high level client crash #98

Closed sanbeam closed 7 years ago

sanbeam commented 7 years ago

Client crashes with the following issue.

{"devAddr":{"adapter":2,"flags":0,"ifindex":0,"port":0,"addr":""},"addr":{"adapter":2,"flags":0,"ifindex":0,"port":0,"addr":""},"connType":131072,"identity":[],"result":255,"sequenceNumber":0,"resourceUri":"/oic/res","rcvdVendorSpecificHeaderOptions":[]} /home/sanjeev/source/jlr/node_modules/iotivity-node/lib/csdk.js:39 throw theError; ^

Error: findResources: Unexpected response

sanbeam commented 7 years ago

Bump. Someone please look into this.

gabrielschulhof commented 7 years ago

It looks like some server on the network is issuing OC_STACK_ERROR in response to a resource discovery. I would say check the server, and attach an error handler to the client so it doesn't end up throwing a fatal exception.

rzr commented 7 years ago

Discovery worked for me on 1.2 using high level client / server... but then hang, I will have to investigate too

sanbeam commented 7 years ago

Just curious. Is security enabled by default ?

sanbeam commented 7 years ago

Just curious. Is security enabled by default ? If yes, how do i get insecure version at npm install ?

rzr commented 7 years ago

upstream and meta-oic have SECURED=0 by default on 1.2.1 and under, I aligned to that

gabrielschulhof commented 7 years ago

If you want to build with SECURED=0 you have to build iotivity externally, then export OCTBSTACK_CFLAGS and OCTBSTACK_LIBS.

sanbeam commented 7 years ago

Thanks for confirming. I think these two were the issues. I ll test and update soon.

sanbeam commented 7 years ago

Did the following steps.

  1. package.json : "iotivity-node": "git+https://github.com/otcshare/iotivity-node#maintenance"

  2. git clone https://git.iotivity.org/iotivity pushd iotivity git fetch --all --tags --prune git checkout tags/1.2.0 -b 1.2.0 git clone https://github.com/01org/tinycbor.git extlibs/tinycbor/tinycbor pushd extlibs/tinycbor/tinycbor/ git checkout tags/v0.3.2 popd echo "Now in " pwd scons resource SECURED=0 TARGET_TRANSPORT=IP echo "Build Completed" export IOTIVITY_DIR=pwd export OCTBSTACK_CFLAGS="-I$IOTIVITY_DIR/resource/csdk/stack/include \ -I$IOTIVITY_DIR/resource/csdk/connectivity/inc/ \ -I$IOTIVITY_DIR/resource/csdk/connectivity/api \ -I$IOTIVITY_DIR/resource/include \ -I$IOTIVITY_DIR/resource/oc_logger/include/\ -I$IOTIVITY_DIR/resource/c_common/oic_string/include/\ -I$IOTIVITY_DIR/resource/c_common/oic_malloc/include/\ -I$IOTIVITY_DIR/resource/c_common/\ -I$IOTIVITY_DIR/resource/c_common/oic_time/include/\ -I$IOTIVITY_DIR/resource/c_common/\ -I$IOTIVITY_DIR/resource/c_common/ocrandom/include/\ -I$IOTIVITY_DIR/extlibs/tinycbor/tinycbor/src\ -I$IOTIVITY_DIR/resource/csdk/stack/include/" export OCTBSTACK_LIBS="-L$IOTIVITY_DIR/out/linux/x86_64/release -loc -loctbstack -lconnectivity_abstraction -loc_logger" echo $IOTIVITY_DIR echo $OCTBSTACK_CFLAGS echo $OCTBSTACK_LIBS popd echo "Now in pwd " npm install

  3. Step 2 went fine.

@gabrielschulhof, please help me set this up.

Forgot to add ROUTING_EP. My bad.
