Introducing keepalive similarly to Guannan around 2 years ago. Since
we want to introduce keepalive for every connection, it makes sense to
wrap the connecting function into new virsh one that can deal
keepalive as well.
Function vshConnect() is now used for connecting and keepalive added
in that function (if possible) helps preventing long waits e.g. while
nework goes down during migration.
This patch also adds the options for keepalive tuning into virsh and
fails connecting only when keepalives are explicitly requested and
cannot be set (whether it is due to missing support in connected
driver or remote server). If not explicitely requested, a debug
message is printed (hence the addition to virsh-optparse test).

This patch shuts up the following warning of clang

[-Werror,-Wincompatible-pointer-types-discards-qualifiers]
rl_readline_name = "virsh";

The warning happens because rl_readline_name on Mac OS X comes
from an old readline header that still uses 'char *', while it
is 'const char *' in readline 4.2 (April 2001) and newer.
Tested on Mac OS X 10.8.5 (clang-500.2.75) and Fedora 19 (gcc 4.8.1).

This patch adds instrumentation to allow modification of config of the
terminal in virsh and successful reset of the state afterwards.
The added helpers allow to disable receiving of SIGINT when pressing the
key sequence (Ctrl+C usualy). This normally sends SIGINT to the
foreground process group which kills ssh processes used for transport of
the data.
Noticed while reviewing another patch that had an accidental
mismatch due to refactoring. An audit of the code showed that
very few callers of vshCommandOpt were expecting a return of
-2, indicating programmer error, and of those that DID check,
they just propagated that status to yet another caller that
did not check. Fix this by making the code blatantly warn
the programmer, rather than silently ignoring it and possibly
doing the wrong thing downstream.
I know that we frown on assert()/abort() inside libvirtd
(libraries should NEVER kill the program that linked them),
but as virsh is an app rather than the library, and as this
is not the first use of assert() in virsh, I think this
approach is okay.

Commit a0b6a36f "fixed" what abfff210 broke (URI precedence), but
there was still one more thing missing to fix. When using virsh
parameters to setup debugging, those weren't honored, because at the
time debugging was initializing, arguments weren't parsed yet. To
make ewerything work as expected, we need to initialize the debugging
twice, once before debugging (so we can debug option parsing properly)
and then again after these options are parsed.
As a side effect, this patch also fixes a leak when virsh is ran with

Commit abfff210 changed the order of vshParseArgv() and vshInit() in
order to make fix debugging of parameter parsing. However, vshInit()
did a vshReconnect() even though ctl->name wasn't set according to the

the vshInit() into vshInitDebug() and vshInit().
One simple memleak of ctl->name is fixed as a part of this patch,

With this patch, include public headers in "" form is only allowed

This patch improves the error message after disconnecting from the
hypervisor and adds the close callback operations required not to leak
the callback reference.
The function is used to establish connection so it should be in the main
virsh file. This movement also enables further improvements done in next
patches.
Note that the "connect" command has moved from the host section of virsh to the
main section. It is now listed by 'virsh help virsh' instead of 'virsh help
host'.
Before closing the connection we unregister the close callback
to prevent a reference leak.

After we switched to C99 initialization, I noticed there were many
places where the specification of .flags parameter differed. After
going through many options and deciding whether to unify the
initialization to be '.flags = 0' or '.flags = VSH_OFLAG_NONE', I
realized both can be removed and it makes the code easier to go
through.
This patch adds a helper function with similar semantics to
vshCommandOptString that requests a string argument, but does some error
reporting without the need to do it in the functions themselves.
The error reporting also provides information about the parameter whose
retrieval failed.
This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.
The actual APIs are
int virDomainLxcOpenNamespace(virDomainPtr domain,
int **fdlist,
unsigned int flags);
int virDomainLxcEnterNamespace(virDomainPtr domain,
unsigned int nfdlist,
int *fdlist,
unsigned int *noldfdlist,
int **oldfdlist,
unsigned int flags);
which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.
NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.

For non-default connections (specified by the environment variable or
the command line option) we call virConnectOpenAuth without registering
the vshCatchDisconnect callback.
This calls vshReconnect instead which takes care of it.
Since we (ab)use vshReconnect for the default URI connection, if it
fails it might print 'Failed to reconnect to the hypervisor' even if we
were never connected before.
This changes it to only mention reconnection on the first try after
getting disconnected.
The termios struct exported by the termios.h header is used as an
argument for vshMakeStdinRaw(). The header isn't used anywhere in
tools/virsh-domain.c.
This patch adds the header to the header declaring vshMakeStdinRaw() and
removes other places in virsh.
Libvirt's helper API's when called directly don't raise the error so
that virsh remembers it. Subsequent calls to libvirt API's might reset
the error.
In case of schedinfo virDomainFree() in the cleanup section resets the
error when virTypedParameterAssignFromStr() fails.
This patch adds function vshSaveLibvirtError() that can be called after
calling libvirt helper APIs to ensure the error is remembered.
So far, none of the existing callers of vshStringToArray expected
the user to ever pass a literal comma; meanwhile, snapshot parsing
had rolled its own array parser. Moving the comma escaping into
the common function won't affect any existing callers, and will make
this function reusable for adding memory handling to snapshot parsing.
As a bonus, the testsuite was already testing snapshot parsing, so
the fact that the test still passes means that we are now giving
testsuite exposure to vshStringToArray.
* tools/virsh-snapshot.c (vshParseSnapshotDiskspec): Move ,,

* tools/virsh.c (vshStringToArray): ...into common function.
Also, vshStrdup can't fail.

Most likely this problem arose because of the patch I pushed
in gnulib commit e07d7c40f3ca5ec410cf5aa6fa03cfe51e712039.
Previously, gnulib required timeval's tv_sec to be
the same size as time_t. But now, it requires only that
tv_sec be big enough to hold a time_t.
This patch was needed for Emacs. Without the patch, gnulib
replaced struct timeval on OpenBSD, and this messed up
utimens.c, and Emacs wouldn't build.
Alternatively, gnulib could substitute its own struct timeval
for the system's, wrapping every struct timeval-using function
(gettimeofday, futimesat, futimes, lutimes, etc. That'd be
more work, though. And it would introduce some performance
issues with gettimeofday, which is supposed to be fast.
I've been trying to get away from using struct timeval,
and to use the higher-resolution struct timespec instead,
so messing with these obsolescent interfaces has been
lower priority for me. But if someone wants to take the
more-ambitious approach that'd be fine, I expect.
For this particular case, though, how about if we avoid
the problem entirely? libvirt doesn't need to use struct
timeval here at all. It makes libvirt smaller and probably
faster, and it ports to OpenBSD without messing with gnulib.
Now that vshCommandRun() checks for the connection automaticaly, remove
all of the redundant checks in the code.
vshConnectionUsability() no longer needs to be exported and this patch
marks it static.
Almost each virsh command uses the function vshConnectionUsability
before doing anything, to check if the connection is "alive". Commands
that don't need an conection are already conveniently marked with
VSH_CMD_FLAG_NOCONNECT. We can automaticaly check for the connection
before calling any remote command so we don't forget to do so.
This patch also upgrades the connection check to use virConnectIsAlive
along with the current approach.
When executing virsh -t <command> the reported timing was off
by 3 orders of magnitude if the command took more than one
second.
