• Configuring xUnit test output in Hudson

  - by graham.reeds

  I have a simple PoC project in Hudson. The PoC has unit tests written via UnitTest++ and outputs the results as XML for consumption by xUnit to munge into jUnit format. Here are the salient relevant I have my project configured to use MSBuild to build the 2008 solution. The project contains both the dll it is to build and the unit tests which are run as a post-build step. My workspace in Hudson is set to c:\develop\money (Money is the name of the project) and in the Hudson console I can see the workspace folders, the solution file and output folders (/bin, /doc, etc). The test console app outputs its file 'money_unit_tests.xml' to the folder 'reports' (making c:\develop\money\reports). I've restarted Hudson since installing xUnit and setting the workspace. However when I start Hudson building I am given the following message: [xUnit] Starting to record. [xUnit] [UnitTest] - Use the embedded style sheet. [xUnit] [ERROR] - No test report file(s) were found with the pattern 'reports/money_unit_tests.xml' relative to 'C:\.hudson\jobs\Money\workspace' for the testing framework 'UnitTest'. Did you enter a pattern relative to the correct directory? Did you generate the result report(s) for 'UnitTest'? [xUnit] Stopping recording. Finished: FAILURE Why does Hudson seem to think the workspace is in C:.hudson... and not C:\Develop...? What can I do change it? If I can't change it, what can I do to mitigate these changes? (I don't exactly want to hardcode the output for the xml to C:.hudson...)

• Is HttpContextWrapper all that....useful?

  - by bakasan

  I've been going through the process of cleaning up our controller code to make each action as testable. Generally speaking, this hasn't been too difficult--where we have opportunity to use a fixed object, like say FormsAuthentication, we generally introduce some form of wrapper as appropriate and be on our merry way. For reasons not particularly germaine to this conversation, when it came to dealing with usage of HttpContext, we decided to use the newly created HttpContextWrapper class rather than inventing something homegrown. One thing we did introduce was the ability to swap in a HttpContextWrapper (like say, for unit testing). This was wholly inspired by the way Oren Eini handles unit testing with DateTimes (see article, a pattern we also use) public static class FooHttpContext { public static Func<HttpContextWrapper> Current = () => new HttpContextWrapper(HttpContext.Current); public static void Reset() { Current = () => new HttpContextWrapper(HttpContext.Current); } } Nothing particularly fancy. And it works just fine in our controller code. The kicker came when we go to write unit tests. We're using Moq as our mocking framework, but alas var context = new Mock<HttpContextWrapper>() breaks since HttpContextWrapper doesn't have a parameterless ctor. And what does it take as a ctor parameter? A HttpContext object. So I find myself in a catch 22. I'm using the prescribed way to decouple HttpContext--but I can't mock a value in because the original HttpContext object was sealed and therefore difficult to test. I can map HttpContextBase, which both derive from--but that doesn't really get me what I'm after. Am I just missing the point somewhere with regard to HttpContextWrapper? I can find ways to work around the issue, but we are kind of fond of remaining consistent in decoupling using the Function delegate pattern--but it seems like we're not fully grokking intent of the wrapper.

• How to let Tomcat publish WSDL for the WS it provides (CXF 2.2, Spring 3, Tomcat6)

  - by Zwei Steinen

  Hi, I am trying to implement a simple web service provider using Tomcat6, CXF 2.2, Spring 3, and actually the service itself runs fine (I can call web methods using the original WSDL and SoapUI). However, Tomcat returns a blank page on "?wsdl" requests. Also, when I try to manipulate the (would-be) published WSDL by adding a publishedEndpointURL property to the jaxws:endpoint element, Tomcat will issue a XML parse exception (something like property publishedEndpointURL is not allowed in element jaxws:endpoint) <jaxws:endpoint id="service" implementor="org.sample.ServiceImpl" implementorClass="org.sample.ServiceImpl" address="/service" publishedEndpointURL="http://localhost:8080/MyService/service"> I used "contract first" style. EDIT: What I did so far: Setup tomcat6 with Spring3 Generate CXF implementation class by using maven Provide web.xml (only relevant part shown) <listener> <listener-class>org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <servlet> <servlet-name>cxf</servlet-name> <servlet-class> org.apache.cxf.transport.servlet.CXFServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>cxf</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> Provide applicationContext.xml (only relevant part is shown) Package generated stuff into war and deploy

