    - by santa

  • HTML Purifier: Removing an element conditionally based on its attributes

    - by pinkgothic
    As per the HTML Purifier smoketest, 'malformed' URIs are occasionally discarded to leave behind an attribute-less anchor tag, e.g. <a href="javascript:document.location='http://www.google.com/'">XSS</a> becomes <a>XSS</a> ...as well as occasionally being stripped down to the protocol, e.g. <a href="http://1113982867/">XSS</a> becomes <a href="http:/">XSS</a> While that's unproblematic, per se, it's a bit ugly. Instead of trying to strip these out with regular expressions, I was hoping to use HTML Purifier's own library capabilities / injectors / plug-ins / whathaveyou. Point of reference: Handling attributes Conditionally removing an attribute in HTMLPurifier is easy. Here the library offers the class HTMLPurifier_AttrTransform with the method confiscateAttr(). While I don't personally use the functionality of confiscateAttr(), I do use an HTMLPurifier_AttrTransform as per this thread to add target="_blank" to all anchors. // more configuration stuff up here $htmlDef = $htmlPurifierConfiguration->getHTMLDefinition(true); $anchor = $htmlDef->addBlankElement('a'); $anchor->attr_transform_post[] = new HTMLPurifier_AttrTransform_Target(); // purify down here HTMLPurifier_AttrTransform_Target is a very simple class, of course. class HTMLPurifier_AttrTransform_Target extends HTMLPurifier_AttrTransform { public function transform($attr, $config, $context) { // I could call $this->confiscateAttr() here to throw away an // undesired attribute $attr['target'] = '_blank'; return $attr; } } That part works like a charm, naturally. Handling elements Perhaps I'm not squinting hard enough at HTMLPurifier_TagTransform, or am looking in the wrong place(s), or generally amn't understanding it, but I can't seem to figure out a way to conditionally remove elements. Say, something to the effect of: // more configuration stuff up here $htmlDef = $htmlPurifierConfiguration->getHTMLDefinition(true); $anchor = $htmlDef->addElementHandler('a'); $anchor->elem_transform_post[] = new HTMLPurifier_ElementTransform_Cull(); // add target as per 'point of reference' here // purify down here With the Cull class extending something that has a confiscateElement() ability, or comparable, wherein I could check for a missing href attribute or a href attribute with the content http:/. HTMLPurifier_Filter I understand I could create a filter, but the examples (Youtube.php and ExtractStyleBlocks.php) suggest I'd be using regular expressions in that, which I'd really rather avoid, if it is at all possible. I'm hoping for an onboard or quasi-onboard solution that makes use of HTML Purifier's excellent parsing capabilities. Returning null in a child-class of HTMLPurifier_AttrTransform unfortunately doesn't cut it. Anyone have any smart ideas, or am I stuck with regexes? :)

  • Using Performance Monitor To Get IIS7 Response Turnaround Time

    - by alphadogg
    I have a MVC2 web application on W2KR2/IIS7 that I'd like to benchmark/monitor. Some XHR requests by a browser-based client are suddenly taking 8-10 sec when they used to take much less time (as per Chrome Developer Tool timings). The underlying SQL Server queries, using the same params, runs in 1.4s according to total execution time client statistics from SSMS. I'm assuming that there are various counters that can specifically dissect time taken/waiting/processing between IIS7 itself and the web application? For example, can I check how long it takes to get a response from IIS7 app and DB? How about how long it takes to serve IIS7?

  • Virtual server hardware to simulate 3-4 node web farm

    - by frankadelic
    I would like to get a dedicated server to run VMWare, VirtualBox, or similar. On this box, I would like to host 3-4 virtual instances of Linux, to act as nodes in a web farm. Performance is not that important, this would only be for testing and experimenting. I need something sub $1000 (including tax/shipping). Can someone recommend a pre-built server that would do the trick? I am pretty ignorant of hardware so building one is not going to work for me. Also, would I need multiple network cards to simulate a web farm or can the virtualization software handle that for me. Thanks

  • C# - update variable based upon results from backgroundworker

    - by Bruce
    I've got a C# program that talks to an instrument (spectrum analyzer) over a network. I need to be able to change a large number of parameters in the instrument and read them back into my program. I want to use backgroundworker to do the actual talking to the instrument so that UI performance doesn't suffer. The way this works is - 1) send command to the instrument with new parameter value, 2) read parameter back from the instrument so I can see what actually happened (for example, I try to set the center frequency above the max that the instrument will handle and it tells me what it will actually handle), and 3) update a program variable with the actual value received from the instrument. Because there are quite a few parameters to be updated I'd like to use a generic routine. The part I can't seem to get my brain around is updating the variable in my code with what comes back from the instrument via backgroundworker. If I used a separate RunWorkerCompleted event for each parameter I could hardwire the update directly to the variable. I'd like to come up with a way of using a single routine that's capable of updating any of the variables. All I can come up with is passing a reference number (different for each parameter) and using a switch statement in the RunWorkerCompleted handler to direct the result. There has to be a better way. Thanks for your help.

