[Idle-dev] 回复: [BUG]: Can not save anything on IDLE since v3.8.4!!

[Eason Zhang]

Hi Terry,

Thanks for response again.

I tried to create a new file with "File => New"  on 3.8.5. It's true that can be saved as usual. I will take this advice for temporarily.

Sorry for the inconvenience as you don't know Chinese. I just used numbers, English characters and Chinese characters to test print. It's proved that whatever characters are all cannot be saved.

As you mentioned that this fix will be released on 3.9.0 or later version, isn't it ?

Regards,
Eason

In response to my response about missing 'import io' and the fix on
3.8.5/3.9.0b5, Eason privately sent me
QUOTE"""""""""""""""""""""""""""""""""""""""""""""
Video1 (No bug on v3.8.3):
https://www.screencast.com/users/lonlon29/folders/Default/media/a0626e93-2c1c-4921-9560-955eb6111466

Video2(Bug was found on v3.8.5):
https://www.screencast.com/t/xrbA7bQpRbuZ

System environment:
Windows 8.1 64-bits OS and Windows 7 64-bits OS.
"""""""""""""""""""""""""""""""""""""""""""""""

System has Chinese set as its language.  Video2 shows existing
C:/Users/Administrators/Documents/test.py
containing Chinese characters being edited, saved, and run multiple
times with 3.8.5.  So he is not running into the 3.8.4 no non-ascii
chars bug.

In my response, I said Eason might be running into another issue.
Videa2 continues with Windows 7/8.1 File Explorer > Create New > Text
file* > name 385.py > right click > Edit with IDLE 3.8. (*I cannot read
Chinese but recognize positions of clicks. 'Edit ...' is the English
installed by the python Windows installer.)

I did the same with 'Edit with IDLE 3.9' as for some reason my
installation of 3.8 did not add 'Edit with IDLE 3.8'.  I had the same
no-save problem.  When I tried editing the file from a command line with
C:\Users\Terry>py -3.8 -m idlelib f:/python/a/385.py
I got a traceback in Command Prompt ending with

   File "C:\Programs\Python38\lib\idlelib\iomenu.py", line 252, in
fixnewlines
     text = text.replace("\n", self.eol_convention)
TypeError: replace() argument 2 must be str, not None

I suspect that this is only a Windows issue.  Someone with *nix or Mac
could check.

An immediate fix is to change the condition on the previous line,
iomenu.py, line 251.
         if self.eol_convention not in (None, '', "\n"):
This or a better fix should be in the next release, likely 3.9.0rc1.

A new file created with File => New can be saved as usual.
