• UNIX-style RegExp Replace running extremely slowly under windows. Help? EDIT: Negative lookahead ass

  - by John Sullivan

  I'm trying to run a unix regEXP on every log file in a 1.12 GB directory, then replace the matched pattern with ''. Test run on a 4 meg file is took about 10 minutes, but worked. Obviously something is murdering performance by several orders of magnitude. Find: ^(?!.*155[0-2][0-9]{4}\s.*).*$ -- NOTE: match any line NOT starting 155[0-2]NNNN where in is a number 0-9. Replace with: ''. Is there some justifiable reason for my regExp to take this long to replace matching text, or is the program I am using (this is windows / a program called "grepWin") most likely poorly optimized? Thanks. UPDATE: I am noticing that searching for ^(155[0-2]).$ takes ~7 seconds in a 5.6 MB file with 77 matches. Adding the Negative Lookahead Assertion, ?=, so that the regExp becomes ^(?!155[0-2]).$ is causing it to take at least 5-10 minutes; granted, there will be thousands and thousands of matches. Should the negative lookahead assertion be extremely detrimental to performance, and/or a large quantity of matches?

• Uncompress a TIFF file without going through BufferedImage

  - by Gert

  I am receiving large size CCITT Group 4 compressed TIFF files that need to be written elsewhere as uncompressed TIFF files. I am using the jai_imageio TIFF reader and writer to do that and it works well as long as the product _width * height_ of the image fits in an integer. Here is the code I am using: TIFFImageReaderSpi readerSpi= new TIFFImageReaderSpi(); ImageReader imageReader = readerSpi.createReaderInstance(); byte[] data = blobManager.getObjectForIdAndVersion(id, version); ImageInputStream imageInputStream = ImageIO.createImageInputStream(data); imageReader.setInput(imageInputStream); TIFFImageWriterSpi writerSpi = new TIFFImageWriterSpi(); ImageWriter imageWriter = writerSpi.createWriterInstance(); ImageWriteParam imageWriteParam = imageWriter.getDefaultWriteParam(); imageWriteParam.setCompressionMode(ImageWriteParam.MODE_DISABLED); //bufferFile is created in the constructor ImageOutputStream imageOutputStream = ImageIO.createImageOutputStream(bufferFile); imageWriter.setOutput(imageOutputStream); //Now read the bitmap BufferedImage bufferedImage = imageReader.read(0); IIOImage iIOImage = new IIOImage(bufferedImage, null, null); //and write it imageWriter.write(null, iIOImage, imageWriteParam); Unfortunately, the files that I receive are often very large and the BufferedImage cannot be created. I have been trying to find a way to stream from the ImageReader directly to the ImageWriter but I cannot find out how to do that. Anybody with a suggestion?

• DesignTime data not showing in Blend when bound against CollectionViewSource

  - by bitbonk

  I have datatemplate for a viewmodel where an itemscontrol is bound again a CollectionViewSource (to enable sorting in xaml). <DataTemplate x:Key="equipmentDataTemplate"> <Viewbox> <Viewbox.Resources> <CollectionViewSource x:Key="viewSource" Source="{Binding Modules}"> <CollectionViewSource.SortDescriptions> <scm:SortDescription PropertyName="ID" Direction="Ascending"/> </CollectionViewSource.SortDescriptions> </CollectionViewSource> </Viewbox.Resources> <ItemsControl ItemsSource="{Binding Source={StaticResource viewSource}}" Height="{DynamicResource equipmentHeight}" ItemTemplate="{StaticResource moduleDataTemplate}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal" /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </Viewbox> </DataTemplate> I have also setup the UserControl where all of this is defined to provide designtime data d:DataContext="{x:Static vm:DesignTimeHelper.Equipment}"> This is basically a static property that gives me an EquipmentViewModel that has a list of ModuleViewModels (Equipment.Modules). Now as long as I bind to the CollectionViewSource the designtime data does not show up in blend 3. When I bind to the ViewModel collection directly <ItemsControl ItemsSource="{Binding Modules}" I can see the designtime data. Any idea what I could do?