• Websphere 7 simple realm (like tomcat-users.xml)

  - by Heavy Bytes

  I am trying to port a J2EE app from Tomcat to Websphere and I'm not too familiar with Websphere. The only problem I am having is authorization (I use basic-authentication in my web.xml). In Tomcat I use the tomcat-users.xml file to define my users/passwords and to what roles they belong. How do I do this "simply" in Websphere? When deploying the EAR to Websphere it also asks me to map my role from web.xml to a user or group. Do I have to set up some sort of realm? Custom user registry? Thanks. UPDATE: I configured a Standalone custom registry, however I can't get a log-in prompt for username/password. It works just fine in Tomcat, and it doesn't in Websphere. Code from web.xml <security-constraint> <web-resource-collection> <web-resource-name>basic-auth security</web-resource-name> <url-pattern>/*</url-pattern> </web-resource-collection> <auth-constraint> <role-name>HELLO_USER</role-name> </auth-constraint> <user-data-constraint>NONE</user-data-constraint> </security-constraint> <login-config> <auth-method>BASIC</auth-method> </login-config> <security-role> <role-name>HELLO_USER</role-name> </security-role>

• jax-ws on glassfish3 init method

  - by Alex

  Hi all, I've created simple jax-ws (anotated Java 6 class to web service) service and deploied it on glassfish v3. The web.xml <?xml version="1.0" encoding="ISO-8859-1"?> <web-app> <servlet> <servlet-name>MyServiceName</servlet-name> <description>Blablabla</description> <servlet-class>com.foo-bar.somepackage.TheService</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>MyServiceName</servlet-name> <url-pattern>/MyServiceName</url-pattern> </servlet-mapping> <session-config> <session-timeout>30</session-timeout> </session-config> </web-app> There is no sun-jaxws.xml in the war. The service works fine but I have 2 issues: I'm using apache common configuration package to read my configuration, so i have init function that calls configuration stuff. 1. How can I configure init method for jaxws service (like i can do for the servlets for example) 2. the load on startup parameter is not affecting the service, I see that for every request init function called again (and c-tor). How can I set scope for my service? Thanks a lot,

• Atomic UPSERT in SQL Server 2005

  - by rabidpebble

  What is the correct pattern for doing an atomic "UPSERT" (UPDATE where exists, INSERT otherwise) in SQL Server 2005? I see a lot of code on SO (e.g. see http://stackoverflow.com/questions/639854/tsql-check-if-a-row-exists-otherwise-insert) with the following two-part pattern: UPDATE ... FROM ... WHERE <condition> -- race condition risk here IF @@ROWCOUNT = 0 INSERT ... or IF (SELECT COUNT(*) FROM ... WHERE <condition>) = 0 -- race condition risk here INSERT ... ELSE UPDATE ... where will be an evaluation of natural keys. None of the above approaches seem to deal well with concurrency. If I cannot have two rows with the same natural key, it seems like all of the above risk inserting rows with the same natural keys in race condition scenarios. I have been using the following approach but I'm surprised not to see it anywhere in people's responses so I'm wondering what is wrong with it: INSERT INTO <table> SELECT <natural keys>, <other stuff...> FROM <table> WHERE NOT EXISTS -- race condition risk here? ( SELECT 1 FROM <table> WHERE <natural keys> ) UPDATE ... WHERE <natural keys> (Note: I'm assuming that rows will not be deleted from this table. Although it would be nice to discuss how to handle the case where they can be deleted -- are transactions the only option? Which level of isolation?) Is this atomic? I can't locate where this would be documented in SQL Server documentation.

