Note that if page produced some data and then timed out - which is
possible for Blazegraph queries - then by the time the error happens
part of the response has been sent already, so there's no way to set
error http code etc. Thus such responses are not distinguishable from
valid replies, at least not without looking into the content.

  As the etag is based on mtime, if mtime are different, etags are different. 
etags don't care about small difference, they are either the same or not. I'm 
not clear on how trebuchet works and if we could ensure that mtimes are

  Yes. Otherwise the varnishes have no idea that it changed after a deployment.
  
  Note that requests with If-Modified-Since and the If-None-Match are nor 
answered from the varnish by consulting the cache for the corresponding normal

Yurik added a comment.


  merged, please take a look at 
https://commons.wikimedia.org/wiki/Commons:Village_pump/Proposals#Tabular_data_storage_for_Commons.21
  
  @matmarex , JsonConfig is an extension I built a while ago for storing 
structured data on wiki and making it available from another wiki. Basically it 
was a refactoring of my Zero code, to allow this functionality to be shared. It 
was already used for data namespace for storing JSON (for a limited 
deployment), but I decided to make some more improvements before promoting it 
for a wider audience. JsonConfig is a misnomer - because it was initially 
thought to be for configurations rather any data, even though the code is 
actually identical.  We could of course rename it, but I don't think it is 
worth the hassle.

[Wikidata] SQID: the new "Wikidata classes and properties browser"

2016-04-19 Thread Markus Kroetzsch

Hi all,

As promised a while ago, we have reworked our "Wikidata Classes and 
Properties" browser. I am happy to introduce the first beta version of a 
new app, called SQID:


http://tools.wmflabs.org/sqid/

It is a complete rewrite of the earlier application. Much faster, more 
usable, much more up-to-date information, supported on all reasonable 
browsers, and with tons of new features. Try it yourself, or read on for 
the main functions and current dev plans:



== Browse classes and properties ==

You can use it to find properties and class items by all kinds of 
filtering settings:


http://tools.wmflabs.org/sqid/#/browse?type=properties
http://tools.wmflabs.org/sqid/#/browse?type=classes

New features:
* Sort results by a criterion of choice
* Powerful, easy-to-use filtering interface
* Search properties by label, datatype, qualifiers used, or co-occurring 
properties
* Search classes by label, (indirect) superclass or by properties used 
on instances of the class

* All property statistics and some class statistics are updated every hour

== View Wikidata entities ==

The goal was to have a page for every property and every class, but we 
ended up having a generic data browser that can show all (live) data + 
some additional data for classes and properties (this is our main goal, 
but the other data is often helpful to understand the context). The UI 
is modelled after Reasonator as the quasi-standard of how Wikidata 
should look, but if you look beyond the surface you can see many 
differences in what SQID will (or will not) display.


Examples:
* Dresden, a plain item with a lot of data:
  http://tools.wmflabs.org/sqid/#/view?id=Q1731
* Volcano, a class with many subclasses:
  http://tools.wmflabs.org/sqid/#/view?id=Q8072
* sex or gender, a frequently used property:
  http://tools.wmflabs.org/sqid/#/view?id=P21

Notable features:
* Fast display
* All statement data with all qualifiers shown
* Extra statistical and live query data embedded

== General Wikidata statistics ==

As a minor feature, we also publish statistics on the weekly full 
Wikidata dump (which we process to get some of the statistics):


http://tools.wmflabs.org/sqid/#/status

Don't trust the main page -- find out how many entities there really are ;-)


== Plans, todos, feedback, contributions ==

We are on github, so please make feature requests and bug reports there:

https://github.com/Wikidata/WikidataClassBrowser/issues

Pull requests are welcome too.

Known limitations of the current version:

* Data update still a bit shaky. We refresh most statistical data every 
hour (entity data is live anyway), but you may not see this unless you 
clear your browser cache. This will be easier in the future.

