Multiple 'nil' cannot happen on instruction level.
Map keys are always unique with literals.

Coverage removed by literals.

The crash occurred when systools:make_script/2 raises the
'duplicate_modules' error. Depending on the 'silent' option,
systools_make:format_error/1 is called to either format and display an
error message, or return a tuple containing the error properties.
When displaying a 'duplicate_modules' error message, format_error/1
receives a list of applications providing the same module(s):
[
{{Mod,App1,_}, {Mod,App2,_}},
...
]
However, before this fix, format_error/1 expected the following
structure, leading to a 'function_clause' exception:
[
{{Mod,_,App1,_,_}, {Mod,_,App2,_,_}},
...
]
The crash never occurred with the 'silent' option, because the error and
its properties are returned as is to the caller.

The types of some record fields were wrong. This file uses some module
local format of race warnings and when the analysis is done transforms
this format into the format of general dialyzer warnings. This change
fixes the type declaration of the race_warning field of the #races{}
record which was wrong. In addition, declared the type of the state
field in some other record that, long ago, could not be declared since
mutually recursive types were not supported by Dialyzer's analysis.

As any scheduler process can consume any message we have
to make sure that the message is owned by the scheduler
before returning it in erl_drv_ose_get_signal.

Support for tuple funs was removed in R16B but the documentation for
special processes, sys, and proc_lib in the OTP Design Principles still
showed examples using them, and those examples no longer worked. Fix the
examples to use regular functions instead and fix the documentation to
reflect the changes.

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.

* rickard/runtime-dep/OTP-11773:
Documentation fix

Since our config.h is included in each source file in the zlib
directory, we must make sure that config.h is also included
every time zlib functions are called to ensure that definitions
of types are consistent.
zlib_drv.c did not include config.h, which caused problems on
a MacOS X Leopard system. What happened was that HAVE_UNISTD_H
was not defined when zlib.h was included. When unistd.h is not
known to exist, the type z_off_t will be set to a long (32 bits
on this platform). But when the zlib source files were compiled,
HAVE_UNISTD_H was defined, unistd.h would be included, and
z_off_t would be set to off_t (64 bits; defined in unistd.h).
As a result of the mismatch, calls to the adler32_combine() and
crc32_combine() would pass only 32 bits in the len2 argument when
64 bits were expected.

* hb/dialyzer/guard_constr/OTP-11798:
dialyzer: generalize guard constraints in a new way
|
|
Guard constraints used to be limited to a certain depth, which handled
mutually depending constraints safely, but also sometimes introduced
unnecessary generalizations.
This patch puts no explicit limit upon guard constraints (other than
those that already exist in erl_types), but breaks cycles by replacing
variables with the any() type.
In some cases the old method resulted in more warnings, but since the
limit was quite arbitrary and mutually depending guard constraints are
(very) rare, the new method should been seen as an improvement since
it handles cases that used to make Dialyzer loop or miss warnings.
