c99541828f Remove the re-search on depth 0. It is correctly handled by search now. 2020-09-25 16:06:33 +02:00

b6e7733b4c In gensfen call search before get_current_game_result so that rootMoves is initialized by Learner::init_for_search. Don't call Tablebases::rank_root_moves in get_current_game_result because it's called in Learner::init_for_search. This fixes accessing uninitialized variables related to tablebases. 2020-09-25 15:04:21 +02:00

e8472b5fbe Fix races in gensfen as detected with thread sanitizer. 
RootInTB was an incorrectly shared global, probably leading to wrong scoreing

Minor:
 setting TB global state from input by all threads (all threads write same values)
 setting Limits global state by all threads (idem)
 thread counting for finalization

CI can be enabled once races are fixed in the learner, manually goes like:
```
make clean && make -j2 ARCH=x86-64-modern sanitize=thread    optimize=no debug=yes build
../tests/instrumented_learn.sh --sanitizer-thread
```

Needs some review.

fixes a small issue, with ponder

Probably the learning command can be improved a bit, so that despite the limited data, the code coverage is better.
