Bug ID: 30815
Summary: gdbserver prints debug info unconditionally to stderr
Product: gdb
Version: HEAD
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: server
Assignee: unassigned at sourceware dot org
Reporter: gdb-ml at jaeckel dot eu
Target Milestone: ---
Created attachment 15097
--> https://sourceware.org/bugzilla/attachment.cgi?id=15097&action=edit
A WIP patch to approach the issue.
When debugging an ncurses application that is using other background
processes/threads (like e.g. `profanity` https://profanity-im.github.io/),
`gdbserver` prints `Detaching from process XYZ` directly to stderr after
`profanity` started one of those processes.
This leads to the ncurses window being modified and those debug statements
being printed somewhere on the screen.
Reproducing is possible with e.g. profanity.
1. start profanity in gdbserver
```
$ gdbserver localhost:1234 profanity
```
2. connect to said gdbserver instance in another terminal
```
$ gdb -ex "target remote localhost:1234" -ex continue
```
3. connect with profanity to an xmpp server
```
/connect <jid>
```
Now you will see multiple `Detaching from process XYZ` messages throughout the
window.
I've been able to reproduce some artifacts with `irssi` as well, but it's not
that obvious as with `profanity`.
The patchfile that I've attached solves my initial problem, those messages
aren't printed in the debugged window anymore. Still the patch is not complete
as described in the commit message and I didn't want to invest more time before
I've got the OK that this could be an acceptable solution.

Another option might be to send this back to gdb in "O" packets.
However, this won't work with non-stop.
