slow and 100% cpu [message #16894] Mon, 15 October 2007 15:30 Go to next message

I have a ruby project with more than 70 integrated files (one script
requiring another script requiring another, etc). When I make a small
change in the editor the cpu spikes to 100% and it takes several seconds
to recover. I really like the Ruby extension and so I'm really bummed
to report that this makes the extension unusable for me. I could not
find a bug report on this or anything on the mailing list. I thought
I'd post here before thinking of a bug report.

Eclipse 3.3 on Linux, with DLTK 9.0 and 9.1. I believe I tried this
with the native ruby and with JRuby with similar performance.

Any ideas?

Thanks,
Geoff

Hi Geoff,

We also found such problem for big tcl projects.

We are working on it.
For now I've made some changes in 1.0 version, which improve performance.
I will send message then new version with fixes will be available for
download. I suppose it will be today.

Thanks, Andrei.

Hi Geoff,

We provided new build of DLTK 1.0. You could obtain it from Eclipse DLTK
Download area at Eclipse. Direct
link( http://download.eclipse.org/technology/dltk/downloads/drops/ R1.0/I-I200710161345-200710161345/)

Please could you test it on your project, it should help with
performance problems.

Thanks, Andrei.

Would these fixes be available from an eclipse update site?

For instance, I saw integration builds at:
http://download.eclipse.org/technology/dltk/updates-dev/0.9/

I have already downloaded the package from the link you sent. I was
getting ready to install it when I came across that info.

Thanks,
Geoff

Uninstalled previous versions, and then unzipped the all in one bundle.

Eclipse did not work right and the Manage Configuration showed no
entries. The Find and install didn't show my entries either. I had to
revert to the backup I had made.

Not sure if I should have done something different or not. I figured
that was how I should install the Integration zip, but no love...

I was able to install the binaries by unzipping them into the
appropriate eclipse folders, however, I wasn't able to install the
SDK's because of dependencies problems.

These are some of the dependencies problems I had with this SDK, it
appears this zip file only included the older files from a previous build.

Hi Geoff,

I suppose problems are because we made some significant changes in 1.0
version in indexing.

We are thinking about correct update procedure, but not ready with it yet.

To solver problem please try following steps:

1) Remove all 0.9 components from features and plugins subfolder of
Eclipse.( But this is not necessary, becase Eclipse should use plugins
and features with greater version numbers ).

2) Remove all org.eclipse.dltk.* folders from your workspace .metadata
subfolder.
3) Install new 1.0 version of dltk.
4) Start Eclipse with -clean command line option.
5) After eclispe started, please call Build -> Clean for all projects.

I suppose this should help.

Thanks, Andrei.
