  • mysql match against russain

    - by Devenv
    Hey, Trying to solve this for a very long time now... SELECT MATCH(name) AGAINST('????????') (russian) doesn't work, but SELECT MATCH(name) AGAINST('abraxas') (english) work perfectly. I know it's something with character-set, but I tried all kind of settings and it didn't work. For now it's latin-1. LIKE works This is the show variables charset related: character_set_client - latin1 character_set_connection - latin1 character_set_database - latin1 character_set_filesystem - binary character_set_results - latin1 character_set_server - latin1 character_set_system - utf8 character_sets_dir - /usr/share/mysql/charsets/ collation_connection - latin1_swedish_ci collation_database - latin1_swedish_ci collation_server - latin1_swedish_ci chunk of /etc/my.cnf default-character-set=latin1 skip-character-set-client-handshake chunk of the dump: /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8 */; DROP TABLE IF EXISTS `scenes_raw`; /*!40101 SET @saved_cs_client = @@character_set_client */; /*!40101 SET character_set_client = utf8 */; CREATE TABLE `scenes_raw` ( `scene_name` varchar(40) DEFAULT NULL, ...blabla... ) ENGINE=MyISAM AUTO_INCREMENT=901 DEFAULT CHARSET=utf8; (I did tests without skip-character-set-client-handshake too) SHOW TABLE STATUS WHERE Name = 'scenes_raw'\G Name: scenes_raw Engine: MyISAM Version: 10 Row_format: Dynamic Index_length: 23552 Collation: utf8_general_ci Checksum: NULL Create_options:

  • Optimal Serialization of Primitive Types

    - by Greg Dean
    We are beginning to roll out more and more WAN deployments of our product (.Net fat client w/ IIS hosted Remoting backend). Because of this we are trying to reduce the size of the data on the wire. We have overridden the default serialization by implementing ISerializable (similar to this), we are seeing anywhere from 12% to 50% gains. Most of our efforts focus on optimizing arrays of primitive types. I would like to know if anyone knows of any fancy way of serializing primitive types, beyond the obvious? For example today we serialize an array of ints as follows: [4-bytes (array length)][4-bytes][4-bytes] Can anyone do significantly better? The most obvious example of a significant improvement, for boolean arrays, is putting 8 bools in each byte, which we already do. Note: Saving 7 bits per bool may seem like a waste of time, but when you are dealing with large magnitudes of data (which we are), it adds up very fast. Note: We want to avoid general compression algorithms because of the latency associated with it. Remoting only supports buffered requests/responses(no chunked encoding). I realize there is a fine line between compression and optimal serialization, but our tests indicate we can afford very specific serialization optimizations at very little cost in latency. Whereas reprocessing the entire buffered response into new compressed buffer is too expensive.

  • x86_64 Assembly Command Line Arguments

    - by Brandon oubiub
    I'm new to assembly, and I just got familiar with the call stack, so bare with me. To get the command line arguments in x86_64 on Mac OS X, I can do the following: _main: sub rsp, 8 ; 16 bit stack alignment mov rax, 0 mov rdi, format mov rsi, [rsp + 32] call _printf Where format is "%s". rsi gets set to argv[0]. So, from this, I drew out what (I think) the stack looks like initially: top of stack <- rsp after alignment return address <- rsp at beginning (aligned rsp + 8) [something] <- rsp + 16 argc <- rsp + 24 argv[0] <- rsp + 32 argv[1] <- rsp + 40 ... ... bottom of stack And so on. Sorry if that's hard to read. I'm wondering what [something] is. After a few tests, I find that it is usually just 0. However, occasionally, it is some (seemingly) random number. EDIT: Also, could you tell me if the rest of my stack drawing is correct?

