10 years agoAdd a TRY_CATCH to get_prev_frame_always to better manage errors during unwind.
Andrew Burgess [Wed, 28 May 2014 22:34:43 +0000 (23:34 +0100)]
Add a TRY_CATCH to get_prev_frame_always to better manage errors during unwind.

  https://sourceware.org/ml/gdb-patches/2014-05/msg00737.html

Currently a MEMORY_ERROR raised during unwinding a frame will cause the
unwind to stop with an error message, for example:

  (gdb) bt
  #0  breakpt () at amd64-invalid-stack-middle.c:27
  #1  0x00000000004008f0 in func5 () at amd64-invalid-stack-middle.c:32
  #2  0x0000000000400900 in func4 () at amd64-invalid-stack-middle.c:38
  #3  0x0000000000400910 in func3 () at amd64-invalid-stack-middle.c:44
  #4  0x0000000000400928 in func2 () at amd64-invalid-stack-middle.c:50
  Cannot access memory at address 0x2aaaaaab0000

However, frame #4 is marked as being the end of the stack unwind, so a
subsequent request for the backtrace looses the error message, such as:

  (gdb) bt
  #0  breakpt () at amd64-invalid-stack-middle.c:27
  #1  0x00000000004008f0 in func5 () at amd64-invalid-stack-middle.c:32
  #2  0x0000000000400900 in func4 () at amd64-invalid-stack-middle.c:38
  #3  0x0000000000400910 in func3 () at amd64-invalid-stack-middle.c:44
  #4  0x0000000000400928 in func2 () at amd64-invalid-stack-middle.c:50

When fetching the backtrace, or requesting the stack depth using the MI
interface the situation is even worse, the first time a request is made
we encounter the memory error and so the MI returns an error instead of
the correct result, for example:

  (gdb) -stack-info-depth
  ^error,msg="Cannot access memory at address 0x2aaaaaab0000"

Or,

  (gdb) -stack-list-frames
  ^error,msg="Cannot access memory at address 0x2aaaaaab0000"

However, once one of these commands has been used gdb has, internally,
walked the stack and figured that out that frame #4 is the bottom of the
stack, so the second time an MI command is tried you'll get the "expected"
result:

  (gdb) -stack-info-depth
  ^done,depth="5"

Or,

  (gdb) -stack-list-frames
  ^done,stack=[frame={level="0", .. snip lots .. }]

After this patch the MEMORY_ERROR encountered during the frame unwind is
attached to frame #4 as the stop reason, and is displayed in the CLI each
time the backtrace is requested.  In the MI, catching the error means that
the "expected" result is returned the first time the MI command is issued.
So, from the CLI the results of the backtrace will be:

  (gdb) bt
  #0  breakpt () at amd64-invalid-stack-middle.c:27
  #1  0x00000000004008f0 in func5 () at amd64-invalid-stack-middle.c:32
  #2  0x0000000000400900 in func4 () at amd64-invalid-stack-middle.c:38
  #3  0x0000000000400910 in func3 () at amd64-invalid-stack-middle.c:44
  #4  0x0000000000400928 in func2 () at amd64-invalid-stack-middle.c:50
  Backtrace stopped: Cannot access memory at address 0x2aaaaaab0000

Each and every time that the backtrace is requested, while the MI output
will similarly be consistently:

  (gdb) -stack-info-depth
  ^done,depth="5"

Or,

  (gdb) -stack-list-frames
  ^done,stack=[frame={level="0", .. snip lots .. }]

on GNU/Linux and remote targets (that is, the async-capable targets).

The issue is that when running an infcall, the thread is no longer
marked as running, so run_inferior_call is not calling
wait_for_inferior anymore.

Fix this by doing what the comment actually says we do:

  "Do here what `proceed' itself does in sync mode."

And proceed doesn't check whether the target is running.

I notice this is broken in case of the early return in proceed, but we
were broken before in that case anyway, because run_inferior_call will
think the call actually ran.  Seems like we should make proceed have a
boolean return, and go through all callers making use of it, if
necessary.

But for now, just fix the regression.

