After the previous target_ops/C++ patches are all squashed and merged,
this one can go in separately.
This patch adjusts all the target methods to return bool instead of int
when they're returning a boolean.

From: Pedro Alves @ 2018-04-14 19:10 UTC (permalink / raw)
To: gdb-patches
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between the
different BSDs. Current, all that is stiched together to form a final
target, via the i386bsd_target, x86bsd_target, fbsd_nat_add_target
functions etc.
Introduces generic i386/AMD64 BSD targets, to be used as template
mixin to build a final target.

Before the target_ops C++ification, this wasn't necessary simply
because the methods were wrapped in ()'s, like
'(*to_my_long_method_name) (target_ops *)',
so
std::vector<long_type_name>(*to_my_long_method_name) ()TARGET_DEFAULT_IGNORE ()
still parsed correctly. With the (*) gone, we need this.
gdb/ChangeLog:
yyyy-mm-dd Pedro Alves <palves@redhat.com>
* make-target-delegates (scan_target_h): Don't trim lines here.
Replace sequences of tabs and/or whitespace with a single
whitespace.
(top level, parsing methods): Trim each line before processing it
here.

From: Pedro Alves @ 2018-04-14 19:10 UTC (permalink / raw)
To: gdb-patches
Currently, to open a target, with "target TARGET_NAME", GDB finds the
target_ops instance with "TARGET_NAME" as short name, and then calls
its target_ops::open virtual method. In reality, there's no actual
target/name lookup, a pointer to the target_ops object was associated
with the "target TARGET_NAME" command at add_target time (when GDB is
initialized), as the command's context.
This creates a chicken and egg situation. Consider the case of
wanting to open multiple remote connections. We want to be able to
have one remote target_ops instance per connection, but, if we're not
connected yet, so we don't yet have an instance to call target->open()
on...
This patch fixes this by separating out common info about a target_ops
to a separate structure (shortname, longname, doc), and changing the
add_target routine to take a reference to such an object instead of a
pointer to a target_ops, and a pointer to a factory function that is
responsible to open an instance of the corresponding target when the
user types "target TARGET_NAME".
-extern void add_target (struct target_ops *);
+extern void add_target (const target_info &info, target_open_ftype *func);
I.e. this factory function replaces the target_ops::open virtual
method.
For static/singleton targets, nothing changes, the target_open_ftype
function pushes the global target_ops instance on the target stack.
At target_close time, the connection is tor down, but the global
target_ops object remains live.
However, targets that support being open multiple times will make
their target_open_ftype routine allocate a new target_ops instance on
the heap [e.g., new remote_target()], and push that on the stack. At
target_close time, the new object is destroyed (by the
target_ops::close virtual method).
Both the core target and the remote targets will support being open
multiple times (others could/should too, but those were my stopping
point), but not in this patch yet. We need to get rid of more globals
first before that'd be useful.
Native targets are somewhat special, given find_default_run_target &
friends. Those routines also expect to return a target_ops pointer,
even before we've open the target. However, we'll never need more
than one instance of the native target, so we can assume/require that
native targets are global/simpletons, and have the backends register a
pointer to the native target_ops. Since all native targets inherit
inf_child_target, we can centralize that registration. See
add_inf_child_target, get_native_target/set_native_target and
find_default_run_target.

