• Controlling clone access to multiple mercurial repos served via hgwebdir.cgi

  - by chrislawlor

  I'm trying to host multiple hg repositories to use for my clients. I need to control access to each repository individually - not just push access, but clone as well. I've got an .htaccess set which requires authentication globally: AuthUserFile /path/to/hgweb.passwd AuthGroupFile /dev/null AuthName "Chris Lawlor Client Mercurial Repositories" AuthType Basic <Limit GET POST PUT> Require valid-user </Limit> <FilesMatch "\.(htaccess|passwd|config|bak)$"> Order Allow,Deny Deny from all </FilesMatch> Then in each repository, I've got a .hg/hgrc file requiring a valid user [web] allow_push = <comma seperated user list> This almost does what I need. The problem is that I need to add ALL my clients to hgweb.passwd, which gives them clone access to ALL of the repositories. The only solution I can think of is to have another .htaccess and .passwd file in EACH repository. I don't really want to do that though, seems a little convoluted. I can already specify a list of authorized users for each repository in that repos' hgrc file with the allow_push setting. If only there were an allow_clone setting as well... All the documentation I've found for hgwebdir.cgi is incomplete. I've read: http://mercurial.selenic.com/wiki/HgWebDirStepByStep http://hgbook.red-bean.com/read/collaborating-with-other-people.html#sec:collab:cgi http://hgbook.red-bean.com/read/collaborating-with-other-people.html And others. I've yet to find a comprehensive list of hgrc settings. I guess this is as much an Apache question than a mercurial question. Unless I can find a better approach, I'll be going with a seperate .htaccess and .passwd file for each repo. This is a virtual host on Webfaction if it matters - set up roughly like this http://docs.webfaction.com/software/mercurial.html

• Gitosis problems

  - by user49884

  I've spent the last 14 days on git and gitosis problems. I did always find a way around my problems but now I'm stuck. To briefly summarize the situation: I have setup gitosis, created a project and I can check in and out of it. Then I added another uses, giving him access to the project by adding him to gitosis.conf, but he can not even clone project. Then I added yet another user for the same project (following same procedure), he has access to everything (clone, pull and push). Finally, I added one more user who can not do anything either. I could live with all of this, because I have access to work on the project. Now I have added a new project, or have I? To my best believe, I have done everything the exact same way as with the first project. I do not get a repository in the repository folder on my server (when doing "git remote add..." and push). I have tried following ALL the guides google gave me on "how to create a new repository gitosis" (is up to page 7 before not ALL hits are marked as visited). I have also tried to follow a different path, starting with "git init --bare" on the server, and then try to clone it. Didn't work either. I get the following error no matter what I try: ERROR: gitosis.serve.main: Repository read access denied fatal: The remote than hung up unexpectedly (But it works fine for accessing gitosis-admin and my first project) Then I read about debugging of gitosis. I have tried with -v, --verbose and adding LogLevel = DEBUG in gitosis.conf, none of these give me extra information. Project setup gitosis.conf: [group project] writable = project members = me LogLevel = DEBUG To my best believe, everything is done the exact same way, as I did when setting up my first project. I'm really stuck, how do I proceed now?

• Is there any equivalence of `--depth immediates` in `git`?

  - by ???

  Currently, I'm try to setup git front-end to the Subversion repository. My Subversion repository is a single large repository which consists of several co-related projects: svn-root |-- project1 | |-- branches | |-- tags | `-- trunk |-- project2 | |-- branches | |-- tags | `-- trunk `-- project3 |-- branches |-- tags `-- trunk Because it's sometimes needs to move files between different projects, so I don't want to break the repository to separate ones. I'm going to use git-svn to setup a git front-end, but I don't see how to exactly mapping the svn to git structure. The two systems treat branches and tags very different and I doubt it is possible. To simplify the problem, I would just git svn clone the whole root directory and let branches/tags/trunk directories just sit there. But this will definitely result in too many files in branches and tags directories. In Subversion, it's easy to just set the depth of checkout to immediates, which will only checkout the branch/tag titles, without the directory contents. but I don't know if this can be done in git. The git-svn messed me up. I hope there's more elegant solution.

