  • How can I print lines that match a pattern in Perl?

    - by kivien
    Assuming the file.txt having just one sentence per line as follows:- John Depp is a great guy. He is very inteligent. He can do anything. Come and meet John Depp. The perl code is as follows:- open ( FILE, "file.txt" ) || die "can't open file!"; @lines = <FILE>; close (FILE); $string = "John Depp"; foreach $line (@lines) { if ($line =~ $string) { print "$line"; } } The output is going to be first and fourth line. I want to make it working for the file having random line breaks rather than one English sentence per line. I mean it should also work for the following:- John Depp is a great guy. He is very inteligent. He can do anything. Come and meet John Depp. The output should be first and fourth sentence. Any ideas please?

  • How to use Svn Version Task to set the Version of a vb project

    - by SchlaWiener
    I have a Visual Studio 2008 Solution where the main output exe is a VB.Net Winforms exe which has several VB.Net and C# dll's linked from the same solution. The whole solution is under version control with subversion. Now I want to automagically update by generated files with the current svn revision number. For this purpose I found this neat project: http://svnversiontasks.codeplex.com/ You also need the MSBuild.Communuity.Tasks for this to work. There was a msbuild example on how to update the rev number for every single project in your solution which I use: <Import Project="$(MSBuildExtensionsPath)\SvnTools.Targets\SvnTools.Tasks.VersionManagement.Tasks" /> <Target Name="build"> <CreateItem Include="../**/AssemblyInfo.vb;../**/AssemblyInfo.cs;../**/Properties/AssemblyInfo.cs"> <Output TaskParameter="Include" ItemName="AssemblyInfoFiles" /> </CreateItem> <CreateItem Include="../**/*.vdproj;*.vdproj"> <Output TaskParameter="Include" ItemName="DeploymentProjectFiles" /> </CreateItem> <UpdateVersion AssemblyInfoFiles="@(AssemblyInfoFiles)" DeploymentProjectFiles="@(DeploymentProjectFiles)" Format="yyyy.mm.dd.rev" /> <Exec Command="&quot;$(VS90COMNTOOLS)..\IDE\devenv&quot; ..\MyApp.sln /build" /> <RevertVersionChange AssemblyInfoFiles="@(AssemblyInfoFiles)" DeploymentProjectFiles="@(DeploymentProjectFiles)" /> </Target> I modified the original file to also include the AssemblyInfo.vb file and saved it as a msbuild.proj file. However if I execute msbuild from the console I see that the C# projects are updated (I can also confirm that from the properties of the output dll but my vb project remains unchanged: Reverting version number change: ../App1\AssemblyInfo.vb Updating version number (to rev 0) for file: ../App1\AssemblyInfo.vb D:\Source\MyApp\MyAppDeploy\MyAppDeploy.csproj : warning : Version attribute not found, file not updated. Reverting version number change: ../App2\Properties\AssemblyInfo.cs Updating version number (to rev 0) for file: ../App2\Properties\AssemblyInfo.cs Successfully updated file. Maybe the task does not support VB.Net. But maybe someone has a solution for this...

  • Error doing an MSBuild on a CLR Storedprocedure project on Build Server

    - by CraftyFella
    Hi, When building a CLR Storedprocedure Project using MSBuild on our build server (Team City) we're getting the following error: error MSB4019: The imported project "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\SqlServer.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk I've checked to see if the file exists on disk and sure enough it doesn't. I've checked on my own machine and it does exist. I don't really want to start copying over files manually to the build server. Here's the line from the csproj file which is being imported to the proj file: <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> <Import Project="$(MSBuildToolsPath)\SqlServer.targets" /> Here's the line from the proj file which is begin run by our Team City Server: <Import Project="..\$(ProjectName).csproj"/> My question is really: Where does this file comes from? Is it part of the Visual Studio install for example.. Or is there some re-distribution package somewhere to allow me to compile this project on our build server? Thanks BTW.. if i just copy the file onto the Build server it does actually work. Dave

  • Turning off hibernate logging console output

    I'm using hibernate 3 and want to stop it from dumping all the startup messages to the console. I tried commenting out the stdout lines in log4j.properties but no luck.

