• What git branching models actually work - the final question

  - by UncleCJ

  In our company we have successfully deployed git and we are currently using a simple trunk/release/hotfixes branching model. However, this has it's problems, I have some key issues of confusion in the community which would be awesome to have answered here. Maybe my hopes for an Alexander stroke are too great, quite possibly I'll decompose this question into more manageable issues, but here's my first shot. Workflows / branching models - below are the three main descriptions of this I have seen, but they are partially contradicting each other or don't go far enough to sort out the subsequent issues we've run into (as described below). Thus our team so far defaults to not so great solutions. Are you doing something better? gitworkflows(7) Manual Page (nvie) A successful Git branching model (reinh) A Git Workflow for Agile Teams Merging vs rebasing (tangled vs sequential history) - the bids on this are as confusing as it gets. Should one pull --rebase or wait with merging back to the mainline until your task is finished? Personally I lean towards merging since this preserves a visual illustration of on which base a task was started and finished, and I even prefer merge --no-ff for this purpose. It has other drawbacks however. Also many haven't realized the useful property of merging - that it isn't commutative (merging a topic branch into master does not mean merging master into the topic branch). I am looking for a natural workflow - sometimes mistakes happen because our procedures don't capture a specific situation with simple rules. For example a fix needed for earlier releases should of course be based sufficiently downstream to be possible to merge upstream into all branches necessary (is the usage of these terms clear enough?). However it happens that a fix makes it into the master before the developer realizes it should have been placed further downstream, and if that is already pushed (even worse, merged or something based on it) then the option remaining is cherry-picking, with it's associated perils... What simple rules like such do you use? Also in this is included the awkwardness of one topic branch necessarily excluding other topic branches (assuming they are branched from a common baseline). Developers don't want to finish a feature to start another one feeling like the code they just wrote is not there anymore How to avoid creating merge conflicts (due to cherry-pick)? What seems like a sure way to create a merge conflict is to cherry-pick between branches, they can never be merged again? Would applying the same commit in revert (how to do this?) in either branch possibly solve this situation? This is one reason I do not dare to push for a largely merge-based workflow. How to decompose into topical branches? - We realize that it would be awesome to assemble a finished integration from topic branches, but often work by our developers is not clearly defined (sometimes as simple as "poking around") and if some code has already gone into a "misc" topic, it can not be taken out of there again, according to the question above? How do you work with defining/approving/graduating/releasing your topic branches? Proper procedures like code review and graduating would of course be lovely, but we simply cannot keep things untangled enough to manage this - any suggestions? integration branches, illustration please? Vote and comment as much as you'd like, I'll try to keep the issue page clear and informative enough. Thanks! Below is a list of related topics on stackoverflow I have checked out: What are some good strategies to allow deployed applications to be hotfixable? Workflow description for git usage for in-house development Git workflow for corporate Linux kernel development How do you maintain development code and production code?

• Programmatically specifying Django model attributes

  - by mojbro

  Hi! I would like to add attributes to a Django models programmatically, at run time. For instance, lets say I have a Car model class and want to add one price attribute (database column) per currency, given a list of currencies. What is the best way to do this? I had an approach that I thought would work, but it didn't exactly. This is how I tried doing it, using the car example above: from django.db import models class Car(models.Model): name = models.CharField(max_length=50) currencies = ['EUR', 'USD'] for currency in currencies: Car.add_to_class('price_%s' % currency.lower(), models.IntegerField()) This does seem to work pretty well at first sight: $ ./manage.py syncdb Creating table shop_car $ ./manage.py dbshell shop=# \d shop_car Table "public.shop_car" Column | Type | Modifiers -----------+-----------------------+------------------------------------------------------- id | integer | not null default nextval('shop_car_id_seq'::regclass) name | character varying(50) | not null price_eur | integer | not null price_usd | integer | not null Indexes: "shop_car_pkey" PRIMARY KEY, btree (id) But when I try to create a new Car, it doesn't really work anymore: >>> from shop.models import Car >>> mycar = Car(name='VW Jetta', price_eur=100, price_usd=130) >>> mycar <Car: Car object> >>> mycar.save() Traceback (most recent call last): File "<console>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/base.py", line 410, in save self.save_base(force_insert=force_insert, force_update=force_update) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/base.py", line 495, in save_base result = manager._insert(values, return_id=update_pk) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/manager.py", line 177, in _insert return insert_query(self.model, values, **kwargs) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/query.py", line 1087, in insert_query return query.execute_sql(return_id) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/sql/subqueries.py", line 320, in execute_sql cursor = super(InsertQuery, self).execute_sql(None) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/sql/query.py", line 2369, in execute_sql cursor.execute(sql, params) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/backends/util.py", line 19, in execute return self.cursor.execute(sql, params) ProgrammingError: column "price_eur" specified more than once LINE 1: ...NTO "shop_car" ("name", "price_eur", "price_usd", "price_eur... ^

• Filtering a dropdown in Angular IE11 issue

  - by Brian S.

  I have a requirement for a select html element that can be duplicated multiple times on a page. The options for these select elements all come from a master list. All of the select elements can only show all of the items in the master list that have not been selected in any of the other select elements unless they just were duplicated. So I wrote a custom filter to do this in Angular and it seems to work just fine provided you are not using IE11. In IE when you select a new item from a duplicated select element, it seems to select the option after the one you selected even though the model still has the correct one set. I realize this sounds convoluted, so I created a jFiddle example. Using IE 11 try these steps: Select Bender Click the duplicate link Select Fry Notice that the one that is selected is Leela but the model still has Fry (id:2) as the one selected Now if you do the same thing in Chrome everything works as expected. Can anyone tell me how I might get around this or what I might be doing wrong? Here is the relevant Angular code: myapp.controller('Ctrl', function ($scope) { $scope.selectedIds = [{}]; $scope.allIds = [{ name: 'Bender', value: 1}, {name: 'Fry', value: 2}, {name: 'Leela', value: 3 }]; $scope.dupDropDown = function(currentDD) { var newDD = angular.copy(currentDD); $scope.selectedIds.push(newDD); } }); angular.module('appFilters',[]).filter('ddlFilter', function () { return function (allIds, currentItem, selectedIds) { //console.log(currentItem); var listToReturn = allIds.filter(function (anIdFromMasterList) { if (currentItem.id == anIdFromMasterList.value) return true; var areThereAny = selectedIds.some(function (aSelectedId) { return aSelectedId.id == anIdFromMasterList.value; }); return !areThereAny; }); return listToReturn; } }); And here is the relevant HTML <div ng-repeat="aSelection in selectedIds "> <a href="#" ng-click="dupDropDown(aSelection)">Duplicate</a> <select ng-model="aSelection.id" ng-options="a.value as a.name for a in allIds | ddlFilter:aSelection:selectedIds"> <option value="">--Select--</option> </select> </div>

• how to use SQL wildcard % with Queryset extra>select?

