mq: use exact matching in the second dirstate walking for efficiency of 'qnew'
'hg qnew' with pattern/-I/-X creates matching object with them, and
uses it twice for 'dirstate.walk()': via 'repo.status()' and
'repo.commit()'.
this may cause full manifest scan in the second 'dirstate.walk()',
even though mq already knows complete target filenames at the first
'dirstate.walk()'.
this patch creates exact matching object also in this case, and use it
at 'repo.commit()' invocation to avoid full manifest scan in the
second 'dirstate.walk()'.
even though 'inclsubs' is added to 'pats' for original matching
object, it is also passed to exact matching object, because
subrepositories are deleted from result of 'dirstate.walk()' at the
end of it.

'''discover and advertise repositories on the local network Zeroconf-enabled repositories will be announced in a network without the need to configure a server or a service. They can be discovered without knowing their actual IP address. To allow other people to discover your repository using run :hg:`serve` in your repository:: $ cd test $ hg serve You can discover Zeroconf-enabled repositories by running :hg:`paths`:: $ hg paths zc-test = http://example.com:8000/test ''' import socket, time, os import Zeroconf from mercurial import ui, hg, encoding, util, dispatch from mercurial import extensions from mercurial.hgweb import hgweb_mod from mercurial.hgweb import hgwebdir_mod # publish server = None localip = None def getip(): # finds external-facing interface without sending any packets (Linux) try: s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.connect(('1.0.0.1', 0)) ip = s.getsockname()[0] return ip except: pass # Generic method, sometimes gives useless results try: dumbip = socket.gethostbyaddr(socket.gethostname())[2][0] if not dumbip.startswith('127.') and ':' not in dumbip: return dumbip except (socket.gaierror, socket.herror): dumbip = '127.0.0.1' # works elsewhere, but actually sends a packet try: s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.connect(('1.0.0.1', 1)) ip = s.getsockname()[0] return ip except: pass return dumbip def publish(name, desc, path, port): global server, localip if not server: ip = getip() if ip.startswith('127.'): # if we have no internet connection, this can happen. return localip = socket.inet_aton(ip) server = Zeroconf.Zeroconf(ip) hostname = socket.gethostname().split('.')[0] host = hostname + ".local" name = "%s-%s" % (hostname, name) # advertise to browsers svc = Zeroconf.ServiceInfo('_http._tcp.local.', name + '._http._tcp.local.', server = host, port = port, properties = {'description': desc, 'path': "/" + path}, address = localip, weight = 0, priority = 0) server.registerService(svc) # advertise to Mercurial clients svc = Zeroconf.ServiceInfo('_hg._tcp.local.', name + '._hg._tcp.local.', server = host, port = port, properties = {'description': desc, 'path': "/" + path}, address = localip, weight = 0, priority = 0) server.registerService(svc) class hgwebzc(hgweb_mod.hgweb): def __init__(self, repo, name=None, baseui=None): super(hgwebzc, self).__init__(repo, name=name, baseui=baseui) name = self.reponame or os.path.basename(self.repo.root) path = self.repo.ui.config("web", "prefix", "").strip('/') desc = self.repo.ui.config("web", "description", name) publish(name, desc, path, util.getport(self.repo.ui.config("web", "port", 8000))) class hgwebdirzc(hgwebdir_mod.hgwebdir): def __init__(self, conf, baseui=None): super(hgwebdirzc, self).__init__(conf, baseui=baseui) prefix = self.ui.config("web", "prefix", "").strip('/') + '/' for repo, path in self.repos: u = self.ui.copy() u.readconfig(os.path.join(path, '.hg', 'hgrc')) name = os.path.basename(repo) path = (prefix + repo).strip('/') desc = u.config('web', 'description', name) publish(name, desc, path, util.getport(u.config("web", "port", 8000))) # listen class listener(object): def __init__(self): self.found = {} def removeService(self, server, type, name): if repr(name) in self.found: del self.found[repr(name)] def addService(self, server, type, name): self.found[repr(name)] = server.getServiceInfo(type, name) def getzcpaths(): ip = getip() if ip.startswith('127.'): return server = Zeroconf.Zeroconf(ip) l = listener() Zeroconf.ServiceBrowser(server, "_hg._tcp.local.", l) time.sleep(1) server.close() for value in l.found.values(): name = value.name[:value.name.index('.')] url = "http://%s:%s%s" % (socket.inet_ntoa(value.address), value.port, value.properties.get("path", "/")) yield "zc-" + name, url def config(orig, self, section, key, default=None, untrusted=False): if section == "paths" and key.startswith("zc-"): for name, path in getzcpaths(): if name == key: return path return orig(self, section, key, default, untrusted) def configitems(orig, self, section, untrusted=False): repos = orig(self, section, untrusted) if section == "paths": repos += getzcpaths() return repos def defaultdest(orig, source): for name, path in getzcpaths(): if path == source: return name.encode(encoding.encoding) return orig(source) def cleanupafterdispatch(orig, ui, options, cmd, cmdfunc): try: return orig(ui, options, cmd, cmdfunc) finally: # we need to call close() on the server to notify() the various # threading Conditions and allow the background threads to exit global server if server: server.close() extensions.wrapfunction(dispatch, '_runcommand', cleanupafterdispatch) extensions.wrapfunction(ui.ui, 'config', config) extensions.wrapfunction(ui.ui, 'configitems', configitems) extensions.wrapfunction(hg, 'defaultdest', defaultdest) hgweb_mod.hgweb = hgwebzc hgwebdir_mod.hgwebdir = hgwebdirzc