• How to access SQL CE 3.5 from VB6

  - by Masterfu

  We have a .NET 3.5 SP1 application written in C# that stores data in an SQL CE 3.5 Database. We also need to access (read only) this very data from a legacy VB6 application. I don't know if this is at all possible. There are several approaches to this problem that I can think of. 1) I have read about ADOCE Connections, but this seems to be an option for embedded Visual Basic only 2) I can't seem to get a connection working using ADODB.Connection Objects like so Dim MyConnObj As New ADODB.Connection ' Microsoft.SQLSERVER.CE.OLEDB.3.5 ' Microsoft.SQLSERVER.MOBILE.OLEDB.3.0 MyConnObj.ConnectionString = "Provider=SQLOLEDB;Data Source=c:\test.sdf" MyConnObj.Open Maybe this is just a bad choice of providers? I also tried the providers that appear as comments above and different connection strings, but to no avail. Both providers are not installed on my dev machine and won't be installed on my customer's machine. 3) Maybe there is a way to use a more generic approach like ODBC? But I believe this would result in setup / deployment work, right? Does anyone have any experience with this scenario? As you can see, I am really looking for some good starting points. I also accept answers like "This is drop dead simple and so are you" as long as they come with some guiding directions ;-)

• What header file is where the boost libray define its own primitive data type?

  - by ronghai

  Recently, I try to use the boost::spirit::qi binary endian parser to parse some binary data depends on the endianness of the Platform. There is a simple example, like following: Using declarations and variables: using boost::spirit::qi::little_word; using boost::spirit::qi::little_dword; using boost::spirit::qi::little_qword; boost::uint16_t us; boost::uint32_t ui; boost::uint64_t ul; Basic usage of the little endian binary parsers: test_parser_attr("\x01\x02", little_word, us); assert(us == 0x0201); test_parser_attr("\x01\x02\x03\x04", little_dword, ui); assert(ui == 0x04030201); test_parser_attr("\x01\x02\x03\x04\x05\x06\x07\x08", little_qword, ul); assert(ul == 0x0807060504030201LL); test_parser("\x01\x02", little_word(0x0201)); test_parser("\x01\x02\x03\x04", little_dword(0x04030201)); test_parser("\x01\x02\x03\x04\x05\x06\x07\x08", little_qword(0x0807060504030201LL)); It works very well. But my questions come, why do we need use some data types like boost::uint16_t, boost::uint32_t here? Can I use unsigned long or unsigned int here? And if I want to parse double or float data type, what boost data type should I use? And please tell me where is boost define the above these types? Thanks a lot.

• how to make a column width size fixed in datagridview asp?

  - by user306671

  Hi, i have this column in a datagridview on aspx page <asp:TemplateField HeaderText="Observacion"> <ItemTemplate> <asp:Label ID="lblOrderID" runat="server" Text='<%# Eval("Observacion") %>'></asp:Label> </ItemTemplate> <ItemStyle Width="200px" Wrap="False" /> </asp:TemplateField> I have set up the itemstyle with and wrap to false, but anyways the width columns grows the the data is too long. i just want to change the height of the column not the width. Here us the complete code of the datagridview <asp:GridView ID="GridView1" runat="server" AutoGenerateDeleteButton="True" CellPadding="4" EnableModelValidation="True" ForeColor="#333333" GridLines="None" AutoGenerateColumns="False"> <columns> <asp:boundfield datafield="ID_OBSERVACION" visible="False" /> <asp:boundfield datafield="AUTOR" headertext="Autor" /> <asp:boundfield datafield="FECHA" headertext="Fecha" /> <asp:TemplateField HeaderText="Observacion"> <ItemTemplate> <asp:Label ID="lblOrderID" runat="server" Text='<%# Eval("Observacion") %>'></asp:Label> </ItemTemplate> <ItemStyle Width="200px" Wrap="False" /> </asp:TemplateField> </columns> <AlternatingRowStyle BackColor="White" ForeColor="#284775" Wrap="False" /> <EditRowStyle BackColor="#999999" /> <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" /> <RowStyle BackColor="#F7F6F3" ForeColor="#333333" Wrap="False" /> <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" /> </asp:GridView>

