Description Nick Boldt

2007-05-22 12:36:03 EDT

This might be a new bug but it might be related to 187396. Apologies if it's a dupe.

Trying to verify RC1 for bug 187410, I now get this when trying to 'search for new features...'

Steps:

1. Start Eclipse 3.3RC1 SDK.
2. 'Search for new features' using the Europa Discovery Site

!MESSAGE Digest could not be parsed:The entity name must immediately follow the '&' in the entity reference.

3. If I then expand the twisty next to Models and Model Development, Eclipse freezes for a very long time (at least a few minutes). Smaller categories eventually resolve (Other Tools, Charting and Reporting) but also hang for a surprisingly long time.

Can anyone else reproduce this, or should I just reboot? ;-)

The message implies that digest contains invalid characters (probably a name or description that contains '&' and is not escaped).

Agreed. I considered opening this against Community > Cross-Project but no one really works those so I thought I'd dump it here. ;-) CC'ing Bjorn.

Re: 2
With a little investigation (i.e., I opened the digest.xml inside the digest.zip and used IE as an XP parser) I discovered that the error is from the DSDP-DD project. Specifically, the feature:

<feature label="IPExact Editor & Checker" provider-name="Eclipse.org" id="org.eclipse.dd.ipxact" version="0.2.0.v20070521" > 

Notice the "&" instead of "&amp;" or better yet "and".

I meant to say "as an XML parser".

Yes, I can confirm this - it takes a long time although it eventually expands.
If the DSDP-DD guys will fix their feature files, I will respin the Europa RC0 build in order to fix the digest.xml

Fixed. 
1) s/\&/and/ 
2) bumped DSDP-DD versions from 0521 to 0522

Thanks, Bjorn. FWIW, I also got a long response time when doing the same thing with this Update site: http://download.eclipse.org/modeling/emf/updates/site-eclipsecon.xml

Not as long, but again, slower than expected. This time I was using Windows XP Pro, not my usual Linux desktop.

This appears to be fixed in RC1. Should we close this or wait to see if it breaks again? ;-)

Running on vista and before on xp, i always get the following error in the log : Digest could not be parsed:Element type "includes" must be followed by either attribute specifications, ">" or "/>". 
I have setup eclipse to check for updates on startup, and that is when the error is generated.

I tried this on XP using the current Europa update site and I did not receive any errors in the Error Log. If you are still seeing this bug, please provide more details including the base Platform version (are you still running 3.3RC1?) and the mirrors you are using to download from.
