  • playing a dvd using C#

    - by user203212
    Hi, I have a dvd copied in my hard drive. It has a folder called video_ts. I am planning to run VLC player to play it. i was wondering how can I play this dvd using c#. I do not want to use a activex control inside c#. All I need to do is run the vlc.exe using process. I have already done that. But how do I select a specific file from the code that will start playig in the vlc player. My code is. System.Diagnostics.Process Proc = new System.Diagnostics.Process(); Proc.StartInfo.FileName = @"C:\Program Files\VideoLAN\VLC\vlc.exe"; Proc.StartInfo.Arguments = @"C:\Test\Legacy\VIDEO_TS\VIDEO_TS.BUP"; Proc.Start(); I am trying to send the file name as a argument to run it in the vlc.exe . But its not working. Its just opening up the vlc player. I dont want the user to select the file manually.

  • Installing Ruby via rbenv fails

    - by Maximus S
    Problem: I installed ruby, but it is not recognized correctly. I'm following the deploying to VPS: https://github.com/railscasts/335-deploying-to-a-vps I am setting my server on ubuntu 12.04 LTS to deploy my rails app. I'm following the railscast on deploying to a VPS, and trying to install ruby through rbenv.

  • Powershell 2.0 Hang When Run From MsDeploy pre- post- ops using c/

    - by SonOfNun
    I am trying to invoke powershell during the preSync call in a MSDeploy command, but powershell does not exit the process after it has been called. The command (from command line): "tools/MSDeploy/msdeploy.exe" -verb:sync -preSync:runCommand="powershell.exe -NoLogo -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -Command C:/MyInstallPath/deploy.ps1 Set-WebAppOffline Uninstall-Service ",waitInterval=60000 -usechecksum -source:dirPath="build/for-deployment" -dest:wmsvc=BLUEPRINT-X86,username=deployer,password=deployer,dirPath=C:/MyInstallPath I used a hack here (http://therightstuff.de/2010/02/06/How-We-Practice-Continuous-Integration-And-Deployment-With-MSDeploy.aspx) that gets the powershell process and kills it but that didn't work. I also tried taskkill and the sysinternals equivalent, but nothing will kill the process so that MSDeploy errors out. The command is executed, but then just sits there. Any ideas what might be causing powershell to hang like this? I have found a few other similar issues around the web but no answers. Environment is Win 2K3, using Powershell 2.0. UPDATE: Here is a .vbs script I use to invoke my powershell command now. Invoke using 'cscript.exe path/to/script.vbs': Option Explicit Dim oShell, appCmd,oShellExec Set oShell = CreateObject("WScript.Shell") appCmd = "powershell.exe -NoLogo -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -Command ""&{ . c:/development/materialstesting/deploy/web/deploy.ps1; Set-WebAppOffline }"" " Set oShellExec = oShell.Exec(appCmd) oShellExec.StdIn.Close()

  • Writing/Reading struct w/ dynamic array through pipe in C

    - by anrui
    I have a struct with a dynamic array inside of it: struct mystruct{ int count; int *arr; }mystruct_t; and I want to pass this struct down a pipe in C and around a ring of processes. When I alter the value of count in each process, it is changed correctly. My problem is with the dynamic array. I am allocating the array as such: mystruct_t x; x.arr = malloc( howManyItemsDoINeedToStore * sizeof( int ) ); Each process should read from the pipe, do something to that array, and then write it to another pipe. The ring is set up correctly; there's no problem there. My problem is that all of the processes, except the first one, are not getting a correct copy of the array. I initialize all of the values to, say, 10 in the first process; however, they all show up as 0 in the subsequent ones. for( j = 0; j < howManyItemsDoINeedToStore; j++ ){ x.arr[j] = 10; } Initally: 10 10 10 10 10 After Proc 1: 9 10 10 10 15 After Proc 2: 0 0 0 0 0 After Proc 3: 0 0 0 0 0 After Proc 4: 0 0 0 0 0 After Proc 5: 0 0 0 0 0 After Proc 1: 9 10 10 10 15 After Proc 2: 0 0 0 0 0 After Proc 3: 0 0 0 0 0 After Proc 4: 0 0 0 0 0 After Proc 5: 0 0 0 0 0 Now, if I alter my code to, say, struct mystruct{ int count; int arr[10]; }mystruct_t; everything is passed correctly down the pipe, no problem. I am using READ and WRITE, in C: write( STDOUT_FILENO, &x, sizeof( mystruct_t ) ); read( STDIN_FILENO, &x, sizeof( mystruct_t ) ); Any help would be appreciated. Thanks in advance!

