# 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() #