• categorize a set of phrases into a set of similar phrases

  - by Dingo

  I have a few apps that generate textual tracing information (logs) to log files. The tracing information is the typical printf() style - i.e. there are a lot of log entries that are similar (same format argument to printf), but differ where the format string had parameters. What would be an algorithm (url, books, articles, ...) that will allow me to analyze the log entries and categorize them into several bins/containers, where each bin has one associated format? Essentially, what I would like is to transform the raw log entries into (formatA, arg0 ... argN) instances, where formatA is shared among many log entries. The formatA does not have to be the exact format used to generate the entry (even more so if this makes the algo simpler). Most of the literature and web-info I found deals with exact matching, a max substring matching, or a k-difference (with k known/fixed ahead of time). Also, it focuses on matching a pair of (long) strings, or a single bin output (one match among all input). My case is somewhat different, since I have to discover what represents a (good-enough) match (generally a sequence of discontinuous strings), and then categorize each input entries to one of the discovered matches. Lastly, I'm not looking for a perfect algorithm, but something simple/easy to maintain. Thanks!

• Using a UITableViewController with a small-sized table?

  - by rpj

  When using a UITableViewController, the initWithStyle: method automatically creates the underlying UITableView with - according to the documentation - "the correct dimensions". My problem is that these "correct dimensions" seem 320x460 (the iPhone's screen size), but I'm pushing this TableView/Controller pair into a UINavigationController which is itself contained in a UIView, which itself is about half the height of the screen. No frame or bounds wrangling I can come up with seems to correctly reset the table's size, and as such it's "too long", meaning there are a collection of rows that are pushed off the bottom of the screen and are not visible nor reachable by scrolling. So my question comes down to: what is the proper way to tell a UITableViewController to resize its component UITableView to a specified rectangle? Thanks! Update I've tried all the techniques suggested here to no avail, but I did find one interesting thing: if I eschew the UINavigationController altogether (which I'm not yet willing to do for production, but as an experiment), and add the table view as a direct subview of the enclosing view I mentioned, the frame size given is respected. The very moment I re-introduce the UINavigationController into the mix, no matter if it is added as a subview before or after the table view, and no matter if alloc/init it before or after the table view is added as a subview, the result is the same as it was before. I'm beginning to suspect UINavigationController isn't much of a team player... Update 2 The suggestion to check frame size after the table view on screen was a good one: turns out that the navigation controller is in fact resizing it some time in between load and display. My solution, hacky at best, has been to cache the frame given on load and to reset it if changed at the beginning of tableView:cellForRowAtIndexPath:. Why there you ask? Because it's the one place I found that worked, that's why! I don't consider this a solution as it's obviously improper, but for the benefit of anyone else reading, it does seem to work.

• [hibernate - jpa] @CollectionOfElements without create the apposite table

  - by blow

  Hi all. I have this: Municipality class @Entity public class Municipality implements Serializable { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id; private String country; private String province; private String name; @Column(name="cod_catasto") private String codCatastale; private String cap; @CollectionOfElements private List<Address> addressList; public Municipality() { } ... Address class @Embeddable public class Address implements Serializable { @ManyToOne(fetch=FetchType.LAZY) @Cascade(CascadeType.SAVE_UPDATE) private Municipality municipality; @Column(length=45) private String address; public Address() { } ... Address is embedded in another class Person. When i save an instance of Person, hibernate create 3 tables: PERSON, MUNICIPALITY and MUNICIPALITY_ADDRESSLIST. MUNICIPALITY_ADDRESSLIST contains 2 fields: MUNICIPALITY_ID (FK) and STREET. I don't want this table, i only want the ID of table MUNICIPALITY into table PERSON(that embeds Address), what should i do? I tried to add @JoinTable in Municipality entity like this: @CollectionOfElements @JoinTable(name="person") private List<Address> addressList; It partially worked, but i cant choose the column name of table PERSON that contains ID of the table MUNICIPALITY, it is, by hibernate choose, simply "MUNICIPALITY_ID"... Thbaks.

