for normal case.
We still block for default trace and hipe.

An IP address could in some circomstances be converted to a list and then to_lower was applied to it.
So {$A,1,1,1} was changed to {$a,1,1,1} which of course didn't match....

* ingela/inets/cgi-env/OTP-14679:
inets: httpc - fix default timeout in httpc_SUITE
inets: ENV should be a string
|
|
Timeout must be set in suite/0 or init_per_testcase not init_per_group
or init_per_suite
|
|
This is tested by new erts check that will cause badarg when trying to
execute scripts via mod_cgi

Various places that now reject null chars inside strings
- Primitive file operations reject it in filenames.
- Primitive environment variable operations reject it in
names and values.
- os:cmd() reject it in its input.
Also '=' characters are rejected by primitive environment
variable operations in environment variable names.
Documentation has been updated to document null characters
in these types of data as invalid. Currently these operations
accept null chars at the end of strings, but that will change
in the future.

Rewrite a catch expression like this:
catch side_effect(),
...
to:
try
side_effect()
catch
_:_ ->
ok
end,
...
A try/catch is more efficient since no stack trace will be built
when an exception occurs.
|
|
Improve the receive optimization to be able to handle code
such as this:
Ref = make_ref(),
try
side_effect()
catch _:_ ->
ok
end,
receive
%% Clauses that all match Ref.
.
.
.
end
|
|
If a try/catch is used to ignore the potential exception caused by some
expression with a side effect such as:
try
side_effect()
catch _Class:_Reason ->
ok
end,
.
.
.
the generated code will be wasteful:
try YReg TryLabel
%% call side_effect() here
try_end Yreg
jump GoodLabel
TryLabel:
try_case YReg
%% try_case has set up registers as follows:
%% x(0) -> error | exit | throw
%% x(1) -> reason
%% x(2) -> raw stack trace data
GoodLabel:
%% This code does not use any x registers.
There will be two code paths that both end up at GoodLabel, and
the try_case instruction will set up registers that are never used.
We can do better by replacing try_case with try_end to obtain this
code:
try YReg TryLabel
%% call side_effect() here
try_end Yreg
jump GoodLabel
TryLabel:
try_end YReg
GoodLabel:
The jump optimizer (beam_jump) can further optimize this code
like this:
try YReg TryLabel
%% call side_effect() here
TryLabel:
try_end YReg

that checks the construction of exception information. The test is
taken from the compiler SUITE but part of it (the one that constructs
exceptions which differ between BEAM and HiPE) is commented out.
Related to the discussion of #1596.

The try_end and try_case instructions are implemented the same way
(try_case is translated to try_end by the loader).
We can do better than that. We know that try_case will only be executed
when an exception has been caught. Therefore, we know that x(0) is
the non-value and that x(1) through x(3) need to be shifted down to
x(0) through x(2). There is no need to test x(0) before shifting down.
try_end does not need the register shifting code at all.

Especially lldb seems to get very confused when the
same source file is used by two different object files.
|

Bifs that are called through the export entry
using i_call_last could have their cp set to
return_trace, just like any other call. So we
have to unwind the trace stack to get the correct
cp. Not doing this creates a lot of issues for
fprof.

point following the OpCase() label) can safely be packed into the
instruction word.