  • reactor not working when reactor.run is not called in the main thread and installSignalHandlers=Fals

    - by Kalmi
    I'm trying to answer the following question out of personal interest: What is the fastest way to send 100,000 HTTP requests in Python? And this is what I have came up so far, but I'm experiencing something very stange. When installSignalHandlers is True, it just hangs. I can see that the DelayedCall instances are in reactor._newTimedCalls, but processResponse never gets called. When installSignalHandlers is False, it throws an error and works. from twisted.internet import reactor from twisted.web.client import Agent from threading import Semaphore, Thread import time concurrent = 100 s = Semaphore(concurrent) reactor.suggestThreadPoolSize(concurrent) t=Thread( target=reactor.run, kwargs={'installSignalHandlers':True}) t.daemon=True t.start() agent = Agent(reactor) def processResponse(response,url): print response.code, url s.release() def processError(response,url): print "error", url s.release() def addTask(url): req = agent.request('HEAD', url) req.addCallback(processResponse, url) req.addErrback(processError, url) for url in open('urllist.txt'): addTask(url.strip()) s.acquire() while s._Semaphore__value!=concurrent: time.sleep(0.1) reactor.stop() And here is the error that it throws when installSignalHandlers is True: (Note: This is the expected behaviour! The question is why it doesn't work when installSignalHandlers is False.)

  • Python MD5 Hash Faster Calculation

    - by balgan
    Hi everyone. I will try my best to explain my problem and my line of thought on how I think I can solve it. I use this code for root, dirs, files in os.walk(downloaddir): for infile in files: f = open(os.path.join(root,infile),'rb') filehash = hashlib.md5() while True: data = f.read(10240) if len(data) == 0: break filehash.update(data) print "FILENAME: " , infile print "FILE HASH: " , filehash.hexdigest() and using start = time.time() elapsed = time.time() - start I measure how long it takes to calculate an hash. Pointing my code to a file with 653megs this is the result: root@Mars:/home/tiago# python algorithm-timer.py FILENAME: freebsd.iso FILE HASH: ace0afedfa7c6e0ad12c77b6652b02ab 12.624 root@Mars:/home/tiago# python algorithm-timer.py FILENAME: freebsd.iso FILE HASH: ace0afedfa7c6e0ad12c77b6652b02ab 12.373 root@Mars:/home/tiago# python algorithm-timer.py FILENAME: freebsd.iso FILE HASH: ace0afedfa7c6e0ad12c77b6652b02ab 12.540 Ok now 12 seconds +- on a 653mb file, my problem is I intend to use this code on a program that will run through multiple files, some of them might be 4/5/6Gb and it will take wayy longer to calculate. What am wondering is if there is a faster way for me to calculate the hash of the file? Maybe by doing some multithreading? I used a another script to check the use of the CPU second by second and I see that my code is only using 1 out of my 2 CPUs and only at 25% max, any way I can change this? Thank you all in advance for the given help.

  • Getting nice sound from Java

    - by Peter Lang
    I managed to play midi files using Java, but it produces some distracting noise. I figured out that this is caused by the poor quality soundbank file shipped with Java 6 SDK/JRE. How can I improve that quality? Here is what I have so far: MidiNote example using a Receiver works fine (sounds the same as when playing midi files with other players), so it does not seem to use the Soundbank shipped with Java but the fallback mechanism that uses a hardware MIDI port. Using SimpleMidiPlayer example to play a Midi file works, but the quality is poor. When I delete lib/audio/soundbank.gm, the quality is not bad any more, so the fallback is used again. When I put soundbank-deluxe.gm into the same directory, it is used and produces much better sound. Messing with the clients soundbank file as described in the official Installation Instructions certainly isn't an option, so I tried to put the new soundbank-file into the jar-file and load it: Soundbank soundbank = MidiSystem.getSoundbank( getClass().getResourceAsStream("soundbank-deluxe.gm")); if(synthesizer.isSoundbankSupported(soundbank)) { System.out.println(synthesizer.loadAllInstruments(soundbank)); } This prints true, but the sound remains unchanged. What am I doing wrong loading the soundbank file? Can I force the hardware MIDI port to be used instead of the standard soundbank file?

