[issue33000] IDLE Doc: Text consumes unlimited RAM, consoles likely not

[Big Stone]

Big Stone  added the comment:

for the record, since summer 2018, idlex-1.18 is compatible again with 
Python-3.6+: the author simply forked the old IDLE library IDLEX was depending 
on.

so IDLEX icon in recent Winpython is"truly" IDLEX again.

Terry J. Reedy  added the comment:

Roger, John may have run IDLE rather than IDLEX.  This issue is about 
documenting the fact that tk Texts do not throw away lines, and will accept 
text until there are memory problems.  (Command Prompt, for instance, only 
keeps the last N lines, where N defaults to 300 (not enough to see a test suite 
run) and is max .)

Roger Serwy  added the comment:

Big Stone: Yes, IDLEX does have a slow memory leak. Please check if this bug is 
happening with IDLE itself.

Terry: Thanks for responding to this. I suggest this issue can be closed.

Terry J. Reedy  added the comment:

Big Stone: thank you for the clarification that IDLEX, and its patching of 
idlelib, is not involved.   WinPython is an independent augmented distribution. 
Your suggestion about its IDLEX icon should be sent to its authors.

[issue33000] IDLE Doc: Text consumes unlimited RAM, consoles likely not

[Big Stone]

Big Stone  added the comment:

WinPython-64bit-3.6.4.0Qt5b4 doesn't in fact includes IDLEX: IDLEX is not 
compatible with Python-3.6+

The "IDLEX" icon of WinPython switches back to "normal" IDLE, when IDLEX is not 
detected. 

As WinPython-3.5 is being deprecated, the icon should be renamed IDLE.

[issue33000] IDLE Doc: Text consumes unlimited RAM, consoles likely not

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I don't know whether memory difference between us is due to IDLEX or Windows 
version or something else, but I don't really care.  The IDLE doc has a section 
"IDLE-console differences".  It should gain a paragraph explain the difference 
between memory-limited tk.Text-based Shell and limited-lines consoles.  For 
Command Prompt, the buffer defaults to a pathetic 300 lines, which is not 
enough for the CPython test suite output.  The max is  for those who 
discover how to enlarge it.  No limit is an advantage for most uses, but not 
for one who fills up memory.

I will also think about a sentence to add to the introductory section about 
development versus production runs.