• Memory usage in Flash / Flex / AS3

  - by ggambett

  I'm having some trouble with memory management in a flash app. Memory usage grows quite a bit, and I've tracked it down to the way I load assets. I embed several raster images in a class Embedded, like this [Embed(source="/home/gabriel/text_hard.jpg")] public static var ASSET_text_hard_DOT_jpg : Class; I then instance the assets this way var pClass : Class = Embedded[sResource] as Class; return new pClass() as Bitmap; At this point, memory usage goes up, which is perfectly normal. However, nulling all the references to the object doesn't free the memory. Based on this behavior, looks like the flash player is creating an instance of the class the first time I request it, but never ever releases it - not without references, calling System.gc(), doing the double LocalConnection trick, or calling dispose() on the BitmapData objects. Of course, this is very undesirable - memory usage would grow until everything in the SWFs is instanced, regardless of whether I stopped using some asset long ago. Is my analysis correct? Can anything be done to fix this?

• Properties vs. Fields: Need help grasping the uses of Properties over Fields.

  - by pghtech

  First off, I have read through a list of postings on this topic and I don't feel I have grasped properties because of what I had come to understand about encapsulation and field modifiers (private, public..ect). One of the main aspects of C# that I have come to learn is the importance of data protection within your code by the use of encapsulation. I 'thought' I understood that to be because of the ability of the use of the modifiers (private, public, internal, protected). However, after learning about properties I am sort of torn in understanding not only properties uses, but the overall importance/ability of data protection (what I understood as encapsulation) within C#. To be more specific, everything I have read when I got to properties in C# is that you should try to use them in place of fields when you can because of: 1) they allow you to change the data type when you can't when directly accessing the field directly. 2) they add a level of protection to data access However, from what I 'thought' I had come to know about the use of field modifiers did #2, it seemed to me that properties just generated additional code unless you had some reason to change the type (#1) - because you are (more or less) creating hidden methods to access fields as opposed to directly. Then there is the whole modifiers being able to be added to Properties which further complicates my understanding for the need of properties to access data. I have read a number of chapters from different writers on "properties" and none have really explained a good understanding of properties vs. fields vs. encapsulation (and good programming methods). Can someone explain: 1) why I would want to use properties instead of fields (especially when it appears I am just adding additional code 2) any tips on recognizing the use of properties and not seeing them as simply methods (with the exception of the get;set being apparent) when tracing other peoples code? 3) Any general rules of thumb when it comes to good programming methods in relation to when to use what? Thanks and sorry for the long post - I didn't want to just ask a question that has been asked 100x without explaining why I am asking it again.

• Commit is VERY slow in my NHibernate / SQLite project

  - by Tom Bushell

  I've just started doing some real-world performance testing on my Fluent NHibernate / SQLite project, and am experiencing some serious delays when when I Commit to the database. By serious, I mean taking 20 - 30 seconds to Commit 30 K of data! This delay seems to get worse as the database grows. When the SQLite DB file is empty, commits happen almost instantly, but when it grows to 10 Meg, I see these huge delays. The database has 16 tables, averaging 10 columns each. One possible problem is that I'm storing a dozen or so IList members, but they are typically only 200 elements long. But this is a recent addition to Fluent NHibernate automapping, which stores each float in a single table row, so maybe that's a potential problem. Any suggestions on how to track this down? I suspect SQLite is the culprit, but maybe it's NHibernate? I don't have any experience with profilers, but am thinking of getting one. I'm aware of NHibernate Profiler - any recommendations for profilers that work well with SQLite? Here's the method that saves the data - it's just a SaveOrUpdate call and a Commit, if you ignore all the error handling and debug logging. public static void SaveMeasurement(object measurement) { Debug.WriteLine("\r\n---SaveMeasurement---"); // Get the application's database session var session = GetSession(); using (var transaction = session.BeginTransaction()) { try { session.SaveOrUpdate(measurement); } catch (Exception e) { throw new ApplicationException( "\r\n SaveMeasurement->SaveOrUpdate failed\r\n\r\n", e); } try { Debug.WriteLine("\r\n---Commit---"); transaction.Commit(); Debug.WriteLine("\r\n---Commit Complete---"); } catch (Exception e) { throw new ApplicationException( "\r\n SaveMeasurement->Commit failed\r\n\r\n", e); } } }

