[dropping fr-2012 in bcc in exchange for fr-tech]
Fundraising should be able to make the switch fairly quickly. It should also eliminate of the the annoying little bugs as well. In actuality, our code shouldn't notice as a tab is whitespace. :-)
Thanks Diederik.

Apologies for crossposting
Heya,
The Analytics Team is planning to deploy "tab as field delimiter" to replace the current space as fielddelimiter on the varnish/squid/nginx servers. We would like to do this on February 1st. The reason for this change is that we need to have a consistent number of fields in each webrequest log line. Right now, some fields contain spaces and that require a lot of post-processing cleanup and slows down the generation of reports.
What is affected and maintained by Analytics
- udp-filter already has support for the tab character
- webstatscollector: we compiled a new version of filter to add support
for the tab character
- wikistats: we will fix the scripts on an ongoing basis.
- udp2log: we have a patch ready for inserting sequence numbers separated
by tab.
In particular, I would like to have feedback to three questions:
Are there important reasons not to use tab as field delimiter?
Are there important pieces of logging that expect a space instead of a
tab and that need to be fixed and that I did not mention in this email?
- Is February 1st a good date to deploy this change? (Assuming that all
preps are finished)
Best,
Diederik
