  • How to search cvs comment history

    - by Chris Noe
    I am aware of this command: cvs log -N -w<userid> -d"1 day ago" Unfortunately this generates a formatted report with lots of newlines in it, such that the file-path, the file-version, and the comment-text are all on separate lines. Therefore it is difficult to scan it for all occurrences of comment text, (eg, grep), and correlate the matches to file/version. (Note that the log output would be perfectly acceptable, if only cvs could perform the filtering natively.) EDIT: Sample output. A block of text like this is reported for each repository file: RCS file: /data/cvs/dps/build.xml,v Working file: build.xml head: 1.49 branch: locks: strict access list: keyword substitution: kv total revisions: 57; selected revisions: 1 description: ---------------------------- revision 1.48 date: 2008/07/09 17:17:32; author: noec; state: Exp; lines: +2 -2 Fixed src.jar references ---------------------------- revision 1.47 date: 2008/07/03 13:13:14; author: noec; state: Exp; lines: +1 -1 Fixed common-src.jar reference. =============================================================================

  • General JDBC Setup

    - by AeroDroid
    So I have a MySQL database set up on a Debian server and it works fine from a phpMyAdmin client. I'm currently working on a project to write a Java server that would be able to use the MySQL database that is already on this server through a JDBC connection. I've looked at many tutorials and documentations but all of them seem to just explain how to do client-side code, but I have yet to figure out how to even successfully open a JDBC connection to the server. As far as I am concerned, I believe that program has the drivers properly set up because it's not crashing anymore (I simply direct the Java Build Path of my program to the Connector/J provided by MySQL). As far as my program goes, this is what it looks like... import java.sql.*; public class JDBCTest { public static void main(String[] args) { System.out.println("Started!"); try { DriverManager.registerDriver(new com.mysql.jdbc.Driver()); System.out.println("Driver registered. Connecting..."); Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/", "root", "password"); System.out.println("Connected!"); conn.close(); } catch (SQLException e) { System.out.println("Error!"); e.printStackTrace(); } } } This is what's printed... Started! Driver registered. Connecting... It's as if the DriverManager.getConnection(String) just freezes there. I'm sure this is a problem with the server because when I intentionally misspell localhost, or an IP address, the program crashes within 20 seconds. This just hangs there forever. Sorry about this wall of text, but my final question is if anyone has any information what I should do or install on the server to get this to work? Thank you so much!

  • jquery touch punch - draggable on ipad

    - by dshuta
    i am starting to work with the jquery touch punch extensions in order to allow draggability on ipad, but i am getting tripped up right away. probably something terribly dumb on my part. the draggable example from the developer works fine on my ipad: http://furf.com/exp/touch-punch/draggable.html but not for me: http://danshuta.com/touchpunch/ this works fine in my desktop browser, but on the ipad it just focuses on the block and scrolls the entire page as i drag, as if it were just an image or other normal embedded object. as this is what happens normally with jquery/ui on ipad, this makes me think it is not loading or otherwise ignoring the "punch" code from my site (though if i host the jquery files on my site via the same path, those load and function fine in desktop browser). here's the entire code, very basic: <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <title>Touchpunchtest</title> <script src="http://code.jquery.com/jquery.min.js"></script> <script src="http://code.jquery.com/ui/1.8.17/jquery-ui.min.js"></script> <script src="js/jquery.ui.touch-punch.js"></script> </head> <body> <div id="draggybox" onclick="void(0)" style="width: 150px; height: 150px; background: green;"></div> <script>$('#draggybox').draggable();</script> </body> </html> what am i missing?!

