) or
the current one (17.0).
By including the attribute
-compile(nowarn_deprecated_type).
in an Erlang source file warnings about deprecated types can be
avoided in 17.0.
The option can also be given as a compiler flag:
erlc +nowarn_deprecated_type file.erl

Map fields are put in their own function instead of being clauses of expr/3.
Also, invalid map construction expressions now emit one error per ':=' field,
at the location of said field instead of one for the whole expression,
furthermore, such warnings do not stop linting of their key and value
expressions anymore. Ill-formed maps constructions are now also properly
detected in guard expressions.

Thanks to Sam Bobroff for reporting the bug.

Shortcircuiting operators are not real functions and can't be used as
such with erlang:'andalso'(...) and erlang:'orelse'(...).

The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(),
set(), and tid() have been deprecated. They will be removed in OTP 18.0.
Instead the types array:array(), dict:dict(), digraph:graph(),
gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid()
can be used. (Note: it has always been necessary to use ets:tid().)
It is allowed in OTP 17.0 to locally re-define the types array(), dict(),
and so on.
New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2,
queue:queue/1, and sets:set/1 have been added.

Commit dfb4ec804a099b539c91e5643090d8183885e71c attempted to add
a closing parenthesis to the expansion of a funtion of zero arity
if there were no other functions with the same name.
Unfortunately it would add the closing parenthesis in many cases
when there was another function with another name (e.g. to
Mod:module_info/0 even though there is a Mod:module_info/1).
Correct logic for adding parenthesis and add a test case.

Support is also added in tests for giving previous releases in a ct
config file, e.g.

{r16,"/path/to/r16/bin/erl"},
