gdbserver for threaded application

gdbserver for threaded application

[Laurent Morichetti]

Hi,

Which gdbserver should I use to remote debug a threaded application on
linux? The one I have does not seem to understand the thread queries.

I am not sure about what kind of support you want to thread queries for
gdbserver.

I made the gdb stub used in x86 linux kernel ( for kernel debugging ) und=
erstand
thread queries sometime back.

Sorry!
I was going to send this mail later but accidentaly sent it without compl=
eting.
I was thinking about feasibility of implementing it.

OK. I looked at gdbserver code, there are number of differences in how a =
user
level gdb stub accesses a thread compared to a kernel level gdb stub. The=
 stub
I have handles thread queries easily because any thread is directly acces=
sible
inside the kernel. gdbserver will have to intercept all clone calls and k=
eep
track of threads.

I plan to implement it this weekend.
