  • How do I generate coverage xml report for a single package?

    - by Wraith
    I'm using nose and coverage to generate coverage reports. I only have one package right now, ae, so I specify to only cover that: nosetests -w tests/unit --with-xunit --with-coverage --cover-package=ae And here are the results, which look good: Name Stmts Exec Cover Missing ---------------------------------------------- ae 1 1 100% ae.util 253 224 88% 39, 63-65, 284, 287, 362, 406 ---------------------------------------------- TOTAL 263 234 88% ---------------------------------------------------------------------- Ran 68 tests in 5.292s However when I run coverage xml, coverage pulls in more packages than necessary, including python email and logging packages which have nothing to do with my code. If I run coverage xml ae, I get this error: No source for code: '/home/wraith/dev/projects/trimurti/src/ae': [Errno 21] Is a directory: '/home/wraith/dev/projects/trimurti/src/ae' Is there a way to generate the XML for just the ae package?

  • How to populate List<string> with Datarow values from single columns...

    - by James
    Hi, I'm still learning (baby steps). Messing about with a function and hoping to find a tidier way to deal with my datatables. For the more commonly used tables throughout the life of the program, I'll dump them to datatables and query those instead. What I'm hoping to do is query the datatables for say column x = "this", and convert the values of column "y" directly to a List to return to the caller: private List<string> LookupColumnY(string hex) { List<string> stringlist = new List<string>(); DataRow[] rows = tblDataTable.Select("Columnx = '" + hex + "'", "Columny ASC"); foreach (DataRow row in rows) { stringlist.Add(row["Columny"].ToString()); } return stringlist; } Anyone know a slightly simpler method? I guess this is easy enough, but I'm wondering if I do enough of these if iterating via foreach loop won't be a performance hit. TIA!

  • Terminal / Panel PC - Single Server Solution: Client/Server or RDP?

    - by StillLearning
    Hi, Our current setup involves a touch screen panel pc with embedded windows, that is connected via network to a server / dedicated pc, within the same physical location. Each of our 'units' has this hardware setup. For a quick resolution we deploy our application to the dedicated pc, and have the panel pc remote desktop to an account which then activates the application. This works but seems a little clunky / rough approach. We did this because the panel pc is rather limited. Now that we have more time, I was wondering if I should separate the application into a gui / application. Deploy the gui logic on the panel pc, and the business/database logic on the dedicated pc. The app is in Java so I was wondering what technology would be best? I was thinking of using RMI, but its not really a client/server app, as there is only one client. Should I stick with RMI, or use Sockets or something else? It will be easy to implement as the application is old, and manually wraps and unwraps data which passes through one class / method call to remote services. All I would have to do is 'RMI' this one method call, and the app will do its own stuff. Cheers.

  • Django's post_save signal behaves weirdly with models using multi-table inheritance

    - by hekevintran
    Django's post_save signal behaves weirdly with models using multi-table inheritance I am noticing an odd behavior in the way Django's post_save signal works when using a model that has multi-table inheritance. I have these two models: class Animal(models.Model): category = models.CharField(max_length=20) class Dog(Animal): color = models.CharField(max_length=10) I have a post save callback called echo_category: def echo_category(sender, **kwargs): print "category: '%s'" % kwargs['instance'].category post_save.connect(echo_category, sender=Dog) I have this fixture: [ { "pk": 1, "model": "animal.animal", "fields": { "category": "omnivore" } }, { "pk": 1, "model": "animal.dog", "fields": { "color": "brown" } } ] In every part of the program except for in the post_save callback the following is true: from animal.models import Dog Dog.objects.get(pk=1).category == u'omnivore' # True When I run syncdb and the fixture is installed, the echo_category function is run. The output from syncdb is: $ python manage.py syncdb --noinput Installing json fixture 'initial_data' from '~/my_proj/animal/fixtures'. category: '' Installed 2 object(s) from 1 fixture(s) The weird thing here is that the dog object's category attribute is an empty string. Why is it not 'omnivore' like it is everywhere else? As a temporary (hopefully) workaround I reload the object from the database in the post_save callback: def echo_category(sender, **kwargs): instance = kwargs['instance'] instance = sender.objects.get(pk=instance.pk) print "category: '%s'" % instance.category post_save.connect(echo_category, sender=Dog) This works but it is not something I like because I must remember to do it when the model inherits from another model and it must hit the database again. The other weird thing is that I must do instance.pk to get the primary key. The normal 'id' attribute does not work (I cannot use instance.id). I do not know why this is. Maybe this is related to the reason why the category attribute is not doing the right thing?

