• How can I use Django with MySQL in MAMP stack?

  - by Robert A Henru

  Hi all, I have difficulty especially in installing MySQLdb module (MySQL-python-1.2.3c1), to connect to the MySQL in MAMP stack. I've done a number of things such as copying the mysql include directory and library (including plugin) from a fresh installation of mysql (version 5.1.47) to the one inside MAMP (version 5.1.37). Now, the MySQLdb module build and install doesnt give me error. The error happens when I'm calling 'import MySQLdb' from python shell (version 2.6). Traceback (most recent call last): File "<stdin>", line 1, in <module> File "build/bdist.macosx-10.6-universal/egg/MySQLdb/__init__.py", line 19, in <module> File "build/bdist.macosx-10.6-universal/egg/_mysql.py", line 7, in <module> File "build/bdist.macosx-10.6-universal/egg/_mysql.py", line 6, in __bootstrap__ ImportError: dlopen(/Users/rhenru/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so, 2): Symbol not found: _mysql_affected_rows Referenced from: /Users/rhenru/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so Expected in: flat namespace in /Users/rhenru/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so Any idea, what else do I need to do to make it works? Thanks a bunch, Robert

• How do I process multipart http responses in Ruby Net:HTTP?

  - by seal-7

  There is so much information out there on how to generate multipart responses or do multipart file uploads. I can't seem to find any information on how to process a multipart http response. Here is some IRB output from a multipart http response I am working with. >> response.http.content_type => "multipart/related" >> response.http.body[0..2048] => "\r\n------=_Part_3_806633756.1271797659309\r\nContent-Type: text/xml; charset=UTF-8\r\nContent-Transfer-Encoding: binary\r\nContent-Id: <A0FCC4333C6D0FCA346B97FAB6B61818>\r\n\r\n<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><ns1:runReportResponse soapenv:encodingStyle="http://www.w3.org/2003/05/soap-encoding" xmlns:ns1="http://192.168.1.200:8080/jasperserver/services/repository"><ns2:result xmlns:ns2="http://www.w3.org/2003/05/soap-rpc">runReportReturn</ns2:result><runReportReturn xsi:type="xsd:string">&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;\n&lt;operationResult version=&quot;2.0.1&quot;&gt;\n\t&lt;returnCode&gt;&lt;![CDATA[0]]&gt;&lt;/returnCode&gt;\n&lt;/operationResult&gt;\n</runReportReturn></ns1:runReportResponse></soapenv:Body></soapenv:Envelope>\r\n------=_Part_3_806633756.1271797659309\r\nContent-Type: application/pdf\r\nContent-Transfer-Encoding: binary\r\nContent-Id: <report>\r\n\r\n%PDF-1.4\n%\342\343\317\323\n3 0 obj

• WPF DockPanel doesn't respect the "Filled" control's desired size

  - by Dan Puzey

  I have the following Xaml (simplified for brevity, but will repro the problem in Xamlpad or Kaxaml): <DockPanel Width="400"> <TextBlock DockPanel.Dock="Left" TextWrapping="Wrap"> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum massa metus, ornare in fringilla nec, fringilla at orci. Nunc pharetra enim sit amet sapien aliquet eu euismod turpis vehicula. Aenean gravida tempus lectus ut ornare. Nullam massa augue, suscipit vel consectetur fringilla, pretium vitae neque. </TextBlock> <Button MinWidth="100" VerticalAlignment="Center" HorizontalAlignment="Left">Hello world</Button> </DockPanel> My problem is that I want the Button to take its minimum 100px of space, and for the text to wrap suitably to leave that space. However, what happens is that the text wraps as close to 400px as possible, and then the Button is clipped. If I Snoop the output I can see that the button is rendering at the desired 100px, but it's being clipped off the side of the DockPanel. If I reverse the Dock (so the button is docked "Right" and the TextBlock fills) then I get the layout I want, but unfortunately that's not an option due to the surrounding layout. Is there something I can do that will make the DockPanel a) not clip and b) layout in a way that respects the MinWidth? Or am I stuck finding an alternative layout mechanism? Thanks in advance!

