64-bit Windows 10.0.10586. 64-bit perl6 on MoarVM built using MS
Visual Studio 2013 tools. See below for more details.

I noticed[1] that several tests fail if the test script has Unix line
endings instead of Windows. These tests succeed if the test script is
converted using unix2dos.

This is problematic behavior. Tests should pass or fail independently
of the EOL convention used in the script file.

E.g. see test 20 in t\spec\S02-literals\heredocs.t​:

  my $e = q​:to<END>;

END
  is no-r($e), "\n", 'Heredoc one empty line';

This fails with​:

# Failed test 'Heredoc one empty line'
# at t\spec\S02-literals\heredocs.t line 171
# expected​: "\r\n"
# got​: "\n"

That is, when the script source uses Unix line endings, $e contains
"\n", but, because the test is being run on Windows, the comparison
string, "\n" becomes "\r\n". Converting the file with unix2dos fixes
the failures, but that is not a solution. "\n" should not be converted
to "\r\n" behind the scenes in a program. EOL conversion should only
happen at input-output boundaries.

What happens in this and other tests that fail depending on whether
the test script is saved using Unix or Windows line endings is
contrary to decades of convention of doing EOL translation only at
input-output boundaries.

I noticed[1] that several tests fail if the test script has Unix line

Also was fine if you have autoclrf set in Git, fwiw.

This is problematic behavior. Tests should pass or fail independently
of the EOL convention used in the script file.

E.g. see test 20 in t\spec\S02-literals\heredocs.t​:

my $e = q​:to<END>;

END
is no-r($e), "\n", 'Heredoc one empty line';

This fails with​:

# Failed test 'Heredoc one empty line'
# at t\spec\S02-literals\heredocs.t line 171
# expected​: "\r\n"
# got​: "\n"

That is, when the script source uses Unix line endings, $e contains
"\n", but, because the test is being run on Windows, the comparison
string, "\n" becomes "\r\n". Converting the file with unix2dos fixes
the failures, but that is not a solution. "\n" should not be converted
to "\r\n" behind the scenes in a program. EOL conversion should only
happen at input-output boundaries.

What happens in this and other tests that fail depending on whether
the test script is saved using Unix or Windows line endings is
contrary to decades of convention of doing EOL translation only at
input-output boundaries.

For more exploration, see

[1]​: https://www.nu42.com/2015/12/perl6-newline-translation-
botched.html

The logical \n in strings (mirroring logical \n in regexes) didn't work out so well in reality as it did in theory. Now​:

* We do translation of \r\n graphemes to \n on all input read as text except sockets, independent of platform
* We do translation of all \n graphemes to \r\n on text output to handles except sockets, on Windows only
* \n is now, unless `use newline` is in force, always \x0A
* We don't do any such translation when using .encode/.decode, and of course when reading/writing Bufs to files, providing an escape hatch from translation if needed

This hopefully addresses the various issues. Various tests have been updated accordingly.