  • AnyCPU/x86/x64 for C# application and it's C++/CLI dependency

    - by Soonts
    I'm Windows developer, I'm using Microsoft visual studio 2008 SP1. My developer machine is 64 bit. The software I'm currently working on is managed .exe written in C#. Unfortunately, I was unable to solve the whole problem solely in C#. That's why I also developed a small managed DLL in C++/CLI. Both projects are in the same solution. My C# .exe build target is "Any CPU". When my C++ DLL build target is "x86", the DLL is not loaded. As far as I understood when I googled, the reason is C++/CLI language, unlike other .NET languages, compiles to the native code, not managed code. I switched the C++ DLL build target to x64, and everything works now. However, AFAIK everything will stop working as soon as my client will install my product on a 32-bit OS. I have to support Windows Vista and 7, both 32 and 64 bit versions of each of them. I don't want to fall back to 32 bits. That 250 lines of C++ code in my DLL is only 2% of my codebase. And that DLL is only used in several places, so in the typical usage scenario it's not even loaded. My DLL implements two COM objects with ATL, so I can't use "/clr:safe" project setting. Is there way to configure the solution and the projects so that C# project builds "Any CPU" version, the C++ project builds both 32 bit and 64 bit versions, then in the runtime when the managed .EXE is starting up, it uses either 32-bit DLL or 64-bit DLL depending on the OS? Or maybe there's some better solution I'm not aware of? Thanks in advance!

  • How to perform a binary search on IList<T>?

    - by Daniel Brückner
    Simple question - given an IList<T> how do you perform a binary search without writing the method yourself and without copying the data to a type with build-in binary search support. My current status is the following. List<T>.BinarySearch() is not a member of IList<T> There is no equivalent of the ArrayList.Adapter() method for List<T> IList<T> does not inherit from IList, hence using ArrayList.Adapter() is not possible I tend to believe that is not possible with build-in methods, but I cannot believe that such a basic method is missing from the BCL/FCL. If it is not possible, who can give the shortest, fastest, smartest, or most beatiful binary search implementation for IList<T>? UPDATE We all know that a list must be sorted before using binary search, hence you can assume that it is. But I assume (but did not verify) it is the same problem with sort - how do you sort IList<T>? CONCLUSION There seems to be no build-in binary search for IList<T>. One can use First() and OrderBy() LINQ methods to search and sort, but it will likly have a performance hit. Implementing it yourself (as an extension method) seems the best you can do.

  • How can I work out what events are being waited for with WinDBG in a kernel debug session

    - by Benj
    I'm a complete WinDbg newbie and I've been trying to debug a WindowsXP problem that a customer has sent me where our software and some third party software prevent windows from logging off. I've reproduced the problem and have verified that only when our software and the customers software are both installed (although not necessarily running at logoff) does the log off problem occur. I've observed that WM_ENDSESSION messages are not reaching the running windows when the user tries to log off and I know that the third party software uses a kernel driver. I've been looking at the processes in WinDbg and I know that csrss.exe would normally send all the windows a WM_ENDSESSION message. When I ran: !process 82356020 6 To look at csrss.exe's stack I can see: WARNING: Frame IP not in any known module. Following frames may be wrong. 00000000 00000000 00000000 00000000 00000000 0x7c90e514 THREAD 8246d998 Cid 0248.02a0 Teb: 7ffd7000 Win32Thread: e1627008 WAIT: (WrUserRequest) UserMode Non-Alertable 8243d9f0 SynchronizationEvent 81fe0390 SynchronizationEvent Not impersonating DeviceMap e1004450 Owning Process 82356020 Image: csrss.exe Attached Process N/A Image: N/A Wait Start TickCount 1813 Ticks: 20748 (0:00:05:24.187) Context Switch Count 3 LargeStack UserTime 00:00:00.000 KernelTime 00:00:00.000 Start Address 0x75b67cdf Stack Init f80bd000 Current f80bc9c8 Base f80bd000 Limit f80ba000 Call 0 Priority 14 BasePriority 13 PriorityDecrement 0 DecrementCount 0 Kernel stack not resident.