  • Setting directory security to allow user and deny all

    - by Rita
    I have winforms app, in which I need to access a secured directory. I'm using impersonation and create WindowsIdentity to access the folder. My problem is writing unit tests to test the directory security; I'd like to a write a code that creates a directory secured to only ONE user, which isn't the current user running the UT (or else the test would be worthless). I know how to add permissions to a certain user, but how can I deny the rest, including admins? (in case the user running the UT is an admin) (will this be a wise thing to do?) DirectoryInfo directoryInfo = new DirectoryInfo(path); DirectorySecurity directorySecurity = directoryInfo.GetAccessControl(); directorySecurity.AddAccessRule(new FileSystemAccessRule("Domain\SecuredUser", FileSystemRights.FullControl, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow)); directorySecurity.RemoveAccessRule(new FileSystemAccessRule("??", FileSystemRights.FullControl, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Deny)); directoryInfo.SetAccessControl(directorySecurity); This isn't working. I don't know who am I supposed to deny. Domain\Admins, Domain\Administrators, me... No one is being denied, and when I check folder's security - The SecuredUser has access to the folder, but the permissions are not checked, even though I specified FullControl. Basically I want to code this: <authorization> <allow users ="Domain\User" /> <deny users="*" /> </authorization> I was thinking about impersonating UT run with a weak user with no permissions, but this would result in: Impersonate - Run UT - Impersonate - Access folder, and I'm not sure if this is the right design. Help would be greatly appreciated, thank you.

  • Problems compiling libjingle/gtk+-2.0 for Mac OS X

    - by mindthief
    Hi All, I'm trying to compile libjingle on Mac OSX Snow Leopard. The INSTALL file said to './configure', 'make' and 'make install', as usual. But make fails for me. Initially it gave some messages indicating that I didn't have pkg-config installed (I guess OSX doesn't come with it installed?), so I downloaded pkg-config from http://pkgconfig.freedesktop.org/releases/ Now I get this message: Package gtk+-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `gtk+-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'gtk+-2.0' found I tried to install gtk by using the script at SourceForge: http://sourceforge.net/projects/gtk-osx/ (this is the website pointed to by the gtk website) Running the script didn't really seem to do anything, here is the output: $./gtk-osx-build-setup.sh Checking out jhbuild (2.27.3) from git... From git://git.gnome.org/jhbuild * tag 2.27.3 -> FETCH_HEAD Installing jhbuild... Installing jhbuild configuration... Installing gtk-osx moduleset files... Done. $ And I still get that error message about "Package gtk+-2.0 not found" while make-ing libjingle. Help will be appreciated, thanks!

This was working fine, but it doesn't seem to able to match over multiple lines any more. For example the pattern 31 31 32 32 33 31 runs over multiple lines, and the regular expression doesn't seem to catch it. I tried using /m /s pattern modifiers to ignore new lines but they didn't match it either. The only way around it I can come up with, is to read the whole file into a string using: undef $/; my $whole_file = <FH>; my $line = $whole_file; $line =~ s/(00 00 00 64)/<incr4> /g; $line =~ s/(00 00 00 65)/<incr4> /g; $line =~ s/(30 30 30 30 30 32)/<incr6ascii:999999:0>/g; $line =~ s/(31 31 32 32 33 31)/<incr6ascii:999999:0>/g; print OUTPUT $line; This works, the tags get inserted correctly, but the structure of the file is radically altered. It is all dumped out on a single line. I would like to retain the structure of the file as it appears here. Any ideas as to how I might do this? /john

  • how do I get eclipse to use a different compiler version for Java?

    - by codeman73
    It seems like this should be a simple task, with the options in the Preferences menu for different JREs and the ability to set different compiler and build paths per project. However, it also seems to simply not work. For example, I have my JAVA_HOME set to a jre for Java 1.6. It's still not clear to me how Eclipse uses this, but it appears to be defaulting to this and not taking the project overrides. I have also installed Java 1.5, and added a JRE for this in eclipse in the Java-Installed JREs section. In my project, I've set the compiler compliance level to 1.5. In the build path for the project, I've added the System Library for the Java 1.5 JRE. However, I'm getting compile errors for a class that implements PreparedStatement for not implementing abstract methods that only exist in Java 1.6 PreparedStatement. Specifically, the methods setAsciiStream(int, InputStream, long) and setAsciiStream(int, InputStream) Strangely enough, it worked when we were compiling it against Java 1.4, which it was originally written for. We added the JREs for Java 1.4 and referenced that system library in the project, and set the project's compiler level to 1.4, and it works fine. But when I do the same changes to try to point to Java 1.5, it instead uses 1.6. Any ideas why?

