00:37 Waylon joined #koha
00:37 Waylon hiya all!
00:38 Waylon koha 3.0presomething. How easy is it going to be to speed things up slightly, using memcached?
00:38 Waylon And what about nginx? how do I use that with koha
00:38 Waylon ?
00:39 eythian 3.6 supports memcached fairly easily I think. I doubt 3.0 does.
00:39 Waylon during a siege using 15 concurrent, im getting returns of up to 16 seconds... thats.. bad.
00:39 druthb joined #koha
00:39 eythian I don't think you'd get much gain from nginx (though you might.) It'd still be a CGI app though.
00:40 druthb o/
00:40 eythian Waylon: but a slow query watcher on your database, maybe you've got something that's taking too long there, or IO troubles.
00:40 eythian *put
00:40 eythian perhaps a missing index somewhere.
00:40 Waylon so, if i want speed, im going to have to upgrade koha?
00:40 eythian it'd be the easiest way, yes.
00:41 Waylon Longest transaction:       17.45
00:41 eythian You could always backport the memcached etc. patches, but it'd be a fair bit of work.
00:41 Waylon Response time:        6.38 secs
00:41 eythian My money is on it spending that time in the database.
00:41 Waylon right
00:42 eythian I think the option you should turn on is slow-query-log, or something similr
00:42 Waylon right
00:42 eythian it'll make mysql dump out anything that takes longer than /n/ seconds
00:42 eythian (or ms perhaps)
00:42 eythian which helps figuring out where problems are.
00:43 rangi thats 3.0 pre .. 3.0.0 was releases 10 aug 2008 ... so its even older than that so trying to backport to that will be a world of pain
00:44 Waylon yeah. hell.. i tried doing a git review on this install.. i couldn't find a version match. its a mismash of pre and manually applied patches that I can't figure out, and the arabic mods.
00:45 Waylon so... yeah.. backporting memcached patches... not going to happen.
00:47 eythian I'd recommend upgrading, but in the short term check out your database.
00:48 Waylon and getting nginx to replace apache, not going to be easy either?
00:48 eythian Probably easier, but apache isn't adding 16 seconds of delay to your requests.
00:50 eythian (unless something else is, and your apache maxchilds is set low)
01:04 Waylon hmm.. slow queries are inserts into sessions, and a borrower_attribute increment due to login (tracking times logged in for that user, only done while logging in) both of them are query time 2. but once the first query is done by siege.. there isn't any more slow queries.
01:04 Waylon yet the siege time still increaes.
01:06 Waylon this server runs on a virtual machine, how much memory should i allow for each apache child in calculations?
01:06 Waylon xen vm that is.
01:06 Waylon not a first gen virtualbox.
01:20 Waylon okay.. my apache is prefork type.
01:20 Waylon StartServers          5
01:20 Waylon MinSpareServers       5
01:20 Waylon MaxSpareServers      10
01:20 Waylon MaxClients          150
01:20 Waylon MaxRequestsPerChild   0
01:34 sdaugherty left #koha
01:42 druthb how big is count(*) from sessions?
01:43 druthb Waylon:  ^^   I've found that cleaning up the clutter there helps.
01:45 jcamins_away Yikes! Pre-3.0?
01:46 Waylon 3.0.0.pre2 i think it started out as.
01:46 Waylon yea
01:46 jcamins_away Better you than me!
01:46 jcamins_away Waylon: I have no useful advice to offer, but I'd agree with druthb that your sessions table should be cleaned.
01:47 jcamins_away And with eythian that you should figure out a way to upgrade.
01:47 Waylon eventually ill get it upgraded, and be developing with you guys.. until then... this job is mostly sysadmin and coding additions.
01:48 Waylon 1035 sessions.. yeah....
01:49 druthb well, that's not the issue--the times I've seen it being a problem, it had tens of thousands of entries.
01:53 Waylon its only 15 concurrent users for the siege.. i don't get why the response time increases.
01:55 Waylon ah.. adding a branch limit on the zebra query, adds a second.
01:57 Waylon but, a search that results in a precise match redirect, with only basic kw search... took 11 seconds to redirect.
01:58 Waylon maybe i need to tune zebra?
02:02 eythian do you know that zebra is the issue?