10 years agoenable target async by default; separate MI and target notions of async
Pedro Alves [Thu, 29 May 2014 18:58:57 +0000 (19:58 +0100)]
enable target async by default; separate MI and target notions of async

This finally makes background execution commands possible by default.

However, in order to do that, there's one last thing we need to do --
we need to separate the MI and target notions of "async".  Unlike the
CLI, where the user explicitly requests foreground vs background
execution in the execution command itself (c vs c&), MI chose to treat
"set target-async" specially -- setting it changes the default
behavior of execution commands.

So, we can't simply "set target-async" default to on, as that would
affect MI frontends.  Instead we have to make the setting MI-specific,
and teach MI about sync commands on top of an async target.

Because the "target" word in "set target-async" ends up as a potential
source of confusion, the patch adds a "set mi-async" option, and makes
"set target-async" a deprecated alias.

Rather than make the targets always async, this patch introduces a new
"maint set target-async" option so that the GDB developer can control
whether the target is async.  This makes it simpler to debug issues
arising only in the synchronous mode; important because sync mode
seems unlikely to go away.

Unlike in previous revisions, "set target-async" does not affect this
new maint parameter.  The rationale for this is that then one can
easily run the test suite in the "maint set target-async off" mode and
have tests that enable mi-async fail just like they fail on
non-async-capable targets.  This emulation is exactly the point of the
maint option.

I had asked Tom in a previous iteration to split the actual change of
the target async default to a separate patch, but it turns out that
that is quite awkward in this version of the patch, because with MI
async and target async decoupled (unlike in previous versions), if we
don't flip the default at the same time, then just "set target-async
on" alone never actually manages to do anything.  It's best to not
have that transitory state in the tree.

Given "set target-async on" now only has effect for MI, the patch goes
through the testsuite removing it from non-MI tests.  MI tests are
adjusted to use the new and less confusing "mi-async" spelling.

10 years agoMake display_gdb_prompt CLI-only.
Pedro Alves [Fri, 23 May 2014 10:37:12 +0000 (11:37 +0100)]
Make display_gdb_prompt CLI-only.

Enabling target-async by default will require implementing sync
execution on top of an async target, much like foreground command are
implemented on the CLI in async mode.

In order to do that, we will need better control of when to print the
MI prompt.  Currently the interp->display_prompt_p hook is all we
have, and MI just always returns false, meaning, make
display_gdb_prompt a no-op.  We'll need to be able to know to print
the MI prompt in some of the conditions that display_gdb_prompt is
called from the core, but not all.

This is all a litte twisted currently.  As we can see,
display_gdb_prompt is really CLI specific, so make the console
interpreters (console/tui) themselves call it.  To be able to do that,
and add a few different observers that the interpreters can use to
distinguish when or why the the prompt is being printed:

#1 - one called whenever a command is cancelled due to an error.
#2 - another for when a foreground command just finished.

In both cases, CLI wants to print the prompt, while MI doesn't.

MI will want to print the prompt in the second case when in a special
MI mode.

The display_gdb_prompt call in interp_set made me pause.  The comment
there reads:

  /* Finally, put up the new prompt to show that we are indeed here.
     Also, display_gdb_prompt for the console does some readline magic
     which is needed for the console interpreter, at least...  */

But, that looks very much like a no-op to me currently:

 - the MI interpreter always return false in the prompt hook, meaning
   actually display no prompt.

 - the interpreter used at that point is still quiet.  And the
   console/tui interpreters return false in the prompt hook if they're
   quiet, meaning actually display no prompt.

The only remaining possible use would then be the readline magic.  But
whatever that might have been, it's not reacheable today either,
because display_gdb_prompt returns early, before touching readline if
the interpreter returns false in the display_prompt_p hook.

10 years agoPR gdb/13860 - Make MI sync vs async output (closer to) the same.
Pedro Alves [Thu, 29 May 2014 12:09:45 +0000 (13:09 +0100)]
PR gdb/13860 - Make MI sync vs async output (closer to) the same.

Ignoring expected and desired differences like whether the prompt is
output after *stoppped records, GDB MI output is still different in
sync and async modes.

In sync mode, when a CLI execution command is entered, the "reason"
field is missing in the *stopped async record.  And in async mode, for
some events, like program exits, the corresponding CLI output is
missing in the CLI channel.

