[ANNOUNCEMENT] TEST RELEASE: Cygwin 2.7.0-0.1

[ANNOUNCEMENT] TEST RELEASE: Cygwin 2.7.0-0.1

[Corinna Vinschen]

Hi folks,


I uploaded a new Cygwin test release 2.7.0-0.1

Apart from the changes mentioned below, there's another patch in the
loop speeding up network access in scenarios with slower round trip
time (most everything on the internet), but I'm still waiting for
input from the patch provider.

=======================================================================

What's new:
-----------

- Support for /proc/<PID>/environ.

- New API: getentropy, getrandom, NL_LOCALE_NAME.


Bug Fixes
---------

- Fix rename(2) fail with EACCES if newfile is in use.
  Addresses: https://cygwin.com/ml/cygwin/2017-01/msg00108.html

- Always try to write all incoming bytes to blocking pipes, as required
  by POSIX.
  Addresses: https://cygwin.com/ml/cygwin/2017-01/msg00087.html

- Fix handling of Alt-Numpad sequences in console handler.
  Addresses: https://cygwin.com/ml/cygwin/2017-01/msg00135.html

- Fix erasing UTF-8 multibyte characters in cooked mode.
  Addresses: https://cygwin.com/ml/cygwin/2017-01/msg00299.html

=======================================================================

Please test.


Thanks,
Corinna

I came across something today. As we know from previous discussions,
libreadline7-7.0.1-2 fixed Alt codes and pasting of UTF-8. However I noticed
today that it did not fix it in all cases. This pasting will work:

    Ω%

but not this:

    %Ω

Starting with snapshot 20170119 and now release 2.7.0, both cases of pasting are
working. Much thanks.

Under cygwin 2.7.0 this works fine for me in tcsh, bash 4.4.11-2, bash
4.4.12-3 and od, including Alt +f6.  That is, as long as I'm in the
Windows console.  Mintty only supports Alt +f6 or Alt 246 when in
Unicode mode.

Cygwin 2.7.0:

Works in tcsh and dash, even with chcp 65001.  Does not work with
bash for some reason in cp 65001.

Why are you switching to cp 65001, btw?  It's completely unnecessary
for utf-8 to work in the Windows console.  Just stick to the default.

Using the Windows Console:

64 LANG = en_US.UTF-8, LC_ALL =
=> LANG = en_US.UTF-8
64-@@ cygcheck -sv | awk '$1 ~ /^(libreadline.|cygwin|"cygwin1.dll")$/'

cygwin                                  2.7.0-0.1                    OK
libreadline7                            7.0.1-1                      OK

64-@@ chcp.com <==== changed from 437 to 65001 for testing only

libreadline must be the culprit ...

Apologies for the confusion ... the unicode symbol I was pasting in was
the latin small letter o with diaeresis ...

For some reason something went wrong when I composed my e-mail.

I had the same problem. You need to add

    Content-Type: text; charset=UTF-8

http://github.com/svnpenn/a/blob/d7afee6/etc/mailing-list.awk#L45

If you leave this off, if defaults to US-ASCII:

http://tools.ietf.org/html/rfc2046#section-4.1.2

which is insane because US-ASCII only supports 128 characters:

http://wikipedia.org/wiki/ASCII#Overview

I wonder if that's a problem in the Windows console.  In theory the
console codepage should have no influence on Cygwin.  Codepages only
should influence non-Unicode aware applications, but console I/O in
Cygwin is using Unicode throughout.

Weird.

Sorry for delayed response. I knew I had a reason for this, but honestly forgot
what it was. Here is the reason:

    $ cat omega.c
    #include <stdio.h>
    int main() {
      printf("Ω\n");
    }

    $ x86_64-pc-cygwin-gcc -o cygwin.exe omega.c
    $ x86_64-w64-mingw32-gcc -o mingw32.exe omega.c
    $ chcp.com 65001
    Active code page: 65001

    $ ./cygwin.exe
    Ω

    $ ./mingw32.exe
    Ω

    $ chcp.com 437
    Active code page: 437

    $ ./cygwin.exe
    Ω

    $ ./mingw32.exe
    Ω

So everything is normal until you run a mingw32 program with the wrong code
page. You would never notice this with cygwin programs because as you can see
they work with either code page.

This really isn't a Cygwin issue as I see it.  What occurs if you run
your mingw32.exe in a CMD command window?  This may be a mintty issue
but certainly not because of Cygwin itself.  But even the mintty case is
dependent on the results you see in CMD.

Wrong. Somewhere between the Cygwin, Bash and Readline this got messed up:

Which goes to further state that this isn't Cygwin but a library package
used by bash.  Cygwin is the POSIX glue to the packages; I know that
everyone wants to think of the entire set as Cygwin but that isn't
really true.  Cygwin is managing to present these characters without
issue with other packages.

Actually, you are right. Dash is not having this problem, it is specific to
Bash. Eric Blake, can you advise?
