# Usage: cd /usr/src/contrib/jemalloc
|
|
# ./FREEBSD-upgrade <command> [args]
|
|
#
|
|
# At least the following ports are required when importing jemalloc:
|
|
# - devel/autoconf
|
|
# - devel/git
|
|
# - devel/gmake
|
|
# - textproc/docbook-xsl
|
|
# - textproc/libxslt
|
|
#
|
|
# The normal workflow for importing a new release is:
|
|
#
|
|
# cd /usr/src/contrib/jemalloc
|
|
#
|
|
# Merge local changes that were made since the previous import:
|
|
#
|
|
# ./FREEBSD-upgrade merge-changes
|
|
# ./FREEBSD-upgrade rediff
|
|
#
|
|
# Extract latest jemalloc release.
|
|
#
|
|
# ./FREEBSD-upgrade extract
|
|
#
|
|
# Fix patch conflicts as necessary, then regenerate diffs to update line
|
|
# offsets:
|
|
#
|
|
# ./FREEBSD-upgrade rediff
|
|
# ./FREEBSD-upgrade extract
|
|
#
|
|
# Do multiple buildworld/installworld rounds. If problems arise and patches
|
|
# are needed, edit the code in ${work} as necessary, then:
|
|
#
|
|
# ./FREEBSD-upgrade rediff
|
|
# ./FREEBSD-upgrade extract
|
|
#
|
|
# The rediff/extract order is important because rediff saves the local
|
|
# changes, then extract blows away the work tree and re-creates it with the
|
|
# diffs applied.
|
|
#
|
|
# Finally, to clean up:
|
|
#
|
|
# ./FREEBSD-upgrade clean
|
|
|