• Improving long-polling Ajax performance

  - by Bears will eat you

  I'm writing a webapp (Firefox-compatible only) which uses long polling (via jQuery's ajax abilities) to send more-or-less constant updates from the server to the client. I'm concerned about the effects of leaving this running for long periods of time, say, all day or overnight. The basic code skeleton is this: function processResults(xml) { // do stuff with the xml from the server } function fetch() { setTimeout(function () { $.ajax({ type: 'GET', url: 'foo/bar/baz', dataType: 'xml', success: function (xml) { processResults(xml); fetch(); }, error: function (xhr, type, exception) { if (xhr.status === 0) { console.log('XMLHttpRequest cancelled'); } else { console.debug(xhr); fetch(); } } }); }, 500); } (The half-second "sleep" is so that the client doesn't hammer the server if the updates are coming back to the client quickly - which they usually are.) After leaving this running overnight, it tends to make Firefox crawl. I'd been thinking that this could be partially caused by a large stack depth since I've basically written an infinitely recursive function. However, if I use Firebug and throw a breakpoint into fetch, it looks like this is not the case. The stack that Firebug shows me is only about 4 or 5 frames deep, even after an hour. One of the solutions I'm considering is changing my recursive function to an iterative one, but I can't figure out how I would insert the delay in between Ajax requests without spinning. I've looked at the JS 1.7 "yield" keyword but I can't quite wrap my head around it, to figure out if it's what I need here. Is the best solution just to do a hard refresh on the page periodically, say, once every hour? Is there a better/leaner long-polling design pattern that won't put a hurt on the browser even after running for 8 or 12 hours? Or should I just skip the long polling altogether and use a different "constant update" pattern since I usually know how frequently the server will have a response for me?

• Design Patterns Recommendation for Filtering Option

  - by Tarik

  Hi people, I am thinking to create a filter object which filters and delete everything like html tags from a context. But I want it to be independent which means the design pattern I can apply will help me to add more filters in the future without effecting the current codes. I thought Abstract Factory but it seems it ain't gonna work out the way I want. So maybe builder but it looks same. I don't know I am kinda confused, some one please recommend me a design pattern which can solve my problem but before that let me elaborate the problem a little bit. Lets say I have a class which has Description field or property what ever. And I need filters which remove the things I want from this Description property. So whenever I apply the filter I can add more filter in underlying tier. So instead of re-touching the Description field, I can easily add more filters and all the filters will run for Description field and delete whatever they are supposed to delete from the Description context. I hope I could describe my problem. I think some of you ran into the same situation before. Thanks in advance...

• Sync Vs. Async Sockets Performance in C#

  - by Michael Covelli

  Everything that I read about sockets in .NET says that the asynchronous pattern gives better performance (especially with the new SocketAsyncEventArgs which saves on the allocation). I think this makes sense if we're talking about a server with many client connections where its not possible to allocate one thread per connection. Then I can see the advantage of using the ThreadPool threads and getting async callbacks on them. But in my app, I'm the client and I just need to listen to one server sending market tick data over one tcp connection. Right now, I create a single thread, set the priority to Highest, and call Socket.Receive() with it. My thread blocks on this call and wakes up once new data arrives. If I were to switch this to an async pattern so that I get a callback when there's new data, I see two issues The threadpool threads will have default priority so it seems they will be strictly worse than my own thread which has Highest priority. I'll still have to send everything through a single thread at some point. Say that I get N callbacks at almost the same time on N different threadpool threads notifying me that there's new data. The N byte arrays that they deliver can't be processed on the threadpool threads because there's no guarantee that they represent N unique market data messages because TCP is stream based. I'll have to lock and put the bytes into an array anyway and signal some other thread that can process what's in the array. So I'm not sure what having N threadpool threads is buying me. Am I thinking about this wrong? Is there a reason to use the Async patter in my specific case of one client connected to one server?

