  • Confused as to use a class or a function: Writing XML files using lxml and Python

    - by PulpFiction
    Hi. I need to write XML files using lxml and Python. However, I can't figure out whether to use a class to do this or a function. The point being, this is the first time I am developing a proper software and deciding where and why to use a class still seems mysterious. I will illustrate my point. For example, consider the following function based code I wrote for adding a subelement to a etree root. from lxml import etree root = etree.Element('document') def createSubElement(text, tagText = ""): etree.SubElement(root, text) # How do I do this: element.text = tagText createSubElement('firstChild') createSubElement('SecondChild') As expected, the output of this is: <document> <firstChild/> <SecondChild/> </document> However as you can notice the comment, I have no idea how to do set the text variable using this approach. Is using a class the only way to solve this? And if yes, can you give me some pointers on how to achieve this?

  • Knowledge for writing a compiler for Win32

    - by saf
    I have created an interpreter for my programming language (educational) and now I'd like to go one step further and create a compiler for it. I know that this is pretty hard work. What I already know is: I need to translate my input language to assembler A lot, isn't it? Now what I don't know is: What assembler do I need to create Win32 PE executables like, for example, Visual Studio does? What about file headers? I'd prefer not to use MASM but it seems like I'll have to. How to combine the assembler with my compiler?

  • Multiprogramming in Django, writing to the Database

    - by Marcus Whybrow
    Introduction I have the following code which checks to see if a similar model exists in the database, and if it does not it creates the new model: class BookProfile(): # ... def save(self, *args, **kwargs): uniqueConstraint = {'book_instance': self.book_instance, 'collection': self.collection} # Test for other objects with identical values profiles = BookProfile.objects.filter(Q(**uniqueConstraint) & ~Q(pk=self.pk)) # If none are found create the object, else fail. if len(profiles) == 0: super(BookProfile, self).save(*args, **kwargs) else: raise ValidationError('A Book Profile for that book instance in that collection already exists') I first build my constraints, then search for a model with those values which I am enforcing must be unique Q(**uniqueConstraint). In addition I ensure that if the save method is updating and not inserting, that we do not find this object when looking for other similar objects ~Q(pk=self.pk). I should mention that I ham implementing soft delete (with a modified objects manager which only shows non-deleted objects) which is why I must check for myself rather then relying on unique_together errors. Problem Right thats the introduction out of the way. My problem is that when multiple identical objects are saved in quick (or as near as simultaneous) succession, sometimes both get added even though the first being added should prevent the second. I have tested the code in the shell and it succeeds every time I run it. Thus my assumption is if say we have two objects being added Object A and Object B. Object A runs its check upon save() being called. Then the process saving Object B gets some time on the processor. Object B runs that same test, but Object A has not yet been added so Object B is added to the database. Then Object A regains control of the processor, and has allready run its test, even though identical Object B is in the database, it adds it regardless. My Thoughts The reason I fear multiprogramming could be involved is that each Object A and Object is being added through an API save view, so a request to the view is made for each save, thus not a single request with multiple sequential saves on objects. It might be the case that Apache is creating a process for each request, and thus causing the problems I think I am seeing. As you would expect, the problem only occurs sometimes, which is characteristic of multiprogramming or multiprocessing errors. If this is the case, is there a way to make the test and set parts of the save() method a critical section, so that a process switch cannot happen between the test and the set?

  • Synchronizing reading and writing with synchronous NamedPipes

    - by Mike Trader
    A Named Pipe Server is created with hPipe = CreateNamedPipe( zPipePath, PIPE_ACCESS_DUPLEX, PIPE_TYPE_BYTE | PIPE_WAIT | PIPE_READMODE_BYTE, PIPE_UNLIMITED_INSTANCES, 8192, 8192, NMPWAIT_USE_DEFAULT_WAIT, NULL) Then we immediately call: ConnectNamedPipe( hPipe, BYVAL %NULL ) Which blocks until the client connects. Then we proceed directly to ReadFile( hPipe, ... The problem is that it takes the Client takes a finite amount of time to prepare and write all the fcgi request parameters. This has usually not completed before the Pipe Server performs its ReadFile(). The Read file operation thus finds no data in the pipe and the process fails. Is there a mechanism to tell when a Write() has occurred/finished after a client has connected to a NamedPipe? If I had control of the Client process, I could use a common Mutex, but I don't, and I really do not want to get into I/O completion ports just to solve this problem! I can of course use a simple timer to wait 60m/s or so which is usually plenty of time for the wrote to complete, but that is a horrible hack.

