blackbox: add backup bundle paths to blackbox logs
Writes the backup bundle paths to the blackbox so it's easy to see which
backup bundle is associated with which command when you are debugging an
issue.
Example output:
2013/03/13 10:39:56 durham> strip tip
2013/03/13 10:39:59 durham> saved backup bundle to /data/users/durham/www-hg/.hg/strip-backup/e5fac262363a-backup.hg
2013/03/13 10:40:03 durham> strip tip exited 0 after 7.97 seconds

'''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, dispatch from mercurial import extensions from mercurial.hgweb import server as servermod testedwith = 'internal' # 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 socket.error: 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 socket.error: 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) def zc_create_server(create_server, ui, app): httpd = create_server(ui, app) port = httpd.port try: repos = app.repos except AttributeError: # single repo name = app.reponame or os.path.basename(app.repo.root) path = app.repo.ui.config("web", "prefix", "").strip('/') desc = app.repo.ui.config("web", "description", name) publish(name, desc, path, port) else: # webdir prefix = app.ui.config("web", "prefix", "").strip('/') + '/' for repo, path in repos: u = app.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, port) return httpd # 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) extensions.wrapfunction(servermod, 'create_server', zc_create_server)
