FTP - transfer checksum

It will be great if the deployment will do checksum against previous transfer (same file) before begin the FTP file transfer. If same, then it will skip the transfer. With this, it can speed up the deployment, and save your server bandwidth (network+IO+processing power).

Of course this can be option that user can enable to "speed-up" the deployment or disable it for always replace.

    Maybe you can use WinSCP instead of built-in FTP deployment. Looks like it can be installed with Chocolatey: https://chocolatey.org/packages/winscp

    It can be installed with the following command added to "Install" section:

    choco install winscp

    Thanks for the swift response,

    I just added it settings/environment -> Install script section.

    Do I need to do anything else?

    The idea is to use your own deployment script instead of built-in AppVeyor provider. You should replace built-in FTP deployment method with your own command calling winscp command line. Sorry, I don't have a ready example, but I think it could be easily googled.

    Btw, why wouldn't just replace FTP with WebDeploy (if you control target server of course)? Web Deploy is way more effective in managing partial updates.

    The problem is the hosting that I using don't support WebDeploy :(, it only support FTP And for my case it will take more than one hour to complete transfer.

    Always thanks for the swift response, where can I get the list of "variable" and how do I know where the "artifcat" path saved and located? before I use command to extract it, upload it.

    There is $artifacts hashtable in PowerShell context: http://www.appveyor.com/docs/packaging-artifacts#getting-informatio...

    You can take the first artifact's path as the following:

    - ps: '$env:ApplicationPath=$artifacts.values[0].path'
    - your command with %ApplicationPath%