Can anyone tell me how I might find out what event it's waiting for anything else I might do to further investigate the problem?

  • Emulating Visual Studio's Web Application "publish" at the command line

    - by cbp
    Hi, I am trying to automate my deployment process and am now thoroughly confused. I know that there are many questions on stackoverflow about this, but they all have different solutions and none of them work. I have a Web Application project which I usually publish by right-clicking and selecting "Publish". I get a dialog box where I use the following options: Build configuration: Release Publish method: File system Target location: C:\Deployments\MyWebsite Replace matching files with local copies I should mention that in the properties of the project I have "Items to deploy" set to "Only files needed to run this application". After running this, my entire solution is built, dependencies are resolved, build events are run, web.config transformations are applied and the website is copied to C:\Deployments\MyWebsite, although non-required files such as code-behind files are not copied. I have not been able to replicate this... in fact at this stage I'm not even sure which command line tool am I supposed to be using - msbuild, msdeploy or aspnet_compiler? This guy asks almost the same question but his solution doesn't work at all. For example, build events do not run correctly because the macros are not resolved. Whats more, the files do not get copied into the correct directory at all... I can't even begin to explain what happens!

  • Rails running multiple delayed_job - lock tables

    - by pepernik
    Hey. I use delayed_job for background processing. I have 8 CPU server, MySQL and I start 7 delayed_job processes RAILS_ENV=production script/delayed_job -n 7 start Q1: I'm wondering is it possible that 2 or more delayed_job processes start processing the same process (the same record-row in the database delayed_jobs). I checked the code of the delayed_job plugin but can not find the lock directive in a way it should be. I think each process should lock the database table before executing an UPDATE on lock_by column. They lock the record simply by updating the locked_by field (UPDATE delayed_jobs SET locked_by...). Is that really enough? No locking needed? Why? I know that UPDATE has higher priority than SELECT but I think this does not have the effect in this case. My understanding of the multy-threaded situation is: Process1: Get waiting job X. [OK] Process2: Get waiting jobs X. [OK] Process1: Update locked_by field. [OK] Process2: Update locked_by field. [OK] Process1: Get waiting job X. [Already processed] Process2: Get waiting jobs X. [Already processed] I think in some cases more jobs can get the same information and can start processing the same process. Q2: Is 7 delayed_jobs a good number for 8CPU server? Why yes/not. Thx 10x!

  • Swimlane Diagram Softwares with Expand/Collapse Features

    - by louis xie
    I've been searching real hard for a software which can fulfill my needs, but to no avail. I have a swimlane diagram which is extremely huge, and almost impossible to model using Visio or any traditional swimlane software. I would need to model both the operational process, as well as the interactions within an application and between different applications. Therefore, without wasting additional effort modelling these separately, I am looking for a solution which I can combine both views together. That is, possibly one which I can expand/collapse/group/ungroup processes/subprocesses together. Take a typical credit card process for instance, a hypothetical description of the swimlane could be as such: Customer submits application form to the bank Bank Officer A receives the application form and validates that it was correctly filled Bank Officer A submits application form to Bank Officer B for processing. Bank Officer B checks credit quality of the customer through Application X. Application X submits query to Application Y to retrieve Credit Report. Application X retrieves credit report and submits to Application Z for computation of credit scores Bank Officer B validates that customer is credit worthy, and submits application to Bank Officer C for processing. The above is an over-simplified credit card request process, and a purely hypothetical one. What I'm trying to drive at is, each of the above processes have sub-processes, and I want to be able to switch between a "detailed" view and "aggregated" view. If possible, add in time dependency of the different tasks, as well. I haven't been able to find one such software which could do this.

