Ref-updated gerrit script to send emails via the mail command when commits are pushed directly to gerrit. Install into the gerrit/hooks directory and make sure it is executable. You may want to change the "gitblit.rams" url to point to your own source code viewing website (such as a gitblit server). This has been tested on Gerrit 2.5

Hi, have you wrote ref-update hook for gerrit in windows?

I have a ref-update.bat hook, and in ref-update.bak I call/run the python script, then it disappears an error when I push changes to gerrit.
the python script can be run, because I can get the log from the python script.

If I don't call/run python script or others scripts, the ref-update.bak works. why?
Tips: the gerrit version is 2.13
Do you have any idea? thanks.
