How to write self updating software

There are very few of us experts who really understand this stuff. Do not require a bootstrapper, or multi-step process. By default it will look for a file called update. Just think of the power you could give the AI to develop its own programs! NET 4. Assembly ASM is close, but still contains far too many permutations. Starting monitoring every s. The launcher can't be easily managed with Group Policy Objects or other standard software deployment tools -- you can't, for instance, manually disable its own auto-updating functionality. Both are worthy of a closer look for examples of how to deal with the rapid deployment of software updates in the enterprise. Cause This problem occurs if you manually disable updates or if updates are being managed by Group Policy settings. The Fitness Method The fitness method works by scoring the output of the generated program. All this code will do is call out to our ServiceProcess project. Introduction Is it possible for a computer program to write its own programs? The updater logic verifies the signature on the XML doc, but you may not care about that. In this model, there are three "lifecycle stages" of an app during an update. Single XML file configuration. Accommodate some simple logging. There are areas for improvement that weren't required for this project, such as: How to write self updating software



I guess it would work from console apps as well, but I have never tried it. This is where the majority of the logic will be held for the service. Each time one of the monkeys hits a correct key in the right sequence you reward him with a banana? The second, Chrome Component Updater, keeps Chrome's internal components up to date. This isn't intended for applications that reside in Program Files. To examine the registry data that is associated with the Group Policy settings that control this feature, follow these steps: Firefox, on the other hand, has long been uninterested in providing a tool set for deployments in organizations , and it has left a lot of that work to third parties. Conclusion It's not bad for a few hours work. The launcher can't be easily managed with Group Policy Objects or other standard software deployment tools -- you can't, for instance, manually disable its own auto-updating functionality. Serdar Yegulalp Is it something in the water? A genome consists of an array of doubles. The library is large and growing constantly -- yes, it does take suggestions -- but don't assume a given program is available. Check starting. How do we solve the chicken and egg problem? Files aren't checked for integrity i. The programming language is brainfuck.

Part 1 , Part 2 , Part 3 , and research paper. Check fetches the remote manifest, checks the SecurityToken for tampering, and compares the version of the remote manifest to that of the local one. The Fitness Method The fitness method works by scoring the output of the generated program. Eduardo Oliveira's article from looked promising, but I wanted something even simpler that could even update the updater itself. Local version is 1. Pretty simple, eh? Update creates a work directory, downloads each of the payloads specified in the remote manifest, and unzips each of them. Assembly ASM is close, but still contains far too many permutations. All this code will do is call out to our ServiceProcess project. It then runs as normal, including checking for updates. The manifests are represented by the Manifest class. While the ultimate goal would be to produce a computer program capable of writing its own word processing software, image editing tool, web browser, or disk defragmenter, I was more-so interested in a simple proof-of-concept that demonstrated the idea was possible. Deleting work directory. The service updater is a console application that will be launched when there is an update ready to be applied. How it Works The Updater class does all the heavy lifting. For example, a recent Chrome update made changes to the way Java worked, which caused at least one browser-based application I was using to no longer work correctly. Points of Interest In order to target the. To that end, it's best not to use it as part of a deployment effort. Windows Installer deployment requires administrative permissions and allows only limited user installation; ClickOnce deployment enables non-administrative users to install and grants only those Code Access Security permissions necessary for the application. Versions are the same. Disable app updates via policies The most straightforward way to deal with the problem is to disable the automatic updating of the application via a policy mechanism -- provided the application in question has one. On the File tab, click Account.

Firefox, on the other hand, has long been uninterested in providing a tool set for deployments in organizations , and it has left a lot of that work to third parties. On a Tangent to Genetic Algorithms This is the general idea behind a genetic algorithm. As humorous as it sounds, I eventually experimented with brainf-ck and was finally able to successfully generate the code shown above. Renaming running process to 'F: NET and uses an array of doubles to serve as a genome. The AI also gains access to the internal components of the interpreter, such as memory, instructions, and output. I will leave this for the reader to implement. Automatic updates managed by Group Golicy Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. Timer that ticks at the interval set by the manifest. Trying Environment. NET Framework until version 4. I have included a simple facilty for debugging, or if you wish to add a user interface to let the user know what is happening. Add a class library called ServiceProcess: You are running version 2 of this console application. The updater logic verifies the signature on the XML doc, but you may not care about that. Start any Office or Office program. Remote config is valid. Spawning new process. Startup App. Location as in the following image:

See also: Only those parts of the application that have changed are downloaded, and then the full, updated application is reinstalled from a new side-by-side folder. It starts by loading an XML manifest that supplies all of the information it needs to do its work. The score is calculated by looking at each character output by the program if any output was produced at all and subtracting its value from the desired character: You're done. Security permissions. To keep this simple, I just hard coded them. The main thread is going to wait for a keypress. Introduction Is it possible for a computer program to write its own programs? You are running version 2 of this console application. This allows us to avoid coping and pasting code to multiple projects. In the normal course, the app checks for updates, and then runs as normal. Remote version is 2. In this manner, it can execute multiple fitness algorithms for multiple genomes in the population, upon each generation. Interpreter Instruction Set Brainf-ck consists of the following instruction set: Some of these file paths and service names are hard coded for simplicity, but you may choose to pull these from the App. Check starting. As computers get faster, more computations can be performed, allowing increasing power for the computation-intensive processing required by many AI algorithms. On the File tab, click Account. Each time one of the monkeys hits a correct key in the right sequence you reward him with a banana? Start any Office or Office program. At some point the user may confirm that they want to install the available update, and the Updater downloads the app to a temporary location, then starts a process using that newly downloaded exe. Since the fitness method is the most computationally expensive part it has to execute the program code for each member in the population, which probably includes infinite loops and other nasty stuff , the AI program uses the Parallel.

It then runs as normal, including checking for updates. Predictably, Google's stance is that auto-updating is a good thing, because you might not receive the latest security updates if you disable auto-updates. Those that have the best fitness are mated together to produce offspring. The AI also gains access to the internal components of the interpreter, such as memory, instructions, and output. With Microsoft Windows Installer deployment, whenever an application is updated, the user must reinstall the whole application; with ClickOnce deployment, you can provide updates automatically. A genome consists of an array of doubles. One of the payloads might contain a replacement for your application's executable itself, but it can't be overwritten while it is running. Firefox and Chrome both have ways to do this, although they are markedly different. Points of Interest In order to target the. Each double gene in the genome corresponds to an instruction in the programming language. Mate the best genomes together using roulette selection, crossover, and mutation to produce a new generation. Eduardo Oliveira's article from looked promising, but I wanted something even simpler that could even update the updater itself. The philospohy is that update checks happen automatically, but updates are installed only after user confirmation. This allows us to avoid coping and pasting code to multiple projects. While this was interesting, the end result was simple math calculation and the programming language itself, was unknown and had severe limitations with what it could ultimately produce. NET 4. As humorous as it sounds, I eventually experimented with brainf-ck and was finally able to successfully generate the code shown above. Check ending. I only had a few hours to put something together. Remote config is valid.

Deleting work directory. This also provides security constraints, since the child programs are running within a controlled environment, within the AI program. First is that not every program you'd want to deploy is available in the app library. Meanwhile, the application continues to run without interruption in the foreground. All this code will do is call out to our ServiceProcess project. While this kind of idea seems far-fetched, it may actually be closer than we think. With Windows Installer deployment, applications often rely on shared components, with the potential for versioning conflicts; with ClickOnce deployment, each application is self-contained and cannot interfere with other applications. Update creates a work directory, downloads each of the payloads specified in the remote manifest, and unzips each of them. If you are asked whether you want to let Microsoft Office Click-to-Run make changes to your computer, click Yes. Note In Outlook, click Office Account. Flush out this class with some control properties such as Started, ReadyToExit, etc. If one were so inclined, you could write out to both locations so that the data that is written to the text file is the data that is displayed on the screen.

At present, payloads must be ZIP files and their directory structure should be relative to the application's root. Remote config is valid. There are very few of us experts who really understand this stuff. When this occurs, a new thread is created that executes the Check method. To update the application we copy everything in the work directory to the application directory, and then delete the work directory. Points of Interest In order to target the. All this code will do is call out to our ServiceProcess project. Check fetches the remote manifest, checks the SecurityToken for tampering, and compares the version of the remote manifest to that of the local one. Single XML file configuration. These are simply discarded, favoring programs that at least output something; and further guided and evolved until the output result is closer and closer to the desired solution. Microsoft cannot guarantee that these problems can be solved. Windows Installer deployment requires administrative permissions and allows only limited user installation; ClickOnce deployment enables non-administrative users to install and grants only those Code Access Security permissions necessary for the application. Files aren't checked for integrity i.

At some point the user may confirm that they want to install the available update, and the Updater downloads the app to a temporary location, then starts a process using that newly downloaded exe. If a newer version is available, download it as a ZIP. Local version is 2. Windows Installer deployment requires administrative permissions and allows only limited user installation; ClickOnce deployment enables non-administrative users to install and grants only those Code Access Security permissions necessary for the application.