• XSLT Built-in Template Rules for attributes

  - by Martin Smith

  I'm sure that this is an extremely basic question but here goes anyway! I have read that the built in template rule for text and attribute nodes in XSLT is <xsl:template match="text()|@*"> <xsl:value-of select="."/> </xsl:template> However for the source document <?xml version="1.0"?> <booker> <award> <author blah="test">Aravind Adiga</author> <title>The White Tiger</title> <year>2008</year> </award> </booker> And XSLT <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text"/> </xsl:stylesheet> I get the following output applying the transform in Visual Studio. Can someone please explain why I don't see "test" in the output? Aravind Adiga The White Tiger 2008

• Why is this CHOICE element not getting assigned in my SharePoint Field definition schema?

  - by ccornet

  I defined a new field of the type "Choice" for my web application. It will serve basically as a pseudo-lookup as its contents are defined by the value of a Text field in a list. It is initialized with a dummy choice to begin with (I'm under the impression a choice field needs at least one choice when defined), which is replaced with a real choice later on. But for some reason, this dummy choice is never actually added to the choices! Below is the XML Schema for the field in question. <Field ID="{ALICEH-ASFA-KEGU-IDLISTED}" Name="ddlSystems" Group="Lookup Columns" DisplayName="ddlSystems" Type="Choice" Sealed="FALSE" ReadOnly="FALSE" Hidden="FALSE" FillInChoice="TRUE" DisplaceOnUpgrade="TRUE"> <CHOICES> <CHOICE>BLANULL</CHOICE> </CHOICES> <Default>BLANULL</Default> </Field> Initially, I used a default choice of (a single space), but I changed it to BLANULL so that I can parse an actual word instead of a veritably empty string. Now, even after having uninstalled and reinstalled the feature with this field, I have a choice field that has (still a single space) as the only choice. Even more perplexing, BLANULL is actually listed for the default value in both the UI and the object model! What is causing this problem, and how can I circumvent it so that I don't have to manually set this dummy value each time?

• latex padding / margin hell

  - by darren

  hi everyone I have been wrestling with a latex table for far too long. I need a table that has has centered headers, and body cells that contain text that may wrap around. Because of the wrap-around requirement, i'm using p{xxx} instead of l for specifying cell widths. The problem this causes is that cell contents are not left justified, so the look like spaced-out junk. To fix this problem I'm using \flushleft for each cell. This does left justify contents, but puts in a ton of white space above and below the contents of the cell. Is there a way to stop \flushleft (or \center for that matter) to stop adding copious amounts of verical whitespace? thanks \begin{landscape} \centering % using p{xxx} here to wrap long text instead of overflowing it \begin{longtable}{ | p{4cm} || p{3cm} | p{3cm} | p{3cm} | p{3cm} | p{3cm} |} \hline & % these are table headings. the \center is causing a ton of whitespace as well \begin{center} \textbf{HTC HD2} \end{center} & \begin{center} \textbf{Motorola Milestone} \end{center} & \begin{center} \textbf{Nokia N900} \end{center} & \begin{center} \textbf{RIM Blackberry Bold 9700} \end{center} & \begin{center} \textbf{Apple iPhone 3GS} \end{center} \\ \hline \hline % using flushleft here to left-justify, but again it is causing a ton of white space above and below cell contents. \begin{flushleft}OS / Platform \end{flushleft}& \begin{flushleft}Windows Mobile 6.5 \end{flushleft}& \begin{flushleft}Google Android 2.1 \end{flushleft}& \begin{flushleft}Maemo \end{flushleft}& \begin{flushleft}Blackberry OS 5.0 \end{flushleft}& \begin{flushleft}iPhone OS 3.1 \end{flushleft} \\ \hline

• What is the correct JNA mapping for UniChar on Mac OS X?

  - by Trejkaz

  I have a C struct like this: struct HFSUniStr255 { UInt16 length; UniChar unicode[255]; }; I have mapped this in the expected way: public class HFSUniStr255 extends Structure { public UInt16 length; // UInt16 is just an IntegerType with length 2 for convenience. public /*UniChar*/ char[] unicode = new char[255]; //public /*UniChar*/ byte[] unicode = new byte[255*2]; //public /*UniChar*/ UInt16[] unicode = new UInt16[255]; public HFSUniStr255() { } public HFSUniStr255(Pointer pointer) { super(pointer); } } If I use this version, I get every second character of the string into my char[] ("aits D" for "Macintosh HD".) I am assuming that this is something to do with being on a 64-bit platform and JNA mapping the value to a 32-bit wchar_t but then chopping off the high 16 bits on each wchar_t on copying them back. If I use the byte[] version, I get data which decodes correctly using the UTF-16LE charset. If I use the UInt16[] version, I get the right code point for each character but it is then inconvenient to convert them back into a string. Is there some way I can define my type as char[], and yet have it convert correctly?

