FlorianPribahsniIs it possible to rename a user? for example FlorianPribahsnik to FlorianEichinger [09:03]
pharveyFlorianPribahsni: sadly this isn't a fun thing to do with the default user mapper. See http://foswiki.org/Extensions/TopicUserMappingContrib which talks about deleting a user.
Essentially you can just rename the user's topic, but then you'll have to find their .htpasswd entry, rename the user part in that field and then reset their password
[09:17]

FlorianPribahsniIf I rename the topic an change the name in htpasswd file the user can sign in with his new name? [09:25]
CDotFlorianPribahsni: yes; though that won't affect the signature on existing topics.
so you are, in effect, rewriting history

packoman_Hi. I have a question regarding the include{...} macro
suppose that I attach a homepage to a topic and use %include% to put it into the topic.
Will I be able to add section definitions such as %STARTSECTION{"name"}% and %ENDSECTION{"name"}% to that HTML code and have foswiki filter the HTML code?
that would be very cool cause then I could have better controll over what to include from HTML files I get from MATLAB

gac410$createdate and $date - I'll bet they either dip into RCS or file system stats vs. the UserList which only uses formfields [14:24]
Babarwce :) [14:25]
gac410So was this horribly slow before fcgi and we just didn't notice? Or is forking to rcs on fcgi that much worse.
Sounds like the MongoDB work would help this out.
[14:26]
Babarwe're forking to rcs? We could try to use RcsLite :)
and it's easy to try with the old config if you want
[14:27]
gac410Hm - or at least pull timing on trunk.foswiki.org
Yeah store has changed but it will give us an idea.
[14:28]
Babarhum, trunk doesn't have the users
so you can't try it out there
[14:28]
gac410oh foo.
ln -s Main FOMain ?
[14:29]
Yeah definitely $createdate - query works fine if I remove it from the results. [14:35]
It causes Meta to getRev1Info, which loads a temporary copy of the topic, with rev=1. Smell in the code says: this is a horrid little legacy of the InfoCache object, and should be done away with [14:43]
..... (idle for 20mn)
SvenDowideityes, its plausible that forking with fcgi would cause pain
tbh, the sotre2 work might help there even more than mongo
but we'll have to see about how much cross request caching i can get done
I'd like the backend (non-acl/user) portion of the store to persist much longer
SvenDowideit goes back to burning sketti
[15:03]
gac410so you would recommend switching to rcs-lite on f.o? And pure-perl search?
Or should we build the nativeSearch contrib?
[15:04]
Babargac410: stop playing with f.o. You're stressing the machine, and I'm getting emails every minute :p [15:10]
gac410I'm not doing anything on f.o
other than sitting idle logged in
logged out now
[15:10]
Babarok, then I'm guessing we have a few web crawler visiting again [15:13]
gac410Last thing I did on f.o was around an hour ago I did a find | wc to count the number of files in Main [15:13]

[15:23]
gac410Babar, how do we turn fcgi on/off - Is it an apache start parameter or ?? [15:28]
SvenDowideitwell, first q i have, is... whats the difference in number of biggest thing that i've had with using fcgi, is that the crawlers hit more often, because things reply faster [15:28]
Babarjust comment the module line in httpd.conf [15:28]
SvenDowideitand because there are some cpu bits removed by the persistence, the disks/io become more of a bottleneck
when taht happens of course, swtiching to cgi only makes it workse
[15:29]
gac410Yeah - the tuning water balloon - squeeze out some performance in one place and bottleneck develops elsewhere. [15:30]
SvenDowideity
the other thing that hurts, is when you have your settings very different
ie, a different number of fcgi backend processes compared to the number of cgi processes allowed
[15:30]
gac410So any search using $createdate is bad. What we don't know is, is it worse or just becoming noticable because of cgi timeouts.
fcgi backend set to 50. spot checking I have not seen more than 8 or 9. CGI seemed to be similar from ps spot checks iirc.
maybe more cgi - nothing precise - just recalling what ps looked like when greping for http
[15:31]
SvenDowideitcreatedate does mean a big horrid rlog hit [15:34]
gac410right now for instance, 12 httpd tasks, 6 fcgi backends. [15:34]
SvenDowideitso i would start with rcslite
y
[15:34]
***ArthurClemens has quit IRC (Quit: Leaving...) [15:34]
SvenDowideitand thats compared to how many cgi backends in non fcgi? [15:34]
gac410didn't change that - only added fcgi with max of 50. [15:34]
SvenDowideity, but you need to know what that was set to [15:35]
***Lynnwood_ has joined #foswiki [15:35]

[15:35]
SvenDowideitwhat i've kind of noticed before, is taht the startup delay that non-persistent perl has diue to loading a fresh process
seems to give other requests time to run
whereas fcgi etc can sometimes hit harder sooner
still, try rsclite
[15:36]
gac410I don't see where cgi backends is set - [15:37]
SvenDowideity, i'd have to look it up - not even sure what to do atm
they didn't nap today, so they're havocking atm
[15:37]
***Lynnwood has quit IRC (Ping timeout: 256 seconds)

