templates: add 'bisect' keyword to return a cset's bisect status This new 'bisect' template expands to a cset's bisection status (good, bad and so on...). There is also a new 'shortbisect' filter that yields a single char representing the cset's bisection status. It uses the two recently-added hbisect.label() and .shortlabel() functions. Example output using the repository in test-bisect2.t, and some made-up state of the 'end at merge' test (with graphlog, it's so explicit): $ hg glog --template '{rev}:{node|short} {bisect}\n' \ -r 'bisect(range)|bisect(ignored)' o 17:228c06deef46: bad | o 16:609d82a7ebae: bad (implicit) | o 15:857b178a7cf3: bad |\ | o 13:b0a32c86eb31: good | | | o 12:9f259202bbe7: good (implicit) | | | o 11:82ca6f06eccd: good | | @ | 10:429fcd26f52d: untested |\ \ | o | 9:3c77083deb4a: skipped | |/ | o 8:dab8161ac8fc: good | | o | 6:a214d5d3811a: ignored |\ \ | o | 5:385a529b6670: ignored | | | o | | 4:5c668c22234f: ignored | | | o | | 3:0950834f0a9c: ignored |/ / o / 2:051e12f87bf1: ignored |/ And now the same with the short label: $ hg log --template '{bisect|shortbisect} {rev}:{node|short}\n' 18:d42e18c7bc9b B 17:228c06deef46 B 16:609d82a7ebae B 15:857b178a7cf3 14:faa450606157 G 13:b0a32c86eb31 G 12:9f259202bbe7 G 11:82ca6f06eccd U 10:429fcd26f52d S 9:3c77083deb4a G 8:dab8161ac8fc 7:50c76098bbf2 I 6:a214d5d3811a I 5:385a529b6670 I 4:5c668c22234f I 3:0950834f0a9c I 2:051e12f87bf1 1:4ca5088da217 0:33b1f9bc8bc5 Signed-off-by: "Yann E.
