What’s new in Portable BleachBit 4.9.1.2886 Alpha
Mar 20, 2025
The following tests apply to both Windows and Linux:
Clean Discord:
In the application menu, click Wipe free space and choose a directory to wipe. Choose any directory on a partition. (You do not need to wipe multiple directories per partition.) Check for a regression: it should succeed without any error messages. Test it on various filesystems, such as NTFS, FAT32, ext2, ext3, ext4, vfat, xfs, and btrfs. Tip: On Linux, you can make extra partitions using a loopback file system. On Windows, use a virtual drive. Tip: to test the condition of wiping a partition that is not full, make a sparse file, to fill it to about 95%. Leave more than 5GB free.
Also, test “wipe free space” on a partition that was already 100% full. See How to fill up a partition.
In the preferences, disable the option for debug logging. Open a terminal and run python3 bleachbit.py –debug –gui (Linux) or bleachbit_console.exe –debug –gui (Windows). You should see many lines such as “automatically hiding” and “Cleaner is not usable on this OS”.
Check that the preferences dialog opens.
Check for extra space in the language selection combobox in the preferences (issue 1764).
In the same combo box, browse the list of language names. Most should be in the format like “English United States (en_US)” with the native name and a language code.
Test the feature to restore window size and position.
Basically, every time BleachBit starts, it should restore the application with the same size, position, and maximized state. First, in the preferences, check the option remember window geometry.
The complexity involves that it may not be possible to honor the request exactly because the number of monitors changed or the resolution of the monitors changed.
Basic test: Change the default position and size, close and restart the application. Verify the window is restored to the same size and position.
Maximized test: Maximize the application, restart it, and verify it was maximized.
Multiple monitors test: Start the application on the second monitor, close the application, disconnect the monitor, and restart the application. Verify it appears on the primary monitor.
Resolution change test: Start the application in the bottom right corner of the primary monitor (not using a secondary monitor), reduce the resolution, and restart the application. Verify the application appears visible (instead of off screen). Tip: either reduce the resolution on your regular display or use a virtual machine like VirtualBox that allows dynamic resolution changes.
Test deleting files and registry keys (on Windows) that cause “access denied” errors, and the error messages should be a single line (instead of multiple lines). Also, on Windows, the slashes should not be doubled like c:\windows\logs\log.txt. To trigger these errors, run BleachBit without administrator privileges (Windows) or sudo (Linux), and then clean system files such as APT (Linux) or Windows Update (Windows). Test variations such as toggling “overwrite files” in the preferences: test it both ways. See issue 1790
Test starting the application when its configuration directory is full. See How to fill up a partition. Test two variations: the bleachbit.ini file did or did not exist before filling the partition. On Windows, the file is located at %appdata%bleachbitbleachbit.ini and on Linux in ~/.config/bleachbit/bleachbit.ini.
Test starting the application when access to its configuration file is locked (but the partition is not full). Scenario 1 is the bleachbit.ini file already exists, and then own it by root sudo chown root ~/.config/bleachbit/bleachbit.ini or equivalent on Windows. In scenario 2, delete it and lock the directory with sudo chown root ~/.config/bleachbit/.
Clean a CleanerML file with a space (871) and dconf (1096). Download test491.xml and put it in the personal cleaners directory. On Windows, it’s %appdata%bleachbitcleaners, and on Linux, it’s ~/.config/bleachbit/cleaners/. Restart BleachBit, and test the new options. Note: dconf applies only to Linux.
Click the application menu and choose system information. Verify it doesn’t crash, and check that the information is correct.
Windows:
Check that the application menu is translated. If your system is in English, go to the preferences and change the language to another language. Restart the application for it to fully take effect.
Either install using the English only installer or delete c:program files (x86)bleachbitsharelocale. Then, verify the preferences dialog opens (1768).
Run `bleachbit_console.exe`, and there should be no error messages such as about dbus (1775) or g_module_open().
Click the application menu and choose “Shred settings and quit” to delete Winapp2.ini, if it was already downloaded. In preferences, enable the option for Winapp2.ini. Restart the application, and verify it downloaded. There should be no error messages, and more cleaning options should appear.
Click the application menu and choose “Make chaff.” Make some files. There should not be an error during the one-time download of the needed data files. If they were already downloaded, use “Shred settings and quit” to delete them, and then repeat the test the downloaded process.
In the preferences, enable the Windows 10 theme. Restart the application, and verify the theme was applied (1782).
Clean System – Windows Updates and verify MMC add-ons still work (1215)
If your system is in English, use the BleachBit preferences to choose another language. Click the application menu and choose “About.” Verify the close button is translated (1474)
