### Exporting node's patches to v8
|
||
|
|
|
||
|
|
```
|
||
|
|
$ cd third_party/electron_node
|
||
|
|
$ CURRENT_NODE_VERSION=vX.Y.Z # e.g. v10.11.0
|
||
|
|
|
||
|
|
# Find the last commit with the message "deps: update V8 to <some version>"
|
||
|
|
# This commit corresponds to node resetting V8 to its pristine upstream
|
||
|
|
# state at the stated version.
|
||
|
|
$ LAST_V8_UPDATE="$(git log --grep='^deps: update V8' --format='%H' -1 deps/v8)"
|
||
|
|
|
||
|
|
# This creates a patch file containing all changes in deps/v8 from
|
||
|
|
# $LAST_V8_UPDATE up to the current node version, formatted in a way that
|
||
|
|
# it will apply cleanly to the V8 repository (i.e. with `deps/v8`
|
||
|
|
# stripped off the path and excluding the v8/gypfiles directory, which
|
||
|
|
# isn't present in V8.
|
||
|
|
$ git format-patch \
|
||
|
|
--relative=deps/v8 \
|
||
|
|
$LAST_V8_UPDATE..$CURRENT_NODE_VERSION \
|
||
|
|
deps/v8 \
|
||
|
|
':(exclude)deps/v8/gypfiles' \
|
||
|
|
--stdout
|
||
|
|
```
|
||
|
|
|
||
|
|
When upgrading to a new version of node, make sure to match node's patches to
|
||
|
|
v8 by removing all the `deps_*` patches and re-exporting node's v8 patches
|
||
|
|
using the process above.