Vis, diff between sync vs async modes:

   run
   ^running
   *running,thread-id="1"
   (gdb)
   ...
 - ~"[Inferior 1 (process 15882) exited normally]\n"
   =thread-exited,id="1",group-id="i1"
   =thread-group-exited,id="i1",exit-code="0"
 - *stopped
 + *stopped,reason="exited-normally"

   si
   ...
   (gdb)
   ~"0x000000000045e033\t29\t  memset (&args, 0, sizeof args);\n"
 - *stopped,frame=...,thread-id="1",stopped-threads="all",core="0"
 + *stopped,reason="end-stepping-range",frame=...,thread-id="1",stopped-threads="all",core="0"
   (gdb)

In addition, in both cases, when a MI execution command is entered,
and a breakpoint triggers, the event is sent to the console too.  But
some events like program exits have the CLI output missing in the CLI
channel:

   -exec-run
   ^running
   *running,thread-id="1"
   (gdb)
   ...
   =thread-exited,id="1",group-id="i1"
   =thread-group-exited,id="i1",exit-code="0"
 - *stopped
 + *stopped,reason="exited-normally"

We'll want to make background commands always possible by default.
IOW, make target-async be the default.  But, in order to do that,
we'll need to emulate MI sync on top of an async target.  That means
we'll have yet another combination to care for in the testsuite.

Rather than making the testsuite cope with all these differences, I
thought it better to just fix GDB to always have the complete output,
no matter whether it's in sync or async mode.

This is all related to interpreter-exec, and the corresponding uiout
switching.  (Typing a CLI command directly in MI is shorthand for
running it through -interpreter-exec console.)

In sync mode, when a CLI command is active, normal_stop is called when
the current interpreter and uiout are CLI's.  So print_XXX_reason
prints the stop reason to CLI uiout (only), and we don't show it in
MI.

In async mode the stop event is processed when we're back in the MI
interpreter, so the stop reason is printed directly to the MI uiout.

Fix this by making run control event printing roughly independent of
whatever is the current interpreter or uiout.  That is, move these
prints to interpreter observers, that know whether to print or be
quiet, and if printing, which uiout to print to.  In the case of the
console/tui interpreters, only print if the top interpreter.  For MI,
always print.

Breakpoint hits / normal stops are already handled similarly -- MI has
a normal_stop observer that prints the event to both MI and the CLI,
though that could be cleaned up further in the direction of this
patch.

This also makes all of:

 (gdb) foo
and
 (gdb) interpreter-exec MI "-exec-foo"
and
 (gdb)
 -exec-foo
and
 (gdb)
 -interpreter-exec console "foo"

print as expected.

PR gdb/15713 - errors from i386_linux_resume lead to lock-up

linux_nat_resume is not considering that linux_ops->to_resume may throw:

     linux_nat_resume_callback.  */
  lp->stopped = 0;

  if (resume_many)
    iterate_over_lwps (ptid, linux_nat_resume_callback, NULL);

If something within linux_nat_resume_callback throws, GDB leaves the
lwp_info as if the inferior was resumed, while it actually wasn't.

A couple examples, there are possibly others:

 - i386_linux_resume calls target_read which calls QUIT.
 - if the actual ptrace resumption fails in inf_ptrace_resume,
   perror_with_name is called.

If the user tries to kill the inferior at this point (or quit, which
offers to kill), GDB locks up trying to stop the lwp -- if it is
already stopped no new waitpid event gets generated for it.

Fix this by setting the stopped flag earlier, as soon as we collect a
stop event with waitpid, and clearing it always only after resuming
the lwp successfully.

Tested on x86_64 Fedora 20.  Confirmed the lock-up disappears using a
local hack that forces an error in inf_ptrace_resume.

