Bug#414838: aptitude can send terminal data to the printer at startup

I've finally gotten a chance to look into this again, and I may have a meaningful clue as to what's happening. I ran an strace, and although I can't reproduce the race on this single-CPU laptop, I *did* catch a background thread writing to stdout! It's the input thread, which does nothing but

Bug#414838: aptitude can send terminal data to the printer at startup

Thomas, I've gone over an strace provided by Vincent, and it looks pretty clear that all the write() system calls are from a single thread -- and the writes that overlap each other on stdout are actually just two writes, being called in sequence. The fact that they end up interleaved seems li

Hi, Well, I can't reproduce this, and I don't see many obvious places in the code that would be causing it. I tried adding some serialization to make the drawing code explicitly safe (previously it relied on being called only from the main thread; all the call sites I could find *should* be e

Package: aptitude Version: 0.4.4-3 Severity: grave Tags: security Justification: user security hole At startup, aptitude sends random characters to the terminal, including escape sequences. Some of them have the effect to send terminal data to the printer (this is not always reproducible), which c
