Waiting for events in sync mode
|
|
|
|
|
===============================
|
|
|
|
|
|
|
|
|
|
When waiting for an event in a specific thread, we just use waitpid, passing
|
|
|
|
|
the specific pid, and not passing WNOHANG.
|
|
|
|
|
|
|
|
|
|
When waiting for an event in all threads, waitpid is not quite good. Prior to
|
|
|
|
|
version 2.4, Linux can either wait for event in main thread, or in secondary
|
|
|
|
|
threads. (2.4 has the __WALL flag). So, if we use blocking waitpid, we might
|
|
|
|
|
miss an event. The solution is to use non-blocking waitpid, together with
|
|
|
|
|
sigsuspend. First, we use non-blocking waitpid to get an event in the main
|
|
|
|
|
process, if any. Second, we use non-blocking waitpid with the __WCLONED
|
|
|
|
|
flag to check for events in cloned processes. If nothing is found, we use
|
|
|
|
|
sigsuspend to wait for SIGCHLD. When SIGCHLD arrives, it means something
|
|
|
|
|
happened to a child process -- and SIGCHLD will be delivered both for events
|
|
|
|
|
in main debugged process and in cloned processes. As soon as we know there's
|
|
|
|
|
an event, we get back to calling nonblocking waitpid with and without __WCLONED.
|
|
|
|
|
|
|
|
|
|
Note that SIGCHLD should be blocked between waitpid and sigsuspend calls,
|
|
|
|
|
so that we don't miss a signal. If SIGCHLD arrives in between, when it's
|
|
|
|
|
blocked, the signal becomes pending and sigsuspend immediately
|
|
|
|
|
notices it and returns.
|
|
|
|
|
|
|
|
|
|
Waiting for events in async mode
|
|
|
|
|
================================
|
|
|
|
|
|
|
|
|
|
In async mode, GDB should always be ready to handle both user input and target
|
|
|
|
|
events, so neither blocking waitpid nor sigsuspend are viable
|
|
|
|
|
options. Instead, we should notify the GDB main event loop whenever there's
|
|
|
|
|
unprocessed event from the target. The only way to notify this event loop is
|
|
|
|
|
to make it wait on input from a pipe, and write something to the pipe whenever
|
|
|
|
|
there's event. Obviously, if we fail to notify the event loop if there's
|
|
|
|
|
target event, it's bad. If we notify the event loop when there's no event
|
|
|
|
|
from target, linux-nat.c will detect that there's no event, actually, and
|
|
|
|
|
report event of type TARGET_WAITKIND_IGNORE, but it will waste time and
|
|
|
|
|
better avoided.
|
|
|
|
|
|
|
|
|
|
The main design point is that every time GDB is outside linux-nat.c, we have a
|
|
|
|
|
SIGCHLD handler installed that is called when something happens to the target
|
|
|
|
|
and notifies the GDB event loop. Also, the event is extracted from the target
|
|
|
|
|
using waitpid and stored for future use. Whenever GDB core decides to handle
|
|
|
|
|
the event, and calls into linux-nat.c, we disable SIGCHLD and process things
|
|
|
|
|
as in sync mode, except that before waitpid call we check if there are any
|
|
|
|
|
previously read events.
|
|
|
|
|
|
|
|
|
|
It could happen that during event processing, we'll try to get more events
|
|
|
|
|
than there are events in the local queue, which will result to waitpid call.
|
|
|
|
|
Those waitpid calls, while blocking, are guarantied to always have
|
|
|
|
|
something for waitpid to return. E.g., stopping a thread with SIGSTOP, and
|
|
|
|
|
waiting for the lwp to stop.
|
|
|
|
|
|
|
|
|
|
The event loop is notified about new events using a pipe. SIGCHLD handler does
|
|
|
|
|
waitpid and writes the results in to a pipe. GDB event loop has the other end
|
|
|
|
|
of the pipe among the sources. When event loop starts to process the event
|
|
|
|
|
and calls a function in linux-nat.c, all events from the pipe are transferred
|
|
|
|
|
into a local queue and SIGCHLD is blocked. Further processing goes as in sync
|
|
|
|
|
mode. Before we return from linux_nat_wait, we transfer all unprocessed events
|
|
|
|
|
from local queue back to the pipe, so that when we get back to event loop,
|
|
|
|
|
event loop will notice there's something more to do.
|
|
|
|
|
|
|
|
|
|
SIGCHLD is blocked when we're inside target_wait, so that should we actually
|
|
|
|
|
want to wait for some more events, SIGCHLD handler does not steal them from
|
|
|
|
|
us. Technically, it would be possible to add new events to the local queue but
|
|
|
|
|
it's about the same amount of work as blocking SIGCHLD.
|
|
|
|
|
|
|
|
|
|
This moving of events from pipe into local queue and back into pipe when we
|
|
|
|
|
enter/leave linux-nat.c is somewhat ugly. Unfortunately, GDB event loop is
|
|
|
|
|
home-grown and incapable to wait on any queue.
|
|
|
|
|
|
|
|
|
|
Use of signals
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
We stop threads by sending a SIGSTOP. The use of SIGSTOP instead of another
|
|
|
|
|
signal is not entirely significant; we just need for a signal to be delivered,
|
|
|
|
|
so that we can intercept it. SIGSTOP's advantage is that it can not be
|
|
|
|
|
blocked. A disadvantage is that it is not a real-time signal, so it can only
|
|
|
|
|
be queued once; we do not keep track of other sources of SIGSTOP.
|
|
|
|
|
|
|
|
|
|
Two other signals that can't be blocked are SIGCONT and SIGKILL. But we can't
|
|
|
|
|
use them, because they have special behavior when the signal is generated -
|
|
|
|
|
not when it is delivered. SIGCONT resumes the entire thread group and SIGKILL
|
|
|
|
|
kills the entire thread group.
|
|
|
|
|
|
|
|
|
|
A delivered SIGSTOP would stop the entire thread group, not just the thread we
|
|
|
|
|
tkill'd. But we never let the SIGSTOP be delivered; we always intercept and
|
|
|
|
|
cancel it (by PTRACE_CONT without passing SIGSTOP).
|
|
|
|
|
|
|
|
|
|
We could use a real-time signal instead. This would solve those problems; we
|
|
|
|
|
could use PTRACE_GETSIGINFO to locate the specific stop signals sent by GDB.
|
|
|
|
|
But we would still have to have some support for SIGSTOP, since PTRACE_ATTACH
|
|
|
|
|
generates it, and there are races with trying to find a signal that is not
|
|
|
|
|
blocked. */

