• Global.asax parser errors when deploying MVC 1 application to remote server.

  - by mannish

  So we're having some issues deploying an ASP.NET MVC app to a client site. Basically when we try to test the app from localhost, we get the dreaded Global.asax parser error indicating it could not load the application global. Research indicates there are basically 4 possible reasons for this exception we're seeing: The solution hasn't been built. This clearly isn't the case since we can deploy it here and it runs fine on any machine we deploy to AND we had to build and publish the darn thing to deploy it anyway. The Global.asax namespace inheritance does not match the application global code file. Again we double checked this and since it runs just fine here that can't be the issue. Miscellaneous non-descript IIS/VS.NET mischief. Basically something get's wonky in IIS or VS.NET and the web server won't behave correctly for this application. We've done cleans and rebuilds, we've deleted virtual dir and recreated, and performed all of the IIS munging that we've found elsewhere online. Various combinations of IIS bounces, server reboots, virtual dir/application recreation, etc. Code level permissions issue. We've verified full trust in machine/web config in the framework directory, we've set .NET trust to full in IIS, we've granted Everyone full control on the directories just to hit it with the security hammer, etc. etc. The pertinent detials: Windows Server 2008 x64 IIS 7, 32 bit compatible app pool (app was written on 32 bit OS compiled for any cpu) App pool identity set to NetworkService Microsoft ASP.NET MVC 1.0 XCopy deployment We deployed another read-only app just fine. The significant difference in this app is the use of NHibernate and Log4Net which require full trust. Additionally, the actual project name of the web project differs from the default namespace however the Inherits namespace in Global.asax and the Global.asax.cs files match so this shouldn't be an issue. Anybody have any bright ideas? We're officially down to just the dim ones.

• Cruise Control.net Ms Build Task setting XML output Name

  - by Eric Brown - Cal

  We are running version 1.5.6755.1 of CruiseControl.net. Here is our block that executes a build <!-- MSBuild of Source Code --> <cb:define name="BuildOneProject-block"> <msbuild> <executable>C:\WINDOWS\Microsoft.NET\Framework\v3.5\MSBuild.exe</executable> <!-- Directory where source is --> <workingDirectory>D:\CC\$(AppName)\Source</workingDirectory> <!-- Solution file to be built--> <projectFile>D:\CC\$(AppName)\Source\$(ProjectName)\$(ProjectName).csproj</projectFile> <buildArgs>/noconsolelogger /p:SolutionName=\$(AppName) /p:SolutionDir=D:\CC\$(AppName)\Source /p:Configuration=$(ReleaseOrDebug) /v:diag</buildArgs> <targets>Build</targets> <timeout>900</timeout> <logger>C:\Program Files\CruiseControl.NET\server\ThoughtWorks.CruiseControl.MsBuild.dll</logger> </msbuild> </cb:define> When this run it generates a file with a name like.. msbuild-results-5cb1c8fa-1bba-4e97-a0b1-b2bf637308dc.xml Is there another tag on the MsBuild task that allows me to name the xml file? Is there an argument to the Logger that allows me to specify the name of the xml file?

• Are Fortran control characters (carriage control) still implemented in compilers?

  - by CmdrGuard

  In the book Fortran 95/2003 for Scientists and Engineers, there is much talk given to the importance of recognizing that the first column in a format statement is reserved for control characters. I've also seen control characters referred to as carriage control on the internet. To avoid confusion, by control characters, I refer to the characters "1, a blank (i.e. \s), 0, and +" as having an effect on the vertical spacing of output when placed in the first column (character) of a FORMAT statement. Also, see this text-only web page written entirely in fixed-width typeface : Fortran carriage-control (because nothing screams accuracy and antiquity better than prose in monospaced font). I found this page and others like it to be not quite clear. According to Fortran 95/2003 for Scientists and Engineers, failure to recall that the first column is reserved for carriage control can lead to horrible unintended output. Paraphrasing Dave Barry, type the wrong character, and nuclear missiles get fired at Norway. However, when I attempt to adhere to this stern warning, I find that gfortran has no idea what I'm talking about. Allow me to illustrate my point with some example code. I am trying to print out the number Pi: PROGRAM test_format IMPLICIT NONE REAL :: PI = 2 * ACOS(0.0) WRITE (*, 100) PI WRITE (*, 200) PI WRITE (*, 300) PI 100 FORMAT ('1', "New page: ", F11.9) 200 FORMAT (' ', "Single Space: ", F11.9) 300 FORMAT ('0', "Double Space: ", F11.9) END PROGRAM test_format This is the output: 1New page: 3.141592741 Single Space: 3.141592741 0Double Space: 3.141592741 The "1" and "0" are not typos. It appears that gfortran is completely ignoring the control character column. My question, then, is this: Are control characters still implemented in standards compliant compilers or is gfortran simply not standards compliant? For clarity, here is the output of my gfortran -v Using built-in specs. Target: powerpc-apple-darwin9 Configured with: ../gcc-4.4.0/configure --prefix=/sw --prefix=/sw/lib/gcc4.4 --mandir=/sw/share/man --infodir=/sw/share/info --enable-languages=c,c++,fortran,objc,java --with-gmp=/sw --with-libiconv-prefix=/sw --with-ppl=/sw --with-cloog=/sw --with-system-zlib --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib --disable-libjava-multilib --build=powerpc-apple-darwin9 --host=powerpc-apple-darwin9 --target=powerpc-apple-darwin9 Thread model: posix gcc version 4.4.0 (GCC)

