With multi-target, each inferior now has its own target connection.
The problem in switch_to_program_space_and_thread is that in the
current state GDB switches to "no thread" and also sets the program
space but because the inferior is not switched, potentially an
incorrect target remains selected.
Here is a sample scenario that exploits this flow:
On terminal 1, start a gdbserver on a program named foo:
$ gdbserver :1234 ./foo
On terminal 2, start gdb on a program named bar. Suppose foo and bar
are compiled from foo.c and bar.c. They are completely separate. So,
bar.c:2 has no meaning for foo.
$ gdb -q ./bar
Reading symbols from ./bar...
(gdb) add-inferior
[New inferior 2]
Added inferior 2
(gdb) inferior 2
[Switching to inferior 2 [<null>] (<noexec>)]
(gdb) target remote :1234
...
(gdb) set debug remote 2
(gdb) break bar.c:2
Sending packet: $Hgp0.0#ad...Packet received: OK
Sending packet: $m5fa,12#f8...Packet received: E01
Sending packet: $m5fa,1#c6...Packet received: E01
Sending packet: $m5fb,3#c9...Packet received: E01
Sending packet: $m5fe,1#ca...Packet received: E01
Breakpoint 1 at 0x5fe: file bar.c, line 2.
(gdb)
Here we have an unnecessary sending of the packets to the gdbserver.
With this fix in progspace-and-thread.c, we'll get this:
(gdb) break bar.c:2
Breakpoint 1 at 0x5fe: file bar.c, line 2.
(gdb)
Now there is no sending of the packets to gdbserver.
The changes around clear_symtab_users calls are necessary because
otherwise we regress gdb.base/step-over-exit.exp, hitting the new
assertion in switch_to_program_space_and_thread. The problem is, a
forked child terminates, and when GDB decides to auto-purge that
inferior, GDB tries to switch to the pspace of that no-longer-existing
inferior.
The root of the problem is within the program_space destructor:
program_space::~program_space ()
{
...
set_current_program_space (this); # (1)
...
breakpoint_program_space_exit (this); # (2)
...
free_all_objfiles (); # (3)
...
}
We get here from delete_inferior -> delete_program_space.
So we're deleting an inferior, and the inferior to be
deleted is no longer in the inferior list.
At (2), we've deleted all the breakpoints and locations for the
program space being deleted.
The crash happens while doing a breakpoint re-set, called by
clear_symtab_users at the tail end of (3). That is, while recreating
breakpoints for the current program space, which is the program space
we're tearing down. During breakpoint re-set, we try to switch to the
new location's pspace (the current pspace set in (1), so the pspace
we're tearing down) with switch_to_program_space_and_thread, and that
hits the failed assertion. It's the fact that we recreate breakpoints
in the program_space destructor that is the latent bug here. Just
don't do that, and we don't end up in the crash situation.
My first approach to fix this added a symfile_add_flags parameter to
program_space::free_all_objfiles, and then passed that down to
clear_symtab_users. The program_space dtor would then pass down
SYMFILE_DEFER_BP_RESET to free_all_objfiles. I couldn't help feeling
that adding that parameter to free_all_objfiles looked a little
awkward, so I settled on something a little different -- hoist the
clear_symtab_users call to the callers. There are only two callers.
I felt that that didn't look as odd, particularly since
remove_symbol_file_command also does:
objf->unlink ();
clear_symtab_users (0);
I.e., objfile deletion is already separate from calling
clear_symtab_users in some places.

This changes objfiles to be managed using a shared_ptr. shared_ptr is
chosen because it enables the use of objfiles in background threads.
The simplest way to do this was to introduce a new iterator that will
return the underlying objfile, rather than a shared_ptr. (I also
tried changing the rest of gdb to use shared_ptr, but this was quite
large; and to using intrusive reference counting, but this also was
tricky.)

This introduces a new method, program_space::remove_objfile, and
changes the objfile destructor not to unlink an objfile from the
program space's list.
This is cleaner because, like the previous patch, it treats the
program space more like a container for objfiles. Also, this makes it
possible to keep an objfile alive even though it has been unlinked
from the program space's list, which is important for processing in a
worker thread.

This introduces a new method, program_space::add_objfile, that adds an
objfile to the program space's list of objfiles. It also changes the
obfile's constructor so that linking an objfile into this list is not
done here.
The former is an improvement because it makes more sense to treat the
program space as a container holding objfiles -- so manipulation of
the list belongs there.
The latter is not strictly needed, but seemed better both because it
is removing a global side effect from a constructor, and for symmetry
reasons, as a subsequent patch will remove unlinking from the
destructor.

Currently the target pid_to_str method returns a const char *, so many
implementations have a static buffer that they update. This patch
changes these methods to return a std::string instead. I think this
is cleaner and avoids possible gotchas when calling pid_to_str on
different ptids in a single statement. (Though no such calls exist
currently.)
This also updates various helper functions, and the gdbarch pid_to_str
methods.
I also made a best effort to fix all the callers, but I can't build
some of the *-nat.c files.

