      qemu-log: default to stderr for logging output · 989b697d
      由 Peter Maydell 提交于 
      Switch the default for qemu_log logging output from "/tmp/qemu.log"
to stderr. This is an incompatible change in some sense, but logging
is mostly used for debugging purposes so it shouldn't affect production
use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log"
to the command line.

This change requires us to:
 * update all the documentation/help text (we take the opportunity
   to smooth out minor inconsistencies between the phrasing in
   linux-user/bsd-user/system help messages)
 * make linux-user and bsd-user defer to qemu-log for the default
   logging destination rather than overriding it themselves
 * ensure that all logfile closing is done via qemu_log_close()
   and that that function doesn't close stderr
as well as the obvious change to the behaviour of do_qemu_set_log()
when no logfile name has been specified.

      hmp: Disable chardev-add and chardev-remove · 8a14952c
      由 Markus Armbruster 提交于 
      As a general rule, HMP commands must be built on top of the QMP API.
Luiz and others have worked long & hard to make HMP conform to this
rule.

Commit f1088908 added chardev-add, in violation of this rule.  QMP
command chardev-add was added right before, with minimal features, and
the idea to complete it step by step, then switch over the HMP command
to use it.

Unfortunately, we're not there, yet, and we don't want to release with
chardev-add in a "HMP is more powerful than QMP" state.

Disable the HMP command for now, along with its chardev-remove buddy.

      qemu-char: Saner naming of memchar stuff & doc fixes · 3949e594
      由 Markus Armbruster 提交于 
      New device, has never been released, so we can still improve things
without worrying about compatibility.

Naming is a mess.  The code calls the device driver CirMemCharDriver,
the public API calls it "memory", "memchardev", or "memchar", and the
special commands are named like "memchar-FOO".  "memory" is a
particularly unfortunate choice, because there's another character
device driver called MemoryDriver.  Moreover, the device's distinctive
property is that it's a ring buffer, not that's in memory.  Therefore:

* Rename CirMemCharDriver to RingBufCharDriver, and call the thing a
  "ringbuf" in the API.

* Rename QMP and HMP commands from memchar-FOO to ringbuf-FOO.

* Rename device parameter from maxcapacity to size (simple words are
  good for you).

* Clearly mark the parameter as optional in documentation.

* Fix error reporting so that chardev-add reports to current monitor,
  not stderr.

* Replace cirmem in C identifiers by ringbuf.

* Rework documentation.  Document the impact of our crappy UTF-8
  handling on reading.

* QMP examples that even work.

I could split this up into multiple commits, but they'd change the
same documentation lines multiple times.  Not worth it.

      qapi: Convert migrate · e1c37d0e
      由 Luiz Capitulino 提交于 
      The migrate command is one of those commands where HMP and QMP completely
mix up together. This made the conversion to the QAPI (which separates the
command into QMP and HMP parts) a bit difficult.

The first important change to be noticed is that this commit completes the
removal of the Monitor object from migration code, started by the previous
commit.

Another important and tricky change is about supporting the non-detached
mode. That is, if the user doesn't pass '-d' the migrate command will lock
the monitor and will only release it when migration is finished.

To support this in the new HMP command (hmp_migrate()), it is necessary
to create a timer which runs every second and checks if the migration is
still active. If it is, the timer callback will re-schedule itself to run
one second in the future. If the migration has already finished, the
monitor lock is released and the user can use it normally.

All these changes should be transparent to the user.
