• Locking NFS files in PHP

  - by Oli

  Part of my latest webapp needs to write to file a fair amount as part of its logging. One problem I've noticed is that if there are a few concurrent users, the writes can overwrite each other (instead of appending to file). I assume this is because of the destination file can be open in a number of places at the same time. flock(...) is usually superb but it doesn't appear to work on NFS... Which is a huge problem for me as the production server uses a NFS array. The closest thing I've seen to an actual solution involves trying to create a lock dir and waiting until it can be created. To say this lacks elegance is understatement of the year, possibly decade. Any better ideas? Edit: I should add that I don't have root on the server and doing the storage in another way isn't really feasible any time soon, not least within my deadline.

• Using recursion an append in prolog

  - by Adrian

  Lets say that I would like to construct a list (L2) by appending elements of another list (L) one by one. The result should be exactly the same as the input. This task is silly, but it'll help me understand how to recurse through a list and remove certain elements. I have put together the following code: create(L, L2) :- (\+ (L == []) -> L=[H|T], append([H], create(T, L2), L2);[]). calling it by create([1,2,3,4], L2) returns L2 = [1|create([2,3,4], **)\. which is not a desired result.

• HTTP Content-type header for cached files

  - by Brian

  Hello, Using Apache with mod_rewrite, when I load a .css or .js file and view the HTTP headers, the Content-type is only set correctly the first time I load it - subsequent refreshes are missing Content-type altogether and it's creating some problems for me. I can get around this by appending a random query string value to the end of each filename, eg. http://www.site.com/script.js?12345 However, I don't want to have to do that, since caching is good and all I want is for the Content-type to be present. I've tried using a RewriteRule to force the type but still didn't solve the problem. Any ideas? Thanks, Brian

• wx Menu disappears from frame when shown as a popup

  - by Adam Fraser

  I'm trying to create a wx.Menu that will be shared between a popup (called on right-click), and a sub menu accessible from the frame menubar. The following code demonstrates the problem. If you open the "MENUsubmenu" from the menubar the item "asdf" is visible. If you right click on the frame content area, "asdf" will be visible from there as well... however, returning to the menubar, you will find that "MENUsubmenu" is vacant. Why is this happening and how can I fix it? import wx app = wx.PySimpleApp() m = wx.Menu() m.Append(-1, 'asdf') def show_popup(evt): ''' R-click callback ''' f.PopupMenu(m, (evt.X, evt.Y)) f = wx.Frame(None) f.SetMenuBar(wx.MenuBar()) frame_menu = wx.Menu() f.MenuBar.Append(frame_menu, 'MENU') frame_menu.AppendMenu(-1,'submenu', m) f.Show() f.Bind(wx.EVT_RIGHT_DOWN, show_popup) app.MainLoop() Interestingly, appending the menu to MenuBar works, but is not the behavior I want: import wx app = wx.PySimpleApp() m = wx.Menu() m.Append(-1, 'asdf') def show_popup(evt): f.PopupMenu(m, (evt.X, evt.Y)) f = wx.Frame(None) f.SetMenuBar(wx.MenuBar()) f.MenuBar.Append(m, 'MENU') f.Show() f.Bind(wx.EVT_RIGHT_DOWN, show_popup) app.MainLoop()

• Return Count from Netflix oData Service When the LINQ Count() Method Doesn't Work

  - by Craig Shoemaker

  Is there a way to use a LINQ expression to request a Count query from the Netflix oData service? The Netflix documentation shows that you can return counts by appending $count to a request for a collection, but a URL like this: http://netflix.cloudapp.net/Catalog/Genres/$count Is not generated from an expression like this: var count = (from g in catalog.Genres select g).Count(); The above code returns an error saying that the Count method is not supported. Is there a way to do this in LINQ, or do I just need to make WebClient request to get the value?

• Javascript callback on blackberry

  - by Jeff

  I'm working on a mobile project, and I have a script that is dynamically generated on the backend and then appended to the document (the html page). Desktop browsers seem to append the script correctly and call any functions in the script, however, I can't get this to happen on Blackberry phones. I know that the script is being appending because I can alert it after I append it. I just can get it to call the function in the script. For example, if I have code like this: var scriptText = document.createElement('script'); scriptText.type = 'text/javascript'; scriptText.id = 'thisScript'; scriptText.innerHTML = 'alert("hello");'; document.getElementById('idName').appendChild(scriptText); alert(document.getElementById('thisScript')); //Alerts the script element. This will alert 'hello' in desktop browsers and even the iPhone/iPodTouch, but not BlackBerry's. Anyone have any idea why? Or if there's a fix/hack?