  • Basic jUnit Questions

    - by Epitaph
    I was testing a String multiplier class with a multiply() method that takes 2 numbers as inputs (as String) and returns the result number (as String) `public String multiply(String num1, String num2); I have done the implementation and created a test class with the following test cases involving the input String parameter as 1) valid numbers 2) characters 3) special symbol 4) empty string 5) Null value 6) 0 7) Negative number 8) float 9) Boundary values 10) Numbers that are valid but their product is out of range 11) numbers will + sign (+23) 1) I'd like to know if "each and every" assertEquals() should be in it's own test method? Or, can I group similar test cases like testInvalidArguments() to contains all asserts involving invalid characters since ALL of them throw the same NumberFormatException ? 2) If testing an input value like character ("a"), do I need to include test cases for ALL scenarios? "a" as the first argument "a" as the second argument "a" and "b" as the 2 arguments 3) As per my understanding, the benefit of these unit tests is to find out the cases where the input from a user might fail and result in an exception. And, then we can give the user with a meaningful message (asking them to provide valid input) instead of an exception. Is that the correct? And, is it the only benefit? 4) Are the 11 test cases mentioned above sufficient? Did I miss something? Did I overdo? When is enough? 5) Following from the above point, have I successfully tested the multiply() method?

  • In Seam what's the difference between injected EntityManager and getEntityManager from EntityHome

    - by Navi
    I am testing a Seam application using the needle test API. In my code I am using the getEntityManager() method from EntityHome. When I run the unit tests against an in memory database I get the following exception: java.lang.IllegalStateException: No application context active at org.jboss.seam.Component.forName(Component.java:1945) at org.jboss.seam.Component.getInstance(Component.java:2005) at org.jboss.seam.Component.getInstance(Component.java:1983) at org.jboss.seam.Component.getInstance(Component.java:1977) at org.jboss.seam.Component.getInstance(Component.java:1972) at org.jboss.seam.framework.Controller.getComponentInstance(Controller.java:272) at org.jboss.seam.framework.PersistenceController.getPersistenceContext(PersistenceController.java:20) at org.jboss.seam.framework.EntityHome.getEntityManager(EntityHome.java:177) etc .. I can resolve some of these errors by injecting the EntityManager with @In EntityManager entityManager; Unfortunately the persist method of EntityHome also calls the getEntityManager. This means a lot of mocks or rewriting the code somehow. Is there any workaround and why is this exception thrown anyway? I am using Seam 2.2.0 GA by the way. There is nothing special about the components. They are generated by seam-gen. The test is performed with in memory database - I followed the examples in http://jbosscc-needle.sourceforge.net/jbosscc-needle/1.0/db-util.html.

  • Generating equals / hashcode / toString using annotation

    - by Bruno Bieth
    I believe I read somewhere people generating equals / hashcode / toString methods during compile time (using APT) by identifying which fields should be part of the hash / equality test. I couldn't find anything like that on the web (I might have dreamed it ?) ... That could be done like that : public class Person { @Id @GeneratedValue private Integer id; @Identity private String firstName, lastName; @Identity private Date dateOfBirth; //... } For an entity (so we want to exlude some fields, like the id). Or like a scala case class i.e a value object : @ValueObject public class Color { private int red, green, blue; } Not only the file becomes more readable and easier to write, but it also helps ensuring that all the attributes are part of the equals / hashcode (in case you add another attribute later on, without updating the methods accordingly). I heard APT isn't very well supported in IDE but I wouldn't see that as a major issue. After all, tests are mainly run by continuous integration servers. Any idea if this has been done already and if not why ? Thanks

