Performance

Issues: #166, #42

Improve performance by eliminating the actively waiting while loops (#42) (@0mp)

The changes in the source code are available here.

• Removed the while loops which were actively waiting.
• Introduced a condiditon variable which is shared between threads. It allows:
• the application thread to go to sleep if:
  • there are no new points to process;
  • the set of points collected so far is not ready to be treated as one symbol;
• the listener thread
  • to wake up the application thread if it added a new point onto the queue.
• The performance increased significantly; before this improvement the app took 100% of the CPU time and now it dropped down to 2%.

Tests (@piotrekp1)

Issues: #143

Split classifier functions into smaller functions, created tests for classifier

Refactoring (@piotrekp1)

Issues: #138, #166, #143

#138 (@piotrekp1)

Changed the way we open files in classifier from 'open do close' to 'with open'.

(#143) (@piotrekp1)

Didn't refactor classifier, couldn't find a convenient way (or at least good enough to not be refactored week after) to refactor it.

(#166) (@piotrekp1)

Didn't do it because we planned to first refactor Classifier, and I didn't manage to refactor it.
