Terry J. Reedy added the comment:

Even though the title of #9290 says stdin, the patches are for all std** 
streams, so should cover this.

[issue12967] IDLE RPC Proxy for standard IO streams lacks 'errors' attribute

[Terry J. Reedy]

Terry J. Reedy added the comment:

Thomas, please re-read the messages starting msg145215 where it was decided 
that this is not an issue about setup.py in particular. There appears to now 
only be a problem if IDLE is run without a subprocess, and that option may 
disappear in 3.4 as unneeded.

[Thomas Kluyver]

Thomas Kluyver added the comment:

It seems pretty arbitrary and newcomer-unfriendly to decide that Python doesn't 
support running setup.py inside IDLE.

Exhibit A: confused newcomer trying to install distribute, getting unhelpful 
error message.

Serhiy Storchaka added the comment:

If this issue only about 'errors' attribute of IDLE RPC Proxy for standard IO 
streams, then it should be closed as outdated. If this issue about 'errors' 
attribute of IDLE standard IO streams (even when running IDLE without a 
subprocess), then the patches for issue9290 will solve this issue.

[Roger Serwy]

Roger Serwy  added the comment:

Issue13532 has an applied patch (422242dbce30) for the subprocess that makes 
the stdout, stderr, and stdin inherit from io.TextIOBase. This includes the 
"errors" attribute, albeit set to ''.

The fix does not apply when running IDLE without a subprocess, so the .errors 
attribute will still be missing.

[issue12967] IDLE RPC Proxy for standard IO streams lacks 'errors' attribute

[Glenn Linderman]

Glenn Linderman  added the comment:

So this looks like it might be a simple fix... in issue 1602, there was a patch 
for Windows console for 3.1... sadly not applied then, or 3.2, or 3.3 (yet).  
But in 3.2, the fix sprouted a failure just like this one: the console output 
class would get reported to not have an "errors" attribute when doing an input. 
 A fix there was to add an attribute errors='strict' to the console output 
class.

Here it seems the same symptom sprouted in the same time frame, for a similar 
situation where the output class has been replaced by one that doesn't have an 
errors attribute... so it should grow one...

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Thank you for redirecting this issue. The goal should be to make the proxies 
completely transparent. They mostly are, but occasional issues arise when they 
are not. Sometimes the source of a problem is not clear. I wonder, for 
instance, whether the non-function in IDLE of

>>> print(input())
abc\
abc\

has anything to do with the bidirectional communication or is entirely internal 
to IDLE.

[issue12967] IDLE RPC Proxy for standard IO streams lacks 'errors' attribute

[Ned Deily]

Ned Deily  added the comment:

I don't have a strong opinion about whether running setup.py in IDLE is 
supported.  But that's not the real issue here.  The problem is that the IDLE 
RPC proxy of the standard IO streams is incomplete, in particular, the 'errors' 
attribute of io.TextIOWrapper streams.  Looking back, it appears that the 
`errors` attribute was added to file objects and io streams in 2.6 but support 
for that was not added to IDLE.  I think that should be fixed.
