Created attachment 157487 [details] logfile First, if multiple C++ projects are open and I change the toolchain on one of them, all projects are parsed. This takes a long time to parse other projects for no good reason. Second, if I change toolchain on multiple open projects at the same time, it causes problems and all sorts of exceptions and warnings can happen. It may also cause open files in a project fail to resolve identifiers. It may take 2 reparses to resolve them, or they won't resolve at all without restarting NetBeans. Product Version: NetBeans IDE Dev (Build 201511240002) Java: 1.8.0_66; Java HotSpot(TM) 64-Bit Server VM 25.66-b17 Runtime: Java(TM) SE Runtime Environment 1.8.0_66-b17 System: Windows 7 version 6.1 running on amd64; UTF-8; en_US (nb)
A lot of exceptions in log.
I can easily reproduce reparsing all projects when tool chain is changed for only one of them. The stack that forgets, which project is changed is: "Configurations events" at org.netbeans.modules.cnd.modelimpl.platform.CsmEventDispatcher$ItemListener.filesPropertiesChanged(CsmEventDispatcher.java:451) at org.netbeans.modules.cnd.makeproject.NativeProjectProvider.fireFilesPropertiesChanged(NativeProjectProvider.java:343) at org.netbeans.modules.cnd.makeproject.NativeProjectProvider.checkConfigurationChangedWorker(NativeProjectProvider.java:467) at org.netbeans.modules.cnd.makeproject.NativeProjectProvider.checkConfigurationChanged(NativeProjectProvider.java:414) at org.netbeans.modules.cnd.makeproject.NativeProjectProvider.propertyChange(NativeProjectProvider.java:590) at java.beans.PropertyChangeSupport.fire(PropertyChangeSupport.java:335) ... This seems to be a regression caused by hg.netbeans.org/cnd-main/rev/b45362ca9870
Pushed to enum: 5e7927b7bc9c 2e6b7f219fb3
Additional fix on enum 686abd77101a Some files from other open projects can still be parsed when you change tool chain. This happens because of our "parse once" optimization and the fact that compilation units that were supposed the "best context" for a particular header can change.