* Entity data browser does not show sitelinks and references yet.
* Incoming properties not shown yet on entity pages
* I18N not complete yet (if you would like to try the current dev 
status, see, e.g.: http://tools.wmflabs.org/sqid/#/view?id=Q318=de)


Moreover, we are also planning to integrate more data displays, better 
live statistics, and editing capabilities. Developers who want to help 
there are welcome. SQID can also be a platform for other data display 
ideas (it's built using AngularJS, so integration is easy).


== And what about Miga? ==

The old Miga-based app at 
http://tools.wmflabs.org/wikidata-exports/miga/ will be retired in due 
course. Please update your links.


== Credits ==

I have had important development support from Markus Damm, Michael 
Günther and Georg Wild. We are funded by the German Research Foundation 
DFG. All of us are at TU Dresden. Complex statistics are computed with 
Wikidata Toolkit. Live query results come from the Wikidata SPARQL Query 
Service.


Enjoy,

Markus

thiemowmde added projects: Patch-For-Review, Wikibase-DataModel-Services.
thiemowmde added a comment.
Herald added a subscriber: TerraCodes.


  In February 2015 I created a "GenericEntityDiffer" that uses feature 
detection to create diffs from any entity type (even between different entity 
types).
  
  This was not meant to patch and store patched entities. It can't because it 
will miss and skip all entity features it does not know about. This was meant 
to get at least something when diffing different entity types, instead of a 
bogus error message (example: 
https://www.wikidata.org/w/index.php?oldid=199788084=206027763).
  
  Since MediaInfo does not introduce any new features (yet), this will work 
with MediaInfo.

  Indeed, per my edit on test.wikipedia.org never making it to the recent 
changes table many edits will not have made it to the rc table on wikidata.org
  And if this is how WDQS picks up edits WDQS will have missed them.

[Wikidata-bugs] [Maniphest] [Commented On] T133046: WDQS stopped updating during datacenter switch

2016-04-19 Thread Gehel
Gehel added a comment.


  Looking at the code, it seems that updates are fetched by using the MW API. 
Doing the call manually from wdqs1001 seems to return meaningful data:
  
curl -v -s 
https://www.wikidata.org/w/api.php?format=json\=query\=recentchanges\=newer\=title\|ids\|timestamp\=100
  
  It seems that the recent changes as exposed by api.php are populated by job 
queue. Those updates were lost for a moment during the switch. We have lost 
entries in recentchanges during the switch, which means that WDQS has not seen 
those updates either...

using indexes. So *all* labels would need to be checked against the regular
expression, which of course times out.

But there are other options. Perhaps
instead of FILTER regex(?label, "^apparel")
try FILTER (STRSTARTS(?label,"apparel"))

See 

Another option would be Blazegraph's full text index:

WHERE {
  ?label bds:search "apparel*" .
  
}

This woudl match any label that contains a word that starts with apparel.

See

[Wikidata-bugs] [Maniphest] [Created] T133042: Quantity datatype precision (tracking)

2016-04-19 Thread Tobi_WMDE_SW
Tobi_WMDE_SW created this task.
Herald added a subscriber: TerraCodes.

TASK DESCRIPTION
  We discussed about quantity precision today and here's a way forward:
  
  - DataValue needs to support undefined precision
  - Remove "guessing" of precision from parser
  - Change formatters to always show the precision when defined
- Note: this will cause that +-0 is shown where it is defined as precision
  - Guess the precision where needed (e.g. for unit conversion, indexing and 
RDF export)
- Change the guessing algorithm to guess precision of +-0.5
- Open question: how to handle numbers with no decimals? e.g. 2300 could 
have +-0.5 or +-50
  - Create bot that removes precision that matches the previous guessing 
algorithm
- Open question: should precision +-0 be removed from properties that 
represent counts? Or should properties for counts get an own datatype?
  
  Some of the above points do have existing tickets already. @Daniel 
@thiemowmde @janzerebecki can you double-check the list and link the tickets?

  Side note: nginx computes etags based on last modified date and file size. 
The last modified date might differ (not much, but enough) between our 2 
servers, which means that we might have inconsistent etags. We should probably 
disable them...

