# SelfUpdate

The goal here is learning about auto updating applications

# Developer

Name:  Anthony

Email: Anthony.Tracy@colorado.edu

# Version Definition

Major - For larger overhauls, things like Changing workflows, etc.

Minor - For adding features, things like new buttons, etc.

Patch - For fixing bugs, logic, etc.

# How to compile

So far it has been tested with Windows 10 and Ubuntu 16.

Windows:

Install Visual Studio compiler (this has been tested with VS14)

cd (path/to/superDirectory)/build/

cmake ..

cmake --build

cd /build/Debug/

./SelfUpdate.exe

Windows:

cd (path/to/superDirectory)/build/

cmake ..

make -j4

cd /build/

./SelfUpdate.exe

# The idea (First stages)

Start with something simple: An app that prints "Hello World: Your Current Version is: Major.Minor.SubMinor

1. On Startup:

   1.1 Start Updater

       - Checks if there is a newer version in a local subdirectory "versions"

          False - Cleanup curr directory to remove older version and check that old version did shut down correctly

          True - Start newest version, verify it is running, kill self

       - Updater should be a on it's own thread and checking for updates at some time interval from github repo (since it's free, 

         in production it would be bettter to have a CI system like teamcity pushing artifacts with recent builds which this would instead check)

       - Let updater using something like libcurl (since it can be compiled from source for linux, windows, etc)

       -  

       

2. Open some type of UI

   2.1 Print: Hello World! Your current software version is: Major.Minor.Subminor

       - While the app is running the background thread will be running Updater which query the webpage every N hours (N is undecided atm)

       - If a newer version occurs, ask user if they would like to update 

         - If Yes - Have the app call updater.update() with just downloads the newer version into the version subdirectory, starts it,

           and ends itself

         - If no - let user keep doing what they are doing, the updater will ask again later (like windows) 

           -- NOTE: This could get annoying, perhaps have a flag that indicates user declined update. Just meaning when they close the app it will update on next startup

# The next Idea (Second stage) - I don't want to think about this fully till stage one has UTs and is working
