Description christophe.paris CLA 2011-02-02 12:16:37 EST 
Build Identifier: 20100917-0705

When a file with a very long lines exists in you project and is included in your search results, the results tree is broken. The tree is build with white label and a huge horizontal scroll bar is displayed.
Any other search is broken after that, the only way to fix it is to restart eclipse.

Reproducible: Always

Steps to Reproduce:
1. Create a file with a very long line in your project (more than 6000 characters)
   eg: for i in $(seq 1 800) ; do echo -n "hello$i" >> hello.txt ; done
2. In the menu choose : "Search>File"
3. Search for some text included in the file just created (eg: hello)

Most likely an SWT issue or OS limitation.

Note, the corruption only appears to occur when you expand the search element which contains the long line, see attached screen shots. 

Hopefully this will help in tracking down this problem. On average, this problem causes me to have to restart Helios 2 to 3 times per day, which is rather annoying.
Comment 5 Felipe Heidrich CLA 2011-05-18 09:50:03 EDT 
This is an OS limitation.
Comment 6 Mark Booth CLA 2011-05-18 10:55:36 EDT 
Does that mean this can't be fixed, won't be fixed, or that we need to report this as a bug elsewhere? If so, where?
Comment 7 Timo A. Hummel CLA 2011-08-23 04:39:10 EDT 
Even if it is an OS limitation, which I doubt, a workaround should be easy: Don't put the whole line length into the tree.

Instead of writing megabytes of data in the search results, strip the search results to a specific length (probably append something like [long line has been stripped].

Also, trying to open a file with a very long line also causes eclipse to hang. No matter if this is an OS issue or not, this needs to be adressed in whatever way. Hangs are a no-go in any case!