10 years agoPR15693 - Fix spurious *running events, thread state, dprintf-style call
Pedro Alves [Thu, 29 May 2014 11:27:01 +0000 (12:27 +0100)]
PR15693 - Fix spurious *running events, thread state, dprintf-style call

If one sets a breakpoint with a condition that involves calling a
function in the inferior, and then the condition evaluates false, GDB
outputs one *running event for each time the program hits the
breakpoint.  E.g.,

  $ gdb return-false -i=mi

  (gdb)
  start
  ...
  (gdb)
  b 14 if return_false ()
  &"b 14 if return_false ()\n"
  ~"Breakpoint 2 at 0x4004eb: file return-false.c, line 14.\n"
  ...
  ^done
  (gdb)
  c
  &"c\n"
  ~"Continuing.\n"
  ^running
  *running,thread-id=(...)
  (gdb)
  *running,thread-id=(...)
  *running,thread-id=(...)
  *running,thread-id=(...)
  *running,thread-id=(...)
  *running,thread-id=(...)
  ... repeat forever ...

An easy way a user can trip on this is with a dprintf with "set
dprintf-style call".  In that case, a dprintf is just a breakpoint
that when hit GDB calls the printf function in the inferior, and then
resumes it, just like the case above.

If the breakpoint/dprintf is set in a loop, then these spurious events
can potentially slow down a frontend much, if it decides to refresh
its GUI whenever it sees this event (Eclipse is one such case).

When we run an infcall, we pretend we don't actually run the inferior.
This is already handled for the usual case of calling a function
directly from the CLI:

 (gdb)
 p return_false ()
 &"p return_false ()\n"
 ~"$1 = 0"
 ~"\n"
 ^done
 (gdb)

Note no *running, nor *stopped events.  That's handled by:

 static void
 mi_on_resume (ptid_t ptid)
 {
...
   /* Suppress output while calling an inferior function.  */
   if (tp->control.in_infcall)
     return;

and equivalent code on normal_stop.

However, in the cases of the PR, after finishing the infcall there's
one more resume, and mi_on_resume doesn't know that it should suppress
output then too, somehow.

The "running/stopped" state is a high level user/frontend state.
Internal stops are invisible to the frontend.  If follows from that
that we should be setting the thread to running at a higher level
where we still know the set of threads the user _intends_ to resume.

Currently we mark a thread as running from within target_resume, a low
level target operation.  As consequence, today, if we resume a
multi-threaded program while stopped at a breakpoint, we see this:

 -exec-continue
 ^running
 *running,thread-id="1"
 (gdb)
 *running,thread-id="all"

The first *running was GDB stepping over the breakpoint, and the
second is GDB finally resuming everything.

Between those two *running's, threads other than "1" still have their
state set to stopped.  That's bogus -- in async mode, this opens a
tiny window between both resumes where the user might try to run
another execution command to threads other than thread 1, and very
much confuse GDB.

That is, the "step" below should fail the "step", complaining that the
thread is running:

  (gdb) c -a &
  (gdb) thread 2
  (gdb) step

IOW, threads that GDB happens to not resume immediately (say, because
it needs to step over a breakpoint) shall still be marked as running.

Then, if we move marking threads as running to a higher layer,
decoupled from target_resume, plus skip marking threads as running
when running an infcall, the spurious *running events disappear,
because there will be no state transitions at all.

I think we might end up adding a new thread state -- THREAD_INFCALL or
some such, however since infcalls are always synchronous today, I
didn't find a need.  There's no way to execute a CLI/MI command
directly from the prompt if some thread is running an infcall.

Tested on x86_64 Fedora 20.

PR gdb/13860: don't lose '-interpreter-exec console EXECUTION_COMMAND''s output in async mode.

The other part of PR gdb/13860 is about console execution commands in
MI getting their output half lost.  E.g., take the finish command,
executed on a frontend's GDB console:

sync:

  finish
  &"finish\n"
  ~"Run till exit from #0  usleep (useconds=10) at ../sysdeps/unix/sysv/linux/usleep.c:27\n"

  ~"0x00000000004004d7 in foo () at stepinf.c:6\n"
  ~"6\t    usleep (10);\n"
  ~"Value returned is $1 = 0\n"
  *stopped,reason="function-finished",frame={addr="0x00000000004004d7",func="foo",args=[],file="stepinf.c",fullname="/home/pedro/gdb/tests/stepinf.c",line="6"},thread-id="1",stopped-threads="all",core="1"

async:

  finish

Note how all the "Value returned" etc. output is missing in async mode.

