Interesting

  • There is some strangeness with Rails’ handing of invalid dates outside of the range for a Time object. For example, February 31, 1900. This involves Rails turning it into a Time object, and then back into a Date.

  • Multiple have found an interesting edge case bug in MySql which results in inconsistent ordering. It has been repeated in versions 5.1a and 5.1b, but we didn’t navigate the MySql bug system yet to find/report it. Here are the query conditions to reproduce it, which could be common in test scenarios for some projects:

* LIMIT <= 5
* ORDER BY id DESC
* > 5 rows in table
* Where clause has index (not compound with id)
