  • two log4j files for EAR with two modules

    - by nicktmro
    Hi, I have an EAR that is made up of two modules. Both expose services and share common code. Imagine that the ear has a common.jar shared by a webservices.war and webapp.war. I use log4j to log the activities. I would like to be able to have two log files (webservices.log and webapp.log) capturing the events that are specific to each of them plus all the stuff that is handled by the common.jar. How should I configure my categories and my appenders to achieve this? At the moment I have the following packages: com.myapp for shared stuff com.myapp.webservices for the webservices and com.myapp.webapp for the webapp. My problem is that I don't know how I can capture the com.myapp (common stuff) in both log files by using a single log4j configuration file. I have tried setting up multiple configuration files but when JBoss would work OK Websphere would break and the other way round... Thank you

  • Sending compres data via socket

    - by Pizza
    Hi, I have to make a log server in java, and one task is to send the data compressed. Now I am sending it line by line in plain text, but I must compress it. The server handle "HTTP like" request. For example, I can get a log sending "GET xxx.log". This will entablish a TCP connection to the server, the server response with a header and the log, and close the connection. The client, reads line by line and analyzes each LOG entry. I tried some ways without success. My main problem is that I don't know where each line ends(in the client size). Any idea?

    - by Stefano Maglione
    i'm fetching a collection but i've problem because into the collection the function parse use an another ajax call.So if i try to console.log the response of fetch after the fetch linecode but it is ever undefined. Function call fetch: friends: function(){ var amici=new Amicizie(); var amicilist=amici.fetch(); console.log(amicilist);<---undefined,because executed before fetch collection called: var obj={}; var Amicizie = Backbone.Collection.extend({ url:'https://api.parse.com/1/classes/User/', parse: function(data) { var cur_user=Parse.User.current().id; $.ajax({ type: 'GET', headers: {'X-Parse-Application-Id':'qS0KL***EM1tyhM9EEPiTS3VMk','X-Parse-REST-API- Key':'nh3eoUo9G***JIfIt1Gm'}, url: "https://api.parse.com/1/classes/_User/?where=....", success: function(object) { console.log(object ); obj=object; console.log(obj ); }, error: function(data) { console.log("ko" ); } }); return obj.results; } }); return Amicizie; });

  • How to inhibit suspend temporarily?

    - by Zorn
    I have searched around a bit for this and can't seem to find anything helpful. I have my PC running Ubuntu 12.10 set up to suspend after 30 minutes of inactivity. I don't want to change that, it works great most of the time. What I do want to do is disable the automatic suspend if a particular application is running. How can I do this? The closest thing I've found so far is to add a shell script in /usr/lib/pm-utils/sleep.d which checks if the application is running and returns 1 to indicate that suspend should be prevented. But it looks like the system then gives up on suspending automatically, instead of trying again after another 30 minutes. (As far as I can tell, if I move the mouse, that restarts the timer again.) It's quite likely the application will finish after a couple of hours, and I'd rather my PC then suspended automatically if I'm not using it at that point. (So I don't want to add a call to pm-suspend when the application finishes.) Is this possible? Any advice would be appreciated. Cheers. EDIT: As I noted in one of the comments below, what I actually wanted was to inhibit suspend when my PC was serving files over NFS; I just wanted to focus on the "suspend" part of the question because I already had an idea how to solve the NFS part. Using the 'xdotool' idea given in one of the answers, I have come up with the following script which I run from cron every few minutes. It's not ideal because it stops the screensaver kicking in as well, but it does work. I need to have a look at why 'caffeine' doesn't correctly re-enable suspend later on, then I could probably do better. Anyway, this does seem to work, so I'm including it here in case anyone else is interested. #!/bin/bash # If the output of this function changes between two successive runs of this # script, we inhibit auto-suspend. function check_activity() { /usr/sbin/nfsstat --server --list } # Prevent the automatic suspend from kicking in. function inhibit_suspend() { # Slightly jiggle the mouse pointer about; we do a small step and # reverse step to try to stop this being annoying to anyone using the # PC. TODO: This isn't ideal, apart from being a bit hacky it stops # the screensaver kicking in as well, when all we want is to stop # the PC suspending. Can 'caffeine' help? export DISPLAY=:0.0 xdotool mousemove_relative --sync -- 1 1 xdotool mousemove_relative --sync -- -1 -1 } LOG="$HOME/log/nfs-suspend-blocker.log" ACTIVITYFILE1="$HOME/tmp/nfs-suspend-blocker.current" ACTIVITYFILE2="$HOME/tmp/nfs-suspend-blocker.previous" echo "Started run at $(date)" >> "$LOG" if [ ! -f "$ACTIVITYFILE1" ]; then check_activity > "$ACTIVITYFILE1" exit 0; fi /bin/mv "$ACTIVITYFILE1" "$ACTIVITYFILE2" check_activity > "$ACTIVITYFILE1" if cmp --quiet "$ACTIVITYFILE1" "$ACTIVITYFILE2"; then echo "No activity detected since last run" >> "$LOG" else echo "Activity detected since last run; inhibiting suspend" >> "$LOG" inhibit_suspend fi

