We currently pass frames to function by value, as `frame_info_ptr`.
This is somewhat expensive:
- the size of `frame_info_ptr` is 64 bytes, which is a bit big to pass
by value
- the constructors and destructor link/unlink the object in the global
`frame_info_ptr::frame_list` list. This is an `intrusive_list`, so
it's not so bad: it's just assigning a few points, there's no memory
allocation as if it was `std::list`, but still it's useless to do
that over and over.
As suggested by Tom Tromey, change many function signatures to accept
`const frame_info_ptr &` instead of `frame_info_ptr`.
Some functions reassign their `frame_info_ptr` parameter, like:
void
the_func (frame_info_ptr frame)
{
for (; frame != nullptr; frame = get_prev_frame (frame))
{
...
}
}
I wondered what to do about them, do I leave them as-is or change them
(and need to introduce a separate local variable that can be
re-assigned). I opted for the later for consistency. It might not be
clear why some functions take `const frame_info_ptr &` while others take
`frame_info_ptr`. Also, if a function took a `frame_info_ptr` because
it did re-assign its parameter, I doubt that we would think to change it
to `const frame_info_ptr &` should the implementation change such that
it doesn't need to take `frame_info_ptr` anymore. It seems better to
have a simple rule and apply it everywhere.

`struct so_list` was recently renamed to `struct shobj` (in 3fe0dfd1604f
("gdb: rename struct so_list to shobj")). In hindsight, `solib` would
have been a better name. We have solib.c, the implementations in
solib-*.c, many functions with solib in their name, the solib_loaded /
solib_unloaded observables, etc.
Rename shobj to solib.

This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

Currently, if you step over kernel exit, you see:
stepi
[AMDGPU Wave ?:?:?:1 (?,?,?)/? exited]
Command aborted, thread exited.
(gdb)
Those '?' are because the thread/wave is already gone by the time GDB
prints the "exited" notification, we can't ask dbgapi for any info
about the wave anymore.
This commit fixes it by caching the wave's coordinates as soon as GDB
sees the wave for the first time, and making
amd_dbgapi_target::pid_to_str use the cached info.
At first I thought of clearing the wave_info object from a
thread_exited observer. However, that is too soon, resulting in this:
(gdb) si
[AMDGPU Wave 1:4:1:1 (0,0,0)/0 exited]
Command aborted, thread exited.
(gdb) thread
[Current thread is 6 (AMDGPU Wave ?:?:?:0 (?,?,?)/?) (exited)]
We need instead to clear the wave info when the thread is ultimately
deleted, so we get:
(gdb) si
[AMDGPU Wave 1:4:1:1 (0,0,0)/0 exited]
Command aborted, thread exited.
(gdb) thread
[Current thread is 6 (AMDGPU Wave 1:4:1:1 (0,0,0)/0) (exited)]
And for that, we need a new thread_deleted observable.

Since GDB now requires C++17, we don't need the internally maintained
gdb::optional implementation. This patch does the following replacing:
- gdb::optional -> std::optional
- gdb::in_place -> std::in_place
- #include "gdbsupport/gdb_optional.h" -> #include <optional>
This change has mostly been done automatically. One exception is
gdbsupport/thread-pool.* which did not use the gdb:: prefix as it
already lives in the gdb namespace.

This commit replaces the architecture_changed observer with a
new_architecture observer.
Currently the only user of the architecture_changed observer is the
Python code, which uses this observer to register the Python unwinder
with the architecture.
The problem is that the architecture_changed observer is triggered
from inferior::set_arch(), which only sees the inferior-wide gdbarch
value. For targets that use thread-specific architectures, these
never trigger the architecture_changed observer, and so never have the
Python unwinder registered with them.
When it comes to unwinding GDB makes use of the frame's gdbarch, which
is based on the thread's regcache gdbarch, which is set in
get_thread_regcache to the value returned from
target_thread_architecture, which is not always the inferiors gdbarch
value, it might be a thread-specific gdbarch which has not passed
through inferior::set_arch().
The new_architecture observer will be triggered from
gdbarch_find_by_info, whenever a new gdbarch is created and
initialised. As GDB caches and reuses gdbarch values, we should
expect to see each new architecture trigger the new_architecture
observer just once.
After this commit, targets that make use of thread-specific
architectures should be able to make use of Python unwinders.
As I don't have access to a machine that makes use of thread-specific
architectures right now, I asked Luis to confirm that an AArch64
target that uses SVE/SME can't use the Python unwinders in threads
that are using a thread-specific architectures, and he confirmed that
this is indeed the case, see this discussion:

