  • TStringList and TThread that does not free all of its memory

    - by VanillaH
    Version used: Delphi 7. I'm working on a program that does a simple for loop on a Virtual ListView. The data is stored in the following record: type TList=record Item:Integer; SubItem1:String; SubItem2:String; end; Item is the index. SubItem1 the status of the operations (success or not). SubItem2 the path to the file. The for loop loads each file, does a few operations and then, save it. The operations take place in a TStringList. Files are about 2mb each. Now, if I do the operations on the main form, it works perfectly. Multi-threaded, there is a huge memory problem. Somehow, the TStringList doesn't seem to be freed completely. After 3-4k files, I get an EOutofMemory exception. Sometimes, the software is stuck to 500-600mb, sometimes not. In any case, the TStringList always return an EOutofMemory exception and no file can be loaded anymore. On computers with more memory, it takes longer to get the exception. The same thing happens with other components. For instance, if I use THTTPSend from Synapse, well, after a while, the software cannot create any new threads because the memory consumption is too high. It's around 500-600mb while it should be, max, 100mb. On the main form, everything works fine. I guess the mistake is on my side. Maybe I don't understand threads enough. I tried to free everything on the Destroy event. I tried FreeAndNil procedure. I tried with only one thread at a time. I tried freeing the thread manually (no FreeOnTerminate...) No luck. So here is the thread code. It's only the basic idea; not the full code with all the operations. If I remove the LoadFile prodecure, everything works good. A thread is created for each file, according to a thread pool. unit OperationsFiles; interface uses Classes, SysUtils, Windows; type TOperationFile = class(TThread) private Position : Integer; TPath, StatusMessage: String; FileStringList: TStringList; procedure UpdateStatus; procedure LoadFile; protected procedure Execute; override; public constructor Create(Path: String; LNumber: Integer); end; implementation uses Form1; procedure TOperationFile.LoadFile; begin try FileStringList.LoadFromFile(TPath); // Operations... StatusMessage := 'Success'; except on E : Exception do StatusMessage := E.ClassName; end; end; constructor TOperationFile.Create(Path : String; LNumber: Integer); begin inherited Create(False); TPath := Path; Position := LNumber; FreeOnTerminate := True; end; procedure TOperationFile.UpdateStatus; begin FileList[Position].SubItem1 := StatusMessage; Form1.ListView4.UpdateItems(Position,Position); end; procedure TOperationFile.Execute; begin FileStringList:= TStringList.Create; LoadFile; Synchronize(UpdateStatus); FileStringList.Free; end; end. What could be the problem? I thought at one point that, maybe, too many threads are created. If a user loads 1 million files, well, ultimately, 1 million threads is going to be created -- although, only 50 threads are created and running at the same time. Thanks for your input.

  • Easy to use/learn PHP framework?

    - by Meredith
    I need to build a php app, and I was thinking about using a framework (never used one before). I've been browsing around some but most of them seems kinda complicated, I really liked what I saw about Symfony, but it looks like I will have to spend like a month until I really understand how to use it, and in one month I could code the app I have in mind 5 times without a framework. But I want to use one to "standardize" my code and prevent bugs. So I was wondering if someone could share with me which php frameworks you think are easier to learn how to use. My application will use mysql, and it will have some sort of "search engine" to search data that will be populated on the database using a few "scraper scripts" (that I also wants to code using the framework).