  - by Sarath R Nair

  My question may appear silly. But as I am a rookie in Python , help me out. I have to pass a line to a stopword removal function. It works fine.

• ASP MVC 2 : Custom display of a required form element based on ModelMetaData

  - by Nigel

  I have an MVC 2 application that utilises forms. The required fields within the form are set using attributes that update the model metadata. The form fields are created using the MVC HtmlHelper method : Html.EditorFor. This works fine so far as validation is concerned, but it seems that by default the required fields are not displayed to the user (for example by appending a * to the control). If I wanted to provide some custom means of displaying this fact to the user (lets immagine I want to change the background colour of the edit control for example), where is the best place to do it. Would I need to create a custom html helper to replace EditorFor? I tried but it seemed difficult to gain access to the metadata for the correct property. I already have a custom ModelMetaDataProvider so there is no problem adding it there if that is the correct place.

• filter search results with another form

  - by Ygam

  so here's the problem I have one form, it outputs search results after submit, with this URL http://localhost/thi/search/results?keyword=barma&search=1&minprice=nomin&maxprice=nomax&minroom=nomin&maxroom=nomax&minyear=nomin&maxyear=2010 Now I have another form, which is supposed to filter the results from the previous form by getting the current url of the search results and appending to it the GET variables submitted by this form. I tried filtering before, but that is with anchor links. How am I supposed to do it with forms? Anny approaches?

• Rails Unit Testing with MyISAM Tables

  - by tadman

  I've got an application that requires the use of MyISAM on a few tables, but the rest are the traditional InnoDB type. The application itself is not concerned with transactions where it applies to these records, but performance is a concern. The Rails testing environment assumes the engine used is transactional, though, so when the test database is generated from the schema.rb it is imported with the same engine. Is it possible to over-ride this behaviour in a simple manner? I've resorted to an awful hack to ensure the tables are the correct type by appending this to test_helper.rb: (ActiveRecord::Base.connection.select_values("SHOW TABLES") - %w[ schema_info ]).each do |table_name| ActiveRecord::Base.connection.execute("ALTER TABLE `#{table_name}` ENGINE=InnoDB") end Is there a better way to make a MyISAM-backed model be testable?

• make changes to html before append with jquery

  - by Pradyut Bhattacharya

  I m calling a page using ajax and making changes to it using jquery but the changes are not reflected after appending(append) it to a div as the changes are done to the html but the html var remains the same. how do i make the changes to the html var and then append to the DOM if i use the code directly to the DOM then there will be changes in the previous elements in the DOM the code $.ajax({ type: "POST", url: 'more_images.jsp', data: ({uid:uid, aid:aid, imgid:imgid}) , cache: false, success: function(html) { html = $.trim(html); $(html).filter('.corner-all').corner('5px'); $(html).filter('ol.c_album > li .img_c').corner('3px'); $(html).filter("ol.c_album > li ").find('a').attr('target', '_blank'); $('#images_list').append(html); } }); thanks Pradyut

• How should I handle incomplete packet buffers?

  - by Benjamin Manns

  I am writing a client for a server that typically sends data as strings in 500 or less bytes. However, the data will occasionally exceed that, and a single set of data could contain 200,000 bytes, for all the client knows (on initialization or significant events). However, I would like to not have to have each client running with a 50 MB socket buffer (if it's even possible). Each set of data is delimited by a null \0 character. What kind of structure should I look at for storing partially sent data sets? For example, the server may send ABCDEFGHIJKLMNOPQRSTUV\0WXYZ\0123!\0. I would want to process ABCDEFGHIJKLMNOPQRSTUV, WXYZ, and 123! independently. Also, the server could send ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890LOL123HAHATHISISREALLYLONG without the terminating character. I would want that data set stored somewhere for later appending and processing. Also, I'm using asynchronous socket methods (BeginSend, EndSend, BeginReceive, EndReceive) if that matters.

• Updating Excel Cell with Non-Numeric Data in C#

  - by kbo206

  I have a query that is ExcelQuery = "Update [Sheet1$] set CITIZEN_ID = #" + value + " where CITIZEN_ID = " + value; As you can see, I'm essentially just appending a "#" onto the CITIZEN_ID field. value is a int/numeric value. So if I had "256" in the CITIZEN_ID column it would be converted to "#256" When I execute this I get an OleDbException Syntax error in date in query expression so I surrounded part of the query in single quotes like this, ExcelQuery = "Update [Sheet1$] set CITIZEN_ID = '#" + value + "' where CITIZEN_ID = " + value; With that I get yet another OleDbException this time with, Data type mismatch in criteria expression. I'm guessing for some reason the CITIZEN_ID fields don't want to take anything besides a plain number. Is there any way I can remedy this to get that pound symbol in? Thanks!