The new_objfile observer is currently used to indicate both when a new
objfile is added to program space (when passed non-nullptr) and when all
objfiles of a program space were just removed (when passed nullptr).
I think this is confusing (and Andrew apparently thinks so too [1]).
Add a new "all_objfiles_removed" observer to remove the second role from
"new_objfile".
Some existing users of new_objfile do nothing if the passed objfile is
nullptr. For them, we can simply drop the nullptr check. For others,
add a new all_objfiles_removed callback, and refactor things a bit to
keep the existing behavior as much as possible.
Some callbacks relied on current_program_space, and following
the refactoring now use either objfile->pspace or the pspace passed to
all_objfiles_removed. I think this should be relatively safe, and in
general a step in the right direction.
On the notify side, I found only one call site to change from
new_objfile to all_objfiles_removed, in clear_symtab_users. It is not
entirely clear to me that this is entirely correct. clear_symtab_users
appears to be called in spots that don't remove all objfiles
(functions finish_new_objfile, remove_symbol_file_command, reread_symbols,
do_module_cleanups). But I think that this patch at least makes the
current code clearer.

Initially I just wanted a Python event for when GDB removes a program
space, I'm writing a Python extension that caches information for each
program space, and need to know when I should discard entries for a
particular program space.
But, it seemed easy enough to also add an event for when GDB adds a
new program space, so I went ahead and added both new events.
Of course, we don't currently have an observable for program space
addition or removal, so I first needed to add these. After that it's
pretty simple to add two new Python events and have these trigger.
The two new event registries are:
events.new_progspace
events.free_progspace
These emit NewProgspaceEvent and FreeProgspaceEvent objects
respectively, each of these new event types has a 'progspace'
attribute that contains the relevant gdb.Progspace object.
There's a couple of things to be mindful of.
First, it is not possible to catch the NewProgspaceEvent for the very
first program space, the one that is created when GDB first starts, as
this program space is created before any Python scripts are sourced.
In order to allow this event to be caught we would need to defer
creating the first program space, and as a consequence the first
inferior, until some later time. But, existing scripts could easily
depend on there being an initial inferior, so I really don't think we
should change that -- and so, we end up with the consequence that we
can't catch the event for the first program space.
The second, I think minor, issue, is that GDB doesn't clean up its
program spaces upon exit -- or at least, they are not cleaned up
before Python is shut down. As a result, any program spaces in use at
the time GDB exits don't generate a FreeProgspaceEvent. I'm not
particularly worried about this for my use case, I'm using the event
to ensure that a cache doesn't hold stale entries within a single GDB
session. It's also easy enough to add a Python at-exit callback which
can do any final cleanup if needed.
Finally, when testing, I did hit a slightly weird issue with some of
the remote boards (e.g. remote-stdio-gdbserver). As a consequence of
this issue I see some output like this in the gdb.log:
(gdb) PASS: gdb.python/py-progspace-events.exp: inferior 1
step
FreeProgspaceEvent: <gdb.Progspace object at 0x7fb7e1d19c10>
warning: cannot close "target:/lib64/libm.so.6": Cannot execute this command while the target is running.
Use the "interrupt" command to stop the target
and then try again.

