  • Confusion on C++ Python extensions. Things like getting C++ values for python values.

    - by Matthew Mitchell
    I'm wanted to convert some of my python code to C++ for speed but it's not as easy as simply making a C++ function and making a few function calls. I have no idea how to get a C++ integer from a python integer object. I have an integer which is an attribute of an object that I want to use. I also have integers which are inside a list in the object which I need to use. I wanted to test making a C++ extension with this function: def setup_framebuffer(surface,flip=False): #Create texture if not done already if surface.texture is None: create_texture(surface) #Render child to parent if surface.frame_buffer is None: surface.frame_buffer = glGenFramebuffersEXT(1) glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, c_uint(int(surface.frame_buffer))) glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_COLOR_ATTACHMENT0_EXT, GL_TEXTURE_2D, surface.texture, 0) glPushAttrib(GL_VIEWPORT_BIT) glViewport(0,0,surface._scale[0],surface._scale[1]) glMatrixMode(GL_PROJECTION) glLoadIdentity() #Load the projection matrix if flip: gluOrtho2D(0,surface._scale[0],surface._scale[1],0) else: gluOrtho2D(0,surface._scale[0],0,surface._scale[1]) That function calls create_texture, so I will have to pass that function to the C++ function which I will do with the third argument. This is what I have so far, while trying to follow information on the python documentation: #include <Python.h> #include <GL/gl.h> static PyMethodDef SpamMethods[] = { ... {"setup_framebuffer", setup_framebuffer, METH_VARARGS,"Loads a texture from a Surface object to the OpenGL framebuffer."}, ... {NULL, NULL, 0, NULL} /* Sentinel */ }; static PyObject * setup_framebuffer(PyObject *self, PyObject *args){ bool flip; PyObject *create_texture, *arg_list,*pyflip,*frame_buffer_id; if (!PyArg_ParseTuple(args, "OOO", &surface,&pyflip,&create_texture)){ return NULL; } if (PyObject_IsTrue(pyflip) == 1){ flip = true; }else{ flip = false; } Py_XINCREF(create_texture); //Create texture if not done already if(texture == NULL){ arglist = Py_BuildValue("(O)", surface) result = PyEval_CallObject(create_texture, arglist); Py_DECREF(arglist); if (result == NULL){ return NULL; } Py_DECREF(result); } Py_XDECREF(create_texture); //Render child to parent frame_buffer_id = PyObject_GetAttr(surface, Py_BuildValue("s","frame_buffer")) if(surface.frame_buffer == NULL){ glGenFramebuffersEXT(1,frame_buffer_id); } glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, surface.frame_buffer)); glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_COLOR_ATTACHMENT0_EXT, GL_TEXTURE_2D, surface.texture, 0); glPushAttrib(GL_VIEWPORT_BIT); glViewport(0,0,surface._scale[0],surface._scale[1]); glMatrixMode(GL_PROJECTION); glLoadIdentity(); //Load the projection matrix if (flip){ gluOrtho2D(0,surface._scale[0],surface._scale[1],0); }else{ gluOrtho2D(0,surface._scale[0],0,surface._scale[1]); } Py_INCREF(Py_None); return Py_None; } PyMODINIT_FUNC initcscalelib(void){ PyObject *module; module = Py_InitModule("cscalelib", Methods); if (m == NULL){ return; } } int main(int argc, char *argv[]){ /* Pass argv[0] to the Python interpreter */ Py_SetProgramName(argv[0]); /* Initialize the Python interpreter. Required. */ Py_Initialize(); /* Add a static module */ initscalelib(); }

