    - by Andy
    I am writing a tomcat app, and have a need to do authentication within the URL like this: https://user:password@app.wibble.com Except for the life of me i'm not sure how to set it up or able to find the docs to read up on it, clearly my google skills need work. Can anyone tell me where i should be looking for this kind of info or where to start? Cheers Andy

  • Cannot destroy ZFS snapshot: dataset already exists

    - by Morven
    I have a server (T5220, though I doubt it matters) running Solaris 10 8/07 and I have a ZFS pool, "mysql", on internal disk. Within it I have a filesystem "mysql/data/4.1.12", which I snapshot hourly with a script from cron. I have one snapshot, created as one of those hourly snaps, that will not destroy. I have renamed it out of sequence to be "mysql/data/4.1.12@wibble" so that my script will not try and fail to destroy it, but it was originally within the sequence, though I doubt that matters. It renames successfully. The snapshot can be successfully navigated and read from through the .zfs/snapshots directory. It has no clones based on it. Trying to destroy it does this: (265) root@web-mysql4:/# zfs destroy mysql/data/4.1.12@wibble cannot destroy 'mysql/data/4.1.12@wibble': dataset already exists (266) root@web-mysql4:/# which is apparently nonsensical: of course it already exists, that's the point! Anyone seen anything like this before? Web searches show nothing obviously similar. I can provide patches installed if necessary.

  • Add folder name to beginning of filename - getting multiple renames

    - by Flibble Wibble
    I've used dbenham's excellent response to the question of how to add the folder name to the beginning of a filename in a cmd script. @echo off pushd "Folder" for /d %%D in (*) do ( for %%F in ("%%~D\*") do ( for %%P in ("%%F\..") do ( ren "%%F" "%%~nxP_%%~nxF" ) ) ) popd What I'm finding is that seemingly randomly (though it probably isn't) sometimes the script will run through several child folders and rename correctly but then it gets to a folder where it gets stuck in a loop and starts adding the folder name repeatedly to the file inside. I have 90,000 files in 300 folders to rename this weekend. Any chance you can guess the cause? PS: Is there a maximum number of files that are acceptable in each folder?

  • Modify request querystring paramaters to build a new link without resorting to string manipulation

    - by Andrew M
    Hi All, I want to dynamically populate a link with the URI of the current request, but set one specific query string parameter. All other querystring paramaters (if there are any) should be left untouched. And I don't know in advance what they might be. Eg, imagine I want to build a link back to the current page, but with the querystring parameter "valueOfInterest" always set to be "wibble" (I'm doing this from the code-behind of an aspx page, .Net 3.5 in C# FWIW). Eg, a request for either of these two: /somepage.aspx /somepage.aspx?valueOfInterest=sausages would become: /somepage.aspx?valueOfInterest=wibble And most importantly (perhaps) a request for: /somepage.aspx?boring=something /somepage.aspx?boring=something&valueOfInterest=sausages would preserve the boring params to become: /somepage.aspx?boring=something&valueOfInterest=wibble Caveats: I'd like to avoid string manipulation if there's something more elegant in asp.net that is more robust. However if there isn't something more elegant, so be it. I've done (a little) homework: I found a blog post which suggested copying the request into a local HttpRequest object, but that still has a read-only collection for the querystring params. I've also had a look at using a URI object, but that doesn't seem to have a querystring

  • perl: generating permutations from a regular expression

    - by wibble
    I know you can generate all permutations from a list, using glob or Algorithm::Permute for example - but how do you generate all possible permutations from a regular expression? i want to do like: @perms = permute( "/\s[A-Z][0-9][0-9]/" ); sub permute( $regex ) { # code - put all permutations of above regex in a list return @list; }

  • How can I tell NetBeans to use the latest available version of a JAR for a library?

    - by Freiheit
    I have a Netbeans project with a library defined which includes several JARs. These JARs are versioned like lib\blah\com.blah.wibble.jar_0.6.1.201004161543 . These are nightly builds from another project so that version changes often. I know I can point NetBeans at the specific JARs with the version name, but this means that every time I get a new version I have to update the NetBeans library. I can also strip the version name from the JARs, but this makes it hard to track down bugs. "What version of the blah JARs?" is usually the second thing we ask when we find a bug. Is it possible to tell Netbeans to use included com.blah.wibble.jar_[??????] where ???? is some sort of automatic pointer to use the latest available version?

