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.

These tests start new nodes, and they frequently timed out on some

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.

Appups now only support one major release back, and the tests are
updated accordingly.
Support is also added in tests for giving previous releases in a ct
config file, e.g.
{otp_releases,[{r15,"/path/to/r15/bin/erl"},
{r16,"/path/to/r16/bin/erl"},
{'17',"/path/to/17/bin/erl"}]}.

Prior to this commit, erl_eval did not properly evaluate
erlang:'=='/2 and friends in guard clauses because it
always flattened it to a local call ==/2. This commit
removes the flattening logic while still normalizing old
guards style.

`erl` has tab completion for modules' exported functions but expands
only up to the opening paren. This commit closes that opening paren
in case the function is of arity zero and there is no other function with
the same name. It browses the lists of matches (a 2nd time) for Arity,
on complete match and then decides what to append.

This patch introduces the no_auto_import attribute:
-compile(no_auto_import).
Useful for code generation tools that always use the
qualified function names and want to avoid the auto
imported functions clashing with local ones.
Implementation wise, we chose to have a special flag
'all' to avoid doing many set lookups when checking for
suppression.

dict:size/1 runs in constant time, but orddict:size/1 does not. With

files as delimiters.
While working on a tool that processes Erlang code and testing it against this repo,
I found out about those little sneaky 0xff. I thought it may be of help to other
people build such tools to remove non-conforming-to-standard characters.

When reporting a field redefinition in a record, erl_lint can forget
about some old unused variables.
f() -> X = 1, #r{a=foo,a=bar,a=qux}.
|
|
Variables used in the body of a try expression were marked as unsafe
*and* used, which makes no sense as an unsafe variable can't be used.
Function vtsubtract/2 is used to forget usage of such unsafe variables.

When analyzing complex expressions (i.e. comprehensions, cases, tries,
ifs and receives), erl_lint does not forget about old unused variables
when returning the updated variable table. This causes a bug where old
unused variables are not recorded as such:
t(X, Y) ->
#r{a=[ K || K <- Y ],b=[ K || K <- Y ]}.
As erl_lint uses vtmerge_pat/2 to merge the results of the analysis of
the two list comprehensions, X is marked as used and the warning is not
emitted.
The function vtmerge_pat/2 is used instead of the similar vtmerge/2
which does not mark multiple occurrences of a variable as usage to
handle cases like the following one:
t(X, Y) ->
#r{a=A=X,b=A=Y}.
Other simpler expressions like conses, tuples and external fun
references do not correctly follow this behaviour, e.g. A is not marked
as used in the following code:
t(X, Y) ->
{A=X,A=Y}.
This commit fixes both issues and makes erl_lint not return old unused
variables in updated tables and makes all compound expressions use
vtmerge_pat/2.

Added to re:run and sets the corresponding fields in 'extra' struct
for the PCRE match engine. The result can be viewed by also
setting 'report_errors' when matching.
Some housekeeping was also done...
The offset option also did not properly check for offset's >= 0.
Change nomatch to BADARG when pre-compiled mp() is faked:
By constructing a 5-tuple with faked content but the right data types,
you could do a re:run which returned nomatch when in fact the mp() was
bad. The cheapest solution is to check the return from pcre_exec
better.
Remove unreachable code in erts_bif_re.c:
Replaced tests for things that logically simply
cannot happen with ASSERT.