/* Determine if PTRACE_O_TRACEFORK can be used to follow fork events.

|
|
First, we try to enable fork tracing on ORIGINAL_PID. If this fails,
|
|
|
|
|
we know that the feature is not available. This may change the tracing
|
|
|
|
|
options for ORIGINAL_PID, but we'll be setting them shortly anyway.
|
|
|
|
|
|
|
|
|
|
However, if it succeeds, we don't know for sure that the feature is
|
|
|
|
|
available; old versions of PTRACE_SETOPTIONS ignored unknown options. We
|
2003-06-15 22:56:48 +02:00
|
|
|
|
create a child process, attach to it, use PTRACE_SETOPTIONS to enable
|
2004-11-21 21:10:02 +01:00
|
|
|
|
fork tracing, and let it fork. If the process exits, we assume that we
|
|
|
|
|
can't use TRACEFORK; if we get the fork notification, and we can extract
|
|
|
|
|
the new child's PID, then we assume that we can. */

/* We can't insert breakpoints until the child has

|
|
|
finished with the shared memory region. We need to
|
|
|
|
|
wait until that happens. Ideal would be to just
|
|
|
|
|
call:
|
|
|
|
|
- ptrace (PTRACE_SYSCALL, parent_pid, 0, 0);
|
|
|
|
|
- waitpid (parent_pid, &status, __WALL);
|
|
|
|
|
However, most architectures can't handle a syscall
|
|
|
|
|
being traced on the way out if it wasn't traced on
|
|
|
|
|
the way in.
|
|
|
|
|
|
|
|
|
|
We might also think to loop, continuing the child
|
|
|
|
|
until it exits or gets a SIGTRAP. One problem is
|
|
|
|
|
that the child might call ptrace with PTRACE_TRACEME.
|
|
|
|
|
|
|
|
|
|
There's no simple and reliable way to figure out when
|
|
|
|
|
the vforked child will be done with its copy of the
|
|
|
|
|
shared memory. We could step it out of the syscall,
|
|
|
|
|
two instructions, let it go, and then single-step the
|
|
|
|
|
parent once. When we have hardware single-step, this
|
|
|
|
|
would work; with software single-step it could still
|
|
|
|
|
be made to work but we'd have to be able to insert
|
|
|
|
|
single-step breakpoints in the child, and we'd have
|
|
|
|
|
to insert -just- the single-step breakpoint in the
|
|
|
|
|
parent. Very awkward.
|
|
|
|
|
|
|
|
|
|
In the end, the best we can do is to make sure it
|
|
|
|
|
runs for a little while. Hopefully it will be out of
|
|
|
|
|
range of any breakpoints we reinsert. Usually this
|
|
|
|
|
is only the single-step breakpoint at vfork's return
|
|
|
|
|
point. */

/* On GNU/Linux there are no real LWP's. The closest thing to LWP's
|
|
|
|
|
are processes sharing the same VM space. A multi-threaded process
|
|
|
|
|
is basically a group of such processes. However, such a grouping
|
|
|
|
|
is almost entirely a user-space issue; the kernel doesn't enforce
|
|
|
|
|
such a grouping at all (this might change in the future). In
|
|
|
|
|
general, we'll rely on the threads library (i.e. the GNU/Linux
|
|
|
|
|
Threads library) to provide such a grouping.
|
|
|
|
|
|
|
|
|
|
It is perfectly well possible to write a multi-threaded application
|
|
|
|
|
without the assistance of a threads library, by using the clone
|
|
|
|
|
system call directly. This module should be able to give some
|
|
|
|
|
rudimentary support for debugging such applications if developers
|
|
|
|
|
specify the CLONE_PTRACE flag in the clone system call, and are
|
|
|
|
|
using the Linux kernel 2.4 or above.
|
|
|
|
|
|
|
|
|
|
Note that there are some peculiarities in GNU/Linux that affect
|
|
|
|
|
this code:
|
|
|
|
|
|
|
|
|
|
- In general one should specify the __WCLONE flag to waitpid in
|
|
|
|
|
order to make it report events for any of the cloned processes
|
|
|
|
|
(and leave it out for the initial process). However, if a cloned
|
|
|
|
|
process has exited the exit status is only reported if the
|
|
|
|
|
__WCLONE flag is absent. Linux kernel 2.4 has a __WALL flag, but
|
|
|
|
|
we cannot use it since GDB must work on older systems too.
|
|
|
|
|
|
|
|
|
|
- When a traced, cloned process exits and is waited for by the
|
|
|
|
|
debugger, the kernel reassigns it to the original parent and
|
|
|
|
|
keeps it around as a "zombie". Somehow, the GNU/Linux Threads
|
|
|
|
|
library doesn't notice this, which leads to the "zombie problem":
|
|
|
|
|
When debugged a multi-threaded process that spawns a lot of
|
|
|
|
|
threads will run out of processes, even if the threads exit,
|
|
|
|
|
because the "zombies" stay around. */
