[ANNOUNCEMENT] Updated: dash-0.5.8-3

[ANNOUNCEMENT] Updated: dash-0.5.8-3

[Eric Blake (cygwin)]

[-- Attachment #1: Type: text/plain, Size: 2173 bytes --]

A new release of dash, 0.5.8-3, has been uploaded and will soon reach a
mirror near you; replacing 0.5.8-2, and leaving the previous version at
0.5.7-1 on 32-bit and 0.5.7-4 on 64-bit.

NEWS:
=====
This is a minor patch release; it incorporates a new cygwin-specific
patch that was accepted into upstream dash.git that allows 'cd c:' to
change directories to '/cygdrive/c' (or however your mount options spell
it) instead of complaining that './c:' doesn't exist.  Of course, you're
still better off using POSIX-y paths to begin with instead of relying on
drive letters, but as this had been requested on the cygwin list in the
past and was a simple enough patch that upstream took it, I don't mind
backporting it now rather than waiting for the next upstream release.

For now, there are no immediate plans of replacing /bin/sh
with dash, but the possibility remains for the future.

See also the upstream documentation in /usr/share/doc/dash/.

DESCRIPTION:
============

DASH is a POSIX-compliant implementation of /bin/sh that aims to be as
small as possible. It does this without sacrificing speed where
possible. In fact, it is significantly faster than bash (the GNU
Bourne-Again SHell) for most tasks.

UPDATE:
=======
To update your installation, click on the "Install Cygwin now" link on
the http://cygwin.com/ web page.  This downloads setup.exe to your
system. Save it and run setup, answer the questions and pick up
'diffutils' in the 'Base' or 'Shells' category (it should already be
automatically selected).  Be sure that you do not have any cygwin
programs running during the upgrade.

DOWNLOAD:
=========
Note that downloads from cygwin.com aren't allowed due to bandwidth
limitations.  This means that you will need to find a mirror which has
this update, please choose the one nearest to you:
http://cygwin.com/mirrors.html

QUESTIONS:
==========
If you want to make a point or ask a question the Cygwin mailing list is
the appropriate place.

A note to let you know ...

The dash interpreter has a minor problem with multi-byte characters ...
.. at least on Cygwin, NOT on Fedora 24.

When the omega symbol is entered, followed by a backspace, the input buffer
is NOT correctly cleared (or so it appears to me).

Executed in Windows Console:
(but similar behaviour when executed using mintty)

64-@@ uname -a
CYGWIN_NT-6.1 Seven 2.7.0(0.306/5/3)  x86_64 Cygwin
(but same behaviour on x86)

64-@@ dash # latest package (0.5.8-3)

# enter alt-234 (omega symbol), followed by a backspace
$
dash: 1: â–’: not found

# enter alt-234
$ echo Ω | xxd
00000000: cea9 0a                                  ...

# enter alt-234, followed by a backspace
$ echo | xxd
00000000: ce0a                                     ..

NOTE: this behaviour already existed BEFORE Corinna made her
modification to cygwin1.dll in order to "please" Steven P.

Henri

Working fine here. Tested with:

    $ cygcheck -sv | awk '$1~/^(dash|cygwin|"cygwin1.dll")$/'
                      "cygwin1.dll" v0.0 ts=2016-12-16 04:55
    cygwin                  2.6.1-1            OK
    dash                    0.5.8-3            OK

and:

    $ cygcheck -sv | awk '$1~/^(dash|cygwin|"cygwin1.dll")$/'
                      "cygwin1.dll" v0.0 ts=2017-01-19 15:16

You may not understand the importance of UTF-8, but we do.

Peculiar ... must be "Henri" problem then :-P

Installed Cygwin afresh ... (Erik, using the official tool! - setup-x86_64.exe)

 - I get the same result (for both the current cygwin1.dll and the modified one)
 - enter alt-234,
   followed by a backspace, followed by a linefeed, results in dash complaining
 - enter alt-234,
   followed by TWO backspaces (which eats part of the prompt), followed by
   a linefeed, leaves dash at peace ...

Could your issues be relevant to differing stty settings?

Ok, I can dup this. In your previous email you did not mention the final
newline. Here is my similar test:

1. echo
2. Alt 234
3. Backspace

Dash result:

    $ echo | od -tcx1
    0000000 316  \n
             ce  0a

Bash result:

    $ echo | od -tcx1
    0000000  \n
             0a

Obviously Bash is not the problem, nor readline as Dash doesnt use readline. So
it appears the issue this time is again with cygwin1.dll, or perhaps the Dash
package.

.. uhm, it appears to me that Windows is the issue here.