• Complete failure to compile when include CSS Friendly Adapters

  - by david

  Background - I am trying to use the friendly adapters to override the default styling for the standard asp.net menu control that is used by an existing project. The existing project functions normally and compiles when requested without incident. Adding in the code for the for the CSS Friendly adapter and not only does it not compile, but it never even really starts. The Problem in Detail - I am using the sample code from Scott on this page: http://weblogs.asp.net/scottgu/archive/2006/09/08/CSS-Control-Adapter-Toolkit-Update.aspx. The sample project compiles fine, just within the existing project does it fail. Fails without a line number or any other traceable info. It definately appears to be related to the CSSMenuAdapter.browser file, which has been referenced by others online as the cause of similar error. I have tried addind and readding, using as a dll, using as a code file in app code, etc. I am working with aspdotnetstorefront in this case, although it is not unique to them as I have found other references in software packages online. Only thing is, no one ever says what solved the issue. I am using Windows 7, VS2008 Express and SQL Express 2008 R2. The full error msg is: Error 10 Exception of type 'System.OutOfMemoryException' was thrown. Notice that there is no file, line, or column info. Really need some help here. I have been working on this a long time. This really should have tag: cssfriendlyadapter but I could not create that.

• When do you tag your software project?

  - by WilhelmTell of Purple-Magenta

  I realize there are various kinds of software projects: commercial (for John Doe) industrial (for Mr. Montgomery Burns) successful open-source (with audience larger than, say, 10 people) personal projects (with audience size in the vicinity of 1). each of which release a new version of their product on difference conditions. I'm particularly interested in the case of personal projects and open-source projects. When, or under what conditions, do you make a new release of any kind? Do you subscribe to a fixed recurring deadline such as every two weeks? Do you commit to a release of at least 10 minor fixes, or one major fix? Do you combine the two conditions such as at least one condition must hold, or both must hold? I reckon this is a subjective question. I ask this question in light of searching for tricks to keep my projects alive and kicking. Sometimes my projects are active but look as if they aren't because I don't have the confidence to make a release or a tag of any sort for a long time -- in the order of months.

• Get the signed/unsigned variant of an integer template parameter without explicit traits

  - by Blair Holloway

  I am looking to define a template class whose template parameter will always be an integer type. The class will contain two members, one of type T, and the other as the unsigned variant of type T -- i.e. if T == int, then T_Unsigned == unsigned int. My first instinct was to do this: template <typename T> class Range { typedef unsigned T T_Unsigned; // does not compile public: Range(T min, T_Unsigned range); private: T m_min; T_Unsigned m_range; }; But it doesn't work. I then thought about using partial template specialization, like so: template <typename T> struct UnsignedType {}; // deliberately empty template <> struct UnsignedType<int> { typedef unsigned int Type; }; template <typename T> class Range { typedef UnsignedType<T>::Type T_Unsigned; /* ... */ }; This works, so long as you partially specialize UnsignedType for every integer type. It's a little bit of additional copy-paste work (slash judicious use of macros), but serviceable. However, I'm now curious - is there another way of determining the signed-ness of an integer type, and/or using the unsigned variant of a type, without having to manually define a Traits class per-type? Or is this the only way to do it?

• Glassfish, railo and coldbox - messed up links?