  • Apache virtual host does not work properly

    - by Jori
    I have read a lot of information all over the Internet regarding this subject, and can not figure out what I'am doing wrong. I'm trying to host two websites under different names locally under Windows 7 with Apaches Virtual Hosting functionality. This is what I have done already: In the httpd.conf file I uncommented the following line, so that the virtual host configuration file will be included in the main configuration sequence. # Virtual hosts Include conf/extra/httpd-vhosts.conf This is how I edited my httpd-vhosts.conf: # # Virtual Hosts # # If you want to maintain multiple domains/hostnames on your # machine you can setup VirtualHost containers for them. Most configurations # use only name-based virtual hosts so the server doesn't need to worry about # IP addresses. This is indicated by the asterisks in the directives below. # # Please see the documentation at # <URL:http://httpd.apache.org/docs/2.2/vhosts/> # for further details before you try to setup virtual hosts. # # You may use the command line option '-S' to verify your virtual host # configuration. # # Use name-based virtual hosting. # NameVirtualHost *:80 # # VirtualHost example: # Almost any Apache directive may go into a VirtualHost container. # The first VirtualHost section is used for all requests that do not # match a ServerName or ServerAlias in any <VirtualHost> block. # #<VirtualHost *:80> # ServerAdmin [email protected] # DocumentRoot "C:/apache/docs/dummy-host.localhost" # ServerName dummy-host.localhost # ServerAlias www.dummy-host.localhost # ErrorLog "logs/dummy-host.localhost-error.log" # CustomLog "logs/dummy-host.localhost-access.log" common #</VirtualHost> # #<VirtualHost *:80> # ServerAdmin [email protected] # DocumentRoot "C:/apache/docs/dummy-host2.localhost" # ServerName dummy-host2.localhost # ErrorLog "logs/dummy-host2.localhost-error.log" # CustomLog "logs/dummy-host2.localhost-access.log" common #</VirtualHost> <VirtualHost *:80> ServerName arterieur DocumentRoot "J:/webcontent/www20" <Directory "J:/webcontent/www20"> Order allow,deny Allow from all </Directory> </VirtualHost> As you can see I commented the Virtual Host examples out and added my own one (I did one for this example). Also am I sure that J:\webcontent\www20 exists. At last I edited the Windows host file located in: C:\Windows\System32\drivers\etc\hosts, now it looks this: # Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host # localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost 127.0.0.1 arterieur Then I restarted Apache with the Apache Service Monitor, and it gave me the following fatal error: The requested operation has failed!, I tried to look at the apache/logs/error.log file but I did not log anything, I guess it only logs the errors after startup. Does anyone knows what I'am doing wrong?

