[Crash-utility] [PATCH] extensions, ptdump: Add error message when the crash analyses a live system.

Hi, Indoh-san, ptdump does not support retrieving the trace data from the live system. However, the current error message does not tell so. When the crash analyses a live system, ptdump only displays the following message: crash> ptdump foo ptdump: invalid size request: 0 type: "read page for write" I think it's better to have a different message to let users know why error occurs. Therefore, I added the following error message in ptdump: crash> ptdump foo ptdump: no support on live system Please merge this patch. --- ptdump.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/ptdump.c b/ptdump.c index 8d5c367..44b19fb 100644 --- a/ptdump.c +++ b/ptdump.c @@ -491,6 +491,9 @@ cmd_ptdump(void) if (argcnt != 2) cmd_usage(pc->curcmd, SYNOPSIS); + if (ACTIVE()) + error(FATAL, "no support on live system\n"); + outdir = args[1]; if ((ret = mkdir(outdir, mode))) { fprintf(fp, "Cannot create directory %s: %d\n", outdir, ret); -- 1.8.3.1 Regards, -- Yuki Inoguchi