From: Pedro Alves @ 2018-04-14 19:10 UTC (permalink / raw)
To: gdb-patches
This converts the remaining linux-nat.c hooks low_ methods like had
been started in a previous patch. The linux_nat_set_foo routines are
all gone with this.
gdb/ChangeLog:
yyyy-mm-dd Pedro Alves <palves@redhat.com>
* linux-nat.h (linux_nat_target) <low_new_thread,
low_delete_thread, low_new_fork, low_forget_process,
low_prepare_to_resume, low_siginfo_fixup, low_status_is_event>:
New virtual methods.
(linux_nat_set_new_thread, linux_nat_set_delete_thread)
(linux_nat_new_fork_ftype, linux_nat_set_new_fork)
(linux_nat_forget_process_ftype, linux_nat_set_forget_process)
(linux_nat_forget_process, linux_nat_set_siginfo_fixup)
(linux_nat_set_prepare_to_resume, linux_nat_set_status_is_event):
Delete.
* linux-fork.c (delete_fork): Adjust to call low method.
* linux-nat.c (linux_nat_new_thread, linux_nat_delete_thread)
(linux_nat_new_fork, linux_nat_forget_process_hook)
(linux_nat_prepare_to_resume, linux_nat_siginfo_fixup)
(linux_nat_status_is_event):
(linux_nat_target::follow_fork, lwp_free, add_lwp, detach_one_lwp)
(linux_resume_one_lwp_throw, linux_handle_extended_wait): Adjust
to call low method.
(sigtrap_is_event): Rename to ...
(linux_nat_target::low_status_is_event): ... this.
(linux_nat_set_status_is_event): Delete.
(save_stop_reason, linux_nat_wait_1)
(linux_nat_target::mourn_inferior, siginfo_fixup): Adjust to call
low methods.
(linux_nat_set_new_thread, linux_nat_set_delete_thread)
(linux_nat_set_new_fork, linux_nat_set_forget_process)
(linux_nat_forget_process, linux_nat_set_siginfo_fixup)
(linux_nat_set_prepare_to_resume): Delete.
* aarch64-linux-nat.c: All linux_nat_set_* callbacks converted to
low virtual methods.
* amd64-linux-nat.c: Likewise.
* arm-linux-nat.c: Likewise.
* i386-linux-nat.c: Likewise.

From: Pedro Alves @ 2018-04-14 19:19 UTC (permalink / raw)
To: gdb-patches
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between the
different BSDs. Current, all that is stiched together to form a final
target, via the i386bsd_target, x86bsd_target, fbsd_nat_add_target
functions etc.
Introduces a fbsd_nat_target base/prototype target. To be used in
following patches.

I will do some tests of FreeBSD/amd64 first and let you know what I find.

Do we want to be consistent about whether or not to have comments for
#endif's? Most in this change don't but these two do.
(Also, my initial impression is that the #ifdef's are more readable in this
version than the current code)

I think I have added the one for PT_LWPINFO thinking that the
corresponding #ifdef is so far away, and then added the one just
above too, while missing the others.
I don't have a strong opinion on whether all should have the
comment, I'm fine either way since the #ifdef blocks are small,
i.e., removing the comment for HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE
is totally fine with me and may even reduce noise. I do think
the comment for "#endif PT_LWPINFO" is beneficial, however.

Yeah, the #endif for PT_LWPINFO is the one that I think I
recall gave me pause in the current code.

Common BSD target should be changed in future to common BSD/Linux target
like in LLDB. There is a shared Remote Process Plugin used by Linux and
NetBSD.
Enforcing a layer of common BSD code is counterproductive nowadays.

Hi Kamil!
Will you be able to smoke test the branch on your favorite
port? That'd be super. :-)

I think that is confusing or oversimplifying things. Also, it's
a bit orthogonal to the present effort. :-) The "shared" Remote
Process Plugin is just the equivalent of "target remote" in gdb.
See:
https://sourceware.org/gdb/wiki/Common
https://sourceware.org/gdb/wiki/LocalRemoteFeatureParity
What we're missing is that gdbserver was never ported over to the
BSDs. At least, upstream. Just like in lldb not all ports
have been converted to use the remote process plugin.
Clearly there needs to be a shared interface the different target
backends such as BSD and Linux implement to interact with the
core of the debugger or the server. In gdb and gdbserver that is
their corresponding target_ops definitions (they're similar, but
not the same). So even when "going always remote", the target
backend implementations can well share code.
If you're considering porting gdbserver to some platform that
gdb already supports debugging natively, I strongly suggest
making gdbserver reuse the native target code in gdb instead of
duplicating the code. A few years back someone was working
on doing that for a Hurd gdbserver port, but unfortunately
the work was never completed. I was positively surprised how
little change the gdb code was requiring for gdbserver
adaptation though.
If done right (by making gdb and gdbserver use the same native
backend target_ops-like interface), there's nothing preventing using
the same backend code in-process in both gdb and gdbserver if we'd like,
instead of always forcing use of gdbserver behind the scenes. There
are advantages to supporting native-without-forcing-gdbserver
debugging too. It's all open in the air at this point.
> Enforcing a layer of common BSD code is counterproductive nowadays.
Note that nothing is being "enforced" and that there's no actual
"common BSD layer" in the sense that everything sits on top of some
common BSD layer. There are simply a few pieces of shared functionality.
If some BSD port doesn't want to use the shared bits, it's very easy
not to use them.
Thanks,
Pedro Alves

