Description Trowe 2024-06-16 12:57:01 UTC
STEPS TO REPRODUCE
1. Open Dolphin
2. Connect to SFTP server
3. Edit the file from Dolphin
4. Open it from the host and you will see that it's corrupt

OBSERVED RESULT
Can't open the file anymore it's corrupt.

EXPECTED RESULT
Edited version of the file

SOFTWARE/OS VERSIONS
Arch Linux/Hyprland

ADDITIONAL INFORMATION
I'm using E-Trail FiveM hosting.
When I open and edit the file with Dolphin file is corrupted.
Doing the same thing in Nautilus or some other SFTP client works just fine.

I am experiencing similar  issues, when i copy an executable file to the server it gets corrupted, causing segfault when i try to run it.

Works find with other sftp clients.

I am also on Arch (EndeavourOS).

sftp: account for maximum request length when using sftp_aio

As stated in the libssh documentation, AIO functions cap the allowed
length per request. Account for that by breaking up into multiple
requests when necessary.
