[Twisted-Python] Contributing to Twisted
by Michal Pasternak Nov. 24, 2003

Nov. 24, 2003

Hi, I'd like to setup buildbot on my machine and help Twisted building and testing packages - as my contribution to Twisted project. I can install it on a 700 MHz / 256 RAM / NetBSD-stable machine. Do you accept such submissions? Who should I contact about it? Take care, -- Michal Pasternak :: http://pasternak.w.lub.pl

[Twisted-Python] Woven problems after upgrading to 1.1.1rc1
by Justin Johnson Nov. 24, 2003

Nov. 24, 2003

After upgrading to 1.1.1rc1, when I startup my tap which starts up a web server and a flash conduit server for LivePage, as soon as I try to access the page with my browser, I get a never ending stream of log entries as seen below. I've attached 2 files, tap.py and pages.py, which contain most of the code involved. Let me know if anything else is needed. 2003/11/24 09:18 CST [-] Log opened. 2003/11/24 09:18 CST [-] twistd 1.1.1rc1 (/usr/local/bin/python 2.3.0) starting up 2003/11/24 09:18 … [View More]

[Twisted-Python] Unit test
by RITA Y/O RODRIGO DIAZ Y/O BENENSON Nov. 24, 2003

Nov. 24, 2003

Short question, which is the adecuate way of doing unit test of a sequence of defered events ? one chained to the other. If each deferred need a callback method, I have already more that thirty functiones defined, and each time I need more. How to do it ? defered = something <the magic> defered = the_next_thing # that need the previous defered to have been acomplished etc... I can imagine various tricks, but I supose there is a standart way. Thanks. RodrigoB.

[Twisted-Python] web/client.py add parameter to get raw redirects
by Clark C. Evans Nov. 24, 2003

Nov. 24, 2003

Hello. I'm working on some testing harness for my application (in twisted, of course) and I found I needed to record when the app is expected to send back a redirect. So, this needed a few changes in client.py ; if this seems resonable, I can commit it. - Clark ... --- client.py.bc Sun Nov 23 23:45:10 2003 +++ client.py Mon Nov 24 03:46:55 2003 @@ -28,10 +28,19 @@ from twisted.web import error import urlparse, os, types +from twisted.internet.error import ConnectionDone +class … [View More]

[Twisted-Python] GUI Integration
by Thorsten Henninger Nov. 23, 2003

Nov. 23, 2003

Hi all, I would like to integrate the PerspectiveBorker into a platform-independant GUI. If I use Delphi for example, I include the twisted-reactor via the Python Deplhi Interface. But then if I call "reactor.run()" this blocks the Delphi Application! Since wxPython for is not supported for Windows yet, and I do not want to use GTK or PyGui, my question is: How can I integrate the twisted framework into a GUI environment such as Delphi? Or do I have to use Java? Can I run the reactor in … [View More]

[Twisted-Python] tap2ntsvc future
by Cory Dodt Nov. 22, 2003

Nov. 22, 2003

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've finished the initial work on tap2ntsvc. This script does the tedious work of creating an installer around your Twisted service. A quick howto: 1. Create a tap or tac file for your application, using the method you normally use. **Test with twistd to make sure that you can start the app from the command line, _before_ you wrap a service around it.** 2. Acquire and install the prerequisites of tap2ntsvc. It depends on software outside of … [View More]Twisted, specifically: win32all @ http://starship.python.net/crew/mhammond/win32/Downloads.html Innoconda @ http://twistedmatrix.com/~moonfallen/innoconda.html 3. Run tap2ntsvc from the command line. (*This is not yet integrated with the "Twisted Command Prompt" available on MSWindows with the official Twisted installer, but it will be when the script becomes an official part of Twisted.) Use --help to get the command line options. To start with, all you need to provide is the name of your tap or tac file. | python .../Twisted/sandbox/moonfallen/tap2ntsvc myapp.tac This will build an installable package using Innoconda. 4. Install the package. It will be in myappsvc/myapp-...-setup.exe. 5. Start the service; it will fail, but you'll find out what modules you need to add. | net start myapp **It's ok if this doesn't work.** 6. Check the Application event log to find out what modules failed to import; you will be re-running py2exe after you add the missing modules. 7. Either: (a) re-run tap2ntsvc with the -i option or (b) add your modules to myappsvc/setup.cfg on the "includes=" line. If you choose to do the latter, read myappsvc/README.txt to find out how to recompile just the parts you need. 8. Redo steps 3 through 7 until you no longer get ImportErrors in the Application log. 9. Some applications need data files. If you need data files in your application, consult myappsvc/README.txt and edit myappsvc/myapp.fms. myapp.fms uses a special command language to make adding data files as intuitive as possible. You can put files in c:\Program Files\myapp or any subdirectory thereof, so make sure your application code can find data files there. When you're done, you should be able to 'net start myapp' successfully. ~ When you want to rebuild it in the future, just keep these files in your version control: ~ myappsvc/do_inno_script.py ~ do_inno.py ~ setup.cfg ~ setup.py ~ myapp.fms Caveats, bugs, TODO: - - you must be able to start your application in py2exe. Things most likely to not work are finding important data files based on the value of __file__ in some module. - - if you install the same service multiple times without uninstalling it in between installs, then start it, then uninstall it, it will crash on uninstall. Just be sure to uninstall it in between installs while you're experimenting. - - I want to make the module finder more foolproof, saving several of the steps above. This is a non-trivial problem, however. - - Really, it needs a frontend. And I hate Tk. Can I put a Gtk app into ~ Twisted proper? :-) The future: I want to move tap2ntsvc out of sandbox and into main Twisted. I want people to read this email over and try it before I do so, in case there are important concerns I need to address. We need to give some thought to what to do about the 2 significant dependencies. Should this block tap2ntsvc from being in Twisted proper? Is there a policy for this sort of thing?

