adhawkins-away: sounds like you're making progress!

cool, got ingestr running

I mean, it doesn't actually *do* anything since I have no data, but :P

get some data then!

You have the IA data!

Use it :p

at present it really only supports some datasets I don't have :P but yes, that'll be my next step

ianmcorvidae: while you're at it, it could probably use some option to add releases in low quality by default :p

initially, it won't support adding releases at all :P it needs to get data into its own DB before it can worry about getting it into MB's

Ooh

cool

Import the Naxos Music Library :p

Or the BIS site, or Chandos or Hyperion or or or

So many things I'd love to see ingested...

I think I'll start with the IA data :P

Sure, sure

Ingest it all!

does it have any options to find dupes?

(from multiple datasets)

I guess it doesn't need them yet, but it will at some point

that'll be your job :P

the point here is to ingest things and then have it be a data source for editors

with the ultimate goal being finding mappings so we can create importers

(but also getting some mappings between datasets (including to/from our data) in the process)

ianmcorvidae: sure, but if we import, say, the IA data and data from one label, it would be great if it could tell "heeey, these look the same"!

*!"

that might happen eventually, yeah

ultimately the hope would be that we'd have mappings for both datasets and we'd be able to be like "hm so these look the same in this normalized form"

warp: http://tickets.musicbrainz.org/browse/MBS-5540 could you look into this when you have the time?

It's... fairly annoying

ocharles: Ping

Another DB issue: https://gist.github.com/3990519

I didn't download the edit file (just editors). Could it be that? I've never bothered with that one previously.

yeah, there's a bug for that, there's some stuff in the CAA foreign keys file that makes the CAA dump potentially depend on the edit dump

workaround is to comment out the relevant foreign key in the file, or to get the edit dump (I'd recommend the former, personally)

Which file do I edit/

?

admin/sql/caa/CreateFKConstraints.sql lines 12-15

Just comment them out?

yeah

Ok, while you're here, you're responsible for the code that generates the dumps aren't you?

reminding since I don't remember how often you use SQL that '--' is comment in SQL, not #

'Never', so thanks for the reminder :)

inasmuch as I'm in some sense responsible for all the code, at least :)

well, there's a comment up at the top of the file which might have also reminded you, but :)

I'm considering knocking up a script that will download the latest dump (optionally including the edits file).

It'd be a bit easier if instead of a 'latest is xxx' file, there was a file called 'latest', whose contents contained the path.

Then you just wget 'latest', look in the file and wget the rest.

Or can wget do 'ftp://blah/latest-*'?

yeah; I'm not sure why we do that the way we do

wget should be able to do wildcards with ftp urls, yes

of course at present the latest-is file really doesn't do anything except provide a filename you can parse, so :P

Yeah, but I can do that at the shell if necessary.

I'll have a play.

perhaps make a ticket for the changing-the-format thing; I'd like to ask ruaok about it at least, but otherwise I don't see reason not to do that

You could always have both so it's easier for users looking for the latest *and* scripts.

yeah, we'd keep the current latest-is files for compatibility

Yep

Ok, re-running the import. Shame it gets almost to the end before failing :)

What category should that dump ticket be in?

uh

unsure

I'll put it in server for now, someone can move it if necessary.

oh, you mean which project? yeah, MBS

Sorry :)

Misc Features?

nah, my fault, should go to bed soon

Scripts?

eh, don't bother with a component for now, none of them look particularly correct

MBS-5541

great, thanks

ocharles: Ok, data imported, but nothing listening in the VM on port 5000. How do I start up the server?

Will start again (again!) :)

woah. I'm late.

adhawkins, ianmcorvidae: djce might know, since I'm pretty sure he's the one who created it originally

nikki: This is ocharles new fab and groovy auto-creating VM based on Vagrant and Chef...

adhawkins: I mean the "latest" file

Ah I see :)

Crossed conversations. Anyway, there's a ticket in place for discussion now.

I do remember that it's not a symlink, in case the symlink changes halfway through someone downloading

but I don't remember why it's latest-$timestamp and not latest containing the timestamp...

probably just that it was done the former way before anyone realised it wasn't the most optimal way

it is the optimal way in the sense that you don't need to perform an extra request

oh?

(ok, if you hit latest instead of the index it would be the same amount of requests :)

hm, it looks like my code for getting the timestamp of the latest dump is 8 lines of code when I could do it in 1 if the latest file contained the timestamp (well, 9 and 2 respectively if you include including the relevant modules)

wget -x -m -np `lynx -dump 'http://ftp.musicbrainz.org/pub/musicbrainz/data/fullexport/' | grep 'http://' | awk '{ print $2 }' | grep 'latest-is' | sed 's/latest-is-//'`

that works, though is ugly.

we should just build downloading a full-export into our database provisioning tools :)

that doesn't help if that's not what you're trying to do

e.g. the code I just looked at does not come from a script for downloading a full dump

adhawkins: heh, http://tickets.musicbrainz.org/browse/OTHER-17

Great minds eh? :)

well, I just copied it from trac :P

but I do agree

./admin/InitDb.pl --createdb --import

Whoops

morning

Morning (just!)

ya, just...

Oh god, my import is failing again...

Any ideas?

it looks like there's something wrong with the settings for the postgres user

but I've not seen that before, so I'm not entirely sure

Grr...it's been working before.

One thing after another! :)

that's odd then :/

Story of my life :)

Ok, blow the whole thing away and start again (again!)

ocharles: When you've got a mo, I'd like to talk to you about a few ideas I've got for the VM, and discuss workflow.

sure thing

lets talk :)

adhawkins: you don't need to start again I wouldn't have thought

really 'vagrant provision' should get you to the same place

it seems that you just need to restart postgresql because something in provision isn't quite doing that correctly

I think if it's already git cloned, it seems to throw an error.

Ah, restarting postgres, I'll remember that next time :)

What you want to cover first, workflow? Or ideas?

whichever is easiest for you

Workflow then.

I've cloned your top level repo, and your cookbooks one.