As those in the know do not feel inclined to respond, I will provide some
guesses that are my own:

 - in terms of input buffer management, utf-8 encoded characters will not
   be recognized in case of bash and dash ... (they are under Fedora)
    - see the output of stty -a: iutf8 is not present (it is under Fedora)
 - readline provides bash with input buffer management for utf-8 encoded
   characters on Windows (that is why it 'works' in case of bash)
 - bash has support for utf-8 encoded characters ...
   (e.g. ls -l ? will include one-character filenames in case the name is
    made up of only one multi-byte character)
 - dash has no such support ... [1][2]

Consequently, dash is only partly useful, even more so on Windows (as it
would require an additional "helper" on Windows in order to obtain proper
line-editing). Helper? readline, libedit ...

However, I am only guessing ... (only Erik and Corinna can provide expert
details here).

Henri

Yes, that would have been a possibility ... So, I investigated.

I also compared the stty settings with the one I got using Fedora 24. That made
me aware of the 'iutf8' setting (on Linux).

This setting I could not switch on using Cygwin/Windows.

Henri

I'm not quite sure yet but apparently the problem is in the handling of
VERASE in the termios implementation.  In cooked mode it fills a char
buffer with what has been typed.  The code doesn't know if the bytes in
the buffer are UTF-8 chars or just random bytes.  So VERASE erases
exactly one byte, which means, in case of UTF-8 chars it only erases the
last byte of of a mulitbyte character.

It seems the Linux termios implementation is different in that it
still knows which bytes constitute a single keypress and thus knows
how much byte it has to erase.

Ok, here's what happens on Linux:  The termios code support a flag
IUTF8.  This flag determines if the termios code checks for UTF8
characters in the input when performing an ERASE.  It checks if the
IUTF8 flag is set and if so, it checks in a loop if the just erased byte
is a UTF-8 continuation character.  If so, it erases another byte.

(Thank you for responding -- and your effort thus far).

Agreed. One byte or more, depending on the "character" ... (which is
not a problem in case of UTF-8 encoding -- continuation bit).

Of course, the terminal driver must receive the characters encoded in
UTF-8.

Therefore the question is: 'can the same situation be created under
under Windows?' (does Windows provide the required support?)

A second question is: 'is it worth the effort?' Given that bash can
recognize UTF-8 (using readline) ...

.. and the fact that dash does not support multi-byte characters.

Regards,

Henri

This has nothing to do with Windows.  It's the termios implementation
inside Cygwin.  I created a patch introducing the IUTF8 flag as on Linux
as well as a code snippet trying to remove entire utf-8 characters from
the input if the IUTF8 flag is set.  And it's set now by default since
we default to UTF-8 anyway.

Thomas, you may want to check for the IUTF8 flag in upcoming mintty
versions and unset it if character set configured in the mintty options
dialog is != UTF-8.

I uploaded new developer snapshots to https://cygwin.com/snapshots/
with this patch.  I'm also going to release a Cygwin test version
later today.


HTH,
Corinna

And I will be providing a test build of coreutils (for stty) that
exposes IUTF8 to the command line (to be promoted to current once the
cygwin release is).  dash and readline do NOT need to be rebuilt to take
advantage of it (since it is the terminal, not the shell, that is
handling input), although I need to rebuild readline soon because of
some upstream patches that need to be folded in.

Downloaded the snapshots (both x86 and x86_64). Replaced cygwin1.dll.

Repeated my test for both

 - bash --noediting, and
 - dash

on both snapshots.

Now I get the expected result! (UTF-8 characters are being erased)

Thank you.

Henri.

So the flag is always set initially? Also on Linux? Does it (on Linux) 
also have an effect for non-UTF-8 multibyte encodings?
And cannot the Cygwin DLL set the flag to match the locale setting when 
it was invoked?
I can (and will if appropriate) handle the flag in mintty as needed, but 
what if someone calls LC_ALL=.other_encoding dash later within the 
terminal session? I guess the more consistent solution would be to 
handle this in the cygwin DLL.

Yes, yes, and yes.

No.  We're talking about a function in the master side of the tty, while
the applications started in the terminal are on the slave side.

iutf8 is set in Linux by default and by most terminal applications ionly
reset if the LC_CTYPE setting in the environment of the terminal
application is not set to the utf8 codeset.  This is determined at
terminal startup, not by the inferior processes runnin in the terminal.
The applications still can set iutf8 via termios control (or stty(1)).

For mintty I just thought it might be helpful to honor the character set
setting in its options and to default to iutf8 if it's not set.

I am not familiar with the concept of setting termios properties on 
either the master or slave side of a pty. I've only ever set them in the 
client application, including my tests about IUTF8 which worked. Would 
setting on the master side imply it's set for the clients implicitly, 
and can it be changed later, e.g. when mintty character encoding is 
being changed from the Options dialog?
And you say the function of erasing characters on BS is in the master 
side? To be honest, this confuses me. I thought it's a client function, 
like readline() would perform if used (apparently not by dash), which is 
kind of an enhanced version of the tty cooked mode and used to work even 
without the new flag, right?