The same happens with e.g., catchpoints:

  =breakpoint-modified,bkpt={number="1",type="catchpoint",disp="keep",enabled="y",what="22016",times="1"}
  ~"\nCatchpoint "
  ~"1 (forked process 22016), 0x0000003791cbd8a6 in __libc_fork () at ../nptl/sysdeps/unix/sysv/linux/fork.c:131\n"
  ~"131\t  pid = ARCH_FORK ();\n"
  *stopped,reason="fork",disp="keep",bkptno="1",newpid="22016",frame={addr="0x0000003791cbd8a6",func="__libc_fork",args=[],file="../nptl/sysdeps/unix/sysv/linux/fork.c",fullname="/usr/src/debug/glibc-2.14-394-g8f3b1ff/nptl/sysdeps/unix/sysv/linux/fork.c",line="131"},thread-id="1",stopped-threads="all",core="0"

where all those ~ lines are missing in async mode, or just the "step"
current line indication:

  s
  &"s\n"
  ^running
  *running,thread-id="all"
  (gdb)
  ~"13\t  foo ();\n"
  *stopped,frame={addr="0x00000000004004ef",func="main",args=[{name="argc",value="1"},{name="argv",value="0x7fffffffdd78"}],file="stepinf.c",fullname="/home/pedro/gdb/tests/stepinf.c",line="13"},thread-id="1",stopped-threads="all",core="3"
  (gdb)

Or in the case of the PRs example, the "Stopped due to shared library
event" note:

  start
  &"start\n"
  ~"Temporary breakpoint 1 at 0x400608: file ../../../src/gdb/testsuite/gdb.mi/solib-main.c, line 21.\n"

  ~"Stopped due to shared library event (no libraries added or removed)\n"
  *stopped,reason="solib-event",thread-id="1",stopped-threads="all",core="3"
  (gdb)

IMO, if you're typing execution commands in a frontend's console, you
expect to see their output.  Indeed it's what you get in sync mode.  I
think async mode should do the same.  Deciding what to mirror to the
console wrt to breakpoints and random stops gets messy real fast.
E.g., say "s" trips on a breakpoint.  We'd clearly want to mirror the
event to the console in this case.  But what about more complicated
cases like "s&; thread n; s&", and one of those steps spawning a new
thread, and that thread hitting a breakpoint?  It's impossible in
general to track whether the thread had any relation to the commands
that had been executed.  So I think we should just simplify and always
mirror breakpoints and random events to the console.

Notes:

  - mi->out is the same as gdb_stdout when MI is the current
    interpreter.  I think that referring to that directly is cleaner.
    An earlier revision of this patch made the changes that are now
    done in mi_on_normal_stop directly in infrun.c:normal_stop, and so
    not having an obvious place to put the new uiout by then, and not
    wanting to abuse CLI's uiout, I made a temporary uiout when
    necessary.

  - Hopefuly the rest of the patch is more or less obvious given the
    comments added.

Tested on x86_64 Fedora 20, no regressions.

current sal from the selected frame, overrides the PRINT_WHAT
argument, and only after that does it decide whether to center the
current sal line or not, based on the overridden value, and it will
always decide false.

(The print_stack_frame call in mi_on_normal_stop is a little different
from the call in normal_stop, in that it is an unconditional
SRC_AND_LOC call.  A future patch will make those uniform.)

A previous version of this patch made MI uniform with CLI here, by
making print_stack_frame also center when MI is active.  That changed
the output of a "list" command in mi-cli.exp, to expect line 57
instead of 62, as per the example above.

However, looking deeper, that list in question is the first "list"
after the program stops, and right after the stop, before the "list",
the test did "set listsize 1".  Let's try the same thing with the CLI:

 (gdb) start
 62        callee1 (2, "A string argument.", 3.5);
 (gdb) set listsize 1
 (gdb) list
 57      {

Huh, that's unexpected.  Why the 57?  It's because print_stack_frame,
called in reaction to the breakpoint stop, expecting the next "list"
to show 10 lines (the listsize at the time) around line 62, sets the
lines listed range to 57-67 (62 +/- 5).  If the user changes the
listsize before "list", why would we still show that range?  Looks
bogus to me.