  • Sitecore E-Commerce Module - Discount/Promotional Codes

    - by Zachary Kniebel
    I am working on a project for which I must use Sitecore's E-Commerce Module (and Sitecore 6.5 rev. 120706 - aka 'Update 5') to create a web-store. One of the features that I am trying to implement is a generic promotional/discount code system - customer enters a code at checkout which grants a discount like 'free shipping', '20% off', etc. At the moment, I am looking for some guidance (a high-level solution, a few pseudo-ideas, some references to review, etc) as to how this can be accomplished. Summary: What I am looking for is a way to detect whether or not the user entered a promo code at a previous stage in the checkout line, and to determine what that promo code is, if they did. Progress Thus Far: I have thoroughly reviewed all of the Sitecore E-Commerce Services (SES) documentation, especially "SES Order Line Extension" documentation (which I believe will have to be modified/extended in order to accomplish this task). Additionally, I have thoroughly reviewed the Sitecore Community article Extending Sitecore E-Commerce - Pricing and believe that it may be a useful guide for applying a discount statically, but does not say much in the way of applying a discount dynamically. After reviewing these documents, I have come up with the following possible high-level solution to start from: I create a template to represent a promotional code, which holds all data relevant to the promotion (percent off, free shipping, code, etc). I then create another template (based on the Product Search Group template) that holds a link to an item within a global "Promotional Code" items folder. Next, I use the Product Search Group features of my new template to choose which products to apply the discount to. In the source code for the checkout I create a class that checks if a code has been entered and, if so, somehow carry it through the rest of the checkout process. This is where I get stuck. More Details: No using cookies No GET requests No changing/creating/deleting items in the Sitecore Database during the checkout process (e.g., no manipulation of fields of a discount item during checkout to signal that the discount has been applied) must stay within the scope of C# Last Notes: I will update this post with any more information that I find/progress that I make. I upgrade all answers that are relevant and detailed, thought-provoking, or otherwise useful to me and potentially useful to others, in addition to any high-level answers that serve as a feasible solution to this problem; even if your idea doesn't help me, if I think it will help someone else I will still upgrade it. Thanks, in advance, for all your help! :)

  • Is it possible to build multi module structure with Maven for PHP?

    - by Softy
    I have to build an application using Maven for PHP that has multiple modules. The scenario in which the maven seems to not work is this: I have a common module and a client module depending on the first one. When doing "mvn site" on the client module which depends on the common module, the test fails to see the paths to the common module. Is there a flow in my build or this is just not possible?

  • How do I best handle a needed patch for Perl/Tk?

    I am making a change to Perl/Tk for an application that has its own resident Perl and modules installation (so we can drop the app in and go).

  • Hadoop streaming with Python and python subprocess

    - by Ganesh
    I have established a basic hadoop master slave cluster setup and able to run mapreduce programs (including python) on the cluster. Now I am trying to run a python code which accesses a C binary and so I am using the subprocess module. I am able to use the hadoop streaming for a normal python code but when I include the subprocess module to access a binary, the job is getting failed.

  • Creating a draft version of the page before publishing in Drupal 6?

    - by Marco
    I've been looking for a good way to handle revisions in Drupal, but I am yet to succeed. For some reason there is no built in way to save a draft (that I've found so far), and the modules I've tried so far do not seem to fully work. First I tried save_as_draft, which seemed to do almost what I wanted, and if I'm not mistaken, also handles CCK fields. Sadly it seems to be broken somehow, so I can't edit a page once I've saved it as a draft.. maybe I could fix it by going through the code, but that would not be my preferred solution. The other module I tried is aptly named draft, but from what I can tell, this module only handles the title and body fields, and does this in a way that appear odd to me. Is there some common practice to solve this? I couldn't imagine that nobody had to solve this before, but I haven't found any good solution to it yet. Clarification I need this functionality for already existing content, that is, I want to be able to create and edit a draft version of an already published page, while the "old" version would still be available to anonymous users.

  • Ruby Doesn't Recognize Alias Method

    - by Jesse J
    I'm trying to debug someone else's code and having trouble figuring out what's wrong. When I run rake, one of the errors I get is: 2) Error: test_math(TestRubyUnits): NoMethodError: undefined method `unit_sin' for CMath:Module /home/user/ruby-units/lib/ruby_units/math.rb:21:in `sin' This is the function that calls the method: assert_equal Math.sin(pi), Math.sin("180 deg".unit) And this is what the class looks like: module Math alias unit_sin sin def sin(n) Unit === n ? unit_sin(n.to('radian').scalar) : unit_sin(n) end alias unit_cos cos def cos(n) Unit === n ? unit_cos(n.to('radian').scalar) : unit_cos(n) end ... module_function :unit_sin module_function :sin module_function :unit_cos module_function :cos ... end (The ellipsis means "more of the same"). As far as I can see, this is valid Ruby code. Is there something I'm missing here that's causing the error, or could the error be coming from something else? Update: I'm wondering if the problem has to do with namespaces. This code is attempting to extend CMath, so perhaps the alias and/or module_function isn't actually getting into CMath, or something like that....