• Async.Parallel or Array.Parallel.Map ?

  - by gurteen2

  Hello- I'm trying to implement a pattern I read from Don Syme's blog (http://blogs.msdn.com/dsyme/archive/2010/01/09/async-and-parallel-design-patterns-in-f-parallelizing-cpu-and-i-o-computations.aspx) which suggests that there are opportunities for massive performance improvements from leveraging asynchronous I/O. I am currently trying to take a piece of code that "works" one way, using Array.Parallel.Map, and see if I can somehow achieve the same result using Async.Parallel, but I really don't understand Async.Parallel, and cannot get anything to work. I have a piece of code (simplified below to illustrate the point) that successfully retrieves an array of data for one cusip. (A price series, for example) let getStockData cusip = let D = DataProvider() let arr = D.GetPriceSeries(cusip) return arr let data = Array.Parallel.map (fun x -> getStockData x) stockCusips So this approach contructs an array of arrays, by making a connection over the internet to my data vendor for each stock (which could be as many as 3000) and returns me an array of arrays (1 per stock, with a price series for each one). I admittedly don't understand what goes on underneath Array.Parallel.map, but am wondering if this is a scenario where there are resources wasted under the hood, and it actually could be faster using asynchronous I/O? So to test this out, I have attempted to make this function using asyncs, and I think that the function below follows the pattern in Don Syme's article using the URLs, but it won't compile with "let!". let getStockDataAsync cusip = async { let D = DataProvider() let! arr = D.GetData(cusip) return arr } The error I get is: This expression was expected to have type Async<'a but here has type obj It compiles fine with "let" instead of "let!", but I had thought the whole point was that you need the exclamation point in order for the command to run without blocking a thread. So the first question really is, what's wrong with my syntax above, in getStockDataAsync, and then at a higher level, can anyone offer some additional insight about asychronous I/O and whether the scenario I have presented would benefit from it, making it potentially much, much faster than Array.Parallel.map? Thanks so much.

• How to roll the log file on startup in logback

  - by Mike Q

  Hi all, I would like to configure logback to do the following. Log to a file Roll the file when it reaches 50MB Only keep 7 days worth of logs On startup always generate a new file (do a roll) I have it all working except for the last item, startup roll. Does anyone know how to achieve that? Here's the config... <appender name="File" class="ch.qos.logback.core.rolling.RollingFileAppender"> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg \(%file:%line\)%n</Pattern> </layout> <File>server.log</File> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>server.%d{yyyy-MM-dd}.log</FileNamePattern> <!-- keep 7 days' worth of history --> <MaxHistory>7</MaxHistory> <TimeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <MaxFileSize>50MB</MaxFileSize> </TimeBasedFileNamingAndTriggeringPolicy> </rollingPolicy> </appender>

• Help needed implementing a web based file management system with a file hierarchy system, help neede

  - by molleman

  Hello i am trying to create a web application that will allow users to upload files online, i am using gwt while using hibernate for database communication, i am able to upload file to a server , and store them on the server. but what i want is to associate the files with a user. i want the user to be able to create folders and store a file in sub folders. my logic was to use the composite pattern to store folders and fileLocations with a user but i am am finding it difficult to implement this so i can show the files and folders within a gwt tree. what would be the best way to implement a hierarchy of folders and information of the location of a file so it could be displayed in a gwt tree? what i did have was a User would hold a reference to a root folder and then each sub folder could hold folders or fileLocations. i used the composite pattern to implement the file hierarchy, but when i want to display a the contents of a folder i need a for loop for each list. so i could a folder within a folder within a folder that would need 3 for loops to show the contents of my folders. What is the best way to implement this file management system. so what do you guys think?

