Re: post-receive for web deployment

[Stephen Major <smajor@gmail.com>]

Hello,

I am having some difficulty understanding what I am doing wrong when
working with git to deploy a website through the use of a post-receive
hook on the remote.

Here is the script:

#!/bin/sh

staging_path="/home/user/domains/domain.com/public_html/staging"
live_path="/home/user/domains/domain.com/public_html/live"


while read oldrev newrev ref
do

    branch=$(echo $ref | cut -d/ -f3)

    # ***
    # update the live site
    #
    if [[ "master" == "$branch" ]]; then

        export GIT_WORK_TREE=$live_path
        git checkout -f $branch

        echo "Release has been pushed to production"

    # ***
    # we update the staging server with the latest push
    #
    elif [[ "develop" == "$branch" ]]; then

        echo "Resetting staging tree"
        export GIT_WORK_TREE=$staging_path

        git checkout -f $branch

        echo "Develop has been pushed to staging"

    fi

done



This is what we have done:

git checkout develop
touch 1 2 3 4 5 6
git add .
git commit -am "added some files"
git push origin develop

checking the remote server now all files are found in:
/home/user/domains/domain.com/public_html/staging

git checkout master
git merge develop
git push origin master

checking the remote server now all files are found in:
/home/user/domains/domain.com/public_html/live

git checkout develop
git rm 4 5 6
git commit -am "removed some files"
git push origin develop

checking the remote server now files 4 5 6 have been removed from:
/home/user/domains/domain.com/public_html/staging

git checkout master
git merge develop
git push origin master

checking the remote server files 4 5 6 are still found in:
/home/user/domains/domain.com/public_html/live

Why is this happening? checking the local repo for master shows the
files are removed there... pulling the latest from origin:master shows
the files have been removed... but why were they not removed from the
working tree like they were on the staging working tree?


well I think it has something to do with later commits and therefor
the working tree of the live server could quickly become out of sync
with the development tree

a quick test, lets checkout master again and perform the removes
directly on it then push it back:

git checkout master
git rm 1 2 3
git commit -am "removed 1 2 3"
git push origin master

checking the remote server now files 1 2 3 have been removed from:
/home/user/domains/domain.com/public_html/live


Okay weird so they remove when the commit happens directly on that
branch and is pushed to the remote but they dont get removed if the
removal happened on a different branch and is merged in then pushed to
the remote....

anyone have an explanation or a workaround?
