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.

This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.

This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.

Re-format all Python files using black [1] version 21.4b0. The goal is
that from now on, we keep all Python files formatted using black. And
that we never have to discuss formatting during review (for these files
at least) ever again.
One change is needed in gdb.python/py-prettyprint.exp, because it
matches the string representation of an exception, which shows source
code. So the change in formatting must be replicated in the expected
regexp.
To document our usage of black I plan on adding this to the "GDB Python
Coding Standards" wiki page [2]:
--8<--
All Python source files under the `gdb/` directory must be formatted
using black version 21.4b0.
This specific version can be installed using:
$ pip3 install 'black == 21.4b0'
All you need to do to re-format files is run `black <file/directory>`,
and black will re-format any Python file it finds in there. It runs
quite fast, so the simplest is to do:
$ black gdb/
from the top-level.
If you notice that black produces changes unrelated to your patch, it's
probably because someone forgot to run it before you. In this case,
don't include unrelated hunks in your patch. Push an obvious patch
fixing the formatting and rebase your work on top of that.

Once this is merged, I plan on setting a up an `ignoreRevsFile`
config so that git-blame ignores this commit, as described here:
https://github.com/psf/black#migrating-your-code-style-without-ruining-git-blame
I also plan on working on a git commit hook (checked in the repo) to
automatically check the formatting of the Python files on commit.

The current mechanism by which the Python gdb.current_objfile is
maintained does not allow for nested auto-load events. It is assumed
that once an auto-load script has finished loading then the current
objfile should be set back to NULL. In a nested situation, we should
be restoring the previous value.
We already have an RAII class to handle save/restore type behaviour,
so lets just switch to use that.
The test is a little contrived, but is simple enough, and triggers the
bug. The real use case might involve the auto-load script calling
functions (either in the just-loaded object file, or in the main
executable), which in turn trigger further auto-loads to occur.
gdb/ChangeLog:
* python/python.c (gdbpy_source_objfile_script): Use
make_scoped_restore to restore gdbpy_current_objfile.
(gdbpy_execute_objfile_script): Likewise.
gdb/testsuite/ChangeLog:
* gdb.python/py-auto-load-chaining-f1.c: New file.
* gdb.python/py-auto-load-chaining-f1.o-gdb.py: New file.
* gdb.python/py-auto-load-chaining-f2.c: New file.
