  • storing user info/pass in web.config authentication

    - by Tomaszewski
    Hello, I am trying to write a simple internal app with some simple authentication. I'm also trying to make this quick and learn about the forms authentication via web.config. So i have my authentication working if I hard code my 'user name' and 'password' into C# code and do a simple conditional. However, I'm having a tough time storing the a user/pass to be checked against in the web.config file. The MSDN manual says to put this into the web.config: <authentication mode="Forms"> <forms loginUrl="login.aspx"> <credentials passwordFormat="SHA1"> <user name="user1" password="27CE4CA7FBF00685AF2F617E3F5BBCAFF7B7403C" /> <user name="user2" password="D108F80936F78DFDD333141EBC985B0233A30C7A" /> <user name="user3" password="7BDB09781A3F23885CD43177C0508B375CB1B7E9"/> </credentials> </forms> </authentication> However, the minute I add 'credentials' into the 'authentication' section, I get this error: Server Error in '/' Application. Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: Unrecognized element 'credentials'. Source Error: Line 44: <authentication mode="Forms"> Line 45: <forms loginUrl="login.aspx" /> Line 46: <credentials> Line 47: Line 48: </credentials> Source File: C:\inetpub\wwwroot\asp\projects\passwordCatalog\passwordCatalog\web.config Line: 46 So my question is, how and where would I add the following in the web.config file? <credentials passwordFormat="SHA1"> <user name="johndoe" password="mypass123" /> </credentials>

  • Perl script matching a certain patern

    - by kivien
    Assuming the file.txt is as follows:- John Depp is a great guy. He is very inteligent. He can do anything. Come and meet John Depp. The perl code is as follows:- open ( FILE, "file.txt" ) || die "can't open file!"; @lines = <FILE>; close (FILE); $string = "John Depp"; foreach $line (@lines) { if ($line =~ $string) { print "$line"; } } The output is going to be first and fourth line. I want to make it working for the file having random line breaks rather than one English sentence per line. I mean it should also work for the following:- John Depp is a great guy. He is very inteligent. He can do anything. Come and meet John Depp. The output should be first and fourth sentence. Any ideas please?

  • Parsing unicode XML with Python SAX on App Engine

    - by Derek Dahmer
    I'm using xml.sax with unicode strings of XML as input, originally entered in from a web form. On my local machine (python 2.5, using the default xmlreader expat, running through app engine), it works fine. However, the exact same code and input strings on production app engine servers fail with "not well-formed". For example, it happens with the code below: from xml import sax class MyHandler(sax.ContentHandler): pass handler = MyHandler() # Both of these unicode strings return 'not well-formed' # on app engine, but work locally xml.parseString(u"<a>b</a>",handler) xml.parseString(u"<!DOCTYPE a[<!ELEMENT a (#PCDATA)> ]><a>b</a>",handler) # Both of these work, but output unicode xml.parseString("<a>b</a>",handler) xml.parseString("<!DOCTYPE a[<!ELEMENT a (#PCDATA)> ]><a>b</a>",handler) resulting in the error: File "<string>", line 1, in <module> File "/base/python_dist/lib/python2.5/xml/sax/__init__.py", line 49, in parseString parser.parse(inpsrc) File "/base/python_dist/lib/python2.5/xml/sax/expatreader.py", line 107, in parse xmlreader.IncrementalParser.parse(self, source) File "/base/python_dist/lib/python2.5/xml/sax/xmlreader.py", line 123, in parse self.feed(buffer) File "/base/python_dist/lib/python2.5/xml/sax/expatreader.py", line 211, in feed self._err_handler.fatalError(exc) File "/base/python_dist/lib/python2.5/xml/sax/handler.py", line 38, in fatalError raise exception SAXParseException: <unknown>:1:1: not well-formed (invalid token) Any reason why app engine's parser, which also uses python2.5 and expat, would fail when inputting unicode?