  - by mrt181

  I am new to ColdFusion and ColdBox (and programming). I tried to setup ColdBox but some of the links in the sample applications are broken. My configuration is a GlassFish v3 installation with the current Railo OSS. I access my site through Apache 2.2.14. So instead of http://127.0.0.1:8080/railo/ I access my environment trough http://railo/. In Railo I have a webroot mapping / to C:/webapps/myproject/. I have copied the current ColdBox 3M4 to C:/webapps/myproject/coldbox. I can access the dashboard through http://railo/coldbox/dashboard/index.cfm and have access to all options. My problems start the moment I try to open the sample gallery: HTTP Status 500 - type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception java.io.FileNotFoundException: C:\webapps\viss-dev\coldbox\samples (Zugriff verweigert) note The full stack traces of the exception and its root causes are available in the GlassFish v3 logs. GlassFish v3 OK, no problem, just enter the link directly: http://railo/coldbox/samples/index.cfm. The site looks plain, who cares - BUT all local links look like this: http://127.0.0.1:8080/coldbox/samples/applications/helloworld/index.cfm (railo is replaced with 127.0.0.1:8080). Looks like trouble. To make my confusion perfect: when I try to access the login app: http://railo/coldbox/samples/applications/sampleloginapp/index.cfm and hit the submit button, I am redirected to this address: http://railo/railo/coldbox/samples/applications/sampleloginapp/index.cfm. I believe that this is not really ColdBox-related, but it manifests itself when I try to use ColdBox, so here I am. P.S.: amazon.de takes too long to ship the ColdBox book :(

• MVC: model of type Nullable<T>

  - by Fyodor Soikin

  I have a partial view that inherits from ViewUserControl<Guid?> - i.e. it's model is of type Nullable<Guid>. Very simple view, nothing special, but that's not the point. Somewhere else, I do Html.RenderPartial( "MyView", someGuid ), where someGuid is of type Nullable<Guid>. Everything's perfectly legal, should work OK, right? But here's the gotcha: the second argument of Html.RenderPartial is of type object, and therefore, Nullable<Guid> being a value type, it must be boxed. But nullable types are somehow special in the CLR, so that when you box one of those, you actually get either a boxed value of type T (Nullable's argument), or a null if the nullable didn't have a value to begin with. And that last case is actually interesting. Turns out, sometimes, I do have a situation when someGuid.HasValue == false. And in those cases, I effectively get a call Html.RenderPartial( "MyView", null ). And what does the HtmlHelper do when the model is null? Believe it or not, it just goes ahead and takes the parent view's model. Regardless of it's type. So, naturally, in those cases, I get an exception saying: "The model item passed into the dictionary is of type 'Parent.View.Model.Type', but this dictionary requires a model item of type 'System.Guid?'" So the question is: how do I make MVC correctly pass new Nullable<Guid> { HasValue = false } instead of trying to grab the parent's model? Note: I did consider wrapping my Guid? in an object of another type, specifically created for this occasion, but this seems completely ridiculous. Don't want to do that as long as there's another way. Note 2: now that I've wrote all this, I've realized that the question may be reduced to how to pass a null for model without ending up with parent's model?

