virstoragetest was failing on RHEL 5, but with no good error message: TEST: virstoragetest 0 FAIL It turns out that qemu-img was so old, that it lacked support for -o backing_file. It didn't help that the test was also using qemu-img from PATH, even after first probing for kvm-img. * tests/virstoragetest.c (testPrepImages): Consistently use discovered binary. Skip instead of fail if qemu-img fails during setup. --- Pushing under the build-breaker rule; this gets RHEL 5 from 5 test failures down to 4. tests/virstoragetest.c | 36 +++++++++++++++++++----------------- 1 file changed, 19 insertions(+), 17 deletions(-) diff --git a/tests/virstoragetest.c b/tests/virstoragetest.c index 6ca7b9a..d495e6a 100644 --- a/tests/virstoragetest.c +++ b/tests/virstoragetest.c @@ -89,10 +89,8 @@ testPrepImages(void) qemuimg = virFindFileInPath("kvm-img"); if (!qemuimg) qemuimg = virFindFileInPath("qemu-img"); - if (!qemuimg) { - fputs("qemu-img missing or too old; skipping this test\n", stderr); - return EXIT_AM_SKIP; - } + if (!qemuimg) + goto skip; if (virAsprintf(&absraw, "%s/raw", datadir) < 0 || virAsprintf(&absqcow2, "%s/qcow2", datadir) < 0 || @@ -116,8 +114,10 @@ testPrepImages(void) /* I'm lazy enough to use a shell one-liner instead of open/write/close */ virCommandFree(cmd); cmd = virCommandNewArgList("sh", "-c", "printf %1024d 0 > raw", NULL); - if (virCommandRun(cmd, NULL) < 0) + if (virCommandRun(cmd, NULL) < 0) { + fprintf(stderr, "unable to create raw file\n"); goto cleanup; + } if (!(canonraw = canonicalize_file_name(absraw))) { virReportOOMError(); goto cleanup; @@ -126,20 +126,17 @@ testPrepImages(void) /* Create a qcow2 wrapping relative raw; later on, we modify its * metadata to test other configurations */ virCommandFree(cmd); - cmd = virCommandNewArgList("qemu-img", "create", "-f", "qcow2", + cmd = virCommandNewArgList(qemuimg, "create", "-f", "qcow2", "-obacking_file=raw,backing_fmt=raw", "qcow2", NULL); if (virCommandRun(cmd, NULL) < 0) - goto cleanup; + goto skip; /* Make sure our later uses of 'qemu-img rebase' will work */ virCommandFree(cmd); - cmd = virCommandNewArgList("qemu-img", "rebase", "-u", "-f", "qcow2", + cmd = virCommandNewArgList(qemuimg, "rebase", "-u", "-f", "qcow2", "-F", "raw", "-b", "raw", "qcow2", NULL); - if (virCommandRun(cmd, NULL) < 0) { - fputs("qemu-img is too old; skipping this test\n", stderr); - ret = EXIT_AM_SKIP; - goto cleanup; - } + if (virCommandRun(cmd, NULL) < 0) + goto skip; if (!(canonqcow2 = canonicalize_file_name(absqcow2))) { virReportOOMError(); goto cleanup; @@ -148,21 +145,21 @@ testPrepImages(void) /* Create a second qcow2 wrapping the first, to be sure that we * can correctly avoid insecure probing. */ virCommandFree(cmd); - cmd = virCommandNewArgList("qemu-img", "create", "-f", "qcow2", NULL); + cmd = virCommandNewArgList(qemuimg, "create", "-f", "qcow2", NULL); virCommandAddArgFormat(cmd, "-obacking_file=%s,backing_fmt=qcow2", absqcow2); virCommandAddArg(cmd, "wrap"); if (virCommandRun(cmd, NULL) < 0) - goto cleanup; + goto skip; /* Create a qed file. */ virCommandFree(cmd); - cmd = virCommandNewArgList("qemu-img", "create", "-f", "qed", NULL); + cmd = virCommandNewArgList(qemuimg, "create", "-f", "qed", NULL); virCommandAddArgFormat(cmd, "-obacking_file=%s,backing_fmt=raw", absraw); virCommandAddArg(cmd, "qed"); if (virCommandRun(cmd, NULL) < 0) - goto cleanup; + goto skip; /* Create some symlinks in a sub-directory. */ if (symlink("../qcow2", datadir "/sub/link1") < 0 || @@ -177,6 +174,11 @@ cleanup: if (ret) testCleanupImages(); return ret; + +skip: + fputs("qemu-img is too old; skipping this test\n", stderr); + ret = EXIT_AM_SKIP; + goto cleanup; } typedef struct _testFileData testFileData; -- 1.8.1.2
