Package: offlineimap Version: 6.2.0.2 Severity: critical Justification: causes serious data loss
offlineimap calls critical code paths only via assert. If PYTHONOPTIMIZE is set, python will - besides other optimisations - ignore all assert statements. In combination, this caused my entire "sent" folder to get lost as I tried to sync it with a courier-imap server (on which the folder had just been created). I had reported a similar issue in 2008 (Bug #80: improper use of assert statement), though at that time it just duplicated mails instead of loosing them. (Python) upstream considers assert a mere debugging tool. See e.g. "Language Reference" section 6.3, first paragraph: > Assert statements are a convenient way to insert debugging assertions into a > program: The same section also explains that enabling optimization will cause assert statements not to be evaluated. Thus this is definitely a bug in offlineimap. assert should not be used to invoke regular code paths. -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.31.6-xo1.5-2-00377-g7f5e423 (PREEMPT) Locale: LANG=en_US, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages offlineimap depends on: ii python 2.6.5-5 An interactive high-level object-o ii python-support 1.0.8 automated rebuilding support for P offlineimap recommends no packages.
