Previously reading from socket would block if no data were sent by
the server. Use non-blocking read for set and get operations.

This option only served to demonstrate possibility of manually selecting
<id> field in CTRL protocol. Since the transition to generic ipa module
this is no longer exposed so the option became a no-op. Correspondingly
there's no need to explicitly initialize the RNG - the Ctrl class
handles random <id> generation internally.

Add web application exposing Control Interface over web. All of SET, GET
and TRAP are fully supported.
Notice: TRAP is converted into 'Server-sent events' according to RFC
6202, see also https://www.w3.org/TR/eventsource/ - this requires
corresponding client.
Due to use of special prefix modified version of python
eventsource-client is necessary ATM.

Add get_var and set_var functions which handle requested variable while
checking for proper response and id. Split header handling into separate
function.

According to documentation for Control Interface Protocol <id> is "A
numeric identifier, uniquely identifying this particular operation",
hence it's best to be illustrated with random integer - use it as
default.
Fix override of id with previously used python-specific objects' id.

This adds a very basic, use once example in python on how to connect
and deal with the app specific payload and messages. The code is not
complete as the invokeId should be patched according to the initial
invoke. This excercise is left to future readers of that code.

Those were relevant in 2008/2009, but not today...
Also, move hlrsync to the contrib directory

* osmo-bsc and osmo-bsc-mgcp are needed to run

controlled via systemctl

We might be offered multiple codecs by the remote and need to
switch between them once we receive data. Do this by moving it
to a struct so we can separate between proposed and current
codec. In SDP we can have multiple codecs but a global ptime.
The current code doesn't separate that clearly instead we write
it to the main codec.
|
|
That way the services can be enabled with
> systemctl enable <service>

Jacob pointed out that "free_endp" refers to the memory of
the endpoint being freed. What we want is actually a way to
release an endpoint (and the resource it allocated) or in
the case of the testcase/testapp initialize the data structure
correctly. Introduce two names for that.

This patch moves the files relevant to transcoding from
src/osmo-bsc_mgcp to src/libmgcp and src/include/openbsc. Makefiles
and include directives are being updated accordingly.

This modification allows it to set the number of samples per packet
that is written to the output.

The current transcoder implemenation always does a 1:1 recoding
concerning the duration of a packet. So RTP timestamps and sequence
numbers are not modified.
This is not sufficient in some cases, e.g. when the BTS does only
allow for a single fixed ptime.
This patch decouples encoding from decoding and moves the decoded
samples to the state structure so that samples can be combined or
drain according to the packaging of incoming and outgoing packets.
This patch incorporates parts of Holger's experimental fixes in
0e669e05^..9eba68f9.

This adds a --frame-size option to read payload binary files with a
fixed frame size directly. The file must not contain RTP headers.
In addition '--rate' and '--duration' can be used to configure the
timing.

There is the wrong record field selection being used to extract the
default value. It returns the tuple offset instead of the value.
This patch fixes this.

This tool provides the following features:
- Output formats: state, C arrays
- Optionally take RTP payload from existing state files
- Generate streams with RTP timestamp jumps and/or delays
- Set/change SSRC or payload type
Requires erlang to be installed.
Example:
Generate 300 packets, set playout time offset to 1s, set
RTP timestamp offset to 8000 (1s), generate another 100
packets, the RTP payload is copied from rtp.state:
./gen_rtp_header.erl --type=98 --file=rtp.state --
0 300 0 --delay=1.0 100 8000

This patch adds optional parameters to pass the state file, the
destination address (default 127.0.0.1), the destination port
(default 4000), the source port (default 0). So it is called as
follows:
gst rtp_replay.st -a [FILE [HOST [SOURCEPORT [DESTPORT]]]]
In addition, nonexistant FILEs are no longer created but opened
read-only instead.

The test scripts warn about missing documentation, untested configs,
check common errors, and stub out testing individual VTY commands.

This can be used to throw the data into GNUplot. It collects
the time (from the start of the trace), the buffer data in kbyte
and the number of buffered PDUs. It is assuming that no PDU
is delivered toward the target.
