These instructions are for the Android external/wayland-protcools repository.
## Updating from upstream
### Update the freedesktop.org/ directory
1. Checkout the upstream sources to a working directory if you haven't
already with
`git clone git://anongit.freedesktop.org/wayland/wayland-protocols`,
or otherwise pull down the latest changes if you have a checkout.
2. Sync to the desired release tag (`git tag -l` to view them)
`git checkout $TAG`
3. The freedesktop.org/ directory here should be a simple copy of this
checkout. A tool such as `meld` can be used to view and apply the
differences.
`meld freedesktop.org/ /path/to/freedesktop.org/wayland-protocols/`
4. Note that we add NOTICE, MODULE_LICENSE_MIT and METADATA files as part of
our policies around open source code. Leave these alone unless there is
a reason to change them.
* NOTICE should duplicate COPYING from upstream.
* MODULE_LICENSE_MIT should match the source code license.
* METADATA should indicate the version of the upstream source used, and
should be updated to match.
### Update the chromium.org/ directory
1. Checkout Chromium sources if you haven't already with
`git clone https://chromium.googlesource.com/chromium/src.git`, or
otherwise pull down the latest changes. This is a large checkout
unfortunately, even though we only want a small subset of it.
2. Sync to the desired release tag, or just use master if you would like.
3. The chromium.org/ directory should ba a **PARTIAL** copy of
src/third_party/wayland-protocols from your checkout. In particular these
should match:
* chromium.org/unstable/ and src/third_party/wayland-protocols/unstable/
* chromium.org/LICENSE and src/third_party/wayland-protocols/LICENSE
* chromium.org/README.chromium and src/third_party/wayland-protocols/README.chromium
We **do not** need:
* src/third_party/wayland-protocols/include/ and
src/third_party/wayland-protocols/protocol both contain source code
generated from the protocol files, which is not needed here.
* src/third_party/wayland-protocols/src (if you have it) is itself a clone
of a version of the freedesktop.org upstream sources.
* src/third_party/wayland-protocols/OWNERS causes trouble with Android
Gerrit.
* src/third_party/wayland-protocols/BUILD.gn.
4. Note that we add NOTICE, MODULE_LICENSE_MIT and METADATA files as part of
our policies around open source code. Leave these alone unless there is
a reason to change them.
* NOTICE should duplicate LICENSE from upstream.
* MODULE_LICENSE_MIT should match the source code license.
* METADATA should indicate the version of the upstream source used, and
should be updated to match.