  • XCode can't find headers in /usr/include

    - by mindthief
    Hi all, I'm trying to use standard system header files in my C++ XCode project: #include <openssl/bio.h> #include <openssl/ssl.h> #include <openssl/err.h> The build fails and it complains: "Openssl/bio.h: No such file or directory" I added /usr/include to the "Header Search Paths" in Project settings, but that doesn't fix it. I COULD fix it by adding the whole path like: #include </usr/include/openssl/bio.h> -- but the project is full of similar includes and I don't want to change all of them this way. Also, I feel I shouldn't have to do this. Another way to fix it would be as another thread mentioned, which is to add /usr/include to User Header Search Paths. But if I do that, then I'd have to change all the angle brackets < to quotes "", which again seems like a hack. I mean, these are standard system header files so I feel it should be something simple, not requiring these kinds of hacks. Any ideas? Thanks!

  • How to create databinding over two xaml files?

    - by BionicGecko
    Hello, I am trying to come to a working understanding of how databinding works, but even after several tutorials I only have a basic understanding of how databinding works. Thus this question might seem fundamental to those more familiar with silverlight. Even if it is trivial, please point me to some tutorial that deals with this problem. All that I could find simply solved this via adding the data binding on a parent page.xaml (that i must not use in my case). For the sake of this example let us assume, that we have 5 files: starter.cs button1.xaml + codeBehind button2.xaml + codeBehind The two buttons are generated in code in the starter(.cs) file, and then added to some MapLayer button1 my_button1 = new button1(); button2 my_button1 = new button2(); someLayer.Children.Add(my_button1); someLayer.Children.Add(my_button2); My aim is to connect the two buttons, so that they always display the same "text" (i.e. my_button1.content==my_button2.content = true;). Thus when something changes my_button1.content this change should be propagated to the other button (two way binding). At the moment my button1.xaml looks like this: <Grid x:Name="LayoutRoot"> <Button x:Name="x_button1" Margin="0,0,0,0" Content="{Binding ElementName=x_button2, Path=Content}" ClickMode="Press" Click="button1_Click"/> </Grid> But everthing that i get out of that is a button with no content at all, it is just blank as the binding silently fails. How could I create the databinding in the context I described? Preferably in code and not XAML ;) Thanks in advance

  • Access/Download server files, not in site root, with PHP

    - by user271619
    Usually I save documents (images, mpegs, excel, word docs, etc...) for my friends or family on my website's root, inside a directory called /files/ or something similar. Nothing too uncommon. But, I have been playing with user session control, and allowing users to upload files to the dedicated /files/ directory. (the file names are saved in a db, with that user's ID) But, that means other people could try to guess and locate other people's files. I do randomize the file names, upon upload. And I stop the apache from displaying the /files/ directory content. However, I'd like to start saving the files outside of the website's root. This way it can't be accessible via the browser. I don't have any code to show, but I didn't want to even start on this endeavor if it's not able to be accomplished. I did find this snippet that shows how to display an image, from outside your website root: $file = $_GET['file']; $fileDir = '/path/to/files/'; if (file_exists($fileDir . $file)) { // Note: You should probably do some more checks // on the filetype, size, etc. $contents = file_get_contents($fileDir . $file); // Note: You should probably implement some kind // of check on filetype header('Content-type: image/jpeg'); echo $contents; } ? Maybe I can use this for any file type, but has anyone heard of a better way to allow users (logged in) to access their files from online, but not letting other users has similar access?

