Description Matthew Hanson 2014-10-29 15:53:19 PDT
bisect-builds should only attempt to bisect the subset of nightlies that ships a framework for the version of OS X that bisect-builds is running on.

For Yosemite, this corresponds to nightlies created at or after r174650.
For Mavericks, this corresponds to nightlies created at or after r157846.
For Mountain Lion, this corresponds to nightlies created at or after r122421.

r=me with the comments resolved.

+1 for the performance optimization.  :)

Typo:  nifhtlies => nightlies

Should this turn into an elsif?  There's no need to re-run the code in this block for 10.8, 10.9 or 10.10.

    } elsif ($osxVersion ge v10.5) {

If we wanted to be thorough, we could also add a FIXME comment for v10.6 and v10.7, but it probably doesn't matter at this point.

This line needs to change to:

        if ($safariVersionString eq "4 Public Beta") {

> Tools/Scripts/bisect-builds:375
>              die "Requires Safari 2.0 or newer";

You could change the die statement below this patch context to be:

        die "Requires Mac OS X 10.4 (Tiger) or later";