2016-04-19 Thread Gehel
Gehel added a comment.


  Strange ... Having a quick look at the HTTP responses and our nginx 
configuration, it seems that the only resource on which we set caching headers 
are the queries themselves (everything under `/bigdata/namespace/wdq/sparql`), 
and even then we send a max-age=60. We do send appropriate etags and last 
modified headers on static resources (CSS, JS, images, ...). Note that we 
should certainly have those static resources be content based addressed and 
have long lasting caching headers.
  
  @Jonas do you have an example of a resource which stays cached for longer 
than expected?

Re: [Wikidata] SPARQL service timeouts

2016-04-19 Thread Guillaume Lederrey
I'm late to the game, but a quick look into the nginx logs does not
show all that much. I see a few connection refused, but that should
translate in an HTTP 502 error, not in a partial answer.

I'm really not good at reading VCL, but it seems that we do have some
rules in our Varnish config to cache pages in error. This would make
sense as pages in error tend to be expensive, so we probably want to
ensure the same error is capped at a maximum rate.

I'll keep looking. But transient errors are hard...

  I'm missing a bit of context here. All the editing on Wikidata is done with 
javascript that talks with the api. Somewhere between me (the user clicking 
around) and the api assert should be set so if I get logged out for some 
reason, it doesn't edit, but return a warning. @Lydia_Pintscher can you put 
this in the right wikibase-* queue?

Re: [Wikidata] SPARQL service timeouts

2016-04-19 Thread Addshore
Yes the size reported there will be the compressed size, so actual bytes
over the port!

Looking at the patch further it looks like some nginx settings were changed
while caching was enabled that may also be worth looking at.

I expect this will include error results from timeouts so retrying a
request within the same 60 seconds as the first won't event reach the
WDQS servers now.


Maybe this could be the answer. Is it possible that the cache stores the 
truncated result but not the Java exception? Then the behaviour could be 
a timeout which just is not reported properly. Ideally, partial results 
should not be cached or the "timeout" should be cached so that a renewed 
request (in 60sec) returns an immediate timeout rather than a broken 
result set.


Cheers,

Thus you will only see a spike on the graph for the amount of data
actually sent from the server, not the size of the result blazegraph
was trying to send back.

I also ran into this with some simple queries that returned big sets
of data.
Although with my issue I did actually also see a Java exception
somewhere.

Ok, I found that this is not so easy to reproduce reliably. The
symptom I am seeing is a truncated JSON response, which just
stops in the middle of the data (at a random location, but
usually early on), and which is *not* followed by any error
message. The stream just ends.

So far, I could only get this in Java, not in Python, and it
does not always happen. If successful, the result is about 250M
in size. The following Python script can retrieve it:

import requests
SPARQL_SERVICE_URL = 'https://query.wikidata.org/sparql'
query = """SELECT ?subC ?supC WHERE { ?subC p:P279/ps:P279 ?supC
}"""
print requests.get(SPARQL_SERVICE_URL, params={'query': query,
'format': 'json'}).text

(output should be redirected to a file)

I will keep an eye on the issue, but I don't know how to debug
this any further now, since it started to work without me
changing any code.

I also wonder how to read the dashboard after all. In spite of
me repeating an experiment that creates a 250M result file for
five times in the past few minutes, the "Bytes out" figure
remains below a few MB for most of the time.

I successfully got five files of 250M JSON each, but even those 
successful queries did not show up in the stats. The five files had 
three different versions (slightly different sizes) so they did not all 
come from a common cache either. Maybe the size is counted in terms of 
compressed or otherwise "raw" results?




I also ran into this with some simple queries that returned big sets of
data.
Although with my issue I did actually also see a Java exception somewhere.


I know the case where large result sets end in a Java timeout exception. 
This occurs reproducibly when you retrieve all humans or something like 
that. However, in my case, the behaviour is not always reproducible and 
there is no Java exception at the end of the output; it just stops in 
the middle of the file.

are now cached for 60 seconds.
I expect this will include error results from timeouts so retrying a
