From b5d18e873f08d2339ef8b08d3a0a9aafcf29b08f Mon Sep 17 00:00:00 2001 From: shiavm006 Date: Wed, 30 Jul 2025 23:02:40 +0530 Subject: [PATCH] Fix ancestor filter to support Docker-compatible substring matching - Remove redundant exact match checks in ancestor filter implementations - Add comprehensive test coverage for both prefix and non-prefix substring matching - Fix missing output verification in ID filter test - Improve test reliability with proper length checks and consistent flags - Remove unnecessary length check to ensure tests fail properly if image ID is too short - Add -q and --no-trunc flags for consistent test output format - Focus test on substring ID matching specifically (not image names) - Restore image name matching functionality for existing tests - Keep substring ID matching for Docker compatibility - Ensure both regex matching and substring ID matching work together The ancestor filter now supports both: 1. Image name matching (existing functionality) 2. Substring ID matching (new Docker compatibility feature) Fixes: #26623 Signed-off-by: shiavm006 --- pkg/domain/filters/containers.go | 18 ++++++++++---- test/e2e/ps_test.go | 40 +++++++++++++++++++++----------- 2 files changed, 41 insertions(+), 17 deletions(-) diff --git a/pkg/domain/filters/containers.go b/pkg/domain/filters/containers.go index ce1b849ed3..5d694e76d1 100644 --- a/pkg/domain/filters/containers.go +++ b/pkg/domain/filters/containers.go @@ -107,8 +107,13 @@ func GenerateContainerFilterFuncs(filter string, filterValues []string, r *libpo imageTag = tag } - if (rootfsImageID == filterValue) || - util.StringMatchRegexSlice(rootfsImageName, filterValues) || + // Check for substring match on image ID (Docker compatibility) + if strings.Contains(rootfsImageID, filterValue) { + return true + } + + // Check for regex match (advanced use cases) + if util.StringMatchRegexSlice(rootfsImageName, filterValues) || (util.StringMatchRegexSlice(imageNameWithoutTag, filterValues) && imageTag == "latest") { return true } @@ -363,8 +368,13 @@ func GenerateExternalContainerFilterFuncs(filter string, filterValues []string, imageTag = tag } - if (listContainer.ImageID == filterValue) || - util.StringMatchRegexSlice(listContainer.Image, filterValues) || + // Check for substring match on image ID (Docker compatibility) + if strings.Contains(listContainer.ImageID, filterValue) { + return true + } + + // Check for regex match (advanced use cases) + if util.StringMatchRegexSlice(listContainer.Image, filterValues) || (util.StringMatchRegexSlice(imageNameWithoutTag, filterValues) && imageTag == "latest") { return true } diff --git a/test/e2e/ps_test.go b/test/e2e/ps_test.go index d347c5b31e..16530cd5e5 100644 --- a/test/e2e/ps_test.go +++ b/test/e2e/ps_test.go @@ -334,25 +334,38 @@ var _ = Describe("Podman ps", func() { Expect(result.OutputToString()).To(Equal("")) }) + It("podman ps ancestor filter with substring matching (Docker compatibility)", func() { + // Create a container to test with + _, ec, cid := podmanTest.RunLsContainer("test1") + Expect(ec).To(Equal(0)) + + // Get the full image ID to test substring matching + inspect := podmanTest.PodmanExitCleanly("inspect", cid, "--format", "{{.Image}}") + fullImageID := inspect.OutputToString() + + // Test with prefix substring of image ID (Docker compatibility, new functionality) + imageIDPrefix := fullImageID[:12] + result := podmanTest.PodmanExitCleanly("ps", "-q", "--no-trunc", "-a", "--filter", "ancestor="+imageIDPrefix) + Expect(result.OutputToString()).To(Equal(cid)) + + // Test with non-prefix substring of image ID (Docker compatibility) + imageIDSubstr := fullImageID[4:16] + result = podmanTest.PodmanExitCleanly("ps", "-q", "--no-trunc", "-a", "--filter", "ancestor="+imageIDSubstr) + Expect(result.OutputToString()).To(Equal(cid)) + + // Test with non-existent substring (should not match) + result = podmanTest.PodmanExitCleanly("ps", "-q", "--no-trunc", "-a", "--filter", "ancestor=nonexistent") + Expect(result.OutputToString()).To(Equal("")) + }) + It("podman ps id filter flag", func() { _, ec, fullCid := podmanTest.RunLsContainer("") Expect(ec).To(Equal(0)) - result := podmanTest.Podman([]string{"ps", "-a", "--filter", fmt.Sprintf("id=%s", fullCid)}) + result := podmanTest.Podman([]string{"ps", "-aq", "--no-trunc", "--filter", fmt.Sprintf("id=%s", fullCid)}) result.WaitWithDefaultTimeout() Expect(result).Should(ExitCleanly()) - }) - - It("podman ps id filter flag", func() { - session := podmanTest.RunTopContainer("") - session.WaitWithDefaultTimeout() - Expect(session).Should(ExitCleanly()) - fullCid := session.OutputToString() - - result := podmanTest.Podman([]string{"ps", "-aq", "--no-trunc", "--filter", "status=running"}) - result.WaitWithDefaultTimeout() - Expect(result).Should(ExitCleanly()) - Expect(result.OutputToStringArray()[0]).To(Equal(fullCid)) + Expect(result.OutputToString()).To(Equal(fullCid)) }) It("podman ps multiple filters", func() { @@ -1033,4 +1046,5 @@ var _ = Describe("Podman ps", func() { Expect(output).To(HaveLen(1)) Expect(output).Should(ContainElement(ContainSubstring("late"))) }) + })
