Description Dave Malcolm 2005-06-21 21:41:53 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050512 Red Hat/1.0.4-1.4.1 Firefox/1.0.4

Description of problem:

Version-Release number of selected component (if applicable):

How reproducible:
Couldn't Reproduce

Steps to Reproduce:
1. Create a Standard Make C project, set the project contents to be a non-standard directory outside the workspace (one of my source trees from an untarred source tarball of ximian-connector-2.0.2, as it happens, mounted on a local filesystem, not NFS)
2. Try to browse the project in the C/C++ Projects tab by expanding one of the tree nodes

Actual Results:  Eclipse becomes unresponsive for a long time, and eventually shows the expanded form of the node; CPU usage is close to 100%

Looking in top, the top process is "java".  Doing an strace -p on the PID, it appears that every file in that level of the project is being opened and the first roughly 30 bytes of each file is being read, one byte at a time.  (perhaps  doing MIME sniffing)

Problem appears to be one-time only; I could reproduce it.

Expected Results:  Should be able to expand tree nodes in the project instantaneously

Additional info:


Doesn't seem to be so bad on a upstream Eclipse running on the Sun JDK

"Problem appears to be one-time only; I could reproduce it." should have read
"roblem appears to be one-time only; I couldn't reproduce it."