• Overview of SOA Diagnostics in 11.1.1.6

  - by ShawnBailey

  What tools are available for diagnosing SOA Suite issues? There are a variety of tools available to help you and Support diagnose SOA Suite issues in 11g but it can be confusing as to which tool is appropriate for a particular situation and what their relationships are. This blog post will introduce the various tools and attempt to clarify what each is for and how they are related. Let's first list the tools we'll be addressing: RDA: Remote Diagnostic Agent DFW: Diagnostic Framework Selective Tracing DMS: Dynamic Monitoring Service ODL: Oracle Diagnostic Logging ADR: Automatic Diagnostics Repository ADRCI: Automatic Diagnostics Repository Command Interpreter WLDF: WebLogic Diagnostic Framework This overview is not mean to be a comprehensive guide on using all of these tools, however, extensive reference materials are included that will provide many more details on their execution. Another point to note is that all of these tools are applicable for Fusion Middleware as a whole but specific products may or may not have implemented features to leverage them. A couple of the tools have a WebLogic Scripting Tool or 'WLST' interface. WLST is a command interface for executing pre-built functions and custom scripts against a domain. A detailed WLST tutorial is beyond the scope of this post but you can find general information here. There are more specific resources in the below sections. In this post when we refer to 'Enterprise Manager' or 'EM' we are referring to Enterprise Manager Fusion Middleware Control. RDA (Remote Diagnostic Agent) RDA is a standalone tool that is used to collect both static configuration and dynamic runtime information from the SOA environment. RDA is generally run manually from the command line against a domain or single server. When opening a new Service Request, including an RDA collection can dramatically decrease the back and forth required to collect logs and configuration information for Support. After installing RDA you configure it to use the SOA Suite module as decribed in the referenced resources. The SOA module includes the Oracle WebLogic Server (WLS) module by default in order to include all of the relevant information for the environment. In addition to this basic configuration there is also an advanced mode where you can set the number of thread dumps for the collections, log files, Incidents, etc. When would you use it? When creating a Service Request or otherwise working with Oracle resources on an issue, capturing environment snapshots to baseline your configuration or to diagnose an issue on your own. How is it related to the other tools? RDA is related to DFW in that it collects the last 10 Incidents from the server by default. In a similar manner, RDA is related to ODL through its collection of the diagnostic logs and these may contain information from Selective Tracing sessions. Examples of what it currently collects: (for details please see the links in the Resources section) Diagnostic Logs (ODL) Diagnostic Framework Incidents (DFW) SOA MDS Deployment Descriptors SOA Repository Summary Statistics Thread Dumps Complete Domain Configuration RDA Resources: Webcast Recording: Using RDA with Oracle SOA Suite 11g Blog Post: Diagnose SOA Suite 11g Issues Using RDA Download RDA How to Collect Analysis Information Using RDA for Oracle SOA Suite 11g Products [ID 1350313.1] How to Collect Analysis Information Using RDA for Oracle SOA Suite and BPEL Process Manager 11g [ID 1352181.1] Getting Started With Remote Diagnostic Agent: Case Study - Oracle WebLogic Server (Video) [ID 1262157.1] top DFW (Diagnostic Framework) DFW provides the ability to collect specific information for a particular problem when that problem occurs. DFW is included with your SOA Suite installation and deployed to the domain. Let's define the components of DFW. Diagnostic Dumps: Specific diagnostic collections that are defined at either the 'system' or product level. Examples would be diagnostic logs or thread dumps. Incident: A collection of Diagnostic Dumps associated with a particular problem Log Conditions: An Oracle Diagnostic Logging event that DFW is configured to listen for. If the event is identified then an Incident will be created. WLDF Watch: The WebLogic Diagnostic Framework or 'WLDF' is not a component of DFW, however, it can be a source of DFW Incident creation through the use of a 'Watch'. WLDF Notification: A Notification is a component of WLDF and is the link between the Watch and DFW. You can configure multiple Notification types in WLDF and associate them with your Watches. 'FMWDFW-notification' is available to you out of the box to allow for DFW notification of Watch execution. Rule: Defines a WLDF Watch or Log Condition for which we want to associate a set of Diagnostic Dumps. When triggered the specified dumps will be collected and added to the Incident Rule Action: Defines the specific Diagnostic Dumps to collect for a particular rule ADR: Automatic Diagnostics Repository; Defined for every server in a domain. This is where Incidents are stored Now let's walk through a simple flow: Oracle Web Services error message OWS-04086 (SOAP Fault) is generated on managed server 1 DFW Log Condition for OWS-04086 evaluates to TRUE DFW creates a new Incident in the ADR for managed server 1 DFW executes the specified Diagnostic Dumps and adds the output to the Incident In this case we'll grab the diagnostic log and thread dump. We might also want to collect the WSDL binding information and SOA audit trail When would you use it? When you want to automatically collect Diagnostic Dumps at a particular time using a trigger or when you want to manually collect the information. In either case it can be readily uploaded to Oracle Support through the Service Request. How is it related to the other tools? DFW generates Incidents which are collections of Diagnostic Dumps. One of the system level Diagonstic Dumps collects the current server diagnostic log which is generated by ODL and can contain information from Selective Tracing sessions. Incidents are included in RDA collections by default and ADRCI is a tool that is used to package an Incident for upload to Oracle Support. In addition, both ODL and DMS can be used to trigger Incident creation through DFW. The conditions and rules for generating Incidents can become quite complicated and the below resources go into more detail. A simpler approach to leveraging at least the Diagnostic Dumps is through WLST (WebLogic Scripting Tool) where there are commands to do the following: Create an Incident Execute a single Diagnostic Dump Describe a Diagnostic Dump List the available Diagnostic Dumps The WLST option offers greater control in what is generated and when. It can be a great help when collecting information for Support. There are overlaps with RDA, however, DFW is geared towards collecting specific runtime information when an issue occurs while existing Incidents are collected by RDA. There are 3 WLDF Watches configured by default in a SOA Suite 11g domain: Stuck Threads, Unchecked Exception and Deadlock. These Watches are enabled by default and will generate Incidents in ADR. They are configured to reset automatically after 30 seconds so they have the potential to create multiple Incidents if these conditions are consistent. The Incidents generated by these Watches will only contain System level Diagnostic Dumps. These same System level Diagnostic Dumps will be included in any application scoped Incident as well. Starting in 11.1.1.6, SOA Suite is including its own set of application scoped Diagnostic Dumps that can be executed from WLST or through a WLDF Watch or Log Condition. These Diagnostic Dumps can be added to an Incident such as in the earlier example using the error code OWS-04086. soa.config: MDS configuration files and deployed-composites.xml soa.composite: All artifacts related to the deployed composite soa.wsdl: Summary of endpoints configured for the composite soa.edn: EDN configuration summary if applicable soa.db: Summary DB information for the SOA repository soa.env: Coherence cluster configuration summary soa.composite.trail: Partial audit trail information for the running composite The current release of RDA has the option to collect the soa.wsdl and soa.composite Diagnostic Dumps. More Diagnostic Dumps for SOA Suite products are planned for future releases along with enhancements to DFW itself. DFW Resources: Webcast Recording: SOA Diagnostics Sessions: Diagnostic Framework Diagnostic Framework Documentation DFW WLST Command Reference Documentation for SOA Diagnostic Dumps in 11.1.1.6 top Selective Tracing Selective Tracing is a facility available starting in version 11.1.1.4 that allows you to increase the logging level for specific loggers and for a specific context. What this means is that you have greater capability to collect needed diagnostic log information in a production environment with reduced overhead. For example, a Selective Tracing session can be executed that only increases the log level for one composite, only one logger, limited to one server in the cluster and for a preset period of time. In an environment where dozens of composites are deployed this can dramatically reduce the volume and overhead of the logging without sacrificing relevance. Selective Tracing can be administered either from Enterprise Manager or through WLST. WLST provides a bit more flexibility in terms of exactly where the tracing is run. When would you use it? When there is an issue in production or another environment that lends itself to filtering by an available context criteria and increasing the log level globally results in too much overhead or irrelevant information. The information is written to the server diagnostic log and is exportable from Enterprise Manager How is it related to the other tools? Selective Tracing output is written to the server diagnostic log. This log can be collected by a system level Diagnostic Dump using DFW or through a default RDA collection. Selective Tracing also heavily leverages ODL fields to determine what to trace and to tag information that is part of a particular tracing session. Available Context Criteria: Application Name Client Address Client Host Composite Name User Name Web Service Name Web Service Port Selective Tracing Resources: Webcast Recording: SOA Diagnostics Session: Using Selective Tracing to Diagnose SOA Suite Issues How to Use Selective Tracing for SOA [ID 1367174.1] Selective Tracing WLST Reference top DMS (Dynamic Monitoring Service) DMS exposes runtime information for monitoring. This information can be monitored in two ways: Through the DMS servlet As exposed MBeans The servlet is deployed by default and can be accessed through http://<host>:<port>/dms/Spy (use administrative credentials to access). The landing page of the servlet shows identical columns of what are known as Noun Types. If you select a Noun Type you will see a table in the right frame that shows the attributes (Sensors) for the Noun Type and the available instances. SOA Suite has several exposed Noun Types that are available for viewing through the Spy servlet. Screenshots of the Spy servlet are available in the Knowledge Base article How to Monitor Runtime SOA Performance With the Dynamic Monitoring Service (DMS). Every Noun instance in the runtime is exposed as an MBean instance. As such they are generally available through an MBean browser and available for monitoring through WLDF. You can configure a WLDF Watch to monitor a particular attribute and fire a notification when the threshold is exceeded. A WLDF Watch can use the out of the box DFW notification type to notify DFW to create an Incident. When would you use it? When you want to monitor a metric or set of metrics either manually or through an automated system. When you want to trigger a WLDF Watch based on a metric exposed through DMS. How is it related to the other tools? DMS metrics can be monitored with WLDF Watches which can in turn notify DFW to create an Incident. DMS Resources: How to Monitor Runtime SOA Performance With the Dynamic Monitoring Service (DMS) [ID 1368291.1] How to Reset a SOA 11g DMS Metric DMS Documentation top ODL (Oracle Diagnostic Logging) ODL is the primary facility for most Fusion Middleware applications to log what they are doing. Whenever you change a logging level through Enterprise Manager it is ultimately exposed through ODL and written to the server diagnostic log. A notable exception to this is WebLogic Server which uses its own log format / file. ODL logs entries in a consistent, structured way using predefined fields and name/value pairs. Here's an example of a SOA Suite entry: [2012-04-25T12:49:28.083-06:00] [AdminServer] [ERROR] [] [oracle.soa.bpel.engine] [tid: [ACTIVE].ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'] [userId: ] [ecid: 0963fdde7e77631c:-31a6431d:136eaa46cda:-8000-00000000000000b4,0] [errid: 41] [WEBSERVICE_PORT.name: BPELProcess2_pt] [APP: soa-infra] [composite_name: TestProject2] [J2EE_MODULE.name: fabric] [WEBSERVICE.name: bpelprocess1_client_ep] [J2EE_APP.name: soa-infra] Error occured while handling a post operation[[ When would you use it? You'll use ODL almost every time you want to identify and diagnose a problem in the environment. The entries are written to the server diagnostic log. How is it related to the other tools? The server diagnostic logs are collected by DFW and RDA. Selective Tracing writes its information to the diagnostic log as well. Additionally, DFW log conditions are triggered by ODL log events. ODL Resources: ODL Documentation top ADR (Automatic Diagnostics Repository) ADR is not a tool in and of itself but is where DFW stores the Incidents it creates. Every server in the domain has an ADR location which can be found under <SERVER_HOME>/adr. This is referred to the as the ADR 'Base' location. ADR also has what are known as 'Home' locations. Example: You have a domain called 'myDomain' and an associated managed server called 'myServer'. Your admin server is called 'AdminServer'. Your domain home directory is called 'myDomain' and it contains a 'servers' directory. The 'servers' directory contains a directory for the managed server called 'myServer' and here is where you'll find the 'adr' directory which is the ADR 'Base' location for myServer. To get to the ADR 'Home' locations we drill through a few levels: diag/ofm/myDomain/ In an 11.1.1.6 SOA Suite domain you will see 2 directories here, 'myServer' and 'soa-infra'. These are the ADR 'Home' locations. 'myServer' is the 'system' ADR home and contains system level Incidents. 'soa-infra' is the name that SOA Suite used to register with DFW and this ADR home contains SOA Suite related Incidents Each ADR home location contains a series of directories, one of which is called 'incident'. This is where your Incidents are stored. When would you use it? It's a good idea to check on these locations from time to time to see whether a lot of Incidents are being generated. They can be cleaned out by deleting the Incident directories or through the ADRCI tool. If you know that an Incident is of particular interest for an issue you're working with Oracle you can simply zip it up and provide it. How does it relate to the other tools? ADR is obviously very important for DFW since it's where the Incidents are stored. Incidents contain Diagnostic Dumps that may relate to diagnostic logs (ODL) and DMS metrics. The most recent 10 Incident directories are collected by RDA by default and ADRCI relies on the ADR locations to help manage the contents. top ADRCI (Automatic Diagnostics Repository Command Interpreter) ADRCI is a command line tool for packaging and managing Incidents. When would you use it? When purging Incidents from an ADR Home location or when you want to package an Incident along with an offline RDA collection for upload to Oracle Support. How does it relate to the other tools? ADRCI contains a tool called the Incident Packaging System or IPS. This is used to package an Incident for upload to Oracle Support through a Service Request. Starting in 11.1.1.6 IPS will attempt to collect an offline RDA collection and include it with the Incident package. This will only work if Perl is available on the path, otherwise it will give a warning and package only the Incident files. ADRCI Resources: How to Use the Incident Packaging System (IPS) in SOA 11g [ID 1381259.1] ADRCI Documentation top WLDF (WebLogic Diagnostic Framework) WLDF is functionality available in WebLogic Server since version 9. Starting with FMw 11g a link has been added between WLDF and the pre-existing DFW, the WLDF Watch Notification. Let's take a closer look at the flow: There is a need to monitor the performance of your SOA Suite message processing A WLDF Watch is created in the WLS console that will trigger if the average message processing time exceeds 2 seconds. This metric is monitored through a DMS MBean instance. The out of the box DFW Notification (the Notification is called FMWDFW-notification) is added to the Watch. Under the covers this notification is of type JMX. The Watch is triggered when the threshold is exceeded and fires the Notification. DFW has a listener that picks up the Notification and evaluates it according to its rules, etc When it comes to automatic Incident creation, WLDF is a key component with capabilities that will grow over time. When would you use it? When you want to monitor the WLS server log or an MBean metric for some condition and fire a notification when the Watch is triggered. How does it relate to the other tools? WLDF is used to automatically trigger Incident creation through DFW using the DFW Notification.

