From: Leif Ryge Date: Mon, 4 Jan 2016 19:58:55 +0000 (+0000) Subject: wui: improved columns in welcome page server list X-Git-Url: https://git.rkrishnan.org/components/com_hotproperty/%22doc.html/%22news.html/?a=commitdiff_plain;h=refs%2Fpull%2F229%2Fhead;p=tahoe-lafs%2Ftahoe-lafs.git wui: improved columns in welcome page server list As discussed at https://tahoe-lafs.org/trac/tahoe-lafs/ticket/1973 and in previous pull request #129. - replace lengthy timestamps with human-readable deltas (eg 1h 2m 3s) - replace "announced" column with "Last RX" column - remove service column (it always said the same thing, "storage") - fix colspan on 'You are not presently connected' message Previous versions, some with github comments: https://github.com/leif/tahoe-lafs/commit/3fe9053134b2429904f673df561e602a50f83c7e , https://github.com/leif/tahoe-lafs/commit/486dbfc7bd3c0bbba42a6df8e4564601120aec0e , and https://github.com/tahoe-lafs/tahoe-lafs/commit/c89ea625803be36a18bce1af4eef95dcd78bba2b, https://github.com/tahoe-lafs/tahoe-lafs/commit/9fabb924867e164e1c6d4d805761db6c39652cf7, https://github.com/tahoe-lafs/tahoe-lafs/commit/bbd8b42a25f8617c43b8293f3b654b3d060e27b9 Unlike previous attempts, the tests on this one should pass in any timezone. (But like current master, will fail with Nevow >=0.12...) Thanks to an anonymous contributor who wrote some of the tests. --- diff --git a/src/allmydata/interfaces.py b/src/allmydata/interfaces.py index e495c759..31fc6144 100644 --- a/src/allmydata/interfaces.py +++ b/src/allmydata/interfaces.py @@ -417,7 +417,6 @@ class IStorageBroker(Interface): public attributes:: service_name: the type of service provided, like 'storage' - announcement_time: when we first heard about this service last_connect_time: when we last established a connection last_loss_time: when we last lost a connection diff --git a/src/allmydata/storage_client.py b/src/allmydata/storage_client.py index dd9780f2..81dc0042 100644 --- a/src/allmydata/storage_client.py +++ b/src/allmydata/storage_client.py @@ -168,7 +168,6 @@ class NativeStorageServer: the their version information.
