erlang:get_stacktrace/0 returns the stacktrace for the latest
exception. The problem is that the stacktrace is kept until the next
exception occurs. If the last exception was a 'function_clause' or a
'badarg', the arguments for the call are also kept forever. The
arguments can be terms of any size (potentially huge).
In a future release, we would like to only allow
erlang:get_stacktrace/0 from within a 'try' expression. That would
make it possible to clear the stacktrace when the 'try' expression is
exited.
The 'catch' expression has no natural end where the stacktrace could
be cleared. The stacktrace could be cleared at the end of the function
that the 'catch' occurs in, but that would cause problems in the
following scenario (from real life, but simplified):
try
...
catch _:_ ->
io:format(...),
io:format("~p\n", [erlang:get_stacktrace()])
end.
%% In io.erl.
format(Fmt, Args) ->
Res = case ... of
SomePattern ->
catch...
...;
SomeOtherPattern ->
%% Output the formatted string here
...
end,
clear_stacktrace(), %% Inserted by compiler.
Res.
The call to io:format() would always clear the stacktrace before
it could be retrieved.
That problem could be solved by tightning the scope in which the
stacktrace is kept, but the rules for how long erlang:get_stacktrace/0
would work would become complicated.
Therefore, the solution we suggest for a future major release of
OTP is that erlang:get_stacktrace/0 will return [] if it is called
outside the 'catch' part of a 'try' expression.
To help users prepare, introduce a warning when it is likely that
erlang:get_stacktrace/0 will always return an empty list, for example
in this code:
catch error(foo),
Stk = erlang:get_stacktrace()
or in this code:
try Expr
catch _:_ -> ok end,
Stk = erlang:get_stacktrace()

Make calls to get_stacktrace/0 future-proof
OTP-14400
|
|
In the future, erlang:get_stacktrace/0 will probably only work
inside a the 'catch' block of a 'try' expression.
Future-proof the code by rewriting the old-style catch to
a try...catch.

The return value of erlang:get_stacktrace/0 is not defined
when called like this:
try Expr of
Pattern ->
erlang:get_stacktrace()
end
Currently, the stacktrace will be from a random earlier error.
In a future release, it may be [].
Note: We can remove the entire 'case' statement because
CTHReason can never be an atom.

stdlib: Add examples for ets:select_replace docs
erts: Fix ets:select_replace with {const, NewTuple}
|
|
|
|
The uncovered clause was introduced in bee8f839296e.
|
|
Enable ets:select_replace to do a generic single object
compare-and-swap operation of any ets-tuple using
a matchspec like this:
[{Old, [], [{const, New}]}]
The only exception when this does not work is if the key
contains maps or atoms looking like variables (like '$1').
|
|
Also test other options that turns off certain optimizations or
instruction sets.
|
|
Functions that can are known be pure can be evaluated at
compile-time if the arguments are literals and if the result is
expressible as a literal.
list_to_ref/1 and list_to_port/1 returns terms that cannot be
expressed as literals, so the optimization is not possible.
The argument for port_to_list/1 is never a literal, so there is
no way to evaluate it at compile-time. Therefore, marking those
functions as pure serves no useful purpose.
Note: list_to_pid/1 *is* marked as pure, but only so that we can test
the code in sys_core_fold that rejects pure functions that evaluate to
at term that is not possible to express as a literal. It is sufficient
to have one pure function of that kind.