  • Running Solr on VPS problems

    - by Camran
    I have a VPS with Ubuntu OS. I run solr om my local machine (windows xp laptop) just fine. I have configured Jetty, and Solr just the same way as on my computer, but on the server. I have also downloaded the JRE and installed it on the server. However, whenever I try to run the start.jar file, the PuTTY terminal shows a bunch of text but gets stuck. I could pase the text here but it is very long, so unless somebody wants to see it I wont. Also, I cant view the solr admin page at all. Does anybody have experience in this kind of problem? Maybe java isn't correctly installed? It is a VPS so maybe installation is different. Thanks UPDATE: These are the last lines from the terminal, in other words, this is where it stops every time: INFO: [] webapp=null path=null params={event=firstSearcher&q=static+firstSearcher+warming+query+from+solrconfig.xml} hits=0 status=0 QTime=9 May 28, 2010 8:58:42 PM org.apache.solr.core.QuerySenderListener newSearcher INFO: QuerySenderListener done.

  • trying to read a delimited text file from resources - but it wont run

  • I'm looking for this graph solution

  • Python: How can I use Twisted as the transport for SUDS?

    - by jathanism
    I have a project that is based on Twisted used to communicate with network devices and I am adding support for a new vendor (Citrix NetScaler) whose API is SOAP. Unfortunately the support for SOAP in Twisted still relies on SOAPpy, which is badly out of date. In fact as of this question (I just checked), twisted.web.soap itself hasn't even been updated in 21 months! I would like to ask if anyone has any experience they would be willing to share with utilizing Twisted's superb asynchronous transport functionality with SUDS. It seems like plugging in a custom Twisted transport would be a natural fit in SUDS' Client.options.transport, I'm just having a hard time wrapping my head around it. I did come up with a way to call the SOAP method with SUDS asynchronously by utilizing twisted.internet.threads.deferToThread(), but this feels like a hack to me. Here is an example of what I've done, to give you an idea: # netscaler is a module I wrote using suds to interface with NetScaler SOAP # Source: http://bitbucket.org/jathanism/netscaler-api/src import netscaler import os import sys from twisted.internet import reactor, defer, threads # netscaler.API is the class that sets up the suds.client.Client object host = 'netscaler.local' username = password = 'nsroot' wsdl_url = 'file://' + os.path.join(os.getcwd(), 'NSUserAdmin.wsdl') api = netscaler.API(host, username=username, password=password, wsdl_url=wsdl_url) results = [] errors = [] def handleResult(result): print '\tgot result: %s' % (result,) results.append(result) def handleError(err): sys.stderr.write('\tgot failure: %s' % (err,)) errors.append(err) # this converts the api.login() call to a Twisted thread. # api.login() should return True and is is equivalent to: # api.service.login(username=self.username, password=self.password) deferred = threads.deferToThread(api.login) deferred.addCallbacks(handleResult, handleError) reactor.run() This works as expected and defers return of the api.login() call until it is complete, instead of blocking. But as I said, it doesn't feel right. Thanks in advance for any help, guidance, feedback, criticism, insults, or total solutions.

  • C# app running as either Windows Form or as Console Application

    - by Aeolien
    I am looking to have one of my Windows Forms applications be run programmatically—from the command line. In preparation, I have separated the logic in its own class from the Form. Now I am stuck trying to get the application to switch back and forth based on the presence of command line arguments. Here is the code for the main class: static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { string[] args = Environment.GetCommandLineArgs(); if (args.Length > 1) // gets passed its path, by default { CommandLineWork(args); return; } Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } private static void CommandLineWork(string[] args) { Console.WriteLine("It works!"); Console.ReadLine(); } where Form1 is my form and the It works! string is just a placeholder for the actual logic. Right now, when running this from within Visual Studio (with command line arguments), the phrase It works! is printed to the Output. However, when running the /bin/Debug/Program.exe file (or /Release for that matter) the application crashes. Am I going about this the right way? Would it make more sense (i.e. take less developer time) to have my logic class be a DLL that gets loaded by two separate applications? Or is there something entirely different that I'm not aware of? Thanks in advance!