  • Upload image from J2ME client to a Servlet

    - by Akash
    I want to send an image from a J2ME client to a Servlet. I am able to get a byte array of the image and send it using HTTP POST. conn = (HttpConnection) Connector.open(url, Connector.READ_WRITE, true); conn.setRequestMethod(HttpConnection.POST); conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); os.write(bytes, 0, bytes.length); // bytes = byte array of image This is the Servlet code: String line; BufferedReader r1 = new BufferedReader(new InputStreamReader(in)); while ((line = r1.readLine()) != null) { System.out.println("line=" + line); buf.append(line); } String s = buf.toString(); byte[] img_byte = s.getBytes(); But the problem I found is, when I send bytes from the J2ME client, some bytes are lost. Their values are 0A and 0D hex. Exactly, the Carriage Return and Line Feed. Thus, either POST method or readLine() are not able to accept 0A and 0D values. Any one have any idea how to do this, or how to use any another method?

  • Winforms: How to speed up Invalidate()?

    - by Pedery
    I'm developing a retained mode drawing application in GDI+. The application can draw simple shapes to a canvas and perform basic editing. The math that does this is optimized to the last byte and is not an issue. I'm drawing on a panel that is using the built-in Controlstyles.DoubleBuffer. Now, my problem arises if I run my app maximized on a big monitor (HD in my case). If I try to draw a line from one corner of the (big) canvas to the diagonally oposite other, it will start to lag and the CPU goes high up. Each graphical object in my app has a boundingbox. Thus, when I invalidate the boundingbox of a line that goes from one corner of the maximized app to the oposite diagonal one, that boundingbox is virtually as big as the canvas. When a user is drawing a line, this invalidation of the boundingbox thus happens on the mousemove event, and there is a clear lag visible. This lag also exists if the line is the only object on the canvas. I've tried to optimize this in many ways. If I draw a shorter line, the CPU and the lag goes down. If I remove the Invalidate() and keep all other code, the app is quick. If I use a Region (that only spans the figure) to invalidate instead of the boundingbox, it is just as slow. If I split the boundingbox into a range of smaller boxes that lie back to back, thus reducing the invalidation area, no visible performance gain can be seen. Thus I'm at a loss here. How can I speed up the invalidation? On a side note, both Paint.Net and Mspaint suffers from the same shortcommings. Word and PowerPoint however, seem to be able to paint a line as described above with no lag and no CPU load at all. Thus it's possible to achieve the desired results, the question is how?

  • send Image from J2ME to SERVLET

    - by Akash
    Hi, I want to send Image from J2ME to SERVLET. I am able to convert image into Byte Array, and send by Http POST. I have coded as : - From Mobile : conn = (HttpConnection)Connector.open(url,Connector.READ_WRITE,true); conn.setRequestMethod(HttpConnection.POST); conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); os.write(bytes, 0, bytes.length);//bytes = byte array of image At servlet : String line; BufferedReader r1 = new BufferedReader(new InputStreamReader(in)); while ((line = r1.readLine()) != null) { System.out.println("line=" + line); buf.append(line); } String s = buf.toString(); byte[] img_byte = s.getBytes(); Now d problem I found is, when I send Bytes from Mob App, some bytes are LOST , whose value is 0A and 0D-Hex ... Exactly, Cr- Carriage Return & Lf- Line Feed... It means, POST method OR readLine() not able to accept 0A & 0D value... And so I come to know that, LOST bytes are 0A and 0D occurrence in image's byte array.... Any one have any idea, how to do this, or how to use any another method..... Thanks -Akash

