Diff run since timestamp

[rouke-broersma]

Is your feature request related to a problem? Please describe. It would be nice to be able able to tell stryker to run a test with only mutations new since some timestamp

Describe the solution you'd like Add option to provide a timestamp to the git diff feature. This will look through the commits and choose the closest commit before or on the specified timestamp.

I could have a look at this.

@rouke-broersma a few questions.

• Do we want to introduce a new cli options for this or should this work with the existing since option? Something like --since-time <timestamp>?
• What type of timestamp do we want to except?
  • hh:mm (current day)
  • hh:mm:ss (current day)
  • yyyy-MM-ddThh:mm:ss (uses current timezone)
  • yyyy-MM-ddThh:mm:ss+02:00
  • Epoch Unix Timestamp (?)
• Or do we want to go a for a bit more ease of use like:
  • 30m (30 minutes in the past)
  • 2h (2 hours in the past)
  • 1d (1 day in the past)

Ideally (and this might be super complex), you can pass this with the current --since: option and we don't need a new option. This means parsing the input into the correct type of target. --since is a "SingleOfNoValue" commandline option which means you can optionally supply a value with this flag. This value is currently supposed to be a committish but in my ideal scenario this can be committish, timestamp or whatever else we come up with.

Timestamp could be many formats but I would suggest starting with 'relative time' and maybe ISO8601 timestamp.

hi @danielmertens where do you stand regarding this feature ? if not, could you de-assign yourself as a signal for others to pick up.

In any case, thanks for the time you dedicated to this.