This is more preparation bits for multi-target support.
In a multi-target scenario, we need to address the case of different
processes/threads running on different targets that happen to have the
same PID/PTID. E.g., we can have both process 123 in target 1, and
process 123 in target 2, while they're in reality different processes
running on different machines. Or maybe we've loaded multiple
instances of the same core file. Etc.
To address this, in my WIP multi-target branch, threads and processes
are uniquely identified by the (process_stratum target_ops *, ptid_t)
and (process_stratum target_ops *, pid) tuples respectively. I.e.,
each process_stratum instance has its own thread/process number space.
As you can imagine, that requires passing around target_ops * pointers
in a number of functions where we're currently passing only a ptid_t
or an int. E.g., when we look up a thread_info object by ptid_t in
find_thread_ptid, the ptid_t alone isn't sufficient.
In many cases though, we already have the thread_info or inferior
pointer handy, but we "lose" it somewhere along the call stack, only
to look it up again by ptid_t/pid. Since thread_info or inferior
objects know their parent target, if we pass around thread_info or
inferior pointers when possible, we avoid having to add extra
target_ops parameters to many functions, and also, we eliminate a
number of by ptid_t/int lookups.
So that's what this patch does. In a bit more detail:
- Changes a number of functions and methods to take a thread_info or
inferior pointer instead of a ptid_t or int parameter.
- Changes a number of structure fields from ptid_t/int to inferior or
thread_info pointers.
- Uses the inferior_thread() function whenever possible instead of
inferior_ptid.
- Uses thread_info pointers directly when possible instead of the
is_running/is_stopped etc. routines that require a lookup.
- A number of functions are eliminated along the way, such as:
int valid_gdb_inferior_id (int num);
int pid_to_gdb_inferior_id (int pid);
int gdb_inferior_id_to_pid (int num);
int in_inferior_list (int pid);
- A few structures and places hold a thread_info pointer across
inferior execution, so now they take a strong reference to the
(refcounted) thread_info object to avoid the thread_info pointer
getting stale. This is done in enable_thread_stack_temporaries and
in the infcall.c code.
- Related, there's a spot in infcall.c where using a RAII object to
handle the refcount would be handy, so a gdb::ref_ptr specialization
for thread_info is added (thread_info_ref, in gdbthread.h), along
with a gdb_ref_ptr policy that works for all refcounted_object types
(in common/refcounted-object.h).

Using this simple test:
static void
break_here ()
{
}
int
main (int argc, char *argv[])
{
fork ();
break_here();
return 0;
}
compiled as a PIE:
$ gcc test.c -g3 -O0 -o test -pie
and running this:
$ ./gdb -nx -q --data-directory=data-directory ./test -ex "b break_here" -ex "set detach-on-fork off" -ex r
gives:
Warning:
Cannot insert breakpoint 1.
Cannot access memory at address 0x64a
Note that GDB might get stopped by SIGTTOU because of this issue:
https://sourceware.org/bugzilla/show_bug.cgi?id=23020
In that case, just use "fg" to continue.
This issue happens only with position-independent executables. Adding
the main objfile for the new inferior (the fork child) causes GDB to try
to reset the breakpoints. However, that new objfile has not been
relocated yet. So the breakpoint on "break_here" resolves to an
unrelocated address, from which we are trying to read/write to set a
breakpoint. Passing SYMFILE_DEFER_BP_RESET avoids that problem. The
executable is relocated just after, in the follow_fork_inferior
function.
The buildbot seems happy with this patch. I don't think it's necessary
to add a new test. Just changing this made many tests go from FAIL to
PASS on my machine, where gcc produces PIE executables by default. If
anything, I think we would need to add a board file that produces
position-independent executables, so that we can run all the tests with
PIE, even on machines where that is not the default.

A following patch will remove this hack from within regcache's
implementation:
struct regcache *
get_thread_arch_regcache (ptid_t ptid, struct gdbarch *gdbarch)
{
struct address_space *aspace;
/* For the benefit of "maint print registers" & co when debugging an
executable, allow dumping the regcache even when there is no
thread selected (target_thread_address_space internal-errors if
no address space is found). Note that normal user commands will
fail higher up on the call stack due to no
target_has_registers. */
aspace = (ptid_equal (null_ptid, ptid)
? NULL
: target_thread_address_space (ptid));
i.e., it'll no longer be possible to try to build a regcache for
null_ptid. That change alone would regress the gdbarch self tests
though, causing this:
(gdb) maintenance selftest
[...]
Running selftest register_to_value.
src/gdb/inferior.c:309: internal-error: inferior* find_inferior_pid(int): Assertion `pid != 0' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.gdb/unittest.exp: maintenance selftest (GDB internal error)
The problem is that the way the mocking environment for those unit
tests is written is a bit fragile: it creates a special purpose
regcache (and sentinel's frame), using whatever is the current
inferior_ptid (usually null_ptid), and assumes get_current_regcache
will find that in the regcache::current_regcache list.
This commit changes the way the mock environment is created. It
eliminates the special regcache and frame and instead creates a fuller
mock environment, with a custom mock target_ops, and then a mock
inferior and thread "running" on that target.
If there's already a running target when you type "maint selftest",
then we error out, instead of pushing a new target on top of the
existing one (and thus killing the debug session). This results in:
(gdb) maint selftest
(...)
Self test failed: arch i386: target already pushed

Self test failed: self-test failed at /home/pedro/gdb/mygit/src/gdb/selftest-arch.c:86
(...)

