      [modules] Add ResolveModuleCallback that takes import assertions · 9d72d08a
      Daniel Clark authored 
      This change completes the necessary API changes for import assertions
discussed in
https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY.

The old ResolveCallback is deprecated and replaced with a
ResolveModuleCallback that includes import assertions.  Until
ResolveCallback is removed, InstantiateModule and associated functions
are modified to accept both types of callback, using the new one if it
was supplied and the old one otherwise.  An alternative that I chose not
to go with would be to just duplicate InstantiateModule and associated
functions for both callback types.

SyntheticModule::PrepareInstantiate's callback parameter was unused so I
removed it.

      Revert "Enable simulating errors to test fuzzer reliability" · c0b46d97
      Michael Achenbach authored 
      This reverts commit 4ad08c82.

Reason for revert: Need to retry with bugs in separate stack
frames.

Original change's description:
> Enable simulating errors to test fuzzer reliability
>
> This adds a d8 flag --simulate-errors, which on shutdown will cause
> certain errors. This enables testing the reliability of sanitizers.
>
> This will cause a fatal error, a dcheck (if available) or a
> violation that can be detected with one of the following sanitizers:
> ASAN, UBSAN, MSAN, CFI.
>
> The same flag used in differential fuzzing will cause an error
> subsumed with the error state "fake_difference".

      We run tests in parallel which can cause multiple tests to write to
the shared v8.log file. This obviously breaks the simple assertions in
mjsunit/tools/log.js.

- Use temporary files for log testing with --logfile='+'

- Change the symbol from '&' to '+' for using temporary files for
  logging with --logfile

- Enable skipped log tests again.

      [test][d8] Add d8.log.getAndStop helper · 262fbcbe
      Camillo Bruni authored 
      The new helper function allows us to write tests for log parsing
without the need of first generating a log file.
This makes it easier guard against errors when the log format changes.

- add d8.log.getAndStop helper
- add basic log test
- fix test that regresses due to changed gc timing
