gendoc: fix localization of help topic
When a topic provides a callable method for its text, most likely
this text will be generated from different parts, so it does not
make sense to apply gettext on the whole result, rather the method
should provide translation by itself.
This is the case with the extensions topic, which triggers a double
gettext call, making the ASCII codec fail when it encounters 8 bit
characters, and prevents the documentation from being built.

'''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 Zeroconf, socket, time, os from mercurial import ui 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: 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): super(hgwebzc, self).__init__(repo, name) name = self.reponame or os.path.basename(repo.root) desc = self.repo.ui.config("web", "description", name) publish(name, desc, name, int(repo.ui.config("web", "port", 8000))) class hgwebdirzc(hgwebdir_mod.hgwebdir): def run(self): for r, p in self.repos: u = self.ui.copy() u.readconfig(os.path.join(p, '.hg', 'hgrc')) n = os.path.basename(r) publish(n, "hgweb", p, int(u.config("web", "port", 8000))) return super(hgwebdirzc, self).run() # 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 v in l.found.values(): n = v.name[:v.name.index('.')] n.replace(" ", "-") u = "http://%s:%s%s" % (socket.inet_ntoa(v.address), v.port, v.properties.get("path", "/")) yield "zc-" + n, u def config(orig, self, section, key, default=None, untrusted=False): if section == "paths" and key.startswith("zc-"): for n, p in getzcpaths(): if n == key: return p return orig(self, section, key, default, untrusted) def configitems(orig, self, section, untrusted=False): r = orig(self, section, untrusted) if section == "paths": r += getzcpaths() return r extensions.wrapfunction(ui.ui, 'config', config) extensions.wrapfunction(ui.ui, 'configitems', configitems) hgweb_mod.hgweb = hgwebzc hgwebdir_mod.hgwebdir = hgwebdirzc