  - by tylias

  I'm trying to add weights to search terms I'm using to filter a queryset. Using the '%' wildcard is causing me some problems. I'm using the extra() modifier to add a weight parameter to the queryset, which I will be using to inform a sort ordering. (See http://docs.djangoproject.com/en/1.1/ref/models/querysets/#extra-select-none-where-none-params-none-tables-none-order-by-none-select-params-none ) Here's the gist of the code: def viewname(request) ... exact_matchstrings="" exact_matchstrings.append("(accountprofile.first_name LIKE '" + term + "')") exact_matchstrings.append("(accountprofile.first_name LIKE '" + term + '\%' + "')") extraquerystring = " + ".join(exact_matchstrings) return_queryset = return_queryset.extra( select = { 'match_weight': extraquerystring }, ) The effect I'm going for is that if the search term matches exactly, the weight associated with the record is 2, but if the term merely starts with the search term and isn't an exact match, the weight is 1. (for example, if 'term' = 'Jon', an entry with first_name='Jon' gets a weight of 2 but an entry with an entry with first_name = 'Jonathan' gets a weight of 1.) I can test the statement in SQL and it seems to work well enough. If I make this SQL query from the mysql shell, no problem: select (first_name like "Carl") + (first_name like "Car%") from accountprofile; But trying to run it via the extra() modifier in my view code and evaluating the resulting queryset gives me the following error: Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 68, in __repr__ data = list(self[:REPR_OUTPUT_SIZE + 1]) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 83, in __len__ self._result_cache.extend(list(self._iter)) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 238, in iterator for row in self.query.results_iter(): File "/usr/local/lib/python2.6/dist-packages/django/db/models/sql/query.py", line 287, in results_iter for rows in self.execute_sql(MULTI): File "/usr/local/lib/python2.6/dist-packages/django/db/models/sql/query.py", line 2369, in execute_sql cursor.execute(sql, params) File "/usr/local/lib/python2.6/dist-packages/django/db/backends/util.py", line 22, in execute sql = self.db.ops.last_executed_query(self.cursor, sql, params) File "/usr/local/lib/python2.6/dist-packages/django/db/backends/__init__.py", line 217, in last_executed_query return smart_unicode(sql) % u_params ValueError: unsupported format character ''' (0x27) at index 309 I've tried it escaping and not escaping % wildcard but that doesn't solve the problem. Doesn't seem to affect it at all, really. Any ideas?

• Django: CharField with fixed length, how?

  - by Giovanni Di Milia

  Hi everybody, I wold like to have in my model a CharField with fixed length. In other words I want that only a specified length is valid. I tried to do something like volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) but it gives me an error (it seems that I can use both max_length and min_length at the same time). Is there another quick way? Thanks EDIT: Following the suggestions of some people I will be a bit more specific: My model is this: class Volume(models.Model): vid = models.AutoField(primary_key=True) jid = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal") volumenumber = models.CharField('Volume Number') date_publication = models.CharField('Date of Publication', max_length=6, blank=True) class Meta: db_table = u'volume' verbose_name = "Volume" ordering = ['jid', 'volumenumber'] unique_together = ('jid', 'volumenumber') def __unicode__(self): return (str(self.jid) + ' - ' + str(self.volumenumber)) What I want is that the volumenumber must be exactly 4 characters. I.E. if someone insert '4b' django gives an error because it expects a string of 4 characters. So I tried with volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) but it gives me this error: Validating models... Unhandled exception in thread started by <function inner_run at 0x70feb0> Traceback (most recent call last): File "/Library/Python/2.5/site-packages/django/core/management/commands/runserver.py", line 48, in inner_run self.validate(display_num_errors=True) File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 249, in validate num_errors = get_validation_errors(s, app) File "/Library/Python/2.5/site-packages/django/core/management/validation.py", line 28, in get_validation_errors for (app_name, error) in get_app_errors().items(): File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 131, in get_app_errors self._populate() File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 58, in _populate self.load_app(app_name, True) File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 74, in load_app models = import_module('.models', app_name) File "/Library/Python/2.5/site-packages/django/utils/importlib.py", line 35, in import_module __import__(name) File "/Users/Giovanni/src/djangoTestSite/../djangoTestSite/journaldb/models.py", line 120, in <module> class Volume(models.Model): File "/Users/Giovanni/src/djangoTestSite/../djangoTestSite/journaldb/models.py", line 123, in Volume volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) TypeError: __init__() got an unexpected keyword argument 'min_length' That obviously doesn't appear if I use only "max_length" OR "min_length". I read the documentation on the django web site and it seems that I'm right (I cannot use both together) so I'm asking if there is another way to solve the problem. Thanks again