  • Embedding wav files in AS3 Flash/Flex project?

    - by aaaidan
    The Flash IDE is capable of embedding many types of uncompressed sound files, including wav, and offers optional compression when publishing. However, the [Embed] tag, only seems to allow embedding of mp3 files. Is it truly impossible to embed an uncompressed wav file, or am I missing some magic, undocumented mimeType? I was hoping for something like: [Embed source="../../audio/wibble.wav" mimeType="audio/wav"] ...but I get no transcoder registered for mimeType 'audio/wav' It's possible to embed wav or other format as an octet-stream and parse at runtime, but that's pretty heavy handed I think. I'm surprised that even though the Flash IDE can embed uncompressed sound data, [Embed] cannot, given that the swf spec can contain uncompressed sound data. Any takers?

  • xs:choice unbounded list

    - by Matt
    I want to define an XSD schema for an XML document, example below: <?xml version="1.0" encoding="utf-8"?> <view xmlns="http://localhost/model_data" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://localhost/model_data XMLSchemaView.xsd" path="wibble" id="wibble"> <text name="PageTitle">Homepage</text> <text name="Keywords">home foo bar</text> <image name="MainImage"> <description>lolem ipsum</description> <title>i haz it</title> <url>/images/main-image.jpg</url> <type>image/jpeg</type> <alt>alt text for image</alt> <width>400</width> <height>300</height> </image> <link name="TermsAndConditionsLink"> <url>/tnc.html</url> <title>Terms and Conditions</title> <target>_blank</target> </link> </view> There's a view root element and then an unknown number of field elements (of various types). I'm using the following XSD schema: <?xml version="1.0" encoding="utf-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://localhost/model_data" targetNamespace="http://localhost/model_data" id="XMLSchema1"> <xs:element name="text" type="text_field"/> <xs:element name="view" type="model_data"/> <xs:complexType name="model_data"> <xs:choice maxOccurs="unbounded"> <xs:element name="text" type="text_field"/> <xs:element name="image" type="image_field"/> <xs:element name="link" type="link_field"/> </xs:choice> <xs:attribute name="path" type="xs:string"/> <xs:attribute name="id" type="xs:string"/> </xs:complexType> <xs:complexType name="image_field"> <xs:all> <xs:element name="description" type="xs:string"/> <xs:element name="title" type="xs:string"/> <xs:element name="type" type="xs:string"/> <xs:element name="url" type="xs:string"/> <xs:element name="alt" type="xs:string"/> <xs:element name="height" type="xs:int"/> <xs:element name="width" type="xs:int"/> </xs:all> <xs:attribute name="name" type="xs:string"/> </xs:complexType> <xs:complexType name="text_field"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="name" type="xs:string"/> </xs:extension> </xs:simpleContent> </xs:complexType> <xs:complexType name="link_field"> <xs:all> <xs:element name="target" type="xs:string"/> <xs:element name="title" type="xs:string"/> <xs:element name="url" type="xs:string"/> </xs:all> <xs:attribute name="name" type="xs:string"/> </xs:complexType> </xs:schema> This looks like it should work to me, but it doesn't and I always get the following error: Element <text> is not allowed under element <view>. Reason: The following elements are expected at this location (see below) <text> <image> <link> Error location: view / text Details cvc-model-group: Element <text> unexpected by type 'model_data' of element <view>. cvc-elt.5.2.1: The element <view> is not valid with respect to the actual type definition 'model_data'. I've never really used XSD schemas before, so I'd really appreciate it if someone could point out where I'm going wrong.

  • Generic Dictionary and generating a hashcode for multi-part key

    - by Andrew
    I have an object that has a multi-part key and I am struggling to find a suitable way override GetHashCode. An example of what the class looks like is. public class wibble{ public int keypart1 {get; set;} public int keypart2 {get; set;} public int keypart3 {get; set;} public int keypart4 {get; set;} public int keypart5 {get; set;} public int keypart6 {get; set;} public int keypart7 {get; set;} public single value {get; set;} } Note in just about every instance of the class no more than 2 or 3 of the keyparts would have a value greater than 0. Any ideas on how best to generate a unique hashcode in this situation? I have also been playing around with creating a key that is not unique, but spreads the objects evenly between the dictionaries buckets and then storing objects with matched hashes in a List< or LinkedList< or SortedList<. Any thoughts on this?

