From: Mark Berger Date: Tue, 23 Jul 2013 16:53:22 +0000 (-0400) Subject: Adds _servers_with_shares to ServermapUpdater X-Git-Tag: allmydata-tahoe-1.10.1a1~78 X-Git-Url: https://git.rkrishnan.org/webform_css?a=commitdiff_plain;h=db12f1cffbdb4a2f549e316ef4444d11b23c7e7b;p=tahoe-lafs%2Ftahoe-lafs.git Adds _servers_with_shares to ServermapUpdater When calculating the query boundary for updates to mutable files, instead of using servers that used to have shares, use servers we have added to the servermap. This way the querying process won't finish until we have finished interacting with the servers that have shares. This fixes the race condition which sometimes caused the querying process to finish before the updater was done talking to servers with shares. --- diff --git a/src/allmydata/mutable/servermap.py b/src/allmydata/mutable/servermap.py index 149e1a25..84ac1b5a 100644 --- a/src/allmydata/mutable/servermap.py +++ b/src/allmydata/mutable/servermap.py @@ -483,6 +483,7 @@ class ServermapUpdater: self.full_serverlist = full_serverlist # for use later, immutable self.extra_servers = full_serverlist[:] # servers are removed as we use them self._good_servers = set() # servers who had some shares + self._servers_with_shares = set() #servers that we know have shares now self._empty_servers = set() # servers who don't have any shares self._bad_servers = set() # servers to whom our queries failed @@ -865,6 +866,7 @@ class ServermapUpdater: # Add the info to our servermap. timestamp = time.time() self._servermap.add_new_share(server, shnum, verinfo, timestamp) + self._servers_with_shares.add(server) return verinfo @@ -1127,7 +1129,7 @@ class ServermapUpdater: found_boundary = True break - elif server in self._good_servers: + elif server in self._servers_with_shares: # yes shares states.append("1") #self.log("loop [%s]: 1" % server.get_name()