My comment was rather orthogonal to the process plugin model. I wanted
to state that FreeBSD and NetBSD diverged, while NetBSD was trying to
follow FreeBSD / Linux API with a clean room design.
Cloning 1:1: other BSD would require breakage in existing software as
the APIs were already incompatible. For example PT_LWPINFO has a
different meaning on FreeBSD (get thread info with trap details) and
NetBSD (iterate over threads in tracee).
This means that we are today a distinct target. It's an open question
about OpenBSD, they could follow NetBSD with marginal differences...
once we could convince them to sync up with proper support in debuggers.

There was a port of gdbserver to NetBSD, perhaps so old that it's no
longer relevant today (code from 2010).
http://gnats.netbsd.org/43332 gdbserver for powerpc
Right now, I'm busy with kernel work improving correctness of
forking-like code in the context of debuggers, it will be followed by
signals and threads. It's mostly a one-man show as of today... so it's a
process taking time. I'm reporting the monthly progress on blog.netbsd.org.

I've pushed a target_ops-cxx branch to github.com/bsdjhb/gdb.git that has
some small fixups (compile fixes). I've built the amd64, i386, arm, and
aarch64 FreeBSD native targets so far. Simple testing of the the amd64
and i386 binaries seems to work, but I encountered a new test failure
in the testsuite for FreeBSD/amd64 that is a bit odd. In particular,
I get a core dump running 'info set' when it tries to display the
current setting of whether ASLR is disabled. Looking at the core of gdb:
Program terminated with signal SIGSEGV, Segmentation fault.

...
The native target isn't currently in the target_stack so its 'beneath' is
NULL:
(top-gdb) p beneath
During symbol reading, missing name for subprogram DIE at 14709647.
$1 = (target_ops *) 0x0
(top-gdb) p target_stack
$2 = (target_ops *) 0x8040d6060
(top-gdb) p *target_stack
$3 = {_vptr$target_ops = 0x183aaf0 <vtable for dummy_target+16>,
beneath = 0x0, to_stratum = dummy_stratum}
From the stack trace we can see that it already bounced down to the dummy
target which calls find_default_supports_disable_randomization. That
finds the native "run" target and invokes its method without pushing
it onto the stack. I think before if a native target didn't support ASLR
at all it just didn't set the function pointer and no harm was done.
Now the function pointer is effectively always set but to something that
assumes 'beneath' is valid. I'm not quite sure how you want to fix this.
The simple solution is to change the default method to return false if
beneath is NULL, but I'm not quite sure that fits in with the design this
branch is aiming for.

I've checked this branch on NetBSD/amd64 8.99.7 (target_ops-cxx
github.com/bsdjhb/gdb.git). It builds and it's not fully functional..
perhaps not much different to previous versions, for I'm not going to
open new threads and focus on kernel fixes.

Ah, I wasn't seeing this because the Linux target implements
the supports_disable_randomization method. If I hack that away, I
can reproduce the crash.

Thanks for the analysis, that helps.
There's a small set of target methods that must always be
implemented by native targets, to avoid falling down to the
target beneath (since the target may not be pushed when the
method is called). See target.c:complete_target_initialization
in current master. Since all native targets inherit from inf-child
(just like in current master), in the C++ version, we can override
it there. Like below. This fixes it for me.

I've now merged/squashed those fixes to the patches in the branch,
and added your name to the WIP ChangeLog entry.
I diff my branch against yours to double-checked whether I was
missing anything, then rebased on top of current master.
I force-pushed the result to users/palves/target_ops-cxx on sourceware.org.
Thanks again.

