export: fixed silent output file overwriting
hg export -o outfile 1 2 3 4 had the same effect as hg -o outfile 4
This was caused by opening with 'w' instead of 'a'. This only occurs when
the filename pattern resulted in ambiguous patch filenames.
#!/bin/sh
hg init repo
cd repo
touch foo
hg add foo
for i in 0 1 2 3 4 5 6 7 8 9 10 11; do
echo "foo-$i" >> foo
hg ci -m "foo-$i" -d "0 0"
done
for out in "%nof%N" "%%%H" "%b-%R" "%h" "%r"; do
echo "# foo-$out.patch"
hg export -v -o "foo-$out.patch" 2:tip
done
echo "# exporting 4 changesets to a file"
hg export -o export_internal 1 2 3 4
grep HG export_internal | wc -l
echo "# exporting 4 changesets to a file"
hg export 1 2 3 4 | grep HG | wc -l
