I also fixed the bug reference in the changelog, and feel free to modify the test plan if you don't agree with my changes.
Sponsored for noble, thanks for the debdiff! Uploading libfilezilla_0.46.0-3.1ubuntu0.1.dsc Uploading libfilezilla_0.46.0-3.1ubuntu0.1.debian.tar.xz Uploading libfilezilla_0.46.0-3.1ubuntu0.1_source.buildinfo Uploading libfilezilla_0.46.0-3.1ubuntu0.1_source.changes ** Description changed: [ Impact ] File reading is not correctly performed and leaves the dependent package filezilla in a state where uploading of files causes error and crashes the application. [ Test Plan ] This test needs a graphical environment, so a VM is best. The instructions below assume such an environment for testing is at hand. + You can quickly get such a VM with noble desktop preinstalled with LXD: + lxc launch images:ubuntu/noble/desktop --vm -c limits.memory=3GiB + n-filezilla --console=vga * Create vanilla[1] Virtual Machines (VMs) - Ubuntu 24.04. * set a password for the ubuntu user, or some other user to test: - sudo passwd ubuntu + sudo passwd ubuntu * Install vsftpd and filezilla: sudo apt install vsftpd filezilla * Change configuration to allow uploads: change write_enable to YES in /etc/vsftpd.conf * restart vsftpd sudo systemctl restart vsftpd * create a simple file to upload in the home directory of the test user (ubuntu in this example) echo "Hello from ftp client" > /home/ubuntu/hello.txt To test the fix or reproduce the bug, launch filezilla as a user, and connect to localhost using the password specified earlier. It's best to launch it from a terminal: - filezilla ftp://ubuntu@localhost + filezilla ftp://ubuntu@localhost Use filezilla to upload the "hello.txt" file to the Desktop folder on the "remote" server (which is the same machine). With the bug, filezilla will crash as soon as the upload finishes, with an error like below: (...) wxD-Bus: CPowerManagementInhibitor: Request successful, cookie is 866151098 wxD-Bus: CPowerManagementInhibitor: Requesting idle wxD-Bus: Reply with serial 8 wxD-Bus: CPowerManagementInhibitor: Request successful wxD-Bus: CPowerManagementInhibitor: Requesting busy wxD-Bus: Reply with serial 9 wxD-Bus: CPowerManagementInhibitor: Request successful, cookie is 1438183114 Aborted (core dumped) - - With the fixed packages, the upload will finish normally and filezilla will not crash. - + With the fixed packages, the upload will finish normally and filezilla + will not crash. [ Where problems could occur ] The patch allows for correct operation by changing the IO behaviour and alters no other operation of the application. The patch has negligible risk for the users of this library and the dependent package filezilla. Only filezilla consumes this library and there is no risk to any other library/application. [ Other Info ] None. [1] These are installations that have only Ubuntu repositories and no applications installed other than the default install ones and the package being test. [ Original Description ] filezilla crashes (core dump) while transferring file(s) when connected via SFTP.