  • Saving information in the IO System

    - by djTeller
    Hi Kernel Gurus, I need to write a kernel module that simulate a "multicaster" Using the /proc file system. Basically it need to support the following scenarios: 1) allow one write access to the /proc file and many read accesses to the /proc file. 2) The module should have a buffer of the contents last successful write. Each write should be matched by a read from all reader. Consider scenario 2, a writer wrote something and there are two readers (A and B), A read the content of the buffer, and then A tried to read again, in this case it should go into a wait_queue and wait for the next message, it should not get the same buffer again. I need to keep a map of all the pid's that already read the current buffer, and in case they try to read again and the buffer was not changed, they should be blocked until there is a new buffer. I'm trying to figure it there is a way i can save that info without a map. I heard there are some redundant fields inside the I/O system the I can use to flag a process if it already read the current buffer. Can someone give me a tip where should i look for that field ? how can i save info on the current process without keeping a "map" of pid's and buffers ? Thanks!

  • Building modules with linux kernel for custom flavor

    - by Chandan Apsangi
    I followed the instructions given in the link: http://blog.avirtualhome.com/how-to-compile-a-new-ubuntu-11-04-natty-kernel/ for building a custom kernel and booting it. Everything works fine, except that when building it, I used the option skipmodule=true (as given in this link), so I guess the modules are not built for this kernel. I'm saying this because after I installed the image (using dpkg -i), when I run 'ls -l' in the /lib/modules/2.6.38-11-i5 folder, all the files/folders except the 'kernel' folder have got updated (Btw, I had built it last time and it had worked fine,this is an update on the same kernel source). So is there some option/command that I missed that exports the modules as well? Thanks for your help.

  • Symfony sfDoctrineGuard plugin sfGuardUser module

    - by Joe Mc
    When using sfDoctrineGuard plugin, it automatically generates the backend administration functionality where I can edit users of the system and assign them permissions. So I visit http://.../backend_dev.php/sf_guard_user/:id/edit where I am presented with the user's information including the available permissions to select. By default the permissions are shown as a multiple select box, HTML follows: <select name="sf_guard_user[permissions_list][]" multiple="multiple" id="sf_guard_user_permissions_list"> <option value="1">Permission1</option> <option value="2">Permission2</option> <option value="3">Permission3</option> <option value="4">Permission4</option> </select> What I would prefer is a list of checkboxes. So I searched around and found that if I add the option "expanded" set to true to the following code: 'permissions_list' => new sfWidgetFormDoctrineChoice(array('multiple' => true, 'model' => 'sfGuardPermission', 'expanded' => true,)), The code is part of this file: lib/form/doctrine/sfDoctrineGuardPlugin/base/BasesfGuardUserForm.class.php. I don't think I should've edited this file (potential for changes to be overwritten should sfDoctrineGuard ever be re-installed) but couldn't think of another way to make it work. The generated HTML is as follows: <ul class="checkbox_list"> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="1" id="sf_guard_user_permissions_list_1" />&nbsp;<label for="sf_guard_user_permissions_list_1">Permission1</label></li> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="2" id="sf_guard_user_permissions_list_2" />&nbsp;<label for="sf_guard_user_permissions_list_2">Permission2</label></li> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="3" id="sf_guard_user_permissions_list_3" />&nbsp;<label for="sf_guard_user_permissions_list_3">Permission3</label></li> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="4" id="sf_guard_user_permissions_list_4" />&nbsp;<label for="sf_guard_user_permissions_list_4">Permission4</label></li> </ul> What I need to do now is split up the permissions based on their prefix. For example if I had permissions named user_action1, user_action2, file_action1, file_action2, they would display like: User checkbox (custom label) Action One checkbox Action Two File checkbox (custom label) Action One checkbox Action Two but have no idea where to start with this. It would be easy if there was a template to edit but since I'm dealing with the Forms framework it is my understanding that the templates are generated on the fly - I can see them in my symonfy cache folder. How would I go about this? I started writing my own sfWidgetFormDoctrineChoicePermission class that extends the same class as sfWidgetFormDoctrineChoice but am struggling to edit the rendering functions correctly for the desired output. Is this the correct way to go about this work? I also need to integrate my sfGuardUserProfile model into the edit user page (same as above), I read somwhere that editing the generator.yml file for the sfGuardUser plugin module and simply adding the field names from the sfGuardUserProfile table would make it work, but sadly it doesn't. Any help with any of my queries would be appreciated. Thanks

