CEF development has faced delays in the past due to the time lapse between
|
||
|
|
submitting patches to the Chromium and WebKit projects and having those patches
|
||
|
|
accepted. A CEF developer will hopefully earn Chromium commit access at some
|
||
|
|
point which should partly mitigate this problem but will not eliminate it
|
||
|
|
completely. There may still be instances where CEF requires changes to the
|
||
|
|
Chromium/WebKit code base that are not desired by the Chromium/WebKit projects
|
||
|
|
as a whole. To address this situation in the near term and with a minimum of
|
||
|
|
maintenance headaches (i.e. without forking) this project adds a patch
|
||
|
|
capability as part of the CEF build process. The patch capability works as
|
||
|
|
follows:
|
||
|
|
|
||
|
|
1. The CEF developer creates one or more patch files containing all required
|
||
|
|
changes to the Chromium/WebKit code base and places those patch files in the
|
||
|
|
"patches" subdirectory.
|
||
|
|
2. The CEF developer adds an entry for each patch file in the "patch.cfg" file.
|
||
|
|
3. The CEF "patch" project, which is a build dependency for the "webkit\config"
|
||
|
|
project, applies the patches to the Chromium/WebKit source tree using the
|
||
|
|
patcher.py tool in the tools directory. If necessary the patcher.py tool
|
||
|
|
also rewrites the "patch_state.h" file which defines the CEF_PATCHES_APPLIED
|
||
|
|
preprocessor value.
|
||
|
|
|
||
|
|
To disable automatic application of patches to the Chromium/WebKit code base
|
||
|
|
create an empty "NOPATCH" file in the "patch" directory. Sections of the CEF
|
||
|
|
code base that otherwise require patches will be disabled using the
|
||
|
|
CEF_PATCHES_APPLIED preprocessor value defined in the "patch_state.h" file. Be
|
||
|
|
warned that not applying all required patches may break important CEF
|
||
|
|
functionality.