• Asp.Net Login Control very slow initial connection to Non-Trusted AD Domain

  - by Eric Brown - Cal

  ASP.NET Login control is very slow making the initial connection to AD when authenticating to a different domain than the domain the web server is a member of. Problem occurs for the IIS server and when using with the Visual Studio's built in web server. It takes about 30 seconds the first time when attempting to use the control to connect against another domain. There is no trust relationship bewteen the web server's domain and the other domains (attempted connecting to several different domains). Subsequent connections execute quickly until the connection times out. Using Systernals Process Monitor to troubleshoot, there are two OpenQuery operations right before the delay to "C:\WINDOWS\asembly\GAC_MSIL\System.DirectoryServices\2.0.0.0_b03f5f7f11d50a3a\Netapi32.dll with a result NAME NOT FOUND" and right after the 30 second delay the TCP Send and TCP Recieves indicate communication begins with the AD server. Things we have tried: Impersonating an administrator on the web server in the web.config; Granting permissions to the CryptoKeys to the NetworkService and ASPNET; Specifying by IP instead of DNS name; Multiple variations of specifying the name and ldap server with domains and OU's; Local host entries; Looked for ports being blocked (SYN_SENT) with netstat -an. Nslookup resolves all the domains and systems involved correectly. TraceRt shows the Correct routes Any Idea or hints are greately appreicated.

• Visual Studio 2010 / ASP.NET MVC / Publish

  - by SevenCentral

  I just did a clean install on Windows 7 x64 Professional with the final release of Visual Studio 2010 Premium. In order to duplicate what I'm experiencing do the following in: Create a new ASP.NET MVC 2 Web Application Right click the project and select Properties On the Web tab, select "Use Local IIS Web Server" Click on Create Virtual Directory Save all Unload the project Edit the project file Change MvcBuildViews to true Save all Reload project Right click the project and select Publish Choose the file system publish method Enter a target location Choose Delete all existing files Select Publish Right click the project Select Publish Each time I do the above I get the following errror: "It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level..." The error originates from obj\debug\package\packagetmp\web.config, relative to the project directory. I can repeat this all day long with any MVC 2 project I've built. In order to fix this problem, I need to set MvcBuildViews to false in the project file. That's not really an option. This wasn't a problem in Visual Studio 2008 and it seems to be an issue with the way the Publish command stages files beneath the project directory. Can anyone else duplicate this error? Is this a bug or by design? Is there a fix, workaround, etc...? Thanks.

