I think this is most known as toctou not tocttou

compare with google

http://download.oracle.com/javase/tutorial/essential/io/check.html mentions it as TOCTTOU --173.25.223.151 (talk) 02:55, 29 January 2011 (UTC)[reply]

linux

someone should mention that you can prevent tocttou under linux via the following sysctl settings: fs.protected_hardlinks = 1 and fs.protected_symlinks = 1 79.230.118.243 (talk) —Preceding undated comment added 14:14, 18 June 2013 (UTC)[reply]

Other examples and solutions

File systems aren't the only place TOCTOU shows up. Here are some other familiar examples that might be worth working into the article.

TOCTOU vs. TOCTTOU

We list the TOCTTOU acronym first, and use it preferentially. I think that's backwards. I tried some searches:

Engine TOCTOU TOCTTOU
Google 68,700 24,500
Google Scholar 719 603
Bing 30,000 13,600
ACM Digital Library 0 8
IEEE Explore Digital Library 10 2
Github 8 3

There's a clear preference for TOCTOU in actual usage in both the general purpose and technical corpora. I can only assume that the ACM outlier is due to a house style preference, which the IEEE doesn't share. Surprisingly, kernel.org's bugzilla comes up with "Zarro Boogs" for either term. Unclear what to make of that.

I think we should go with the most common usage.
