ehamine / abus Goto Github PK

What is the expected output? What do you see instead?

I was surprise to be able to export the same services two times without any 
error.

I think the second should generate an error message.

What do you think about ?

Hi,

After an error from my side, i have exported a complete object (data struct), 
item by item.

However, the abus_init() was call just after so the context was initialized 
after and the export was incorrect.

Then, i have placed the abus_init() before the object export and it was correct 
afterwards.

So, is it possible to add a check in all abus function that verify if whether 
or not the abus initialization have been done when an abus call is done 
(boolean lock, mutex, magic number, ...)

Hi,

While i am trying a global introspection, i have a crash by the process that 
have the abus service.

The client command just display :

$ abus-send -v DmngCoreStub.\*

## 11854 -> tmp/abus/DmngCoreStub:62 
{"jsonrpc":"2.0","method":"DmngCoreStub.*","id":0,"params":{}}

... and nothing else.

On the server side the crash provide the following trace :

## 32286 <- 00f2c:62 
{"jsonrpc":"2.0","method":"DmngCoreStub.*","id":0,"params":{}}

It seems that's appears when there are lot of RPC methods, so a huge response 
message.