• PHP script not automatically updating when moved to another server

  - by user32007

  A friend built a ranking system on his site and I am trying to host in on mine via WordPress and Go Daddy. It updates for him but when I load it to my site, it works for 6 hours, but as soon as the reload is supposed to occur, it errors and I get a 500 timeout error. His page is at: jeremynoeljohnson .com/yakezieclub My page is currently at http://sweatingthebigstuff.com/yakezieclub but when you ?reload=1 it will give the error. Any idea why this might be happening? Any settings that I might need to change? Here is the top of the index.php file. I'm not sure which part of any of it is messing up. I literally uploaded the same code as him. Here's the reload part: $cachefile = "rankings.html"; $daycachefile = "rankings_history.xml"; $cachetime = (60 * 60) * 6; // every 6 hours, the cache refreshes $daycachetime = (60 * 60) * 24; // every 24 hours, the history will be written to // - or whenever the page is requested after 24 hours has passed $writenewdata = false; if (!empty($_GET['reload'])) { if ($_GET['reload']== 1) { $cachetime = 1; } } if (!empty($_GET['reloadhistory'])) { if ($_GET['reloadhistory'] == 1) { $daycachetime = 1; $cachetime = 1; } } if (file_exists($daycachefile) && (time() - $daycachetime < filemtime($daycachefile))) { // Do nothing } else { $writenewdata = true; $cachetime = 1; } // Serve from the cache if it is younger than $cachetime if (file_exists($cachefile) && (time() - $cachetime < filemtime($cachefile))) { include($cachefile); echo "<!-- Cached ".date('jS F Y H:i', filemtime($cachefile))." -->"; exit; } ob_start(); // start the output buffer ?>

• VS 2008 created shortcut doesn't show up in "Send To" menu

  - by Brettski

  I have a WinForms application built using Visual Studio 2008. I added a Setup Project to the solution to create an installation MSI file. I need the setup project to create a shortcut pointing to the application's executable in the users Send To Menu. This way when someone right clicks on a file, my application will show in the Send To list and be selected. I figured out under the file system settings of the Setup project how to add a shortcut to the Users Send To Menu. The problem is, the shortcut doesn't show in the Send To menu when you right click on a file. If I manually create a shortcut to my executable the application does show in the Send To menu. I have read many suggestions on the web to required registry entries for this to work. There is a VBS file written by Ramesh Srinivasan which inserts them. On every system I have tried this on the registry values already existed, so this is not the problem. It seems more to be with the shortcut Visual Studio (or the msi anyway) is creating.

• L10N: Trusted test data for Locale Specific Sorting

  - by Chris Betti

  I'm working on an internationalized database application that supports multiple locales in a single instance. When international users sort data in the applications built on top of the database, the database theoretically sorts the data using a collation appropriate to the locale associated with the data the user is viewing. I'm trying to find sorted lists of words that meet two criteria: the sorted order follows the collation rules for the locale the words listed will allow me to exercise most / all of the specific collation rules for the locale I'm having trouble finding such trusted test data. Are such sort-testing datasets currently available, and if so, what / where are they? "words.en.txt" is an example text file containing American English text: Andrew Brian Chris Zachary I am planning on loading the list of words into my database in randomized order, and checking to see if sorting the list conforms to the original input. Because I am not fluent in any language other than English, I do not know how to create sample datasets like the following sample one in French (call it "words.fr.txt"): cote côte coté côté The French prefer diacritical marks to be ordered right to left. If you sorted that using code-point order, it likely comes out like this (which is an incorrect collation): cote coté côte côté Thank you for the help, Chris

• Record Disappeared from Mysql Table, How Can I Find Out What Happened?

  - by Jascha

  I got the fire alarm phone call, AIM messages and email today from a client stating "The site is down!, WTF happened?!" Well, after a little digging, it turns out one of the records in a table had been wiped clean, but without removing the row itself. So, I had the representation of data, but a bunch of empty fields. (needless to day I need to write into my code a catch for this.) What my real question is, where can I figure out what happened? I've got access to phpmyadmin and that's about it. I found some access logs on in the root directory of my server, but that just tells me the client was in the admin area I built editing that record, I'd like to know specifically what they did that made all of the data go away. (what query was run etc...) is it possible without real server admin access? is there a neat little php to mysql class that returns data like this? Thanks in advance. -Jascha

• How can get dtrace to run the traced command with non-root priviledges ?

  - by Gyom

  OS X lacks linux's strace, but it has dtrace which is supposed to be so much better. However, I miss the ability to do simple tracing on individual commands. For example, on linux I can write strace -f gcc hello.c to caputre all system calls, which gives me the list of all the filenames needed by the compiler to compile my program (the excellent memoize script is built upon this trick) I want to port memoize on the mac, so I need some kind of strace. What I actually need is the list of files gcc reads and writes into, so what I need is more of a truss. Sure enough can I say dtruss -f gcc hello.c and get somewhat the same functionality, but then the compiler is run with root priviledges, which is obviously undesirable (apart from the massive security risk, one issue is that the a.out file is now owned by root :-) I then tried dtruss -f sudo -u myusername gcc hello.c, but this feels a bit wrong, and does not work anyway (I get no a.out file at all this time, not sure why) All that long story tries to motivate my original question: how do I get dtrace to run my command with normal user priviledges, just like strace does in linux ? Edit: is seems that I'm not the only one wondering how to do this: question #1204256 is pretty much the same as mine (and has the same suboptimal sudo answer :-)

• How do I assert that two arbitrary type objects are equivalent, without requiring them to be equal?

