Git::Bunch - Manage gitbunch directory (directory which contain git repos)
version 0.06
To check the status of bunch (will do a 'git status' for each git repo inside the bunch and report which repos are 'unclean', e.g. needs commit, has untracked files, etc):
% gitbunch check ~/repos
To synchronize bunch to another (will do a 'git pull' for each git repo, and do an rsync for everything else):
% gitbunch sync ~/repos /mnt/laptop/repos
To backup bunch (will only rsync .git/ for each git repo to destination, and rsync everything else in full):
% gitbunch backup ~/repos /media/flashdisk
A gitbunch or bunch directory is just a term I coined to refer to a directory which contains, well, a bunch of git repositories. It can also contain other stuffs like files and non-git repositories (but they must be dot-dirs). Example:
repos/ -> a gitbunch dir proj1/ -> a git repo proj2/ -> ditto perl-Git-Bunch/ -> ditto ... .foo/ -> a non-git dir README.txt -> file
A little bit of history: after git got popular, in 2008 I started using it for software projects, replacing Subversion and Bazaar. Soon, I moved everything to git: notes & writings, Emacs .org agenda files, configuration, even temporary downloads/browser-saved HTML files. Currently, except large media files, all my personal data resides in git repositories. I put them all in ~/repos (and add symlinks to various places for convenience). This setup makes it easy to sync to laptops, backup to disk, etc. Git::Bunch is the library/script I wrote to do this.
See also File::RsyBak, which I wrote to backup everything else.
None of the functions are exported by default, but they are exportable.
Backup bunch directory to another directory using rsync.
Simply uses rsync to copy bunch directory to another, except that for all git projects, only .git/ will be rsync-ed. This utilizes the fact that .git/ contains the whole project's data, the working copy can be checked out from .git/.
Will run check_bunch first and require all repos to be clean before running the backup, unless 'check' is turned off.
Note: Saving only .git/ subdirectory saves disk space, but will not save uncommited changes, untracked files, or .gitignore'd files. Make sure you have committed everything to git before doing backup. Also note that if you need to restore files, they will be checked out from the repository, and the original ctime/mtime information is not preserved. backup_bunch() does store this information for you by saving the output of 'ls -laR' command, but have *not* implemented routine to restore this data into restored files.
Returns a 3-element arrayref. STATUSCODE is 200 on success, or an error code between 3xx-5xx (just like in HTTP). ERRMSG is a string containing error message, RESULT is the actual result.
Arguments (* denotes required arguments):
*
source* => str
Directory to backup.
target* => str
Backup destination.
backup => bool (default 1)
1
Whether to do actual backup/rsync.
You can set backup=0 and index=1 to only run indexing, for example.
check => bool (default 1)
Whether to check bunch first before doing backup.
extra_rsync_opts => array
Pass extra options to rsync command.
Extra options to pass to rsync command. Note that the options will be shell quoted, , so you should pass it unquoted, e.g. ['--exclude', '/Program Files'].
index => bool (default 1)
Whether to do "ls -laR" after backup.
Check status of git repositories inside gitbunch directory.
Will perform a 'git status' for each git repositories inside the bunch and report which repositories are clean/unclean.
Will die if can't chdir into bunch or git repository.
Directory to check.
Synchronize bunch to another bunch.
For each git repository in the bunch, will perform a 'git pull' from the destination for each branch. If repository in destination doesn't exist, it will be rsync-ed first from source. When 'git pull' fails, will exit to let you fix the problem manually.
For all other non-git repos, will simply synchronize by one-way rsync.
Source bunch.
Destination bunch.
delete_branch => bool (default 0)
0
Whether to delete branches in dest repos not existing in source repos.
repos => array
Specific git repos to sync, if not specified all repos in the bunch will be processed.