  • Emulating a web browser

    - by Sean
    Hello, we are tasked with basically emulating a browser to fetch webpages, looking to automate tests on different web pages. This will be used for (ideally) console-ish applications that run in the background and generate reports. We tried going with .NET and the WatiN library, but it was built on a Marshalled IE, and so it lacked many features that we hacked in with calls to unmanaged native code, but at the end of the day IE is not thread safe nor process safe, and many of the needed features could only be implemented by changing registry values and it was just terribly unflexible. Proxy support JavaScript support- we have to be able to parse the actual DOM after any javascript has executed (and hopefully an event is raised to handle any ajax calls) Ability to save entire contents of page including images FROM THE loaded page's CACHE to a separate location ability to clear cookies/cache, get the cookies/cache, etc. Ability to set headers and alter post data for any browser call And for the love of drogs, an API that isn't completely cryptic Languages acceptable C++, C#, Python, anything that can be a simple little console application that doesn't have a retarded syntax like Ruby. From my own research, and believe me I am terrible at google searches, I have heard good things about WebKit... would the Qt module QtWebKit handle all these features?

  • How to organize the work when project needs to be re-implemented due to poor code quality?

    - by Dmitriy Nagirnyak
    Hi, I have joined a very small where one main developer has been buiding the web app (.NET 4.0) during ~6 months. The project should be delivered within next 2 months. After first look at the code I can say that I would never allow it to go to production (things like catch { }, not tests at all with WebForms etc). So the code quality is incredibly low. My task is to improve that and still deliver the solution. So I plan to start with unit testing and MVC2 reimplementing most of the functionality (though using some of the existing code). I estimate that I will need about 6 weeks to catch up with the current progress and be on te same functionality level as the application will be in 6 months. The problem is that the main developer who has been working on the project does not seem to be very 'professional' and skillful (he seems to be really starting in IT and many basic things are unknown to him). It will take significant amount of time and effort to educate him how to do the proper testing, development and apply some patterns. I am ready to take responsibility for the reimplemnting the application but at the same time I don't want the main developer to be on idle but as he won't be able to significantly contribute to the better-world project at this stage I am not sure what would the best way to keep productivity high for both of us. Currently I think following solution is good enough: He proceeds doing what he does until I will catch up with him and then start working on a new project together. The problem is that of course this approach is not very productive as one developer will do better-world project while the other will proceed with what he did, effectively doing similar tasks. Can you suggest how we could better organise the work together in order to be most efficient for the overall project? Thanks, Dmitriy.

  • How do I grant a site's applet an AllPermission privilege?

    - by nahsra
    I'd like to specify certain applets to run with java.security.AllPermission on my computer (for debugging and security testing). However, I don't want to enable all applets that I run to have this permission. So, editing my user Java policy file (which I have ensured is the correct policy file through testing), I try to put this value: grant codeBase "http://host_where_applet_lives/-" { permission java.security.AllPermission; }; This value fails when the applet tries to do something powerful (create a new Thread, in my case). However, when I put the following value: grant { permission java.security.AllPermission; }; The applet is able to perform the powerful operation. The only difference is the lack of a codeBase attribute. An answer to a similar question asked here [1] seemed to suggest (but never show or prove) that AccessController.doPrivileged() calls may be required. To me, this sounds wrong as I don't need that call when I grant the permissions to all applets (the second example I showed). Even if this is a solution, littering the applets I run with AccessController.doPrivileged() calls is not easy or necessarily possible. To top it off, my tests show that this just doesn't work anyway. But I'm happy to hear more ideas around it.

  • Hyperlink regex including http(s):// not working in C#

    - by Rory Fitzpatrick
    I think this is sufficiently different from similar questions to warrant a new one. I have the following regex to match the beginning hyperlink tags in HTML, including the http(s):// part in order to avoid mailto: links <a[^>]*?href=[""'](?<href>\\b(https?)://[^\[\]""]+?)[""'][^>]*?> When I run this through Nregex (with escaping removed) it matches correctly for the following test cases: <a href="http://www.bbc.co.uk"> <a href="http://bbc.co.uk"> <a href="https://www.bbc.co.uk"> <a href="mailto:[email protected]"> However when I run this in my C# code it fails. Here is the matching code: public static IEnumerable<string> GetUrls(this string input, string matchPattern) { var matches = Regex.Matches(input, matchPattern, RegexOptions.Compiled | RegexOptions.IgnoreCase); foreach (Match match in matches) { yield return match.Groups["href"].Value; } } And my tests: @"<a href=""https://www.bbc.co.uk"">bbc</a>".GetUrls(StringExtensions.HtmlUrlRegexPattern).Count().ShouldEqual(1); @"<a href=""mailto:[email protected]"">bbc</a>".GetUrls(StringExtensions.HtmlUrlRegexPattern).Count().ShouldEqual(0); The problem seems to be in the \\b(https?):// part which I added, removing this passes the normal URL test but fails the mailto: test. Anyone shed any light?