• ODI SDK: Retrieving Information From the Logs

  - by Christophe Dupupet

  It is fairly common to want to retrieve data from the ODI logs: statistics, execution status, even the generated code can be retrieved from the logs. The ODI SDK provides a robust set of APIs to parse the repository and retreve such information. To locate the information you are looking for, you have to keep in mind the structure of the logs: sessions contain steps; steps containt tasks. The session is the execution unit: basically, each time you execute something (interface, package, procedure, scenario) you create a new session. The steps are the individual entries found in a session: these will be the icons in your package for instance. Or if you are running an interface, you will have one single step: the interface itself. The tasks will represent the more atomic elements of the steps: the individual DDL, DML, scripts and so forth that are generated by ODI, along with all the detailed statistics for that task. All these details can be retrieved with the SDK.

• How to build Open JavaFX for Android.

  - by PictureCo

  Here's a short recipe for baking JavaFX for Android dalvik. We will need just a few ingredients but each one requires special care. So let's get down to the business.  SourcesThe first ingredient is an open JavaFX repository. This should be piece of cake. As always there's a catch. You probably know that dalvik is jdk6 compatible  and also that certain APIs are missing comparing to good old java vm from Oracle.  Fortunately there is a repository which is a backport of regular OpenJFX to jdk7 and going from jdk7 to jdk6 is possible. The first thing to do is to clone or download the repository from https://bitbucket.org/narya/jfx78. Main page of the project says "It works in some cases" so we will presume that it will work in most cases As I've said dalvik vm misses some APIs which would lead to a build failures. To get them use another compatibility repository which is available on GitHub https://github.com/robovm/robovm-jfx78-compat. Download the zip and unzip sources into jfx78/modules/base.We need also a javafx binary stubs. Use jfxrt.jar from jdk8.The last thing to download are freetype sources from http://freetype.org. These will be necessary for native font rendering. Toolchain setup I have to point out that these instructions were tested only on linux. I suppose they will work with minimal changes also on Mac OS. I also presume that you were able to build open JavaFX. That means all tools like ant, gradle, gcc and jdk8 have been installed and are working all right. In addition to this you will need to download and install jdk7, Android SDK and Android NDK for native code compilation.  Installing all of them will take some time. Don't forget to put them in your path. export ANDROID_SDK=/opt/android-sdk-linux export ANDROID_NDK=/opt/android-ndk-r9b export JAVA_HOME=/opt/jdk1.7.0 export PATH=$JAVA_HOME/bin:$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools:$ANDROID_NDK FreetypeUnzip freetype release sources first. We will have to cross compile them for arm. Firstly we will create a standalone toolchain for cross compiling installed in ~/work/ndk-standalone-19. $ANDROID_NDK/build/tools/make-standalone-toolchain.sh  --platform=android-19 --install-dir=~/work/ndk-standalone-19 After the standalone toolchain has been created cross compile freetype with following script: export TOOLCHAIN=~/work/freetype/ndk-standalone-19 export PATH=$TOOLCHAIN/bin:$PATH export FREETYPE=`pwd` ./configure --host=arm-linux-androideabi --prefix=$FREETYPE/install --without-png --without-zlib --enable-shared sed -i 's/\-version\-info \$(version_info)/-avoid-version/' builds/unix/unix-cc.mk make make install It will compile and install freetype library into $FREETYPE/install. We will link to this install dir later on. It would be possible also to link openjfx font support dynamically against skia library available on Android which already contains freetype. It creates smaller result but can have compatibility problems. Patching Download patches javafx-android-compat.patch + android-tools.patch and patch jfx78 repository. I recommend to have look at patches. First one android-compat.patch updates openjfx build script, removes dependency on SharedSecret classes and updates LensLogger to remove dependency on jdk specific PlatformLogger. Second one android-tools.patch creates helper script in android-tools. The script helps to setup javaFX Android projects. Building Now is time to try the build. Run following script: JAVA_HOME=/opt/jdk1.7.0 JDK_HOME=/opt/jdk1.7.0 ANDROID_SDK=/opt/android-sdk-linux ANDROID_NDK=/opt/android-ndk-r9b PATH=$JAVA_HOME/bin:$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools:$ANDROID_NDK:$PATH gradle -PDEBUG -PDALVIK_VM=true -PBINARY_STUB=~/work/binary_stub/linux/rt/lib/ext/jfxrt.jar \ -PFREETYPE_DIR=~/work/freetype/install -PCOMPILE_TARGETS=android If everything went all right the output is in build/android-sdk Create first JavaFX Android project Use gradle script int android-tools. The script sets the project structure for you.   Following command creates Android HelloWorld project which links to a freshly built javafx runtime and to a HelloWorld application. NAME is a name of Android project. DIR where to create our first project. PACKAGE is package name required by Android. It has nothing to do with a packaging of javafx application. JFX_SDK points to our recently built runtime. JFX_APP points to dist directory of javafx application. (where all application jars sit) JFX_MAIN is fully qualified name of a main class. gradle -PDEBUG -PDIR=/home/user/work -PNAME=HelloWorld -PPACKAGE=com.helloworld \ -PJFX_SDK=/home/user/work/jfx78/build/android-sdk -PJFX_APP=/home/user/NetBeansProjects/HelloWorld/dist \ -PJFX_MAIN=com.helloworld.HelloWorld createProject Now cd to the created project and use it like any other android project. ant clean, debug, uninstall, installd will work. I haven't tried it from any IDE Eclipse nor Netbeans. Special thanks to Stefan Fuchs and Daniel Zwolenski for the repositories used in this blog post.

