Subject: [PATCH v3 05/17] CLI/git: Add an 'init' command
Date: Sat, 4 Jun 2022 14:23:01 -0300 [thread overview]
Message-ID: <20220604172313.1149879-6-david@tethera.net> (raw)
In-Reply-To: <20220604172313.1149879-1-david@tethera.net>
From: "W. Trevor King" <wking@tremily.us>
For folks that want to start versioning a new tag-space, instead of
cloning one that someone else has already started.
The empty-blob hash-object call avoids errors like:
$ nmbug commit
error: invalid object 100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 for
'tags/...'
fatal: git-write-tree: error building trees
'git HASH(0x9ef3eb8) write-tree' exited with nonzero value
David Bremner suggested [1]:
$ git hash-object -w /dev/null
instead of my Python version of:
$ git hash-object -w --stdin <&-
but I expect that closing stdin is more portable than the /dev/null
path (which doesn't exist on Windows, for example).
The --bare init and use of NMBGIT as the work tree (what could go
wrong with an empty commit?) are suggestions from Michal Sojka [2].
