Bug ID: 465989
Summary: Extracting a file from .xz archive to partition with
insufficient disk space silently drops data
Classification: Applications
Product: ark
Version: 19.12.3
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: elvis.angelac...@kde.org
Reporter: bugs-kde-account@sillyfreak.space
CC: aa...@kde.org, rthoms...@gmail.com
Target Milestone: ---
SUMMARY
Extracting a large file did not fail despite not all data being extracted. Used
applications were Dolphin and Ark. Extraction was of a file in an *.xz archive;
Ark reported the extracted file size as unknown. The file was extracted from an
archive on an ext4 partition to that same partition.
STEPS TO REPRODUCE
1. get a large enough *.xz archive, e.g.
https://downloads.raspberrypi.org/raspios_lite_arm64/images/raspios_lite_arm64-2022-09-26/2022-09-22-raspios-bullseye-arm64-lite.img.xz
(uncompressed size for that particular file should be 2 009 071 616 bytes)
2. open the archive with Ark, e.g. double-click in Dolphin
3. (observe the free space on the target partition (according to Dolphin))
4. extract the compressed file, e.g. by drag-and-drop to Dolphin, to a
partition with insufficient space
OBSERVED RESULT
The file will grow only up to the free space on the partition, then no more.
After some additional time (presumably complete decompression), the file is
reported as completely extracted.
EXPECTED RESULT
The extraction should be reported as failed due to insufficient disk space.
