Re: [分享] Linux v3.0... 再等等
※ 引述《Spig (Spig)》之銘言：
From Linus' google+ message two hours ago,
Linus Torvalds
Why do we always find the subtle bugs just before a release?
Looks like I won't be releasing 3.0 today, just because Hugh found this
incredibly subtle pathname lookup bug. We have a patch, we understand the
problem, and it looks ObviouslyCorrect(tm), but I don't think I want to
release 3.0 just a couple of hours after applying it.
我今天大概不會發布 3.0 了，因為 Hugh 發現了路徑搜尋的小細節出了差錯。
我們有修正檔，也確認了問題，而且看起來明顯是正確的(註), 但我大概不會在
修正這個問題後幾小時內就發布 3.0。
Of course, the bug is so hard to see that Hugh needs weeks to reproduce it
even with his stress test, so we could just ignore it and backport the fix
later. But I really hate making releases with known issues even if it's
almost certainly a "nobody will ever hit this in practice" issue.
當然，這個問題實在太難發現了，即使在 Hugh 的壓力測試下他還是需要花好幾個禮拜
才能重現它，所以我們其實可以就忽略它然後事後再回溯修正這個問題。不過我還是痛恨
發布一個有已知問題的版本，就算幾乎可以確定沒有人實際上會真的遇到這個狀況。
Oh well.
註: ObviouslyCorrect, 意指修正檔(patch)明顯可以有效修正問題，可以馬上加入核心