and then try again.
do_parent_stuff () at py-progspace-events.c:41
41 ++global_var;
(gdb) PASS: gdb.python/py-progspace-events.exp: step
The 'FreeProgspaceEvent ...' line is expected, that's my test Python
extension logging the event. What isn't expected are all the blocks
like:
warning: cannot close "target:/lib64/libm.so.6": Cannot execute this command while the target is running.
Use the "interrupt" command to stop the target
and then try again.
It turns out that this has nothing to do with my changes, this is just
a consequence of reading files over the remote protocol. The test
forks a child process which GDB stays attached too. When the child
exits, GDB cleans up by calling prune_inferiors, which in turn can
result in GDB trying to close some files that are open because of the
inferior being deleted.
If the prune_inferiors call occurs when the remote target is
running (and in non-async mode) then GDB will try to send a fileio
packet while the remote target is waiting for a stop reply, and the
remote target will throw an error, see remote_target::putpkt_binary in
remote.c for details.
I'm going to look at fixing this, but, as I said, this is nothing to
do with this change, I just mention it because I ended up needing to
account for these warning messages in one of my tests, and it all
looks a bit weird.

This commit continues the work of the previous few commits.
My goal is to expose the executable_changed observer through the
Python API as an event.
At this point adding executable_changed as an event to the Python API
is trivial, but before I do that I would like to add some additional
arguments to the observable, which currently has no arguments at all.
The new arguments I wish to add are:
1. The program_space in which the executable was changed, and
2. A boolean flag that will indicate if the executable changed to a
whole new path, or if GDB just spotted that the executable changed on
disk (e.g. the user recompiled the executable).
In this commit I change the signature of the observable and then pass
the arguments through at the one place where this observable is
notified.
As there are (currently) no users of this observable nothing else
needs updating. In the next commit I'll add a listener for this
observable in the Python code, and expose this as an event in the
Python API.
Additionally, with this change, it should be possible to update the
insight debugger to make use of this observable rather than using the
deprecated_exec_file_display_hook (as it currently does), which will
then allow this hook to be removed from GDB.
There should be no user visible changes after this commit.

This commit fixes this by moving the thread exit printing to common
code instead, triggered from within delete_thread (or rather,
set_thread_exited).
There's one wrinkle, though. While most targest want to print:
[Thread ... exited]
the Windows target wants to print:
[Thread ... exited with code <exit_code>]
... and sometimes wants to suppress the notification for the main
thread. To address that, this commits adds a delete_thread_with_code
function, only used by that target (so far).
This fix was originally posted as part of a larger series:

In the upcoming patch to support fork in the amd-dbgapi target, the
amd-dbgapi target will need to be notified of fork events through an
observer, to attach itself (attach in the amd-dbgapi sense, not ptrace
sense) to the new inferior / process.
The reason that this can't be done through target_ops::follow_fork is
that the amd-dbgapi target isn't pushed on the inferior's target stack
right away. It attaches itself to the process and only pushes itself on
its target stack if and when the inferior initializes the ROCm runtime.
If an inferior that is not using the ROCm runtime forks, we want to be
notified of it, so we can attach to the child, and catch if the child
starts using the ROCm runtime.
So, add a new observable and notify it in follow_fork_inferior. It will
be used later in this series.

The upcoming patch to support exec in the amd-dbgapi target needs to
detach amd-dbgapi from the inferior doing the exec and attach amd-dbgapi
to the inferior continuing the execution. They may or may not be the
same, depending on the `set follow-exec-mode` setting. But even if they
are the same, we need to do the detach / attach dance.
With the current observable signature, the observers only receive the
inferior in which execution continues (the "following" inferior).
Change the signature to pass both inferiors, and update all existing
observers.

Add an observable notified in target_detach just before calling the
detach method on the inferior's target stack. This allows observer to
do some work on the inferior while it's still ptrace-attached, in the
case of a native Linux inferior. Specifically, the amd-dbgapi target
will need it in order to call amd_dbgapi_process_detach before the
process gets ptrace-detached.

sed 's/^struct frame_info;/class frame_info_ptr;/'
sed 's/struct frame_info \*/frame_info_ptr /g' - which left some
issues in a few files, that were manually fixed.
sed 's/\<frame_info \*/frame_info_ptr /g'
sed 's/frame_info_ptr $/frame_info_ptr/g' - used to remove whitespace