• setlocale to fr-FR in PHP and number formatting

  - by bateman_ap

  Hi, I am trying to create a French version of one of my sites. I have set setlocale(LC_ALL, 'fr_FR'); at the top of my page, and using strftime I am displaying dates correctly in the French style. However I am having some problems with a number. Part of the page uses data I am getting from a Web Service. I am assigning a returned value to a var like this: $overallRating = $returnArray['Overall']; I am then using the following code later to format it to 1 decimal place number_format($overallRating,1) In the English version the overallRating value might be 7.5 and returns a value such as 7.5 (the reason for running it through the number_format is if it returns 7 I want it to display 7.0) However in the French version if I print out the raw $overallRating value I get 7,5 which looks like it has translated it into french. This would be fine but if I run it through number_format I get the error: Notice: A non well formed numeric value encountered in /sites/index.php on line 250 Line 250 is the number_format line I presume the translation to 7,5 is messing it up, but not sure how to solve this... Using PHP 5.3 in case there is anything new that helps me

• Can a large transaction log cause cpu hikes to occur

  - by Simon Rigby

  Hello all, I have a client with a very large database on Sql Server 2005. The total space allocated to the db is 15Gb with roughly 5Gb to the db and 10 Gb to the transaction log. Just recently a web application that is connecting to that db is timing out. I have traced the actions on the web page and examined the queries that execute whilst these web operation are performed. There is nothing untoward in the execution plan. The query itself used multiple joins but completes very quickly. However, the db server's CPU hikes to 100% for a few seconds. The issue occurs when several simultaneous users are working on the system (when I say multiple .. read about 5). Under this timeouts start to occur. I suppose my question is, can a large transaction log cause issues with CPU performance? There is about 12Gb of free space on the disk currently. The configuration is a little out of my hands but the db and log are both on the same physical disk. I appreciate that the log file is massive and needs attending to, but I'm just looking for a heads up as to whether this may cause CPU spikes (ie trying to find the correlation). The timeouts are a recent thing and this app has been responsive for a few years (ie its a recent manifestation). Many Thanks,

• Is MVC 2 client-side validation broken in Visual Studio 2010 RC?

  - by Will

  I can't seem to get client side validation working with the version of MVC released with Visual Studio 2010 RC. I've tried it with two projects -- one upgrade from 1.0, and one using the template that came with VS. I'd think the template version would work, but it doesn't. Added the following scripts: <script type="text/javascript" src="<%= Url.Content("~/Scripts/MicrosoftMvcValidation.js") %>"> </script> <script type="text/javascript" src="<%= Url.Content("~/Scripts/jquery.validate.js")%>"> </script> which are downloaded to the client correctly. Added the following to my form page: <% Html.EnableClientValidation(); %> <%--yes, am aware of the EndForm() bug! --%> <% using (Html.BeginForm()) { %> <%--snip --%> and I can see the client validation scripts have been added to the bottom of the form. But still client validation never happens. What is worse is that in my upgraded project, the client validation scripts are never output in the page! PLEASE NOTE: I am specifically asking about the version of MVC2 that came with VS2010 RC. Also, I do know how to google; please don't waste anybody's time searching and answering if you aren't familiar with this issue in the release candidate of Visual Studio. Thanks.

• PHP mySQL Error

  Hello, Im new to php so I decided to follow this tutorial for a simple login screen. I got the code setup but when I try login I get this error: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in (a long file path to the script) on line 27 The code I got from the tutorial is: <?php ob_start(); $host="thehost"; // Host name $username="myusername"; // Mysql username $password="mypass"; // Mysql password $db_name="test"; // Database name $tbl_name="members"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); // Define $myusername and $mypassword $myusername=$_POST['myusername']; $mypassword=$_POST['mypassword']; // To protect MySQL injection (more detail about MySQL injection) $myusername = stripslashes($myusername); $mypassword = stripslashes($mypassword); $myusername = mysql_real_escape_string($myusername); $mypassword = mysql_real_escape_string($mypassword); $sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" session_register("myusername"); session_register("mypassword"); header("location:login_success.php"); } else { echo "Wrong Username or Password"; } ob_end_flush(); ?> (Note: All of the mySQL database info is filled in on my version) Aslo, the author gives a php5 version and a normal php version. I have tried both and gotten the same error. If anyone knows why this is happening help is really appreciated.