• ASP.NET Web API - Screencast series Part 3: Delete and Update

  - by Jon Galloway

  We're continuing a six part series on ASP.NET Web API that accompanies the getting started screencast series. This is an introductory screencast series that walks through from File / New Project to some more advanced scenarios like Custom Validation and Authorization. The screencast videos are all short (3-5 minutes) and the sample code for the series is both available for download and browsable online. I did the screencasts, but the samples were written by the ASP.NET Web API team. In Part 1 we looked at what ASP.NET Web API is, why you'd care, did the File / New Project thing, and did some basic HTTP testing using browser F12 developer tools. In Part 2 we started to build up a sample that returns data from a repository in JSON format via GET methods. In Part 3, we'll start to modify data on the server using DELETE and POST methods. So far we've been looking at GET requests, and the difference between standard browsing in a web browser and navigating an HTTP API isn't quite as clear. Delete is where the difference becomes more obvious. With a "traditional" web page, to delete something'd probably have a form that POSTs a request back to a controller that needs to know that it's really supposed to be deleting something even though POST was really designed to create things, so it does the work and then returns some HTML back to the client that says whether or not the delete succeeded. There's a good amount of plumbing involved in communicating between client and server. That gets a lot easier when we just work with the standard HTTP DELETE verb. Here's how the server side code works: public Comment DeleteComment(int id) { Comment comment; if (!repository.TryGet(id, out comment)) throw new HttpResponseException(HttpStatusCode.NotFound); repository.Delete(id); return comment; } If you look back at the GET /api/comments code in Part 2, you'll see that they start the exact same because the use cases are kind of similar - we're looking up an item by id and either displaying it or deleting it. So the only difference is that this method deletes the comment once it finds it. We don't need to do anything special to handle cases where the id isn't found, as the same HTTP 404 handling works fine here, too. Pretty much all "traditional" browsing uses just two HTTP verbs: GET and POST, so you might not be all that used to DELETE requests and think they're hard. Not so! Here's the jQuery method that calls the /api/comments with the DELETE verb: $(function() { $("a.delete").live('click', function () { var id = $(this).data('comment-id'); $.ajax({ url: "/api/comments/" + id, type: 'DELETE', cache: false, statusCode: { 200: function(data) { viewModel.comments.remove( function(comment) { return comment.ID == data.ID; } ); } } }); return false; }); }); So in order to use the DELETE verb instead of GET, we're just using $.ajax() and setting the type to DELETE. Not hard. But what's that statusCode business? Well, an HTTP status code of 200 is an OK response. Unless our Web API method sets another status (such as by throwing the Not Found exception we saw earlier), the default response status code is HTTP 200 - OK. That makes the jQuery code pretty simple - it calls the Delete action, and if it gets back an HTTP 200, the server-side delete was successful so the comment can be deleted. Adding a new comment uses the POST verb. It starts out looking like an MVC controller action, using model binding to get the new comment from JSON data into a c# model object to add to repository, but there are some interesting differences. public HttpResponseMessage<Comment> PostComment(Comment comment) { comment = repository.Add(comment); var response = new HttpResponseMessage<Comment>(comment, HttpStatusCode.Created); response.Headers.Location = new Uri(Request.RequestUri, "/api/comments/" + comment.ID.ToString()); return response; } First off, the POST method is returning an HttpResponseMessage<Comment>. In the GET methods earlier, we were just returning a JSON payload with an HTTP 200 OK, so we could just return the  model object and Web API would wrap it up in an HttpResponseMessage with that HTTP 200 for us (much as ASP.NET MVC controller actions can return strings, and they'll be automatically wrapped in a ContentResult). When we're creating a new comment, though, we want to follow standard REST practices and return the URL that points to the newly created comment in the Location header, and we can do that by explicitly creating that HttpResposeMessage and then setting the header information. And here's a key point - by using HTTP standard status codes and headers, our response payload doesn't need to explain any context - the client can see from the status code that the POST succeeded, the location header tells it where to get it, and all it needs in the JSON payload is the actual content. Note: This is a simplified sample. Among other things, you'll need to consider security and authorization in your Web API's, and especially in methods that allow creating or deleting data. We'll look at authorization in Part 6. As for security, you'll want to consider things like mass assignment if binding directly to model objects, etc. In Part 4, we'll extend on our simple querying methods form Part 2, adding in support for paging and querying.

• jQuery Selector Tester and Cheat Sheet

  - by SGWellens

  I've always appreciated these tools: Expresso and XPath Builder. They make designing regular expressions and XPath selectors almost fun! Did I say fun? I meant less painful. Being able to paste/load text and then interactively play with the search criteria is infinitely better than the code/compile/run/test cycle. It's faster and you get a much better feel for how the expressions work. So, I decided to make my own interactive tool to test jQuery selectors:  jQuery Selector Tester.   Here's a sneak peek: Note: There are some existing tools you may like better: http://www.woods.iki.fi/interactive-jquery-tester.html http://www.w3schools.com/jquery/trysel.asp?filename=trysel_basic&jqsel=p.intro,%23choose My tool is different: It is one page. You can save it and run it locally without a Web Server. It shows the results as a list of iterated objects instead of highlighted html. A cheat sheet is on the same page as the tester which is handy. I couldn't upload an .htm or .html file to this site so I hosted it on my personal site here: jQuery Selector Tester. Design Highlights: To make the interactive search work, I added a hidden div to the page: <!--Hidden div holds DOM elements for jQuery to search--><div id="HiddenDiv" style="display: none"></div> When ready to search, the searchable html text is copied into the hidden div…this renders the DOM tree in the hidden div: // get the html to search, insert it to the hidden divvar Html = $("#TextAreaHTML").val();$("#HiddenDiv").html(Html); When doing a search, I modify the search pattern to look only in the HiddenDiv. To do that, I put a space between the patterns.  The space is the Ancestor operator (see the Cheat Sheet): // modify search string to only search in our// hidden div and do the searchvar SearchString = "#HiddenDiv " + SearchPattern;try{    var $FoundItems = $(SearchString);}   Big Fat Stinking Faux Pas: I was about to publish this article when I made a big mistake: I tested the tool with Mozilla FireFox. It blowed up…it blowed up real good. In the past I’ve only had to target IE so this was quite a revelation. When I started to learn JavaScript, I was disgusted to see all the browser dependent code. Who wants to spend their time testing against different browsers and versions of browsers? Adding a bunch of ‘if-else’ code is a tedious and thankless task. I avoided client code as much as I could. Then jQuery came along and all was good. It was browser independent and freed us from the tedium of worrying about version N of the Acme browser. Right? Wrong! I had used outerHTML to display the selected elements. The problem is Mozilla FireFox doesn’t implement outerHTML. I replaced this: // encode the html markupvar OuterHtml = $('<div/>').text(this.outerHTML).html(); With this: // encode the html markupvar Html = $('<div>').append(this).html();var OuterHtml = $('<div/>').text(Html).html(); Another problem was that Mozilla FireFox doesn’t implement srcElement. I replaced this: var Row = e.srcElement.parentNode;  With this: var Row = e.target.parentNode; Another problem was the indexing. The browsers have different ways of indexing. I replaced this: // this cell has the search pattern  var Cell = Row.childNodes[1];   // put the pattern in the search box and search                    $("#TextSearchPattern").val(Cell.innerText);  With this: // get the correct cell and the text in the cell// place the text in the seach box and serachvar Cell = $(Row).find("TD:nth-child(2)");var CellText = Cell.text();$("#TextSearchPattern").val(CellText);   So much for the myth of browser independence. Was I overly optimistic and gullible? I don’t think so. And when I get my millions from the deposed Nigerian prince I sent money to, you’ll see that having faith is not futile. Notes: My goal was to have a single standalone file. I tried to keep the features and CSS to a minimum–adding only enough to make it useful and visually pleasing. When testing, I often thought there was a problem with the jQuery selector. Invariable it was invalid html code. If your results aren't what you expect, don't assume it's the jQuery selector pattern: The html may be invalid. To help in development and testing, I added a double-click handler to the rows in the Cheat Sheet table. If you double-click a row, the search pattern is put in the search box, a search is performed and the page is scrolled so you can see the results. I left the test html and code in the page. If you are using a CDN (non-local) version of the jQuery libraray, the designer in Visual Studio becomes extremely slow.  That's why there are two version of the library in the header and one is commented out. For reference, here is the jQuery documentation on selectors: http://api.jquery.com/category/selectors/ Here is a much more comprehensive list of CSS selectors (which jQuery uses): http://www.w3.org/TR/CSS2/selector.html I hope someone finds this useful.

