[Twisted-Python] Perspective Broker for Java works!
by Itamar Shtull-Trauring Nov. 7, 2001

Nov. 7, 2001

Hi everyone, Just a status report - PB for Java is up to the point where it can connect to the simple example service in doc/examples/pbsimple.py and get the response. Which means that implementing a (very) basic implementation with equivalent functionality to XML-RPC takes about 3 days. As always, I'd appreciate any help in making this a complete implementation.

Um, okay. But why? Your commit just added an extra line to every place in the codebase which created a Perspective, without making that code any more expressive. If Perspectives in fact only exist to provide a perspective to a specific service, in what situation would you create Perspectives without having a Service to pass to the constructor? Even given the existance of such situations, Service.createPerspective is decidedly *not* one of them. Why does a Perspective returned from a Service method -- which has been added to the Service's list of perspectives -- not have its service attribute set? -- The moon is waning gibbous, 80.7% illuminated, 19.0 days old.

[Twisted-Python] Twisted 0.12.0

I'm not one for PR writing, so this is short. ;) There's a new Twisted release at http://twistedmatrix.com. It's a major feature enhancement and bug-fix release, and it went rather smoothly -- if you'll notice, everyone's personal webservers on zaibach are still running, even without needing a restart :-) -- Chris Armstrong | carmstro(a)twistedmatrix.com | cjast3(a)robert-morris.edu Web Page: http://purl.org/net/ChrisArmstrong

Hi everyone, I've started working on a PB implementation for Java. Banana support is finished, next up is jelly support, and then finally pb support. If anyone is interested in helping please contact me, on #python or by email. Cheers!

[Twisted-Python] ingtkernet._conditions

In Twisted/twisted/internet/ingtkernet.py revision 1.3: > _conditions = { > gtk.GDK.INPUT_READ: 'Read', > gtk.GDK.INPUT_WRITE: 'Write', > > # This is here because SOMETIMES, GTK tells us about this > # condition (wtf is 3!?! GDK.INPUT_EXCEPTION is 4!) even though we These are *bit flags*, so 3 is INPUT_READ & INPUT_WRITE. I'm not sure what the correct course of action is to take here; I tried calling both doRead and doWrite, but that only resulted in brokenness. > # don't ask. I believe this is almost always indicative of a > # closed connection. > 3: 'Read' > } Also relevant in the description of the GDK.INPUT_READ flag: ] the file descriptor has become available for reading.

[Twisted-Python] The never-ending quest for 1.0
by Chris Armstrong Nov. 1, 2001

Nov. 1, 2001

Well, glyph has guilted me into trying out this "release manager" thing tonight, since I, like, don't actually code anything. I'm gonna _try_ to get 0.12.0 out tomorrow (well, later today), but my girlfriend might rip me away from my computer (friday night, and all). If I don't have it released by the weekend, (and it's not because of a bunch of bugs), then I give you permission to hunt me down and lynch me for my lack of responsibility. Speaking of responsibility, I think release manager might actually fit me somewhat, since it's not such a consistent thing, and doesn't directly involve much coding (i get to yell at whoever made a bug, unless they're not around, in which case I would try to find another idle twisted.minion to persuade to fix the bug, and if none of those around, only THEN will I attempt to fix a bug myself ;) ;)) My humour would probably be more on the ball, but I'm not in top shape today (yeah yeah, I know you're thinking "what humour?"). sorry. -- Chris Armstrong <carmstro(a)twistedmatrix.com> http://twistedmatrix.com/users/carmstro.twistd/

[Twisted-Python] Enterprise, do you copy?
by Kevin Turner Nov. 1, 2001

Nov. 1, 2001

...hello? Hello? Is anyone receiving this transmission? I heard from Dad again today, and he was grumbling about developing in this Oracle JDeveloper environment... Five different languages to develop "java server[servlet?] pages", he says. Java, because that's where Oracle seems to be building its tools these days; then there's Oracle's query language; then HTML for the web interfaces; and JavaScript, because there's something that needs to be done client-side, and, uh, what was the fifth one again? Then there's the hundreds of functions the wizards create for simple tasks, spread across untold numbers of files... Ye gods, man. Can anyone save this tragedy? I can't give you a complete list of requirements, but the general gist is this: The laboratory has researchers and machines, the researchers do experiments and the machines spit out data. Quite a bit of data. This data comes out in raw form, needs to be stored, processed, the results stored. It'd be nice to keep track of which data actually belongs to what run of whose experiment -- it seems like they lose track of that every now and then. Anyway, data (lots, but still in the fractional-terabyte range) stored in Oracle, and, naturally, cross-referenced with other data, and, well, there's a lot of that going around. The researchers, who spend most of their time knocking the brains out of mice instead of clicking on them, need relatively friendly interfaces to the data from their experiments, and for shoveling it around between these various phases of analysis. They hope to add some internet soon, so they can pool data from their distributed colleagues. So, I gotta ask. What's the status of twisted.enterprise these days? With Oracle? Webwidgets would help with the web bit, but they'd still need to write javascript to keep the forms from being completely dumb? Or can you convince them that there's another interface that's portable and *drop-dead-easy* to maintain on the client machines, which he can use as an alternative to web? Is there an IDE which can make up for all the shiny things which the Oracle tools have? If I didn't make the situation sound scary enough before, here's the truly horrifying detail: there's another faction among the computer-guys in the lab which wants to use _exclusively_ Perl. I don't think it's too late. They're still making up their minds. But if there's another option, they've got to know soon, before they're wholly consumed by the dark side. And whatever it is, it's got to do a damn _impressive_ job of selling itself, to overcome both that warm fuzzy feeling imparted by the "Larry Ellison" brand, and the deap zealotry of the Perl encampment. May peace be with you, - Kevin -- The moon is waxing gibbous, 99.9% illuminated, 14.5 days old.