  I want to better write this test: def test_profile_created(self): self.client.post(reverse('registration_register'), data={ 'username':'ygam', 'email':'[email protected]', 'password1':'ygam', 'password2':'ygam' }) """ Test if a profile is created on save """ user = User.objects.get(username='ygam') self.assertTrue(UserProfile.objects.filter(user=user).exists()) and I just came upon this code on django-registration tests that does not actually "create" the user: def test_registration_signal(self): def receiver(sender, **kwargs): self.failUnless('user' in kwargs) self.assertEqual(kwargs['user'].username, 'bob') self.failUnless('request' in kwargs) self.failUnless(isinstance(kwargs['request'], WSGIRequest)) received_signals.append(kwargs.get('signal')) received_signals = [] signals.user_registered.connect(receiver, sender=self.backend.__class__) self.backend.register(_mock_request(), username='bob', email='[email protected]', password1='secret') self.assertEqual(len(received_signals), 1) self.assertEqual(received_signals, [signals.user_registered]) However he used a custom function for this "_mock_request": class _MockRequestClient(Client): def request(self, **request): environ = { 'HTTP_COOKIE': self.cookies, 'PATH_INFO': '/', 'QUERY_STRING': '', 'REMOTE_ADDR': '127.0.0.1', 'REQUEST_METHOD': 'GET', 'SCRIPT_NAME': '', 'SERVER_NAME': 'testserver', 'SERVER_PORT': '80', 'SERVER_PROTOCOL': 'HTTP/1.1', 'wsgi.version': (1,0), 'wsgi.url_scheme': 'http', 'wsgi.errors': self.errors, 'wsgi.multiprocess':True, 'wsgi.multithread': False, 'wsgi.run_once': False, 'wsgi.input': None, } environ.update(self.defaults) environ.update(request) request = WSGIRequest(environ) # We have to manually add a session since we'll be bypassing # the middleware chain. session_middleware = SessionMiddleware() session_middleware.process_request(request) return request def _mock_request(): return _MockRequestClient().request() However, it may be too long of a function for my needs. I want to be able to somehow "fake" the account creation. I have not much experience on mocks and stubs so any help would do. Thanks!

• echo POST array.. or other ideas?

  - by gamerzfuse

  Update: As seen in the Original Questions below, I am looking to echo an array. The problem is that when I send the Moneris gateway to return a POST array to my new file (cart.php) it gets a 500 Internal Server Error. This is the same error I received when it send to the script, which should have worked. Is there any reason that it would always send a 500 Internal Server Error? Cart.php Direct Link Craig ORIGINAL QUESTION: Hello there, I am back for another question. Here is my dilemma: I have a script (ImageFolio Commerce) that hasn't been updated on our server since.. probably 2003. The script had a Payment Gateway (Moneris) manually added to it by the company who offers the script. This costs $1000 to get them to add a gateway. I now have a new client who purchased this business from the previous owner. While switching the account to the new owner's Moneris account, we found out that things have been updated. Long story short.. The Moneris gateway can send 3 types of responses: POST with XML Data POST GET I imagine it is easiest to just use the POST array. I have the file that it sends the response to. As of now the file responds with a Internal Server error, but it does process the order. What I want to do is determine what the POST array is that is being sent, so that I can take it and echo it in a logical manner. Is there a way to capture and echo the entire POST? Or can someone suggest a better method of doing this? Thank you, Craig

• Could Python's logging SMTP Handler be freezing my thread for 2 minutes?

  - by Oddthinking

  A rather confusing sequence of events happened, according to my log-file, and I am about to put a lot of the blame on the Python logger, which is a bold claim. I thought I should get some second opinions about whether what I am saying could be true. I am trying to explain why there is are several large gaps in my log file (around two minutes at a time) during stressful periods for my application when it is missing deadlines. I am using Python's logging module on a remote server, and have set-up, with a configuration file, for all logs of severity of ERROR or higher to be emailed to me. Typically, only one error will be sent at a time, but during periods of sustained problems, I might get a dozen in a minute - annoying, but nothing that should stress SMTP. I believe that, after a short spurt of such messages, the Python logging system (or perhaps the SMTP system it is sitting on) is encountering errors or congestion. The call to Python's log is then BLOCKING for two minutes, causing my thread to miss its deadlines. (I was smart enough to move the logging until after the critical path of the application - so I don't care if logging takes me a few seconds, but two minutes is far too long.) This seems like a rather awkward architecture (for both a logging system that can freeze up, and for an SMTP system (Ubuntu, sendmail) that cannot handle dozens of emails in a minute**), so this surprises me, but it exactly fits the symptoms. Has anyone had any experience with this? Can anyone describe how to stop it from blocking? ** EDIT: I actually counted. A little under 4000 short emails in two hours. So far more than I suggested, sorry. But enough to over-fill a Sendmail's buffers?