Thanks for the explanation of the proper fix. I've pulled the updated branch
and FreeBSD/amd64 has basically the same test results as master now. (There
are a few differences but I think they are due to timing issues/races in the
tests rather than actual behavioral differences.) There are a few other
platforms I haven't built yet (FreeBSD/mips and FreeBSD/powerpc) but I'm fine
with fixing those post-commit if there are any fixes needed. If I am able to
test them before you merge this in I'll send you any needed patches.

Straighforward conversion. I'd tested this with a cross compiler.

From: Pedro Alves @ 2018-04-14 19:20 UTC (permalink / raw)
To: gdb-patches
This is a first pass, just enough to C++ify target_ops.
A later pass will convert more free functions to methods, and make the
remote_state be truly per remote instance, allowing multiple
simultaneous instances of remote targets.

From: Pedro Alves @ 2018-04-14 19:20 UTC (permalink / raw)
To: gdb-patches
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between the
different BSDs. Current, all that is stiched together to form a final
target, via the i386bsd_target, x86bsd_target, fbsd_nat_add_target
functions etc.
This patch converts the rest of the BSD targets to C++ified target_ops.
Adds new obsd_nat_target and nbsd_nat_target targets similar to
fbsd_nat_target introduced a couple patches ago, a sparc_target mixin
similar to the one introduced in the previous patch for x86, and then
stiches everything together into final targets.
Unfortunately, I'm not able to test most of this. I was able to build
GDB for AMD64 NetBSD on the compile farm, but that's it.

No problem :-) I've checked the fix in now.

To: gdb-patches
This converts the x86/AMD64 GNU/Linux ports to C++ified target_ops.
- inf-child/"native" is converted to an actual base class
(inf_child_target), that is inherited by the linux-nat target.
inf_child_target will be inherited by all other native targets too,
of course, in the following patches.
- The old weird double-target linux_ops mechanism in linux-nat.c, is
gone, replaced by adding a few virtual methods to linux-nat.h's
target_ops, called low_XXX, that the concrete linux-nat
implementations override. Sort of like gdbserver's
linux_target_ops, but simpler, for requiring only one
target_ops-like hierarchy, which spares implementing the same method
twice when we need to forward the method to a low implementation.
The low target simply reimplements the target_ops method directly in
that case.
There are a few remaining linux-nat.c hooks that would be better
converted to low_ methods like above too. E.g.:
linux_nat_set_new_thread (t, x86_linux_new_thread);
linux_nat_set_new_fork (t, x86_linux_new_fork);
linux_nat_set_forget_process
That'll be done in a follow up patch.
- We can no longer use functions like x86_use_watchpoints to install
custom methods on an arbitrary base target. The patch replaces that
with a template mixin. See x86_nat_target in x86-nat.h. That will
be used by other non-Linux x86 targets in following patches.
- linux-thread-db is converted here too.

From: Pedro Alves @ 2018-04-14 19:30 UTC (permalink / raw)
To: gdb-patches
This converts the code in the new linux-nat-trad.h/c files, that was
split off of inf-ptrace.h/c recently, to a C++ base class, and makes
the MIPS and Alpha GNU/Linux ports use it.
Otherwise, it's a straighforward conversion.
I'd checked with a cross compiler that the MIPS port builds. I don't
have an Alpha compiler handy.

I'm not sure why, but PATCH 01/40 never made it to the list.
Maybe because it's too large (the patch file is 477K).
Here's the same patch, but without the (generated)