• Nested Sortable JQuery list doesn't work in IE while it does in FF

  - by Ben Fransen

  Hello everybody, While I'm using this site quite often as a resource for jQuery related problems I can't seem to find an answer this time. So here is my first post. During daytime at work I'm developing an informationsystem for generating MS Word documents. One of the modules I'm developing is for defining a default chapterselection for the table of contents and selecting texts by the given chapters. A user can submit new chapters and if necessary, add them as childchapter to a parent, flag them as 'adopt in TOC' and link a default text (from another module) to the chapter. My chapterlist is retreived recursively from a MySQL table and could look something like this: <ul class="sortableChapterlist"> <li>1</li> <li>2 <ul class="sortableChapterlist"> <li>2.1</li> <li>2.2</li> <li>2.3 <ul class="sortableChapterlist"> <li>2.3.1</li> <li>2.3.2</li> </ul> </li> </ul> </li> </ul> In FireFox the code works like a charm but IE (7) doesn't seem to like it that much. I'm only able to correctly drag arround the mainchapters. When attempting to drag a subchapter, no matter it's level, the correspondending mainchapter lifts up with some child, never all. This is the jQuery code I'm using to accomplish the task: $(function(){ $(".sortableChapterlist").sortable({ opacity: 0.7, helper: 'clone', cursor: 'move' }); $(".sortableChapterlist").selectable(); $(".sortableChapterlist").disableSelection(); }); Does anybody have some ideas about this? I'm guessing IE kinda falls over the multiple class reference "chapter_list" in combination with jQuery trying to handle the draggable/sortable. Kinds regards from Holland, Ben Fransen

• oci_connect Blank Page in PHP

  - by Bryan

  UPDATE (3/8/2010) I installed Xdebug and have it tracing my code. This is the output I am getting: TRACE START [2010-03-08 17:53:05] 0.2090 327864 -> {main}() /data/aims3/http/octest.php:0 0.2091 327988 -> ini_set(string(14), string(1)) /data/aims3/http/octest.php:3 0.2093 327920 -> error_reporting(long) /data/aims3/http/octest.php:4 0.2094 328048 -> oci_connect(string(8), string(8), string(25)) /data/aims3/http/octest.php:6 The trace halts at that point. I have installed everything the same way on a local server and it works fine. To say I am at a complete loss would be putting it lightly. *NOTE: I ran make test and it returned FAIL on every test. I never ran this on my working machine to see if it reports the same errors. Any idea why make test would report FAIL but make doesn't report any error? I've installed the Oracle Instantclient with no reported errors along with the OCI8 PECL package and at a loss. Whenever I try to open a connection with oci_connect, it halts my entire PHP script. EXAMPLE: <?php ini_set ("display_errors", "1"); error_reporting(E_ALL); echo "before"; $conn = oci_connect("username", "password", "host"); echo "after"; ?> Returns a complete blank page. The module is loaded (seen in phpinfo) and everything installed with no errors. I am at a complete loss. CentOS: 5.4 Apache: 2.2.3 PHP: 5.3.1 InstantClient: 11.2 oci8: 1.4.1 Any thoughts? NOTES Apache Error Log reports nothing Attempted Debugging: 1: <?php ini_set ("display_errors", "1"); error_reporting(E_ALL); echo "before"; if(!function_exists('oci_connect')) die('Oracle Not Installed'); echo "after"; ?> Returns: beforeafter 2: Changing host to //host Returns: Same error

• Jruby Gems-in-a-jar issue

  - by antonio

  Hi all, I am trying to write some code in ruby (using jruby) to be compiled to java bytecode with jrubyc and deployed to a remote machine where it will be run on the JVM (no ruby available there). Everything works fine as long as I am happy to stick with the standard jruby library. As explained on the jruby website, I simply copy the jruby-complete.jar library to the remote machine and include it in the classpath at runtime. I fire my compiled script and it works: cool! The problems start when I need some other libraries (typically rubygems) to run my script. I am aware of cool stuff like rawr, -which I successfully tested- to put together all you need in a single package. However that is not the solution I am looking for: I will have many small scripts to run independently and I don't want each of them to grow to at least 10 MB just because I insanely include the jruby-complete.jar in each of them. What I would like is to compile a .jar for each of the libraries that I will need to use, put all of them in a common folder on the remote machine and include them at runtime in the classpath when I run my compiled jruby scripts on the JVM. This said, I tried to follow the instructions here: http://blog.nicksieger.com/articles/2009/01/10/jruby-1-1-6-gems-in-a-jar I tried exactly the example shown there, with the "chronic" gem. Going step by step: Install the gem locally: java -jar jruby-complete-1.1.6.jar -S gem install -i ./chronic chronic --no-rdoc --no-ri Package it into a jar: jar cf chronic.jar -C chronic . Write a two lines test script, saving it as testt.rb: require 'chronic' Chronic.parse('tomorrow') Compile with: jrubyc testt.rb Run the resulting java class testt.class with the following (having both jruby-complete.jar and chronic.jar in the same folder as the java class): java -cp .:/jruby-complete.jar:./chronic.jar testt I get the following error: Exception in thread "main" file:/Users/ave2/NetBeansProjects/jrubywatir/lib/jruby-complete.jar!/METAINF/jruby.home/lib/ruby/site_ruby/shared/builtin/core_ext/symbol.rb:1:in `const_missing': uninitialized constant Chronic (NameError) from testt.rb:2 ...internal jruby stack elided... from Module.const_missing(testt.rb:2) from (unknown).(unknown)(:1) I really don't understand what I am doing wrong, and I am totally stuck on this. I am a noob in Ruby, much more used to Python: don't miss a chance to convert an infidel! :-) Thanks.