  • JDK 7u25: Solutions to Issues caused by changes to Runtime.exec

    - by Devika Gollapudi
    The following examples were prepared by Java engineering for the benefit of Java developers who may have faced issues with Runtime.exec on the Windows platform. Background In JDK 7u21, the decoding of command strings specified to Runtime.exec(String), Runtime.exec(String,String[]) and Runtime.exec(String,String[],File) methods, has been made more strict. See JDK 7u21 Release Notes for more information. This caused several issues for applications. The following section describes some of the problems faced by developers and their solutions. Note: In JDK 7u25, the system property jdk.lang.Process.allowAmbigousCommands can be used to relax the checking process and helps as a workaround for some applications that cannot be changed. The workaround is only effective for applications that are run without a SecurityManager. See JDK 7u25 Release Notes for more information. Note: To understand the details of the Windows API CreateProcess call, see: http://msdn.microsoft.com/en-us/library/windows/desktop/ms682425%28v=vs.85%29.aspx There are two forms of Runtime.exec calls: with the command as string: "Runtime.exec(String command[, ...])" with the command as string array: "Runtime.exec(String[] cmdarray [, ...] )" The issues described in this section relate to the first form of call. With the first call form, developers expect the command to be passed "as is" to Windows where the command needs be split into its executable name and arguments parts first. But, in accordance with Java API, the command argument is split into executable name and arguments by spaces. Problem 1: "The file path for the command includes spaces" In the call: Runtime.getRuntime().exec("c:\\Program Files\\do.exe") the argument is split by spaces to an array of strings as: c:\\Program, Files\\do.exe The first element of parsed array is interpreted as the executable name, verified by SecurityManager (if present) and surrounded by quotations to avoid ambiguity in executable path. This results in the wrong command: "c:\\Program" "Files\\do.exe" which will fail. Solution: Use the ProcessBuilder class, or the Runtime.exec(String[] cmdarray [, ...] ) call, or quote the executable path. Where it is not possible to change the application code and where a SecurityManager is not used, the Java property jdk.lang.Process.allowAmbigousCommands could be used by setting its value to "true" from the command line: -Djdk.lang.Process.allowAmbigousCommands=true This will relax the checking process to allow ambiguous input. Examples: new ProcessBuilder("c:\\Program Files\\do.exe").start() Runtime.getRuntime().exec(new String[]{"c:\\Program Files\\do.exe"}) Runtime.getRuntime().exec("\"c:\\Program Files\\do.exe\"") Problem 2: "Shell command/.bat/.cmd IO redirection" The following implicit cmd.exe calls: Runtime.getRuntime().exec("dir temp.txt") new ProcessBuilder("foo.bat", "", "temp.txt").start() Runtime.getRuntime().exec(new String[]{"foo.cmd", "", "temp.txt"}) lead to the wrong command: "XXXX" "" temp.txt Solution: To specify the command correctly, use the following options: Runtime.getRuntime().exec("cmd /C \"dir temp.txt\"") new ProcessBuilder("cmd", "/C", "foo.bat temp.txt").start() Runtime.getRuntime().exec(new String[]{"cmd", "/C", "foo.cmd temp.txt"}) or Process p = new ProcessBuilder("cmd", "/C" "XXX").redirectOutput(new File("temp.txt")).start(); Problem 3: "Group execution of shell command and/or .bat/.cmd files" Due to enforced verification procedure, arguments in the following calls create the wrong commands.: Runtime.getRuntime().exec("first.bat && second.bat") new ProcessBuilder("dir", "&&", "second.bat").start() Runtime.getRuntime().exec(new String[]{"dir", "|", "more"}) Solution: To specify the command correctly, use the following options: Runtime.exec("cmd /C \"first.bat && second.bat\"") new ProcessBuilder("cmd", "/C", "dir && second.bat").start() Runtime.exec(new String[]{"cmd", "/C", "dir | more"}) The same scenario also works for the "&", "||", "^" operators of the cmd.exe shell. Problem 4: ".bat/.cmd with special DOS chars in quoted params” Due to enforced verification, arguments in the following calls will cause exceptions to be thrown.: Runtime.getRuntime().exec("log.bat \"error new ProcessBuilder("log.bat", "error Runtime.getRuntime().exec(new String[]{"log.bat", "error Solution: To specify the command correctly, use the following options: Runtime.getRuntime().exec("cmd /C log.bat \"error new ProcessBuilder("cmd", "/C", "log.bat", "error Runtime.getRuntime().exec(new String[]{"cmd", "/C", "log.bat", "error Examples: Complicated redirection for shell construction: cmd /c dir /b C:\ "my lovely spaces.txt" becomes Runtime.getRuntime().exec(new String[]{"cmd", "/C", "dir \b \"my lovely spaces.txt\"" }); The Golden Rule: In most cases, cmd.exe has two arguments: "/C" and the command for interpretation.

  • MySQL Enterprise Backup 3.8.2 has been released!