Subject: [PATCH 01/40] Convert struct target_ops to C++
I.e., use C++ virtual methods and inheritance instead of tables of
function pointers.
Unfortunately, there's no way to do a smooth transition. ALL native
targets in the tree must be converted at the same time. I've tested
all I could with cross compilers and with help from GCC compile farm,
but naturally I haven't been able to test many of the ports. Still, I
made a best effort to port everything over, and while I expect some
build problems due to typos and such, which should be trivial to fix,
I don't expect any design problems. Since the patch would be too big
to review and manage as a single unit, I split it in many chunks.
This patch contains the core changes. The following patches that have
"target_ops/C++:" in their subject line each converts some target or
targets over. For pushing, all the "target_ops/C++:" patches must be
squashed into this patch and pushed together, to avoid breaking the
build (as much as possible). I also haven't written ChangeLog entries
for this part of the series yet, because it's going to be very
mechanical, and I'd rather send this out sooner than later, in order
to hopefuly get some help with testing on native ports that I don't
have access to.
* Implementation notes:
- The flattened current_target is gone. References to current_target
or current_target.beneath are replaced to references to target_stack
(the top of the stack) directly.
- To keep "set debug target" working, This adds a new debug_stratum
layer that sits on top of the stack, prints the debug, and delegates
to the target beneath.
In addition, this makes the shortname and longname properties of
target_ops be virtual methods instead of data fields, and makes the
debug target defer those to the target beneath. This is so that
debug code sprinkled around that does "if (debugtarget) ..." can
transparently print the name of the target beneath.
A patch later in the series actually splits out the
shortname/longname methods to a separate structure, but I preferred
to keep that chance separate as it is associated with changing a bit
the design of how targets are registered and open.
- Since you can't check whether a C++ virtual method is overriden, the
old method of checking whether a target_ops implements a method by
comparing the function pointer must be replaced with something else.
This is fixed by adding a parallel "can_do_foo" target_ops methods.
E.g.,:
+ for (t = target_stack; t != NULL; t = t->beneath)
{
- if (t->to_create_inferior != NULL)
+ if (t->can_create_inferior ())
break;
}
- make-target-delegates was adjusted to generate C++ classes and
methods.
It needed tweaks to grok "virtual" in front of the target method
name, and for the fact that methods are no longer function pointers.
(In particular, the current code parsing the return type was simple
because it could simply parse up until the '(' in '(*to_foo)'.
It now generates a couple C++ classes that inherit target_ops:
dummy_target and debug_target.
Since we need to generate the class declarations as well, i.e., we
need to emit methods twice, we now generate the code in two passes.
- We can no longer use functions like x86_use_watchpoints to install
custom methods on an arbitrary base target.
The patch (actually patches until it's all squashed before pushing)
replaces instances of such a pattern with template mixins. A case
seen in this patch in isolation is memory_breakpoint_target defined
in target.h.

I've now written the ChangeLog entries, squashed all the
"target_ops/C++:" patches into this one, and pushed the whole series
in.
For the record, below is what the commit looks like, git log + ChangeLog.
The actual patch is elided.