  • Shared Server Dreamhost

    - by Jseb
    I am trying to install an app on a shared server. If i understand properly because i am using a shared server, and that Dreamhost doesn't suppose rails 3.2.8 I must use FCGI, although i am not sure how to install and to make it run properly. From this tutorial http://wiki.dreamhost.com/Rails_3. To my understand here what I did, In dreamhost, activate PHP 5.x.x FastCGI and made sure Phusion Passenger is unchecked Create an app on my localmachine Because rails doesn't create a dispatch and access file i create the two following file in my /public folder dispatch.fcgi #!/home/username/.rvm/rubies/ruby-1.9.3-p327/bin/ruby ENV['RAILS_ENV'] ||= 'production' ENV['HOME'] ||= `echo ~`.strip ENV['GEM_HOME'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327') ENV['GEM_PATH'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327') + ":" + File.expand_path('~/.rvm/gems/ruby 1.9.3-p327@global') require 'fcgi' require File.join(File.dirname(__FILE__), '../config/environment') class Rack::PathInfoRewriter def initialize(app) @app = app end def call(env) env.delete('SCRIPT_NAME') parts = env['REQUEST_URI'].split('?') env['PATH_INFO'] = parts[0] env['QUERY_STRING'] = parts[1].to_s @app.call(env) end end Then created the file .htaccess <IfModule mod_fastcgi.c> AddHandler fastcgi-script .fcgi </IfModule> <IfModule mod_fcgid.c> AddHandler fcgid-script .fcgi </IfModule> Options +FollowSymLinks +ExecCGI RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ dispatch.fcgi/$1 [QSA,L] ErrorDocument 500 "Rails application failed to start properly" Uploaded to a folder and pointed to the public folder in dreamhost Made sure dispatch.fcgi has 777 for write ssh and run the following command in the public folder : ./dispatch.fcgi Crossing my finger but it doesn't work I get the following errors ./dispatch.fcgi: line 1: ENV[RAILS_ENV]: command not found ./dispatch.fcgi: line 1: =: command not found ./dispatch.fcgi: line 2: ENV[HOME]: command not found ./dispatch.fcgi: line 2: =: command not found ./dispatch.fcgi: line 3: syntax error near unexpected token (' ./dispatch.fcgi: line 3:ENV['GEM_HOME'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327')' Doing wrong???

  • Java Sound API: Capturing sound output from a Target Port

    - by Kyle Kampy
    I'm writing a simple piece of software that streams audio over LAN. I have all of the network parts implemented, but what I'm stumbling on is using the Java Sound API. I have successfully captured audio from the microphone, and line-in, but I can't seem to capture from any target ports, like the speakers. My question is, is it possible to capture from the Master target port? Here is the piece of code that works on initializing the line. private boolean startCapture(){ try{ DataLine.Info info = new DataLine.Info( TargetDataLine.class, format); line = (TargetDataLine)AudioSystem.getLine(info); audioBuffer = new byte[bufferSize]; line.open(format); line.start(); return true; }catch(Exception e){ System.out.println("Exception thrown when capturing audio:\n" + e); return false; } } Running the code like this will just use the microphone as my line. Here is info about my sound system. Most important is probably the fact that I'm running Linux. Thanks in advance for any and all help you can give me.

  • Having trouble passing text from MySQL to a Javascript function using PHP

    - by Nathan Brady
    So here's the problem. I have data in a MySQL DB as text. The data is inserted via mysql_real_escape_string. I have no problem with the data being displayed to the user. At some point I want to pass this data into a javascript function called foo. // This is a PHP block of code // $someText is text retrieved from the database echo "<img src=someimage.gif onclick=\"foo('{$someText}')\">"; If the data in $someText has line breaks in it like: Line 1 Line 2 Line 3 The javascript breaks because the html output is <img src=someimage.gif onclick="foo('line1 line2 line3')"> So the question is, how can I pass $someText to my javascript foo function while preserving line breaks and carriage returns but not breaking the code? =========================================================================================== After using json like this: echo "<img src=someimage.gif onclick=\"foo($newData)\">"; It is outputting HTML like this: onclick="foo("line 1<br \/>\r\nline 2");"> Which displays the image followed by \r\nline 2");"

  • Check if the internet cannot be accessed in Python

    - by Sridhar Ratnakumar
    I have an app that makes a HTTP GET request to a particular URL on the internet. But when the network is down (say, no public wifi - or my ISP is down, or some such thing), I get the following traceback at urllib.urlopen: 70, in get u = urllib2.urlopen(req) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/urllib2.py", line 126, in urlopen return _opener.open(url, data, timeout) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/urllib2.py", line 391, in open response = self._open(req, data) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/urllib2.py", line 409, in _open '_open', req) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/urllib2.py", line 369, in _call_chain result = func(*args) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/urllib2.py", line 1161, in http_open return self.do_open(httplib.HTTPConnection, req) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/urllib2.py", line 1136, in do_open raise URLError(err) URLError: <urlopen error [Errno 8] nodename nor servname provided, or not known> I want to print a friendly error to the user telling him that his network maybe down instead of this unfriendly "nodename nor servname provided" error message. Sure I can catch URLError, but that would catch every url error, not just the one related to network downtime. I am not a purist, so even an error message like "The server example.com cannot be reached; either the server is indeed having problems or your network connection is down" would be nice. How do I go about selectively catching such errors? (For a start, if DNS resolution fails at urllib.urlopen, that can be reasonably assumed as network inaccessibility? If so, how do I "catch" it in the except block?)