    - by Hema Sridharan
    MySQL Enterprise Backup v3.8.2, a maintenance release of online MySQL backup tool, is now available for download from My Oracle Support  (MOS) website as our latest GA release.  It will also be available via the Oracle Software Delivery Cloud in approximately 1-2 weeks. A brief summary of the changes in MySQL Enterprise Backup version 3.8.2 is given below.   A. Functionality Added or Changed:  MySQL Enterprise Backup has a new --on-disk-full command line option. mysqlbackup could hang when the disk became full, rather than detecting the low space condition. mysqlbackup now monitors disk space when running backup commands, and users can now specify the action to take at a disk-full condition with the --on-disk-full option. For more details, refer this page MySQL Enterprise Backup has a new progress report feature, which periodically outputs short progress indicators on its  operations to user-selected destinations (for example, stdout, stderr, a file, or other choices). For more details on progress report options, refer here   B. Bugs Fixed: When --innodb-file-per-table=ON, if a table was renamed and backup-to-image was in progress, apply-log would fail when being run on the backup. (Bug #16903973)   MySQL Server failed to start after a backup was restored if  there had been online DDL transactions on partitioned tables during the time of backup. (Bug #16924499)   apply-log failed if ALTER TABLE ... REORGANIZE PARTITION was applied to partitioned InnoDB tables during backup. (Bug #16721824, Bug #16903951)  apply-incremental-backup might fail with an assertion error if  the InnoDB tables being backed up were created in Barracuda format and with their KEY_BLOCK_SIZE  values  different from the innodb_page_size . This fix ensures that different KEY_BLOCK_SIZE  values are handled properly during incremental backup and apply-incremental-backup operations.  If a table was renamed following a full backup, a subsequent incremental backup could copy the .frm file with the new name, but not the associated .ibd file with the new name. After a  restore, the InnoDB data dictionary could be in an  inconsistent state. This issue primarily occurred if the table  was not changed between the full backup and the subsequent  incremental backup. Bug #16262690)  After a full backup, if a table was renamed and modified,  apply-incremental-backup would crash when run on the backup directory. (Bug #16262609) The value of the binary log position in backup_variables.txt  could be different from the output displayed during the   backup-and-apply-log operation. (This issue did not occur if  the backup and apply-log steps were done separately.) (Bug  #16195529) When using the --only-innodb-with-frm option, MySQL Enterprise Backup tried to create temporary files at unintended locations in the file system, which might cause a failure when, for example, the user had no write privilege for those locations.   This fix makes sure the paths for the temporary files are  correct. (Bug #14787324)  A backup process might hang when it ran into an LSN mismatch between a data file  and the redo log. This fix makes sure the process does not hang and it displays an error message showing the  name of the problematic data file (Bug #14791645) Please post your questions / comments about Backup in forums. Thanks, MEB Team

    I'm getting the following error while testing my EHAB implementation: {"Activation error occured while trying to get instance of type ExceptionPolicyImpl, key "LogPolicy""} System.Exception Stack Trace: StackTrace " at Microsoft.Practices.ServiceLocation.ServiceLocatorImplBase.GetInstance(Type serviceType, String key) in c:\Home\Chris\Projects\CommonServiceLocator\main\Microsoft.Practices.ServiceLocation\ServiceLocatorImplBase.cs:line 53 at Microsoft.Practices.ServiceLocation.ServiceLocatorImplBase.GetInstance[TService](String key) in c:\Home\Chris\Projects\CommonServiceLocator\main\Microsoft.Practices.ServiceLocation\ServiceLocatorImplBase.cs:line 103 at Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ExceptionPolicy.GetExceptionPolicy(Exception exception, String policyName) in e:\Builds\EntLib\Latest\Source\Blocks\ExceptionHandling\Src\ExceptionHandling\ExceptionPolicy.cs:line 131 at Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ExceptionPolicy.HandleException(Exception exceptionToHandle, String policyName) in e:\Builds\EntLib\Latest\Source\Blocks\ExceptionHandling\Src\ExceptionHandling\ExceptionPolicy.cs:line 55 at Blackbox.Exception.ExceptionMain.LogException(Exception pException) in C:_Work_Black Box\Blackbox.Exception\ExceptionMain.vb:line 14 at BlackBox.Business.BusinessMain.TestExceptionHandling() in C:_Work_Black Box\BlackBox.Business\BusinessMain.vb:line 16 at Blackbox.Service.Service1.TestExceptionHandling() in C:_Work_Black Box\Blackbox.Service\Service.svc.vb:line 43" String Inner Exception: InnerException {"Resolution of the dependency failed, type = "Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ExceptionPolicyImpl", name = "LogPolicy".

  • PHPUnit XDebug required

    - by poru
    Hello, I finished installation of PHPUnit, it works but I don't get a code coverage report. I'm working on windows. My phpunit.xml <phpunit bootstrap="./application/bootstrap.php" colors="false"> <testsuite name="Application"> <directory>./</directory> </testsuite> <filter> <whitelist> <directory suffix=".php">./application</directory> <directory suffix=".php">./library/Application</directory> <exclude> <directory suffix=".php">../application/libraries/Zend</directory> <directory suffix=".php">../application/controllers</directory> <directory suffix=".phtml">./application/</directory> <file>./application/Bootstrap.php</file> </exclude> </whitelist> </filter> <logging> <log type="coverage-html" target="./log/report" charset="UTF-8" yui="true" highlight="true" lowUpperBound="50" highLowerBound="80" /> <log type="testdox" target="./log/testdox.html" /> </logging> If I run on cmd phpunit --configuration phpunit.xml it works so far, but PHPUnit doesn't create a code coverage report. If I run phpunit --configuration phpunit.xml --coverage-html \log or phpunit --configuration phpunit.xml --coverage-html log I get the error The Xdebug extension is not loaded. But I installed it (version 2.0.5)! phpinfo() says I installed it, also var_dump(extension_loaded('xdebug')) I get true. I installed it as Zend Extension and I tried also as normal extension. Bot worked, but PHPUnit says everytime Xdebug is not loaded!