  • C - struct problems - writing

    - by Catarrunas
    Hello, I'm making a program in C, and I'mm having some troubles with memory, I think. So my problem is: I have 2 functions that return a struct. When I run only one function at a time I have no problem whatsoever. But when I run one after the other I always get an error when writting to the second struct. Function struct item* ReadFileBIN(char *name) -- reads a binary file. struct tables* getMesasInfo(char* Filename) -- reads a text file. My code is this: #include "stdafx.h" #include <stdio.h> #include <stdlib.h> #include <string.h> #include <time.h> int numberOfTables=0; int numberOfItems=0; //struct tables* mesas; //struct item* Menu; typedef struct item{ char nome[100]; int id; float preco; }; typedef struct tables{ int id; int capacity; bool inUse; }; struct tables* getMesasInfo(char* Filename){ struct tables* mesas; char *c; int counter,numberOflines=0,temp=0; char *filename=Filename; FILE * G; G = fopen(filename,"r"); if (G==NULL){ printf("Cannot open file.\n"); } else{ while (!feof(G)){ fscanf(G, "%s", &c); numberOflines++; } fclose(G); } /* Memory allocate for input array */ mesas = (struct tables *)malloc(numberOflines* sizeof(struct tables*)); counter=0; G=fopen(filename,"r"); while (!feof(G)){ mesas[counter].id=counter; fscanf(G, "%d", &mesas[counter].capacity); mesas[counter].inUse= false; counter++; } fclose(G); numberOfTables = counter; return mesas; } struct item* ReadFileBIN(char *name) { int total=0; int counter; FILE *ptr_myfile; struct item my_record; struct item* Menu; ptr_myfile=fopen(name,"r"); if (!ptr_myfile) { printf("Unable to open file!"); } while (!feof(ptr_myfile)){ fread(&my_record,sizeof(struct item),1,ptr_myfile); total=total+1; } numberOfItems=total-1; Menu = (struct item *)calloc(numberOfItems , sizeof(struct item)); fseek(ptr_myfile, sizeof(struct item), SEEK_END); rewind(ptr_myfile); for ( counter=1; counter < total ; counter++) { fread(&my_record,sizeof(struct item),1,ptr_myfile); Menu[counter] = my_record; printf("Nome: %s\n",Menu[counter].nome); printf("ID: %d\n",Menu[counter].id); printf("Preco: %f\n",Menu[counter].preco); } fclose(ptr_myfile); return Menu; } int _tmain(int argc, _TCHAR* argv[]) { struct item* tt = ReadFileBIN("menu.dat"); struct tables* t = getMesasInfo("Capacity.txt"); getchar(); }** Thanks in advance.

  • simple python file writing question

    - by aharon
    I'm learning Python, and have run into a bit of a problem. On my OSX install of Python 3.1, this happens in the console: >>> filename = "test" >>> reader = open(filename, 'r') >>> writer = open(filename, 'w') >>> reader.read() '' >>> writer.write("hello world\n") 12 >>> reader.read() '' And calling more test in BASH confirms that there is nothing in test. What's going on? Thanks.

Is it simply Upgrade the Database? I think I am being thrown off as there is no specific actor/customer and that the customer is the IT department.

    here's my web.config, running a WCF service in an application on IIS7, but nothing is being written to the specified file. permission on the file has been granted for everyone. </listeners> I can add a service reference just fine. I then try to call the service from a windows app and, after a few minutes, get an error on the machine running the windows app "Client is unable to finish the security negotiation within the configured timeout (00:00:00). The current negotiation leg is 1 (00:00:00)." but absolutely nothing is written to the trace log file specified in config. Is there something else I need to do to enable tracing? thanks for your help EDIT: "sources" section now matches the section recommended here: http://msdn.microsoft.com/en-us/library/aa702726.aspx I've added the "diagnostics and the event viewer shows: "Message Logging has been turned on.