  • Readability and IF-block brackets: best practice

    - by MasterPeter
    I am preparing a short tutorial for level 1 uni students learning JavaScript basics. The task is to validate a phone number. The number must not contain non-digits and must be 14 digits long or less. The following code excerpt is what I came up with and I would like to make it as readable as possible. if ( //set of rules for invalid phone number phoneNumber.length == 0 //empty || phoneNumber.length > 14 //too long || /\D/.test(phoneNumber) //contains non-digits ) { setMessageText(invalid); } else { setMessageText(valid); } A simple question I can not quite answer myself and would like to hear your opinions on: How to position the surrounding (outermost) brackets? It's hard to see the difference between a normal and a curly bracket. Do you usually put the last ) on the same line as the last condition? Do you keep the first opening ( on a line by itself? Do you wrap each individual sub-condition in brackets too? Do you align horizontally the first ( with the last ), or do you place the last ) in the same column as the if? Do you keep ) { on a separate line or you place the last ) on the same line with the last sub-condition and then place the opening { on a new line? Or do you just put the ) { on the same line as the last sub-condition? Community wiki. EDIT Please only post opinions regarding the usage and placement of brackets. The code needs not be re-factored. This is for people who have only been introduced to JavaScript a couple of weeks ago. I am not asking for opinions how to write the code so it's shorter or performs better. I would only like to know how do you place brackets around IF-conditions.

  • wamp cannot load mysqli extension

    - by localhost
    WAMP installed fine, no problems, BUT... When going to phpMyAdmin, I get the error from phpMyAdmin as follows: "Cannot load mysqli extension. Please check your PHP configuration". Also, phpMyAdmin documentation explains this error message as follows: "To connect to a MySQL server, PHP needs a set of MySQL functions called "MySQL extension". This extension may be part of the PHP distribution (compiled-in), otherwise it needs to be loaded dynamically. Its name is probably mysql.so or php_mysql.dll. phpMyAdmin tried to load the extension but failed. Usually, the problem is solved by installing a software package called "PHP-MySQL" or something similar." Finally, the apache_error.log file has the following PHP warnings (see the mySQL warning): PHP Warning: Zend Optimizer does not support this version of PHP - please upgrade to the latest version of Zend Optimizer in Unknown on line 0 PHP Warning: Zend Platform does not support this version of PHP - please upgrade to the latest version of Zend Platform in Unknown on line 0 PHP Warning: Zend Debug Server does not support this version of PHP - please upgrade to the latest version of Zend Debug Server in Unknown on line 0 PHP Warning: gd wrapper does not support this version of PHP - please upgrade to the latest version of gd wrapper in Unknown on line 0 PHP Warning: java wrapper does not support this version of PHP - please upgrade to the latest version of java wrapper in Unknown on line 0 PHP Warning: mysql wrapper does not support this version of PHP - please upgrade to the latest version of mysql wrapper in Unknown on line 0 So, for some reason PHP is not recognizing the mysql extension. Anyone know why? Any solution or workaround?

  • sorl-thumbnail unit tests fail by 1 pixel (!)

    - by stevejalim
    Hi I'm using sorl-thumbnail in a Django 1.2 (currently 1.2 RC) project and getting a surprising failure of four of sorl's built-in unit tests. Essentially, the resized images are all 1px shorter than the unit tests expect them to be. See below for details I'm developing on OSX 10.5.8 (not Snow Leopard) with Python 2.5.1 (r251:54863, Feb 6 2009, 19:02:12) and PIL 1.1.6. Any thoughts what might be up?

