[Qemu-devel] [PATCH v3 0/3] chardev: Add -qmp-pretty


From: Max Reitz
Subject: [Qemu-devel] [PATCH v3 0/3] chardev: Add -qmp-pretty
Date: Fri, 14 Nov 2014 10:06:33 +0100

This series does not add new functionality. Adding a QMP monitor with
prettily formatted JSON output can be done as follows:

$ qemu -chardev stdio,id=mon0 -mon chardev=mon0,mode=control,pretty=on

However, this is rather cumbersome, so this series (its first patch)
adds a shortcut in the form of the new command line option -qmp-pretty.

Since the argument given to a monitor command line option (such as -qmp)
is parsed depending on its prefix and probably also depending on the
current phase of the moon, this is cleaner than trying to add a "switch"
to -qmp itself (in the form of "-qmp stdio,pretty=on").


Patch 3 makes uses of the new option in qemu-iotest 067 to greatly
increase maintainability of its reference output. Patch 2 extends the
QMP filter for qemu-iotests so it is able to filter out the QMP version
object in pretty mode.


v3:
- Patch 2: Cull useless "discard=0"

v2:
- Patch 2: Replaced the multi-line QMP_VERSION replacement written in
  bash by a nice sed script [Eric]


git-backport-diff against v1:

Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