  • SQL UNION ALL with a INNER JOIN

    - by kOhm
    I'm looking for the best way to display all rows from two tables while joining first by one field (dwg) then where applicable a 2nd join on part. Table1 data consists of schematics(dwg) along with a list of parts required to build the item depicted in the drawing. Table2 consists of data about the actual parts ordered to build the schematic. Some parts in table2 are a combination of parts in table1 (ex: foo and bar in table1 were ordered as foobar in table2). I can display all rows in both tables with UNION ALL, but this doesn't join on both the dwg and part fields. I looked at FULL OUTER JOIN also, but I haven't figured out how to join first by dwg, then by part. Here is an example of the data. table1 table2 dwg part qty order dwg part qty ----- ----- ----- ----- ----- ----- ----- 123 foo 1 ord1 123 foobar 1 123 bar 1 ord1 123 bracket 2 123 widget 2 ord2 123 screw 4 123 bracket 4 ord2 123 nut 4 456 foo 1 ord2 123 widget 2 ord2 123 bracket 2 ord3 456 foo 1 Desired output: The goal is to create a view that provides visibility to all parts in table1 and the associated orders in table2 (including those parts that appear in one but not the other table) so that I can see all the drawing parts in table1 and the associated records in table2 along with records in table2 where the part wasn't in table1. part_request_order_report dwg part qty order part qty ----- ----- ----- ------ ----- ----- 123 foo 1 123 bar 1 123 widget 2 ord2 widget 2 123 bracket 4 ord1 bracket 2 123 bracket 4 ord2 bracket 2 123 ord1 foobar 1 123 ord1 screw 4 123 ord1 nut 4 456 foo 1 ord3 foo 1 Is this possible? Or am I better off iterating through the data to build the report table? Thanks in advance.

  • Linux time sample based profiler.

    - by Caspin
    short version: Is there a good time based sampling profiler for Linux? long version: I generally use OProfile to optimize my applications. I recently found a shortcoming that has me wondering. The problem was a tight loop spawning c++filt to demangle a c++ name. I only stumbled upon the code by accident while chasing down another bottleneck. The OProfile didn't show anything unusual about the code so I almost ignored it but my code sense told me to optimize the call and see what happened. I changed the popen of c++filt to abi::__cxa_demangle. The runtime went from more than a minute to a little over a second. About a x60 speed up. Is there a way I could have configured OProfile to flag the popen call? As the profile data sits now OProfile thinks the bottle neck was the heap and std::string calls (which BTW once optimized dropped the runtime to less than a second, more than x2 speed up). Here is my OProfile configuration: $ sudo opcontrol --status Daemon not running Event 0: CPU_CLK_UNHALTED:90000:0:1:1 Separate options: library vmlinux file: none Image filter: /path/to/excutable Call-graph depth: 7 Buffer size: 65536 Is there another profiler for Linux that could have found the bottleneck? I suspect the issue is that OProfile only logs its samples to the currently running process. I'd like it to always log its samples to the process I'm profiling. So if the process is currently switched out (blocking on IO or a popen call) OProfile would just place its sample at the blocked call. If I can't fix this, OProfile will only be useful when the executable is pushing near 100% CPU. It can't help with executables that that have inefficient blocking calls.

  • Game architecture: modeling different steps/types of UI

    - by Sander
    I have not done any large game development projects, only messed around with little toy projects. However, I never found an intuitive answer to a specific design question. Namely, how are different types/states of UI modeled in games? E.g. how is a menu represented? How is it different from a "game world" state (let's use an FPS as an example). How is an overlaid menu on top of a "game world" modeled? Let's imagine the main loop of a game. Where do the game states come into play? It it a simple case-by-case approach? if (menu.IsEnabled) menu.Process(elapsedTime); if (world.IsEnabled) world.Process(elapsedTime); if (menu.IsVisible) menu.Draw(); if (world.IsVisible) world.Draw(); Or are menu and world represented somewhere in a different logic layer and not represented at this level? (E.g. a menu is just another high-level entity like e.g. player input or enemy manager, equal to all others) foreach (var entity in game.HighLevelEntities) entity.Process(elapsedTime); foreach (var entity in game.HighLevelEntities) entity.Draw(elapsedTime); Are there well-known design patterns for this? Come to think of it, I don't know any game-specific design patterns - I assume there are others, as well? Please tell me about them.

  • How to hand-over a TCP listening socket with minimal downtime?

