Aaron Knobloch 1445166166 [fuchsia] Guard against empty manifest.json in update_sdk.py
In some infra builds, we have observed an empty manifest.json file. This is unexpected, and it's unclear where the empty file stems from. It's potentially a problem during checkout, but could also be incorrect cleanup in between infrastructure runs.

Regardless, we can guard against the condition and gracefully recover when this happens. This will cause a wipe of the SDK directory and refetch, which is the correct way to recover from an unknown SDK checkout state.

About

//build contains:

  • Core GN templates and configuration
  • Core Python build scripts

Since this directory is DEPS'ed in by some other repositories (webrtc, pdfium, v8, etc), it should be kept as self-contained as possible by not referring to files outside of it. Some exceptions exist (//testing, select //third_party subdirectories), but new dependencies tend to break these other projects, and so should be avoided.

Changes to //build should be landed in the Chromium repo. They will then be replicated to the stand-alone build repo by the gsubtreed tool. Note: You can find all directories already available through gsubtreed in the list of all chromium repos.

Contents

  • //build/config - Common templates via .gni files.
  • //build/toolchain - GN toolchain definitions.
  • Other .py files - Some are used by GN/Ninja. Some by gclient hooks, some are just random utilities.

Files referenced by //.gn:

  • //build/BUILDCONFIG.gn - Included by all BUILD.gn files.
  • //build/secondary - An overlay for BUILD.gn files. Enables adding BUILD.gn to directories that live in sub-repositories.
  • //build_overrides - Refer to //build_overrides/README.md.