• SQL SERVER – SSIS Parameters in Parent-Child ETL Architectures – Notes from the Field #040

  - by Pinal Dave

  [Notes from Pinal]: SSIS is very well explored subject, however, there are so many interesting elements when we read, we learn something new. A similar concept has been Parent-Child ETL architecture’s relationship in SSIS. Linchpin People are database coaches and wellness experts for a data driven world. In this 40th episode of the Notes from the Fields series database expert Tim Mitchell (partner at Linchpin People) shares very interesting conversation related to how to understand SSIS Parameters in Parent-Child ETL Architectures. In this brief Notes from the Field post, I will review the use of SSIS parameters in parent-child ETL architectures. A very common design pattern used in SQL Server Integration Services is one I call the parent-child pattern.  Simply put, this is a pattern in which packages are executed by other packages.  An ETL infrastructure built using small, single-purpose packages is very often easier to develop, debug, and troubleshoot than large, monolithic packages.  For a more in-depth look at parent-child architectures, check out my earlier blog post on this topic. When using the parent-child design pattern, you will frequently need to pass values from the calling (parent) package to the called (child) package.  In older versions of SSIS, this process was possible but not necessarily simple.  When using SSIS 2005 or 2008, or even when using SSIS 2012 or 2014 in package deployment mode, you would have to create package configurations to pass values from parent to child packages.  Package configurations, while effective, were not the easiest tool to work with.  Fortunately, starting with SSIS in SQL Server 2012, you can now use package parameters for this purpose. In the example I will use for this demonstration, I’ll create two packages: one intended for use as a child package, and the other configured to execute said child package.  In the parent package I’m going to build a for each loop container in SSIS, and use package parameters to pass in a value – specifically, a ClientID – for each iteration of the loop.  The child package will be executed from within the for each loop, and will create one output file for each client, with the source query and filename dependent on the ClientID received from the parent package. Configuring the Child and Parent Packages When you create a new package, you’ll see the Parameters tab at the package level.  Clicking over to that tab allows you to add, edit, or delete package parameters. As shown above, the sample package has two parameters.  Note that I’ve set the name, data type, and default value for each of these.  Also note the column entitled Required: this allows me to specify whether the parameter value is optional (the default behavior) or required for package execution.  In this example, I have one parameter that is required, and the other is not. Let’s shift over to the parent package briefly, and demonstrate how to supply values to these parameters in the child package.  Using the execute package task, you can easily map variable values in the parent package to parameters in the child package. The execute package task in the parent package, shown above, has the variable vThisClient from the parent package mapped to the pClientID parameter shown earlier in the child package.  Note that there is no value mapped to the child package parameter named pOutputFolder.  Since this parameter has the Required property set to False, we don’t have to specify a value for it, which will cause that parameter to use the default value we supplied when designing the child pacakge. The last step in the parent package is to create the for each loop container I mentioned earlier, and place the execute package task inside it.  I’m using an object variable to store the distinct client ID values, and I use that as the iterator for the loop (I describe how to do this more in depth here).  For each iteration of the loop, a different client ID value will be passed into the child package parameter. The final step is to configure the child package to actually do something meaningful with the parameter values passed into it.  In this case, I’ve modified the OleDB source query to use the pClientID value in the WHERE clause of the query to restrict results for each iteration to a single client’s data.  Additionally, I’ll use both the pClientID and pOutputFolder parameters to dynamically build the output filename. As shown, the pClientID is used in the WHERE clause, so we only get the current client’s invoices for each iteration of the loop. For the flat file connection, I’m setting the Connection String property using an expression that engages both of the parameters for this package, as shown above. Parting Thoughts There are many uses for package parameters beyond a simple parent-child design pattern.  For example, you can create standalone packages (those not intended to be used as a child package) and still use parameters.  Parameter values may be supplied to a package directly at runtime by a SQL Server Agent job, through the command line (via dtexec.exe), or through T-SQL. Also, you can also have project parameters as well as package parameters.  Project parameters work in much the same way as package parameters, but the parameters apply to all packages in a project, not just a single package. Conclusion Of the numerous advantages of using catalog deployment model in SSIS 2012 and beyond, package parameters are near the top of the list.  Parameters allow you to easily share values from parent to child packages, enabling more dynamic behavior and better code encapsulation. If you want me to take a look at your server and its settings, or if your server is facing any issue we can Fix Your SQL Server.

