Installation

Symlink the script to a location visible by PATH. I have mine set to ~/bin.

An optional global variable GIT_CACHED_DIR can be set. This is where the cached objects are stored. The default is shown below.

export PATH=$HOME/bin:$PATH
export GIT_CACHED_DIR=$HOME/.gitobjectstore

Usage

gitc accepts all git commands. For the ones it does not know of, it will simply pass-through to git.

When cloning, use the cclone (two c's as in cached clone).

gitc cclone --branch 8.x git://git.drupal.org/project/drupal.git

If at anytime you need to remove all reference to the cache (runs git repack -a -d -l and removes pointer in the alternates file.:

gitc cache-detach

It can be added back at any time (runs git gc garbage collection to remove local objects):

gitc cache-attach

To repair it (it simply detaches and reattaches):

gitc cache-repair

If you need to run git commands on the cache store itself, use the cache sub-command:

gitc cache remote

When cloning, attaching or repairing, you can pass in a --store-group option to tell it to use a separate object store. It defautls to default.

gitc cclone --store-group foobar --branch 8.x git://git.drupal.org/project/drupal.git

The above command will point the object store to $HOME/.gitobjectstore/foobar. (defaults to $HOME/.gitobjectstore/default)

Notes

  • The cached clone is set with --reference pointing to the object storage. See the man page for git-clone.
  • If you move the clone to another machine it may invalidate the path pointing to the object store. Changing GIT_CACHE_DIR will do the same. Simply call gitc cache-repair in your working directory to fix it.
  • This is the first bash script I’ve created. Consider this a fair warning. Tested on Mac OSX Lion.
  • I personally don't use this for critical work. I'm using this to reduce the bandwidth and disk space on multiple versions of checked out repos that are mostly read only. It does work fine from what I've tested.
  • This new development version is incompatible with the master branch.
Something went wrong with that request. Please try again.