  • CharField values disappearing after save (readonly field)

    - by jamida
    I'm implementing simple "grade book" application where the teacher would be able to update the grades w/o being allowed to change the students' names (at least not on the update grade page). To do this I'm using one of the read-only tricks, the simplest one. The problem is that after the SUBMIT the view is re-displayed with 'blank' values for the students. I'd like the students' names to re-appear. Below is the simplest example that exhibits this problem. (This is poor DB design, I know, I've extracted just the relevant parts of the code to showcase the problem. In the real example, student is in its own table but the problem still exists there.) models.py class Grade1(models.Model): student = models.CharField(max_length=50, unique=True) finalGrade = models.CharField(max_length=3) class Grade1OForm(ModelForm): student = forms.CharField(max_length=50, required=False) def __init__(self, *args, **kwargs): super(Grade1OForm,self).__init__(*args, **kwargs) instance = getattr(self, 'instance', None) if instance and instance.id: self.fields['student'].widget.attrs['readonly'] = True self.fields['student'].widget.attrs['disabled'] = 'disabled' def clean_student(self): instance = getattr(self,'instance',None) if instance: return instance.student else: return self.cleaned_data.get('student',None) class Meta: model=Grade1 views.py from django.forms.models import modelformset_factory def modifyAllGrades1(request): gradeFormSetFactory = modelformset_factory(Grade1, form=Grade1OForm, extra=0) studentQueryset = Grade1.objects.all() if request.method=='POST': myGradeFormSet = gradeFormSetFactory(request.POST, queryset=studentQueryset) if myGradeFormSet.is_valid(): myGradeFormSet.save() info = "successfully modified" else: myGradeFormSet = gradeFormSetFactory(queryset=studentQueryset) return render_to_response('grades/modifyAllGrades.html',locals()) template <p>{{ info }}</p> <form method="POST" action=""> <table> {{ myGradeFormSet.management_form }} {% for myform in myGradeFormSet.forms %} {# myform.as_table #} <tr> {% for field in myform %} <td> {{ field }} {{ field.errors }} </td> {% endfor %} </tr> {% endfor %} </table> <input type="submit" value="Submit"> </form>

  • Linux Mounting Problem

    - by Sam
    I have an Iomega Network Attached Storage device on my Windows network. I am trying to use a clonezilla live USB flash drive to backup my netbook to my Iomega Network Attached Storage device. The clonezilla USB flash drive runs linux. I'm having trouble getting the Network Attached Storage unit to mount using the following command: mount -t cifs -o username="myUsername" //192.168.1.100/backup /home/partimg The response from linux is: [134.730738] CIFS VFS: cifs_mount failed w/return code = -6 retrying with upper case share name [134.788461] CIFS VFS: cifs_mount failed w/return code = -6 mount error(6): No such device or address Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) I also tried adding the following to my username: username="myUsername,domain=workgroup" but that did not change the error. I am able to ping the network attached storage unit from linux on my netbook. I also booted from a Slax Live USB Flash Drive and Slax auto-mounted my network attached storage unit via Samba. Unfortunately, I don't believe that I can run clonezilla from inside the Slax installation. Does anyone have any insight about what is wrong with my mount statement? Or is there something peculiar about Iomega drives which makes this impossible?

