XML schema saving is slow [message #119641]

Hi,

I have problems with newest M5 WTP version on linux machine (all
dependencies are downloaded and installed correctly, I don't use any other
plugins concurrently with WTP). When I try to modify and save XML schema,
sometimes it takes even few minutes, no matter how big schema is. Eclipse
just hangs in that moment.

I checked logs in my workspace but I don't see anything suspicious. Do you
know any possibilities to see what is exactly done in background? I'm
looking for something like decreasing log level ...

cheers

Michal

Hi Michal,

Did you uncheck the Disable caching preference in the
Preferences -> Internet -> Cache.

By default validation is performed against schemas on the net.
One schema pulling another one and some sites being slow to answer, this
can indeed be an excruciating experience. However once cache is enabled,
validation is immediate.

Yes, I have caching enabled, hovewer I'm working in wired environment
where Eclipse doesn't have direct internet access so it cannot download
anything from internet. Anyway - I don't include any other schemas which
are located in the network. I use only those ones defined by default in
XML catalog which are placed in jar files or other eclipse resources.

I used also tcpdump to check if eclipse is trying to connect somewhere
while saving schema, but no packets were sent.

It happenned to me as well.

I reported that in another post :

http://www.eclipse.org/newsportal/article.php?id=5477&gr oup=eclipse.webtools#5477

I had configured my proxy in the internet preferences but XSD saving was
generating many stalled jobs.

To make a long story short, I came to the conclusion that the proxy was
not taken into account and eventually put the blame on the JVM.
Switching from 1.4.2_06 to 1.4.2_08 solved (but I probably had overtweaked
my 1.4.2_06 as well ;-).

Using WTP from home (no proxy) everything was fine.

Hope this helps. As a last resort, you can disable validation in builders
either at the workbench level or at the project level.

Hi,

as I said I don't use any type of internet connection (and as I see,
Eclipse doesn't trying to send any packets into the network). I use
jdk1.5_04, I think most useful information for me would be how to enable
some more debugging and tracing in Eclipse.

OK, no prob.
Sorry if some of the things detailed below are already familiar to you.

Package Explorer -> Import -> External Plugin and Fragments

For a start I would select :

* org.apache.xerces
* org.eclipse.wst.common.uriresolver
* org.eclipse.wst.internet.cache
* org.eclipse.wst.internet.proxy
* org.eclipse.wst.validation
* org.eclipse.wst.validation.ui
* org.eclipse.wst.xml.core

Pull the source code out as well (radio button group : Import as, Proj
with source).

Then create a new run config with "Debug as...",

Select the Eclipse Application category. Press "New".
Accept defaults.

This will generate a runtime workbench.
In this workbench, manipulate your schema, when things start to get slow,
switch to the debug perspective in the home workbench,
find the working thread and prese the pause button.

That's a good start for investigating...

Anything else please ask.

I'd also encourage you to open bugs for these issues and feel free to add
patches to fix the problem, or any analysis of the problem to the bugzilla
bug.