  • Best way to store and deliver files on a CMS

    - by Tio
    Hi all.. First of all, this isn't another question about storing images on DB vs file system. I'm already storing the images on the file system. I'm just struggling to find a better way to show them to all my users. I' currently using this system. I generate a random filename using md5(uniqueid()), the problem that I'm facing, is that the image is then presented with a link like this: <img src="/_Media/0027a0af636c57b75472b224d432c09c.jpg" /> As you can see this isn't the prettiest way to show a image ( or a file ), and the name doesn't say anything about the image. I've been working with a CMS system at work, that stores all uploaded files on a single table, to access that image it uses something like this: <img src="../getattachment/94173104-e03c-499b-b41c-b25ae05a8ee1/Menu-1/Escritorios.aspx?width=175&height=175" /> As you can see the path to the image, now has a meaning compared to the other one, the problem is that this put's a big strain in the DB, for example, in the last site I made, I have an area that has around 60 images, to show the 60 images, I would have to do at least 60 individual query's to the database, besides the other query's to retrieve the various content on the page. I think you understand my dilemma, has anyone gone trough this problem, that can give me some pointers on how to solve this? Thanks..

  • Execute function without sending 'self' to it

    - by Sergey
    Is that possible to define a function without referencing to self this way? def myfunc(var_a,var_b) But so that it could also get sender data, like if I defined it like this: def myfunc(self, var_a,var_b) That self is always the same so it looks a little redundant here always to run a function this way: myfunc(self,'data_a','data_b'). Then I would like to get its data in the function like this sender.fields. UPDATE: Here is some code to understand better what I mean. The class below is used to show a page based on Jinja2 templates engine for users to sign up. class SignupHandler(webapp.RequestHandler): def get(self, *args, **kwargs): utils.render_template(self, 'signup.html') And this code below is a render_template that I created as wrapper to Jinja2 functions to use it more conveniently in my project: def render_template(response, template_name, vars=dict(), is_string=False): template_dirs = [os.path.join(root(), 'templates')] logging.info(template_dirs[0]) env = Environment(loader=FileSystemLoader(template_dirs)) try: template = env.get_template(template_name) except TemplateNotFound: raise TemplateNotFound(template_name) content = template.render(vars) if is_string: return content else: response.response.out.write(content) As I use this function render_template very often in my project and usually the same way, just with different template files, I wondered if there was a way to get rid of having to call it like I do it now, with self as the first argument but still having access to that object.

  • maven and unit testing - combining maven surefire plugin AND testNG eclipse plugin

    - by lisak
    Hey, could you please share your way of unit testing in eclipse ? Are you using surefire plugin, m2eclipse & maven, or only testNG eclipse plugin ? Do you combine these alternatives ? I'm using testNG + maven surefire-plugin and I had been using the testNG eclipse plugin a year ago so that I could see the results in testNG view. Then I started using Maven, but when I do "maven test phase" using m2eclipse, there is only console output and surefire reports that I can check in browser and to choose what test suite, test, or test method can be set up only via testng.xml. On the other hand, if you use only surefire plugin and you have some specific settings regarding classpath etc., that you rely on, then running tests via testNG eclipse plugin doesn't have to be compatible with your code. Using surefire plugin, the classpath is different - target/test-classes and target/classes - than using testNG plugin, that is using the project classpath. How do you go about what I was just talking about? Is it possible to synchronize "maven test" using m2eclipse and surefire plugin WITH testNG eclipse plugin and view ? EDITED: I'm also wondering, why the Maven project ("Java build path") output folder is target/classes for src/main and src/test whereas surefire plugin makes two locations target/test-classes and target/classes Thank you very much for your your opinions.

  • WPF-Can a XAML object be a source as well as a target for bindings?

