See what's changed since your last review with iterative review

When a pull request is updated, Bitbucket Server will show you what has changed since you last reviewed it.

For reviewers, this means no more hunting through files for edits or re-reviewing code you've already seen. Upon returning to the updated review, Bitbucket Server will automatically display the number of commits since your last review and a corresponding diff. This allows you to comment on only those unreviewed commits. 

For authors, getting that second review after you've incorporated feedback is less painful. So you can merge your changes with confidence that each change was reviewed.

You can read all about conducting code reviews with pull requests on the page Review and discuss a pull request.

Adaptive throttling of SCM hosting operations

Bitbucket Server 4.11 introduced a new throttling approach for SCM hosting operations that adapts to the stress the machine is under, referred to as adaptive throttling. With adaptive throttling, Bitbucket examines the total physical memory on the machine and determines a maximum ticket number that the machine can safely support given an estimate of how much memory a hosting operation consumes, how much memory BBS needs, and how much search needs. The default minimum (1 ticket per CPU core) and maximum (12 tickets per CPU core) of the ticket range can be changed.

Other characteristics of adaptive resource throttling:

  • Allows a variable range of ticket values depending on how close current CPU usage is to a target CPU usage (defaults to 75% CPU usage). This can be changed.
  • Every 5 seconds it resamples the CPU usage and recalculates how many tickets within the range can be supported.
  • CPU readings are smoothed so as to not respond too suddenly to CPU spikes and overshoot/undershoot the optimum number of tickets.