  • Returning pointers in a thread-safe way.

    - by Roddy
    Assume I have a thread-safe collection of Things (call it a ThingList), and I want to add the following function. Thing * ThingList::findByName(string name) { return &item[name]; // or something similar.. } But by doing this, I've delegated the responsibility for thread safety to the calling code, which would have to do something like this: try { list.lock(); // NEEDED FOR THREAD SAFETY Thing *foo = list.findByName("wibble"); foo->Bar = 123; list.unlock(); } catch (...) { list.unlock(); throw; } Obviously a RAII lock/unlock object would simplify/remove the try/catch/unlocks, but it's still easy for the caller to forget. There are a few alternatives I've looked at: Return Thing by value, instead of a pointer - fine unless you need to modify the Thing Add function ThingList::setItemBar(string name, int value) - fine, but these tend to proliferate Return a pointerlike object which locks the list on creation and unlocks it again on destruction. Not sure if this is good/bad practice... What's the right approach to dealing with this?

  • Agile web development with rails

    - by Steve
    Hi.. This code is from the agile web development with rails book.. I don't understand this part of the code... User is a model which has name,hashed_password,salt as its fields. But in the code they are mentioning about password and password confirmation, while there are no such fields in the model. Model has only hashed_password. I am sure mistake is with me. Please clear this for me :) User Model has name,hashed_password,salt. All the fields are strings require 'digest/sha1' class User < ActiveRecord::Base validates_presence_of :name validates_uniqueness_of :name attr_accessor :password_confirmation validates_confirmation_of :password validate :password_non_blank def self.authenticate(name, password) user = self.find_by_name(name) if user expected_password = encrypted_password(password, user.salt) if user.hashed_password != expected_password user = nil end end user end def password @password end def password=(pwd) @password = pwd return if pwd.blank? create_new_salt self.hashed_password = User.encrypted_password(self.password, self.salt) end private def password_non_blank errors.add(:password,"Missing password")if hashed_password.blank? end def create_new_salt self.salt = self.object_id.to_s + rand.to_s end def self.encrypted_password(password, salt) string_to_hash = password + "wibble" + salt Digest::SHA1.hexdigest(string_to_hash) end end

  • How to process a large post array in PHP where item names are all different and not known in advance

    - by Salnajjar
    I have a PHP page that queries a DB to populate a form for the user to modify the data and submit. The query returns a number of rows which contain 3 items: ImageID ImageName ImageDescription The PHP page titles each box in the form with a generic name and appends the ImageID to it. Ie: ImageID_03 ImageName_34 ImageDescription_22 As it's unknown which images are going to have been retrieved from the DB then I can't know in advance what the name of the form entries will be. The form deals with a large number of entries at the same time. My backend PHP form processor that gets the data just sees it as one big array: [imageid_2] => 2 [imagename_2] => _MG_0214 [imageid_10] => 10 [imagename_10] => _MG_0419 [imageid_39] => 39 [imagename_39] => _MG_0420 [imageid_22] => 22 [imagename_22] => Curly Fern [imagedescription_2] => Wibble [imagedescription_10] => Wobble [imagedescription_39] => Fred [imagedescription_22] => Sally I've tried to do an array walk on it to split it into 3 arrays which set places but am stuck: // define empty arrays $imageidarray = array(); $imagenamearray = array(); $imagedescriptionarray = array(); // our function to call when we walk through the posted items array function assignvars($entry, $key) { if (preg_match("/imageid/i", $key)) { array_push($imageidarray, $entry); } elseif (preg_match("/imagename/i", $key)) { // echo " ImageName: $entry"; } elseif (preg_match("/imagedescription/i", $key)) { // echo " ImageDescription: $entry"; } } array_walk($_POST, 'assignvars'); This fails with the error: array_push(): First argument should be an array in... Am I approaching this wrong?
