Before the beam_validator was added as compiler pass, it was a
standalone module that could analyse existing .beam files and .S
files.
Even though beam_validator has been part of the compiler for many
releases, it still supports the analysis of .beam and .S files.
To reduce the code bloat and to improve coverage of beam_validator,
remove the file/1 and files/1 functions and all associated help
functions. We'll need to update the test suite, since some of the
checked in .S files have errors that beam_validator ignores, but
that will not be accepted when running them throught the compiler
using the 'from_asm' option. In particular, we will need to export
all functions that should be validated (since the beam_clean pass
will remove any function that is not possible to call).

* bjorn/stdlib/string-tokens/OTP-12422:
Optimize string:tokens/2
Modernize and strengthen the test case for string:tokens/2
|
|
We can save some time by reversing the original string
before starting the tokenization.
When there is only one separator, we can save even more time
by treating that case specially so that we don't have to call
lists:member/2 for each character.

* origin/hb/dialyzer/fix_map_type/OTP-12472:
[dialyzer] Fix a bug concerning map() types
|
|
|
|
|
|
There is no need to always introduce a new variable to hold a map.
Maps are novars (constructs that don't export variables).
|
|
In cd1eaf0116190, opt_simple_let_2/6 was updated to do the same
optimizations in 'value' and 'effect' context.
Coalesce the clauses for 'value' and 'effect' context to one to
make it clear that they do the same thing.
|
|
The code for inlining high-order functions from the lists module
is quite annoying when you try to navigate the sys_core_fold
module. Break out the code into its own module.
|
|
Those functions allow us to clean up some more code.
|
|
Introduce access functions to hide the low-level details of how
type information is implemented.
|
|
|
|
Essentially, core_lib:literal_value/1 became useless when literals
were introduced in R12. Since we always create #c_literal{} records
whenever possible, literal_value/1 would *only* succeed when it was
passed a #c_literal{} argument.
|
|
We are about to deprecate core_lib:get_anno/1 and core_lib:set_anno/2,
so we should stop using them in the compiler.
|
|
Attributes must be literals. Since 1fcdcd50, both core_parse and
v3_core guarantees all Core Erlang terms that may be represented as
literals in fact are represented as literals.
Therefore, we no longer need to call core_lib:is_literal/1, but
can test for a #c_literal{} directly.
|
|
This module is the last that uses -include() instead of
include_lib(). With that change, a quick smoke test can
be done simply like this:
PATH=$ERL_TOP/bin:$PATH erlc -W0 *.erl
Without the change, you would also need to add
-I $ERL_TOP/lib/test_server/include
to the command line.

Rename add_scope/2 to sub_add_scope/2 to be similar in naming as
the other functions that operates on #sub{} (in particular,
sub_subst_scope/1). Also, move the definition to be near to the
other sub_* functions.
|
|
Compiling the following function:
f(V) when not (bar and V) -> true; %Line 4
f(_) -> false.
would produce the following warnings:
no_file: Warning: the call to is_boolean/1 has no effect
t.erl:4: Warning: the guard for this clause evaluates to 'false'
t.erl:4: Warning: use of operator '=:=' has no effect
Two of the warnings refer to calls to is_boolean/1 and '=:='/2 which
v3_core added when translating the code to Core Erlang. The only
relevant warning is:
t.erl:4: Warning: the guard for this clause evaluates to 'false'
Suppress the other two warning by marking the compiler-generated
calls with a 'compiler_generated' annotation.
|

Core Erlang annotations are supposed to be a list of terms. v3_core
could temporarily stuff a record in the 'anno' field of a Core Erlang
record. That will cause Dialyzer warnings if we would tighten the
type specs for annotations. (We want to tighten the warnings in order
to catch more real problems.)
Avoid abusing the annotation by wrapping the entire Core Erlang
record in a #isimple{} record.

* maint:
mnesia: Check nodes after protocol negotiation

'dumbbell/mnesia-hang-if-remote-stopped-after-proto-negotiation' into maint
* dumbbell/mnesia-hang-if-remote-stopped-after-proto-negotiation:
mnesia: Check nodes after protocol negotiation
OTP-12473
|
|
During Mnesia startup, after protocol negotiation, the list of connected
nodes is written to "recover_nodes". This list is later used to merge
the schema.
If Mnesia was stopped on a remote node between the protocol negotiation
and the moment the list is stored in "recover_nodes", the remote node
is still considered running: the value of "recover_nodes" stored during
mnesia_down/1 is overwritten. Therefore, this node may be used to
acquire a write lock on the schema in order to perform the merge. In
this case, the remote node never answers to the lock request and Mnesia
hang forever (application:start(mnesia) never returns).
To fix the problem, we check the list one last time and remove from it
all nodes where Mnesia is stopped. And because there is still a chance
for missing mnesia_down event, handle_cast({mnesia_down, ...}, ...)
writes to recover_nodes again, in addition to mnesia_down/1.
|
|
It is allowed in Erlang/OTP 17 to redefine the map() types. However,
Dialyzer did not handle local map() types correctly.