  • Java Program Compiles and Runs, but doesn't work

    - by Richard Long
    When I run this program I enter information in a text box, push the search button, but nothing happens. The program just sits there until I press Cntrl C to break it. It looks like it should work, but I can't figure out what is hanging the program up. Here is the code: First class: import java.io.*; import java.awt.*; import javax.swing.*; import java.awt.event.*; import java.util.*; public class NameGameFrame extends JFrame { public static String name; static JTextField textfield = new JTextField(20); static JTextArea textarea = new JTextArea(30,30); public static String num; public static String [] fields; public static int [] yearRank; public static boolean match; public static int getInts, marker, year, max; public static void main( String[] args) { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setTitle("Name Game"); frame.setLocation(500,400); frame.setSize(800,800); JPanel panel = new JPanel(new GridBagLayout()); GridBagConstraints c = new GridBagConstraints(); JLabel label = new JLabel("Enter the Name or Partial Name to search:"); c.gridx = 0; c.gridy = 0; c.insets = new Insets(2,2,2,2); panel.add(label,c); c.gridx = 0; c.gridy = 1; panel.add(textarea,c); JButton button = new JButton("Search"); c.gridx = 1; c.gridy = 1; panel.add(button,c); c.gridx = 1; c.gridy = 0; panel.add(textfield,c); frame.getContentPane().add(panel, BorderLayout.NORTH); frame.pack(); frame.setVisible(true); button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent ae) { name = textfield.getText(); java.io.File file = new java.io.File("namesdata.txt"); try { Scanner input = new Scanner(file); num = input.nextLine(); NameRecord nr = new NameRecord(name); while (input.hasNext()) { if(match = num.toLowerCase().contains(name.toLowerCase())) { nr.getRank(); nr.getBestYear(marker); } } } catch(FileNotFoundException e) { System.err.format("File does not exist\n"); } textarea.setText(fields[0]); } }); } } This is the second class: import java.io.*; import java.util.*; public class NameRecord { public NameRecord( String name) { } public static int getBestYear(int marker) { switch (marker) { case 1: year = 1900; break; case 2: year = 1910; break; case 3: year = 1920; break; case 4: year = 1930; break; case 5: year = 1940; break; case 6: year = 1950; break; case 7: year = 1960; break; case 8: year = 1970; break; case 9: year = 1980; break; case 10: year = 1990; break; case 11: year = 2000; break; } return year; } public static int getRank() { fields = num.split(" "); max = 0; for (int i = 1; i<12; i++) { getInts = Integer.parseInt(fields[i]); if(getInts>max) { max = getInts; marker = i; } } return max; } }

  • Moved X-cart site to Sub Directory - Need Help setting up Redirects

    - by Rich G
    I recently moved an x-cart site from a root directory to a sub directory, and also built a new Wordpress site under the root directory. The problem I am having is that I am trying to figure out a redorect combo that will show the search engines that the product pages are now under the sub directory (/store) but do not want the search engines to exclude the brand new site under the Root directory. I was thinking that if I could just have redirect any .html file (all of the product pages link to .html pages) that it would redirect to the same page just under the sub directory. The reason I cannot do everything one by one is because there are about 50k+ products that would need be changed. Any information and help would be greatly appreciated! Thank you in advanced!

  • How to use NGramTokenizerFactory or NGramFilterFactory?

    - by user572485
    Hi, Recently, I am studying how to store and index using Solr. I want to do facet.prefix search. With whitespace tokenizer, "Where are you" will be splited into three words and indexed. If I search facet.prefix="where are", no result will be returned. I google and found NGramFilterFactory can help me. But when I apply this filter factory, I found the result is "w, h, e, ..., wh, ..", which split the sentence by character, not by token word. I use the parameters maxGramSize and minGramSize, set to 1 and 3. Does the NGramFilterFactory work right? Should I add some other parameters? Is there some other filter factories which can help me? Thanks!

  • Paginating with SQL ROW_NUMBER

    - by Kelsey Thorpe
    I want to return search results in paginated format. However I can't seem to successfully get the first 10 results of my query. The problem is the 'RowNum' returned are like 405, 687, 1024 etc. I want them to be renumbered as 1,2,3,4,5 etc., so that when I specify between rows 1 and 20 i get the first 20 search results. Instead, because the numbers are larger, I get no results between 1 and 10. If i change RowNum condition to: AND RowNum < 20000 I get plenty of results Here's the sql: SELECT * FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY DocumentID ) AS RowNum, * FROM Table ) AS RowConstrainedResult WHERE RowNum >= 1 AND RowNum < 20 AND Title LIKE '%diabetes%' AND Title LIKE '%risk%' Any help appreciated.

  • Redirecting a large number of URLs with htaccess or php header

    - by Peter
    I have undergone a major website overhaul and now have 5,000+ incoming links from search engines and external sites, bookmark services etc that lead to dead pages or 404 errors. A lot of the pages have corresponding "permalinks" or known replacement hierarchy/URL structure. I've started to list the main redirects with htaccess or physical files with simply a header location reidrect which is clearly not sustainable! What would be the best method to list all of the old link addresses and their corresponding new addresses with htaccess, php headers, mysql, sitemap file or is it better to have all broken links and wait for search engines etc to re-index my site? Are there any implications for having a large number of redirecting files for this temporary period until links are reset?

