User tags in a dynamic trace enabled VM are spread throughout the system
in the same way as seq_trace tokens. This is used by the file module
and various other modules to get hold of the tag from the user process
without changing the protocol.

Using a list rather than a dict() for unified variables saves quite
some time. In particular Dialyzer is a heavy user of t_unify().

erl_bif_types: Fix types for lists:key{search,find,member}/3
Fix build problems on MacOS 10.7 (Lion)
|
|
The types for lists:key{search,find,member}/3 was computed under the
assumption that the key should be matched (=:=) to the keys in the
list, while the actual implementation uses comparison (==).
Thus erl_bif_types:types/4 would wrongly report that
lists:keyfind(42, 1, [{42.0,a}])
would always return 'false'.

Atoms in some occurrences were not correctly quoted when formatted to
strings, for instance by the typer program. Example:
-module(tb).
-export(['UPPERCASE-FUNCTION-NAME'/0, f1/0, f2/0, f3/0]).
-record('UPPERCASE-RECORD-NAME', {x}).
-record(r2, {'UPPERCASE-FIELD-NAME'}).
-type 'UPPERCASE-TYPE-NAME'() :: integer().
'UPPERCASE-FUNCTION-NAME'() -> ok.
f1() -> #'UPPERCASE-RECORD-NAME'{x=1}.
f2() -> #r2{'UPPERCASE-FIELD-NAME'=1}.
-spec f3() -> 'UPPERCASE-TYPE-NAME'().
f3() -> 1.
Given the program above, the output from typer --plt some.plt tb.erl
resulted in the following specs being printed:
-spec UPPERCASE-FUNCTION-NAME() -> 'ok'.
-spec f1() -> #UPPERCASE-RECORD-NAME{x::1}.
-spec f2() -> #r2{UPPERCASE-FIELD-NAME::1}.
-spec f3() -> UPPERCASE-TYPE-NAME().
This commit changes the output to become the following:
-spec 'UPPERCASE-FUNCTION-NAME'() -> 'ok'.
-spec f1() -> #'UPPERCASE-RECORD-NAME'{x::1}.
-spec f2() -> #r2{'UPPERCASE-FIELD-NAME'::1}.
-spec f3() -> 'UPPERCASE-TYPE-NAME'().

This patch makes Dialyzer aware of Erlang's total ordering of terms,
enabling discrepancy detection in cases where e.g. integer() < tuple()
is treated as a comparison that might also return false (when it is
certain to always return true).

This BIF's second parameter is a list of options.
Currently the only allowed option is {minor_version, Version}
where version is either 0 (default) or 1.

code: Optimize purge/1 and soft_purge/1 using check_old_code/1
Add erlang:check_old_code/1
check_process_code/2: Quickly return 'false' if there is no old code
|
|
Add erlang:check_old_code/1 to quickly check whether a module
has old code. If there is no old code, there is no need to call
erlang:check_process_code/2 for all processes, which will save
some time if there are many processes.

This commit is a preparation for introducing location information
(filename/line number) in stacktraces in exceptions. Currently
a stack trace looks like:
[{Mod1,Function1,Arity1},
.
.
.
{ModN,FunctionN,ArityN}]
Add a forth element to each tuple that can be used indication
the filename and line number of the source file:
[{Mod1,Function1,Arity1,Location1},
.
.
.
{ModN,FunctionN,ArityN,LocationN}]
In this commit, the fourth element will just be an empty list,
and we will change all code that look at or manipulate stacktraces.

concat_binary/1 was deprecated in R13B04, but already in
the R10B-2 release, the documentation recommends using
list_to_binary/1 instead.
|
|
An incorrect spec, rpc:yield/1, has been fixed.
|
|
While at it:
1. Moved types in their proper place
2. Did minor cleanups and
3. Took out an unused function

Same functionality provided by string:join/2.

After the addition of unicode_binary() to the file:filename() type,
dialyzer started complaining about erroneous or incomplete specs in some
functions of the 'code' module. The culprit was hard-coded information
in erl_bif_types for functions of this module, which were not updated.
Since these functions have proper specs these days and code duplication
(pun intended) is never a good idea, their type information was removed
from erl_bif_types.
While doing this, some erroneous comments were fixed in the code module
and also made sure that the code now runs without dialyzer warnings even
when the -Wunmatched_returns option is used.
Some cleanups were applied to erl_bif_types too.
