this is what I tried:

is decoded_data an array reference? then you need to do $decoded_data->[0]

oh that might be the case

$log_stat->data(Dumper($decoded_data->[0])); this produces this hash on the output:
2012-07-21 20355, 2012
7:58 AM
plaintext
{ 'count' => '9', 'percent' => '0.900000', '_tc' => '1000', 'mbid' => '60f7d020-9580-47c5-8839-a4f25659687d' }
2012-07-21 20327, 2012
7:59 AM
plaintext
but this: $log_stat->data(Dumper(keys %{ $decoded_data->[0] } )); produces the single string 'count' for some reason
2012-07-21 20351, 2012
7:59 AM
plaintext
however when I try $decoded_data->[0]{'percent'} it works without a problem
2012-07-21 20359, 2012
7:59 AM
plaintext
why cant the keys function return all the keys in a list?
2012-07-21 20356, 2012

keys returns an array, not an array ref. is Dumper expecting an array ref perhaps?
2012-07-21 20324, 2012
8:02 AM
plaintext
I thought dumper would just output any variable
2012-07-21 20319, 2012
8:03 AM
bitmap
it does expect a reference iirc
2012-07-21 20344, 2012
8:03 AM
warp
oh, probably Dumper generates an array if given an array, and $log_stat->data() only uses the first argument.
2012-07-21 20302, 2012
8:04 AM
plaintext
That may be so
2012-07-21 20356, 2012
8:04 AM
plaintext
That's right, thanks warp
2012-07-21 20321, 2012
8:05 AM
plaintext
I was expecting Dumper to output the whole array like when it dumped $decoded_data
2012-07-21 20326, 2012
8:05 AM
plaintext
which is an array of hashes
2012-07-21 20312, 2012
8:06 AM
warp
plaintext: well, it does. it's just that $log_stat->data() isn't expecting that.
2012-07-21 20305, 2012

oh I get it

2012-07-21 20312, 2012

@navap : Thanks for your reply .. I am using my school network to install it on one of the servers. I read the documentation for setting up the musicbrainz server . Is there any way I can use the existing apache server to host this
2012-07-21 20313, 2012
19:11 PM
navap
There probably is, but I've only used the built in catalyst server so I won't be much help in setting up something else
2012-07-21 20323, 2012
19:15 PM
ianmcorvidae
you'll need to set up apache as a reverse proxy to running the server with FCGI -- apache will be an extra layer "around" the main server
2012-07-21 20353, 2012
19:15 PM
ianmcorvidae
you can't run it with e.g. mod_perl or such, as far as I know, but it's run using Catalyst/PSGI/Plack, so if you want to look at those docs they might inform you

2012-07-21 20326, 2012

that's a separate component entirely
2012-07-21 20304, 2012
19:18 PM
ianmcorvidae
that's used only for search -- the perl server talks to that one (usually just via
search.musicbrainz.org , even for external deployments) as a backend for the search functionality
2012-07-21 20317, 2012
19:18 PM
ianmcorvidae
if you want the API, you'll need the perl server setup
2012-07-21 20338, 2012
19:23 PM
vinay_
Basically I want to use the APIs to extract information , but the APIs need a webservice .
2012-07-21 20310, 2012
19:24 PM
vinay_
Ok I will try the perl server setup
2012-07-21 20323, 2012
19:24 PM
vinay_
Thank You
2012-07-21 20326, 2012
19:24 PM

you could also just set up the database, if you just want any old access to the data
2012-07-21 20357, 2012
19:24 PM
ianmcorvidae
but yeah, look into the perl server setup :)
2012-07-21 20338, 2012
19:25 PM
vinay_
And when I use the APIs musicbrains blocks us after some requests
2012-07-21 20309, 2012
19:26 PM
ianmcorvidae
there's a rate-limit, yes, one per second

I wrote programs to extarct data from the database but wanted to see if by using the APIs will it be any faster
2012-07-21 20337, 2012
19:47 PM
kepstin
the apis will be slower than directly accessing the data from the database, of course. All they do is add an extra layer between you in the database.
2012-07-21 20337, 2012
19:48 PM
ianmcorvidae
kepstin: probably -- the only exceptions might be if he's getting heavy usage of the cache or of the search indexes
2012-07-21 20335, 2012
19:49 PM
kepstin
the current etags implementation on the api doesn't actually stop it from doing the db request on 'cached' requests...
2012-07-21 20301, 2012
19:50 PM
kepstin
unless there's some other caching in the server itself?
2012-07-21 20325, 2012
19:50 PM
ianmcorvidae
yeah, I don't mean etags, I mean object caching
2012-07-21 20330, 2012
19:50 PM
kepstin
I didn't think there was on the webservice, since invalidating such a cache on db updates is a problem.
2012-07-21 20307, 2012
19:51 PM
ianmcorvidae
I don't know exactly how it plays out or how well it works, but I know that there is some sort of cache
2012-07-21 20318, 2012
19:51 PM
ianmcorvidae
it's most effective for things like the list of languages though
2012-07-21 20323, 2012
19:51 PM
kepstin
I'm not familiar with that, though - and presumbly an application accessing the db directly could cache relevant stuff internally
2012-07-21 20333, 2012
19:51 PM
ianmcorvidae
yeah, it could
2012-07-21 20303, 2012
19:53 PM
ianmcorvidae
2012-07-21 20333, 2012
19:53 PM
ianmcorvidae
kepstin: it just does _delete_from_cache after any update, delete, or merge (from perl)
2012-07-21 20301, 2012
19:55 PM
ianmcorvidae
but yeah, in general the database should be faster :)
2012-07-21 20341, 2012
19:55 PM

I was just trying to see the performance but now I dont think its worth it :)
2012-07-21 20354, 2012
