# this hook allows to allow or deny access to parts of a repo when | ||||
# taking incoming changesets. | ||||
# | ||||
# authorization is against local user name on system where hook is | ||||
# run, not committer of original changeset (since that is easy to | ||||
# spoof). | ||||
# | ||||
# acl hook is best to use if you use hgsh to set up restricted shells | ||||
# for authenticated users to only push to / pull from. not safe if | ||||
# user has interactive shell access, because they can disable hook. | ||||
# also not safe if remote users share one local account, because then | ||||
# no way to tell remote users apart. | ||||
# | ||||
# to use, configure acl extension in hgrc like this: | ||||
# | ||||
# [extensions] | ||||
# hgext.acl = | ||||
# | ||||
# [hooks] | ||||
# pretxnchangegroup.acl = python:hgext.acl.hook | ||||
# | ||||
# [acl] | ||||
# sources = serve # check if source of incoming changes in this list | ||||
# # ("serve" == ssh or http, "push", "pull", "bundle") | ||||
# | ||||
# allow and deny lists have subtree pattern (default syntax is glob) | ||||
# on left, user names on right. deny list checked before allow list. | ||||
# | ||||
# [acl.allow] | ||||
# # if acl.allow not present, all users allowed by default | ||||
# # empty acl.allow = no users allowed | ||||
# docs/** = doc_writer | ||||
# .hgtags = release_engineer | ||||
# | ||||
# [acl.deny] | ||||
# # if acl.deny not present, no users denied by default | ||||
# # empty acl.deny = all users allowed | ||||
# glob pattern = user4, user5 | ||||
# ** = user6 | ||||
