The commands which requires a pool to perform any action for a volume is
throwing a segfault when you pass the volume name before a pool name or
without the argument '--pool'.
An example that works:
virsh # vol-list loops-pool
Name Path
-------------------------------------------------------------------
loop0 /mnt/loop0
virsh # vol-info --pool loops-pool lo<TAB>
An example that does not work:
virsh # vol-list loops-pool
Name Path
-------------------------------------------------------------------
loop0 /mnt/loop0
virsh # vol-info lo<TAB>
Segmentation Fault
The example 'vol-info' can be executed as 'vol-info loop0 --pool
loops-pool'. So, this commit fixes this problem when the arguments are
inverted and avoids the segfault.

In some cases there's dangling backward slash at the end of multi
line macros. While technically the code works, it will stop if
some empty lines are removed.
Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

For the virsh pool-{define|create}-as command, let's allow using
--secret-uuid on the command line as an alternative to --secret-usage
(added for commit id '8932580'), but ensure that they are mutually
exclusive.
This commit adds new events for two methods and operations: *PoolBuild() and
*PoolDelete(). Using the event-test and the commands set below we have the
following outputs:
$ sudo ./event-test
Registering event callbacks
myStoragePoolEventCallback EVENT: Storage pool test Defined 0
myStoragePoolEventCallback EVENT: Storage pool test Created 0
myStoragePoolEventCallback EVENT: Storage pool test Started 0
myStoragePoolEventCallback EVENT: Storage pool test Stopped 0
myStoragePoolEventCallback EVENT: Storage pool test Deleted 0
myStoragePoolEventCallback EVENT: Storage pool test Undefined 0
Another terminal:
$ sudo virsh pool-define test.xml
Pool test defined from test.xml
$ sudo virsh pool-build test
Pool test built
$ sudo virsh pool-start test
Pool test started
$ sudo virsh pool-destroy test
Pool test destroyed
$ sudo virsh pool-delete test
Pool test deleted
$ sudo virsh pool-undefine test
Pool test has been undefined

Commit id '27758859' introduced the "NO_OVERWRITE" flag check for
file system backends; however, the implementation, documentation,
and algorithm was inconsistent. For the "flag" description for the
API the flag was described as "Do not overwrite existing pool";
however, within the storage backend code the flag is described
as "it probes to determine if filesystem already exists on the
target device, renurning an error if exists".
The code itself was implemented using the paradigm to set up the
superblock probe by creating a filter that would cause the code
to only search for the provided format type. If that type wasn't
found, then the algorithm would return success allowing the caller
to format the device. If the format type already existed on the
device, then the code would fail indicating that the a filesystem
of the same type existed on the device.
The result is that if someone had a file system of one type on the
device, it was possible to overwrite it if a different format type
was specified in updated XML effectively trashing whatever was on
the device already.
This patch alters what NO_OVERWRITE does for a file system backend
to be more realistic and consistent with what should be expected when
the caller requests to not overwrite the data on the disk.
Rather than filter results based on the expected format type, the
code will allow success/failure be determined solely on whether the
blkid_do_probe calls finds some known format on the device. This
adjustment also allows removal of the virStoragePoolProbeResult
enum that was under utilized.
If it does find a formatted file system different errors will be
generated indicating a file system of a specific type already exists
or a file system of some other type already exists.
In the original virsh support commit id 'ddcd5674', the description
for '--no-overwrite' within the 'pool-build' command help output
has an ambiguous "of this type" included in the short description.
Compared to the longer description within the "Build a given pool."
section of the virsh.pod file it's more apparent that the meaning
of this flag would cause failure if a probe of the target already
has a filesystem.
So this patch also modifies the short description to just be the
antecedent of the 'overwrite' flag, which matches the API description.
This patch also modifies the grammar in virsh.pod for no-overwrite
as well as reworking the paragraph formats to make it easier to read.

When using
virsh net-event non-existing-net
the error message says that 'either --list or event type is required'
This is misleading as 'virsh net-event $valid-event-type' is not going
to work either. What is expected is 'virsh net-event --event
$valid-event-type'
This commit fixes the string in pool-event, nodedev-event, event, and
net-event.
Turn various vshPrint() informative messages into vshPrintExtra(), so
they are not printed when requesting the quiet mode; neither XML/info
outputs nor the results of commands are affected.
Also change the expected outputs of the virsh-undefine test, since virsh
is invoked in quiet mode there.
Some informative messages might still be converted (and thus silenced
when in quiet mode), but this is an improvements nonetheless.

The VIR_STORAGE_POOL_EVENT_REFRESHED constant does not
reflect any change in the lifecycle of the storage pool.

event set, but rather be a top level event in its own

to replace it.