  • Python Pre-testing for exceptions when coverage fails

    - by Tal Weiss
    I recently came across a simple but nasty bug. I had a list and I wanted to find the smallest member in it. I used Python's built-in min(). Everything worked great until in some strange scenario the list was empty (due to strange user input I could not have anticipated). My application crashed with a ValueError (BTW - not documented in the official docs). I have very extensive unit tests and I regularly check coverage to avoid surprises like this. I also use Pylint (everything is integrated in PyDev) and I never ignore warnings, yet I failed to catch this bug before my users did. Is there anything I can change in my methodology to avoid these kind of runtime errors? (which would have been caught at compile time in Java / C#?). I'm looking for something more than wrapping my code with a big try-except. What else can I do? How many other build in Python functions are hiding nasty surprises like this???

  • EJB3Unit testing no-tx-datasource

    - by justastefan
    Hello, I am doing tests on an ejb3-project using ejb3unit http://ejb3unit.sourceforge.net/Session-Bean.html for testing. All my Services long for @PersistenceContext (UnitName=bla). I set up the ejb3unit.properties like this: ejb3unit_jndi.1.isSessionBean=true ejb3unit_jndi.1.jndiName=ejb/MyServiceBean ejb3unit_jndi.1.className=com.company.project.MyServiceBean everything works with the in-memory-database. So now i want additionally test another servicebean with @PersistenceContext (UnitName=noTxDatasource) that goes for a defined in my datasources.xml: <datasources> <local-tx-datasource> ... </local-tx-datasource> <no-tx-datasource> <jndi-name>noTxDatasource</jndi-name> <connection-url>...</connection-url> <driver-class>oracle.jdbc.OracleDriver</driver-class> <user-name>bla</user-name> <password>bla</password> </no-tx-datasource> </datasources> How do I tell ejb3unit to make this work: Object object = InitialContext.doLookup("java:/noTxDatasource"); if (object instanceof DataSource) { return ((DataSource) object).getConnection(); } else { return null; } Currently it fails saying: javax.NamingException: Cannot find the name (noTxDataSource) in the JNDI tree Current bindings: (ejb/MyServiceBean=com.company.project.MyServiceBean) How can I add this no-tx-datasource to the jndi bindings?

  • .NET regex's not working - 1# check beginning of text entered #2 check structure

    - by Olly
    OK it has unfortunately been a while since I've used REGEX and I am struggling to wonder why its not working with my project. I have used Regex Tester which says my two tests are valid but when it comes to testing in my project they get rejected. 1) Check the text starts with certain characters [RegularExpression("(spAPP)",ErrorMessage = "Stored procedures must begin with spAPP")] This seems to accept spAPP on it's own, but not something like spAPPabcdef which I want it to. I am struggling to find the "Ignore rest of the text" attribute with REGEX. 2) A bit more complicated. I have certain naming conventions for AD groups, so an example would be "UK ROLE IT APPLICATION DEV ADMIN", up to the role name there are standards (so I need the "UK ROLE IT APPLICATION DEV" checked. [RegularExpression(@"((UK|FRANCE|GERMANY|USA)\s(ROLE)\s(IT|NON-IT)\s(APPLICATION)\s(DEV|TEST|LIVE))", ErrorMessage = "Please use AD naming standards.")] I think it might be the fact I am using () around all the words, but its easier to read in my code. The RegexTester I found seems to indicate that it's right, but again, in my .NET project, it rejects it. Thanks,

  • In Ruby, how to implement global behaviour?

