Improve support for native console programs

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start the Win32 Python (not the Cygwin port) inside mintty

What is the expected output? What do you see instead?
The interactive Python prompt should be displayed. Instead, nothing happens
and the shell remains suspended until I press Ctrl-C.

What version of the product are you using? On what operating system?
0.3.5-1

Please provide any additional information below.
Win32 Python is works fine under Console2
(http://sourceforge.net/projects/console/), which is a different Windows
terminal emulator.

Is there any hope for solving this issue?

[mintty]

Yes, you can expect it to be solved with the next cygwin release which supports the new Windows ConPTY API.

@eximius313 You can also download and use the cygwin test builds now by selecting test radio button in cygwin setup. But as they are test builds random crashes may occur.

[eximius313]

I'm using it via GitBash, so it's not that easy ;)

Cygwin 3.1.0 has been released with ConPTY support.

Cygwin 3.1.0 has been released with ConPTY support.

Hey @mintty , i read the whole conversation but still cant figure how to effectively do SetConsoleMode in a git bash, If i fed PipedHandle which is got from GetStdHandle(STD_INP_HANDLE) it would result in InvalidHandle, Also if i get the console handle through CreateFile by CONIN$ and it would not making any changes in ConsoleMode
For ex: I need to disable Echo Mode in git bash, but seems i cant ?

[mintty]

That question is out of scope here. Mintty and bash provide POSIX style programming environments. ConPTY support is available (by cygwin) to support interworking, but if you wish to program Windows console style, you need to get advice elsewhere.

[mintty]

If you have a program that runs in native Windows console (the cmd thing) and does not work in cygwin, you may ask on the cygwin mailing list.

[codesculpture]

Thanks @mintty will reach cygwin then

[mintty]

One further note, as you mentioned git bash: I don't know whether git bash enables ConPTY support by default meanwhile (as MSYS2 does). If not, you could set environment variable CYGWIN=enable_pcon and then start another terminal from the command line to enforce it.

[mintty]

OK, at least my instance of Git Bash does not support ConPTY (workaround see above), so maybe you should give them an issue.

[mintty]

As a persistent workaround, configure it in your home .minttyrc file:
echo ConPTY=on >> ~/.minttyrc

[codesculpture]

@mintty this is actually working, echo ConPTY=on >> ~/.minttyrc. But can i know what is happening here, i dont quite understand where is the actual problem is please?

[mintty]

Console support (mentioned above, ConPTY) is provided by cygwin. It's enabled by default in cygwin and meanwhile MSYS2 but apparently not in Git bash. With the given option, mintty configures it to be enabled by cygwin/MSYS2.

[mintty]

You can also configure ConPTY support by adding MSYS=enable_pcon to file /etc/git-bash.config as described in the mintty wiki.
You can also enable ConPTY support during installation of Git for Windows, late in the "question and answer" game, by clicking the checkbox
Enable experimental support for pseudo consoles.
