Query: ConE: A Concurrent Edit Detection Tool for Large Scale Software
  Development   Modern, complex software systems are being continuously extended and
adjusted. The developers responsible for this may come from different teams or
organizations, and may be distributed over the world. This may make it
difficult to keep track of what other developers are doing, which may result in
multiple developers concurrently editing the same code areas. This, in turn,
may lead to hard-to-merge changes or even merge conflicts, logical bugs that
are difficult to detect, duplication of work, and wasted developer
productivity. To address this, we explore the extent of this problem in the
pull request based software development model. We study half a year of changes
made to six large repositories in Microsoft in which at least 1,000 pull
requests are created each month. We find that files concurrently edited in
different pull requests are more likely to introduce bugs. Motivated by these
findings, we design, implement, and deploy a service named ConE (Concurrent
Edit Detector) that proactively detects pull requests containing concurrent
edits, to help mitigate the problems caused by them. ConE has been designed to
scale, and to minimize false alarms while still flagging relevant concurrently
edited files. Key concepts of ConE include the detection of the Extent of
Overlap between pull requests, and the identification of Rarely Concurrently
Edited Files. To evaluate ConE, we report on its operational deployment on 234
repositories inside Microsoft. ConE assessed 26,000 pull requests and made 775
recommendations about conflicting changes, which were rated as useful in over
70% (554) of the cases. From interviews with 48 users we learned that they
believed ConE would save time in conflict resolution and avoiding duplicate
work, and that over 90% intend to keep using the service on a daily basis.