  - by Tomas Lycken

  To accomplish this (but failing to do so) I'm reflecting over properties of an expected and actual object and making sure their values are equal. This works as expected as long as their properties are single objects, i.e. not lists, arrays, IEnumerable... If the property is a list of some sort, the test fails (on the Assert.AreEqual(...) inside the for loop). public void WithCorrectModel<TModelType>(TModelType expected, string error = "") where TModelType : class { var actual = _result.ViewData.Model as TModelType; Assert.IsNotNull(actual, error); Assert.IsInstanceOfType(actual, typeof(TModelType), error); foreach (var prop in typeof(TModelType).GetProperties()) { Assert.AreEqual(prop.GetValue(expected, null), prop.GetValue(actual, null), error); } } If dealing with a list property, I would get the expected results if I instead used CollectionAssert.AreEquivalent(...) but that requires me to cast to ICollection, which in turn requries me to know the type listed, which I don't (want to). It also requires me to know which properties are list types, which I don't know how to. So, how should I assert that two objects of an arbitrary type are equivalent? Note: I specifically don't want to require them to be equal, since one comes from my tested object and one is built in my test class to have something to compare with.

• Display subclass data in XCode Expression window

  - by Nick VanderPyle

  I'm debugging an iPhone application I've written using XCode 3.2 and I cannot view the relevant public properties of an object I pull from Core Data. When I watch the object in the Expressions window it only displays the data from the base NSManagedObject. I'd like to see the properties that are on the subclass, not the superclass. If it helps, here's some of the code I'm using. Settings is a subclass of NSManagedObject. I created it using XCode's built-in modeler. Declared like: @interface Settings : NSManagedObject { } @property (nonatomic, retain) NSNumber * hasNews; @property (nonatomic, retain) NSString * logoUrl; @property (nonatomic, retain) NSNumber * hasPaymentGateway; @property (nonatomic, retain) NSString * customerCode; ... In the interface of my controller I have: Settings *settings; I populate settings with: settings = (Settings *)[NSEntityDescription insertNewObjectForEntityForName:@"Settings" inManagedObjectContext:UIAppManagedObjectContext()]; I then set the properties like: settings.hasNews = [NSNumber numberWithBool:TRUE]; I've tried casting settings as (Settings *) in the Expression window but that doesn't help. All I see are the properties to NSManagedObject. I'm using NSLog but would rather not.

• Getting a key in the ActionScript Dictionary

  - by Rudy

  Hello, I am using a Dictionary in ActionScript as a queue, sort of, still reading most of the time as an associative container, but I need one time to make a loop to run through the whole dictionary, such as for (var key:String in queue) . Inside this for loop I perform some actions on an element and then call delete on that key. My issue is that I would like to wait for an Event before fetching the next element in this queue. Basically my for loop runs too fast. I would like to fetch the next key all the time, but I know there is no built in method. A solution I thought is to add a break to the loop, as the for.. in will automatically fetch the next key, but it would be a loop which always executes one time, simply to fetch the next key. This sounds a bit counter intuitive. I hope my problem makes sense and I really look for some better ideas than what I currently have. Thanks for your help! Rudy

• MS Access 2003 - Is there a way to programmatically define the data for a chart?

