Description Bertrand HUGUIES CLA 2010-09-23 10:25:19 EDT 
Build Identifier: Eclipse IDE for C/C++ Developers  Build id: 20090619-0625

Every time I build, even if I use a Make Target in a single folder, the make command runs quickly but the "Build Process..." is blocked on "Updating project..." forever.

All binary parsers and indexer can be turned off, it is the same behavior.

Searching for this problem, I found this :
http://dev.eclipse.org/newslists/news.eclipse.tools.cdt/msg09874.html
that explains that Eclipse is going through a long process of refreshing the entire project tree every time a build process is launched.
On big projects, it never ends.

Reproducible: Always

Steps to Reproduce:
1. Open a CDT project with a large amount of folders and files (e.g. my project has 150.000 files and 10.000 folders)
2. Create a Make Target on source folder
3. Launch this Make Target

A bug fix for this problem would be to integrate the source code modification explained here :
http://dev.eclipse.org/newslists/news.eclipse.tools.cdt/msg09874.html

and adding a flag in the project properties the allows the user either to update project after each build or not.