[15:37]
gac410are there risks of topic corruptions with rcslite - I seem to recall some irc anecdotes about issues [15:38]
SvenDowideitinstead of napping, they decided to go for another ride on their walking bikes [15:38]
gac410er... not with - but with switching between rcs & rcslite [15:38]
SvenDowideitthere is a risk of corruption with rcswrap too
but i'll not add more irc anecdotes :)
[15:38]
gac410Babar - any objection to my switching f.o to rcslite now? [15:48]
Babarnon [15:49]
gac410update config and reload apache to refresh the fcgi tasks
Wohoo ... that fixed UserListByDateJoined !
[15:49]
***MartinRowe has quit IRC (Quit: Leaving.) [15:57]
SvenDowideitgac410: [15:57]
gac410yes [15:57]
SvenDowideitplease, write up what you've found
and write a blog post on it
especially numbers and common symptoms
[15:57]
gac410yes - though not sure how to do a blog post. [15:58]
SvenDowideiteven if you have to re-create it by making f.o perform badly
write it up anywhere you like (i'd use a secured topic on f.o) and mmm, talk to micha
i think he should have keys to the blog site
i probly do, but i can't recal much :/
[15:58]
gac410well - the numbers are easy because we don't know how bad it can be. I didn't find a fcgi timeout that let the UserListByDateJoined actually complete. [15:59]
SvenDowideitbought the girls walker-bikes today
but you do havea max bound
[15:59]
gac410yes. [16:00]
SvenDowideitand you can hit the working one and a cgi one [16:00]
gac4103 minutes for a user list of 2900 users or thereabouts. [16:00]
SvenDowideiti generally leave a url path to get to the cgi scripts
so that i can compare to what is running
[16:00]
gac410hm - don't have that. :-( [16:01]
SvenDowideitrather than turning them on & off, i just change the default paths for apache [16:01]
gac410PersonalInfoFaceBook now loads as well - though not sure why that one is affected. Hm. So how about search Forking vs Native vs PurePerl ? [16:06]

and now?
[19:30]
gac410trying - did you reload apache?
After any config change either kill the fcgid tasks or do a reload. don't have to restartl
same error
still same, and nothing logged to error_log :-(
It was timing out at 180 seconds before we switched to rcs lite
Arthur added a verbatim tag to turn it off because bots were hitting it multiple times. Just took it out to see if it works better with rcslite
[19:30]
***ArthurClemen has joined #foswiki [19:40]

***FiberOptix has joined #foswiki [23:21]
FiberOptixSo, I was following the "quick upgrade" instructions to copy over an existing foswiki installation and sure enough, it broke my foswiki. [23:22]
gac410Upgrading from ... to ... ?? [23:22]
FiberOptixI believe it was 1.1.2 to 1.3.0 [23:23]
gac4101.1.2 to 1.1.3 hopefully we don't have a 1.3 :-)
What has broken?
[23:23]
FiberOptixSorry, yes you're right
Anyway, things went from bad to worse and now I've got to install 1.3
[23:24]
gac4101.1.2 to 1.1.3 is a minor upgrade - Unless debian, you shuould be able to un-tar / un-zip the upgrade file over the top of the install.
er - or Windows - that can be tricky as well.
okay so what has gone wrong - what did you do. Hopefully you have a backup?
[23:25]
FiberOptixYes, I'm on windows.
unfortunately
[23:26]
gac410Ah ... okay. Did you originally use the windows "installer" or did you use the zipfiles? [23:27]
FiberOptixIs there a windows "installer" for 1.1.3? I used a zipfile [23:27]
gac410The big thing after applying the zipfile is to cd to bin, and then run ../tools/rewrite-shebang to fix up the perl #! line in each bin file.
no - no installer for 1.1.3 I don't think. But if you originally used the installer, you didn't have to do the shebang stuff.
Are you using apache? or iis?
[23:28]
FiberOptixI used it when I installed 1.1.2 [23:29]
gac410okay - so the installer updates the bin files to have the correct perl location. When you unzip the normal distribution you lose that information. But rewrite-shebang tool will fix them up.
I think for windows, you cd to bin. and then issue perl -I ..\lib ..\tools\rewrite-shebang.pl ... or something like that.
[23:30]
FiberOptixI'm nolonger trying to upgrade. I'm trying to do a fresh install
ok
[23:31]
gac410So even a fresh install of the tarfile / zipfile. You need to do the rewriteshebang step. [23:32]
FiberOptixYes, doing that now
Ok, done
Can you remind me how to get apache to correctly point to the foswiki installation? At the moment I'm getting a 404 when trying to access foswiki/bin/view in my browser
[23:32]
gac410That *should* let the scripts run. Then point apache at bin/configure [23:34]
FiberOptixhow please [23:34]
gac410Ug - I think somewhere in program files/apache/... will be the httpd.conf which will INCLUDE the foswiki.conf.
It's been a really long time since I touched foswiki on windows. I need to reboot my vm
[23:35]
FiberOptixI don't see any includes for foswiki.conf [23:36]
gac410I generated my foswiki.conf using Foswiki:Support/ApacheConfigGenerator [23:37]
FoswikiBothttp://foswiki.org/Support/ApacheConfigGenerator [ ApacheConfigGenerator ] [23:38]
gac410then put that file in c:\progam files\Apache Software Foundation\Apache 2.2\conf\foswiki.conf
and add "include foswiki.conf" to the httpd.conf in that directory
er... Include conf/foswiki.conf
[23:38]
FiberOptixOk [23:39]
gac410You don't have any of your original configuration? [23:40]
FiberOptixUnfortunately, no [23:46]
gac410Well ApacheConfigGenerator should build you a good one. So that's the best way to go. [23:47]
FiberOptixOk, thanks
I really shouldn't have even bothered with the upgrade
[23:47]
gac410I'd like to understand what went wrong - it really should have been relatively straight forward. [23:48]
FiberOptixWell after I copied the files over, trying to access bin/view gave an 'internal server error'
guess I also needed to run the rewrite-shebang
does it matter if my "include foswiki.conf" goes at the bottom of httpd.conf?
oh shoot, now Apache fails to start
weird. When I add include foswiki.conf apache fails to start