  • Geographically distributed file system with preferred locality

    - by dpb
    Hi All -- I'm building a application that needs to distribute a standard file server across a few sites over a WAN. Basically, each site needs to write a lot of misc files of varying size (some in the 100s MB range, but most small), and the application is written such that collisions aren't a problem. I'd like to have a system set up that meets the following qualifications: Each site can store files in a shared "namespace". That is, all the files would show up in the same filesystem. Each site would not send data over the WAN unless necessary. I.e., there would be local storage on each side of the WAN that would be "merged" into the same logical filesystem. Linux & Free ($$$) is a must. Basically, something like a central NFS share would meet most of the requirements, however it would not allow the locally written data to stay local. All data from remote sides of the WAN would be copied locally all the time. I have looked into Lustre, and have run some successful tests with it, however, it appears to distribute files fairly uniformly across the distributed storage. I have dug through the documentation and have not found anything that automatically will "prefer" local storage over remote storage. Even something that went with the lowest latency storage would be fine. It would work most of the time, which would meet this application's requirements. Any ideas?

  • How can I use a Shader in XNA to color single pixels?

    - by George Johnston
    I have a standard 800x600 window in my XNA project. My goal is to color each individual pixel based on a rectangle array which holds boolean values. Currently I am using a 1x1 Texture and drawing each sprite in my array. I am very new to XNA and come from a GDI background, so I am doing what I would have done in GDI, but it doesn't scale very well. I have been told in another question to use a Shader, but after much research, I still haven't been able to find out how to accomplish this goal. My application loops through the X and Y coordinates of my rectangular array, does calculations based on each value, and reassigns/moves the array around. At the end, I need to update my "Canvas" with the new values. A smaller sample of my array would look like: 0,0,0,0,0,0,0 0,0,0,0,0,0,0 0,0,0,0,0,0,0 1,1,1,1,1,1,1 1,1,1,1,1,1,1 How can I use a shader to color each pixel?

  • XDebug, how to disable remote debugging for single .php file?

    - by Kirzilla
    Hello, I'm using Eclipse IDE + remote Xdebug. EclipseIDE is listening 9000 port for some kind of Xdebug information. There are some php scripts running by cron on server. So, every cron execution xdebug is sending information to my workstation and EclipseIDE is trying to find this file in my project. But file couldn't be find because cron running scrits do not relate to the project I'm working with. So, every cron run Eclipse IDE is alerting this message http://img2.pict.com/22/fc/86/3299517/0/screenshot2b142.png I've tried to add to cron executed php scripts some strings... if (function_exists('xdebug_disable')) { xdebug_disable(); } ... but it didn't helped. Any ideas? Thank you

  • An autoformat tool to automatically insert braces around single-line clauses?

    - by Brian Deacon
    So assuming that in our work environment we've decided that the One True Faith forbids this: if (something) doSomething(); And instead we want: if (something) { doSomething(); } Is there a tool that will do that automagically? Awesomest would be to have eclipse just do it, but since we're really just recovering from one ex-employee that thought he was too pretty for coding conventions, a less-friendly tool that would do it right just once would suffice.

  • How can I fast-forward a single git commit, programmatically?

    - by Norman Ramsey
    I periodically get message from git that look like this: Your branch is behind the tracked remote branch 'local-master/master' by 3 commits, and can be fast-forwarded. I would like to be able to write commands in a shell script that can do the following: How can I tell if my current branch can be fast-forwarded from the remote branch it is tracking? How can I tell how many commits "behind" my branch is? How can I fast-forward by just one commit, so that for example, my local branch would go from "behind by 3 commits" to "behind by 2 commits"? (For those who are interested, I am trying to put together a quality git/darcs mirror.)

  • Windows XP Does Not Follow CNAME Shares

    - by user49349
    I am supporting a mix of Windows XP Pro and Windows 7 desktops in my Active Directory network, and I am having an odd issue with XP and CNAME records. Say I have a record in my DNS for a server with an A name of something like STORAGE.company.local and give it a CNAME of NAS.company.local. I can go onto an XP and 7 computer, and ping NAS and it will automatically resolve to STORAGE.company.local. If I am on Windows 7 and go to run and enter \\STORAGE or \\NAS, it will go to that server in Explorer. If I do the same in XP, STORAGE will work but NAS will not. It just times out Is there some setting buried in XP to make this work properly?

  • Why do SNMP agents need MIB files?

