1238894 - cli: using mozregression with no arguments triggers a bisection on a 7-year-frame

Status: RESOLVED WONTFIX

(Testing :: mozregression, defect)

Description

[Johan Lorenzo [:jlorenzo]]

STR
1. Run mozregression with no arguments

Results
I don't know if it's an issue that has already been discussed or the current implementation is the expected behavior.

I was trying to find how to use the cli. As I didn't provide any date, I was expecting to get an error message or the output of `mozregression --help`. Instead, I got shown old Firefox (circa 2012) for a split second and then asking me if that build is broken.

After looking more closely to the logs, I understood that a bisection between 2009 and today started.

Well, it is the expected behavior - it is intended since the beginning of mozregression. But maybe now it does not make much sense, and we could default to a one year range (as we do in the GUI, fwiw), or maybe as you said just don't accept no good and bad ?

Though, maybe not providing the bad value (when you want to bisect until today) is interesting.

If it's intended since then, we might break other's people workflow. If that's the case, I don't mind closing this bug as INVALID or WONTFIX. 

Otherwise, not accepting the couple (NO_GOOD, NO_BAD) sounds tangible. I'm not sure how many people would use this "since 1 year ago" hidden feature.

Yeah, let's close this as WONTFIX.
