memory leak in xBplusTreeBytes on late commit

altair — Mon, 11 Apr 2011 15:06:48 -0000

I'm using xBplusTreeBytes. Everything works fine if I make a commit after every insertion. For performance reasons I make a commit after 100 insertions. But then I have a memory leak. Can you tell me why the xBplusTreeBytes shows this behaviour?

bplusTest throws exception in v1.01

Sat, 11 Sep 2010 20:37:05 -0000

I imported and converted the project in C# (Visual Studio 2010). The conversion went well and the project builds fine. Once I run the test program, I get the following exception: "when walking found aa when expecting ab". The exception occurs on line 831 in the module bplusTest.cs.

I don't dare use the project until such a time that it runs cleanly in Visual Studio 2010/.NET 4.0.

Key Problem in hBplusTree in Java

I ran into a problem with the implementation of
"PrefixForByteCount" in hBplusTree. To reproduce this,
the particular string that initially caused the problem
was "cćser". The problem seems to be that the hash
method creates a string whose character length is
maxbytecount rather than a string whose utf-8 byte
length is maxbytecount. I can guess at why this is
happening - the ć is reported as one character in Java
but represented by two bytes in UTF-8.

The "PrefixForByteCount" in xBplusTreeBytes seems to be
implemented in the correct way. So as a quick fix for
myself, I added a similar loop to the end of
hBplusTree.PrefixForByteCount that trims the byte array
until it produces a string with the correct UTF-8 length.
