[libvirt] [PATCH] tests: Use system() for test-wrap-argv.pl

virCommand doesn't buy us anything here, and this simplifies the code. There's another usage of system() in testutils.c already FWIW, though it predates virCommand --- Had this sitting in a branch from an earlier discussion... I figure system() is safe in the test suite but I'm not going to argue if someone feels strongly the other way tests/testutils.c | 26 ++++++-------------------- 1 file changed, 6 insertions(+), 20 deletions(-) diff --git a/tests/testutils.c b/tests/testutils.c index 79d0763..7664b06 100644 --- a/tests/testutils.c +++ b/tests/testutils.c @@ -432,28 +432,14 @@ virtTestCaptureProgramOutput(const char *const argv[] ATTRIBUTE_UNUSED, static int virTestRewrapFile(const char *filename) { - int ret = -1; - char *outbuf = NULL; - char *script = NULL; - virCommandPtr cmd = NULL; - - if (virAsprintf(&script, "%s/test-wrap-argv.pl", abs_srcdir) < 0) - goto cleanup; - - cmd = virCommandNewArgList(script, filename, NULL); - virCommandSetOutputBuffer(cmd, &outbuf); - if (virCommandRun(cmd, NULL) < 0) - goto cleanup; + char *cmd; - if (virFileWriteStr(filename, outbuf, 0666) < 0) - goto cleanup; + /* The 'echo' syntax lets us read and write the file in one shot */ + if (virAsprintf(&cmd, "echo \"$(%s/test-wrap-argv.pl %s)\" > %s", + abs_srcdir, filename, filename) < 0) + return -1; - ret = 0; - cleanup: - VIR_FREE(script); - virCommandFree(cmd); - VIR_FREE(outbuf); - return ret; + return system(cmd); } /** -- 2.7.3