  • How can I dispatch an PropertyChanged event from a subscription to an Interval based IObservable

    - by James Hay
    I'm getting an 'UnauthorizedAccesExpection - Invalid cross-thread access' exception when I try to raise a PropertyChanged event from within a subscription to an IObservable collection created through Observable.Interval(). With my limited threading knowledge I'm assuming that the interval is happening on some other thread while the event wants to happen on the UI thread??? An explanation of the problem would be very useful. The code looks a little like: var subscriber = Observable.Interval(TimeSpan.FromSeconds(1)) .Subscribe(x => { Prop = x; // setting property raises a PropertyChanged event }); Any solutions?

  • LINQ-to-XML selection based on node values, newbie question

    - by mmcglynn
    Given the following XML, I would like to return all eventtitles where the eventtype id = 23. My current query only looks at the first eventtype, so returns the wrong result. <event> <eventtitle>Garrison Keillor</eventtitle> <eventtypes> <eventtype id="24"/> <eventtype id="23"/> </eventtypes> </event> <event> <eventtitle>Joe Krown Trio featuring Walter Wolfman Washington</eventtitle> <eventtypes> <eventtype id="23"/> </eventtypes> </event> LINQ query: Dim query = _ From c In calXML...<event> _ Where c...<eventtypes>.<eventtype>.@id = "23" _ Select c.<eventtitle>.Value, c.<eventlocation>.Value For Each item In query Response.Write("<h3>" & item.eventtitle & "</h3>") Response.Write(item.eventlocation & "<br />") Next

  • Adding IP address to OpenVZ VPS (OpenVZ Web Panel)

    - by andy
    I apologise if I sound at all dumb. This is my first dedicated server having used a VPS for over a year and I'm trying to setup a VPS on this new server. I purchased a subnet from my hosting provider that I believe allows me 6 usable IP addresses: 177.xx.xxx.201 - 177.xx.xxx.206 The subnet address looks like this: 177.xx.xxx.200/29. I've gone on my server and added them like it said on a wiki like so: ip addr add 177.**.***.201/29 dev eth0 I done that for all six and now when I go to them in the browser they point to my server. The problem is, I'm using OpenVZ web panel to create VMs (http://code.google.com/p/ovz-web-panel/) so I created a VM and assigned one of those IPs to it. However when SSHing to that IP it SSH's to the dedicated server and not the VM. Am I missing something?

  • WSS Web application and IIS Website differences

    - by chaitanya
    Can somebody explain briefly the differences between a "WSS Web Application" and a normal "IIS Website"? I have read that a WSS web application is a "special" IIS Website with WSS featured. I also know that the content of a web application is stored in an SQL Server Website(called the content database) whereas an IIS Website stores it on a hard disk on the server. A point-by-point difference would be appreciated.

  • How can I get Opera speed-dial and password management features in other browsers?

    - by Howard Guo
    I heavily rely on Opera's speed dial and password management features. Lack of these two features is really stopping me from switching to another web browser such as Chrome or Firefox. Opera's password management has two unique characteristics which I rely on heavily: It saves passwords on all pages, (apparently) despite the page's meta data asking not to save passwords. It offers keyboard shortcut and button to automatically fill in username/passwords and all other fields in a login form, then automatically submit the form. (So I'm only one key/click away from logging into a website) How can I get those functions in other browsers? Thank you! Edit: Reason being that I use other web browsers at work and I wish they could have those functions.

  • Photo/Video gallery for Ubuntu web server

    - by Andrew
    I'm trying to have a gallery that can display images as well as videos for visitors to my web server. I'm running Ubuntu 12.10, and have Apache installed. All my images and videos are in /var/www/media. I've taken a look at bbgallery, which is simple enough for me, but I don't think it supports video. I've also looked at Single File PHP Gallery, but it doesn't support video. Does anyone know of a gallery that supports video as well, which I can use for my web server? EDIT: I do not have a database.

