[metrics-db/master] Download all server/extra-info descriptors once per day.
by karsten＠torproject.org 03 Apr '11

03 Apr '11

commit be6e7c3d4f9f9acdf5e2f459453c23a230c129d0 Author: Karsten Loesing <karsten.loesing(a)gmx.net> Date: Fri Apr 1 15:43:38 2011 +0200 Download all server/extra-info descriptors once per day. The relay descriptor downloader so far only downloads server and extra-info descriptors that are referenced in other directory documents and that we are missing. With this patch we also download /tor/server/all and /tor/extra/all from the directories once per day to learn about server and extra-info descriptors that are not referenced anywhere. This patch further requests the compressed versions of descriptors by adding ".z" to the URLs in order to save bandwidth. This patch is a 50% rewrite of the relay descriptor downloader which became too complex over time. --- config.template | 27 +- src/org/torproject/ernie/db/Configuration.java | 56 ++- src/org/torproject/ernie/db/Main.java | 15 +- .../ernie/db/RelayDescriptorDownloader.java | 857 ++++++++++++-------- 4 files changed, 600 insertions(+), 355 deletions(-) diff --git a/config.template b/config.template index 47a8c8d..d744f25 100644 --- a/config.template +++ b/config.template @@ -24,7 +24,32 @@ # ## Comma separated list of directory authority addresses (IP[:port]) to ## download missing relay descriptors from -#DownloadFromDirectoryAuthorities 86.59.21.38,194.109.206.212,212.112.245.170 +#DownloadFromDirectoryAuthorities 86.59.21.38,216.224.124.114:9030,213.115.239.118:443,193.23.244.244,208.83.223.34:443,128.31.0.34:9131,194.109.206.212,212.112.245.170 +# +## Download the current consensus (only if DownloadRelayDescriptors is 1) +#DownloadCurrentConsensus 1 +# +## Download current votes (only if DownloadRelayDescriptors is 1) +#DownloadCurrentVotes 1 +# +## Download missing server descriptors (only if DownloadRelayDescriptors +## is 1) +#DownloadMissingServerDescriptors 1 +# +## Download missing extra-info descriptors (only if +## DownloadRelayDescriptors is 1) +#DownloadMissingExtraInfoDescriptors 1 +# +## Download all server descriptors from the directory authorities at most +## once a day (only if DownloadRelayDescriptors is 1) +#DownloadAllServerDescriptors 0 +# +## Download all extra-info descriptors from the directory authorities at +## most once a day (only if DownloadRelayDescriptors is 1) +#DownloadAllExtraInfoDescriptors 0 +# +## Compress relay descriptors downloads by adding .z to the URLs +#CompressRelayDescriptorDownloads 0 # ## Import bridge snapshots from disk, if available #ImportBridgeSnapshots 0 diff --git a/src/org/torproject/ernie/db/Configuration.java b/src/org/torproject/ernie/db/Configuration.java index ae24175..b4e6f8b 100644 --- a/src/org/torproject/ernie/db/Configuration.java +++ b/src/org/torproject/ernie/db/Configuration.java @@ -30,8 +30,17 @@ public class Configuration { private boolean importBridgeSnapshots = false;
