Reland "Make ANGLE program version only dependent on data that matters" This is a reland of commit 61728827d2e5ecce685578bc54bb2c744b65fc9a Changes made on top of previous commit 1. In src/program_serialize_data_version.py, fix the script error on Windows: anglebug.com/7918. 2. In BUILD.gn, replace the 'write_file' with 'response_file_content'. See https://gn.googlesource.com/gn/+/main/docs/reference.md#var_response_file_contents 3. In scripts/generate_android.bp.py, add code to handle the special GN build flag {{response_file_name}}. The code writes the list defined in srcs (identified by $(in) in Android blueprint) into a temp file named 'gn_response_file', and replaces the {{response_file_name}} with 'gn_response_file'. Original change's description > Changes made on top of original commit > 1. Enable execution permission on python script > program_serialize_data_version.py > 2. Remove unused list in libGLESv2.gni > 3. In angle/BUILD.gn, change file path from > "relative to angle_root", to "relative to root_build_dir", > so that inside the script program_serialize_data_version.py, > we don't have to find the absolute path of the code files for > hashing. > Original change's description > > This change introduces a new variable ANGLE_PROGRAM_VERSION > > to track the version of ANGLE source files that affect shader > > program serialization/deserialization. This change include more > > source files than necessary, to serve the purpose of a conservative > > jumping off point. We will narrow down the list of files for > > ANGLE_PROGRAM_VERSION hash generation in the future. > > Add a new script program_serialize_data_version.py that will > > be triggered during the build when the related source files changed. > > The script will generate a hash and the hash size from the related > > source files. In program serialization/deserialization and cache > > key generation, we will use this hash value instead of the entire > > ANGLE git hash. When the hash value changed, we know that the > > related source files changed, and we should invalidate the program > > cache and re-generate the blob cache / program binary. > > Bug: angleproject:4981 > > Change-Id: I2fb609416738d459d3289190c232c2d797ba58e3 > > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/4072215 > > Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> > > Reviewed-by: Cody Northrop <cnorthrop@google.com> > > Reviewed-by: Jamie Madill <jmadill@chromium.org> > > Commit-Queue: Yuxin Hu <yuxinhu@google.com> > Bug: angleproject:4981 > Change-Id: Iaa9eb0ab33439197bc30d03064fc245ea7ef1ea8 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/4113445 > Reviewed-by: Amirali Abdolrashidi <abdolrashidi@google.com> > Reviewed-by: Cody Northrop <cnorthrop@google.com> > Commit-Queue: Yuxin Hu <yuxinhu@google.com> Bug: angleproject:4981 Change-Id: Ib5bba199be6d08a1e19807026df0e7b747dbc8a9 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/4144078 Reviewed-by: Roman Lavrov <romanl@google.com> Commit-Queue: Yuxin Hu <yuxinhu@google.com> Reviewed-by: Cody Northrop <cnorthrop@google.com>