    - by iambic77
    I was wondering if it's possible to have a TextBlock as a target and a source? Basically I have a bunch of entities which have simple relationships to other entities (like Entity1 Knows Entity3, Entity3 WorksAt Entity2 etc.) I have a Link class that stores SourceEntity, Relationship and TargetEntity details. What I want to be able to do is to select an entity then display the relationships related to that entity, with the target entities of each relationship listed underneath the relationship names. When an entity is selected, an ObservableCollection is populated with the Links for that particular entity (SelectedEntityLinks<Link>). Because each entity could have the same relationship to more than one target entity (Entity1 could know both Entity3 and Entity4 for eg.), I've created a method GetThisRelationshipEntities() that takes a relationship name as a parameter, looks through SelectedEntityLinks for relationship names that match the parameter, and returns an ObservableCollection with the target entities of that relationship. Hope I'm making this clear. In my xaml I have a WrapPanel to display each relationship name in a TextBlock: <TextBlock x:Name="relationship" Text="{Binding Path=Relationship.Name}" /> Then underneath that another Textblock which should display the results of GetThisRelationshipEntities(String relationshipName). So I want the "relationship" TextBlock to both get its Text from the binding I've shown above, but also to provide its Text as a parameter to the GetThisRelationshipEntities() method which I've added to <UserControl.Resources> as an ObjectDataProvider. Sorry if this is a bit wordy but I hope it's clear. Any pointers/advice would be great. Many thanks.

  • Readonly SiteMapNodes in ASP.Net MVC?

    - by BenN
    I'm using MVCSiteMap as a SiteMapProvider for my MVC site. I have a node set up like so.... <mvcSiteMapNode key="1" title="Product" controller="Product" action="Display" isDynamic="true" dynamicParameters="id"> <mvcSiteMapNode key="11" title="More Details" controller="Product" action="MoreDetails" isDynamic="true" dynamicParameters="id" /> </mvcSiteMapNode> ...Which means I can go to ~/Product/Display/12 and get a correct sitemap node for product id 12 (in this case just Product. And I can go to ~/Product/MoreDetails/12 and get the sitemap path for the MoreDetails (Product - More Details). The problem is that the link back to Product in this sitemap doesn't work - it skips the id off the end, instead linking to ~/Product/Display/. Which sucks. I've discovered I can edit the Title of a node using SiteMap.CurrentNode.Title = "My New Title"; But... SiteMap.CurrentNode.ParentNode.Url = "http://www.google.com"; Doesn't set the Url for the parent node; it gets the default link described before. Any ideas how I can set the URL of a SiteMapNode?

  • Java XML Output - proper indenting for child items

    - by Dr1Ku
    Hello, I'd like to serialize some simple data model into xml, I've been using the standard java.org.w3c -related code (see below), the indentation is better than no "OutputKeys.INDENT", yet there is one little thing that remains - proper indentation for child elements. I know that this has been asked before on stackoverflow , yet that configuration did not work for me, this is the code I'm using : DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = factory.newDocumentBuilder(); Document doc = builder.newDocument(); doc = addItemsToDocument(doc); // The addItemsToDocument method adds childElements to the document. TransformerFactory transformerFactory = TransformerFactory.newInstance(); transformerFactory.setAttribute("indent-number", new Integer(4)); // switching to setAttribute("indent-number", 4); doesn't help Transformer transformer = transformerFactory.newTransformer(); transformer.setOutputProperty(OutputKeys.METHOD, "xml"); transformer.setOutputProperty(OutputKeys.INDENT, "yes"); DOMSource source = new DOMSource(doc); StreamResult result = new StreamResult(outFile); // outFile is a regular File outFile = new File("some/path/foo.xml"); transformer.transform(source, result); The output produced is : <?xml version="1.0" encoding="UTF-8" standalone="no"?> <stuffcontainer> <stuff description="something" duration="240" title="abc"> <otherstuff /> </stuff> </stuffcontainer> Whereas I would want it (for more clarity) like : <?xml version="1.0" encoding="UTF-8" standalone="no"?> <stuffcontainer> <stuff description="something" duration="240" title="abc"> <otherstuff /> </stuff> </stuffcontainer> I was just wondering if there is a way of doing this, make it properly indented for the child elements. Thank you in advance ! Happy Easter coding :-) !

