XMPP Summit - 2013-07-29

yusuke: about your dependency graph, do you have the actual data and not just the graph?

yusuke: or maybe the script? because I also want to do some statistics, before we make the tagging, versioning etc.

Steffen Larsen, there are ready to use python libs for that: https://gitorious.org/xmpp/xmpp/blobs/master/extensions/xepinfo.py

so you basically give it a path to a mercurial info and the lib will automatically fetch versions and stuff...at least that was the plan

hello

Tobias: super! I did not know that

Steffen Larsen, do you know where to get some nice not too expensive here?

strohl: where and what?

interconti(berlin) not poisened stuff ;) something lunchlike

ha ha

Just got back in copenhagen yesterday.. but there is a lot of beer gardens around tiergarten

haven't eaten at the intercontinental hotel

ah ok

maybe i simply try to find a subway, near trainstation zoo should be one

yes but also in the tiergarten are like 2-3

next to the tiergarten trainstation is also a good one..

but thats about 1km away, too, hmm

heh .. otherwise in the tiergarten next to the soo is a big one..

this one: http://www.cafe-am-neuen-see.de

there we was yesterday evenign ^^

yes!

the food is ok.. but a bit fried

:-)

hehe

well speaking of food.. I'm off to lunch

k thx

hehe

its raining :|

Tobias: Just a stupid quesiton.. are we not having the latest XEPs and docs in git (gittorious) and not in mercurial?

Tobias: havent touched the xmpp.org code/doc since 2009 in svn.. so please forgive me and my stupid question. :-)

Steffen Larsen, we use git as source control...however mercurial has a nicer python API, so the tools are written in python :)

and hg has quite good git support via hggit

Tobias: ahhh ok.

Tobias: no prob. I know both hg (mercurial) and git

Tobias: just wanted to look into tagging ,referencing and versioning in the XEPs

Steffen Larsen, right..we could auto generate small dependency graphs per XEP and show them at the end of the XEP

yes

Just looking at it now.. many have <dependencies> tag.. but not all are maintained I think

they could be manually verified if a XEPs status moves up...i.e. experimental -> draft, draft -> final, ...

Tobias: versioning of XEP and xsd is not that easy.. the XEP contains <revision> and <version> but is it deterministic to see which one is the latest? of course for most of the time it is the first, but still..

Tobias: yes

XEP's have revision? you mean svn/hg/git revision?

there is revision tag in the XEP it self

or is it based on SCM/git

?

ahh..i see what you mean

:-)

i'd say version is just the textual representation of a revision

yes. changing a comma might not change the flow or the XSD..

looking at https://gitorious.org/xmpp/xmpp/blobs/master/extensions/xep-0045.xml

ok.

you mean version tag and revision tag, right?

ye

yes

heh MUC.. not the lightest XEP ;-)

right...but i thought it's old enough to cover all features

Tobias: right

so for getting the actual latest version of a particular revision: https://gitorious.org/xmpp/xmpp/blobs/master/extensions/xeputil.py

I just wanted the version of a XEP.. because many XMPP servers say that they e.g. implement MUC, but in what version?.. if they implemented it way back it might not be compatible with our new version

def contentOfRevision(self, revision) <-- will give you the latest XML that got tagged with exactly that revision

ok

maybe a service disc. could deliver the version as well besides namespace?.. just to be more trustworthy

ohh that might already be included.. hmm

reading up on http://xmpp.org/extensions/xep-0053.html .. does it means that the authors SHOULD update the namespace with a version, if flow or protocol changes?.. and is it done in real life?

Tobias: e.g. MUC ns: http://jabber.org/protocol/muc .. should that have been versioned? like http://jabber.org/protocol/muc:1 etc..

Sorry for spamming the summit MUC.. i'll PM tobi. :-)

Steffen Larsen, good question...i'm not that up to date with the current namespacing approach...but yeah...usually we now do foo-bla:#version

exactly.. buy they need to be updated not only when chageing status but also during draft etc.

Tobias: I've added you to my Roster for further discussion. ;)

Steffen Larsen, yeah..took some time to find it in my UI :P

:-)
