Idea from bug137818: > > - be able to disable API tests easily (87 relinking --> 9 relinking) > It is already possible with build-webkit --cmakeargs="-DENABLE_API_TESTS=OFF" > performance win: ~ 1 minute Now the incremental build takes 21 seconds with ld.gold if I touch only one random file from WebCore. It is still too much during active development. :) I know I can disable API tests with --cmakeargs="-DENABLE_API_TESTS=OFF" command line argument of build-webkit. It reduces build time to ... seconds. But it isn't as comfortable as it can be. This command line option has a big issue, it is passed to GCC as command line argument. If you change your mind, and you would like to build API tests again or vice-versa (or simple forget to pass this option), all sources will be rebuilt. :-/ I checked the code base and it seems only GTK needs this define to be passed to compiler for 2 files only: - Source/WebKit2/UIProcess/gtk/InputMethodFilter.cpp - Source/WebKit2/UIProcess/API/gtk/WebKitWebViewBase.cpp ( which includes InputMethodFilter.h ) My goals are: - simpler option than --cmakeargs="-DENABLE_API_TESTS=OFF" , or environment variable - avoid rebuilding everything if ENABLE_API_TESTS configuration changes How to do it: still thinking :)
Let's see the numbers. (I missed to add them to the description) Incremental build time after touching a cpp from WebCore: - wihtout gold linker: 87 seconds --> 19 seconds (with / without API) - with gold linker: 21 seconds --> 9 seconds (with / without API)
