Add support for multiple possible bisect results (issue1228, issue1182)
The real reason for both issue is that bisect can not handle cases where there
are multiple possibilities for the result.
Example (from issue1228):
rev 0 -> good
rev 1 -> skipped
rev 2 -> skipped
rev 3 -> skipped
rev 4 -> bad
Note that this patch does not only fix the reported Assertion Error but also
the problem of a non converging bisect:
hg init
for i in `seq 3`; do echo $i > $i; hg add $i; hg ci -m$i; done
hg bisect -b 2
hg bisect -g 0
hg bisect -s
From this state on, you can:
a) mark as bad forever (non converging!)
b) mark as good to get an inconsistent state
c) skip for the Assertion Error

# hg backend for convert extension # Notes for hg->hg conversion: # # * Old versions of Mercurial didn't trim the whitespace from the ends # of commit messages, but new versions do. Changesets created by # those older versions, then converted, may thus have different # hashes for changesets that are otherwise identical. # # * By default, the source revision is stored in the converted # revision. This will cause the converted revision to have a # different identity than the source. To avoid this, use the # following option: "--config convert.hg.saverev=false" import os, time from mercurial.i18n import _ from mercurial.repo import RepoError from mercurial.node import bin, hex, nullid from mercurial import hg, revlog, util from common import NoRepo, commit, converter_source, converter_sink class mercurial_sink(converter_sink): def __init__(self, ui, path): converter_sink.__init__(self, ui, path) self.branchnames = ui.configbool('convert', 'hg.usebranchnames', True) self.clonebranches = ui.configbool('convert', 'hg.clonebranches', False) self.tagsbranch = ui.config('convert', 'hg.tagsbranch', 'default') self.lastbranch = None if os.path.isdir(path) and len(os.listdir(path)) > 0: try: self.repo = hg.repository(self.ui, path) if not self.repo.local(): raise NoRepo(_('%s is not a local Mercurial repo') % path) except RepoError, err: ui.print_exc() raise NoRepo(err.args[0]) else: try: ui.status(_('initializing destination %s repository\n') % path) self.repo = hg.repository(self.ui, path, create=True) if not self.repo.local(): raise NoRepo(_('%s is not a local Mercurial repo') % path) self.created.append(path) except RepoError, err: ui.print_exc() raise NoRepo("could not create hg repo %s as sink" % path) self.lock = None self.wlock = None self.filemapmode = False def before(self): self.ui.debug(_('run hg sink pre-conversion action\n')) self.wlock = self.repo.wlock() self.lock = self.repo.lock() self.repo.dirstate.clear() def after(self): self.ui.debug(_('run hg sink post-conversion action\n')) self.repo.dirstate.invalidate() self.lock = None self.wlock = None def revmapfile(self): return os.path.join(self.path, ".hg", "shamap") def authorfile(self): return os.path.join(self.path, ".hg", "authormap") def getheads(self): h = self.repo.changelog.heads() return [ hex(x) for x in h ] def putfile(self, f, e, data): self.repo.wwrite(f, data, e) if f not in self.repo.dirstate: self.repo.dirstate.normallookup(f) def copyfile(self, source, dest): self.repo.copy(source, dest) def delfile(self, f): try: util.unlink(self.repo.wjoin(f)) #self.repo.remove([f]) except OSError: pass def setbranch(self, branch, pbranches): if not self.clonebranches: return setbranch = (branch != self.lastbranch) self.lastbranch = branch if not branch: branch = 'default' pbranches = [(b[0], b[1] and b[1] or 'default') for b in pbranches] pbranch = pbranches and pbranches[0][1] or 'default' branchpath = os.path.join(self.path, branch) if setbranch: self.after() try: self.repo = hg.repository(self.ui, branchpath) except: self.repo = hg.repository(self.ui, branchpath, create=True) self.before() #
