# Git imposes the following rules on how references are named:
|
|
#
|
|
# 1. They can include slash / for hierarchical (directory) grouping, but no slash-separated component can begin with a dot . or end with the sequence .lock.
|
|
# 2. They must contain at least one /. This enforces the presence of a category like heads/, tags/ etc. but the actual names are not restricted. If the --allow-onelevel option is used, this rule is waived.
|
|
# 3. They cannot have two consecutive dots .. anywhere.
|
|
# 4. They cannot have ASCII control characters (i.e. bytes whose values are lower than \040, or \177 DEL), space, tilde ~, caret ^, or colon : anywhere.
|
|
# 5. They cannot have question-mark ?, asterisk *, or open bracket [ anywhere. See the --refspec-pattern option below for an exception to this rule.
|
|
# 6. They cannot begin or end with a slash / or contain multiple consecutive slashes (see the --normalize option below for an exception to this rule)
|
|
# 7. They cannot end with a dot ..
|
|
# 8. They cannot contain a sequence @{.
|
|
# 9. They cannot be the single character @.
|
|
# 10. They cannot contain a \.
