I have started seeing occasional runaway 'attach' processes these days.
|
|
I cannot be certain it is really caused by this patch, for example
|
|
grep 'FAIL.*cmdline attach run' does not show anything in my logs.
|
|
|
|
But as I remember this 'attach' runaway process always happened in GDB (but
|
|
I do not remember it in the past months) I think it would be most safe to just
|
|
solve it forever by [attached].

* gdb.base/attach.c: Include unistd.h.
|
|
(main): Call alarm. Add label postloop.
|
|
* gdb.base/attach.exp (do_attach_tests): Use gdb_get_line_number,
|
|
gdb_breakpoint, gdb_continue_to_breakpoint.
|
|
(test_command_line_attach_run): Kill ${testpid} in one exit path.
