electron/docs/development/upgrading-crashpad.md

• Get the version of crashpad that we're going to use.

  • libcc/src/third_party/crashpad/README.chromium will have a line Revision: with a checksum.
  • clone Electron's Crashpad fork and create a new branch
  • git clone https://chromium.googlesource.com/crashpad/crashpad
  • git checkout 01110c0a3b
  • git remote add electron https://github.com/electron/crashpad
  • git checkout -b electron-crashpad-vA.B.C.D
    • A.B.C.D is the Chromium version found in libcc/VERSION and will be something like 62.0.3202.94

• Make a checklist of the Electron patches we need to apply e.g. git log --oneline or view http://github.com/electron/crashpad/commits/previous-branch-name

• Foreach patch:

  • (in new branch) git cherry-pick checksum
  • resolve any conflicts
  • make sure it builds
  • add && commit

• Push your work: git push electron electorn-crashpad-v62.0.3202.94

• Update Electron to build the new crashpad:

  • cd vendor/crashpad
  • git fetch
  • git checkout electron-crashpad-v62.0.3202.94

• Regenerate Ninja files

  • from Electron root's root, run script/update.py
  • script/build.py -c D --target=crashpad_client
  • script/build.py -c D --target=crashpad_handler
  • If both of these work, it's probably good.

• Push changes to submodule reference

  • (from electron root) git add vendor/crashpad
  • git push origin upgrade-to-chromium-62
