Subject: [patch] Suggest running gdbserver for a PID in container

Hi,
|
||
|
|
|
||
|
|
currently
|
||
|
|
gdb -p <pid from a container>
|
||
|
|
will print:
|
||
|
|
warning: Target and debugger are in different PID namespaces; thread lists and other data are likely unreliable
|
||
|
|
|
||
|
|
BTW it is a bit lost in all the other messages. Full screen output is in:
|
||
|
|
https://sourceware.org/bugzilla/show_bug.cgi?id=19828
|
||
|
|
|
||
|
|
It correctly states the problem but it does not say how to solve it.
|
||
|
|
|
||
|
|
Is at least this little suggestion OK?
|
||
|
|
|
||
|
|
Originally I wanted to suggest also the Docker "-p 1234:1234" parameter but
|
||
|
|
I see the containers are more general topic than just Docker (even LxC etc.).
|
||
|
|
|
||
|
|
According to Gary future GDBs should be able to work even without gdbserver.
|
||
|
|
But currently gdbserver is still required.
|
||
|
|
|
||
|
|
|
||
|
|
Thanks,
|
||
|
