If specified, the eclass will try -# to fetch from the local mirror instead of using the remote repository. -# -# The mirror needs to follow EGIT3_STORE_DIR structure. The directory -# created by eclass can be used for that purpose. -# -# Example: -# @CODE -# EGIT_MIRROR_URI="git://mirror.lan/" -# @CODE - -# @ECLASS-VARIABLE: EGIT_REPO_URI -# @REQUIRED -# @DESCRIPTION: -# URIs to the repository, e.g. https://foo. If multiple URIs are -# provided, the eclass will consider the remaining URIs as fallbacks -# to try if the first URI does not work. For supported URI syntaxes, -# read the manpage for git-clone(1). -# -# URIs should be using https:// whenever possible. http:// and git:// -# URIs are completely unsecured and their use (even if only as -# a fallback) renders the ebuild completely vulnerable to MITM attacks. -# -# It can be overridden via env using ${PN}_LIVE_REPO variable. -# -# Can be a whitespace-separated list or an array. -# -# Example: -# @CODE -# EGIT_REPO_URI="https://a/b.git https://c/d.git" -# @CODE - -# @ECLASS-VARIABLE: EVCS_OFFLINE -# @DEFAULT_UNSET -# @DESCRIPTION: -# If non-empty, this variable prevents any online operations. - -# @ECLASS-VARIABLE: EVCS_UMASK -# @DEFAULT_UNSET -# @DESCRIPTION: -# Set this variable to a custom umask. This is intended to be set by -# users. By setting this to something like 002, it can make life easier -# for people who do development as non-root (but are in the portage -# group), and then switch over to building with FEATURES=userpriv. -# Or vice-versa. Shouldn't be a security issue here as anyone who has -# portage group write access already can screw the system over in more -# creative ways. - -# @ECLASS-VARIABLE: EGIT_BRANCH -# @DEFAULT_UNSET -# @DESCRIPTION: -# The branch name to check out. If unset, the upstream default (HEAD) -# will be used. -# -# It can be overriden via env using ${PN}_LIVE_BRANCH variable. - -# @ECLASS-VARIABLE: EGIT_COMMIT -# @DEFAULT_UNSET -# @DESCRIPTION: -# The tag name or commit identifier to check out. If unset, newest -# commit from the branch will be used. Note that if set to a commit -# not on HEAD branch, EGIT_BRANCH needs to be set to a branch on which -# the commit is available. -# -# It can be overriden via env using ${PN}_LIVE_COMMIT variable. - -# @ECLASS-VARIABLE: EGIT_COMMIT_DATE -# @DEFAULT_UNSET -# @DESCRIPTION: -# Attempt to check out the repository state for the specified timestamp. -# The date should be in format understood by 'git rev-list'. The commits -# on EGIT_BRANCH will be considered. -# -# The eclass will select the last commit with commit date preceding -# the specified date. When merge commits are found, only first parents -# will be considered in order to avoid switching into external branches -# (assuming that merges are done correctly). In other words, each merge -# will be considered alike a single commit with date corresponding -# to the merge commit date. -# -# It can be overriden via env using ${PN}_LIVE_COMMIT_DATE variable. - -# @ECLASS-VARIABLE: EGIT_CHECKOUT_DIR -# @DESCRIPTION: -# The directory to check the git sources out to. -# -# EGIT_CHECKOUT_DIR=${WORKDIR}/${P} - -# @ECLASS-VARIABLE: EGIT_SUBMODULES -# @DEFAULT_UNSET -# @DESCRIPTION: -# An array of inclusive and exclusive wildcards on submodule names, -# stating which submodules are fetched and checked out.