02:02 eythian if not, you can't begin to tune it
02:11 Waylon mysqld is at the top of the top list..
02:11 jcamins_away Waylon: I would be shocked if it were Zebra.
02:11 * Waylon nods.
02:11 jcamins_away Waylon: in fact, if it were Zebra, I'd be so shocked that I might fall over.
02:11 jcamins_away ;)
02:12 Waylon it may be archiac and mysterious, difficult to work with, but it was coded well?
02:12 jcamins_away Waylon: I don't know about "coded well," but it's pretty fast.
02:14 eythian when it works, it works really quite well. When it breaks it gets mysterious.
02:14 * Waylon nods.
02:14 eythian I think this is due in no small part to me not really understanding how it works inside.
02:14 Waylon cryptic messages like error: 114
02:15 eythian yeah
02:15 Waylon looks like mysql might need optimizing.
02:16 eythian there also have been speed improvements in newer Koha versions...just sayin' :)
02:16 Waylon yeah.

05:07 cait hi eythian :)
05:11 huginn` New commit(s) needsignoff: [Bug 5473] 952 fields should be filled in by Acquisitions <[…]w_bug.cgi?id=5473>
05:15 cait eythian: what are you working on that late?
05:15 eythian it's not late, it's still sunny outside.
05:15 eythian I'm making the returns process be not dependent on barcodes.
05:15 eythian i.e, you can do a return using an item number.
05:16 eythian however, a lot of the code around there is Old Code that treats barcode like a primary key, so I'm having to refactor a whole lot.
05:17 eythian the next step for this would be allowing searching for titles on the circ screen to issue/return things.
05:17 eythian (for a new client we have who doesn't tend to use barcodes so much)
05:21 cait ah
05:22 cait well good luck :)
05:22 eythian yeah, ta :)

06:02 eythian heh good.
06:03 Waylon waylon?
06:03 wahanui i heard waylon was having some connection troubles.
06:04 Waylon wahanui, Waylon is the 33rd contributor to Koha. Currently works for
06:05 wahanui ...but waylon is having some connection troubles....
06:05 Waylon hrm.. damn.
06:05 mib_41oce5 Hello
06:05 eythian no wahanui, Waylon is the 33rd contributor to Koha. Currently works for
06:05 wahanui okay, eythian.
06:06 Waylon hello mib_41oce5 !
06:06 mib_41oce5 I am new to Koha
06:06 mib_41oce5 one basic question: is Koha and LibLime koha different?
06:06 eythian mib_41oce5: yep
06:07 Waylon welcome! Yes, sadly, Koha and Liblime broke company some time ago... Liblime has a fork off of old code... and has extensively customised it.
06:07 mib_41oce5 ok, damn, two days wasted
06:07 mib_41oce5 I installed debain in my Mac using Virtual Box
06:08 Waylon Hmm? at least you haven't invested money into a liblime solution.
06:08 mib_41oce5 and simply searched google for Koha and ended up installing liblime koha
06:08 Waylon ooo.
06:08 eythian sounds unpleasant
06:08 Waylon how did that happen?
06:08 mib_41oce5 but now when I researched more
06:08 Waylon so.. the first result that comes up is liblime koha?
06:08 mib_41oce5 yes
06:09 mib_41oce5 i ended up installing from version 4.08 from liblime but it's not working
06:09 Waylon yeah... we can't help you with liblime.
06:10 Waylon at least i can't.
06:10 mib_41oce5 have to uninstall and install 3.4 from koha
06:10 mib_41oce5 yes, I understand
06:10 eythian[…]on_Debian_Squeeze <-- mib_41oce5, perhaps start here
06:10 eythian 3.6 is the current version that you want.
06:10 * Waylon nods. "For maximum support from this channel, yes.
06:10 Waylon 3.6...
06:10 mib_41oce5 Thanks for the link
06:10 mib_41oce5 oh 3.6
06:10 Waylon man, im way behind on mandumah.
06:11 Waylon prehistorically behind.
06:11 eythian that's what we keep telling you ;)
06:11 mib_41oce5 ok great thanks
06:11 mib_41oce5 will have a got at it today
06:12 kf joined #koha
06:12 kf hi #koha
06:12 Waylon yeah. gotta recode all this stuff into a module that i can patch in and out without too much trouble though. And teach the designer how to use koha's translation system, and css customization to move things around.
