From: Brian Warner Date: Tue, 22 May 2012 04:18:25 +0000 (-0700) Subject: UploadResults: store IServers internally, but still return serverids X-Git-Url: https://git.rkrishnan.org/%5B/frontends/about.html?a=commitdiff_plain;h=843739486a71a0f3cbf534dd774950ae7928e867;p=tahoe-lafs%2Ftahoe-lafs.git UploadResults: store IServers internally, but still return serverids This stores IDisplayableServer-providing instances (StubServers or NativeStorageServers) in the .servermap and .sharemap dictionaries. But get_servermap()/get_sharemap() still return data structures with serverids, not IServers, by translating their data on the way out. This lets us put off changing the callers for a little bit longer. --- diff --git a/src/allmydata/immutable/upload.py b/src/allmydata/immutable/upload.py index 81f18a8f..c609d37f 100644 --- a/src/allmydata/immutable/upload.py +++ b/src/allmydata/immutable/upload.py @@ -64,8 +64,8 @@ class UploadResults: ciphertext_fetched, # how much the helper fetched preexisting_shares, # count of shares already present pushed_shares, # count of shares we pushed - sharemap, # {shnum: set(serverid)} - servermap, # {serverid: set(shnum)} + sharemap, # {shnum: set(server)} + servermap, # {server: set(shnum)} timings, # dict of name to number of seconds uri_extension_data, uri_extension_hash, @@ -95,9 +95,17 @@ class UploadResults: def get_pushed_shares(self): return self._pushed_shares def get_sharemap(self): - return self._sharemap + # returns {shnum: set(serverid)} + sharemap = {} + for shnum, servers in self._sharemap.items(): + sharemap[shnum] = set([s.get_serverid() for s in servers]) + return sharemap def get_servermap(self): - return self._servermap + # returns {serverid: set(shnum)} + servermap = {} + for server, shnums in self._servermap.items(): + servermap[server.get_serverid()] = set(shnums) + return servermap def get_timings(self): return self._timings def get_uri_extension_data(self): @@ -144,6 +152,8 @@ class ServerTracker: return ("" % (self._server.get_name(), si_b2a(self.storage_index)[:5])) + def get_server(self): + return self._server def get_serverid(self): return self._server.get_serverid() def get_name(self): @@ -1025,10 +1035,9 @@ class CHKUploader: sharemap = dictutil.DictOfSets() servermap = dictutil.DictOfSets() for shnum in e.get_shares_placed(): - server_tracker = self._server_trackers[shnum] - serverid = server_tracker.get_serverid() - sharemap.add(shnum, serverid) - servermap.add(serverid, shnum) + server = self._server_trackers[shnum].get_server() + sharemap.add(shnum, server) + servermap.add(server, shnum) now = time.time() timings = {} timings["total"] = now - self._started @@ -1187,8 +1196,9 @@ class RemoteEncryptedUploadable(Referenceable): class AssistedUploader: - def __init__(self, helper): + def __init__(self, helper, storage_broker): self._helper = helper + self._storage_broker = storage_broker self._log_number = log.msg("AssistedUploader starting") self._storage_index = None self._upload_status = s = UploadStatus() @@ -1307,13 +1317,22 @@ class AssistedUploader: now = time.time() timings["total"] = now - self._started + gss = self._storage_broker.get_stub_server + sharemap = {} + servermap = {} + for shnum, serverids in hur.sharemap.items(): + sharemap[shnum] = set([gss(serverid) for serverid in serverids]) + # if the file was already in the grid, hur.servermap is an empty dict + for serverid, shnums in hur.servermap.items(): + servermap[gss(serverid)] = set(shnums) + ur = UploadResults(file_size=self._size, # not if already found ciphertext_fetched=hur.ciphertext_fetched, preexisting_shares=hur.preexisting_shares, pushed_shares=hur.pushed_shares, - sharemap=hur.sharemap, - servermap=hur.servermap, # not if already found + sharemap=sharemap, + servermap=servermap, timings=timings, uri_extension_data=hur.uri_extension_data, uri_extension_hash=hur.uri_extension_hash, @@ -1554,8 +1573,9 @@ class Uploader(service.MultiService, log.PrefixingLogMixin): else: eu = EncryptAnUploadable(uploadable, self._parentmsgid) d2 = defer.succeed(None) + storage_broker = self.parent.get_storage_broker() if self._helper: - uploader = AssistedUploader(self._helper) + uploader = AssistedUploader(self._helper, storage_broker) d2.addCallback(lambda x: eu.get_storage_index()) d2.addCallback(lambda si: uploader.start(eu, si)) else: diff --git a/src/allmydata/test/test_helper.py b/src/allmydata/test/test_helper.py index 909e3e5d..e1fd54db 100644 --- a/src/allmydata/test/test_helper.py +++ b/src/allmydata/test/test_helper.py @@ -89,6 +89,8 @@ class FakeClient(service.MultiService): def get_encoding_parameters(self): return self.DEFAULT_ENCODING_PARAMETERS + def get_storage_broker(self): + return self.storage_broker def flush_but_dont_ignore(res): d = flushEventualQueue() @@ -114,8 +116,8 @@ class AssistedUpload(unittest.TestCase): timeout = 240 # It takes longer than 120 seconds on Francois's arm box. def setUp(self): self.s = FakeClient() - self.storage_broker = StorageFarmBroker(None, True) - self.secret_holder = client.SecretHolder("lease secret", "convergence") + self.s.storage_broker = StorageFarmBroker(None, True) + self.s.secret_holder = client.SecretHolder("lease secret", "converge") self.s.startService() self.tub = t = Tub() @@ -129,8 +131,8 @@ class AssistedUpload(unittest.TestCase): def setUpHelper(self, basedir, helper_class=Helper_fake_upload): fileutil.make_dirs(basedir) self.helper = h = helper_class(basedir, - self.storage_broker, - self.secret_holder, + self.s.storage_broker, + self.s.secret_holder, None, None) self.helper_furl = self.tub.registerReference(h)