I hope this question is relevant. :)

• Flex wordwrap issue with multiple text instances

  - by Craig Myles

  Hi, I have a scenario where I want to dynamically add words of text to a container so that it forms a paragraph of text which is wrapped neatly according to the size of the parent container. Each text element will have differing formatting, and will have differing user interaction options. For example, imagine the text " has just spoken out about ". Each word will be added to the container one at a time, at run time. The username in this case would be bold, and if clicked on will trigger an event. Same with the news article. The rest of the text is just plain text which, when clicked on, would do nothing. Now, I'm using Flex 3 so I don't have access to the fancy new text formatting tools. I've implemented a solution where the words are plotted onto a canvas, but this means that the words are wrapped at a particular y position (an arbitrary value I've chosen). When the container is resized, the words still wrap at that position which leaves lots of space. I thought about adding each text element to an Array Collection and using this as a datasource for a Tile List, but Tile Lists don't support variable column widths (in my limited knowledge) so each word would use the same amount of space which isn't ideal. Does anyone know how I can plot words onto a container so that I can retain formatting, events and word wrapping at paragraph level, even if the container is resized?

• Latex: Text cannot be placed below image

  - by Frederik Wordenskjold

  I love latex! But sometimes, it does not love me... I'm having a problem with an image and some text. I have this code: Some text...\\ \begin{figure}[ht] \centering \includegraphics[scale=0.75]{picture.jpg} \caption{The caption} \label{fig:picture} \end{figure} Some more text... Basically, I want this: Some text. (Above image in the code) [end of page / new page] image Some more text. (Below the image in the code) [start of new section] But, what the above code gives me is this: Some text. (Above image in the code) Some more text. (Below the image in the code) [end of page / new page] image [start of new section] Latex insists on putting everything but a new section above the image even though its below the image in the code. Its probably because the image floats on top - but whats my alternative? There's not enough space on the first page to display the image there, to I cannot use [h] as the float-alignment. I can "hack it", by creating an empty new section, like \section*{}, but this creates some white-space, which looks weird. Any suggestions?

• Open PDF Content files in ASP.NET MVC 2

  - by mcbingo

  I want to provide simple href links to my PDF forms that reside in my Forms folder. I have a created a simple Index.aspx and FormController Index action that simple iterates through the list of PDF files using my FormMetaData.xml file. The links get created just fine but when you click on the links I get a 404 exception. That looks like this: Server Error in '/' Application. The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /Forms/ccindteamgolfform.pdf Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927 This seems like this should open up a new browser window with the PDF in it but perhaps I am making a bad assumption. The PDF content files have Build Action of Content and Copy to Output set to Copy Always. Here is an example output html for the link from my Index.aspx page: <span class="form"> <a href="Forms/ccindteamgolfform.pdf" target="_blank"> <span class="description">Entry Form</span></span> I must be missing something because this does not work. Do I need to add a MapRoute for these documents? Or am I missing something else with the routing? This seems like it should not be that difficult.

• RSS feed generated by SharePoint has a stylesheet tag and how to remove that

  - by iHeartDucks

  The feed which SharePoint Generates is here (I copied it to pastie because I thought it would be clear there) However, the xml file comes with a style sheet tag. How do I remove that? Does SharePoint always generate that? Due to the presence of that tag, I am unable to apply another style sheet of my own using the XML WebPart. EDIT: I don't think the issue is related to the style sheet. If I copy the xml and paste it in the "Xml Editor" of the Web Part everything works just fine. If I provide the URL, that is when I do not see any data.

