Created attachment 146621 [details] test project In the attachecd project, "generated.h" file is regenerated during build (removed on clean, then generated again before build). This causes parsing of most files in the project - although regenerated header content is the same. This is incorrect.
Investigation shows that events processing is rather complicated. For now it is as follows: *** Event sources (classes that fire events) are four: - CndIndexer (1 instance) - NativeProjectListener (an instance per project) - FileChangeListener (1 instance) - NativeProjectRegistry (1 instance) *** Events, threads and Request Processors (RPs) Code model owns a single static 1-thread RP called Model RP ** NativeProjectRegistry (1 global instance) - closes projects in the same thread it's caled (MakeProject.RP - 1-thread RP per project) - opens projects in its own static 1-thread RP ** CndIndexer (1 global instance) Calls ProjectBase.checkForRemoved in Model RP ProjectBase.onFileImplExternalChange in Model RP ProjectBase.onFileObjectExternalCreate in Model RP ** SuspendableFileChangeListener (1 global instance) Wraps ExternalUpdateListener, folds remove-create events, calls ExternalUpdateListener in its own 1-thread RP ** ExternalUpdateListener (1 global instance) Also folds remove-create events Calls ProjectBase.checkForRemoved in Model RP ProjectBase.onFileImplExternalChange in Model RP ProjectBase.onFileObjectExternalCreate in Model RP ** NativeProjectListenerImpl (instance per project) Calls RepositoryUtils.onProjectDeleted in RequestProcessor.getDefault() ProjectBase.onFileItemsAdded in Model RP ProjectBase.onFileItemsRemoved in Model RP ProjectBase.onFileItemRenamed in Model RP ProjectBase.onFileItemsPropertyChanged in Model RP