• Resources related to data-mining and gaming on social networks

  - by darren

  Hi all I'm interested in the problem of patterning mining among players of social networking games. For example detecting cheaters of a game, given a company's user database. So far I have been following the usual recipe for a data mining project: construct a data warehouse that aggregates significant information select a classifier, and train it with a subsectio of records from the warehouse validate classifier with another test set lather, rinse, repeat Surprisingly, I've found very little in this area regarding literature, best practices, etc. I am hoping to crowdsource the information gathering problem here. Specifically what I'm looking for: What classifiers have worked will for this type of pattern mining (it seems highly temporal, users playing games, users receiving rewards, users transferring prizes etc). Are there any highly agreed upon attributes specific to social networking / gaming data? What is a practical amount of information that should be considered? One problem I've run into is data overload, where queries and data cleansing may take days to complete. Related to point above, what hardware resources are required to produce results? I've found it difficult to estimate the amount of computing power I will require for production use. It has become apparent that a white box in the corner does not have enough horse-power for such a project. Are companies generally resorting to cloud solutions? Are they buying clusters? Basically, any resources (theoretical, academic, or practical) about implementing a social networking / gaming pattern-mining program would be very much appreciated. Thanks.

• AS3 : RegExp exec method in loop problem

  - by Boun

  Hi everyone, I need some help about RegExp in AS3. I have a simple pattern : patternYouTube = new RegExp ( "v(?:\/|=)([A-Z0-9_-]+)", "gi" ); This pattern is looking for the youTube id video. For example : var tmpUrl : String; var result : Object; var toto : Array = new Array(); toto = [http://www.youtube.com/v/J-vCxmjCm-8&autoplay=1, http://www.youtube.com/v/xFTRnE1WBmU&autoplay=1]; var i : uint; for ( i = 0 ; i < toto.length ; i++) { tmpUrl = toto[i]; result = patternYouTube.exec ( tmpUrl ); if ( result.length != 0 && result != null ) { trace(result); } } When i == 0, it works perfectly. Flash returns me : v/J-vCxmjCm-8,J-vCxmjCm-8 When i == 1, it fails. Flash returns me : null When I revert the two strings in my array such as : toto = [ http://www.youtube.com/v/xFTRnE1WBmU&autoplay=1, http://www.youtube.com/v/J-vCxmjCm-8&autoplay=1 ]; When i == 0, it works perfectly : Flash returns me : xFTRnE1WBmU When i == 1, it fails : Flash returns me : null Do you have any idea about the problem in the loop ?

• Need help modifying C++ application to accept continuous piped input in Linux

  - by GreeenGuru

  The goal is to mine packet headers for URLs visited using tcpdump. So far, I can save a packet header to a file using: tcpdump "dst port 80 and tcp[13] & 0x08 = 8" -A -s 300 | tee -a ./Desktop/packets.txt And I've written a program to parse through the header and extract the URL when given the following command: cat ~/Desktop/packets.txt | ./packet-parser.exe But what I want to be able to do is pipe tcpdump directly into my program, which will then log the data: tcpdump "dst port 80 and tcp[13] & 0x08 = 8" -A -s 300 | ./packet-parser.exe Here is the script as it is. The question is: how do I need to change it to support continuous input from tcpdump? #include <boost/regex.hpp> #include <fstream> #include <cstdio> // Needed to define ios::app #include <string> #include <iostream> int main() { // Make sure to open the file in append mode std::ofstream file_out("/var/local/GreeenLogger/url.log", std::ios::app); if (not file_out) std::perror("/var/local/GreeenLogger/url.log"); else { std::string text; // Get multiple lines of input -- raw std::getline(std::cin, text, '\0'); const boost::regex pattern("GET (\\S+) HTTP.*?[\\r\\n]+Host: (\\S+)"); boost::smatch match_object; bool match = boost::regex_search(text, match_object, pattern); if(match) { std::string output; output = match_object[2] + match_object[1]; file_out << output << '\n'; std::cout << output << std::endl; } file_out.close(); } } Thank you ahead of time for the help!

• Database structure - is mySQL the right choice?