    - by Shtééf
    While this question is tagged EventMachine, generic BSD-socket solutions in any language are much appreciated too. Some background: I have an application listening on a TCP socket. It is started and shut down with a regular System V style init script. My problem is that it needs some time to start up before it is ready to service the TCP socket. It's not too long, perhaps only 5 seconds, but that's 5 seconds too long when a restart needs to be performed during a workday. It's also crucial that existing connections remain open and are finished normally. Reasons for a restart of the application are patches, upgrades, and the like. I unfortunately find myself in the position that, every once in a while, I need to do this kind of thing in production. The question: I'm looking for a way to do a neat hand-over of the TCP listening socket, from one process to another, and as a result get only a split second of downtime. I'd like existing connections / sockets to remain open and finish processing in the old process, while the new process starts servicing new connectinos. Is there some proven method of doing this using BSD-sockets? (Bonus points for an EventMachine solution.) Are there perhaps open-source libraries out there implementing this, that I can use as is, or use as a reference? (Again, non-Ruby and non-EventMachine solutions are appreciated too!)

  • Check if file is locked or catch error for trying to open

    - by Duncan Matheson
    I'm trying to handle the problem where a user can try to open, with an OpenFileDialog, a file that is open by Excel. Using the simple FileInfo.OpenRead(), it chucks an IOException, "The process cannot access the file 'cakes.xls' because it is being used by another process." This would be fine to display to the user except that the user will actually get "Debugging resource strings are unavailable" nonsense. It seems not possible to open a file that is open by another process, since using FileInfo.Open(FileMode.Open, FileAccess.Read, FileShare.ReadWrite) chucks a SecurityException, "File operation not permitted. Access to path 'C:\whatever\cakes.xls' is denied.", for any file. Rather unhelpful. So it's down to either finding some way of checking if the file is locked, or trying to catch the IOException. I don't want to catch all IOExceptions and assume they're all locked file errors, so I need some sort of way of classifying this type of exception as this error... but the "Debugging resource strings" nonsense along with the fact that that message itself is probably localized makes it tricky. I'm partial trust, so I can't use Marshal.GetHRForException. So: Is there any sensible way of either check if a file is locked, or at least determining if this problem occurred without just catching all IOExceptions?

  • How to find Tomcat's PID and kill it in python?

    - by 4herpsand7derpsago
    Normally, one shuts down Apache Tomcat by running its shutdown.sh script (or batch file). In some cases, such as when Tomcat's web container is hosting a web app that does some crazy things with multi-threading, running shutdown.sh gracefully shuts down some parts of Tomcat (as I can see more available memory returning to the system), but the Tomcat process keeps running. I'm trying to write a simple Python script that: Calls shutdown.sh Runs ps -aef | grep tomcat to find any process with Tomcat referenced If applicable, kills the process with kill -9 <PID> Here's what I've got so far (as a prototype - I'm brand new to Python BTW): #!/usr/bin/python # Imports import sys import subprocess # Load from imported module. if __init__ == "__main__": main() # Main entry point. def main(): # Shutdown Tomcat shutdownCmd = "sh ${TOMCAT_HOME}/bin/shutdown.sh" subprocess.call([shutdownCmd], shell=true) # Check for PID grepCmd = "ps -aef | grep tomcat" grepResults = subprocess.call([grepCmd], shell=true) if(grepResult.length > 1): # Get PID and kill it. pid = ??? killPidCmd = "kill -9 $pid" subprocess.call([killPidCmd], shell=true) # Exit. sys.exit() I'm struggling with the middle part - with obtaining the grep results, checking to see if their size is greater than 1 (since grep always returns a reference to itself, at least 1 result will always be returned, methinks), and then parsing that returned PID and passing it into the killPidCmd. Thanks in advance!

  • Graceful DOS Command Error-Handling

    - by Captain Obvious
    PHP 5.2.13 on Windows 2003 I am using the DOS Start /B command to launch a background application using the PHP popen() function: popen("start /B {$_SERVER['HOMEPATH']}/{$app}.exe > {$_SERVER['HOMEPATH']}/bg_output.log 2>&1 & echo $!", 'r'); The popen() function launches a cmd.exe process that runs the specified command; however, if the command fails (e.g. the {$app}.exe doesn't exist or is locked in the above example), the cmd.exe process never returns, and PHP hangs indefinitely as a result. Calling the failing DOS command directly using the Command Prompt results in an Error prompt that requires clicking the OK button. I assume this error confirmation requirement is what's preventing the cmd.exe process from returning to PHP both from the Command Prompt (using both CGI and CLI) and the web (using Apache 2.0 handler w/Apache 2.2). Is there a way to write the DOS command or configure the server or cmd.exe app itself to return the DOS error to the originating call rather than waiting for confirmation?

