35966308b5 virsh: Fix regression with duplicated error messages
Commit 4f4c3b13 (v3.3) fixed an issue where performing cleanup of
libvirt objects could sometimes lose error messages, by adding code
to copy the libvirt error into last_error prior to cleanup paths.
However, it caused a regression: on other paths, some errors are now
printed twice, if libvirt still remembers in its thread-local
storage that an error was set even after virsh cleared last_error.
For example:

$ virsh -c test:///default snapshot-delete test blah
error: Domain snapshot not found: no domain snapshot with matching name 'blah'
error: Domain snapshot not found: no domain snapshot with matching name 'blah'

Fix things by telling libvirt to discard any thread-local errors at
the same time virsh prints an error message (whether or not the libvirt
error is the same as what is stored in last_error).

Update the virsh-undefine testsuite (partially reverting portions of
commit b620bdee, by removing -q, to more easily pinpoint which commands
are causing which messages), now that there is only one error message
instead of two.

5165ff0971 src: More cleanup of some system headers already contained in internal.h
All of the ones being removed are pulled in by internal.h. The only
exception is sanlock which expects the application to include <stdint.h>
before sanlock's headers, because sanlock prototypes use fixed width
int, but they don't include stdint.h themselves, so we have to leave
that one in place.

0d1c1a74b7 vshReadlineParse: Ignore vshReadlineOptionsGenerator for VSH_OT_ARGV options
Currently the VSH_OT_ARGV options don't support complete, But some of
VSH_OT_ARGV options are gonna support complete in upcoming patches.

Once applied the upcoming completion patches for VSH_OT_ARGV options, If
we don't ignore VSH_OT_ARGV here, The vshReadlineOptionsGenerator will
be called, Hence complete output will consist of the result by command
completer + the result by option completer, It's confusing.
e.g.
    $ virsh domstats --domain <TAB><TAB>
    --backing     --interface      --list-paused      --perf      --vcpu
    --balloon     leap42.3         --list-persistent  --raw       win10

846d3b5874 vshCommandOpt: Do more checking if skipChecks is set
Currently if cmd->skipChecks is set (done only from completers)
some basic checks are skipped because we're working over
partially parsed command. See a26ff63ae4 for more detailed
explanation. Anyway, the referenced commit was too aggressive in
disabling checks and effectively returned success even in clear
case of failure. For instance:

  # domif-getlink --interface <TAB><TAB>

causes virshDomainInterfaceCompleter() to be called, which calls
virshDomainGetXML() which eventually calls
vshCommandOptStringReq(.., name = "domain"); The --domain
argument is required for the command and if not present -1 should
be returned to tell the caller the argument was not found. Well,
zero is returned meaning the argument was not found but it's not
required either.

just before the wrapper invokes the helpers, it performs the search,
either for command group or for the command itself, except the result is

2e688d96a4 vshCommandStringParse: Allow retrieving partial result
In the future, this function is going to be called from
vshReadlineParse() to provide parsed input for completer
callbacks. The idea is to allow the callbacks to provide more
specific data. For instance, for the following input:

  virsh # domifaddr --domain fedora --interface <TAB><TAB>

the --interface completer callback is going to be called. Now, it
is more user friendly if the completer offers only those
interfaces found in 'fedora' domain. But in order to do that it
needs to be able to retrieve partially parsed result.

b98b3b742b vsh: Drop conditional error reporting in vshErrorHandler
First, since commit 834c5720 the error reporting within the vshErrorHandler
doesn't work because there was a lot of renaming going on (dull mechanical
renaming without much thinking about it, yep - shame on me) and so the original
env variable VIRSH_DEBUG got renamed to VSH_DEBUG which we don't support nor
document anywhere. Second, by specifying this env variable, the last libvirt
error gets reported twice despite the fact we say the error reporting should be
deferred until the command finishes, and last but not least the vintage code's
logic is a bit 'odd', since the error would get reported iff the env variable
is set, even if the value should be equal to our DEFAULT value in which case it
doesn't make sense that we behave differently when an env variable is set to
some value and when there's no env variable at all but we use the same value
automatically as default.

Commit id 'dcfdf341' passes 'opts_need_arg' and 'opts_seen' to

Instead the static 'const_opts_need_arg' and 'const_opts_seen' values
should be passed.

By passing unitialized values leads to not finding possible options
for simpler commands (domfsfreeze for example), where if you're in
a virsh shell using command line completion - you'll get a list of
files in your current directory instead of two options --domain and

bcfa2f427d vsh: Write out history on "quit" or "exit" in interactive mode
https://bugzilla.redhat.com/show_bug.cgi?id=1379895

Introduced by commit id '834c5720'.

During the code motion and creation of vsh.c, the function 'vshDeinit()'
in the (new) vsh.c was altered from whence it came in virsh.c such that
calling 'vshReadlineDeinit(ctl)' was conditional on "ctl->imode".

This causes a problem for the interactive running if the "quit" and "exit"
commands are used because 'cmdQuit' will clear ctl->imode, thus when the
interactive loop in main() of virsh.c exits because ctl->mode is clear and
virshDeinit is called which calls vshDeinit, the history file is now not
written. Conversely, if one had exited the interactive loop via pressing
<ctrl>D the file would be created because loop control is broken on EOF
and ctl->imode is not set to false.

This patch will remove the conditional call to vshReadlineDeinit and
restore the former behaviour.

Also, by removing the 'else' block, the declarations need to be moved to
beginning of the function block to conform with our guidelines.

c91cddb6f7 vsh: vshCmddefHelp: Drop unnecessary variable 'help'
Since it's used on a single place only, it can easily be replaced by the right
side of the original assignment.

ebb402a7c4 vsh: Enforce checking for missing help string
The intention is to move vshCmddefCheckInternals out of vshCmddefOptParse to
our test suite. First step to do that is to enforce checking for an existing
help string (that also means it's non-empty) in a command because a command
without a help is not much of a use.

cbbaa17faf tools: Pass opaque data in vshCompleter and introduce autoCompleteOpaque
This patch changes the signature of vshCompleters, allowing to pass along
some data that we might want to along with the completers; for example,
we might want to pass the autocomplete vshControl along with the
completer, in case the completer requires a connection to libvirtd.

731ee28c5b virsh: Complete multiple options when any one option requires data
Before this patch:
    virsh # start --domain dom1 [TAB][TAB] <- offers filename completion
    virsh # start --domain [TAB][TAB] <- offers filename completion

After this patch:
    virsh # start --domain dom1 [TAB][TAB] <- offers command completion
    virsh # start --domain [TAB][TAB] <- calls domain completer if
    defined, otherwise falls back to filename completion