  - by Justin

  So I have some VBA for taking charts built with the Form's Chart Wizard, and automatically inserting it into PowerPoint Presentation slides. I use those chart-forms as sub forms within a larger forms that has parameters the user can select to determine what is on the chart. The idea is that the user can determine the parameter, build the chart to his/her liking, and click a button and have it in a ppt slide with the company's background template, blah blah blah..... So it works, though it is very bulky in terms of the amount of objects I have to use to accomplish this. I use expressions such as the following: like forms!frmMain.Month&* to get the input values into the saved queries, which was fine when i first started, but it went over so well and they want so many options, that it is driving the number of saved queries/objects up. I need several saved forms with charts because of the number of different types of charts I need to have this be able to handle. SO FINALLY TO MY QUESTION: I would much rather do all this on the fly with some VBA. I know how to insert list boxes, and text boxes on a form, and I know how to use SQL in VBA to get the values I want from tables/queries using VBA, I just don't know if there is some vba I can use to set the data values of the charts from a resulting recordset: DIM rs AS DAO.Rescordset DIM db AS DAO.Database DIM sql AS String sql = "SELECT TOP 5 Count(tblMain.TransactionID) AS Total, tblMain.Location FROM tblMain WHERE (((tblMain.Month) = """ & me.txtMonth & """ )) ORDER BY Count (tblMain.TransactionID) DESC;" set db = currentDB set rs = db.OpenRecordSet(sql) rs.movefirst some kind of cool code in here to make this recordset the data of chart in frmChart ("Chart01") thanks for your help. apologies for the length of the explanation.

• 'Stack level too deep' error in engine-like plugin with globalize

  - by nutsmuggler

  Hello folks. I have built an engine-like plugin thanks to the new features of Rails 2.3. It's a 'Product' module for a CMS, extrapolated from a previously existing (and working) model/controller. The plugin relies on easy_fckeditor and on globalize (description and title field are localised), and I suspect that globalized could be the culprit here... Everything works fine, except for the update action. I get the following error message: (posting just the first lines, all the message is about attribute_methods) stack level too deep /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/attribute_methods.rb:64:in `generated_methods?' /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/attribute_methods.rb:241:in `method_missing' /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/attribute_methods.rb:249:in `method_missing' For referenze, the full error stack is here: http://pastie.org/596546 I've tried to debug eliminating all the input fields, one by one, but I keep getting the error. fckeditor doesn't seem the culprit (error even without fckeditor) This is the action: def update params[:product][:term_ids] ||= [] @product = Product.find(params[:id]) respond_to do |format| if @product.update_attributes(params[:product]) flash[:notice] = t(:Product_was_successfully_updated) format.html { redirect_to products_path } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @product.errors, :status => :unprocessable_entity } end end end As you see it's quite straightforward. Of course I am not hoping someone to solve this question straightaway, I'd just like to have a head up, a suggestion about where to look to solve this issue. Thanks in advance, Davide

• Eclipse won't believe I have Maven 2.2.1

  - by Andrew Clegg

  I have a project (built from an AppFuse template) that requires Maven 2.2.1. So I upgraded to this (from 2.1.0) and set my path and my M2_HOME and MAVEN_HOME env variables. Then I ran mvn eclipse:eclipse and imported the project into Eclipse (Galileo). However, in the problems list for the project (and at the top of the pom.xml GUI editor) it says: Unable to build project '/export/people/clegg/data/GanymedeWorkspace/funcserve/pom.xml; it requires Maven version 2.2.1 (Please ignore 'GanymedeWorkspace', I really am using Galileo!) This persists whether I set Eclipse to use its Embedded Maven implementation, or the external 2.2.1 installation, in the Preferences - Maven - Installations dialog. I've tried closing and reopening the project, reindexing the repository, cleaning the project, restarting the IDE, logging out and back in again, everything I can think of! But Eclipse still won't believe I have Maven 2.2.1. I just did a plugin update so I have the latest version of Maven Integration for Eclipse -- 0.9.8.200905041414. Does anyone know how to convince Eclipse I really do have the right version of Maven? It's like it's recorded the previous version somewhere else and won't pay any attention to my changes :-( Many thanks! Andrew.

• Creating a draft version of the page before publishing in Drupal 6?

  - by Marco

  I've been looking for a good way to handle revisions in Drupal, but I am yet to succeed. For some reason there is no built in way to save a draft (that I've found so far), and the modules I've tried so far do not seem to fully work. First I tried save_as_draft, which seemed to do almost what I wanted, and if I'm not mistaken, also handles CCK fields. Sadly it seems to be broken somehow, so I can't edit a page once I've saved it as a draft.. maybe I could fix it by going through the code, but that would not be my preferred solution. The other module I tried is aptly named draft, but from what I can tell, this module only handles the title and body fields, and does this in a way that appear odd to me. Is there some common practice to solve this? I couldn't imagine that nobody had to solve this before, but I haven't found any good solution to it yet. Clarification I need this functionality for already existing content, that is, I want to be able to create and edit a draft version of an already published page, while the "old" version would still be available to anonymous users.