  • Why does Perl's DBI complain about "failed: ERROR OCIEnvNlsCreate" when I try to connect to Oracle 1

    - by John
    I am getting the following error connecting to an Oracle 11g database using a simple Perl script: failed: ERROR OCIEnvNlsCreate. Check ORACLE_HOME (Linux) env var or PATH (Windows) and or NLS settings, permissions, etc. at The script is as follows: #!/usr/local/bin/perl use strict; use DBI; if ($#ARGV < 3) { print "Usage: perl testDbAccess.pl dataBaseUser dataBasePassword SID dataBasePort\n"; exit 0; } my ($user, $pwd, $sid, $port) = @ARGV; my $host = `hostname`; my $dbh; my $sth; my $dbname = "dbi:Oracle:HOST=$host;SID=$sid;PORT=$port"; openDbConnection(); closeDbConnection(); sub openDbConnection() { $dbh = DBI->connect ($dbname, $user ,$pwd , { RaiseError => 1}) || die "Database connection not made: $DBI::errstr"; } sub closeDbConnection() { #$sth->finish(); $dbh->disconnect(); } Anyone seen this problem before?

  • Save PyML.classifiers.multi.OneAgainstRest(SVM()) object?

    - by Michael Aaron Safyan
    I'm using PYML to construct a multiclass linear support vector machine (SVM). After training the SVM, I would like to be able to save the classifier, so that on subsequent runs I can use the classifier right away without retraining. Unfortunately, the .save() function is not implemented for that classifier, and attempting to pickle it (both with standard pickle and cPickle) yield the following error message: pickle.PicklingError: Can't pickle : it's not found as __builtin__.PySwigObject Does anyone know of a way around this or of an alternative library without this problem? Thanks. Edit/Update I am now training and attempting to save the classifier with the following code: mc = multi.OneAgainstRest(SVM()); mc.train(dataset_pyml,saveSpace=False); for i, classifier in enumerate(mc.classifiers): filename=os.path.join(prefix,labels[i]+".svm"); classifier.save(filename); Notice that I am now saving with the PyML save mechanism rather than with pickling, and that I have passed "saveSpace=False" to the training function. However, I am still gettting an error: ValueError: in order to save a dataset you need to train as: s.train(data, saveSpace = False) However, I am passing saveSpace=False... so, how do I save the classifier(s)? P.S. The project I am using this in is pyimgattr, in case you would like a complete testable example... the program is run with "./pyimgattr.py train"... that will get you this error. Also, a note on version information: [michaelsafyan@codemage /Volumes/Storage/classes/cse559/pyimgattr]$ python Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. import PyML print PyML.__version__ 0.7.0

  • Can I force Apache 2.2 connection close from inside a C module?

    - by Amos Shapira
    Hello, We'd like to have a more fine-grained control on the connections we serve in a C++ Apache 2.2 module (on CentOS 5). One of the connections needs to stay alive for a few multiple requests, so we set "KeepAlive" to "On" and set a short keep-alive period. But for every such connection we have a few more connections from the browser which we don't need to leave behind and instead want to force them to close after a single request. Some of these connections are on different ports (so we can distinguish them by port, since KeepAlive can be set per virtual host) and some request a different URL (so we can tell from the path and parameters that we don't want to leave them behind). Also for the one we do want to keep alive, we know that after a certain request we'd like to close it too. But so far the only way we found to "cancel" the keep-alive is to send a polite "Connection: close" header to the client. If the client is not well behaved, or malicious, then they can keep it open and waste our resources. Is there a way to tell Apache to close the connection from the server side? The documentation advises against just plain close(2) call on the socket since Apache needs to do some clean up before that's done. But is there some API or a trick to "override" the static "KeepAlive On" configuration dynamically (and convince Apache to call close(2))? Thanks.