• Setting up Mercurial/TortoiseHg to work with UltraCompare

  Hi, I'm trying to get my favorite Windows diff/merge tool, UltraCompare (V7.00) to work with Mercurial/TortoiseHg. I have set up UltraCompare in my Mercurial.ini like this (only relevant bits shown): [merge-tools] UltraCompare.executable = C:\Programme\IDM Computer Solutions\UltraCompare\uc.com UltraCompare.args = $base $local $other UltraCompare.priority = 1 UltraCompare.gui = True UltraCompare.binary = True UltraCompare.checkconflicts = True UltraCompare.checkchanged = True However, the three-way-merge fails. The path names get messed up if the path to the repository that is being merged to contains a space. I have done some more testing, and I've found out (using Process Explorer) that uc.com is called with a broken command line if there is a space in the repository's path: Compare "C:\Programme\IDM Computer Solutions\UltraCompare\uc.exe" " "c:\dokume~1\tim~1.pie\lokale~1\temp\test.txt~base.akr6au" "E:\Eigene Dateien\test\test-merge\test.txt" "c:\dokume~1\tim~1.pie\lokale~1\temp\test.txt~other.b92442" and "C:\Programme\IDM Computer Solutions\UltraCompare\uc.com" "c:\dokume~1\tim~1.pie\lokale~1\temp\test.txt~base.e7vryp" "E:\test\test-merge\test.txt" "c:\dokume~1\tim~1.pie\lokale~1\temp\test.txt~other.u_qxme" There is an extraneous " after the path of the executable in the first example - not in the second (which works fine). To me, it seems as if UltraCompare is doing everything right, and that Mercurial/TortoiseHg are passing a defective command line to it. Would you say so, too? Is there a workaround? I've just updated to Mercurial 1.5/TortoiseHg 1.0, and the problem persists. Support for other merge tools (Beyond Compare and others) has been added, sadly not UltraCompare...

• How to populate data from .txt file into Excel in VBA?

  - by swei

  I'm trying to create something to read data from a .txt file, then populate data into .xls, but after open the .txt file, how do I get the data out? Basically I'm trying to get the the third column of the lines dated '04/06/2010'. After I open the .txt file, when I use ActiveSheet.Cells(row, col), the ActiveSheet is not pointing to .txt file. My .txt file is like this (space delimited): 04/05/10 23 29226 04/05/10 24 26942 04/06/10 1 23166 04/06/10 2 22072 04/06/10 3 21583 04/06/10 4 21390 Here is the code I have: Dim BidDate As Date BidDate = '4/6/2010' Workbooks.OpenText Filename:=ForecastFile, StartRow:=1, DataType:=xlDelimited, Space:=True If Err.Number = 1004 Then MsgBox ("The forecast file " & ForecastFile & " was not found.") Exit Sub End If On Error GoTo 0 Dim row As Integer, col As Integer row = 1 col = 1 cell_value = activeSheet.Cells(row, col) MsgBox ("the cell_value=" & cell_value) Do While (cell_value <> BidDate) And (cell_value <> "") row = row + 1 cell_value = activeSheet.Cells(row, col) ' MsgBox ("the value is " & cell_value) Loop If cell_value = "" Then MsgBox ("A load forecast for " & BidDate & " was not found in your current load forecast file titled '" + ForecastFile + ". " + "Make sure you have a load forecast for the current bid date and then open this spreadsheet again.") ActiveWindow.Close Exit Sub End If Can anyone point out where it goes wrong here?

• uninitialized constant Test::Unit::TestResult::TestResultFailureSupport

  - by Vitaly Kushner

  I get the error in subj when I'm trying to run specs or generators in a fresh rails project. This happens when I add shoulda to the mix. I added the following in the config/environment.rb: config.gem 'rspec', :version => '1.2.6', :lib => false config.gem 'rspec-rails', :version => '1.2.6', :lib => false config.gem "thoughtbot-shoulda", :version => "2.10.2", :lib => 'shoulda', :source => "http://gems.github.com" I'm on OSX. ruby 1.8.6 (2008-08-11 patchlevel 287) gems 1.3.5 rails 2.3.4 rspec - 1.2.6 shoulda - 2.10.2 test-unit - 2.0.3 I'm aware of this and adding config.gem 'test-unit', :lib => 'test/unit' indeed solves the genrator problem as it doesn't throw an exception, but it prints 0 tests, 0 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications at the end of the run so I suppose it tries to run tests which is unexpected and undesired, also the specs stop to run at all, seems like rspec is not running at all, when running rake spec I get the test-unit output again (with 0 tests as there are only specs, no tests defined)

• Where should you put 3rd party .NET dlls when using git submodules to avoid duplication

