The infrastructure runs everything already in Python3, so this is
mostly a clean-up.
For MB, a python2 holdover was removed and new lint errors were
fixed.
The renames were automated with:
git grep -e "/usr/bin/python$" |
cut -d':' -f1 |
xargs
sed -i 's/#!\/usr\/bin\/python$/#!\/usr\/bin\/python3/1'
and
git grep -e "/usr/bin/env python$" |
cut -d':' -f1 |
xargs
sed -i 's/#!\/usr\/bin\/env python$/#!\/usr\/bin\/env python3/1'

- Removed duplication and unnecessary indirection from all suites testcfgs.
- Introduced a more comprehensive context to cover both command context and other platform specific concerns.
- Propagated above context to TestLoader to allow for test counting command execution on all platforms.
- Wrapped original pool with another class to give it a new interface and allow injecting different implementations in the future.
- Consolidated progress indicators under a single processor in the pipeline.
- Consolidated result retention requirements calculation outside of pipeline chain.
- Refactored LoaderProc and got it under tests.
- Added some more tests for the standard runner.
- Extracted BuildConfig class.

- removed some 'feature envy' instances:
- created a AugmentedOptions class to take care of non trivial option look-ups
- moved some calculation closer the the actual data
- promoted parameter that was passed around a lot (options) to filed in the offending class
- similar object creation looks a bit more similar
- CommandContext provides a wrapper that ensures resource de-allocation
- separate tests from standard and num_fuzz runners
- added a couple of more tests to improve coverage
This is still in flux. But further changes risk creating a disconnect between the original implementation and further refactorings.

NumFuzz passes various flags to V8 testing randomly, which can lead to
various flag contradictions with existing flags. Up to now the system
ignored the check for contradictions and kept running the test cases,
leading to false positives.
This change adds a new v8 flag --exit-on-contradictory-flags that
exists gracefully when a contradiction is detected. On the numfuzz
side we now filter simple contradictions beforehand.
Measurements showed that ~2% of all numfuzz tests ran into
contradictions. Around half of them are simple contradictions
(repetitions and inversions), which are now filtered beforehand.
The remaining ones (redundant or contradictory implications) are
now ignored.

This is a follow up CL for https://crrev.com/c/3538284.
Tests credited to https://crrev.com/c/3468352.
- Add unicode filename path test.
- Convert ansi encoded filename argv to utf8 encoded on windows. Because
the ansi encoded filename argv may lose some information for unicode
filename, and we need to use GetCommandLineW to get the actual unicode
filename argument. And we convert it to utf8 encoded to be consistent
with subsequent processing.
- Use REPLACEMENT CHARACTER to replace the characters which cannot be
encoded with sys.stdout.encoding in progress.py.
This CL should be **reverted** if new unicode filenames cause problems.

When --maglev is set, tier up to Maglev from unoptimized tiers based on
--interrupt-budget-for-maglev, initially set to 40KB (which should very
roughly by 1/10th of the time until the TF tierup decision is made).
On the first interrupt, a non-concurrent optimization to Maglev is
requested, which the next call to the marked function will perform.
- There is no support for tiering from Maglev to TF yet.
- Maglev's language support is minimal and tests are not expected to
pass with --maglev.
- Disable --maglev by default for now.
Drive-by: fixes related to Maglev flag definitions.

Now that we are able to compact map space, we can also get rid of the
map space and allocate maps in the old space instead. This CL introduces
a FLAG_map_space for enabling/disabling the map space but the map space
remains enabled by default for now.
Without a separate space for maps, the GC can't prevent relocation of
maps anymore. Therefore this CL always allows compaction of maps when
running without a map space. Rename flag to --compact-maps to better fit
this scenario.
mkgrokdump and debug_helper also need to be updated to look for maps
also in the old space. The map space is now optional.