    - by Gordon McAllister
    Hi all, I want to implement the concept of a Workspace. This is a global concept - all other code will interact with one instance of this Workspace. The Workspace will be responsible for maintaining the current system state (i.e. interacting with the system model, persisting the system state etc) So what's the best design strategy for my Workspace, bearing in mind this will have to be testable (using RSpec now, but happy to look at alternatives). Having read thru some open source projects out there and I've seen 3 strategies. None of which I can identify as "the best practice". They are: Include the singleton class. But how testable is this? Will the global state of Workspace change between tests? Implemented all behaviour as class methods. Again how do you test this? Implemented all behaviour as module methods. Not sure about this one at all! Which is best? Or is there another way? Thanks, Gordon

  • Unit test for Web Forms MVP presenter has a null Model

    - by jacksonakj
    I am using Web Forms MVP to write an DotNetNuke user control. When the 'SubmitContactUs' event is raised in my unit test the presenter attempts to set the 'Message' property on the Modal. However the View.Modal is null in the presenter. Shouldn't the Web Forms MVP framework automatically build a new View.Model object in the presenter? It could be that the 'Arrange' portion of my test is missing something that the presenter needs. Any help would be appreciated. Here is my test: using System; using AthleticHost.ContactUs.Core.Presenters; using AthleticHost.ContactUs.Core.Views; using Xunit; using Moq; namespace AthleticHost.ContactUs.Tests { public class ContactUsPresenterTests { [Fact] public void ContactUsPresenter_Sets_Message_OnSubmit() { // Arrange var view = new Mock<IContactUsView>(); var presenter = new ContactUsPresenter(view.Object); // Act view.Raise(v => v.Load += null, new EventArgs()); view.Raise(v => v.SubmitContactUs += null, new SubmitContactUsEventArgs("Chester", "Tester", "[email protected]", "http://www.test.com", "This is a test of the emergancy broadcast system...")); presenter.ReleaseView(); // Assert Assert.Contains("Chester Tester", view.Object.Model.Message); } } }

  • BDD on Rails - Is the community more behind Shoulda or RSpec?

    - by Wayne M
    For a new application I want to start dabbling in BDD and I'm trying to decide between using RSpec or Thoughtbot's Shoulda. I like the macros that Shoulda uses, and the fact that it doesn't seem to reinvent the way Ruby/Rails does testing, but simply provides an add-on. On the other hand, the macros seem like a bit too much "magic" instead of being explicit about what you're testing (however I know from dabbling that it's annoying to write a dozen "should be invalid without xxx" two-liners on a model). To be honest I find writing specifications/tests for models to be trivially and almost boringly easy, but I find writing them for controllers to be insanely difficult because I'm never sure exactly what I should be testing or how to write it. I'm iffy on the subject of mocking and stubbing since I think they give you false assumptions (since you can just tell it to think it has whatever data you need or to pretend that Method X was called) and I know that RSpec makes heavy use of both of them. I like the documentation that RSPec produces but I'm creating an application for sale, not to give to a client so the pretty documentation isn't that useful. I like Cucumber but it seems like overkill (and yes I know it can be used with Shoulda). At this point is the Rails community in favor of RSpec or Shoulda?

  • Can I use Data URLs in Android 2.1's Webkit-based browser?