  - by Tim Abell

  I have two .NET library projects in Visual Studio 2008 that both make use of the MySql Connector for .NET (MySql.Data.dll). These libraries are then in turn both used by a .NET command line application which also uses the Connector. The library projects are pulled in to the application's solution as git submodules and referenced by project in Visual Studio. I'm looking for the most effective strategy for storing and referencing the MySql Connector library. I have tried having the MySql.Data.dll checked in to all three projects (in their root folder), this was problematic when one project changed to a newer version of the connector dll. Although each project had its own version of the dll, only one was packaged into the resultant application leading to an API mismatch which was hard to pin down. This has put me off this approach. I have tried having the command line application reference the connector dll that is held in a submodule, however this only removes the possibility of version mismatches when there is only one submodule rather than two as in this case. I am contemplating putting the dll in the global assembly cache (GAC) of all machines that need to build or use the application, but I'm wary of not having all dependencies for an application available in source control.

• Alternative to as3isolib?

  - by tedw4rd

  Hi everyone, I've been working on a Flash game that involves an isometric space. I've been using as3isolib for a while now, and I'm less than impressed with how easy it is to use. Whether I'm approaching it the wrong way or it's just not that great to use is a question for another post. Anyways, I've been thinking of a different way to approach the problem of isometric positions, and I think I've got an idea that might work. Essentially, each object that is to be rendered to the iso-space maintains a 3-coordinate position. Those items are then registered with a camera that projects that 3-coordinate position to a 2-coordinate point on the screen according to the math on this Wikipedia article. Then, the MovieClip is added to the stage (or to the camera's MovieClip, perhaps) at that point, and at a child index of the point's y-value. That way, I figure objects that are closer to the camera will be "above" the objects further away, and will get rendered over them. So my question, then, is two-fold: Do you think this idea will work the way I think it will? Are there any existing 3D matrix/vector packages that I should look at? I know there's a Matrix3 class in Flex 3, but we're not using Flex for this game. Thanks!

• Mysql InnoDB performance optimization and indexing

  - by Davide C

  Hello everybody, I have 2 databases and I need to link information between two big tables (more than 3M entries each, continuously growing). The 1st database has a table 'pages' that stores various information about web pages, and includes the URL of each one. The column 'URL' is a varchar(512) and has no index. The 2nd database has a table 'urlHops' defined as: CREATE TABLE urlHops ( dest varchar(512) NOT NULL, src varchar(512) DEFAULT NULL, timestamp timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, KEY dest_key (dest), KEY src_key (src) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 Now, I need basically to issue (efficiently) queries like this: select p.id,p.URL from db1.pages p, db2.urlHops u where u.src=p.URL and u.dest=? At first, I thought to add an index on pages(URL). But it's a very long column, and I already issue a lot of INSERTs and UPDATEs on the same table (way more than the number of SELECTs I would do using this index). Other possible solutions I thought are: -adding a column to pages, storing the md5 hash of the URL and indexing it; this way I could do queries using the md5 of the URL, with the advantage of an index on a smaller column. -adding another table that contains only page id and page URL, indexing both columns. But this is maybe a waste of space, having only the advantage of not slowing down the inserts and updates I execute on 'pages'. I don't want to slow down the inserts and updates, but at the same time I would be able to do the queries on the URL efficiently. Any advice? My primary concern is performance; if needed, wasting some disk space is not a problem. Thank you, regards Davide

• Is it possible to store pointers in shared memory without using offsets?

  - by Joseph Garvin

  When using shared memory, each process may mmap the shared region into a different area of their address space. This means that when storing pointers within the shared region, you need to store them as offsets of the start of the shared region. Unfortunately, this complicates use of atomic instructions (e.g. if you're trying to write a lock free algorithm). For example, say you have a bunch of reference counted nodes in shared memory, created by a single writer. The writer periodically atomically updates a pointer 'p' to point to a valid node with positive reference count. Readers want to atomically write to 'p' because it points to the beginning of a node (a struct) whose first element is a reference count. Since p always points to a valid node, incrementing the ref count is safe, and makes it safe to dereference 'p' and access other members. However, this all only works when everything is in the same address space. If the nodes and the 'p' pointer are stored in shared memory, then clients suffer a race condition: x = read p y = x + offset Increment refcount at y During step 2, p may change and x may no longer point to a valid node. The only workaround I can think of is somehow forcing all processes to agree on where to map the shared memory, so that real pointers rather than offsets can be stored in the mmap'd region. Is there any way to do that? I see MAP_FIXED in the mmap documentation, but I don't know how I could pick an address that would be safe.