• JAVA image transfer problem

• Making your WCF Web Apis to speak in multiple languages

  - by cibrax

  One of the key aspects of how the web works today is content negotiation. The idea of content negotiation is based on the fact that a single resource can have multiple representations, so user agents (or clients) and servers can work together to chose one of them. The http specification defines several “Accept” headers that a client can use to negotiate content with a server, and among all those, there is one for restricting the set of natural languages that are preferred as a response to a request, “Accept-Language”. For example, a client can specify “es” in this header for specifying that he prefers to receive the content in spanish or “en” in english. However, there are certain scenarios where the “Accept-Language” header is just not enough, and you might want to have a way to pass the “accepted” language as part of the resource url as an extension. For example, http://localhost/ProductCatalog/Products/1.es” returns all the descriptions for the product with id “1” in spanish. This is useful for scenarios in which you want to embed the link somewhere, such a document, an email or a page.  Supporting both scenarios, the header and the url extension, is really simple in the new WCF programming model. You only need to provide a processor implementation for any of them. Let’s say I have a resource implementation as part of a product catalog I want to expose with the WCF web apis. [ServiceContract][Export]public class ProductResource{ IProductRepository repository;  [ImportingConstructor] public ProductResource(IProductRepository repository) { this.repository = repository; }  [WebGet(UriTemplate = "{id}")] public Product Get(string id, HttpResponseMessage response) { var product = repository.GetById(int.Parse(id)); if (product == null) { response.StatusCode = HttpStatusCode.NotFound; response.Content = new StringContent(Messages.OrderNotFound); }  return product; }} The Get method implementation in this resource assumes the desired culture will be attached to the current thread (Thread.CurrentThread.Culture). Another option is to pass the desired culture as an additional argument in the method, so my processor implementation will handle both options. This method is also using an auto-generated class for handling string resources, Messages, which is available in the different cultures that the service implementation supports. For example, Messages.resx contains “OrderNotFound”: “Order Not Found” Messages.es.resx contains “OrderNotFound”: “No se encontro orden” The processor implementation bellow tackles the first scenario, in which the desired language is passed as part of the “Accept-Language” header. public class CultureProcessor : Processor<HttpRequestMessage, CultureInfo>{ string defaultLanguage = null;  public CultureProcessor(string defaultLanguage = "en") { this.defaultLanguage = defaultLanguage; this.InArguments[0].Name = HttpPipelineFormatter.ArgumentHttpRequestMessage; this.OutArguments[0].Name = "culture"; }  public override ProcessorResult<CultureInfo> OnExecute(HttpRequestMessage request) { CultureInfo culture = null; if (request.Headers.AcceptLanguage.Count > 0) { var language = request.Headers.AcceptLanguage.First().Value; culture = new CultureInfo(language); } else { culture = new CultureInfo(defaultLanguage); }  Thread.CurrentThread.CurrentCulture = culture; Messages.Culture = culture;  return new ProcessorResult<CultureInfo> { Output = culture }; }}   As you can see, the processor initializes a new CultureInfo instance with the value provided in the “Accept-Language” header, and set that instance to the current thread and the auto-generated resource class with all the messages. In addition, the CultureInfo instance is returned as an output argument called “culture”, making possible to receive that argument in any method implementation   The following code shows the implementation of the processor for handling languages as url extensions.   public class CultureExtensionProcessor : Processor<HttpRequestMessage, Uri>{ public CultureExtensionProcessor() { this.OutArguments[0].Name = HttpPipelineFormatter.ArgumentUri; }  public override ProcessorResult<Uri> OnExecute(HttpRequestMessage httpRequestMessage) { var requestUri = httpRequestMessage.RequestUri.OriginalString;  var extensionPosition = requestUri.LastIndexOf(".");  if (extensionPosition > -1) { var extension = requestUri.Substring(extensionPosition + 1);  var query = httpRequestMessage.RequestUri.Query;  requestUri = string.Format("{0}?{1}", requestUri.Substring(0, extensionPosition), query); ;  var uri = new Uri(requestUri);  httpRequestMessage.Headers.AcceptLanguage.Clear();  httpRequestMessage.Headers.AcceptLanguage.Add(new StringWithQualityHeaderValue(extension));  var result = new ProcessorResult<Uri>();  result.Output = uri;  return result; }  return new ProcessorResult<Uri>(); }} The last step is to inject both processors as part of the service configuration as it is shown bellow, public void RegisterRequestProcessorsForOperation(HttpOperationDescription operation, IList<Processor> processors, MediaTypeProcessorMode mode){ processors.Insert(0, new CultureExtensionProcessor()); processors.Add(new CultureProcessor());} Once you configured the two processors in the pipeline, your service will start speaking different languages :). Note: Url extensions don’t seem to be working in the current bits when you are using Url extensions in a base address. As far as I could see, ASP.NET intercepts the request first and tries to route the request to a registered ASP.NET Http Handler with that extension. For example, “http://localhost/ProductCatalog/products.es” does not work, but “http://localhost/ProductCatalog/products/1.es” does.

• Hosted bug tracking system with mercurial repositories (Summary of options & request for opinions)

  - by Mark Booth

  The Question What hosted mercurial repository/bug tracking system or systems have you used? Would you recommend it to others? Are there serious flaws, either in the repository hosting or the bug tracking features that would make it difficult to recommend it? Do you have any other experiences with it or opinions of it that you would like to share? If you have used other non mercurial hosted repository/bug tracking systems, how does it compare? (If I understand correctly, the best format for this type of community-wiki style question is one answer per option, if you have experienced if several) Background I have been looking into options for setting up a bug/issue tracking database and found some valuable advice in this thread and this. But then I got to thinking that a hosted solution might not only solve the problem of tracking bugs, but might also solve the problem we have accessing our mercurial source code repositories while at customer sites around the world. Since we currently have no way to serve mercurial repositories over ssl, when I am at a customer site I have to connect my laptop via VPN to my work network and access the mercurial repositories over a samba share (even if it is just to synce twice a day). This is excruciatingly slow on high latency networks and can be impossible with some customers' firewalls. Even if we could run a TRAC or Redmine server here (thanks turnkey), I'm not sure it would be much quicker as our internet connection is over-stretched as it is. What I would like is for developers to be able to be able to push/pull to/from a remote repository, servicing engineers to be able to pull from a remote repository and for customers (both internal and external) to be able to submit bug/issue reports. Initial options The two options I found were Assembla and Jira. Looking at Assembla I thought the 'group' price looked reasonable, but after enquiring, found that each workspace could only contain a single repository. Since each of our products might have up to a dozen repositories (mostly for libraries) which need to be managed seperately for each product, I could see it getting expensive really quickly. On the plus side, it appears that 'users' are just workspace members, so you can have as many client users (people who can only submit support tickets and track their own tickets) without using up your user allocation. Jira only charges based on the number of users, unfortunately client users also count towards this, if you want them to be able to track their tickets. If you only want clients to be able to submit untracked issues, you can let them submit anonymously, but that doesn't feel very professional to me. More options Looking through MercurialHosting page that @Paidhi suggested, I've added the options which appear to offer private repositories, along with another that I found with a web search. Prices are as per their website today (29th March 2010). Corrections welcome in the future. Anyway, here is my summary, according to the information given on their websites: Assembla, http://www.assembla.com/, looks to be a reasonable price, but suffers only one repository per workspace, so three projects with 6 repos each would use up most of the spaces associated with a $99/month professional account (20 spaces). Bug tracking is based on Trac. Mercurial+Trac support was announced in a blog entry in 2007, but they only list SVN and Git on their Features web page. Cost: $24, $49, $99 & $249/month for 40, 40, unlimited, unlimited users and 1, 10, 20, 100 workspaces. SSL based push/pull? Website https login. BitBucket, http://bitbucket.org/plans/, is primarily a mercurial hosting site for open source projects, with SSL support, but they have an integrated bug tracker and they are cheap for private repositories. It has it’s own issues tracker, but also integrates with Lighthouse & FogBugz. Cost: $0, $5, $12, $50 & $100/month for 1, 5, 15, 25 & 150 private repositories. SSL based push/pull. No https on website login, but supports OpenID, so you can chose an OpenID provider with https login. Codebase HQ, http://www.codebasehq.com/, supports Hg and is almost as cheap as BitBucket. Cost: £5, £13, £21 & £40/month for 3, 15, 30 & 60 active projects, unlimited repositories, unlimited users (except 10 users at £5/month) and 0.5, 2, 4 & 10GB. SSL based push/pull? Website https login? Firefly, http://www.activestate.com/firefly/, by ActiveState looks interesting, but the website is a little light on details, such as whether you can only have one repository per project or not. Cost: $9, $19, & £39/month for 1, 5 & 30 private projects, with a 0.5, 1.5 & 3 GB storage limit. SSL based push/pull? Website https login. Jira, http://www.atlassian.com/software/jira/, isn’t limited by the number of repositories you can have, but by ‘user’. It could work out quite expensive if we want client users to be able to track their issues, since they would need a full user account to be created for them. Also, while there is a Mercurial extension to support jira, there is no ‘Advanced integration’ for Mercurial from Atlassian Fisheye. Cost: $150, $300, $400, $500, $700/month for 10, 25, 50, 100, 100+ users. SSL based push/pull? Website https login. Kiln & FogBugz On Demand, http://fogcreek.com/Kiln/IntrotoOnDemand.html, integrates Kilns mercurial DVCS features with FogBugz, where the combined package is much cheaper than the component parts. Also, the Fogbugz integration is supposedly excellent. *8’) Cost: £30/developer/month ($5/d/m more than either on their own). SSL based push/pull? SourceRepo, http://sourcerepo.com/, also supports HG and is even cheaper than BitBucket & Codebase. Cost: $4, $7 & $13/month for 1, unlimited & unlimited repositories/trac/redmine instances and 500MB, 1GB & 3GB storage. SSL based push/pull. Website https login. Edit: 29th March 2010 & Bounty I split this question into sections, made the questions themselves more explicit, added other options from the research I have done since my first posting and made this community wiki, since I now understand what CW is for. *8') Also, I've added a bounty to encourage people to offer their opinions. At the end of the bounty period, I will award the bounty to whoever writes the best review (good or bad), irrespective of the number of up/down votes it gets. Given that it's probably more important to avoid bad providers than find the absolute best one, 'bad reviews' could be considered more important than good ones.