  • Python regex look-behind requires fixed-width pattern

    - by invictus
    Hi When trying to extract the title of a html-page I have always used the following regex: (?<=<title.*>)([\s\S]*)(?=</title>) Which will extract everything between the tags in a document and ignore the tags themselves. However, when trying to use this regex in Python it raises the following Exception: Traceback (most recent call last): File "test.py", line 21, in pattern = re.compile('(?<=)([\s\S]*)(?=)') File "C:\Python31\lib\re.py", line 205, in compile return _compile(pattern, flags) File "C:\Python31\lib\re.py", line 273, in _compile p = sre_compile.compile(pattern, flags) File "C:\Python31\lib\sre_compile.py", line 495, in compile code = _code(p, flags) File "C:\Python31\lib\sre_compile.py", line 480, in _code _compile(code, p.data, flags) File "C:\Python31\lib\sre_compile.py", line 115, in _compile raise error("look-behind requires fixed-width pattern") sre_constants.error: look-behind requires fixed-width pattern The code I am using is: pattern = re.compile('(?<=<title.*>)([\s\S]*)(?=</title>)') m = pattern.search(f) if I do some minimal adjustments it works: pattern = re.compile('(?<=<title>)([\s\S]*)(?=</title>)') m = pattern.search(f) This will, however, not take into account potential html titles that for some reason have attributes or similar. Anyone know a good workaround for this issue? Any tips are appreciated.

  • Print a string that contains a certain pattern in Java

    - by jjpotter
    I am trying to find a regular expression within a line of a .csv file, so I can eventually save all the matches to another file, and lose all the other junk. So a line in my file might look like: MachineName,User,IP,VariableData,Location The VariableData is what I want to match, and if there's a match, print the line. I am using a pattern for this because I only want 3 out of 10 of variations of VariableData, and out of those 3, they are numbered differently(example, "pc104, pccrt102, pccart65"). I am trying to do this using the Scanner Class and keeping it simple as possible so I can understand it. Here is where I was heading with this...(the pattern isn't complete, just have it like this for testing). import java.io.File; import java.util.Scanner; import java.util.regex.Pattern; public class pcv { public static void main(String[] args) { File myFile = new File("c:\\temp\\report.csv"); Pattern myPat = Pattern.compile("pc"); try{ Scanner myScan = new Scanner(myFile); while(myScan.hasNext()){ if(myScan.hasNext(myPat)){ System.out.println("Test"); } } }catch(Exception e){ } } } This code loops, im guessing the .hasNext() methods are resetting themselves. I've played around with the Matcher class a little bit, but only found a way to match the expression but not get the whole line. My other throught was maybe somehow count the line that contains the pattern, then go back and print the line that corresponds to the counts.

  • Does anyone know how to detect whether a Windows Service is running through Java

    - by GKelly
    There's plenty of information on running Java apps as services, but I need to know how to detect whether a windows service is running or not. Does anyone know how??? At the DOS prompt, I can run: tasklist /svc|findstr "NonRunningService" echo Return code for N onRunningService is %ERRORLEVEL% tasklist /svc|findstr "RunningService" echo Return code for RunningService is %ERRORLEVEL% I get the following: Return code for NonRunningService is 1 Return code for RunningService is 0 In code, I have: int retCode = Runtime.getRuntime.exec("tasklist /svc|findstr \"NonRunningService\"").waitFor(); System.out.println("Return code for NonRunningService is " + retCode); retCode = Runtime.getRuntime.exec("tasklist /svc|findstr \"RunningService\"").waitFor(); System.out.println("Return code for RunningService is " + retCode); I get the following output Return code for NonRunningService is 1 Return code for RunningService is 1 According to the JavaDocs, the waitFor() should block until the process finishes, and give me the exit value of the process. I've also tried using the Process/ProcessBuilder command line calls: //'tasklist /nh /fi "SERVICES eq RunningService"' will return a line for // each running service of the requested type. Process p1 = new ProcessBuilder("tasklist", "/nh", "/fi" "SERVICES eq RunningService").start(); p1.waitFor(); BufferedReader is = new BufferedReader(new InputStreamReader(p1.getInputStream())); String line = is.readLine(); System.out.println("Service - " + line); System.out.println("Running? ", (line==null?"No":"Yes"); gives: Service - Running? No even when I get lines in the output at the command line!

