Request for review: 7123229: (coll) EnumMap.containsValue(null) returns true
by Neil Richards 31 Jan '12

31 Jan '12

Hi all, When proposing the change for 6312706 [1], I erroneously managed to convince myself (and others!) that it would be safe to use 'new Integer(0)' for java.util.EnumMap.NULL (the object used to mark null values for entries in the map) [2]. This was on the basis that I thought it was only compared by identity. However, on closer inspection, this turns out not to be the case. 7123229 was raised to report the bug that was introduced based on this invalid assumption. I've created a webrev with a suggested fix for 7123229 [3], which changes NULL to be an Object which: * will only return 'true' from equals(Object) for itself * returns 0 from hashCode() For good measure, it also returns a sensible value from toString(). Please review this fix and let me know your thoughts, Thanks, Neil [1] http://hg.openjdk.java.net/jdk7/tl/jdk/rev/c1e87a18e46a [2] http://mail.openjdk.java.net/pipermail/core-libs-dev/2011-March/006353.html [3] http://cr.openjdk.java.net/~ngmr/7123229/webrev.00/ -- Unless stated above: IBM email: neil_richards at uk.ibm.com IBM United Kingdom Limited - Registered in England and Wales with number 741598.

Review request: Fast multiplication and division
by Tim Buktu 30 Jan '12

30 Jan '12

Hi everyone, I made a patch against the latest BigInteger.java that speeds up multiplication and division of large numbers. It is based on Alan Eliasen's excellent work which unfortunately hasn't been included yet. There are three algorithms in this patch, 1) Karatsuba multiplication which is used above ~480 decimal digits; 2) Toom-Cook multiplication which is used above ~720 decimal digits; 3) Burnikel-Ziegler division which is used above ~480 decimal digits. Karatsuba and Toom-Cook were implemented by Alan, and Burnikel-Ziegler was implemented by me. I have reviewed Alan's code, and I verified that the patched BigInteger passes BigIntegerTest (using suitable lengths) as well as my own tests. On my machine, the speedup for multiplication is as follows: * 1.3 times faster for 1,000-digit numbers * 3.9 times faster for 10,000-digit numbers * 12.4 times faster for 100,000-digit numbers The speedup for division is as follows: * 1.4 times faster for 1,000-digit numbers * 3.4 times faster for 10,000-digit numbers * 10.4 times faster for 100,000-digit numbers The patch is at https://gist.github.com/1576016 and the patched BigInteger.java is at https://gist.github.com/1576025 . Thanks, Tim
