epy crashed when changing the size of the terminal

[rekinyz]

got following error msg:

_curses.error: addwstr() returned ERR

That's pretty strange... Somehow I cannot recreate the issue when resizing.

Can you elaborate step by step to reproduce the error?

[rekinyz]

1. installed python 3.9.13 with asdf-vm
2. tested on two different laptops with pure ubuntu and wsl2 respectively.
3. created a clean python 3.9.13 .venv
4. installed epy-reader latest version which is (2022.4.18) with poetry
5. opened up randomly an .epub
6. tried to resize terminal window
7. epy crashed

Traceback (most recent call last):
  File "/home/user/.venv/bin/epy", line 8, in <module>
    sys.exit(main())

Thanks for complete traceback! Will look into that.

Another question, does it work for other epub file?

[rekinyz]

nope, tested on diverse epub files and even with different languages

I also cannot reproduce. In Ubuntu 20.04 with python 3, epy handles resizing terminal beautifully.

Although, in Windows, resizing the terminal garbles the screen and remains garbled when resized back to original size. But I suspect that's a Windows-specific (win-curses) issue.

Having the same issue here, crashes with this book when I turn to content pages, manjaro linux.

This seems to be a bug with python's curses itself: https://bugs.python.org/issue8243

Kinda fixed it for epy version v2023.2.8, so if you guys want to try upgrading it via pip and let me know if the issue still persist.

Thank you for your great work, this issue was fixed.
