merge: store cases when a file is absent post merge in commitinfo
Some merges can result in file being absent form working directory. This can be
one of file was kept deleted or file was removed by merge code.
User might revert the file back before committing. In such cases we will like to
have better handling and create new filenodes.
We store this info in mergestate as commitinfo so that we can use it while
committing to create new filenode if required.

#!/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: $dest" if [ -e "$dest" ]; then echo "destination repo already exists: $dest" >&2 exit 1 fi echo '# cloning' if ! cp --recursive --reflink=always ${repo} ${dest}; then hg clone --noupdate "${repo}" "${dest}" fi echo '# stripping' '"'${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