  • Perl IO modules possibly causing issues in Net::DNS module

    - by Rich
    Hi! I’m porting some software that I wrote for a White Russian OpenWRT system to a new Kamikaze 8.09.1 OpenWRT system but I am having some serious issues that I’m hoping you can help me with. Old system Linux kernel 2.4.34 MIPSEL arch Perl 5.8.7 Net::DNS 0.48 IO 1.21 IO::Socket 1.28 IO::Socket::INET 1.28 New system Linux kernel 2.6.26.8 MIPS arch Perl 5.10.0 Net::DNS 0.66 IO 1.23_01 IO::Socket 1.30_01 IO::Socket::INET 1.31 First, let me provide some background information… I am trying to resolve my server (clearprobe.winbeam.com) from within my Perl program and see the following if I enable debugging in Net::DNS: resolve: Server 'clearprobe-ddns.winbeam.com' ;; query(clearprobe-ddns.winbeam.com) ;; setting up an AF_INET() family type UDP socket ;; send_udp(192.168.88.1:53) ;; send_udp(4.2.2.2:53) ;; send_udp(192.168.88.1:53) ;; send_udp(4.2.2.2:53) resolve: res->errorstring: query timed out Both of these servers resolve clearprobe.winbeam.com fine from the command line: root@cwb-2-11:~# echo “nameserver 192.168.88.1” > /etc/resolv.conf root@cwb-2-11:~# nslookup clearprobe-ddns.winbeam.com Server: 192.168.88.1 Address 1: 192.168.88.1 router Name: clearprobe-ddns.winbeam.com Address 1: 64.13.48.40 64-13-48-40.war.clearwire-dns.net root@cwb-2-11:~# echo “nameserver 4.2.2.2” > /etc/resolv.conf root@cwb-2-11:~# nslookup clearprobe-ddns.winbeam.com Server: 4.2.2.2 Address 1: 4.2.2.2 vnsc-bak.sys.gtei.net Name: clearprobe-ddns.winbeam.com Address 1: 64.13.48.40 64-13-48-40.war.clearwire-dns.net Using Perl’s call to the C gethostbyaddr() function works fine, but I need to do another lookup later in the software which requires that I specify the nameserver (clearprobe-ddns.winbeam.com is the authority for my internal DNS zone), hence my Net::DNS requirement. Now, here is the IO module-specific information: What I am seeing is that the reply is coming back from the nameserver (confirmed via tcpdump – I can send the captures if you’d like), but the UDP packets are sitting in the process’s UDP receive queue pending reception by Net::DNS (the approx 1752 bytes per response stay queued waiting for $sel-can_read()): root@cwb-2-11:~# netstat -una Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State udp 1752 0 0.0.0.0:52680 0.0.0.0:* root@cwb-2-11:~# netstat -una Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State udp 5256 0 0.0.0.0:52680 0.0.0.0:* If I force $sock[AF_INET]-recv($buf, $self-_packetsz) around line 803 of /usr/lib/perl5/5.10/Net/DNS/Resolver/Base.pm, instead of waiting for IO::Select’s can_read() function ( @ready = $sel-can_read($timeout)) to populate @ready, the response is received and processed. Any idea what could be causing this issue? In a possibly related matter, I noticed in another script that the following code fails in the same manner (network responses stay in the process’s TCP receive queue) with the new system: $sock = new IO::Socket::INET( PeerAddr => "$server", PeerPort => 37, Proto => 'tcp', Timeout => 5 ); Whereas the following code works: $sock = new IO::Socket::INET( PeerAddr => "$server", PeerPort => 37, Proto => 'tcp' ); I have looked through the NET::DNS code and don’t see a timeout passed for the UDP sockets, so I am not sure if that this is related or not. Please let me know if I can provide you with any further information in order to help diagnose this issue. Thanks! -Rich

  • What are the basic features of an email module in a common web application?

    - by Coral Doe
    When developing an email module, what are the features to have in mind, besides actual email sending? I am talking about an email module that notifies users of events and periodically sends reports. The only other feature I have in mind is maintaining grey/black lists for users that do illegal operations in the system or any other things that may lead to email/domain/IP banning. Is there an etiquette for developing email modules? Are there some references of requirements for such modules?

  • Suspend fails and I know the module causing it. What can I do?

    - by ch0wn
    My suspend did not correctly since I installed a USB 3 extension card in my PC. Instead of going to S3, the computer just woke up instantly. dmesg gave the hint "usb_dev_suspend+0x0/0x20 returns -2" so I rmmod'ed the "xhci_hcd" module which did the trick. Is there a good way for me to work around this? The builds from the Kernel Mainline PPA did not help, unfortunately, and blacklisting the module is not my favorite option. Where is the best place for me to report this issue?