  - by Industrial

  Hi everyone, We are currently planning the database structure of a quite complex e-commerce web app that has flexibility as it's main cornerstone. Our app features a large amount of data (products) and we have run into a slight headache trying to keep performance high without compromizing normalization rules in the database, or leaving our highly beloved flexibility concept behind when integrating product options (also widely known as product attributes or parameters). Based on various references and sources available, we have made up lists on pros and cons of all major and well known database patterns to solve this. After comparing these, we have come up with two final alternatives: EAV (Entity-attribute-value model) : Pros: Database is used for all sorting. Cons: All related queries will include a number of joins between multiple tables in order to complete the collection of data. SLOB (Serialized LOB, also known as Facade?) : Pros: Very flexible. Keeping the number of necessary joins low compared to a EAV design pattern. Easy to update/add/remove data from each product. Cons: All sorting will be done by the application instead of the database. Will use lots of performance (memory?) when big datasets is processed by a large number of users. Our main questions: Which pattern/structure would you use, or maybe even a different solution? Is there better databases besides mySQL available nowadays to accomplish what we want? Thanks a lot!

• How do you capture a group with regex?

  - by Sylvain

  Hi, I'm trying to extract a string from another using regex. I'm using the POSIX regex functions (regcomp, regexec ...), and I fail at capturing a group ... For instance, let the pattern be something as simple as "MAIL FROM:<(.*)>" (with REG_EXTENDED cflags) I want to capture everything between '<' and '' My problem is that regmatch_t gives me the boundaries of the whole pattern (MAIL FROM:<...) instead of just what's between the parenthesis ... What am I missing ? Thanks in advance, edit: some code #define SENDER_REGEX "MAIL FROM:<(.*)>" int main(int ac, char **av) { regex_t regex; int status; regmatch_t pmatch[1]; if (regcomp(&regex, SENDER_REGEX, REG_ICASE|REG_EXTENDED) != 0) printf("regcomp error\n"); status = regexec(&regex, av[1], 1, pmatch, 0); regfree(&regex); if (!status) printf( "matched from %d (%c) to %d (%c)\n" , pmatch[0].rm_so , av[1][pmatch[0].rm_so] , pmatch[0].rm_eo , av[1][pmatch[0].rm_eo] ); return (0); } outputs: $./a.out "012345MAIL FROM:<abcd>$" matched from 6 (M) to 22 ($) solution: as RarrRarrRarr said, the indices are indeed in pmatch[1].rm_so and pmatch[1].rm_eo hence regmatch_t pmatch[1]; becomes regmatch_t pmatch[2]; and regexec(&regex, av[1], 1, pmatch, 0); becomes regexec(&regex, av[1], 2, pmatch, 0); Thanks :)

• How to avoid using this in a contructor

  - by Paralife

  I have this situation: interface MessageListener { void onMessageReceipt(Message message); } class MessageReceiver { MessageListener listener; public MessageReceiver(MessageListener listener, other arguments...) { this.listener = listener; } loop() { Message message = nextMessage(); listener.onMessageReceipt(message); } } and I want to avoid the following pattern: (Using the this in the Client constructor) class Client implements MessageListener { MessageReceiver receiver; MessageSender sender; public Client(...) { receiver = new MessageReceiver(this, other arguments...); sender = new Sender(...); } . . . @Override public void onMessageReceipt(Message message) { if(Message.isGood()) sender.send("Congrtulations"); else sender.send("Boooooooo"); } } The reason why i need the above functionality is because i want to call the sender inside the onMessageReceipt() function, for example to send a reply. But I dont want to pass the sender into a listener, so the only way I can think of is containing the sender in a class that implements the listener, hence the above resulting Client implementation. Is there a way to achive this without the use of 'this' in the constructor? It feels bizare and i dont like it, since i am passing myself to an object(MessageReceiver) before I am fully constructed. On the other hand, the MessageReceiver is not passed from outside, it is constructed inside, but does this 'purifies' the bizarre pattern? I am seeking for an alternative or an assurance of some kind that this is safe, or situations on which it might backfire on me.

