Problem to connect to shvspy #288

Closed robertobucher closed 1 year ago

robertobucher commented 1 year ago

Since a couple of weeks, I can't connect from my generated pysimCoder application to the window of shvspy.

The generated code starts correctly:

bucher@debian:~/ToDo/testSHV$ ./testSHV Socket successfully created. Connected to the server.

but when I try to open the server on the shvspy, I get:

Segmentation fault

This happen with an old version of shvapp/shvspy and with the new versions of these applications. Thus, I think that the problem can be related to the new version of libshv.

ShvSpy is connecting to shvbroker, please can you send shvbroker log and shvspy log as well.

Attached the output on the shell. The log window on the brooker is empty

fvacek commented 1 year ago

I cannot see any segfault in logs attached. Do you mean segfault shvspy after RPC request timeout expired for node: test/untitled? I need some clue, how to reproduce this issue.

robertobucher commented 1 year ago

As soon as I open the "test" tree to get the child "untitled", the applications compiled with libshv goes in "Segmentation fault"

The application testSHV starts correctly, and gives the following output:

Socket successfully created. Connected to the server.

But at the moment that I open the tree, I receive a "Segmentation faul". The two apps "shvbroker" and "ahvspy" continue to work without any message...

If I understand correctly, it is your testing app, which is seg-faulting? Can you run it in debugger and send me stack trace?

robertobucher commented 1 year ago

Sorry for delay! I've finally found some time to do a debug of the code.

This is the output:

On monday I'll try to find out more info

This is the full stack when I enter in the procedure that gives the causes the "segmentation fault":

fvacek commented 1 year ago

I'm afraid that we cannot fix bugs in your testing code, only bugs in our code. If your testing app can be easily build on my box, I can try to reproduce seg-fault on my own.

michallenc commented 1 year ago

@robertobucher Just an idea: do you have subsystems in your block diagram? I personally have never tested them with SHV so it may be possible that some error occurs there (most likely in naming).

robertobucher commented 1 year ago

Not in my examples that didn't work...

I've isolated the function that creates the segfault, but I can't understand why!

Ciao

The problem is in the files pysimCoder/CodeGen/Common/shv, in particular the file "shv_tree.c": there is a call (line 353) to

 const shv_method_des_t *met_des = shv_dmap_find(item->dir, &met);

and this call causes the "segmentation fault".

I can't find this function: the debugger point to this line in include/shv_tree.h

GSA_CUST_DEC(shv_dmap, shv_dmap_t, shv_method_des_t, shv_method_des_key_t,     methods, name, shv_method_des_comp_func)

and from here I can't continue to debug the application...

robertobucher commented 1 year ago

I probably found the problem. By compiling the devices in pysimCoder (for example for LinuxRT) with SHV=1, the system doesn't find the file

pack_double.c

which is in the folder "proof_of_concept-code" under libshv/libshvchainpack/c/

Moving this file under libshv/libshvchainpack/c/ solves the problem.

Probably we have to modify the Makefiles for the devices that uses SHV

fvacek commented 1 year ago

Yes, pack_double.c is not used in libshv, thus it was removed from build, please update also your Makefile.

robertobucher commented 1 year ago

Thanks. I've eliminated the pack_double,c file in the compilation and all is working perfect again!
