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.

for remote target
With test-case gdb.python/py-autoloaded-pretty-printers-in-newobjfile-event.exp
and target board remote-gdbserver-on-localhost, I run into:
...
FAIL: $exp: runto: run to main
...
I can easily fix this using "gdb_load_shlib $binfile_lib", but then run into:
...
(gdb) print all_good^M
$1 = false^M
(gdb) FAIL: $exp: print all_good
info pretty-printer^M
...
Sysroot is set to "target:", so gdb downloads the shared library from the target
(Using $so as shorthand for
libpy-autoloaded-pretty-printers-in-newobjfile-event.so):
...
Reading /home/remote-target/$so from remote target...^M
...
and internally refers to it as "target:/home/remote-target/$so".
In load_auto_scripts_for_objfile, gdb gives up trying to auto-load scripts
for $so once it checks for is_target_filename.
Fix this by declaring auto-load unsupported if sysroot starts with "target:".
Tested on x86_64-linux.

The command has no effect for the loading of GDB pretty printers and is
removed by this patch to avoid confusion.
Documentation for "set print pretty"
"Cause GDB to print structures in an indented format with one member per line"

This changes skip_python_tests to invert the sense, and renames it to
allow_python_tests.

This changes various tests to use "require" for the Python feature.

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.

... make runto_main not pass no-message to runto. This means that if we
fail to run to main, for some reason, we'll emit a FAIL. This is the
behavior we want the majority of (if not all) the time.
Without this, we rely on tests logging a failure if runto_main fails,
otherwise. They do so in a very inconsisteny mannet, sometimes using
"fail", "unsupported" or "untested". The messages also vary widly.
This patch removes all these messages as well.
Also, remove a few "fail" where we call runto (and not runto_main). by
default (without an explicit no-message argument), runto prints a
failure already. In two places, gdb.multi/multi-re-run.exp and
gdb.python/py-pp-registration.exp, remove "message" passed to runto.
This removes a few PASSes that we don't care about (but FAILs will still
be printed if we fail to run to where we want to). This aligns their
behavior with the rest of the testsuite.

Without any explicit dependencies specified, the observers attached
to the 'gdb::observers::new_objfile' observable are always notified
in the order in which they have been attached.
The new_objfile observer callback to auto-load scripts is attached in
'_initialize_auto_load'.
The new_objfile observer callback that propagates the new_objfile event
to the Python side is attached in 'gdbpy_initialize_inferior', which is
called via '_initialize_python'.
With '_initialize_python' happening before '_initialize_auto_load',
the consequence was that the new_objfile event was emitted on the Python
side before autoloaded scripts had been executed when a new objfile was
loaded.
As a result, trying to access the objfile's pretty printers (defined in
the autoloaded script) from a handler for the Python-side
'new_objfile' event would fail. Those would only be initialized later on
(when the 'auto_load_new_objfile' callback was called).
To make sure that the objfile passed to the Python event handler
is properly initialized (including its 'pretty_printers' member),
make sure that the 'auto_load_new_objfile' observer is notified
before the 'python_new_objfile' one that propagates the event
to the Python side.
To do this, make use of the mechanism to explicitly specify
dependencies between observers (introduced in a preparatory commit).
Add a corresponding testcase that involves a test library with an autoloaded
Python script and a handler for the Python 'new_objfile' event.
(The real world use case where I came across this issue was in an attempt
to extend handling for GDB pretty printers for dynamically loaded
objfiles in the Qt Creator IDE, s. [1] and [2] for more background.)

Tested on x86_64-linux (Debian testing).
gdb/ChangeLog:
* gdb/auto-load.c (_initialize_auto_load): 'Specify token
when attaching the 'auto_load_new_objfile' observer, so
other observers can specify it as a dependency.
* gdb/auto-load.h (struct token): Declare
'auto_load_new_objfile_observer_token' as token to be used
for the 'auto_load_new_objfile' observer.
* gdb/python/py-inferior.c (gdbpy_initialize_inferior): Make
'python_new_objfile' observer depend on 'auto_load_new_objfile'
observer, so it gets notified after the latter.
gdb/testsuite/ChangeLog:
* gdb.python/libpy-autoloaded-pretty-printers-in-newobjfile-event.so-gdb.py: New test.