• Stata Nearest neighbor of percentile

  - by Kyle Billings

  This has probably already been answered, but I must just be searching for the wrong terms. Suppose I am using the built in Stata data set auto: sysuse auto, clear and say for example I am working with 1 independent and 1 dependent variable and I want to essentially compress down to the IQR elements, min, p(25), median, p(75), max... so I use command, keep weight mpg sum weight, detail return list local min=r(min) local lqr=r(p25) local med = r(p50) local uqr = r(p75) local max = r(max) keep if weight==`min' | weight==`max' | weight==`med' | weight==`lqr' | weight==`uqr' Hence, I want to compress the data set down to only those 5 observations, and for example in this situation the median is not actually an element of the weight vector. there is an observation above and an observation below (due to the definition of median this is no surprise). is there a way that I can tell stata to look for the nearest neighbor above the percentile. ie. if r(p50) is not an element of weight then search above that value for the next observation? The end result is I am trying to get the data down to 2 vectors, say weight and mpg such that for each of the 5 elements of weight in the IQR have their matching response in mpg. Any thoughts?

• How can I implement a volume meter for a song currently playing? (iPhone OS 3.1.3)

  Hi i'm very new to core audio and I just would like some help in coding up a little volume meter for whatever's being outputted through headphones or built-in speaker. Like a dB meter. I have the following code, and have been trying to go through the apple source project "SpeakHere", but it's a nightmare trying to go through all that, without knowing how it works first... Could anyone shed some light? Here's the code I have so far...

• Sql Exception: Error converting data type numeric to numeric

  - by Lucifer

  Hello We have a very strange issue with a database that has been moved from staging to production. The first time the database was moved it was by detaching, copying and reattaching, the second time we tried restoring from a backup of the staging.

• MySQL FULLTEXT not working

  - by Ross

  I'm attempting to add searching support for my PHP web app using MySQL's FULLTEXT indexes. I created a test table (using the MyISAM type, with a single text field a) and entered some sample data. Now if I'm right the following query should return both those rows: SELECT * FROM test WHERE MATCH(a) AGAINST('databases') However it returns none. I've done a bit of research and I'm doing everything right as far as I can tell - the table is a MyISAM table, the FULLTEXT indexes are set. I've tried running the query from the prompt and from phpMyAdmin, with no luck. Am I missing something crucial? UPDATE: Ok, while Cody's solution worked in my test case it doesn't seem to work on my actual table: CREATE TABLE IF NOT EXISTS `uploads` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` text NOT NULL, `size` int(11) NOT NULL, `type` text NOT NULL, `alias` text NOT NULL, `md5sum` text NOT NULL, `uploaded` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=6 ; And the data I'm using: INSERT INTO `uploads` (`id`, `name`, `size`, `type`, `alias`, `md5sum`, `uploaded`) VALUES (1, '04 Sickman.mp3', 5261182, 'audio/mp3', '1', 'df2eb6a360fbfa8e0c9893aadc2289de', '2009-07-14 16:08:02'), (2, '07 Dirt.mp3', 5056435, 'audio/mp3', '2', 'edcb873a75c94b5d0368681e4bd9ca41', '2009-07-14 16:08:08'), (3, 'header_bg2.png', 16765, 'image/png', '3', '5bc5cb5c45c7fa329dc881a8476a2af6', '2009-07-14 16:08:30'), (4, 'page_top_right2.png', 5299, 'image/png', '4', '53ea39f826b7c7aeba11060c0d8f4e81', '2009-07-14 16:08:37'), (5, 'todo.txt', 392, 'text/plain', '5', '7ee46db77d1b98b145c9a95444d8dc67', '2009-07-14 16:08:46'); The query I'm now running is: SELECT * FROM `uploads` WHERE MATCH(name) AGAINST ('header' IN BOOLEAN MODE) Which should return row 3, header_bg2.png. Instead I get another empty result set. My options for boolean searching are below: mysql> show variables like 'ft_%'; +--------------------------+----------------+ | Variable_name | Value | +--------------------------+----------------+ | ft_boolean_syntax | + -><()~*:""&| | | ft_max_word_len | 84 | | ft_min_word_len | 4 | | ft_query_expansion_limit | 20 | | ft_stopword_file | (built-in) | +--------------------------+----------------+ 5 rows in set (0.02 sec) "header" is within the word length restrictions and I doubt it's a stop word (I'm not sure how to get the list). Any ideas?

