Summary:
Previously we couldn't run env_basic_test on Env::Default (PosixEnv on
our platforms) since GetChildren*() behavior was inconsistent with our other
Envs. We can normalize the output of GetChildren*() such that these test cases
work on PosixEnv too.

Summary:
This diff makes the following improvement in regression_test.sh:
1. Add NUM_OPS and DELETE_TEST_PATH to regression_test.sh:
* NUM_OPS: The number of operations that will be issued
in EACH thread.
Default: $NUM_KEYS / $NUM_THREADS
* DELETE_TEST_PATH: If true, then the test directory
will be deleted after the script ends.
Default: 0
2. Add more information in SUMMARY.csv
3. Fix a bug in regression_test.sh where each thread in fillseq will all issue $NUM_KEYS writes.
4. Add --deletes in db_bench, which allows us to control the number of deletes instead of must using FLAGS_num.
Test Plan: run regression test with and without DELETE_TEST_PATH and NUM_OPS

Summary:
Overload RepairDB to take vector-of-ColumnFamilyDescriptor, which tells
us CF name + options. Also takes a ColumnFamilyOptions for unspecified column
families encountered during the repair.
One potentially confusing thing is that we store options in the constructor and
don't invoke AddColumnFamily() until discovering the CF in ScanTable. This is
because we don't know the CF ID until we find a table belonging to that CF.
Depends on D59781.

Summary:
This diff uses the CF ID and CF name properties in the SST file
to associate recovered data with the proper column family. Depends on D59775.
- In ScanTable(), create column families in VersionSet each time a new one is discovered (via reading SST file properties)
- In ConvertLogToTable(), dump an SST file for every column family with data in the WAL
- In AddTables(), make a VersionEdit per-column family that adds all of that CF's tables

Summary:
To support column families, it is easiest to use VersionSet to manage
our column families (if we don't have Versions then ColumnFamilyData always
behaves as a dummy column family). This diff only refactors the existing repair
logic to use VersionSet; the next two parts will add support for multiple
column families.

Summary:
The main PHP code churn is caused by extracting the common code from `FacebookArcanistConfiguration.php` and `FacebookOldArcanistConfiguration.php` into `RocksDBCommonDeterminator.php`. This is necessary both for reducing the duplication of code and making sure that we can execute the common core logic separately from continuous runs.
The main logic in `RocksDBCommonDeterminator.php` remains quite the same with the exception of some things:
- Adding separation between the cases when a diff is submitted //vs.// when the code is triggered from a continuous run. There are certain actions which we should do in a case of diff only.
- Adding reporting - now the person who authored the diff will receive e-mail notifications if any of the jobs have failed.
- Enabling assertions and making sure that we'll terminate on failure. This is an internal code used by competent engineers, so instead of `if (!condition) { echo "Something"; exit(1); }` for every invariant I think that `assert(condition)` provides better readability with the same behavior. Especially taking into account that we're talking about things which shouldn't ever happen.
Enabling this entire process will be triggered internally and will be a subject of a separate code review. We should discuss the details of triggering continuous RocksDB build and tests on that diff.
Test Plan:
- Make sure that `[p]arc diff` scenario isn't broken by verifying that tests validating this diff will pass.
- Private testing of triggering the continuous build script.
- Once the changes will land then author an internal job which will use the script and verify its validity.

Right now the way we do BlockIter::Prev() is like this
- Go to the beginning of the restart interval
- Keep moving forward (and decoding keys using ParseNextKey()) until we reach the desired key
This can be optimized by caching the decoded entries in the first pass and reusing them in consecutive BlockIter::Prev() calls

Summary:
Two changes here:
- Remove dead Jenkins related code which is no longer relevant.
- Support `arc diff --preview`. Currently it doesn't work because a step which applies a diff assumes that a revision has been created. Which in case of `--preview` isn't. Therefore diff can't be applied and validation fails. Solution is to use `--nocommit` because for validation purposes performing a commit isn't necessary.
Test Plan:
- Current changes are submitted using `arc diff --preview`.
- All the pre-commit verification tests passed.
