subrepo: compare svn subrepo state to last committed revision
A subversion project revisions are a subset of the repository revisions, you
can ask subversion to update a working directory from one revision to another
without changing anything. Unfortunately, Mercurial will think the
subrepository has changed and will commit it again. To avoid useless commits,
we compare the subrepository state to its actual "parent" revision. To ensure
ascending compatibility with existing subrepositories which might reference
fake revisions, we also keep comparing with the subrepo working directory
revision.
NOTE: not sure if this should go in stable or not.

'''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 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) 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