• git clone fails with "index-pack" failed?

  - by gct

  So I created a remote repo that's not bare (because I need redmine to be able to read it), and it's set to be shared with the group (so git init --shared=group). I was able to push to the remote repo and now I'm trying to clone it. If I clone it over the net I get this: remote: Counting objects: 4648, done. remote: Compressing objects: 100% (2837/2837), done. error: git-upload-pack: git-pack-objects died with error.B/s fatal: git-upload-pack: aborting due to possible repository corruption on the remote side. remote: aborting due to possible repository corruption on the remote side. fatal: early EOF fatal: index-pack failed I'm able to clone it locally without a problem, and I ran "git fsck", which only reports some dangling trees/blobs, which I understand aren't a problem. What could be causing this? I'm still able to pull from it, just not clone. I should note the remote git version is 1.5.6.5 while local is 1.6.0.4 I tried cloning my local copy of the repo, stripping out the .git folder and pushing to a new repo, then cloning the new repo and I get the same error, which leads me to believe it may be a file in the repo that's causing git-upload-pack to fail... Edit: I have a number of windows binaries in the repo, because I just built the python modules and then stuck them in there so everyone else didn't have to build them as well. If I remove the windows binaries and push to a new repo, I can clone again, perhaps that gives a clue. Trying to narrow down exactly what file is causing the problem now.

• What is a faster way of merging the values of this Python structure into a single dictionary?

  - by jcoon

  I've refactored how the merged-dictionary (all_classes) below is created, but I'm wondering if it can be more efficient. I have a dictionary of dictionaries, like this: groups_and_classes = {'group_1': {'class_A': [1, 2, 3], 'class_B': [1, 3, 5, 7], 'class_c': [1, 2], # ...many more items like this }, 'group_2': {'class_A': [11, 12, 13], 'class_C': [5, 6, 7, 8, 9] }, # ...and many more items like this } A function creates a new object from groups_and_classes like this (the function to create this is called often): all_classes = {'class_A': [1, 2, 3, 11, 12, 13], 'class_B': [1, 3, 5, 7, 9], 'class_C': [1, 2, 5, 6, 7, 8, 9] } Right now, there is a loop that does this: all_classes = {} for group in groups_and_classes.values(): for c, vals in group.iteritems(): for v in vals: if all_classes.has_key(c): if v not in all_classes[c]: all_classes[c].append(v) else: all_classes[c] = [v] So far, I changed the code to use a set instead of a list since the order of the list doesn't matter and the values need to be unique: all_classes = {} for group in groups_and_classes.values(): for c, vals in group.iteritems(): try: all_classes[c].update(set(vals)) except KeyError: all_classes[c] = set(vals) This is a little nicer, and I didn't have to convert the sets to lists because of how all_classes is used in the code. Question: Is there a more efficient way of creating all_classes (aside from building it at the same time groups_and_classes is built, and changing everywhere this function is called)?

• Best practice PHP Form Action

  - by Rob

  Hi there i've built a new script (from scratch not a CMS) and i've done alot of work on reducing memory usage and the time it takes for the page to be displayed (caching HTML etc) There's one thing that i'm not sure about though. Take a simple example of an article with a comments section. If the comment form posts to another page that then redirects back to the article page I won't have the problem of people clicking refresh and resending the information. However if I do it that way, I have to load up my script twice use twice as much memory and it takes twice as long whilst i'm still only displaying the page once. Here's an example from my load log. The first load of the article is from the cache, the second rebuilds the page after the comment is posted. Example 1 0 queries using 650856 bytes of memory in 0.018667 - domain.com/article/1/my_article.html 9 queries using 1325723 bytes of memory in 0.075825 - domain.com/article/1/my_article/newcomment.html 0 queries using 650856 bytes of memory in 0.029449 - domain.com/article/1/my_article.html Example 2 0 queries using 650856 bytes of memory in 0.023526 - domain.com/article/1/my_article.html 9 queries using 1659096 bytes of memory in 0.060032 - domain.com/article/1/my_article.html Obviously the time fluctuates so you can't really compare that. But as you can see with the first method I use more memory and it takes longer to load. BUT the first method avoides the refresh problem. Does anyone have any suggestions for the best approach or for alternative ways to avoid the extra load (admittadely minimal but i'd still like to avoid it) whilst also avoiding the refresh problem?
