bisect.sh patch

finding fixes and regressions on hg is a pita, but hg bisect does make things nice. This is a working script I have started using to test new javascript tests and to find fixes and regressions on mozilla-central and tracemonkey. It doesn't yet support CVS but that should be possible as well.

An example session follows:

$ bisect.sh 
usage: bisect.sh -p product -b branch -e extra\
                   -T  buildtype \
                   -t test \
                   -S string \
                   -G good -B bad \
                   [-J javascriptoptions]

    variable            description
    ===============     ============================================================
    -p bisect_product     one of js, firefox
    -b bisect_branches    one of branches 1.8.0, 1.8.1, 1.9.0, 1.9.1
    -e bisect_extra       optional. extra qualifier to pick build tree and mozconfig.
    -T bisect_buildtype   one of build types opt debug
    -t bisect_test        Test to be bisected.
    -S bisect_string      optional. String containing a regular expression which 
                          can be used to distinguish different failures for the given
                          test. The script will search the failure log for the pattern 
                          "$bisect_test.*$string" to determine if a test failure
                          matches the expected failure.
                          bisect_string can contain any extended regular expressions 
                          supported by egrep.
    -G bisect_good        For branches 1.8.0, 1.8.1, 1.9.0, date test passed
                          For branch 1.9.1, revision test passed
    -B bisect_bad         For branches, 1.8.0, 1.8.1, 1.9.0 date test failed
                          For branch 1.9.1, revision test failed. 

       If the good revision (test passed) occurred  prior to the bad revision 
       (test failed), the script will search for the first bad revision which 
       caused the test to regress.

       If the bad revision (test failed) occurred prior to the good revision 
       (test passed), the script will search for the first good revision which 
       fixed the failing test.
       
    -J javascriptoptions  optional. Set JavaScript options:
         -Z n Set gczeal to n. Currently, only valid for 
              debug builds of Gecko 1.8.1.15, 1.9.0 and later.
         -z optional. use split objects in the shell.
         -j optional. use JIT in the shell. Only available on 1.9.1 and later
