#git-tools A collection of git tools.

##git-gdrive git-gdrive allows to use Google Drive as a way to exchange patchsets.
In essence it's git format-patch / git am but based on Google Drive.
This project has been packaged and moved to github.com/primiano/git-gdrive

pip install --user git-gdrive

• git gdrive push is the equivalent of git format-patch + upload to gdrive;
• git gdrive pull is the equivalent of download from gdrive + git am

##git-gradual-push git-gradual-push, as the name suggests, allows to push large revision ranges in chunks (read: generating multiple push operations). This is to deal with pushes of really large repos which cannot get digested by the Git server in a single push. It works by figuring out the total number of revisions, splitting it in chunks of arbitrary size (4th arg), and issuing individual git push commands with the intermediate revisions calculated.

Example

$ git-gradual-push origin HEAD refs/heads/master 10000
Remember to: git config credential.helper 'cache --timeout=3600' to avoid surprises
Reading rev-list for branch  HEAD
Got 168278 revisions. Uploading in 17 chunks

Push [1/17] (158278-th) 8f1021083ad8 -> refs/hidden/tmpupload
+ 4eb5bbc...8f10210 8f1021083ad8a887413ca373a3fa0dfa74e45f53 -> refs/hidden/tmpupload

##git-inspect-packs git-inspect-packs is a low level tool to inspect git pack files.

Given a set of pack files (the tools operates on a directory, loading all the packs in it), it can report:

• The list of commits present in the pack files.
• The subset of root commits (i.e. commits which have no parents in the pack files being inspected).
• The cardinality and size of the blobs referenced by each commit.
• The list of trees present in the pack files.
• The subset of orphan trees (trees not referenced by any commit in the pack files being inspected)
• The list of blobs.
• The list of orphan blobs (blobs not referenced by any tree in the pack files being inspected).

It can be used to debug and inspect the content provided by a given set of pack files. Conversely to most git operations it is designed to deal with incomplete packs (i.e. references to missing objects). The use case driving the development of this script has been debugging anomalous packs being downloaded and exploding their content (and doing some graph math on it).

Example

$ ls
pack-d0c10508154396e8ae03a18a47f6fd0da97562fa.idx
pack-d0c10508154396e8ae03a18a47f6fd0da97562fa.pack