  • JSF - Updating Model Values in Controller Bean

    - by Sean
    I have a Controller bean (SearchController) that has two managed bean as managed properties (SearchCriteria, SearchResults; both of which are session scoped). When the user hits the find button, the action method that is executed is in SearchController. The SearchCreteria managed bean has a method called search(). This method returns a new SearchResults object. In the controller bean, I am setting the searchResults managed property to be this new SearchResults object. The searchResults object contains what I expect during that request, but the object does not persist in the managed bean. I understand that I am changing what object that searchResults is referencing, but what I don't understand is why JSF isn't updating the model to use the new object. Any ideas what I'm missing or don't understand? I am using JSF 1.1 on WebSphere 6.1. If I put the search method in the SearchResults managed bean, it works.

  • silverlight vs ASP.NET MVC

    - by magellings
    I'm debating whether to use Silverlight 2.0 vs ASP.NET MVC for a web application. The web application will be a subscription free service marketing all age groups. It's important the source is highly testable, but also with the Web 2.0 movement a graphical web application is important as well for competitive reasons. I'm assuming silverlight is better than the ajax helpers/MVC graphically, but foundation-wise testing is better/easier with MVC. Possibly an MVP pattern with Silverlight could increase the testability of the source. Could anyone elaborate on the pros/cons of each technology and recommend one or the other based on the above? (addition 9/22/08) In regards to allowing search engines to index the site, using either technology it will utilize a backend database whereas a lot of the content will be dynamically generated. Based on some of the comments, when we talk of the searchable content would the home page of the application if written in silverlight be searchable? Would I be able to get the site to appear in a google search?

  • [SEO] sitemap.xml What is the precision of the priority field?

    - by Christoph
    Unfortunately the specification does not tell anything about precision. The xml scheme definition states that it is of the type xsd:decimal: <xsd:restriction base="xsd:decimal"> <xsd:minInclusive value="0.0"/> <xsd:maxInclusive value="1.0"/> </xsd:restriction> I have a sitemap generator that uses up to 10 positions after decimal point. Where often only the last few positions differ. These numbers are perfectly right according to the xsd, but yet i found some pages(3,4) that state that only 0.0, 0.1, 0.2, .., 1.0 are valid values. How will the search engines react to such a sitemap? Will some just round the value? I know that it is unlikely that someone can provide an answer to that question, unless he works for that search engine, but i think experiences will also do.

  • How to get MVC action to return 404

    - by zaph0d
    I have an action that takes in a string that is used to retrieve some data. If this string results in no data being returned (maybe because it has been deleted), I want to return a 404 and display an error page. I currently just use return a special view that display a friendly error message specific to this action saying that the item was not found. This works fine, but would ideally like to return a 404 status code so search engines know that this content no longer exists and can remove it from the search results. What is the best way to go about this? Is it as simple as setting Response.StatusCode = 404?

  • How do you encode an apostrophe so that it's searchable in mysql?

    - by Yegor
    I don't think that was the most clear question, but an example should make it a little clearer. I have a table filled with movie names, some of which contain apostrophes. I have a search box which is used to find movies. If I perform searches via mov_title = '$search_keywords' it all works, but this method will not yield any results for partial searches, so I have to use this mov_title LIKE '%$search_keywords%' This method works fine for titles that are A-Za-z0-9, but if a title has an apostrophe, it's not able to find the movie, even if I do an exact match. Before the titles are stored in the DB, I put them through this: $search_keywords = htmlspecialchars(mysql_escape_string($_GET["search_keywords"])); So in the DB, there is a forward slash before every single apostrophe. The only way to match a movie title with an apostrophe is to physically put a forward slash in front of the apostrophe, in the search box. This seems so trivial, and I'm sure the solution is painfully obvious, but I'm just not seeing it.

  • JPA 2.1 Schema Generation (TOTD #187)

