The helper functions decode_segment() and check_segment() are private
functions in uri.c and thus should not be accessible from outside. For
simplicity, these functions have been copied to client.c.
Made vpath %.c point to ../../src and repaired include path.
The common part of the Makefile has been moved to Makefile.common
to leverage Makefile creation for other platforms such as econotag.
coap_insert() now appends every item at the list's end, sorting must
be done explicitly using LL_SORT. As a side-effect, the new
implementation makes valgrind happy :-)
Directory examples/contiki now contains a small example server for
Contiki and a Makefile for platform minimal-net.
Build:
make contiki # clones Contiki
make server # creates the minimal-net coap server
Run:
Unfortunately, you have to run the server with sudo unless you
set CAP_NET_ADMIN for both, the server executable, and ifconfig
(sudo setcap cap_net_admin+pei ...).
sudo ./server
Then, add the server's interface address to the tap0 device and
optionally set a default route:
sudo ip -6 a a aaaa::1000 dev tap0
sudo ip -6 r a aaaa::/64 dev tap0
Although everything should work now, it does not. I had to send
router advertisements on tap0:
sudo radvd -C ./radvd.conf
Note that on Debian (and Ubuntu, and ...), radvd will not start
when IPv6 forwarding is disabled (which is usually the case on
end systems). Trying to enable like this did not work for me:
sudo sysctl -w net.ipv6.conf.tap0.forwarding=1
sudo sysctl -w net.ipv6.conf.tap0.mc_forwarding=1
Workaround (ugly): get the radvd sources, compile them and use that.
* resolve file resolution conflicts between lwip and libcoap in favor of
lwip by rearranging the makefile
* cover the config.h of a configured base libcoap with the local one
using the deprecated -I- gcc switch
* enable etharp (no idea why it wouldn't work ootb, the complete
server.c lwip-contrib copy needs to be reviewed)
* disable optimizations for easier debugging, enable -g3 for macro
expansions
This change contains a quick and dirty workaround for the following
bug that has been reported by Andrea Azzarà:
"When sending a file with a POST to a CoAP server, such as
./coap-client -m post coap://vs0.inf.ethz.ch:5683/large-create/ -b 64
-t 0 -f test
the M bit is not correctly set to 1."
Since the local_interface was added to the request handler callback,
the examples rd.c and etsi_iot_01.c were broken. This change fixes
rd.c and abandons etsi_iot_01.c (as it is very outdated).
Changed various functions to pass the local interface using the
new coap_endpoint_t abstraction. This change uses the functions
implemented earlier in commit 786ca6da (branch dcaf) but does not
use callback functions for network I/O.
This change closes bug #23 "server responds from wrong endpoint
(ipv6 address)" (POSIX only, CONTIKI and LWIP tbd).
Adding and removal of observes is now handled by libcoap. The application's
GET handler only needs to add the Observe option (see server.c:hnd_get_time()).
This new behavior is described in Section 4.6 of draft-ietf-core-observe-12.
The idea is to send a response with code 7.31 and the token to identify
the subscription.
