[stem/master] Parsing dirreq-v*-direct-dl and dirreq-v*-tunneled-dl lines
commit bbf0e80cf889cc4b0738acf93c698fc54720c767 Author: Damian Johnson <atagar@torproject.org> Date: Sun May 13 13:35:33 2012 -0700 Parsing dirreq-v*-direct-dl and dirreq-v*-tunneled-dl lines Parsing four extrainfo descriptor fields related to directory mirroring stat collection. These are similar to dirreq-v*-resp in that they're key=value mappings, with largely known key sets. --- stem/descriptor/extrainfo_descriptor.py | 69 ++++++++++++++++++++++--- test/integ/descriptor/extrainfo_descriptor.py | 6 ++ test/unit/descriptor/extrainfo_descriptor.py | 45 ++++++++++++++++- 3 files changed, 111 insertions(+), 9 deletions(-) diff --git a/stem/descriptor/extrainfo_descriptor.py b/stem/descriptor/extrainfo_descriptor.py index d1967a9..9493f2b 100644 --- a/stem/descriptor/extrainfo_descriptor.py +++ b/stem/descriptor/extrainfo_descriptor.py @@ -24,6 +24,16 @@ DirResponses - known statuses for ExtraInfoDescriptor's dir_*_responses |- NOT_MODIFIED - network status unmodified since If-Modified-Since time +- BUSY - directory was busy +DirStats - known stats for ExtraInfoDescriptor's dir_*_direct_dl and dir_*_tunneled_dl + |- COMPLETE - requests that completed successfully + |- TIMEOUT - requests that didn't complete within a ten minute timeout + |- RUNNING - requests still in procress when measurement's taken + |- MIN - smallest rate at which a descriptor was downloaded in B/s + |- MAX - largest rate at which a descriptor was downloaded in B/s + |- D1-4 and D6-9 - rate of the slowest x/10 download rates in B/s + |- Q1 and Q3 - rate of the slowest and fastest querter download rates in B/s + +- MD - median download rate in B/s + parse_file - Iterates over the extra-info descriptors in a file.