• Haskell newbie on types

  - by garulfo

  I'm completely new to Haskell (and more generally to functional programming), so forgive me if this is really basic stuff. To get more than a taste, I try to implement in Haskell some algorithmic stuff I'm working on. I have a simple module Interval that implements intervals on the line. It contains the type data Interval t = Interval t t the helper function makeInterval :: (Ord t) => t -> t -> Interval t makeInterval l r | l <= r = Interval l r | otherwise = error "bad interval" and some utility functions about intervals. Here, my interest lies in multidimensional intervals (d-intervals), those objects that are composed of d intervals. I want to separately consider d-intervals that are the union of d disjoint intervals on the line (multiple interval) from those that are the union of d interval on d separate lines (track interval). With distinct algorithmic treatments in mind, I think it would be nice to have two distinct types (even if both are lists of intervals here) such as import qualified Interval as I -- Multilple interval newtype MInterval t = MInterval [I.Interval t] -- Track interval newtype TInterval t = TInterval [I.Interval t] to allow for distinct sanity checks, e.g. makeMInterval :: (Ord t) => [I.Interval t] -> MInterval t makeMInterval is = if foldr (&&) True [I.precedes i i' | (i, i') <- zip is (tail is)] then (MInterval is) else error "bad multiple interval" makeTInterval :: (Ord t) => [I.Interval t] -> TInterval t makeTInterval = TInterval I now get to the point, at last! But some functions are naturally concerned with both multiple intervals and track intervals. For example, a function order would return the number of intervals in a multiple interval or a track interval. What can I do? Adding -- Dimensional interval data DInterval t = MIntervalStuff (MInterval t) | TIntervalStuff (TInterval t) does not help much, since, if I understand well (correct me if I'm wrong), I would have to write order :: DInterval t -> Int order (MIntervalStuff (MInterval is)) = length is order (TIntervalStuff (TInterval is)) = length is and call order as order (MIntervalStuff is) or order (TIntervalStuff is) when is is a MInterval or a TInterval. Not that great, it looks odd. Neither I want to duplicate the function (I have many functions that are concerned with both multiple and track intevals, and some other d-interval definitions such as equal length multiple and track intervals). I'm left with the feeling that I'm completely wrong and have missed some important point about types in Haskell (and/or can't forget enough here about OO programming). So, quite a newbie question, what would be the best way in Haskell to deal with such a situation? Do I have to forget about introducing MInterval and TInterval and go with one type only? Thanks a lot for your help, Garulfo

• Proxy settings with ivy...

  Hi, I have an issue where in I have defined dependancies in ivy.xml on our internal corporate svn. I am able to access this svn site without any proxy task in ant. While my dependencies resides on ibiblio, that’s something outside our corporate, and needs proxy inorder to download something.

I don’t need proxy while getting ivy.xml (as if I have proxy, ivy wont be able to find ivy file behind proxy from within the network), and I just need it when my resolver goes to public url.

• Gwt-gdata authentication

  - by Raffo

  Hi guys, I'm writing an application with GWT and I found on the internet that there's a library to use easily gdata features. In particular I need to use the integration with Google Calendar. I followed the official guide on gwt-gdata site to do the authentication ( http://code.google.com/p/gwt-gdata/wiki/GettingStarted ) but unfortunately, I got an error. This is the error: 17:59:12.463 [ERROR] [testmappa] Unable to load module entry point class testMappa.client.TestMappa (see associated exception for details) com.google.gwt.core.client.JavaScriptException: (TypeError): $wnd.google.accounts is undefined fileName: http://127.0.0.1:8888 lineNumber: 29 stack: ("http://www.google.com/calendar/feeds/")@http://127.0.0.1:8888:29 connect("http://127.0.0.1:8888/TestMappa.html?gwt.codesvr=127.0.0.1:9997","`gL1<a3s4B&Y{(Ci","127.0.0.1:9997","testmappa","2.0")@:0 ((void 0),"testmappa","http://127.0.0.1:8888/testmappa/")@http://127.0.0.1:8888/testmappa/hosted.html?testmappa:264 z()@http://127.0.0.1:8888/testmappa/testmappa.nocache.js:2 (-2)@http://127.0.0.1:8888/testmappa/testmappa.nocache.js:8 at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:195) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:120) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:507) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:264) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91) at com.google.gwt.accounts.client.User.login(User.java) at testMappa.client.TestMappa.onModuleLoad(TestMappa.java:68) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.ModuleSpace.onLoad(ModuleSpace.java:369) at com.google.gwt.dev.shell.OophmSessionHandler.loadModule(OophmSessionHandler.java:185) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:380) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:222) at java.lang.Thread.run(Thread.java:637) I'm not able to understand the reason of this error. My code is simply: String scope = "http://www.google.com/calendar/feeds/"; User.login(scope); And as far as I know it should work as it is. I don't know what to do and I'm here to ask how to solve this problem and if I can directly use gdata native java library, but I believe this other thing is not possible to be done for client-side gwt code (since the code is going to be converted to javascript). Thank you.

• F# Add Constructor to a Record?

  - by akaphenom

  Basically I want to have a single construct to deal with serializing to both JSON and formatted xml. Records workd nicley for serializing to/from json. However XmlSerializer requires a parameterless construtor. I don't really want to have to go through the exercise of building class objects for these constructs (principal only). I was hoping there could be some shortcut for getting a parameterless constructor onto a record (perhaps with a wioth statement or something). I can't get it to behave - has anybody in the community had any luck? module JSONExample open System open System.IO open System.Net open System.Text open System.Web open System.Xml open System.Security.Authentication open System.Runtime.Serialization //add assemnbly reference System.Runtime.Serialization System.Xml open System.Xml.Serialization open System.Collections.Generic [<DataContract>] type ChemicalElementRecord = { [<XmlAttribute("name")>] [<field: DataMember(Name="name") >] Name:string [<XmlAttribute("name")>] [<field: DataMember(Name="boiling_point") >] BoilingPoint:string [<XmlAttribute("atomic-mass")>] [<field: DataMember(Name="atomic_mass") >] AtomicMass:string } [<XmlRoot("freebase")>] [<DataContract>] type FreebaseResultRecord = { [<XmlAttribute("code")>] [<field: DataMember(Name="code") >] Code:string [<XmlArrayAttribute("results")>] [<XmlArrayItem(typeof<ChemicalElementRecord>, ElementName = "chemical-element")>] [<field: DataMember(Name="result") >] Result: ChemicalElementRecord array [<XmlElement("message")>] [<field: DataMember(Name="message") >] Message:string } let getJsonFromWeb() = let query = "[{'type':'/chemistry/chemical_element','name':null,'boiling_point':null,'atomic_mass':null}]" let query = query.Replace("'","\"") let queryUrl = sprintf "http://api.freebase.com/api/service/mqlread?query=%s" "{\"query\":"+query+"}" let request : HttpWebRequest = downcast WebRequest.Create(queryUrl) request.Method <- "GET" request.ContentType <- "application/x-www-form-urlencoded" let response = request.GetResponse() let result = try use reader = new StreamReader(response.GetResponseStream()) reader.ReadToEnd(); finally response.Close() let data = Encoding.Unicode.GetBytes(result); let stream = new MemoryStream() stream.Write(data, 0, data.Length); stream.Position <- 0L stream let test = // get some JSON from the web let stream = getJsonFromWeb() // convert the stream of JSON into an F# Record let JsonSerializer = Json.DataContractJsonSerializer(typeof<FreebaseResultRecord>) let result: FreebaseResultRecord = downcast JsonSerializer.ReadObject(stream) // save the Records to disk as JSON use fs = new FileStream(@"C:\temp\freebase.json", FileMode.Create) JsonSerializer.WriteObject(fs,result) fs.Close() // save the Records to disk as System Controlled XML let xmlSerializer = DataContractSerializer(typeof<FreebaseResultRecord>); use fs = new FileStream(@"C:\temp\freebase.xml", FileMode.Create) xmlSerializer.WriteObject(fs,result) fs.Close() use fs = new FileStream(@"C:\temp\freebase-pretty.xml", FileMode.Create) let xmlSerializer = XmlSerializer(typeof<FreebaseResultRecord>) xmlSerializer.Serialize(fs,result) fs.Close() ignore(test)

