From: Zooko O'Whielacronx Date: Mon, 1 Aug 2011 18:54:01 +0000 (-0700) Subject: remove get_serverid from DownloadStatus.add_dyhb_request and customers X-Git-Url: https://git.rkrishnan.org/simplejson/components/...?a=commitdiff_plain;h=6b2e7985955fb312cb113f1dde537a99b0107dd3;p=tahoe-lafs%2Ftahoe-lafs.git remove get_serverid from DownloadStatus.add_dyhb_request and customers This patch is a rebase of a patch originally written by Brian. I didn't change any of the intent of Brian's patch, just ported it to current trunk. refs #1363 --- diff --git a/src/allmydata/immutable/downloader/finder.py b/src/allmydata/immutable/downloader/finder.py index 2670a20b..8bcdca76 100644 --- a/src/allmydata/immutable/downloader/finder.py +++ b/src/allmydata/immutable/downloader/finder.py @@ -135,8 +135,7 @@ class ShareFinder: lp = self.log(format="sending DYHB to [%(name)s]", name=server.get_name(), level=log.NOISY, umid="Io7pyg") time_sent = now() - d_ev = self._download_status.add_dyhb_request(server.get_serverid(), - time_sent) + d_ev = self._download_status.add_dyhb_request(server, time_sent) # TODO: get the timer from a Server object, it knows best self.overdue_timers[req] = reactor.callLater(self.OVERDUE_TIMEOUT, self.overdue, req) diff --git a/src/allmydata/immutable/downloader/status.py b/src/allmydata/immutable/downloader/status.py index 977bf2e1..8b1b4f1b 100644 --- a/src/allmydata/immutable/downloader/status.py +++ b/src/allmydata/immutable/downloader/status.py @@ -107,7 +107,7 @@ class DownloadStatus: # self.dyhb_requests tracks "do you have a share" requests and # responses.