    - by arungupta
    This blog explained some of the key features of JPA 2.1 earlier. Since then Schema Generation has been added to JPA 2.1. This Tip Of The Day (TOTD) will provide more details about this new feature in JPA 2.1. Schema Generation refers to generation of database artifacts like tables, indexes, and constraints in a database schema. It may or may not involve generation of a proper database schema depending upon the credentials and authorization of the user. This helps in prototyping of your application where the required artifacts are generated either prior to application deployment or as part of EntityManagerFactory creation. This is also useful in environments that require provisioning database on demand, e.g. in a cloud. This feature will allow your JPA domain object model to be directly generated in a database. The generated schema may need to be tuned for actual production environment. This usecase is supported by allowing the schema generation to occur into DDL scripts which can then be further tuned by a DBA. The following set of properties in persistence.xml or specified during EntityManagerFactory creation controls the behaviour of schema generation. Property Name Purpose Values javax.persistence.schema-generation-action Controls action to be taken by persistence provider "none", "create", "drop-and-create", "drop" javax.persistence.schema-generation-target Controls whehter schema to be created in database, whether DDL scripts are to be created, or both "database", "scripts", "database-and-scripts" javax.persistence.ddl-create-script-target, javax.persistence.ddl-drop-script-target Controls target locations for writing of scripts. Writers are pre-configured for the persistence provider. Need to be specified only if scripts are to be generated. java.io.Writer (e.g. MyWriter.class) or URL strings javax.persistence.ddl-create-script-source, javax.persistence.ddl-drop-script-source Specifies locations from which DDL scripts are to be read. Readers are pre-configured for the persistence provider. java.io.Reader (e.g. MyReader.class) or URL strings javax.persistence.sql-load-script-source Specifies location of SQL bulk load script. java.io.Reader (e.g. MyReader.class) or URL string javax.persistence.schema-generation-connection JDBC connection to be used for schema generation javax.persistence.database-product-name, javax.persistence.database-major-version, javax.persistence.database-minor-version Needed if scripts are to be generated and no connection to target database. Values are those obtained from JDBC DatabaseMetaData. javax.persistence.create-database-schemas Whether Persistence Provider need to create schema in addition to creating database objects such as tables, sequences, constraints, etc. "true", "false" Section 11.2 in the JPA 2.1 specification defines the annotations used for schema generation process. For example, @Table, @Column, @CollectionTable, @JoinTable, @JoinColumn, are used to define the generated schema. Several layers of defaulting may be involved. For example, the table name is defaulted from entity name and entity name (which can be specified explicitly as well) is defaulted from the class name. However annotations may be used to override or customize the values. The following entity class: @Entity public class Employee {    @Id private int id;    private String name;     . . .     @ManyToOne     private Department dept; } is generated in the database with the following attributes: Maps to EMPLOYEE table in default schema "id" field is mapped to ID column as primary key "name" is mapped to NAME column with a default VARCHAR(255). The length of this field can be easily tuned using @Column. @ManyToOne is mapped to DEPT_ID foreign key column. Can be customized using JOIN_COLUMN. In addition to these properties, couple of new annotations are added to JPA 2.1: @Index - An index for the primary key is generated by default in a database. This new annotation will allow to define additional indexes, over a single or multiple columns, for a better performance. This is specified as part of @Table, @SecondaryTable, @CollectionTable, @JoinTable, and @TableGenerator. For example: @Table(indexes = {@Index(columnList="NAME"), @Index(columnList="DEPT_ID DESC")})@Entity public class Employee {    . . .} The generated table will have a default index on the primary key. In addition, two new indexes are defined on the NAME column (default ascending) and the foreign key that maps to the department in descending order. @ForeignKey - It is used to define foreign key constraint or to otherwise override or disable the persistence provider's default foreign key definition. Can be specified as part of JoinColumn(s), MapKeyJoinColumn(s), PrimaryKeyJoinColumn(s). For example: @Entity public class Employee {    @Id private int id;    private String name;    @ManyToOne    @JoinColumn(foreignKey=@ForeignKey(foreignKeyDefinition="FOREIGN KEY (MANAGER_ID) REFERENCES MANAGER"))    private Manager manager;     . . . } In this entity, the employee's manager is mapped by MANAGER_ID column in the MANAGER table. The value of foreignKeyDefinition would be a database specific string. A complete replay of Linda's talk at JavaOne 2012 can be seen here (click on CON4212_mp4_4212_001 in Media). These features will be available in GlassFish 4 promoted builds in the near future. JPA 2.1 will be delivered as part of Java EE 7. The different components in the Java EE 7 platform are tracked here. JPA 2.1 Expert Group has released Early Draft 2 of the specification. Section 9.4 and 11.2 provide all details about Schema Generation. The latest javadocs can be obtained from here. And the JPA EG would appreciate feedback.

  • Regarding Standard Oxford Format for vlfeat sift

    - by Karl
    One of my upper classmen has gave me a data set for experimenting with vlfeat's SIFT, however, her extracted SIFT data for the frame part contains 5 dimensions. Recall from vl_sift function: [F,D] = VL_SIFT(I) Each column of D is the descriptor of the corresponding frame in F. F normally contains 4 dimensions which consists of x-coordinate, y-coordinate, scale, and orientation. So I asked her what is this 5th dimension, and she pointed me to search for "standard oxford format" for sift feature. The thing is I tried to search around regarding this standard oxford format and sift feature, but I got no luck in finding it at all. If somebody knows regarding this, could you please point me to the right direction?
