[BUG] "input buffer overflow, can't enlarge buffer because scanner uses REJECT" when using error dialog for large text

[itspec-ru]

Rofi version (rofi -v)

Version: 1.7.5

Configuration

https://gist.github.com/itspec-ru/0c5cb29341c5e51bc2a1deb5aaf68c60

Theme

https://gist.github.com/itspec-ru/9fa95059076302b65602461079938966

Timing report

No response

Launch command

rofi -theme bw -markup -e "${text}"

Step to reproduce

preparing Pango Markup Text of a sufficiently large size

text=$(curl "http://wttr.in/Тольятти?lang=ru" | sed "s/[ \t]*$//" | ansifilter --ignore-csi --pango --font="Liberation Mono" --font-size=15)

using error dialog for display text

rofi -theme bw -markup -e "${text}" -theme-str '* {font: "Liberation Mono 15";} window {fullscreen: false; background-color: rgba ( 0, 0, 0, 0.9 ); location: south east; anchor: south east; width:80%; y-offset:-30;}'

Expected behavior

Some time ago it worked and broke after the update.

Actual behavior

an error has occurred
input buffer overflow, can't enlarge buffer because scanner uses REJECT

Additional information

If the same text is first output to a file and truncated, the program will display it correctly.

Using wayland display server protocol

• No, I don't use the wayland display server protocol

I've checked if the issue exists in the latest stable release

• Yes, I have checked the problem exists in the latest stable version

That is a lot of text for an error box, a use case I never expected.
I look at fixing it.

[itspec-ru]

It worked in 2020 and after some update stopped working.

[DaveDavenport]

I think we need a more fundamental fix for this. Passing > 14kbyte as an argument is not the best way to do this.

maybe rofi -e - will read the content from stdin instead, allowing more input.

[DaveDavenport]

rofi -e - now reads from stdin.

[itspec-ru]

Thanks!
Now all works perfect.

I tested both cases. And they both work.

text=$(curl "http://wttr.in/Тольятти?lang=ru" | sed "s/[ \t]$//" | ansifilter --ignore-csi --pango --font="Liberation Mono" --font-size=15)
rofi -theme bw -markup -e "${text}" -theme-str ' {font: "Liberation Mono 15";} window {fullscreen: false; background-color: rgba ( 0, 0, 0, 0.9 ); location: south east; anchor: south east; width:80%; y-offset:-30;}'

works after commit 635fbd0

curl "http://wttr.in/Тольятти?lang=ru" | sed "s/[ \t]$//" | ansifilter --ignore-csi --pango --font="Liberation Mono" --font-size=15
| rofi -theme bw -markup -e - -theme-str ' {font: "Liberation Mono 15";} window {fullscreen: false; background-color: rgba ( 0, 0, 0, 0.9 ); location: south east; anchor: south east; width:80%; y-offset:-30;}'

works after commit 7814da7

[DaveDavenport]

Thanks for testing.
