# Upgrading Dart's SDK for HTML (blink IDLs).
#
# Typically this is done using the Dart WebCore branch (as it has to be
# staged to get most things working).
#
# Enlist in third_party/WebCore:
# > cd src/dart/third_party
# > rm -rf WebCore (NOTE: Normally detached head using gclient sync)
# > git clone https://github.com/dart-lang/webcore.git WebCore
#
# To update all *.idl, *.py, LICENSE files, and IDLExtendedAttributes.txt:
# > cd sdk
# > python3 tools/dom/scripts/idlsync.py
#
# Display blink files to delete, copy, update, and collisions to review:
# > python3 tools/dom/scripts/idlsync.py --check
#
# Bring over all blink files to dart/third_party/WebCore (*.py, *.idl, and
# IDLExtendedAttributes.txt):
# > python3 tools/dom/scripts/idlsync.py
#
# Update the DEPS file SHA for "WebCore_rev" with the committed changes of files
# in WebCore e.g., "WebCore_rev": "@NNNNNNNNNNNNNNNNNNNNNNNNN"
#
# Generate the sdk/*.dart files from the new IDLs and PYTHON IDL parsing code
# copied to in dart/third_party/WebCore from src/third_party/WebKit (blink).
#
# > cd src/dart/tools/dom/script
# > ./go.sh
#
# Finally, commit the files in dart/third_party/WebCore.