Subject: [PATCH] Convert struct target_ops to C++
I.e., use C++ virtual methods and inheritance instead of tables of
function pointers.
Unfortunately, there's no way to do a smooth transition. ALL native
targets in the tree must be converted at the same time. I've tested
all I could with cross compilers and with help from GCC compile farm,
but naturally I haven't been able to test many of the ports. Still, I
made a best effort to port everything over, and while I expect some
build problems due to typos and such, which should be trivial to fix,
I don't expect any design problems.
* Implementation notes:
- The flattened current_target is gone. References to current_target
or current_target.beneath are replaced with references to
target_stack (the top of the stack) directly.
- To keep "set debug target" working, this adds a new debug_stratum
layer that sits on top of the stack, prints the debug, and delegates
to the target beneath.
In addition, this makes the shortname and longname properties of
target_ops be virtual methods instead of data fields, and makes the
debug target defer those to the target beneath. This is so that
debug code sprinkled around that does "if (debugtarget) ..." can
transparently print the name of the target beneath.
A patch later in the series actually splits out the
shortname/longname methods to a separate structure, but I preferred
to keep that chance separate as it is associated with changing a bit
the design of how targets are registered and open.
- Since you can't check whether a C++ virtual method is overridden,
the old method of checking whether a target_ops implements a method
by comparing the function pointer must be replaced with something
else.
Some cases are fixed by adding a parallel "can_do_foo" target_ops
methods. E.g.,:
+ for (t = target_stack; t != NULL; t = t->beneath)
{
- if (t->to_create_inferior != NULL)
+ if (t->can_create_inferior ())
break;
}
Others are fixed by changing void return type to bool or int return
type, and have the default implementation return false or -1, to
indicate lack of support.
- make-target-delegates was adjusted to generate C++ classes and
methods.
It needed tweaks to grok "virtual" in front of the target method
name, and for the fact that methods are no longer function pointers.
(In particular, the current code parsing the return type was simple
because it could simply parse up until the '(' in '(*to_foo)'.
It now generates a couple C++ classes that inherit target_ops:
dummy_target and debug_target.
Since we need to generate the class declarations as well, i.e., we
need to emit methods twice, we now generate the code in two passes.
- The core_target global is renamed to avoid conflict with the
"core_target" class.
- ctf/tfile targets
init_tracefile_ops is replaced by a base class that is inherited by
both ctf and tfile.
- bsd-uthread
The bsd_uthread_ops_hack hack is gone. It's not needed because
nothing was extending a target created by bsd_uthread_target.
- remote/extended-remote targets
This is a first pass, just enough to C++ify target_ops.
A later pass will convert more free functions to methods, and make
remote_state be truly per remote instance, allowing multiple
simultaneous instances of remote targets.
- inf-child/"native" is converted to an actual base class
(inf_child_target), that is inherited by all native targets.
- GNU/Linux
The old weird double-target linux_ops mechanism in linux-nat.c, is
gone, replaced by adding a few virtual methods to linux-nat.h's
target_ops, called low_XXX, that the concrete linux-nat
implementations override. Sort of like gdbserver's
linux_target_ops, but simpler, for requiring only one
target_ops-like hierarchy, which spares implementing the same method
twice when we need to forward the method to a low implementation.
The low target simply reimplements the target_ops method directly in
that case.
There are a few remaining linux-nat.c hooks that would be better
converted to low_ methods like above too. E.g.:
linux_nat_set_new_thread (t, x86_linux_new_thread);
linux_nat_set_new_fork (t, x86_linux_new_fork);
linux_nat_set_forget_process
That'll be done in a follow up patch.
- We can no longer use functions like x86_use_watchpoints to install
custom methods on an arbitrary base target.
The patch replaces instances of such a pattern with template mixins.
For example memory_breakpoint_target defined in target.h, or
x86_nat_target in x86-nat.h.
- linux_trad_target, MIPS and Alpha GNU/Linux
The code in the new linux-nat-trad.h/c files which was split off of
inf-ptrace.h/c recently, is converted to a C++ base class, and used
by the MIPS and Alpha GNU/Linux ports.
- BSD targets
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between
the different BSDs. Currently, all that is stiched together to form
a final target, via the i386bsd_target, x86bsd_target,
fbsd_nat_add_target functions etc.
This introduces new fbsd_nat_target, obsd_nat_target and
nbsd_nat_target classes that serve as base/prototype target for the
corresponding BSD variant.
And introduces generic i386/AMD64 BSD targets, to be used as
template mixin to build a final target. Similarly, a generic SPARC
target is added, used by both BSD and Linux ports.
- bsd_kvm_add_target, BSD libkvm target
I considered making bsd_kvm_supply_pcb a virtual method, and then
have each port inherit bsd_kvm_target and override that method, but
that was resulting in lots of unjustified churn, so I left the
function pointer mechanism alone.

As you know I worked on this a bit, without success, a few years ago. I
think your approach is definitely the way to go.

Thanks Tom. I wouldn't say without success at all -- you finished
important groundwork at the time, like for example all the
delegation cleaning up and normalization. Remember that 200 patch
series? :-) And of course the ideas on my branch draw lessons from
your earlier experiments.
Thanks,
Pedro Alves

Hi Pedro,
It's kind of difficult to properly review this series, because the important
non-mechanical bits are lost in a sea of mechanical changes. But I didn't
find anything fundamental I would change, and all you wrote in commit logs
made sense to me.
Maybe one little comment about 40/40 (because I just finished looking at that
patch): it might be good to add an assertion (the_native_target == nullptr)
in set_native_target and one in add_target
(target_factories.find (&t) == target_factories.end ()). I think it could
help catch problems if somebody is trying to add a new target or change
existing ones.
Otherwise, I would suggest not waiting too long before merging it to
avoid having to resolve too many conflicts. Thanks a lot for doing this!
Simon

Yeah, sorry about that.

Good idea. I'm adding this to patch #40:

Alright, I wrote the missing ChangeLogs today, and will proceed with
squashing the patches that need to be squashed and getting it all in.
Thanks,