  • Sphinx PHP Geodist problems

    - by James
    Below is my PHP function to call nearby points using Sphinx for MySQL. There are hundreds of thousands of nearby points which to what I can tell, are being indexed by Sphinx, but simply fails silently when searching with Sphinx. Other Sphinx queries I run against other indexes work completely fine. function nearby($latitude, $longitude, $radius) { global $sphinx; $sphinx->SetMatchMode(SPH_MATCH_ALL); $sphinx->SetArrayResult(true); $sphinx->SetLimits(0, 1000); $sphinx->SetGeoAnchor('latitude', 'longitude', (float) deg2rad($latitude), (float) deg2rad($longitude)); $circle = (float) $radius * 1.609344; $sphinx->SetFilterFloatRange('@geodist', 0.0, $circle); $matches = $sphinx->Query('', 'geo'); return $matches; } $nearby = nearby($latitude, $longitude, 10000); var_dump($nearby); This, when called with valid latitude and longitude co-ords and a very large radius for debugging produces: bool(false) Below is my sphinx.conf covering the geo part: source geo { type = mysql sql_host = 127.0.0.1 sql_user = user sql_pass = pass sql_db = db sql_port = 3306 sql_query_pre = set names utf8 sql_query_pre = set session query_cache_type=OFF sql_query = SELECT id,city,region,country,radians(longitude) AS longitude, radians(latitude) AS latitude FROM points; sql_attr_float = longitude sql_attr_float = latitude sql_ranged_throttle = 0 sql_query_info = SELECT * FROM points WHERE id = $id } index geo { source = geo path = /var/data/geo docinfo = extern #mlock = 0 #morphology = none min_word_len = 1 charset_type = utf-8 #charset_table = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F ignore_chars = U+00AD html_strip = 0 enable_star = 0 } indexer { mem_limit = 1024M } searchd { port = 3312 log = /var/log/searchd.log query_log = /var/log/query.log read_timeout = 5 max_children = 5 pid_file = /var/log/searchd.pid max_matches = 10000 seamless_rotate = 1 preopen_indexes = 0 unlink_old = 1 }

  • How can I effectively test a scripting engine?

    - by ChaosPandion
    I have been working on an ECMAScript implementation and I am currently working on polishing up the project. As a part of this, I have been writing tests like the following: [TestMethod] public void ArrayReduceTest() { var engine = new Engine(); var request = new ExecScriptRequest(@" var a = [1, 2, 3, 4, 5]; a.reduce(function(p, c, i, o) { return p + c; }); "); var response = (ExecScriptResponse)engine.PostWithReply(request); Assert.AreEqual((double)response.Data, 15D); } The problem is that there are so many points of failure in this test and similar tests that it almost doesn't seem worth it. It almost seems like my effort would be better spent reducing coupling between modules. To write a true unit test I would have to assume something like this: [TestMethod] public void CommentTest() { const string toParse = "/*First Line\r\nSecond Line*/"; var analyzer = new LexicalAnalyzer(toParse); { Assert.IsInstanceOfType(analyzer.Next(), typeof(MultiLineComment)); Assert.AreEqual(analyzer.Current.Value, "First Line\r\nSecond Line"); } } Doing this would require me to write thousands of tests which once again does not seem worth it.

  • Github file size limit changed 6/18/13. Can't push now

    - by slindsey3000
    How does this change as of June 18, 2013 affect my existing repository with a file that exceeds that limit? I last pushed 2 months ago with a large file. I have a large file that I have removed locally but I can not push anything now. I get a "remote error" ... remote: error: File cron_log.log is 126.91 MB; this exceeds GitHub's file size limit of 100 MB I added the file to .gitignore after original push... But it still exists on remote (origin) Removing it locally should get rid of it at origin(Github) right? ... but ... it is not letting me push because there is a file on Github that exceeds the limit... https://github.com/blog/1533-new-file-size-limits These are the commands I issued plus error messages.. git add . git commit -m "delete cron_log.log" git push origin master remote: Error code: 40bef1f6653fd2410fb2ab40242bc879 remote: warning: Error GH413: Large files detected. remote: warning: See http://git.io/iEPt8g for more information. remote: error: File cron_log.log is 141.41 MB; this exceeds GitHub's file size limit of 100 MB remote: error: File cron_log.log is 126.91 MB; this exceeds GitHub's file size limit of 100 MB To https://github.com/slinds(omited_here)/linexxxx(omited_here).git !