• Resolving SNAPSHOT dependencies with timestamps from Ivy

  - by bradhouse

  I am attempting to resolve timestamped SNAPSHOT dependencies with Ivy. The environment is Ant + Ivy 1.2.0 + Archiva. Archiva itself is populated from Maven2 builds. Ivy is only used to resolve dependencies (from a single, non Maven2 project). How can Ivy be configured to correctly resolve timestamped artifacts from an Archiva or m2 repository?

• Ivy and Snapshots (Nexus)

  - by Uberpuppy

  Hey folks, I'm using ant, ivy and nexus repo manager to build and store my artifacts. I managed to get everything working: dependency resolution and publishing. Until I hit a problem... (of course!). I was publishing to a 'release' repo in nexus, which is locked to 'disable redeploy' (even if you change the setting to 'allow redeploy' (really lame UI there imo). You can imagine how pissed off I was getting when my changes weren't updating through the repo before I realised that this was happening. Anyway, I now have to switch everything to use a 'Snapshot' repo in nexus. Problem is that this messes up my publish. I've tried a variety of things, including extensive googling, and haven't got anywhere whatsoever. The error I get is a bad PUT request, error code 400. Can someone who has got this working please give me a pointer on what I'm missing. Many thanks, Alastair fyi, here's my config: Note that I have removed any attempts at getting snapshots to work as I didn't know what was actually (potentially) useful and what was complete guff. This is therefore the working release-only setup. Also, please note that I've added the XXX-API ivy.xml for info only. I can't even get the xxx-common to publish (and that doesn't even have dependencies).

• java: how to get a string representation of a compressed byte array ?

  - by Guillaume

  I want to put some compressed data into a remote repository. To put data on this repository I can only use a method that take the name of the resource and its content as a String. (like data.txt + "hello world"). The repository is moking a filesystem but is not, so I can not use File directly. I want to be able to do the following: client send to server a file 'data.txt' server compress 'data.txt' into a compressed file 'data.zip' server send a string representation of data.zip to the repository repository store data.zip client download from repository data.zip and his able to open it with its favorite zip tool The problem arise at step 3 when I try to get a string representation of my compressed file. Here is a sample class, using the zip*stream and that emulate the repository showcasing my problem. The created zip file is working, but after its 'serialization' it's get corrupted. (the sample class use jakarta commons.io ) Many thanks for your help. package zip; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.util.zip.ZipEntry; import java.util.zip.ZipInputStream; import java.util.zip.ZipOutputStream; import org.apache.commons.io.FileUtils; /** * Date: May 19, 2010 - 6:13:07 PM * * @author Guillaume AME. */ public class ZipMe { public static void addOrUpdate(File zipFile, File ... files) throws IOException { File tempFile = File.createTempFile(zipFile.getName(), null); // delete it, otherwise you cannot rename your existing zip to it. tempFile.delete(); boolean renameOk = zipFile.renameTo(tempFile); if (!renameOk) { throw new RuntimeException("could not rename the file " + zipFile.getAbsolutePath() + " to " + tempFile.getAbsolutePath()); } byte[] buf = new byte[1024]; ZipInputStream zin = new ZipInputStream(new FileInputStream(tempFile)); ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFile)); ZipEntry entry = zin.getNextEntry(); while (entry != null) { String name = entry.getName(); boolean notInFiles = true; for (File f : files) { if (f.getName().equals(name)) { notInFiles = false; break; } } if (notInFiles) { // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(name)); // Transfer bytes from the ZIP file to the output file int len; while ((len = zin.read(buf)) > 0) { out.write(buf, 0, len); } } entry = zin.getNextEntry(); } // Close the streams zin.close(); // Compress the files if (files != null) { for (File file : files) { InputStream in = new FileInputStream(file); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(file.getName())); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file } tempFile.delete(); out.close(); } public static void main(String[] args) throws IOException { final String zipArchivePath = "c:/temp/archive.zip"; final String tempFilePath = "c:/temp/data.txt"; final String resultZipFile = "c:/temp/resultingArchive.zip"; File zipArchive = new File(zipArchivePath); FileUtils.touch(zipArchive); File tempFile = new File(tempFilePath); FileUtils.writeStringToFile(tempFile, "hello world"); addOrUpdate(zipArchive, tempFile); //archive.zip exists and contains a compressed data.txt that can be read using winrar //now simulate writing of the zip into a in memory cache String archiveText = FileUtils.readFileToString(zipArchive); FileUtils.writeStringToFile(new File(resultZipFile), archiveText); //resultingArchive.zip exists, contains a compressed data.txt, but it can not //be read using winrar: CRC failed in data.txt.

• git | error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied [SOLVED]

  - by Corbin Tarrant

  I am having a strange issue that I can't seem to resolve. Here is what happend: I had some log files in a github repository that I didn't want there. I found this script that removes files completely from git history like so: #!/bin/bash set -o errexit # Author: David Underhill # Script to permanently delete files/folders from your git repository. To use # it, cd to your repository's root and then run the script with a list of paths # you want to delete, e.g., git-delete-history path1 path2 if [ $# -eq 0 ]; then exit 0are still fi # make sure we're at the root of git repo if [ ! -d .git ]; then echo "Error: must run this script from the root of a git repository" exit 1 fi # remove all paths passed as arguments from the history of the repo files=$@ git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch $files" HEAD # remove the temporary history git-filter-branch otherwise leaves behind for a long time rm -rf .git/refs/original/ && git reflog expire --all && git gc --aggressive --prune I, of course, made a backup first and then tried it. It seemed to work fine. I then did a git push -f and was greeted with the following messages: error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied error: Cannot update the ref 'refs/remotes/origin/master'. Everything seems to have pushed fine though, because the files seem to be gone from the GitHub repository, if I try and push again I get the same thing: error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied error: Cannot update the ref 'refs/remotes/origin/master'. Everything up-to-date EDIT $ sudo chgrp {user} .git/logs/refs/remotes/origin/master $ sudo chown {user} .git/logs/refs/remotes/origin/master $ git push Everything up-to-date Thanks! EDIT Uh Oh. Problem. I've been working on this project all night and just went to commit my changes: error: Unable to append to .git/logs/refs/heads/master: Permission denied fatal: cannot update HEAD ref So I: sudo chown {user} .git/logs/refs/heads/master sudo chgrp {user} .git/logs/refs/heads/master I try the commit again and I get: error: Unable to append to .git/logs/HEAD: Permission denied fatal: cannot update HEAD ref So I: sudo chown {user} .git/logs/HEAD sudo chgrp {user} .git/logs/HEAD And then I try the commit again: 16 files changed, 499 insertions(+), 284 deletions(-) create mode 100644 logs/DBerrors.xsl delete mode 100644 logs/emptyPHPerrors.php create mode 100644 logs/trimXMLerrors.php rewrite public/codeCore/Classes/php/DatabaseConnection.php (77%) create mode 100644 public/codeSite/php/init.php $ git push Counting objects: 49, done.