• Reproduce PIPE functionality in IronPython

  - by Muppet Geoff

  Hi, I am hoping some genious out there can help me out with this... I am using sox to merge and resample a group of WAV files, and pipe the output directly to the input of NeroAACEnc for encoding to AAC format. I originally ran the process in a script, which included: sox.exe d:\audio\1.wav d:\audio\2.wav d:\audio\3.wav -c 1 -r 22050 -t wav - | neroAacEnc.exe -q 0.5 -if - -of test.m4a This worked as expected. The '-' in the comand line translates as 'Pipe/redirect input/output (stdin/stdout)' - So Sox pipes to stdout, and NeroAACEnc reads from stdin, the | joins them together. I then migrated the whole solution to Python, and the equivalent command became: from subprocess import call, Popen, PIPE runwav = Popen(['sox.exe', 'd:\audio\1.wav', 'd:\audio\2.wav', 'd:\audio\3.wav', '-c', '1', '-r', '22050', '-t', 'wav', '-'], shell=False, stdout=PIPE) runm4b = call(['neroAacEnc.exe', '-q', '0.5', '-if', '-', '-of', 'test.m4a'], shell=False, stdin=runwav.stdout) This also worked like a charm, exactly as expected. Slightly more convoluted, but hey :) Well now I have to move it to IronPython, and the Subprocess module isn't available (the partial implementation that is, doesn't have Popen/PIPE support - plus it seems silly to add a custom library when there is probably a native alternative). I should mention here, that I opted for IronPython over C#, because I am comfortable with Python now - however, there is a chance of moving it again later to C# native, and I am using IronPython to ease myself into it :) I have no C# or .net experience. So far I have the following equivalent, that sets up the 2 processes: from System.Diagnostics import Process wav = Process() wav.StartInfo.UseShellExecute = False wav.StartInfo.RedirectStandardOutput = True wav.StartInfo.FileName = 'sox.exe' wav.StartInfo.Arguments = 'd:\audio\1.wav d:\audio\2.wav d:\audio\3.wav -c 1 -r 22050 -t wav -' wav.Start() m4b = Process() m4b.StartInfo.UseShellExecute = False m4b.StartInfo.RedirectStandardInput = True m4b.StartInfo.FileName = 'neroAacEnc.exe' m4b.StartInfo.Arguments = '-q 0.5 -if - -of test.m4a' m4b.Start() I know that these 2 processes start (I can see Nero and Sox in the task manager) but what I can't figure out (for the life of me) is how to string the two output/input streams together, as with the previous two solutions. I have searched and searched, so I thought I'd ask! If anyone knows either: How to join the two streams with the same net result as the Python and Commandline versions; or A better way to acheive what I am trying to do. I would be extremely grateful! Many thanks in advance, Geoff P.S. A code sample based off the above would be awesome :) or a specific code example of a similar process that I can easily translate... this has broked my brayne.

• How to disable Mac OS X from using swap when there still is "Inactive" memory?