06:14 Waylon so yeah.. alot of work to upgrade.
06:14 eythian yeah. The best way to deal with that really is just to keep on top of it all.
06:16 * Waylon nods. "And then you got the os security updates, vunerablility reports, optimization, drupal security updates... properly on top of, its a fulltime job?"
06:16 * Waylon is the sole admin of and is feeling slightly bewildered by how much there is to do.
06:17 eythian clearly you just need to automate things ;)
06:18 Waylon how do you automate without the risk of breaking something?
06:18 eythian you have a test server you roll out to first.
06:20 * Waylon nods, "I have one of those. my 2 bare metal xen servers, have 1 live server and 1 non-public server, one will be used for dev,. the other for all updates.
06:20 * eythian needs to develop some Puppet modules for Koha
06:20 Waylon hmm? Puppet?
06:21 eythian puppet makes automating server configs easier.
06:23 Waylon ah.
06:25 Waylon I think ill do rsync from the update server to the 2 live servers, of koha code and the various configs that need to be changed. (apache, bind), and the actual data archive.
06:28 eythian[…]aming_handout.pdf <-- also read my KohaCon slides if you need more incentive ;)
06:28 Waylon yeah.. incentives are good.
06:29 Waylon wha? a arabic crowd?
06:29 Waylon where was this?
06:30 eythian I was doing a workshop thing in Malaysia, that's where that photo is from.
06:30 Waylon ah wow cool.
06:31 Waylon yeah.. i suppose, properly coded, my database within a database idea might be useful.
06:31 eythian every problem can be solved just by adding another layer of abstraction, after all...
06:32 Waylon that is, mandumah is seperated into three segments, currently. but all in the same mysql/zebra ... just abusing the branch table and marc tags.
06:33 Waylon cause.. we don't have branches.
06:33 mib_41oce5 left #koha
06:33 eythian wouldn't it be easier just to pretend they're branches?
06:33 syed left #koha
06:34 Waylon yeah. thats what i do. for each biblio... those segments that have that biblio in them, have a item in the biblio.
06:34 Waylon ... that changes in 3.6 though, right?
06:34 Waylon zebra doesn't include items anymore?
06:34 eythian zebra does, just the database doesn't
06:35 eythian basically, 952 doesn't exist and is generated when needed.
06:35 eythian (which includes sending to zebra)
06:35 Waylon ah... hrm... so.. how would my system be ported then?
06:35 eythian no reason you couldn't do it the same way.
06:36 eythian you just might query differently inside Koha.
06:37 eythian although my recommendation would be to rebuild it, and make it an option inside Koha so that you can make it public and not worry about it in the future :)
06:37 eythian wholly chao, my code works.
06:37 Waylon yeah. ill probably make an actual table with actual custom marc tags.
06:37 Waylon i think...
06:38 Waylon eh.. im not sure.
06:38 julian_m joined #koha
06:38 eythian I'm going to leave it there and go away and hopefully it'll still be working tomorrow.
06:39 eythian well, there is the extended marc thing still there.
06:39 Waylon eythian?
06:39 wahanui eythian is probably in NZ. ;) or a good influence
06:39 Waylon what, thats all thats said? hrm.
06:39 Waylon robin?
06:39 wahanui robin is probably on annual leave
06:39 eythian but, it does seem like you're just making more pain for yourself.
06:39 Waylon Yeah. well.. its what the boss wants.
06:40 eythian sure, but you could do it in a more portable fashion and ultimately not worry about it.
06:40 Waylon hmm, any advice?
06:41 eythian Not really. I'd write up what you need it to do and start a mailing list discussion. I don't really have enough information to be constructive.
06:41 * Waylon nods.
06:42 eythian later, y'all
06:42 Waylon And the authentication by ip , iprange and virtualhost, may be useful to others too.
06:42 eythian definitely.
06:42 eythian we're always adding new mad authentication schemes
06:42 Waylon and referer url
06:43 Waylon so.. currently, virtualhost + referer url  or ip address + virtualhost = pass.
06:43 Waylon on top of standard username/password.

08:45 kf and hi reiveune
08:45 * Waylon has been abusing the branch system to create divisions within the same database into different sections of the database.
