# This script makes snapshots from a git repository. The input is
|
|
# the number for a snapshot and the path to a temporary directory.
|
|
# for example:
|
|
#
|
|
# sh scripts/MAKE_SNAPSHOT.sh 20080428 ~/tmp
|
|
#
|
|
# The above assumes that there is a tag "s20080428" at the point
|
|
# to be snapshot. (The tag has the "s", but the argument to this
|
|
# script does not have the "s"). This script extracts based on the
|
|
# tag, uses the temporary directory to stage intermediate results,
|
|
# and finally creates a file called verilog-20080428.tar.gz that
|
|
# contains the snapshot ready to go.
|
|
#
|
|
# The complete steps to make a snapshot YYYYMMDD generally are:
|
|
#
|
|
# edit the verilog.spec to set the rev_date to YYYYMMDD
|
|
#
|
|
# git tag -a sYYYYMMDD
|
|
# (Make the tag in the local git repository.)
|
|
#
|
|
# sh scripts/MAKE_SNAPSHOT.sh YYYYMMDD ~/tmp
|
|
# (Make the snapshot bundle verilog-YYYYMMDD.tar.gz)
|
|
#
|
|
# git push --tags
|
|
# (Publish the tag to the repository.)
|
|