    - by user1495181
    After reading up on SNMP and some of the questions help here I think understand the agent role as a SNMP service to device (Like SQL, it is an API to storage). When you execute a SQL query the SQL engine does all the work and returns the result - You don't need to be aware of how the storage and where the storage is done. But MIBs are not actual storage , so what is the role of my agent? if the agent only register the MIB like i follow in this tutorial, is it not used as handler at all? Say that I want monitor my application's pending request queue, so I want an agent that all SNMP request for application_pending_request will be fired for it and it will return the queue depth. Why do I need to have an actual MIB when all I need to poll my application queue in order to get result?

  • Is it approproate it use django signals withing the same app

    - by Alex Lebedev
    Trying to add email notification to my app in the cleanest way possible. When certain fields of a model change, app should send a notification to a user. Here's my old solution: from django.contrib.auth import User class MyModel(models.Model): user = models.ForeignKey(User) field_a = models.CharField() field_b = models.CharField() def save(self, *args, **kwargs): old = self.__class__.objects.get(pk=self.pk) if self.pk else None super(MyModel, self).save(*args, **kwargs) if old and old.field_b != self.field_b: self.notify("b-changed") # Sevelar more events here # ... def notify(self, event) subj, text = self._prepare_notification(event) send_mail(subj, body, settings.DEFAULT_FROM_EMAIL, [self.user.email], fail_silently=True) This worked fine while I had one or two notification types, but after that just felt wrong to have so much code in my save() method. So, I changed code to signal-based: from django.db.models import signals def remember_old(sender, instance, **kwargs): """pre_save hanlder to save clean copy of original record into `old` attribute """ instance.old = None if instance.pk: try: instance.old = sender.objects.get(pk=instance.pk) except ObjectDoesNotExist: pass def on_mymodel_save(sender, instance, created, **kwargs): old = instance.old if old and old.field_b != instance.field_b: self.notify("b-changed") # Sevelar more events here # ... signals.pre_save.connect(remember_old, sender=MyModel, dispatch_uid="mymodel-remember-old") signals.post_save.connect(on_mymodel_save, sender=MyModel, dispatch_uid="mymodel-on-save") The benefit is that I can separate event handlers into different module, reducing size of models.py and I can enable/disable them individually. The downside is that this solution is more code and signal handlers are separated from model itself and unknowing reader can miss them altogether. So, colleagues, do you think it's worth it?

  • How can I execute several maven plugins within a single phase and set their respective execution ord

    - by Yaneeve
    Hi all, I would like to breakup certain phases in the maven life cycle into sub phases. I would like to control the execution flow from one sub-phase to another, sort of like with ant dependencies. For example, I would like to use the NSIS plugin in order to package up my project into an installer at the package stage, AFTER my project had been packaged into a war file. I would like to do all that at the package phase. Is that possible? Thanks

  • Why can't I pipe the output of uuencode to mailx in a single Perl open statement?

    - by CheeseConQueso
    Here's my code that is not working: print "To: "; my $to=<>; chomp $to; print "From: "; my $from=<>; chomp $from; print "Attach: "; my $attach=<>; chomp $attach; print "Subject: "; my $subject=<>; chomp $subject; print "Message: "; my $message=<>; chomp $message; my $mail_fh = \*MAIL; open $mail_fh, "uuencode $attach $attach |mailx -m -s \"$subject\" -r $from $to"; print $mail_fh $message; close($mail_fh); The mailx command works fine off the command line, but not in this Perl script context. Any idea what I'm missing? I suspect that this line's format/syntax: open $mail_fh, "uuencode $attach $attach |mailx -m -s \"$subject\" -r $from $to"; is the culprit.

  • How to optimize Dijkstra algorithm for a single shortest path between 2 nodes?

    - by Nazgulled
    Hi, I was trying to understand this implementation in C of the Dijkstra algorithm and at the same time modify it so that only the shortest path between 2 specific nodes (source and destination) is found. However, I don't know exactly what do to. The way I see it, there's nothing much to do, I can't seem to change d[] or prev[] cause those arrays aggregate some important data for the shortest path calculation. The only thing I can think of is stopping the algorithm when the path is found, that is, break the cycle when mini = destination when it's being marked as visited. Is there anything else I could do to make it better or is that enough? P.S: I just noticed that the for loops start at 1 until <=, why can't it start at 0 and go until <?