Commit b60cea7 (Make target_wait options use enum flags) broke
deprecated_target_wait_hook usage: there's a commit comment telling
this hook has not been converted.
Rather than trying to mend it, this patch replaces the hook by two
target_wait observers:
target_pre_wait (ptid_t ptid)
target_post_wait (ptid_t event_ptid)
Upon target_wait entry, target_pre_wait is notified with the ptid
passed to target_wait. Upon exit, target_post_wait is notified with
the event ptid returned by target_wait. Should an exception occur,
event_ptid is null_ptid.
This change benefits to Insight (out-of-tree): there's no real use of the
late hook in gdb itself.

This commit adds a new object type gdb.TargetConnection. This new
type represents a connection within GDB (a connection as displayed by
'info connections').
There's three ways to find a gdb.TargetConnection, there's a new
'gdb.connections()' function, which returns a list of all currently
active connections.
Or you can read the new 'connection' property on the gdb.Inferior
object type, this contains the connection for that inferior (or None
if the inferior has no connection, for example, it is exited).
Finally, there's a new gdb.events.connection_removed event registry,
this emits a new gdb.ConnectionEvent whenever a connection is removed
from GDB (this can happen when all inferiors using a connection exit,
though this is not always the case, depending on the connection type).
The gdb.ConnectionEvent has a 'connection' property, which is the
gdb.TargetConnection being removed from GDB.
The gdb.TargetConnection has an 'is_valid()' method. A connection
object becomes invalid when the underlying connection is removed from
GDB (as discussed above, this might be when all inferiors using a
connection exit, or it might be when the user explicitly replaces a
connection in GDB by issuing another 'target' command).
The gdb.TargetConnection has the following read-only properties:
'num': The number for this connection,
'type': e.g. 'native', 'remote', 'sim', etc
'description': The longer description as seen in the 'info
connections' command output.
'details': A string or None. Extra details for the connection, for
example, a remote connection's details might be
'hostname:port'.

In a later commit I plan to add disassembler styling. In the same way
that we have a source_styling_changed observer I would need to add a
disassembler_styling_changed observer.
However, currently, these observers would only be notified from
cli-style.c:set_style_enabled, and observed in tui-winsource.c,
tui_source_window::style_changed, as a result, having two observers
seems unnecessary right now, so, in this commit, I plan to rename
source_styling_changed to just styling_changed, then, in the later
commit, when disassembler styling is added, I can use the same
observer for both source styling, and disassembler styling.
There should be no user visible changes after this commit.

I don't find that the bpstat typedef, which hides a pointer, is
particularly useful. In fact, it confused me many times, and I just see
it as something to remember that adds cognitive load. Also, with C++,
we might want to be able to pass bpstats objects by const-reference, not
necessarily by pointer.
So, remove the bpstat typedef and rename struct bpstats to bpstat (since
it represents one bpstat, it makes sense that it is singular).

Add a new event, gdb.events.gdb_exiting, which is called once GDB
decides it is going to exit.
This event is not triggered in the case that GDB performs a hard
abort, for example, when handling an internal error and the user
decides to quit the debug session, or if GDB hits an unexpected,
fatal, signal.
This event is triggered if the user just types 'quit' at the command
prompt, or if GDB is run with '-batch' and has processed all of the
required commands.
The new event type is gdb.GdbExitingEvent, and it has a single
attribute exit_code, which is the value that GDB is about to exit
with.
The event is triggered before GDB starts dismantling any of its own
internal state, so, my expectation is that most Python calls should
work just fine at this point.
When considering this functionality I wondered about using the
'atexit' Python module. However, this is triggered when the Python
environment is shut down, which is done from a final cleanup. At
this point we don't know for sure what other GDB state has already
been cleaned up.

