bootstrap: handle snapshot errors gracefully #43531

joyeecheung · 2022-06-22T13:26:00Z

This patch refactors the SnapshotBuilder::Generate() routines
so that when running into errors during the snapshot building
process, they can exit gracefully by printing the error
and return a non-zero exit code. If the error is likely to
be caused by internal scripts, the return code would be 12,
if the error is caused by user scripts the return code would
be 1. In addition this refactors the generation of embedded
snapshots and directly writes to the output file stream
instead of producing an intermediate string with string
streams.

The first commit is from https://chromium-review.googlesource.com/c/v8/v8/+/3716682.

If the error is likely to be caused by internal scripts, the return code would be 12

Did you choose 12 arbitrarily or is there any special significance behind it?

Labeling with "blocked" so that it won't be landed unexpectedly before the v8 patch is backported.

Original commit message: [serializer] allow SnapshotCreator to destruct without a blob Previously SnapshotCreator demanded a blob to be created before it can be destructed in debug build, this patch removes the DCHECK so that the embedder can choose not to create the blob when e.g. the snapshot building isn't successful due to errors.