  • Automated Legal Processing

    - by Chris S
    Will it ever be possible to make legal systems quantifiable enough to process with computer algorithms? What technologies would have to be in place before this is possible? Are there any existing technologies that are already trying to accomplish this? Out of curiosity, I downloaded the text for laws in my local municipality, and tried applying some simple NLP tricks to extract rules from sentences. I had mixed results. Some sentences were very explicit (e.g. "Cars may not be left in the park overnight"), but other sentences seemed hopelessly vague (e.g. "The council's purpose is to ensure the well-being of the community"). I apologize if this is too open-ended a topic, but I've often wondered what society would look like if legal systems were based on less ambiguous language. Lawyers, and the legal process in general, are so expensive because they have to manually process a complex set of rules codified in ambiguous legal texts. If this system could be represented in software, this huge expense could potentially be eliminated, making the legal system more accessible for everyone.

  • Errors with redefinitions after upgrade to XCode 3.2.3

    - by CA Bearsfan
    I recently upgraded to Snow Leopard and Xcode 3.2.5 so I could test on my iPod Touch and iPhone and ran into some problems with the project I was working on. First it couldn't find a Base SDK, then my old frameworks weren't hooking up correctly. Finally after setting the Project Format to Xcode 3.1 compatible (3.2 also worked) and the Base SDK for all configurations to iOS 4.2, then setting my iOS deployment target to iOS 3.0 I was able to get the system to find a Base SDK and attempt a build. That's when the frameworks didn't want to cooperate. 4/6 I'm using displayed in red, so I re routed the path to the iPhone simulator 4.2 platform which worked perfectly. I was able to build my project, no errors or warnings and my app worked fine. I went to work last night thinking I had fixed the problem. This morning I fired up the laptop and went to build my code base and now have 1142 errors all of which have to do with code I haven't written deemed as being redefined. Suggestions? The following is just a small sample of the error list (obviously don't need to see all 1142) //Frameworks/Foundation.framework/Headers/NSZone.h:48: error: redefinition of 'NSMakeCollectable' /Frameworks/Foundation.framework/Headers/NSObject.h:65: error: duplicate interface declaration for class 'NSObject' /Frameworks/Foundation.framework/Headers/NSObject.h:67: error: redefinition of 'struct NSObject'

  • Unable to create a breakpoint in Eclipse and Tomcat

    - by Traroth
    Since yesterday, I get a strange error message when I start my Tomcat (6.0.35) under Eclipse Juno (build 20120614-1722): Among the things I tried in order to get rid of the error: Check in Preferences - Java - Compiler if all "Classfile Generation" checkboxes where checked. I did that for both general preferences and project preference Uncheck them, build, check them build again (found on another question) Add org.eclipse.jdt.core.compiler.debug.lineNumber=generate to my .settings/org.eclipse.jdt.core.prefs file Use a new CVS checkout (same symptoms) And now, I don't know what to do anymore. The problem is really stopping me from get anything done. I can't work anymore. Crazy is: the problem doesn't happen on every class, only on some of them. Neither does it happen on my other Eclipse projects. And it didn't happen before yesterday, even if I can't remeber having done anything weird. Actually, I have never seen a problem like this in almost 10 years I'm using Eclipse... If you have any idea, I would be really grateful... Edit: I also tried to ignore the message and go on with my tests: If I create another breakpoint upstream from my problematic class, when I enter this problematic class, it tries to open a $Proxy132 class, which means it actually opens an empty page, with a source not found message

  • SVN marking file production ready

    - by dan.codes
    I am kind of new to SVN, I haven't used it in detail basically just checking out trunk and committing then exporting and deploying. I am working on a big project now with several developers and we are looking for the best deployment process. The one thing we are hung up on is the best way to tag, branch and so on. We are used to CVS where all you have to do is commit a file and tag it as production ready and if not that code will not get deployed. I see that SVN handles tagging differently then CVS. I figure I am looking at this and making it overly complex. It seems the only way to work on a project and commit files without it being in the production code is to do it in a branch and then merge those changes when you are ready for it to be deployed. I am assuming you could also be working on other code that should be deployed so you would have to be switching between working copies, because otherwise you are working on a branch that isn't getting mixed in with the trunk or production branch? This process seems overly complex and I was wondering if anyone could give me what you think is the best process for managing this.