• Forumotion profile customization using jQuery based on URL

  - by Harvengure

  The idea is have a jQuery snippet (I like Jquery...I can understand it better then regular javascript) that will detect that when it has been run on a profile with a url such as "http://customize.forum-motion.com/profile.forum?mode=viewprofile&u=1" (just as an example)...then upon detecting that it is a url of a profile...fetch data from a specific (and most likely hidden) element before wrapping that data in css tags and appending it to the heady of the current document. In short I'm trying to figure out how to make a sort of profile customization system where users can create their own css. The biggest problem I am having so far is figuring out how to make it so that the snippet can figure out what URL its being run on. Is there a function that can do this in jQuery at all?

• How can I fix the scroll bug when using Windows rich edit controls in wxpython?

  - by ChrisD

  When using wx.TextCtl with the wx.TE_RICH2 option in windows, I get this strange bug with the auto-scroll when using the AppendText function. It scrolls so that all the text is above the visible area, which isn't very useful behaviour. I tried just adding a call to ScrollLines(-1) after appending the text - which does scroll it to the correct position - but this can lead to the window flashing when it auto-scrolls. So I'm looking for another way to automatically scroll to the bottom. So far, my solution is to bypass the AppendText functions auto-scroll and implement my own, like this: def append_text(textctrl, text): before_number_of_lines = textctrl.GetNumberOfLines() textctrl.SetInsertionPointEnd() textctrl.WriteText(text) after_number_of_lines = textctrl.GetNumberOfLines() textctrl.ScrollLines(before_number_of_lines - after_number_of_lines + 1) Is there a better way?

• Effective methods for reading and writing large files in C

  - by Bertholt Stutley Johnson

  I'm writing an application that deals with very large user-generated input files. The program will copy about 95 percent of the file, effectively duplicating it and switching a few words and values in the copy, and then appending the copy (in chunks) to the original file, such that each block (consisting of between 10 and 50 lines) in the original is followed by the copied and modified block, and then the next original block, and so on. The user-generated input conforms to a certain format, and it is highly unlikely that any line in the original file is longer than 100 characters long. Which would be the better approach? a) To use one file pointer and use variables that hold the current position of how much has been read and where to write to, seeking the file pointer back and forth to read and write; or b) To use multiple file pointers, one for reading and one for writing. I am mostly concerned with the efficiency of the program, as the input files will reach up to 25,000 lines, each about 50 characters long. Thanks!

• Add entry to list and remove first one in Python

  I have a list of about 40 entries. And I frequently want to append an item to the start of the list (with id 0) and want to delete the last entry (with id 40) of the list. how do i do this the best? like: (example with 5 entries) [0] = "herp" [1] = "derp" [2] = "blah" [3] = "what" [4] = "da..." after adding "wuggah" and deleting last it should be like: [0] = "wuggah" [1] = "herp" [2] = "derp" [3] = "blah" [4] = "what" or appending one and deleting first. And I don't want to end up manually moving them one after another all of the entries to the next id.

  Hi, i'm deploying a ror application and now i have to rewrite the url (in apache) to add a prefix www to the url add / to the end of the url So i took the following approach: RewriteCond %{REQUEST_URI} ^/[^\.]+[^/]$ RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1/ [R=301,L] RewriteCond %{HTTP_HOST} ^foo\.com RewriteRule ^(.*)$ http://www.foo.com/$1 [R=301,L] The problem is that it is appending two trailing slash to my url So for example a resource /question/ask are becoming: http://foo.com//question/ask I tried to add the following Rule before all my Rewrite rules to try to remove the double //: RewriteCond %{REQUEST_URI} ^// RewriteRule ([^/]*)/+(.*) http://www.foo.com/$1/$2 [R=301,L] but it didnt work.. any idea to rip off all extras "//" added to the url?

• php mysql flex unicode

  - by JonoB

  I have a problem with saving the £ symbol to a mysql database. I am running a flex front end, with a php + mysql backend When I save a record from flex, the string gets sent to the server as "This amount is £10" php views the string as above, and when it gets saved into the DB, it gets saved as "This amount is £10". My understanding is that this is correct based on MySQL or PHP is appending a  whenever the £ is used I now retrieve the above record, and it gets sent to flex as "This amount is £10". Flex correctly displays this in a textarea as "This amount is £10" I change another field in the same record in flex, and re-save the transaction. The string now gets sent to the server as "This amount is £10" The record is now saved into the DB as "The amount is £10". Each time the record is re-saved, this effect snowballs. Thanks for any advice you can give.
