It was never intended to be committed. Lucky the high level Makefile was
correct so it didn't cause us problem when building xl.

There is no reason for a client to include a private header from libxl.
Remove the inclusion and define _GNU_SOURCE for {v,}asprintf in
xl_cmdimpl.c.

They should be treated like any other libraries installed on the build
host. Compiler options are set correctly to point to their locations.

It is included by xl.h. Previously it was using _paths.h from some other
place. We'd better generate one for xl as well.

used macros to xl_utils.h.

Move some commonly used functions to a new file. Prepend "x" to
function names to stick to consistent naming scheme.

The `xfoo' naming scheme is a reference to `xmalloc' et al, which
conventionally crash the program on failure.
I don't think you need to add this to every function in xl. It is
applicable only when there is an existing function which returns an
error code, which is wrapped by one which never fails.
Thanks,
Ian.

Move some commonly used functions to a new file.
find_domain requires access to global variable common_domname. Make that
non-static.
No functional change.

From: Wei Liu @ 2017-02-24 16:12 UTC (permalink / raw)
To: Xen-devel; +Cc: Wei Liu, Ian Jackson
Move all parsing code into xl_parse.c. Export the ones needed in
xl_parse.h.
Some notable changes other than code movement:
1. rename cpurange_parse to parse_cpurange;
2. provide a function to return shutdown action name.

Can you split that out so that I can review it separately from the
code motion ?
Thanks,

We want to consistently prefix functions to parse input with "parse_".
No functional change.

The array to map libxl_shutdown_action_to_shutdown to string is going to
be moved to a dedicated file.
Provide a function to do the translation so that we don't need to make
the array globally visible.

Would you mind calling this `libxl_cdrom.c' rather than `_cd' ?
The latter makes me think of chdir...

Can I have your ack if I rename it to libxl_cdrom.c?

To: Xen-devel; +Cc: Wei Liu, Ian Jackson
The new file also contains code for channel, which is just a console
in disguise.
Replace the call to vncviewer() with libxl_vncviewer_exec() directly in
main_vncviewer.

Again, please separate out the non-code-motion change.

We will need to move main_vncviewer to a different file where it has no
access to the helper vncviewer.
Call libxl_vncviewer_exec directly.

The new file also contains code for channel, which is just a console
in disguise.
Replace the call to vncviewer() with libxl_vncviewer_exec() directly in
main_vncviewer.

A collections of functions that don't warrant their own files.
Moving main_devd there requires lifting do_daemonize to xl_utils.c.

To: Xen-devel; +Cc: Wei Liu, Ian Jackson
Including create, reboot, shutdown, pause, unpause and destroy.
Lift a bunch of core data structures and function declarations to xl.h
because they are needed in both xl_cmdimpl.c and xl_vmcontrol.c.
