Re: [Qemu-devel] [PATCH v6 00/12] curl: fix curl read

[Richard W.M. Jones]

After discussion off-list, I've gone back and retested versions 4, 5,
and 6 of this patch.

I'm using the test script previously attached.

I'm using libguestfs (ada94eb9) & curl (ba9a6666) & qemu (6a4e177114)
all the latest from git.

I'm using a 6 GB Windows XP guest.  The web server is remote, over
quite slow wifi, and is running Apache 2.2.15 on RHEL 6.

I ran each test 3 times.

v4:

  Buffer I/O errors reported inside the appliance on each run.
  No segfault in qemu.

v5:

  Buffer I/O errors reported inside the appliance on each run.
  No segfault in qemu.

v6:

  Buffer I/O errors reported inside the appliance on each run.
  No segfault in qemu.

no patch (curl driver in upstream qemu):

  No errors.  Everything works.

So I guess what has happened is NOT a regression from v5 -> v6, but
that something has changed in my environment which has stopped this
patch from working.

I'm continuing to investigate.

Rich.