[Twisted-Python] reactor/transport/protocol relationship?
by John Benson Nov. 20, 2003

Nov. 20, 2003

>From the http://www.itamarst.org/writings/OSCON03/twisted_internet-18.html slide, I gather that objects in twisted connect as follows: (internet cloud) <---> transport <---> reactor <---> protocol In the http://www.itamarst.org/writings/OSCON03/twisted_internet-19.html diagram however, there is a different connectivity. What am I missing here?

[Twisted-Python] wvfactory
by vicky lupien Nov. 20, 2003

Nov. 20, 2003

I have a form in a web page and I need to fill it with many sql queries but only the first time the page is rendered. The other times, I want to fill it with the data from request.args. I decided to build a dictionnary that looks like the dictionnary of request.args to be able to use only one function to validate and fill my form. My function that fill my forms need to receive the dictionnary, the document(node that I need to change) and a signature (signature is a list of the name and the … [View More]type of each elements from the form that need to be fill). In my template, I defined a wmfactory in the tag <form> that return my dictionnary. Ive also define a wvfactory that call my function to fill the form. The problems is that wmfactory return a deferred so in wvfactory I have to call my function to fill like this: return model.getData(request).addCallback(my function). But I think that return doesnt wait that the addCallback is done. Is there something I can do to make my returns wait for the addCallback to return the new node filled with the dictionnary of data. Heres a part of my code: #verify is the function that fill and verify my form class handle: def __init__(self): pass def verify(self, dict, doc, signature): # dict is the dictionnary from the sql queries of the request.args # doc is the node <form> and its child error = 0 for item in signature: nodeList = domhelpers.locateNodes(doc, 'name', item[0]) #INTEGER, FLOAT and STRING if item[1] == 'integer' or item[1] == 'float' or item[1] == 'string': pass #CHECKBOX elif item[1] == 'checkbox': for node in nodeList: # dict est None s'il n'est pas cochee if dict.get(item[0]) != None and str(node.getAttribute('value')) in dict.get(item[0]): print 'checked' node.setAttribute('checked', 'checked') print node else: if item[2] == 'true': error = 1 l = microdom.lmx(node) l.span(style='color: red').text('donnees obligatoires') return doc # class that execute the queries needed class SummaryEditDB: def __init__(self, dbpool): self.dbpool = dbpool def getSummary(self, plan_id): sql = "select * from plan where plan_id = '%s'" %plan_id return self.dbpool.runQueryDict(sql) def getCategoriesIdByPlanId(self, plan_id): sql = """select to_plan_category_id from plan_categories where to_plan_id='%s' order by to_plan_category_id""" % plan_id return self.dbpool.runQueryDict(sql) class SummaryEditPage(pages.BasePage): templateFile = "summary_edit.html" def initialize(self, dbpool, *args): self.dbpool = dbpool self.db = SummaryEditDB(self.dbpool) self.signature = (('categories', 'checkbox', 'false', 'valeurs non correctes')) def executeSQL(self, plan_id): def createSummaryDict(results, newDict): for item in results[0]: for elem in self.signature: if item == elem[0]: newDict[item] = results[0][item] return self.db.getCategoriesIdByPlanId(plan_id).addCallback(createCategoriesDic t, newDict) def createCategoriesDict(results, newDict): newDict['categories'] = [] for item in results: newDict['categories'].append(str(item.get('to_plan_category_id'))) return newDict newDict = {} return self.db.getSummary(plan_id).addCallback(createSummaryDict, newDict) # first addCallback to fill the dictionnary def setUp(self, request, *args): self.planData = self.executeSQL(plan_id) #this call the function that return the dictionnary with the data (deferred) def wmfactory_planData(self, request): return self.planData # Usually, when I return an SQL queries, the model is not deferred but in this case, it is def wvfactory_fillFromSQL(self, request, node, model): def format(results): print results return handle().verify(results, node, self.signature) # the function that fill the form (replace attributes in the node) return self.planData.addCallback(format) # to be able to see the results of self.planData, I need to use a addCallback to be able to see the results and to call the form filler.
