sdong ee9bdd38a1 Script to check whether RocksDB can read DB generated by previous releases and vice versa
Summary: Add a script, which checks out changes from a list of tags, build them and load the same data into it. In the last, checkout the target build and make sure it can successfully open DB and read all the data. It is implemented through ldb tool, because ldb tool is available from all previous builds so that we don't have to cross build anything.

Test Plan: Run the script.

Summary: Now trivial move is only triggered when moving from level n to n+1. With dynamic level base, it is possible that file is moved from level 0 to level n, while levels from 1 to n-1 are empty. Extend trivial move to this case.

Jim Meyering e3ee98b38a run 'make check's rules (and even subtests) in parallel
Summary:
When GNU parallel is available, "make check" tests are now run in parallel.
When /dev/shm is usable, we tell those tests to create temporary files therein.
Now, the longest-running single test, db_test, (which is composed of hundreds of sub-tests)
is no longer run sequentially: instead, each of its sub-tests is run independently, and can
be parallelized along with all other tests. To make that process easier, this change
creates a temporary directory, "t/", in which it puts a small script for each of those
subtests. The output from each parallel-run test is now saved in t/log-TEST_NAME.

When GNU parallel is not available, we run the tests in sequence, just as before.
If GNU parallel is available and you don't like the default of running one subtest
per core, you can invoke "make J=1 check" to run only one test at a time.
Beware: this will take a long time, and it starts with the two longest-running tests, so you
will wait for a long time before seeing any results. Instead, if you want to use fewer resources
but still see useful progress, try "make J=60% check". That will attempt to ensure that 60% of
the cores are occupied by test runs.

To watch progress of individual tests (duration, success (PASS-or-FAIL), name), run "make watch-log"
in the same directory from another window.  That will start with something like this:

and when complete should show numbers/names like this:

  Every 0.1s: sort -k7,7nr -k4,4gr LOG|perl -n -e '@a=split("\t",$_,-1); $t=$a[8]; $t =~ s,^\./,,;' -e '$t =~ s, >.*,,; chomp $t;' -e '$t =~ /.*--gtest_filter=...  Wed Apr  1 10:51:42 2015

Test Plan:

Also changes fillseq to compress all levels to avoid write-amp from rewriting
uncompressed files when they reach the first level to compress.

Increase max_write_buffer_number to avoid stalls during fillseq and make
max_background_flushes agree with max_write_buffer_number.

Jim Meyering d2a92c13bc avoid returning a number-of-active-keys estimate of nearly 2^64
Summary:
If accumulated_num_non_deletions_ were ever smaller than
accumulated_num_deletions_, the computation of
"accumulated_num_non_deletions_ - accumulated_num_deletions_"
would result in a logically "negative" value, but since
the two operands are unsigned (uint64_t), the result corresponding
to e.g., -1 would 2^64-1.

Instead, return 0 in that case.

Test Plan:
  - ensure "make check" still passes
  - temporarily add an "abort();" call in the new "if"-block, and
      observe that it fails in some test cases.  However, note that
      this case is triggered only when the two numbers are equal.
      Thus, no test case triggers the erroneous behavior this
      change is designed to avoid. If anyone can construct a
      scenario in which that bug would be triggered, I'll be
      happy to add a test case.

Mark Callaghan 99ec2412e5 Make the benchmark scripts configurable and add tests
Summary:
This makes run_flash_bench.sh configurable. Previously it was hardwired for 1B keys and tests
ran for 12 hours each. That kept me from using it. This makes it configuable, adds more tests,
makes the duration per-test configurable and refactors the test scripts.

Adds the seekrandomwhilemerging test to db_bench which is the same as seekrandomwhilewriting except
the writer thread does Merge rather than Put.

Forces the stall-time column in compaction IO stats to use a fixed format (H:M:S) which makes
it easier to scrape and parse. Also adds an option to AppendHumanMicros to force a fixed format.
Sometimes automation and humans want different format.

Calls thread->stats.AddBytes(bytes); in db_bench for more tests to get the MB/sec summary
stats in the output at test end.