• How can I make an even more random number in ActionScript 2.0

  - by Theo

  I write a piece of software that runs inside banner ads which generates millions of session IDs every day. For a long time I've known that the random number generator in Flash is't random enough to generate sufficiently unique IDs, so I've employed a number of tricks to get even more random numbers. However, in ActionScript 2.0 it's not easy, and I'm seeing more and more collisions, so I wonder if there is something I've overlooked. As far as I can tell the problem with Math.random() is that it's seeded by the system time, and when you have sufficient numbers of simultaneous attempts you're bound to see collisions. In ActionScript 3.0 I use the System.totalMemory, but there's no equivalent in ActionScript 2.0. AS3 also has Font.enumerateFonts, and a few other things that are different from system to system. On the server side I also add the IP address to the session ID, but even that isn't enough (for example, many large companies use a single proxy server and that means that thousands of people all have the same IP -- and since they tend to look at the same sites, with the same ads, roughly at the same time, there are many session ID collisions). What I need isn't something perfectly random, just something that is random enough to dilute the randomness I get from Math.random(). Think of it this way: there is a certain chance that two people will generate the same random number sequence using only Math.random(), but the chance of two people generating the same sequence and having, say, the exact same list of fonts is significantly lower. I cannot rely on having sufficient script access to use ExternalInterface to get hold of things like the user agent, or the URL of the page. I don't need suggestions of how to do it in AS3, or any other system, only AS2 -- using only what's available in the standard APIs. The best I've come up with so far is to use the list of microphones (Microphone.names), but I've also tried to make some fingerprinting using some of the properties in System.capabilities, I'm not sure how much randomness I can get out of that though so I'm not using that at the moment. I hope I've overlooked something.

• iPhone SDK allow touches to affect multiple views

  - by Parad0x13

  I have a main view that has has two buttons on it that control methods to display the next image and display the previous image. In this case the 'Image' is a class that inherits from UIImageView and has multiple pictures on it that you can interact with, and I call this class a 'Pane'. The pane itself handles all the user interaction itself while the main view controls the display of next and previous panes with the buttons. Here is my dilemma, because the pane fully covers the main view it wont allow for the user to tap the buttons on the main view! So once a pane pops up you cannot change it via the buttons! Is there a way to allow touches through transparent parts of a view, or if not how in the world do I achieve this?! I cannot pass touchesBegan or any of those methods from the pane to the superview because all of the button touch methods are created in the xib file. I cannot insert the pane under the control panel because then you wouldn't be able to interact with the pane. And as far as I know theres no way to pass touch events to every single pane within the paneHoldingArray that belongs to the main view I cannot add the command buttons inside of the pane because I want to be able to replace the command button's image with a thumbprint render of the next/previous pane. I've been stuck on this for a very long time, please somebody help me out with a fix action or a new way to re-engineer the code so that it will work!

• 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

• Drupal Views api, add simple argument handler

  - by LanguaFlash

  Background: I have a complex search form that stores the query and it's hash in a cache. Once the cache is set, I redirect to something like /searchresults/e6c86fadc7e4b7a2d068932efc9cc358 where that big long string on the end is the md5 hash of my query. I need to make a new argument for views to know what the hash is good for. The reason for all this hastle is because my original search form is way to complex and has way to many arguments to consider putting them all into the path and expecting to do the filtering with the normal views arguments. Now for my question. I have been reading views 2 documentation but not figuring out how to accomplish this custom argument. It doesn't seem to me like this should be as hard as it seems to me like it must be. Leaving aside any knowledge of the veiws api, it would seem that all I need is a callback function that will take the argument from the path as it's only argument and return a list of node id's to filter to. Can anyone point me to a solution or give me some example code? Thanks for your help! You guys are great. PS. I am pretty sure that my design is the best I can come up with, lets don't get off my question and into cross checking my design logic if we can help it.