Will you patch stty as well to address the new flag?

Sure, but it would be better to find a solution that implicitly works in 
all terminals. Isn't it possible to handle this in forkpty()/openpty()?

The readline source code does not mention IUTF8; and neither bash nor
dash need to reference it, because if the tty handling code sets it
correctly for what the terminal is going to display, then the clients
that are read()ing from the tty never even see BS in cooked mode (the
master side of the terminal handles BS before the read() completes in
the slave, if I'm understanding it correctly).

Already patched; coreutils-8.26-2 was promoted to current yesterday.

Does forkpty()/openpty() currently pay attention to environment
variables to even know what encoding is currently in use?  And what's to
say that the environment used to fork the master side will match the
locale settings of the slave process that connects to the pty, so how do
we know whether to default IUTF8 on or off based solely on the slave's
environment, when it is the master that is handling BS and therefore the
master's character encoding that matters for how much BS should erase ?

This does not comply with my (limited) understanding of pty stuff. In 
mintty, forkpty will create a master/slave pty; mintty feeds it on the 
master side, while the client program (usually a shell) reads from the 
slave side. Mintty never handles BS for input, it simply feeds it into 
the pty. "Line disciplines" like cooked mode must be handled on the 
slave side.

Don't know, but maybe it simply should for this purpose, for a 
widely-useful solution.

See above; the master isn't handling BS. But there should be no such 
inconsistency in the case of mintty because master and slave are forked 
from common initial code. I think this consideration is only relevant 
for reattaching programs like screen.

Also, I've tried both options in mintty. Setting the flag on the master 
side has weird effects, initially blocking the terminal process.
Setting it on the slave side works fine. I've uploaded that to the git 
repository.

That was a mistake (got something wrong when testing). It works from 
either side alike.
I've now patched mintty to keep the flag in sync with the character 
encoding, including on later changes (from Options menu or by escape 
sequence).

There's an ESC sequence to change the codeset?  Do you mean the
alternate codeset sequence \e[10m / \e[11m or is there something
more sophisticated?

Oh, that one! Thanks for mentioning, I had overlooked it and fixed 
mintty now to consider it.
> or is there something more sophisticated?
I actually meant to adress 
https://github.com/mintty/mintty/wiki/CtrlSeqs#locale and there is also 
\e%G and \e%@.

I just notice that later changing of the IUTF8 flag from the master side 
does not seem to work on a Window 10 system (although it works 
initially) while it does work on a Windows 7 system. Weird.

Now tested on 2 Windows 7 systems and 2 Windows 10 systems. Does not
work on Windows 10.
Any idea?

Whatever you're observing, there's nothing Windows version-specific
here.  The tcsetattr function indiscriminately copies the incoming
termios structure over.  Maybe the bg_check function fails for some
reason?  Can you strace setting the flag via tcsetattr?  There should be
some output from tcsetattr as well as from fhandler_termios::bg_check.

Can you check?


Thanks,
Corinna

Attached. There are lots of strace output even without interaction. I've 
tried to isolate the switching moment tightly.

You mean the termios_printf trace? How would I activate it (without 
recompiling cygwin)?

Actually, I'm not sure but I think this problem only occurs if mintty is 
started in a non-UTF-8 locale.
If it's started in UTF-8, later switching seems to work.
The strace shows that errno is set to 88 ENOSYS at some place (but I 
don't know where).

Just use the -m option of strace.  Have a look into strace --help, it's
explained quite thoroughly.

Ok, so here you're setting iflags & ~IUTF8

confirmed by bash

And then bash sets iflags again, just to the same values as mintty had
set them before.

And now mintty sets iflags | IUTF8.  Hmm.  Why does it do that here?
It's certainly too late for bash.

I can't see more, but setting and resetting the flag works as expected.

I wonder.  Can't you just start mintty under GDB and debug what happens
in the places it calls tcgetattr/tcsetattr?  You can also see what
tcsetattr actually doe, which is, almost nothing.  At the core it
chooses the tty and just overwrites the termios structure of the tty.
That's all.  You can also see what function call returns ENOSYS then.

Before fiddling around with gdb (which I'm not familiar with, sorry), 
I've made additional observations.
First, the issue occurs regardless of how the terminal is started.
Then, it seems to occur in interactive bash or tcsh only, not in dash, 
or within the following loop started from bash:
while true; do sleep 1; stty -a; done
In the latter cases everything works as expected.
Maybe it's readline() trying to keep the flag consistent with its locale?
(If that's the case, it still doesn't explain why it only fails on 
Windows 10.)
