Git is changing my file's permissions when I push to server

This thread post offers a very good explanation:

This is by design. While the git data structure can technically store unix mode bits in its trees, it was found early on in git's history that respecting anything beyond a simple executable bit ended up being more cumbersome for git's normal use cases (i.e., people storing code or other shared files in a repository).

We could add in a config option to respect file modes, but it has generally been seen as not worthwhile. It solves only a part of the general metadata problem, as it omits owner and group names or ids, as well as extended metadata like ACLs.

If modes are important to you, the suggested fixes are one of:

1. Use a tool like "metastore" that can be called from git hooks, and will save and restore file permissions in a file that is tracked in the repository. Do note that when using such a tool there is a race condition in protecting files (i.e., git will create your file as 644, and then metastore will correct it to 600; in the meantime, somebody could read your file).

2. Depending on exactly what you're storing, it may make sense to keep your repository in another directory, protected by permissions, and then use a separate tool to deploy your files from the repository to their ultimate location (e.g., a Makefile or other install tool).

To extend the comment of @ThomasReggi that serves as a solution to the problem of changing permissions when deploying through git, I leave my implemented solution.You can add a command in the hooks / post-receive file (or whatever hook you are using)

Before the line with the git command --work-tree = (line that performs the deploy) Add some "echo" and the display of the current umask, the setting to the umask necessary to perform the deployment correctly and again the display of the current umask to confirm the change.(This way it can be seen (debug) when performing the deploy)

echo "Ref $ ref received. Deploying $ {BRANCH} branch to production ..."# SHOW current uMaskecho "Current uMASK:"umaskecho "Set uMASK to 0022"umask 0022echo "New uMASK seted to ..."umaskecho "end umask conf"# deployHUB_VERBOSE = 1git --work-tree = $ TARGET --git-dir = $ GIT_DIR checkout -f

This way the umask is only changed for the current session, without affecting the rest of the ssh connections. And also the files are deployed with the necessary permissions from their creation / modification, instead of using a command after the deployment to re-set the necessary permissions, causing your application to fail during the time it takes to apply the appropriate permissions.

If your permission problem affects your php application, it seems that this problem has to do with how you run php (DSO, suPHP, suEXEC) because each of them needs different permission settings to run correctly. If you migrated from server, or changed the php handler it is problem that you will experience this problem.