I think that's OK, because self tests are really meant to be run from
a clean state right after GDB is started. I'm adding that erroring
out just as safe measure just in case someone types "maint selftest"
on the command line while already debugging something (as I've done
it).
(In my multi-target branch, where this patch originated from, we don't
actually need to error out, because there each inferior has its own
target stack).
Also, note that the current code was doing:
current_inferior()->gdbarch = gdbarch;
without taking care to restore the previous gdbarch. This means that
GDB's state was being left inconsistent after running the self tests,
further supporting the point that there's probably not much
expectation that mixing "maint selftests" and regular debugging in the
same GDB invocation really works. This patch fixes that, regardless.

After all the make_cleanup_restore_current_thread fixing, I thought
I'd convert that and its relatives (which are all cleanups) to RAII

This patch changes various places to use ui_out_emit_tuple,
eliminating a number of cleanups. This patch only tackles "easy"
cases, which are ones where the cleanups in question were
block-structured and did not involve any changes other than the
obvious replacement.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.

This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy. ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.
In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.
It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

gdb/ChangeLog:
* progspace.c (delete_program_space): Add missing spaces.
|

When deleting an inferior, delete the associated program space as well
if it becomes unused. This replaces the "pruning" approach, with which
you could forget to call prune_program_spaces (as seen, with the
-remove-inferior command, see [1]).
This allows to remove the prune_program_spaces function. At the same
time, I was able to clean up the delete_inferior* family:
- delete_inferior is unused
- delete_inferior_silent is only used in monitor_close, but is replaced
with discard_all_inferiors [2], so it becomes unused
- All remaining calls to delete_inferior_1 are with silent=1, so the
parameter is removed
- delete_inferior_1 is renamed to delete_inferior
I renamed pspace_empty_p to program_space_empty_p. I prefer if the
"exported" functions have a more explicit and standard name.
Tested on Ubuntu 14.10.

Reverted, since it causes a build failure. It turns out that
delete_inferior_silent wasn't actually unused.
This reverts commit 0560c645c02eba2828a053039dcfdf676cdd1d00.

This allows to remove the prune_program_spaces function. At the same

delete_inferior_silent and delete_inferior were unused, which allowed
renaming delete_inferior_1 to delete_inferior. Also, since all calls to
it were with silent=1, I removed that parameter completely.
I renamed pspace_empty_p to program_space_empty_p. I prefer if the
"exported" functions have a more explicit and standard name.

A patch I wrote made GDB pull the thread list sooner when debugging
with target remote, and I noticed an intended consequence. GDB
started bouncing around the currently selected remote/general thread
more frequently. E.g.:
Sending packet: $qTMinFTPILen#3b...Packet received: 5
+Sending packet: $Hgp726d.726d#53...Packet received: OK
Sending packet: $m400680,40#2f...Packet received: 85c0741455bff00d60004889e5ffd05de97bffffff0f1f00e973ffffff0f1f00554889e5c745fc00000000c745fc01000000e900000000c745fc02000000b800
+Sending packet: $Hgp726d.7278#28...Packet received: OK
Sending packet: $m4006b2,1#28...Packet received: e9

This ended up breaking "tstart" when one has fast tracepoints set,
because gdbserver isn't expecting an Hg packet in response to
qRelocInsn:
(gdb) ftrace *set_point
Fast tracepoint 3 at 0x4006b2: file gdb/testsuite/gdb.trace/range-stepping.c, line 53.
(gdb) PASS: gdb.trace/range-stepping.exp: ftrace: ftrace *set_point
tstart
gdbserver: Malformed response to qRelocInsn, ignoring: Hgp2783.2783
Target does not support this command.
(gdb) FAIL: gdb.trace/range-stepping.exp: ftrace: tstart
remote_trace_start should probably start by making sure the remote
current thread matches inferior_ptid (calling set_general_thread), but
still, reducing unnecessary bouncing is a good idea. It happens
because the memory/symbol/breakpoint routines use
switch_to_program_space_and_thread to do something in the right
context and then revert back to the previously current thread.
The fix is to simply make any_thread_of_process,
find_inferior_for_program_space, etc. give preference to the current
thread/inferior it if matches.