  • Status Code from FTPWebRequest GetResponse method

    - by nick
    This is slightly tricky. I am uploading files to FTP asynchronously. After uploading each file I am checking the status of the upload operation for that file. This can be done with StatusCode property of the FtpWebResponse object for that request. The code snippet is as give below. System.IO.FileStream fs = System.IO.File.Open(fileName, System.IO.FileMode.Open); while ((iWork = fs.Read(buf, 0, buf.Length)) > 0) requestStream.Write(buf, 0, iWork); requestStream.Close(); FtpWebResponse wrRet = ((FtpWebResponse)state.Request.GetResponse()); There are about 37 StatusCode values as per msdn. I am unaware as to which of these status code values will assure that the file is uploaded successfully. Some of them I used in my code to check for success are : wrRet.StatusCode == FtpStatusCode.CommandOK wrRet.StatusCode == FtpStatusCode.ClosingData wrRet.StatusCode == FtpStatusCode.ClosingControl wrRet.StatusCode == FtpStatusCode.ConnectionClosed wrRet.StatusCode == FtpStatusCode.FileActionOK wrRet.StatusCode == FtpStatusCode.FileStatus But I am unaware of the rest. I need to be sure about these codes because based on the failure or success of the upload operation I have other dependant operations to be carried out. A wrong condition can affect the remaining code. Another thought that crossed my mind was to simply put the above code into a try..catch and not depend on these status codes. With this I would not be depending on the status codes and assuming that any failure will always be directed to the catch block. Kindly let me know if this is the right way. Thanks in advance.

  • How do I escape ampersands in batch files?

    - by Peter Mortensen
    How do I escape ampersands in a batch file (or from the Windows command line) in order to use the start command to open web pages with ampersands in the URL? Double quotes will not work with start; this starts a new command line window instead. Update 1: Wael Dalloul's solution works. In addition, if there are URL encoded characters (e.g. space is encoded as %20) in the URL and it is in a batch file then '%' must be encoded as '%%'. This is not the case in the example. Example, from the command line (CMD.EXE): start http://www.google.com/search?client=opera&rls=en&q=escape+ampersand&sourceid=opera&ie=utf-8&oe=utf-8 will result in http://www.google.com/search?client=opera being opened in the default browser and these errors in the command line window: 'rls' is not recognized as an internal or external command, operable program or batch file. 'q' is not recognized as an internal or external command, operable program or batch file. 'sourceid' is not recognized as an internal or external command, operable program or batch file. 'ie' is not recognized as an internal or external command, operable program or batch file. 'oe' is not recognized as an internal or external command, operable program or batch file.

