NAME

Git::Bunch - Manage gitbunch directory (directory which contain git repos)

VERSION

This document describes version 0.58 of Git::Bunch (from Perl distribution Git-Bunch), released on 2016-11-29.

SYNOPSIS

See the included gitbunch script.

DESCRIPTION

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
   ...
   .videos/        -> a non-git dir
   README.txt      -> file

If you organize your data as a bunch, you can easily check the status of your repositories and synchronize your data between two locations, e.g. your computer's harddisk and an external/USB harddisk.

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 repositories: notes & writings, Emacs .org agenda files, configuration, even temporary downloads/browser-saved HTML files. I put the repositories inside $HOME/repos and add symlinks to various places for conveniences. Thus, the $HOME/repos became the first bunch directory.

*) everything except large media files (e.g. recorded videos) which I put in dot-dirs inside the bunch.

See also rsybak, which I wrote to backup everything else.

FUNCTIONS

check_bunch(%args) -> [status, msg, result, meta]

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.

This function is not exported by default, but exportable.

This function supports dry-run operation.

Arguments ('*' denotes required arguments):

  • exclude_files => bool

    Exclude files from processing.

    This only applies to sync_bunch operations. Operations like check_bunch and exec_bunch already ignore these and only operate on git repos.

  • exclude_non_git_dirs => bool

    Exclude non-git dirs from processing.

    This only applies to and sync_bunch operations. Operations like check_bunch and exec_bunch already ignore these and only operate on git repos.

  • exclude_repos => array[str]

    Exclude some repos from processing.

  • exclude_repos_pat => str

    Specify regex pattern of repos to exclude.

  • include_repos => array[str]

    Specific git repos to sync, if not specified all repos in the bunch will be processed.

  • include_repos_pat => str

    Specify regex pattern of repos to include.

  • min_repo_access_time => date

    Limit to repos that are accessed (mtime, committed, status-ed, pushed) recently.

    This can significantly reduce the time to process the bunch if you are only interested in recent repos (which is most of the time unless you are doing a full check/sync).

  • repo => str

    Only process a single repo.

  • source* => str

    Directory to check.

Special arguments:

  • -dry_run => bool

    Pass -dry_run=>1 to enable simulation mode.

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

exec_bunch(%args) -> [status, msg, result, meta]

Execute a command for each repo in the bunch.

For each git repository in the bunch, will chdir to it and execute specified command.

Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

sync_bunch(%args) -> [status, msg, result, meta]

Synchronize bunch to another bunch.

For each git repository in the bunch, will perform a 'git pull/push' 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-repo file/directory, will simply synchronize by one-way rsync. But, for added safety, will first check the newest mtime (mtime of the newest file or subdirectory) between source and target is checked first. If target contains the newer newest mtime, rsync-ing for that non-repo file/dir will be aborted. Note: you can use --skip-mtime-check option to skip this check.

This function is not exported by default, but exportable.

This function supports dry-run operation.

Arguments ('*' denotes required arguments):

  • backup => bool

    Whether doing backup to target.

    This setting lets you express that you want to perform synchronizing to a backup target, and that you do not do work on the target. Thus, you do not care about uncommitted or untracked files/dirs in the target repos (might happen if you also do periodic copying of repos to backup using cp/rsync). When this setting is turned on, the function will first do a git clean -f -d (to delete untracked files/dirs) and then git checkout . (to discard all uncommitted changes). This setting will also implicitly turn on create_bare setting (unless that setting has been explicitly enabled/disabled).

  • create_bare_target => bool

    Whether to create bare git repo when target does not exist.

    When target repo does not exist, gitbunch can either copy the source repo using rsync (the default, if this setting is undefined), or it can create target repo with git init --bare (if this setting is set to 1), or it can create target repo with git init (if this setting is set to 0).

    Bare git repositories contain only contents of the .git folder inside the directory and no working copies of your source files.

    Creating bare repos are apt for backup purposes since they are more space-efficient.

    Non-repos will still be copied/rsync-ed.

  • delete_branch => bool (default: 0)

    Whether to delete branches in dest repos not existing in source repos.

  • exclude_files => bool

    Exclude files from processing.

    This only applies to sync_bunch operations. Operations like check_bunch and exec_bunch already ignore these and only operate on git repos.

  • exclude_non_git_dirs => bool

    Exclude non-git dirs from processing.

    This only applies to and sync_bunch operations. Operations like check_bunch and exec_bunch already ignore these and only operate on git repos.

  • exclude_repos => array[str]

    Exclude some repos from processing.

  • exclude_repos_pat => str

    Specify regex pattern of repos to exclude.

  • include_repos => array[str]

    Specific git repos to sync, if not specified all repos in the bunch will be processed.

  • include_repos_pat => str

    Specify regex pattern of repos to include.

  • min_repo_access_time => date

    Limit to repos that are accessed (mtime, committed, status-ed, pushed) recently.

    This can significantly reduce the time to process the bunch if you are only interested in recent repos (which is most of the time unless you are doing a full check/sync).

  • repo => str

    Only process a single repo.

  • rsync_del => bool

    Whether to use --del rsync option.

    When rsync-ing non-repos, by default --del option is not used for more safety because rsync is a one-way action. To add rsync --del option, enable this

  • rsync_opt_maintain_ownership => bool (default: 0)

    Whether or not, when rsync-ing from source, we use -a (= -rlptgoD) or -rlptD (-a minus -go).

    Sometimes using -a results in failure to preserve permission modes on sshfs-mounted filesystem, while -rlptD succeeds, so by default we don't maintain ownership. If you need to maintain ownership (e.g. you run as root and the repos are not owned by root), turn this option on.

  • skip_mtime_check => bool

    Whether or not, when rsync-ing non-repos, we check mtime first.

    By default when we rsync a non-repo file/dir from source to target and both exist, to protect wrong direction of sync-ing we find the newest mtime in source or dir (if dir, then the dir is recursively traversed to find the file/subdir with the newest mtime). If target contains the newer mtime, the sync for that non-repo file/dir is aborted. If you want to force the rsync anyway, use this option.

  • source* => str

    Directory to check.

  • target* => str

    Destination bunch.

Special arguments:

  • -dry_run => bool

    Pass -dry_run=>1 to enable simulation mode.

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

SEE ALSO

rsybak.

http://joeyh.name/code/mr/. You probably want to use this instead. mr supports other control version software aside from git, doesn't restrict you to put all your repos in one directory, supports more operations, and has been developed since 2007. Had I known about mr, I probably wouldn't have started gitbunch. On the other hand, gitbunch is simpler (I think), doesn't require any config file, and can copy/sync files/directories not under source control. I mainly use gitbunch to quickly: 1) check whether there are any of my repositories which have uncommitted changes; 2) synchronize (pull/push) to other locations. I put all my data in one big gitbunch directory; I find it simpler. gitbunch works for me and I use it daily.