  - by Motin

  A common phenomena in my day to day usage (and several other's according to various posts throughout the internet) of OS X, the system seems to become slow whenever there is no more "Free" memory available. Supposedly, this is due to swapping, since heavy disk activity is apparent and that vm_stat reports many pageouts. (Correct me from wrong) However, the amount of "Inactive" ram is typically around 12.5%-25% of all available memory (^1.) when swapping starts/occurs/ends. According to http://support.apple.com/kb/ht1342 : Inactive memory This information in memory is not actively being used, but was recently used. For example, if you've been using Mail and then quit it, the RAM that Mail was using is marked as Inactive memory. This Inactive memory is available for use by another application, just like Free memory. However, if you open Mail before its Inactive memory is used by a different application, Mail will open quicker because its Inactive memory is converted to Active memory, instead of loading Mail from the slower hard disk. And according to http://developer.apple.com/library/mac/#documentation/Performance/Conceptual/ManagingMemory/Articles/AboutMemory.html : The inactive list contains pages that are currently resident in physical memory but have not been accessed recently. These pages contain valid data but may be released from memory at any time. So, basically: When a program has quit, it's memory becomes marked as Inactive and should be claimable at any time. Still, OS X will prefer to start swapping out memory to the Swap file instead of just claiming this memory, whenever the "Free" memory gets to low. Why? What is the advantage of this behavior over, say, instantly releasing Inactive memory and not even touch the swap file? Some sources (^2.) indicate that OS X would page out the "Inactive" memory to swap before releasing it, but that doesn't make sense now does it if the memory may be released from memory at any time? Swapping is expensive, releasing is cheap, right? Can this behavior be changed using some preference or known hack? (Preferably one that doesn't include disabling swap/dynamic_pager altogether and restarting...) I do appreciate the purge command, as well as the concept of Repairing disk permissions to force some Free memory, but those are ways to painfully force more Free memory than to actually fixing the swap/release decision logic... Btw a similar question was asked here: http://forums.macnn.com/90/mac-os-x/434650/why-does-os-x-swap-when/ and here: http://hintsforums.macworld.com/showthread.php?t=87688 but even though the OPs re-asked the core question, none of the replies addresses an answer to it... ^1. UPDATE 17-mar-2012 Since I first posted this question, I have gone from 4gb to 8gb of installed ram, and the problem remains. The amount of "Inactive" ram was 0.5gb-1.0gb before and is now typically around 1.0-2.0GB when swapping starts/occurs/ends, ie it seems that around 12.5%-25% of the ram is preserved as Inactive by osx kernel logic. ^2. For instance http://apple.stackexchange.com/questions/4288/what-does-it-mean-if-i-have-lots-of-inactive-memory-at-the-end-of-a-work-day : Once all your memory is used (free memory is 0), the OS will write out inactive memory to the swapfile to make more room in active memory. UPDATE 17-mar-2012 Here is a round-up of the methods that have been suggested to help so far: The purge command "Used to approximate initial boot conditions with a cold disk buffer cache for performance analysis. It does not affect anonymous memory that has been allocated through malloc, vm_allocate, etc". This is useful to prevent osx to swap-out the disk cache (which is ridiculous that osx actually does so in the first place), but with the downside that the disk cache is released, meaning that if the disk cache was not about to be swapped out, one would simply end up with a cold disk buffer cache, probably affecting performance negatively. The FreeMemory app and/or Repairing disk permissions to force some Free memory Doesn't help releasing any memory, only moving some gigabytes of memory contents from ram to the hd. In the end, this causes lots of swap-ins when I attempt to use the applications that were open while freeing memory, as a lot of its vm is now on swap. Speeding up swap-allocation using dynamicpagerwrapper Seems a good thing to do in order to speed up swap-usage, but does not address the problem of osx swapping in the first place while there is still inactive memory. Disabling swap by disabling dynamicpager and restarting This will force osx not to use swap to the price of the system hanging when all memory is used. Not a viable alternative... Disabling swap using a hacked dynamicpager Similar to disabling dynamicpager above, some excerpts from the comments to the blog post indicate that this is not a viable solution: "The Inactive Memory is high as usual". "when your system is running out of memory, the whole os hangs...", "if you consume the whole amount of memory of the mac, the machine will likely hang" To sum up, I am still unaware of a way of disabling Mac OS X from using swap when there still is "Inactive" memory. If it isn't possible, maybe at least there is an explanation somewhere of why osx prefers to swap out memory that may be released from memory at any time?

• iptables to allow 80 and 443 on chillispot running ddwrt

  - by user76682

  I am having problems setting this up. this is what I am trying to do. I have Chillispot (hotpsot) running on dd-wrt. Everything is setup, but the client wants only 80 and 443 to go through through the hotspot. I found this tutorial for dd-wrt but that doesnt seem to work. http://www.dd-wrt.com/wiki/index.php/Iptables#Allow_HTTP_traffic_only_to_specific_domain.28s.29 Initially I tried to place the options at the top but didnt work. then i flushed the iptables and set only these three.

• WSIT, Maven, and wsimport -- Can They Work Together?

  - by rtperson

  Hi all, I'm working on a small-ish multi-module project in Maven. We've separated the UI from the database layer using Web Services, and thanks to the jaxws-maven-plugin, the creation of the WSDL and WS client are more or less handled for us. (The plugin is essentially a wrapper around wsgen and wsimport.) So far so good. The problem comes when I try to layer WSIT security into the picture. NetBeans allows me to generate the security metadata easily, but wsimport seems completely incapable of dealing with anything beyond a Basic-auth level of security. Here's our current, insecure way of calling wsimport during a Maven build: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>jaxws-maven-plugin</artifactId> <version>1.10</version> <executions> <execution> <goals> <goal>wsimport</goal> </goals> <configuration> <wsdlUrls> <wsdlUrl>${basedir}/../WebService/target/jaxws/wsgen/wsdl/WebService.wsdl</wsdlUrl> </wsdlUrls> <packageName>com.yourcompany.appname.ws.client</packageName> <sourceDestDir>${basedir}/src/main/java</sourceDestDir> <destDir>${basedir}/target/jaxws</destDir> </configuration> </execution> </executions> </plugin> I have tried playing around with xauthFile, xadditionalHeaders, passing javax.xml.ws.security.auth.username and password through args. I have also tried using wsimport from the command line to point to the Tomcat-generated WSDL, which has the additional security info. Nothing, however, seems to change the composition of the wsimport-generated files at all. So I guess my question here is, to get a WSIT-compliant client, am I stuck abandoning Maven and the jaxws plugin altogether? Is there a way to get a WSIT client to auto-generate? Or will I need to generate the client by hand? Let me know if you need any additional info beyond what I've written here. I'm deploying to Tomcat, although that doesn't seem to be an issue, as Maven seems happy to pull Metro into the deployed WAR file. Thanks in advance!

• Installing PyGraphViz on Windows, Python 2.7

  - by user574043

  I can't install pygraphviz on Windows XP. I'm using Python27.

• Haskell: how to get through 'no instance for' ?