I want to add another action (clearing displaced stepping state) that
happens when an inferior execs. I think it would be cleaner to have an
observer for this event, rather than have infrun know about each other
sub-component.
Replace the calls to solib_create_inferior_hook and
jit_inferior_created_hook in follow_exec by observers.
gdb/ChangeLog:
* observable.h (inferior_execd): Declare new observable.
* observable.c (inferior_execd): Declare new observable.
* infrun.c (follow_exec): Notify inferior_execd observer.
* jit.c (jit_inferior_created_hook): Make static.
(_initialize_jit): Register inferior_execd observer.
* jit.h (jit_inferior_created_hook): Remove declaration.
* solib.c (_initialize_solib): Register inferior_execd observer.

I think it would make sense for the inferior_created observable to say
which inferior is being dealt with, rather than relying on it being the
current inferior.
This patch adds an inferior parameter to inferior_created, but does not
change the callbacks to use it.
gdb/ChangeLog:
* aix-thread.c (aix_thread_inferior_created): Add inferior
parameter.
* bsd-uthread.c (bsd_uthread_inferior_created): Likewise.
* dummy-frame.c (cleanup_dummy_frames): Likewise.
* jit.c (jit_inferior_created): Likewise.
* linux-thread-db.c (thread_db_inferior_created): Likewise.
* m68k-linux-tdep.c (m68k_linux_inferior_created): Likewise.
* observable.h (inferior_created): Likewise.
* ravenscar-thread.c (ravenscar_inferior_created): Likewise.
* symfile-mem.c (add_vsyscall_page): Likewise.

I noticed that non of the listeners of the inferior_created observable
used either of the arguments. Remove them. This in turn allows
removing the target parameter of post_create_inferior.
Tested only by rebuilding.

listeners.
* inferior.h (post_create_inferior): Remove target parameter.
Update all callers.

I noticed what I think is a potential bug. I did not observe it nor was
I able to reproduce it using actual debugging. It's quite unlikely,
because it involves multi-target and ptid clashes. I added selftests
that demonstrate it though.
The thread_ptid_changed observer says that thread with OLD_PTID now has
NEW_PTID. Now, if for some reason we happen to have two targets
defining a thread with OLD_PTID, the observers don't know which thread
this is about.
regcache::regcache_thread_ptid_changed changes all regcaches with
OLD_PTID. If there is a regcache for a thread with ptid OLD_PTID, but
that belongs to a different target, this regcache will be erroneously
changed.
Similarly, infrun_thread_ptid_changed updates inferior_ptid if
inferior_ptid matches OLD_PTID. But if inferior_ptid currently refers
not to the thread is being changed, but to a thread with the same ptid
belonging to a different target, then inferior_ptid will erroneously be
changed.
This patch adds a `process_stratum_target *` parameter to the
`thread_ptid_changed` observable and makes the two observers use it.
Tests for both are added, which would fail if the corresponding fix
wasn't done.
gdb/ChangeLog:
* observable.h (thread_ptid_changed): Add parameter
`process_stratum_target *`.
* infrun.c (infrun_thread_ptid_changed): Add parameter
`process_stratum_target *` and use it.
(selftests): New namespace.
(infrun_thread_ptid_changed): New function.
(_initialize_infrun): Register selftest.
* regcache.c (regcache_thread_ptid_changed): Add parameter
`process_stratum_target *` and use it.
(regcache_thread_ptid_changed): New function.
(_initialize_regcache): Register selftest.
* thread.c (thread_change_ptid): Pass target to
thread_ptid_changed observable.

Ages ago, when we switched observables to be templates, Joel asked me

This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

When the user toggles "set style enabled", the TUI should react by
redrawing the source window, if necessary. This patch implements this
behavior.
No test because the TUI is generally not tested.

clean way to force the TUI to update the source window's contents.

While working on my other scripts to deal with gdb headers, I noticed
that some files were missing include guards. I wrote a script to add
the missing ones, but found that using the obvious names for the
guards ran into clashes -- for example, gdb/nat/linux-nat.h used
"LINUX_NAT_H", but this was also the script's choice for
gdb/linux-nat.h.
So, I changed the script to normalize all include guards in gdb. This
patch is the result.
As usual the script is available here:
https://github.com/tromey/gdb-refactoring-scripts
Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the
