[libvirt] [PATCH 1/1] tests/virsh-checkpoint/snapshot: changing 'sed' out filtering

There is a chance that the current sed filtering used in these new tests might fail in some machines due to the repetition of the 'virsh #' prompt at the same line, together with valid output that shouldn't be filtered. This is output of virsh-snapshot test in my T480 dev box: ./virsh-snapshot --- exp 2019-07-31 18:42:31.107399428 -0300 +++ out.cooked 2019-07-31 18:42:31.108399437 -0300 @@ -1,8 +1,3 @@ - - -Domain snapshot s3 created from 's3.xml' -Domain snapshot s2 created from 's2.xml' -Name: s2 Domain: test Current: yes State: running There are 3 valid lines missing. This is the unfiltered output: === out === Welcome to lt-virsh, the virtualization interactive terminal. Type: 'help' for help with commands 'quit' to quit virsh # virsh # virsh # virsh # virsh # Domain snapshot s3 created from 's3.xml' virsh # Domain snapshot s2 created from 's2.xml' virsh # Name: s2 Domain: test Current: yes State: running Location: internal Parent: s3 Children: 0 Descendants: 0 Metadata: yes virsh # ============ We can see that the 3 lines being erased are being followed by the 'virsh #' prompt and the filtering is erasing those. A similar situation happens with virsh-checkpoint as well. This patch makes the 'sed' filtering less elegant and more crude than the current version, but more reliable to these outputs that may vary from each dev machine. We're also removing the blank lines in the expected output to make it less prone to errors as well.

I was going to send the commit msg as a reply to your query in the ML, then realized that I might as well propose a fix for it. tests/virsh-checkpoint | 6 +----- tests/virsh-snapshot | 6 ++---- 2 files changed, 3 insertions(+), 9 deletions(-) diff --git a/tests/virsh-checkpoint b/tests/virsh-checkpoint index 75bdc293be..a3cad74f74 100755 --- a/tests/virsh-checkpoint +++ b/tests/virsh-checkpoint @@ -152,20 +152,16 @@ $abs_top_builddir/tools/virsh -c test:///default >out 2>err <<EOF || fail=1 EOF cat <<\EOF > exp || fail=1 - - Domain checkpoint c3 created from 'c3.xml' Domain checkpoint c2 created from 'c2.xml' c2 - Name: c2 Domain: test Parent: c3 Children: 0 Descendants: 0 - EOF -sed '1,/^virsh #/d; /virsh #/d' < out > out.cooked || fail=1 +sed '1,/^virsh #/d; s/virsh #\s//g; /^$/d' < out > out.cooked || fail=1 compare exp out.cooked || fail=1 cat <<EOF > exp || fail=1 diff --git a/tests/virsh-snapshot b/tests/virsh-snapshot index 20ff966a51..874093ea3c 100755 --- a/tests/virsh-snapshot +++ b/tests/virsh-snapshot @@ -201,9 +201,8 @@ $abs_top_builddir/tools/virsh -c test:///default >out 2>err <<EOF || fail=1 snapshot-info test --current EOF -cat <<\EOF > exp || fail=1 - +cat <<\EOF > exp || fail=1 Domain snapshot s3 created from 's3.xml' Domain snapshot s2 created from 's2.xml' Name: s2 @@ -215,9 +214,8 @@ Parent: s3 Children: 0 Descendants: 0 Metadata: yes - EOF -sed '1,/^virsh #/d; /virsh #/d' < out > out.cooked || fail=1 +sed '1,/^virsh #/d; s/virsh #\s//g; /^$/d' < out > out.cooked || fail=1 compare exp out.cooked || fail=1 cat <<EOF > exp || fail=1 -- 2.21.0
