Bug ID: 472716
Summary: Copying a large selection of files (2000+) often does
not copy some of them
Classification: Applications
Product: dolphin
Version: 23.04.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: v19930...@gmail.com
CC: kfm-de...@kde.org
Target Milestone: ---
SUMMARY
Selecting a large number of files and then copying them tends to not copy at
least some without any apparent error or warning message from dolphin. This may
make user erroneously believe that operation (in the sense of copying all files
to destination) succeeded while it actually did not - which is what happened to
me in regards to a large dataset I've been copying.
STEPS TO REPRODUCE
1. Run the following commands in bash to generate a directory with 3000 empty
files:
1.1 mkdir /tmp/dolphin_copy_test_src /tmp/dolphin_copy_test_dst
1.2 cd /tmp/dolphin_copy_test_src
1.3 for ((i=1;i<=3000;i++)); do touch $(uuidgen); done
2. Open Dolphin file manager, preferably from terminal
3. Navigate to /tmp/dolphin_copy_test_src
4. Press Ctrl+A to select all 3000 files in directory
5. Press Ctrl+C to copy files; at this point console will be spammed with
QDBusConnection: error: could not send message to service
"org.freedesktop.portal.Documents" path "/org/freedesktop/portal/documents"
interface "org.freedesktop.portal.FileTransfer" member "AddFiles": Marshalling
failed: Invalid file descriptor passed in arguments
6. Navigate to /tmp/dolphin_copy_test_dst
7. Press Ctrl+V to paste files you've copied
OBSERVED RESULT
Only some files will be copied - target directory will contain less than 3000
files. The exact number I've seen in my tests varies from around 1500 to around
2700. Pasting again will results in the exact same files being copied until one
selects some files to copy again.
EXPECTED RESULT
All 3000 files are copied.
