Using gmail api via service account credential

For some reason, I need to grab a mail attachment to store its content into database everyday.

So obviously I can’t use the normal OAuth approach because no one can authorized this action every day, that leaves service account to get this thing done.

First, I need a service account, follow the instructions of Creating a service account section

And as a service account to access gmail, I have to impersonate as some real user to access thier mails, I could only do that in a Google Apps for Work domain.

To do so, I checked the next section of document, Delegating domain-wide authority to the service account.

But I can’t find the client id on the web console anywhere, I do find one client_id field in the .json key file though, which the Manage API client access panel doesn’t accept it at all.

Redmine repositories from gitolite

Only two steps:

  1. Let www-data have read access of /path-to-gitolite-root/repositories

    cd /path-to-gitolite-root

    # let all repos readable for all users, but not writable except owner
    chmod a+rX,go-w -R repositories

    # keep gitolite-admin remains only readable/writable by owner
    chmod go-rwX -R repositories/gitolite-admin.git

  2. Keep it that way when gitolite add any new things