Rather than continually cut-n-paste the strings into each command,
create a common macro to be used generically. The macro will take a
single argument _helpstr for the less common help string for each
command option. Note that only file options using "OT_DATA" and
"OFLAG_REQ" will be replace - others are left as is.
Signed-off-by: John Ferlan <jferlan@redhat.com>
The macro is slightly adjusted to add an argument "_helpstr". This
will be passed as a translation macro string since other uses of the
option may not have the same exact help string (such as is the case
when the uuid is not suppliable for create commands).
In virsh-pool.c - we'll create a singular VIRSH_COMMON_OPT_POOL_FULL
in order to pass along the 'N_("pool name or uuid")'
In virsh-volume.c there will be a VIRSH_COMMON_OPT_POOL_FULL and a
VIRSH_COMMON_OPT_POOL_NAME, which passes 'N_("pool name")' for
the commands that can only pass a name. There will also be a
VIRSH_COMMON_OPT_POOL_OPTIONAL which is used for the command
options which use OT_STRING and don't require the --pool argument.

Utilize recently added VIR_STORAGE_POOL_CREATE_WITH_BUILD* flags in
order to pass the flags along to the virStoragePoolCreateXML and
virStoragePoolCreate API's.
This affects the 'virsh pool-create', 'virsh pool-create-as', and
'virsh pool-start' commands. While it could be argued that pool-start
doesn't need the flags, they could prove useful for someone trying to
do one command build --overwrite and start command processing or
essentially starting with a clean slate.
NB:
This patch is loosely based upon code originally authored by Osier
Yang that were not reviewed and pushed, see:
https://www.redhat.com/archives/libvir-list/2012-July/msg00497.html
Although they both are the same now, a future patch will add new options
to pool-create-as. So create a common macro to capture commonality, then
use that in the command specific structure.
Although not currently used in more than one command, it soon will be
so create a common macro to be used in the new command location.
Additionally, add the ".flags = 0," for both to match the expections
of the structure being predefined.
Rather than continually cut/paste the "file" option for pool command
option structures, generate a macro which will commonly define it for
any command. Then of course use that macro.
Rather than continually cut/paste the "pool" option for pool command
option structures, generate a macro which will commonly define it for
any command. Then of course use that macro.
In order to share as much virsh' logic as possible with upcomming
virt-admin client we need to split virsh logic into virsh specific and
client generic features.
Since majority of virsh methods should be generic enough to be used by
other clients, it's much easier to rename virsh specific data to virshX
than doing this vice versa. It moved generic virsh commands (including info
and opts structures) to generic module vsh.c.
Besides renaming methods and structures, this patch also involves introduction
of a client specific control structure being referenced as private data in the
original control structure, introduction of a new global vsh Initializer,
which currently doesn't do much, but there is a potential for added
functionality in the future.
Lastly it introduced client hooks which are especially necessary during
client connecting phase.

command in order to define the 3 elements required in order to add
an auth element, such as:
<auth type='chap' username='myuser'>
<secret usage='libvirtiscsi'/>

According to comments in parsing functions, optional options should be
specified *after* required ones. It makes sense and help output looks
cleaner. The only exceptions are options with type == VSH_OT_ARGV.

Since 0766783abb
Coverity complains that the EDIT_FREE definition results in DEADCODE.
As it turns out with the change to use the EDIT_FREE macro the call to
vir*Free() wouldn't be necessary nor would it happen...
Prior code to above commitid would :
vir*Ptr foo = NULL;
...
foo = vir*GetXMLDesc()
...
vir*Free(foo);
foo = vir*DefineXML()
...
And thus the free was needed. With the change to use EDIT_FREE the
same code changed to:
vir*Ptr foo = NULL;
vir*Ptr foo_edited = NULL;
...
foo = vir*GetXMLDesc()
...
if (foo_edited)
vir*Free(foo_edited);
foo_edited = vir*DefineXML()
...
However, foo_edited could never be set in the code path - even with
all the goto's since the only way for it to be set is if vir*DefineXML()
succeeds in which case the code to allow a retry (and thus all the goto's)
never leaves foo_edited set
All error paths lead to "cleanup:" which causes both foo and foo_edited
to call the respective vir*Free() routines if set.

Implement ZFS storage backend driver. Currently supported
only on FreeBSD because of ZFS limitations on Linux.
Features supported:
- pool-start, pool-stop
- pool-info
- vol-list
- vol-create / vol-delete
Pool definition looks like that:
<pool type='zfs'>
<name>myzfspool</name>
<source>
<name>actualpoolname</name>
</source>
</pool>
The 'actualpoolname' value is a name of the pool on the system,
such as shown by 'zpool list' command. Target makes no sense
here because volumes path is always /dev/zvol/$poolname/$volname.
User has to create a pool on his own, this driver doesn't
support pool creation currently.
A volume could be used with Qemu by adding an entry like this:
<disk type='volume' device='disk'>
<driver name='qemu' type='raw'/>
<source pool='myzfspool' volume='vol5'/>
<target dev='hdc' bus='ide'/>
</disk>
In "src/conf/" there are many enumeration (enum) declarations.
Similar to the recent cleanup to "src/util" directory, it's
better to use a typedef for variable types, function types and
other usages. Other enumeration and folders will be changed to
typedef's in the future. Most of the files changed in this
commit are related to storage (storage_conf) enums.
