Re-enable the check on ambiguos properties but this time manage perfect
matches (i.e., the full property name has been typed) that are prefix
of other properties.
Test case:
nmcli --complete-args connection add type wifi wifi.
Here "wifi" is a property alias that is also prefix of the property
alias "wifi-sec".
When parsing arguments of "connection add" we first read the available
property-value pairs and then check if the --ask option was passed in
order to aid in the fill process of a new connection.
Anyway, if there are no property-value tuples at all, we don't even
check the --ask option, returning with error.
Fix this just checking if any arg is there (argc) before invoking
read_connection_properties().
If we found that setting name prefix is in fact unambiguous and return
the completion string for that setting we were freeing the string upon
the return. That looks like a typo.
Fixes "nmcli --complete-args add type wifi wifi."
^^^^ not ambiguous
It allows us to clean up the nmcli "c add" section considerably.
We list the old-fashioned aliases in a separate section that applies to both
"nmcli c add" and "nmcli c modify".
The section is now nicely cross-linked with nm-settings in HTML
rendering.
This is a huge refactoring in attempt to 1.) reduce the horrible redundancy in
the connection addition path and 2.) reduce confusion between various sources
of property value (command line, properties, interactive mode).
* The conversions from the strings was done all over the place:
settings.c already does for all sensible properties.
The rest is removed.
* The validations are done randomly and redundantly:
server does some validation, and per-property client validations
useful for interactive mode are done in settings.c
The rest is removed.
* The information about defaults and required options was redundantly
scattered in per-type completion functions and interactive mode
questionnaries. This is now driven by the option_info[] table.
In general, we do our best to just map the command line options to
properties and allow mixing them. For the rest there's the
check_and_set() callbacks (basically to keep compatibility with previous
nmcli versions). This this is now all possible:
$ nmcli c add type ethernet ifname '*'
This always worked
$ nmcli c add type bond-slave save no -- connection.autoconnect no
The "save" and "--" still work
$ nmcli c add connection.type ethernet ifname eth0
Properties can now be used
$ nmcli c add type ethernet ip4 1.2.3.4 mac 80:86:66:77:88:99 con-name whatever
There's no implementation mandated order of the properties (the type
still must be known to determine which properties make sense)
$ nmcli --ask c add type ethernet ip4 1.2.3.4 mac 80:86:66:77:88:99 con-name whatever
The interactive mode asks only for properties that weren't specified
on command line
Complete the property as we parse the list of properties. This makes it
possible to actually complete an unfinished property. E.g:
$ nmcli --complete c modify enp0s25 +ipv6.addr
+ipv6.addresses +ipv6.addr-gen-mode
Make property autocompletion take a prefix and modifier flags.
This will make it easier to complete an unfinished property name
(possibly accompanied by a modifier) without shell trickery.
nmcli bash autocompletion leveraged on "nmcli connection edit", "print"
to retrieve the specific properties of a connection. Anyway, the
interactive editor is smart and just prints the used components, so in a
connection where 802.1x is not enabled we had no autocompletion.
Solved adding an "hidden" command "nmcli --complete connection modify"
as suggested in bgo #724860 in order to retrieve ALL the available
properties for use in autocompletion.
Here patch from L.Rintel has been merged to make che --complete option
global to nmcli (first version was local to "connection modify").

At various places, nmcli requires to specify a VPN type by name, for example
$ nmcli connection add type vpn ifname '*' vpn-type $VPN_TYPE
This $VPN_TYPE used to be a hard-coded list of known VPN plugin names.
But actually, it should be a VPN service-type. A service-type used to be
the D-Bus name of the VPN plugin. Now, with multiple VPN support that
is no longer the case, but it still has the form of a D-Bus bus name.
Alternativley, it could be an alias, which is just a way for plugins
to support multiple service-types.
Fix that, to support fully qualified service-types in the form
of D-Bus bus names. Also, support lookup by name, in which case
the present plugin-info instances are searched.
Finally, support a list of hard-code short-names.
All the logic how to translate a short-name to a fully qualified
service-type is now inside libnm, so that various user agree on
those names and don't have to hard-code them each.
As explained in the function comment, a NULL value for @val is
acceptable. Otherwise:
$ nmcli connection edit
(process:2276): nmcli-CRITICAL **: check_valid_name: assertion 'val' failed
Fixes: fb8fe1d8cb
Instead of using (only) a hard-coded list of VPN types,
prefer lookup the VPN settings from the .name files.
Still, fallback to a hard-coded list if the plugin cannot
be found, because for connection-add we currently don't
actually need the plugin installed.
When performing NM package upgrade the new version of nmcli will be immediately
available while NM daemon will not, as it would not restart in order to avoid
to disrupt connectivity. This could create issues with tools leveraging
on nmcli output (till reboot). As apart from this case it is very unlikely
that a user can have this nmcli / NM daemon version mismatch situation,
the check could cause more harm than benefit in real user case
scenarios.

We actually don't want to understand these options unless the legacy
*-slave types are used. The properties should be used directly instead.

This basically undoes most of what has been done in commit 00e0fffea2.
In previous releases 'nmcli connection m' was interpreted as 'modify',
but recently the monitor command was introduced with a higher
priority, changing the behavior when the abbreviated form is
used.
Restore the old behavior.
https://bugzilla.redhat.com/show_bug.cgi?id=1316120
Use g_error_matches() where we're testing error codes. In particular,
use it rather than looking at only ->code and not also ->domain, which
is just wrong.
[thaller@redhat.com: rebase and modify original patch]
Functions that take a GError** MUST fill it in on error. There is no
need to check whether error is NULL if the function it was passed to
had a failing return value.
Likewise, a proper GError must have a non-NULL message, so there's no
need to double-check that either.

- All internal source files (except "examples", which are not internal)
should include "config.h" first. As also all internal source
files should include "nm-default.h", let "config.h" be included
by "nm-default.h" and include "nm-default.h" as first in every
source file.
We already wanted to include "nm-default.h" before other headers
because it might contains some fixes (like "nm-glib.h" compatibility)
that is required first.
- After including "nm-default.h", we optinally allow for including the
corresponding header file for the source file at hand. The idea
is to ensure that each header file is self contained.
- Don't include "config.h" or "nm-default.h" in any header file
(except "nm-sd-adapt.h"). Public headers anyway must not include
these headers, and internal headers are never included after
"nm-default.h", as of the first previous point.
- Include all internal headers with quotes instead of angle brackets.
In practice it doesn't matter, because in our public headers we must
include other headers with angle brackets. As we use our public
headers also to compile our interal source files, effectively the
result must be the same. Still do it for consistency.
- Except for <config.h> itself. Include it with angle brackets as suggested by
https://www.gnu.org/software/autoconf/manual/autoconf.html#Configuration-Headers
