Review Request : 7041612 : Rename StandardCharset to StandardCharsets
by Mike Duigou 04 May '11

04 May '11

Hello All; Per the most recent message from Mark Reinhold (http://mail.openjdk.java.net/pipermail/core-libs-dev/2011-May/006827.html) the recently added StandardCharset class will be renamed to StandardCharsets to better reflect that it is not an enum. We would like to get this change in ASAP. Webrev here: http://cr.openjdk.java.net/~mduigou/7041612/0/webrev/ Thanks, Mike

Codereview request: CR 7040220 java/char_encodin Optimize UTF-8 charset for String.getBytes()/toCharArray()
by Xueming Shen 02 May '11

02 May '11

Hi This is motivated by Neil's request to optimize common-case UTF8 path for native ZipFile.getEntry calls [1]. As I said in my replying email [2] I believe a better approach might be to "patch" UTF8 charset directly to implement sun.nio.cs.ArrayDecoder/Encoder interface to speed up the coding operation for array based encoding/decoding under certain circumstance, as we did for all single byte charsets in #6636323 [3]. I have a old blog [4] that has some data for this optimization. The original plan was to do the same thing for our new UTF8 [5] as well in JDK7, but then (excuse, excuse) I was just too busy to come back to this topic till 2 days ago. After two days of small tweaking here and there and testing those possible corner cases I can think of, I'm happy with the result and think it might be worth sending it out for a codereview for JDK7, knowing we only have couple days left. The webrev is at http://cr.openjdk.java.net/~sherman/7040220/webrev Those tests are supposed to make sure the coding result from the new paths for String.getBytes()/ toCharArray() matches the result from the existing implementation. The performance results of running StrCodingBenchmarkUTF8 (included in webrev) on my linux box in -client and -server mode respectively are included at http://cr.openjdk.java.net/~sherman/7040220/client http://cr.openjdk.java.net/~sherman/7040220/server The microbenchmark measures 1-byte, 2-byte, 3-byte and 4 bytes utf8 bits separately with different length of data (from 12 bytes to thousands) Thanks! -Sherman [1] http://mail.openjdk.java.net/pipermail/core-libs-dev/2011-April/006710.html [2] http://mail.openjdk.java.net/pipermail/core-libs-dev/2011-April/006726.html [3] http://cr.openjdk.java.net/~sherman/6636323_6636319/webrev [4] http://blogs.sun.com/xuemingshen/entry/faster_new_string_bytes_cs [5] http://blogs.sun.com/xuemingshen/entry/the_big_overhaul_of_java
