git-ts

git-ts begins life as a githooks(5) implementation for reporting and recording commits to a publictimestamp.org timestamp server. any un-garabage collected blobs will have their full paths recorded, making this tool suitable for usage of git as a version management and change control system.

currently it is designed to be fired via the post-commit hook.

experimenting instructions

• npm install git-ts
• use git-ts to get an audit block of the current commit.
• use git checkout <commit> to assert old trees, and run git-ts and compare the audit block hashes to verify.

installation instructions

git-ts's primary mode is serving as a post-commit script; the git-ts install command sets this up for you if you're anywhere in a local git repository.

first, find a working git-ts-publish set of parameters:

• use the -dry and -help commands to experiment!!! git-ts-publish will publish otherwise!!!
• inspect what data you want to publish first!
• note how git-ts-publish attemtps to auto-detects fields such as person, email, project and name.
  • disable specific fields such as --no-email
  • disable auto-detect entirely with --no-auto
• the u parameter will replace any %s found in the value with the commit object hash.

once you've arrived at a favorable set of parameters:

• from anywhere within a git heirarchy, issue a git-ts install command i
  • if there is no .git/hooks/post-commit, it will be generated
  • if there is a already a post-commit file, the .git/hooks/post-commit.git-ts-default will forcibly be written.
• the first parameter after install is a dedicated -u parameter. use "" if undesired.
• further parameters are passed verbatim

to use after install:

• just commit as one normally would.

implementation

it timestamps the object of commit, the blob of the commit, as well as the commit's fully pathed tree with filesizes.

for example:

0471cf8825969c8fc8f428afd3e6c23e4065786f
tree 913d9b38ed1a06236c042824c4cfd80c30e19490
parent 5179451d189a9c4cf42461b143e54c38f92eefe8
author rektide <[email protected]> 1315301027 -0400
committer rektide <[email protected]> 1315301027 -0400

Add second parameter to git-ts install to add url into post-commit script. %s is substituted for the commit blob.
