This commit adds a shell library for writing raw loose objects into the object database. Normally this is done with hash-object, but the specific intent here is to allow broken objects that hash-object may not support. We'll convert several cases that use "hash-object --literally" to write objects with invalid types. That works currently, but dropping this dependency will allow us to remove that feature and simplify the object-writing code.

# Support routines for hand-crafting loose objects.

# Write a loose object into the odb at $1, with object type $2 and contents
|
|
# from stdin. Writes the oid to stdout. Example:
|
|
#
|
|
# oid=$(echo foo | loose_obj .git/objects blob)
|
|
#
|
|
loose_obj () {
|
|
cat >tmp_loose.content &&
|
|
size=$(wc -c <tmp_loose.content) &&
|
|
{
|
|
# Do not quote $size here; we want the shell
|
|
# to strip whitespace that "wc" adds on some platforms.
|
|
printf "%s %s\0" "$2" $size &&
|
|