08:45 Waylon so a user that had access to A branch and B branch could only search A or B or both branches.
08:45 Waylon not C branch.

09:14 francharb joined #koha
09:15 francharb hi
09:15 wahanui salut, francharb
09:30 mbalmer so, if instead of writing all of SQL directly in the code, some of it is generated using a Perl module, that Perl module can produce optimal, database dependant SQL, e.g.:
09:30 mbalmer $sql = "select * from table where " . datediff(now, then);
09:31 AmitG heya francharb
09:31 wahanui francharb falls asleep easily at sea.  Don't believe me?  Just ask Brooke.
09:31 mbalmer so datediff produces the right SQL code for mysql or pgsql, depending on which db is being used.
09:31 mbalmer this technique could be used for low-level stuff, but also for high level operations:
09:32 mbalmer $sql = sort_all_books;
09:40 mbalmer I suggest two different modules for this:  SQL for the lower-level SQL formatting, with functions like SQL::today, and DB for higher level procedures, which may boild down to many lines of perl code in the Mysql case while simply calling a stored procedure in the PostgreSQL case.

15:59 Amitg Hi indra
16:12 sekjal does anyone have an opinion on the usage of $dbh->last_insert_id()?  it's used very rarely in Koha, and I'm wondering if there is a particular reason
16:12 jcamins_away sekjal: it's not thread-safe.
16:13 jcamins_away sekjal: unless it's implemented in a different way in Perl/DBI than it is in libmysql.
16:13 sekjal I could see there being a race condition... if another INSERT happens before the function is called, you'd get the wrong ID
16:13 jcamins_away Right.
16:14 indradg left #koha
16:14 sekjal wondering how likely that actually is
16:14 hdl last_insert_id can be and should be retricted to table.
16:14 jcamins_away hdl: still not thread-safe.
16:14 hdl jcamins_away: yep.
16:14 jcamins_away sekjal: in my experience using C (granted, that was pretty high-performance), very.
16:14 hdl But no other way to get the latest id in table.
16:15 jcamins_away hdl: yes, and it's a problem, but that's probably why Koha doesn't use it.
16:15 sekjal suppose I could do a query looking for a row that matches all the field values I just put in...
16:15 mbalmer with postgres you can use a serial, maybe mysql has sth similar.
16:15 hdl otherwise, we should do a select on the table... which imho is quite... awkward too.
16:15 sekjal that seems so inelegant, though
16:16 sekjal what I'm looking to do:  alter EnqueueLetter to return the message_id of the newly added message, instead of just "true"
16:17 mbalmer check if mysql does have the equivalent of PostgreSQL serials, then it is easy.
16:17 jcamins_away mbalmer: if Koha used transactions, it'd be easy.
16:17 mbalmer not using transactions is a crime anyways.  but that is a different story.
16:17 jcamins_away Unfortunately, I'm pretty sure Koha uses autocommit=1.
16:18 mbalmer the whole SQL underpinnings seem a bit, well, questionable.  but of course that leaves room for improvement.
16:18 mbalmer ;)
16:18 mbalmer and that means fun.
16:19 hdl mbalmer: so many ways to make improvements :D
16:19 mbalmer yeah ;)
16:20 mbalmer I just hope I get a few customers that use it, so I can justify putting some effort in to the code.
16:24 sekjal hmmm... I can't assume that the information INSERT'ed in EnqueueLetter is unique... it would be safe to do so with the timestamp, but that's using MySQL's NOW()
16:24 huginn New commit(s) needsignoff: [Bug 6323] Attach/move items -- error handling cleanup <[…]w_bug.cgi?id=6323>
16:25 sekjal but if I order by the timestamp desc, and limit to 1, that should reduce the odds fetching the wrong info to virtually nil

16:27 Amitg Hi sekjal
16:27 sekjal hi, Amitg
16:27 mbalmer sekjal, no hacks, do it right ;)
16:28 mbalmer MySQL _has_ the SERIAL data type.  so use it.
16:29 sekjal mbalmer:  are you proposing I change the Koha data structure for my project?
16:29 mbalmer 1) $id = next serial value
16:29 mbalmer 2) insert into … (id, …) values ($id, ...)
