gets crashes Ruby 2.1.3

[Steffen Roller]

with 2.1.3 a script that uses gets crashes.

script1 is ok, script2 crashes after the first key is pushed, before I hit the return key.

my version ruby 2.1.3p242 (2014-09-19 revision 47630) [i386-mingw32]

running on Windows 7 x64

Any idea?

----------------------------

# script1.rb

key = gets

print key

---------------------------

----------------------------

# script2.rb

print "> "

key = gets

print key

---------------------------

Can you provide more details about your encoding? (chcp or changed locale settings in the registry).

Thank you.

The locale is German though.

[Steffen Roller]

Hi Luis,

interesting finding, you were on the right path. My system is configured with German locale, German keyboard, English language.

I tried another system with Windows 2008 R2 - same behaviour. I changed the locale to English (Canada), rebooted et voilà it works.

How can I help to identify the problem? Is there a way to debug?

This is good news! :-)

Can you tell me what is the output of the following script in the affected (non-working) system?

# script3.rb

p Encoding.default_external

p Encoding.default_internal

p Encoding.locale_charmap

[Steffen Roller]

Hi Luis,

here you go:

[C:\src\Ruby\playground\2.1.0-error]script3

#<Encoding:Windows-1252>

nil

"CP1252"

Are you using a console different than cmd.exe? PowerShell? which version? Do you have Ansicon or Console2/ConsoleZ running?

When you reproduced the issue in the other system, was running under the same environment configuration (using the same console, etc.)

I would like to gather more details before we can report this to Ruby-Core.

Thank you.

[Steffen Roller]

Hi Luis,

I'm using TCC, but I ran the tests under CMD.EXE as well. Same behaviour.

I'm using ansicon, but I uninstalled it with ansicon -u and ansicon -U. I also checked the registry to make sure the key was really gone.

I'm using the same configuration on all systems.

As asked to Steffen, can you tell us which Locale is your system setup?

That might provide some ideas.

[Steffen Roller]

Luis,

I believe I sent all information I had. Things haven't chnged since.
I can go back and dig out my emails to have a look how I reproduced the problem.

Was not asking you for additional information, sorry that got phrased that way.

Instead, I'm wondering what is the Locale setting of Michele that could provide us some ideas of the problem.

As I mentioned before, I was unable to reproduce the problem, but my locale was (and always been) English.

It seems there are settings that are affecting internal Unicode/Wide functions of Windows that are not reflected by the encoding information exposed by Ruby.

Want to determine if it happens with other locales and which ones.

Thank you.

[Steffen Roller]

Is your locale in Windows different from your encoding in ruby?
Have you changed some of your locale parameters?

If so - make sure that the Windows locale matches the Ruby locale.

If remove ansicon with command: ansicon -u, ruby work properly.

I think the problem is ansicon, because if acrivate Inject ConEmuHk in Conemu i have same problem.

Until the problem is not resolv i think that i disable ansicon in my console..

[Michele Boscolo]

Sorry the language in my system is Italian.

[Steffen Roller]

My location is now English (United States), my language is German, my Ruby Encoding.internal is CP-1252, charmap CP1252.

The crash still happens under ruby 2.1.3p242 (2014-09-19 revision 47630) [i386-mingw32]

Hello Steffen

Location or Locale? These are two different things. Those are under the same window but have different purposes.

[Steffen Roller]

Hi Luis,

that's how it looks like:
