discovery-helper: move repository creation in a function
This makes it easier to update this duplicated code.
(we do a small output fix as we go)

#!/bin/bash # # produces two repositories with different common and missing subsets # # $ discovery-helper.sh REPO NBHEADS DEPT # # The Goal is to produce two repositories with some common part and some # exclusive part on each side. Provide a source repository REPO, it will # produce two repositories REPO-left and REPO-right. # # Each repository will be missing some revisions exclusive to NBHEADS of the # repo topological heads. These heads and revisions exclusive to them (up to # DEPTH depth) are stripped. # # The "left" repository will use the NBHEADS first heads (sorted by # description). The "right" use the last NBHEADS one. # # To find out how many topological heads a repo has, use: # # $ hg heads -t -T '{rev}\n' | wc -l # # Example: # # The `pypy-2018-09-01` repository has 192 heads. To produce two repositories # with 92 common heads and ~50 exclusive heads on each side. # # $ ./discovery-helper.sh pypy-2018-08-01 50 10 set -euo pipefail printusage () { echo "usage: `basename $0` REPO NBHEADS DEPTH [left|right]" >&2 } if [ $# -lt 3 ]; then printusage exit 64 fi repo="$1" shift nbheads="$1" shift depth="$1" shift doleft=1 doright=1 if [ $# -gt 1 ]; then printusage exit 64 elif [ $# -eq 1 ]; then if [ "$1" == "left" ]; then doleft=1 doright=0 elif [ "$1" == "right" ]; then doleft=0 doright=1 else printusage exit 64 fi fi leftrepo="${repo}-${nbheads}h-${depth}d-left" rightrepo="${repo}-${nbheads}h-${depth}d-right" left="first(sort(heads(all()), 'desc'), $nbheads)" right="last(sort(heads(all()), 'desc'), $nbheads)" leftsubset="ancestors($left, $depth) and only($left, heads(all() - $left))" rightsubset="ancestors($right, $depth) and only($right, heads(all() - $right))" echo '### creating left/right repositories with missing changesets:' if [ $doleft -eq 1 ]; then echo '# left revset:' '"'${leftsubset}'"' fi if [ $doright -eq 1 ]; then echo '# right revset:' '"'${rightsubset}'"' fi buildone() { side=$1 dest=$2 revset=$3 echo "### building $side repository: $dest" echo '# cloning' hg clone --noupdate "${repo}" "${dest}" echo '# stripping' '"'${revset}'"' hg -R "${dest}" --config extensions.strip= strip --rev "$revset" --no-backup } if [ $doleft -eq 1 ]; then buildone left $leftrepo $leftsubset fi if [ $doright -eq 1 ]; then buildone right $rightrepo $rightsubset fi
