ab0f3b964f crash_test to trigger some less frequent crash point more frequently
Summary: crash_test still has a very low chance to hit some crash point. Have another mode for covering them more likely.

Test Plan: Run crash_test and see db_stress is called with expected prameters.

4575de5b9e #7916298: merge tools/db_crashtest2.py into tools/db_crashtest.py
Summary:
merge tools/db_crashtest2.py into tools/db_crashtest.py

python tools/db_crashtest.py -h  # show help message, ALL parameters can be overwrite by arguments

Example usages:
python tools/db_crashtest.py blackbox  # run blackbox with default parameters
python tools/db_crashtest.py blackbox --simple
python tools/db_crashtest.py whitebox  # run whitebox with default parameters
python tools/db_crashtest.py whitebox --simple

all default parameters are identical to previous version.

Test Plan: `make crash_test` and make sure it can run with expected parameters pased to db_stress.

680156ca61 crash_test to run with data sync on
Summary: Mode of data sync off is a much less used than the case of data sync on. Crash test should cover the more common case than a corner case. So turn data sync on in crash tests.

Test Plan: Run crash test and make sure it can run with expected parameters pased to db_stres.

cf3e05304f crash_test cleans up directory before testing if TEST_TMPDIR is set
Summary: In a recent change, crash_test can put data under TEST_TMPDIR. However, the directory is not cleaned before running the test, which may cause unexpected results. Clean it.

Test Plan: Run white and black box crash test against non-existing, or non-empty but not compactible DBs, and make sure it works as expected.

2e73bd4ff2 crash_test to put DB under TEST_TMPDIR
Summary: Currently crash_test only puts data under /tmp. It is less flexible if we want to cover different file systems or media. Make crash_test to appreciate TEST_TMPDIR so that users can run it against another file system.

Test Plan: Run blackbox_crash_test and whitebox_crash_test with or without TEST_TMPDIR set and make sure DBs are put in the right place

1205bdbcee crash_test to cover simply cases
Summary:
crash_test now only runs complicated options, multiple column families, prefix hash, frequently changing options, many compaction threads, etc. These options are good to cover new features but we loss coverage in most common use cases. Furthermore, by running only for multiple column families, we are not able to create LSM trees that are large enough to cover some stress cases.
Make half of crash_test runs the simply tests: single column family, default mem table, one compaction thread, no change options.

Test Plan: Run crash_test

d4a8423334 Remove seek compaction
Summary:
As discussed in our internal group, we don't get much use of seek compaction at the moment, while it's making code more complicated and slower in some cases.

This diff removes seek compaction and (hopefully) all code that was introduced to support seek compaction.

There is one test case that relied on didIO information. I'll try to find another way to implement it.

Test Plan: make check

4cfb0eb40f Delete rocksdb dir after crashtest
Summary:
We should clean up after ourselves. Last crashtest failed because the disk on the cibuild machine was full.

Also, db_crashtest is supposed to run the test on the same database in every iteration. This isn't the case currently, because every run creates a new tmp directory. It's fixed with this diff.

Test Plan: ran it

97eddef235 Reopen DB in crash test
Summary:
Why don't we automatically reopen DB when running crash test (running in our nightly build)? If I understand correctly, crashtest is manually reopenning the DB, but then the DB does not check its consistency when you kill db_stress process and then re-run it again.
Does this make sense?

af732c7ba8 Add universal compaction to db_stress nightly build
Summary:
Most code change in this diff is code cleanup/rewrite. The logic changes include:

(1) add universal compaction to db_crashtest2.py
(2) randomly set --test_batches_snapshots to be 0 or 1 in db_crashtest2.py. Old codes always use 1.
(3) use different tmp directory as db directory in different runs. I saw some intermittent errors in my local tests. Use of different tmp directory seems to be able to solve the issue.

Test Plan: Have run "make crashtest" for multiple times. Also run "make all check"

2b9a360c8b [Getting warning while running db_crashtest]
Summary:
When I run db_crashtest, I am seeing lot of warnings that say db_stress completed
before it was killed. To fix that I made ops per thread a very large value so that it keeps
running until it is killed.

I also set #reopens to 0. Since we are killing the process anyway, the 'simulated crash'
that happens during reopen may not add additional value.

I usually see 10-25K ops happening before the kill. So I increased max_key from 100 to
1000 so that we use more distinct keys.

Test Plan:
Ran a few times.

e937d47180 Python script to periodically run and kill the db_stress test
Summary: The script runs and kills the stress test periodically. Default values have been used in the script now. Should I make this a part of the Makefile or automated rocksdb build? The values can be easily changed in the script right now, but should I add some support for variable values or input to the script? I believe the script achieves its objective of unsafe crashes and reopening to expect sanity in the database.