16:29 mbalmer 3) return $id
16:30 sekjal mbalmer: so the 'next serial value' command reserves the ID?
16:30 Amitg left #koha
16:31 matts is now known as matts_away
16:31 maximep i don't get at all the difference with last_insert_id and getting the next id
16:31 mbalmer in postgresql you use 'nextval(serial_name)', there exists a similar idiom in MySQL
16:32 mbalmer maximep, getting the id from a serial upfront is safe, thread safe as well.
16:32 sekjal mbalmer:  does nextval(serial_name) reserve that new id?  so no other process could slip in and claim it in the interim?
16:32 mbalmer beacuse each values is guaranteed to be produced only once
16:32 trea-phone is now known as trea
16:33 mbalmer sekjal, exactly, that is what serials are for.
16:33 maximep i dont understand that serials stuff... the mysql doc says it's just a good old auto_increment unique
16:33 hdl sekjal: I would not take  it  for granted it works same as postgresql. That Would need some test...
16:33 mbalmer it's for sure worth the time to read the docs about them
16:33 mbalmer hdl, ack.
16:34 mbalmer mysql is such a POS that I would also test it before using it ;)
16:34 sekjal mbalmer:  making that kind of change to the Koha datastructure is outside my specification
16:34 sekjal I'll have to find an alternate route
16:34 mbalmer like non working, not safe code?
16:34 mbalmer ;)
16:35 maximep i dont understand how last_insert_id is not threadsafe. It returns the last insert from that particular connection, doesn't it ?
16:35 mbalmer what if, in the meantime, someone else inserted sth?
16:36 maximep someone else will be on a new connection to the db
16:36 hdl maximep: should be... But if you are using persistent connection, then you may have some strange behaviour.
16:38 maximep hmmm, pretty sure cgi scripts will always create a new connection
16:38 mbalmer well, if you use MySQL you probably don't care to much about your data anyways, so the implementation details don't matter either ;P
16:38 sekjal[…]rk%3F%3F_P171325/
16:39 maximep threadsafe from the same sth
16:40 sekjal ok, so by that logic, modifying EnqueueLetter should be okay.  dbh is created, sth is set and executed, then subroutine ends
16:40 mbalmer using stuff like last insert ids only creates non-portable code.  creating a new unique id upfront, and using it in the next insert can be made portable.
16:41 maximep i just dont understand how you can create a new id upfront
16:41 maximep never seen anyone do that in myusql
16:41 mbalmer by using a monotonically increasing number.
16:42 sekjal mbalmer:  if you file a sub-bug to your "Koha uses MySQL" omnibus, detailing the methodology required for this, we can work on implementing it for Koha 4.0
16:43 sekjal until then, I'm going to stick with last_insert_id(), as it's safe in this specific instance, and does have precedent elsewhere in the codebase
16:43 mbalmer no two callers can get same number if you use the right mechanism.
16:43 mbalmer yeah, repeating errors makes it correct use ;)
16:44 mbalmer but go on, really, it is easy enough to fix later.
16:44 sekjal mbalmer:  I'll happy to fix it in both my instance, and the legacy ones, at such time as there is a basis for it
16:45 mbalmer as I said before, personally I think that code should be correct.  But then maybe that is because I come from a different corner ;)
16:45 mbalmer (development wise, that is)

16:47 maximep because i know it's way more powerful than mysql. someday :/
16:47 mbalmer maximep, only partly true (the snobcorner), it's actually worse ;)
16:48 mbalmer with the introduction of a shim layer, I think that both mysql and pgsql can be used.

21:13 sekjal cait:  you were mentioning something about a timestamp on the borrowers table earlier today
21:13 cait ype
21:13 cait yes
21:13 cait something like a last update date
21:13 sekjal I was thinking, it would be handy to have timestamps for emails, addresses and phone numbers, for "date last verified"
21:14 cait I am not sure if this isn't overcomplicating things
21:14 sekjal I"m sure it is
21:14 cait you can get the update information from action_logs I think
21:14 sekjal the library I was training last week was very information in a verification method for emails, because they don't trust the data they have
21:14 cait it's only a bit hard to get out and a timestamp would also show the date when a borrower was created or transferred - a bit faster than querying action_logs
21:17 cait transferred to deletedborrowers