  - by artemave

  I am learning Haskell. I am on the 8th chapter of this book. The main thing I've learned so far is that Haskell is very unfriendly to me and it bites my ass where possible. Moreover... Heck! Enough mourning, to business. Here is the code: module GlobRegex ( globToRegex, matchesGlob ) where import Text.Regex.Posix import Text.Regex.Posix.String import Text.Regex.Base.RegexLike data CaseOpt = Case | NoCase deriving (Eq) matchesGlob :: String -> String -> CaseOpt -> Bool matchesGlob name pat caseopt = match regex name where regex = case caseopt of NoCase -> makeRegexOpts (defaultCompOpt + compIgnoreCase) defaultExecOpt (globToRegex pat) Case -> makeRegex (globToRegex pat) globToRegex :: String -> String ... And here is how it fails to compile: Prelude Text.Regex.Posix Text.Regex.Base.RegexLike> :load globtoregex\GlobRegex. hs [1 of 1] Compiling GlobRegex ( globtoregex\GlobRegex.hs, interpreted ) globtoregex\GlobRegex.hs:14:31: No instance for (RegexLike regex [Char]) arising from a use of `match' at globtoregex\GlobRegex.hs:14:31-46 Possible fix: add an instance declaration for (RegexLike regex [Char]) In the expression: match regex name In the definition of `matchesGlob': matchesGlob name pat caseopt = match regex name where regex = case caseopt of { NoCase -> makeRegexOpts (defaultCompOpt + compIgnoreCase) defaultExecOpt (globToRegex pat) Case -> makeRegex (globToRegex pat) } globtoregex\GlobRegex.hs:17:23: No instance for (RegexMaker regex CompOption execOpt String) arising from a use of `makeRegex' at globtoregex\GlobRegex.hs:17:23-49 Possible fix: add an instance declaration for (RegexMaker regex CompOption execOpt String) In the expression: makeRegex (globToRegex pat) In a case alternative: Case -> makeRegex (globToRegex pat) In the expression: case caseopt of { NoCase -> makeRegexOpts (defaultCompOpt + compIgnoreCase) defaultExecOpt (globToRegex p at) Case -> makeRegex (globToRegex pat) } Failed, modules loaded: none. To my best understanding, Text.Regex.Posix.String provides instances for RegexLike Regex String and RegexMaker Regex CompOption ExecOption String, so it should work. On the other hand, I can see that regex in the error message is type variable, not a concrete type, so, perhaps not... Anyway, this is where I am stuck. May be there is a common pattern for resolving no instance for type of problems? Or, in Haskell terms, instance of SmartGuess typeclass for no instance for?

• Proper network configuration for a KVM guest to be on the same networks at the host

  - by Steve Madsen

  I am running a Debian Linux server on Lenny. Within it, I am running another Lenny instance using KVM. Both servers are externally available, with public IPs, as well as a second interface with private IPs for the LAN. Everything works fine, except the VM sees all network traffic as originating from the host server. I suspect this might have something to do with the iptables-based firewall I'm running on the host. What I'd like to figure out is: how to I properly configure the host's networking such that all of these requirements are met? Both host and VMs have 2 network interfaces (public and private). Both host and VMs can be independently firewalled. Ideally, VM traffic does not have to traverse the host firewall. VMs see real remote IP addresses, not the host's. Currently, the host's network interfaces are configured as bridges. eth0 and eth1 do not have IP addresses assigned to them, but br0 and br1 do. /etc/network/interfaces on the host: # The primary network interface auto br1 iface br1 inet static address 24.123.138.34 netmask 255.255.255.248 network 24.123.138.32 broadcast 24.123.138.39 gateway 24.123.138.33 bridge_ports eth1 bridge_stp off auto br1:0 iface br1:0 inet static address 24.123.138.36 netmask 255.255.255.248 network 24.123.138.32 broadcast 24.123.138.39 # Internal network auto br0 iface br0 inet static address 192.168.1.1 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 bridge_ports eth0 bridge_stp off This is the libvirt/qemu configuration file for the VM: <domain type='kvm'> <name>apps</name> <uuid>636b6620-0949-bc88-3197-37153b88772e</uuid> <memory>393216</memory> <currentMemory>393216</currentMemory> <vcpu>1</vcpu> <os> <type arch='i686' machine='pc'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='cdrom'> <target dev='hdc' bus='ide'/> <readonly/> </disk> <disk type='file' device='disk'> <source file='/raid/kvm-images/apps.qcow2'/> <target dev='vda' bus='virtio'/> </disk> <interface type='bridge'> <mac address='54:52:00:27:5e:02'/> <source bridge='br0'/> <model type='virtio'/> </interface> <interface type='bridge'> <mac address='54:52:00:40:cc:7f'/> <source bridge='br1'/> <model type='virtio'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> </devices> </domain> Along with the rest of my firewall rules, the firewalling script includes this command to pass packets destined for a KVM guest: # Allow bridged packets to pass (for KVM guests). iptables -A FORWARD -m physdev --physdev-is-bridged -j ACCEPT (Not applicable to this question, but a side-effect of my bridging configuration appears to be that I can't ever shut down cleanly. The kernel eventually tells me "unregister_netdevice: waiting for br1 to become free" and I have to hard reset the system. Maybe a sign I've done something dumb?)

• RAID1 rebuild fails due to disk errors

  - by overlord_tm

  Quick info: Dell R410 with 2x500GB drives in RAID1 on H700 Adapter Recently one of drives in RAID1 array on server failed, lets call it Drive 0. RAID controller marked it as fault and put it offline. I replaced faulty disk with new one (same series and manufacturer, just bigger) and configured new disk as hot spare. Rebuild from Drive1 started immediately and after 1.5 hour I got message that Drive 1 failed. Server was unresponsive (kernel panic) and required reboot. Given that half hour before this error rebuild was at about 40%, I estimated that new drive is not in sync yet and tried to reboot just with Drive 1. RAID controller complained a bit about missing RAID arrays, but it found foreign RAID array on Drive 1 and I imported it. Server booted and it runs (from degraded RAID). Here is SMART data for disks.

• Does weak typing offer any advantages?

  - by sub

  Don't confuse this with static vs. dynamic typing! You all know JavaScripts/PHPs infamous type systems: PHP example: echo "123abc"+2; // 125 - the reason for this is explained // in the PHP docs but still: This hurts echo "4"+1; // 5 - Oh please echo "ABC"*5; // 0 - WTF // That's too much, seriously now. // This here might be actually a use for weak typing, but no - // it has to output garbage. JavaScript example: // A good old JavaScript, maybe you'll do better? alert("4"+1); // 51 - Oh come on. alert("abc"*3); // NaN - What the... // Have your creators ever heard of the word "consistence"? Python example: # Python's type system is actually a mix # It spits errors on senseless things like the first example below AND # allows intelligent actions like the second example. >>> print("abc"+1) Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> print("abc"+1) TypeError: Can't convert 'int' object to str implicitly >>> print("abc"*5) abcabcabcabcabc Ruby example: puts 4+"1" // Type error - as supposed puts "abc"*4 // abcabcabcabc - makes sense After these examples it should be clear that PHP/JavaScript probably have the most inconsistent type systems out there. This is a fact and really not subjective. Now when having a closer look at the type systems of Ruby and Python it seems like they are having a much more intelligent and consistent type system. I think these examples weren't really necessary as we all know that PHP/JavaScript have a weak and Python/Ruby have a strong type system. I just wanted to mention why I'm asking this. Now I have two questions: When looking at those examples, what are the advantages of PHPs and JavaScripts type systems? I can only find downsides: They are inconsistent and I think we know that this is not good Types conversions are hardly controllable Bugs are more likely to happen and much harder to spot Do you prefer one of the both systems? Why? Personally I have worked with PHP, JavaScript and Python so far and must say that Pythons type system has really only advantages over PHPs and JavaScripts. Does anybody here not think so? Why then?

