Question

Hello,

I encountered a problem regarding the webstatistics topic. Although the log-Files exist and do contain the correct information, topic views do not get updated in webstatistics topic. (Whereas topic saves do) In Twiki.cfg doLogTopicView is set to 1. When I set doDebugStatistics to 1, debug.txt contains many entries of the form:

07 Jan 2005 - 10:42 Invalid log file line = '| 07 Jan 2005 - 08:39 | Berlin.Gast | view | Berlin.WebHome |  | 213.69.239.40 |'
07 Jan 2005 - 10:42 userName = ''
07 Jan 2005 - 10:42 opName = ''
07 Jan 2005 - 10:42 webName = ''

This problem occurs regardless of the method I employ to generate the statistics (via cron job or manually or by executing the statistics script in the shell). I do not know whether this has anything to do with the problem, but testenv shows one strange problem:

User:    twiki
   Note: Your CGI scripts are executing as this user.
   Warning: Since your CGI script is not running as user nobody, you need to change the locks in the *,v RCS files 
of the TWiki distribution from nobody to twiki. Otherwise, changes to topics will not be logged by RCS.
   Fix: If needed, relock all the rcs files to user twiki

Though I already executed the fix and all files are most likely correctly locked, this message remains on the testenv screen. (see attached testenv.htm)

Do you have any ideas what to do about that?

Not sure what's going on here - you will probably need to do your own TWikiDebugging... The statistics script should be able to handle non-WikiWord topic names OK, but the invalid format error messages are a concern - have a look in the code for SVNget:lib/TWiki/UI/Statistics.pm where it prints the message, and maybe print the regexes imported from $TWiki::... to check they are set to something.

You may find that use re 'debug'; is useful to provide debugging info on the regexes.

When I tried to print out $1, $2 and $3, respectively $userName, $opName and $webName, I discovered that they were all empty in _collectLogData in Statistics.pm, line 253. When debugging the regexes, I get

webNameRegex: (?-xism:[[:upper:]]+[[:alpha:][:digit:]]*)
userRegex: (?-xism:(?:(?-xism:[a-z0-9]+)|(?-xism:[[:upper:]]+[[:lower:]]+[[:upper:]]+[[:alpha:][:digit:]]*)))
opRegex: (?-xism:[a-z0-9]+)

Looks alright, doesn't it?

Is it possible that Twiki has a problem with the user name since it contains only one uppercase letter?

-- JanHegewald - 14 Jan 2005

Well - I found the problem. It really was the user name. I changed $defaultUserName in TWiki.cfg from "guest" to "Gast" (German for guest).

Obviously the former produced user entries like Main.TWikiGuest (according to the sample lines in Statistics.pm) whereas the latter simply produced an entry like Main.Gast which misses a second uppercase letter.

So setting $defaultUserName to "TWikiGast" solved the problem.

Thanks for reporting how you solved this - glad it's working!
