Merge #16878: Fix non-deterministic coverage of test DoS_mapOrphans
4455949d6f0218b40d33d7fe6de6555f8f62192f Make test DoS_mapOrphans deterministic (David Reikher)

Pull request description:

  This pull request proposes a solution to make the test `DoS_mapOrphans` in denialofservice_tests.cpp have deterministic coverage.

  The `RandomOrphan` function in denialofservice_tests.cpp and the implicitly called function `ecdsa_signature_parse_der_lax` in pubkey.cpp were causing the non-deterministic test coverage.

  In the former, if a random orphan was selected the index of which is bigger than the max. orphan index in `mapOrphanTransactions`, the last orphan was returned from `RandomOrphan`. If the random number generated was never large enough, this condition would not be fulfilled and the corresponding branch wouldn't run. The proposed solution is to force one of the 50 dependant orphans to depend on the last orphan in `mapOrphanTransactions` using the newly introduced function `OrphanByIndex` (and passing it a large uint256), forcing this branch to run at least once.

  In the latter, if values for ECDSA `R` or `S` (or both) had no leading zeros, some code would not be executed. The solution was to find a constant signature that would be comprised of `R` and `S` values with leading zeros and calling `CPubKey::Verify` at the end of the test with this signature forcing this code to always run at least once at the end even if it hadn't throughout the test.

  To test that the coverage is (at least highly likely) deterministic, I ran

  `contrib/devtools/test_deterministic_coverage.sh denialofservice_tests/DoS_mapOrphans 1000`

  and the result was deterministic coverage across 1000 runs.

  Also - removed denialofservice_tests test entry from the list of non-deterministic tests in the coverage script.

b3c4d9bac6910f6c28f6008c5ca7064a315fd2a5 test: rename test suite name "tx_validationcache_tests" to match filename (Sebastian Falbesoner)

Pull request description:

  Quoting `src/test/README.md`, '`Adding test cases`':

  >     "The file naming convention is `<source_filename>_tests.cpp`
  >      and such files should wrap their tests in a test suite
  >      called `<source_filename>_tests`."

  Currently the unit test source file `txvalidationcache_tests.cpp` contains a unit test suite with the name `tx_validationcache_tests`, which is fixed by this PR. The following shell script shows that this is the only mismatch and for all other unit test source files the test suite names are correct:

  ```
   #!/bin/bash
   shopt -s globstar
   for test_full_filename in **/*_tests.cpp; do
       test_name_file=`basename $test_full_filename .cpp`
       test_name_suite=`sed -n "s/^.*TEST_SUITE(\(.*_tests\).*$/\1/p" $test_full_filename`
       if [ $test_name_file != $test_name_suite ]; then
           echo "TestFilename: $test_name_file != TestSuitname: $test_name_suite"
       fi
   done
  ```

c061be1e2f tests: Mark unit test blockfilter_index_initial_sync as non-deterministic (practicalswift)

Pull request description:

  Mark unit test `blockfilter_index_tests/blockfilter_index_initial_sync` as non-deterministic.

  Before this PR:

  ```
  $ contrib/devtools/test_deterministic_coverage.sh 500
  [2019-06-04 09:58:57] Measuring coverage, run #1 of 500
  [2019-06-04 10:00:33] Measuring coverage, run #2 of 500
  [2019-06-04 10:02:19] Measuring coverage, run #3 of 500

  The line coverage is non-deterministic between runs. Exiting.

  The test suite must be deterministic in the sense that the set of lines executed at least
  once must be identical between runs. This is a necessary condition for meaningful
  coverage measuring.

dd2f85c084 Merge #15296: tests: Add script checking for deterministic line coverage in unit tests
43206239a8 tests: Add script checking for deterministic line coverage (practicalswift)

Pull request description:

  Add script checking for deterministic line coverage in unit tests.

  Context: #14343 ("coverage reports non-deterministic")

  When the coverage is deterministic this script can be invoked from Travis to guard against regressions, but left inactive for now.

  Output in case of determinism:

  ```
  $ contrib/test_deterministic_coverage.sh 2
  [2019-01-30 20:08:46] Measuring coverage, run #1 of 2
  [2019-01-30 20:10:45] Measuring coverage, run #2 of 2

  Coverage test passed: Deterministic coverage across 2 runs.
  ```

  Output in case of non-determinism:

  ```
  $ contrib/test_deterministic_coverage.sh 2
  [2019-01-30 20:08:46] Measuring coverage, run #1 of 2
  [2019-01-30 20:10:45] Measuring coverage, run #2 of 2

  The line coverage is non-deterministic between runs.

  The test suite must be deterministic in the sense that the set of lines executed at least
  once must be identical between runs. This is a neccessary condition for meaningful coverage
  measuring.