  • AppleScript to open URL in Safari crashes for Flash-based websites

    - by Mark
    I'm trying to open a URL in Safari. It works fine for websites without Flash embedded, but crashes Safari for Flash sites. Example (this WORKS): tell application "Safari" to open location "http://google.com" This CRASHES when Safari is not already running: tell application "Safari" to open location "http://grooveshark.com" Two things I noticed: Safari only crashes for websites with embedded Flash The script above only crashes if a new instance of Safari is created (i.e. Safari was not running before) From the second observation I assume that it could be a permission issue of some sort. Maybe the Safari instance launched from the AppleScript has a problem loading plugins?

  • gwt rounded panel (standards based widget akin to DecoratorPanel)

    - by brad
    I'm trying to write an app that uses rounded corners for framing the app. I've found a package on google code that has a RoundedLinePanel and it seems to work... kind of. I'm wondering a few things. Is this what people are using for creating divs with round corners in GWT? The release notes say it hasn't changed in almost a year. Also, I can't seem to set a fixed height of this div (setHeight sets it on the wrapper div, not the inner one). so it's not useful to me as I have a fixed height app. Finally, if anyone can suggest a better mechanism for creating rounded corner divs in GWT I'm all ears.

  • Using awstats with a round-robin DNS configuration

    - by Shaun
    I have a website with multiple web servers whose access is controlled via a round-robin DNS. We currently use Google Analytics for site traffic monitoring but were looking to move to awstats due to concerns of inaccuracy with Google Analytics and using third-party trackers in general. I have a little experience with awstats and I know it gets its information from parsing server logs. How would this work when you have multiple web servers logging independently to separate locations? Is this supported with awstats? Is there an alternative I could use to track traffic activity directly on my servers?

  • Restrict RDP port based on a Dynamic DNS

    - by webnoob
    Hi All, I want to set a restriction on my firewall (windows firewall on windows 2008) to only allow connections from a certain dynamic DNS. Is this possible? The reason I ask is that this would allow us to just change the IP on the dynamic DNS if our IP changes and means we won't get locked out of RDP. This also allows me to RDP in from other locations that have IP's that are not static by just changing the IP against the DNS. Any ideas. Thanks in advance.

  • Setting ItemTemplate based on CheckBox value

    - by ph0enix
    I have a DataTemplate which contains a CheckBox and ListBox. When the CheckBox is checked, I want to change the ItemTemplate property on the ListBox to change the appearance of each item. Right now, it looks like this: <DataTemplate DataType={x:Type MyViewModel}> <DockPanel> <CheckBox DockPanel.Dock="Bottom" Content="Show Details" HorizontalAlignment="Right" IsChecked="{Binding ShowDetails}" Margin="0 5 10 5" /> <ListBox ItemsSource="{Binding Items}" ItemTemplate="{StaticResource SimpleItemTemplate}" Margin="10 0 10 5"> <ListBox.Triggers> <DataTrigger Binding="{Binding ShowDetails}" Value="True"> <Setter Property="ItemTemplate" Value="{StaticResource DetailedItemTemplate}" /> </DataTrigger> </ListBox.Triggers> </ListBox> </DockPanel> </DataTemplate> However, when I try to compile, I get the following error messages: Value 'ItemTemplate' cannot be assigned to property 'Property'. Invalid PropertyDescriptor value. and Cannot find the static member 'ItemTemplateProperty' on the type 'ContentPresenter'. I'm still fairly new to WPF, so perhaps there is something I'm not quite understanding?

  • Low level qemu based debugging

    - by Dacav
    I've to test some low level code on an ARM architecture. Typically experimentation is quite complicated on the real board, so I was thinking about QEMU. What I'd like to get is some kind of debugging information like printfs or gdb. I know that this is simple with linux since it implements both the device driver for the QEMU Integrator and the gdb feature, but I'm not working with Linux. Also I suspect that extracting this kind of functionality from the Linux kernel source code would be complicated. I'm searching from some simple operating system that already implements one of those features. Do you have some advice? Thanks in advance.

  • SubSonic-based app that connects to multiple databases

    - by Fervelas
    Hello there, I currently developed an app that connects to SQL Server 2005 database, so my DAL objects where generated using information from that DB. It will also be possible to connect to an Oracle and MySQL db, all with the same table structures (aside from the normal differences in fields, such as varbinary(max) in SQL Server and BLOB in Oracle, and so on). For this purpose, I already defined multiple connection strings and multiple SubSonic providers for the different DB's the app will run on. My question is, if I generated my objects using a SQL Server database, should the generated objects work transparently with the other DB's or do I need to generate a different DAL for each database engine I use? Should I be aware of any possible bugs I may encounter while performing these operations? Thanks in advance for any advice on this issue.