  • jQuery .html not writing span on page load, rights the span on ajax response

    - by pedalpete
    I've got a bit of a calendar I'm building with events that go beyond the boundary of one day. I've got a graph which shows how many events are running concurrently. In order to graph out the events which go into another day, I look for hours24, and run an extra bit of code. jQuery('li#hour'+placeGroup+'_'+schedDay2+'_'+thisHour,nextDay).data('count', numStaff).html(''+printHour+''+numEvents+' scheduled').css('height',numEvents*5+'px'); The code is working, the li items are being found, proper height is the css is being applied, data is set, which I've checked by running alert(jQuery('li#hour'+placeGroup+'_'+schedDay2+'_'+thisHour,nextDay).data('count')); right after the pervious bit of code. The only thing that isn't being done is the .html(add span) stuff. I run this code in two places. Once when the page loads, and once when an action is taken which changes the number of events via an ajax response. The li DOM object I'm writting to is created before the script is run, and the height is being applied, but not the span, and only on page load. Any ideas on this one? I'm stumped.

  • Writing from an array to a file bash and new lines

    - by S1syphus
    I'm trying to write a script the generates a template file for Pashua (a perl script for creating GUI on osx) I want to crate an instance for each item in the array, so the ideal output would be: AB1.type = openbrowser AB1.label = Choose a master playlist file AB1.width=310 AB1.tooltip = Blabla filesystem browser AB2.type = openbrowser AB2.label = Choose a master playlist file AB2.width=310 AB2.tooltip = Blabla filesystem browser ...and so on for the rest of the array: What I am using to write to the text file at the moment is: count=1 saveIFS="$IFS" IFS=$'\n' array=($(<TEST.txt)) IFS="$saveIFS" for i in "${array[@]}"; do declare AD$count="$i"; ((count++)); done for i in "${array[@]}"; do echo "AD$count".type = openbrowser "AD$count".label = Choose a master playlist file \n "AD$count".width=310 \n "AD$count".tooltip = Blabla filesystem browser \n" >> long.txt; done However \n doesn't produce a newline in the text file, and I am pretty sure there is a alot nicer way todo this, ideas?

  • Creating and writing file from a FileOutputStream in Java

    - by Althane
    Okay, so I'm working on a project where I use a Java program to initiate a socket connection between two classes (a FileSender and FileReceiver). My basic idea was that the FileSender would look like this: try { writer = new DataOutputStream(connect.getOutputStream()); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } //While we have bytes to send while(filein.available() >0){ //We write them out to our buffer writer.write(filein.read(outBuffer)); writer.flush(); } //Then close our filein filein.close(); //And then our socket; connect.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); The constructor contains code that checks to see if the file exists, and that the socket is connected, and so on. Inside my FileReader is this though: input = recvSocket.accept(); BufferedReader br = new BufferedReader(new InputStreamReader(input.getInputStream())); FileOutputStream fOut= new FileOutputStream(filename); String line = br.readLine(); while(line != null){ fOut.write(line.getBytes()); fOut.flush(); line = br.readLine(); } System.out.println("Before RECV close statements"); fOut.close(); input.close(); recvSocket.close(); System.out.println("After RECV clsoe statements"); All inside a try-catch block. So, what I'm trying to do is have the FileSender reading in the file, converting to bytes, sending and flushing it out. FileReceiver, then reads in the bytes, writes to the fileOut, flushes, and continues waiting for more. I make sure to close all the things that I open, so... here comes the weird part. When I try and open the created text file in Eclipse, it tells me "An SWT error has occured ... recommended to exit the workbench... see .log for more details.". Another window pops up saying "Unhandled event loop exception, (no more handles)". However, if I try to open the sent text file in notepad2, I get ThisIsASentTextfile Which is good (well, minus the fact that there should be line breaks, but I'm working on that...). Does anyone know why this is happening? And while we're checking, how to add the line breaks? (And is this a particularly bad way to transfer files over java without getting some other libraries?)

    This is the same question as this: http://stackoverflow.com/questions/2890620/jquery-running-a-function-in-a-context-and-adding-to-a-variable But that question was poorly posed. Trying again, I'm trying to do something like this: I have a bunch of elements I want to grab data from, the data is in the form of classes of the element children. <div id='container'> <span class='a'></span> <span class='b'></span> <span class='c'></span> </div> <div id='container2'> <span class='1'></span> <span class='2'></span> <span class='3'></span> </div> I have a method like this: jQuery.fn.grabData = function(expr) { return this.each(function() { var self = $(this); self.find("span").each(function (){ var info = $(this).attr('class'); collection += info; }); }); }; I to run the method like this: var collection = ''; $('#container').grabData(); $('#container2').grabData(); The collection should be adding to each other so that in the end I get this console.log(collection); : abc123 But collection is undefined in the method. How can I let the method know which collection it should be adding to? Thanks.