• Sync Vs. Async Sockets Performance in .NET

  - by Michael Covelli

  Everything that I read about sockets in .NET says that the asynchronous pattern gives better performance (especially with the new SocketAsyncEventArgs which saves on the allocation). I think this makes sense if we're talking about a server with many client connections where its not possible to allocate one thread per connection. Then I can see the advantage of using the ThreadPool threads and getting async callbacks on them. But in my app, I'm the client and I just need to listen to one server sending market tick data over one tcp connection. Right now, I create a single thread, set the priority to Highest, and call Socket.Receive() with it. My thread blocks on this call and wakes up once new data arrives. If I were to switch this to an async pattern so that I get a callback when there's new data, I see two issues The threadpool threads will have default priority so it seems they will be strictly worse than my own thread which has Highest priority. I'll still have to send everything through a single thread at some point. Say that I get N callbacks at almost the same time on N different threadpool threads notifying me that there's new data. The N byte arrays that they deliver can't be processed on the threadpool threads because there's no guarantee that they represent N unique market data messages because TCP is stream based. I'll have to lock and put the bytes into an array anyway and signal some other thread that can process what's in the array. So I'm not sure what having N threadpool threads is buying me. Am I thinking about this wrong? Is there a reason to use the Async patter in my specific case of one client connected to one server?

• java regex: capture multiline sequence between tokens

  - by Guillaume

  I'm struggling with regex for splitting logs files into log sequence in order to match pattern inside these sequences. log format is: timestamp fieldA fieldB fieldn log message1 timestamp fieldA fieldB fieldn log message2 log message2bis timestamp fieldA fieldB fieldn log message3 The timestamp regex is known. I want to extract every log sequence (potentialy multiline) between timestamps. And I want to keep the timestamp. I want in the same time to keep the exact count of lines. What I need is how to decorate timestamp pattern to make it split my log file in log sequence. I can not split the whole file as a String, since the file content is provided in a CharBuffer Here is sample method that will be using this log sequence matcher: private void matches(File f, CharBuffer cb) { Matcher sequenceBreak = sequencePattern.matcher(cb); // sequence matcher int lines = 1; int sequences = 0; while (sequenceBreak.find()) { sequences++; String sequence = sequenceBreak.group(); if (filter.accept(sequence)) { System.out.println(f + ":" + lines + ":" + sequence); } //count lines Matcher lineBreak = LINE_PATTERN.matcher(sequence); while (lineBreak.find()) { lines++; } if (sequenceBreak.end() == cb.limit()) { break; } } }

• Changing FileNames using RegEx and Recursion

  - by yeahumok

  Hello I'm trying to rename files that my program lists as having "illegal characters" for a SharePoint file importation. The illegal characters I am referring to are: ~ # % & * {} / \ | : < ? - "" What i'm trying to do is recurse through the drive, gather up a list of filenames and then through Regular Expressions, pick out file names from a List and try to replace the invalid characters in the actual filenames themselves. Anybody have any idea how to do this? So far i have this: (please remember, i'm a complete n00b to this stuff) class Program { static void Main(string[] args) { string[] files = Directory.GetFiles(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing", "*.*", SearchOption.AllDirectories); foreach (string file in files) { Console.Write(file + "\r\n"); } Console.WriteLine("Press any key to continue..."); Console.ReadKey(true); string pattern = " *[\\~#%&*{}/:<>?|\"-]+ *"; string replacement = " "; Regex regEx = new Regex(pattern); string[] fileDrive = Directory.GetFiles(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing", "*.*", SearchOption.AllDirectories); StreamWriter sw = new StreamWriter(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing\File_Renames.txt"); foreach(string fileNames in fileDrive) { string sanitized = regEx.Replace(fileNames, replacement); sw.Write(sanitized + "\r\n"); } sw.Close(); } } So what i need to figure out is how to recursively search for these invalid chars, replace them in the actual filename itself. Anybody have any ideas?