• Moose::Error::Croak error reporting not from perspective of caller.

  - by crashpoint_zero

  I just recently started out on Moose and its a great OO framework not only to use but also to learn new OO concepts. One of the things I wanted to do was to do error reporting from perspective of caller during object creation. I saw that Moose has the module Moose::Error::Croak which tells Moose to override the default error reporting by croak call. I used it but it did not seem to help Moose code - Foo.pm package Foo; use metaclass ( metaclass => 'Moose::Meta::Class', error_class => 'Moose::Error::Croak', ); use Moose; has 'attr1' => ( is => 'rw', isa => 'Str', required => '1', ); no Moose; 1; Moose code - fooser.pl #!/usr/bin/perl use strict; use warnings; use Foo; my $foobj = Foo->new(); This fails with error: Attribute (attr1) is required at /usr/local/lib/perl/5.8.8/Class/MOP/Class.pm line 364 which is terse than the actual stack trace if Moose::Error::Croak is not used. But it does not report it from perspective of caller. If this were a Perl 5 OO code and I had Foo.pm as: package Foo; use strict; use warnings; use Carp; sub new { my ($class, %args) = @_; my $self = {}; if (! exists $args{'attr1'}) { croak "ERR: did not provide attr1"; } $self->{'attr1'} = $args{attr1}; bless $self, $class; return $self; } 1; And if fooser.pl was executed I would have got the error: "ERR: did not provide attr1 at fooser.pl line 6" which is from the perspective of the caller as it points to line no. 6 of fooser.pl rather than MOP.pm's line no. 364. How can I do this in Moose? Or am I misunderstanding something here?

• Django & google openid authentication with socialauth

  - by Zayatzz

  Hello I am trying to use django-socialauth (http://github.com/uswaretech/Django-Socialauth) for authenticating users for my django project. This is firs time working with openid and i've had to figure out how exactly this open id works. I have more or less understood it, by now, but there are few things that elude me. The authentication process starts when the request is put together in in django-socialauth.openid_consumer.views.begin. I can see that the outgoing authentication request is more or less something like this: https://www.google.com/accounts/o8/ud?openid.assoc_handle=AOQobUckRThPUj3K1byG280Aze-dnfc9Iu6AEYaBwvHE11G0zy8kY8GZ& openid.ax.if_available=fname& openid.ax.mode=fetch_request& openid.ax.required=email& openid.ax.type.email=http://axschema.org/contact/email& openid.ax.type.fname=http://example.com/schema/fullname& openid.claimed_id=http://specs.openid.net/auth/2.0/identifier_select& openid.identity=http://specs.openid.net/auth/2.0/identifier_select& openid.mode=checkid_setup&openid.ns=http://specs.openid.net/auth/2.0& openid.ns.ax=http://openid.net/srv/ax/1.0& openid.ns.sreg=http://openid.net/extensions/sreg/1.1& openid.realm=http://localhost/& openid.return_to=http://localhost/social/gmail_login/complete/?janrain_nonce=2010-03-20T11%3A19%3A44ZPZCjNc&openid.sreg.optional=postcode,country,nickname,email This is lot like 2nd example here: http://code.google.com/apis/accounts/docs/OpenID.html#Samples The problem is, that the request, i get back, is nothing like the corresponding example from code.google.com (look at the 3rd example in example responses. Response dict i get is like this: { 'openid.op_endpoint': 'https://www.google.com/accounts/o8/ud', 'openid.sig': 'QWMa4x4ruMUvSCfLwKV6CZRuo0E=', 'openid.ext1.type.email': 'http://axschema.org/contact/email', 'openid.return_to': 'http://localhost/social/gmail_login/complete/?janrain_nonce=2010-03-20T17%3A54%3A06ZHV4cqh', 'janrain_nonce': '2010-03-20T17:54:06ZHV4cqh', 'openid.response_nonce': '2010-03-20T17:54:06ZdC5mMu9M_6O4pw', 'openid.claimed_id': 'https://www.google.com/accounts/o8/id?id=AItOghawkFz0aNzk91vaQWhD-DxRJo6sS09RwM3SE', 'openid.mode': 'id_res', 'openid.ns.ext1': 'http://openid.net/srv/ax/1.0', 'openid.signed': 'op_endpoint,claimed_id,identity,return_to,response_nonce,assoc_handle,ns.ext1,ext1.mode,ext1.type.email,ext1.value.email', 'openid.ext1.value.email': '[email protected]', 'openid.assoc_handle': 'AOQobUfssTJ2IxRlxrIvU4Xg8HHQKKTEuqwGxvwwuPR5rNvag0elGlYL', 'openid.ns': 'http://specs.openid.net/auth/2.0', 'openid.identity': 'https://www.google.com/accounts/o8/id?id=AItOawkghgfhf1FkvaQWhD-DxRJo6sS09RwMKjASE', 'openid.ext1.mode': 'fetch_response'} The socialauth itself has been built to accept my email address this way: elif request.openid and request.openid.ax: email = request.openid.ax.get('email') And obviously this fails. Why i am asking all this is, that perhaps i am doing something wrong and my outgoing request is wrong? Or am i doing all correctly and should change the socialaouth module to accept info in a new way and then commit the change? Alan
