XSF Discussion - 2013-01-25

switching to using some form of UUID would eliminate having to deal with converting relative/full paths though

well, it is certaintly more simple

i like it

honestly, I would probably even go one further and move the <file /> element into the fis namespace

but, using the existing one does make sense, since you'll want to do file transfer. so idk

yea, it is better to reuse what we have already

and we don't really need to add or remove anything from the metadata defined in jingle

right. so that works great as is

are you going to Fosdem?

yeah. the summit and saturday at fosdem

that's awesome

I also have: https://gist.github.com/4630085

to play with doing things with disco

hey lance

are you a PSF member?

I dont think so

would you like to be?

sure

perk: special members luncheon at PyCon

all current and prospective members can attend

sounds like the XSF perks

pretty much lol except we dont do voting every quarter

application process?

via nomination, and then you're voted in person at the luncheon

ah, ok

do you maintain any python packages beyond Sleek?

Not anymore. There were a few personal ones a while back that have been obsoleted and removed

ok

I may end up with a whole collection of them if I go with making each sleek plugin a separate package

heh

the independent versioning that way is very tempting

well i need to writeup a nomination about things you do in the python community. anything else i can add, like speaking at groups, sprints, etc?

unfortunately, sleek has been my only involvement in the greater python community so far

all of the groups and hackathons i've done have been at xsf functions

oh will you be staying for the sprints at pycon?

(thats when the real fun at pycon begins, btw)

maybe. i still have to review the schedules and what my work schedule allows

the weekend is for the suits. they go to these massive talks and rub shoulders with us. then the conference suddenly drops to just developers and the booze and shenanegans start up

Jef: I sent a link with some disco pondering, in case you missed it in the chat history

so much work gets done during the sprints too

sounds good, I'll try to be there then

when fosdem is over we should start hammering out the poster. 4' x 4' infographic.

hey lance, quick "which is more pythonic" opinion

right now the class decorator for xslt extensions is nodetree.Stylesheet.extension, eg: @nodetree.Stylesheet.extension('http://example.com/namespace') class MyExtension:

the reason thats a decorator and not a superclass is the decorator registers the class to the namespace url, which a superclass couldn't do in response to defining the class

writing a set of method decorators which "register" methods within it as either function or element extensions, which looks more pythonic:

@nodetree.Stylesheet.ext_function('hello') def hello(self, args) : return 'hello, world!'

or @nodetree.Stylesheet.Extension.function('hello') def hello(self, args) :

arcriley: one sec, reading

the latter is more verbose and an extra level of namespace, but i think it looks cleaner and i like that the association between class and method decorators is clear

tho four levels of namespace starts to feel like java

what are you extending? ie, what is 'hello'?

XSLT. so, eg, "<exam:hello/>" in the XSLT would be replaced with an xml text node "hello, world!"

ok, so that's the xpath for the template

actually sorry i confused it, function would be xpath yes, where element would be my example

the class decorator Element registers the defined class with libxslt and stores it in Stylesheet.__extensions for later access.

what else falls in Extension?

that's about it. as a type it needs to hold the uri you're defining long enough to wrap, and then its cleaned up. its just a decorator

i'd just go with @nodetree.Stylesheet.extension

and just do the appropriate thing if given a function or a class

eh?

the question is how to name the method decorators

oh, i think i'm confused from too many converstations

without them, there's no way to know whether a method is for a function or element, or potentially other extension point

do you have an example of a class with these in use?

no because im writing the code right now :-)

brand new API.

I'd either go with the ext_* version

or make the extension type a parameter

@nodetree.Stylesheet.extend('function', ....)

sorry, have to go to an appointmen

no prob im talking to a few people about this

sigh, why do most clients display adhoc command forms in the ugliest ways?

Lance: good question

Lance: clearly someone needs to develop a sleek new client on top of SleekXMPP ;-)

there's poezio, but its console only

the other thing we could do is complete the voting on a website and use the JIDs for XEP-0070 authorization

do any clients support that?

I have not tested it in a long time

or rather, do browsers support it

clients only have to display a link

ok, looks like just digest-md5, so they should

yeah, ultra-secure digest-md5!

what I really want in a client is one that displays message forms inline with chats

is that actually used by anyone?

they would if they showed up inline

it would just make interacting with bots so much nicer. an actual form instead of pseudo-form text commands

WWW-Authenticate: Basic realm="xmpp" Do any browsers actually use that? ^^

ooh

client aside thats the big issue I see

we'd have to test, but I think they would

that'd have to use some javascript hook im not aware of

oh, basic

i was thinking of the digest one

either

the realm option is pretty standard though, its just not a domain in this case

oh, but it would also try asking for a password

IIRC when you get a authorization request a dialog opens requesting your username/password.

and you would then have to script to return your JID, etc etc

username would be your jid, and empty password

er, no. the password is the transaction id

how would the user have a transaction ID?

it gets sent to your JID via your xmpp client

copy/paste

is there a javascript hook for that?

it is certainly not the most user friendly workflow

not that i'm aware of. it would certainly make it a smoother process

but it can still be done manually

this really is a case where cridland's 'browsers need to run xmpp natively' idea shines

i agree with that.

its a chicken and egg problem tho.

chrome already does it for syncing apparently; it would be nice if it was just more exposed and configurable

the big problem that needs to be worked out is the javascript security model for it. how to keep malicious websites from sending xmpp spam on your behalf, stealing your contact data, etc while also providing enough functionality to be genuinely useful

right

couldn't the transationid/password dealio be handled like oauth tokens

that way the owner of the jid could revoke an apps use of their xmpp stream

and have it tied directly to a resource part of the jid

hell, make it bear@jid.com/transactionid