• Hosting Mercurial on IIS7

  - by Lasse V. Karlsen

  Note, this might perhaps be best suited on serverfault.com, but since it is about hosting a programmer source code repository, I am not entirely sure. I'm posting here first, trusting that it'll be migrated if necessary. I'm attempting to host clones of my Mercurial repositories on my own server (I have the main repo somewhere else), and I'm attempting to set up Mercurial under IIS. I followed the guide here, but I get an error message. Solved: See bottom of this question for details. The error message is: mercurial.error.RepoError: repository /path/to/repo/or/config not found Here's what I did. I installed Mercurial 1.5.2 I created c:\inetpub\hg I downloaded the hg source as per the instructions of the webpage, and copied the hgweb.cgi file into c:\inetpub\hg (note, the webpage says hgwebdir.cgi, but this particular file does not exist, hgweb.cgi does, however, can this be the source of the problem?) I added a hgweb.config, with the following contents: [paths] repo1 = C:/hg/** [web] style = monoblue I created c:\hg, created a sub-directory test, and created a repository inside it I installed python 2.6.5, latest 2.6 version from the website (the webpage mentions I need to install the correct version or I'll get a specific error message, since I don't get an error message that looks remotely like the one mentioned, I assume that 2.6.5 is not the problem) I added a new virtual host hg.vkarlsen.no, pointing it to c:\inetpub\hg For this host, I added a script mapping under the Handler Mappings section, mapping *.cgi to c:\python26\python.exe -u %s %s as per the instructions on the website. I then tested it by navigating to http://hg.vkarlsen.no/hgweb.cgi, but I get an error message. To make it easier to test, I dropped to a command prompt, navigated to c:\inetpub\hg, and executed the following command (error message is part of the text below): C:\inetpub\hg>c:\python26\python.exe -u hgweb.cgi Traceback (most recent call last): File "hgweb.cgi", line 16, in <module> application = hgweb(config) File "mercurial\hgweb\__init__.pyc", line 12, in hgweb File "mercurial\hgweb\hgweb_mod.pyc", line 30, in __init__ File "mercurial\hg.pyc", line 82, in repository File "mercurial\localrepo.pyc", line 2221, in instance File "mercurial\localrepo.pyc", line 62, in __init__ mercurial.error.RepoError: repository /path/to/repo/or/config not found Does anyone know what I need to look at in order to fix this? Edit: Ok, I think I managed to get one step closer to the solution, but I'm still stumped. I realized the .cgi file is a python script file, and not something compile, so I opened it for editing, and these lines was sitting in it: # Path to repo or hgweb config to serve (see 'hg help hgweb') config = "/path/to/repo/or/config" So this was my source for the specific error message. If I change the line to this: config = "c:\\hg\\test" Then I can navigate the empty repository through the Mercurial web interface. However, I want to host multiple repositories, and seeing as the line says that I can also link to a hgweb config file, I tried this: config = "c:\\inetpub\\hg\\hgweb.config" But then I get the following error message: mercurial.error.Abort: c:\inetpub\hg\hgweb.config: not a Mercurial bundle file Exception ImportError: 'No module named shutil' in <bound method bundlerepository.__del__ of <mercurial.bundlerepo.bundlerepository object at 0x0260A110>> ignored Nothing I've tried for the config variable seems to work: config = "hgweb.config" config = "c:\\hg\\hgweb.config" various other variations I don't remember. So, still stumped, pointers anyone? Solved: I ended up having to edit the hgweb.cgi file: from: from mercurial.hgweb import hgweb, wsgicgi application = hgweb(config) to: from mercurial.hgweb import hgweb, hgwebdir, wsgicgi application = hgwebdir(config) Note the added hgwebdir parts there. Here's my hgweb.config file, located in the same directory as hgweb.cgi file: [collections] C:/hg/ = C:/hg/ [web] style = gitweb This now serves my repositories successfully. Hopefully this question will give others some information if they're stumped as I was.

• IIS7 URL Rewrite - Rewrite CSS files

  - by user1231958

  I'm trying to rewrite certain CSS files with some rules, so it replaces every single instance of links in the CSS (as in background: url("/myuri.jpg")) with a prefix (as in background: url("/zeus/myuri.jpg")) These are the rules. <rule name="ReverseProxyOutboundRule2" preCondition="IsCSS" enabled="true" stopProcessing="false"> <match filterByTags="None" pattern="url\(&quot;(.*)&quot;\)" /> <action type="Rewrite" value="url(&quot;/zeus{R:1}&quot;)" /> <conditions> <add input="{URL}" pattern="/zeus" /> </conditions> </rule> <preCondition name="IsCSS"> <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/css" /> </preCondition> However, only one url is being replaced this way and somehow the rest is being ignored. Thank you beforehand.

• Problem Implementing StructureMap in VB.Net Conversion of SharpArchitecture

  - by Monkeeman69

  I work in a VB.Net environment and have recently been tasked with creating an MVC enviroment to use as a base to work from. I decided to convert the latest SharpArchitecture release (Q3 2009) into VB, which on the whole has gone fine after a bit of hair pulling. I came across a problem with Castle Windsor where my custom repository interface (lives in the core/domain project) that was reference in the constructor of my test controller was not getting injected with the concrete implementation (from the data project). I hit a brick wall with this so basically decided to switch out Castle Windsor for StructureMap. I think I have implemented this ok as everything compiles and runs and my controller ran ok when referencing a custom repository interface. It appears now that I have/or cannot now setup my generic interfaces up properly (I hope this makes sense so far as I am new to all this). When I use IRepository(Of T) (wanting it to be injected with a concrete implementation of Repository(Of Type)) in the controller constructor I am getting the following runtime error: "StructureMap Exception Code: 202 No Default Instance defined for PluginFamily SharpArch.Core.PersistenceSupport.IRepository`1[[DebtRemedy.Core.Page, DebtRemedy.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], SharpArch.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b5f559ae0ac4e006" Here are my code excerpts that I am using (my project is called DebtRemedy).

• Error pushing to remote with git

  - by pcm2a

  I have a fresh Centos 6 server stood up and I have installed git version 1.7.1 through yum. I am using the smart http method through apache for access. When I try to push to the remote server this is what I get: $ git push origin master Password: Counting objects: 6, done. Compressing objects: 100% (3/3), done. Writing objects: 100% (6/6), 436 bytes, done. Total 6 (delta 0), reused 0 (delta 0) error: unpack failed: index-pack abnormal exit I have tried these things which made no difference: chown -R apache:apache /path/to/git/repository (httpd runs as apache) chown -R apache:users /path/to/git/repository chmod -R 777 /path/to/git/repository (obviously not secure but wanted to eliminate this being a file permission problem) What can I try to get pushing to work?

• Mac OS X Server add server user

  - by Meltemi

  What's the recommended way to add a user to Mac OS X Server that doesn't need all the hoopla associated with Workgroup Manager? There are many users pre-configured in Mac OS X Server (www, root, ldapadmin, etc.) that don't have "Full Name" or mail accounts, etc. I'd like to create a 'svn' user to be the owner of our Subversion Repository as per this tutorial: If you've decided to use either Apache or stock svnserve, create a single svn user on your system and run the server process as that user. Be sure to make the repository directory wholly owned by the svn user as well. From a security point of view, this keeps the repository data nicely siloed and protected by operating system filesystem permissions, changeable by only the Sub- version server process itself. Wondering if there's a way outside of WorkgroupManager and OpenDirectory as this account will be entirely server based. Is this still sound advice under OS X Server? If so what's the easiest way to create the user (Mac OS X Server doesn't seem to respond to useradd).
