Cannot print long characters in one line at terminal. ptvsd upgrade is required.

Environment data

• VS Code version: 1.41.1
• Extension version (available under the Extensions sidebar): 2019.11.50794
• OS and version: Windows 10 Education 10.0.18362 Build 18362
• Python version (& distribution if applicable, e.g. Anaconda): Python 3.7.1 32bit
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): N/A

Expected behaviour

Expect to print 10 'C’s at end of line.

Actual behaviour

It only prints ‘A’. So I think there are maximum character size when print one line.

Steps to reproduce:

1. Write below code & save it.

s = 'A' * 0x4000 + 'C' * 10
print(s)

1. Press Ctrl + F5 to run this file without debugging.

2. You can see the terminal output which there is no ‘C’.

##########Linting Output - pylint##########

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

Output from Console under the Developer Tools panel (toggle Developer Tools on under Help; turn on source maps to make any tracebacks be useful by running Enable source map support for extension debugging)

There is no error log when running python code.

But in Debug Console, there exists 10 'C’s.

@karthiknadig transfer this problem to ptvsd repository.

The collaborator says this issue is fixed in ptvsd 5.X version. So, could you update ptvsd version from 4.3.2 to 5.X?

Hi @humit0 👋 Thank you for reaching out and mentioning the original issue on the ptvsd repo.

ptvsd 5.0 is currently enabled as an experiment for a small subset of users, and we plan on rolling it out for all users in an upcoming release, so please hang tight until we release it.

Thanks!