    - by Sven Haiges
    Hi all, I am writing a tutorial about the HTML5 Canvas for mobile and did some basic tests. While I can call the getDataURL() Method on an iPhone's HTML5 Canvas Element, it does not seem to return the data URL on Android 2.1 (Google Nexus One) and it's webkit-based default browser. Here is the sample: var dataURL = canvas.toDataURL(); var img = document.createElement('img'); img.setAttribute('src', dataURL); document.getElementById('box').appendChild(img); This will work on iPhone, it will add a new image element with the same content as the canvas. It does nothing or fails on Android 2.1. Has anyone ever gotten this to work? I am also wondering if anyone could help me with understanding the WebKit Build numbers and what it means with regards to what features I can expect. For the iphone, I see a build number of 528.18, on Android 2.1's Browser I see (from the user agent strign) a WebKit build 530.17. So it looks Android 2.1's webkit browser is more up to date, still some features work on iPhone's webkit but not on Android. Does this comparison just make no sense? Thanx all!

  • vsts load test datasource issues

    Hello, I have a simple test using vsts load test that is using datasource. The connection string for the source is as follows <connectionStrings> <add name="MyExcelConn" connectionString="Driver={Microsoft Excel Driver (*.xls)};Dsn=Excel Files;dbq=loginusers.xls;defaultdir=.;driverid=790;maxbuffersize=4096;pagetimeout=20;ReadOnly=False" providerName="System.Data.Odbc" /> </connectionStrings> the datasource configuration is as follows and i am getting following error estError TestError 1,000 The unit test adapter failed to connect to the data source or to read the data. For more information on troubleshooting this error, see "Troubleshooting Data-Driven Unit Tests" (http://go.microsoft.com/fwlink/?LinkId=62412) in the MSDN Library. Error details: ERROR [42000] [Microsoft][ODBC Excel Driver] Cannot update. Database or object is read-only. ERROR [IM006] [Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed ERROR [42000] [Microsoft][ODBC Excel Driver] Cannot update. Database or object is read-only. I wrote a test, just to check if i could create an odbc connection would work and that works the test is as follows [TestMethod] public void TestExcelFile() { string connString = ConfigurationManager.ConnectionStrings["MyExcelConn"].ConnectionString; using (OdbcConnection con = new OdbcConnection(connString)) { con.Open(); System.Data.Odbc.OdbcCommand objCmd = new OdbcCommand("SELECT * FROM [loginusers$]"); objCmd.Connection = con; OdbcDataAdapter adapter = new OdbcDataAdapter(objCmd); DataSet ds = new DataSet(); adapter.Fill(ds); Assert.IsTrue(ds.Tables[0].Rows.Count > 1); } } any ideas ?

  • Selenium RC throws sessionsid should not be null exception, phpunit 3.4 bug only?

    - by user342775
    I am looking to migrate my selenium RC tests to using PHPUnit 3.4.12 from PHPUnit 3.3.2 The selenium test will fail with an exception of the following when I use assertTextPresent() PHPUnit_Framework_Exception: Response from Selenium RC server for getLocation(). ERROR Server Exception: sessionId should not be null; has this session been started yet?. For example: public function testSending($browser) { ... $browser->click("send"); $browser->waitForPageToLoad("30000"); $browser->assertTextPresent("text"); } Below is the selenium RC log (running on Windows): 15:40:19.676 INFO - Command request: isTextPresent[text, ] on session 153d03a123c42098711994f43c2db34 15:40:19.691 INFO - Got result: OK,false on session 153d023a123c42098711994f43cdb34 15:40:19.879 INFO - Command request: testComplete[, ] on session 153d023a123c4298711994f43c2db34 15:40:19.879 INFO - Killing Firefox... 15:40:20.269 INFO - Got result: OK on session 153d023a123c42098711994f43c2db34 15:40:20.472 INFO - Command request: getLocation[, ] on session null 15:40:20.472 ERROR - Exception running 'getLocation 'command on session null java.lang.NullPointerException: sessionId should not be null; has this session been started yet? As you can see, the test should have completed as indicated by the "Killing Firefox" bit, but it instead continued to do something else and triggered the getLocation[, ] command which caused the exception. I have tried the same test with PHPUnit 3.3.2 which did not produce this problem - the test would happily end without the getLocation(). Any ideas? thanks

