transaction: always remove empty journal on abort
When transactions without entries were aborted, the journal (of size 0) was not
unlinked, which prevents subsequent operations until hg recover is run on the
repository.
We also make sure the journal is unlinked when committing, even if the provided
hook doesn't do so.

'''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) path = self.repo.ui.config("web", "prefix", "").strip('/') desc = self.repo.ui.config("web", "description", name) publish(name, desc, path, int(repo.ui.config("web", "port", 8000))) class hgwebdirzc(hgwebdir_mod.hgwebdir): def __init__(self, conf, baseui=None): super(hgwebdirzc, self).__init__(conf, 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, int(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 extensions.wrapfunction(ui.ui, 'config', config) extensions.wrapfunction(ui.ui, 'configitems', configitems) hgweb_mod.hgweb = hgwebzc hgwebdir_mod.hgwebdir = hgwebdirzc
