Another way to dump amd load path of SVN repo: creating empty repo, commiting needed commits and update props

commits-migrate.sh

#!/bin/bash

# set empty repo with enabled pre-revprop-change hook

# set first last revisions to dump and migrate
first_rev='1'
last_rev='15'
# range of revisions of old repo to migrate
revs="$(svn log -q -r$first_rev:$last_rev | grep -oE '^r[0-9]+' | tr -d 'r' | sort -n)"

# working copy of empty repo where old revisions will be moved
empty_repo='../empty_repo/'

new_rev=1
for rev in $revs; do
	svn up -r$rev --force
	
	commit_msg=$(svn log -r$rev | sed '4!d')
	commit_author=$(svn log -r$rev  | sed '2 !d' | cut -d'|' -f2)
	commit_date=$(date -u +"%Y-%m-%dT%H:%M:%S.000000Z" -d "$(LANG=C svn info | grep 'Date' | cut -d' ' -f4-8)")
	echo "* Commit info to migrate: $commit_author | $date | $commit_msg"

	rsync -av --exclude=".svn/" ./ "$empty_repo"
	pushd "$empty_repo"
	svn add . --force
	svn commit -m "$commit_msg"
	svn propset --revprop -r$new_rev svn:author $commit_author
	svn propset --revprop -r$new_rev svn:date $commit_date
	popd
	let new_rev+=1
done