  • Using Moq callbacks correctly according to AAA

    - by Hadi Eskandari
    I've created a unit test that tests interactions on my ViewModel class in a Silverlight application. To be able to do this test, I'm mocking the service interface, injected to the ViewModel. I'm using Moq framework to do the mocking. to be able to verify bounded object in the ViewModel is converted properly, I've used a callback: [Test] public void SaveProposal_Will_Map_Proposal_To_WebService_Parameter() { var vm = CreateNewCampaignViewModel(); var proposal = CreateNewProposal(1, "New Proposal"); Services.Setup(x => x.SaveProposalAsync(It.IsAny<saveProposalParam>())).Callback((saveProposalParam p) => { Assert.That(p.plainProposal, Is.Not.Null); Assert.That(p.plainProposal.POrderItem.orderItemId, Is.EqualTo(1)); Assert.That(p.plainProposal.POrderItem.orderName, Is.EqualTo("New Proposal")); }); proposal.State = ObjectStates.Added; vm.CurrentProposal = proposal; vm.Save(); } It is working fine, but if you've noticed, using this mechanism the Assert and Act part of the unit test have switched their parts (Assert comes before Acting). Is there a better way to do this, while preserving correct AAA order?

  • Mocking with Boost::Test

    - by Billy ONeal
    Hello everyone :) I'm using the Boost::Test library for unit testing, and I've in general been hacking up my own mocking solutions that look something like this: //In header for clients struct RealFindFirstFile { static HANDLE FindFirst(LPCWSTR lpFileName, LPWIN32_FIND_DATAW lpFindFileData) { return FindFirstFile(lpFileName, lpFindFileData); }; }; template <typename FirstFile_T = RealFindFirstFile> class DirectoryIterator { //.. Implementation } //In unit tests (cpp) #define THE_ANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING 42 struct FakeFindFirstFile { static HANDLE FindFirst(LPCWSTR lpFileName, LPWIN32_FIND_DATAW lpFindFileData) { return THE_ANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING; }; }; BOOST_AUTO_TEST_CASE( MyTest ) { DirectoryIterator<FakeFindFirstFile> LookMaImMocked; //Test } I've grown frustrated with this because it requires that I implement almost everything as a template, and it is a lot of boilerplate code to achieve what I'm looking for. Is there a good method of mocking up code using Boost::Test over my Ad-hoc method? I've seen several people recommend Google Mock, but it requires a lot of ugly hacks if your functions are not virtual, which I would like to avoid. Oh: One last thing. I don't need assertions that a particular piece of code was called. I simply need to be able to inject data that would normally be returned by Windows API functions.

  • Optimizing PHP require_once's for low disk i/o?

    - by buggedcom
    Q1) I'm designing a CMS (-who isn't!) but priority is being given to caching. Literally everything is cached. DB rows, DB id queries, Configuration data, processed data, compiled templates. Currently it has two layers of caching. The first is a opcode cache or memory cache such as apc, eaccelerator, xcache or memcached. If an entry is not found in there it is then searched for in the secondary slow cache, ie php includes. Are the opcode caches actually faster than doing a require_once to a php file with a var_export'd array of data in it? My tests are inconclusive as my development box (5.3 of XAMPP) keeps throwing errors installing any of the aforementioned programs. Q2) The CMS has numerous helper classes that are autoloaded on demand instead of loading all files. Mostly each has a require before it so no autoloading needs to take place, however this is not the question. Because a page script can have up to 50/60 helper files included I have a feeling that if the site was under pressure it would buckle because of all the i/o that this incurs. Ignore for the moment that there is output cache in place that would remove the need for what I am about to suggest, and also that opcode caches would render this moot. What I have tried to do is join all the helper files required for the scripts execution in one single file. This is achievable and works well, however it has a side effect of greatly increasing the memory usage dramatically even though technically the same code is being used. What are your thoughts and opinions on this?