  • Recurrence relation solution

    - by Travis
    I'm revising past midterms for a final exam this week and am trying to make sense of a solution my professor posted for one of past exams. (You can see the original pdf here, question #6). I'm given the original recurrence relation T(m)=3T(n/2) + n and am told T(1) = 1. I'm pretty sure the solution I've been given is wrong in a few places. The solution is as follows: Let n=2^m T(2^m) = 3T(2^(m-1)) + 2^m 3T(2^(m-1)) = 3^2*T(2^(m-2)) + 2^(m-1)*3 ... 3^(m-1)T(2) = T(1) + 2*3^(m-1) I'm pretty sure this last line is incorrect and they forgot to multiply T(1) by 3^m. He then (tries to) sum the expressions: T(2^m) = 1 + (2^m + 2^(m-1)*3 + ... + 2*3(m-1)) = 1 + 2^m(1 + (3/2)^1 + (3/2)^2 + ... + (3/2)^(m-1)) = 1 + 2^m((3/2)^m-1)*(1/2) = 1 + 3^m - 2^(m-1) = 1 + n^log 3 - n/2 Thus the algorithm is big Theta of (n^log 3). I'm pretty sure that he also got the summation wrong here. By my calculations this should be as follows: T(2^m) = 2^m + 3 * 2^(m-1) + 3^2 * 2^(m-2) + ... + 3^m (3^m because 3^m*T(1) = 3^m should be added, not 1) = 2^m * ((3/2)^1 + (3/2)^2 + ... + (3/2)^m) = 2^m * sum of (3/2)^i from i=0 to m = 2^m * ((3/2)^(m+1) - 1)/(3/2 - 1) = 2^m * ((3/2)^(m+1) - 1)/(1/2) = 2^(m+1) * 3^(m+1)/2^(m+1) - 2^(m+1) = 3^(m+1) - 2 * 2^m Replacing n = 2^m, and from that m = log n T(n) = 3*3^(log n) - 2*n n is O(3^log n), thus the runtime is big Theta of (3^log n) Does this seem right? Thanks for your help!

  • Grails - Simple hasMany Problem - How does 'save' work?

    - by gav
    My problem is this: I want to create a grails domain instance, defining the 'Many' instances of another domain that it has. I have the actual source in a Google Code Project but the following should illustrate the problem. class Person { String name static hasMany[skills:Skill] static constraints = { id (visible:false) skills (nullable:false, blank:false) } } class Skill { String name String description static constraints = { id (visible:false) name (nullable:false, blank:false) description (nullable:false, blank:false) } } If you use this model and def scaffold for the two Controllers then you end up with a form like this that doesn't work; My own attempt to get this to work enumerates the Skills as checkboxes and looks like this; But when I save the Volunteer the skills are null! This is the code for my save method; def save = { log.info "Saving: " + params.toString() def skills = params.skills log.info "Skills: " + skills def volunteerInstance = new Volunteer(params) log.info volunteerInstance if (volunteerInstance.save(flush: true)) { flash.message = "${message(code: 'default.created.message', args: [message(code: 'volunteer.label', default: 'Volunteer'), volunteerInstance.id])}" redirect(action: "show", id: volunteerInstance.id) log.info volunteerInstance } else { render(view: "create", model: [volunteerInstance: volunteerInstance]) } } This is my log output (I have custom toString() methods); 2010-05-10 21:06:41,494 [http-8080-3] INFO bumbumtrain.VolunteerController - Saving: ["skills":["1", "2"], "name":"Ian", "_skills":["", ""], "create":"Create", "action":"save", "controller":"volunteer"] 2010-05-10 21:06:41,495 [http-8080-3] INFO bumbumtrain.VolunteerController - Skills: [1, 2] 2010-05-10 21:06:41,508 [http-8080-3] INFO bumbumtrain.VolunteerController - Volunteer[ id: null | Name: Ian | Skills [Skill[ id: 1 | Name: Carpenter ] , Skill[ id: 2 | Name: Sound Engineer ] ]] Note that in the final log line the right Skills have been picked up and are part of the object instance. When the volunteer is saved the 'Skills' are ignored and not commited to the database despite the in memory version created clearly does have the items. Is it not possible to pass the Skills at construction time? There must be a way round this? I need a single form to allow a person to register but I want to normalise the data so that I can add more skills at a later time. If you think this should 'just work' then a link to a working example would be great. Hope this makes sense, thanks in advance! Gav

  • How to make Nlog archive a file with the date when the logging took place.

