            Bug ID: 473575
           Summary: Avoid sleep while flushing cache to removable drive
    Classification: I don't know
           Product: kde
           Version: unspecified
          Platform: Archlinux
                OS: Linux
            Status: REPORTED
          Severity: major
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: fgonzalez.neso at gmail.com
  Target Milestone: ---

Today I was copying an ISO image to a Ventoy-enabled USB drive (exfat).
It seems that the file transfer was cached by default, so the file transfer
dialog was closed after the file was cached.
After clicking the secure-remove button, Plasma showed me the message to not
unplug the device until the flush was done.

After 10 minutes (by setting) my computer went to sleep, and after resuming the
flush message was still showing. It would mean that the flush might not finish
prior to sleep.

It would be nice to have a feature to disable sleep while a cached file
transfer is still being done since file corruption might happen.

STEPS TO REPRODUCE
1. Transfer a file to a device with write cache enabled.
2. Wait for the computer to sleep (make sure to set an appropriate time
threshold so the sleep can occur while the flush is still going).
3. Resume the computer and check the flush dialog and/or file corruption.

OBSERVED RESULT
The computer goes to sleep but after resuming, the cache flush is still
ongoing.

EXPECTED RESULT
The computer goes to sleep only after the cache flush has ended.