  • codepad.org Perl runner limitations

    - by Lemurik
    Sometimes I see people use http://codepad.org as a way to quickly run/test their Perl snippets (it supports doing that with a wide variety of languages, from C to Scheme to Perl). It's pretty obious that there must be some limitations as to what code/features can be tested with codepad - does anyone know what those limitations are for Perl runner? I'll get the ball rolling on my own observation: not every CPAN module is avialable :(

  • Please Explain Drupal schema and drupal_write_record

    - by Aaron
    Hi. A few questions. 1) Where is the best place to populate a new database table when a module is first installed, enabled? I need to go and get some data from an external source and want to do it transparently when the user installs/enables my custom module. I create the schema in {mymodule}_schema(), do drupal_install_schema({tablename}); in hook_install. Then I try to populate the table in hook_enable using drupal_write_record. I confirmed the table was created, I get no errors when hook_enable executes, but when I query the new table, I get no rows back--it's empty. Here's one variation of the code I've tried: /** * Implementation of hook_schema() */ function ncbi_subsites_schema() { // we know it's MYSQL, so no need to check $schema['ncbi_subsites_sites'] = array( 'description' => 'The base table for subsites', 'fields' => array( 'site_id' => array( 'description' => 'Primary id for site', 'type' => 'serial', 'unsigned' => TRUE, 'not null' => TRUE, ), // end site_id 'title' => array( 'description' => 'The title of the subsite', 'type' => 'varchar', 'length' => 255, 'not null' => TRUE, 'default' => '', ), //end title field 'url' => array( 'description' => 'The URL of the subsite in Production', 'type' => 'varchar', 'length' => 255, 'default' => '', ), //end url field ), //end fields 'unique keys' => array( 'site_id'=> array('site_id'), 'title' => array('title'), ), //end unique keys 'primary_key' => array('site_id'), ); // end schema return $schema; } Here's hook_install: function ncbi_subsites_install() { drupal_install_schema('ncbi_subsites'); } Here's hook_enable: function ncbi_subsites_enable() { drupal_get_schema('ncbi_subsites_site'); // my helper function to get data for table (not shown) $subsites = ncbi_subsites_get_subsites(); foreach( $subsites as $name=>$attrs ) { $record = new stdClass(); $record->title = $name; $record->url = $attrs['homepage']; drupal_write_record( 'ncbi_subsites_sites', $record ); } } Can someone tell me what I'm missing?

  • Linux Kernel - traverse to buffer heads

    - by CodeRanger
    In the Linux kernel, is there a way to traverse down to the buffer_heads from within a module? I can see how to get to struct bio (task_struct macro: current-bio). But how can I get to the buffer heads? The buffer_head struct holds some information I'd like to obtain at any point regarding physical block numbers.

  • pager problem with drupal and taxonomy

    - by andersandersson666
    Ok, so this is probably a silly question, but i thought i'd put it out there anyway: I know it's a strange solution to a simple problem, but i needed to control the listing of the nodes in the taxonomy pages, which i didn't feel i got the traditional way. So i went ahead and created a module that fetches the nodes based on taxonomy (taxonomy_select_nodes()), and i wanted a pager to go along with that. Here's the code: function theModule_recipeList(){ $path = drupal_get_path_alias($_GET['q']); $args = explode("/",$path); $themePath = drupal_get_path("theme", "theTheme"); $term = taxonomy_get_term_by_name($args[1]); $tid = $term[0]->tid; $nodes = taxonomy_select_nodes(array($tid)); $output = "<div id='recipeListWrapper'>"; while($row = db_fetch_object($nodes)){ $node = node_load($row->nid); if($node->uid != 1){ $userClass="user"; } else{ $userClass="admin"; } $output .= " <div class='receptThumbnailWrapper'> <div class='wrapper'> <img src='".base_path().$themePath."/graphics/recept-default-small.png' /> <h3><a href='".base_path() . $node->path."'>".$node->title."</a></h3> <div class='recipeType $userClass'></div> </div> </div> "; } $output .= "</div>"; return $output; } Now, the module works as i planned and all (even though it is a duct tape sort of solution, i know), and the pager prints and works. The problem is that the pager prints before anything else. I suspect that it is because i call taxonomy_select_nodes before $output is returned, but i need it to get the nodes i want. Please, any suggestions is greatly appreciated. /Anders

  • fake python modules via symlinks: on windows?

    - by eudoxos
    I have several compiled python modules; they are put into a single .so (to avoid runtime linking, there are cross-module symbol dependencies), but a number of symlinks points to this .so: libfoo.so -> liball.so libbar.so -> liball.so liball.so This way, I can do import foo (Python will call initfoo() defined in liball.so) or import bar (calls initbar()). I am wondering if this approach will work on Windows?