    - by Carl Bergquist
    Hi, We are using Nlog as our logging framework and I cannot find a way to archive files the way I want. I would like to have the date of when the logging took place in the logging file name. Ex All logging that happend from 2009-10-01 00:00 -> 2009-10-01:23:59 should be placed in Log.2009-10-01.log The current NLog.config that I use looks like this. <?xml version="1.0" encoding="utf-8" ?> <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > <extensions> <add assembly="My.Awesome.LoggingExentions"/> </extensions> <targets> <target name="file1" xsi:type="File" fileName="${basedir}/Logs/Log.log" layout="${longdate} ${level:uppercase=true:padding=5} ${session} ${storeid} ${msisdn} - ${logger:shortName=true} - ${message} ${exception:format=tostring}" archiveEvery="Day" archiveFileName="${basedir}/Logs/Log${shortdate}-{#}.log" archiveNumbering="Sequence" maxArchiveFiles="99999" keepFileOpen="true" /> </targets> <rules> <logger name="*" minlevel="Trace" writeTo="file1" /> </rules> </nlog> This however sets the date in the logfile to the date when the new logfile is created. Which cause frustration when you want to read logs later. It also seems like I have to have atleast on # in the archiveFileName, which I rather not. So if you got a solution for that also I would be twice as thankful =)

  • Grails bean-fields plugin

    - by Don
    Hi, I'm having problems using the Grails bean-fields plugin with a class this is annotated Validateable, but is not a domain/command class. The root cause of the problem appears to be in this method of BeanTagLib.groovy private def getBeanConstraints(bean) { if (bean?.metaClass?.hasProperty(bean, 'constraints')) { def cons = bean.constraints if (cons != null) { if (log.debugEnabled) { log.debug "Bean is of type ${bean.class} - the constraints property was a [${cons.class}]" } // Safety check for the case where bean is no a proper domain/command object // This avoids confusing errors where constraints comes back as a Closure if (!(cons instanceof Map)) { if (log.warnEnabled) { log.warn "Bean of type ${bean.class} is not a domain class, command object or other validateable object - the constraints property was a [${cons.class}]" } } } else { if (log.warnEnabled) { log.warn "Bean of type ${bean.class} has no constraints" } } return cons } else return null } I tested out this method above in the grails console and when I pass an instance of MyBean into this method, it logs: Bean of type ${bean.class} is not a domain class, command object or other validateable object - the constraints property was a [${cons.class}] Because the constraints are returned as an instance of Closure instead of a Map. If I could figue out how to get a Map reference to the constraints of a @Validateable class (that is not a domain/command class), I guess I could resolve the problem. Thanks, Don

  • ERROR: failed to load JDBC driver - org.hsqldb.jdbcDriver

    - by maximus
    i wrote a connector class to connect to the hsqldb. here is my code: import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; import org.apache.log4j.Logger; public class hsqlmanager { private static final Logger log = Logger.getLogger(hsqlmanager.class); private static Connection con=null; private static void openConnection(){ try { Class.forName("org.hsqldb.jdbcDriver" ); log.info("Loaded JDBC Driver"); } catch (Exception e) { log.error("ERROR: failed to load JDBC driver - " + e.getMessage()); return; } try { con = DriverManager.getConnection("jdbc:hsqldb:hsql://localhost/sepm_db","sa",""); } catch(SQLException e){ log.error(e.getMessage()); } } public static void closeConnection() { try { con.close(); } catch(SQLException e) { log.error(e.getMessage()); } } public static Connection getConnection() { if (con==null){ openConnection(); } else { try { if(con.isClosed()){ con = DriverManager.getConnection("jdbc:hsqldb:hsql://localhost/sepm_db","sa",""); } } catch(SQLException e){ log.error(e.getMessage()); return null; } } return con; } } When I compile that I get ERROR: failed to load JDBC driver - org.hsqldb.jdbcDriver. Why?

