Trying to get the newest 2G+3G developments thru the test suites (including the
vty ones), I face a problem with this VTY definition from libosmo-sccp:
routing-key RCONTEXT DPC [si (aal2|bicc|b-isup|h248|isup|sat-isup|sccp|tup)]
[ssn SSN]
It turns out the square braces indicating optional parameters cannot contain
spaces.
To test, I created
foo [a] [b]
which works as
OsmoMSC(config-msc)# foo ?
[a] a
OsmoMSC(config-msc)# foo b
% Unknown command.
OsmoMSC(config-msc)# foo a
ok
OsmoMSC(config-msc)# foo a ?
[b] b
OsmoMSC(config-msc)# foo a b
ok
So far so good, but with:
foo [a AA] [b]
I get
OsmoMSC(config-msc)# foo ?
[a a
OsmoMSC(config-msc)# foo a
% There is no matched command.
OsmoMSC(config-msc)# foo a val
% Unknown command.
The way this would work is
foo [a] [AA] [b]
and means that I can issue either 'foo', 'foo a', 'foo a val' or 'foo a val b'.
Not that helpful really.
With above command
routing-key RCONTEXT DPC [si (aal2|bicc|b-isup|h248|isup|sat-isup|sccp|tup)]
[ssn SSN]
it seems to me it is intended as optionally providing none, si or both si and
ssn?
I guess we need separate command definitions:
routing-key RCONTEXT DPC
routing-key RCONTEXT DPC si (aal2|bicc|b-isup|h248|isup|sat-isup|sccp|tup)
routing-key RCONTEXT DPC si (aal2|bicc|b-isup|h248|isup|sat-isup|sccp|tup)
ssn SSN
Does that make sense?
Until we fix it, the vty tests will not be able to match up the vty doc
parameters and the python tests will fail.
I grepped for all square brace vty definitions we have; the only ones
attempting to include multiple args in square braces are in osmo_ss7_vty.c:
./libosmo-sccp/src/osmo_ss7_vty.c-265- "update route POINT_CODE MASK linkset
LS_NAME [priority PRIO] [qos-class (CLASS|default)]",
./libosmo-sccp/src/osmo_ss7_vty.c-781- "routing-key RCONTEXT DPC [si
(aal2|bicc|b-isup|h248|isup|sat-isup|sccp|tup)] [ssn SSN]}",
They aren't usable.
(the 'update route...' is part of the _sg vty command set and thus not caught
by osmo-msc or -bsc vty tests; osmo-stp has no vty tests so far, AFAICT)
These appear to be all square brace vty definitions, most enclose only a single
element and are fine:
