Package: mc Version: 3:4.8.30-1 Dear Maintainer,
If a terminal window's resized at a "bad time", mc's panels seem to keep
their old sizes indefinitely--even I press CTRL-L or navigate to another
directory. Oddly, the command bar at the bottom of the screen ("1Help",
etc.) does seem to be drawn with the proper width, but not on the proper
line. The rest of the interface doesn't react at all.
I sometimes notice this if I navigate into a large directory, and resize
the window while the "spinner" is animating at the top-right corner. It
can be difficult to reproduce once Linux has the data cached.
I've had some luck using an LD_PRELOAD library that hooks readdir() with
a usleep() call inserted. I'll attach that. To use it:
gcc -shared -o readdir-usleep.so readdir-usleep.c
export LD_PRELOAD="$(pwd)/readdir-usleep.so"
cd /var/lib # or something with about 50 files
mc
When mc clears the screen and starts animating the "/" at the top-right,
enlarge the terminal window. I'm using urxvt (rxvt-unicode).
I'm experimenting with an automated version of this test, but don't know
how reliable it will be.
- Michael