Adds the average ingest rate to compaction IO stats. Output now looks like:
https://gist.github.com/mdcallag/2bd64d18be1b93adc494

More information on the benchmark output is at https://gist.github.com/mdcallag/db43a58bd5ac624f01e1

For benchmark.sh changes default RocksDB configuration to reduce stalls:
* min_level_to_compress from 2 to 3
* hard_rate_limit from 2 to 3
* max_grandparent_overlap_factor and max_bytes_for_level_multiplier from 10 to 8

Igor Canadi d61cb0b9de db_bench can now disable flashcache for background threads
Summary: Most of the approach is copied from WebSQL's MySQL branch. It's nice that we can do this without touching core RocksDB code.

Test Plan: Compiles and runs. Didn't test flashback code, as I don't have flashback device and most if it is c/p

Jim Meyering 1c47c433ba build: always attempt to update util/build_version.cc
Summary:
This fixes two bugs: "make clean" would never remove the generated
file, util/build_version.cc, and since D33591, would be regenerated
only if it were absent.
* Makefile (clean): Remove the generated file.
(util/build_version.cc): Depend on the no-prereq FORCE target,
so that this target's rules are always run.
Since this is a generated file, make it read-only.
Also, be sure to remove the temporary file when it is the same
as the original.

Test Plan:
Ensure that we attempt regeneration every time.
Make it empty with an up-to-date time stamp and demonstrate
that it is rebuilt with the expected content:

  $ : > util/build_version.cc
  $ make util/build_version.o
   GEN      util/build_version.cc
   GEN      util/build_version.d
   GEN      util/build_version.cc
   CC       util/build_version.o
  $ cat util/build_version.cc
  #include "build_version.h"
  const char* rocksdb_build_git_sha = "rocksdb_build_git_sha:v3.10-2-gb30e72a";
  const char* rocksdb_build_git_date = "rocksdb_build_git_date:2015-03-27";
  const char* rocksdb_build_compile_date = __DATE__;

Herman Lee e018892bb6 Formalize the DB properties string definitions.
Summary:
Assign the string properties to const string variables under the
DB::Properties namespace. This helps catch typos during compilation and
also consolidates the property definition in one place.

Yueh-Hsuan Chiang cfa576402c Make auto_sanity_test always use the db_sanity_test.cc of the newer commit.
Summary:
Whenever we add new tests in db_sanity_test.cc, the verification test
will fail since the old version db_sanity_test.cc does not have the
newly added test.  This patch makes auto_sanity_test.sh always use
the db_sanity_test.cc of the newer commit.

As a result, a macro guard is added to allow db_sanity_test.cc to be
backward compatible.

Test Plan: tools/auto_sanity_check.sh

Jim Meyering ff1ff7c624 TSAN: avoid new link failure with -pg
Summary:
* Makefile (COMPILE_WITH_TSAN): Avoid a link failure by disabling
-pg when building with TSAN enabled.
Now that "make check" builds all $(PROGRAMS), it is linking
a few programs that were not normally linked before.
For example, this would fail to link with the following diagnostic:

  COMPILE_WITH_TSAN=1 make -j40 log_and_apply_bench

    CCLD     log_and_apply_bench
  ld: /usr/lib/../lib64/gcrt1.o: relocation R_X86_64_32S against `__libc_csu_fini' can not be used when making a shared object; recompile with -fPIC
  /usr/lib/../lib64/gcrt1.o: error adding symbols: Bad value
  collect2: error: ld returned 1 exit status
  Makefile:511: recipe for target 'log_and_apply_bench' failed
  make: *** [log_and_apply_bench] Error 1

Since removing -pg is sufficient to get past this link
failure, and no one cares about profiling TSAN-enabled
binaries anyway, we will refrain from linking with -pg
when TSAN testing is enabled.  Use a new variable, "pg"
which is set to "-pg" in most cases, but that is made
empty when COMPILE_WITH_TSAN is set.

Test Plan:
  Now, this succeeds:

    rm -f log_and_apply_bench
    COMPILE_WITH_TSAN=1 make -j40 log_and_apply_bench

Jim Meyering ca25e86efc build: cause the "check" rule to depend on $(PROGRAMS)
Summary:
* Makefile (check): Cause "make check" to build all $(PROGRAMS),
so that it verifies that the few benchmark-only source files that
not already built via "make check" do compile and link successfully.

Test Plan:
run "make clean; make check", and verify that
table/table_reader_bench.cc is now compiled.
Before, it was not, which led to an incomplete fix
for a build break.