  • SendMessage to window created by AllocateHWND cause deadlock

    - by user2704265
    In my Delphi project, I derive a thread class TMyThread, and follow the advice from forums to use AllocateHWnd to create a window handle. In TMyThread object, I call SendMessage to send message to the window handle. When the messages sent are in small volume, then the application works well. However, when the messages are in large volume, the application will deadlock and lose responses. I think may be the message queue is full as in LogWndProc, there are only codes to process the message, but no codes to remove the messages from the queue, that may cause all the processed messages still exist in the queue and the queue becomes full. Is that correct? The codes are attached below: var hLogWnd: HWND = 0; procedure TForm1.FormCreate(Sender: TObject); begin hLogWnd := AllocateHWnd(LogWndProc); end; procedure TForm1.FormDestroy(Sender: TObject); begin if hLogWnd <> 0 then DeallocateHWnd(hLogWnd); end; procedure TForm1.LogWndProc(var Message: TMessage); var S: PString; begin if Message.Msg = WM_UPDATEDATA then begin S := PString(msg.LParam); try List1.Items.Add(S^); finally Dispose(S); end; end else Message.Result := DefWindowProc(hLogWnd, Message.Msg, Message.WParam, Message.LParam); end; procedure TMyThread.SendLog(I: Integer); var Log: PString; begin New(Log); Log^ := 'Log: current stag is ' + IntToStr(I); SendMessage(hLogWnd, WM_UPDATEDATA, 0, LPARAM(Log)); Dispose(Log); end;

  • Best practices for Java logging from multiple threads?

    - by Jason S
    I want to have a diagnostic log that is produced by several tasks managing data. These tasks may be in multiple threads. Each task needs to write an element (possibly with subelements) to the log; get in and get out quickly. If this were a single-task situation I'd use XMLStreamWriter as it seems like the best match for simplicity/functionality without having to hold a ballooning XML document in memory. But it's not a single-task situation, and I'm not sure how to best make sure this is "threadsafe", where "threadsafe" in this application means that each log element should be written to the log correctly and serially (one after the other and not interleaved in any way). Any suggestions? I have a vague intuition that the way to go is to use a queue of log elements (with each one able to be produced quickly: my application is busy doing real work that's performance-sensitive), and have a separate thread which handles the log elements and sends them to a file so the logging doesn't interrupt the producers. The logging doesn't necessarily have to be XML, but I do want it to be structured and machine-readable. edit: I put "threadsafe" in quotes. Log4j seems to be the obvious choice (new to me but old to the community), why reinvent the wheel...

  • Multhreading in Java

    - by Vijay Selvaraj
    I'm working with core java and IBM Websphere MQ 6.0. We have a standalone module say DBcomponent that hits the database and fetches a resultset based on the runtime query. The query is passed to the application via MQ messaging medium. We have a trigger configured for the queue which invokes the DBComponent whenever a message is available in the queue. The DBComponent consumes the message, constructs the query and returns the resultset to another queue. In this overall process we use log4j to log statements on a log file for auditing. The connection is pooled to the database using Apache pool. I am trying to check whether the log messages are logged correctly using a sample program. The program places the input message to the queue and checks for the logs in the log file. Its expected for the trigger method invocation to complete before i try to check for the message in log file, but every time my program to check for log message gets executed first leading my check to failure. Even if i introduce a Thread.sleep(time) doesn't solves the case. How can i make it to keep my method execution waiting until the trigger operation completes? Any suggestion will be helpful.

  • Lucene and Special Characters

    - by Brandon
    I am using Lucene.Net 2.0 to index some fields from a database table. One of the fields is a 'Name' field which allows special characters. When I perform a search, it does not find my document that contains a term with special characters. I index my field as such: Directory DALDirectory = FSDirectory.GetDirectory(@"C:\Indexes\Name", false); Analyzer analyzer = new StandardAnalyzer(); IndexWriter indexWriter = new IndexWriter(DALDirectory, analyzer, true, IndexWriter.MaxFieldLength.UNLIMITED); Document doc = new Document(); doc.Add(new Field("Name", "Test (Test)", Field.Store.YES, Field.Index.TOKENIZED)); indexWriter.AddDocument(doc); indexWriter.Optimize(); indexWriter.Close(); And I search doing the following: value = value.Trim().ToLower(); value = QueryParser.Escape(value); Query searchQuery = new TermQuery(new Term(field, value)); Searcher searcher = new IndexSearcher(DALDirectory); TopDocCollector collector = new TopDocCollector(searcher.MaxDoc()); searcher.Search(searchQuery, collector); ScoreDoc[] hits = collector.TopDocs().scoreDocs; If I perform a search for field as 'Name' and value as 'Test', it finds the document. If I perform the same search as 'Name' and value as 'Test (Test)', then it does not find the document. Even more strange, if I remove the QueryParser.Escape line do a search for a GUID (which, of course, contains hyphens) it finds documents where the GUID value matches, but performing the same search with the value as 'Test (Test)' still yields no results. I am unsure what I am doing wrong. I am using the QueryParser.Escape method to escape the special characters and am storing the field and searching by the Lucene.Net's examples. Any thoughts?