  • Apache mod_rewrite RewriteCond to by-pass static resources not working

    - by d11wtq
    I can't for the life of me fathom out why this RewriteCond is causing every request to be sent to my FastCGI application when it should in fact be letting Apache serve up the static resources. I've added a hello.txt file to my DocumentRoot to demonstrate. The text file: ls /Sites/CioccolataTest.webapp/Contents/Resources/static hello.txt` The VirtualHost and it's rewrite rules: AppClass /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest -port 5065 FastCgiExternalServer /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest.fcgi -host 127.0.0.1:5065 <VirtualHost *:80> ServerName cioccolata-test.webdev DocumentRoot /Sites/CioccolataTest.webapp/Contents/Resources/static RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest.fcgi/$1 [QSA,L] </VirtualHost> Even with the -f, Apache is directing requests for this text file (i.e. access http://cioccolata-test.webdev/hello.txt returns my app, not the text file). As a proof of concept I changed the RewriteCond to: RewriteCond %{REQUEST_URI} !^/hello.txt That made it serve the text file correctly and allowed every other request to hit the FastCGI application. Why doesn't my original version work? I need to tell apache to serve every file in the DocumentRoot as a static resource, but if the file doesn't exist it should rewrite the request to my FastCGI application. NOTE: The running FastCGI application is at /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest (without the .fcgi prefix)... the .fcgi prefix is only being used to tell the fastcgi module to direct the request to the app.

  • Practices for keeping JavaScript and CSS in sync?

    - by Rene Saarsoo
    I'm working on a large JavaScript-heavy app. Several pieces of JavaScript have some related CSS rules. Our current practice is for each JavaScript file to have an optional related CSS file, like so: MyComponent.js // Adds CSS class "my-comp" to div MyComponent.css // Defines .my-comp { color: green } This way I know that all CSS related to MyComponent.js will be in MyComponent.css. But the thing is, I all too often have very little CSS in those files. And all too often I feel that it's too much effort to create a whole file to just contain few lines of CSS - it would be easier to just hardcode the styles inside JavaScript. But this would be the path to the dark side... Lately I've been thinking of embedding the CSS directly inside JavaScript - so it could still be extracted in the build process and merged into one large CSS file. This way I wouldn't have to create a new file for every little CSS-piece. Additionally when I move/rename/delete the JavaScript file I don't have to additionally move/rename/delete the CSS file. But how to embed CSS inside JavaScript? In most other languages I would just use string, but JavaScript has some issues with multiline strings. The following looks IMHO quite ugly: Page.addCSS("\ .my-comp > p {\ font-weight: bold;\ color: green;\ }\ "); What other practices have you for keeping your JavaScript and CSS in sync?

  • On Windows 7: Same path but Explorer & Java see different files than Powershell

    - by Ukko
    Submitted for your approval, a story about a poor little java process trapped in the twilight zone... Before I throw up my hands and just say that the NTFS partition is borked is there any rational explanation of what I am seeing. I have a file with a path like this C:\Program Files\Company\product\config\file.xml I am reading this file after an upgrade and seeing something wonky. Eclipse and my Java app are still seeing the old version of this file while some other programs see the new version. The test that convinced my it was not my fat finger that caused the problem was this: In Explorer I entered the above path and Explorer displayed the old version of the file. Forcing Explorer to reload via Ctrl-F5 still yields the old version. This is the behavior I get in Java. Now in PowerShell I enter more "C:\Program Files\Company\product\config\file.xml" I cut and past the path from Explorer to make sure I am not screwing anything up and it shows me the new version of the file. So for the programming aspect of this, is there a cache or some system component that would be storing this stale reference. Am I responsible for checking or reseting that for some class of files. I can imagine somebody being "creative" in how xml files are processed to provide some bell or whistle. But it could be a case of just being borked. Any insights appreciated...Thanks!

  • Replacing unversioned files in WiX major upgrade.