So the fix for this whole issue should be delay trying to center the
listing to until actually listing, so that the correct listsize can be
taken into account.  This makes MI and CLI uniform too, as it deletes
the center code from print_stack_frame.

A series of tests are added to list.exp to cover this.  mi-cli.exp was
after all correct all along, but it now gains an additional test that
lists lines with listsize 10, to ensure the centering is consistent
with CLI's.

One related Python test changed related output -- it's a test that
prints the line number after stopping for a breakpoint, similar to the
new list.exp tests.  Previously we'd print the stop line minus 5 (due
to the premature centering), now we print the stop line.  I think
that's a good change.

Tested on x86_64 Fedora 20.

10 years agoAllow making GDB not automatically connect to the native target.
Pedro Alves [Wed, 21 May 2014 17:30:47 +0000 (18:30 +0100)]
Allow making GDB not automatically connect to the native target.

Sometimes it's useful to be able to disable the automatic connection
to the native target.  E.g., sometimes GDB disconnects from the
extended-remote target I was debugging, without me noticing it, and
then I do "run".  That starts the program locally, and only after a
little head scratch session do I figure out the program is running
locally instead of remotely as intended.  Same thing with "attach",
"info os", etc.

With the patch, we now can have this instead:

 (gdb) set auto-connect-native-target off
 (gdb) target extended-remote :9999
 ...
 *gdb disconnects*
 (gdb) run
 Don't know how to run.  Try "help target".

To still be able to connect to the native target with
auto-connect-native-target set to off, I've made "target native" work
instead of erroring out as today.

Before:

 (gdb) target native
 Use the "run" command to start a native process.

After:

 (gdb) target native
 Done.  Use the "run" command to start a process.
 (gdb) maint print target-stack
 The current target stack is:
   - native (Native process)
   - exec (Local exec file)
   - None (None)
 (gdb) run
 Starting program: ./a.out
 ...

I've also wanted this for the testsuite, when running against the
native-extended-gdbserver.exp board (runs against gdbserver in
extended-remote mode).  With a non-native-target board, it's always a
bug to launch a program with the native target.  Turns out we still
have one such case this patch catches:

 (gdb) break main
 Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138.
 (gdb) run
 Don't know how to run.  Try "help target".
 (gdb) FAIL: gdb.base/corefile.exp: run: with core

On the patch itself, probably the least obvious bit is the need to go
through all targets, and move the unpush_target call to after the
generic_mourn_inferior call instead of before.  This is what
inf-ptrace.c does too, ever since multi-process support was added.
The reason inf-ptrace.c does things in that order is that in the
current multi-process/single-target model, we shouldn't unpush the
target if there are still other live inferiors being debugged.  The
check for that is "have_inferiors ()" (a misnomer nowadays...), which
does:

 have_inferiors (void)
 {
   for (inf = inferior_list; inf; inf = inf->next)
     if (inf->pid != 0)
       return 1;

It's generic_mourn_inferior that ends up clearing inf->pid, so we need
to call it before the have_inferiors check.  To make all native
targets behave the same WRT to explicit "target native", I've added an
inf_child_maybe_unpush_target function that targets call instead of
calling unpush_target directly, and as that includes the
have_inferiors check, I needed to adjust the targets.

Tested on x86_64 Fedora 20, native, and also with the
extended-gdbserver board.

Confirmed a cross build of djgpp gdb still builds.

Smoke tested a cross build of Windows gdb under Wine.

Untested otherwise.

the native target" anyway.  I was worrying a little that "native"
might be a lie too if some port comes up with a default target that
can run but is not really native, but I think that's a very minor
issue - we can consider that "native" really means the default built
in target that GDB supports, instead of saying that's the target that
debugs host native processes, if it turns out necessary.

This change doesn't affect users much, because "target child" results
in error today:

 (gdb) target child
 Use the "run" command to start a child process.

Other places "child" is visible:

 (gdb) help target
 ...
 List of target subcommands:

 target child -- Child process (started by the "run" command)
 target core -- Use a core file as a target
 target exec -- Use an executable file as a target

These places will say "native" instead.  I think that's a good thing.
