            Bug ID: 26221
           Summary: "Interrupted system call" when resizing terminal while
                    GDB is waiting for remote connection
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: remote
          Assignee: unassigned at sourceware dot org
          Reporter: simark at simark dot ca
  Target Milestone: ---

Type "target remote :1234" in GDB, while nothing is listening on port 1234. 
GDB waits for the connection to be established.  Meanwhile, resize the
terminal.  This happens:

(gdb) tar rem :1234
:1234: Interrupted system call.

Looks like we don't handle and restart interrupted system call somewhere where
we should.

--- Comment #1 from Tom Tromey <tromey at sourceware dot org> ---
I couldn't reproduce this on x86-64 Fedora 34.
I tried both with and without the TUI.

Only the TUI installs SIGWINCH and nowadays it uses SA_RESTART.
So maybe this is fixed?  The thing is, though, I think the
SA_RESTART code dates from 2014... maybe there was another
SIGWINCH handler in the past?