    - by Joshua
    I am still having this problem. This is the closest I have come to a solution that works, and yet it doesn't quite work. Here is (most of) the code: <Product Id='$(var.ProductCode)' UpgradeCode='$(var.UpgradeCode)' Name="Pathways" Version='$(var.ProductVersion)' Manufacturer='$(var.Manufacturer)' Language='1033'> Maximum="$(var.ProductVersion)" IncludeMaximum="no" Language="1033" Property="OLDAPPFOUND" / -- -- -- There is a later version of this program installed. The problem I am having is that I need the two files in the Database component to replace the previous copies. Since these files are unversioned, I have attempted to use the CompanionFile tag set to the PathwaysExe since that is the main executable of the application, and it IS being updated, even if the log says it isn't! The strangest thing about this is that the PathwaysLdf file IS BEING UPDATED CORRECTLY, and the PathwaysMdf file IS NOT. The log seems to indicate that the "Existing file is of an equal version (Checked using version of companion)". This is very strange because that file is being replaced just fine. The only idea I have left is that this problem has to do with the install sequence, and I'm not sure how to proceed! I have the InstallExecuteSequence set like I do because of the SettingsXml file, and my need to NOT overwrite that file, which is actually working now, so whatever solution works for the database files can't break the working settings file! ;) The full log is located at: http://pastebin.com/HFiGKuKN PLEASE AND THANK YOU!

  • HTTP crawler in Erlang

    I'm coding on a simple HTTP crawler but I have an issue running the code at the bottom. I'm requesting 50 URLs and get the content of 20+ back. I've generated few files with 150kB size each to test the crawler. So I think the 20+ responses are limited by the bandwidth? BUT: how to tell the Erlang snippet not to quit until the last file is not fetched? The test data server is online, so plz try the code out and any hints are welcome :) -module(crawler). -define(BASE_URL, "http://46.4.117.69/"). -export([start/0, send_reqs/0, do_send_req/1]). start() -> ibrowse:start(), proc_lib:spawn(?MODULE, send_reqs, []). to_url(Id) -> ?BASE_URL ++ integer_to_list(Id). fetch_ids() -> lists:seq(1, 50). send_reqs() -> spawn_workers(fetch_ids()). spawn_workers(Ids) -> lists:foreach(fun do_spawn/1, Ids). do_spawn(Id) -> proc_lib:spawn_link(?MODULE, do_send_req, [Id]). do_send_req(Id) -> io:format("Requesting ID ~p ... ~n", [Id]), Result = (catch ibrowse:send_req(to_url(Id), [], get, [], [], 10000)), case Result of {ok, Status, _H, B} -> io:format("OK -- ID: ~2..0w -- Status: ~p -- Content length: ~p~n", [Id, Status, length(B)]); Err -> io:format("ERROR -- ID: ~p -- Error: ~p~n", [Id, Err]) end.

  • Multithreaded IOCP Client Issue

    - by Carl
    I am writing a multithreaded client that uses an IO Completion Port. I create and connect the socket that has the WSA_FLAG_OVERLAPPED attribute set. if ((m_socket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)) == INVALID_SOCKET) { throw std::exception("Failed to create socket."); } if (WSAConnectByName(m_socket, L"server.com", L"80", &localAddressLength, reinterpret_cast<sockaddr*>(&localAddress), &remoteAddressLength, &remoteAddress, NULL, NULL) == FALSE) { throw std::exception("Failed to connect."); } I associate the IO Completion Port with the socket. if ((m_hIOCP = CreateIoCompletionPort(reinterpret_cast<HANDLE>(m_socket), m_hIOCP, NULL, 8)) == NULL) { throw std::exception("Failed to create IOCP object."); } All appears to go well until I try to send some data over the socket. SocketData* socketData = new SocketData; socketData->hEvent = 0; DWORD bytesSent = 0; if (WSASend(m_socket, socketData->SetBuffer(socketData->GenerateLoginRequestHeader()), 1, &bytesSent, NULL, reinterpret_cast<OVERLAPPED*>(socketData), NULL) == SOCKET_ERROR && WSAGetLastError() != WSA_IO_PENDING) { throw std::exception("Failed to send data."); } Instead of returning SOCKET_ERROR with the last error set to WSA_IO_PENDING, WSASend returns immediately. I need the IO to pend and for it's completion to be handled in my thread function which is also my worker thread. unsigned int __stdcall MyClass::WorkerThread(void* lpThis) { } I've done this before but I don't know what is going wrong in this case, I'd greatly appreciate any efforts in helping me fix this problem.
