# @BLURB: generic fetching functions for the Bazaar VCS | ||
# @DESCRIPTION: | ||
# The bzr.eclass provides functions to fetch and unpack sources from | ||
# repositories of the Bazaar distributed version control system. | ||
# The eclass was originally derived from git.eclass. | ||
# | ||
# Note: Just set EBZR_REPO_URI to the URI of the branch and src_unpack() | ||
# of this eclass will export the branch to ${WORKDIR}/${P}. | ||

# @ECLASS-VARIABLE: EBZR_STORE_DIR | ||
# @DESCRIPTION: | ||
# The directory to store all fetched Bazaar live sources. | ||
: ${EBZR_STORE_DIR:=${PORTAGE_ACTUAL_DISTDIR:-${DISTDIR}}/bzr-src} | ||
|
||
# @ECLASS-VARIABLE: EBZR_UNPACK_DIR | ||
# @DESCRIPTION: | ||
# The working directory where the sources are copied to. | ||
: ${EBZR_UNPACK_DIR:=${WORKDIR}/${P}} | ||
|
||
# @ECLASS-VARIABLE: EBZR_INIT_REPO_CMD | ||
# @DESCRIPTION: | ||
# The Bazaar command to initialise a shared repository. | ||
: ${EBZR_INIT_REPO_CMD:="bzr init-repository --no-trees"} | ||
|
||
# @ECLASS-VARIABLE: EBZR_FETCH_CMD | ||
# @DESCRIPTION: | ||
# The Bazaar command to fetch the sources. | ||
: ${EBZR_FETCH_CMD:="bzr branch --no-tree"} | ||
|
||
# @ECLASS-VARIABLE: EBZR_UPDATE_CMD | ||
# @DESCRIPTION: | ||
# The Bazaar command to update the sources. | ||
: ${EBZR_UPDATE_CMD:="bzr pull --overwrite-tags"} | ||
|
||
# @ECLASS-VARIABLE: EBZR_EXPORT_CMD | ||
# @DESCRIPTION: | ||
# The Bazaar command to export a branch. | ||
: ${EBZR_EXPORT_CMD:="bzr export"} | ||
|
||
# @ECLASS-VARIABLE: EBZR_CHECKOUT_CMD | ||
# @DESCRIPTION: | ||
# The Bazaar command to checkout a branch. | ||
: ${EBZR_CHECKOUT_CMD:="bzr checkout --lightweight -q"} | ||
|
||
# @ECLASS-VARIABLE: EBZR_REVNO_CMD | ||
# @DESCRIPTION: | ||
# The Bazaar command to list a revision number of the branch. | ||
: ${EBZR_REVNO_CMD:="bzr revno"} | ||
|
||
# @ECLASS-VARIABLE: EBZR_OPTIONS | ||
# @DEFAULT_UNSET | ||
# @DESCRIPTION: | ||
# The options passed to the fetch and update commands. | ||
|
||
# @ECLASS-VARIABLE: EBZR_REPO_URI | ||
# @DEFAULT_UNSET | ||
# @REQUIRED | ||
# @DESCRIPTION: | ||
# The repository URI for the source package. | ||
# | ||
# Note: If the ebuild uses an sftp:// URI, then the eclass will depend | ||
# on dev-vcs/bzr[sftp]. | ||
|
||
# @ECLASS-VARIABLE: EBZR_INITIAL_URI | ||
# @DEFAULT_UNSET | ||
# @DESCRIPTION: | ||
# The URI used for initial branching of the source repository. If this | ||
# variable is set, the initial branch will be cloned from the location | ||
# specified, followed by a pull from ${EBZR_REPO_URI}. This is intended | ||
# for special cases, e.g. when download from the original repository is | ||
# slow, but a fast mirror exists but may be out of date. | ||
# | ||
# Normally, this variable needs not be set. | ||
|
||
# @ECLASS-VARIABLE: EBZR_PROJECT | ||
# @DESCRIPTION: | ||
# The project name of your ebuild. Normally, the branch will be stored | ||
# in the ${EBZR_STORE_DIR}/${EBZR_PROJECT} directory. | ||
# | ||
# If EBZR_BRANCH is set (see below), then a shared repository will be | ||
# created in that directory, and the branch will be located in | ||
# ${EBZR_STORE_DIR}/${EBZR_PROJECT}/${EBZR_BRANCH}. | ||
: ${EBZR_PROJECT:=${PN}} | ||
|
||
# @ECLASS-VARIABLE: EBZR_BRANCH | ||
# @DEFAULT_UNSET | ||
# @DESCRIPTION: | ||
# The directory where to store the branch within a shared repository, | ||
# relative to ${EBZR_STORE_DIR}/${EBZR_PROJECT}. | ||
# | ||
# This variable should be set if there are several live ebuilds for | ||
# different branches of the same upstream project. The branches can | ||
# then share the same repository in EBZR_PROJECT, which will save both | ||
# data traffic volume and disk space. | ||
# | ||
# If there is only a live ebuild for one single branch, EBZR_BRANCH | ||
# needs not be set. In this case, the branch will be stored in a | ||
# stand-alone repository directly in EBZR_PROJECT. | ||
|
||
# @ECLASS-VARIABLE: EBZR_REVISION | ||
# @DEFAULT_UNSET | ||
# @DESCRIPTION: | ||
# Revision to fetch, defaults to the latest | ||
# (see http://bazaar-vcs.org/BzrRevisionSpec or bzr help revisionspec). | ||
|
||
# @ECLASS-VARIABLE: EBZR_OFFLINE | ||
# @DESCRIPTION: | ||
# Set this variable to a non-empty value to disable automatic updating | ||
# of a bzr source tree. This is intended to be set outside the ebuild | ||
# by users. | ||
: ${EBZR_OFFLINE=${EVCS_OFFLINE}} | ||
|
||
# @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: EBZR_WORKDIR_CHECKOUT | ||
# @DEFAULT_UNSET | ||
# @DESCRIPTION: | ||
# If this variable is set to a non-empty value, EBZR_CHECKOUT_CMD will | ||
# be used instead of EBZR_EXPORT_CMD to copy the sources to WORKDIR. | ||
|