  • High performance text file parsing in .net

    - by diamandiev
    Here is the situation: I am making a small prog to parse server log files. I tested it with a log file with several thousand requests (between 10000 - 20000 don't know exactly) What i have to do is to load the log text files into memory so that i can query them. This is taking the most resources. The methods that take the most cpu time are those (worst culprits first): string.split - splits the line values into a array of values string.contains - checking if the user agent contains a specific agent string. (determine browser ID) string.tolower - various purposes streamreader.readline - to read the log file line by line. string.startswith - determine if line is a column definition line or a line with values there were some others that i was able to replace. For example the dictionary getter was taking lots of resources too. Which i had not expected since its a dictionary and should have its keys indexed. I replaced it with a multidimensional array and saved some cpu time. Now i am running on a fast dual core and the total time it takes to load the file i mentioned is about 1 sec. Now this is really bad. Imagine a site that has tens of thousands of visits a day. It's going to take minutes to load the log file. So what are my alternatives? If any, cause i think this is just a .net limitation and i can't do much about it.

  • In asp.Net, writing code in the control tag generates compile error

    - by Nour Sabouny
    Hi this is really strange !! But look at the following asp code: <div runat="server" id="MainDiv"> <%foreach (string str in new string[]{"First#", "Second#"}) { %> <div id="<%=str.Replace("#","div") %>"> </div> <%} %> </div> now if you put this code inside any web page (and don't worry about the moral of this code, I made it just to show the idea) you'll get this error : Compiler Error Message: CS1518: Expected class, delegate, enum, interface, or struct Of course the error has nothing to do with the real problem, I searched for the code that was generated by asp.net and figured out the following : private void @__RenderMainDiv(System.Web.UI.HtmlTextWriter @__w, System.Web.UI.Control parameterContainer) { @__w.Write("\r\n "); #line 20 "blabla\blabla\Default.aspx" foreach (string str in new string[] { "First#", "Second#" }) { #line default #line hidden @__w.Write("\r\n <div id=\""); #line 22 "blabla\blabla\Default.aspx" @__w.Write(str.Replace("#", "div")); #line default #line hidden @__w.Write("\">\r\n "); } This is the code that was generated from the asp page and this is the method that is meant to render our div (MainDiv), I found out that there is a missing bracket "}" that closes the method or the (for loop). now the problem has three parts: 1- first you should have a server control (in our situation is the MainDiv) and I'm not sure if it is only the div tag. 2- HTML control inside the server control and a code inside it using the double quotation mark ( for example <div id="<%=str instead of <div id='<%=str. 3-Any keyword which has block brackets e.g.:for{},while{},using{}...etc. now removing any part, will solve the problem !!! how is this happening ?? any ideas ? BTW: please help me to make the question more obvious, because I couldn't find the best words to describe the problem.

  • Python halts while iteratively processing my 1GB csv file

    - by Dan
    I have two files: metadata.csv: contains an ID, followed by vendor name, a filename, etc hashes.csv: contains an ID, followed by a hash The ID is essentially a foreign key of sorts, relating file metadata to its hash. I wrote this script to quickly extract out all hashes associated with a particular vendor. It craps out before it finishes processing hashes.csv stored_ids = [] # this file is about 1 MB entries = csv.reader(open(options.entries, "rb")) for row in entries: # row[2] is the vendor if row[2] == options.vendor: # row[0] is the ID stored_ids.append(row[0]) # this file is 1 GB hashes = open(options.hashes, "rb") # I iteratively read the file here, # just in case the csv module doesn't do this. for line in hashes: # not sure if stored_ids contains strings or ints here... # this probably isn't the problem though if line.split(",")[0] in stored_ids: # if its one of the IDs we're looking for, print the file and hash to STDOUT print "%s,%s" % (line.split(",")[2], line.split(",")[4]) hashes.close() This script gets about 2000 entries through hashes.csv before it halts. What am I doing wrong? I thought I was processing it line by line. ps. the csv files are the popular HashKeeper format and the files I am parsing are the NSRL hash sets. http://www.nsrl.nist.gov/Downloads.htm#converter UPDATE: working solution below. Thanks everyone who commented! entries = csv.reader(open(options.entries, "rb")) stored_ids = dict((row[0],1) for row in entries if row[2] == options.vendor) hashes = csv.reader(open(options.hashes, "rb")) matches = dict((row[2], row[4]) for row in hashes if row[0] in stored_ids) for k, v in matches.iteritems(): print "%s,%s" % (k, v)
