[classlib] New ICU release

ICU 3.8.1 has just been released, so Id like to propose that after M4 we 
upgrade to this release, add it to the fetch-depends target and remove 
the "homemade" ICU4J jar we have stored in SVN.

Im running the tests with the new version now to make sure there are no 
regressions and will be happy to make the required changes when the time 
comes.

Objections?

Regards,
Oliver

Hi, Oliver,

Moving to ICU3.8.1 still introduces 2% degradation on SPECjbb2005. We
might stick to current version for a while, I will have a look when I
have spare time.

Thanks,
Aleksey.

Re: [classlib] New ICU release

Posted by Aleksey Shipilev <al...@gmail.com>.
Wow, thanks Oliver. My head is spinning these days, I forgot about new
ICU library.

Ok, last time we have measured the performance without Tony's patch
onboard, so we might recheck migration to ICU 3.8.1 again. Since
Tony's patch delegates much more functionality to ICU, the performance
benefits/degradations should be more evident. Hopefully will check
tomorrow.

Thanks,
Aleksey.

Re: [classlib] New ICU release

Posted by Oliver Deakin <ol...@googlemail.com>.
Hi Aleksey (and anyone else interested!)

Do you have any further comments on these changes? With the recent 
discussion over Tony's work on removing duplicate locale data I was 
wondering if it would be ok to step up to this stable release if icu4j 
and deal with performance issues "in the wild"? It seems to me that 
while we stall upgrading to a release version of this library it's 
performance will never be closely examined, and as such will continue to 
put the upgrade on hold indefinitely.

I would suggest we move to icu4j 3.8.1 and begin to feed back 
performance queries to the ICU team. Are there objections?

Regards,
Oliver

Re: [classlib] New ICU release

Posted by Oliver Deakin <ol...@googlemail.com>.
Hi Aleksey,

Thanks for performance testing the changes. It's great that the Dacapo 
benchmark has not been affected by this change, but I agree that the 
small SPEC degradation is a concern. However, I would argue that we 
should still upgrade to the new version. At this point I value bug fixes 
and stability over performance, and IMHO moving to a proper release 
version of icu4j is preferable to using the current mid development 
cycle build we have in SVN, even if there is a slight degradation in one 
of the benchmarks.

I would personally suggest that we still move to the new version of 
icu4j after M4 and address the performance issues as an ongoing task 
with the ICU developers.

Regards,
Oliver

Re: [classlib] New ICU release

Posted by Aleksey Shipilev <al...@gmail.com>.
Hi, Oliver!

This change:
 a. does not affect composite Dacapo performance
 b. degrades SPECjbb2005 performance for 1-2%.

Taking (b) into the account, I would like to vote for deferring
immediate moving to ICU 3.8.1. We can revisit this one more time if
there's a way to beat the degradation.

Thanks,
Aleksey.

Re: [classlib] New ICU release

Posted by Oliver Deakin <ol...@googlemail.com>.
Thanks for offering to help Aleksey, that's great!

Ive opened HARMONY-5313 and attached a script and a patch to be applied. 
Please run the script before applying the patch, as one file needs to be 
moved before it is patched. Once it's applied, if you run the 
fetch-depends target you should see that the new ICU4J jars are 
downloaded. Then if you just rebuild you should be ready to run with the 
new version.

Thanks for the help!

Thanks, Oliver!

Performance data on microtests is looking good, however I wonder what
impact it has on DRLVM and large benchmarks. Haven't you filed JIRA
for this issue? If I'll have exact steps to build configuration with
new ICU, I could check it's performance before committing the changes
to the trunk.

Hi Oliver,

Do you have the same data for current charset encoder/decoders (at the
moment default harmony build not using ICU for charset
encoding/decoding)?

Thanks.

Re: [classlib] New ICU release

Thanks Aleksey.

I have run the JUnit tests with the IBM VME and they pass without any 
new failures. I have also run the encoding/decoding test in HARMONY-3709 
a number of times - in general, ICU4J 3.8.1 performs in that test as 
well or slightly better than the ICU4J 3.8 jar we are currently using. I 
have attached the results of the latest run I made [1].

Good news, Oliver!

Anyway, basing on our previous experiences with ICU changes, we might
first try how Harmony performs with new ICU onboard before making this
change default. That's not only JUnit and other validation suites, but
performance too (say, Dacapo and other benchmarks performance).

Thanks,
Aleksey.
