Dataloss Bug in Latest Windows Installer Builds Can Delete Contents of Program Files Folder

Thursday February 5th, 2004

A serious bug in the latest Windows installer builds of the Mozilla Application Suite can lead to users having the entire contents of their Program Files folder deleted. The problem is present in the 2004-02-03-18 and later trunk Windows installer and net installer builds. The affected binaries have had the suffix -dangerous added to their filenames and been removed from the latest-trunk and latest directories on the FTP site. Testers are strongly advised not to download these dangerous builds. The issue is being tracked in bug 233014 (please do not add unnecessary comments to this bug). Thanks to Zbigniew Braniecki for alerting us to this problem.

Update: The bug is now fixed and latest Windows installer and net installer builds do not exhibit the problem.

Perhaps the "delete all files" method of installation should only delete KNOWN directories from the base install directory and leave any others alone -- that is: bin, chrome, components, chrome, components, defaults, Plugins, res, searchplugins, uninstall.

Any non-directory files at the base install directory would be deleted, but directories not in the above list would be left alone. This would allow for complete uninstallation of plugins, etc. but keep any user-created directories.
